Description

  The present invention relates to an auxiliary sheet for diapers that is used attached to a diaper.

Nursing care and infant diapers include traditionally used cloth diapers and non-woven disposable diapers. For example, disposable diapers have a pants-type pant with a shape similar to pants. There is a tape type that is assembled and used in the shape of the above, or a pad type that is used by attaching to a diaper.
In these conventional diapers, urine cannot be absorbed quickly, and a gap is easily formed between the crotch and the diaper. There is.
For example, as shown in FIG. 8, Patent Document 1 has pleat portions 46 at both ends in the width direction of the diaper. Moreover, in patent document 2, as FIG. 1 shows, the both ends of the width direction are folded inward. Thus, urine is blocked by the pleated portion and the folded portion, and so-called side leakage from the end of the diaper is prevented.

JP 50-161347 A Japanese Patent No. 4678632

  By the way, in the disposable diaper, the excreted loose stool and urine are spread in the plane direction of the body-side surface material, and therefore, after excretion, the body-side surface material is likely to be in a state where the loose stool and urine remain attached. In particular, if it is soft stool, the diaper is not completely absorbed, and solid matter remains on the body-side surface material. This gives an uncomfortable feeling to the user. In addition, the state of attachment of soft stool or urine to the body-side surface material is the same for cloth diapers, and gives discomfort similar to disposable diapers.

In addition, although patent document 1 and 2 have a pleat part and a folding | returning part, this is an invention for the side leakage prevention to the last, and does not prevent the adhesion state of the excrement with respect to a body side surface material. That is, in Patent Documents 1 and 2, since the pleat portion and the folded portion are formed only at both ends in the width direction, when excreted, loose stool and urine are attached to the body-side surface of the central region. In addition, soft stool and urine are also attached to the pleated part and the folded part at both ends, so that the soft stool and urine are still attached. Therefore, in Patent Documents 1 and 2, user discomfort after excretion is inevitable.
Then, an object of this invention is to provide the auxiliary sheet | seat for diapers which avoids the unpleasant after excretion avoiding as much as possible that the loose stool and urine after excretion touch a body.

The above-described problem is a non-woven sheet that is worn separately from the diaper between the diaper and the user's crotch, and is formed by folding in a width direction corresponding to the width of the crotch A plurality of pleats, the plurality of pleats being arranged near the center in the width direction, and a pair of inner pleats whose front ends face each other on a surface arranged on the body side, and the inner pleats And a pair of outer pleat portions having distal end portions facing each other on a surface disposed on the body side relatively to the outer side in the width direction relative to the portion, and the inner pleat portion and the outer pleat portion respectively, the fold lines I spread the weight of excrement is solved by the diaper auxiliary seat in a state that fell in the space between the diaper.

This invention is a sheet | seat arrange | positioned between a diaper and its user's crotch. For this reason, if the sheet is attached to the crotch and then the diaper is worn, the diaper usually has a predetermined space between the crotch, and therefore there is a predetermined space between the sheet and the diaper. It is formed.
Here, in the diaper assisting sheet of the present invention, compared to a pair of inner pleat portions that are disposed near the center in the width direction and whose tip portions face each other on the surface disposed on the body side, And a pair of outer pleat portions whose front end portions face each other on the surface disposed on the body side relatively to the outer side in the width direction, and the inner pleat portion and the outer pleat portion are each excrement The crease spreads by the weight of the.
Then, for example, when excrement adheres between the pair of inner pleat parts or on the inner pleat part, the inner pleat part spreads by its weight and is displaced so as to fall into a predetermined space between the sheet and the diaper. Will do.
In addition, such an action is the same for the outer pleat portion.For example, when a large amount of loose stool or urine is excreted at once and the stool or urine spreads outward in the width direction from the inner pleat portion, The crease of the pleat part spreads and falls to the diaper side.
Further, even when excreted between the outer pleat portion and the inner pleat portion adjacent to each other, the folds of both the outer pleat portion and the inner pleat portion are spread, and it is possible to fall into the diaper side.

