[0009] [Summary of Embodiments of the Present Disclosure] The summary of the embodiments of the present disclosure will be described with reference to the clauses listed below. Note that the present disclosure includes any combination of the following clauses.

[0010] (Clause 1) An absorbent article for pets according to one aspect is worn by being wound around the pet's torso. This absorbent article for pets has a horizontally long shape having a longitudinal direction and a lateral direction, and includes a surface sheet disposed on the skin side, a back sheet disposed on the non-skin side, and an absorber disposed between the surface sheet and the back sheet. A main body portion, a first portion disposed on one side in the longitudinal direction with respect to the center line of the main body portion in the longitudinal direction, and a second portion disposed on the other side in the longitudinal direction with respect to the center line of the main body portion in the longitudinal direction. The main body portion, an engaging portion provided in the first portion of the main body portion for engaging the first portion and the second portion, and a pair of leak-proof sheets that can stand up with respect to the surface 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 portion is provided inside the pair of standing lines in the lateral direction and further includes one or more inner elastic members that impart elasticity to the main body portion.

[0011] In the above aspect, when a pair of outer elastic members contract in the longitudinal direction, a pair of leak-proof sheets stand up with respect to the surface sheet and adhere to the body of the pet. In addition, since one or more inner elastic members provided inside a pair of standing lines in the short-side direction contract so as to follow changes in the body shape and posture of the pet, the fit of the absorbent article for pets can be improved. As a result, it is possible to suppress the formation of a gap between the absorbent article for pets and the body of the pet, and effectively suppress urine leakage.

[0012] (Article 2) In the absorbent article for pets according to Article 1, one or more inner elastic members may expand and contract in the longitudinal direction. In this case, since one or more inner elastic members contract so as to follow changes in the body shape and posture of the pet in the longitudinal direction, the fit of the absorbent article for pets can be improved. As a result, urine leakage can be effectively suppressed.

[0013] (Article 3) In the absorbent article for pets according to Article 2, one or more inner elastic members may extend over the entire area of the main body portion in the longitudinal direction. In this case, since the main body portion expands and contracts over the entire area in the longitudinal direction, the absorbent article for pets can be fitted to the body of the pet over the entire area around the pet's torso when the absorbent article for pets is worn. Thereby, displacement of the absorbent article for pets can be suppressed, and urine leakage can be more effectively suppressed.

[0014] (Article 4) In the absorbent article for pets according to any one of Articles 1 to 3, the engaging portion may be provided on the surface of the surface sheet and engageable with the back sheet. In this case, the absorbent article for pets can be easily attached to the pet using the engaging portion.

[0015] (Article 5) In the absorbent article for pets according to Item 4, the first part includes an elastic region including one or more inner elastic members, the second part includes a non-elastic region not including one or more inner elastic members, and the shrinkage rate of the first part may be higher than the shrinkage rate of the second part. In this case, the second part with a relatively low shrinkage rate can be applied to the body of the pet to align the absorbent article for pets. Further, when the second part is engaged with the first part, the first part with a relatively high shrinkage rate shrinks, thereby reducing the looseness during wearing of the absorbent article for pets. Therefore, the fit of the absorbent article for pets can be improved.

[0016] (Item 6) In the absorbent article for pets according to any one of Items 1 to 5, the center of one or more inner elastic members in the longitudinal direction may be arranged on one side in the longitudinal direction with respect to the center line of the absorber in the longitudinal direction. In this case, the region on one side of the main body part is more likely to expand and contract than the region on the other side of the main body part with respect to the center line of the absorber. Thereby, it becomes easy to align the absorbent article for pets by applying the region on the other side of the main body part to the body of the pet. Further, when the first part is engaged with the second part, the region on one side of the main body part shrinks, thereby reducing the looseness during wearing of the absorbent article for pets.

[0017] (Item 7) In the absorbent article for pets according to any one of Items 1 to 3, the engaging part may be provided on the outer surface of the back sheet and be engageable with the front sheet. In this case, the absorbent article for pets can be easily worn on the pet using the engaging part.

[0018] (Item 8) In the absorbent article for pets according to Item 7, the first part includes a non-stretchable region that does not include one or more inner elastic members, the second part includes a stretchable region that includes one or more inner elastic members, and the shrinkage rate of the second part may be higher than the shrinkage rate of the first part. In this case, the first part with a relatively low shrinkage rate can be applied to the body of the pet to align the absorbent article for pets. Also, when the second part is engaged with the first part, the relatively high shrinkage rate of the second part causes it to shrink, thereby reducing the looseness during the wearing of the absorbent article for pets. Therefore, the fit of the absorbent article for pets can be improved.

[0019] (Item 9) In the absorbent article for pets according to Item 7 or 8, the center of one or more inner elastic members in the longitudinal direction may be arranged on the other side in the longitudinal direction with respect to the center line of the absorber 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 absorber has higher stretchability than the region on one side of the main body part. This makes it easy to align the absorbent article for pets by applying the region on one side of the main body part to the body of the pet. Also, since the region on the other side of the main body part shrinks when the first part and the second part are engaged, the looseness during the wearing of the absorbent article for pets is reduced.

[0020] (Item 10) In the absorbent article for pets according to any one of Items 1 to 9, one or more inner elastic members may overlap the engaging part when viewed from the thickness direction of the main body part. In this case, the engaging part is pulled by the shrinking force of the inner elastic member, so that the first part and the second part are firmly engaged. This prevents the absorbent article for pets from coming off unintentionally.

