[0009] In the present specification and the accompanying drawings, at least embodiments [1] to
[16] are disclosed.
[0010] [1] An absorbent article configured to be attachable to a pet wearable body having a defecation hole formed therein for passing feces, a surface sheet disposed on the skin side of the pet; a back sheet disposed on the non-skin-facing side opposite the skin-facing side; an absorbent body having an absorbent core disposed between the top sheet and the back sheet, the main body portion has at least one protrusion protruding outward along the first direction from at least one end of the absorbent core in the first direction, An absorbent article in which at least one of the protrusions is located inside the ends on both sides of the main body portion in a second direction perpendicular to the first direction, includes a center line of the main body portion along the first direction, and has a first portion that can be bent independently.
[0011] In the absorbent article, at least one protruding portion has a first portion formed inward in the second direction from both ends of the main body portion, including a center line of the main body portion along the first direction, and capable of being folded independently. This allows the first portion to be folded back onto the non-skin-facing side through the defecation hole of the garment when the main body portion is attached to the garment, for example. As a result, at least a portion of the opening edge of the defecation hole can be covered. This prevents feces from adhering to the garment during defecation.
[0012] [2] The absorbent article of [1], wherein a first joining portion for attaching the first portion to the wearing body is formed on the non-skin-facing surface of the first portion.
[0013] In the above configuration, for example, the first portion that passes through the defecation opening of the garment and is folded back to the non-skin-facing side can be attached to the non-skin-facing surface of the garment by the first joining portion in the attached state. This prevents the first portion from shifting relative to the garment. In addition, in this case, a portion of the non-skin-facing surface of the garment is reliably covered by the first portion, more effectively preventing feces from adhering to the garment.
[0014] [3] The absorbent article of [1], wherein no joining portion for attaching the first portion to the wearing body is formed on the non-skin-facing surface of the first portion.
[0015] In the above configuration, since the first portion is not joined to the wearing body when the pet is worn, for example, when the pet sits on the floor, the first portion can be folded toward the inside of the defecation hole so as to face the pet's anus. This prevents the surface of the first portion on which feces adheres from facing the floor when the pet sits on the floor, for example. As a result, feces can be prevented from adhering to the floor.
[0016] [4] Of the three regions that divide the main body into three equal parts in the first direction, the region located in the center is defined as a central region, and the regions other than the central region are defined as outer regions. At least one second joining portion for attaching the main body portion to the wearing body is formed on the non-skin-facing surface of the outer region, The absorbent article of any one of [1] to [3], wherein the central region does not have a joining portion for attaching the main body portion to the wearing body.
[0017] In the above configuration, the main body portion can be attached to the garment by the second joining portion. This prevents the main body portion from shifting relative to the garment. Furthermore, no joining portion for attaching the main body portion to the garment is formed in the central region of the main body portion. In this configuration, for example, the central region of the main body portion is not joined to the garment when attached. This prevents the main body portion from losing its shape in response to movement of the garment when worn, thereby preventing urine leakage from the main body portion. Furthermore, this prevents a gap from forming between the main body portion and the garment in the region near the first portion due to the loss of shape of the main body portion. As a result, it prevents the first portion from getting into the gap and feces from getting between the main body portion and the garment.
[0018] [5] The absorbent article of [4], wherein the second joint portion is formed at least on both side portions of the at least one protrusion adjacent to both sides of the first portion in the second direction.
[0019] In the above configuration, the second joining portions are formed at least in portions adjacent to both sides of the first portion, thereby making it possible to prevent the first portion from shifting position relative to the wearing body when worn.
[0020] [6] The main body portion has a pair of side sheets for forming leak-proof gathers configured to stand up by an elastic member that contracts in the first direction, The absorbent article of [4] or [5], wherein the fixed end of the elastic member is located more inward than the inner end of the second joint in the first direction.
[0021] In the above configuration, the fixed end of the elastic member is located inside the inner end of the second joint portion in the first direction, so that the contractile force of the elastic member is not generated in the area where the second joint portion is formed. This prevents the second joint portion from losing its shape due to the contractile force of the elastic member. As a result, the fit between the main body portion and the garment can be improved.
[0022] [7] An absorbent article according to any one of [1] to [6], wherein the distance in the first direction between at least one end of the absorbent core and a base end which is the starting point of the fold of the first portion is 25 mm or less.
[0023] In the above configuration, by setting the distance between the end of the absorbent core and the base end of the first portion to 25 mm or less, the absorbent core extends to the vicinity of the defecation hole when worn. This allows the absorbent core to easily cover the urethral opening, even in pets (e.g., female dogs) whose urethral opening and anus are close together when worn, thereby preventing urine leakage from the defecation hole during urination. Even if loose stool gets into the skin-facing side of the main body portion, the loose stool can be prevented from spreading between the pet and the main body portion. Furthermore, even if the absorbent core becomes heavy due to the absorption of urine when worn and the main body portion sags, the absorbent core extending to the vicinity of the defecation hole effectively prevents urine leakage due to misalignment of the urethral opening.
[0024] [8] The at least one protrusion has a pair of protrusions protruding outward along the first direction from each end of the absorbent core on both sides in the first direction, The absorbent article according to any one of [1] to [7], wherein the first portion is provided on each of the pair of protrusions.
[0025] In the above configuration, a first portion is provided on each of the pair of protrusions. As a result, for example, when attaching the main body to the garment, the first portion can be passed through the defecation hole and folded back regardless of which end of the main body is attached with the ventral or dorsal side facing up. This eliminates the need to check the attachment direction of the main body to the garment.
[0026] [9] The absorbent article of any one of [1] to [7], wherein the first portion is provided only on one end of the main body portion in the first direction.
[0027] In the above configuration, the first portion is provided on only one end of the main body portion in the first direction, which allows the user to easily confirm, for example, that the side on which the first portion is provided is the back side when attaching the main body portion to a garment.
[0028]
[10] An absorbent article according to any one of [1] to [9], wherein the end portions on both sides of the absorbent core in the second direction include curved portions that curve closer to each other as they move inward in the first direction.
[0029] With the above configuration, the fit of the main body to the pet's legs can be improved when the absorbent core is worn, thereby preventing urine leakage from the main body and preventing the pet from feeling uncomfortable when wearing the absorbent core due to the ends of the absorbent core touching the pet's legs.
[0030]
[11] The absorbent article of
[10] , wherein the curved portion is formed in at least a central region of three regions that divide the main body portion into three equal parts in the first direction.
[0031] With this configuration, the curved portion can be positioned appropriately relative to the pet's legs when the collar is worn, thereby effectively preventing urine leakage from the main body and preventing the pet from feeling uncomfortable when wearing the collar.
