Description

The present invention relates to an absorbent article.

Conventionally, there is known an absorbent article that includes a pad body having a top sheet that contacts the wearer's skin, a back sheet, and an absorbent body disposed between them, and that is attached to an outer article when used (see, for example, Patent Documents 1 and 2). After use, such an absorbent article is discarded by the disposer in a folded or rolled state with the soiled top sheet on the inside.

Here, Patent Document 1 discloses an absorbent article in which adhesive parts are provided on the outer surfaces of both longitudinal ends of the pad body. When the absorbent article disclosed in Patent Document 1 is disposed of, the areas where the adhesive parts are provided (both longitudinal ends of the pad body) are folded toward the top sheet, and the adhesive parts are bonded together, thereby maintaining the folded-in-two discarded shape with the top sheet on the inside. Patent Document 2 discloses an absorbent article in which a deployable post-treatment tape is provided on the outer surface of the pad body. In the absorbent article disclosed in Patent Document 2, the pad body is rolled up after use, and the post-treatment tape is wrapped around it to maintain the rolled discarded shape.

Patent No. 6938820 Utility model registration number 3237902

However, in the absorbent article disclosed in Patent Document 1, when the absorbent article is to be disposed of, both ends of the pad body where the adhesive is provided must be folded toward the top sheet. This means that there is a risk that the person disposing of the pad body may come into contact with the top sheet when folding the pad body. Furthermore, when the pad body is rolled up and disposed of, it is generally rolled from one end in the longitudinal direction along the longitudinal direction. At this time, the person disposing of the pad body must hold down the other end in the longitudinal direction of the pad body, which may result in the person disposing of the pad body coming into contact with the top sheet even in the absorbent article disclosed in Patent Document 2.

The present invention was made with the above problem in mind, and aims to provide an absorbent article that can maintain its folded shape when discarded and that makes it difficult for the person disposing of the article to touch the top sheet.

In order to achieve the above object, the present invention provides an absorbent article that has a top sheet, a back sheet, and an absorbent body disposed between them, and that is equipped with a pad main body that extends in a longitudinal direction corresponding to the front and rear of a wearer, and an engagement portion that is provided on the outer surface of the pad main body and is capable of engaging with an outer article, and that is used by being attached to the outer article, the engagement portion being disposed at least on one end of the pad main body in the longitudinal direction and capable of engaging with the inner surface of the pad main body, and the other end of the pad main body in the longitudinal direction is provided with a pocket that covers the inner surface of the pad main body and is open toward the middle part in the longitudinal direction. A pocket sheet is provided to form a pocket portion, and the pad body has an insertion portion at one end in the longitudinal direction that can be inserted into the pocket portion when the pad body is folded in half at a folding position set in the middle portion in the longitudinal direction with the top sheet on the inside, with the middle portion in the width direction perpendicular to the longitudinal direction bent inward along the longitudinal direction, and the other end in the longitudinal direction has an enclosing portion that is bent inward along the longitudinal direction to sandwich the insertion portion when the insertion portion is inserted into the pocket portion, and at least a portion of both sides in the width direction engages with the engagement portion.

This allows the absorbent article of the present invention to maintain its folded shape when discarded, and also makes it difficult for the person disposing of the article to come into contact with the top sheet when discarding the article.

The embodiment for implementing the absorbent article according to the present invention will be described below based on Example 1 shown in the drawings. In the following description, the direction corresponding to the front and back of the wearer's body is referred to as the "longitudinal direction L", and the direction perpendicular to the longitudinal direction L is referred to as the "width direction W". Furthermore, the direction perpendicular to both the longitudinal direction L and the width direction W is referred to as the "thickness direction T". Furthermore, in the thickness direction T, the side closer to the wearer is referred to as the "inner side (skin side)" and the side closer to the outer article is referred to as the "outer side (non-skin side)".

