Description

[Technical field]

[0001] The present invention relates to an absorbent article. [Background technology]

[0002] Absorbent articles such as disposable diapers, incontinence pads, sanitary products, etc. have been developed (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-175885 A Summary of the Invention [Problem to be solved by the invention]

[0004] For example, when an absorbent body of an absorbent article holds a certain amount of water (e.g., water contained in urine or watery stool) or more, it is considered that water will seep out from the absorbent body. Therefore, there is a possibility that water will leak from the absorbent article. Therefore, in order to replace the absorbent article before such a situation occurs, it is considered that the absorbent article is provided with an indicator containing a component that changes color depending on the pH of the water contained in urine or watery stool. However, in such a case, it is considered that the sweat of the wearer has a property of showing a pH similar to that of the water contained in urine or watery stool. Therefore, it is considered that the indicator reacts to the sweat and changes color. Therefore, it is considered that the amount of water held by the absorbent body is erroneously notified.

[0005] Therefore, an object of the present invention is to provide a technique for preventing an erroneous notification of the amount of water held by an absorbent body. [Means for solving the problem]

[0006] In order to solve the above problems, in the present invention, a groove is provided in the absorbent body, and an indication portion that is visible from the non-skin facing side is provided in a portion that overlaps with the groove in the thickness direction.

[0007] In detail, the present invention is an absorbent article comprising an absorbent body that expands when it absorbs moisture contained in the wearer's excrement, and has hole-like or concave grooves that recess from the non-skin side to the skin side, a laminate with the absorbent body as an inner layer, and an indicator portion that is provided in a part of the laminate on the non-skin side of the absorbent body, and that overlaps at least a part with the groove or a position on an extension line of the longitudinal direction of the groove, and that appears on the non-skin side when the width of the groove changes, and the indicator portion changes shape due to the appearance of the part.

[0008] In the absorbent article relating to the above-mentioned aspect, the groove may be provided in the wearer's abdomen or back, and the groove may be provided in at least the crotch area of ​​the wearer and extend in a longitudinal direction from the crotch area to the abdomen or back.

[0009] In the absorbent article relating to the above-mentioned aspect, the laminate has a sheet-like member on which the display portion is provided, and the grooves are aligned in the width direction of the absorbent article, and the grooves extend to the abdominal or back portion, or a portion of the sheet-like member penetrates the groove to form a depression when viewed from the non-skin side, and the depression may further extend to the abdominal or back portion.

[0010] In the absorbent article according to the above aspect, a part of the indication portion is formed by dividing the groove in the thickness direction. The recess may be provided in a portion that does not overlap with the abdominal portion or a portion in which the recess extending to at least one of the abdominal portion and the back portion is not formed.

[0011] In the absorbent article relating to the above-mentioned aspect, the groove may be arranged at a first interval in the longitudinal direction from a first end portion on the abdominal side of the absorbent article when worn by the wearer, and the groove may be arranged at a second interval in the width direction.

[0012] The absorbent article according to the above aspect may further comprise a first stretchable member capable of pulling the sheet-like member on a longitudinal tip side relative to the longitudinal second end of the groove outward in the width direction.

[0013] In the absorbent article relating to the above aspect, the indication portion may be displayed in a portion that overlaps with the groove, or in the depression extending to the abdomen or the back, where the portion is related to the change in the impression received by the wearer.

[0014] In the absorbent article according to the above aspect, the sheet-like members forming the recesses may be bonded to each other with a predetermined peel strength.

[0015] In the absorbent article relating to the above-mentioned aspect, a third end portion in the longitudinal direction of the groove overlaps with the indicating portion in the thickness direction, and is arranged in a stretched state in the width direction of the third end portion, and may further include a second elastic member capable of pulling an outer side portion in the width direction of the third end portion by contracting. Effect of the Invention

[0016] According to the present invention, it is possible to prevent an erroneous notification of the water retention amount of the absorbent body. [Brief description of the drawings]

[0018] Hereinafter, 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 merely examples, and the present invention is not limited to the configurations of these embodiments.

[0019] <Embodiment> In this embodiment, the longitudinal direction of a pants-type disposable diaper (an example of an "absorbent article" in the present application, hereinafter simply referred to as a "diaper") is the direction connecting the front body arranged opposite the wearer's abdomen and the rear body arranged opposite the wearer's 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), a crotch portion arranged under the wearer's crotch (opposed to the crotch). In addition, when the paper diaper is worn by a wearer (hereinafter abbreviated as "worn state"), the side facing the wearer'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.

[0020] Fig. 1 is a perspective view of the appearance of a diaper according to the present embodiment. The diaper 1 has a crotch region 1B which corresponds to the crotch region covering the pubic area of ​​a wearer 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 wearer, and a back body region 1R which is located behind the crotch region 1B and corresponds to the back body of the wearer.

[0021] In the diaper 1, a top sheet, an absorbent, a back sheet, and a cover sheet 4 are laminated in this order from the skin-facing side (this is an example of a "laminate" in the present disclosure, and only the cover sheet 4 is shown in FIG. 1). The top sheet is liquid-permeable in part or in whole. Therefore, when the diaper 1 is worn, liquid excreted from the wearer passes through the top sheet, which may come into contact with the wearer's skin. The liquid is then absorbed by the absorbent, which is disposed on the non-skin-facing side of the top sheet. Examples of materials that can be used for the top sheet include woven fabrics, nonwoven fabrics, and porous films. The top sheet may also be hydrophilic.

