FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1. FIG. 3 is a plan view of the extending member, where (a) shows an embodiment and (b) and (c) show modified examples. FIG. 4 is a cross-sectional view of the extending member, where (a) shows a cross-section taken along line IVa-IVa of FIG. 3(a) and (b) shows a cross-section taken along line IVb-IVb of FIG. 3(a). Note that in FIGS. 2 and 4, the cross-section of the absorbent article for pets is schematically shown. Further, each figure does not define the size relationship of the component members of the absorbent article for pets, and the dimensions of each component member can be appropriately selected from a wide range according to the use of the absorbent article for pets, the type of pet to be used, and the like.

[0018] <Absorbent article for pets> The absorbent article 10 for pets according to an embodiment of the present invention is for wearing on a pet (for example, a dog, a cat, etc.), and is particularly preferably used for male pets.

[0019] As shown in FIGS. 1 and 2, the absorbent article 10 for pets is worn around the pet's torso, and includes an absorbent main body 11 that mainly absorbs body fluids, and left and right leg attachment portions 12 that can be attached to the left and right hind legs of the pet.

[0020] (Absorbent main body) As shown in FIGS. 1 and 2, the absorbent main body 11 includes a liquid-permeable topsheet 13 on the skin side, a liquid-impermeable backsheet 14 on the non-skin side, an absorber 15 disposed between the topsheet 13 and the backsheet 14, and front and rear three-dimensional gathers 16 provided on both sides in the width direction of the skin side surface of the topsheet 13 and extending in the longitudinal direction, and a main body fastening portion 17 provided at one end in the longitudinal direction. The absorbent main body 11 is formed in a long shape in a predetermined direction (X direction) so as to be wound around the pet's torso. In this embodiment, the shape of the absorbent main body 11 is substantially rectangular, but it is not limited thereto, and the shape of the absorbent main body 11 may be at least a belt shape that can be worn around the pet's torso.

[0021] The longitudinal dimension L of the absorbent main body 11 is preferably 300 mm or more and 570 mm or less. The width dimension W of the absorbent main body 11 is preferably 180 mm or more and 350 mm or less. By setting the dimensions of the absorbent main body 11 within the above ranges, an absorbent article 10 for pets having a size suitable for pets such as dogs and cats can be obtained. Further, by setting the dimensions of the absorbent main body 11 within the above ranges, an absorbent article 10 for pets that can also accommodate pets with a large (thick) torso circumference and a short torso length (for example, a dog) can be obtained.

[0022] (Topsheet) The topsheet 13 may be formed from a base material having liquid permeability such that body fluid moves to the absorber 15. As an example of the base material of the topsheet 13, for example, a hydrophilic sheet, a composite nonwoven fabric which is a laminate of the same or different hydrophilic sheets, a perforated film such as a perforated polyethylene film, a polyethylene foam, a foamed film such as a urethane foam, etc. may be mentioned. Examples of the hydrophilic sheet include an air-through nonwoven fabric, a thermal bond nonwoven fabric, a spunlace nonwoven fabric, a spunbond nonwoven fabric, etc. which are made using synthetic fibers made of synthetic resins such as polypropylene and polyethylene, regenerated fibers such as rayon, and natural fibers such as cotton. Among these, nonwoven fabrics are preferred, and air-through nonwoven fabrics or spunbond nonwoven fabrics are more preferred from the viewpoint of texture.

[0023] The topsheet 13 may be embossed or perforated on the surface in order to improve liquid permeability. As a method for performing these embossing and perforating processes, known methods can be implemented without limitation. Further, in order to reduce irritation to the skin, the topsheet 13 may contain a lotion, an antioxidant, an anti-inflammatory component, a pH adjuster, an antibacterial agent, a moisturizing agent, etc. The shape of the topsheet 13 is not particularly limited, and as long as it is a shape that covers the absorber 15 in order to guide body fluid to the absorber 15 without leakage.

