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

[0010] (Clause 1) A pet absorbent article according to one embodiment is to be worn by wrapping it around the waist of a pet. The pet absorbent article includes a first leak-proof sheet having a horizontally elongated shape having a longitudinal direction and a lateral direction, and including a main body portion having a first edge located on one side in the lateral direction and a second edge located on the other side in the lateral direction, a first fixing portion located on one side in the longitudinal direction and joined to the main body portion in a state of being folded inward in the lateral direction, a second fixing portion located on the other side in the longitudinal direction and joined to the main body portion in a state of being folded inward in the lateral direction, and a first standing portion that can stand between the first fixing portion and the second fixing portion along a first standing line extending along the first edge, and a first leak-proof sheet having a longitudinal direction and a lateral direction and including a first fixing portion that can be folded inward in the lateral direction and joined to the main body portion in a state of being folded inward in the lateral direction. and a second leak-proof sheet including a third fixed portion arranged on one side in the width direction and joined to the main body portion in a state of being folded inward in the width direction, a fourth fixed portion arranged on the other side in the length direction and joined to the main body portion in a state of being folded inward in the width direction, and a second upright portion that can stand between the third fixed portion and the fourth fixed portion along a second upright line extending along the second end edge, wherein the ratio of the length of the second upright portion in the length direction to the width of the second upright portion in the width direction is greater than the ratio of the length of the first upright portion in the length direction to the width of the first upright portion in the width direction.

[0011] In the pet absorbent article according to the above aspect, the second upright portions are raised between the third and fourth fixed portions. Therefore, urine flowing between the main body portion and the second upright portions is blocked by the third or fourth fixed portion and remains inside the main body portion. As a result, urine flowing between the main body portion and the second upright portions is prevented from leaking to the outside. Furthermore, in this pet absorbent article, the ratio of the length of the second upright portions in the longitudinal direction to the width of the second upright portions in the lateral direction is greater than the ratio of the length of the first upright portions in the longitudinal direction to the width of the first upright portions in the lateral direction. Because the second upright portions have a relatively elongated shape, the second upright portions are easily folded both inward and outward from the main body portion. Therefore, the second upright portions can be folded inward or outward from the main body portion depending on the pet's body shape, improving the fit of the second upright portions to the pet and thereby preventing urine leakage.

[0012] (Clause 2) In the pet absorbent article described in Clause 1, the widths of the third and fourth fixing portions in the short direction may be smaller than the widths of the first and second fixing portions in the short direction, and the lengths of the third and fourth fixing portions in the longitudinal direction may be shorter than the lengths of the first and second fixing portions in the longitudinal direction. In this case, the sizes of the third and fourth fixing portions that fix both ends of the second upright portion in the longitudinal direction are relatively small, making it easier to fold the second upright portion inward or outward from the main body portion depending on the pet's body shape. This further improves the fit of the second upright portion to the pet.

[0013] (Clause 3) In the pet absorbent article described in Clause 1 or 2, the main body portion may include a top sheet disposed on the skin-facing side, a back sheet disposed on the non-skin-facing side, and an absorbent disposed between the top sheet and the back sheet. The first and second fixing portions may be positioned so as to partially overlap the absorbent when viewed in the thickness direction of the main body portion, and the third and fourth fixing portions may be positioned so as not to overlap the absorbent when viewed in the thickness direction. In this case, urine that flows between the main body portion and the first upright portions is blocked by the first or second fixing portion and tends to remain inside the absorbent. This allows the absorbent portion to effectively absorb urine. Furthermore, by fixing both ends of the first upright portions to a high-rigidity region where the absorbent is located, the upright first upright portions are less likely to collapse. This allows the first leak-proof sheet to effectively block pet urine. Furthermore, by fixing both ends of the second upright portions to a low-rigidity region where the absorbent is not located, the second upright portions are more likely to collapse both inside and outside the main body portion. As a result, the second upright portions fit the pet better, and therefore, this absorbent article for pets can effectively prevent urine leakage.

[0014] (Clause 4) In the pet absorbent article described in any one of clauses 1 to 3, the width of each of the third and fourth fixed portions in the short-side direction may be at least half the width of the second upright portion in the short-side direction, and the second leak-proof sheet may include a non-fixed portion disposed between each of the third and fourth fixed portions and the second upright line and not joined to the main body portion. Because the second leak-proof sheet includes a non-fixed portion disposed between each of the third and fourth fixed portions and the second upright line, it is possible to reduce the amount of hot melt adhesive used to join both ends of the second upright portion to the main body portion in the long-side direction, thereby suppressing seepage of the hot melt adhesive. This prevents deterioration of the feel of the product due to seepage of the hot melt adhesive. Furthermore, because the width of each of the third and fourth fixed portions is at least half the width of the second upright portion, it is possible to prevent urine that has flowed between the main body portion and the second upright portion from leaking out through the non-fixed portion.

[0015] (Clause 5) In the absorbent article for pets described in any one of clauses 1 to 4, the inner edges of the third and fourth fixed parts in the short side direction may be partially inclined so as to be positioned outward in the short side direction as they approach the second upright part. In this case, the second upright part is more likely to collapse toward the outside of the main body part along the inclined parts of the inner edges of the third and fourth fixed parts.

[0016] (Clause 6) In the absorbent article for pets described in any one of clauses 1 to 5, the length of the second upright portions in the longitudinal direction may be longer than the length of the first upright portions in the longitudinal direction. In this case, since the length of the second upright portions is relatively long, the second upright portions are more likely to collapse both inward and outward from the main body portion. This improves the fit of the second upright portions to the pet, thereby effectively preventing urine leakage.

[0017] (Clause 7) In the pet absorbent article according to any one of clauses 1 to 6, the width of the first upright portions in the short side direction may be greater than the width of the second upright portions in the short side direction. In this case, because the width of the first upright portions is relatively large, when the pet absorbent article is worn with the first leak-proof sheet positioned toward the pet's head, the first leak-proof sheet can effectively block the pet's urine, thereby effectively preventing urine leakage.

[0018] (Clause 8) The pet absorbent article according to any one of clauses 1 to 7 may further include a first elastic member disposed along the inner edge of the first leak-barrier sheet in the short-side direction, a second elastic member disposed along the inner edge of the second leak-barrier sheet in the short-side direction, a third elastic member disposed between the first standing line and the first edge in the short-side direction, and a fourth elastic member disposed between the second standing line and the second edge in the short-side direction. In this case, contraction of the first elastic member facilitates the first standing portion to stand, and contraction of the second elastic member facilitates the second standing portion to stand. As a result, the first and second leak-barrier sheets can effectively block the pet's urine. Furthermore, the third and fourth elastic members expand and contract to accommodate changes in the pet's body shape and posture, improving the fit of the pet absorbent article to the pet. This effectively prevents urine leakage.

[0019] (Clause 9) In the absorbent article for pets described in Clause 8, the elongation ratio of the second elastic member may be lower than the elongation ratio of the first elastic member. By making the elongation ratio of the second elastic member relatively low, the second upright portions are less likely to stand up. As a result, the second upright portions are more likely to collapse both inside and outside the main body portion.

[0020] (Clause 10) In the absorbent article for pets described in clause 8 or 9, the elongation ratio of the fourth elastic member may be higher than the elongation ratio of the second elastic member. By relatively increasing the elongation ratio of the fourth elastic member, the contraction force of the region between the second standing line and the second edge (outside the second standing line) increases as the fourth elastic member contracts. As a result of the contraction of this region, the second standing portion is more likely to collapse outward from the main body portion.

