DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] [Overview of the embodiment of the present disclosure] An overview of the embodiments of the present disclosure will be described with reference to the following clauses. The present disclosure includes any combination of the following clauses.

[0010] (Clause 1) According to one embodiment, a pet absorbent article is worn by wrapping it around the waist of a pet. The pet absorbent article includes a main body having a horizontally elongated shape having a longitudinal direction and a lateral direction, the main body including a top sheet arranged on the skin-facing side, a back sheet arranged on the non-skin-facing side, and an absorbent arranged between the top sheet and the back sheet, the main body having a first portion arranged on one longitudinal side of a center line of the main body in the longitudinal direction and a second portion arranged on the other longitudinal side of the center line of the main body in the longitudinal direction, an engagement portion provided on the first portion of the main body for engaging the first portion and the second portion, a pair of leakproof sheets each capable of standing upright 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 a pair of outer elastic members provided outside the pair of standing lines in the lateral direction and stretchable in the longitudinal direction, the main body further including one or more inner elastic members provided inside the pair of standing lines in the lateral direction and imparting stretchability to the main body.

[0011] In the above embodiment, the pair of outer elastic members contract in the longitudinal direction, causing the pair of leakproof sheets to stand up against the top sheet and to come into close contact with the pet's body. In addition, one or more inner elastic members provided inside the pair of standing lines in the lateral direction contract to follow changes in the pet's body shape and posture, improving the fit of the pet absorbent article. As a result, the formation of a gap between the pet absorbent article and the pet's body is suppressed, and urine leakage can be effectively suppressed.

[0012] (Clause 2) In the absorbent article for pets described in clause 1, the one or more inner elastic members may be stretchable in the longitudinal direction. In this case, the one or more inner elastic members contract so as to follow changes in the pet's body shape and posture in the longitudinal direction, thereby improving the fit of the absorbent article for pets. As a result, urine leakage can be effectively suppressed.

[0013] (Clause 3) In the absorbent article for pets described in clause 2, one or more inner elastic members may extend over the entire area of ​​the main body in the longitudinal direction. In this case, the main body stretches over the entire area in the longitudinal direction, so that the absorbent article for pets can fit the body of the pet over the entire area of ​​the pet's waist when the absorbent article for pets is worn. This can prevent the absorbent article for pets from shifting, and more effectively prevent urine leakage.

[0014] (Clause 4) In the absorbent article for pets described in any one of clauses 1 to 3, the engagement portion may be provided on the front surface of the top sheet and may be engageable with the back sheet. In this case, the engagement portion can be used to easily put the absorbent article for pets on a pet.

[0015] (Clause 5) In the absorbent article for pets described in clause 4, the first portion may include a stretchable region including one or more inner elastic members, the second portion may include a non-stretchable region not including one or more inner elastic members, and the contraction rate of the first portion may be higher than that of the second portion. In this case, the second portion having a relatively lower contraction rate may be placed against the body of the pet to align the absorbent article for pets. In addition, when the first portion is engaged with the second portion, the first portion having a relatively higher contraction rate contracts, thereby reducing looseness of the absorbent article for pets when worn. This improves the fit of the absorbent article for pets.

[0016] (Clause 6) In the absorbent article for pets described in any one of clauses 1 to 5, the center of one or more inner elastic members in the longitudinal direction may be disposed on one side of the center line of the absorbent body in the longitudinal direction. In this case, the region on one side of the main body part relative to the center line of the absorbent body is more likely to stretch than the region on the other side of the main body part. This makes it easier to align the absorbent article for pets by placing the region on the other side of the main body part against the pet's body. In addition, when the first part is engaged with the second part, the region on one side of the main body part contracts, thereby reducing looseness of the absorbent article for pets when worn.

[0017] (Clause 7) In the absorbent article for pets described in any one of clauses 1 to 3, the engagement portion may be provided on the outer surface of the back sheet and be engageable with the top sheet. In this case, the engagement portion can be used to easily put the absorbent article for pets on a pet.

[0018] (Article 8) In the absorbent article for pets described in clause 7, the first portion may include a non-elastic region that does not include one or more inner elastic members, the second portion may include an elastic region that includes one or more inner elastic members, and the contraction rate of the second portion may be higher than that of the first portion. In this case, the first portion, which has a relatively low contraction rate, may be placed against the pet's body to align the absorbent article for pets. In addition, when the second portion is engaged with the first portion, the second portion, which has a relatively high contraction rate, may contract, thereby reducing looseness of the absorbent article for pets when worn. This can improve the fit of the absorbent article for pets.

[0019] (Article 9) In the absorbent article for pets described in clause 7 or 8, the center of one or more inner elastic members in the longitudinal direction may be disposed on the other longitudinal side of the center line of the absorbent body in the longitudinal direction. In this case, the region on the other side of the main body part with respect to the center line of the absorbent body is more elastic than the region on one side of the main body part. This makes it easy to align the absorbent article for pets by placing the region on one side of the main body part against the pet's body. In addition, since the region on the other side of the main body part contracts when the first part and the second part engage with each other, loosening of the absorbent article for pets when worn is reduced.

[0020] (Article 10) In the absorbent article for pets described in any one of clauses 1 to 9, the one or more inner elastic members may overlap the engaging portion when viewed in the thickness direction of the main body. In this case, the engaging portion is pulled by the contractile force of the inner elastic member, thereby firmly engaging the first portion and the second portion. This prevents the absorbent article for pets from being unintentionally detached.

[0021] (Article 11) In the absorbent article for pets described in any one of clauses 1 to 9, the one or more inner elastic members may not overlap the engagement portion when viewed in the thickness direction of the main body. By arranging the one or more elastic members so as not to overlap the engagement portion, the engagement portion is prevented from being deformed in a wavy manner due to the contractile force of the inner elastic member. Therefore, the engagement between the first part and the second part is prevented from being unintentionally released.

[0022] (Article 12) In the absorbent article for pets described in any one of clauses 1 to 11, the one or more inner elastic members may not overlap the absorbent body when viewed in the thickness direction of the main body portion. In this case, deformation of the absorbent body due to expansion and contraction of the inner elastic members can be prevented.