[0024] (Backsheet) As shown in FIG. 2, the backsheet 14 has a resin film (film portion) 18 on the skin side having liquid impermeability so that the body fluid held by the absorber 15 does not leak to the non-skin side, and a nonwoven fabric (nonwoven fabric portion) 19 located on the non-skin side of the resin film 18, and is a composite sheet in which these are laminated. The nonwoven fabric 19 is located on the non-skin side surface of the backsheet 14. Although FIG. 2 shows the backsheet 14 in which two sheets of the resin film 18 and the nonwoven fabric 19 are laminated, it is not limited thereto. For example, the backsheet 14 may be a laminate of three or more sheets including the resin film 18 and the nonwoven fabric 19 located on the non-skin side surface.

[0025] Examples of the resin film 18 used for the backsheet 14 include polyester, polyvinyl alcohol, polyethylene, polypropylene, and a composite film of polyethylene and polypropylene.

[0026] The nonwoven fabric 19 used for the backsheet 14 is not particularly limited in its manufacturing method. Examples include spunbond nonwoven fabric, meltblown nonwoven fabric, a composite nonwoven fabric formed by laminating a plurality of the same type and / or different types of nonwoven fabrics such as spunbond nonwoven fabric / meltblown nonwoven fabric and spunbond nonwoven fabric / meltblown nonwoven fabric / spunbond nonwoven fabric, and composite materials thereof.

[0027] It is preferable to provide the backsheet 14 with air permeability in order to prevent stuffiness during wearing. To provide the backsheet 14 with air permeability, for example, a filler may be blended into the resin film 18 of the base material, or the backsheet 14 may be embossed. Calcium carbonate can be cited as the filler, and its blending method can be carried out without limitation using known methods. For example, a porous (air-permeable) resin film can be obtained by kneading a resin and a filler, molding the obtained kneaded product into a film shape, and removing the filler from the obtained film.

[0028] (Absorbent body) The absorbent body 15 is disposed between the topsheet 13 and the backsheet 14 and absorbs and holds the body fluid that has passed through the topsheet 13. The shape of the absorbent body 15 is not particularly limited, and examples include a rectangular shape and an oval shape.

[0029] Some absorbent bodies 15 contain, for example, absorbent fibers and a superabsorbent polymer as an absorbent base material.

[0030] (Absorbent fiber) The absorbent fiber is not particularly limited as long as it is generally used in absorbent articles such as sanitary napkins, paper diapers, urine pads, etc. Examples include fluff pulp, cotton, rayon, acetate, tissue, absorbent paper, hydrophilic non-woven fabric, etc. Among these, fluff pulp is preferred from the viewpoint of absorbency. Examples of fluff pulp include cotton-like defibered materials such as wood pulp (e.g., softwood kraft pulp (N-BKP) such as southern pine and Douglas fir), synthetic fibers, resin fibers, and non-wood pulp.

[0031] (Superabsorbent polymer) The superabsorbent polymer (hereinafter also referred to as "SAP") is not particularly limited as long as it can absorb body fluids and prevent backflow. Examples include polyacrylate salts, polyaspartate salts, (starch-acrylic acid) graft copolymers, (acrylic acid-vinyl alcohol) copolymers, (isobutylene-maleic anhydride) copolymers, and saponified products thereof. Among these, polyacrylate salts are preferred from the viewpoint of the absorption amount per unit weight, alkali metal polyacrylate salts are more preferred, and sodium polyacrylate is even more preferred. The superabsorbent polymer can be used alone or in combination of two or more.

[0032] The superabsorbent polymer is used, for example, in the form of particles, fibers, etc. Preferably, it is used in the form of particles from the viewpoint of ease of handling. At this time, by avoiding the use of a superabsorbent polymer in the form of fine powder with poor fluidity as a powder and using a superabsorbent polymer having a median particle diameter, the basic performance related to absorption can be enhanced, and the rough tactile sensation generated by the hardening of the absorber 15 can be reduced.