[0022] The absorbent body is capable of absorbing and retaining liquid and is arranged from the front body region 1F to the back body region 1R, centered around the crotch region 1B (details will be described later). The absorbent body is made of short fibers of cellulosic fibers such as pulp fibers, rayon fibers, or cotton fibers, or synthetic fibers such as polyethylene, polypropylene, or polyethylene terephthalate that have been hydrophilized, and granular absorbent resin such as SAP (Super Absorbent Polymer), which is a hydrophilic polymer with a crosslinked structure that can absorb and retain water, is held in the gaps between the short fibers. In the absorbent body, this structure is wrapped in a liquid-permeable sheet.

[0023] The cover sheet 4 may be made of a nonwoven fabric made of a liquid-impermeable thermoplastic resin to prevent leakage of excrement, for example. Examples of liquid-impermeable thermoplastic resins include polyethylene (PE) and polypropylene (PP). The cover sheet 4 is not limited to a single-layer structure, and may be a multi-layer structure having an inner cover sheet and an outer cover sheet. In addition, a face 41 (an example of a "display unit" in the present disclosure) is drawn on the front body region 1F of the cover sheet 4 (an example of a "sheet-like member" in the present disclosure) (details will be described later).

[0024] The back sheet is a sheet formed from a liquid-impermeable thermoplastic resin material to suppress leakage of excrement, similar to the cover sheet 4. The back sheet is preferably made of a material that also has moisture permeability to suppress stuffiness when worn.

[0025] The diaper 1 also has waist gathers 3 in the area surrounding the wearer's abdomen to prevent the formation of gaps between the diaper 1 and the wearer's skin that could serve as a path for liquid to flow out. The diaper 1 also has leg gathers 3BL, 3BR in the area surrounding the wearer's thighs for the same purpose. The leg gathers 3BL, 3BR and waist gathers 3 are held in close contact with the wearer's skin by the elasticity of the rubber thread. Therefore, liquid excreted from the wearer's genitals is absorbed into the absorbent body of the diaper 1 with almost no leakage from the diaper 1. The diaper 1 also has The diaper 1 is fixed to the wearer's body in such a manner that it surrounds the wearer's waist and thighs. Since the diaper 1 is fixed to the wearer's body in this manner, the wearer can stand and walk around while wearing the diaper 1.

[0026] The diaper 1 also has a tummy gather 2 on the crotch side of the waist gather 3 in the rear body region 1R. The tummy gather 2 is formed by attaching a stretched rubber thread in the width direction to a cover sheet 4, which is the exterior body of the diaper 1.

[0027] In the diaper 1 shown in Fig. 1, the front body region 1F, the crotch region 1B, and the rear body region 1R are formed separately, and these three regions are aligned in the longitudinal direction and welded together. In the diaper 1, the front body region 1F, the crotch region 1B, and the rear body region 1R may be formed integrally.

[0028] FIG. 2 is an example of a development view of the diaper 1 as viewed from the non-skin facing side. Note that in the development view, the cover sheet 4 is omitted. As shown in FIG. 2, the absorbent body 6 is provided with a slit 61 (an example of a "hole-like groove" in the present disclosure). The slit 61 extends in the longitudinal direction. Two slits 61 are provided side by side in the width direction, spaced apart by, for example, about 20 mm (an example of a "second interval" in the present disclosure). Note that the longitudinal center portion in FIG. 2 corresponds to the crotch region 1B when the absorbent body 6 is assembled into the diaper 1. The upper side in FIG. 2 corresponds to the front body region 1F, and the lower side corresponds to the back body region 1R.

[0029] The slit 61 is disposed at a distance from the end of the waist gather 3 on the front body region 1F side in the longitudinal direction. The end where the display unit is provided The distance between the end 62 of the slit 61 and the waist gather 3 is, for example, a length that allows the separation region 64 to cover the male genitalia (an example of the "first distance" in the present disclosure). Further, on the outer side of the end 62 of the slit 61 and the separation region 64 in the width direction, for example, rubber thread 63 (an example of the "first elastic member" and the "second elastic member" in the present disclosure) that forms the tummy gather 2 is provided. The rubber thread 63 is fused to the cover sheet in a state in which it is stretched in the width direction of the diaper 1. Note that a face 41 is drawn on the cover sheet that overlaps the separation region 64. Further, the rubber thread 63 is disposed at a distance from the end 62 in the width direction, but may be disposed without being spaced from the end 62. Further, an elastic sheet may be provided as an alternative member to the rubber thread 63.

[0030] In this embodiment, the waist gather 3 is mainly formed by the first contracted portion S1 formed in the first waist region RW1 and the second contracted portion S2 formed in the second waist region RW2. The waist gather 3 improves the fit of the diaper 1 around the wearer's waist by the contraction force of the first rubber threads 4F1, 4R1 and the second rubber threads 4F2, 4R2. In the first contracted portion S1 of the waist gather 3, a plurality of first rubber threads 4F1, 4R1 are arranged parallel to each other at a constant interval A1. In addition, in the second contracted portion S2 of the waist gather 3, a plurality of second rubber threads 4F2, 4R2 are arranged parallel to each other at a constant interval A2. The interval between the rubber threads here means the distance between adjacent rubber threads in the longitudinal direction of the diaper 1.

[0031] In this embodiment, the first elastic threads 4F1, 4R1 in the first waist region RW1 and the second elastic threads 4F2, 4R2 in the second waist region RW2 extend across the entire width of the cover sheet 4. Therefore, after the diaper 1 is completed, the first elastic threads 4F1, 4R1 and the second elastic threads 4F2, 4R2 form a substantially annular elastic member that goes around the waist opening. In other words, after the diaper 1 is completed, the waist gathers 3 (the first contracted portion S1, the second contracted portion S2) are formed across the entire circumference in the waist direction.