The absorbent article 1 in Example 1 is used by being attached to the inside of an outer article such as a disposable paper diaper, incontinence pants, a diaper cover, or underwear, and is specifically known as a urine absorption pad or an incontinence pad. As shown in FIG. 1, the absorbent article 1 in Example 1 includes a pad body 10, an engagement portion 20 (see FIG. 2), and a pocket sheet 30.

The pad body 10 has a top sheet 11, a back sheet 12, and an absorbent body 13. The pad body 10 is formed by sandwiching the absorbent body 13 between the top sheet 11 and the back sheet 12, and fixing at least a suitable area including the peripheral edge portion by an adhesive such as hot melt or welding. The pad body 10 has a rectangular shape extending along the longitudinal direction L when viewed in a plan view from the thickness direction T.

The top sheet 11 is in contact with the wearer's skin when the pad body 10 is attached to the outerwear, and is made of a liquid-permeable sheet material that allows bodily fluids to pass through quickly. The sheet material constituting the top sheet 11 is preferably a nonwoven fabric with or without holes. In addition, the material fibers constituting the nonwoven fabric may be, for example, olefins such as polyethylene and polypropylene, synthetic fibers such as polyester and polyamide, regenerated fibers such as rayon and cupra, and blended fibers thereof, and natural fibers such as cotton, which may be used alone or in combination of two or more. In addition, examples of processing methods for nonwoven fabric include the spunlace method, the spunbond method, the thermal bond method, the meltblown method, and the needle punch method. Among these processing methods, the spunlace method is preferable in that it can produce a nonwoven fabric with excellent flexibility. In addition, the spunbond method is preferable in that it can produce a nonwoven fabric with excellent drapeability, and the thermal bond method is preferable in that it can produce a bulky and soft nonwoven fabric. The material fibers constituting the nonwoven fabric may be composite fibers such as core-sheath fibers, side-by-side fibers, and split fibers, in which a fiber with a high melting point is the core and a fiber with a low melting point is the sheath.

In addition, since the top sheet 11 comes into contact with the wearer's skin, the surface of the top sheet 11 becomes the surface that is used for the absorbent article 1 and is subject to soiling during use.

The back sheet 12 is in contact with the outer article when the pad body 10 is attached to the outer article, and is made of a liquid-impermeable (water-resistant) sheet material that does not allow body fluids to pass through. In other words, the sheet material constituting the back sheet 12 is preferably a liquid-impermeable plastic sheet such as polyethylene or polypropylene, a laminated nonwoven fabric in which a nonwoven fabric is laminated on the outside of a plastic sheet, or a laminated sheet of nonwoven fabric in which a waterproof film is interposed to ensure substantial liquid impermeability. In addition, the back sheet 12 may be made of a sheet material having moisture permeability from the viewpoint of preventing stuffiness. The water-impermeable/moisture-permeable sheet material may be a microporous sheet obtained by melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching the sheet in a uniaxial or biaxial direction.

The absorbent body 13 is a liquid absorbent material that absorbs and retains bodily fluids. The absorbent body 13 is composed of, for example, absorbent polymer particles and pulp fibers, and may be wrapped in a core wrap sheet (not shown) made of crepe paper, nonwoven fabric, or the like. The absorbent body 13 is formed with an outer shape smaller than the top sheet 11 and the back sheet 12, and has a shape and size that does not protrude from the top sheet 11 and the back sheet 12 in the longitudinal direction L and the width direction W. The absorbent body 13 may be a single layer or multiple layers.

Gathered sheets 14 that form three-dimensional gathers are provided on both sides of the width direction W of the pad body 10. The gathered sheet 14 is a long and narrow sheet material extending in the longitudinal direction L, and is formed, for example, of a water-repellent or liquid-impermeable nonwoven fabric. One end of the gathered sheet 14 in the width direction W is fixed to the pad body 10 by, for example, an adhesive such as hot melt or welding. The other end of the gathered sheet 14 in the width direction W is provided with an elastic stretch material 14a that can stretch in the longitudinal direction L. Here, the elastic stretch material 14a is composed of a plurality of thread-like or band-like synthetic rubbers arranged in parallel in the width direction W, and is fixed to the gathered sheet 14 in a predetermined stretched state.

