Detailed ways

<Embodiment 1>

Hereinafter, the diaper according to Embodiment 1 of the present invention will be described with reference to the drawings. In addition, the structure of the following embodiment is an illustration, and this invention is not limited to the structure of these embodiment.

FIG. 1 is an example of a perspective view of an adult underpants-type disposable diaper (hereinafter, simply referred to as “diaper”) according to Embodiment 1. As shown in FIG. In a diaper, let the direction which connects the front body arrange|positioned facing a wearer's abdomen, and the back body arrange|positioned facing a back be a longitudinal direction (also called a front-back direction). The crotch portion disposed on the wearer's crotch (disposed opposite to the crotch) is located between the front body (one side in the longitudinal direction) and the back body (the other side in the longitudinal direction) (the center in the longitudinal direction). In addition, when the diaper is worn on the wearer, the side facing the wearer's skin is referred to as the skin side, and the side opposite to the skin side is referred to as the non-skin side. And let the direction connecting the skin side and the non-skin side be the thickness direction, and let the direction perpendicular to both the longitudinal direction and the thickness direction be the width direction (also referred to as the left-right direction). In addition, observation from the thickness direction was made into planar observation. The diaper 1 has a length along the longitudinal direction and a width along the width direction perpendicular to the longitudinal direction, and is worn toward the crotch of the wearer. In addition, the term about a direction used in this application means the direction which matches the front, back, left, and right of the wearer in the state which the diaper 1 was worn on the wearer. For example, when saying the left-right direction in this application, it means the direction which matches the right and left of the wearer in the state in which the diaper 1 was worn on the wearer.

In this embodiment, as an example of an absorbent article, one having a waist opening through which the wearer's abdomen can be inserted and a pair of left and right leg openings through which the wearer's left and right lower limbs can be inserted is exemplified. A pant-type disposable diaper with a cylindrical structure. In addition, in this embodiment, the underpants type disposable diaper for adults is illustrated, but the "absorbent article" said in this application is not limited to the underpants type disposable diaper for adults. The term "absorbent article" in this application includes a pull-on type disposable diaper for children.

Diaper 1 has: crotch region 1B, is the position corresponding to the crotch that covers the wearer's genitals (crotch) under the wearing state; to cover the abdomen side of the wearer; and the back body region 1R is a part corresponding to the back body at the waist of the wearer, and is used to cover the back side of the wearer. Here, the front body region 1F is positioned on the front side of the crotch region 1B, and the back body region 1R is positioned on the rear side of the crotch region 1B. The diaper 1 in this embodiment is an underpants type disposable diaper, so the left side edge of the front body region 1F and the left side edge of the back body region 1R are joined to each other, and the right side edge of the front body region 1F and the back body region The edges on the right side of 1R are joined together. Thus, in the diaper 1 , the trunk opening 2T (an example of the "waist opening" in the present disclosure) is formed by the upper edge of the front body region 1F and the upper edge of the back body region 1R. In addition, in the diaper 1 , a left lower limb opening 2L is formed on the left side of the crotch region 1B that is not joined, and a right lower limb opening 2R is formed on the right side of the crotch region 1B. And, if the diaper 1 is worn in such a way that the wearer's left lower limb is inserted into the left lower limb opening 2L, the wearer's right lower limb is inserted into the right lower limb opening 2R, and the wearer's trunk enters the trunk opening 2T, then The front body region 1F is arranged on the abdomen side of the wearer, the rear body region 1R is arranged on the wearer's back side, and the left lower limb opening 2L and the right lower limb opening 2R are fixed to the wearer's body in a state surrounding the wearer's thigh. . Since the diaper 1 is fixed to the wearer's body in this manner, the wearer can move freely while wearing the diaper 1 . In addition, 2 L of left lower limb opening parts and 2 R of right lower limb opening parts are an example of "two leg circumference opening parts" of this indication.

In the diaper 1, the absorber capable of absorbing and holding liquid is arranged mainly around the crotch region 1B vicinity. In addition, in the diaper 1, in order to suppress the formation of a gap that becomes a liquid outflow path between the diaper 1 and the wearer's skin, three-dimensional gathers are provided at the left lower limb opening 2L surrounding the thigh of the wearer's left lower limb. 3BL, three-dimensional gathers (not shown) are provided at the right lower limb opening 2R surrounding the thigh of the wearer's right lower limb, and waist gathers 3R and belly gathers 12 are provided at the position surrounding the wearer's abdominal circumference . In addition, leg gathers 3LF and 3LR are provided at positions surrounding the bases of the wearer's legs (the leg gathers 3LR are not shown in FIG. 1 ). In addition, the leg gathers 3LF are provided in the front body region 1F, and the leg gathers 3LR are provided in the rear body region 1R. In addition, in FIG. 1 , only the leg gather 3LF is shown as an example. The three-dimensional gathers 3BL, 3BR, and the waist gathers 3R are contracted by the elastic force of the stretch member, and come into close contact with the wearer's skin. In addition, leg gathers 3LF, 3LR prevent gaps from being generated between the bases of the wearer's legs and the diaper 1 . Thereby, the exudate discharged from the wearer's private part is absorbed by the absorber of the diaper 1 without leaking from the diaper 1 .

In addition, the diaper 1 can be used in combination with the inner pad which is not shown in figure. The inner pad is a substantially rectangular absorbent article provided with an absorber, and absorbs exudate from the wearer. When using the diaper 1 and the inner pad in combination, the inner pad is placed on the skin surface side of the diaper 1 so as to be in contact with the wearer's discharge hole. The discharge liquid is first absorbed by the inner pad, and only the discharge liquid that cannot be absorbed by the inner pad reaches the absorber of the diaper 1 and is further absorbed. Therefore, even when the amount of the discharged liquid is large, it is possible to prevent the discharged liquid from leaking from the diaper 1 . In addition, when the amount of discharged liquid is small and can be fully absorbed by the inner pad, even if the discharged liquid is discharged, only the inner pad needs to be replaced, so that the maintenance cost can be reduced. Moreover, it is possible to use the diaper 1 for a long time by reducing the frequency of replacement of the diaper 1 .

FIG. 2 is an example of an exploded perspective view of the diaper 1 according to the first embodiment. The diaper 1 has a cover sheet 4 and an inner cover sheet 5 . The cover sheet 4 and the inner cover sheet 5 are sheets that are bonded together to form a substantially hourglass-shaped (gourd-shaped) outer surface of the diaper 1, except for the end on the front body region 1F side and the end on the back body region 1R side. are the same shape and approximately the same size. When worn by the wearer, the cover sheet 4 is laminated on the non-skin surface side of the wearer, and the inner cover sheet 5 is laminated on the skin surface side of the wearer. Between the cover sheet 4 and the inner cover sheet 5 are provided elastic members for forming the waist gather 3R, the belly gather 12 and the leg gathers 3LF, 3LR. In this embodiment, linear rubber is used as the stretchable member. In addition, as the elastic member, instead of the linear rubber, an elastic member such as a belt-shaped rubber can be appropriately selected.

The cover sheet 4 and the inner cover sheet 5 can be made of a nonwoven fabric made of a liquid-impermeable thermoplastic resin, for example, to suppress leakage of exudates. Here, examples of the liquid-impermeable thermoplastic resin include polyethylene (PE), polypropylene (PP), and the like. Hereinafter, the absorbent body 8 and the configuration obtained by combining the back sheet 6, the top sheet 9, and the side sheets 10L, 10R to the absorbent body 8 may be referred to as an inner body, and as a concept corresponding to the inner body, a linear rubber cover is arranged. The sheet 4 and the inner cover sheet 5 are collectively described as an exterior body (an example of an "exterior body" in the present disclosure).

