[0015] Hereinafter, an absorbent article for pets according to an embodiment of the present invention will be described with reference to the drawings.

[0016] In this specification, the wearing of the absorbent article for pets refers to a state in which the absorbent article for pets is wound around and attached to the body (trunk) of an animal that is a pet, regardless of before or after body fluid absorption. Also, the longitudinal direction of the absorbent article for pets refers to the direction along the circumferential direction (circumference direction) of the pet's trunk when the absorbent article for pets is worn, which is the direction along arrow X in the figure. Further, the inner side in the longitudinal direction means the direction toward the center in the longitudinal direction, and the outer side in the longitudinal direction means the direction away from the center in the longitudinal direction. Also, the width direction of the absorbent article for pets refers to the direction that intersects (is orthogonal to) the longitudinal direction, which is the direction along the front and back of the pet when the absorbent article for pets is worn, and is the direction along arrow Y in the figure. Further, the inner side in the width direction means the direction toward the center in the width direction, and the outer side in the width direction means the direction away from the center in the width direction. Also, the thickness direction of the absorbent article for pets refers to the direction that intersects (is orthogonal to) both the longitudinal direction and the width direction, which is the direction in which each component member is laminated, and is the direction along arrow Z in the figure. Also, the skin side of the absorbent article for pets refers to the direction toward the body side of the pet when the absorbent article for pets is worn in the thickness direction, and the non-skin side refers to the direction opposite to the skin side in the thickness direction. Also, the front-back direction means the front-back direction of the pet when the absorbent article for pets is worn. Also, the body fluid mainly means urine.

[0017] <Absorbent article for pets> FIG. 1 is a plan view from the skin side of an absorbent article for pets according to an embodiment of the present invention. FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1. FIG. 3 is an enlarged view of part III of FIG. 1. FIG. 4 is an explanatory view of a method for manufacturing a leg belt. Note that in FIG. 2, the cross-section of the absorbent article for pets is schematically shown. Also, 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] An absorbent article for pets 10 according to an embodiment of the present invention is worn around the trunk of a pet (for example, a dog, a cat, etc.) and used, and is particularly preferably used for male pets.

[0019] As shown in FIGS. 1 and 2, the absorbent article 10 for pets according to the present embodiment mainly includes an absorbent body 20 that absorbs body fluids, and left and right leg fixing portions 30 that are fixed to the absorbent body 20 and can be attached to the left and right hind legs of the pet.

[0020] (Absorbent body) The absorbent body 20 is a portion that is wound around the pet's torso and is formed to be long in the circumferential direction (X direction) of the pet's torso. The absorbent body 20 includes a liquid-permeable topsheet 21 on the skin side, a liquid-impermeable backsheet 22 on the non-skin side, an absorbent body 23, three-dimensional gathers 24 at the front and rear, and a mechanical hook tape (main body fixing portion) 25 used when winding around the pet's torso. In the present embodiment, the shape of the absorbent body 20 is substantially rectangular, but it is not limited thereto, and the shape of the absorbent body 20 may be at least a belt shape that can be worn around the pet's torso.

[0021] (Dimensions of the absorbent body) The length L1 in the longitudinal direction of the absorbent body 20 is preferably 300 mm or more and 570 mm or less. The length W1 in the width direction (Y direction) of the absorbent body 20 is preferably 180 mm or more and 350 mm or less. By setting the dimensions of the absorbent body 20 within the above range, 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 body 20 within the above range, an absorbent article 10 for pets that can also accommodate pets with a large (thick) torso circumference and a short torso length (for example, dogs) can be obtained.

[0022] (Topsheet) The topsheet 21 may be formed from a base material having liquid permeability such that body fluid moves to the absorber 23. Examples of the base material of the topsheet 21 include, 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, and the like. 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 preferable, and air-through nonwoven fabrics or spunbond nonwoven fabrics are more preferable from the viewpoint of texture.