[0023] (Article 13) In the absorbent article for pets described in any one of clauses 1 to 11, the one or more inner elastic members may overlap the absorbent body when viewed in the thickness direction of the main body. In this case, even if urine is absorbed by the absorbent body, the absorbent body is lifted by the contractile force of the inner elastic members, and sagging of the absorbent body is suppressed. Thus, the fit of the absorbent article for pets can be maintained.

[0024] (Article 14) In the absorbent article for pets described in any one of clauses 1 to 13, each of the pair of outer elastic members may extend continuously in the longitudinal direction. In this case, the contractile force of the pair of outer elastic members allows the absorbent article for pets to fit the body of the pet.

[0025] (Article 15) In the absorbent article for pets described in any one of clauses 1 to 13, each of the pair of outer elastic members may be formed discontinuously. In this case, the outer elastic members partially contract in the longitudinal direction, so that pressure on the pet's body by the pair of outer elastic members can be reduced.

[0026] (Article 16) In the absorbent article for pets described in any one of clauses 1 to 15, the pair of leakproof sheets includes a front leakproof sheet capable of standing along a first standing line of the pair of standing lines and a rear leakproof sheet capable of standing along a second standing line of the pair of standing lines, and the maximum standing height of the front leakproof sheet based on the main body may be higher than the maximum standing height of the rear leakproof sheet based on the main body. In this case, when the absorbent article for pets is worn so that the front leakproof sheet is positioned on the pet's head side, the front leakproof sheet can block the pet's urine, thereby effectively suppressing urine leakage.

[0027] (Article 17) In the absorbent article for pets according to any one of clauses 1 to 16, the main body may include a plurality of inner elastic members arranged along the short side direction. In this case, each inner elastic member contracts to follow changes in the pet's body shape and posture, thereby improving the fit of the absorbent article for pets.

[0028] (Article 18) According to another embodiment, a pet absorbent article is worn by wrapping it around the waist of a pet. The pet absorbent article is a main body part having a horizontally elongated shape having a longitudinal direction and a lateral direction, the main body part including a top sheet arranged on the skin-facing side, a back sheet arranged on the non-skin-facing side, and an absorbent body arranged between the top sheet and the back sheet, the main body part having a first part arranged on one side in the longitudinal direction with respect to a center line of the main body part in the longitudinal direction and a second part arranged on the other side in the longitudinal direction with respect to the center line of the main body part in the longitudinal direction, an engagement part provided on the first part of the main body part and engaging the first part and the second part, and a pair of outer elastic members provided outside the absorbent body in the lateral direction and stretchable in the longitudinal direction, the main body part further includes one or more inner elastic members arranged on the non-skin-facing side of the top sheet and imparting stretchability to the main body part, the one or more inner elastic members being arranged inside the pair of outer elastic members in the lateral direction and overlapping the engagement part when viewed in the thickness direction of the main body part.

[0029] In the pet absorbent article according to the above aspect, the one or more inner elastic members contract to follow changes in the pet's body shape and posture, improving the fit of the pet absorbent article, thereby preventing gaps from forming between the pet absorbent article and the pet's body, and effectively preventing urine leakage.

[0030] (Article 19) In the absorbent article for pets described in clause 18, when the engaging portion is divided into three equal regions in the lateral direction, the regions being a front region, a central region, and a rear region, starting from one side in the lateral direction, one or more inner elastic members may overlap the central region when viewed in the thickness direction of the main body portion. In this case, the fit of the absorbent article for pets can be improved.

[0031] (Article 20) A packaging body according to one embodiment contains the absorbent article for pets described in any one of clauses 1 to 17. The main body of this absorbent article for pets includes a front flap portion and a rear flap portion arranged on the outer side of the absorbent body in the short side direction, the pair of leakproof sheets includes a front leakproof sheet that can stand along a first standing line of the pair of standing lines and a rear leakproof sheet that can stand along a second standing line of the pair of standing lines, and the absorbent article for pets is contained in the packaging body with the main body folded in thirds or fourths in the long side direction after the front flap portion is folded inward along a fold line extending in the long side direction so that the inner edge in the short side direction of the front leakproof sheet is exposed.

[0032] In the above-mentioned embodiment, when the pet absorbent article folded in three or four is unfolded in the longitudinal direction, the inner edge of the front leakproof sheet in the lateral direction is exposed. Therefore, even when the pet absorbent article is worn without unfolding the front flap portion, the front leakproof sheet comes into contact with the pet's body. Therefore, the front leakproof sheet can prevent urine leakage.

[0033] (Article 21) In the packaging described in clause 20, the rear flap portion does not have to be folded inward in the short direction. By folding the front flap portion and not folding the rear flap portion, a user can easily recognize the front and rear directions of the absorbent article for pets when removing the absorbent article for pets from the packaging. This makes it easier to put the absorbent article for pets on the pet in the correct orientation.

[0034] [Examples of the embodiments of the present disclosure] 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.

[0035] Hereinafter, an absorbent article for pets according to one embodiment will be described. Fig. 1 is a perspective view showing a pet absorbent article 1 according to one embodiment. Fig. 2 is a plan view showing the absorbent article for pets 1 from the skin side Z1. Fig. 3 is a cross-sectional view of the absorbent article for pets 1 taken along line AA in Fig. 1. Fig. 4 is a cross-sectional view of the absorbent article for pets 1 taken along line BB in Fig. 1. Fig. 5 is a cross-sectional view of the absorbent article for pets 1 taken along line CC in Fig. 1. The absorbent article for pets 1 shown in Figs. 1 to 5 is a disposable diaper for pets that absorbs urine of pets.

[0036] 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. FIG. 2 shows 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.

[0037] 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.

[0038] 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 four corners of the main body 2 are cut so that the width of the main body 2 in the short side direction X is narrowed. The four corners of the main body 2 do not have to be cut. 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 on 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. In addition, the main body 2 has a first portion 2A arranged on one side of the longitudinal direction Y with respect to the center line P1 of the main body 2 in the longitudinal direction Y, and a second portion 2B arranged on the other side of the longitudinal direction Y with respect to the center line P1 of the main body 2 in the longitudinal direction Y.

