Description

The present invention relates to an absorbent article.

Absorbent articles such as disposable diapers, incontinence pads, and sanitary products have been developed (see, for example, Patent Document 1).

JP 2018-175885 A

When a user puts on an absorbent article, it is expected that the skin-contacting surface of the absorbent article will be pressed toward the non-skin-contacting surface by the user's buttocks. Therefore, if an absorbent body is placed between the skin-contacting surface and the non-skin-contacting surface, the absorbent body will shrink in the direction of pressure. This means that urine absorbed into the absorbent body may flow out from the absorbent body. This means that the outflowing urine may flow over the skin-contacting surface and adhere to the area near the anus. This means that the adhered urine may cause bedsores on the skin near the anus.

The present invention aims to provide a technology that prevents urine from adhering to the area near the anus when an absorbent article is worn by a user.

To solve the above problem, the present invention provides a secondary absorbent body wrapped in a non-permeable sheet between the anus and the main absorbent body.

In detail, the absorbent article according to one aspect of the present disclosure is an absorbent article worn between the crotch of a user, and includes a liquid-permeable top sheet, a liquid-impermeable back sheet, and a main absorbent body disposed between the top sheet and the back sheet, and is equipped with an absorbent body capable of covering at least the user's urethral opening to the anus, and a protective member provided in a portion of the absorbent body facing the user's anus, the protective member having a secondary absorbent body and a liquid-impermeable water-permeation suppressing sheet that covers the secondary absorbent body from the side of the main absorbent body.

In addition, in the absorbent article according to the above aspect, the back sheet, the main absorbent body, the secondary absorbent body, and the top sheet may be arranged in this order, and when worn by the user, a space may be formed between the underside of a portion of the protective member facing the abdomen of the user and the main absorbent body.

In the absorbent article according to the above aspect, the main absorbent body may have a slit.

In the absorbent article according to the above aspect, the main absorbent body may have a recess.

In addition, in the absorbent article according to the above aspect, the thickness of the end of the protective member on the abdomen side of the user when worn by the user may gradually become thinner as it moves toward the abdomen.

In addition, in the absorbent article according to the above aspect, the underside of the end portion may be provided with a plurality of protrusions arranged in the width direction, protruding toward the main absorbent body and extending from the user's back side to the abdomen side.

In the absorbent article according to the above aspect, the water-permeation suppression sheet may have an opening that faces the anus of the user when the absorbent article is worn by the user.

In the absorbent article according to the above aspect, the thickness of the main absorbent body may be substantially the same in a portion of the main absorbent body where the protective member overlaps and in the abdominal region of the portion.

In addition, in the absorbent article according to the above aspect, the top sheet may have a contact portion that can contact the skin at a position that overlaps with an end of the protective member on the abdominal side of the user when the top sheet is worn by the user.

In addition, in the absorbent article according to the above aspect, when worn by the user, the end of the auxiliary absorbent body on the abdominal side of the user may have a portion closer to the skin side than the end of the auxiliary absorbent body on the back side of the user.

In addition, in the absorbent article according to the above aspect, when worn by the user, the end of the secondary absorbent body on the abdominal side of the user may contain more granular absorbent material than the end of the secondary absorbent body on the dorsal side of the user.

The absorbent article according to the above aspect may also have gathers that extend in the width direction when viewed from the end of the protective member on the abdominal side of the user when worn by the user.

The present invention can prevent urine from adhering to the area near the anus when the absorbent article is worn by the user.

FIG. 1 is a perspective view of a diaper according to an embodiment. FIG. 2 is a detailed view of an example of the protective material. FIG. 3 is an example of a cross-sectional view of the urine pad cut in the longitudinal direction. FIG. 4 shows an example of a cross-sectional view of a diaper according to the second embodiment.

Below, absorbent articles according to embodiments of the present invention will be described with reference to the drawings. Note that the configurations of the following embodiments are examples, and the present invention is not limited to the configurations of these embodiments.