The elastic stretch material 14a then contracts under its own contractile force and returns to its natural length, causing the other end of the gather sheet 14 in the width direction W to rise from the top sheet 11 toward the wearer, forming a wall-like three-dimensional gather. The three-dimensional gathers of the absorbent article 1 prevent leakage of bodily fluids from around the legs (side leakage). At both ends of the gather sheet 14 in the longitudinal direction L, the entire surface of the gather sheet 14 is adhered to the inner surface of the pad body 10 in a collapsed state.

The pad body 10 of Example 1 has an insertion portion S at one end in the longitudinal direction L (hereinafter referred to as the first end 10a) and an enclosing portion H at the other end in the longitudinal direction L (hereinafter referred to as the second end 10b). Furthermore, the pad body 10 has a fold line O1 set in the middle in the longitudinal direction L. The fold line O1 is an imaginary line that passes through the center position of the pad body 10 in the longitudinal direction L and extends in the width direction W. Note that the pad body 10 of the absorbent article 1 may be pre-folded in half as a form when it is supplied as an unused product. In this case, the fold line O1 is a line along which the pad body 10 is actually folded to form a folding habit.

The insertion portion S is an area that is inserted into the pocket portion P described below with the middle portion in the width direction W bent inward along the longitudinal direction L when the pad body 10 is folded in half at the fold line O1 with the top sheet 11 on the inside. When the insertion portion S is pinched from the outside along the center line O2, the middle portion in the width direction W is bent inward along the longitudinal direction L and stands up. When the insertion portion S is pinched from the outside along the center line O2, both ends of the insertion portion S in the width direction W maintain a flat shape extending in opposite directions. The "center line O2" is an imaginary line that passes through the center position of the pad body 10 in the width direction W and extends in the longitudinal direction L.

Furthermore, the insertion portion S of Example 1 is formed with a folding portion 15 that makes it easier to fold the pad body 10 inward along the longitudinal direction L. The folding portion 15 is formed, for example, on the inner surface or inside of the pad body 10, and is configured by a slit or embossment that extends linearly or in a broken line along the longitudinal direction L. The length X of the folding portion 15 in the longitudinal direction L can be set arbitrarily, but as shown in FIG. 2, it is preferable that it is formed so as to straddle the engagement portion 20, and it may be formed over the entire length of the pad body 10. It is also preferable that the folding portion 15 is arranged along the center line O2.

The surrounding portion H is an area that is bent inward along the longitudinal direction L when the insertion portion S is inserted into the pocket portion P, and sandwiches the insertion portion S inserted into the pocket portion P along the width direction W. When the surrounding portion H is bent inward along the longitudinal direction L, a portion of both sides in the width direction W engages with the engagement portion 20.

2, the engagement portion 20 is provided on the outer surface of the pad body 10, i.e., the surface of the back sheet 12 facing the outer article, and is arranged at the first end 10a and the second end 10b. The engagement portion 20 is a member that can engage with both the outer article and the inner surface of the pad body 10, and is not particularly limited as long as it does not damage the outer article or the wearer's skin, but is composed of, for example, a mechanical hook tape or a hot melt for preventing slippage. Also, the engagement portion 20 of Example 1 extends in a band shape along the width direction W across the center line O2, as shown in FIG. 2.

The engaging portion 20 may be provided at least at the first end 10a of the pad body 10. The engaging portion 20 may extend linearly from the first end 10a to the second end 10b along the longitudinal direction L of the pad body 10 and may be a plurality of lines arranged at a predetermined interval in the width direction W, or may be provided on the entire surface of the back sheet 12. Furthermore, three or more engaging portions 20 may be arranged at a predetermined interval along the longitudinal direction L.

The distance α along the longitudinal direction L from one edge 10c of the pad body 10 to one of the engagement parts 20 is set arbitrarily. The distance β along the longitudinal direction L from the other edge 10d of the pad body 10 to the other engagement part 20 is set to a distance at which the other engagement part 20 can engage with the surrounding part H when the surrounding part H is bent inward along the longitudinal direction L.

