[0003] [Patent Document 1] JP 2020-182 A [Patent Document 2] JP 2013-31380 A Summary of the Invention [Problem to be solved by the invention]

[0004] The belly wrap type pet absorbent articles described in the above Patent Documents 1 and 2 are put on a pet by grasping both longitudinal ends with the hands, unfolding the article, and wrapping it around the pet's waist. Since both ends of the pet absorbent article are generally made of a thin and soft material, depending on the size of the absorbent article, it may be difficult for the user to keep the absorbent article in an unfolded state while grasping both ends with the hands, and the user may have difficulty putting the absorbent article on.

[0005] An object of the present disclosure is to provide an absorbent article for pets that can be easily attached to the pet's body. [Means for solving the problem]

[0006] In one embodiment, an absorbent article for pets is provided that is worn by wrapping it around the waist of a pet. The absorbent article for pets is provided with a main body having a horizontally elongated shape having a longitudinal direction and a lateral direction, a top sheet arranged on the skin side, a back sheet arranged on the non-skin side, and an absorbent arranged between the top sheet and the back sheet, the main body having a first end arranged on one side in the longitudinal direction relative to the absorbent and a second end arranged on the other side in the longitudinal direction relative to the absorbent, an engagement member provided on the first end and engaging the first end and the second end, and a rigid sheet provided on at least one of the first end and the second end.

[0007] In the above-mentioned absorbent article for pets, a rigid sheet is provided on at least one of the first end and the second end. When wearing the absorbent article for pets, the user can easily spread out the absorbent article for pets by gripping this rigid sheet with their hands. In addition, by providing rigidity to at least one of the first end and the second end with the rigid sheet, deformation of the portion where the rigid sheet is provided (at least one of the first end and the second end) is suppressed when the absorbent article for pets is pulled in the longitudinal direction while gripping the first end and the second end with their hands, respectively. This makes it possible to easily maintain the absorbent article for pets in an unfolded state. Therefore, according to the above-mentioned aspect, the absorbent article for pets can be easily worn on the body of a pet.

[0008] In one embodiment, the main body has a first side edge disposed on one side in the longitudinal direction and a second side edge disposed on the other side in the longitudinal direction, the engaging member is disposed at a position spaced apart from the first side edge in the longitudinal direction, and the shortest distance from the first side edge or the second side edge to the rigid sheet may be shorter than the distance between the engaging member and the first side edge in the longitudinal direction. By disposing the engaging member at a position spaced apart from the first side edge in the longitudinal direction, the user can easily grasp the portion between the engaging member and the first side edge with his / her hand. Furthermore, by disposing the rigid sheet at a position relatively close to the first side edge or the second side edge, the user can easily grasp the rigid sheet with his / her hand when grasping the first end and the second end with his / her hand. Therefore, it is possible to more easily spread the absorbent article for pets, and as a result, it is possible to more easily wear the absorbent article for pets on the body of the pet.

[0009] In one aspect, the rigid sheet may be disposed at a position overlapping with a center line of the main body in the short side direction when viewed from the thickness direction of the main body. According to this aspect, since the rigid sheet is disposed at the central portion of the main body in the short side direction, it is easy for a user to grasp the rigid sheet with his / her hand.

[0010] In one embodiment, the width of the rigid sheet in the short direction may be half or more of the width of the absorbent body in the short direction. The relatively wide width of the rigid sheet further suppresses deformation of the portion where the rigid sheet is provided (at least one of the first end and the second end) when the absorbent article for pets is pulled in the longitudinal direction while the first end and the second end are grasped with the hands. This makes it easier to maintain the absorbent article for pets in an unfolded state.

[0011] In one aspect, the absorbent article further comprises a pair of leakproof sheets that can stand up relative to the top sheet along a pair of standing lines extending in the longitudinal direction at positions spaced apart from each other in the lateral direction, and the rigid sheet may extend in the lateral direction so as to partially overlap the pair of leakproof sheets when viewed in the thickness direction of the main body. By having the rigid sheet extend in the lateral direction so as to partially overlap the pair of leakproof sheets for blocking pet urine, it is possible to impart rigidity to the area between the pair of leakproof sheets of the main body. This suppresses deformation of that area, making it easier to maintain the pet absorbent article in an unfolded state.

[0012] In one embodiment, the rigid sheet may be disposed between the top sheet and the back sheet. According to this embodiment, the rigid sheet is less likely to peel off from the main body portion.

[0013] In one embodiment, the main body further includes one or more elastic members extending in the longitudinal direction and imparting elasticity to the main body, and the rigid sheet may be disposed at a position overlapping the one or more elastic members or the extension line of the one or more elastic members when viewed from the thickness direction of the main body. The multiple elastic members contract to follow changes in the posture and shape of the pet, thereby improving the fit of the absorbent article for pets. In addition, in the portion where the rigid sheet is provided (at least one of the first end and the second end), deformation due to contraction of the multiple elastic members (for example, turning up of the first end or the second end) is unlikely to occur. Therefore, even when multiple elastic members are provided, the absorbent article for pets can be easily maintained in an unfolded state.

[0014] In one embodiment, the main body further includes a pair of flap parts arranged on the outside of the absorbent body in the short-side direction, and a pair of outer elastic members provided on each of the pair of flap parts to give the pair of flap parts longitudinal stretchability, and the pair of flap parts may be warped toward the skin side on the outside of the rigid sheet in the short-side direction in a natural state due to the contraction force of the pair of outer elastic members. The pair of outer elastic members contract to follow changes in the posture and body shape of the pet, thereby improving the fit of the absorbent article for pets. In addition, since the pair of flap parts are warped toward the skin side on the outside of the rigid sheet in a natural state, the user can easily recognize the position of the rigid sheet. Therefore, the user can easily grasp the rigid sheet with his or her hands.

[0015] In one aspect, the ends of the pair of warped flaps may be located outboard of the inner edge of the rigid sheet in the longitudinal direction in a natural state. In this aspect, warping of the pair of flaps is relatively suppressed, so that the pet absorbent article can be prevented from being worn on the pet's body with the pair of flaps in a warped state.

[0016] In one embodiment, the absorbent article further includes a second rigid sheet different from the first rigid sheet, which is a rigid sheet. The first rigid sheet is provided at the first end, and the second rigid sheet is provided at the second end, and the length of the first rigid sheet in the longitudinal direction may be different from the length of the second rigid sheet in the longitudinal direction. According to this embodiment, when wearing the absorbent article for pets, the user can easily spread the absorbent article by grasping the first rigid sheet and the second rigid sheet with their hands. In addition, by providing rigidity to the first end and the second end with the first rigid sheet and the second rigid sheet, respectively, deformation of the first end and the second end is suppressed when the absorbent article for pets is pulled in the longitudinal direction while grasping the first end and the second end with their hands. Furthermore, since the length of the first rigid sheet is different from the length of the second rigid sheet, the user can easily recognize the orientation of the absorbent article for pets. Therefore, the absorbent article for pets can be more easily worn on the body of the pet.