[0033] In the absorber 15, the forms of the absorbent fiber and SAP may be those formed by mixing SAP particles in the absorbent fiber, or a SAP sheet in which SAP particles are fixed between the absorbent fibers. Also, as another form of the absorber 15, an absorbent sheet including a plurality of hydrophilic non-woven fabrics and a superabsorbent polymer fixed between the hydrophilic non-woven fabrics can be used.

[0034] (Absorbent paper) The entire absorbent body 15 may be wrapped with absorbent paper (not shown). As the absorbent paper, any hydrophilic sheet commonly used in this field can be used. For example, hydrophilic non-woven fabrics such as thermal-bonded non-woven fabric, spun-bonded non-woven fabric, air-laid non-woven fabric, air-through non-woven fabric, pulp-containing non-woven fabric, tissue paper, absorbent paper, etc. can be mentioned. Among the hydrophilic non-woven fabrics, hydrophilic non-woven fabrics such as thermal-bonded non-woven fabric, spun-bonded non-woven fabric, air-through non-woven fabric, pulp-containing non-woven fabric are more preferable, and tissue paper (crepe paper), spun-bonded non-woven fabric subjected to hydrophilic treatment as necessary, etc. are even more preferable.

[0035] (Liquid diffusion sheet) A liquid-permeable liquid diffusion sheet (not shown) may be provided between the top sheet 13 and the absorbent body 15. The liquid diffusion sheet diffuses body fluid from the top sheet 13 side and guides it to the absorbent body 15 side. Examples of the liquid diffusion sheet include non-woven fabrics such as air-through non-woven fabric, point-bonded non-woven fabric, spun-bonded non-woven fabric, melt-blown non-woven fabric, and composite non-woven fabrics laminated with spun-bonded / melt-blown, spun-bonded / melt-blown / spun-bonded. The shape of the liquid diffusion sheet is not particularly limited, but in order to allow liquids such as urine to evenly diffuse to the absorbent body 15, it is preferably in a shape that completely covers the surface of the absorbent body 15, or in order to reduce costs, it is preferably in a shape that does not cover the whole.

[0036] (Three-dimensional gathers at the front and back) The three-dimensional gathers 16 at the front and back are sheet-like members for preventing lateral leakage (leakage in the front-back direction) of body fluid excreted by a pet wearing the absorbent article 10 for pets. The three-dimensional gathers 16 at the front and back are arranged on both sides in the width direction (Y direction) of the skin side surface of the top sheet 13 and extend in the longitudinal direction (X direction) and are fixed to the top sheet 13. Note that the object to which the three-dimensional gathers 16 are fixed is not limited to the top sheet 13. For example, in addition to the top sheet 13, the three-dimensional gathers 16 may be fixed to the back sheet 14.

[0037] The sheet constituting the three-dimensional gathers 16 is a liquid-impermeable sheet having water repellency and / or waterproofness, and is composed of, for example, a non-woven fabric. Here, as the non-woven fabric, a water-repellent and / or waterproof (liquid-impermeable) non-woven fabric formed of hydrophobic fibers can be used without particular limitation. For example, a spunbond non-woven fabric, a meltblown non-woven fabric, a composite non-woven fabric (SMS non-woven fabric) which is a spunbond non-woven fabric / meltblown non-woven fabric / spunbond non-woven fabric laminate, a composite non-woven fabric (SMMS non-woven fabric) which is a spunbond non-woven fabric / meltblown non-woven fabric / meltblown non-woven fabric / spunbond non-woven fabric laminate, etc. can be mentioned. Among these, it is preferable that it is an SMS non-woven fabric.

[0038] Elastic stretch members (not shown) may be provided on the front and rear three-dimensional gathers 16. The elastic stretch members are arranged along the longitudinal direction on the front and rear three-dimensional gathers 16, and may impart standing properties to the front and rear three-dimensional gathers 16. As the elastic stretch members, for example, those in the form of filaments, strings, or bands made of natural rubber, synthetic rubber, polyurethane, etc. can be appropriately used.

[0039] (Front and rear side gathers) Front and rear side gathers (not shown) may be provided along the longitudinal direction at both ends in the width direction of the absorbent article 10 for pets. The front and rear side gathers provide elasticity in the longitudinal direction at both ends in the width direction of the absorbent article 10 for pets, and improve the fitness to the body side of the pet.