[0021] (Item 11) In the absorbent article for pets according to any one of Items 1 to 9, one or more inner elastic members may not overlap the engaging portion when viewed in the thickness direction of the main body portion. By arranging the one or more elastic members so as not to overlap the engaging portion, it is possible to prevent the engaging portion from being deformed into a wavy shape by the contracting force of the inner elastic member. Therefore, it is possible to prevent the engagement between the first portion and the second portion from being unintentionally released.

[0022] (Item 12) In the absorbent article for pets according to any one of Items 1 to 11, one or more inner elastic members may not overlap the absorber when viewed in the thickness direction of the main body portion. In this case, it is possible to prevent the absorber from being deformed due to the expansion and contraction of the inner elastic member.

[0023] (Item 13) In the absorbent article for pets according to any one of Items 1 to 11, one or more inner elastic members may overlap the absorber when viewed in the thickness direction of the main body portion. In this case, even when urine is absorbed by the absorber, the absorber is lifted by the contracting force of the inner elastic member, and the sagging of the absorber is suppressed. Therefore, the fitness of the absorbent article for pets can be maintained.

[0024] (Item 14) In the absorbent article for pets according to any one of Items 1 to 13, each of the pair of outer elastic members may continuously extend in the longitudinal direction. In this case, the absorbent article for pets can be fitted to the body of the pet by the contracting force of the pair of outer elastic members.

[0025] (Item 15) In the absorbent article for pets according to any one of Items 1 to 13, each of the pair of outer elastic members may be formed discontinuously. In this case, since the outer elastic member partially contracts in the longitudinal direction, it is possible to reduce the pressure on the body of the pet by the pair of outer elastic members.

[0026] (Item 16) In the absorbent article for pets according to any one of Items 1 to 15, the pair of leak-proof sheets includes a front leak-proof sheet that can stand up along the first standing line among the pair of standing lines, and a rear leak-proof sheet that can stand up along the second standing line among the pair of standing lines. The maximum standing height of the front leak-proof sheet based on the main body portion may be higher than the maximum standing height of the rear leak-proof sheet based on the main body portion. In this case, when the absorbent article for pets is worn so that the front leak-proof sheet is arranged on the head side of the pet, the urine of the pet can be blocked by the front leak-proof sheet, so urine leakage can be effectively suppressed.

[0027] (Item 17) In the absorbent article for pets according to any one of Items 1 to 16, the main body portion includes a plurality of inner elastic members, and the plurality of inner elastic members may be arranged along the short side direction. In this case, since each inner elastic member contracts so as to follow changes in the body shape and posture of the pet, the fit of the absorbent article for pets can be improved.

[0028] (Item 18) The absorbent article for pets according to another aspect is worn by being wound around the pet's torso. This absorbent article for pets has a horizontally long shape having a longitudinal direction and a short side direction, and includes a surface sheet arranged on the skin side, a back sheet arranged on the non-skin side, and an absorber arranged between the surface sheet and the back sheet. The main body portion has a first portion arranged on one side in the longitudinal direction with respect to the center line of the main body portion in the longitudinal direction, and a second portion arranged on the other side in the longitudinal direction with respect to the center line of the main body portion in the longitudinal direction. The main body portion is provided with an engaging portion provided in the first portion of the main body portion for engaging the first portion and the second portion, and a pair of outer elastic members provided outside the absorber in the short side direction and stretchable in the longitudinal direction. The main body portion is arranged on the non-skin side with respect to the surface sheet, and further includes one or more inner elastic members that impart elasticity to the main body portion. The one or more inner elastic members are provided inside the pair of outer elastic members in the short side direction and overlap the engaging portion when viewed from the thickness direction of the main body portion.

[0029] In the absorbent article for pets according to the above aspect, since one or a plurality of inner elastic members contract so as to follow changes in the body shape and posture of the pet, the fit of the absorbent article for pets can be improved. As a result, the formation of a gap between the absorbent article for pets and the body of the pet can be suppressed, and urine leakage can be effectively suppressed.

[0030] (Article 19) In the absorbent article for pets according to Article 18, when each region obtained by trisecting the engaging portion in the short direction is defined as a front region, a central region, and a rear region in order from one side in the short direction, one or a plurality of inner elastic members may overlap the central region when viewed from 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 package according to one aspect houses the absorbent article for pets according to any one of Articles 1 to 17. The main body portion of this absorbent article for pets includes a front flap portion and a rear flap portion disposed outside the absorber in the short direction, and the pair of leak-proof sheets includes a front leak-proof sheet that can stand up along the first standing line among the pair of standing lines and a rear leak-proof sheet that can stand up along the second standing line among the pair of standing lines. The absorbent article for pets is housed in the package in a state where the main body portion is folded into three or four folds in the longitudinal direction after the front flap portion is folded inward along a folding line extending in the longitudinal direction so that the inner edge in the short direction of the front leak-proof sheet is exposed.

[0032] In the above aspect, when the absorbent article for pets folded into three or four folds is unfolded in the longitudinal direction, the inner edge in the short direction of the front leak-proof sheet is exposed. Therefore, even when the absorbent article for pets is worn without unfolding the front flap portion, the front leak-proof sheet contacts the body of the pet. Thus, urine leakage can be suppressed by the front leak-proof sheet.