The diaper 1 has a backsheet 6 , an absorber 8 , and a topsheet 9 laminated in this order on the wearer's side surface of a cover sheet 4 and an inner cover sheet 5 . The back sheet 6 is a substantially rectangular sheet having a length extending from the wearer's front body through the crotch to the back body in the longitudinal direction and having a predetermined width in the width direction perpendicular to the longitudinal direction. Both the absorber 8 and the top sheet 9 are sheet-shaped members having an approximately rectangular appearance similar to the back sheet 6 , and are sequentially stacked on the back sheet 6 with the longitudinal direction aligned with the longitudinal direction of the back sheet 6 . The backsheet 6 is a sheet formed of a liquid-impermeable thermoplastic resin to suppress leakage of exudates. In addition, minute holes are provided in the back sheet 6 . The holes are both liquid-proof and air-permeable. The hole is provided, for example, in a region overlapping with the absorber 8 . In addition, the top sheet 9 is a sheet-shaped member arranged on the wearer's skin side so as to cover the water-absorbing surface of the absorber 8 . This top sheet 9 has liquid permeability in a part or the whole. Therefore, when the diaper 1 is worn, liquid discharged from the wearer penetrates into the absorber 8 through the top sheet 9 that may come into contact with the wearer's skin, and is absorbed there. Examples of the liquid-permeable sheet include woven fabrics, nonwoven fabrics, and porous films. In addition, the top sheet 9 may have hydrophilicity.

The absorbent body 8 has an absorbent core 8c and the core wrapping sheet 7 which wraps the absorbent core 8c. The absorbent core 8c has a substantially hourglass shape having a constricted portion. The absorbent core 8c has a granular absorbent resin (absorbent polymer) such as SAP (Super Absorbent Polymer), which is a hydrophilic polymer with a cross-linked structure capable of absorbing and retaining water, held on pulp fibers. , short fibers of cellulosic fibers such as rayon fibers or cotton fibers, and short fibers of synthetic fibers such as polyethylene, polypropylene, or polyethylene terephthalate that have been hydrophilized. When the absorbent core 8c absorbs the liquid discharged from the wearer, it swells the absorbent resin held in the gaps in the short fibers to hold the liquid in the short fibers. In this embodiment, the absorbent core 8c has a substantially hourglass shape narrowed in the vicinity of the central part. The absorbent core 8c can take an appropriate shape according to the purpose. As the shape of the absorbent core 8c, a rectangular shape, an oval shape, and other various shapes are mentioned, for example. In addition, in this embodiment, although the absorbent core 8c is formed with one pad, the absorbent core 8c may be formed with a some pad.

The core wrapping sheet 7 is a thin liquid-permeable sheet, and by wrapping the absorbent core 8c with the core wrapping sheet 7, SAP of the above-mentioned absorbent core 8c is less likely to be mixed into other structures. Moreover, the distortion of the absorbent core 8c is suppressed. The core wrap sheet 7 can be formed using pulp fibers, and paper towels can be used as an example. The core wrapping sheet 7 may be a single sheet, but it may also be composed of an upper side sheet disposed on the wearer's skin side and a lower side disposed on the non-skin side of the wearer and wrapped around the side of the absorbent core 8c and the skin side. These two sheets constitute the sheet. When the core wrapping sheet 7 is composed of two sheets, it is also possible to wrap the widthwise ends of the upper side sheet with other sheets (for example, side sheets 10L, 10R, back sheet 6, and top sheet 9 described later). living structure. In addition, since the absorber 8 is surrounded by the back sheet 6 and the top sheet 9, since the loss of shape can also be suppressed by these sheets, it is also possible not to provide the core wrapping sheet 7.

The backsheet 6, the absorber 8, and the topsheet 9 all extend from the front body region 1F to the back body region 1R. Thus, if the back sheet 6, the absorber 8, and the top sheet 9 are laminated to cover the wearer's private parts (inseam), the respective longitudinal ends of the back sheet 6, the absorber 8, and the top sheet 9 will be positioned at The state of the wearer's ventral and dorsal sides. That is, the wearer's private parts are in a state covered by the absorber 8 from the wearer's abdominal side to the back side. Therefore, regardless of whether the wearer discharges the liquid out of the body in whichever posture the wearer turns his belly down or his back, the discharged liquid comes into contact with the absorber 8 via the top sheet 9 .

Moreover, the diaper 1 has elongated strip-shaped side panel 10L, 10R for forming the above-mentioned three-dimensional gathers 3BL, 3BR. The side sheets 10L and 10R are provided on the long sides of the top sheet 9 . Further, linear rubbers 10L1 and 10R1 are adhered to the side sheets 10L and 10R in a state of being stretched along the longitudinal direction. Thus, if the edge 4F4 which becomes the left edge of the front body region 1F of the cover sheet 4 and the edge 4R4 which becomes the left edge of the back body region 1R are joined to each other, and the right side of the front body region 1F of the cover sheet 4 becomes The edge 4F5 of the edge and the edge 4R5 which becomes the right side edge of the back body area 1R are mutually joined to become the diaper 1 of the completed state shown in FIG. The contraction force pulls in the longitudinal direction and rises from the top sheet 9 along the folding lines 10L2 and 10R2. As a result, three-dimensional gathers 3BL and 3BR are formed to prevent fluid from flowing out from the left lower limb opening 2L and the right lower limb opening 2R.

Here, regarding the side panels 10L, 10R, when the three-dimensional gathers 3BL, 3BR are formed, the intervals in the width direction between the respective rising lines of the three-dimensional gathers 3BL, 3BR are set to the extent that the inner pad can enter. In addition, the joining method of the edge 4F4 and the edge 4R4, and the edge 4F5 and the edge 4R5 is not specifically limited, For example, heat sealing, high-frequency sealing, ultrasonic sealing, etc. can be performed.

Furthermore, the diaper 1 has an end sheet 11F laminated on the wearer's side in the front body region 1F of the cover sheet 4 with the back sheet 6, the absorber 8, the top sheet 9, and the side sheets 10L and 10R interposed therebetween, and the cover sheet 4 The end sheet 11R is laminated on the wearer's side in the back body region 1R. The end sheets 11F and 11R are elongated sheets that overlap the cover sheet 4 and the inner cover sheet 5 at one end side in the longitudinal direction of the top sheet 9 . The end sheets 11F and 11R are non-woven fabrics that are impermeable to water, and reinforce the cover sheet 4 and the inner cover sheet 5 mainly at the waist portion of the diaper 1 . In addition, an adhesive is applied to the end sheets 11F and 11R, respectively, and is bonded to the inner cover sheet 5 by the adhesive. The end sheets 11F, 11R are laminated on the side of the skin side of the laminate formed by the back sheet 6, the absorber 8, the top sheet 9, and the side sheets 10L, 10R, so as to prevent the end of the laminate from directly contacting the skin surface and wear it. Those who bring a sense of disobedience.

Fig. 3 is an example of a diagram schematically showing a state in which the diaper 1 according to Embodiment 1 is unfolded and stretched. Part (A) of FIG. 3 schematically shows the internal structure when the diaper 1 in the unfolded and stretched state is viewed from the left side. Part (B) of FIG. 3 is a plan view of the diaper 1 in an unfolded and stretched state.