Thus, by having a pair of inner and outer pleat portions, the pleat portion is displaced so that the crease spreads according to the amount of excrement and the excretion position, and falls into the predetermined space.
And since the sheet is made of non-woven fabric, loose stool and urine adhering to the part that has fallen into the predetermined space are easily transmitted to the diaper side, and the fallen part is filled with soft stool and urine, and the body side It is prevented as much as possible from overflowing.
As described above, it is possible to effectively prevent loose stool and urine from spreading further on the surface of the sheet, and to reduce the area where the surface where soft stool and urine are attached touches the body, thereby reducing discomfort to the user. I can. In addition, as a result of the reduction of the area where soft stool and urine touch the body, for example, it is possible to suppress the transmission of soft stool and urine through the skin of a user lying down sideways, and therefore, the so-called side leakage prevention effect is also achieved. Effectively demonstrated.

Preferably, the tip portions of the pair of inner pleat portions and the tip portions of the pair of outer pleat portions all face the center in the width direction.
As a result, since loose stool and urine are usually excreted first in the center, the loose stool and urine are likely to enter and accumulate in the pleat folds. It becomes easy to be depressed.

Preferably, the seat is an area corresponding to at least the crotch at the time of mounting, and external force is applied to both ends in the width direction substantially along a length direction orthogonal to the width direction. It is characterized in that an elastic body is provided so as to exert tension when not applied.
Then, the corresponding area between the crotch of the seat can be curved so as to be convex toward the body by the force of the elastic body, thereby forming an auxiliary sheet for diapers that is easy to wear close to the crotch can do. Therefore, at the time of wearing, it is easy to form a predetermined space between the sheet and the diaper, and the pleat portion can be easily lowered to the diaper side.

Preferably, the pleat part has a plurality of holes and / or cuts, and the plurality of holes and / or cuts are formed on the body side of the body side buttocks and diaper side of the pleat part. It is formed only in the buttocks .
For this reason, the said excrement can be easily moved to the diaper side from the hole and / or cut of the part displaced so that excrement adheres and the pleat part falls to the diaper side. Therefore, it is possible to further reduce the discomfort given to the user by reducing the chance of excrement touching the body.

  As mentioned above, this invention can provide the auxiliary sheet for diapers which avoids the unpleasant feeling after excretion by avoiding as much as possible that the soft stool and urine after excretion touch the body.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
The embodiment described below is a preferred specific example of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.
Moreover, in the following drawings, the parts denoted by the same reference numerals have the same configuration.

The diaper auxiliary sheet (hereinafter referred to as “auxiliary sheet”) 20 in FIG. 1 is not intended to absorb and hold urine or the like like the diaper 10, but is used together with the diaper 10. It is for making the usability | use_condition of the diaper 10 favorable.
As shown in FIGS. 1 and 2, the auxiliary sheet 20 has a sheet shape that is long in one direction. The width direction X extends along the width direction of the crotch CR, and one end portion 20A in the longitudinal direction Y extends downward. The other end 20B is disposed on the waist side on the abdomen side, and then the diaper 10 is worn and used, whereby the diaper 10 is disposed between the crotch CR of the user HM. Is done.
Hereinafter, before describing the auxiliary sheet 20 of the present invention in detail, the relationship between the diaper 10 and the body, the method of using the auxiliary sheet 20, and the like will be described first.

The diaper 10 shown in FIG. 1 and FIG. 2 is also called a disposable or disposable diaper (diaper) or the like, and is a pant type having the same shape as a pant, or a so-called tape type that is assembled with a tape to form a pant. A back sheet 12 that prevents permeation of the skin, a surface material 14 made of a non-woven fabric disposed on the body side, and is disposed between the back sheet 12 and the surface material 14 to absorb urine that has passed through the surface material 14. And a thick absorber 16 in which a polymer to be held is mixed.
Such a diaper 10 is mounted in accordance with the curve of the lower abdomen and the buttocks of the user HM, whereas the crotch CR is curved so as to protrude upward, so that the crotch CR is usually used. A space S is generated between the two.
In addition, elderly people and sick persons who often spend their time in bed often hang down the diaper 10 along the buttocks where their muscles are thin and hang down, and a gap is often formed between the crotch CR. In addition, the cared person becomes thin around the thigh due to muscle contraction, but the adductor muscle 5 of the buttocks remains, so that a concave depression is generated from the inner thigh to the periphery 7 of the crotch CR, and the depression and the diaper 10 There are often gaps between the two. For this reason, the cared person is more likely to generate a space S between the diaper 10 and the crotch CR compared to a healthy person.
In addition, the auxiliary sheet 20 of the present invention is not limited to diapers for elderly people and care, but can also be used for diapers for infants.