[0033] (Article 21) In the package according to Item 20, the rear flap portion may not be folded inward in the short side direction. When the front flap portion is folded and the rear flap portion is not folded, when the user takes out the pet absorbent article from the package, the front and rear orientations of the pet absorbent article can be easily recognized. This makes it easier to attach the pet absorbent article to the pet in the correct orientation.

[0034] [Examples of Embodiments of the Present Disclosure] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the description of the drawings, the same reference numerals are assigned to the same elements, and redundant descriptions are omitted. The drawings may be drawn with some parts simplified or exaggerated for ease of understanding, and the dimensional ratios are not limited to those shown in the drawings.

[0035] Hereinafter, a pet absorbent article according to an embodiment will be described. FIG. 1 is a perspective view schematically showing a pet absorbent article 1 according to an embodiment. FIG. 2 is a plan view of the pet absorbent article 1 as viewed from the skin side Z1. FIG. 3 is a cross-sectional view of the pet absorbent article 1 taken along line A-A in FIG. 1. FIG. 4 is a cross-sectional view of the pet absorbent article 1 taken along line B-B in FIG. 1. FIG. 5 is a cross-sectional view of the pet absorbent article 1 taken along line C-C in FIG. 1. The pet absorbent article 1 shown in FIGS. 1 to 5 is a disposable diaper for pets that absorbs the urine of pets.

[0036] Figure 1 shows the absorbent article 1 for pets in a natural state. The natural state means a state where no external force is applied to the absorbent article 1 for pets. Figure 2 shows the absorbent article 1 for pets in a deployed state. The deployed state means a state where the absorbent article 1 for pets is extended until no wrinkles are formed. The skin side Z1 is the side that faces the pet's skin surface when the absorbent article 1 for pets is in a worn state, and the non-skin side Z2 is the side that faces the side opposite to the pet's skin surface when the absorbent article 1 for pets is in a worn state. In the following description, the person who wears the absorbent article 1 for pets is referred to as the "user". Typically, the user is the owner of the pet. In the following description, unless otherwise specified, the positional relationship in the deployed state will be described.

[0037] In this specification, pets widely include vertebrates and invertebrates, and typically include pet animals such as dogs, cats, rabbits, and hamsters. The absorbent article 1 for pets is particularly preferably used for male pets whose urethral orifice is located in front of the base of the hind legs. As shown in Figure 2, the absorbent article 1 for pets extends in the transverse direction X arranged along the front-rear direction (the direction connecting the head and the buttocks) of the pet, and the longitudinal direction Y arranged along the circumferential direction of the pet's body. The transverse direction X and the longitudinal direction Y are perpendicular to each other. The thickness direction Z is a direction perpendicular to the transverse direction X and the longitudinal direction Y, and includes the skin side Z1 that faces the pet's skin surface in the worn state, and the non-skin side Z2 that faces the side opposite to the pet's skin surface in the worn state. The absorbent article 1 for pets is wound around the pet's body and worn.

[0038] The absorbent article 1 for pets includes a main body portion 2. The main body portion 2 has a substantially rectangular (landscape-shaped) planar shape having a short side direction X and a long side direction Y. The four corner portions of the main body portion 2 are cut so that the width of the main body portion 2 in the short side direction X becomes narrower. Note that the four corner portions of the main body portion 2 may not be cut. The main body portion 2 has a front edge 3 disposed on one end side in the short side direction X and a rear edge 4 disposed on the other end side in the short side direction X. When the absorbent article 1 for pets is worn on a pet, the front edge 3 is disposed on the front leg side of the pet, and the rear edge 4 is disposed on the rear leg side of the pet. In the following description, the direction from the rear edge 4 toward the front edge 3 may be referred to as the front side, and the direction from the front edge 3 toward the rear edge 4 may be referred to as the rear side. Further, the main body portion 2 has a first side edge 5 disposed on one end side in the long side direction Y and a second side edge 6 disposed on the other end side in the long side direction Y. Further, the main body portion 2 has a first portion 2A disposed on one side in the long side direction Y with respect to the center line P1 of the main body portion 2 in the long side direction Y, and a second portion 2B disposed on the other side in the long side direction Y with respect to the center line P1 of the main body portion 2 in the long side direction Y.

[0039] As shown in FIGS. 1 to 5, the main body portion 2 includes a top sheet 15, a back sheet 20, an absorber 30, and a pair of leak-proof sheets 40. The top sheet 15 constitutes the surface of the main body portion 2 that contacts the pet and is disposed on the skin surface side Z1. The top sheet 15 has, for example, liquid permeability that allows the urine of the pet to permeate toward the absorber 30 side. The top sheet 15 is located substantially at the center in the short side direction X. Examples of the nonwoven fabric constituting the top sheet 15 include an air-through nonwoven fabric, a spunbond nonwoven fabric, or a point-bond nonwoven fabric. The top sheet 15 is joined to the back sheet 20 and the absorber 30 with, for example, a hot melt adhesive.

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

[0041] The absorber 30 is disposed between the top sheet 15 and the back sheet 20. The absorber 30 is positioned substantially at the center of the main body 2 and absorbs the urine of the pet. The absorber 30 has a substantially rectangular shape extending in the longitudinal direction Y.