[0032]
[12] The absorbent article of any one of [1] to
[11] , wherein the first portion is a convex portion that protrudes outward in the first direction more than both side portions adjacent to both sides of the first portion in the second direction.
[0033] In the above configuration, the first portion protrudes outward from the end of the main body, allowing the user to easily recognize the position of the first portion.
[0034]
[13] The first portion is formed at one end of the main body in the first direction, The absorbent article of
[12] , wherein a recess having a shape corresponding to the first portion is formed at the other end of the main body portion in the first direction.
[0035] In the above configuration, a recess is formed having a shape corresponding to the first portion (protrusion) formed at one end of the main body portion. This allows, for example, when manufacturing multiple main body portions from a continuous sheet material, to simultaneously form the recess of one adjacent main body portion along the cutting line that forms the first portion of the other main body portion. As a result, waste material generated during the formation of the first portion can be reduced, and manufacturing costs can be kept low. Furthermore, providing the recess reduces the rigidity of the main body portion in the second direction. This allows the main body portion to more easily deform in the second direction, making it easier to conform to the pet's legs, for example, between the pet's legs. As a result, it is possible to reduce the pet's discomfort when wearing the product.
[0036]
[14] The at least one protruding portion has a pair of notches formed therein, the notches extending inward from an outer end of the protruding portion in the first direction and aligned in the second direction; The absorbent article according to any one of [1] to
[11] , wherein the first portion is a portion of the at least one protruding portion that is formed between the pair of slits.
[0037] In the above configuration, for example, when manufacturing a plurality of main body portions from a continuous sheet material, the first portion can be formed by a relatively simple process of forming a pair of slits in the protruding portion. This reduces the effort required to form the first portion compared to forming a first portion with a complex shape. When attached, the portions adjacent to both sides of the first portion protrude toward the inside of the defecation hole so as to cover portions of the edge of the opening of the garment that are different from the portion covered by the first portion. This effectively prevents feces from adhering to the garment, even if, for example, the pet's anus is misaligned with the defecation hole.
[0038]
[15] The absorbent article of
[14] , wherein the pair of slits include portions that are inclined or curved with respect to the first direction so that the slits move farther away from each other in the second direction as they move outward in the first direction.
[0039] In the above configuration, the width of the tip of the first part is increased, so that when the first part is folded back, the area covering the non-skin-facing side of the garment can be increased, thereby further preventing feces from adhering to the non-skin-facing side of the garment.
[0040]
[16] The absorbent article of
[14] , wherein the pair of slits includes portions that are inclined or curved with respect to the first direction so that the slits approach each other in the second direction as they move outward in the first direction.
[0041] In the above configuration, the width of the tip of the first part is narrowed, so that in the attached state, the parts adjacent to both sides of the first part are more likely to protrude inward of the defecation hole so as to cover part of the opening edge of the defecation hole of the wearing body. This makes it easier to cover part of the opening edge of the defecation hole of the wearing body, more effectively preventing feces from adhering to the wearing body.
[0042] [Embodiment] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate explanations will be omitted. The drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional ratios are not limited to those shown in the drawings.
[0043] FIG. 1 is a perspective view showing a diaper unit 1 including an absorbent article 20 according to one embodiment worn on a pet P. FIG. 2 is a plan view of the diaper unit 1 of FIG. 1, viewed from the skin-facing side. FIG. 3 is a plan view of the diaper unit 1 of FIG. 1, viewed from the non-skin-facing side. FIGS. 2 and 3 show the diaper unit 1 in a stretched state, stretched to a state where no wrinkles are formed. FIGS. 4 and 5, as well as FIGS. 8 to 18, similarly show diaper units or absorbent articles in a stretched state. The diaper unit 1 is a diaper to be worn on a pet P. In this specification, the term "pet" broadly includes vertebrates and invertebrates, and typically includes pet animals such as dogs, cats, rabbits, and hamsters. As an example, the diaper unit 1 is a diaper for a dog.
[0044] As shown in Figs. 1 to 3, the diaper unit 1 is composed of a reusable garment 10 (outer) and a disposable absorbent article 20 (inner) that is removably attached to the skin-facing side of the garment 10. Figs. 2 and 3 show the diaper unit 1 in an attached state in which the absorbent article 20 is attached to the skin-facing side of the garment 10. A detailed description of the "attached state" will be given later. The state in which the diaper unit 1 in the attached state is worn on a pet P is referred to as the "worn state" (see Fig. 1). In this embodiment, the diaper unit 1 will be described in the attached state unless otherwise specified.
[0045] In this embodiment, the "skin-facing side" refers to the side that faces the skin of the pet P when the diaper unit 1 is worn on the pet P. The "non-skin-facing side" refers to the side that faces away from the skin of the pet P when the diaper unit 1 is worn on the pet P. As shown in FIG. 2, the diaper unit 1 has a longitudinal direction Y (first direction) that connects the belly side to the back side of the pet P, a width direction X (second direction) that is perpendicular to the longitudinal direction Y and extends along the waist direction of the pet P, and a thickness direction Z that is perpendicular to the longitudinal direction Y and the width direction X. The thickness direction Z is the layering direction of the materials that make up the absorbent article 20 (such as the topsheet 23, backsheet 24, and absorber 30, which will be described later) (see FIG. 6).
[0046] In this embodiment, a straight line passing through the center of the wearing body 10 of the diaper unit 1 in the width direction X and parallel to the longitudinal direction Y is defined as a "center line CL1." In the attached state, the absorbent article 20 is attached to the wearing body 10 so that the center of the absorbent article 20 in the width direction X coincides with the center line CL1. Therefore, in this embodiment, unless otherwise specified, the center line CL1 is a center line common to the wearing body 10 and the absorbent article 20. In addition, a straight line passing through the center of the wearing body 10 of the diaper unit 1 in the longitudinal direction Y and parallel to the width direction X is defined as a "center line CL2."
[0047] (Wearing body configuration) 2, in the attached state, the garment 10 defines the outer shape of the diaper unit 1 when viewed in the thickness direction Z. As an example, the garment 10 is made of fabric formed by weaving or knitting yarn, and is configured to be reusable.
[0048] The garment 10 is divided into a ventral region 10a located on the ventral side of the pet P when worn, a dorsal region 10b located on the dorsal side of the pet P when worn, and a crotch region 10c located between the ventral region 10a and the dorsal region 10b. The ventral region 10a, the crotch region 10c, and the dorsal region 10b are aligned along the longitudinal direction Y from the ventral side (front) to the dorsal side (rear) of the pet P. As an example, if the garment 10 is divided into four equal parts in the longitudinal direction Y, the one region located on the most ventral side corresponds to the ventral region 10a, the one region located on the most dorsal side corresponds to the dorsal region 10b, and the two regions located between the ventral region 10a and the dorsal region 10b (i.e., the center of the garment 10 in the longitudinal direction Y) correspond to the crotch region 10c.