Since the auxiliary seat 20 is characterized by using the space S generated between the crotch CR and the diaper 10 and displacing a pleat portion 40 (see FIG. 5) described later in the space S, the auxiliary seat 20 is mounted. In this case, it is preferable to use the crotch CR as close to or as close to the crotch CR as possible so that a required space S can be secured between the auxiliary sheet 20 and the diaper 10.
Specifically, when wearing, the diaper 10 is put on after the auxiliary sheet 20 is applied to the care receiver's crotch CR in the sleeping state. Even in this case, when a cared person who often spends sleeping is a user, the required space S can be formed between the auxiliary sheet 20 and the diaper 10.
In addition, the auxiliary sheet 20 in the figure has a length L in the front-rear direction during use so that the one end 20A and the other end 20B can be sandwiched between the diaper 10 and the user HM. For this reason, if both ends 20A and 20B are arrange | positioned at the lower abdomen side and waist | hip | lumbar part side which the diaper 10 closely_contact | adheres to the body, and if the diaper 10 is put on after that, one end part 20A will be on the lower abdomen side and the other end part 20B. Can be fixed to the waist side. Therefore, even if the user HM moves, the auxiliary sheet 20 can be easily held near the crotch CR.
Furthermore, a sticking portion such as a hot melt adhesive or a hook-and-loop fastener (not shown) is provided on the outer side (opposite to the user HM) of both end portions 20A and 20B, and this is applied to the surface material 14 made of a nonwoven fabric of the diaper 10. The detachable attachment is preferable, and this makes it easier to hold the auxiliary seat 20 near the crotch CR, even if the infant or the like whose movement is intense is the user HM.

[First Embodiment]
Next, the auxiliary sheet according to the first embodiment of the present invention will be described in detail mainly with reference to FIGS.
3 to 5 are auxiliary sheets 20 according to an embodiment of the present invention, FIG. 3 is a schematic perspective view thereof, FIG. 4 is a schematic cross-sectional view taken along line BB of FIG. 3, and FIG. It is the state figure which the crease | fold of the pleat part spread.
The auxiliary sheet 20 in these figures preferably absorbs loose stool and urine (hereinafter referred to as “excrement”) quickly and is permeable to the diaper side, and preferably uses a material that is comfortable to the touch, Nonwoven fabric is used as such a material. The nonwoven fabric can be a nonwoven fabric that has been subjected to hydrophilic treatment. For example, it is formed by fusing polyolefin, polyester, acrylic, etc. without using a binder by the thermal bond method, the spunbond method, the spunlace method, etc. The

3 and 4, the auxiliary sheet 20 is a single sheet 21 as a whole, and the width direction (short direction) X corresponds to the width of the crotch, and preferably floats from the crotch when worn. The size is the same as the width of the crotch so as not to leave. In addition, what is necessary is just to determine the dimension of the width direction X according to sex, age classification, and physique classification.
Further, the auxiliary sheet 20 in FIG. 3 has a substantially rectangular shape in plan view, but the shape of the present invention is not limited to this, and for example, as shown in the dashed line portion in FIG. The width dimension of the end portion 20A and / or the waist-side end portion 20B is made larger than the width dimension of the central portion 20C disposed on the crotch, thereby increasing the area sandwiched between the diaper 10 and the body. Then, the preferred mounting position of the auxiliary sheet 20 may be easily maintained.

Here, the auxiliary sheet 20 has a plurality of pleat portions (also referred to as flange portions) 40 formed by being folded in the width direction X. When the excrement adheres, the plurality of pleats 40 are displaced so as to fall into the space S on the diaper 10 side, as shown in FIG. 5 described later, due to the weight of the excrement. This is to prevent the surface from diffusing.
Specifically, as shown in FIG. 3 and FIG. 4, each pleat portion 40 has a fold 40 a that folds the sheet 21 along the longitudinal direction Y, and a fold 40 b that is further folded back. It is formed by a plurality of folds. The reason why the folds 40a and 40b are along the longitudinal direction Y is that if the folds are along the width direction X, urine or the like may be transmitted through the folds, and so-called side leakage may occur. Further, the reason that the folds 40a and 40b of each pleat part 40 are made two is that if the number of folds is large, the rigidity becomes too high and the displacement toward the diaper side becomes difficult, and the touch to the skin also deteriorates. Because there is a fear.
In addition, although the crease | fold 40a and the crease | fold 40b of this embodiment are mutually parallel, this invention is not limited to this.