[0040] (Main body fastening part) The main body fastening part 17 is a detachable part for fastening both sides in the longitudinal direction of the absorbent main body 11 when the absorbent article 10 for pets is worn on the pet, and is provided at one end in the longitudinal direction of the absorbent main body 11. The main body fastening part 17 of the present embodiment is provided along the width direction on the skin side surface at one end in the longitudinal direction of the absorbent main body 11. In the present embodiment, the main body fastening part 17 is provided on the skin side surface at one end in the longitudinal direction of the absorbent main body 11, but it is not limited thereto, and it may be provided on the non-skin side surface at one end in the longitudinal direction of the absorbent main body 11.

[0041] As the main body fixing part 17, it is preferable to use a mechanical hook tape. The mechanical hook tape is a member having a plurality of hooks (not shown), and is a tape detachable from the non-woven fabric. The main body fixing part 17 of the present embodiment is a mechanical hook tape detachable from the non-woven fabric on the non-skin side surface of the absorbent main body 11 (the non-woven fabric 19 of the back sheet 14 in the present embodiment). Note that the "mechanical hook tape" may also be referred to as "mechanical tape" or "hook tape".

[0042] In addition, when using a mechanical hook tape as the main body fixing part 17 as in the present embodiment, a loop material or the like may be fixed at a position corresponding to the mechanical hook tape. Further, the main body fixing part 17 is not limited to the mechanical hook tape, and may be, for example, an adhesive layer made of a hot melt adhesive or the like, an adhesive tape, or the like.

[0043] (Left and right leg attachment parts) As shown in FIGS. 1, 3(a), and 4, the left and right leg attachment parts 12 are members that can be wound around the left and right rear legs of the pet and are formed as separate members from the absorbent main body 11. The left and right leg attachment parts 12 are arranged on one end side (rear end side) in the width direction of the absorbent main body 11 and are fixed to the absorbent main body 11. The left and right leg attachment parts 12 are arranged at intervals from each other in the longitudinal direction. The left and right leg attachment parts 12 are arranged symmetrically with respect to the virtual center line passing through the center in the longitudinal direction of the absorbent body 15 and extending in the width direction. In FIG. 3, only one of the left and right leg attachment parts 12 is shown.

[0044] Each of the left and right leg attachment parts 12 is a single extending member 20 that can be wound around the corresponding rear leg of the pet and extends rearward (outward in the width direction) from the back sheet 14. Since the extending members 20 of the left and right leg attachment parts 12 have substantially the same configuration, hereinafter, only one of them will be described and the description of the other will be omitted.

[0045] The extending member 20 is formed in an elongated belt shape. The proximal end side (front end side in FIGS. 1 and 3(a)) of the extending member 20 is fixed to the absorbent body 11. An extending member fixing portion 21 that can be fixed to the non-woven fabric 19 of the back sheet 14 is provided at the tip end portion (rear end portion in FIGS. 1 and 3(a)) of the extending member 20. Note that winding the extending member 20 around the rear legs of the pet includes not only winding it along the entire circumferential area of the rear legs, but also winding it halfway along the rear side area (left and right side surfaces and the rear surface of the rear legs) of the rear legs so as to hook onto the rear legs from the front side.

[0046] (Shape of the extending member) As shown in FIG. 3(a), the extending member 20 of the present embodiment is formed to be long in the front-rear direction and has a wide portion 20a at the tip end portion (rear end portion). The extending member fixing portion 21, which will be described later, is provided in the wide portion 20a. Thereby, the position of the extending member fixing portion 21 can be made easily understandable.

[0047] (Fixing position of the extending member) The proximal end side of the extending member 20 only needs to be fixed to the absorbent body 11, but it is preferably fixed to the back sheet 14. The proximal end side of the extending member 20 is preferably sandwiched and fixed between the resin film 18 and the non-woven fabric 19 of the back sheet 14, or fixed to the non-skin side surface of the back sheet 14 among the back sheet 14. By adopting such a configuration, interference with the pet's body due to the connection portion between the extending member 20 and the absorbent body 11 can be prevented, so that the discomfort of the pet during wearing can be suppressed.