[0032] The elastic threads 63 arranged in the tummy gathers 2 are arranged parallel to one another at a constant interval A3. In this embodiment, the interval A3 between the elastic threads 63 in the tummy gathers 2 is set to a dimension larger than the interval A2 between the second elastic threads 4F2, 4R2 in the second contracted portion S2 of the waist gathers 3. This makes it easier to spread the tummy gathers 2, which come into contact with the hip bones of the wearer, than the waist gathers 3 when the waist opening is spread to put on the diaper 1.

[0033] Fig. 3 illustrates an example of an outline of changes in the shape of the cover sheet 4 of the diaper 1 before and after a wearer urinates. Fig. 3(A) shows an example of the state of the diaper 1 before urination. Fig. 3(B) shows an example of the state of the diaper 1 after urination. Fig. 3 is an example of a view of the front body region 1F of the diaper 1 worn by a wearer, as viewed from the front.

[0034] A slit 61 (see FIG. 2; not shown in FIG. 3) provided in the absorbent body 6 extends from the crotch region 1B toward the front body region 1F and the back body region 1R. The slit 61 in the absorbent body 6 overlaps a part of the face 41 attached to the front body region 1F of the cover sheet 4. More specifically, the slit 61 overlaps both ends 42 in the width direction of the lips of the face 41 (an example of "a portion related to a change in the impression received by the wearer" in this disclosure).

[0035] When such a diaper 1 is put on a wearer, the diaper 1 is tightened in the width direction by both legs of the wearer. Therefore, as shown in Fig. 3(A), the cover sheet 4 overlapping the slit 61 is wedged into the inside of the slit 61. In Fig. 3(A), the part of the cover sheet 4 overlapping the slit 61 and wedged into the inside of the slit 61 is indicated by a wedged portion 50 (an example of "a depression formed when viewed from the non-skin side by a part of a sheet-like member entering a groove" in the present disclosure) and is represented by a thick black line extending in the longitudinal direction. When a part of the cover sheet 4 is wedged into the slit 61 in this way, both ends 42 of the lips of the face 41 are difficult to see when viewed from the non-skin side.

[0036] An adhesive is applied in advance to the portions of the cover sheet 4 that form the wedges 50. Thus, the portions of the cover sheet 4 that form the wedges 50 are bonded together. The peel strength between the bonded portions of the cover sheet 4 is such that when the absorbent body 6 absorbs moisture contained in urine or watery stool, causing the absorbent body 6 to expand and the cover sheet 4 is pulled outward in the width direction, the peel strength will cause the cover sheet 4 to peel off (an example of the "predetermined peel strength" of the present disclosure).

[0037] Moreover, the region 65 located on the longitudinal extension of the bite 50 does not overlap with the slit 61. However, the region 65 is folded inward in the width direction due to the bite of the cover sheet 4. The part of the cover sheet 4 in such a folded state is called a fold 54 (an example of the "depression extending to the abdomen or the back" of the present disclosure), and is shown by a thick black line extending in the longitudinal direction in FIG. 3(A). The fold 54 depicts the eyes 56 of the face 41. Therefore, it is difficult for the wearer to see the eyes 56 of the face 41 before the absorbent body 6 absorbs urine. The parts of the cover sheet 4 forming the fold 54 may also be bonded together by the above-mentioned adhesive.

[0038] Furthermore, a separation region 64 (see FIG. 2; not shown in FIG. 3) of the absorbent body 6 that overlaps with the region 65 in the thickness direction is pulled outward in the width direction by the rubber thread 63. Thus, the region 65 of the cover sheet 4 is also pulled outward in the width direction from the crotch region 1B toward the front body region 1F. Thus, the bites 50 and the folds 54 are non-linear, as shown in FIG. 3(A).

[0039] In addition, the spaced region 64 of the absorbent body 6 covers the male genitalia. Therefore, a region 65 of the cover sheet 4 overlapping with the spaced region 64, and a region 51 of the cover sheet 4 located between the two slits 61, rise towards the non-skin-facing side in conjunction with the spaced region 64.

[0040] On the other hand, when urine excreted from the wearer is absorbed by the absorbent body 6, the absorbent body 6 swells. Therefore, the cover sheet 4 is pulled outward in the width direction in response to the swelling of the absorbent body 6. Therefore, the width of the slit 61 provided in the absorbent body 6 increases, and the depth decreases. Therefore, the bite 50 of the cover sheet 4 that was biting into the inside of the slit 61 is pulled in the width direction, and the parts that were bonded with the adhesive are peeled off. Therefore, the bite 50 is exposed on the non-skin side. Therefore, as shown in FIG. 3(B), both ends 42 of the lips of the face 41 become visible. In addition, the folds 54 formed in the area 65 are also eliminated by pulling the cover sheet 4 outward in the width direction. Therefore, the eyes 56 of the face 41 are also visible.

[0041] [Actions and Effects] With the above-described diaper 1, a person looking at the diaper 1 from the front of the front body region 1F can visually see the gradual increase in width of the lips of the face 41 as the absorber 6 absorbs urine. The person can also visually see the gradual appearance of the eyes 56 of the face 41. Thus, with the above-described diaper 1, it is possible to prevent the wearer from being informed of an erroneous amount of moisture held by the absorber 6.

[0042] According to the diaper 1 as described above, the portions of the cover sheet 4 forming the wedges 50 are bonded together by an adhesive. The peel strength between the bonded portions of the cover sheet 4 is such that the absorbent body 6 absorbs moisture contained in urine or watery stool, expands, and the cover sheet 4 is pulled outward in the width direction, causing the portions to peel off. Therefore, when the absorbent body 6 absorbs sweat of the wearer, for example, the portions of the cover sheet 4 forming the wedges 50 are prevented from peeling off. Also, there may be cases where the absorbent body 6 expands as a result of the absorption of moisture contained in urine or watery stool by the absorbent body 6, but the degree of expansion of the absorbent body 6 is not sufficient to pull the cover sheet 4. In such cases, the portions of the cover sheet 4 forming the wedges 50 are prevented from peeling off. Therefore, in these cases, the eyes 56 of the face 41 are not exposed, and it is possible to prevent the wearer from being erroneously informed that the absorbent body 6 has absorbed a large amount of moisture, even though it has only absorbed a small amount of moisture.

