[0003] Japanese Patent Application Laid-Open No. 2020-000182

[0004] In the absorbent article described above, when the engaging portion is peeled from the second region, damage such as pilling or tearing may occur to the main body portion. If damage occurs to the main body portion, it may become difficult for the engaging portion to engage with the second region, which may result in a decrease in the wearability of the absorbent article. Furthermore, damage to the main body portion may also cause a decrease in the feel against the skin.

[0005] Therefore, an object of the present disclosure is to suppress damage to an absorbent article for pets that occurs when an engaging portion separates.

[0006] In one aspect, there is provided an absorbent article for pets to be worn by wrapping it around the waist of a pet, the absorbent article for pets having a horizontally elongated shape having a longitudinal direction and a lateral direction, a main body portion including a top sheet arranged on the skin-facing side, a back sheet arranged on the non-skin-facing side, and an absorbent body arranged between the top sheet and the back sheet, the main body portion having a first portion arranged on one longitudinal side of a center line of the main body portion in the longitudinal direction and a second portion arranged on the other longitudinal side of the center line of the main body portion in the longitudinal direction, and an engaging portion provided on the first portion for engaging the first portion with the second portion, the main body portion including a compressed region formed on at least one of the top sheet and the back sheet and having one or more compressed portions recessed in the thickness direction of the main body portion, and the proportion of the area of ​​the one or more compressed portions formed in the second portion to the area of ​​the second portion is equal to or greater than the proportion of the area of ​​the one or more compressed portions formed in the first portion to the area of ​​the first portion.

[0007] According to various aspects of the present invention, damage to the absorbent article for pets due to separation of the engagement portion can be suppressed.

[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 worn by wrapping it around the waist of a pet. The pet absorbent article comprises a main body portion having a horizontally elongated shape having a longitudinal direction and a lateral direction, the main body portion including a top sheet arranged on the skin-facing side, a back sheet arranged on the non-skin-facing side, and an absorbent body arranged between the top sheet and the back sheet, the main body portion having a first portion arranged on one side of a longitudinal center line of the main body portion and a second portion arranged on the other side of the longitudinal center line of the main body portion, and an engaging portion provided on the first portion for engaging the first portion with the second portion, the main body portion including a compressed region formed on at least one of the top sheet and the back sheet and having one or more compressed portions recessed in the thickness direction of the main body portion, the proportion of the area of ​​the one or more compressed portions formed in the second portion to the area of ​​the second portion being equal to or greater than the proportion of the area of ​​the one or more compressed portions formed in the first portion to the area of ​​the first portion.

[0011] In the pet absorbent article according to the above aspect, the compressed portions formed in the second portion account for a relatively large proportion of the area of ​​the second portion out of the one or more compressed portions, thereby increasing the rigidity of the second portion and thereby reducing damage to the second portion when the engaging portion is separated from the second portion.

[0012] (Clause 2) Another aspect of the present invention provides an absorbent article for pets that is worn by wrapping it around the waist of a pet. This absorbent article for pets has a horizontally elongated shape having a longitudinal direction and a lateral direction, and comprises a main body portion including a top sheet arranged on the skin-facing side, a back sheet arranged on the non-skin-facing side, and an absorbent body arranged between the top sheet and the back sheet, and when the main body portion is divided into three equal regions in the longitudinal direction, the regions are defined as a first portion, a central portion, and a second portion in that order from one side in the longitudinal direction, and an engaging portion is provided in the first portion of the main body portion for engaging the first portion with the second portion, the main body portion including a compressed region formed in at least one of the top sheet and the back sheet and having one or more compressed portions recessed in the thickness direction of the main body portion, and the proportion of the area of ​​the one or more compressed portions formed in the second portion to the area of ​​the second portion is equal to or greater than the proportion of the area of ​​the one or more compressed portions formed in the first portion to the area of ​​the first portion.

[0013] In the pet absorbent article according to the above aspect, the compressed portions formed in the second portion account for a relatively large proportion of the area of ​​the second portion out of the one or more compressed portions, thereby increasing the rigidity of the second portion and thereby reducing damage to the second portion when the engaging portion is separated from the second portion.

[0014] (Clause 3) In the absorbent article for pets described in clause 1 or 2, the one or more compressed portions may be formed only in the second portion of the first and second portions. In this case, the rigidity of the second portion can be increased.

[0015] (Clause 4) In the absorbent article for pets described in any one of clauses 1 to 3, at least a portion of the top sheet may be compressed together with the back sheet in the compressed region. By compressing at least a portion of the top sheet together with the back sheet, the top sheet and the back sheet are mechanically joined, thereby making it possible to prevent the top sheet and the back sheet from peeling off from each other.

[0016] (Clause 5) In the absorbent article for pets according to any one of clauses 1 to 4, at least a portion of one or more compressed portions may be open in the top sheet and the back sheet. In this case, the breathability of the absorbent article for pets is improved. Therefore, it is possible to prevent the deterioration of the feel of the absorbent article for pets due to stuffiness.

[0017] (Clause 6) In the absorbent article for pets described in any one of clauses 1 to 5, the maximum width in the lateral direction of the compressed region may be equal to or greater than the maximum width in the lateral direction of the engagement portion. In this case, the compressed region is relatively wide in the lateral direction, allowing the entire engagement portion to engage with the highly rigid compressed region. This more reliably prevents damage to the second portion when the engagement portion is peeled off from the second portion.

[0018] (Clause 7) In the absorbent article for pets according to any one of clauses 1 to 6, the compressed regions may be formed in a position that does not overlap the absorbent body when viewed in the thickness direction of the main body. In this case, the stiffness of the absorbent body is prevented from increasing due to compression of the absorbent body, and the flexibility of the absorbent body can be maintained. As a result, deterioration in the feel of the absorbent article for pets can be suppressed.