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

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

[0044] In one embodiment, the absorber 30 includes an absorbent core containing pulp having water absorbency and a superabsorbent polymer (SAP), and a core wrap covering the surface of the absorbent core. As the pulp of the absorbent core, for example, chemical pulp, cellulose fibers such as cellulose fibers, rayon, and acetate are used. As the superabsorbent polymer, for example, starch-based, acrylic acid-based, or amino acid-based particulate or fibrous polymers are used. Note that the absorber 30 may be a SAP sheet mainly composed of SAP without containing pulp.

[0045] A pair of leak-proof sheets 40 are provided on the surface sheet 15 and are spaced apart from each other in the short direction X. The pair of leak-proof sheets 40 are arranged to cover both side portions of the surface sheet 15 in the short direction X from the skin side Z1 and extend in the longitudinal direction Y over the entire length of the main body portion 2 in the longitudinal direction Y. The pair of leak-proof sheets 40 are partially joined to the surface sheet 15 or the back sheet 20 outside the absorber 30 in the short direction X. The pair of leak-proof sheets 40 stand up with respect to the surface sheet 15 to suppress leakage of urine excreted by the pet to the absorber 30 in the short direction X. The pair of leak-proof sheets 40 includes 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 turning back the back nonwoven fabric 22 to the surface sheet 15 side outside the main body portion 2 in the short direction X. In this case, a part of the back nonwoven fabric 22 turned back to the surface sheet 15 side constitutes the pair of leak-proof sheets 40, and the other part of the back nonwoven fabric 22 constitutes the back sheet 20 of the main body portion 2.

[0046] In one embodiment, the front leak-proof sheet 41 includes a side sheet 42 partially fixed to the front surface sheet 15 or the back surface sheet 20, and a first elastic member 43 joined to the side sheet 42. The rear leak-proof sheet 51 includes a side sheet 52 partially fixed to the front surface sheet 15 or the back surface 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 water-repellent or hydrophobic non-woven fabric. For example, the side sheets 42, 52 are made of a spunlace non-woven fabric, a spunbond non-woven fabric, a thermal bond non-woven fabric, a meltblown non-woven fabric, an SMS non-woven fabric, a needle-punched non-woven fabric, an air-through non-woven fabric, or the like.

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

[0048] As shown in FIGS. 2 to 5, the side sheet 42 includes a fixed portion 45 joined to the front surface sheet 15 or the back surface sheet 20, and a standing portion 46 not joined to the front surface sheet 15. At the boundary between the fixed portion 45 and the standing portion 46, a first standing line 45a, a second standing line 45b, and a third standing line 45c are formed.

[0049] The first standing line 45a is disposed between the center line P2 in the short direction X of the main body 2 and the front edge 3 and extends in the longitudinal direction Y. For example, the first standing line 45a is disposed between the edge of the absorber 30 on the front side and the front edge 3. The first standing line 45a is the boundary line between the fixing portion 45 and the standing portion 46 in the short direction X and serves as the standing fulcrum for the standing portion 46 in the short direction X. Note that 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 in the longitudinal direction Y of the main body 2 and the first side edge 5 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 on the first side edge 5 side of the absorber 30 in the longitudinal direction Y. The second standing line 45b is the boundary line between the fixing portion 45 and the standing portion 46 in the longitudinal direction Y and serves as the standing fulcrum for the standing portion 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 on the first side edge 5 side of the absorber 30 in the longitudinal direction Y.

[0051] The third standing line 45c is disposed between the center line P1 in the longitudinal direction Y of the main body 2 and the second side edge 6 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 the boundary line between the fixing portion 45 and the standing portion 46 in the longitudinal direction Y and serves as the standing fulcrum for 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, among the side sheets 42, the first region 42A 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 portion 2 by a hot melt adhesive in a state of being fallen inward in the short side direction X. Similarly, among the side sheets 42, the second region 42B 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 portion 2 by a hot melt adhesive in a state of being fallen inward in the short side direction X. Therefore, as shown in FIGS. 3 and 5, the first region 42A and the second region 42B of the side sheet 42 are fixed to the main body portion 2 and are non-standing regions that do not stand up.

[0053] On the other hand, the standing portion 46 is disposed between the first region 42A and the second region 42B, and is a standing region not connected to the main body portion 2. The standing portion 46 is disposed inside the first standing line 45a in the short side direction X, and can stand up 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 falls inward in the short side direction X when in the unfolded state.

[0054] The inner portion of the standing portion 46 in the short side direction X is folded back, and a first elastic member 43 is disposed between the folded standing portions 46. Therefore, as shown in FIG. 2, the first elastic member 43 of the front leak-proof sheet 41 is disposed along the inner edge 44a of the standing portion 46. The first elastic member 43 is joined to the side sheet 42 in a state of being extended in the longitudinal direction Y. The first elastic member 43 is made of a stretchable material such as rubber or spandex that can contract in the length direction, for example.

[0055] As shown in FIG. 4, the standing portion 46 of the side sheet 42 stands up along the first standing line 45a outside the short side direction X of the absorber 30 due to the first elastic member 43 contracting in the longitudinal direction Y in the natural state. By the standing portion 46 of the front leak-proof sheet 41 standing up, it is possible to prevent urine of the pet from leaking forward along the surface of the surface sheet 15.