[0017] In one embodiment, the bending rigidity of the rigid sheet may be greater than the bending rigidity of the top sheet. The relatively large bending rigidity of the rigid sheet further suppresses deformation of the portion where the rigid sheet is provided. Furthermore, the relatively small bending rigidity of the top sheet makes the portion of the top sheet where the rigid sheet is not provided more likely to deform in response to changes in the posture and shape of the pet. This allows the pet absorbent article to be more easily attached to the pet's body and improves the fit of the pet absorbent article.

[0018] In one embodiment, the color difference between the rigid sheet and the top sheet in the L*a*b color system may be 2 or more when viewed from the skin side. According to this embodiment, the rigid sheet can be easily recognized by the user. Therefore, the user can easily hold the rigid sheet with his / her hand.

[0019] In one embodiment, the rigid sheet may be disposed at a position overlapping the engaging member when viewed from the thickness direction of the main body. According to this embodiment, the engaging member is less likely to deform. Therefore, the engaging member can be easily engaged with the second end portion.

[0020] In one aspect, the rigid sheet may be disposed at a position not overlapping with the engaging member when viewed from the thickness direction of the main body portion. According to this aspect, the rigid sheet can be easily grasped with the hand without grasping the engaging member with the hand.

[0021] In one embodiment, the length of the rigid sheet in the longitudinal direction may be different from the length of the engagement member in the longitudinal direction. According to this embodiment, the rigid sheet and the engagement member can be distinguished from each other, so that the user can easily recognize the rigid sheet. Therefore, the user can easily grasp the rigid sheet with his / her hand.

[0022] In one embodiment, the tensile strength of the rigid sheet in the longitudinal direction may be greater than the tensile strength of the rigid sheet in the lateral direction. Since the tensile strength of the rigid sheet in the longitudinal direction is relatively large, deformation of the portion where the rigid sheet is provided (at least one of the first end and the second end) is more suppressed when the absorbent article for pets is pulled in the longitudinal direction while the first end and the second end are grasped with the hands. Therefore, the absorbent article for pets can be more easily maintained in the unfolded state.

[0023] In one embodiment, the backsheet comprises a liquid-impermeable back film, and the thickness of the rigid sheet may be greater than the thickness of the back film. The relatively large thickness of the rigid sheet allows the rigid sheet to be easily gripped by hand.

[0024] In one embodiment, the back sheet includes a liquid-impermeable back film, and the basis weight of the rigid sheet may be greater than the basis weight of the back film. The relatively large basis weight of the rigid sheet makes it easy to grip the rigid sheet with one's hand.

[0025] In one embodiment, the main body further includes one or more elastic members extending in the longitudinal direction and imparting elasticity to the main body, the top sheet includes a top nonwoven fabric, the back sheet includes a back nonwoven fabric, the rigid sheet is disposed at a position overlapping the one or more elastic members as viewed in the thickness direction of the main body, and at least one of the top nonwoven fabric and the back nonwoven fabric may include a folded portion folded at a position overlapping the rigid sheet in a natural state. According to this embodiment, when the rigid sheet is grasped by hand, the folded portion is caught by the hand, making it easy to grasp the rigid sheet by hand.

[0026] In one aspect, the main body includes at least one opening or at least one opening forming portion for forming at least one opening through which the pet's tail is not inserted and which improves the breathability of the internal space facing the top sheet when the pet absorbent article is worn on the pet, and the at least one opening or at least one opening forming portion may be arranged in a position aligned with the rigid sheet in the longitudinal direction as viewed from the thickness direction of the main body. According to this aspect, deformation of the opening or opening forming portion arranged in a position aligned with the rigid sheet in the longitudinal direction as viewed from the thickness direction of the main body is suppressed. For example, when the rigid sheet extends along the short side direction, the rigidity of the rigid sheet suppresses deformation or shrinkage of the main body in the short side direction. Therefore, it is possible to suppress the opening from being closed due to deformation or shrinkage of the main body in the short side direction, and it is possible to effectively improve the breathability of the pet absorbent article.

[0027] In one embodiment, the rigid sheet may be made of a nonwoven fabric. According to this embodiment, the rigid sheet can be easily formed.

[0028] In one aspect, the absorbent article further includes a second rigid sheet different from the first rigid sheet, which is a rigid sheet, and the main body has a first side edge arranged on one side in the longitudinal direction and a second side edge arranged on the other side in the longitudinal direction, the first rigid sheet may extend in the short direction along the first side edge, and the second rigid sheet may extend in the short direction along the second side edge. According to this aspect, when wearing the absorbent article for pets, the user can easily spread the absorbent article by gripping the first rigid sheet and the second rigid sheet with their hands. In addition, by providing rigidity to the first end and the second end with the first rigid sheet and the second rigid sheet, respectively, deformation of the first end and the second end is suppressed when the absorbent article for pets is pulled in the longitudinal direction while gripping the first end and the second end with their hands. Furthermore, in this aspect, the first rigid sheet and the second rigid sheet extend along the first side edge and the second side edge, respectively. This allows a user to easily grasp the first and second rigid sheets when grasping the first and second ends with their hands. According to this aspect, the pet absorbent article can be more easily worn on the pet's body. Effect of the Invention

[0029] According to various aspects of the present invention, the absorbent article for pets can be easily attached to the body of a pet. [Brief description of the drawings]

[0031] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. In the description of the drawings, the same elements are given the same reference numerals, and duplicated descriptions are 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.

[0032] Hereinafter, an absorbent article for pets according to an embodiment will be described. FIG. 1 is a perspective view that shows a schematic diagram of an absorbent article for pets 1 according to an embodiment. FIG. 2 is a plan view of the absorbent article for pets 1 as seen from the skin-facing side Z1. FIG. 3 is a plan view of the absorbent article for pets 1 shown in FIG. 2, with a pair of leak-proof gathers 40 omitted. FIG. 4 is a cross-sectional view of the absorbent article for pets 1 taken along line AA in FIG. 2. FIG. 5 is a cross-sectional view of the absorbent article for pets 1 taken along line BB in FIG. 2. The absorbent article for pets 1 shown in FIGS. 1 to 5 is a disposable diaper for pets that absorbs urine of pets. Note that FIG. 2 omits the illustration of a plurality of inner elastic members 61 and a plurality of outer elastic members 62, which will be described later.