[0019] (Clause 8) In the absorbent article for pets described in any one of clauses 1 to 6, the compressed regions may be formed in a position overlapping the absorbent body when viewed in the thickness direction of the main body, and at least a portion of the absorbent body may be compressed together with at least one of the topsheet and the backsheet. By compressing at least a portion of the absorbent body, urine is more easily drawn into the absorbent body along the compressed regions, improving urine diffusion. This can prevent deterioration of the feel of the absorbent body due to urine absorption. Furthermore, the increased rigidity of the absorbent body can prevent sagging of the absorbent body after absorbing urine.

[0020] (Clause 9) In the absorbent article for pets described in any one of clauses 1 to 6, when viewed in the thickness direction of the main body, the compressed region is formed in a position overlapping the absorbent body, and one or more compressed portions are formed on at least one of the top sheet and back sheet, and may not be formed on the absorbent body. In this case, the rigidity of the absorbent body is prevented from increasing due to compression of the absorbent body, and the flexibility of the absorbent body can be maintained. Furthermore, after forming compressed portions on at least one of the top sheet and back sheet, pet absorbent articles can be manufactured using the top sheet, back sheet, and absorbent body.

[0021] (Clause 10) In the absorbent article for pets described in any one of clauses 1 to 9, the second portion includes a first region and a second region located closer to the centerline of the main body portion in the longitudinal direction than the first region, and the density of the one or more compressed portions formed in the first region may be greater than the density of the one or more compressed portions formed in the second region. In this case, the rigidity of the first region, where the density of the one or more compressed portions is higher, will be higher, and the engaging force of the engaging portion with the first region will be relatively lower. This will allow the user to easily peel off the engaging portion engaged with the first region by pinching it with their fingers.

[0022] (Clause 11) In the absorbent article for pets described in any one of clauses 1 to 9, the second portion includes a first region and a second region located closer to the longitudinal centerline of the main body portion than the first region, and the density of the one or more compressed portions formed in the second region may be greater than the density of the one or more compressed portions formed in the first region. In this case, the rigidity of the second region, where the density of the one or more compressed portions is higher, is increased, and the engaging force of the engaging portion with the second region is relatively reduced. This allows the user to easily peel off the engaging portion engaged with the second region by pinching it with their fingers.

[0023] (Clause 12) In the absorbent article for pets described in any one of clauses 1 to 11, the second portion may include a third region and a fourth region located closer to the centerline of the main body portion in the short direction than the third region, and the density of the one or more compressed portions formed in the third region may be greater than the density of the one or more compressed portions formed in the fourth region. In this case, the rigidity of the third region, where the density of the one or more compressed portions is higher, will be higher, and the engaging force of the engaging portion with the third region will be relatively lower. This will allow the user to easily peel off the engaging portion engaged with the third region by pinching it with their fingers.

[0024] (Clause 13) In the absorbent article for pets described in any one of clauses 1 to 12, the compressed region may be formed in a position overlapping the engagement portion when viewed in the thickness direction of the main body portion, and at least a portion of the engagement portion may be compressed. In this case, the engagement force of the portion of the engagement portion where the compressed portion is formed with respect to the second portion is reduced, making it easier to peel the engagement portion from the second portion. This can further prevent damage to the second portion of the main body portion.

[0025] (Clause 14) In the absorbent article for pets described in any one of clauses 1 to 13, one or more compressed portions may include linear grooves recessed from one side of the top sheet or the back sheet to the other side. In this case, tearing of the main body portion can be effectively prevented when the engaging portion is peeled off from the second portion and a pulling force is applied in an in-plane direction to the top sheet or the back sheet.

[0026] (Clause 15) In the absorbent article for pets according to any one of clauses 1 to 14, at least one of the top sheet and the back sheet may be made of an air-through nonwoven fabric. In this case, the engaging portion can be directly engaged with at least one of the top sheet and the back sheet without providing a separate member. In addition, urine is less likely to remain on the air-through nonwoven fabric, which can prevent deterioration of the feel against the skin.

[0027] (Clause 16) The absorbent article for pets according to any one of clauses 1 to 15 may further include a target portion provided in the second portion and engaging with the engagement portion, and at least a portion of the compression region may be located adjacent to the target portion. By locating the compression region adjacent to the target portion, the rigidity of the portion of the second portion surrounding the target portion is increased, and therefore, when the engagement portion engages with the portion surrounding the target portion and the engagement portion is peeled off from the second portion, damage to the portion surrounding the target portion can be suppressed.

[0028] (Clause 17) The absorbent article for pets described in any one of clauses 1 to 16 further includes a pair of leak-preventing gathers spaced apart in the short direction and capable of standing upright relative to the main body portion, each of the pair of leak-preventing gathers including a side sheet and a first elastic member arranged along the inner edge of the side sheet in the short direction, and the compressed region may be formed in a position overlapping the side sheet when viewed in the thickness direction of the main body portion, and the side sheet may be compressed together with the main body portion. By compressing the side sheet together with the main body portion, the side sheet and the main body portion are mechanically bonded together, thereby preventing peeling between the side sheet and the main body portion. This reduces the amount of hot melt adhesive used to bond the side sheet and the main body portion, thereby preventing the hot melt adhesive from seeping out. This prevents the deterioration of the feel of the product against the skin caused by the hot melt adhesive seeping out.

[0029] (Clause 18) In the absorbent article for pets described in Clause 17, the first elastic member may include an effective region joined to the side sheet, and the side sheet may be compressed at a position that does not overlap the effective region of the first elastic member when viewed in the thickness direction. The effective region of the first elastic member is joined to the side sheet, so it stretches and contracts together with the side sheet. By compressing the side sheet at a position that does not overlap the effective region, the stretching of the first elastic member is prevented from being hindered.

[0030] (Clause 19) The absorbent article for pets described in clause 17 or 18 may further include a second elastic member disposed outward of the first elastic member in the short direction and including an effective area joined to the main body, and the compressed area may be disposed in a position that does not overlap with the effective area of ​​the second elastic member. In this case, the stretching of the second elastic member is not hindered.