[0043] Furthermore, if the portion of the cover sheet 4 that forms the wedges 50 on the face 41 contains a component that changes color, for example from white to yellow depending on the pH of the wearer's urine or watery stool, it is expected that when sweat adheres to the portion of the cover sheet 4 that forms the wedges 50, the component will react with the sweat and change color. However, even in such a case, peeling between the portions of the cover sheet 4 that form the wedges 50 is suppressed, so that the discolored portion of the face 41 is suppressed from being exposed through the wedges 50. This makes it possible to suppress erroneous notification that the absorber 6 has absorbed a large amount of moisture.

[0044] Moreover, according to the above-mentioned diaper 1, when the diaper 1 is worn by a male wearer, the separated region 64 covers the male genitalia, so that the separated region 64 protrudes toward the non-skin-facing side, and as a result, the region 51 of the cover sheet 4 also rises toward the non-skin-facing side (see FIG. 3(A)). In addition, the region 51 also rises toward the non-skin-facing side when the slits 61 are pushed toward each other by the wearer's legs in the crotch region 1B. This prevents the skin-facing side of the top sheet overlapping the region 51 from coming into contact with the wearer's skin. This prevents the wearer's sweat from penetrating the region 51. Therefore, if the region of the face 41 contains a component that changes color, for example, from white to yellow depending on the pH contained in the wearer's urine or watery stool, the face 41 is prevented from changing color in response to sweat. Thus, according to the above-mentioned diaper 1, it is possible to prevent the wearer from being erroneously informed that the absorber 6 has absorbed a large amount of moisture. can.

[0045] Furthermore, with the diaper 1 as described above, the region 51 rises toward the non-skin facing side, distorting the shape of the face 41 before the absorber 6 absorbs urine. This results in a large change in the expression of the face 41 before and after urine absorption. This allows the wearer to easily recognize the degree of moisture absorption by the diaper 1.

[0046] Furthermore, according to the above-described diaper 1, the expression of the face 41 changes as the absorber 6 absorbs urine. Therefore, if the wearer is a child, the expression can attract the child's interest. Therefore, while the child's interest is directed to the face 41, the parent can smoothly change the diaper 1.

[0047] In addition, according to the diaper 1 as described above, the spaced regions 64 of the absorbent 6 and the ends 62 of the slits 61 are constantly pulled outward in the width direction by the elastic threads 63 of the tummy gathers 2 (see FIG. 2). Therefore, even when the absorbent 6 absorbs urine, the change in width of the ends 62 is suppressed. That is, it is possible to generate a region where the width of the slits 61 changes (the center in the longitudinal direction) and a region where it does not change (the ends 62). Therefore, it is possible to make the degree of the bite 50 generated in the cover sheet 4 different between the center in the longitudinal direction and the portion overlapping the ends 62. In addition, the expansion in the width direction of the spaced regions 64 according to the absorption of urine by the absorbent 6 is also suppressed. Therefore, the expression or movement of the face 41 drawn on the cover sheet 4 can be accurately controlled.

[0048] Furthermore, in the diaper 1 as described above, the indentations 50 and folds 54 formed in the cover sheet 4 are connected in a non-linear manner (see FIG. 3(A)). Therefore, a non-linear depression can be formed in the cover sheet 4 even if the slits 61 are not formed in a non-linear manner. Therefore, even if the two ends of the lips 42 and the eyes 56 are not arranged in a linear manner in the longitudinal direction as shown in FIG. 3, it is possible to create a change in the expression of the face 41 before and after the absorber 6 absorbs urine.

[0049] [First Modification] FIG. 4 illustrates an outline of a cover sheet 4A of a diaper 1A according to a first modified example. FIG. 4(A) shows an example of the state of the diaper 1A before the wearer urinates. Meanwhile, FIG. 4(B) shows an example of the state of the diaper 1A after the wearer urinates. Note that FIG. 4 is a front view of the front body region 1F of the cover sheet 4A when worn by a wearer. In the following modified examples, the folds 54 of the cover sheet 4 may or may not be formed in the embodiment. In the following modified examples, unless otherwise specified, the portions of the cover sheet 4A that form the bites 50A are not bonded together by adhesive.

[0050] In the diaper 1A according to the modified example, the absorbent body 6A has one slit 61A extending in the longitudinal direction (not shown in FIG. 4). The slit 61A is provided in the central portion in the width direction of the absorbent body 6A. In the diaper 1A, a face 41A is depicted in the front body region 1F of the cover sheet 4A. The mouth of the face 41A (an example of a portion related to a change in the impression received by the wearer in the present disclosure) overlaps with the slit 61A.

[0051] When such a diaper 1A is put on a wearer, the diaper 1A is tightened in the width direction by the wearer's legs. As a result, as shown in Fig. 4(A), a bite 50A is generated in the cover sheet 4A, which bites into the slit 61A. This makes it difficult to see the mouth of the face 41A when viewed from the non-skin facing side.

[0052] On the other hand, when the absorbent body 6A absorbs urine excreted from the wearer, the absorbent body 6A swells. As a result, the cover sheet 4A is pulled in the width direction. In addition, the slits provided in the absorbent body 6A The width of 61A becomes wider and the depth becomes shallower. Thus, the cover sheet 4A is pulled in the width direction, and the bite 50A is eliminated. Thus, the mouth 55A of the face 41A becomes visible. Thus, a person looking at the diaper 1A from the front of the front body region 1F can visually see that the mouth 55 of the face 41A gradually opens as the absorber 6A absorbs urine. Thus, the diaper 1A can achieve the same effects as the diaper 1 according to the embodiment.