[0033] FIG. 1 shows the absorbent article for pets 1 in a natural state. The natural state means a state in which no external force is applied to the absorbent article for pets 1. Meanwhile, FIGS. 2 to 5 show the absorbent article for pets 1 in an unfolded state. The unfolded state means a state in which the absorbent article for pets 1 is stretched to a state in which no wrinkles are formed. The skin-facing side Z1 is the side that faces the skin of the pet when the absorbent article for pets 1 is worn, and the non-skin-facing side Z2 is the side that faces the opposite side to the skin of the pet when the absorbent article for pets 1 is worn. In the following description, a person who puts the absorbent article for pets 1 on a pet is referred to as a "user". Typically, the user is the owner of the pet. In the following description, the positional relationship in the unfolded state will be described unless otherwise specified.

[0034] In this specification, pets broadly include vertebrates and invertebrates, and typically include pet animals such as dogs, cats, rabbits, and hamsters. The pet absorbent article 1 is particularly suitable for use with male pets whose urethral opening is located forward of the base of the hind legs. As shown in FIG. 2, the pet absorbent article 1 extends in a short side direction X aligned along the front-rear direction of the pet (direction connecting the head and the buttocks) and a long side direction Y aligned along the pet's waist direction. The short side direction X and the long side direction Y are perpendicular to each other. The thickness direction Z is perpendicular to the short side direction X and the long side direction Y, and includes a skin side Z1 facing the skin side of the pet when worn, and a non-skin side Z2 facing the opposite side to the skin side of the pet when worn. The pet absorbent article 1 is worn by wrapping it around the pet's waist.

[0035] The pet absorbent article 1 includes a main body 2. The main body 2 has a substantially rectangular (horizontally elongated) planar shape having a short side direction X and a long side direction Y. The main body 2 has a front edge 3 arranged on one end side in the short side direction X and a rear edge 4 arranged on the other end side in the short side direction X. When the pet absorbent article 1 is worn by a pet, the front edge 3 is arranged on the front leg side of the pet, and the rear edge 4 is arranged on the rear leg side of the pet. In the following description, the direction from the rear edge 4 to the front edge 3 may be referred to as the front side, and the direction from the front edge 3 to the rear edge 4 may be referred to as the rear side. The main body 2 also has a first side edge 5 arranged on one end side in the long side direction Y and a second side edge 6 arranged on the other end side in the long side direction Y.

[0036] The main body portion 2 includes a first end portion 7 disposed on one side in the longitudinal direction Y, a second end portion 8 disposed on the other side in the longitudinal direction Y, and a central portion 9 disposed between the first end portion 7 and the second end portion 8. In one embodiment, the first end portion 7 is a region located between an absorbent body 30 (described below) and a first side edge 5 in the longitudinal direction Y. The second end portion 8 is a region located between the absorbent body 30 and a second side edge 6 in the longitudinal direction Y.

[0037] The main body 2 includes a top sheet 10, a back sheet 20, and an absorbent 30. The top sheet 10 constitutes the surface of the main body 2 that is in contact with a pet, and is disposed on the skin-facing side Z1. The top sheet 10 has liquid permeability that allows, for example, pet urine to pass through to the absorbent 30 side. The top sheet 10 is located approximately at the center in the short direction X. The top sheet 10 is bonded to the back sheet 20 and the absorbent 30 with, for example, a hot melt adhesive. The top sheet 10 is composed of, for example, a nonwoven fabric (surface nonwoven fabric). Examples of the nonwoven fabric that constitutes the top sheet 10 include an air-through nonwoven fabric, a spunbond nonwoven fabric, and a point-bond nonwoven fabric.

[0038] The back sheet 20 constitutes the surface of the main body 2 that is located on the outside when worn, and is arranged on the non-skin-facing side Z2. The back sheet 20 includes a liquid-impermeable back film 21 and a back nonwoven fabric 22 arranged on the non-skin-facing side Z2 of the back film 21. The width of the back film 21 in the short direction X is narrower than the width of the back nonwoven fabric 22, and the back nonwoven fabric 22 extends beyond the back film 21 on both sides in the short direction X. The back film 21 may have substantially the same width as the back nonwoven fabric 22. The back nonwoven fabric 22 constitutes the outermost layer of the absorbent article 1 for pets. Examples of nonwoven fabrics that constitute the back nonwoven fabric 22 include air-through nonwoven fabrics, spunbond nonwoven fabrics, and point-bond nonwoven fabrics. The back film 21 is bonded to the back nonwoven fabric 22 and the absorbent body 30 with, for example, a hot melt adhesive. The back sheet 20 does not necessarily have to include both the back film 21 and the back nonwoven fabric 22, and may be composed of only one of the back film 21 and the back nonwoven fabric 22.

[0039] The absorbent 30 is disposed between the top sheet 10 and the back sheet 20. The absorbent 30 is located at the approximate center of the main body 2 and absorbs pet urine. The absorbent 30 has an approximately rectangular shape extending in the longitudinal direction Y. In one embodiment, the absorbent 30 includes an absorbent core containing pulp and a polymer absorbent (SAP) having water absorption properties, and a core wrap covering the surface of the absorbent core. For example, chemical pulp, cellulose fiber, rayon, acetate, or other cellulose fiber is used as the pulp of the absorbent core. For example, starch-based, acrylic acid-based, or amino acid-based particulate or fibrous polymer is used as the polymer absorbent. The absorbent 30 may be a SAP sheet that does not contain pulp and is mainly composed of SAP. The absorbent 30 shown in FIG. 4 is bonded to the top sheet 10 with a hot melt adhesive H1, and is bonded to the back sheet 20 (back film 21) with a hot melt adhesive H2.

[0040] 2, 4 and 5, the absorbent article for pet 1 further includes a pair of leakage prevention gathers 40. The pair of leakage prevention gathers 40 are provided on the topsheet 10 and are spaced apart from each other in the short direction X. The pair of leakage prevention gathers 40 are arranged so as to cover both side portions of the topsheet 10 in the short direction X from the skin-facing side Z1, and extend in the long direction Y over the entire length of the main body portion 2 in the long direction Y.

