Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding structure for disposable pants for children or adults having a waist opening and a pair of leg openings, and more particularly, to storing a plurality of disposable pants in a packaging bag. In doing so, the present invention relates to a folding structure of disposable pants for folding the pants so that they can be arranged and stored in a compact state.

[0002]

2. Description of the Related Art In addition to conventional disposable diapers which are formed into a pants-type at the time of wearing using a fastening tape, recently, disposable pants having both sides joined together and formed in a pants-like shape in advance have become commercially available. Became. Such disposable pants are disclosed in, for example, Japanese Utility Model Application Laid-Open No. 4-828, in which the left and right sides of the pants are folded inside the pants and then stored in a packaging bag. As shown, one of the left and right side portions (ear portions) of the pants is folded inside the pants, and one of the side portions is folded back to the outside of the pants and then stored in the packaging bag. Methods are known.

[0003] Disposable pants for infants can be packaged compactly simply by bending only the side portions of the pants and narrowing the width of the pants as in the prior art, but incontinent pants for adults. In the case of (1), since the entire size is large, there is a problem that the package cannot be compactly packed by simply bending the side portions of the pants.

[0004] In particular, in disposable pants in which the absorbent mat is provided only in the crotch part necessary for the incontinent person, a highly rigid absorbent mat is not provided on the upper part of the pants, and a fluttered material such as a nonwoven fabric is quite large. It only exists in the area. Furthermore, if a plurality of elastic bodies are added to this part to enhance the fit of the trunk, the upper part of the pants shrinks, so even if both sides of the pants are folded back as in the prior art described above. Conversely, it becomes an irregular shape,
Since the fluttering upper part of the pants remains, there has been a problem that handling when storing in the packaging bag is inconvenient, and that the pants cannot be stored neatly.

[0005]

Therefore, according to the present invention, in particular, one large disposable pants for adults,
An object was to provide a folding structure that can be compactly stored in a packaging bag with good handling.

[0006]

SUMMARY OF THE INVENTION The folding structure of the disposable pants according to the present invention is a disposable pants in which elastic bodies are provided at least around the waist opening and around the leg openings. Alternatively, it has a gist in that it is folded back with the upper part of the pants and the lower part of the pants being folded together. By adopting this configuration, the disposable pants are folded up and down and become compact,
Since the upper part of the pants, which is composed only of the fluttering flexible sheet, is in a folded state, it is easy to grasp it mechanically, and handling when storing it in the packaging bag becomes easy.

[0007] A folding structure in which the left and right sides of the pants are folded back to either the front side or the rear side of the pants, and the left and right sides of the pants are interposed between the upper and lower parts of the pants. Is adopted, the folded left and right side portions do not flutter and bend in different directions, and can be stored neatly in the packaging bag.

[0008] In the folding structure of the present invention, in particular, an absorbent body comprising a liquid-permeable sheet, a liquid-impermeable sheet, and an absorbent mat loaded between the two sheets, and the absorbent body are disposed inside. It is preferable that the present invention is applied to a disposable pants in which an outer sheet is provided and a plurality of elastic bodies are provided on the upper part of the disposable pants substantially in parallel with the elastic body around the waist opening over the entire circumference of the pants. The positional relationship between the plurality of elastic bodies attached to the upper part of the pants and the absorption mat is lower than that of the lowermost elastic body among the elastic bodies.
It is preferable that the upper edge of the absorbent mat be located on the crotch side so that the two do not overlap. With such pants, the upper part of the pants is overlapped with the lower part because the upper part of the pants is a laminate of a thin non-woven fabric and the like, and there is no thick absorbent mat. Folding does not increase the thickness of the folded pants.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory front view showing an example of disposable pants, and FIG. 2 is a partially exploded plan view. The disposable pants P are formed by folding a laminate having the outer sheet 1 and the absorbent main body 2 disposed inside the outer sheet 1 as main constituent members back and forth at the crotch, and bonding both side edges at the joining lines 3 and 3. , Waist opening H on the upper side of the pants
However, a pair of leg openings K, K are formed on the lower left and right sides of the pants, respectively. Around the waist opening H and the leg opening K, a plurality of stretched elastic bodies (thread-like or band-like) 51 and 52 are attached to form a gather portion that adheres to the wearer's skin. I have. When a plurality of other elastic bodies 53 are provided along the entire circumference of the pants under the waist gather elastic body 51 substantially in parallel with the elastic body 51, a torso fit gather is formed. Adhesion to the film is further enhanced.

