Description

  The present invention relates to a pad holder used in combination with an absorbent pad.

  Conventionally, the pad holder is worn with the absorbent pad attached to the skin-facing surface of the crotch part of the pad holder, and after the absorbent pad absorbs the liquid, the absorbent pad alone is replaced with a new one. The holder is reused. Such a pad holder holds the absorbent pad in a state fitted to the wearer's crotch, and the amount of dust and cost can be reduced by using the pad holder in combination with the absorbent pad. Can do.

  Known as a conventional pad holder is a pad holder that is formed from an elastic sheet, has a waist opening and a pair of leg openings, and is worn with an absorbent pad on the skin facing surface of the crotch Yes. In particular, a boxer brief type pad holder, that is, a type of pad holder in which the opening periphery of the leg opening is located below the crotch when worn, is widely used. In such a boxer brief type pad holder, For the purpose of preventing the absorbent pad attached to the crotch part of the pad holder from protruding to the outside, a leg elastic member is disposed on the peripheral edge of each pair of leg openings to form a thigh gather The thigh gather is adapted to tighten the thigh of the wearer (see, for example, Patent Document 1).

  In addition, the applicant previously proposed a pad holder in which a gather formed along the opening peripheral edge of the leg opening and a gather formed along the wearer's ridge (see Patent Document 2). ).

Japanese Patent Laid-Open No. 2002-660 JP 2008-284038 A

The conventional boxer brief type pad holder as disclosed in Patent Document 1 has a thigh gather for tightening the wearer's thigh at the periphery of the opening of the leg opening, so that when the holder is pulled down, The opening peripheral edge of the leg opening is caught on the wearer's leg, particularly the thigh, and it takes time and labor to re-patch the hooked part to lower the entire holder to an appropriate position. Such a problem is particularly noticeable when the pad holder is formed using a material that is easily stretched. In the case of Patent Document 2, the same problem occurs when it is formed using a material that is particularly easily stretched.
On the other hand, if the gathers etc. that tighten the thigh are not formed at the opening periphery of the leg opening, the pulling-up performance will improve, but the opening periphery will turn over during use, and the absorbent pad will be exposed to the outside and leak-proof May be reduced.

  Therefore, in the present invention, the opening peripheral edge of the leg opening is difficult to be caught on the wearer's leg (particularly the thigh) when pulling down, and the wearability is excellent, and the opening peripheral edge is turned up and absorbed. The present invention relates to a pad holder that does not easily expose the pad.

  [Technical Field] The present invention provides a stretchable pant that includes a stretchable sheet, has a waist opening and a pair of leg openings, and is worn with an absorbent pad on the skin facing surface of the crotch. It is a type | mold pad holder, Comprising: The stress relaxation rate after 80-% expansion | extension 10 minutes of the opening peripheral part of the said leg opening part is provided in 30-60%.

  When the pad holder of the present invention is pulled down, the opening peripheral edge of the leg opening is not easily caught on the wearer's leg (particularly the thigh), and is excellent in wearability, and the opening peripheral edge is turned up and absorbed. The exposure of the sexual pad is difficult to occur.

It is the front view which looked at the state (natural state) which made one embodiment of the pad holder of the present invention the surface opposite to the skin of the front body and the back body made into a plane form (natural state) from the front body side. It is the figure which looked at the use condition (wearing condition) of the pad holder shown in FIG. 1 from the front body side. It is the rear view which looked at the state (natural state) which made the pad holder shown in FIG. 1 contact | abut the skin opposing surfaces of a front body and a back body, and was made into planar shape from the back body side. It is the figure which looked at the use condition (wearing condition) of the pad holder shown in FIG. 1 from the side. It is explanatory drawing of the measuring method of a stress relaxation rate.

Hereinafter, the pad holder of the present invention will be described with reference to the drawings based on preferred embodiments thereof.
As shown in FIG. 1 (natural state), the pad holder 1 of the present embodiment has a pant-shaped configuration, and has a waist opening 5 and a pair of leg openings 6 and 6.
The pad holder 1 has a front body 2 disposed on the wearer's abdomen when the pad holder 1 is worn, and a back body 3 disposed on the wearer's back when the pad holder 1 is worn. Yes.