[0041] The pair of leakage preventing gathers 40 includes front leakage preventing gathers 41 provided along the front edge 3 and rear leakage preventing gathers 51 provided along the rear edge 4. In the embodiment shown in FIG. 4, the pair of leakage preventing gathers 40 are configured as individual members separated from other members, but the pair of leakage preventing gathers 40 may be formed by folding back the back surface nonwoven fabric 22 toward the top sheet 10 outside the main body portion 2 in the short direction X. In this case, a part of the back surface nonwoven fabric 22 folded back toward the top sheet 10 constitutes the pair of leakage preventing gathers 40, and the other part of the back surface nonwoven fabric 22 constitutes the back surface sheet 20 of the main body portion 2.

[0042] The front leakproof gathers 41 include a front leakproof sheet 42 and a front elastic member 43 arranged along the inner edge 42a of the front leakproof sheet 42 in the short direction X. The front leakproof sheet 42 is arranged on one side in the short direction X (the front edge 3 side). The rear leakproof gathers 51 include a rear leakproof sheet 52 and a rear elastic member 53 arranged along the inner edge 52a of the rear leakproof sheet 52 in the short direction X. The rear leakproof sheet 52 is arranged on the other side in the short direction X (the rear edge 4 side). Each of the front leakproof sheet 42 and the rear leakproof sheet 52 is made of a nonwoven fabric having water repellency or hydrophobicity. For example, the front leakproof sheet 42 and the rear leakproof sheet 52 are made of spunlace nonwoven fabric, spunbond nonwoven fabric, thermal bond nonwoven fabric, meltblown nonwoven fabric, SMS nonwoven fabric, needle punched nonwoven fabric, air-through nonwoven fabric, or the like.

[0043] 4, part of the inner portion of the front leakproof sheet 42 in the short direction X is folded back toward the non-skin facing side Z2, and a front elastic member 43 is disposed between the folded back front leakproof sheet 42. The front elastic member 43 is made of a stretchable material such as rubber or spandex that is contractible in the longitudinal direction Y. The front elastic member 43 is joined to the front leakproof sheet 42 with a hot melt adhesive in a state stretched in the longitudinal direction Y.

[0044] A part of the inner portion of the rear leakproof sheet 52 in the short direction X is folded back toward the non-skin facing side Z2, and a rear elastic member 53 is disposed between the folded back rear leakproof sheet 52. The rear elastic member 53 is made of a stretchable material such as rubber or spandex that is contractible in the longitudinal direction Y. The rear elastic member 53 is joined to the rear leakproof sheet 52 with a hot melt adhesive in a state stretched in the longitudinal direction Y.

[0045] As shown in Fig. 2, the front leakproof sheet 42 and the rear leakproof sheet 52 are partially joined to the top sheet 10 or the back sheet 20 on the outer side of the absorbent body 30. For ease of explanation, the areas of the front leakproof sheet 42 and the rear leakproof sheet 52 joined to the top sheet 10 are shown shaded in Fig. 2.

[0046] The front leakproof sheet 42 includes a horizontal fixing portion 44, a first vertical fixing portion 45, a second vertical fixing portion 46, and a front standing portion 47. The horizontal fixing portion 44, the first vertical fixing portion 45, and the second vertical fixing portion 46 are areas of the front leakproof sheet 42 that are joined to the top sheet 10. The front standing portion 47 is an area of ​​the front leakproof sheet 42 that is not joined to the top sheet 10.

[0047] The lateral fixing part 44 is disposed on one side in the short side direction X (the front end edge 3 side) of the absorbent body 30, and extends along the longitudinal direction Y. The lateral fixing part 44 is joined to the topsheet 10 with, for example, a hot melt adhesive H. Note that a part of the front leakproof sheet 42 disposed outside the lateral fixing part 44 in the short side direction X may also be fixed to the topsheet 10. A front standing line 44a is formed at the boundary between the lateral fixing part 44 and the front standing part 47, which serves as a standing fulcrum for the front standing part 47 in the short side direction X.

[0048] The front standing line 44a is disposed between the center line CL in the short-side direction X of the main body 2 and the front edge 3, and extends along the longitudinal direction Y. For example, the front standing line 44a is disposed between the front edge of the absorber 30 and the front edge 3. Note that the front standing line 44a may partially overlap the absorber 30 when viewed from the thickness direction Z.

[0049] The first vertical fixing part 45 and the second vertical fixing part 46 are arranged on the outer side of the absorbent body 30 in the longitudinal direction Y. The first vertical fixing part 45 is arranged on one side in the longitudinal direction Y (the first side edge 5 side) and is joined to the main body part 2 in a state where it is leaning inward in the short side direction X. The second vertical fixing part 46 is arranged on the other side in the longitudinal direction Y (the second side edge 6 side) and is joined to the main body part 2 in a state where it is leaning inward in the short side direction X. Each of the first vertical fixing part 45 and the second vertical fixing part 46 is joined to the topsheet 10 by, for example, a hot melt adhesive H.

[0050] The first vertical fixing portion 45 and the second vertical fixing portion 46 are spaced apart from each other on the inside in the short side direction X relative to the horizontal fixing portion 44. Each of the first vertical fixing portion 45 and the second vertical fixing portion 46 is a set of a plurality of fixing portions (four in the example of FIG. 2) arranged at intervals from each other in the short side direction X.

[0051] The front standing portion 47 is formed by a portion of the front leakproof sheet 42 between the first vertical fixing portion 45 and the second vertical fixing portion 46 (i.e., a portion of the front leakproof sheet 42 where the front elastic member 43 is disposed and which is not joined to the topsheet 10). The front standing portion 47 stands by expansion and contraction of the front elastic member 43. As an example, the front standing portion 47 is configured to stand against the topsheet 10 along the front standing line 44a by contracting the front elastic member 43 in the longitudinal direction Y with both ends in the longitudinal direction Y fixed by the first vertical fixing portion 45 and the second vertical fixing portion 46.

[0052] The rear leakproof sheet 52 includes a lateral fixing portion 54 and a rear standing portion 55. The lateral fixing portion 54 is an area of ​​the rear leakproof sheet 52 that is joined to the topsheet 10. The rear standing portion 55 is an area of ​​the rear leakproof sheet 52 that is not joined to the topsheet 10.

[0053] The lateral fixing part 54 is disposed on the other side in the short side direction X (the rear end edge 4 side) of the absorbent body 30, and extends along the longitudinal direction Y. The lateral fixing part 54 is joined to the topsheet 10, for example, with a hot melt adhesive H. Note that a part of the rear leakproof sheet 52 disposed outside the lateral fixing part 54 in the short side direction X may also be fixed to the topsheet 10. A rear standing line 54a is formed at the boundary between the lateral fixing part 54 and the rear standing part 55, which serves as a standing fulcrum for the rear standing part 55 in the short side direction X.