[0053] [Second modified example] Fig. 5 illustrates an outline of a cover sheet 4B of a diaper 1B according to a second modified example. Fig. 5(A) shows an example of the state of the cover sheet 4B before the wearer urinates. Meanwhile, Fig. 5(B) shows an example of the state of the cover sheet 4B after the wearer urinates.

[0054] As shown in FIG. 5(A), the diaper 1B has a face 41B in the front body region 1F of the cover sheet 4B similar to that of the diaper 1A. However, in the diaper 1B, the slit 61B provided in the absorber 6B extends in the width direction of the absorber 6B, not in the longitudinal direction (not shown). The slit 61B overlaps with an opening 55B of the face 41B (an example of a "portion related to a change in the impression received by the wearer" in the present disclosure). When the wearer puts on the diaper 1B, the cover sheet 4B overlapping with the slit 61B is inserted into the slit 61B to form an indentation 50B. Therefore, the opening of the face 41B is difficult to see when viewed from the non-skin side.

[0055] According to this diaper 1B, as shown in FIG. 5(B), when the absorber 6B absorbs urine, the absorber 6B swells. Here, the cover sheet 4B is also pulled in the longitudinal direction in response to the swelling of the absorber 6B. Thus, the wedgie 50B is eliminated by being pulled in the longitudinal direction of the diaper 1B. Thus, the mouth of the face 41B becomes visible. Thus, a person looking at the diaper 1B from the front of the front body region 1F can visually see that the mouth 55B of the face 41B gradually opens as the absorber 6B absorbs urine. This diaper 1B can also achieve the same effects as the diaper 1 according to the embodiment.

[0056] [Third Modification] FIG. 6 illustrates an outline of a cover sheet 4C of a diaper 1C according to a third modified example. In the diaper 1C according to the third modified example, one slit 61C is provided in the absorbent body 6C. FIG. 6(A) and FIG. 6(B) are outline diagrams of the cover sheet 4C in the case where one slit 61C extends in the longitudinal direction of the absorbent body 6C. FIG. 6(A) is an example of the state of the cover sheet 4C before the wearer urinates. Meanwhile, FIG. 6(B) is an example of the state of the cover sheet 4C after the wearer urinates. Meanwhile, FIG. 6(C) and FIG. 6(D) are outline diagrams of the cover sheet 4C in the case where one slit 61C extends in the width direction of the absorbent body 6C. FIG. 6(C) is an example of the state of the cover sheet 4C before the wearer urinates. Meanwhile, FIG. 6(D) is an example of the state of the cover sheet 4C after the wearer urinates.

[0057] In the diaper 1 according to the embodiment, the slit 61 overlaps with a part of the face 41 in the longitudinal direction. However, in the diaper 1C according to the third modified example, the slit 61C is provided so as to cross or run vertically across the face 41C. With this type of diaper 1C, a person who views the diaper 1C from the front of the front body region 1F will get the impression that the expression of the face 41C changes significantly as the absorber 6C absorbs urine. This prevents the wearer from being notified of an erroneous amount of moisture held by the absorber 6C.

[0058] [Fourth Variation] FIG. 7 illustrates an outline of a cover sheet 4D of a diaper 1D according to a fourth modified example. The diaper 1D according to the fourth modified example has one slit 61D in the longitudinal or width direction of an absorbent body 6D, similar to the third modified example. FIGS. 7(A) and 7(B) show a single slit 61D. 7A and 7B are schematic diagrams of the cover sheet 4D when it extends in the longitudinal direction of the absorbent body 6D. FIG. 7A is an example of the state of the cover sheet 4D before the wearer urinates. Meanwhile, FIG. 7B is an example of the state of the cover sheet 4D after the wearer urinates. Meanwhile, FIG. 7C and FIG. 7D are schematic diagrams of the cover sheet 4D when one slit 61D extends in the width direction of the absorbent body 6D. FIG. 7C is an example of the state of the cover sheet 4D before the wearer urinates. Meanwhile, FIG. 7D is an example of the state of the cover sheet 4D after the wearer urinates.

[0059] In the diaper 1D according to the fourth modification, the slit 61D is provided so as to cross or run vertically across the face 41D. In addition, the face 41D is depicted in the wedges 50D of the cover sheet 4D that wedges into the slit 61D. Therefore, before urine absorption, the face 41D is not exposed to the outside (see Figs. 7(A) and 7(C)). With this type of diaper 1D, a person who sees the diaper 1D from the front of the front body region 1F will get the impression that the design of the cover sheet 4D changes significantly as the absorber 6D absorbs urine. This prevents the wearer from being notified of an erroneous amount of moisture held by the absorber 6D.

[0060] [Fifth Modification] FIG. 8 illustrates an outline of the cover sheet 4E of the diaper 1E according to the fifth modified example. In the cover sheet 4E shown in FIG. 8(A) and FIG. 8(B), a face 41E with a figure 52A added to the widthwise end of the lips is drawn on the cover sheet 4E. FIG. 8(A) is an example of the state of the cover sheet 4E before the wearer urinates. Meanwhile, FIG. 8(B) is an example of the state of the cover sheet 4E after the wearer urinates. Also, in the cover sheet 4E shown in FIG. 8(C) and FIG. 8(D), a face 41E with a figure 52B added to the cheek portion is drawn. FIG. 8(C) is an example of the state of the cover sheet 4E before the wearer urinates. Meanwhile, FIG. 8(E) is an example of the state of the cover sheet 4E after the wearer urinates.