The pad holder 1 is worn in a state in which an absorbent pad 7 is arranged on the skin facing surface of the crotch part 4 (surface directed toward the wearer's skin when the pad holder is worn) as shown in FIG. . The crotch part 4 is a part disposed in the crotch part of the wearer when worn. The absorbent pad 7 generally includes a liquid-permeable top sheet, a liquid-impermeable or water-repellent back sheet, and an absorbent core sandwiched and fixed between the two sheets. The absorbent pad 7 may or may not have a fixing means (such as an adhesive portion) for fixing to the pad holder 1 on the surface on the back sheet side.
As shown in FIG. 1, the pad holder 1 is formed symmetrically with respect to a longitudinal center line CL extending in the longitudinal direction of the diaper.

  The waist opening 5 is a portion through which the waist portion of the wearer is inserted, and a waist opening elastic portion 51 is formed in an annular shape at the periphery of the opening. Moreover, a pair of leg opening parts 6 and 6 are parts through which a wearer's leg is penetrated, and the leg opening elastic part 61 is formed cyclically | annularly in each opening peripheral part.

  The pad holder of the present invention includes an elastic member. More specifically, almost the entire pad holder is made of an elastic sheet. The stretchability of the pad holder appears at least in the width direction of the holder (the direction along the waistline direction). In the longitudinal direction of the pad holder (the direction from the waist opening toward the crotch), it is not necessary to have stretchability, and it is only necessary to exhibit extensibility. However, by having vertical stretchability (especially the buttocks to the back waist), it becomes easier for the holder to follow the elongation of the skin near the buttocks due to movements such as walking and standing, and it is easy to suppress the occurrence of slipping off. This is preferable. Moreover, it is preferable from the point that it becomes easy to follow a complex shape having irregularities such as the abdomen (particularly the abdomen of the elderly) and the buttocks and the like, and the fitting property is good.

The opening peripheral edge of the leg opening 6 in the present embodiment preferably has a stress relaxation rate after 10 minutes of 80% elongation (hereinafter also referred to as post-elongation stress relaxation rate) of 30 to 60%, more preferably 35. ~ 55%.
In the present invention, when the pad holder is pulled up and attached, the post-elongation stress relaxation rate is used as an index of how much the opening periphery of the leg opening 6 contracts over time after being expanded by the legs. Used.
If the post-elongation stress relaxation rate is 30% or more, the opening peripheral portion of the leg opening 6 of the pad holder does not excessively tighten the wearer's thigh, and a low-stimulation wearing feeling is achieved. Furthermore, since the opening peripheral edge of the leg opening 6 can be easily pulled down without being caught by the thigh when pulled down, the pad holder can be lowered easily and in a short time even in the case of emergency such as during toilet excretion. be able to. When the post-elongation stress relaxation rate is 60% or less, the opening periphery of the leg opening 6 of the pad holder is along the thigh of the wearer during movement of the wearer, and the absorbent pad is exposed to the outside and leak-proof. Can be prevented from decreasing. Further, by suppressing the occurrence of irregular sag, it is possible to prevent the outer garment from resonating and to prevent the silhouette at the time of wearing from being deteriorated.

The post-elongation stress relaxation rate is the highest (waist opening portion) of the folding line 1b generated in the crotch part 4 of the holder when the skin facing surfaces of the front body 2 and the back body 3 are brought into contact with each other to form a flat natural state. The leg-around portion 63 extending downward from the uppermost point 62 located on the side) is cut out in an annular shape, and is used as a test body 8. The test body 8 has a distance W (longitudinal center line) from the uppermost point 62 to the lower end of the leg-around portion 63 at a portion where the width W is near the longitudinal center line CL on either the front body side or the back body side. (Measured along CL) Cut out to be the same as L1.

  The distance L1 is preferably 10 to 130 mm, more preferably 20 to 100 mm, and still more preferably 30 to 70 mm.