[0023] The topsheet 21 may be embossed or perforated on the surface in order to improve liquid permeability. As methods 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 21 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 21 is not particularly limited, and it may be a shape that covers the absorber 23 in order to guide body fluid to the absorber 23 without leakage.

[0024] (Backsheet) The backsheet 22 may be formed using a liquid-impermeable base material so that there is no leakage of body fluid held by the absorber 23 to the non-skin side, and may be formed from materials such as a resin film or a composite sheet formed by laminating a resin film and a non-woven fabric. Among these, as shown in FIG. 2, the backsheet 22 preferably has a resin film (film portion) 26 on the skin side and a non-woven fabric (non-woven fabric portion) 27 located on the non-skin side of the resin film 26, and is a composite sheet in which these are laminated. Although FIG. 2 shows the backsheet 22 composed of a composite sheet formed by laminating the resin film 26 and the non-woven fabric 27, it is not limited thereto, and the backsheet 22 may be a single resin film, or may be a backsheet 22 composed of a composite sheet laminated with three or more layers.

[0025] Examples of the resin film 26 used for the backsheet 22 which is a composite sheet include polyester, polyvinyl alcohol, polyethylene, polypropylene, a composite film of polyethylene and polypropylene, and the like.

[0026] The non-woven fabric 27 used for the backsheet 22 which is a composite sheet is not particularly limited in the manufacturing method, and examples thereof include a composite non-woven fabric formed by laminating a plurality of the same kind and / or different kinds of non-woven fabrics such as a spunbond non-woven fabric, a meltblown non-woven fabric, a spunbond non-woven fabric / meltblown non-woven fabric, and a spunbond non-woven fabric / meltblown non-woven fabric / spunbond non-woven fabric, and composite materials thereof.

[0027] It is preferable to provide the backsheet 22 with air permeability in order to prevent stuffiness during wearing. In order to provide the backsheet 22 with air permeability, for example, a filler may be blended into the resin film 26 of the base material, or the backsheet 22 may be embossed. Calcium carbonate can be cited as the filler, and the 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 23 is disposed between the topsheet 21 and the backsheet 22, and absorbs and holds the body fluid that has passed through the topsheet 21. The shape of the absorbent body 23 is not particularly limited, and examples thereof include a rectangular shape and an oval shape.

[0029] Some absorbent bodies 23 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, disposable diapers, urine collection pads, etc. Examples thereof include fluff pulp, cotton, rayon, acetate, tissue, absorbent paper, hydrophilic non-woven fabric, etc. Among these, fluff pulp is preferable from the viewpoint of absorbency. Examples of the fluff pulp include wood pulp (e.g., softwood kraft pulp (N-BKP) such as southern pine and Douglas fir), synthetic fibers, resin fibers, and cotton-like defibrated products such as 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 fluid and prevent backflow. Examples thereof 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 preferable from the viewpoint of the absorption amount per unit weight, alkali metal polyacrylate salts are more preferable, and sodium polyacrylate is even more preferable. The superabsorbent polymer can be used alone or in combination of two or more.

[0032] Superabsorbent polymers are used, for example, in the form of particles, fibers, etc., and are preferably used in particle form from the viewpoint of ease of handling. At this time, by avoiding the use of superabsorbent polymers in the form of fine powder with poor fluidity as a powder and using superabsorbent polymers having a median particle diameter, the basic performance regarding absorption can be enhanced, and the rough touch generated by the hardening of the absorber 23 can be reduced.

[0033] In the absorber 23, the form of the absorbent fiber and the SAP may be one formed by mixing SAP particles in the absorbent fiber, or may be a SAP sheet in which SAP particles are fixed between the absorbent fibers. Further, as another form of the absorber 23, an absorbent sheet including a plurality of hydrophilic nonwoven fabrics and a superabsorbent polymer fixed between the hydrophilic nonwoven fabrics can also be used.