  Such a plurality of pleat portions 40 are disposed on the outer side in the width direction X relative to the inner pleat portions 32 and 33 disposed near the center portion in the width direction X and the inner pleat portions 32 and 33. And an outer pleat portion 31. The position of the outer pleat part 31 and the position of the inner pleat parts 32, 33 are relative to each other. For example, the outer pleat part 31 does not necessarily have to be disposed at both ends 20D, 20E. What is necessary is just to arrange | position outside 33 of the width direction X from 33. In the present embodiment, the inner pleat portion 32 is disposed outside the width direction X in relation to the inner pleat portion 33, and therefore may be regarded as an outer pleat portion.

In the case of this embodiment, the outer pleat part 31 is formed on both ends 20D and 20E to form a pair, and on the surface 20F arranged on the body side, the two tip parts (folded folds) 40b, 40b is arranged so as to face each other with the inner pleat portions 32, 33 interposed therebetween.
Also, there are a plurality of inner pleat portions 32 and 33 as shown in the figure, and a pair of inner pleat portions in which two tip portions (folded folds) 40b and 40b face each other on the surface 20F arranged on the body side. 32, 32 and a pair of inner pleat portions 33, 33.
The pair of inner pleat portions of the present invention is not limited to two as shown in the figure, and may be one or three or more.

  Thus, when the excrement adheres to the region ER between the pair of inner pleat portions 33, 33, for example, as shown in FIG. 4, by making the two tip portions 40b, 40b face each other, The crease spreads with less resistance in the order of the crease 40a and the crease 40b, and the region ER to which excrement adheres can be easily dropped to the diaper side. That is, for example, as shown in the figure surrounded by the one-dot chain line in FIG. 4, when the tip portions 40b-1 and 40b-1 of the pair of inner pleats face each other, the fold line 40b-1 that is the tip portion is formed. The part 19 on the diaper side from the fold line 40a-1 prevents the force to spread. For this reason, the two tip portions 40b and 40b are opposed to each other as shown in the figures other than the figure surrounded by the one-dot chain line in FIG.

  Further, the tip portions (folded folds) 40b of the pair of inner pleat portions 33, 33, the tip portions 40b of the pair of inner pleat portions 32, 32, and the tip portions 40b of the pair of outer pleat portions 31, 31 are all of them. (That is, the front end portion 40b of the surface 20F disposed on the body side of all the pleat portions 40) faces the center CL in the width direction X. As a result, normally, since the excrement is first excreted in the central portion, the excrement easily enters the gap S1 between the pleats 40 and accumulates, and as a result, the pleat 40 has a weight of the accumulated excrement. It will be easier to drop on the diaper side.

As described above, in the preferred embodiment, in the surface 20F arranged on the body side, the distal end portions 40b, 40b have a plurality of pairs of inner pleat portions facing each other, and all the distal end portions 40b are wide. It faces the center CL in the direction X. In order to satisfy these two configurations at the same time, the pair of inner pleat portions 33, 33 closest to the center CL are directly opposed to the tip portions 40b, 40b with the center CL interposed therebetween. The pair of inner pleat portions 32, 32 outside the inner pleat portions 33, 33 are opposed to the tip portions 40b, 40b with the pair of inner pleat portions 33, 33 on the center CL side interposed therebetween. In the case of the figure, a plurality of pleat portions 40 arranged in the width direction X are formed symmetrically about the center CL in the width direction X.
Note that “a pair of inner pleat portions” means the inner pleat portions in a state where the two tip portions 40b and 40b face each other. Therefore, in the above description, for convenience of understanding, the two inner pleat portions 33 and 33 near the center CL are described as a pair, and the two outer pleat portions 32 and 32 outside the pair are described as a pair. The inner pleated portion denoted by reference numeral AB and the inner pleated portion denoted by reference numeral CD in FIG. 3 are also a pair of inner pleated portions.
Further, the present invention is not limited to such a mode. For example, as shown in FIG. 6, a pair of inner pleat portions 52 and 53, a pair of inner pleat portions 54 and 55, and a pair on a surface 20 </ b> F disposed on the body side. Each of the inner pleat portions 56 and 57 and the pair of inner pleat portions 58 and 59 may have their front end portions 40b and 40b directly opposed to each other without interposing other pleat portions.