[0031] [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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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 located at one end in the short direction X and a rear edge 4 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 on the front legs of the pet, and the rear edge 4 is located on the rear legs of the pet. In the following description, the direction from the rear edge 4 to the front edge 3 may be referred to as the "front side," and the direction from the front edge 3 to the rear edge 4 may be referred to as the "rear side." The main body 2 also has a first side edge 5 located at one end in the long direction Y and a second side edge 6 located at the other end in the long direction Y.

[0036] 2, when the main body 2 is divided into three equal regions in the longitudinal direction Y, the regions are designated as a first portion 2A, a central portion 2C, and a second portion 2B, in that order from one side in the longitudinal direction Y, the first portion 2A is disposed on one side in the longitudinal direction Y (the side of the first side edge 5), the second portion 2B is disposed on the other side in the longitudinal direction Y (the side of the second side edge 6), and the central portion 2C is disposed between the first portion 2A and the second portion 2B. The central portion 2C is disposed so as to straddle the center line P1 of the main body 2 in the longitudinal direction Y.

[0037] The main body 2 has a third portion 2D 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 fourth portion 2E 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 third portion 2D is the region between the center line P1 and the first side edge 5, and the fourth portion 2E is the region between the center line P1 and the second side edge 6. The third portion 2D includes the first portion 2A, and the fourth portion 2E includes the second portion 2B.

[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 the 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 joined to the backsheet 20 and the absorbent body 30 with, for example, a hot melt adhesive.

[0039] The back sheet 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 back sheet 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 to 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. The back film 21 is joined to the back nonwoven fabric 22 and the absorbent body 30 with, for example, a hot melt adhesive.

[0040] Examples of nonwoven fabrics constituting the topsheet 10 and the backing nonwoven fabric 22 include air-through nonwoven fabrics, spunbond nonwoven fabrics, and point-bond nonwoven fabrics. In particular, when at least one of the topsheet 10 and the backing nonwoven fabric 22 is made of air-through nonwoven fabric, urine is less likely to remain on the air-through nonwoven fabric, thereby preventing deterioration in texture. Air-through nonwoven fabrics are classified as thermal-bond nonwoven fabrics. Air-through nonwoven fabrics are produced, for example, by heat-treating a web of composite fibers composed of at least two thermoplastic resins with different melting points. Known methods for heat-treating a web include, for example, using a heat treatment device (e.g., a hot air penetration type heat treatment machine or a hot air blowing type heat treatment machine) equipped with a transport support that supports and transports the web to thermally bond the fibers together, thereby forming the fibers into a nonwoven fabric. The fineness of the composite fiber is, for example, 0.8 to 6.0 dtex. The basis weight of the air-through nonwoven fabric is, for example, 15 to 45 g / m. ２ The thickness of the air-through nonwoven fabric is, for example, 0.2 to 2 mm. The fiber density of the air-through nonwoven fabric is, for example, 20 to 100 fibers / mm ２ The fiber density is the number of fibers per unit area in the cross section of the air-through nonwoven fabric.

[0041] 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.

[0042] 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.

[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 leakage-preventing gathers 41 include a side sheet 42 and a first elastic member 43 arranged along the inner edge 42a of the side sheet 42 in the short direction X. The rear leakage-preventing gathers 51 include a side sheet 52 and a first elastic member 53 arranged along the inner edge 52a of the side sheet 52 in the short direction X. Each of the pair of side sheets 42, 52 is made of a water-repellent or hydrophobic nonwoven fabric. For example, the side sheets 42, 52 are made of a spunlace nonwoven fabric, a spunbond nonwoven fabric, a thermalbond nonwoven fabric, a meltblown nonwoven fabric, an SMS nonwoven fabric, a needle-punched nonwoven fabric, an air-through nonwoven fabric, or the like.

[0047] FIG. 5 is a schematic diagram showing the configuration of the leakage-preventing gathers 40. For ease of explanation, the areas of the pair of side sheets 42, 52 joined to the topsheet 10 are shaded in FIG. 5 . As shown in FIG. 5 , the side sheet 42 of the front leakage-preventing gathers 41 includes a horizontal fastening portion 44, a first vertical fastening portion 45, a second vertical fastening portion 46, and a standing portion 47. The horizontal fastening portion 44, the first vertical fastening portion 45, and the second vertical fastening portion 46 are areas of the side sheet 42 joined to the topsheet 10. The standing portion 47 is an area of ​​the side sheet 42 not joined to the topsheet 10. A standing line 44a is formed at the boundary between the horizontal fastening portion 44 and the standing portion 47, which serves as a supporting point for the standing portion 47 in the short direction X. A standing line 45a is formed at the boundary between the first vertical fastening portion 45 and the standing portion 47, which serves as a supporting point for the standing portion 47 in the longitudinal direction Y. An upright line 46 a is formed at the boundary between the second vertical fixing portion 46 and the upright portion 47 , and serves as an upright fulcrum for the upright portion 47 in the longitudinal direction Y.

[0048] The lateral fixing portion 44 is disposed on one side of the absorbent body 30 in the short direction X (the front edge 3 side), and extends along the longitudinal direction Y. Note that a portion of the side sheet 42 disposed outside the lateral fixing portion 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 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). The first vertical fixing portion 45 and the second vertical fixing portion 46 partially overlap the absorbent body 30 when viewed in the thickness direction Z, and are disposed spaced apart inward in the short direction X from the lateral fixing portion 44. That is, the region of the side sheet 42 between the lateral fixing portion 44 and the first vertical fixing portion 45 and the region between the lateral fixing portion 44 and the second vertical fixing portion 46 are not bonded to the topsheet 10. Note that these regions may also be bonded to the topsheet 10 with a hot melt adhesive.

[0050] The standing line 44a is disposed between the center line P2 in the lateral direction X of the main body portion 2 and the front edge 3, and extends in the longitudinal direction Y. For example, the standing line 44a is disposed between the front edge of the absorber 30 and the front edge 3. The standing line 44a serves as a supporting point for the standing portion 47 in the lateral direction X. The standing line 44a may partially overlap the absorber 30 when viewed from the thickness direction Z.