As shown in Fig. 3, the linear rubber 4F3 (an example of the "first elastic member" of the present disclosure) forming the leg gathers 3LF is formed along the right lower limb where the wearer's leg enters when the diaper 1 is assembled. The opening 2R and the left lower limb opening 2L are provided in such a manner as to form edges on the front body region 1F side. The linear rubber 4F3 is bonded to the cover sheet 4 and the inner cover sheet 5 in a stretched state. Further, the linear rubber 4F3 is provided so as to cross in the left-right direction in the crotch region 1B on the front side. In this way, the linear rubber 4F3 overlaps with the absorber 8 in the thickness direction of the diaper 1 at the site|part which provided the linear rubber 4F3 so that it may cross the left-right direction. Moreover, the width direction central part of such a transverse area|region becomes the area|region corresponding to the urethral opening of a wearer when the diaper 1 is worn. In addition, in the region overlapping with the absorber 8 in the thickness direction, the arrangement form of the linear rubber 4F3 is not limited to crossing as shown in FIG. 3 . The extending direction of the linear rubber 4F3 only needs to have a component in the width direction, and it is preferable that the component in the width direction in the extending direction of the linear rubber 4F3 is larger than the component in the longitudinal direction.

On the other hand, the linear rubber 4R3 (an example of the "second elastic member" of the present disclosure) forming the leg gather 3LR is formed along the edge of the rear body region 1R side of the right lower limb opening 2R and the left lower limb opening 2L. mode settings. The linear rubber 4R3 is bonded to the cover sheet 4 and the inner cover sheet 5 in a stretched state. In addition, in the crotch region 1B on the back side, the front end of the linear rubber 4R3 faces the width direction. However, the linear rubber 4R3 is cut at the central portion in the width direction, and the left linear rubber 4R3 and the right linear rubber 4R3 are not connected.

In addition, the inner cover sheet 5 and the absorber 8 are appropriately bonded by an adhesive agent via the back sheet 6 from the front body region 1F to the back body region 1R. However, as shown in FIG. 3 , in the region where the linear rubber 4F3 crosses in the front body region 1F, the inner cover sheet 5 and the absorber 8 are non-adhesive (referred to as a non-adhesive region 15 ). Actually, in the non-adhesive area 15, the inner cover sheet 5 and the back sheet 6 are not bonded. In the present embodiment, the non-adhesive region 15 is provided over the entire overlapping region of the crotch region 1B where the linear rubber 4F3 and the absorber 8 overlap.

The cover sheet 4 is folded back at one end side at the folded-back lines 4FF and 4RF shown in FIG. 2 . The aforementioned waist gathers 3R are obtained by bonding linear rubber (linear rubber) 4F1 to the front body region of the cover sheet 4 in an extended state and bonding linear rubber (linear rubber) 4F1 to the rear body region of the cover sheet 4 in an extended state. Rubber (linear rubber) 4R1 and formed. The linear rubbers 4F1 and 4F2 are provided in order from the folding line 4FF side along the folding line 4FF that forms the upper edge of the front body region 1F when folded back. Similarly, the belly gathers 12 (refer to FIG. 1 ) are formed by bonding a linear rubber 4F2 to the front body region 1F of the cover sheet 4 in a stretched state and bonding a thread to the rear body region 1R of the cover sheet 4 in a stretched state. Formed like rubber 4R2. The linear rubbers 4R1, 4R2 are also the same as the linear rubbers 4F1, 4F2, along the folded line 4RF that forms the upper edge of the back body region 1R if folded back, from the folded line 4RF side, the linear rubber 4R1, the line Set in the order of rubber-like 4R2.

Therefore, linear rubber|gum 4F1, 4F2 is provided in the cover sheet 4 so that the longitudinal direction which becomes an expansion-contraction direction may become the left-right direction of the diaper 1. Moreover, linear rubber|gum 4R1, 4R2 is provided in the cover sheet 4 so that the longitudinal direction which becomes an expansion-contraction direction may become the left-right direction of the diaper 1. Thus, when the edge 4F4 and the edge 4R4 are joined to each other and the edge 4F5 and the edge 4R5 are joined to each other, the linear rubbers 4F1, 4F2 and the linear rubbers 4R1, 4R2 form a substantially annular ring that goes around along the trunk opening 2T. The telescopic member functions to contract the trunk opening 2T in the direction around the trunk. That is, the linear rubbers 4F1 and 4F2 and the linear rubbers 4R1 and 4R2 exert contraction force to make the diaper 1 adhere to the wearer, and prevent a gap from being formed between the diaper 1 and the wearer's abdomen. The linear rubber 4F2 and the linear rubber 4R2 overlap the absorber 8 at a part on the crotch region 1B side.

The linear rubbers 4F1 and 4R1 are provided so as to extend in the left-right direction along portions serving as upper edges of the front body region 1F and the rear body region 1R shown in FIG. 1 . The linear rubbers 4F2 and 4R2 are provided in parallel at predetermined intervals. The linear rubbers 4F1 and 4R1 fasten the waist circumference of the wearer more strongly than the linear rubbers 4F2 and 4R2 in a state where the diaper 1 is worn. The linear rubbers 4F1 and 4R1 have the functions of keeping the diaper 1 in close contact with the wearer, preventing shifting of the wearing position, and preventing discharge from leaking from the abdomen and the back. The linear rubbers 4F2 and 4R2 relieve the pressure feeling on the wearer due to the contraction force of the linear rubbers 4F1 and 4R1.

The cover sheet 4 is folded back at the folding lines 4FF and 4RF to extend to the arrangement area of the linear rubber 4F1 and the linear rubber 4R1 , and the area for the arrangement of the linear rubber 4F1 and the linear rubber 4R1 is reinforced by the folded back portion. The end pieces 11F, 11R (refer to FIG. 2 ) are arranged in the arrangement area of the linear rubber 4F2 and the linear rubber 4R2 where the cover piece 4 is not extended after being folded back at the folding line 4FF, 4RF. The allocation area of rubber 4R2 is strengthened.

In addition, in the present application, the overlapping state of the sheets is not limited to the overlapping state in which the overlapping sheets are in full contact with each other, and is a concept including an overlapping state in which a part of the sheets overlap each other. For example, a part of the end sheet 11F on one end side in the longitudinal direction of the back sheet 6 overlaps with a part of the cover sheet 4 in a contact state. In addition to the back sheet 6 and the top sheet 9 sandwiching the absorber 8, the diaper 1 also has a cover sheet 4, end sheets 11F, 11R, inner cover sheet 5, side sheets 10L, 10R stacked and formed, so it can be said to have A laminate obtained by stacking these plural sheets.

Fig. 4 is a plan view showing the absorber 8, part of the linear rubbers 4F3 and 4R3, and the linear rubber 4F7 extracted from the diaper 1 . In addition, in FIG. 4, the non-adhesion area|region 15 is painted and shown in figure. In the non-adhesive region 15 where the linear rubber 4F3 crosses in the crotch region 1B on the front body side (abdomen side) as shown in FIG. 4 , the inner cover sheet 5 and the absorber 8 are not bonded. Thereby, the absorber 8 is pressed against the skin without shrinking in the width direction due to the shrinkage force of the linear rubber 4F3 provided between the cover sheet 4 and the inner cover sheet 5 .

Here, the non-adhesive area 15 includes the area corresponding to the urethral meatus. The area corresponding to the urethral opening is the area where the wearer's urethral opening is located when the diaper 1 is worn, and the central portion in the width direction of the non-adhesive area 15 corresponds to this. By providing the non-adhesive region 15 , in the region corresponding to the urethral opening, the absorber 8 is more likely to swell toward the non-skin surface side than the region in the front and rear in the longitudinal direction. If the expansion of the absorbent body is completely restricted in the region corresponding to the urethral opening, the absorption rate of urine by the absorbent body will decrease. A decrease in the absorption rate of the absorbent body may cause urine leakage. Therefore, in the diaper 1 according to this embodiment, the absorber 8 can be expanded by providing the non-adhesive region 15 in the area corresponding to the urethral opening, and the skin of the non-adhesive region 15 can be stretched by the contraction force of the linear rubber 4F3. The absorbent body 8 on the surface side is raised toward the skin surface side to abut the absorbent body 8 against the urethral opening, so that the absorbent body 8 easily sucks urine. In addition, when the wearer is a male, by pushing the absorber 8 toward the skin side to cover the male genitals, the absorber 8 can easily absorb urine discharged from the tip of the male genitals. In the diaper 1 according to the present embodiment, since the absorber 8 easily absorbs urine, leakage of urine to the outside can be suppressed.