[0039] As shown in Figs. 1 to 5, the main body 2 includes a top sheet 15, a back sheet 20, an absorbent 30, and a pair of leak-proof sheets 40. The top sheet 15 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 15 has liquid permeability that allows, for example, pet urine to pass through to the absorbent 30 side. The top sheet 15 is positioned approximately at the center in the short direction X. Examples of nonwoven fabric constituting the top sheet 15 include air-through nonwoven fabric, spunbond nonwoven fabric, and point-bond nonwoven fabric. The top sheet 15 is bonded to the back sheet 20 and the absorbent 30 with, for example, a hot melt adhesive.

[0040] The back sheet 20 constitutes the surface of the main body 2 that is positioned on the outside when worn, and is disposed on the non-skin-facing side Z2. The back sheet 20 includes a liquid-impermeable back film 21 and a back nonwoven fabric 22 disposed on the non-skin-facing side Z2 of the back film 21. In the short direction X, the back film 21 has substantially the same width as the back nonwoven fabric 22. Note that, in the short direction X, the width of the back film 21 may be narrower than the width of the back nonwoven fabric 22, and the back nonwoven fabric 22 may extend beyond the back film 21 on both sides in the short direction X. The back nonwoven fabric 22 constitutes the outermost layer of the pet absorbent article 1. The back film 21 is bonded to the back nonwoven fabric 22 and the absorbent body 30 by, for example, a hot melt adhesive.

[0041] The absorbent body 30 is disposed between the top sheet 15 and the back sheet 20. The absorbent body 30 is located approximately in the center of the main body portion 2, and absorbs pet urine. The absorbent body 30 has a generally rectangular shape extending in the longitudinal direction Y.

[0042] The main body 2 includes a first end 7 disposed on one side in the longitudinal direction Y, a second end 8 disposed on the other end side in the longitudinal direction Y, and a central portion 9 disposed between the first end 7 and the second end 8. In one embodiment, the first end 7 is a region located between the absorbent 30 and the first side edge 5 in the longitudinal direction Y. The second end 8 is a region located between the absorbent 30 and the second side edge 6 in the longitudinal direction Y. The central portion 9 is a region located between the first end 7 and the second end 8 in the longitudinal direction Y. In one embodiment, the width of the first end 7 in the lateral direction X is narrowed as it approaches the first side edge 5, and the width of the second end 8 in the lateral direction X is narrowed as it approaches the second side edge 6. The narrowing of the widths of the first end 7 and the second end 8 makes it easier for a user to grip the first end 7 and the second end 8. The first end 7 is part of the first portion 2A and the second end 8 is part of the second portion 2B.

[0043] The main body portion 2 includes a front flap portion 11 and a rear flap portion 12 that are arranged outside the absorbent body 30 in the short direction X. The front flap portion 11 is arranged along the front edge 3, and the rear flap portion 12 is arranged along the rear edge 4.

[0044] In one embodiment, the absorbent body 30 includes an absorbent core containing absorbent pulp and a polymeric absorbent (SAP), 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 for the absorbent core. For example, starch-based, acrylic acid-based, or amino acid-based particulate or fibrous polymer is used as the polymeric absorbent. The absorbent body 30 may be a SAP sheet that does not contain pulp and is mainly composed of SAP.

[0045] The pair of leak-proof sheets 40 are provided on the top sheet 15 and are spaced apart from each other in the short-side direction X. The pair of leak-proof sheets 40 are provided so as to cover both sides of the top sheet 15 in the short-side direction X from the skin-facing side Z1, and extend in the long-side direction Y over the entire length of the main body 2. The pair of leak-proof sheets 40 are partially joined to the top sheet 15 or the back sheet 20 on the outer side of the absorber 30 in the short-side direction X. The pair of leak-proof sheets 40 stand up against the top sheet 15 to prevent pet urine excreted in the absorber 30 from leaking in the short-side direction X. The pair of leak-proof sheets 40 include a front leak-proof sheet 41 provided along the front edge 3 and a rear leak-proof sheet 51 provided along the rear edge 4. The pair of leak-proof sheets 40 may be formed by rolling back the back nonwoven fabric 22 toward the top sheet 15 on the outer side of the main body 2 in the short-side direction X. In this case, a part of the back surface nonwoven fabric 22 rolled back towards the top sheet 15 constitutes a pair of leak-proof sheets 40 , and the other part of the back surface nonwoven fabric 22 constitutes the back surface sheet 20 of the main body portion 2 .

[0046] In one embodiment, the front leakproof sheet 41 includes a side sheet 42 partially fixed to the top sheet 15 or the back sheet 20, and a first elastic member 43 joined to the side sheet 42. The rear leakproof sheet 51 includes a side sheet 52 partially fixed to the top sheet 15 or the back sheet 20, and a first elastic member 53 joined to the side sheet 52. Each of the pair of side sheets 42, 52 is made of a nonwoven fabric having water repellency or hydrophobicity. For example, the side sheets 42, 52 are made of a spunlace nonwoven fabric, a spunbond nonwoven fabric, a thermal bond nonwoven fabric, a meltblown nonwoven fabric, an SMS nonwoven fabric, a needle punch nonwoven fabric, an air-through nonwoven fabric, or the like.

[0047] Each of the pair of side sheets 42, 52 has a vertically elongated shape that is long in the longitudinal direction Y, and extends in the longitudinal direction Y over the entire length of the main body 2. As shown in Figs. 3 to 5, the outer edge of the front leakproof sheet 41 in the lateral direction X coincides with the outer edges of the back surface film 21 and the back surface nonwoven fabric 22 in the lateral direction X, and constitutes the front edge 3 together with the outer edges of the back surface film 21 and the back surface nonwoven fabric 22. The outer edge of the rear leakproof sheet 51 in the lateral direction X coincides with the outer edges of the back surface film 21 and the back surface nonwoven fabric 22 in the lateral direction, and constitutes the rear edge 4 together with the outer edges of the back surface film 21 and the back surface nonwoven fabric 22.

[0048] 2 to 5, the side sheet 42 includes a fixed portion 45 joined to the top sheet 15 or the back sheet 20, and an upright portion 46 not joined to the top sheet 15. At the boundary between the fixed portion 45 and the upright portion 46, a first upright line 45a, a second upright line 45b, and a third upright line 45c are formed.