[0051] The standing line 45a 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 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 supporting point for the 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.

[0052] The standing line 46a is disposed between the center line P1 and the second side edge 6 in the longitudinal direction Y of the main body 2, and extends in the short direction X. For example, the 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 supporting point for the 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.

[0053] As described above, the first region 42A of the side sheet 42, which is located closer to the first side edge 5 than the standing line 45a, is joined to the top sheet 10 in a state of being folded inward in the short direction X. In the embodiment shown in Figure 5, the first region 42A includes a first vertical fixing portion 45. Similarly, the second region 42B of the side sheet 42, which is located closer to the second side edge 6 than the standing line 46a, is joined to the top sheet 10 in a state of being folded inward in the short direction X. In the embodiment shown in Figure 5, the second region 42B includes a second vertical fixing portion 46. The first region 42A and the second region 42B of the side sheet 42 are fixed to the top sheet 10 and are non-standing regions that do not stand up.

[0054] In contrast, the standing portion 47 is a standing region that is located between the first region 42A and the second region 42B on the inside of the standing line 44a in the short-side direction X. The standing portion 47 can stand along the 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 side sheet 42 are joined to the main body 2, the standing portion 47 is folded inward in the short-side direction X in the unfolded state, as shown in FIG.

[0055] 4, a part of the inner portion of the side 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 side 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.

[0056] The first elastic members 43 include an effective region 43a joined to the side sheet 42. The effective region 43a occupies substantially the entire area of ​​the first elastic members 43, and is joined to the side sheet 42 with a hot melt adhesive while stretched in the longitudinal direction Y. As a result, when the effective region 43a of the first elastic members 43 contracts in the longitudinal direction Y, the standing portions 47 of the side sheet 42 contract in the longitudinal direction Y together with the first elastic members 43. As a result, the standing portions 47 stand along the standing lines 44a outside the lateral direction X of the absorbent body 30. The standing portions 47 of the front leakage prevention gathers 41 stand up, preventing pet urine from leaking forward along the surface of the topsheet 10.

[0057] In one embodiment, the first elastic members 43 may include ineffective regions that are not joined to the side sheets 42. The ineffective regions are regions that do not contribute to the standing ability of the standing portions 47. For example, both ends of the first elastic members 43 in the longitudinal direction Y may be ineffective regions. The ineffective regions may be located between the folded-back standing portions 47, or between the folded-back first vertical fixing portions 45 or second vertical fixing portions 46.

[0058] The side sheet 52 of the rear leakage preventing gathers 51 includes a horizontal fixing portion 54, a first vertical fixing portion 55, a second vertical fixing portion 56, and a standing portion 57. The horizontal fixing portion 54, the first vertical fixing portion 55, and the second vertical fixing portion 56 are regions of the side sheet 52 joined to the topsheet 10. The standing portion 57 is a region of the side sheet 52 not joined to the topsheet 10. A standing line 54a is formed at the boundary between the horizontal fixing portion 54 and the standing portion 57, serving as a standing fulcrum for the standing portion 57 in the short direction X. A standing line 55a is formed at the boundary between the first vertical fixing portion 55 and the standing portion 57, serving as a standing fulcrum for the standing portion 57 in the longitudinal direction Y. A standing line 56a is formed at the boundary between the second vertical fixing portion 56 and the standing portion 57, serving as a standing fulcrum for the standing portion 57 in the longitudinal direction Y.

[0059] The lateral fixing portion 54 is disposed on the other side in the short direction X (the rear edge 4 side) of the absorbent body 30, and extends along the longitudinal direction Y. Note that a portion of the side sheet 52 disposed outside the lateral fixing portion 54 in the short direction X may also be fixed to the topsheet 10.

[0060] 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 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). 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. The distance between the first vertical fixing portion 55 and the second vertical fixing portion 56 in the longitudinal direction Y is longer than the distance between the first vertical fixing portion 45 and the second vertical fixing portion 46 in the longitudinal direction Y. In other words, the width of the standing portion 57 in the longitudinal direction Y is greater than the width of the standing portion 47 in the longitudinal direction Y. Note that 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. The first vertical fixing portion 55 and the second vertical fixing portion 56 are disposed inward in the short direction X and spaced apart from the lateral fixing portion 54. That is, the region of the side sheet 52 between the horizontal fixing portion 54 and the first vertical fixing portion 55, and the region between the horizontal fixing portion 54 and the second vertical fixing portion 56 are not joined to the topsheet 10. These regions may also be joined to the topsheet 10 with a hot melt adhesive.

[0061] The standing line 54a 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 standing line 54a is disposed between the rear edge of the absorber 30 and the rear edge 4. The standing line 54a serves as a supporting point for the standing portion 57 in the lateral direction X. The standing line 54a may partially overlap the absorber 30 when viewed from the thickness direction Z.

[0062] The standing line 55a 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 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 supporting point for the 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.

[0063] The standing line 56a 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 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 supporting point for the 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.

[0064] As described above, the first region 52A of the side sheet 52, which is located closer to the first side edge 5 than the standing line 55a, is joined to the top sheet 10 in a state of being folded inward in the short direction X. In the embodiment shown in FIG. 5 , the first region 52A includes a first vertical fixing portion 55. Similarly, the second region 52B of the side sheet 52, which is located closer to the second side edge 6 than the standing line 56a, is joined to the top sheet 10 in a state of being folded inward in the short direction X. In the embodiment shown in FIG. 5 , the second region 52B includes a second vertical fixing portion 56. The first region 52A and the second region 52B of the side sheet 52 are fixed to the top sheet 10 and are non-standing regions that do not stand up.

[0065] In contrast, the standing portion 57 is a standing region that is located between the first region 52A and the second region 52B on the inside of the standing line 54a in the short-side direction X. The standing portion 57 can stand along the standing line 54a between the first region 52A and the second region 52B. The length of the standing portion 57 in the longitudinal direction Y is longer than the length of the standing portion 47 in the longitudinal direction Y. Note that, because the first region 52A and the second region 52B of the side sheet 52 are joined to the main body portion 2, the standing portion 57 is folded inward in the short-side direction X in the unfolded state, as shown in FIG. 4 .