The stress relaxation rate after elongation is measured according to the stress relaxation rate [Method A (single load method)] defined in JIS L 1096.
However, as shown in FIG. 5, the test body 8 passes two U-shaped first jigs 81 inside the ring of the test body 8 and fixes them to the tensile tester. In FIG. 5, reference numeral 82 denotes a sample fixing chuck, and reference numeral 83 denotes a tensile tester main body connecting portion. The test body 8 is set in the tensile tester so that the initial length L0 is the same as the natural length L around the leg in the pad holder (see FIG. 1). Then, one of the first jigs 81 is moved, and the test body 8 is extended to an elongation rate of 80% at a tensile speed of 300 mm / min. An elongation rate of 80% means that the specimen 8 is elongated by 80% of the initial length L0 (same as the natural length L), and the length LE after elongation is 1.80 times the initial length L0. is there.
Then, from the load (P1) immediately after being stretched to an elongation rate of 80% and the load (P2) after being stretched to an elongation rate of 80% and left to stand for 10 minutes, the post-stretch stress relaxation rate ( %).
Stress relaxation rate after elongation (%) = {(P1-P2) / P1} × 100

  In the pad holder 1 of the present embodiment, the knitting method of the part forming the leg opening elastic part 61 is changed to the other part so that the post-extension stress relaxation rate of the opening peripheral edge part of the leg opening part 6 falls within the specific range. Unlike the above knitted fabric, the leg opening elastic portion 61 is formed by forming a knitted knitted fabric (a method of alternately performing flat knitting and tuck knitting), and folding the knitted fabric into a multilayer. In the folded portion, the folded end portion may be fixed to either the inner surface or the outer surface of the holder. The leg-around portion 63, particularly the portion forming the leg opening elastic portion 61, is preferably made of a knitted fabric containing no elastomer material. Here, the elastomer material may include a synthetic rubber such as styrene-butadiene, butadiene, isoprene, and neoprene, and a stretchable material such as natural rubber, EVA, stretchable polyolefin, and urethane. Examples of the cross-sectional shape include a rectangular shape, a square shape, a circular shape, a polygonal shape, a multifilament type and the like, a thread shape, a string shape, a belt shape, and a film shape.

  Of course, a method different from the present embodiment may be used as a method of setting the post-elongation stress relaxation rate of the opening peripheral edge of the leg opening 6 to the specific range. For example, the post-elongation stress relaxation rate is 20% to 60%, preferably 30% to 50% of elastomer material is disposed in a stretched state on a knitted fabric, woven fabric, nonwoven fabric, or the like, or the elastomer material is unstretched on a knitted fabric, stretched nonwoven fabric, etc. A method of arranging the leg opening elastic part 61 is different from the knitting fabric of the other part in the knitting method of the part forming the leg opening elastic part 61, and the leg opening elastic part 61 is formed as a single layer without being folded. Etc.

In the present embodiment, the waist opening elastic part 51 is formed by folding an elastic sheet in the same manner as the leg opening elastic part 61 and fixing its end to the inner surface (or outer surface) of the holder. Each of the waist opening elastic portions 51 can also be formed by attaching another elastic member, for example, a stretchable woven fabric or nonwoven fabric containing a polyurethane fiber, a synthetic rubber sheet, a natural rubber sheet, or the like. Further, the leg opening elastic part 61 and the waist opening elastic part 51 may have the same or different configurations.
Due to the presence of the waist opening elastic portion 51, the opening peripheral edge portion of the waist opening portion 5 can tighten the wearer more strongly than the annular portion made only of the elastic sheet existing immediately below when the pad holder 1 is worn. it can. Similarly, the opening peripheral part of each leg opening part 6 and 6 can clamp a wearer a little stronger compared with the annular part which exists just above this opening peripheral part in each leg opening part 6. FIG.

In the pad holder 1 of the present embodiment, the portions A and A that are present on the left and right sides of the front body 2 and cover the thighs of the wearer have elasticity in the lateral direction (X direction) of the pad holder. Yes. And each of the left and right side portions A, A has thigh stretchable parts 20, 20... And thigh extension suppressing parts 23-25 extending in the lateral direction of the pad holder.
The portions A and A covering the thigh of the wearer are portions that are separated from the longitudinal center line CL on both sides of the longitudinal center line CL extending in the longitudinal direction of the diaper. The waist opening 5 and the leg opening The opening periphery of each part 6 is not included. The leg opening elastic part 61 in the pad holder 1 of this embodiment does not correspond to the thigh extension suppressing part in the present invention.