[0054] The rear standing line 54a is disposed between the center line CL in the short-side direction X of the main body 2 and the rear edge 4, and extends along the longitudinal direction Y. For example, the rear standing line 54a is disposed between the rear edge of the absorbent body 30 and the rear edge 4. Note that the rear standing line 54a may partially overlap the absorbent body 30 when viewed from the thickness direction Z.

[0055] The rear standing portion 55 is formed by a portion of the rear leakproof sheet 52 that is disposed inside the lateral fixing portion 54 in the short direction X (i.e., a portion of the rear leakproof sheet 52 on which the rear elastic member 53 is disposed and which is not joined to the topsheet 10). The rear standing portion 55 stands up due to expansion and contraction of the rear elastic member 53. As an example, the rear standing portion 55 is configured to stand up relative to the topsheet 10 along the rear standing line 54a due to contraction of the rear elastic member 53 in the longitudinal direction Y.

[0056] As described above, the front leakproof sheet 42 and the rear leakproof sheet 52 stand up relative to the topsheet 10 along the front standing line 44a and the rear standing line 54a extending in the longitudinal direction Y at positions spaced apart from each other in the transverse direction X. This makes it possible to prevent pet urine excreted in the absorber 30 from leaking in the transverse direction X.

[0057] As shown in Figs. 3 to 5, the main body 2 further includes a plurality of inner elastic members 61 and a plurality of outer elastic members 62. Each of the inner elastic members 61 and the outer elastic members 62 is made of a stretchable material such as rubber, stretchable nonwoven fabric, stretchable film, or spandex, and is stretchable in the longitudinal direction Y. This allows the main body 2 to be stretchable in the longitudinal direction Y, and allows the main body 2 to contract so as to follow changes in the pet's body shape and posture. This effectively improves the fit of the absorbent article for pet 1.

[0058] The inner elastic member 61 and the outer elastic member 62 extend over the entire area of ​​the main body part 2 in the longitudinal direction Y. The inner elastic member 61 and the outer elastic member 62 may extend over a part of the main body part 2 in the longitudinal direction Y. The inner elastic member 61 is disposed at a position overlapping the absorber 30 when viewed from the thickness direction Z. The outer elastic member 62 is disposed at a position not overlapping the absorber 30 when viewed from the thickness direction Z (outside the absorber 30 in the short direction X). In the example of Figs. 3 to 5, three outer elastic members 62 are disposed on the front side, and three outer elastic members 62 are disposed on the rear side. The inner elastic member 61 is disposed between the outer elastic member 62 on the front side and the outer elastic member 62 on the rear side.

[0059] The inner elastic member 61 is disposed between the topsheet 10 and the backsheet 20, and is joined to the topsheet 10 or the backsheet 20 with a hot melt adhesive while stretched in the longitudinal direction Y. The outer elastic member 62 is disposed between the topsheet 10 and one of the pair of leakage prevention gathers 40, and the backsheet 20, and is joined to the topsheet 10 and one of the pair of leakage prevention gathers 40, and the backsheet 20 with a hot melt adhesive while stretched in the longitudinal direction Y. In other words, the inner elastic member 61 and the outer elastic member 62 are disposed on the non-skin facing side Z2 of the absorbent body 30.

[0060] As shown in Figs. 1 to 3, the absorbent article for pet 1 further includes an engagement member 70. The engagement member 70 is a member that engages the first end 7 and the second end 8, and has a rectangular shape that is long in the short direction X. The engagement member 70 is provided at the first end 7, and is arranged at a position spaced apart from the first side edge 5 in the longitudinal direction Y. The engagement member 70 is provided on the outer surface of the back sheet 20. The engagement member 70 is, for example, a mechanical fastener having a large number of hooks, and is capable of engaging with the top sheet 10 from the skin-facing side Z1. The engagement member 70 may be capable of engaging with the second end 8 via another engagement member (target member) provided on the top sheet 10. The engagement member 70 may be provided on the surface of the top sheet 10 at the first end 7. In this case, the engaging member 70 may be capable of engaging with another engaging member provided on the back sheet 20 (back nonwoven fabric 22) from the non-skin facing side Z2, or may be capable of directly engaging with the back sheet 20 from the non-skin facing side Z2.

[0061] As shown in Figs. 1 to 3 and 5, the absorbent article for pet 1 further includes a first rigid sheet 81 and a second rigid sheet 82. The first rigid sheet 81 and the second rigid sheet 82 are members for imparting rigidity to the main body portion 2. The first rigid sheet 81 and the second rigid sheet 82 have a rectangular shape that is long in the short direction X, and are made of, for example, nonwoven fabric or film. Since the first rigid sheet 81 and the second rigid sheet 82 are made of nonwoven fabric, the first rigid sheet 81 and the second rigid sheet 82 can be easily formed.

[0062] The first rigid sheet 81 and the second rigid sheet 82 may be formed into a sheet shape by coating a resin such as a non-tack type hot melt adhesive or a UV curable resin. As a coating method, a method of coating with a coater may be adopted. Alternatively, another coating method (comb-shaped coating, Ω-shaped coating, spiral coating, curtain coating, etc.) may be adopted, and in this case, it is preferable that the ratio of the non-coated area to the coated area is 10% or less. When a non-tack type hot melt adhesive is used, it is preferable that the basis weight of the hot melt adhesive after curing is 15 gsm or more larger than the basis weight of the surrounding area. In this embodiment, the basis weight of the back film 21 is, for example, 15 gsm. In this case, the presence or absence of the rigid sheet can be confirmed by touch. In addition, the 180-degree peel strength (room temperature tackiness after curing) of the hot melt adhesive after curing, measured in accordance with JIS Z0237, is, for example, 1.0 N / 25 mm or less, and preferably 0 N / 25 mm. In this case, the rigid sheet is not sticky even when touched by a user. In addition, the rigid sheet is less likely to deform. As an example, the width in the short direction X of the region to which the hot melt adhesive is applied is half or more of the width in the short direction X of the absorbent body 30, and the length in the longitudinal direction Y of the region is 5 mm or more.

[0063] The first rigid sheet 81 is provided at the first end 7 and extends in the short direction X along the first side edge 5. The outer edge 81a of the first rigid sheet 81 in the longitudinal direction Y may overlap the first side edge 5 when viewed from the thickness direction Z. The outer edge 81a may be located inside the main body 2 with respect to the first side edge 5. As shown in FIG. 5, the first rigid sheet 81 is disposed between the top sheet 10 and the back sheet 20 (back film 21). This makes it difficult for the first rigid sheet 81 to peel off from the main body 2. The first rigid sheet 81 is bonded to the top sheet 10 with a hot melt adhesive H3 and to the back film 21 with a hot melt adhesive H4. The first rigid sheet 81 may be provided on the front surface of the top sheet 10 or the outer surface of the back sheet 20. The first rigid sheet 81 and a rigid sheet other than the first rigid sheet 81 may be provided on the front surface of the top sheet 10 and the outer surface of the back sheet 20, respectively. In this case, the first rigid sheet 81 can be easily recognized by the user.