In addition, in the diaper, the area corresponding to the urethral opening is the area that most absorbs and retains the moisture of urine, and tends to sag downward due to the weight of urine. In this embodiment, the area corresponding to the urethral opening is raised from the non-skin side to the ventral side by the linear rubber 4F3, and the wearer's skin and the diaper are prevented from being separated more than necessary (excessively). In addition, the diaper 1 uses the linear rubber 4F3 to limit excessive expansion of the absorbent body 8 in the area corresponding to the urethral opening, that is, to reduce the absorption rate of urine in the area corresponding to the urethral opening, and to move the urine outside the area corresponding to the urethral opening. Makes it possible to absorb and hold urine in the entire area of the absorbent body 8 . In addition, when the absorbent body 8 sags due to excrement, the diaper 1 allows the expansion and sagging of the absorbent body 8 in the area corresponding to the urethral opening to prevent excessive pressure on the urethral opening, and prevents the urethral opening by the contraction force of the linear rubber 4F3. The area corresponding to the mouth is kept away from the urethral opening to prevent leakage. The diaper 1 according to this embodiment can suppress urine leakage to the outside.

In addition, the absorber 8 is bonded to the exterior body before and after the non-adhesive region 15 . Specifically, the backsheet 6 and the absorber 8 are bonded, and the backsheet 6 and the inner cover sheet 5 are bonded in the front and rear of the non-bonding region 15 in the longitudinal direction of the diaper 1 . In the diaper 1, since the absorber 8 is bonded to the exterior body before and after the non-adhesive region 15, even if the absorber 8 on the skin surface side outside the non-adhered region 15 absorbs urine, the absorption of this part can be suppressed. Body 8 droops.

In addition, the diaper 1 suppresses excessive separation of the absorber 8 from the urethral opening even after urine is absorbed by the linear rubber 4F3. If the absorber is separated from the urethral opening, urine may not reach the absorber. Also, if the absorber becomes heavy due to urine and sags, and the wearer urinates without the three-dimensional gathers being in contact with the skin, lateral leakage of urine may also occur. In the diaper 1 according to the present embodiment, since the excessive expansion of the absorber 8 is restricted by the linear rubber 4F3, the absorber 8 on the skin side of the non-adhesive region 15, which absorbs a relatively small amount of urine, can be made of linear rubber. 4F3 to push up toward the urethral opening to prevent the absorber 8 from leaving the urethral opening after urine is absorbed.

In addition, by providing the non-adhesive region 15 in the diaper 1, it is possible to prevent the contraction force of the linear rubber 4F3 from being applied to the absorber 8 and to suppress the deformation of the absorber 8, so that the absorber 8 in a flat state without wrinkles or the like can be placed against the wearer. contact with the urethral opening. Therefore, the diaper 1 can immediately absorb the urine excreted from the wearer, and can prevent the urine excreted from the wearer from leaking to the outside of the diaper 1 . In addition, when the inner pad is used in combination, since the inner pad is pressed against the urethral opening by the absorber 8 without wrinkles, the leakage of urine to the outside of the diaper 1 can be similarly prevented.

In the present embodiment, linear rubber 4R3 for forming leg gathers is used as an elastic member that pulls the absorber 8 outward in the width direction. When the wearer's legs are passed through the left and right leg openings 2L, 2R, the linear rubber 4R3 is pulled widthwise outward, whereby the linear rubber 4R3 can pull the absorber 8 further widthwise outward.

In addition, in this embodiment, although the linear rubber 4R3 for leg gather formation was used as the elastic member which pulls the absorber 8 outward in the width direction, it is not limited to this. For example, an elastic member that pulls the absorber 8 outward in the width direction may be directly bonded to the absorber 8, or a linear rubber elastic member for forming leg gathers may be provided on the exterior body. Here, when the outer body is provided with a stretchable member such as linear rubber 4R3 that pulls the absorber 8 outward in the width direction, the inner cover sheet 5 and the backsheet 6 are bonded in the stretched region of the stretchable member. In a bonded state, the back sheet 6 and the absorber 8 are brought into a bonded state. Thereby, the absorber 8 can be pulled by the elastic force of an elastic member.

In addition, the widthwise inner end portion of the linear rubber 4R3 overlaps with the absorber 8 when viewed in the thickness direction, and the expansion and contraction direction has a widthwise component. Accordingly, the linear rubber 4R3 can more reliably pull the absorber 8 outward in the width direction.

Moreover, the inner cover sheet 5 and the absorber 8 are bonded between a pair of linear rubber|gum 4R3. Here, between the pair of linear rubbers 4R3 is an anus corresponding region 30 shown in FIG. 4 . By bonding the absorber 8 and the exterior body, the bending rigidity between the pair of linear rubbers 4R3 increases, and the cross-sectional shape becomes less likely to be W-shaped. On the other hand, since the non-adhesive region 15 is provided in the abdominal urethral opening corresponding region, the absorber 8 is easier to bend than the anus corresponding region 30 . In addition, in order to make the absorber 8 in the area corresponding to the urethra orifice easier to bend than the area 30 corresponding to the anus, the bonding portion between the absorber 8 and the inner cover sheet 5 may be narrower in the area corresponding to the urethra orifice than in the area 30 corresponding to the anus. Alternatively, the bonding portion is gradually narrowed toward the ventral side.

In addition, the diaper 1 is closely attached to the waist by the linear rubbers 4F1 and 4F2 on the abdominal side and is closely attached to the leg circumference by the linear rubber 4F3, whereby the anus vicinity of the wearer on the back side can be lifted from the wearer. Instead, a space is formed near the anus and holds feces in this space. Thereby, the diaper 1 can also suppress the fall of a feeling of wearing. In addition, by providing the non-adhesive region 15, the contraction force of the linear rubber 4F3 does not function to deform the absorber 8 into a W shape by shrinking the absorber 8 in the left-right direction, but to move the absorber 8 toward the The skin side is pushed up to improve the adhesiveness between the absorber and the skin in the area corresponding to the urethral opening.

In addition, the ventral linear rubbers 4F1, 4F2 and linear rubber 4F3, which are provided on the outer body in an extended state along the trunk opening 2T to expand and contract in the width direction, have different colors (for example, red, colored blue). In the diaper 1 according to the present embodiment, by using the linear rubbers 4F1 and 4F2 to define the outline of the waist on the abdominal side and using the linear rubber 4F3 to define the outline of the leg circumference on the abdominal side, it is possible to change the shape significantly between the abdominal side and the back side. impression. Thereby, the diaper 1 can make front-back distinction easier.

In addition, in this embodiment, the non-adhesive area 15 is provided in the area where the linear rubber 4F3 and the absorber 8 overlap. Assuming that the non-adhesive region 15 is not provided and the absorber 8 and the inner cover sheet 5 are bonded via the backsheet 6 in this region, the shrinkage force of the linear rubber 4F3 acts to shrink the absorber 8 in the width direction, Therefore, the exterior body will be caught in the irregularities generated in the absorber 8, and the linear rubber 4F3 may not be visually recognized from the outside at this portion. In the present embodiment, since the non-adhesive region 15 is provided, the linear rubber 4F3 can be visually confirmed from the outside.