[0048] (Dimensions of the extending member) The length from the absorbent body 11 to the tip of the extending member 20 (the length along the extending direction) is preferably 50 mm or more and 250 mm or less. The width of the extending member 20 (the length in the direction orthogonal to the extending direction) is preferably 10 mm or more and 50 mm or less. By setting the dimensions of the extending member 20 within the above ranges, it is possible to suppress the discomfort given to the pet while ensuring the strength of the extending member 20. Note that the width of the extending member 20 is the width of the portion of the extending member 20 that is mainly wound around the hind legs of the pet. In the present embodiment, it is the width of the portion narrower than the wider portion 20a.

[0049] (Configuration of the extending member) The extending member 20 preferably includes a non-woven fabric having a basis weight of 70 g / m 2 or more and 100 g / m 2 or less. Further, the extending member 20 more preferably includes an elastic stretchable member that is fixedly provided with respect to the non-woven fabric and is stretchable in the extending direction of the extending member 20.

[0050] As shown in FIG. 4, the extending member 20 of the present embodiment includes two strip-shaped non-woven fabrics 22 having a basis weight of 70 g / m 2 or more and 100 g / m 2 or less and facing each other, and a plurality of elastic stretchable members 23 disposed between the two strip-shaped non-woven fabrics 22 and fixedly provided with respect to the two strip-shaped non-woven fabrics 22. If the basis weight of the strip-shaped non-woven fabric 22 is made lower than 70 g / m 2 , the extending member 20 is likely to break, and the strip-shaped non-woven fabric 22 is likely to stretch, resulting in poor fit. On the other hand, if the basis weight of the strip-shaped non-woven fabric 22 is made higher than 100 g / m 2 , it becomes too hard, which may give discomfort to the pet, and there is a possibility that the hair will become entangled due to rubbing and the skin will be easily chafed.

[0051] The material of the strip-shaped nonwoven fabric 22 is not particularly limited, but is preferably an SMS nonwoven fabric or a spunbond nonwoven fabric, and more preferably a nonwoven fabric containing cellulose-based fibers. By forming the strip-shaped nonwoven fabric 22 with a nonwoven fabric containing cellulose-based fibers, the extending member 20 that is easy to wear and gentle on the skin can be obtained.

[0052] The elastic stretching member 23 is provided along the extending direction of the extending member 20 and is stretchable in the extending direction of the extending member 20. For example, the elastic stretching member 23 is fixed to the two strip-shaped nonwoven fabrics 22 in an extended state. Examples of the elastic stretching member 23 include thread-shaped, string-shaped, and strip-shaped elastic stretching members made of natural rubber, synthetic rubber, polyurethane, etc. By providing the elastic stretching member 23 on the extending member 20, the fitness when the extending member 20 is wound around the rear legs on the left and right of the pet can be improved.

[0053] (Extension member fixing part) The extension member fixing part 21 is a part that detachably fixes the tip side of the extension member 20 to the nonwoven fabric 19 of the back sheet 14, and is provided at the tip of the extension member 20. In this embodiment, the extension member fixing part 21 is provided on the skin side surface of the tip of the extension member 20, but is not limited thereto, and may be provided on the non-skin side surface of the tip of the extension member 20.

[0054] It is preferable to use a mechanical hook tape as the extension member fixing part 21. The mechanical hook tape as the extension member fixing part 21 may be the same as or different from the mechanical hook tape for attaching the absorbent body 11 around the pet's body. When using a mechanical hook tape as the extension member fixing part 21 as in this embodiment, a loop material or the like may be fixed to the absorbent body 11 side. Further, the extension member fixing part 21 is not limited to a mechanical hook tape, and may be, for example, an adhesive layer made of a hot melt adhesive or the like, an adhesive tape, or the like.