The pocket sheet 30 is provided at the second end 10b of the pad body 10 and is a sheet material that covers the inner surface of the pad body 10. The pocket sheet 30 is made of a liquid-impermeable (water-resistant) sheet material that does not allow bodily fluids to pass through, similar to the back sheet 12, for example.

The pocket sheet 30 has both edges 31a, 31b in the width direction W extending parallel to the longitudinal direction L, an outer edge 31c in the longitudinal direction L extending parallel to the width direction W, and an inner edge 31d in the longitudinal direction L cut out in a wedge shape around the center in the width direction W, so that it has a pentagonal shape in plan view. As shown in FIG. 3, the pocket sheet 30 is joined to the pad body 10 at the portions along both edges 31a, 31b in the width direction W and the portion along the outer edge 31c in the longitudinal direction L. The inner edge 31d in the longitudinal direction L of the pocket sheet 30 is not joined to the top sheet 11. Note that in FIG. 3, the portions where the pocket sheet 30 is joined to the pad body 10 are indicated by dots.

As a result, the pocket sheet 30 has an inner edge 31d that is not joined to the top sheet 11 as an opening edge, and forms a pocket portion P that is open toward the middle portion (fold line O1) in the longitudinal direction L of the pad body 10 (see Figures 4 and 5). In other words, the inner edge 31d in the longitudinal direction L of the pocket sheet 30 is an open edge that forms the pocket portion P.

In addition, the inner edge 31d of the pocket sheet 30 in the longitudinal direction L is cut out in a wedge shape, so that it is set at an angle so as to approach the outside in the longitudinal direction L of the pad body 10 as it moves from both ends in the width direction W toward the center of the width direction W.

The size of the pocket sheet 30 can be set arbitrarily, but it is desirable to set it to a size that forms a pocket portion P that can store the insertion portion S of the pad body 10 without any gaps. In other words, the length of the width direction W of the pocket sheet 30 is set to be shorter than the length of the width direction W of the pad body 10.

The function of the absorbent article 1 of Example 1 is explained as follows.

After use, the absorbent article 1 of Example 1 is folded in half along the fold line O1 set in the middle of the longitudinal direction L of the pad body 10 with the top sheet 11 facing inward, and then discarded. At this time, a person discarding the absorbent article 1 first grasps the insertion portion S of the pad body 10 from the outside along the center line O2. As a result, as shown in FIG. 6, the middle portion of the pad body 10 in the width direction W at the insertion portion S is bent inward along the longitudinal direction L and stands up.

Here, the insertion portion S is formed with a folding portion 15. This allows the disposer to easily fold the insertion portion S inward along the longitudinal direction L.

In addition, the middle part of the insertion part S in the width direction W stands up, but both ends in the width direction W maintain a flat shape extending in opposite directions (see FIG. 6). Therefore, when the insertion part S is pinched from the outside, it has a rectangular shape with corners G in a plan view.

Next, the discarder folds the pad body 10 in half at the fold line O1 with the top sheet 11 on the inside. Then, while holding the outside of the pad body 10, the discarder inserts the insertion portion S between the top sheet 11 and the pocket sheet 30. That is, the insertion portion S of the pad body 10 is inserted into the pocket portion P with the middle portion in the width direction W bent inward along the longitudinal direction L, as shown in FIG. 7.

Here, the pocket sheet 30 is set at an angle so that the inner edge 31d in the longitudinal direction L approaches the outside of the longitudinal direction L of the pad body 10 as it moves from both ends in the width direction W toward the center in the width direction W. Therefore, the inner edge 31d that is not joined to the top sheet 11 is widely spaced apart from the top sheet 11, allowing the pocket portion P to be exposed. As a result, the corner portion G of the insertion portion S is easily (smoothly) inserted into the pocket portion P, and the standing middle portion in the width direction W is not inserted into the pocket portion P. Therefore, the pad body 10 is provisionally fixed in a state in which interference between the standing portion of the insertion portion S and the pocket sheet 30 is avoided.