In this embodiment, as shown in FIG. 4 , the non-adhesive region 15 crosses the part of the crotch region 1B than the linear rubber 4F3 (hereinafter, this part may be referred to as "the crossing part of the linear rubber 4F3"). Extends to the front body region 1F side and the rear body region 1R side. Moreover, as shown in FIG. 4, linear rubber|gum 4F3 has the component of the longitudinal direction of the diaper 1 in the width direction outer side of the diaper 1 rather than the absorber 8. Here, the longitudinal component is a component extending and contracting along the longitudinal direction of the diaper 1, and the linear rubber 4F3 has a longitudinal component even if the linear rubber 4F3 extends obliquely with respect to the longitudinal direction.

The non-adhesive region 15 is formed on the front body region 1F side including the extended region of the linear rubber 4F3, and has a component stretching and contracting in the longitudinal direction of the diaper 1 on the outside in the width direction of the crossing portion of the linear rubber 4F3. Therefore, the outer body (cover sheet 4 and inner cover sheet 5) in the non-adhesive region 15 is pulled to the front body region 1F side by the linear rubber 4F3, and the inner body including the absorber 8 is also pulled to the front body region 1F by the outer body. side lift. In the diaper 1 having this structure, the absorber 8 on the skin surface side of the non-adhesive region 15 is pulled up to the front body region 1F side, and the absorber 8 can be prevented from separating from the wearer's skin surface. In addition, if the non-adhesive region 15 is formed on the front body region 1F side than the extension region of the linear rubber 4F3, the inner body including the absorber 8 can also be pulled by the linear rubber 4F3 on the front body region 1F side. Lift to the side of the torso area 1F.

Here, the case where the wearer of the diaper 1 is a woman is demonstrated. It is designed so that when a woman wears the diaper 1, the opening of the urethra is approximately located at the crossing portion of the linear rubber 4F3. Thus, the crossing portion of the linear rubber 4F3 includes a region corresponding to the urethral opening of the female wearer. As mentioned above, by using the linear rubber 4F3 to lift the outer body and the inner body including the absorbent body 8 on the front body region 1F side on the non-adhesive area 15, the absorbent body 8 is brought close to the female urethral opening, The discharged urine tends to infiltrate into the absorber 8 . Thereby, the diaper 1 can suppress the leakage of urine.

Next, a case where the wearer of the diaper 1 is a male will be described. It is designed so that when a man wears the diaper 1 , the crossing portion of the linear rubber 4F3 is located closer to the crotch side than the position of the penis (male sex organ) of the man. In other words, the male penis is located closer to the front body region 1F than the crossing portion of the linear rubber 4F3. In this way, the crossing portion of the linear rubber 4F3 is located closer to the crotch side than the region corresponding to the penis. The diaper 1 lifts the outer body and the inner body including the absorbent body 8 on the front body region 1F side on the non-adhesive region 15 by using the linear rubber 4F3, so that the absorbent body 8 can be abutted against the back side of the testicles, and it can be aligned with the penis. The area that forms the space that holds the penis. Since a male wearer urinates through the urethral opening of the penis, the diaper 1 can control the direction of urination and suppress urine leakage by holding the penis.

In addition, it is designed so that, when a man wears the diaper 1, the testicle is approximately located at the crossing portion of the linear rubber 4F3. Thus, the crossing portion of the linear rubber 4F3 includes an area corresponding to the testicle of a male wearer. The absorber 8 also expands along with the expansion of the testis, but the testis can be held by lifting the absorber 8 with the linear rubber 4F3. In addition, even if the position of the testis is shifted or the position of the testis relative to the diaper 1 is different depending on the wearer, by providing the non-adhesive region 15, the relative position of the crossing portion of the linear rubber 4F3 with respect to the testis can be moved. The testicles can be held by lifting the absorber 8 where the testicles are located by the linear rubber 4F3.

In addition, since the diaper 1 is provided with the non-adhesive region 15, shrinkage of the absorber 8 at the crossing portion of the linear rubber 4F3 can be suppressed. If the absorber shrinks and collides with the wearer's skin, it will give the wearer a sense of incongruity and the feeling of wearing will decrease. The diaper 1 which concerns on this embodiment can suppress the fall of wearing feeling by suppressing the contraction of the absorber 8. In addition, if the absorbent body shrinks after absorbing urine, the pulp may collapse. The diaper 1 according to this embodiment can suppress the loss of shape of the absorber 8 by suppressing the shrinkage of the absorber 8 .

Moreover, the diaper 1 is equipped with the linear rubber 4F2 (an example of "the 3rd elastic member" of this indication) arrange|positioned in the front body area|region 1F side rather than the area|region corresponding to a wearer's penis. As described above, the linear rubber 4F2 expands and contracts in the width direction of the diaper 1, and overlaps the absorber 8 at a part on the crotch region 1B side. Therefore, the linear rubber 4F2 pulls the absorber 8 in the width direction in the wearing state of the diaper 1 . Specifically, the linear rubber 4F2 pulls the end portion of the absorber 8 on the front body region 1F side in the width direction in the wearing state of the diaper 1 . Thereby, the front body region 1F side of the absorber 8 forms the front side edge of the space which holds a male penis. In addition, in the present embodiment, the absorber 8 is pulled in the width direction by the linear rubber 4F2 forming the belly gathers 12 (see FIG. 1 ), but a separate linear rubber may be provided. The linear rubber may be directly bonded to the absorber 8, or the linear rubber may be bonded to the exterior body.

In addition, the non-adhesive region 15 is formed on the side of the front body region 1F including the extension region of the linear rubber 4F3, and the linear rubber 4F3 crosses the absorber 8 on the outside in the width direction, and has the function of stretching and contracting in the longitudinal direction of the diaper 1. ingredients. Therefore, the outer body (the cover sheet 4 and the inner cover sheet 5 ) in the non-bonding region 15 is pulled by the linear rubber 4F3 toward the front body region 1F. The diaper 1 uses the linear rubber 4F3 to pull the outer body forward, thereby pulling the absorber 8 on the rear side than the non-adhesive region 15 to the front, so that the front and rear sides of the absorber 8 can be adjusted in the wearing state. The direction of the back side is inclined downward (non-skin side). The diaper 1 can relatively separate the absorber 8 from the wearer's skin in the anus-corresponding region 30 on the rear side of the central part by inclining the absorber 8 downward relative to the central part in the longitudinal direction. Thus, the diaper 1 can form a space between the anus corresponding region 30 and the wearer's skin. The diaper 1 can improve the wearing feeling at the time of defecation by accommodating feces in this space.

<Embodiment 2>

Next, the diaper 1 according to Embodiment 2 will be described. FIG. 5 is an example of an exploded perspective view of a diaper according to Embodiment 2. FIG. In addition, the same reference numerals are assigned to the same components as those of the first embodiment described above, and description thereof will be omitted.

As shown in FIG. 5 , between the back sheet 6 and the core wrap sheet 7 , a linear rubber 4F7 is provided in the center in the width direction in a stretched state in the longitudinal direction from the front body region 1F to the crotch region 1B. The linear rubber 4F7 adheres to the back sheet 6 and adheres to the inner cover sheet 5 and the cover sheet 4 via the back sheet 6 . The linear rubber 4F7 exerts a force to shrink the inner cover sheet 5 and the cover sheet 4 in the longitudinal direction. In addition, the region where the linear rubber 4F7 is provided is preferably a region where the absorber 8 and the inner cover sheet 5 are not bonded, but may be a region where the absorber 8 and the inner cover sheet 5 are bonded. In addition, the linear rubber 4F7 may be provided between the cover sheet 4 and the inner cover sheet 5 .