[0021] (Clause 11) In the absorbent article for pets described in any one of clauses 8 to 10, the elongation ratio of the first elastic member may be equal to or greater than the elongation ratio of the third elastic member. In this case, the elongation ratio of the first elastic member is relatively high, making it easier for the first upstanding portion to stand up. As a result, the first leak-proof sheet can effectively block pet urine.

[0022] (Clause 12) In the absorbent article for pets according to any one of clauses 1 to 11, the width of the first upright portion in the lateral direction may be greater than the distance between the first upright line and the first edge in the lateral direction. In this case, the relatively large width of the first upright portion allows the first leak-proof sheet to effectively block pet urine.

[0023] (Clause 13) In the absorbent article for pets according to any one of clauses 1 to 12, the width of the second upright portion in the short side direction may be greater than the distance between the second upright line and the second edge in the short side direction. In this case, the relatively large width of the second upright portion allows the second leak-proof sheet to effectively block pet urine.

[0024] (Clause 14) In the absorbent article for pets according to any one of clauses 1 to 13, the distance between the second standing line and the second edge in the short direction may be greater than the width of the second standing portion in the short direction. In this case, since the distance between the second standing line and the second edge is relatively large, when urine passes over the second standing portion, the urine can be received in the area between the second standing line and the second edge. Therefore, urine leakage can be effectively suppressed.

[0025] (Clause 15) In the absorbent article for pets according to any one of clauses 1 to 14, the main body may include a top sheet disposed on the skin-facing side, a back sheet disposed on the non-skin-facing side, and an absorbent disposed between the top sheet and the back sheet, and the distance between the second edge in the short direction and the absorbent may be smaller than the distance between the first edge in the short direction and the absorbent. In this case, it is easy to position the pet's urination opening over the absorbent when the article is worn. Therefore, urine can be effectively absorbed by the absorbent.

[0026] (Clause 16) In the absorbent article for pets described in any one of Clauses 1 to 15, the main body portion may include a top sheet disposed on the skin-facing side, a back sheet disposed on the non-skin-facing side, and an absorbent disposed between the top sheet and the back sheet, wherein the distance between the first upright lines and the absorbent in the short direction may be smaller than the width of the first upright portions in the short direction, and the distance between the second upright lines and the absorbent in the short direction may be smaller than the width of the second upright portions in the short direction. By relatively increasing the width of the first upright portions in the short direction, excreted urine can be effectively blocked by the first upright portions. On the other hand, by relatively decreasing the distance between the second upright lines and the absorbent in the short direction, urine blocked by the second upright portions can be quickly absorbed by the absorbent.

[0027] (Clause 17) The pet absorbent article according to any one of clauses 1 to 16 may further include an inner elastic member disposed between the first and second upright lines and providing stretchability to the main body portion. In this case, the inner elastic member contracts to accommodate changes in the pet's body shape and posture, thereby improving the fit of the pet absorbent article. As a result, gaps are prevented from forming between the pet absorbent article and the pet's body, effectively preventing urine leakage.

[0028] (Clause 18) In the pet absorbent article according to any one of clauses 1 to 17, the first edge may be a front edge that is positioned on the front legs of the pet when the pet absorbent article is worn by the pet, and the second edge may be a rear edge that is positioned on the rear legs of the pet when the pet absorbent article is worn by the pet. In this case, leakage of urine that has flowed between the main body portion and the second upright portions that are positioned on the rear legs of the pet is suppressed. Furthermore, the fit of the second upright portions that are positioned on the rear legs of the pet is improved, thereby suppressing urine leakage.

[0029] (Clause 19) A package according to one embodiment contains the pet absorbent article according to any one of clauses 1 to 18. The main body of this pet absorbent article includes a first flap portion arranged along a first edge and a second flap portion arranged along a second edge, and the pet absorbent article is contained in the package with the main body folded in thirds or fourths in the longitudinal direction after the first flap portion is folded inward along a fold line extending in the longitudinal direction so that the inner edge of the first leak-barrier sheet in the transverse direction is exposed.

[0030] In the above-described embodiment, when the pet absorbent article is folded in thirds or fourths and unfolded in the longitudinal direction, the inner edge of the first leakproof sheet in the lateral direction is exposed. Therefore, even when the pet absorbent article is worn without unfolding the first flap portion, the first leakproof sheet comes into contact with the pet's body. Therefore, the first leakproof sheet can suppress urine leakage.

[0031] (Clause 20) In the packaging described in Clause 19, the second flap portion does not have to be folded inward in the short direction. By folding the first flap portion and not folding the second flap portion, the user can easily identify the front and rear orientations of the pet absorbent article when removing the pet absorbent article from the packaging. This makes it easier to put the pet absorbent article on the pet in the correct orientation.

[0032] [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 elements are given the same reference numerals, and duplicate explanations will be omitted. The drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional ratios are not limited to those shown in the drawings.

[0033] Hereinafter, an absorbent article for pets according to one embodiment will be described. Fig. 1 is a perspective view schematically showing an absorbent article for pets 1 according to one embodiment. Fig. 2 is a plan view of the absorbent article for pets 1 as viewed from the skin-facing side Z1. Fig. 3 is a plan view of the absorbent article for pets 1 as viewed from the non-skin-facing side Z2. Fig. 4 is a cross-sectional view of the absorbent article for pets 1 taken along line A-A in Fig. 2. The absorbent article for pets 1 shown in Figs. 1 to 4 is a disposable pet diaper that absorbs urine from pets.

[0034] 1 to 4 show the pet absorbent article 1 in an unfolded state. The unfolded state refers to a state in which the pet absorbent article 1 has been stretched to a state in which no wrinkles are formed. In contrast, the natural state refers to a state in which no external force is applied to the pet absorbent article 1. The skin-facing side Z1 is the side that faces the skin of the pet when the pet absorbent article 1 is worn, and the non-skin-facing side Z2 is the side that faces away from the skin of the pet when the pet absorbent article 1 is worn. In the following description, the person who puts the pet absorbent article 1 on a pet is referred to as the "user." Typically, the user is the pet's owner. In the following description, the positional relationship in the unfolded state will be described unless otherwise specified.

[0035] In this specification, "pets" broadly encompass vertebrates and invertebrates, typically including pets such as dogs, cats, rabbits, and hamsters. The pet absorbent article 1 is particularly suitable for use with male pets whose urethral openings are located forward of the base of the hind legs. As shown in FIG. 1 , the pet absorbent article 1 extends in a short direction X along the front-to-back direction of the pet (the direction connecting the head and buttocks) and a long direction Y along the pet's waist. The short direction X and the long direction Y are perpendicular to each other. The thickness direction Z is perpendicular to the short direction X and the long direction Y, and includes a skin-facing side Z1 that faces the pet's skin when worn, and a non-skin-facing side Z2 that faces away from the pet's skin when worn. The pet absorbent article 1 is worn by wrapping it around the pet's waist.

[0036] The pet absorbent article 1 includes a main body 2. The main body 2 has a generally rectangular (horizontally elongated) planar shape extending in a short direction X and a long direction Y. The four corners of the main body 2 are cut to narrow the width of the main body 2 in the short direction X. The four corners of the main body 2 do not have to be cut. The main body 2 has a front edge 3 (first edge) located at one end in the short direction X and a rear edge 4 (second edge) located at the other end in the short direction X. When the pet absorbent article 1 is worn on a pet, the front edge 3 is located near the pet's front legs, and the rear edge 4 is located near the pet's hind legs. 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 located at one end in the longitudinal direction Y and a second side edge 6 located at the other end in the longitudinal direction Y.