[0056] The side sheet 52 includes a fixing portion 55 joined to the front sheet 15 or the back sheet 20, and an upright portion 56 not joined to the front sheet 15. At the boundary between the fixing 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 upright line 55a is disposed between the center line P2 in the lateral direction X of the main body portion 2 and the rear edge 4, and extends in the longitudinal direction Y. For example, the fourth upright line 55a is disposed between the edge of the absorber 30 on the rear side and the rear edge 4. The fourth upright line 55a is the boundary line between the fixing portion 55 and the upright portion 56 in the lateral direction X, and serves as the upright fulcrum for the upright portion 56 in the lateral direction X. Note that the fourth upright line 55a may partially overlap the absorber 30 when viewed from the thickness direction Z.

[0058] The fifth upright line 55b is disposed between the center line P1 in the longitudinal direction Y of the main body portion 2 and the first side edge 5, and extends in the lateral direction X. For example, the fifth upright 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 upright line 55b is the boundary line between the fixing portion 55 and the upright portion 56 in the longitudinal direction Y, and serves as the upright fulcrum for the upright portion 56 in the longitudinal direction Y. Note that the fifth upright 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 upright line 55c is disposed between the center line P1 in the longitudinal direction Y of the main body portion 2 and the second side edge 6, and extends in the lateral direction X. For example, the sixth upright 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 upright line 55c is the boundary line between the fixing portion 55 and the upright portion 56 in the longitudinal direction Y, and serves as the upright fulcrum for the upright portion 56 in the longitudinal direction Y. Note that the sixth upright 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, among the side sheets 52, the first region 52A on the side of the first side edge 5 with respect to the fifth standing line 55b is a part of the fixing portion 55, and is joined to the main body portion 2 by a hot melt adhesive in a state of being folded back to the outside in the lateral direction X. More specifically, the first region 52A is folded back to the outside in the lateral direction X along the extension line of the fourth standing line 55a, the lower layer of the folded first region 52A is joined to the surface sheet 15 or the back sheet 20, and the upper layer of the folded first region 52A is joined to the lower layer. Similarly, among the side sheets 52, the second region 52B on the side of the second side edge 6 with respect to the sixth standing line 55c is a part of the fixing portion 55, and is joined to the main body portion 2 by a hot melt adhesive in a state of being folded back to the outside in the lateral direction X. More specifically, the second region 52B is folded back to the outside in the lateral direction X along the extension line of the fourth standing line 55a, the lower layer of the folded second region 52B is joined to the surface sheet 15 or the back sheet 20, and the upper layer of the folded second region 52B is joined to the lower layer. Therefore, as shown in FIGS. 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] On the other hand, the standing portion 56 is disposed between the first region 52A and the second region 52B, and is a standing region not connected to the main body portion 2. The standing portion 56 is disposed inside the fourth standing line 55a in the lateral direction X, and can stand up 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 portion 2 in a state of being folded back to the outside in the lateral direction X, the standing portion 56 falls to the outside in the lateral direction X when in the unfolded state. When the standing portion 56 falls to the outside in the lateral direction X when in the unfolded state, rubbing of the first elastic member 53 of the rear leak-proof sheet 51 against the pet's genital organ is prevented when the absorbent article 1 for pets is worn. Each of the first region 52A and the second region 52B may be joined to the main body portion 2 without being folded back to the outside in the lateral direction X. In this case, the standing portion 56 falls to the inside in the lateral direction X when in the unfolded state.

[0062] The inner part of the standing portion 56 in the short-side direction X is folded back, and a first elastic member 53 is disposed between the folded-back standing portions 56. Therefore, as shown in FIG. 2, the first elastic member 53 of the rear leak-proof sheet 51 is disposed along the inner edge 54a of the standing portion 56. The first elastic member 53 is joined to the side sheet 52 in a state of being extended in the longitudinal direction Y. The first elastic member 53 is made of a stretchable material such as rubber or spandex that can contract in the length direction, for example.

[0063] As shown in FIG. 4, the standing portion 56 of the side sheet 52 stands up along the fourth standing line 55a outside the absorber 30 in the short-side direction X due to the contraction of the first elastic member 53 in the longitudinal direction Y when in the natural state. When the standing portion 56 of the rear leak-proof sheet 51 stands up, it is possible to prevent the urine of the pet from leaking to the rear along the surface of the surface sheet 15.

[0064] As shown in FIG. 4, the maximum standing height H1 of the front leak-proof sheet 41 with respect to the main body portion 2 may be higher than the maximum standing height H2 of the rear leak-proof sheet 51 with respect to the main body portion 2. The maximum standing height H1 corresponds to the height of the top of the front leak-proof sheet 41 with respect to the main body portion 2 when the front leak-proof sheet 41 stands upright perpendicular to the main body portion 2. In other words, the maximum standing height H1 can also be said to be the length along the surface of the front leak-proof sheet 41 from the first standing line 45a to the top of the standing portion 46 in a cross-section along the short side direction X. Similarly, the maximum standing height H2 corresponds to the height of the top of the rear leak-proof sheet 51 with respect to the main body portion 2 when the rear leak-proof sheet 51 stands upright perpendicular to the main body portion 2. In other words, the maximum standing height H2 can also be said to be the length along the surface of the rear leak-proof sheet 51 from the fourth standing line 55a to the top of the standing portion 56 in a cross-section along the short side direction X. By making the maximum standing height H1 higher than the maximum standing height H2, when the absorbent article 1 for pets is worn so that the front leak-proof sheet 41 is disposed on the head side of the pet, urine vigorously discharged from the pet can be blocked by the front leak-proof sheet 41, so that urine leakage can be effectively suppressed. Note that the maximum standing height H2 of the rear leak-proof sheet 51 may be higher than the maximum standing height H1 of the front leak-proof sheet 41. In this case, urine flowing to the rear can be blocked by the rear leak-proof sheet 51, so that urine leakage can be effectively suppressed.