In addition, the linear rubber cover sheet 13 (extensible member cover sheet) is arranged on the skin surface side of the linear rubber 4F7. The linear rubber cover sheet 13 covers the linear rubber 4F7 from the skin side and is bonded to the back sheet 6 . The linear rubber cover sheet 13 is arranged between the linear rubber 4F7 and the absorber 8 . In addition, the linear rubber cover sheet 13 is not bonded to the core wrap sheet 7 of the absorber 8 as a whole. The linear rubber cover sheet 13 is arranged between the absorber 8 and the back sheet 6 , adheres to the back sheet 6 , and is partially non-adhered to the core wrap sheet 7 of the absorber 8 . Thereby, the elastic force (contraction force) of the linear rubber 4F7 can be prevented from acting excessively on the absorber 8, and the absorber 8 can be prevented from deforming excessively. In addition, when using a strip-shaped elastic member instead of the linear rubber 4F7, the elastic member and the core wrap sheet 7 can be partially non-adhered without providing the linear rubber cover sheet 13 . In addition, in this embodiment, the linear rubber cover sheet 13 is formed in the same length as the back sheet 6 . In addition, the linear rubber cover sheet 13 may be formed to have a length corresponding to the extending region of the linear rubber 4F7, or may be formed to be longer than the extending region of the linear rubber 4F7 and shorter than the back sheet 6. In addition, a part of the linear rubber cover sheet 13 is not bonded to the absorber 8 . The linear rubber cover sheet 13 may not be bonded to the absorber 8 as a whole.

Fig. 6 is an example of a diagram schematically showing a state in which the diaper 1 according to Embodiment 2 is unfolded and stretched. Part (A) of FIG. 6 schematically shows the internal structure when the diaper 1 in the unfolded and stretched state is viewed from the left side. Part (B) of FIG. 6 is a plan view of the diaper 1 in an unfolded and stretched state.

As shown in FIG. 6 , the linear rubber 4F7 is stretched in the longitudinal direction from the front body region 1F to the crotch region 1B, and is provided in the widthwise central portion between the back sheet 6 and the core wrap sheet 7 . Actually, the linear rubber 4F7 is provided between the back sheet 6 and the linear rubber cover sheet 13 . Moreover, the rear side rather than the linear rubber 4F7 corresponds to the wearer's anus when the wearer wears the diaper 1 . In addition, the absorber 8 is pressed linearly so as to surround the linear rubber 4F7 , and is shown as a line 14 in FIG. 6 . The end portion of the thread 14 on the crotch region 1B side is provided in the width direction. In addition, the thread 14 is bent outward in the width direction at an end portion on the front body region 1F side. In addition, such pressing of the absorber 8 is realized by embossing with a roll, for example.

Next, the thread 14 formed in the absorber 8 is demonstrated using FIGS. 7-8. Fig. 8 is a cross-sectional view when the diaper 1 is cut along the line VIII-VIII of part (B) of Fig. 6 in the width direction.

As shown in FIG. 7, the wire 14 has four grooves. The four grooves are composed of grooves 14AL, 14AR, and grooves 14BL, 14BR. The grooves 14AL and 14AR are formed in the absorber 8 and extend from the crotch region 1B toward the front end of the body region 1F from the center of the diaper 1 in the width direction toward the outside in a region corresponding to the wearer's groin. groove. The grooves 14AL and 14AR are squeeze grooves formed by squeezing the absorber 8 . In addition, the grooves 14AL and 14AR may be formed by pressing only the absorbent core 8c, or may be formed by pressing the absorber 8 including the core wrap sheet 7 . In this embodiment, the grooves 14AL and 14AR are formed by pressing the core wrap sheet 7 and the absorbent core 8c from the skin surface side. The absorber 8 is bent along the wearer's groin by forming the grooves 14AL, 14AR.

In addition, the non-adhesive region 15 is provided so as to include a region overlapping with the grooves 14AL and 14AR in a planar view of the region provided with the grooves 14AL and 14AR. Assuming that the non-adhesive region 15 is formed without including the region overlapping with the grooves 14AL, 14AR, and the absorber 8 and the inner cover sheet 5 are bonded in this region, the exterior body is expanded and becomes in a state of colliding with the skin side. As a result, the state of the exterior body is transmitted to the absorber, and a force that approaches the absorber from a state bent along the groin to a flat state acts on the absorber. On the other hand, the diaper 1 which concerns on this embodiment is comprised as mentioned above, and the absorber 8 in the state bent along a groin part can maintain a bent state, and can abut against a skin surface side. Thereby, the diaper 1 can improve the adhesiveness of the absorber 8 with respect to the wearer's skin.

Moreover, as shown in FIG. 7, the non-adhesion area|region 15 extends in the width direction of the diaper 1, and has a substantially rectangular shape. When the diaper 1 is worn and the exterior body is pulled in the left-right direction, the exterior body pushes the absorber 8 toward the skin surface, and the absorber 8 can be brought into contact with the wearer's skin surface. Thereby, the diaper 1 can improve the adhesiveness of the absorber 8 with respect to the wearer's skin.

In addition, when the diaper 1 is viewed planarly as shown in FIG. 7 , the diaper 1 includes linear rubber 4F3 bonded to the inner cover sheet 5 and the cover sheet 4 in a stretched state in a region overlapping with the non-adhesive region 15 . Moreover, as shown in FIG. 6, the end part of the linear rubber 4F3 is arrange|positioned at the end part of the width direction of the left lower limb opening part 2L, and the right lower limb opening part 2R. By inserting the legs into the left and right leg openings 2L, 2R provided in the exterior body, the exterior body is pulled widthwise outward, and the linear rubber 4F3 is also pulled widthwise outward. Thus, in the region where the linear rubber 4F3 extends in the width direction across the crotch region 1B, the exterior body is pushed up toward the skin side, but the absorber 8 and the exterior body are not bonded in this region. Non-adhesive area 15. Therefore, the absorber 8 is pushed up by the exterior body so as to approach the skin surface side while maintaining a bent state along the groin portion. In addition, in the present embodiment, the linear rubber 4F3 for forming leg gathers extends in the non-adhesive region 15 and is connected to the left and right, but it may be provided separately in the non-adhesive region 15 and cross the crotch region 1B. The thread rubber and the thread rubber for leg gathers. In addition, the end portion of the linear rubber 4F3 may be bonded to the exterior body, and the thread may be bonded to another sheet arranged between the exterior body and the back sheet in the non-adhesive region 15 at the center in the width direction. shaped rubber. Even if comprised in this way, if a backsheet and another sheet|seat are non-adhered in the non-adhesive area|region 15, the diaper 1 can acquire the effect mentioned above.

Next, grooves 14BL and 14BR will be described. The grooves 14BL and 14BR are a pair of left and right grooves formed in the absorber 8 and extending in the longitudinal direction in a region corresponding to the wearer's urethral opening. Grooves 14BL and 14BR are squeeze grooves formed by squeezing absorber 8 . In addition, the grooves 14BL and 14BR may be formed by pressing only the absorbent core 8c, or may be formed by pressing the absorber 8 including the core wrap sheet 7 . In this embodiment, the grooves 14BL and 14BR are formed by pressing the core wrap sheet 7 and the absorbent core 8c from the skin surface side. Since the absorber 8 is formed with the grooves 14BL and 14BR, the absorber 8 between the grooves is raised toward the urethral opening side. Thereby, since the diaper 1 can abut the absorber 8 against the urethral opening, the adhesiveness of the absorber 8 to the wearer's skin can be improved.