[0037] 2, the main body 2 has a first portion 2A arranged on one side in the longitudinal direction Y of a center line P1 of the main body 2 in the longitudinal direction Y, and a second portion 2B arranged on the other side in the longitudinal direction Y of the center line P1 of the main body 2 in the longitudinal direction Y. The first portion 2A is the region between the center line P1 and the first side edge 5, and the second portion 2B is the region between the center line P1 and the second side edge 6.

[0038] As shown in Figures 1 to 4, the main body 2 includes a topsheet 10, a backsheet 20, and an absorbent body 30. The topsheet 10 constitutes the surface of the main body 2 that comes into contact with a pet and is arranged on the skin-facing side Z1. The topsheet 10 is liquid permeable, allowing, for example, pet urine to pass through to the absorbent body 30. The topsheet 10 is located approximately in the center in the short direction X. The topsheet 10 is bonded to the backsheet 20 and the absorbent body 30 with, for example, a hot melt adhesive. Examples of nonwoven fabrics that constitute the topsheet 10 include air-through nonwoven fabrics, spunbond nonwoven fabrics, and point-bond nonwoven fabrics.

[0039] The backsheet 20 forms the surface of the main body 2 that is positioned on the outside when worn, and is arranged on the non-skin-facing side Z2. The backsheet 20 includes a liquid-impermeable back film 21 and a back nonwoven fabric 22 that is arranged closer to the non-skin-facing side Z2 than the back film 21. The width of the back film 21 in the short direction X is narrower than the width of the back nonwoven fabric 22, and the back nonwoven fabric 22 extends beyond the back film 21 on both sides in the short direction X. The back film 21 may have substantially the same width as the back nonwoven fabric 22. The back nonwoven fabric 22 forms the outermost layer of the pet absorbent article 1. Examples of nonwoven fabrics that form the back nonwoven fabric 22 include air-through nonwoven fabrics, spunbond nonwoven fabrics, and point-bond nonwoven fabrics. The back film 21 is bonded to the back nonwoven fabric 22 and the absorbent body 30, for example, with a hot melt adhesive.

[0040] The absorbent body 30 is disposed between the topsheet 10 and the backsheet 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.

[0041] The main body portion 2 includes a first end portion 7 disposed on one side in the longitudinal direction Y, a second end portion 8 disposed on the other side in the longitudinal direction Y, and a central portion 9 disposed between the first end portion 7 and the second end portion 8. In one embodiment, the first end portion 7 is a region located between the absorbent body 30 and the first side edge 5 in the longitudinal direction Y. The second end portion 8 is a region located between the absorbent body 30 and the second side edge 6 in the longitudinal direction Y. The central portion 9 is a region located 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 lateral direction X narrows as it approaches the first side edge 5, and the width of the second end portion 8 in the lateral direction X narrows as it approaches the second side edge 6. The narrowed widths of the first end portion 7 and the second end portion 8 make it easier for a user to grip the first end portion 7 and the second end portion 8. The first end 7 is part of the first portion 2A, and the second end 8 is part of the second portion 2B.

[0042] The main body 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 (first flap portion) is arranged along the front edge 3, and the rear flap portion 12 (second flap portion) is arranged along the rear edge 4.

[0043] 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. Examples of the pulp used in the absorbent core include chemical pulp, cellulose fiber, rayon, and acetate. Examples of the polymeric absorbent used include starch-based, acrylic acid-based, and amino acid-based particulate or fibrous polymers. The absorbent body 30 may be an SAP sheet primarily composed of SAP, without including pulp.

[0044] The pet absorbent article 1 further includes a pair of leakage preventing gathers 40. The pair of leakage preventing gathers 40 are provided on the top sheet 10 and are spaced apart from each other in the short direction X. The pair of leakage preventing gathers 40 are arranged so as to cover both side edges of the top sheet 10 in the short direction X from the skin-facing side Z1, and extend in the long direction Y over the entire length of the main body portion 2. The pair of leakage preventing gathers 40 are partially joined to the top sheet 10 or the back sheet 20 on the outside of the absorbent body 30 in the short direction X. The pair of leakage preventing gathers 40 stand up relative to the top sheet 10, thereby preventing pet urine excreted in the absorbent body 30 from leaking in the short direction X.

[0045] The pair of leakage preventing gathers 40 includes front leakage preventing gathers 41 provided along the front edge 3 and rear leakage preventing gathers 51 provided along the rear edge 4. In the embodiment shown in Fig. 4, the pair of leakage preventing gathers 40 are configured as individual members separated from the other members, but in one embodiment, the pair of leakage preventing gathers 40 may be formed by folding back the back surface nonwoven fabric 22 toward the topsheet 10 on the outside of the main body portion 2 in the short direction X. In this case, a part of the back surface nonwoven fabric 22 folded back toward the topsheet 10 constitutes the pair of leakage preventing gathers 40, and the other part of the back surface nonwoven fabric 22 constitutes the backsheet 20 of the main body portion 2.

[0046] The front leakproof gathers 41 include a front leakproof sheet 42 (first leakproof sheet) and a first elastic member 43 arranged along the inner edge 42a of the front leakproof sheet 42 in the short direction X. The front leakproof sheet 42 is arranged on one side in the short direction X (the front edge 3 side). The rear leakproof gathers 51 include a rear leakproof sheet 52 (second leakproof sheet) and a second elastic member 53 arranged along the inner edge 52a of the rear leakproof sheet 52 in the short direction X. The rear leakproof sheet 52 is arranged on the other side in the short direction X (the rear edge 4 side). The front leakproof sheet 42 and the rear leakproof sheet 52 are each made of a water-repellent or hydrophobic nonwoven fabric. For example, the front leakproof sheet 42 and the rear leakproof sheet 52 are made of spunlace nonwoven fabric, spunbond nonwoven fabric, thermalbond nonwoven fabric, meltblown nonwoven fabric, SMS nonwoven fabric, needlepunched nonwoven fabric, air-through nonwoven fabric, or the like.

[0047] FIG. 5 is a schematic diagram showing the configuration of the leak-barrier gathers 40. For ease of explanation, in FIG. 5, the areas of the front leak-barrier sheet 42 and the rear leak-barrier sheet 52 that are joined to the topsheet 10 are shaded. As shown in FIG. 5, the front leak-barrier sheet 42 includes a horizontal fixing portion 44, a first vertical fixing portion 45 (first fixing portion), a second vertical fixing portion 46 (second fixing portion), and a front standing portion 47 (first standing portion). The horizontal fixing portion 44, the first vertical fixing portion 45, and the second vertical fixing portion 46 are areas of the front leak-barrier sheet 42 that are joined to the topsheet 10. The front standing portion 47 is an area of ​​the front leak-barrier sheet 42 that is not joined to the topsheet 10. A front standing line 44a (first standing line) is formed at the boundary between the horizontal fixing portion 44 and the front standing portion 47, serving as a supporting point for the front standing portion 47 in the short direction X. An upright line 45a is formed at the boundary between the first vertical fixing part 45 and the front upright part 47, serving as an upright fulcrum for the front upright part 47 in the longitudinal direction Y. An upright line 46a is formed at the boundary between the second vertical fixing part 46 and the front upright part 47, serving as an upright fulcrum for the front upright part 47 in the longitudinal direction Y.

[0048] The lateral fixing parts 44 are arranged on one side in the short direction X (the front edge 3 side) of the absorber 30, and extend along the longitudinal direction Y. Note that a part of the front leak-proof sheet 42 arranged outside the lateral fixing parts 44 in the short direction X may also be fixed to the topsheet 10.