First Embodiment
In this embodiment, the longitudinal direction of the tape-type disposable diaper is the direction connecting the front body arranged opposite the abdomen of the user and the rear body arranged opposite the back. Between the front body (one side in the longitudinal direction) and the rear body (the other side in the longitudinal direction) (the center in the longitudinal direction), the crotch part is located under the crotch of the user (opposed to the crotch). In addition, when the paper diaper is worn by the user (hereinafter abbreviated as "worn state"), the side facing the user's skin (the inner side when worn) is the skin-facing side, and the opposite side of the skin-facing side (the outer side when worn) is the non-skin-facing side. Furthermore, the direction connecting the skin-facing side and the non-skin-facing side is the thickness direction, and the direction perpendicular to both the longitudinal direction and the thickness direction is the width direction. In addition, the view from the thickness direction is the planar view.

1 is a perspective view of a diaper according to this embodiment. The diaper 1 has a crotch region 1B, which is a region corresponding to the crotch region that covers the user's pubic area when worn, a front body region 1F, which is located in front of the crotch region 1B and corresponds to the front body of the user, and a back body region 1R, which is located behind the crotch region 1B and corresponds to the back body of the user. Tapes 2L and 2R that can be attached to a front patch 2F provided on the non-user side surface of the front body region 1F are provided on both left and right edges of the back body region 1R. Thus, when the tapes 2L and 2R are attached to the front patch 2F with the front body region 1F positioned on the user's abdomen and the back body region 1R positioned on the user's back, the diaper 1 is fixed to the user's body in a state that surrounds the user's abdominal circumference and thighs. Since the diaper 1 is fixed to the user's body in this manner, the user can stand and walk while wearing the diaper 1.

In the diaper 1, an absorbent capable of absorbing and retaining liquid is mainly arranged around the crotch region 1B. The diaper 1 also includes a urine pad 10 (an example of an "absorbent article" in the present disclosure) that has an absorbent (an example of an "absorbent body" in the present disclosure) inside, separate from the absorbent. The urine pad 10 is detachable from the main body of the diaper 1, and is arranged from the front body region 1F to the rear body region 1R. By arranging the urine pad 10 in this manner, the user's urethral opening to the anus is covered by the urine pad 10. Therefore, urine excreted by the user is absorbed by the urine pad 10. In addition, since the urine excreted by the user is mainly absorbed by the urine pad 10, the user may adopt a usage method in which the urine pad 10 is changed several times a day and the diaper 1 main body is changed once every few days.

In addition, in order to prevent the formation of gaps between the diaper 1 and the user's skin that could serve as a path for liquid to escape, the diaper 1 is provided with three-dimensional gathers 3BL, 3BR in the areas surrounding the user's thighs, and a waist gather 3R in the area surrounding the user's abdominal circumference. The three-dimensional gathers 3BL, 3BR and the waist gather 3R are fitted closely to the user's skin by the elasticity of the rubber thread. Therefore, liquid discharged from the user's genitals is absorbed by the absorbent body of the diaper 1 (the absorbent body of the diaper 1 body and the urine pad 10) with almost no leakage from the diaper 1.

Figure 2 is an example of a detailed view of the protective material 11 (an example of the "protective member" of this disclosure) provided inside the urine pad 10. Figure 2(A) is an example of a front view of the protective material. Figure 2(B) is an example of a side view of the protective material 11. Figure 2(C) is an example of a back view of the protective material 11.

The protective material 11 as shown in FIG. 2 is a rectangular parallelepiped shape with a depth of about 50 mm and a width of about 50 mm. The protective material 11 has an absorbent body 12 (an example of a "secondary absorbent body" in this disclosure) inside. The absorbent body 12 holds granular absorbent resin such as SAP (an example of an "absorbent material" in this disclosure). In addition, one end 17 in the longitudinal direction of the absorbent body 12 contains more absorbent resin than the other end 18. Therefore, the height of the end 17 is higher than the height of the end 18.

More specifically, the absorbent body 12 has a structure in which granular absorbent resin such as SAP (Super Absorbent Polymer), a hydrophilic polymer with a cross-linked structure that can absorb and retain water, is held in the gaps between short fibers of cellulosic fibers such as pulp fibers, rayon fibers, or cotton fibers, or short fibers that have been hydrophilically treated synthetic fibers such as polyethylene, polypropylene, or polyethylene terephthalate. Therefore, in the absorbent body 12, the volumetric change of the absorbent resin before and after absorbing liquid basically occurs within the short fibers that hold the absorbent resin in the gaps.