Then, after inserting the insertion portion S of the pad body 10 into the pocket portion P, the disposer presses the outside of the enclosing portion H of the pad body 10 and folds the enclosing portion H inward along the longitudinal direction L. This causes the enclosing portion H to sandwich the insertion portion S while it is inserted into the pocket portion P. At this time, as shown in FIG. 8, the inner surface of the enclosing portion H engages with the engagement portion 20 at parts of both sides in the width direction W.

As a result, in the absorbent article 1 of Example 1, the pad body 10 is temporarily fixed in a state where it is folded in half at the middle in the longitudinal direction L with the top sheet 11 on the inside. This prevents the absorbent article 1 from opening when disposed of and exposing the top sheet 11. Furthermore, the absorbent article 1 of Example 1 is less likely to have gaps between the folded pad bodies 10, which can suppress the leakage of odors and seepage of body fluids.

Furthermore, in the absorbent article 1 of Example 1, when the insertion portion S of the pad main body 10 is pinched from the outside, the middle portion of the insertion portion S in the width direction W is bent inward along the longitudinal direction L. Then, the insertion portion S is inserted into the pocket portion P while the outside is still pinched. Furthermore, the surrounding portion H of the pad main body 10 is pressed from the outside and bent inward, and parts of both ends in the width direction W engage with the engagement portion 20.

In this way, when disposing of the absorbent article 1, the disposer can pinch or press the outside of the pad body 10 to put the pad body 10 into the discarded shape. This makes it difficult for the disposer to touch the top sheet 11, which is the surface to be used, when disposing of the absorbent article 1 of Example 1.

When disposing of the absorbent article 1, the disposer first folds the pad body 10 in half along the fold line O1. After folding the pad body 10 in half, the disposer may then pinch the insertion portion S from the outside and insert the insertion portion S into the pocket portion P.

In this case, the pad body 10 is folded in half and then the insertion portion S is inserted into the pocket portion P, making it even more difficult for the disposer to touch the top sheet 11.

In addition, in the absorbent article 1 of Example 1, the inner edge 31d of the pocket sheet 30 in the longitudinal direction L is set at an angle so as to approach the outer side in the longitudinal direction L of the pad body 10 as it moves from both ends in the width direction W toward the center in the width direction W.

Therefore, when the insertion portion S is inserted into the pocket portion P, the folded and standing portion of the insertion portion S does not interfere with the pocket sheet 30. This allows the disposer to easily (smoothly) insert the insertion portion S into the pocket portion P, and also makes it difficult for the disposer to touch the top sheet 11.

In addition, in the absorbent article 1 of Example 1, the insertion portion S is formed with a fold 15 that makes it easier to fold the pad body 10 along the longitudinal direction L. As a result, when the outside of the insertion portion S is pinched by the disposer, the insertion portion S is folded starting from the fold 15. Therefore, the insertion portion S of the pad body 10 can be easily folded inward along the longitudinal direction L. This allows the disposer to easily transform the pad body 10 into a discarded shape.

The absorbent article of the present invention has been described above based on Example 1, but the specific configuration is not limited to Example 1, and design changes and additions are permitted as long as they do not deviate from the gist of the invention in each claim.

In the absorbent article 1 of Example 1, the inner edge 31d in the longitudinal direction L of the pocket sheet 30 is cut out in a wedge shape, and the inner edge 31d is set at an angle so as to approach the outside of the longitudinal direction L of the pad body 10 as it moves from both ends in the width direction W toward the center of the width direction W. However, the shape of the pocket sheet 30 is not limited to that of Example 1.

For example, as in the pocket sheet 40 provided in the absorbent article 1A of the first modified example shown in FIG. 9, the inner edge 41d in the longitudinal direction L may not be cut out. In this case, the inner edge 41d extends parallel to the width direction W, and the pocket sheet 40 has a rectangular shape in a plan view. This allows the area of the inner surface of the pad main body 10 covered by the pocket sheet 40 to be larger than that of the absorbent article 1 of Example 1. Furthermore, the absorbent article 1A of the first modified example can prevent the flow of bodily fluids from the second end 10b of the pad main body 10 outward in the longitudinal direction L by the pocket sheet 40.