In addition, the linear rubber 4F3 is arranged so as to include a region overlapping with the front body region 1F side of the grooves 14BL, 14BR when viewed in plan. With this structure, the effect of making the absorber 8 abut against the wearer's skin side in a bent state by the linear rubber 4F3 is enhanced. This is because the non-adhesive region 15 is provided in the area where the linear rubber 4F3 and the absorber 8 overlap, so that the absorber 8 is not deformed due to the shrinkage of the linear rubber 4F3 and can be bent through the grooves 14BL and 14BR. The absorbent body 8 in the shape of abuts against the skin side. In addition, in order to achieve this effect, it is preferable that the linear rubber 4F3 is pulled in the left-right direction while the legs are inserted through the left and right lower limb openings 2L, 2R, thereby pressing the absorber 8 against the skin. Depend on. Therefore, the linear rubber 4F3 is suitably the linear rubber for leg gather formation which arrange|positions the edge part at the edge part of the width direction of the diaper 1. As shown in FIG. In addition, when the linear rubber 4F3 for forming leg gathers overlaps with the grooves 14AL and 14AR when viewed in the thickness direction, it is suitable for folding the absorbent body 8 bent along the groin by the shrinkage force of the linear rubber 4F3. against the wearer's skin side. In addition, if the linear rubber 4F3 for forming leg gathers overlaps with the grooves 14BL and 14BR when viewed in the thickness direction, it is suitable for abutting the absorber 8 to the urethral opening or placing the inner pad on the top sheet 9. (Urinary pad) against the urethral opening. In addition, the diaper 1 may have a configuration in which the linear rubber 4F3 overlaps the grooves 14AL and 14AR, and the linear rubber 4F3 does not overlap the grooves 14BL and 14BR, thereby being suitable for folding the absorbent body 8 along the groin. The linear rubber 4F3 abuts against the wearer's skin side due to the contraction force of the linear rubber 4F3. In addition, the diaper 1 may also be configured in such a way that the linear rubber 4F3 does not overlap the grooves 14AL, 14AR, but the linear rubber 4F3 overlaps the grooves 14BL, 14BR. When 14BL and 14BR are overlapped, it is suitable for abutting the absorber 8 against the urethral opening or for abutting the inner pad (urinary pad) arranged on the top sheet 9 against the urethral opening. In addition, like the present embodiment, the diaper 1 may, of course, have the linear rubber 4F3 overlap the grooves 14AL, 14AR, and the grooves 14BL, 14BR, and adopt both of the above-mentioned two suitable structures.

In addition, the grooves 14AL, 14AR and the grooves 14BL, 14BR are not limited to extrusion grooves. The grooves 14AL, 14AR and the grooves 14BL, 14BR may be thinned grooves formed by reducing the thickness of the pulp in the absorbent core 8c only in the groove forming part, as long as the absorber 8 can be bent starting from the grooves. , through the groove. In addition, by using the grooves 14AL, 14AR and the grooves 14BL, 14BR as squeeze grooves, the groove forming portion can be made highly rigid, and deformation of the groove forming portion can be prevented.

In addition, in this embodiment, the groove 14AL is connected to the groove 14BL, and the groove 14AR is connected to the groove 14BR. Accordingly, the groove 14AL and the groove 14BL can be integrally formed, and the groove 14AR and the groove 14BR can be integrally formed. In addition, the groove 14AL and the groove 14BL may be adjacent to each other with a gap, and the groove 14AR and the groove 14BR may be adjacent to each other with a gap. In addition, when gaps are provided between these grooves, the end of the groove 14BL may not be arranged on the extension line of the groove 14AL, and the end of the groove 14BR may not be arranged on the extension line of the groove 14AR.

In addition, the non-adhesive region 15 includes a region overlapping with the ends of the grooves 14BL, 14BR on the front region 1F side when viewed in plan. By inserting the legs into the left and right leg openings 2L, 2R provided in the exterior body, the exterior body is pulled widthwise outward, and the linear rubber 4F3 is also pulled widthwise outward. Thus, in the region where the linear rubber 4F3 extends in the width direction across the crotch region 1B, the exterior body is pushed up toward the skin side, but the absorber 8 and the exterior body are provided with non-adhesive non-adhesive parts. Area 15. Therefore, the absorber 8 is pushed up by the exterior body so as to approach the urethral orifice side while being held between the grooves 14BL and 14BR in a state of protruding toward the urethral orifice side. Thereby, since the diaper 1 can abut the absorber 8 against the urethral opening, the adhesiveness of the absorber 8 to the wearer's skin can be improved.

The grooves 14BL and 14BR can bend the absorber 8 in a W-shape when cut in the width direction, and can bring the skin side of the absorber 8 into contact with the urethral opening. If the grooves 14BL and 14BR are provided only in the area corresponding to the urethral opening and the portion of the absorbent body 8 other than the groove formation area becomes planar, the groove does not function as a bending mechanism for the absorbent body 8 . Therefore, it is necessary to extend the groove longer than the corresponding area of the urethral opening. Therefore, in the present embodiment, the pair of left and right grooves 14BL, 14BR extending along the longitudinal direction of the diaper 1 extend from the region corresponding to the urethral opening on the ventral side to the region corresponding to the anus 30 on the back side. The anus-corresponding region 30 is a region where the wearer's anus is located when the diaper 1 is worn. In the diaper 1 according to the present embodiment, by extending the grooves 14BL and 14BR to the anus corresponding region 30, the absorber 8 can be bent into a W-shape, thereby improving the adherence of the absorber 8 to the urethral opening of the wearer.

However, if the grooves 14BL, 14BR are formed up to the anus corresponding region 30 and the absorber 8 is bent along the grooves 14BL, 14BR, the absorber 8 may sink into the gluteal cleft (crack) of the wearer's buttocks. If the absorber sinks into the wearer's buttocks, the wearer will feel a sense of pressure, and feces excreted by the wearer will abut against the skin around the wearer's buttocks, reducing the wearing feeling. Then, the diaper 1 which concerns on this embodiment is equipped with a pair of linear rubber|gum 4R3 arrange|positioned at both sides of the width direction of groove 14BL, 14BR. The linear rubber 4R3 pulls the absorber 8 outward in the width direction of the diaper 1 . Thus, the diaper 1 prevents the absorber 8 from being caught in the wearer's gluteal crotch by suppressing the absorber 8 in the anus corresponding region 30 from being bent along the grooves 14BL, 14BR, thereby suppressing a decrease in wearing comfort.

In addition, the inner end portion in the width direction of the linear rubber 4R3 overlaps with the grooves 14BL and 14BR when viewed in the thickness direction. By overlapping the grooves 14BL, 14BR and the linear rubber 4R3, the grooves 14BL, 14BR can be pulled outward in the width direction from directly below the grooves 14BL, 14BR, and the cross-sectional shape of the absorber 8 in the width direction in the anus corresponding region 30 can be prevented from becoming W. Shaped to prevent the absorbent body 8 from sinking into the gluteus groin of the buttocks. By pulling the grooves 14BL, 14BR from directly below, the force acts in the direction of peeling the absorber 8 from the top sheet 9, so that the grooves 14BL, 14BR are easily deformed, that is, the rigidity (hardness) of the squeezed grooves is weakened. , in the anus corresponding region 30, the force of deforming the absorber 8 into a W-shape by the grooves 14BL and 14BR can be weakened.

In addition, the inner end portion in the width direction of the linear rubber 4R3 may be arranged on the outer side of the grooves 14BL and 14BR when viewed in the thickness direction. Contrary to pulling the grooves 14BL, 14BR from directly below, the adhesion between the absorber 8 and the skin-side material (for example, the top sheet 9) of the grooves 14BL, 14BR is difficult to peel off, and it is restrained from starting from this portion. The skin-side material is peeled off in the entire area of the grooves 14BL, 14BR. Accordingly, it is possible to prevent the absorbent body 8 from deforming into a W-shape in the area corresponding to the urethral opening due to difficulty passing through the grooves 14BL and 14BR. also. Also in this case, it is preferable to pull the vicinity of the grooves 14BL, 14BR outward by the linear rubber 4R3.