  In the front body 2 of the pad holder 1 of the present embodiment, as shown in FIG. 1, a pair of left and right extension suppressing portions 21 and 22 are respectively provided from the center side in the width direction of the lower half 2D of the front body. It is formed in a strip shape over the side of the portion 2U. As shown in FIG. 1, the front body lower half 2D is a portion located below a straight line L21 that bisects the crotch length L2 of the front body 2, and the front body upper half 2U is the same straight line. It is a part located above L21.

As shown in FIG. 1, the extension restraining portions 21 and 22 have the end portions 21 a and 22 a on the upper half 2U side of the front body so that the pad holder 1 is in contact with the skin facing surfaces of the front body 2 and the back body 3. Therefore, it is preferable to reach the folding lines 1a and 1a generated on the side of the holder when the flat natural state is obtained. The end portions 21a and 22a do not have to reach the folding lines 1a and 1a, respectively. In this case, the shortest distance to the folding lines 1a and 1a is preferably 30 mm or less, particularly preferably 10 mm or less.
Moreover, as shown in FIG. 1, as for the expansion | extension suppression parts 21 and 22, the edge parts 21b and 22b by the side lower part 2D side of the front body have entered into the area | region 41 between a pair of leg opening parts 6 and 6, as shown in FIG. It is more preferable that the folding line 1b generated in the crotch part 4 is reached when the skin facing surfaces of the front body 2 and the back body 3 are brought into contact with each other to form a flat natural state. The end portions 21b and 22b may not reach the folding line 1b, respectively. In this case, the shortest distance to the folding line 1b is preferably 50 mm or less, particularly 10 mm or less.
The lower ends of the front body lower half 2D and the back body lower half 3D are the crotch 4 when the pad holder 1 is brought into a planar natural state by contacting the skin facing surfaces of the front body 2 and the back body 3. It is the position of the folding line 1b which arises.

  The distance in the width direction of the region 41 between the pair of leg openings 6 and 6 (the direction along the width direction of the pad holder corresponding to the space between the leg opening edges on the folding line 1b generated in the crotch 4 in the natural state (the X direction) )) Is preferably 3 to 15 cm, more preferably 6 to 12 cm from the viewpoint of improving the adhesion of the pad holder 1 and the absorbent pad 7 to the wearer's crotch. Moreover, it is preferable that the expansion | extension suppression parts 21 and 22 do not cross | intersect mutually in front body lower half part 2D.

  In the pad holder 1 of the present embodiment, a region (hereinafter also referred to as a leg region) sandwiched between the extension suppressing portion 21 or 22 and the folding line 1a on each of the left and right sides of the front body 2 is large for the wearer. It is the parts A and A covering the thigh, and the leg regions A and A have the above-described thigh stretchable part 20 and thigh stretch suppressing parts 23 to 25.

As shown in FIG. 1, the thigh extension suppressing portions 23 to 25 are formed to extend in the lateral direction of the pad holder (corresponding to a direction along the waistline direction). Further, a plurality of thigh extension suppressing portions 23 to 25 (three in the illustrated example) are formed at intervals in the vertical direction of the pad holder.
From the viewpoint of providing a better wearing feeling with less irritation to elderly people who are sensitive to skin irritation, the length of the thigh extension suppression portions 23 to 25 in the vertical direction of the pad holder is the thigh expansion / contraction located above and below it. The length of the portion 20 is preferably shorter than the length in the same direction. The length in the vertical direction of the pad holder of the thigh extension suppressing portions 23 to 25 may be changed from the laterally outward direction to the inward direction of the pad holder 1.