[0049] The first vertical fixing portion 45 is disposed on one side in the longitudinal direction Y (the side of the first side edge 5) and is joined to the main body portion 2 in a state of being bent inward in the short direction X. The second vertical fixing portion 46 is disposed on the other side in the longitudinal direction Y (the side of the second side edge 6) and is joined to the main body portion 2 in a state of being bent inward in the short direction X. Each of the first vertical fixing portion 45 and the second vertical fixing portion 46 is joined to the topsheet 10 with, for example, a hot melt adhesive. The first vertical fixing portion 45 and the second vertical fixing portion 46 partially overlap the absorbent body 30 when viewed from the thickness direction Z. In this case, urine that flows between the main body portion 2 and the front standing portion 47 is blocked by the first vertical fixing portion 45 or the second vertical fixing portion 46 and is therefore more likely to remain inside the absorbent body 30. This allows the absorbent body 30 to effectively absorb urine. Furthermore, by fixing both ends of the front standing portion 47 to the highly rigid region where the absorber 30 is located, the standing front standing portion 47 is less likely to collapse, thereby enabling the pet's urine to be effectively blocked by the front leak-proof sheet 42. Note that the first vertical fixing portion 45 and the second vertical fixing portion 46 do not have to overlap the absorber 30 when viewed from the thickness direction Z.

[0050] The first vertical fixing portion 45 and the second vertical fixing portion 46 are arranged at a distance inward in the short direction X from the horizontal fixing portion 44. The front leak-proof sheet 42 further includes a first non-fixing portion 48 arranged between the horizontal fixing portion 44 (front standing line 44a) and the first vertical fixing portion 45, and a second non-fixing portion 49 arranged between the horizontal fixing portion 44 (front standing line 44a) and the second vertical fixing portion 46. The first non-fixing portion 48 and the second non-fixing portion 49 are not joined to the main body 2.

[0051] The front standing line 44a is disposed between the center line P2 in the short direction X of the main body 2 and the front edge 3, and extends along the front edge 3. For example, the front standing line 44a is disposed between the front edge of the absorber 30 and the front edge 3. The front standing line 44a serves as a supporting point for the front standing portion 47 in the short direction X. Note that the front standing line 44a may partially overlap the absorber 30 when viewed from the thickness direction Z.

[0052] The standing line 45a 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 standing line 45a 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 standing line 45a serves as a standing fulcrum for the front standing portion 47 in the longitudinal direction Y. Note that the standing line 45a may also be disposed closer to the first side edge 5 than the absorber 30 in the longitudinal direction Y.

[0053] The standing line 46a 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 standing line 46a is disposed closer to the center line P1 than the edge of the absorber 30 on the second side edge 6 side in the longitudinal direction Y. The standing line 46a serves as a standing fulcrum for the front standing portion 47 in the longitudinal direction Y. Note that the standing line 46a may also be disposed closer to the second side edge 6 than the absorber 30 in the longitudinal direction Y.

[0054] As described above, the first region 42A of the front leakproof sheet 42, which is located closer to the first side edge 5 than the standing line 45a, is joined to the topsheet 10 in a state of leaning inward in the short direction X. In the embodiment shown in Fig. 5, the first region 42A includes a first vertical fixed portion 45 and a first non-fixed portion 48. Similarly, the second region 42B of the front leakproof sheet 42, which is located closer to the second side edge 6 than the standing line 46a, is joined to the topsheet 10 in a state of leaning inward in the short direction X. In the embodiment shown in Fig. 5, the second region 42B includes a second vertical fixed portion 46 and a second non-fixed portion 49. The first region 42A and the second region 42B of the front leakproof sheet 42 are fixed to the topsheet 10 and are non-standing regions that do not stand up.

[0055] In contrast, the front standing portion 47 is disposed between the first region 42A and the second region 42B (between the first vertical fixing portion 45 and the second vertical fixing portion 46) on the inside of the front standing line 44a in the short direction X, and is a region that is not joined to the main body 2. The front standing portion 47 can stand along the front standing line 44a between the first region 42A and the second region 42B. Note that, because the first region 42A and the second region 42B of the front leak-proof sheet 42 are joined to the main body 2, the front standing portion 47 is folded inward in the short direction X in the unfolded state, as shown in FIG.

[0056] 5, the first region 42A and the second region 42B include the first non-fixed portion 48 and the second non-fixed portion 49, respectively, so that the amount of hot melt adhesive used in the first region 42A and the second region 42B can be reduced. As a result, seepage of the hot melt adhesive can be suppressed, and deterioration of the feel against the skin due to the seepage of the hot melt adhesive can be suppressed. Note that the front leakproof sheet 42 may also be joined to the topsheet 10 with the hot melt adhesive at the first non-fixed portion 48 and the second non-fixed portion 49.

[0057] 4, a part of the inner portion of the front leak-proof sheet 42 in the short direction X is folded back toward the non-skin-facing side Z2, and a first elastic member 43 is disposed between the folded back front leak-proof sheet 42. The first elastic member 43 is made of a stretchable material such as rubber or spandex that is contractible in the longitudinal direction Y.

[0058] The first elastic members 43 are joined to the front leak-proof sheet 42 with a hot melt adhesive while stretched in the longitudinal direction Y. As a result, when the first elastic members 43 contract in the longitudinal direction Y, the front standing portions 47 of the front leak-proof sheet 42 contract in the longitudinal direction Y together with the first elastic members 43. As a result, the front standing portions 47 stand along the front standing lines 44a outside the short direction X of the absorber 30. The standing of the front standing portions 47 of the front leak-proof gathers 41 prevents pet urine from leaking forward along the surface of the topsheet 10.

[0059] The rear leakproof sheet 52 of the rear leakproof gathers 51 includes a horizontal fixing portion 54, a first vertical fixing portion 55 (third fixing portion), a second vertical fixing portion 56 (fourth fixing portion), and a rear standing portion 57 (second standing portion). The horizontal fixing portion 54, the first vertical fixing portion 55, and the second vertical fixing portion 56 are regions of the rear leakproof sheet 52 that are joined to the topsheet 10. The rear standing portion 57 is a region of the rear leakproof sheet 52 that is not joined to the topsheet 10. A rear standing line 54a (second standing line) that serves as a standing fulcrum for the rear standing portion 57 in the short direction X is formed at the boundary between the horizontal fixing portion 54 and the rear standing portion 57. A standing line 55a that serves as a standing fulcrum for the rear standing portion 57 in the longitudinal direction Y is formed at the boundary between the first vertical fixing portion 55 and the rear standing portion 57. An upright line 56 a is formed at the boundary between the second vertical fixing portion 56 and the rear upright portion 57 , and serves as an upright fulcrum for the rear upright portion 57 in the longitudinal direction Y.

[0060] The lateral fixing parts 54 are disposed on the other side in the short direction X (the rear edge 4 side) of the absorber 30, and extend along the longitudinal direction Y. Note that a part of the rear leakproof sheet 52 disposed outside the lateral fixing parts 54 in the short direction X may also be fixed to the topsheet 10.

[0061] The first vertical fixing portion 55 is disposed on one side in the longitudinal direction Y (the side of the first side edge 5) and is joined to the main body portion 2 in a state where it leans inward in the short direction X. The second vertical fixing portion 56 is disposed on the other side in the longitudinal direction Y (the side of the second side edge 6) and is joined to the main body portion 2 in a state where it leans inward in the short direction X. Each of the first vertical fixing portion 55 and the second vertical fixing portion 56 is joined to the topsheet 10 with, for example, a hot melt adhesive. The first vertical fixing portion 55 and the second vertical fixing portion 56 do not overlap the absorbent body 30 when viewed from the thickness direction Z. However, the first vertical fixing portion 55 and the second vertical fixing portion 56 may partially overlap the absorbent body 30 when viewed from the thickness direction Z.