[0049] A pair of flap portions F1 protruding outward in the width direction X is formed on both sides of the ventral region 10a in the width direction X. Similarly, a pair of flap portions F2 protruding outward in the width direction X is formed on both sides of the dorsal region 10b in the width direction X. A pair of engagement portions 12 is provided on the pair of flap portions F1. A target portion 13 is provided in the region between the pair of flap portions F2 in the dorsal region 10b.
[0050] Each engaging portion 12 has a rectangular shape with its longitudinal direction aligned with the longitudinal direction Y, and is disposed on the skin-facing surface 10f of the garment 10 near the abdominal end 10d of the garment 10. The engaging portion 12 is, for example, a hook-and-loop fastener (for example, a plurality of hook-shaped members) configured to be engageable with the target portion 13.
[0051] The target portion 13 has a rectangular shape with the longitudinal direction being the width direction X, and is disposed on the non-skin-facing surface 10g of the garment 10 near the back end 10e of the garment 10. As shown in FIG. 1 , in the worn state, the pair of engagement portions 12 are engaged with the target portion 13.
[0052] As shown in Figs. 1 to 3, the garment 10 is formed with a defecation hole 14. The defecation hole 14 is configured to allow the feces of the pet P to pass through and also to allow the tail Pb of the pet P to pass through. That is, in this embodiment, the defecation hole 14 also functions as a tail insertion hole for passing the tail Pb of the pet P through. However, the defecation hole 14 and the tail insertion hole may be provided separately in the garment 10.
[0053] As an example, the defecation hole 14 is a substantially U-shaped opening that penetrates the garment in the thickness direction Z. The defecation hole 14 is formed in the crotch region 10c, and is formed between the center line CL2 in the longitudinal direction Y and the ventral end of the dorsal region 10b. The defecation hole 14 is located in the center of the garment 10 in the width direction X, and is formed symmetrically with respect to the center line CL1. The opening edge of the defecation hole 14 is composed of a ventral edge 14a, a pair of side edges 14b, and a dorsal edge 14c. The ventral edge 14a extends linearly along the width direction X. The pair of side edges 14b extend linearly from both ends of the ventral edge 14a in the width direction X toward the dorsal side. The dorsal edge 14c is connected to the dorsal ends of the pair of side edges 14b and is formed in a semicircular shape that convex toward the dorsal side.
[0054] (Configuration of absorbent article) Next, the configuration of the absorbent article 20 will be described with reference to Figs. 2 to 7. Fig. 4 is a plan view of the absorbent article 20 of Fig. 1 as seen from the skin-facing side. Fig. 5 is a plan view of the absorbent article 20 of Fig. 1 as seen from the non-skin-facing side. Fig. 6 is a cross-sectional view of the absorbent article 20 taken along line VI-VI in Fig. 4. Fig. 7 is a cross-sectional view of the diaper unit 1 taken along line VII-VII in Fig. 2.
[0055] 2, in the attached state, the absorbent article 20 is attached to the skin-facing side of the wearing body 10. The absorbent article 20 is a disposable absorbent article that absorbs, for example, urine excreted by a pet P. The absorbent article 20 is attached to the wearing body 10 by, for example, a second joining portion 62 described below.
[0056] 2 to 6, the absorbent article 20 has a main body portion 21 extending in the longitudinal direction Y and the width direction X. The main body portion 21 has a top sheet 23, a back sheet 24, a pair of side sheets 25, and an absorbent body 30.
[0057] The top sheet 23 is a liquid-permeable sheet that is placed in a position facing the skin of the pet P when the pad is worn, and faces the skin of the pet P. The top sheet 23 can be formed, for example, from a liquid-permeable nonwoven or woven fabric, a synthetic resin film having liquid-permeable holes, or a composite sheet of these.
[0058] The back sheet 24 is a liquid-impermeable sheet that is placed on the side opposite the skin-facing side of the pet P when the device is worn. The back sheet 24 can be formed, for example, from a liquid-impermeable nonwoven fabric, a synthetic resin film, or a composite sheet of these. In this embodiment, the back sheet 24 is a leak-proof sheet formed, for example, from a liquid-impermeable synthetic resin film. However, the back sheet 24 is not limited to a leak-proof sheet. The back sheet 24 may also be formed from a sheet in which a nonwoven fabric is bonded to a leak-proof sheet.
[0059] As shown in FIGS. 4 and 6 , the pair of side sheets 25 are sheets for forming leg side gathers LSG (leak-preventing gathers), which are upright leak-preventing gathers. The side sheets 25 may be formed, for example, from a water-repellent or hydrophobic nonwoven fabric. As shown in FIG. 4 , each side sheet 25 is disposed on both sides of the main body portion 21 in the width direction X so as to expose the central portion of the topsheet 23 in the width direction X. Each side sheet 25 extends along the longitudinal direction Y from the ventral end 21d of the main body portion 21 to the dorsal end 21e of the main body portion 21. As shown in FIG. 6 , the outer end of each side sheet 25 in the width direction X coincides with the outer end of the backsheet 24, forming the outer end 21s of the main body portion 21. The inner portion of each side sheet 25 in the width direction X is folded back toward the non-skin-facing side. An elastic member 27 stretched in the longitudinal direction Y is disposed between the folded side sheets 25. The elastic member 27 is, for example, rubber thread.
[0060] As shown in Fig. 4, each side sheet 25 is joined (fixed) to the top sheet 23 at fixing portions R surrounded by dashed lines and hatched with diagonal lines. Each fixing portion R is disposed over the entire area in the longitudinal direction Y of the main body portion 21. Each fixing portion R has a fixing portion R1 extending in the longitudinal direction Y along the outer end of the fixing portion R in the width direction X, a rectangular fixing portion R2 formed at the ventral end of the fixing portion R in the longitudinal direction Y, and a rectangular fixing portion R3 formed at the dorsal end of the fixing portion R in the longitudinal direction Y.
[0061] The upright portions 25a are formed by the portions of the side sheets 25 between the inner end R2a of the fixed portion R2 in the longitudinal direction Y and the inner end R3a of the fixed portion R3 in the longitudinal direction Y (i.e., the portions of the side sheets 25 where the elastic members 27 are disposed and which are not joined to the topsheet 23). The upright portions 25a function as leg side gathers LSG by standing up due to contraction of the elastic members 27. More specifically, the upright portions 25a are configured such that, by having both ends in the longitudinal direction Y fixed by the fixed portions R2 and R3 and contracting in the longitudinal direction Y, they stand up with the inner end R1a of the fixed portion R1 in the width direction X as a fulcrum. In other words, the end R1a of the fixed portion R1 functions as a fulcrum for the leg side gathers LSG to stand up.