[0049] The first standing line 45a is disposed between the center line P2 in the short-side direction X of the main body portion 2 and the front end edge 3, and extends in the longitudinal direction Y. For example, the first standing line 45a is disposed between the front edge of the absorber 30 and the front end edge 3. The first standing line 45a is a boundary line between the fixed portion 45 and the standing portion 46 in the short-side direction X, and serves as a standing fulcrum with the standing portion 46 in the short-side direction X. The first standing line 45a may partially overlap the absorber 30 when viewed from the thickness direction Z.

[0050] The second standing line 45b is disposed between the center line P1 and the first side edge 5 in the longitudinal direction Y of the main body 2, and extends in the short direction X. For example, the second standing line 45b is disposed closer to the center line P1 than the edge of the absorber 30 on the first side edge 5 side in the longitudinal direction Y. The second standing line 45b is a boundary line between the fixed part 45 and the standing part 46 in the longitudinal direction Y, and serves as a standing fulcrum with the standing part 46 in the longitudinal direction Y. Note that the second standing line 45b may be disposed closer to the first side edge 5 than the edge of the absorber 30 on the first side edge 5 side in the longitudinal direction Y.

[0051] The third standing line 45c is disposed between the center line P1 and the second side edge 6 in the longitudinal direction Y of the main body portion 2, and extends in the short direction X. For example, the third standing line 45c is disposed closer to the center line P1 than the edge on the second side edge 6 side of the absorber 30 in the longitudinal direction Y. The third standing line 45c is a boundary line between the fixed portion 45 and the standing portion 46 in the longitudinal direction Y, and serves as a standing fulcrum with the standing portion 46 in the longitudinal direction Y. Note that the third standing line 45c may be disposed closer to the second side edge 6 than the edge on the second side edge 6 side of the absorber 30 in the longitudinal direction Y.

[0052] As described above, the first region 42A of the side sheet 42 on the first side edge 5 side of the second standing line 45b is a part of the fixing portion 45, and is joined to the main body 2 with a hot melt adhesive in a state where it is leaning inward in the short side direction X. Similarly, the second region 42B of the side sheet 42 on the second side edge 6 side of the third standing line 45c is a part of the fixing portion 45, and is joined to the main body 2 with a hot melt adhesive in a state where it is leaning inward in the short side direction X. Therefore, as shown in Figures 3 and 5, the first region 42A and the second region 42B of the side sheet 42 are fixed to the main body 2 and are non-standing regions that do not stand up.

[0053] In contrast, the standing portion 46 is disposed between the first region 42A and the second region 42B, and is an upstanding region that is not connected to the main body portion 2. The standing portion 46 is disposed on the inside of the first standing line 45a in the short-side direction X, and can stand along the first standing line 45a between the first region 42A and the second region 42B. Since the first region 42A and the second region 42B of the side sheet 42 are joined to the main body portion 2, the standing portion 46 is folded inward in the short-side direction X in the unfolded state.

[0054] The inner portions of the standing portions 46 in the short direction X are folded back, and the first elastic members 43 are disposed between the folded back standing portions 46. Therefore, as shown in Fig. 2, the first elastic members 43 of the front leakproof sheet 41 are disposed along the inner edges 44a of the standing portions 46. The first elastic members 43 are joined to the side sheets 42 in a state stretched in the longitudinal direction Y. The first elastic members 43 are made of a stretchable material, such as rubber or spandex, that is shrinkable in the longitudinal direction.

[0055] 4, when in a natural state, the first elastic members 43 contract in the longitudinal direction Y, causing the standing portions 46 of the side sheets 42 to stand up along the first standing lines 45a outside the lateral direction X of the absorber 30. The standing portions 46 of the front leakproof sheet 41 stand up, thereby preventing pet urine from leaking along the surface of the topsheet 15 to the front.

[0056] The side sheet 52 includes a fixed portion 55 joined to the top sheet 15 or the back sheet 20, and an upright portion 56 not joined to the top sheet 15. At the boundary between the fixed portion 55 and the upright portion 56, a fourth upright line 55a, a fifth upright line 55b, and a sixth upright line 55c are formed.

[0057] The fourth standing line 55a is disposed between the center line P2 in the short-side direction X of the main body portion 2 and the rear end edge 4, and extends in the longitudinal direction Y. For example, the fourth standing line 55a is disposed between the end edge of the absorber 30 on the rear side and the rear end edge 4. The fourth standing line 55a is a boundary line between the fixed portion 55 and the standing portion 56 in the short-side direction X, and serves as a standing fulcrum with the standing portion 56 in the short-side direction X. The fourth standing line 55a may partially overlap the absorber 30 when viewed from the thickness direction Z.

[0058] The fifth standing line 55b is disposed between the center line P1 and the first side edge 5 in the longitudinal direction Y of the main body 2, and extends in the short direction X. For example, the fifth standing line 55b is disposed closer to the center line P1 than the edge on the first side edge 5 side of the absorber 30 in the longitudinal direction Y. The fifth standing line 55b is a boundary line between the fixed part 55 and the standing part 56 in the longitudinal direction Y, and serves as a standing fulcrum with the standing part 56 in the longitudinal direction Y. The fifth standing line 55b may be disposed closer to the first side edge 5 than the edge on the first side edge 5 side of the absorber 30 in the longitudinal direction Y.

[0059] The sixth standing line 55c is disposed between the center line P1 and the second side edge 6 in the longitudinal direction Y of the main body 2, and extends in the short direction X. For example, the sixth standing line 55c is disposed closer to the center line P1 than the edge on the second side edge 6 side of the absorber 30 in the longitudinal direction Y. The sixth standing line 55c is a boundary line between the fixed part 55 and the standing part 56 in the longitudinal direction Y, and serves as a standing fulcrum with the standing part 56 in the longitudinal direction Y. The sixth standing line 55c may be disposed closer to the second side edge 6 than the edge on the second side edge 6 side of the absorber 30 in the longitudinal direction Y.