[0062] The first vertical fixing portion 55 and the second vertical fixing portion 56 are arranged at a distance inward in the short direction X from the horizontal fixing portion 54. The rear leak-proof sheet 52 further includes a first non-fixing portion 58 arranged between the horizontal fixing portion 54 (rear standing line 54a) and the first vertical fixing portion 55, and a second non-fixing portion 59 arranged between the horizontal fixing portion 54 (rear standing line 54a) and the second vertical fixing portion 56. The first non-fixing portion 58 and the second non-fixing portion 59 are not joined to the main body 2.

[0063] The rear standing line 54a is disposed between the center line P2 in the short direction X of the main body 2 and the rear edge 4, and extends along the rear edge 4. For example, the rear standing line 54a is disposed between the rear edge of the absorber 30 and the rear edge 4. The rear standing line 54a serves as a supporting point for the rear standing portion 57 in the short direction X. The rear standing line 54a may partially overlap the absorber 30 when viewed from the thickness direction Z.

[0064] The standing line 55a 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 standing line 55a is 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. The standing line 55a serves as a standing fulcrum for the rear standing portion 57 in the longitudinal direction Y. Note that the standing line 55a may also be disposed closer to the center line P1 than the absorber 30 in the longitudinal direction Y.

[0065] The standing line 56a 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 standing line 56a is disposed closer to the second side edge 6 than the edge of the absorber 30 on the second side edge 6 side in the longitudinal direction Y. The standing line 56a serves as a standing fulcrum for the rear standing portion 57 in the longitudinal direction Y. Note that the standing line 56a may also be disposed closer to the center line P1 than the absorber 30 in the longitudinal direction Y.

[0066] As described above, the first region 52A of the rear leakproof sheet 52, which is located closer to the first side edge 5 than the standing line 55a, is joined to the topsheet 10 in a state of leaning inward in the short direction X. In the embodiment shown in Fig. 5, the first region 52A includes a first vertical fixed portion 55 and a first non-fixed portion 58. Similarly, the second region 52B of the rear leakproof sheet 52, which is located closer to the second side edge 6 than the standing line 56a, is joined to the topsheet 10 in a state of leaning inward in the short direction X. In the embodiment shown in Fig. 5, the second region 52B includes a second vertical fixed portion 56 and a second non-fixed portion 59. The first region 52A and the second region 52B of the rear leakproof sheet 52 are fixed to the topsheet 10 and are non-standing regions that do not stand up.

[0067] In contrast, the rear upright portion 57 is disposed between the first region 52A and the second region 52B (between the first vertical fixing portion 55 and the second vertical fixing portion 56) on the inside of the rear upright line 54a in the short-side direction X, and is a region that is not joined to the main body 2. The rear upright portion 57 can stand along the rear upright line 54a between the first region 52A and the second region 52B. Note that because the first region 52A and the second region 52B of the rear leak-proof sheet 52 are joined to the main body 2, the rear upright portion 57 is folded inward in the short-side direction X in the unfolded state, as shown in FIG.

[0068] Because the rear standing portion 57 stands between the first vertical fixing portion 55 and the second vertical fixing portion 56, urine that flows between the main body portion 2 and the rear standing portion 57 and flows along the horizontal fixing portion 54 is blocked by the first vertical fixing portion 55 or the second vertical fixing portion 56 and remains inside the main body portion 2. As a result, leakage of the pet's urine to the outside of the pet absorbent article 1 is suppressed.

[0069] 5 , the first region 52A and the second region 52B include the first non-fixed portion 58 and the second non-fixed portion 59, respectively, so that the amount of hot melt adhesive used to fix the first region 52A and the second region 52B can be reduced. As a result, it is possible to prevent the hot melt adhesive from seeping out to the skin-facing side Z1 during bonding, which would otherwise deteriorate the feel of the pet absorbent article 1. Note that the rear leakproof sheet 52 may also be joined to the topsheet 10 with the hot melt adhesive at the first non-fixed portion 58 and the second non-fixed portion 59.

[0070] 4, a part of the inner portion of the rear leakproof sheet 52 in the short direction X is folded back toward the non-skin-facing side Z2, and a second elastic member 53 is disposed between the folded back rear leakproof sheet 52. The second elastic member 53 is made of a stretchable material such as rubber or spandex that is contractible in the longitudinal direction Y.

[0071] The second elastic members 53 are joined to the rear leak-proof sheet 52 with a hot melt adhesive while stretched in the longitudinal direction Y. As a result, when the second elastic members 53 contract in the longitudinal direction Y, the rear upright portions 57 of the rear leak-proof sheet 52 contract in the longitudinal direction Y together with the second elastic members 53. As a result, the rear upright portions 57 stand up along the rear upright lines 54a on the outside of the absorber 30 in the short direction X. The standing upright rear upright portions 57 of the rear leak-proof gathers 51 prevent pet urine from leaking along the surface of the topsheet 10 to the rear.

[0072] Each of the first vertical fixing portion 45, the second vertical fixing portion 46, the first vertical fixing portion 55, and the second vertical fixing portion 56 is joined to the main body portion 2 so that the joined state will not be released even if a force greater than a predetermined value is applied to the joined portion (for example, when the joined portion is in contact with the pet when the pet absorbent article 1 is worn and the pet's body movement applies a force to the joined portion in a direction that releases the joint). The first vertical fixing portion 45, the second vertical fixing portion 46, the first vertical fixing portion 55, and the second vertical fixing portion 56 may be joined to the main body portion 2 by the same joining method. In the embodiment shown in Fig. 5, the first vertical fixing portion 45, the second vertical fixing portion 46, the first vertical fixing portion 55, and the second vertical fixing portion 56 are all joined to the main body portion 2 with a hot melt adhesive. The force per unit area required to peel each of the first vertical fixing portion 55 and the second vertical fixing portion 56 from the main body portion 2 may be substantially the same as the force per unit area required to peel each of the first vertical fixing portion 45 and the second vertical fixing portion 46 from the main body portion 2. For example, the amount of hot melt adhesive applied per unit area of ​​each of the first vertical fixing portion 55 and the second vertical fixing portion 56 may be substantially the same as the amount of hot melt adhesive applied per unit area of ​​each of the first vertical fixing portion 45 and the second vertical fixing portion 46. Note that the first vertical fixing portion 45, the second vertical fixing portion 46, the first vertical fixing portion 55, and the second vertical fixing portion 56 may be mechanically joined to the main body portion 2 by embossing or the like. The first vertical fixing portion 45, the second vertical fixing portion 46, the first vertical fixing portion 55, and the second vertical fixing portion 56 may be joined to the main body portion 2 by sonic processing.

[0073] In one embodiment, the pet absorbent article 1 further includes a third elastic member 61, a fourth elastic member 62, and a plurality of inner elastic members 63. The third elastic member 61, the fourth elastic member 62, and the plurality of inner elastic members 63 are made of a stretchable material such as rubber, a stretchable nonwoven fabric, a stretchable film, or spandex, and are stretchable in the longitudinal direction Y. The number of third elastic members 61, fourth elastic members 62, and inner elastic members 63 may be two or more. As shown in FIG. 4 , the third elastic member 61 and the fourth elastic member 62 are disposed, for example, between a pair of leakage-preventing gathers 40 and the backsheet 20 (back surface nonwoven fabric 22). The inner elastic member 63 is disposed between the topsheet 10 and the backsheet 20. The third elastic member 61, the fourth elastic member 62, and the inner elastic member 63 stretch to accommodate changes in the pet's body shape and posture in the longitudinal direction Y (for example, when the pet twists its body).