[0062] The absorbent body 30 is disposed between the top sheet 23 and the back sheet 24. As shown in FIG. 6, the absorbent body 30 is composed of an absorbent core 31 and a pair of core wraps 32 covering the upper and lower surfaces of the absorbent core 31. The absorbent core 31 is a member that absorbs urine from the pet P and has liquid absorption and liquid retention properties. The absorbent core 31 is a laminate of absorbent materials including, for example, pulp or superabsorbent polymer (SAP), or a mixture thereof. The pair of core wraps 32 are, for example, tissue or nonwoven fabric sheets. As an example, the absorbent core 31 is formed in a rectangular shape with the longitudinal direction Y as the longitudinal direction when viewed from the thickness direction Z.
[0063] The main body portion 21 has a pair of elastic members 28 that are arranged to extend in the longitudinal direction Y along the outer end portion 21s of the main body portion 21 in the width direction X and that contract in the longitudinal direction Y. Each elastic member 28 is arranged, for example, between the outer end portion 31s of the absorbent core 31 and the outer end portion 21s of the main body portion 21 in the width direction X. Each elastic member 28 is, for example, rubber thread, similar to the elastic member 27. In this embodiment, as shown in FIG. 6 , each elastic member 28 is arranged between the top sheet 23 and the back sheet 24. The pair of elastic members 28 contract in the longitudinal direction Y when worn, causing the outer end portion 21s of the main body portion 21 to function as leg side gathers that fit around the legs of the pet P.
[0064] (Outline of the protrusion) As shown in FIGS. 4 and 5 , the main body portion 21 has a ventral protruding portion 40 and a dorsal protruding portion 50 (protruding portion). The ventral protruding portion 40 protrudes outward along the longitudinal direction Y from the ventral end portion 31a of the absorbent core 31 in the longitudinal direction Y. The ventral protruding portion 40 has a protruding main body portion 41 formed in a rectangular shape with the width direction X as its longitudinal direction. In this embodiment, the width of the protruding main body portion 41 in the width direction X is equal to the width of the main body portion 21 in the width direction X. The width of the protruding main body portion 41 in the width direction X is greater than the width of the absorbent core 31 in the width direction X. As an example, the protruding main body portion 41 is configured to include a topsheet 23, a backsheet 24, and a pair of core wraps 32. A U-shaped recess 41a is formed in the ventral end portion of the protruding main body portion 41.
[0065] The back-side protrusion 50 protrudes outward along the longitudinal direction Y from the back-side end 31b of the absorbent core 31 in the longitudinal direction Y. The back-side protrusion 50 has a protrusion main body 51 formed in a rectangular shape with the width direction X as its longitudinal direction, and a convex portion 52 (first portion) protruding outward in the longitudinal direction Y from the protrusion main body 51. In this embodiment, the width of the protrusion main body 51 in the width direction X is equal to the width of the main body 21 in the width direction X. The width of the protrusion main body 51 in the width direction X is greater than the width of the absorbent core 31 in the width direction X. As an example, the protrusion main body 51 is configured to include a topsheet 23, a backsheet 24, and a pair of core wraps 32.
[0066] The protrusion 52 protrudes toward the back side (outside) in the longitudinal direction Y from the central portion of the protruding main body portion 51 in the width direction X. The protrusion 52 is formed at a position including the center line CL1 of the main body portion 21 in the width direction X. The protrusion 52 is located more inward than the outer end portions 21s on both sides of the main body portion 21 in the width direction X. In other words, the width W1 of the base end portion 52a of the protrusion 52 in the width direction X is smaller than the width W2 of the back end portion 21e of the main body portion 21 in the width direction X. The protrusion 52 protrudes more outward in the longitudinal direction Y than both side portions 54 adjacent to both sides of the protrusion 52 in the width direction X.
[0067] As an example, the protrusion 52 is configured to include a top sheet 23 and a back sheet 24 . The protrusions 52 are configured to be independently foldable. Specifically, the protrusions 52 are folded back portions that can be folded back toward the non-skin-facing side, independently of the protruding main body portions 51, with the base ends 52a of the protrusions 52 as the folding starting point. As an example, the total basis weight of the protrusions 52 is set to be smaller than the total basis weight of the absorbent core 31. This makes the rigidity of the protrusions 52 lower than the rigidity of the absorbent core 31, making the protrusions 52 easier to bend than the absorbent core 31.
[0068] Figure 7 is a cross-sectional view of the absorbent article 20 taken along line VII-VII in Figure 2. As shown in Figures 2, 3, and 7, in the attached state, the convex portions 52 are folded back to the non-skin-facing side through the defecation opening 14 of the garment 10. In this example, a portion including the tip portions 52b of the convex portions 52 is joined to the non-skin-facing surface 10g of the garment 10 by first joining portions 61, which will be described later.
[0069] Here, in this embodiment, the "attached state" refers to a state in which the absorbent article 20 is attached to the skin-facing side of the wearing body 10, and at least a portion of the convex portions 52 of the absorbent article 20 overlaps the defecation hole 14 of the wearing body 10 when viewed from the thickness direction Z. In this example, the main body 21 of the absorbent article 20 is joined to the skin-facing surface 10f of the wearing body 10 by a second joining portion 62 described below. Furthermore, when viewed from the thickness direction Z, a portion including the base end portion 52a of the convex portions 52 overlaps the defecation hole 14. The convex portions 52 are joined to the non-skin-facing surface 10g of the wearing body 10 by a first joining portion 61.
[0070] Next, the procedure for attaching the absorbent article 20 will be described. As shown in FIGS. 2 and 3, first, the main body portion 21 is attached to the skin-facing side of the garment 10 via the second joining portion 62. The main body portion 21 is attached to the garment 10 so that the absorbent core 31 is positioned ventral to the defecation hole 14 in the longitudinal direction Y and the protruding portion 52 overlaps the defecation hole 14 when viewed from the thickness direction Z. As an example, the main body portion 21 is attached to a position in the longitudinal direction Y where the base end 52a of the protruding portion 52 overlaps the ventral edge 14a of the defecation hole 14. Next, as shown in FIG. 7, the tip end 52b of the protruding portion 52 is passed through the defecation hole 14 and folded back to the non-skin-facing side, and the protruding portion 52 is joined to the non-skin-facing surface 10g of the garment 10 via the first joining portion 61. The absorbent article 20 is attached to the garment 10 via this procedure.
[0071] Here, the absorbent article 20 satisfies the following requirement A in at least one of the ventral-side protruding portion 40 and the dorsal-side protruding portion 50.