[0055] (Modification example of the extension member) In addition, in the present embodiment, the extending member 20 is formed to be long in the front-rear direction, and the wide portion 20a is provided at the tip thereof, but the present invention is not limited thereto.

[0056] For example, as shown in FIG. 3(b), the extending member 20 may be simply formed in a rectangular shape that is long in the front-rear direction. Alternatively, as shown in FIG. 3(c), the extending member 20 may be formed in a curved shape in order to improve the fit to the hind legs of the pet.

[0057] (Usage method) Next, an example of the usage method of the absorbent article 10 for pets will be described. Note that the following usage method of the absorbent article 10 for pets is an example, and it can also be used in other modes.

[0058] FIG. 5 is an explanatory diagram when the absorbent article for pets is attached to a pet. FIG. 6 is an explanatory diagram of the pet wearing the absorbent article for pets viewed from the side. FIG. 7 is an explanatory diagram of the pet wearing the absorbent article for pets viewed from the rear.

[0059] As shown in FIG. 5, when attaching the absorbent article 10 for pets to the pet P, first, with the top sheet 13 side facing the skin side of the pet P and the left and right leg attachment portions 12 at the rear side, the absorbent main body 11 is placed under the waist of the pet P so as to cover the urinary part of the pet P from below. Next, as shown by the white arrow A in FIG. 5, both longitudinal ends of the absorbent main body 11 are lifted, and the absorbent main body 11 is wound around the body of the pet P, and the main body fastening portion 17 on one end side (mechanical hook tape in this embodiment) is fastened to the other end side (see FIGS. 6 and 7). Next, the extension members 20 of the left and right leg attachment portions 12 are wound around the left and right hind legs HL of the pet P, and the extension member fastening portion 21 is fastened to the non-woven fabric 19 of the back sheet 14. For example, as shown by the white arrow B in FIG. 5, by passing the extension member 20 through the inside, the rear side, and the outside of the hind leg HL of the pet P in this order to make the hind leg HL go around half a circle, and then the extension member fastening portion 21 is fastened to the non-woven fabric 19 of the back sheet 14 (see FIG. 6). Thereby, as shown in FIGS. 6 and 7, the absorbent article 10 for pets can be attached to and used on the pet P.

[0060] In this embodiment, the extension member 20 is passed through the inside, the rear side, and the outside of the hind leg HL of the pet P in this order to make the hind leg HL go around half a circle, but it is not limited to this. For example, in the direction opposite to the white arrow shown in FIG. 5, the extension member 20 may be passed through the outside, the rear side, and the inside of the hind leg HL of the pet P in this order to make the hind leg HL go around half a circle. Or, the extension member 20 may be wound around the hind leg HL of the pet P one or more times, and then the extension member fastening portion 21 may be fastened to the non-woven fabric 19 of the back sheet 14.

[0061] In the absorbent article 10 for pets configured as described above, since it is provided with left and right leg attachment portions 12 that can be attached to the left and right hind legs HL of the pet P, the left and right leg attachment portions 12 can be attached to the hind legs HL of the pet P during wearing. Further, since the left and right leg attachment portions 12 are formed as separate members from the absorbent body 11, the left and right leg attachment portions 12 can be molded with a material suitable for attaching to the hind legs HL of the pet P, or attached to the absorbent body 11 in a manner that allows easy movement relative to the absorbent body 11. Therefore, even if the pet P moves violently, rotation of the absorbent article 10 for pets with respect to the body (trunk) of the pet P can be reliably prevented.

[0062] Also, when the absorbent article 10 for pets is worn on the pet P, the pet P's movement may make it difficult to wear the absorbent article 10 for pets, and there may be a case where it is worn loosely around the trunk. Even in such a case, since the left and right leg attachment portions 12 are attached to the hind legs HL of the pet P, rotation and displacement of the absorbent article 10 for pets in the circumferential direction of the trunk can be suppressed, and urine leakage can be prevented.

[0063] Also, even in the case of an absorbent article 10 for pets that does not fit the body shape, rotation of the absorbent article 10 for pets with respect to the trunk of the pet P can be reliably prevented.