[0074] The third elastic member 61 is provided between the front standing line 44a and the front end edge 3 in the short direction X, and extends in the longitudinal direction Y. The third elastic member 61 is disposed between the front leakage preventing gathers 41 and the back sheet 20. The third elastic member 61 is joined to the main body portion 2 with a hot melt adhesive in a state stretched in the longitudinal direction Y. The third elastic member 61 is joined to the front leakage preventing sheet 42 of the front leakage preventing gathers 41 and the back nonwoven fabric 22. The third elastic member 61 imparts stretchability to the main body portion 2.

[0075] The fourth elastic member 62 is provided between the rear standing line 54a and the rear end edge 4 in the short direction X, and extends in the longitudinal direction Y. The fourth elastic member 62 is disposed between the rear leakage preventing gathers 51 and the backsheet 20. The fourth elastic member 62 is joined to the main body portion 2 with a hot melt adhesive in a state stretched in the longitudinal direction Y. The fourth elastic member 62 is joined to the rear leakage preventing sheet 52 of the rear leakage preventing gathers 51 and the back nonwoven fabric 22. The fourth elastic member 62 imparts stretchability to the main body portion 2.

[0076] 2 and 5 , the inner elastic members 63 are disposed between the front standing line 44a and the rear standing line 54a in the short direction X, imparting stretchability 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, imparting stretchability to the first end portion 7. More specifically, the plurality of inner elastic members 63 extend between the absorbent body 30 and an engaging portion 70, which will be described later. The inner elastic members 63 are disposed on the non-skin-facing side Z2 of the topsheet 10. For example, the inner elastic members 63 are disposed between the topsheet 10 and the back surface film 21, and are joined to the topsheet 10 and the back surface film 21 with a hot melt adhesive while being stretched in the longitudinal direction Y.

[0077] 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 elongated in the short direction X and is provided at the first end 7 of the first portion 2A. The engagement portion 70 is provided on the surface of the topsheet 10. The engagement portion 70 is, for example, a mechanical fastener having multiple hooks, and is capable of engaging with the backsheet 20 of the second portion 2B from the non-skin-facing side Z2. The engagement portion 70 may also engage with a portion of the topsheet 10 in the second portion 2B. In other words, a portion of the topsheet 10 in the first portion 2A may be engaged with another portion of the topsheet 10 in the second portion 2B.

[0078] In one embodiment, a target portion 71 is provided on the outer surface of the back sheet 20 of the second portion 2B. As shown in Fig. 3, the target portion 71 is, for example, a mechanical fastener having a plurality of loops that engage with a plurality of hooks of the engagement portion 70, and has a rectangular shape that is long in the longitudinal direction Y. 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. Note that the engagement portion 70 may also be capable of directly engaging with the back sheet 20.

[0079] Next, the dimensions of each component of the pet absorbent article 1 will be described with reference to Figures 5 and 6. Figure 6 is an enlarged plan view of a portion of the pet absorbent article 1 shown in Figure 5. In the following description, as shown in Figure 5, the width of the first vertical fixing portion 45 in the short-side direction X will be referred to as width W1, the width of the second vertical fixing portion 46 in the short-side direction X will be referred to as width W2, and the width of the front upright portion 47 in the short-side direction X will be referred to as width W3. Note that if the widths of the first vertical fixing portion 45 and the second vertical fixing portion 46 vary partially in the longitudinal direction Y, the maximum widths of the first vertical fixing portion 45 and the second vertical fixing portion 46 in the short-side direction X will be referred to as width W1 and width W2, respectively. Furthermore, the width W3 of the front upright portion 47 refers to the distance between the inner edge 42a of the front leak-proof sheet 42 and the front upright line 44a in the short-side direction X.

[0080] In the following description, the length of the first vertical fixing portion 45 in the longitudinal direction Y will be referred to as length L1, the length of the second vertical fixing portion 46 in the longitudinal direction Y will be referred to as length L2, and the length of the front upright portion 47 in the longitudinal direction Y will be referred to as length L3. Note that if the lengths of the first vertical fixing portion 45 and the second vertical fixing portion 46 vary partially in the short direction X, the maximum lengths of the first vertical fixing portion 45 and the second vertical fixing portion 46 in the longitudinal direction Y will be referred to as length L1 and length L2, respectively. Furthermore, the length L3 of the front upright portion 47 means the distance between the first vertical fixing portion 45 and the second vertical fixing portion 46 in the longitudinal direction Y.

[0081] Furthermore, in the following description, the width of the first vertical fixing portion 55 in the short direction X will be referred to as width W4, the width of the second vertical fixing portion 56 in the short direction X will be referred to as width W5, and the width of the rear upright portion 57 in the short direction X will be referred to as width W6. Note that if the widths of the first vertical fixing portion 55 and the second vertical fixing portion 56 vary partially in the longitudinal direction Y, the maximum widths of the first vertical fixing portion 55 and the second vertical fixing portion 56 in the short direction X will be referred to as width W4 and width W5, respectively. Furthermore, the width W6 of the rear upright portion 57 means the distance in the short direction X between the inner edge 52a of the rear leakproof sheet 52 and the rear upright line 54a.

[0082] In the following description, the length of the first vertical fixing portion 55 in the longitudinal direction Y will be referred to as length L4, the length of the second vertical fixing portion 56 in the longitudinal direction Y will be referred to as length L5, and the length of the rear upright portion 57 in the longitudinal direction Y will be referred to as length L6. Note that if the lengths of the first vertical fixing portion 55 and the second vertical fixing portion 56 vary partially in the short direction X, the maximum lengths of the first vertical fixing portion 55 and the second vertical fixing portion 56 in the longitudinal direction Y will be referred to as length L4 and length L5, respectively. Furthermore, the length L6 of the rear upright portion 57 means the distance between the first vertical fixing portion 55 and the second vertical fixing portion 56 in the longitudinal direction Y.

[0083] The width W1 of the first vertical fixed portion 45 is smaller than the width W3 of the front standing portion 47 by the width of the first non-fixed portion 48 in the short side direction X. The width W2 of the second vertical fixed portion 46 is smaller than the width W3 of the front standing portion 47 by the width of the second non-fixed portion 49 in the short side direction X.

[0084] The width W1 of the first vertical fixing portion 45 may be substantially the same as the width W2 of the second vertical fixing portion 46, and the length L1 of the first vertical fixing portion 45 may be substantially the same as the length L2 of the second vertical fixing portion 46. In this case, the area of ​​the first vertical fixing portion 45 is substantially the same as the area of ​​the second vertical fixing portion 46 when viewed from the thickness direction Z.

[0085] The width W4 of the first vertical fixed portion 55 is smaller than the width W6 of the rear upright portion 57 by the width of the first non-fixed portion 58 in the short-side direction X. The width W5 of the second vertical fixed portion 56 is smaller than the width W6 of the rear upright portion 57 by the width of the second non-fixed portion 59 in the short-side direction X. The width W4 of the first vertical fixed portion 55 and the width W5 of the second vertical fixed portion 56 may each be half or more of the width W6 of the rear upright portion 57. In this case, the width W4 of the first vertical fixed portion 55 is larger than the width of the first non-fixed portion 58 in the short-side direction X, and the width W5 of the second vertical fixed portion 56 is larger than the width of the second non-fixed portion 59 in the short-side direction X. By making the widths of the first non-fixed portion 58 and the second non-fixed portion 59 relatively small, it is possible to prevent urine that has flowed between the main body portion 2 and the rear upright portion 57 from leaking to the outside through the first non-fixed portion 58 or the second non-fixed portion 59.

[0086] In one embodiment, the width W4 of the first vertical fixing portion 55 may be substantially the same as the width W5 of the second vertical fixing portion 56, and the length L4 of the first vertical fixing portion 55 may be longer than the length L5 of the second vertical fixing portion 56. In this case, the area of ​​the first vertical fixing portion 55 is larger than the area of ​​the second vertical fixing portion 56 when viewed from the thickness direction Z.