[0034] (Absorbent paper) The entire absorber 23 may be wrapped with absorbent paper (not shown). As the absorbent paper, any hydrophilic sheet commonly used in this field can be used, and examples include hydrophilic nonwoven fabrics such as thermal bonded nonwoven fabric, spunbond nonwoven fabric, airlaid nonwoven fabric, air-through nonwoven fabric, pulp-containing nonwoven fabric, tissue paper, absorbent paper, etc. Among the hydrophilic nonwoven fabrics, hydrophilic nonwoven fabrics such as thermal bonded nonwoven fabric, spunbond nonwoven fabric, air-through nonwoven fabric, pulp-containing nonwoven fabric are more preferable, and tissue paper (crepe paper), spunbond nonwoven fabric subjected to hydrophilic treatment as required, etc. are even more preferable.

[0035] (Liquid diffusion sheet) A liquid-permeable liquid diffusion sheet (not shown) may be provided between the top sheet 21 and the absorber 23. The liquid diffusion sheet diffuses body fluid from the top sheet 21 side and guides it to the absorber 23 side. Examples of the liquid diffusion sheet include non-woven fabrics such as air-through non-woven fabric, point-bonded non-woven fabric, spunbond non-woven fabric, meltblown non-woven fabric, and composite non-woven fabrics obtained by laminating spunbond / meltblown, spunbond / meltblown / spunbond. The shape of the liquid diffusion sheet is not particularly limited, but in order to allow liquid such as urine to uniformly diffuse into the absorber 23, it is preferably in a shape that completely covers the surface of the absorber 23, or in order to reduce costs, it is preferably in a shape that does not cover the whole.

[0036] (Front and rear three-dimensional gathers) The front and rear three-dimensional gathers 24 are sheet-like members for preventing lateral leakage (leakage in the front-rear direction) of body fluid excreted by a pet wearing the absorbent article 10 for pets. The front and rear three-dimensional gathers 24 are arranged on both sides in the width direction (Y direction) of the skin side surface of the top sheet 21 and extend in the longitudinal direction and are fixed to the top sheet 21. Note that the object to which the three-dimensional gathers 24 are fixed is not limited to the top sheet 21. For example, the three-dimensional gathers 24 may be fixed to the back sheet 22 in addition to the top sheet 21.

[0037] The sheet constituting the three-dimensional gathers 24 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. Examples include spunbond non-woven fabric, meltblown non-woven fabric, a composite non-woven fabric (SMS non-woven fabric) that is a spunbond non-woven fabric / meltblown non-woven fabric / spunbond non-woven fabric laminate, and a composite non-woven fabric (SMMS non-woven fabric) that is a spunbond non-woven fabric / meltblown non-woven fabric / meltblown non-woven fabric / spunbond non-woven fabric laminate. Among these, an SMS non-woven fabric is preferable.

[0038] An elastic stretching member (not shown) may be provided on the front and rear three-dimensional gathers 24. The elastic stretching member may be disposed along the longitudinal direction on the front and rear three-dimensional gathers 24 to impart standing properties to the front and rear three-dimensional gathers 24. As the elastic stretching member, for example, a filamentous, string-like, or belt-like member made of natural rubber, synthetic rubber, polyurethane, etc. can be appropriately used.

[0039] (Front and rear side gathers) On both end portions in the width direction of the absorbent body 20, front and rear side gathers (not shown) may be provided along the longitudinal direction. The front and rear side gathers impart elasticity to both end portions in the width direction of the absorbent body 20 to improve the fitness to the pet's body side.

[0040] (Body fastening part) The body fastening part is a detachable part for fastening both sides in the longitudinal direction of the absorbent body 20 to each other when the pet absorbent article 10 is worn on the pet, and is provided at one end portion in the longitudinal direction of the absorbent body 20.