[0064] Also, since the left and right leg attachment portions 12 are attached to the hind legs HL of the pet P during wearing, forward displacement (movement) of the absorbent article 10 for pets with respect to the body (trunk) of the pet P can be reliably prevented. Thereby, displacement between the position of a local part of the pet P and the position of the absorbent body 15 can be prevented, and urine leakage is less likely to occur.

[0065] In addition, the left and right leg attachment portions 12 are formed as separate members from the absorbent main body 11 and can be made to move easily with respect to the absorbent main body 11. Therefore, the movement of the absorbent main body 11 caused by the movement of the left and right leg attachment portions 12 can be suppressed. For this reason, the movement of the absorbent main body 11 in the circumferential direction of the body of the pet P caused by the movement of the hind legs HL of the pet P can be suppressed, so that skin abrasions and hair entanglement due to rubbing between the absorbent main body 11 and the body of the pet P can be suppressed.

[0066] In addition, since the left and right leg attachment portions 12 are formed as separate members from the absorbent main body 11, unlike the case where the member that supports the hind legs HL of the pet P and the absorbent main body 11 are integrally molded, they can be easily manufactured and the material cost can be reduced.

[0067] Further, the backsheet 14 has a resin film (film portion) 18 on the skin side and a non-woven fabric (non-woven fabric portion) 19 located on the non-skin side of the resin film 18. For this reason, since the non-woven fabric 19 can be disposed on the surface of the non-skin side of the backsheet 14, the extension member fixing portion 21 of the extension member 20 can be fixed to the non-woven fabric 19 of the backsheet 14. Further, by exposing the non-woven fabric 19 to the outside, the texture of the non-skin side surface of the backsheet 14 can be improved. Also, since the non-woven fabric 19 is exposed to the outside during wearing, a sense of clothing is produced, so the appearance is also favorable.

[0068] Thus, according to the present embodiment, displacement and rotation of the pet absorbent article 10 with respect to the body can be prevented. As a result, displacement between the position of a local part of the pet P and the position of the absorber 15 can be prevented, so that urine leakage is less likely to occur.

[0069] Also, each of the left and right leg attachment parts 12 is a single extension member 20 that can be wound around the corresponding rear leg HL of the pet P. At the tip of the extension member 20, an extension member fastening part 21 that can be fastened to the non-woven fabric 19 of the backsheet 14 is provided. Then, the extension member 20 can be attached to the rear leg HL of the pet P by winding it around the rear leg HL of the pet P and fastening the extension member fastening part 21 at the tip to the non-woven fabric 19 of the backsheet 14. In this way, since each of the left and right leg attachment parts 12 is a single extension member 20 that can easily move relative to the absorbent body 11, the left and right rear legs HL of the pet P to which the extension member 20 is attached can also easily move relative to the absorbent body 11. Therefore, the pet absorbent article 10 can be worn with the pet P in an easily movable state.

[0070] Also, since the tightening can be adjusted according to the thickness of the rear leg HL of the pet P and the extension member 20 can be attached to the rear leg HL, it can correspond to pets P with various thicknesses of the rear leg HL, and the fit is improved.

[0071] Also, by making the main body fastening part 17 into a mechanical hook tape, unlike the case where the main body fastening part 17 is an adhesive layer or an adhesive tape, it is easy to reattach and the length around the body of the pet absorbent article 10 can be easily adjusted.

[0072] Also, by making the extension member fastening part 21 into a mechanical hook tape, unlike the case where the extension member fastening part 21 is an adhesive layer or an adhesive tape, it is easy to reattach and the tightening of the extension member 20 of the left and right leg attachment parts 12 to the left and right rear legs HL of the pet P can be easily adjusted.

[0073] As described above, the present invention has been described based on the above embodiments. However, the present invention is not limited to the contents of the above embodiments, and can be appropriately changed without departing from the scope of the present invention. That is, of course, other embodiments, examples, operation techniques, etc. made by those skilled in the art based on this embodiment are all included in the scope of the present invention.