The elongation restraining portions 21 and 22 (the same applies to backside stretching restraining portions 31 and 32 to be described later) have a maximum elongation rate in the vertical direction of the pad holder on both sides of the stretch restraining portion in the waist part of the front body or the back body. A portion made smaller than at least one portion, or at least on both sides of the stretch suppression portion in the waist portion of the front body or the back body when the specific load is applied in the longitudinal direction of the pad holder It is a part made smaller than the part located in one side. The former is preferable from the viewpoint of detachability and wearing feeling.
The maximum elongation rate is the elongation rate when the material is stretched to a length that cannot be further stretched (the length immediately before material breakage), and the maximum elongation rate is obtained by the following formula (1).
Maximum elongation rate (%) = {(length after stretching−length before stretching) / length before stretching} × 100% (1)

The maximum extension rate of the extension suppressing units 21 and 22 is preferably less than 180%, more preferably 20 to 150%, and still more preferably 40 to 120%.
In the front body 2, the maximum elongation rate (Y direction) of the portions other than the stretch suppressing portions 21 and 22 (highly stretchable portions), for example, the highly stretchable portions located on both sides of the stretch restraining portion 21 (22). ) Is preferably 120% or more from the viewpoint of ease of attachment and detachment of the pad holder and a feeling of wearing, and the difference from the maximum elongation rate of the elongation suppressing portion 21 (22) is 30% or more, particularly 50 to It is preferably 150%.

The maximum extension rate of the extension suppressing unit 21 (22) is measured by extending the extension suppressing unit 21 (22) in the longitudinal direction (Y direction) of the pad holder.
On the other hand, the maximum elongation ratio (Y direction) of the highly extensible portion other than the elongation suppressing portion 21 (22) is measured by extending the highly extensible portion in the longitudinal direction (Y direction) of the pad holder.

[Maximum elongation rate measurement method of the elongation suppression unit 21 (22)]
A rectangular shape having a size of 100 mm in the vertical direction (Y direction) and 50 mm in the width direction (X direction) from the pad holder to be measured, and at least 60 mm in the center in the longitudinal direction (Y direction) of the measurement sample It cut out so that the expansion | extension suppression part 21 (22) may be included over this, and let this cut-out rectangular shape be a sample for a measurement. In addition, although the said sample adjustment method presupposes that the expansion | extension suppression part 21 (22) has been arrange | positioned continuously over the full range of 60 mm, the expansion | extension suppression part 21 (22) is parted and divided. This category also includes intermittently high extensibility parts.
The measurement sample is attached to a chuck of a tensile tester so that the longitudinal direction (corresponding to the Y direction) is the tensile direction. At this time, it is confirmed that the extension suppressing portion 21 (22) is sandwiched in any of the upper and lower chucks. The distance between chucks is 50 mm (the chuck part is a part 25 mm before and after the measurement sample). The measurement sample is pulled at 300 mm / min, and the distance between chucks is measured when at least a part of the measurement sample is broken.
However, when the sample for measurement does not break even after 100N load, the distance between chucks at 100N load is measured.
If the sample cannot be taken out from the pad holder to be measured as described above, the sample length, sample width, distance between chucks, and chuck width may be changed as appropriate.

  The method for measuring the maximum elongation rate (Y direction) of the portion (longitudinal highly extensible portion) other than the elongation suppressing unit 21 (22) is the same as described above. However, when the measurement sample is cut out, the elongation suppression unit 21 (22) is not included in the measurement sample. However, the thigh extension suppressing portions 23 to 25 may be included in the measurement sample.

In the thigh extension suppressing portions 23 to 25, the maximum extension rate in the lateral direction (also referred to as the width direction) of the pad holder is positioned on both sides of the leg regions A and A (especially the thigh extension suppressing portion). The part that is made smaller than the part to be stretched), or the other part of the waist part of the front body or the back body when the specific load is applied in the lateral direction of the pad holder It is the part made smaller than the part located in the both sides.
The maximum elongation rate is obtained by the above formula (1).

The maximum extension rate of the thigh extension suppressing portions 23 to 25 is preferably less than 200%, more preferably 50 to 180%, and still more preferably 70 to 160%.
In the leg region A, the maximum extension of each of the stretchable parts 20, 20... Located above and below the highly stretchable part other than the thigh extension suppressing parts 23 to 25, for example, the thigh extension suppressing parts 23 to 25. The rate (X direction) is preferably 200% or more from the viewpoint of ease of attachment / detachment of the pad holder, the feeling of wearing, and the retention of the absorbent pad, and the maximum extension rate of the thigh extension suppressing portions 23 to 25 The difference is preferably 20% or more, particularly 30 to 130%.
Further, the pad holder 1 is a portion where 50% or more, more preferably 70% or more, of the area of the leg region A in the natural state is more extensible than the thigh extension suppressing portions 23 to 25, that is, a thigh stretchable portion. It is preferable from the standpoint of ease of attaching and detaching the pad holder and a feeling of wearing.
The maximum extension rate of the thigh extension suppression units 23 to 25 is measured by extending the thigh extension suppression units 23 to 25 in the lateral direction (X direction) of the pad holder.
The maximum extension rate (X direction) of the thigh stretchable parts 20, 20... Located above and below the thigh stretch suppressing parts 23 to 25 extends the thigh stretchable part in the lateral direction (X direction) of the pad holder. And measure.