[0064] The second rigid sheet 82 is provided at the second end 8 and extends in the short direction X along the second side edge 6. The outer edge 82a of the second rigid sheet 82 in the longitudinal direction Y may overlap the second side edge 6 when viewed from the thickness direction Z. The outer edge 82a may be located inside the main body 2 with respect to the second side edge 6. The second rigid sheet 82 is disposed between the top sheet 10 and the back sheet 20 (back film 21) like the first rigid sheet 81 shown in FIG. 5. This makes it difficult for the second rigid sheet 82 to peel off from the main body 2. The second rigid sheet 82 is bonded to the top sheet 10 and the back film 21 with a hot melt adhesive. The second rigid sheet 82 may be provided on the front surface of the top sheet 10 or the outer surface of the back sheet 20. The second rigid sheet 82 and a rigid sheet other than the second rigid sheet 82 may be provided on the front surface of the top sheet 10 and the outer surface of the back sheet 20, respectively. In this case, the second rigid sheet 82 can be easily recognized by the user.

[0065] Next, referring to FIG. 6, a procedure for putting the pet absorbent article 1 on a pet will be described. First, the user grasps the pet absorbent article 1 with one hand and spreads it, and presses the first end 7 of the pet absorbent article 1 against the pet's back with the hand. Next, the user holds the second end 8 of the pet absorbent article 1 with the other hand and wraps the pet absorbent article 1 around the pet's abdomen to cover it. At this time, the pet absorbent article 1 is put on so that the front leak-proof gathers 41 are positioned in front of the pet's urethral opening, and the rear leak-proof gathers 51 are positioned behind the pet's urethral opening. Next, the user pulls up the second end 8 so that the pet absorbent article 1 is in close contact with the pet's waist, and then engages the engagement member 70 of the first end 7 with the top sheet 10.

[0066] In the pet absorbent article 1, as described above, the first rigid sheet 81 and the second rigid sheet 82 are provided at the first end 7 and the second end 8, respectively. When wearing the pet absorbent article 1, the user can easily spread out the pet absorbent article 1 by grasping the first rigid sheet 81 and the second rigid sheet 82 with their hands. In addition, the first rigid sheet 81 imparts rigidity to the first end 7, and the second rigid sheet 82 imparts rigidity to the second end 8, so that when the pet absorbent article 1 is pulled in the longitudinal direction Y while grasping the first end 7 and the second end 8 with their hands, deformation of the first end 7 and the second end 8 is suppressed. This makes it possible to easily maintain the pet absorbent article 1 in an unfolded state. Therefore, according to the pet absorbent article 1, the pet absorbent article 1 can be easily worn on the pet's body.

[0067] Unlike the engaging member 70 and the target member, the first rigid sheet 81 and the second rigid sheet 82 are members that do not contribute to the engagement between the first end 7 and the second end 8. Therefore, the first rigid sheet 81 and the second rigid sheet 82 may not have protrusions such as hooks that the engaging member 70 has. For example, when the first rigid sheet 81 and the second rigid sheet 82 are provided on the front surface of the top sheet 10 or the outer surface of the back sheet 20, the user will directly grasp the first rigid sheet 81 and the second rigid sheet 82 with his or her hands. At this time, since the first rigid sheet 81 and the second rigid sheet 82 do not have protrusions, the user can easily grasp the first rigid sheet 81 and the second rigid sheet 82 with his or her hands.

[0068] The first rigid sheet 81 and the second rigid sheet 82 impart rigidity to the main body 2, thereby suppressing deformation of the absorbent article for pet 1 when worn. As a result, for example, the absorbent article for pet 1 is less likely to shift toward the hind legs of the pet when worn, so that the absorbent article for pet 1 can be suppressed from shifting.

[0069] 1 to 3, the first rigid sheet 81 extends in the short direction X along the first side edge 5, and the second rigid sheet 82 extends in the short direction X along the second side edge 6. This allows a user to easily grasp the first rigid sheet 81 and the second rigid sheet 82 with their hands when grasping the first end 7 and the second end 8 with their hands. This makes it possible to more easily spread out the pet absorbent article 1, and as a result, the pet absorbent article 1 can be more easily worn on the pet's body.

[0070] As shown in FIG. 2, the engaging member 70 is disposed at a position spaced apart from the first side edge 5. This allows the user to easily grasp the portion between the engaging member 70 and the first side edge 5 (the portion where the first rigid sheet 81 is disposed in FIG. 2) with his / her hand. Also, as shown in FIG. 2, the distance from the first side edge 5 to the first rigid sheet 81 in the longitudinal direction Y is shorter than the distance D between the engaging member 70 and the first side edge 5 in the longitudinal direction Y, and the distance from the second side edge 6 to the second rigid sheet 82 in the longitudinal direction Y is shorter than the distance D. That is, the first rigid sheet 81 is disposed at a position relatively close to the first side edge 5, and the second rigid sheet 82 is disposed at a position relatively close to the second side edge 6. This allows the user to easily grasp the first rigid sheet 81 and the second rigid sheet 82 with his / her hand when grasping the first end portion 7 and the second end portion 8 with his / her hand. Therefore, it becomes possible to more easily spread out the absorbent article for pet 1, and as a result, the absorbent article for pet 1 can be more easily worn on the body of a pet. When the outer edge 81a of the first rigid sheet 81 overlaps with the first side edge 5, the distance from the first side edge 5 to the first rigid sheet 81 is zero. Similarly, when the outer edge 82a of the second rigid sheet 82 overlaps with the second side edge 6, the distance from the second side edge 6 to the second rigid sheet 82 is zero.

[0071] 2, the first rigid sheet 81 and the second rigid sheet 82 are each disposed at a position overlapping with the center line CL of the main body part 2 in the short side direction X when viewed from the thickness direction Z. Since the first rigid sheet 81 and the second rigid sheet 82 are disposed in the central part of the main body part 2 in the short side direction X, it is easy for a user to grasp the first rigid sheet 81 and the second rigid sheet 82 with their hands. In one embodiment, the center line of each of the first rigid sheet 81 and the second rigid sheet 82 in the short side direction X coincides with the center line CL of the main body part 2.