[0060] As described above, the first region 52A of the side sheet 52 on the first side edge 5 side of the fifth rising line 55b is a part of the fixing part 55, and is joined to the main body 2 with a hot melt adhesive in a state where it is folded back outward in the short-side direction X. More specifically, the first region 52A is folded back outward in the short-side direction X along an extension line of the fourth rising line 55a, and the lower layer of the folded back first region 52A is joined to the top sheet 15 or the back sheet 20, and the upper layer of the folded back first region 52A is joined to the lower layer. Similarly, the second region 52B of the side sheet 52 on the second side edge 6 side of the sixth rising line 55c is a part of the fixing part 55, and is joined to the main body 2 with a hot melt adhesive in a state where it is folded back outward in the short-side direction X. More specifically, the second region 52B is folded back outward in the short-side direction X along an extension of the fourth standing line 55a, and the lower layer of the folded back second region 52B is joined to the top sheet 15 or the back sheet 20, and the upper layer of the folded back second region 52B is joined to the lower layer. Therefore, as shown in Figures 3 and 5, the first region 52A and the second region 52B of the side sheet 52 are fixed to the main body portion 2 and are non-standing regions that do not stand up.

[0061] In contrast, the standing portion 56 is an upright region that is disposed between the first region 52A and the second region 52B and is not connected to the main body 2. The standing portion 56 is disposed inside the fourth standing line 55a in the short-side direction X and can stand along the fourth standing line 55a between the first region 52A and the second region 52B. Since the first region 52A and the second region 52B of the side sheet 52 are joined to the main body 2 in a state where they are folded back outward in the short-side direction X, the standing portion 56 is collapsed outward in the short-side direction X in the unfolded state. By collapsing the standing portion 56 outward in the short-side direction X in the unfolded state, the first elastic member 53 of the rear leakproof sheet 51 is prevented from rubbing against the genitals of the pet when the pet absorbent article 1 is worn. Each of the first region 52A and the second region 52B may be joined to the main body 2 without being folded back outward in the short-side direction X. In this case, the standing portions 56 fall inward in the short side direction X in the unfolded state.

[0062] The inner portions of the standing portions 56 in the short direction X are folded back, and the first elastic members 53 are disposed between the folded back standing portions 56. Therefore, as shown in Fig. 2, the first elastic members 53 of the rear leakproof sheet 51 are disposed along the inner edges 54a of the standing portions 56. The first elastic members 53 are joined to the side sheets 52 in a state stretched in the longitudinal direction Y. The first elastic members 53 are made of a stretchable material, such as rubber or spandex, that is shrinkable in the longitudinal direction.

[0063] 4, when the first elastic members 53 are in a natural state, the standing portions 56 of the side sheets 52 stand up along the fourth standing lines 55a outside the short-side direction X of the absorber 30 as a result of the first elastic members 53 contracting in the longitudinal direction Y. As the standing portions 56 of the rear leakproof sheet 51 stand up, pet urine is prevented from leaking along the surface of the topsheet 15 to the rear side.

[0064] 4, the maximum standing height H1 of the front leakproof sheet 41 based on the main body 2 may be higher than the maximum standing height H2 of the rear leakproof sheet 51 based on the main body 2. The maximum standing height H1 corresponds to the height of the top of the front leakproof sheet 41 based on the main body 2 when the front leakproof sheet 41 stands vertically relative to the main body 2. In other words, the maximum standing height H1 can be said to be the length along the surface of the front leakproof sheet 41 from the first standing line 45a to the top of the standing portion 46 in a cross section taken along the short direction X. Similarly, the maximum standing height H2 corresponds to the height of the top of the rear leakproof sheet 51 based on the main body 2 when the rear leakproof sheet 51 stands vertically relative to the main body 2. In other words, the maximum standing height H2 can be said to be the length along the surface of the rear leakproof sheet 51 from the fourth standing line 55a to the top of the standing portion 56 in a cross section along the short direction X. By making the maximum standing height H1 higher than the maximum standing height H2, when the pet absorbent article 1 is worn so that the front leakproof sheet 41 is positioned on the pet's head side, urine discharged with force from the pet can be blocked by the front leakproof sheet 41, so that urine leakage can be effectively suppressed. Note that the maximum standing height H2 of the rear leakproof sheet 51 may be higher than the maximum standing height H1 of the front leakproof sheet 41. In this case, urine flowing to the rear side can be blocked by the rear leakproof sheet 51, so that urine leakage can be effectively suppressed.

[0065] The main body 2 further includes a pair of outer elastic members 61, 62 stretchable in the longitudinal direction Y, and a plurality of inner elastic members 63 stretchable in the longitudinal direction Y. The outer elastic members 61, 62 and the longitudinal direction Y are disposed between the top sheet 15 and the back sheet 20. The outer elastic members 61, 62 and the inner elastic member 63 stretch so as to follow changes in the pet's body shape and posture in the longitudinal direction Y (for example, when the pet twists its body). Each of the outer elastic members 61, 62 and the inner elastic member 63 is made of a stretchable material such as rubber, stretchable nonwoven fabric, stretchable film, or spandex.

[0066] The outer elastic member 61 is provided outside the first standing line 45a in the short direction X and extends along the front edge 3. The outer elastic member 62 is provided outside the fourth standing line 55a in the short direction X and extends along the rear edge 4. Each of the outer elastic members 61, 62 extends continuously in the longitudinal direction Y between the first end 7 and the second end 8. The main body 2 may include a plurality of outer elastic members 61 and a plurality of outer elastic members 62. The numbers of the outer elastic members 61, 62 may be different from each other.

[0067] The outer elastic members 61, 62 are disposed, for example, between the pair of leakproof sheets 40 and the backsheet 20. The outer elastic members 61, 62 are joined to the leakproof sheet 40 and the backsheet 20 with a hot melt adhesive in a state stretched in the longitudinal direction Y. That is, the outer elastic members 61, 62 are disposed on the non-skin-facing side Z2 of the pair of leakproof sheets 40. Each of the outer elastic members 61, 62 may overlap at least one of the first end portion 7 and the second end portion 8 as viewed from the thickness direction Z, or may not overlap both the first end portion 7 and the second end portion 8 as viewed from the thickness direction Z.