[0072] Requirement A: "The main body portion has at least one protruding portion that protrudes outward along the first direction from at least one end of the absorbent core in the first direction, and the at least one protruding portion is located inward from both end portions of the main body portion in a second direction perpendicular to the first direction, includes a center line of the main body portion along the first direction, and has a first portion that can be bent independently."
[0073] In this embodiment, requirement A is satisfied at least in the dorsal protrusion 50. That is, the dorsal protrusion 50 has independently foldable convex portions 52 formed inward of the outer ends 21s on both sides of the main body 21 in the width direction X, including a center line CL1 along the longitudinal direction Y of the main body 21. This allows the convex portions 52 to be folded back toward the non-skin-facing side through the defecation hole 14 of the wearing body in the attached state. As a result, at least a part of the opening edge of the defecation hole 14 (for example, the ventral edge 14a) can be covered. This makes it possible to prevent feces from adhering to the wearing body 10 (for example, the opening edge of the defecation hole 14) during defecation.
[0074] (Configuration of joint) As shown in FIGS. 5 and 7 , first bonding portions 61 (first bonding portions) for attaching the protrusions 52 to the non-skin-facing surface 10g of the wearing body 10 are formed on the non-skin-facing surface 52g of the protrusions 52 (in this example, the non-skin-facing surface of the backsheet 24). As an example, the first bonding portions 61 are formed of a hot melt adhesive. The first bonding portions 61 are configured to be able to follow the movement of the wearing body 10 when worn, and are configured to be easily detachable from the wearing body 10 after use of the absorbent article 20. However, the first bonding portions 61 are not limited to hot melt adhesive. For example, the first bonding portions 61 may be a hook-and-loop fastener (e.g., a plurality of hook-shaped members) configured to be able to engage with the non-skin-facing surface 10g of the wearing body 10. Alternatively, the first bonding portions 61 may be adhesive tape.
[0075] In the above configuration, for example, the convex portion 52 that passes through the defecation hole 14 of the wearing body 10 and is folded back to the non-skin facing side in the attached state can be attached to the non-skin facing surface 10g of the wearing body 10 by the first joining portion 61. This makes it possible to prevent the convex portion 52 from shifting relative to the wearing body 10. In addition, in this case, since a portion of the non-skin facing surface 10g of the wearing body 10 is reliably covered by the convex portion 52, it is possible to more effectively prevent feces from adhering to the wearing body 10 when the pet P defecates while the wearing body 10 is being worn.
[0076] As shown in Fig. 5, of the three regions that divide the main body portion 21 into thirds in the longitudinal direction Y, the region located most ventrally is defined as the ventral region 21a, the region located most dorsally is defined as the dorsal region 21b, and the region located between the ventral region 21a and the dorsal region 21b is defined as the central region 21c. Here, the "three regions that divide the main body portion 21 into thirds in the longitudinal direction Y" are defined, for example, based on the length in the longitudinal direction Y of the outer end portion 21s of the main body portion 21. The ventral region 21a and the dorsal region 21b constitute outer regions that are located outside the central region 21c in the longitudinal direction Y.
[0077] As shown in FIGS. 5 and 7 , a pair of second joining portions 62 for attaching the main body portion 21 to the skin-facing surface 10f of the wearing body 10 is formed on each of the non-skin-facing surfaces 21g of the ventral region 21a and the dorsal region 21b (in this example, the non-skin-facing surface of the backsheet 24). That is, the second joining portions 62 are formed intermittently in the ventral region 21a and the dorsal region 21b, and no joining portion for attaching the main body portion 21 to the wearing body 10 is formed in the central region 21c. As an example, the second joining portions 62 are formed using a hot melt adhesive. The second joining portions 62 are configured to be able to follow the movement of the wearing body 10 when worn and to be easily detachable from the wearing body 10 after use of the absorbent article 20. However, the second joining portions 62 are not limited to a hot melt adhesive. For example, the second joining portions 62 may be a hook-and-loop fastener (e.g., a plurality of hook-shaped members) configured to be able to engage with the skin-facing surface 10f of the wearing body 10. The second bonding portion 62 may also be an adhesive tape.
[0078] The pair of second joints 62 is composed of a ventral joint 63 and a dorsal joint 64. The ventral joint 63 is formed in a rectangular shape with the width direction X as its longitudinal direction. The ventral joint 63 is formed in a region of the ventral region 21a that includes a part of the protruding main body portion 41 and the ventral end 31a of the absorbent core 31. The outer end 63a of the ventral joint 63 in the longitudinal direction Y coincides with the ventral end 21d of the main body portion 21. The inner end 63b of the ventral joint 63 is located more inward than the ventral end 31a of the absorbent core 31 in the longitudinal direction Y. The width of the ventral joint 63 in the width direction X is greater than the width of the absorbent core 31 in the width direction X and smaller than the width of the main body portion 21 in the width direction X. The ventral joint 63 includes a portion that overlaps with the center line CL1 of the main body portion 21 along the longitudinal direction Y.
[0079] The back-side joining portion 64 is formed in a rectangular shape with the width direction X as its longitudinal direction. The back-side joining portion 64 is formed in a region of the back region 21b that includes a part of the protruding main body portion 51 and the back-side end portion 31b of the absorbent core 31. In this example, the back-side joining portion 64 is integrally continuous with the first joining portion 61 formed on the convex portion 52 and across the base end portion 52a of the convex portion 52. The outer end portion 64a of the back-side joining portion 64 in the longitudinal direction Y coincides with the back-side end portion 21e of the main body portion 21. The inner end portion 64b of the back-side joining portion 64 is located more inward than the back-side end portion 31b of the absorbent core 31 in the longitudinal direction Y. The width of the back-side joining portion 64 in the width direction X is greater than the width of the absorbent core 31 in the width direction X and smaller than the width of the main body portion 21 in the width direction X. The back-side joining portion 64 includes a portion that overlaps with the center line CL1 of the main body portion 21 along the longitudinal direction Y.
[0080] In the above configuration, the main body portion 21 can be attached to the garment 10 by the second joining portion 62. This prevents the main body portion 21 from shifting relative to the garment 10. Furthermore, no joining portion for attaching the main body portion 21 to the garment 10 is formed in the central region 21c of the main body portion 21. In this configuration, the central region 21c of the main body portion 21 is not joined to the garment 10 in the attached state. This prevents the main body portion 21 from losing its shape in response to the movement of the garment 10 in the worn state, thereby preventing urine leakage from the main body portion 21. This also prevents a gap from being formed between the main body portion 21 and the garment 10 in the region near the protruding portion 52 of the main body portion 21 due to the deformation of the main body portion 21. As a result, it is possible to prevent the protruding portion 52 from getting into the gap and feces from getting between the main body portion 21 and the garment 10.