[0066] 4, a part of the inner portion of the side sheet 52 in the short direction X is folded back toward the non-skin-facing side Z2, and a first elastic member 53 is disposed between the folded back side sheet 52. The first elastic member 53 is made of a stretchable material such as rubber or spandex that is contractible in the longitudinal direction Y.

[0067] The first elastic members 53 include an effective region 53a joined to the side sheet 52. The effective region 53a occupies substantially the entire area of ​​the first elastic members 53, and is joined to the side sheet 52 with a hot melt adhesive while stretched in the longitudinal direction Y. As a result, when the effective region 53a of the first elastic members 53 contracts in the longitudinal direction Y, the standing portions 57 of the side sheet 52 contract in the longitudinal direction Y together with the first elastic members 53. As a result, the standing portions 57 stand along the standing lines 54a outside the short direction X of the absorbent body 30. The standing portions 57 of the rear leakage-preventing gathers 51 stand up, preventing pet urine from leaking along the surface of the topsheet 10 to the rear.

[0068] In one embodiment, the first elastic members 53 may include ineffective regions that are not joined to the side sheets 52. The ineffective regions are regions that do not contribute to the standing ability of the standing portions 57. For example, both ends of the first elastic members 53 in the longitudinal direction Y may be ineffective regions. The ineffective regions may be located between the folded-back standing portions 57, or between the folded-back first vertical fixing portions 55 or second vertical fixing portions 56.

[0069] In one embodiment, the length L1 in the short direction X along the surface of the front leakage-preventing gathers 41 from the rising line 44a to the apex of the rising portion 47 is longer than the length L2 in the short direction X along the surface of the rear leakage-preventing gathers 51 from the rising line 54a to the apex of the rising portion 57. In other words, the maximum rising height of the front leakage-preventing gathers 41 relative to the main body portion 2 is higher than the maximum rising height of the rear leakage-preventing gathers 51 relative to the main body portion 2. As a result, when the pet absorbent article 1 is worn so that the front leakage-preventing gathers 41 are positioned toward the pet's head, the front leakage-preventing gathers 41 can block urine that is forcefully excreted by the pet, thereby effectively preventing urine leakage. Note that the length L2 of the rear leakage-preventing gathers 51 may be longer than the length L1 of the front leakage-preventing gathers 41. In this case, the rear leakage-preventing gathers 51 can block urine that flows rearward, thereby effectively preventing urine leakage.

[0070] The pet absorbent article 1 further includes a pair of second elastic members 61, 62 stretchable in the longitudinal direction Y, and a plurality of inner elastic members 63 stretchable in the longitudinal direction Y. The number of each of the second elastic members 61, 62 and the inner elastic members 63 may be any number equal to or greater than one. As shown in FIG. 4 , the second elastic members 61, 62 are disposed, for example, between the pair of leakage-preventing gathers 40 and the backsheet 20 (backsheet nonwoven fabric 22). The inner elastic member 63 is disposed between the topsheet 10 and the backsheet 20. The second elastic members 61, 62 and the inner elastic member 63 stretch to accommodate changes in the pet's body shape and posture in the longitudinal direction Y (e.g., when the pet twists its body). Each of the second elastic members 61, 62 and the inner elastic member 63 is made of a stretchable material, such as rubber, a stretchable nonwoven fabric, a stretchable film, or spandex.

[0071] The second elastic member 61 is provided outside the standing line 44a in the short direction X and extends along the front edge 3. The second elastic member 61 is disposed between the front leakage preventing gathers 41 and the back sheet 20. The second elastic member 61 includes an effective region 61a that is joined to the main body portion 2 with a hot melt adhesive in a state stretched in the longitudinal direction Y. The effective region 61a occupies substantially the entire area of ​​the second elastic member 61, and is joined to the side sheet 42 of the front leakage preventing gathers 41 and the back nonwoven fabric 22. The second elastic member 61 imparts stretchability to the main body portion 2.

[0072] The second elastic member 62 is provided outside the standing line 54a in the short direction X and extends along the rear edge 4. The second elastic member 62 is disposed between the rear leakage preventing gathers 51 and the backsheet 20. The second elastic member 62 includes an effective region 62a that is joined to the main body portion 2 with a hot melt adhesive in a state stretched in the longitudinal direction Y. The effective region 62a occupies substantially the entire area of ​​the second elastic member 62, and is joined to the side sheet 52 of the rear leakage preventing gathers 51 and the back nonwoven fabric 22. The second elastic member 62 imparts stretchability to the main body portion 2.

[0073] Each of the second elastic members 61, 62 may include an ineffective region that is not joined to the main body portion 2. The ineffective region is a region that does not contribute to the stretchability of the main body portion 2. For example, both ends of each of the second elastic members 61, 62 in the longitudinal direction Y may be ineffective regions.

[0074] As shown in Fig. 5, the inner elastic member 63 is disposed between the upright line 44a and the upright line 54a in the short direction X, imparting stretchability to the main body portion 2. In one embodiment, a plurality of inner elastic members 63 are provided at a first end portion 7 (Fig. 2) 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 (described below). 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.

[0075] 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.

[0076] 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.

[0077] Fig. 6 is an enlarged plan view of a portion B of the main body portion 2 shown in Fig. 2. Fig. 7 is a cross-sectional view of the absorbent article for pet 1 taken along line CC in Fig. 2. As shown in Figs. 2, 3, 6 and 7, the main body portion 2 includes a compressed region 81 having a plurality of compressed portions 80 recessed in the thickness direction Z of the main body portion 2. Each of the plurality of compressed portions 80 is a region of the main body portion 2 that has been made denser than other portions by embossing or the like. The compressed region 81 is a region in which a plurality of compressed portions 80 are formed regularly or at substantially regular intervals.