In this embodiment, SAP particles refer to a resin composition containing SAP in a granular form. The term "resin composition containing SAP" as used herein is a concept that encompasses both a composition consisting of SAP alone and a composition that contains SAP as the main component and contains other substances to the extent that they do not adversely affect water absorption. Examples of "other substances" include additives (such as surface modifiers added to make the particle surface hydrophobic), unreacted monomers remaining during the synthesis of SAP, etc.

The protective material 11 also includes a nonwoven fabric 14 that is permeable to liquid. The nonwoven fabric 14 is arranged to sandwich the absorbent body 12 in the thickness direction. Therefore, urine adhering to the nonwoven fabric 14 arranged on the upper surface of the absorbent body 12 passes through the nonwoven fabric 14 and is absorbed by the absorbent body 12.

The protective material 11 also includes a waterproof film 15 (an example of a "water-permeability suppressing sheet" in the present disclosure) that covers the absorbent 12 and the nonwoven fabric 14. The waterproof film 15 has the property of suppressing the permeation of liquid. The waterproof film 15 covers the absorbent 12 and the nonwoven fabric 14, but has an opening on the upper surface (opening 20). As shown in FIG. 2(B), the waterproof film 15 has a shape in which the thickness of the portion covering the end 17 and the portion covering the end 18 gradually decreases toward the tip when viewed from the side. A rib 16 (an example of a "protrusion" in the present disclosure) is provided on the lower surface 19 of the portion covering the end 17. The rib 16 is convex downward from the lower surface 19. As shown in FIG. 2(C), a plurality of ribs 16 are provided side by side in the width direction.

3 is an example of a cross-sectional view of the urine pad 10 cut in the longitudinal direction. As shown in FIG. 3, the urine pad 10 has a back sheet 5, an absorbent 6 (an example of the "main absorbent" of the present disclosure), a protective material 11, and a top sheet 7, which are laminated in this order. The back sheet 5 and the top sheet 7 are both sheet-like members having an approximately rectangular appearance. The back sheet 5 is a sheet formed of a liquid-impermeable thermoplastic resin material to suppress leakage of excrement. The top sheet 7 is a sheet-like member that is placed on the skin side of the user so as to cover the water-absorbing surfaces of the absorbent 6 and the protective material 11. This top sheet 7 is liquid-permeable in part or all of it. Therefore, when the urine pad 10 is attached to the diaper 1, the liquid excreted by the user enters in the direction of the absorbent 6 through the top sheet 7 that may come into contact with the user's skin. For example, woven fabric, nonwoven fabric, and porous film can be used as the material for the top sheet 7. Additionally, the top sheet 7 may be hydrophilic.

The absorbent body 6 has a length that can cover the user's urethral opening to the anus in the longitudinal direction when the urine pad 10 is worn by the user. The absorbent body 6 is in a two-layer state on the back sheet 5. That is, the absorbent body 6A is placed on the back sheet 5, and the absorbent body 6B is placed on top of that. The absorbent body 6 has the same properties as the absorbent body 12. The absorbent bodies 6A and 6B are approximately uniform in thickness. The absorbent body 6B has a slit 13 in the width direction as shown in FIG. 3.

The protective material 11 is provided between the absorbent 6B and the top sheet 7. The protective material 11 is arranged so that the end 17 faces the user's abdomen when the urine pad 10 is attached to the diaper 1. The protective material 11 is arranged so as to cover a part of the opening of the slit 13 in the absorbent 6B.

When attached to the diaper 1, the back sheet 5, absorbent body 6, and top sheet 7 all extend from the front body region 1F to the rear body region 1R. Thus, both longitudinal ends of the back sheet 5, absorbent body 6, and top sheet 7 are located on the user's ventral side and back side. In other words, the user's genitals are covered by the absorbent body 6 from the user's ventral side to the back side. Therefore, whether the user excretes liquid in a ventral or backside position, the excreted liquid will enter the location of the absorbent body 6 via the top sheet 7.

(Example of use)
The urine pad 10 as shown in Fig. 3 is attached to the diaper 1 so that the protective material 11 covers the anus of the user. When the urine pad 10 is attached and used in this manner, at least a part of the tip portion 22 (an example of the "contact portion" of the present disclosure) of the top sheet 7 located closer to the user's abdomen than the protective material 11 comes into contact with the user's skin. Thus, urine excreted from the user's urethral opening and flowing on the top sheet 7 is prevented from flowing into the contact portion 21 of the top sheet 7 that comes into contact with the skin near the anus. Thus, urine is prevented from adhering to the skin near the anus, and as a result, the occurrence of bedsores is prevented.