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

[0066] The outer elastic members 61 are provided outside the first standing line 45a in the lateral direction X and extend along the front edge 3. The outer elastic members 62 are provided outside the fourth standing line 55a in the lateral direction X and extend along the rear edge 4. Each of the outer elastic members 61, 62 continuously extends in the longitudinal direction Y between the first end portion 7 and the second end portion 8. Note that the main body portion 2 may include a plurality of outer elastic members 61 and a plurality of outer elastic members 62. Also, 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 a pair of leak-proof sheets 40 and the back sheet 20. The outer elastic members 61, 62 are joined to the leak-proof sheets 40 and the back sheet 20 by a hot melt adhesive in a state of being stretched in the longitudinal direction Y. That is, the outer elastic members 61, 62 are disposed on the non-skin surface side Z2 with respect to the pair of leak-proof 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 when viewed from the thickness direction Z, or may not overlap both the first end portion 7 and the second end portion 8 when viewed from the thickness direction Z.

[0068] The plurality of inner elastic members 63 are provided inside the first standing line 45a and the fourth standing line 55a in the lateral direction X and impart elasticity to the main body portion 2. In one embodiment, the plurality of inner elastic members 63 are provided at the first end portion 7 of the main body portion 2 and impart elasticity to the first end portion 7. More specifically, the plurality of inner elastic members 63 extend between the absorber 30 and an engagement portion 70 to be described later. Therefore, the center P3 of the inner elastic member 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, since the inner elastic member 63 does not overlap the absorber 30 when viewed from the thickness direction Z, deformation of the absorber 30 due to the contraction force of the inner elastic member 63 can be prevented.

[0069] The plurality of inner elastic members 63 may be arranged at equal intervals along the short-side 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 of 1 or more. The inner elastic members 63 are arranged on the non-skin surface side Z2 with respect to the surface sheet 15. For example, the inner elastic members 63 are arranged between the surface sheet 15 and the back film 21, and are joined to the surface sheet 15 and the back film 21 by a hot melt adhesive in a state of being extended in the longitudinal direction Y. By arranging the inner elastic members 63 on the non-skin surface side Z2 with respect to the surface sheet 15, it is possible to prevent the inner elastic members 63 from directly contacting the body of the pet when the absorbent article 1 for pets is worn, so that the wearing feeling of the absorbent article 1 for pets can be improved.

[0070] In addition, the plurality of 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, since the main body portion 2 can be expanded and contracted so as to follow changes in the body shape and posture of the pet in the short-side direction X (for example, an action of the pet stretching its body, etc.), the fitting property of the absorbent article 1 for pets can be improved.

[0071] In addition, the outer elastic members 61, 62 and the inner elastic members 63 may be joined to the surface 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 members 63 may be joined to the surface sheet 15 or the back sheet 20 by sonic processing.

[0072] The first part 2A of the main body part 2 includes an elastic region R1 containing the inner elastic member 63, and the second part 2B of the main body part 2 includes a non-elastic region R2 not containing the inner elastic member 63. In the embodiment shown in FIG. 2, the first end 7 includes the elastic region R1, and the second end 8 includes the non-elastic region R2. Therefore, the shrinkage rate of the first part 2A is higher than that of the second part 2B. That is, the shrinkage 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 part 2A or the second part 2B in the natural state is L1, and the length in the longitudinal direction Y of the first part 2A or the second part 2B in the unfolded state is L2, the shrinkage rate [%] is represented by (L2 - L1) / L2 × 100. Note that a part of the plurality of inner elastic members 63 may extend to the middle of the second part 2B, and only a part of the second part 2B may constitute the non-elastic region R2. In one embodiment, the inner elastic members 63 may be provided on both the first end 7 and the second end 8. In this case, the first part 2A and the second part 2B may have the same shrinkage rate.

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

[0074] In one embodiment, a target part 71 is provided on the outer surface of the back sheet 20 of the second part 2B. The target part 71 may overlap the absorber 30 and the second end 8 when viewed in the thickness direction Z. When the absorbent article 1 for pets is worn, the engaging part 70 is engaged with the back sheet 20 via the target part 71 provided on the back sheet 20. Note that the engaging part 70 may be directly engaged with the back sheet 20.

[0075] Note that, when viewed from the thickness direction Z, the plurality of inner elastic members 63 may be arranged so as not to overlap the engaging portion 70 and the target portion 71. Thereby, it is possible to prevent the engaging portion 70 and the target portion 71 from being deformed in a wavy manner by the contraction force of the plurality of inner elastic members 63.