[0078] Each of the multiple compressed portions 80 has a planar shape, for example, a circular or elliptical shape, and is recessed in the thickness direction Z of the main body portion 2. Each compressed portion 80 may have any shape, such as a triangle, square, or diamond. The multiple compressed portions 80 can be formed, for example, by compressing from the thickness direction Z using a roller having multiple protrusions that are the inverse shapes of the compressed portions 80. In one embodiment, the multiple compressed portions 80 may be formed on the top sheet 10 and the back sheet 20 by compressing the main body portion 2 with the top sheet 10 and the back sheet 20 stacked together using a roller. That is, in the compressed region 81, at least a portion of the top sheet 10 is compressed together with the back sheet 20. By compressing the top sheet 10 together with the back sheet 20, the top sheet 10 and the back sheet 20 are mechanically bonded together, thereby preventing the top sheet 10 and the back sheet 20 from peeling off.

[0079] In one embodiment, the compressed region 81 is located in the fourth portion 2E. More specifically, the compressed region 81 is located in the second end portion 8 of the second portion 2B. That is, the multiple compressed portions 80 are not formed in the first portion 2A or the central portion 2C, but are formed only in the second portion 2B. In one embodiment, the compressed region 81 may be formed only in a portion of the second end portion 8 on the second side edge 6 side. By forming multiple compressed portions 80 in the second portion 2B of the main body 2, the rigidity of the second portion 2B is increased. Note that the compressed region 81 may include at least one compressed portion 80.

[0080] As shown in Fig. 6, the multiple compressed portions 80 are formed intermittently along multiple first virtual lines K1 extending parallel to the diagonal direction D1 and multiple second virtual lines K2 extending parallel to the diagonal direction D2. The diagonal directions D1 and D2 are, for example, directions that intersect with the short-side direction X and the long-side direction Y. In other words, the multiple compressed portions 80 are arranged in a lattice pattern. Note that the multiple compressed portions 80 only need to be arranged two-dimensionally, and do not necessarily have to be arranged along the diagonal directions D1 and D2.

[0081] As described above, the proportion of the area of ​​the compressed portions 80 formed in the second portion 2B among the plurality of compressed portions 80 to the area of ​​the second portion 2B is equal to or greater than the proportion of the area of ​​the compressed portions 80 formed in the first portion 2A among the plurality of compressed portions 80 to the area of ​​the first portion 2A. The area of ​​the plurality of compressed portions 80 refers to the total area of ​​the plurality of compressed portions 80. The proportion of the area of ​​the plurality of compressed portions 80 to the area of ​​the first portion 2A or the second portion 2B can be determined by using any magnifying observation means such as a magnifying glass or microscope to measure the area of ​​each compressed portion 80 and the number of the plurality of compressed portions 80 as viewed from the thickness direction Z, calculating the total area of ​​the plurality of compressed portions 80, and then dividing this by the separately measured area of ​​the first portion 2A or the second portion 2B and multiplying by 100. In the embodiment shown in Figure 2, since no compressed portion 80 is formed in the first portion 2A, the proportion of the area of ​​the compressed portion 80 formed in the first portion 2A to the area of ​​the first portion 2A is 0%.

[0082] As shown in Figure 2, when viewed from the thickness direction Z of the main body 2, the compressed regions 81 are formed in positions that do not overlap the absorbent body 30. In other words, multiple compressed portions 80 are not formed in the absorbent body 30. By not forming multiple compressed portions 80 in the absorbent body 30, it is possible to prevent an increase in the rigidity of the absorbent body 30. Therefore, it is possible to maintain the flexibility of the absorbent body 30, and as a result, it is possible to prevent a deterioration in the feel against the skin.

[0083] In one embodiment, the compressed regions 81 may be formed in a position overlapping the side sheets 42, 52 as viewed in the thickness direction Z of the main body portion 2. For example, the compressed regions 81 are positioned in a position overlapping the portions of the side sheets 42, 52 on the second side edge 6 side as viewed in the thickness direction Z. Therefore, as shown in FIGS. 2 and 7 , the side sheets 42, 52 are compressed together with the main body portion 2. For example, by compressing the pet absorbent article 1 with a roller having convex portions while the topsheet 10, backsheet 20, and side sheets 42, 52 are stacked, multiple compressed regions 80 are formed in the side sheets 42, 52. By compressing the side sheets 42, 52 together with the main body portion 2, the side sheets 42, 52 are mechanically bonded to the main body portion 2, thereby reducing the amount of hot melt adhesive used to bond the side sheets 42, 52 to the main body portion 2. As a result, seepage of the hot melt adhesive can be suppressed, and deterioration of the feel of the material due to seepage of the hot melt adhesive can be suppressed.

[0084] The compression region 81 may be disposed at a position that does not overlap the effective region 43a of the first elastic member 43 and the effective region 53a of the first elastic member 53. Compressing the side sheets 42, 52 at a position that does not overlap the effective regions 43a, 53a prevents the expansion and contraction of the first elastic members 43, 53. As described above, when the first elastic members 43, 53 include ineffective regions, the ineffective regions do not contribute to the uprightness of the standing portions 47, 57, and therefore the compression region 81 may be formed at a position that overlaps the ineffective regions.

[0085] Furthermore, the compression region 81 may be disposed at a position that does not overlap the effective region 61a of the second elastic member 61 and the effective region 62a of the second elastic member 62. This prevents the compression region 81 from hindering the stretching of the second elastic members 61, 62. As described above, when the second elastic members 61, 62 include ineffective regions, the ineffective regions do not contribute to the stretching of the main body portion 2, and therefore the compression region 81 may be formed at a position that overlaps the ineffective regions.

[0086] Next, referring to FIG. 8 , a 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.

[0087] In the pet absorbent article 1, as described above, the plurality of compressed portions 80 are formed at the second end portion 8 of the second portion 2B, thereby increasing the rigidity of the second portion 2B, thereby making it possible to prevent damage to the second portion 2B when the engaging portion 70 is peeled off from the second portion 2B.