[0081] 5, the back-side joints 64 are formed at least in both side portions 54 of the back-side protruding portion 50 that are adjacent to both sides of the convex portion 52 in the width direction X. With the above configuration, it is possible to prevent the position of the convex portion 52 from shifting relative to the garment 10 when the garment is worn.
[0082] As shown in FIGS. 4 to 6 , the main body portion 21 has a pair of side sheets 25 for forming leg side gathers LSG that are configured to stand up due to elastic members 27 that contract in the longitudinal direction Y. The elastic members 27 are fixed to the side sheets 25 by fixed ends 27a, 27b formed at both ends in the longitudinal direction Y. As shown in FIG. 4 , the fixed ends 27a, 27b of the elastic members 27 overlap the absorbent core 31 in the longitudinal direction Y. Here, in this embodiment, the "fixed end of the elastic member" is defined as "the end in the first direction within the range where a contractile force is generated in the stretched state." Therefore, the fixed ends 27a, 27b are not necessarily limited to the physical ends of the elastic members 27. For example, the fixed ends 27a, 27b may be formed more inward in the longitudinal direction Y than the physical ends of the elastic members 27.
[0083] In this example, the fixed end 27a is a portion including the ventral end of the elastic member 27 in the longitudinal direction Y. The fixed end 27a is located more inward than the inner end 63b of the ventral joint 63 in the longitudinal direction Y. The fixed end 27b is a portion including the dorsal end of the elastic member 27 in the longitudinal direction Y. The fixed end 27b is located more inward than the inner end 64b of the dorsal joint 64 in the longitudinal direction Y. In the above configuration, the fixed ends 27a and 27b are located more inward than the ventral joint 63 and the dorsal joint 64 in the longitudinal direction Y, respectively. This prevents the contractile force of the elastic member 27 from being generated in the regions where the ventral joint 63 and the dorsal joint 64 are formed. This prevents the shape of the ventral joint 63 and the dorsal joint 64 from being distorted due to the contractile force of the elastic member 27. As a result, the fit between the main body 21 and the wearing body 10 can be improved.
[0084] As shown in FIGS. 4 and 5, the distance D1 in the longitudinal direction Y between the back end 31b of the absorbent core 31 and the base end 52a, which is the starting point of the fold of the convex portion 52, is 25 mm or less. In the above configuration, by setting the distance D1 to 25 mm or less, the absorbent core 31 extends to the vicinity of the defecation hole 14 when worn. As a result, even in a pet P (e.g., a female dog) whose urethral opening (not shown) is close to the anus Pa and whose urethral opening is likely to be close to the defecation hole 14 when worn, the absorbent core 31 easily covers the urethral opening, thereby preventing urine from leaking from the defecation hole 14 during urination (see FIG. 1). Furthermore, even if loose stool gets into the skin-facing side of the main body portion 21, the loose stool can be prevented from spreading between the pet P and the main body portion 21. Furthermore, even if the absorbent core 31 absorbs urine and becomes heavy when worn, causing the main body 21 to sag, the absorbent core 31 extends close to the defecation hole 14, thereby effectively preventing urine leakage caused by misalignment of the urethral opening.
[0085] To further enhance the above-mentioned effect, the distance D1 is preferably 15 mm or less, and more preferably 10 mm or less. Alternatively, the distance D1 is preferably 1 / 15 or less, and more preferably 1 / 25 or less, of the length of the absorbent core 31 in the longitudinal direction Y. As an example, when the length of the absorbent core 31 in the longitudinal direction Y is 170 to 240 mm, the distance D1 can be set to about 10 mm.
[0086] The protrusions 52 are provided only on the back end 21e of the main body 21 in the longitudinal direction Y. With the above configuration, when the user attaches the main body 21 to the garment 10, the user can easily confirm that the side on which the protrusions 52 are provided is the back side.
[0087] The protrusions 52 protrude outward in the longitudinal direction Y further than the side portions 54 adjacent to both sides of the protrusions 52 in the width direction X. In the above configuration, the protrusions 52 protrude outward at the ends of the main body 21, allowing the user to easily recognize the position of the protrusions 52.
[0088] FIG. 8 is a plan view showing a manufacturing method of the absorbent article 20 of FIG. 1. A continuous laminate 70 is prepared, including a topsheet 23, a backsheet 24, and sidesheets 25 that are continuous in the longitudinal direction Y. A plurality of absorbers 30 are arranged at predetermined intervals in the longitudinal direction Y between the topsheet 23 and the backsheet 24. Next, this continuous laminate 70 is cut along the width direction X to separate it into a plurality of main body portions 21. At this time, as shown in FIG. 8, a curved portion L1a of a cutting line L1 that forms a convex portion 52 at the back-side end 21e of one main body portion 21 in the longitudinal direction Y simultaneously forms a concave portion 41a having a shape corresponding to the convex portion 52 at the ventral end 21d of another main body portion 21 adjacent in the longitudinal direction Y. The concave portion 41a has a shape that can fit into the convex portion 52, for example.
[0089] As shown in FIG. 4 , a recess 41a having a shape corresponding to the protrusion 52 is formed in the ventral end 21d of the main body portion 21 in the longitudinal direction Y. In the above configuration, for example, when manufacturing a plurality of main body portions 21 from a continuous laminate 70, the cutting line L1 for forming the protrusion 52 of one main body portion 21 can be used to simultaneously form the recess 41a of another adjacent main body portion 21. As a result, waste material generated by forming the protrusion 52 can be reduced, and manufacturing costs can be reduced. Furthermore, by providing the recess 41a, the rigidity of the main body portion 21 in the width direction X can be reduced. This makes the main body portion 21 more easily deformable in the width direction X, and therefore more easily conforms to the legs of the pet P, for example, between the pet P's legs. As a result, the discomfort felt by the pet P when wearing the product can be reduced.
[0090] As shown in FIG. 4, the distance D2 in the longitudinal direction Y between the ventral end 31a of the absorbent core 31 and the ventral end 21d of the main body portion 21 (i.e., the length in the longitudinal direction Y of the protruding main body portion 41) is, for example, 20 mm or less. With the above configuration, it is possible to prevent the absorbent core 31 from moving out of position with the urethral opening (urination position) of the pet P when the absorbent core 31 is worn. As a result, it is possible to effectively prevent urine leakage. The distance D2 may be 8 to 1 / 13 of the length in the longitudinal direction Y of the absorbent core 31. As an example, when the length of the absorbent core 31 in the longitudinal direction Y is 170 to 240 mm, the distance D2 may be set to about 20 mm.