In addition, because the lower part of the tip 22 toward the abdomen is hollow, when the user puts on the urine pad 10, the abdominal side of the tip 22 sinks toward the cavity, creating a step between the tip 22 and the contact part 21. This step also prevents urine flowing over the tip 22 from flowing onto the contact part 21.

As shown in FIG. 3, even if urine flowing on the top sheet 7 flows from the tip 22 into the contact portion 21, the protective material 11 is located below the contact portion 21. The waterproof film 15 on the upper surface of the protective material 11 is open, exposing the nonwoven fabric 14. Therefore, urine that flows onto the contact portion 21 permeates into the contact portion 21 and then into the nonwoven fabric 14. The urine then permeates into the absorbent 12 via the nonwoven fabric 14 and is absorbed by the absorbent 12. It is assumed that only a small amount of urine is absorbed by the absorbent 12 in this way.

As described above, urine flowing over the top sheet 7 is prevented from flowing onto the contact portion 21, and therefore its penetration into the top sheet 7 is promoted in the abdominal region rather than the tip portion 22. The urine that has penetrated into the top sheet 7 then enters the region where the absorbent 6 is arranged. Here, the absorbent 6B has slits 13, so the urine that has entered diffuses within the slits 13. Thus, the urine is absorbed throughout the absorbents 6A and 6B. Thus, a large amount of urine is absorbed into the absorbents 6A and 6B.

The waterproof film 15 covering the end 17 gradually becomes thinner toward the user's abdomen, and the underside 19 is provided with ribs 16. The shape of the waterproof film 15 and the ribs 16 guide urine downward into the slits 13. Thus, urine is absorbed throughout the entire absorbent bodies 6A and 6B.

As shown in FIG. 3, the absorbents 6A and 6B have a substantially uniform thickness. A protective material 11 is placed on the absorbent 6B, and the protective material 11 is covered with a waterproof film 15 except for an upper opening 20. Thus, the protective material 11 acts as a wall in the longitudinal direction. This prevents urine that has entered from the abdominal direction from returning to the top sheet 7. This prevents urine from adhering to the skin near the anus and from being absorbed by the absorbent 12 through the opening 20.

In addition, the height of the end 17 is higher than the height of the end 18. Therefore, the protective material 11 functions as a wall against urine proceeding from the side direction (abdominal direction) of the protective material 11 toward the protective material 11. Therefore, urine is prevented from returning to the top sheet 7 side. Therefore, urine is prevented from adhering to the skin near the anus and from being absorbed by the absorbent body 12 through the opening 20. In addition, as described above, the end 17 of the absorbent body 12 contains more absorbent resin than the other end 18. Therefore, when the absorbent resin absorbs urine, the absorbent resin expands, and the height of the end 17 becomes even higher than the height of the end 18. As a result, the effect of the protective material 11 as a wall is enhanced.

It is also considered that the protective material 11 is compressed in the thickness direction by the user's buttocks. Therefore, it is considered that the area of the slit 13 narrows, and urine that has flowed into the slit 13 moves toward the top sheet 7. However, the protective material 11 is provided so as to cover a portion of the slit 13. Furthermore, the protective material 11 is covered by the waterproof film 15 except for the opening 20. Therefore, the protective material 11 acts as a wall, and urine is prevented from passing through the waterproof film 15 and moving toward the top sheet 7. Therefore, urine is prevented from adhering to the skin near the anus and from being absorbed by the absorbent body 12 through the opening 20.

In addition, it is considered that the absorbent 6A or 6B provided below the protective material 11 will shrink as the protective material 11 is compressed in the thickness direction. Therefore, it is considered that urine will flow out from the absorbent 6A or 6B. However, the protective material 11 is provided on top of the absorbent 6A and 6B. Furthermore, the protective material 11 is covered with the waterproof film 15 except for the opening 20 on the upper surface. Therefore, the protective material 11 acts as a wall, and urine is prevented from passing through the waterproof film 15 and moving in the direction of the top sheet 7. Therefore, urine is prevented from adhering to the skin near the anus and from being absorbed by the absorbent 12 through the opening 20.