[0088] In particular, as shown in Fig. 3, the compression region 81 is disposed adjacent to the target portion 71. For example, in the embodiment shown in Fig. 3, a portion of the compression region 81 is disposed in the region between the target portion 71 and the second side edge 6. This increases the rigidity of that region of the second portion 2B, and therefore prevents damage to that region of the second portion 2B when the engagement portion 70 engages with that region and is peeled off from the second portion 2B when the pet absorbent article 1 is removed from the pet. Note that at least a portion of the target portion 71 may be compressed together with the main body portion 2.

[0089] As shown in FIG. 2 , the maximum width W1 in the transverse direction X of the compressed region 81 may be equal to or greater than the maximum width W2 in the transverse direction X of the engagement portion 70. The maximum width W1 in the transverse direction X of the compressed region 81 refers to the distance in the transverse direction X between the position of the outermost compressed region 80 on one side of the transverse direction X among the multiple compressed regions 80 and the position of the outermost compressed region 80 on the other side of the transverse direction X among the multiple compressed regions 80. By making the maximum width W1 in the transverse direction X of the compressed region 81 greater than the maximum width W2 in the transverse direction X of the engagement portion 70, it becomes easier to engage the engagement portion 70 with the compressed region 81. This more reliably prevents damage to the second portion 2B when the engagement portion 70 is peeled off from the second portion 2B.

[0090] [Modifications] Fig. 9 is an enlarged plan view showing a portion of a pet absorbent article 1A according to a first modification. In the embodiment shown in Fig. 6, the plurality of compressed portions 80 are substantially uniformly arranged within the compressed region 81, but pet absorbent article 1A differs from pet absorbent article 1 in that the distribution of the plurality of compressed portions 80 is not uniform within the compressed region 81.

[0091] 9, the second portion 2B of the pet absorbent article 1A includes a first region 81a and a second region 81b that is positioned closer to the center line P1 in the longitudinal direction Y of the main body 2 than the first region 81a. The first region 81a and the second region 81b are part of the compressed region 81, and the first region 81a is positioned closer to the second side edge 6 than the second region 81b.

[0092] Of the multiple compressed portions 80, the density of the compressed portions 80 formed in the second region 81b is greater than the density of the compressed portions 80 formed in the first region 81a. Note that the density of the compressed portions 80 refers to the total area of ​​one or more compressed portions 80 per unit area. For example, as shown in Fig. 9, the distance between adjacent compressed portions 80 formed in the first region 81a is wider than the distance between adjacent compressed portions 80 formed in the second region 81b.

[0093] As shown in Figure 8, when the engagement portion 70 is provided on the topsheet 10, when the first portion 2A is engaged with the second portion 2B, the first portion 2A is positioned closer to the non-skin-facing side Z2 than the second portion 2B. In this case, when removing the pet absorbent article 1A from the pet, the user peels the engagement portion 70 from the second portion 2B in the order of the second region 81b and then the first region 81a. At this time, because the density of the compressed portions 80 in the second region 81b is relatively high, the engagement force of the engagement portion 70 with the second region 81b is relatively low. Therefore, the engagement portion 70 can be easily peeled from the second portion 2B in the order of the second region 81b and then the first region 81a. This prevents damage to the second portion 2B when peeling the engagement portion 70 from the second portion 2B.

[0094] Fig. 10 is a plan view of a pet absorbent article 1B according to a second modification, as viewed from the skin-facing side Z1. Fig. 11 is a plan view showing an enlarged portion of the pet absorbent article 1B according to the second modification. In the embodiment shown in Fig. 2, the engagement portion 70 is provided on the surface of the topsheet 10, and the target portion 71 is provided on the outer surface of the backsheet 20. However, the pet absorbent article 1B differs from the pet absorbent article 1 in that the engagement portion 70 is provided on the outer surface of the backsheet 20, and the target portion 71 is not provided. When the pet absorbent article 1B is worn, the engagement portion 70 directly engages with the surface of the topsheet 10. Note that the engagement portion 70 may engage with the topsheet 10 via a target portion provided on the topsheet 10. The engagement portion 70 may 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 engage with each other.

[0095] As shown in Fig. 11 , the second portion 2B of the pet absorbent article 1B includes a first region 81a and a second region 81b that is positioned closer to the center line P1 in the longitudinal direction Y of the main body portion 2 than the first region 81a. In the pet absorbent article 1B, the density of the compressed portions 80 formed in the first region 81a is greater than the density of the compressed portions 80 formed in the second region 81b. For example, as shown in Fig. 11 , the distance between adjacent compressed portions 80 formed in the first region 81a is narrower than the distance between adjacent compressed portions 80 formed in the second region 81b.

[0096] If the engaging portion 70 is provided on the backsheet 20, when the first portion 2A is engaged with the second portion 2B, the second portion 2B is positioned closer to the non-skin-facing side Z2 than the first portion 2A. In this case, when removing the pet absorbent article 1B from the pet, the user peels the second portion 2B from the engaging portion 70 in the order of the first region 81a and then the second region 81b. Because the density of the compressed portions 80 in the first region 81a is relatively high, the engaging force of the engaging portion 70 with respect to the first region 81a is relatively low. Therefore, the second portion 2B can be easily peeled from the engaging portion 70 in the order of the first region 81a and then the second region 81b. This further reduces damage to the second portion 2B when peeling the second portion 2B from the engaging portion 70.

[0097] Fig. 12 is an enlarged plan view showing a portion of a pet absorbent article 1C according to a third modification. In the embodiment shown in Fig. 2, the plurality of compressed portions 80 are substantially uniformly arranged within the compressed region 81, but pet absorbent article 1C differs from pet absorbent article 1 in that the distribution of the plurality of compressed portions 80 is not uniform within the compressed region 81.

[0098] The second portion 2B includes a pair of third regions 81c, 81d and a fourth region 81e that is positioned closer to the center line P2 side of the pair of third regions 81c, 81d in the short-side direction X of the main body 2. The pair of third regions 81c, 81d and the fourth region 81e are part of the compressed region 81, and the fourth region 81e is positioned between the pair of third regions 81c, 81d.