In this case, as shown in FIG. 9, perforations 42 extending from the inner edge 41d in the longitudinal direction L may be formed in the middle of the pocket sheet 40 in the width direction W. The perforations 42 are formed of holes or slits arranged at regular intervals in the longitudinal direction L.

By forming the perforations 42, the pocket sheet 40 of the first modified example can be easily divided at the middle portion in the width direction W. Therefore, when the insertion portion S of the pad body 10 of the absorbent article 1A of the first modified example is inserted into the pocket portion P, the pocket sheet 40 is divided at the perforations 42. This allows the absorbent article 1A to eliminate interference between the pocket sheet 40 and the upright portion of the insertion portion S. Therefore, the insertion portion S can be inserted to an appropriate position in the pocket portion P, and the absorbent article 1A can be in a stable disposal shape.

When the pocket sheet 40 has perforations 42 formed therein, the inner edge 41d of the pocket sheet 40 does not have to extend parallel to the width direction W. The inner edge 41d may be formed, for example, in a convex curve toward the middle of the longitudinal direction L of the pad body 10.

Also, as in the absorbent article 1B of the second modified example shown in FIG. 10, an engaged member 50 that can engage with the engaging portion 20 with a force stronger than the engaging force with which the pad body 10 engages with the engaging portion 20 may be provided on the inner side of the enclosing portion H. Here, the engaged member 50 is composed of, for example, mechanical loop tape or release paper to which hot melt can be adhered. Also, the engaged member 50 may be provided on at least a portion of the inner side of the enclosing portion H that comes into contact with the engaging portion 20 when the enclosing portion H is bent inward along the longitudinal direction L.

As a result, in the absorbent article 1B of the second modified example, when the enclosing portion H is bent inward along the longitudinal direction L, the engaged member 50 can engage with the engaging portion 20. Therefore, in the absorbent article 1B of the second modified example, the enclosing portion H is less likely to come off the engaging portion 20 than in the absorbent article 1 of Example 1, and the absorbent article 1B can be temporarily fixed in the disposal shape in a stable manner.

Also, as in the absorbent article 1C of the third modified example shown in FIG. 11, the second fold 16 may be formed between the insertion portion S and the fold line O1 in the pad body 10. Here, the second fold 16 is provided between the engagement portion 20 provided in the insertion portion S and the fold line O1. The second fold 16 is structured to make it easier to fold the pad body 10 inward along the longitudinal direction L, and extends in a direction approaching the outside of the longitudinal direction L of the pad body 10 as it moves from both ends of the width direction W of the pad body 10 toward the center of the width direction W. The second fold 16, like the fold 15, is formed on the inner surface or inside of the pad body 10, and is composed of slits or embossments extending linearly or in a broken line.

In the absorbent article 1C of the third modified example, the second fold 16 is provided, so that when a disposer pinches the insertion portion S, the insertion portion S is folded starting from the second fold 16. This allows the disposer to easily transform the pad body 10 into the discarded shape.

The insertion portion S of the pad body 10 may be made more rigid than the surrounding portion H. This prevents the insertion portion S from twisting or deforming when the insertion portion S is inserted into the pocket portion P of the absorbent article 1, making it easier to insert the insertion portion S. The rigidity of the insertion portion S can be increased, for example, by increasing the rigidity of the top sheet 11 or back sheet 12 at the insertion portion S or by increasing the thickness of the absorbent body 13 compared to the surrounding portion H.

In addition, in Example 1, a fold 15 is formed in the insertion portion S, and in the third modified example, a second fold 16 is formed between the insertion portion S and the fold line O1. However, the fold 15 and the second fold 16 do not necessarily have to be formed. In addition, both the fold 15 and the second fold 16 may be formed in the pad body 10.