[0091] [Variations] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments. The materials and shapes of each component are not limited to those described above, and various materials and shapes can be used. Furthermore, some components of the absorbent article 20 described above may be modified to other configurations or omitted. The configurations of the above-described embodiments and the first to fifth modified examples described below may be combined in any manner.
[0092] The configuration of an absorbent article 20A according to a first modified example will be described with reference to Figs. 9 to 13. Fig. 9 is a plan view of a diaper unit 1A including an absorbent article 20A according to a first modified example, viewed from the skin-facing side. Fig. 10 is a plan view of the absorbent article 20A of Fig. 9, viewed from the non-skin-facing side. Fig. 11 is a plan view of the absorbent article 20A of Fig. 9, viewed from the skin-facing side. Fig. 12 is a plan view of the absorbent article 20A of Fig. 9, viewed from the non-skin-facing side. Fig. 13 is a plan view showing a method for manufacturing the absorbent article 20A of Fig. 9.
[0093] As shown in Figures 9 to 12, the absorbent article 20A according to the first modified example differs from the absorbent article 20 according to the embodiment mainly in that the back-side protruding portion 50 has a tongue portion 56 (first portion) formed by a pair of slits 55 instead of the convex portion 52. Furthermore, in the absorbent article 20A, the ventral-side protruding portion 40 does not have a recess 41a formed therein, but has a tongue portion 46 formed by a pair of slits 45. The slit 45 and the tongue portion 46 have the same configuration as the slit 55 and the tongue portion 56, respectively, and therefore, the following description will mainly focus on the back-side slit 55 and the tongue portion 56, and will omit descriptions of the ventral-side slit 45 and the tongue portion 46 as appropriate.
[0094] 11, the pair of slits 55 extend linearly inward from the outer end 51b of the protruding main body portion 51 in the longitudinal direction Y, and are aligned in the width direction X across the center line CL1. As an example, the pair of slits 55 extend from the outer end 51b of the protruding main body portion 51 to the back end 30b of the absorbent body 30. Each slit 55 penetrates the topsheet 23 and the backsheet 24 that constitute the main body portion 21A in the thickness direction Z.
[0095] The tongue portion 56 is a portion formed between the pair of slits 55. The tongue portion 56 can be bent independently of the two side portions 54 in the width direction X, for example. In this example, the base end 56a, which is the starting point for folding back the tongue portion 56, overlaps with the back end 30b of the absorbent body 30 in the longitudinal direction Y. The distance D1 in the longitudinal direction Y between the base end 56a of the tongue portion 56 and the back end 31b of the absorbent core 31 is 25 mm or less. In this example, the distance D1 is, for example, approximately 10 to 15 mm. As shown in FIG. 9, in the attached state, the base end 56a of the tongue portion 56 overlaps with the ventral edge 14a in the longitudinal direction Y.
[0096] An example of a manufacturing method for an absorbent article 20A according to the first modified example will be described. As shown in Fig. 13, in this manufacturing method, similar to the manufacturing method for the absorbent article 20 according to the embodiment, first, a continuous laminate 70 that is continuous in the longitudinal direction Y is prepared. Next, a pair of slits S for forming a pair of slits 45, 55 is made in this continuous laminate 70 at positions that will become ends of the main body portion 21A in the longitudinal direction Y. As an example, the pair of slits S are made on both sides of the cutting line L2 in the longitudinal direction Y. Finally, the continuous laminate 70 is cut along the linear cutting line L2 along the width direction X to separate it into a plurality of main body portions 21A.
[0097] In the absorbent article 20A according to the first modification, at least the back-side protruding portion 50 satisfies the above-mentioned requirement A, as in the above-mentioned embodiment. That is, the back-side protruding portion 50 is formed with an independently foldable tongue portion 56 that is located inward of the outer end portions 21s on both sides of the main body portion 21A in the width direction X, includes a center line CL1 along the longitudinal direction Y of the main body portion 21A, and is capable of being folded. This achieves the same effects as the above-mentioned embodiment. Furthermore, in the above-mentioned configuration, for example, when manufacturing a plurality of main body portions 21A from the continuous laminate 70, the tongue portion 56 can be formed by a relatively simple process of forming a pair of slits in the back-side protruding portion 50. This reduces the effort required to form the tongue portion 56 compared to, for example, forming a tongue portion 56 with a complex shape. 9, the absorbent article 20A may be configured such that, in the attached state, the side portions 54 adjacent to both sides of the tongue portion 56 (specifically, the inner ends 54a of the side portions 54 in the width direction X) protrude inward from the defecation hole 14 so as to cover part of the opening edge of the defecation hole 14 of the wearing body 10 (in this example, the side edges 14b). This makes it possible to effectively prevent feces from adhering to the wearing body 10, even if, for example, the anus Pa of the pet P is misaligned with respect to the defecation hole 14.
[0098] In the absorbent article 20A according to the first modification, the ventral-side protruding portion 40 also satisfies requirement A in addition to the dorsal-side protruding portion 50. Specifically, the ventral-side protruding portion 40 has a tongue portion 46 (first portion) formed between a pair of slits 45 and capable of being bent independently. In the above configuration, the ventral-side protruding portion 40 and the dorsal-side protruding portion 50 are each provided with a tongue portion 46, 56. As a result, for example, when attaching the main body portion 21A to the garment 10, regardless of which end of the main body portion 21A is attached with the ventral side or the dorsal side, either the tongue portion 46, 56 can be passed through the defecation orifice 14 and folded back. This eliminates the need to check the attachment orientation of the main body portion 21A to the garment 10.
[0099] Fig. 14 is a plan view of an absorbent article 20B according to a second modified example, as viewed from the skin-facing side. Fig. 15 is a plan view showing a manufacturing method for the absorbent article 20B of Fig. 14. As shown in Fig. 14, the main body portion 21B of the second modified example differs from the absorbent article 20A according to the first modified example (see Fig. 11) in that a tongue portion 56 is formed only in the dorsal protruding portion 50, and no tongue portion 46 is formed in the ventral protruding portion 40. In the above configuration, the tongue portion 56 is provided only in the dorsal protruding portion 50. This allows the user to easily confirm, for example, that the side on which the tongue portion 56 is provided is the dorsal side when attaching the main body portion 21B to the garment 10.
[0100] 15, in the manufacturing method of the absorbent article 20B according to the second modification, before cutting and separating the continuous laminate 70 into a plurality of main body portions 21B, slits S are formed alternately (every other slit) at a plurality of cutting locations. By using this method, it is possible to form tongue portions 56 at only one end in the longitudinal direction Y of each separated main body portion 21B. This allows the main body portions 21B to be manufactured efficiently.