(Action and Effect)
According to the urine pad 10 as described above, a large amount of urine is absorbed by the absorbent 6 (6A and 6B). On the other hand, the amount of urine absorbed by the absorbent 12 can be suppressed. Therefore, even if the protective material 11 is pressed by the buttocks, the amount of urine flowing out from the absorbent 12 can be suppressed. Therefore, adhesion of urine to the skin near the anus is suppressed. Therefore, the occurrence of bedsores on the skin is suppressed.

In addition, when the protective material 11 is compressed by the buttocks and the absorbent 6 (6A and 6B) contracts in the compression direction, the absorbent 12 contains a large amount of urine, so urine flows out of the absorbent 12. The volume of the slit 13 also shrinks, so the urine in the slit 13 overflows. However, the protective material 11 is provided so as to cover a part of the slit 13. The protective material 11 is covered by the waterproof film 15 except for the opening 20. Therefore, the protective material 11 acts as a wall, and urine is prevented from passing through the waterproof film 15 and moving toward the top sheet 7. Therefore, urine is prevented from adhering to the skin near the anus, and as a result, the occurrence of bedsores is prevented. Alternatively, urine is prevented from being absorbed by the absorbent 12 through the opening 20 of the protective material 11. Therefore, a large amount of urine is prevented from being absorbed by the absorbent 12. Therefore, even when the protective material 11 is compressed by the buttocks, the amount of urine flowing out of the absorbent 12 can be reduced. This also prevents urine from adhering to the skin near the anus, and therefore prevents the development of bedsores on the skin.

In addition, according to the diaper 1 described above, the top sheet of the diaper 1 or the top sheet 7 of the urine pad 10 covers both the urethral opening and the anus of the user to receive excrement, whereas the protective material 11 is placed in a specific part of the diaper 1 or the urine pad 10 so as to perform a function specific to that specific part, such as protecting the anus.

Second Embodiment
4 shows an example of a cross-sectional view of a diaper 1C according to the second embodiment. The diaper 1C according to the second embodiment does not include an incontinence pad 10. The diaper 1C also includes a protective material 11C, which is placed on a top sheet 7C of the diaper 1C. The diaper 1C and the protective material 11C are an example of an "absorbent article" according to the present disclosure.

More specifically, the diaper 1C has a back sheet 5C, an absorbent 26 (26A, 26B, an example of the "absorbent body" and "main absorbent" of the present disclosure), a protective material 11C, and a top sheet 7C, which are laminated in this order. The back sheet 5C and the top sheet 7C are both sheet-like members having a substantially rectangular appearance. The back sheet 5C is a sheet formed of a liquid-impermeable thermoplastic resin material to suppress leakage of excrement. The top sheet 7C is a sheet-like member that is placed on the user's skin side so as to cover the water-absorbing surface of the absorbent 26 (26A, 26B). This top sheet 7C is liquid-permeable in part or in its entirety. Therefore, liquid excreted from the user enters in the direction of the absorbent 26 (26A, 26B) through the top sheet 7C that may come into contact with the user's skin. For example, a woven fabric, a nonwoven fabric, or a porous film can be used as the material for the top sheet 7C. Additionally, the top sheet 7C may be hydrophilic.

The protective material 11C is fixed onto the top sheet 7C so that the end portion 17C is located on the abdominal side of the user. Although not shown, a fixing member such as double-sided tape (an example of the "fixing portion" of this disclosure) is provided on the underside of the protective material 11C. The top sheet 7C and the protective material 11C are then fixed via the double-sided tape.

When attached to the diaper 1C, the back sheet 5C, the absorbent 26 (26A, 26B), and the top sheet 7C all extend from the front body region 1F to the rear body region 1R. Thus, both longitudinal ends of the back sheet 5C, the absorbent 26 (26A, 26B), and the top sheet 7C are located on the user's ventral and dorsal sides. In other words, the user's genitals are covered by the absorbent 26 (26A, 26B) from the user's ventral to dorsal sides. Therefore, whether the user is in a ventral or dorsal position when excreting liquid, the excreted liquid will enter the location of the absorbent 26 (26A, 26B) via the top sheet 7.