[0072] As shown in FIG. 2, the width W1 of the first rigid sheet 81 in the short-side direction X and the width W2 of the second rigid sheet 82 in the short-side direction X are each half or more of the width W3 of the absorbent body 30 in the short-side direction X. Since the width W1 of the first rigid sheet 81 and the width W2 of the second rigid sheet 82 are relatively wide, deformation of the first end 7 and the second end 8 is more suppressed when the absorbent article for pet 1 is pulled in the longitudinal direction Y while holding the first end 7 and the second end 8 with the hand. This makes it easier to maintain the absorbent article for pet 1 in an unfolded state. In one embodiment, the width W1 of the first rigid sheet 81 and the width W2 of the second rigid sheet 82 are smaller than the width W3 of the absorbent body 30. The width W3 of the absorbent body 30 is smaller than the width W4 of the engagement member 70 in the short-side direction X. The center lines of the first rigid sheet 81 and the second rigid sheet 82 in the short-side direction X coincide with the center line of the absorbent body 30 in the short-side direction X.

[0073] As shown in FIG. 2, each of the first rigid sheet 81 and the second rigid sheet 82 extends in the short-side direction X so as to partially overlap the front leak-proof sheet 42 and the rear leak-proof sheet 52 when viewed from the thickness direction Z. That is, the width W1 of the first rigid sheet 81 and the width W2 of the second rigid sheet 82 in the short-side direction X are greater than the distance between the pair of leak-proof gathers 40 in the short-side direction X. This allows rigidity to be imparted to the portion of the main body 2 that does not overlap the front leak-proof sheet 42 and the rear leak-proof sheet 52. Therefore, deformation of the portion is suppressed, so that the pet absorbent article 1 can be more easily maintained in the unfolded state. In one embodiment, the first rigid sheet 81 and the second rigid sheet 82 are disposed between the front standing line 44a and the rear standing line 54a when viewed from the thickness direction Z. Each of the first rigid sheet 81 and the second rigid sheet 82 is disposed at a position that overlaps the first vertical fixing portion 45 and the second vertical fixing portion 46 when viewed from the thickness direction Z.

[0074] As shown in Fig. 3, each of the first rigid sheet 81 and the second rigid sheet 82 is disposed at a position overlapping the multiple inner elastic members 61 when viewed from the thickness direction Z. This makes it difficult for the first end 7 and the second end 8 to be deformed due to contraction of the multiple inner elastic members 61 (for example, the first end 7 or the second end 8 is turned up). Therefore, even when multiple inner elastic members 61 are provided, the pet absorbent article 1 can be easily maintained in an unfolded state. When the inner elastic member 61 extends over a part of the main body portion 2 in the longitudinal direction Y, each of the first rigid sheet 81 and the second rigid sheet 82 may be disposed at a position overlapping an extension line of the inner elastic member 61 when viewed from the thickness direction Z.

[0075] As shown in Figs. 1 to 3, the main body 2 includes a pair of flap portions F arranged on the outer side of the absorbent body 30 in the short-side direction X. The pair of flap portions F includes a pair of first flap portions F1 arranged on the outer side of the first rigid sheet 81 and a pair of second flap portions F2 arranged on the outer side of the second rigid sheet 82 in the short-side direction X. The first flap portion F1 is configured by a portion between the front end edge 3 and the front edge of the first rigid sheet 81, and a portion between the rear end edge 4 and the rear edge of the first rigid sheet 81. The second flap portion F2 is configured by a portion between the front end edge 3 and the front edge of the second rigid sheet 82, and a portion between the rear end edge 4 and the rear edge of the second rigid sheet 82. As shown in Fig. 3, the outer elastic members 62 extend over the entire area of ​​the pair of flap portions F in the longitudinal direction Y. That is, the multiple outer elastic members 62 are provided on the first flap portion F1 and the second flap portion F2 (overlapping the first flap portion F1 and the second flap portion F2). The multiple outer elastic members 62 impart stretchability in the longitudinal direction Y to the first flap portion F1 and the second flap portion F2.

[0076] 1, the first flap portion F1 and the second flap portion F2 may be warped toward the skin-facing side Z1 in a natural state due to the contractile force of the multiple outer elastic members 62. This allows the user to easily recognize the position of the first rigid sheet 81 located between the pair of first flap portions F1 and the position of the second rigid sheet 82 located between the pair of second flap portions F2. This allows the user to easily grasp the first rigid sheet 81 and the second rigid sheet 82 with their hands.

[0077] 1, the outer end portion (end portion on the first side edge 5 side) of the warped first flap portion F1 in the longitudinal direction Y may be located outside the inner edge 81b of the first rigid sheet 81 in the longitudinal direction Y in the natural state. Similarly, the outer end portion (end portion on the second side edge 6 side) of the warped second flap portion F2 in the longitudinal direction Y may be located outside the inner edge 82b of the second rigid sheet 82 in the longitudinal direction Y in the natural state. In this case, warping of the first flap portion F1 and the second flap portion F2 is relatively suppressed, so that it is possible to prevent the pet absorbent article 1 from being worn on the pet's body with the first flap portion F1 and the second flap portion F2 in a warped state.

[0078] As shown in FIG. 2, the length L1 of the first rigid sheet 81 in the longitudinal direction Y is different from the length L2 of the second rigid sheet 82 in the longitudinal direction Y. For example, the length L1 of the first rigid sheet 81 is shorter than the length L2 of the second rigid sheet 82. In this case, the user can easily recognize the orientation of the pet absorbent article 1. Therefore, the pet absorbent article 1 can be worn on the pet's body in the correct orientation. Note that the width W1 of the first rigid sheet 81 may be different from the width W2 of the second rigid sheet 82. For example, the width W1 of the first rigid sheet 81 may be smaller than the width W2 of the second rigid sheet 82.

[0079] The bending rigidity of each of the first rigid sheet 81 and the second rigid sheet 82 may be greater than the bending rigidity of the top sheet 10. Since the bending rigidity of each of the first rigid sheet 81 and the second rigid sheet 82 is relatively large, deformation of the portion where the first rigid sheet 81 and the second rigid sheet 82 are provided is more suppressed. Furthermore, since the bending rigidity of the top sheet 10 is relatively small, the portion of the top sheet 10 where the first rigid sheet 81 and the second rigid sheet 82 are not provided is easily deformed in response to changes in the posture and shape of the pet. Therefore, the pet absorbent article 1 can be more easily attached to the pet's body, and the fit of the pet absorbent article 1 can be improved.