[Method for Measuring Maximum Extension Ratio of Thigh Elongation Suppression Units 23 to 25 and Thigh Elasticity Part 20]
From the pad holder to be measured, it has a rectangular shape with dimensions of 100 mm in the width direction (X direction) and 50 mm in the longitudinal direction (Y direction), and at least one in the center in the longitudinal direction (corresponding to the X direction) of the measurement sample. The two thigh extension suppressing portions 23 to 25 are cut out so as to be included over a range of at least 60 mm, and the cut out rectangular shape is used as a measurement sample. The sample preparation method is based on the premise that the thigh extension suppressing portions 23 to 25 are continuously arranged over the entire length of 60 mm, but the thigh extension suppressing portions 23 to 25 are partly divided. Thus, a configuration including the thigh stretchable part 20 is also included in this category.
The measurement sample is attached to a chuck of a tensile tester so that the longitudinal direction (corresponding to the X direction) is the tensile direction. At this time, it is confirmed that at least one of the thigh extension suppressing portions 23 to 25 is sandwiched in any of the upper and lower chucks. The distance between chucks is 50 mm (the chuck part is a part 25 mm before and after the measurement sample). The measurement sample is pulled at 300 mm / min, and the distance between chucks is measured when at least a part of the measurement sample is broken.

However, when the sample for measurement does not break even after 100N load, the distance between chucks at 100N load is measured.
If the sample cannot be taken out from the pad holder to be measured as described above, the sample length, sample width, distance between chucks, and chuck width may be changed as appropriate.
The measuring method of the maximum elongation rate (width direction) of the thigh stretchable part 20 conforms to the above. However, when cutting out the measurement sample, the measurement sample does not include the thigh extension suppressing portions 23 to 25. However, the extension suppressing portions 21 and 22 may be included in the measurement sample.
In addition, the thigh extension suppressing parts 23 to 25 say that “the extension rate when a specific load is applied in the longitudinal direction of the pad holder is smaller than the peripheral part” means that excrement is applied to the pad in a normal wearing state. Assuming a held state, it means that the expansion rate is small when compared with the expansion rate at the time of 3N weighting. The preparation method and measurement method of the measurement sample are performed according to the measurement method of the maximum elongation rate except for the weighted value.

  The width of the thigh extension suppressing portions 23 to 25 is not particularly limited. For example, the width of the illustrated example is about 0.5 to 5 cm. Further, the extension suppressing portions 21 and 22 extend to the waist region side (upper side) from the position of the thigh extension suppressing portion 23 closest to the waist opening 5.

As shown in FIG. 3, the pad holder 1 of the present embodiment has a pair of left and right dorsal extension restraining portions 31 and 32 on the back body 3.
The dorsal side stretch suppression portions 31 and 32 are each formed in a band shape from the center in the width direction of the lower back half 3D to the side of the back upper half 3U. As shown in FIG. 3, the back body lower half 3D is a portion positioned below a straight line L31 that bisects the crotch length L3 of the back body 3, and the back body upper half 3U is the same straight line. It is a part located above L31.