[0076] The absorbent article 1 for pets configured as described above can be worn on a pet as follows. First, the user presses the second end portion 8 of the absorbent article 1 for pets against the back of the pet and holds down the vicinity of the second end portion 8 with one hand. Next, the user holds the first end portion 7 of the absorbent article 1 for pets with the other hand and wraps the absorbent article 1 for pets around the abdomen of the pet. At this time, the front leak-proof sheet 41 is disposed in front of the pet relative to the urethral orifice, and the rear leak-proof sheet 51 is disposed behind the pet relative to the urethral orifice, so that the absorbent article 1 for pets is worn. Next, after the user pulls up the first end portion 7 upward so that the absorbent article 1 for pets is in close contact with the pet's body, the user engages the engaging portion 70 of the second end portion 8 with the target portion 71. By engaging the engaging portion 70 and the target portion 71 in this way, the absorbent article 1 for pets can be worn on the pet at an appropriate position.

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

[0078] As described above, in the absorbent article 1 for pets, when the pair of outer elastic members 61 and 62 contract in the longitudinal direction Y, the pair of leak-proof sheets 40 stand up with respect to the main body portion 2 and adhere to the body of the pet. Further, since the plurality of inner elastic members 63 provided between the first standing line 45a and the fourth standing line 55a contract so as to follow changes in the body shape and posture of the pet, the fit of the absorbent article 1 for pets can be improved. As a result, it is possible to suppress the formation of a gap between the absorbent article 1 for pets and the body of the pet, and effectively suppress urine leakage.

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

[0080] The main body portion 2 of the absorbent article 1A for pets includes a plurality of inner elastic members 63A that are stretchable in the longitudinal direction Y. The plurality of inner elastic members 63A are provided inside the pair of outer elastic members 61 and 62 in the short-hand direction X and extend over the entire area of the main body portion 2 in the longitudinal direction Y. Thereby, since the main body portion 2 expands and contracts over the entire area in the longitudinal direction Y so as to follow changes in the body shape and posture of the pet, the fit of the absorbent article 1A for pets is effectively improved.

[0081] The plurality of inner elastic members 63A overlap the entire area of the absorber 30 in the longitudinal direction Y when viewed from the thickness direction Z. Thereby, even when urine is absorbed by the absorber 30, the absorber 30 is lifted by the contraction force of the inner elastic members 63A, and the sagging of the absorber 30 is suppressed. Therefore, the fit of the absorbent article 1A for pets can be maintained.

[0082] The plurality of inner elastic members 63A are arranged on the non-skin surface side Z2 with respect to the surface sheet 15. In particular, as shown in FIG. 7, a part of the plurality of inner elastic members 63A is arranged between the absorber 30 and the back sheet 20. Note that an intermediate sheet made of a non-woven fabric may be arranged between a part of the plurality of inner elastic members 63A and the absorber 30.

[0083] The inner elastic member 63A may overlap the engaging portion 70 when viewed in the thickness direction Z. For example, when each region obtained by trisecting the engaging portion 70 in the short side direction X is defined as a front region 70a, a central region 70b, and a rear region 70c in order from the front side, the plurality of inner elastic members 63A overlap at least the central region 70b when viewed in the thickness direction Z. As shown in FIG. 6, the plurality of inner elastic members 63A may overlap all of the front region 70a, the central region 70b, and the rear region 70c when viewed in the thickness direction Z. When the target portion 71 is provided as in the present embodiment, the inner elastic member 63A may overlap the target portion 71 when viewed in the thickness direction Z. Note that the outer elastic members 61, 62 are located outside the engaging portion 70 in the short side direction X.

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

[0085] Next, a pet absorbent article according to still another embodiment will be described. FIG. 8 is a plan view of a pet absorbent article 1B according to still another embodiment as viewed from the skin surface side Z1. The pet absorbent article 1B shown in FIG. 8 is different 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, the differences from the pet absorbent article 1 will be mainly described, and overlapping descriptions will be omitted.

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

[0087] The first portion 2A of the main body portion 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 portion 2 includes a stretchable region R4 that includes the inner elastic member 63B. In the embodiment shown in FIG. 8, the first end portion 7 includes the non-stretchable region R3, and the second end portion 8 includes the stretchable region R4. Therefore, the shrinkage rate of the second portion 2B is higher than the shrinkage rate of the first portion 2A. That is, the shrinkage rate of the second end portion 8 is higher than the shrinkage rate of the first end portion 7. Note that a part of the plurality of inner elastic members 63B may extend from the second side edge 6 to the middle of the first portion 2A, and only a part of the first portion 2A may constitute the non-stretchable region R3.

[0088] In the absorbent article 1B for pets, the engaging portion 70 is provided on the outer surface of the back sheet 20. The engaging portion 70 can be directly engaged with the surface sheet 15 from the skin side Z1. When a target portion is provided on the surface sheet 15, the engaging portion 70 may be engaged with the surface sheet 15 via the target portion. In the absorbent article 1B for pets, the engaging portion 70 engages with the surface of the surface sheet 15.

[0089] The absorbent article 1B for pets configured as described above can be attached to a pet as follows. First, the user presses the first end portion 7 of the absorbent article 1B for pets against the back of the pet and holds the vicinity of the first end portion 7 with one hand. Next, the user holds the second end portion 8 of the absorbent article 1B for pets with the other hand and wraps the absorbent article 1B for pets around the abdomen of the pet. Next, after the user pulls up the second end portion 8 so that the absorbent article 1B for pets adheres closely to the pet's torso, the user engages the engaging portion 70 with the surface of the surface sheet 15 at the first end portion 7.

[0090] At this time, since the shrinkage rate of the second portion 2B is higher than that of the first portion 2A, the first portion 2A can be applied to the body of the pet to easily align the absorbent article 1B for pets. Further, since the second portion 2B shrinks and the absorbent article 1B for pets adheres closely to the body of the pet, the fit of the absorbent article 1B for pets is improved.