[0061] When a person views the diaper 1E from the front of the front body region 1F, the person can visually recognize the figures 52A, 52B (see Figs. 8(B) and 8(D)) on the face 41E as the absorbent body 6E absorbs urine. This gives the impression that the facial expression of the face 41E is changing significantly. This prevents the wearer from being notified of an erroneous amount of moisture held by the absorbent body 6E.

[0062] [Sixth Modification] FIG. 9 illustrates an outline of a cover sheet 4Z of a diaper 1Z according to a sixth modified example. In the diaper 1Z according to the sixth modified example, an animal or a character is drawn on the cover sheet 4F as a substitute for the face 41. FIG. 9(A) and FIG. 9(B) are outline diagrams of the cover sheet 4Z on which an animal picture is drawn as a substitute for the face 41. FIG. 9(A) is an example of the state of the cover sheet 4Z before the wearer urinates. Meanwhile, FIG. 9(B) is an example of the state of the cover sheet 4Z after the wearer urinates. Also, FIG. 9(C) and FIG. 9(D) are outline diagrams of the cover sheet 4Z on which a character picture is drawn as a substitute for the face 41. FIG. 9(C) is an example of the state of the cover sheet 4Z before the wearer urinates. Meanwhile, FIG. 9(D) is an example of the state of the cover sheet 4Z after the wearer urinates.

[0063] In the case of the diaper 1F shown in Figures 9(A) and 9(B), the animal's torso 43 is depicted in the wedged portion 50Z of the cover sheet 4Z that is wedged into the slit 61F. The animal's tail 44 is depicted in the portion of the cover sheet 4Z that is not wedged into the slit 61Z. With such a diaper 1Z, a person looking at the diaper 1Z from the front of the front body region 1F can newly see the torso 43, which is a large part of the animal's body, as the absorbent body 6Z absorbs urine. This gives the impression that the overall shape of the animal depicted on the cover sheet 4Z has changed significantly. This results in an incorrect amount of moisture retention in the absorbent body 6Z when worn. The information is suppressed from being notified to the public.

[0064] In the case of the diaper 1Z shown in Fig. 9(C) and Fig. 9(D), the object 45 held by the character 40 is depicted in the wedged portion 50Z of the cover sheet 4Z that is wedged into the slit 61Z. With such a diaper 1Z, a person who looks at the diaper 1Z from the front of the front body region 1F can newly see the object 45 as the absorbent body 6Z absorbs urine. This gives the impression that the character 40 attached to the cover sheet 4Z has changed significantly. This prevents the wearer from being notified of an erroneous amount of moisture held by the absorbent body 6Z.

[0065] [Seventh Variation] FIG. 10 illustrates an outline of the cover sheet 4G of the diaper 1G according to the seventh modification. In the diaper 1G according to the seventh modification, two types of pictures are drawn as substitutes for the face 41. FIG. 10(A) and FIG. 10(B) are outline diagrams of the cover sheet 4G on which two character pictures are drawn as substitutes for the face 41. FIG. 10(A) is an example of the state of the cover sheet 4G before the wearer urinates. Meanwhile, FIG. 10(B) is an example of the state of the cover sheet 4G after the wearer urinates. Also, FIG. 10(C) and FIG. 10(D) are outline diagrams of the cover sheet 4G on which a pattern and a character picture are drawn as substitutes for the face 41. FIG. 10(C) is an example of the state of the cover sheet 4G before the wearer urinates. Meanwhile, FIG. 10(D) is an example of the state of the cover sheet 4G after the wearer urinates.

[0066] In the case of the diaper 1G shown in Fig. 10(A) and Fig. 10(B), a character 46A is drawn in the wedged portion 50G of the cover sheet 4G that is wedged into the slit 61G. A character 46B is drawn in a portion of the cover sheet 4G that is not wedged into the slit 61G. With such a diaper 1G, a person who looks at the diaper 1G from the front of the front body region 1F can newly see the character 46A as the absorber 6G absorbs urine. This gives the impression that the picture on the cover sheet 4G is changing significantly. This prevents the wearer from being notified of an erroneous amount of moisture held by the absorber 6G.

[0067] 10(C) and 10(D), a character 48 is drawn in a wedged portion 50G of a cover sheet 4G that wedges into a slit 61G. A pattern 47 is applied to the cover sheet 4G so as to span the wedged portion 50G in the width direction. With such a diaper 1G, a person who looks at the diaper 1G from the front of the front body region 1F has the impression that the character 48 appears from within the pattern 47 as the absorbent body 6G absorbs urine. This prevents the wearer from being notified of an erroneous amount of moisture held by the absorbent body 6G.

[0068] [Eighth Modification] 11 illustrates an outline of a cover sheet 4H of a diaper 1H according to an eighth modified example. In the diaper 1H according to the eighth modified example, letters are applied to the cover sheet 4H instead of the face 41.

[0069] More specifically, Fig. 11(A) and Fig. 11(B) are schematic diagrams of a cover sheet 4H with the letter "A" and a pattern as a substitute for a face 41. Fig. 11(A) is an example of the state of the cover sheet 4H before the wearer urinates. Meanwhile, Fig. 11(B) is an example of the state of the cover sheet 4H after the wearer urinates. Also, Fig. 11(C) and Fig. 11(D) are schematic diagrams of a cover sheet 4H with several letters "A" to "D" as a substitute for a face 41. Fig. 11(C) is an example of the state of the cover sheet 4H before the wearer urinates. Meanwhile, Fig. 11(D) is an example of the state of the cover sheet 4H after the wearer urinates.

[0070] In the case of the diaper 1H shown in FIG. 11(A) and FIG. 11(B), the letter "A" is a slit. The letter "A" is drawn in the bite 50H of the cover sheet 4H which bites into the absorbent 61H. A pattern 53 is applied across the letter "A" in the width direction. With such a diaper 1H, a person looking at the diaper 1H from the front of the front body region 1F gets the impression that the letter "A" is newly emerging from within the pattern 53 as the absorbent body 6H absorbs urine. This prevents the wearer from being informed of an erroneous amount of moisture held by the absorbent body 6H.