[0068] The inner elastic members 63 are provided on the inside of the first upright line 45a and the fourth upright line 55a in the short direction X, and provide elasticity to the main body 2. In one embodiment, the inner elastic members 63 are provided at the first end 7 of the main body 2, and provide elasticity to the first end 7. More specifically, the inner elastic members 63 extend between the absorber 30 and an engagement portion 70 described later. Therefore, the center P3 of the inner elastic members 63 in the longitudinal direction Y is disposed on the first side edge 5 side with respect to the center line P4 of the absorber 30 in the longitudinal direction Y. As described above, the inner elastic members 63 do not overlap the absorber 30 when viewed from the thickness direction Z, and therefore deformation of the absorber 30 due to the contraction force of the inner elastic members 63 can be prevented.

[0069] The multiple inner elastic members 63 may be arranged at equal intervals along the short direction X between the first standing line 45a and the fourth standing line 55a. The number of the inner elastic members 63 is any number equal to or greater than 1. The inner elastic members 63 are arranged on the non-skin facing side Z2 of the top sheet 15. For example, the inner elastic members 63 are arranged between the top sheet 15 and the back film 21, and are joined to the top sheet 15 and the back film 21 with a hot melt adhesive in a state in which they are stretched in the longitudinal direction Y. By arranging the inner elastic members 63 on the non-skin facing side Z2 of the top sheet 15, the inner elastic members 63 can be prevented from directly contacting the pet's body when the pet absorbent article 1 is worn, and therefore the wearing comfort of the pet absorbent article 1 can be improved.

[0070] The multiple inner elastic members 63 may extend in the short side direction X between the first standing line 45a and the fourth standing line 55a and be stretchable in the short side direction X. In this case, the main body 2 can be stretched to follow changes in the pet's body shape and posture in the short side direction X (for example, when the pet stretches its body), thereby improving the fit of the absorbent article for pet 1.

[0071] The outer elastic members 61, 62 and the inner elastic member 63 may be joined to the top sheet 15 or the back sheet 20 without using a hot melt adhesive. For example, the outer elastic members 61, 62 and the inner elastic member 63 may be joined to the top sheet 15 or the back sheet 20 by sonic processing.

[0072] The first portion 2A of the main body 2 includes a stretchable region R1 including the inner elastic member 63, and the second portion 2B of the main body 2 includes a non-stretchable region R2 not including the inner elastic member 63. In the embodiment shown in FIG. 2, the first end 7 includes the stretchable region R1, and the second end 8 includes the non-stretchable region R2. Therefore, the contraction rate of the first portion 2A is higher than that of the second portion 2B. That is, the contraction rate of the first end 7 is higher than that of the second end 8. When the length in the longitudinal direction Y of the first portion 2A or the second portion 2B in the natural state is L1, and the length in the longitudinal direction Y of the first portion 2A or the second portion 2B in the unfolded state is L2, the contraction rate [%] is expressed as (L2-L1) / L2×100. Note that some of the inner elastic members 63 may extend halfway through the second portion 2B, and only a part of the second portion 2B may constitute the non-stretchable region R2. In one embodiment, the inner elastic member 63 may be provided at both the first end portion 7 and the second end portion 8. In this case, the first portion 2A and the second portion 2B may have the same contraction rate.

[0073] The pet absorbent article 1 further includes an engagement portion 70. The engagement portion 70 is a member that engages the first portion 2A and the second portion 2B. As shown in Figs. 1 and 2, the engagement portion 70 has a rectangular shape that is long in the short direction X, and is provided at a first end portion 7 of the first portion 2A. The engagement portion 70 is provided on the surface of the top sheet 15. The engagement portion 70 is, for example, a mechanical fastener having a large number of hooks, and is capable of engaging with the back sheet 20 from the non-skin facing side Z2.

[0074] In one embodiment, a target portion 71 is provided on the outer surface of the back sheet 20 of the second portion 2B. The target portion 71 may overlap the absorbent body 30 and the second end portion 8 when viewed from the thickness direction Z. When the pet absorbent article 1 is worn, the engagement portion 70 engages with the back sheet 20 via the target portion 71 provided on the back sheet 20. The engagement portion 70 may be capable of directly engaging with the back sheet 20.

[0075] When viewed from the thickness direction Z, the multiple inner elastic members 63 may be arranged so as not to overlap the engagement portion 70 and the target portion 71. This prevents the engagement portion 70 and the target portion 71 from being deformed in a wavy manner due to the contraction force of the multiple inner elastic members 63.

[0076] The absorbent article for pets 1 configured as above can be attached to a pet as follows. First, the user presses the second end 8 of the absorbent article for pets 1 against the back of the pet and holds the vicinity of the second end 8 with one hand. Next, the user holds the first end 7 of the absorbent article for pets 1 with the other hand and wraps the absorbent article for pets 1 around the pet's abdomen to cover it. At this time, the absorbent article for pets 1 is attached so that the front leakproof sheet 41 is positioned in front of the urethral opening of the pet and the rear leakproof sheet 51 is positioned behind the urethral opening of the pet. Next, the user pulls up the first end 7 so that the absorbent article for pets 1 is in close contact with the pet's waist, and then engages the engaging portion 70 of the second end 8 with the target portion 71. By engaging the engaging portion 70 with the target portion 71 in this manner, the absorbent article for pets 1 can be attached to the pet at an appropriate position.

[0077] Since the shrinkage rate of the first portion 2A is higher than that of the second portion 2B, it becomes easy to place the second portion 2B against the pet's body and align the pet absorbent article 1. In addition, since the first portion 2A shrinks and the pet absorbent article 1 comes into close contact with the pet's body, the fit of the pet absorbent article 1 is improved.

[0078] As described above, in the pet absorbent article 1, the pair of outer elastic members 61, 62 contract in the longitudinal direction Y, causing the pair of leakproof sheets 40 to stand up relative to the main body 2 and to come into close contact with the pet's body. In addition, the multiple inner elastic members 63 provided between the first standing line 45a and the fourth standing line 55a contract to follow changes in the pet's body shape and posture, improving the fit of the pet absorbent article 1. As a result, the formation of gaps between the pet absorbent article 1 and the pet's body is suppressed, and urine leakage can be effectively suppressed.