As is apparent from FIG. 2, the outer sheet 1 is composed of two nonwoven fabrics 11, 12, and the elastic bodies 51, 52, 53 are respectively sandwiched between the two nonwoven fabrics. It is arranged so that. Outer sheet 1
May be a laminate of two or more nonwoven fabrics or films, and the sheets to be laminated need not have the same shape. For example, the outer sheet is extended from the opening edge of the waist and folded over the nonwoven fabric 12, and a separate nonwoven fabric is positioned between the folded nonwoven fabric 11 and the nonwoven fabric 12 so as to be positioned on the elastic body 52. It may overlap to the vicinity of the absorption main body 2.

An absorbent main body 2 is disposed inside the outer sheet 1, that is, on the wearer contact side. This absorption body 2
Liquid permeable sheet 21, liquid impermeable sheet 23, absorption mat 2
2, the absorbent mat 22 is loaded between the two sheets 21 and 23, and the sheet is bonded to the periphery of the sheet or the mat surface. Absorption mat 22
As for the pulp fiber, a mixture obtained by mixing pulp fiber, a superabsorbent resin, and, if necessary, a thermoplastic fiber and molding the mixture into a substantially rectangular shape or a substantially hourglass shape is generally used.

The liquid permeable sheet 21 is made of a liquid permeable nonwoven fabric for guiding liquid such as urine excreted into the absorption mat 22. A pair of rising gathers (not shown) may be provided on both sides of the upper surface of the liquid-permeable sheet 21 for the purpose of preventing urine leakage at the base of the leg. The liquid-impervious sheet 23 contains a liquid such as urine absorbed by the absorption mat 22,
This is for preventing leakage to the outer sheet side, and a flexible soft plastic film or the like is used.

In FIG. 1, the lowermost elastic body 53E located at the most inseam of the elastic body 53 for forming the body fit gathers.
Is preferably located above the waist side of the upper end edge 22E of the absorbent mat 22 in the absorbent main body 2. This is for preventing the elasticity of the elastic body from being hindered by the highly rigid absorbent mat. The upper part of such disposable pants is substantially composed of only a nonwoven fabric, and is fluttered, so that it is difficult to handle.

FIGS. 3 and 4 are explanatory views showing the folding structure of the present invention. In FIG. 3, the upper PU and the lower P of the pants
D, left side PSL and right side PSR.
The upper part PU of the pants is a part above the upper edge 22E of the absorption mat 22. When the upper PU and the lower PD of the pants are folded so as to overlap each other, if the absorption mat is folded, the thickness of the pants after folding becomes large. Therefore, it is preferable to dispose the absorption mat below the pants. The left side PSL of the pants is a part leftward of the left end of the absorbent mat, and the right side PSR is a part rightward of the right end of the absorbent mat.

FIGS. 4 (a) to 4 (c) show examples of folding for making the folding structure of the present invention. First, the left and right side portions PSL and PSR of the pants are folded back to the front (or rear) of the pants. Subsequently, the lower part of the pants may be folded so as to overlap the upper part of the pants. By folding the disposable pants in this way, the length of the pants is about half the length before folding, and it becomes a compact substantially rectangular shape that is almost the same width as the absorption mat, and the pants left and right sides composed only of fluttered nonwoven fabric Since the side is folded between the upper part and the lower part of the pants, it is easy to grasp mechanically. Also, at the time of packaging, since the substantially rectangular pants are packed side by side, the packaged bag after storage has a stable rectangular parallelepiped shape and does not fall down during display.

In the present invention, in addition to the folding structure shown in FIG. 4, the left and right side portions of the pants are folded back to the rear side of the pants, and the upper and lower portions of the pants are overlapped on the front side of the pants. A configuration in which the pants are folded back and forward is also included.

[0017]

The folded structure of the disposable pants according to the present invention is a structure in which the left and right sides of the pants are folded back to the front or the rear of the pants, and the upper and lower portions of the pants are folded so as to overlap each other. The large disposable pants for adults could be accurately held in a compact, approximately quadrilateral, approximately half the length and almost the same width as the absorber.
In addition, the upper part of the pants made of only the non-woven fabric is folded and overlapped with the lower part of the pants on which the absorption mat is provided, so that the pants can be easily gripped, so that the handling when storing in the storage bag is improved.

Furthermore, even if a predetermined number of disposable pants are arranged, they can be smoothly accommodated in a rectangular parallelepiped packaging bag without any part bulging or protruding abnormally. In addition, the stored packaging bags are not deformed into a distorted shape, and high-quality products in a beautiful packaging form can be provided.