[0101] Fig. 16 is a plan view showing the back end portion of an absorbent article 20C according to a third modified example. As shown in Fig. 16, the absorbent article 20C (main body portion 21C) according to the third modified example differs from the absorbent article 20A according to the first modified example (see Fig. 11) in that the width in the width direction X of the tip end 56b of the tongue portion 56C is greater than the width in the width direction X of the base end 56a. The tongue portion 56C is formed in a shape in which the width in the width direction X increases as it moves outward in the longitudinal direction Y. From a different perspective, the tongue portion 56C is formed in a shape in which the width in the width direction X decreases as it moves inward in the longitudinal direction Y (an inward tapered shape).
[0102] In the absorbent article 20C, each of a pair of slits 55 includes a straight portion 55a and a curved portion 55b. The straight portion 55a extends linearly along the longitudinal direction Y at the inner end of the slit 55. The curved portion 55b extends from the outer end of the straight portion 55a toward the outside in the longitudinal direction Y. The curved portions 55b are curved so that they move away from each other in the width direction X as they extend outward in the longitudinal direction Y.
[0103] In the above configuration, the width of the tip end 56b of the tongue portion 56C is increased, so that when the tongue portion 56C is folded back, the area covering the non-skin-facing surface 10g of the garment 10 can be increased. This can further prevent feces from adhering to the non-skin-facing surface 10g of the garment 10. However, instead of the curved portions 55b, the slits 55 may include inclined portions that are inclined with respect to the longitudinal direction Y so that they move away from each other in the width direction X as they move outward in the longitudinal direction Y. Even in this case, the above-mentioned effect can be similarly obtained.
[0104] Fig. 17 is a plan view showing the back end portion of an absorbent article 20D according to a fourth modified example. As shown in Fig. 17, the absorbent article 20D (main body portion 21D) according to the fourth modified example differs from the absorbent article 20C according to the third modified example (see Fig. 16) in that the width in the width direction X of the tip end portion 56b of the tongue portion 56D is smaller than the width in the width direction X of the base end portion 56a. The tongue portion 56D is formed in a shape such that the width in the width direction X becomes narrower, for example, toward the outside in the longitudinal direction Y.
[0105] In the absorbent article 20D, each of the pair of slits 55 includes a curved portion 55c and a linear portion 55d. The curved portions 55c are curved at the inner end of the slit 55 so as to approach each other in the width direction X as they extend outward in the longitudinal direction Y. The linear portions 55d extend linearly from the outer end of the curved portions 55c toward the outside in the longitudinal direction Y.
[0106] In the above configuration, the width in the width direction X of the tip end 56b of the tongue portion 56D is narrowed, so that in the attached state, the side portions 54 adjacent to both sides of the tongue portion 56D are more likely to protrude toward the inside of the defecation hole 14. This makes it easier to cover part of the opening edge of the defecation hole 14 of the garment 10 (in this example, the side edges 14b), so that it is possible to more effectively prevent feces from adhering to the garment 10. However, instead of the curved portions 55c, the slits 55 may include inclined portions that are inclined with respect to the longitudinal direction Y so that they approach each other in the width direction X as they move outward in the longitudinal direction Y. Even in this case, the above-mentioned effect can be similarly obtained.
[0107] Fig. 18 is a plan view of an absorbent article 20E according to a fifth modified example, as viewed from the skin-facing side. As shown in Fig. 18, the absorbent article 20E according to the fifth modified example differs from the absorbent article 20 according to the embodiment in that outer end portions 31s on both sides of the absorbent core 31 in the width direction X include curved portions 31k. The curved portions 31k are curved so as to approach each other as they move inward in the longitudinal direction Y. As an example, the absorbent core 31 is formed in an hourglass shape, and the curved portions 31k form a constricted shape at the center of the absorbent core 31 in the longitudinal direction Y.
[0108] With the above configuration, the fit of the main body portion 21E to the legs of the pet P can be improved when the absorbent core 31 is worn. This can prevent urine leakage from the main body portion 21E. In addition, when the absorbent core 31 is worn, it can prevent the pet P from feeling uncomfortable when wearing the absorbent core 31 due to the outer ends 31s on both sides of the absorbent core 31 touching the legs of the pet P.
[0109] Moreover, the curved portion 31k is formed at least in the central region 21c. With the above configuration, the curved portion 31k can be positioned appropriately with respect to the legs of the pet P when the device is worn. This effectively prevents urine leakage from the main body portion 21E and prevents the pet P from feeling uncomfortable when wearing the device.
[0110] In the above embodiment, the first bonding portion 61 is formed on the non-skin-facing surface 52g of the protrusion 52 (see FIG. 5 ). However, the first bonding portion 61 does not have to be formed on the protrusion 52. That is, the non-skin-facing surface 52g of the protrusion 52 does not have to have a bonding portion for attaching the protrusion 52 to the garment 10. In this case, since the protrusion 52 is not bonded to the garment 10 when worn, for example, even when the pet P sits on the floor, the skin-facing surface 52f of the protrusion 52 can be folded toward the inside of the defecation hole 14 so as to face the pet P's anus Pa (see FIG. 1 ). This prevents the feces-adhering surface of the protrusion 52 (surface 52f in this example) from facing the floor when the pet P sits on the floor. As a result, feces can be prevented from adhering to the floor.
[0111] In the above embodiment, the fixed ends 27a, 27b of the elastic member 27 overlap with the absorbent core 31 in the longitudinal direction Y (see FIG. 4), but the positions of the fixed ends 27a, 27b are not limited to the above. The fixed ends 27a, 27b may be located outside the absorbent core 31 in the longitudinal direction Y. In this case, the contractile force of the elastic member 27 is generated over the entire area overlapping with the absorbent core 31 in the longitudinal direction Y. As a result, the leg side gathers LSG are more likely to stand up, allowing the leg side gathers LSG to naturally conform to the body shape of the pet P. This improves the fit to the body of the pet P.
[0112] In the above embodiment, the protrusions 52 are formed by the top sheet 23 and the back sheet 24 (see FIG. 7 ), but the materials forming the protrusions 52 are not limited to those described above. The protrusions 52 may be formed by only one of the top sheet or the back sheet. The protrusions 52 may be formed by including the core wrap 32 in addition to the top sheet 23 and the back sheet 24. The protrusions 52 may be formed by a sheet material separate from the top sheet 23, the back sheet 24, and the core wrap 32.
[0113] In the above embodiment, an example was shown in which the back-side protrusion 50 was composed of the protrusion main body portion 51 and the convex portion 52 (see FIGS. 4 and 5), but the configuration of the back-side protrusion 50 is not limited to this. For example, the convex portion 52 may be configured to protrude directly from the back-side end portion 31b of the absorbent core 31 in the longitudinal direction Y without passing through the protrusion main body portion 51. In this case, the back-side protrusion 50 may be configured only by the convex portion 52. [Explanation of symbols]