[0079] Next, an absorbent article for pets according to another embodiment will be described. Fig. 6 is a plan view of an absorbent article for pets 1A according to another embodiment, seen from the skin side Z1. Fig. 7 is a cross-sectional view showing a schematic diagram of the absorbent article for pets 1A. The absorbent article for pets 1A differs from the absorbent article for pets 1 shown in Fig. 1 in that the main body 2 includes a plurality of inner elastic members 63A instead of the plurality of inner elastic members 63. In the following description, differences from the absorbent article for pets 1 will be mainly described, and overlapping descriptions will be omitted.

[0080] The main body 2 of the pet absorbent article 1A includes a plurality of inner elastic members 63A that are stretchable in the longitudinal direction Y. The inner elastic members 63A are provided inside the pair of outer elastic members 61, 62 in the short direction X, and extend over the entire area of ​​the main body 2 in the longitudinal direction Y. This allows the main body 2 to stretch over the entire area in the longitudinal direction Y so as to follow changes in the pet's body shape and posture, effectively improving the fit of the pet absorbent article 1A.

[0081] The multiple inner elastic members 63A overlap the entire absorbent body 30 in the longitudinal direction Y when viewed from the thickness direction Z. As a result, even when urine is absorbed by the absorbent body 30, the absorbent body 30 is lifted by the contraction force of the inner elastic members 63A, and sagging of the absorbent body 30 is suppressed. Therefore, the fit of the pet absorbent article 1A can be maintained.

[0082] The multiple inner elastic members 63A are disposed on the non-skin facing side Z2 of the topsheet 15. In particular, as shown in Fig. 7, some of the multiple inner elastic members 63A are disposed between the absorbent body 30 and the backsheet 20. Note that an intermediate sheet made of nonwoven fabric may be disposed between some of the multiple inner elastic members 63A and the absorbent body 30.

[0083] The inner elastic member 63A may overlap the engaging portion 70 as viewed from the thickness direction Z. For example, when the engaging portion 70 is divided into three equal regions in the short-side direction X, the regions are, in order from the front side, a front region 70a, a central region 70b, and a rear region 70c, the inner elastic members 63A overlap at least the central region 70b as viewed from the thickness direction Z. As shown in FIG. 6, the inner elastic members 63A may overlap all of the front region 70a, the central region 70b, and the rear region 70c as viewed from the thickness direction Z. When the target portion 71 is provided as in this embodiment, the inner elastic member 63A may overlap the target portion 71 as viewed from the thickness direction Z. The outer elastic members 61 and 62 are located outside the engaging portion 70 in the short-side direction X.

[0084] As described above, in the pet absorbent article 1A, the main body 2 expands and contracts over the entire area in the longitudinal direction Y so as to follow changes in the pet's body shape and posture, thereby improving the fit of the pet absorbent article 1A. As a result, the formation of gaps between the pet absorbent article 1A and the pet's body is suppressed, and urine leakage can be effectively suppressed.

[0085] Next, a pet absorbent article according to yet another embodiment will be described. Fig. 8 is a plan view of a pet absorbent article 1B according to yet another embodiment, as viewed from the skin side Z1. The pet absorbent article 1B shown in Fig. 8 differs from the pet absorbent article 1 shown in Fig. 1 in that the main body 2 includes a plurality of inner elastic members 63B instead of the plurality of inner elastic members 63. In the following description, differences from the pet absorbent article 1 will be mainly described, and overlapping descriptions will be omitted.

[0086] The main body 2 of the absorbent article for pet 1B includes a plurality of inner elastic members 63B that are stretchable in the longitudinal direction Y. The plurality of inner elastic members 63B are provided in the second portion 2B of the main body 2. More specifically, the plurality of inner elastic members 63B are provided in the second end portion 8. Therefore, a center P5 of the inner elastic members 63B in the longitudinal direction Y is disposed on the second side edge 6 side with respect to a center line P4 of the absorber 30 in the longitudinal direction Y.

[0087] The first portion 2A of the main body 2 includes a non-stretchable region R3 that does not include the inner elastic member 63B, and the second portion 2B of the main body 2 includes a stretchable region R4 that includes the inner elastic member 63B. In the embodiment shown in FIG. 8, the first end 7 includes the non-stretchable region R3, and the second end 8 includes the stretchable region R4. Therefore, the contraction rate of the second portion 2B is higher than that of the first portion 2A. That is, the contraction rate of the second end 8 is higher than that of the first end 7. Note that some of the inner elastic members 63B may extend from the second side edge 6 to the middle of the first portion 2A, and only a portion of the first portion 2A may constitute the non-stretchable region R3.

[0088] In the pet absorbent article 1B, the engagement portion 70 is provided on the outer surface of the back sheet 20. The engagement portion 70 is capable of directly engaging with the top sheet 15 from the skin-facing side Z1. When a target portion is provided on the top sheet 15, the engagement portion 70 may be capable of engaging with the top sheet 15 via the target portion. In the pet absorbent article 1B, the engagement portion 70 engages with the surface of the top sheet 15.

[0089] The pet absorbent article 1B configured as above can be put on a pet as follows. First, the user presses the first end 7 of the pet absorbent article 1B against the pet's back and holds the vicinity of the first end 7 with one hand. Next, the user holds the second end 8 of the pet absorbent article 1B with the other hand and wraps the pet absorbent article 1B around the pet's abdomen. Next, the user pulls the second end 8 upward so that the pet absorbent article 1B fits closely around the pet's waist, and then engages the engagement portion 70 at the first end 7 with the surface of the top sheet 15.

[0090] At this time, since the contraction rate of the second portion 2B is higher than that of the first portion 2A, the first portion 2A can be placed against the pet's body to easily align the pet absorbent article 1B. In addition, the second portion 2B contracts to bring the pet absorbent article 1B into close contact with the pet's body, improving the fit of the pet absorbent article 1B.

[0091] Next, a pet absorbent article according to yet another embodiment will be described. Fig. 9 is a plan view of a pet absorbent article 1C according to yet another embodiment, as viewed from the skin side Z1. The pet absorbent article 1C shown in Fig. 9 differs from the pet absorbent article 1 shown in Fig. 1 in that the main body 2 includes a pair of outer elastic members 61C, 62C instead of the pair of outer elastic members 61, 62.