As shown in FIGS. 3 and 4, the plurality of pleat portions 40 including the outer pleat portion 31 and the inner pleat portions 32 and 33 have their folds 40 a and 40 b widened by the required weight of excrement, respectively. It has become.
Specifically, as shown in FIG. 3 and FIG. 4, in a state where the pleat portions 40 are substantially lying, so that the plurality of pleat portions 40 do not overlap each other in the thickness direction Z (the state of FIG. 7). A predetermined interval X1 is provided between the pleat portions 40 adjacent to each other.
The spacing X1 may be reduced to form a large number of pleated portions 40. However, the spacing X2 between the pair of pleating portions 33, 33 adjacent to the center CL in the width direction X is larger than the other spacing X1. It is preferable to enlarge it. Thereby, even if the excretion position is slightly deviated from the center CL, the excrement can be stored as close to the center CL as possible.
Moreover, the pleat part 40 is fixed so that both ends (front and rear in use) in the longitudinal direction Y are not spread by the adhesive 18 or the like, thereby preventing a situation in which the excrement does not adhere and spread without darkness. .

The first embodiment of the present invention is configured as described above. For this reason, when excrement adheres to the center CL and reaches a required weight, as shown in FIG. The pair of inner pleats 33, 33 that are closest to each other spread and are displaced so as to fall (depress) toward the diaper 10 side. This effectively prevents the excrement from diffusing from the displaced portion 45 toward both ends in the width direction X.
Moreover, when the amount of excrement is large and excrement adheres to the inner pleat part 32 side outside the inner pleat part 33, for example, as shown in FIG. The inner pleat portion 32 also spreads and is displaced so as to fall on the diaper 10 side, and the diffusion of excrement can be effectively prevented.
Even when the excretion position is deviated from the center CL, for example, as shown in FIG. 5 (c), both the outer pleat portion 31 and the inner pleat portion 32 adjacent thereto expand to the diaper 10 side. It displaces so that it falls and can effectively prevent the spread of excrement.
And since the excrement adhering to these displaced parts 45 moves to the diaper 10 side at any time, overflowing to the body side is also effectively prevented.
Therefore, the area where the surface on which excrement adheres touches the body is reduced, and the discomfort given to the user can be reduced. Furthermore, as a result of the reduction of the area where the surface on which excrement adheres touches the body, for example, it is possible to suppress the transmission of soft stool and urine through the skin of a care recipient or the like lying down sideways. Side leakage prevention effect is also effectively demonstrated.

In addition, the width dimension of each pleat part 40 and the space | interval X1, X2 of FIG. 3 should just be determined in consideration of a user's physique, the softness | flexibility of a nonwoven fabric, etc., Preferably, when the pleat part 40 spreads and displaces As shown in FIG. 5, the width dimension and interval may be determined so that the bottom 45 a of the displaced portion 45 contacts the diaper 10. Thereby, the surface material 14 in which the fibers of the diaper 10 are densely can suck the excrement attached to the portion 45 displaced by the capillary phenomenon. In this regard, in the present embodiment, when the pair of inner pleat portions 33 and 33 spread and displace as shown in FIG. 5A, the inner pleat portion 32 and the outer pleat portion 31 spread as shown in FIG. 5C. When the inner pleat portion 33 and the outer inner pleat portion 32 are displaced, the bottom portion 45a of the displaced portion 45 comes into contact with the diaper 10 (not shown). ing.

[Second Embodiment]
Next, an auxiliary sheet according to a second embodiment of the present invention will be described with reference to FIGS.
FIG. 8 is a schematic perspective view of the auxiliary sheet 50 according to the second embodiment, and FIG. 9 is a schematic cross-sectional view of the CC portion of FIG. 8 in a state where the pleat portion 40 of FIG. 8 is expanded.
The auxiliary sheet 50 in these drawings differs from the auxiliary sheet 20 according to the first embodiment described above only in that holes or cuts are formed in the sheet 21.