[0071] In the case of the diaper 1H shown in Figs. 11(C) and 11(D), the letters "A" to "D" are applied to the cover sheet 4H. Among these letters, the letter "C" is applied to the wedges 50H. With such a diaper 1H, a person looking at the diaper 1H from the front of the front body region 1F gets the impression that the letter "C" appears as the absorber 6H absorbs urine. This prevents the wearer from being notified of the wrong amount of moisture held by the absorber 6H. Instead of letters, numbers or symbols may be applied to the wedges 50H.

[0072] [Ninth Variation] Fig. 12 illustrates an outline of a cover sheet 4I of a diaper 1I according to a ninth modified example. In the diaper 1I according to the ninth modified example, a pattern is drawn on the cover sheet 4I as a substitute for a face 41. Fig. 12(A) shows an example of the state of the cover sheet 4I before the wearer urinates. Meanwhile, Fig. 12(B) shows an example of the state of the cover sheet 4I after the wearer urinates.

[0073] In the case of the diaper 1I shown in Fig. 12(A) and Fig. 12(B), the pattern 41I extending in the longitudinal direction is included in the wedged portion 50I of the cover sheet 4I wedged into the slit 61I. In such a diaper 1I, before the absorber 6I absorbs urine, the pattern 41I is not exposed to the outside. On the other hand, as the absorber 6I absorbs urine, a person looking at the diaper 1I from the front of the front body region 1F can newly see the pattern 41I. This gives the impression that the design of the front body region 1F of the cover sheet 4I has changed significantly. This prevents the wearer from being notified of an erroneous amount of moisture held by the absorber 6I.

[0074] [Tenth Modification] 13 illustrates an outline of a cover sheet 4J of a diaper 1J according to a tenth modified example. In the diaper 1J according to the tenth modified example, a pattern is provided on the cover sheet 4J instead of a face 41.

[0075] More specifically, Fig. 13(A) and Fig. 13(B) are schematic diagrams of a cover sheet 4J with a star-shaped pattern as a substitute for a face 41. Fig. 13(A) is an example of the state of the cover sheet 4J before the wearer urinates. Meanwhile, Fig. 13(B) is an example of the state of the cover sheet 4J after the wearer urinates. Also, Fig. 13(C) and Fig. 13(D) are schematic diagrams of a cover sheet 4J with a cross-shaped pattern as a substitute for a face 41. Fig. 13(C) is an example of the state of the cover sheet 4J before the wearer urinates. Meanwhile, Fig. 13(D) is an example of the state of the cover sheet 4J after the wearer urinates.

[0076] In the case of the diaper 1J shown in Figures 13(A) and 13(B), a slit 61J is provided so as to extend in the width direction of the diaper 1J. A star-shaped pattern is drawn in a recess 50J of a cover sheet 4J that is recessed into the slit 61J. A part of the star-shaped pattern is drawn so as to protrude from the recess 50J.

[0077] With such a diaper 1J, three triangular shapes can be seen before urine absorption as shown in Fig. 13(A). Then, as urine is absorbed, star-shaped shapes become visible as shown in Fig. 13(B). Therefore, to a person looking at the diaper 1J from the front of the front body region 1F, the pattern drawn on the front body region 1F of the cover sheet 4J is clearly visible. This gives the wearer the impression that the amount of moisture held by the absorbent body 6J is changing, thereby preventing the wearer from being notified of the amount of moisture held by the absorbent body 6J in error.

[0078] 13(C) and 13(D), a diaper 1J has a slit 61J extending in the width direction of the diaper 1J. A cross pattern is drawn in a wedged portion 50J of a cover sheet 4J that is wedged into the slit 61J. A part of the cross pattern is drawn protruding from the wedged portion 50J.

[0079] With such a diaper 1J, two rectangular shapes are visible before urine absorption as shown in Fig. 13(C). Then, as urine is absorbed, a cross shape becomes visible as shown in Fig. 13(D). Therefore, a person looking at the diaper 1J from the front of the front body region 1F will get the impression that the pattern drawn on the front body region 1F of the cover sheet 4J has changed significantly. This prevents the wearer from being notified of an erroneous amount of moisture held by the absorber 6J.

[0080] [Eleventh Modification] 14 illustrates an outline of a cover sheet 4K of a diaper 1K according to Modification 11. In the diaper 1K according to Modification 11, a flying character is depicted on the cover sheet 4K in place of a face 41.

[0081] More specifically, Fig. 14(A) shows an example of the state of the cover sheet 4K before the wearer urinates. Meanwhile, Fig. 14(B) shows an example of the state of the cover sheet 4K after the wearer urinates. In the case of the diaper 1K shown in Fig. 14(A) and Fig. 14(B), a slit 61K is provided so as to extend in the longitudinal direction of the diaper 1K. A flying character is drawn in the wedged portion 50K of the cover sheet 4K that is wedged into the slit 61K.

[0082] According to such a diaper 1K, before urine absorption, as shown in FIG. 14(A), a person looking at the diaper 1K from the front of the front body region 1F cannot see the character. Then, as urine is absorbed, as shown in FIG. 14(B), the character becomes visible. The character also appears to be flying. Therefore, a person looking at the diaper 1K from the front of the front body region 1F will get the impression that the form of the character drawn on the front body region 1F of the cover sheet 4K has changed significantly. This prevents the wearer from being notified of an erroneous amount of moisture held by the absorber 6K.

[0083] [Twelfth Modification] 15 shows an outline of a cover sheet 4L of a diaper 1L according to a twelfth modification. In the diaper 1L according to the twelfth modification, a plant is drawn on the cover sheet 4L instead of a face 41.