[0099] The density of the compressed portions 80 formed in the pair of third regions 81c, 81d among the plurality of compressed portions 80 is greater than the density of the compressed portions 80 formed in the fourth region 81e among the plurality of compressed portions 80. For example, as shown in Fig. 12, the distance between adjacent compressed portions 80 formed in the pair of third regions 81c, 81d is narrower than the distance between adjacent compressed portions 80 formed in the fourth region 81e. Note that the density of the compressed portions 80 formed in the third region 81c may be the same as the density of the compressed portions 80 formed in the third region 81d.

[0100] As described above, in the pet absorbent article 1C, the density of the compressed portions 80 formed in the pair of third regions 81c, 81d is relatively high, and therefore the engagement force of the engagement portion 70 with the pair of third regions 81c, 81d is relatively low. Therefore, the engagement portion 70 can be easily peeled from the second portion 2B in the order of one of the pair of third regions 81c, 81d and then the fourth region 81e. Therefore, damage to the second portion 2B can be suppressed when the engagement portion 70 is peeled from the second portion 2B.

[0101] In the third modified example, the compression portions 80 are provided in both of the pair of third regions 81c, 81d, but it is also possible that the compression portions 80 are provided in one of the pair of third regions 81c, 81d and the other of the pair of third regions 81c, 81d is not provided with a compression portion 80. Even in this case, the engaging portion 70 can be easily peeled off from the second portion 2B in the order of the region of the pair of third regions 81c, 81d where the compression portions 80 are provided and the fourth region 81e.

[0102] Fig. 13 is an enlarged plan view showing a portion of a pet absorbent article 1D according to a fourth modification. While the pet absorbent articles 1, 1A, 1B, and 1C each have a plurality of compressed portions 80 distributed two-dimensionally in the main body portion 2, the pet absorbent article 1D has linear compressed portions 80 formed in the main body portion 2. These compressed portions 80 are linear grooves recessed from one side of the topsheet 10 and the backsheet 20 to the other. As shown in Fig. 13, the compressed portions 80 of the pet absorbent article 1D are formed in a lattice pattern and extend linearly along a plurality of first imaginary lines K1 and a plurality of second imaginary lines K2. Forming the compressed portions 80 in a lattice pattern effectively prevents the main body portion 2 from tearing when the engaging portions 70 are peeled off from the second portion 2B and a force pulling the topsheet 10 or the backsheet 20 in an in-plane direction is applied.

[0103] 14 is a plan view of a pet absorbent article 1E according to a fifth modification, as viewed from the skin-facing side Z1. In the pet absorbent articles 1, 1A, 1B, 1C, and 1D, the compressed portions 80 are formed at the second end 8 of the second portion 2B, and are not formed in the first portion 2A or the central portion 2C, but in the pet absorbent article 1E, the compressed portions 80 are formed throughout the entire main body 2. That is, in the pet absorbent article 1E, the compressed portions 80 are also formed in the first portion 2A and the central portion 2C.

[0104] As shown in FIG. 14 , in the pet absorbent article 1E, the compressed portions 80 are formed at positions overlapping the absorber 30 when viewed from the thickness direction Z of the main body 2. At least a portion of the absorber 30 may be compressed together with the topsheet 10. At least a portion of the absorber 30 may be compressed together with the backsheet 20. Compressing at least a portion of the absorber 30 allows urine to flow along the compressed portions 80 formed in the absorber 30, thereby improving urine diffusion. This prevents deterioration of the feel of the absorber 30 due to urine absorption. Furthermore, compressing at least a portion of the absorber 30 increases the rigidity of the absorber 30, thereby preventing the absorber 30 from sagging due to the weight of the urine when urine is absorbed by the absorber 30.

[0105] When viewed from the thickness direction Z of the main body 2, the compressed regions 81 may be formed in a position overlapping the absorbent body 30, and the compressed parts 80 may be formed in at least one of the topsheet 10 and the backsheet 20, and not necessarily in the absorbent body 30. Not forming the compressed parts 80 in the absorbent body 30 prevents the rigidity of the absorbent body 30 from increasing due to compression of the absorbent body 30, and allows the flexibility of the absorbent body 30 to be maintained. Furthermore, after forming the compressed parts 80 in at least one of the topsheet 10 and the backsheet 20, the pet absorbent article 1E can be manufactured using the topsheet 10, the backsheet 20, and the absorbent body 30.

[0106] In one embodiment, as shown in FIG. 14 , the compressed region 81 may be formed at a position overlapping the engaging portion 70 when viewed from the thickness direction Z of the main body portion 2. That is, at least a portion of the engaging portion 70 is compressed. When the engaging portion 70 is compressed, some of the hooks of the engaging portion 70 are crushed, reducing the engaging force of the engaging portion 70, making it easier to peel the engaging portion 70 from the second portion 2B. This further reduces damage to the second portion 2B. Note that at least a portion of the engaging portion 70 may be compressed together with the topsheet 10. In this case, the topsheet 10 and the engaging portion 70 are mechanically bonded by the compressed region 80, thereby reducing the amount of hot melt adhesive used. As a result, seepage of adhesive from the bonded portion between the topsheet 10 and the engaging portion 70 can be suppressed.

[0107] 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.

[0108] For example, in each of the above-described pet absorbent articles 1, 1A to 1E, at least a portion of the compressed portion 80 may be open in the top sheet 10 and the back sheet 20. In other words, at least a portion of the compressed portion 80 may be a through-hole that penetrates the main body 2 along the thickness direction Z. In this case, the breathability of the pet absorbent articles 1, 1A to 1E is improved. Therefore, it is possible to suppress a decrease in the feel of the pet absorbent articles 1, 1A to 1E due to stuffiness.

[0109] In each of the above-described pet absorbent articles 1, 1A to 1E, the compressed portions 80 may be formed on only one of the top sheet 10 and the back sheet 20. The above-described various embodiments and modified examples can be combined to the extent that no contradictions are present.