  That is, the auxiliary sheet 50 has a plurality of holes or cuts (hereinafter simply referred to as “holes”) 26 so as to penetrate the thickness direction Z of the sheet 21. For this reason, when excrement adheres to the auxiliary sheet 50, for example, as shown in FIG. 9, the pleat portion 40 is displaced so as to fall on the diaper 10 side, and the excrement is moved to the diaper 10 side from the hole 26 of the displaced portion 45. It can be moved easily. Therefore, it is possible to effectively prevent the excrement adhered to the displaced portion 45 from overflowing to the body side, reduce the chance of excrement touching the body, and further reduce discomfort given to the user.

Specifically, as shown in FIGS. 8 and 9, since the auxiliary sheet 50 is formed of only one thin non-woven sheet 21 (excluding the adhesive 18 and the like), the ease of tearing is considered. The hole 26 is a circular hole.
Moreover, the hole 26 is arrange | positioned at the pleat part 40 instead of between the pleat parts 40 and 40 adjacent to each other. And since the pleated part 40 of the figure consists of two folds 40a and 40b, it has a body side collar part 40c and a diaper side collar part 40d, but the hole 26 faces the body side collar part 40c. Is formed. Thereby, since excrement becomes easy to accumulate in the crevice gap S1 of pleat part 40, pleat part 40 can fall to the diaper side without a problem by the weight of excrement.
Further, the size and shape of the hole 26 may be changed depending on the location. At this time, the hole 26-1 around the anus when worn is made larger than the hole 26-2 in other regions. preferable. Thereby, the soft stool can be moved to the diaper 10 side relatively easily.
In addition, in this embodiment, since excrement can move to the diaper 10 side from the hole 26, you may make the nonwoven fabric which forms the sheet | seat 21 into the fiber nonwoven fabric which performed the hydrophobic process.

[Third Embodiment]
Next, an auxiliary sheet according to a third embodiment of the present invention will be described with reference to FIGS.
10 is a schematic perspective view of the auxiliary sheet 60 according to the third embodiment, FIG. 11A is a DD schematic cross-sectional view of FIG. 10, and FIG. 11B is an EE schematic cross-sectional view of FIG. It is.
The auxiliary sheet 60 in these drawings is different from the auxiliary sheet 20 according to the first embodiment in that it has a curved sheet shape (in addition, FIG. 10 is a diagram in which the front side is curved so that it is convex. is there).

That is, the seat 21 which is the main body of the auxiliary seat 60 is at least a GG region corresponding to between the crotch at the time of mounting, and the front and rear direction at the time of mounting at both ends 60A and 60B in the width direction X of the crotch. An elastic body 77 such as a rubber cord is provided along (the longitudinal direction Y of the sheet 21).
The elastic body 77 exerts tension toward the central portion in the longitudinal direction Y in a state where the sheet 21 is expanded (in a state where no external force is applied to the sheet 21 as shown in FIG. 3).

The third embodiment of the present invention is configured as described above. For this reason, in a state where no artificial force is applied, the auxiliary sheet 60 is curved so that the central portion in the longitudinal direction Y is convex toward the body side due to the tension of the elastic body 77 as shown in the figure. . Note that the auxiliary sheet 60 is a thin sheet made of a nonwoven fabric, and since it is easily bent, the tension of the elastic body 77 may be small.
Therefore, even if the crotch is convex toward the head side, the auxiliary sheet 60 can be easily mounted close to the crotch, and the required space S (see FIG. 1) can be easily formed between the diaper. be able to.

By the way, this invention is not limited to the said embodiment, The separate structure of the above-mentioned embodiment may be abbreviate | omitted as needed, or may be combined with the other structure which is not demonstrated.
For example, the diaper used with the auxiliary sheet of the present invention is not limited to a disposable diaper, and may be a cloth diaper, for example.
Further, the auxiliary sheets 20, 50, 60 may exhibit elasticity in the Y direction (front-rear direction when attached) of FIGS. That is, when the auxiliary sheets 20, 50, 60 are manufactured, the auxiliary sheets 20, 50, 60 exhibiting stretchability in the Y direction can be formed with the non-woven fabric feeding direction (MD direction) being the X direction in the figure. Thereby, when excrement adheres, with respect to the X direction (width direction), the pleat portion 40 spreads and displaces to the diaper side as described above, and the Y direction extends to the diaper side due to the elongation of the fiber itself. Therefore, not only in the width direction of the crotch but also in the front-rear direction at the time of wearing, the spread of loose stool or the like can be suppressed.