[0084] More specifically, Fig. 15(A) shows an example of the state of the cover sheet 4L before the wearer urinates. Meanwhile, Fig. 15(B) shows an example of the state of the cover sheet 4L after the wearer urinates. The diaper 1L has a plurality of slits 61L extending in the width direction. Plants are drawn on the cover sheet 4L so as to cross the slits 61L.

[0085] With such a diaper 1L, as shown in FIG. 15(A), before urine absorption, the portion of the cover sheet 4L on which the plant flowers and leaves are depicted is hidden by being embedded in the multiple slits 61L (embrace 50L). Then, as urine is absorbed, as shown in FIG. 15(B), the entire image of the plant becomes visible. Therefore, for a person looking at the diaper 1L from the front with respect to the front body region 1F, the plant depicted on the front body region 1F of the cover sheet 4L is not visible. This gives the impression that the shape has changed significantly, and therefore prevents the wearer from being notified of the wrong amount of water held by the absorbent body 6L.

[0086] [13th Variation] 16 illustrates an outline of a cover sheet 4M of a diaper 1M according to a thirteenth modified example. In the diaper 1M according to the thirteenth modified example, no face 41 is drawn in the indentation 50M of the cover sheet 4M that is indented into the slit 61M. In the diaper 1M, letters and the like are added in an area 49 of the cover sheet 4M that does not overlap with the slit 61M.

[0087] More specifically, Fig. 16(A) is a schematic diagram of a case where letters and patterns are applied to an area 49A of the cover sheet 4M between the slits 61M aligned in the width direction, and Fig. 16(B) is a schematic diagram of a case where letters and patterns are applied to an area 49B at the longitudinal tip rather than the end of the longitudinal slits 61M.

[0088] According to the diaper 1M shown in FIG. 16(A), a part of the cover sheet 4M is embedded in the slit 61M before absorbing urine (edging 50M). However, the region 49A with the letters and patterns (an example of the "part not overlapping with the groove in the thickness direction" of the present disclosure) is located between the embeddings 50M and therefore visible from the outside. Furthermore, since such region 49A is visible from the outside even after absorbing urine, the letters and patterns attached to the region 49A are continuously visible from the outside. In other words, according to such a diaper 1M, the wearer can see the letters and patterns attached to the region 49A regardless of the absorption of urine by the absorber 6M. Therefore, according to such a diaper 1M, it is useful when it is desired to display information regardless of the absorption of urine. In addition, a face 41 is drawn on the cover sheet 4M where the embedding 50M occurs, as in the embodiment and modified example, although not shown.

[0089] According to the diaper 1M shown in FIG. 16(C), the region 49B is located at a position farther away than the bite 50M of the cover sheet 4K that bites into the slit 61 before urine absorption. The fold 54 is not formed in the region 49B as in the diaper 1 according to the embodiment. Therefore, the letters and patterns on the region 49B before urine absorption are visible from the outside. The letters and patterns are also continuously visible from the outside even after urine absorption. That is, according to such a diaper 1M, the wearer can see the letters and patterns on the region 49B regardless of the absorption of urine by the absorbent 6M. Therefore, according to such a diaper 1M, it is useful when it is desired to display information regardless of the absorption of urine. The region 49B is an example of the "part that does not overlap with the groove in the thickness direction" and the "part that does not have a recess extending to at least one of the abdomen and the back" of the present disclosure. The cover sheet 4M where the bite 50M occurs has a face 41 or the like drawn on it as in the embodiment and the modified example, although not shown.

[0090] [Other variations] Instead of the slits 61, a recess recessed from the skin facing side to the non-skin facing side may extend in the longitudinal direction of the non-skin facing side of the absorbent body 6. Furthermore, the face 41 may be drawn in the crotch region 1B or the back body region 1R of the cover sheet 4. Furthermore, the face 41 is not limited to being drawn on the cover sheet 4, and may be drawn on any member that is visible from the outside.

[0091] In addition, in the embodiment, a separation region 64 is provided between the slit 61 and the waist gather 3, but the separation region 64 does not have to be provided. In other words, the slit 61 may extend to the vicinity of the waist gather 3. The slit 61 may extend from the crotch region 1B to either the front body region 1F or the back body region 1R. In addition, in the embodiment, the slit 61 and a part of the face 41 overlap, but the slit 61 and the face 41 do not overlap. The face 41 may not necessarily be drawn in its entirety at the position where the fold 54 of the embodiment is formed. The fold 54 may be formed in the back body region 1R. The number and orientation of the slits 61 are not limited to the example described above. That is, the number and orientation of the slits of the cover sheet 4 that are cut into the slits 61 are not limited to the example described above.

[0092] Also, the tummy gathers 2 may not be arranged, and instead of the tummy gathers 2, an elastic member may be provided which pulls the end 62 of the slit 61 outward in the width direction. Also, instead of the tummy gathers 2, an elastic member may be provided which pulls the spaced area 64 of the cover sheet 4 outward in the width direction. Also, a part of the rubber thread 63 forming the tummy gathers 2 may be welded to the sheet-like member (e.g., the back sheet) to which the absorbent body 6 is attached. In such a case, the rubber thread 63 and the absorbent body 6 are indirectly bonded to each other. Also, the rubber thread 63 does not have to be welded to the absorbent body 6.

[0093] The diaper 1 may be a tape-type diaper in which the rear region 1R is fixed to the front region 1F via a tape. In the above embodiment and modified example, urine is absorbed by the absorbent body, but the above diaper can achieve the same effect even when water contained in watery stool is absorbed by the absorbent body.

[0094] The embodiments and modifications disclosed above can be combined with each other. [Explanation of symbols]