[0091] Next, an absorbent article for pets according to still another embodiment will be described. FIG. 9 is a plan view of an absorbent article 1C for pets according to still another embodiment as viewed from the skin side Z1. The absorbent article 1C for pets shown in FIG. 9 is different from the absorbent article 1 for pets shown in FIG. 1 in that the main body portion 2 includes a pair of outer elastic members 61C and 62C instead of a pair of outer elastic members 61 and 62.

[0092] As shown in FIG. 9, the outer elastic members 61C and 62C are respectively provided outside a pair of first standing lines 45a and fourth standing lines 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 that are spaced apart from each other in the longitudinal direction Y. The first portion 611C is disposed on one side in 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 in the longitudinal direction Y with respect to the center line P4 of the absorber 30. A non-elastic 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] Further, the outer elastic member 62C includes a first portion 621C and a second portion 622C that are spaced apart from each other in the longitudinal direction Y. The first portion 621C 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 622C 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 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] Depending on the type of pet, there may be little hair around the abdomen. In such a case, if the outer elastic member 61C presses on the pet's abdomen, the pet may feel pain. On the other hand, by forming a non-stretchable region where the outer elastic member 61C is not disposed between the first portion 611C and the second portion 612C of the outer elastic member 61C, it is possible to prevent the pet's abdomen from being compressed by the outer elastic member 61C.

[0095] Further, if the outer elastic member 62C presses on the pet's genitalia, the genitalia may be chafed and blackened, or the pet may feel pain. On the other hand, by forming a non-stretchable region where the outer elastic member 62C is not disposed between the first portion 621C and the second portion 622C of the outer elastic member 62C, it is possible to prevent the pet's genitalia from being compressed by the outer elastic member 62C.

[0096] Next, a package 90 for accommodating a plurality of absorbent articles 1 for pets will be described. FIG. 10 is a cross-sectional view showing a package 90 according to an embodiment. The package 90 includes a packaging sheet 91 for packaging a plurality of absorbent articles 1 for pets. In FIG. 10, the absorbent article 1 for pets is packaged in the packaging sheet 91 in a state where the main body portion 2 is folded in three in the longitudinal direction Y. Note that the absorbent article 1 for pets may be accommodated in the packaging sheet 91 in a state where it is folded in four in the longitudinal direction Y. The packaging sheet 91 is made of, for example, a synthetic resin such as polyethylene, polypropylene, or polyethylene terephthalate.

[0097] Next, with reference to FIGS. 11 and 12, the procedure for folding the absorbent article 1 for pets will be described. First, as shown in FIG. 11, the front flap portion 11 is folded inward along the fold line L3 extending in the longitudinal direction Y so that the inner edge 44a in the short direction X of the front leak - proof sheet 41 is exposed. As shown in FIG. 2, the fold line L3 is located closer to the front edge 3 than the intermediate line between the front edge 3 and the inner edge 44a in the short direction X. That is, the distance between the front edge 3 and the fold line L3 in the short direction X is shorter than the distance between the inner edge 44a and the fold line L3 in the short direction X. 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 short direction X.

[0098] Next, as shown in FIG. 12, the main body portion 2 is folded into three folds 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 engaging portion 70 is engaged with the target portion 71. The absorbent article 1 for pets folded as described above is housed in the package 90.

[0099] As described above, in the package 90, when the folded absorbent article 1 for pets is unfolded in the longitudinal direction Y, the inner edge 44a in the short direction X of the front leak - proof sheet 41 is exposed. Thereby, even when the absorbent article 1 for pets is worn after unfolding the three - fold, the front leak - proof sheet 41 surely contacts the body of the pet, and as a result, urine leakage can be effectively suppressed by the front leak - proof sheet 41. Therefore, even when the absorbent article 1 for pets is worn without spreading the front flap portion 11, since the front leak - proof sheet 41 contacts the body of the pet, urine leakage can be suppressed by the front leak - proof sheet 41.

[0100] Also, in the package 90, since the rear flap portion 12 is not folded inside in the short side direction X, when the user takes out the pet absorbent article 1 from the package 90, the user can easily recognize the front and rear directions of the pet absorbent article 1. For example, since it is possible to easily recognize where the front leak-proof sheet 41 is located on the pet absorbent article 1, the pet absorbent article 1 can be easily attached so that the front leak-proof sheet 41 is disposed on the head side of the pet.

[0101] As described above, the pet absorbent articles according to various embodiments have been described. However, the present invention can be configured in various modified forms without being limited to the above-described embodiments without changing the gist of the invention. That is, it should be noted that the above-described embodiments are for illustrative purposes and do not limit the scope of the present invention.

[0102] For example, in each of the above-described pet absorbent articles 1, 1A, 1B, and 1C, the front leak-proof sheet 41 may not include the first elastic member 43, and the rear leak-proof sheet 51 may not include the first elastic member 53. Further, each of the pet absorbent articles 1, 1A, 1B, and 1C may not include a pair of leak-proof sheets 40.

[0103] In each of the above-described pet absorbent articles 1, 1A, 1B, and 1C, the surface sheet 15 in the first portion 2A and the surface sheet 15 in the second portion 2B may engage 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 engage with each other. The above-described various embodiments can be combined within a non-contradictory range.