[0087] In the embodiment shown in FIG. 5 , the width W3 of the front upright portion 47 is greater than the width W6 of the rear upright portion 57. Furthermore, the length L6 of the rear upright portion 57 is greater than the length L3 of the front upright portion 47. Therefore, the ratio of the length L6 of the rear upright portion 57 to the width W6 of the rear upright portion 57 is greater than the ratio of the length L3 of the front upright portion 47 to the width W3 of the front upright portion 47. Because the rear upright portion 57 has a relatively elongated shape, the rear upright portion 57 is more likely to collapse both inward and outward from the main body 2. For example, if the pet's genitals are located in the front, the rear upright portion 57 will collapse inward from the main body 2, making it easier for the rear upright portion 57 to fit snugly against the pet's genitals. If the pet's genitals are located in the rear, the rear upright portion 57 will collapse outward from the main body 2, making it easier for the rear upright portion 57 to embrace the pet's genitals. In this way, the rear standing portion 57 can be tilted inward or outward from the main body portion 2 depending on the pet's body shape, improving the fit of the rear standing portion 57 to the pet and, as a result, reducing urine leakage.

[0088] The width W4 of the first vertical fixing portion 55 and the width W5 of the second vertical fixing portion 56 are smaller than the width W1 of the first vertical fixing portion 45 and the width W2 of the second vertical fixing portion 46, respectively. Furthermore, the length L4 of the first vertical fixing portion 55 and the length L5 of the second vertical fixing portion 56 are shorter than the length L1 of the first vertical fixing portion 45 and the length L2 of the second vertical fixing portion 46, respectively. That is, the area of ​​the first vertical fixing portion 55 is smaller than the area of ​​the first vertical fixing portion 45 when viewed from the thickness direction Z, and the area of ​​the second vertical fixing portion 56 is smaller than the area of ​​the second vertical fixing portion 46 when viewed from the thickness direction Z. The relatively small sizes of the first vertical fixing portion 55 and the second vertical fixing portion 56, which secure both ends of the rear standing portion 57 in the longitudinal direction Y, make it easier to tilt the rear standing portion 57 inward or outward from the main body 2 depending on the pet's body shape. 5 , the width W4 of the first vertical fixing portion 55 and the width W5 of the second vertical fixing portion 56 are each smaller than the width W1 of the first vertical fixing portion 45 and the width W2 of the second vertical fixing portion 46. Furthermore, the length L4 of the first vertical fixing portion 55 and the length L5 of the second vertical fixing portion 56 are each shorter than the length L1 of the first vertical fixing portion 45 and the length L2 of the second vertical fixing portion 46.

[0089] As described above, the first vertical fixing portion 55 and the second vertical fixing portion 56 do not overlap the absorber 30 when viewed from the thickness direction Z. By fixing both ends of the rear standing portion 57 to a low-rigidity area where the absorber 30 is not located, the rear standing portion 57 becomes more likely to collapse both inside and outside the main body portion 2.

[0090] 6, the distance between the front edge 3 and the absorbent body 30 in the short direction X will be referred to as distance D1, the distance between the front standing line 44a and the front edge 3 in the short direction X will be referred to as distance D2, and the distance between the front standing line 44a and the absorbent body 30 in the short direction X will be referred to as distance D3. Also, the distance between the rear edge 4 and the absorbent body 30 in the short direction X will be referred to as distance D4, the distance between the rear standing line 54a and the rear edge 4 in the short direction X will be referred to as distance D5, and the distance between the rear standing line 54a and the absorbent body 30 in the short direction X will be referred to as distance D6.

[0091] As shown in FIG. 6 , the width W3 of the front upright portion 47 may be greater than the distance D2 between the front upright line 44a and the front edge 3, and the distance D5 between the rear upright line 54a and the rear edge 4 may be greater than the width W6 of the rear upright portion 57. As described above, by relatively increasing the width W3 of the front upright portion 47, the front leak-proof sheet 42 can effectively block pet urine excreted toward the front. Furthermore, because the distance D5 between the rear upright line 54a and the rear edge 4 is relatively large, even if urine exceeds the rear upright portion 57, it can be received in the area between the rear upright line 54a and the rear edge 4, thereby retaining the urine inside the rear edge 4. Therefore, urine leakage can be effectively prevented. The distance D2 between the front upright line 44a and the front edge 3 may be greater than the width W3 of the front upright portion 47.

[0092] In one embodiment, the distance D4 between the rear edge 4 and the absorbent body 30 may be smaller than the distance D1 between the front edge 3 and the absorbent body 30. By making the distance D4 between the rear edge 4 and the absorbent body 30 relatively small, it becomes easier to position the pet's urination opening above the absorbent body 30 when the pet absorbent article 1 is worn. Therefore, urine can be effectively absorbed by the absorbent body 30.

[0093] In one embodiment, the distance D3 between the front standing line 44a and the absorber 30 may be smaller than the width W3 of the front standing portion 47, and the distance D6 between the rear standing line 54a and the absorber 30 may be smaller than the width W6 of the rear standing portion 57. As shown in Fig. 6, when the front standing line 44a and the rear standing line 54a are positioned so as not to overlap the absorber 30, by making the distances D3 and D6 relatively small, the front standing line 44a and the rear standing line 54a are positioned close to the absorber 30, so that urine blocked by the front standing portion 47 and the rear standing portion 57 can be reliably absorbed by the absorber 30.

[0094] Next, the relationship between the elongation ratios of the first elastic member 43, the second elastic member 53, the third elastic member 61, and the fourth elastic member 62 will be described. The elongation ratio indicates the degree of elongation when the natural length of these elastic members is set to 1. The natural length of an elastic member is the length of the elastic member when no external force is applied. For example, the elongation ratio of the first elastic member 43 can be calculated by dividing the length of the first elastic member 43 when worn by the wearer by the length of the first elastic member 43 in its natural state. The greater the elongation ratio, the greater the contractile force of the elastic member when worn.

[0095] In one embodiment, the extension ratio of the second elastic members 53 may be lower than the extension ratio of the first elastic members 43. By setting the extension ratio of the second elastic members 53 relatively low, the rear standing portions 57 are less likely to stand up. As a result, the rear standing portions 57 are more likely to collapse both inside and outside the main body portion 2.

[0096] In one embodiment, the extension ratio of the fourth elastic member 62 may be higher than the extension ratio of the second elastic member 53. By making the extension ratio of the fourth elastic member 62 relatively higher, the contractile force of the region between the rear standing line 54a and the rear edge 4 (outside the rear standing line 54a) increases as the fourth elastic member 62 contracts. As a result of the contraction of this region, the rear standing portion 57 becomes more likely to collapse outward from the main body portion 2.

[0097] In one embodiment, the extension ratio of the first elastic members 43 may be equal to or greater than the extension ratio of the third elastic members 61. In this case, by making the extension ratio of the first elastic members 43 relatively high, the front standing portions 47 tend to stand up easily. As a result, the front leak-proof sheet 42 can effectively block pet urine.

[0098] Next, referring to FIG. 7 , the procedure for putting the pet absorbent article 1 on a pet will be described. First, the user presses the second end 8 of the pet absorbent article 1 against the pet's back and holds the area near the second end 8 with one hand. Next, the user holds the first end 7 of the pet absorbent article 1 with the other hand and wraps the pet absorbent article 1 around the pet's abdomen. At this time, the pet absorbent article 1 is put on so that the front leakage-preventing gathers 41 are positioned in front of the pet's urethral opening and the rear leakage-preventing gathers 51 are positioned behind the pet's urethral opening. Next, the user pulls the first end 7 upward so that the pet absorbent article 1 fits snugly around the pet's waist, and then engages the engaging portion 70 of the first end 7 with the target portion 71. By engaging the engaging portion 70 with the target portion 71 in this manner, the pet absorbent article 1 can be put on the pet in an appropriate position.