[0041] In the present embodiment, a mechanical hook tape (body fastening part) 25 is used as the body fastening part. The mechanical hook tape 25 of the present embodiment is fixed in a state of extending along the width direction on the non-skin side surface of the back sheet 22 at one end portion in the longitudinal direction of the absorbent body 20. The mechanical hook tape 25 is a member having a plurality of hooks (not shown) on the non-skin side and is a tape detachable from the top sheet 21. By using the mechanical hook tape 25 as the body fastening part, unlike the case where the body fastening part is an adhesive layer or an adhesive tape, reattachment is easy and the length around the body of the pet absorbent article 10 can be easily adjusted. Note that "mechanical hook tape" may also be referred to as "mechanical tape" or "hook tape".

[0042] In addition, when using the mechanical hook tape 25 as the main body fixing part as in this embodiment, a loop material or the like may be fixed at a position corresponding to the mechanical hook tape 25. Further, the main body fixing part is not limited to the mechanical hook tape 25, and may be, for example, an adhesive layer made of a hot melt adhesive or the like, an adhesive tape, or the like. In this embodiment, the main body fixing part (mechanical hook tape 25) is provided on the non-skin side surface (the non-skin side surface of the back sheet 22) at one end in the longitudinal direction of the absorbent article 10 for pets. However, it is not limited to this, and it may be provided on the skin side surface at one end in the longitudinal direction of the absorbent article 10 for pets.

[0043] (Left and right leg fixing parts) As shown in FIGS. 1 and 3, the left and right leg fixing parts 30 are members that can be wound around the left and right rear legs of the pet, are arranged on one end side (rear end side) in the width direction of the absorbent main body 20, and are fixed to the absorbent main body 20. The left and right leg fixing parts 30 are arranged at intervals from each other in the longitudinal direction and extend outward (rearward outside) in the width direction from the absorbent main body 20. The left and right leg fixing parts 30 are arranged symmetrically with respect to the virtual center line extending in the width direction passing through the center in the longitudinal direction of the absorbent body 23. Note that winding the left and right leg fixing parts 30 around the left and right rear legs of the pet includes a state of extending along a partial region in the circumferential direction of the rear legs (for example, the left and right side surfaces and the rear surface of the rear legs).

[0044] (A pair of extending members) Each of the left and right leg fixing parts 30 of this embodiment is composed of a pair of extending members 31a and 31b that extend outward in the width direction from the absorbent main body 20. That is, each leg fixing part 30 is composed of a set of two extending members 31a and 31b. Since the left and right leg fixing parts 30 are arranged symmetrically with respect to the virtual center line extending in the width direction passing through the center in the longitudinal direction of the absorbent body 23, hereinafter, one (right side) leg fixing part 30 (a pair of extending members 31a and 31b) will be described, and the description of the other will be omitted.

[0045] The pair of extending members 31a and 31b are strip-shaped members extending in the front-rear direction, with the front end fixed to the rear end of the absorbent body 20 and the rear end side extending rearward from the absorbent body 20. The pair of extending members 31a and 31b of the present embodiment are formed in a substantially L shape having a strip-shaped main body portion 32 that is long in the front-rear direction and a protruding portion 33 that protrudes in the width direction from the rear end portion of the strip-shaped main body portion 32. The pair of extending members 31a and 31b of the present embodiment are formed symmetrically with respect to each other in the longitudinal direction. In each figure, the length of the strip-shaped main body portion 32 in the Y direction is made longer than the length of the protruding portion 33 in the X direction, but it is not limited thereto, and the length of the protruding portion 33 in the X direction may be made longer than the length of the strip-shaped main body portion 32 in the Y direction.

[0046] The strip-shaped main body portions 32 of the pair of extending members 31a and 31b are arranged spaced apart from each other left and right, and extend linearly in a parallel state rearward along the width direction (Y direction) from the absorbent body 20. The separation distance between the strip-shaped main body portions 32 of the pair of extending members 31a and 31b is set to a distance that allows the rear legs of the pet to be arranged between the two strip-shaped main body portions 32. That is, a space S that allows the rear legs of the pet to be arranged is partitioned between the strip-shaped main body portions 32 of the pair of extending members 31a and 31b.