As shown in FIG. 3, the dorsal extension restraining portions 31, 32 are arranged so that the end portions 31 a, 32 a on the back body upper half 3 U side connect the pad holder 1 to the skin facing surfaces of the front body 2 and the back body 3. It is preferable to reach the folding lines 1a and 1a generated on the sides of the holder when the flat surface is brought into a natural state by interviewing. The end portions 31a and 32a do not need to reach the folding lines 1a and 1a, respectively. In this case, the shortest distance to the folding lines 1a and 1a is preferably 30 mm or less, particularly 10 mm or less.
Moreover, as shown in FIG. 3, as for the back side expansion | extension suppression parts 31 and 32, the edge parts 31b and 32b by the side lower half part 3D of the back body have penetrated to the area | region 41 between a pair of leg opening parts 6 and 6. It is preferable that the skin facing surfaces of the front body 2 and the back body 3 are in contact with each other to form a flat natural state, and it is more preferable that the folding line 1b generated in the crotch part 4 is reached. The end portions 31b and 32b do not have to reach the folding line 1b, but in that case, the shortest distance to the folding line 1b is preferably 50 mm or less, particularly preferably 10 mm or less.

  In the pad holder 1 of the present embodiment, the extension restraining portions 21 and 22 of the front body 2 and the back side elongation restraining portions 31 and 32 of the back body 3 are connected to each other at a portion disposed on the side of the wearer. . Thereby, the pulling-up property when the pad holder 1 is pulled up and mounted is further improved. Moreover, the expansion | extension suppression parts 21 and 22 and the back | dorsal side expansion | extension suppression parts 31 and 32 of the front body 2 are connected substantially also in the site | part distribute | arranged between a wearer's crotch. Thereby, the pulling-up property when the pad holder 1 is pulled up and mounted is further improved.

  Since the post-extension stress relaxation rate of the opening periphery of the leg opening 6 is within the specific range, the pad holder 1 of the present embodiment is worn by the opening periphery of the leg opening when the holder is pulled down. It is difficult to get caught on a person's leg part, especially a thigh part, and it is easy to pull down the whole holder to an appropriate position. Moreover, the post-elongation stress relaxation rate of the opening periphery of the leg opening 6 is within the specific range, the opening periphery does not excessively tighten the wearer's thigh, and the wearer Therefore, inconvenience that the peripheral edge of the opening is turned over and the absorbent pad is exposed to the outside during use is prevented. In addition, the displacement of the absorbent pad hardly occurs.

Moreover, even if it is a case where high extensibility is provided to the wide range of the front body and / or the back body by forming the expansion | extension suppression parts 21 and 22 in the aspect mentioned above, the front half side of the front body When the pad holder is lifted by gripping the vicinity of the portion, the force is easily transmitted directly or indirectly to the leg-around portion 63, the leg opening elastic portion 61, or the like via the extension suppressing portions 21 and 22. Therefore, it is easier to pull up the entire holder including the opening peripheral edge of the leg opening. For example, the entire holder can be easily moved to the proper position by reducing labor and time such as reworking the hooked part. Can be raised.
From the viewpoint of obtaining such an effect, it is preferable that the extension suppressing units 21 and 22 do not intersect each other at least in the upper front half 2U.

Further, the pad holder 1 of the present embodiment has the thigh stretchable part 20 and the thigh stretch suppressing parts 23 to 25 in the leg region (the part covering the thigh) A of the front body 2 in the manner described above. Therefore, the leg region (portion covering the thigh) A is in close contact with the wearer's skin without being loosened by the action of the thigh extension suppressing portions 23 to 25, and the wearer of the thigh stretchable portion 20 Since the normal resistance against the skin is smaller than the normal resistance of the thigh extension suppressing portions 23 to 25, the frictional force between the pad holder 1 and the wearer's skin during attachment / detachment is small and the attachment / detachment is excellent.
This makes it possible to achieve both the adhesion of the leg region (the portion covering the thigh) A to the skin and the ease of attachment / detachment. As a result, the pad holder can be lowered easily and in a short time even when urgent, such as when the toilet is excreted. The clothes will not be soiled. In addition, by suppressing the occurrence of irregular slack, the wearing feeling is excellent, and the silhouette at the time of wearing is not deteriorated in order to prevent it from reverberating in the outer garment.

  In the present invention, only one thigh extension suppressing portion may be provided on each of the left and right sides of the front body 2, but a plurality of thigh extension suppressing portions are formed at intervals in the vertical direction of the pad holder as in the present embodiment. Even when various types of absorbent pads are used, the absorbent pad is less likely to be displaced in order to ensure that the peripheral edge of the absorbent pad is in close contact with the skin, which is preferable from the viewpoint of leakage prevention.