In addition, in this embodiment, the grooves 14BL and 14BR are provided including the urethral opening-corresponding region to the anus-corresponding region 30 . In addition, the dorsal end of the grooves 14BL, 14BR is an anus corresponding region 30 . If a groove is formed on the back side of the anus-corresponding region 30, even if the absorber 8 is pulled outward in the width direction by an elastic member, the absorber 8 may be deformed in the front and rear of the anus-corresponding region 30. Force in a W-shaped cross section. In this embodiment, by arranging the back side end portions of the grooves 14BL, 14BR in the anus corresponding region 30, it is possible to prevent the force of deforming the absorber 8 into a W-shaped cross section from acting on the absorber before and after the anus corresponding region 30. 8.

Moreover, the diaper 1 is equipped with the linear rubber|gum 4F7 adhere|attached to the non-skin surface side rather than the absorber 8 in the extended state in the longitudinal direction. The linear rubber 4F7 is disposed in a region overlapping with the pair of grooves 14BL, 14BR, and expands and contracts in the longitudinal direction. The linear rubber 4F7 shrinks the inner cover sheet 5 and the cover sheet 4 which are the outer body, and pushes up the absorber 8 toward the skin surface. Thereby, the diaper 1 can raise the part which becomes convex toward the urethral opening side of the absorber 8 between a pair of groove|channel 14BL, 14BR by an exterior body to a skin surface side. Since the diaper 1 can abut the absorber 8 against the urethral opening, the adhesiveness of the absorber 8 to the wearer's skin can be improved.

In addition, the linear rubber 4F7 may be bonded to the absorber 8 without providing the linear rubber cover sheet 13 shown in FIG. 5 and FIG. 8 . Thereby, the absorber 8 is contracted in the front-rear direction, and the absorber 8 in the area corresponding to the urethral opening is easily deformed so that the cross section becomes a W-shape. In addition, the linear rubber 4F7 may be arrange|positioned in the area|region where the inner cover sheet 5 and the absorber 8 adhere|attach via the back sheet 6. When the linear rubber 4F7 is provided in this way, the absorber 8 is easily deformed into a W-shape, but in this embodiment, by pulling the absorber 8 outward with the linear rubber 4R3, it is possible to suppress the deformation of the anus corresponding area. At 30, the absorbent body 8 is deformed.

Moreover, linear rubber|gum 4F7 extends between the left-right paired groove 14AL, 14AR, when the diaper 1 is viewed planarly. In the region where the absorber 8 is folded starting from the grooves 14AL and 14AR to follow the groin, the exterior body shrinks in the longitudinal direction and floats toward the non-skin side to easily follow the legs. Deformed roots. Thereby, the diaper 1 can improve wearing feeling.

As described above, the linear rubber 4F7 extends between the grooves 14AL, 14AR and between the grooves 14BL, 14BR. As shown in FIG. 6 , the linear rubber 4F7 does not overlap with the linear rubber 4F2 for belly gathers when the diaper 1 is viewed planarly. The diaper 1 is thus configured so that a space is formed between the crotch region 1B side of the belly gathers and the wearer's skin surface, and urine in the left-right direction that reaches the front body region 1F side (abdominal side) easily goes around to the other side in the left-right direction. For example, when the wearer is a male, when the wearer urinates with the tip of the male sex organ facing either of the left and right directions, the urine tends to go around to the other side of the left and right direction, so the diaper 1 can suppress urine leakage.

In addition, the linear rubber 4F7 is arranged on the front body region 1F side rather than the region corresponding to the wearer's anus. With such a configuration, the diaper 1 lifts the outer body toward the skin surface by the contraction force of the linear rubber 4F7, thereby lifting the protruding portion of the absorber 8 between the grooves 14BL, 14BR toward the skin surface. However, in the anus-corresponding region 30, the absorber 8 is suppressed from lifting toward the skin surface side. The diaper 1 can easily separate the anus from the skin side of the diaper 1 .

The linear rubber 4F7 is arranged on the non-skin side of the absorber 8 . Moreover, the linear rubber 4F7 is provided in the center part of the width direction of the diaper 1, and the linear rubber 4F3 extends in the crotch region 1B so that it may pass through the area corresponding to the urethral opening. Here, the linear rubber 4F7 has a different color (for example, red, blue, etc.) from the exterior body and the absorber 8 , and can be visually recognized from the outside of the exterior body, that is, the outside of the cover sheet 4 . The diaper 1 according to this embodiment can visually confirm the intersection point of the linear rubber 4F7 and the linear rubber 4F3 from the outside on the abdominal side, but cannot visually confirm the intersection point on the back side, so that the front and rear can be distinguished more easily. In addition, the linear rubber 4F7 may be adhered to the non-skin surface side of the absorber 8 .

In addition, in the present embodiment, the grooves 14BL and 14BR overlap the linear rubber 4F3 when viewed in the thickness direction. Even when the absorber 8 is bent into a W shape along the grooves 14BL and 14BR, since the non-adhesive region 15 is provided, it is unlikely that the exterior body will be entangled in the unevenness generated in the absorber 8 and cannot be removed from the absorber 8. Visually confirm the linear rubber 4F3 from the outside.

In addition, when viewed in the thickness direction, the grooves 14AL, 14AR, 14BL, and 14BR on the ventral side are provided so as to overlap the non-adhesive region 15 . By providing the non-adhesive region 15, when the diaper is visually confirmed from the outside of the exterior body, the lines of the grooves 14AL, 14AR, 14BL, and 14BR on the skin side of the non-adhesive region are difficult to see or cannot be seen. . On the other hand, since no non-adhesive region is provided on the back side, when the diaper is visually confirmed from the outside of the exterior body, the lines of the grooves 14BL and 14BR on the back side are easily seen, or the lines are clearly seen. . Thereby, the diaper 1 can make distinction of front and back easy.

The absorbent body 8 has the absorbent core 8c which consists of several pads, and the core wrapping sheet 7 which wraps the absorbent core 8c. Moreover, in this embodiment, as shown in FIG. 9, the absorbent core 8c has the upper layer absorbent pad 8a and the lower layer absorbent pad 8b. The upper layer absorbent pad 8a has a substantially hourglass shape having a constricted portion, and the lower layer absorbent pad 8b has a rectangular shape. In addition, the width of the lower layer absorbent pad 8b is substantially the same as the width of the narrowed portion of the upper layer absorbent pad 8a. In the present embodiment, the upper layer absorbent pad 8a has a substantially hourglass shape narrowed near the center. In this way, the absorbent core 8c may be formed by laminating two absorbent pads.

<Other modifications>

As mentioned above, although this embodiment was demonstrated, the content of this invention is not limited to the said embodiment. In the above-mentioned embodiment, the absorber 8 and the inner cover sheet 5 are not bonded in the non-bonding region 15 where the linear rubber 4F3 traverses in the width direction, but they may be non-bonded as shown in FIG. 4 . In the region 15 the absorber 8 is partially bonded to the inner cover sheet 5 . In such a case, deviation of the absorber 8 with respect to the inner cover sheet 5 can be prevented. In addition, the place where the part is bonded may be, for example, the central part in the width direction.

In addition, in the above-mentioned embodiment, the exterior body on the front body region side and the exterior body on the back body region side are integrally formed, but the exterior body on the front body region side and the exterior body on the back body region side may be separately provided.