[0099] [Modifications] Fig. 8 is an enlarged plan view of a portion of a pet absorbent article 1A according to a first modification. In the embodiment shown in Fig. 6, the distance D5 between the rear standing line 54a and the rear edge 4 is greater than the width W6 of the rear standing portion 57. However, the pet absorbent article 1A differs from the pet absorbent article 1 in that the width W6 of the rear standing portion 57 is greater than the distance D5 between the rear standing line 54a and the rear edge 4.

[0100] In the pet absorbent article 1A, the width W3 of the front upright portion 47 is greater than the distance D2 between the front upright line 44a and the front edge 3, and the width W6 of the rear upright portion 57 is greater than the distance D5 between the rear upright line 54a and the rear edge 4. Because the widths W3 of the front upright portion 47 and W6 of the rear upright portion 57 are relatively large, the pet's urine can be effectively blocked by the front leak-proof sheet 42 and the rear leak-proof sheet 52. Furthermore, because the width W3 of the front upright portion 47 is greater than the distance D2 between the front upright line 44a and the front edge 3, the portion of the main body 2 between the front upright line 44a and the front edge 3 is prevented from coming into contact with the pet when the pet absorbent article 1A is worn. Furthermore, because the width W6 of the rear standing portion 57 is greater than the distance D5 between the rear standing line 54a and the rear edge 4, the portion of the main body 2 between the rear standing line 54a and the rear edge 4 is prevented from coming into contact with the pet when the pet absorbent article 1A is worn. Therefore, the third elastic member 61 disposed between the front standing line 44a and the front edge 3 and the fourth elastic member 62 disposed between the rear standing line 54a and the rear edge 4 are prevented from coming into contact with the pet, and as a result, deterioration in the feel of the pet absorbent article 1A can be prevented.

[0101] Fig. 9 is a plan view of a pet absorbent article 1B according to a second modification, as viewed from the skin-facing side Z1. In the embodiment shown in Fig. 5, the inner edges of each of the first vertical fixing part 55 and the second vertical fixing part 56 in the short direction X extend parallel to the longitudinal direction Y, but pet absorbent article 1B differs from pet absorbent article 1 in that the inner edges of each of the first vertical fixing part 55 and the second vertical fixing part 56 are partially inclined or curved.

[0102] As shown in Fig. 9 , the inner edge 55b of the first vertical fixing part 55 in the short side direction X is partially inclined or curved so as to be positioned outward in the short side direction X as it approaches the rear standing part 57. The inner edge 56b of the second vertical fixing part 56 in the short side direction X is partially inclined so as to be positioned outward in the short side direction X as it approaches the rear standing part 57. The inclined part of the inner edge 55b corresponds to the standing line 55a, and the inclined part of the inner edge 56b corresponds to the standing line 56a. In other words, in the pet absorbent article 1B, each of the standing lines 55a, 56a is inclined with respect to the longitudinal direction Y. In the pet absorbent article 1B, the rear standing part 57 is more likely to collapse toward the outside of the main body part 2 along these inclined standing lines 55a, 56a.

[0103] Next, a packaging body 90 for storing a plurality of pet absorbent articles 1 will be described. Fig. 10 is a cross-sectional view showing the 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 thirds in the longitudinal direction Y. The pet absorbent articles 1 may also be packaged in the packaging sheet 91 with the main body 2 folded in fours in the longitudinal direction Y. The packaging sheet 91 is made of a synthetic resin such as polyethylene, polypropylene, or polyethylene terephthalate.

[0104] Next, with reference to Figures 11 and 12, a procedure for folding the pet absorbent article 1 will be described. First, as shown in Figure 11, the front flap portion 11 is folded inward along a fold line AL extending in the longitudinal direction Y so that the inner edge 42a of the front leak-proof sheet 42 in the transverse direction X is exposed. As shown in Figure 2, the fold line AL is located closer to the front edge 3 than the midline between the front edge 3 and the inner edge 42a in the transverse direction X. That is, the distance between the front edge 3 and the fold line AL in the transverse direction X is shorter than the distance between the inner edge 42a and the fold line AL in the transverse direction X. By folding the front flap portion 11 along this fold line AL, the inner edge 42a of the front leak-proof sheet 42 is exposed. On the other hand, the rear flap portion 12 is not folded inward in the transverse direction X.

[0105] Next, as shown in Fig. 12, the main body portion 2 is folded in thirds 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 pet absorbent article 1 folded as described above is contained in a packaging body 90.

[0106] As described above, in the package 90, when the folded pet absorbent article 1 is unfolded in the longitudinal direction Y, the inner edge 42a of the front leakproof sheet 42 in the short direction X is exposed. This ensures that the front leakproof sheet 42 comes into contact with the pet's body even when the pet absorbent article 1 is worn after being unfolded from its third fold, and as a result, urine leakage can be effectively prevented by the front leakproof sheet 42. Therefore, even when the pet absorbent article 1 is worn without unfolding the front flap portion 11, the front leakproof sheet 42 comes into contact with the pet's body, and therefore urine leakage can be prevented by the front leakproof sheet 42.

[0107] 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 pet absorbent article 1 when removing the pet absorbent article 1 from the packaging body 90. For example, since the user can easily recognize where the front leak-proof sheet 42 is located in the pet absorbent article 1, the pet absorbent article 1 can be easily put on so that the front leak-proof sheet 42 is positioned near the pet's head.

[0108] Although various embodiments and modifications of absorbent articles for pets have been described above, the present invention is not limited to the above-described embodiments and modifications, and various modifications can be made without departing from the spirit of the invention. In other words, it should be noted that the above-described embodiments and modifications are intended to be illustrative and do not limit the scope of the present invention.

[0109] For example, in each of the above-described pet absorbent articles 1, 1A, and 1B, the engagement portion 70 is provided on the surface of the topsheet 10 at the first end 7 of the first portion 2A, but the engagement portion 70 may also be provided on the outer surface of the backsheet 20 at the first end 7 of the first portion 2A. In this case, the engagement portion 70 directly engages with the surface of the topsheet 10. The engagement portion 70 may also engage with the topsheet 10 via a target portion provided on the topsheet 10. The engagement portion 70 may also engage with a portion of the backsheet 20 in the second portion 2B. In other words, a portion of the backsheet 20 in the first portion 2A and another portion of the backsheet 20 in the second portion 2B may be engaged with each other.

[0110] Each of the above-described pet absorbent articles 1, 1A, 1B does not necessarily have to include the first elastic member 43, the second elastic member 53, the third elastic member 61, and the fourth elastic member 62.

[0111] If the front edge 3 is defined as the first edge, the rear edge 4 as the second edge, the front leak-proof sheet 42 as the first leak-proof sheet, and the rear leak-proof sheet 52 as the second leak-proof sheet, in each of the above-described pet absorbent articles 1, 1A, and 1B, when the pet absorbent article 1, 1A, or 1B is worn on a pet, the first edge may be positioned on the pet's hind legs and the second edge may be positioned on the pet's front legs. In other words, the first leak-proof sheet may be positioned on the pet's hind legs, and the second leak-proof sheet may be positioned on the pet's front legs. In this case, for example, when the pet absorbent article 1, 1A, or 1B is worn on an elderly dog, urine leakage from the pet's rear can be effectively suppressed. The various embodiments and modifications described above can be combined within a consistent range.