[0092] As shown in FIG. 9, the outer elastic members 61C and 62C are provided on the outer sides of the pair of first and fourth standing lines 45a and 55a in the short-side direction X. The outer elastic member 61C extends along the front edge 3, and the outer elastic member 62C extends along the rear edge 4. Each of the outer elastic members 61C and 62C is formed discontinuously in the longitudinal direction Y. More specifically, the outer elastic member 61C includes a first portion 611C and a second portion 612C spaced apart from each other in the longitudinal direction Y. The first portion 611C is disposed on one side of the longitudinal direction Y with respect to the center line P4 of the absorber 30, and the second portion 612C is disposed on the other side of the longitudinal direction Y with respect to the center line P4 of the absorber 30. A non-stretchable region where the outer elastic member 61C is not disposed is formed between the first portion 611C and the second portion 612C. This non-elastic region is formed so as to straddle the center line P1 in the longitudinal direction Y.

[0093] The outer elastic member 62C includes a first portion 621C and a second portion 622C spaced apart from each other in the longitudinal direction Y. The first portion 621C is disposed on one side in the longitudinal direction Y with respect to a center line P4 of the absorber 30, and the second portion 622C is disposed on the other side in the longitudinal direction Y with respect to the center line P4 of the absorber 30. A non-stretchable region where the outer elastic member 61C is not disposed is formed between the first portion 621C and the second portion 622C. This non-stretchable region is formed so as to straddle the center line P1 in the longitudinal direction Y.

[0094] Some types of pets have little hair around their stomachs. In such cases, the pet may feel pain when the outer elastic member 61C presses against the pet's stomach. In response to this, a non-stretchable area where the outer elastic member 61C is not disposed is formed between the first portion 611C and the second portion 612C of the outer elastic member 61C, so that the outer elastic member 61C can be prevented from pressing against the pet's stomach.

[0095] Furthermore, if the outer elastic member 62C presses against the pet's genitals, the genitals may be rubbed and darkened, or the pet may feel pain. In response to this, a non-stretchable region where the outer elastic member 62C is not disposed is formed between the first portion 621C and the second portion 622C of the outer elastic member 62C, so that the outer elastic member 62C can be prevented from pressing against the pet's genitals.

[0096] Next, a packaging body 90 for housing a plurality of pet absorbent articles 1 will be described. Fig. 10 is a cross-sectional view showing a packaging body 90 according to one embodiment. The packaging body 90 includes a packaging sheet 91 for packaging a plurality of pet absorbent articles 1. In Fig. 10, the pet absorbent articles 1 are packaged in the packaging sheet 91 with the main body 2 folded in three in the longitudinal direction Y. The pet absorbent articles 1 may be packaged in the packaging sheet 91 with the main body 2 folded in four in the longitudinal direction Y. The packaging sheet 91 is made of a synthetic resin such as polyethylene, polypropylene, or polyethylene terephthalate.

[0097] Next, a procedure for folding the absorbent article for pets 1 will be described with reference to Figs. 11 and 12. First, as shown in Fig. 11, the front flap portion 11 is folded inward along a fold line L3 extending in the longitudinal direction Y so that the inner edge 44a in the lateral direction X of the front leakproof sheet 41 is exposed. As shown in Fig. 2, the fold line L3 is located closer to the front edge 3 than the middle line between the front edge 3 and the inner edge 44a in the lateral direction X. That is, the distance between the front edge 3 and the fold line L3 in the lateral direction X is shorter than the distance between the inner edge 44a in the lateral direction X and the fold line L3. By folding the front flap portion 11 along such a fold line L3, the inner edge 44a of the side sheet 42 is exposed. On the other hand, the rear flap portion 12 is not folded inward in the lateral direction X.

[0098] 12, the main body portion 2 is folded in three in the longitudinal direction Y. More specifically, after the second end portion 8 is folded inward in the longitudinal direction Y, the first end portion 7 is folded inward in the longitudinal direction Y so as to overlap the second end portion 8. At this time, the engagement portion 70 is engaged with the target portion 71. The pet absorbent article 1 folded as described above is contained in a packaging body 90.

[0099] As described above, in the package 90, when the folded pet absorbent article 1 is unfolded in the longitudinal direction Y, the inner edge 44a in the lateral direction X of the front leakproof sheet 41 is exposed. This ensures that the front leakproof sheet 41 comes into contact with the pet's body even when the pet absorbent article 1 is worn after being unfolded in three, and as a result, the front leakproof sheet 41 can effectively prevent urine leakage. Therefore, even when the pet absorbent article 1 is worn without unfolding the front flap portion 11, the front leakproof sheet 41 comes into contact with the pet's body, and therefore the front leakproof sheet 41 can prevent urine leakage.

[0100] Furthermore, in the packaging body 90, the rear flap portion 12 is not folded inward in the short direction X, so that the user can easily recognize the front and rear orientations of the absorbent article for pet 1 when removing the absorbent article for pet 1 from the packaging body 90. For example, since it is possible to easily recognize where the front leakproof sheet 41 is located in the absorbent article for pet 1, the absorbent article for pet 1 can be easily put on so that the front leakproof sheet 41 is positioned on the head side of the pet.

[0101] Although various embodiments of the absorbent article for pets have been described above, the present invention is not limited to the above-mentioned embodiments, 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 are for illustrative purposes only and do not limit the scope of the present invention.

[0102] For example, in each of the above-mentioned pet absorbent articles 1, 1A, 1B, and 1C, the front leakproof sheet 41 may not have the first elastic member 43, and the rear leakproof sheet 51 may not have the first elastic member 53. Moreover, each of the pet absorbent articles 1, 1A, 1B, and 1C may not have the pair of leakproof sheets 40.

[0103] In each of the above-mentioned pet absorbent articles 1, 1A, 1B, and 1C, the top sheet 15 in the first portion 2A and the top sheet 15 in the second portion 2B may be engaged with each other. Also, in each of the pet absorbent articles 1, 1A, 1B, and 1C, the back sheet 20 in the first portion 2A and the back sheet 20 in the second portion 2B may be engaged with each other. The above-mentioned various embodiments can be combined to the extent that there is no contradiction. [Explanation of symbols]