(Examples of use and effects)
The protective material 11C as shown in Fig. 4 can be attached to the top sheet 7C so as to cover the user's anus. When the protective material 11C is attached and used in this manner, at least a part of the tip portion 24 of the nonwoven fabric 14C located toward the user's abdomen from the opening 20C comes into contact with the user's skin. Thus, urine excreted from the user's urethral opening and flowing on the top sheet 7C is prevented from flowing into the contact portion 23 of the nonwoven fabric 14C that comes into contact with the skin near the anus. Thus, urine is prevented from adhering to the skin near the anus, and as a result, the occurrence of bedsores is prevented.

In addition, the protective material 11C is arranged in a convex shape on the top sheet 7C. Furthermore, the height of the end 17C is higher than the height of the end 18C. Therefore, the protective material 11C functions as a wall against urine flowing from the side direction (toward the abdomen) of the protective material 11C toward the protective material 11C. This prevents urine flowing through the top sheet 7C from climbing over the side of the protective material 11C and reaching the vicinity of the anus.

This prevents urine from adhering to the skin and from being absorbed by the absorbent 12C through the opening 20C. As described above, the end 17C of the absorbent 12C contains more absorbent resin than the other end 18C. Therefore, when the absorbent resin absorbs urine, the absorbent resin expands, making the height of the end 17C even higher than the height of the end 18C. This enhances the effectiveness of the protective material 11C as a wall. This prevents urine from adhering to the skin near the anus, and as a result, prevents the development of bedsores.

In addition, three-dimensional gathers 3BL, 3BR are arranged near the end 17C, and the three-dimensional gathers 3BL, 3BR prevent urine from flowing out in the width direction. Therefore, it is expected that the amount of urine flowing on the top sheet 7C will increase. However, even if the amount of urine flowing on the top sheet 7C is large, the protective material 11C has an increased effect as a wall, so that urine is prevented from adhering to the skin near the anus.

The waterproof film 15C covering the end 17C is gradually thinner toward the user's abdomen, and the underside 19C is provided with ribs 16C. The shape of the waterproof film 15C and the ribs 16C guide urine to permeate the top sheet 7C. Thus, the urine is guided to be absorbed by the absorbent 26 (26A, 26B).

As shown in FIG. 4, even if urine flowing on the top sheet 7C flows from the tip 24 into the contact portion 23, the urine penetrates into the absorbent body 12C through the contact portion 23 and is absorbed by the absorbent body 12C. This prevents the skin near the anus from becoming wet. This prevents the development of bedsores.

It is also possible that the absorbent 12C of the protective material 11C will be compressed in the thickness direction by the user's buttocks. However, since it is assumed that only a small amount of urine is absorbed in the absorbent 12C, urine is prevented from leaking out of the absorbent 12C even if the absorbent 12C contracts. This prevents the skin near the user's anus from becoming wet. This prevents the development of bedsores.

In addition, contraction of the absorber 12C suppresses contraction of the absorber 26 (26A, 26B). This prevents urine absorbed in the absorber 26 (26A, 26B) from seeping out onto the top sheet 7C. This reduces the possibility of urine moving to the vicinity of the anus. Even if urine flows out from the absorber 26 (26A, 26B) onto the top sheet 7C, the protective material 11C is fixed, so that the urine is prevented from passing through the waterproof film 15C and reaching the vicinity of the anus. This prevents urine from adhering to the skin near the anus, and as a result, the occurrence of bedsores is suppressed.

Furthermore, the effects of the first embodiment are also achieved in the second embodiment, unless there is a contradiction.

<Other Modifications>
The protective material 11 in the first embodiment may be fixed on the urine pad 10. The protective material 11C in the second embodiment may be provided on the lower part of the top sheet 7C and on the upper part of the absorbent 26B. A recess may be provided in the absorbent 6B instead of the slit 13. The slit 13 may not be provided. The shape of the waterproof film 15 may not be such that the thickness of the part covering the end 17 and the part covering the end 18 gradually decreases toward the tip. The rib 16 may not be provided. The opening 20 may not be provided. The thickness of the absorbent 6A and 6B may not be uniform. The amount of SAP contained in the end 17 and the end 18 may be approximately the same, and the height of the end 17 and the end 18 may be approximately the same.

The embodiments and variations disclosed above can be combined with each other.