[0080] The first rigid sheet 81 and the second rigid sheet 82 may be colored in a color different from that of the top sheet 10. For example, the color difference between the first rigid sheet 81 and the top sheet 10 in the L*a*b color system may be 2 or more as viewed from the skin-facing side Z1. The color difference between the second rigid sheet 82 and the top sheet 10 in the L*a*b color system may be 2 or more as viewed from the skin-facing side Z1. This allows the user to easily recognize the first rigid sheet 81 and the second rigid sheet 82. Therefore, the user can easily hold the first rigid sheet 81 and the second rigid sheet 82 with their hands.

[0081] The first rigid sheet 81 may be disposed at a position at which it at least partially overlaps the engaging member 70 when viewed from the thickness direction Z. In this case, the engaging member 70 is less likely to deform. Therefore, the engaging member 70 can be easily engaged with the second end portion 8.

[0082] The first rigid sheet 81 may be disposed at a position that does not overlap with the engaging member 70 as viewed from the thickness direction Z. In this case, the first rigid sheet 81 can be easily grasped by hand without grasping the engaging member 70 by hand. As shown in Fig. 2, in one embodiment, the first rigid sheet 81 is disposed between the first side edge 5 and the engaging member 70 as viewed from the thickness direction Z.

[0083] 2, the length L1 of the first rigid sheet 81 may be different from the length L3 of the engaging member 70 in the longitudinal direction Y. For example, the length L1 of the first rigid sheet 81 may be shorter than the length L3 of the engaging member 70 in the longitudinal direction Y. In this case, the first rigid sheet 81 and the engaging member 70 can be distinguished from each other, and as a result, the user can easily recognize the first rigid sheet 81. Therefore, the user can easily grasp the first rigid sheet 81 with his or her hand.

[0084] The tensile strength of the first rigid sheet 81 in the longitudinal direction Y may be greater than the tensile strength of the first rigid sheet 81 in the lateral direction X. The tensile strength of the second rigid sheet 82 in the longitudinal direction Y may be greater than the tensile strength of the second rigid sheet 82 in the lateral direction X. Since the tensile strengths of the first rigid sheet 81 and the second rigid sheet 82 in the longitudinal direction Y are relatively large, deformation of the first end 7 and the second end 8 is further suppressed when the pet absorbent article 1 is pulled in the longitudinal direction Y while the first end 7 and the second end 8 are respectively grasped with the hands. This makes it easier to maintain the pet absorbent article 1 in an unfolded state.

[0085] The thickness of each of the first rigid sheet 81 and the second rigid sheet 82 may be greater than the thickness of the back surface film 21. When the thickness of each of the first rigid sheet 81 and the second rigid sheet 82 is relatively large, the first rigid sheet 81 and the second rigid sheet 82 can be easily gripped by hand.

[0086] The basis weight of each of the first rigid sheet 81 and the second rigid sheet 82 may be greater than the basis weight of the back surface film 21. Since the basis weight of each of the first rigid sheet 81 and the second rigid sheet 82 is relatively large, the first rigid sheet 81 and the second rigid sheet 82 can be easily gripped by hand.

[0087] As shown in FIG. 5, the top sheet 10 may include a portion 10a that is not joined to the first rigid sheet 81. The portion 10a is a portion to which the hot melt adhesive H3 is not applied, and is a portion that overlaps with the first rigid sheet 81 in the thickness direction Z without the hot melt adhesive H3. The portion 10a is a portion that is not fixed to the first rigid sheet 81. For example, when the hot melt adhesive H3 is provided at intervals in the short direction X or the long direction Y, the portion 10a is disposed at a position corresponding to the interval. When the inner elastic member 61 contracts in the natural state, the portion 10a is bent in accordance with the deformation of the top sheet 10. As a result, the portion 10a forms a bent portion that is bent at a position that overlaps with the first rigid sheet 81 in the natural state. According to this configuration, when the first rigid sheet 81 is grasped by hand, the bent portion is caught by the hand, and the first rigid sheet 81 can be easily grasped by hand. Similarly, a part of the top sheet 10 may be folded at a position where it overlaps with the second rigid sheet 82 in the natural state to form a folded portion. Note that a part of the back nonwoven fabric 22 may be folded at a position where it overlaps with the first rigid sheet 81 or the second rigid sheet 82 in the natural state to form a folded portion.

[0088] [Variations] 7 is a plan view of a pet absorbent article 1A according to a modified example, as viewed from the skin-facing side Z1. The pet absorbent article 1A differs from the embodiment shown in FIG.

[0089] The main body portion 2 includes a plurality of openings 15 provided at the first end portion 7, through which the pet's tail cannot be inserted when the pet absorbent article 1A is worn by the pet, and which improve the breathability of the internal space facing the top sheet 10. The plurality of openings 15 penetrate the main body portion 2 along the thickness direction Z. The plurality of openings 15 are arranged so as to sandwich the center line CL of the main body portion 2 between the absorbent body 30 and the engaging member 70 when viewed from the thickness direction Z.

[0090] The multiple openings 15 are arranged in a position aligned with the first rigid sheet 81 in the longitudinal direction Y as viewed from the thickness direction Z. This suppresses deformation of the multiple openings 15. For example, as shown in FIG. 7, when the first rigid sheet 81 extends along the short-side direction X, the rigidity of the first rigid sheet 81 suppresses deformation or contraction of the main body 2 in the short-side direction X. Therefore, since it is possible to suppress closure of the multiple openings 15 due to deformation or contraction of the main body 2 in the short-side direction X, it is possible to effectively improve the breathability of the absorbent article for pets 1A. The multiple openings 15 may be provided at the second end 8. The main body 2 may include multiple opening forming portions for forming the multiple openings 15. The opening forming portions are, for example, multiple cut portions provided in the main body 2. The multiple openings 15 are formed by opening the cut portions when the absorbent article for pets 1A is used.

[0091] Although various embodiments and modifications of the absorbent article for pets have been described above, the present invention is not limited to the above-mentioned embodiments and modifications, and various modifications can be made without departing from the spirit of the invention. In other words, it should be noted that the above-mentioned embodiments and modifications are intended to be illustrative and do not limit the scope of the present invention.

[0092] For example, in each of the above-mentioned pet absorbent articles 1, 1A, the first rigid sheet 81 and the second rigid sheet 82 are provided at the first end 7 and the second end 8, respectively, but each of the pet absorbent articles 1, 1A may not have one of the first rigid sheet 81 and the second rigid sheet 82. The above-mentioned various embodiments and modified examples can be combined to the extent that no contradiction occurs.