[0047] The protruding portions 33 of the pair of extending members 31a and 31b protrude in a direction approaching each other. A fixing portion capable of being fixed to the other extending member is provided on the protruding portion 33 of at least one of the pair of extending members 31a and 31b. In the present embodiment, a mechanical hook tape (fixing portion) 34 that functions as a fixing portion is provided on the protruding portion 33 of the extending member 31b on the outer side in the longitudinal direction among the pair of extending members 31a and 31b. The pair of extending members 31a and 31b are arranged with the rear legs of the pet in the space S between them and wound around the rear legs, and the fixing portion (in this embodiment, the mechanical hook tape 34) of the one extending member (in this embodiment, the extending member 31b) is fixed to the other extending member (in this embodiment, the extending member 31a), so that it can be attached to the rear legs of the pet. The mechanical hook tape 34 as the fixing portion may be the same as or different from the mechanical hook tape 25 provided on the absorbent body 20. By using the mechanical hook tape 34 as the fixing portion, unlike the case where the fixing portion is an adhesive layer or an adhesive tape, reattachment is easy, and the tightening of the left and right leg fixing portions 30 with respect to the left and right rear legs of the pet can be easily adjusted.

[0048] In addition, when using the mechanical hook tape 34 as the fixing portion as in the present embodiment, a loop material or the like may be fixed to the other extending member as the counterpart. Further, the fixing portion is not limited to the mechanical hook tape 34, and may be, for example, an adhesive layer made of a hot melt adhesive or the like, an adhesive tape, or the like. Also, in FIGS. 1 and 3, the mechanical hook tape 34 is provided on the extending member 31b located on the outer side in the longitudinal direction among the pair of extending members 31a and 31b, but it is not limited to this, and it may be provided on the extending member 31a located on the inner side in the longitudinal direction instead of the extending member 31b, or may be provided on both of the pair of extending members 31a and 31b.

[0049] The material of the pair of extending members 31a and 31b is not particularly limited, but the basis weight is 70 g / m 2 to 100 g / m or more 2It is preferably formed of the following non-woven fabric. When the basis weight of the non-woven fabric as the extending members 31a and 31b is lower than 70 g / m 2 the extending members 31a and 31b are likely to break, and the extending members 31a and 31b are likely to stretch, resulting in poor fit. On the other hand, when the basis weight of the non-woven fabric as the extending members 31a and 31b is higher than 100 g / m 2 it becomes too hard, which may cause discomfort to the pet, and it may rub and entangle the hair, and the skin may be prone to chafing. Further, the non-woven fabric is preferably an SMS non-woven fabric or a spunbond non-woven fabric, and more preferably a non-woven fabric containing cellulosic fibers. By configuring the extending members 31a and 31b with a non-woven fabric containing cellulosic fibers, the leg fixing portion 30 can be easily worn and gentle on the skin.

[0050] (Fixing position of leg fixing portion) The connection portions of the left and right leg fixing portions 30 (a pair of extending members 31a and 31b in this embodiment) to the absorbent body 20 may be fixed to the non-skin side surface of the backsheet 22. Alternatively, when the backsheet 22 is a composite sheet of the above-described resin film 26 and non-woven fabric 27, the connection portions of the left and right leg fixing portions 30 to the absorbent body 20 may be sandwiched and fixed between the resin film 26 and the non-woven fabric 27 of the backsheet 22. By adopting such a configuration, interference of the connection portions of the left and right leg fixing portions 30 with the pet's body can be prevented, so that the discomfort given to the pet can be suppressed.

[0051] (Dimensions of extending member) The length L2 in the extending direction (Y direction) of the pair of extending members 31a and 31b is preferably 40 mm or more and 120 mm or less. By setting the length L2 in the extending direction of the pair of extending members 31a and 31b within the above range, it is possible to ensure a length that can be wound around the left and right hind legs of the pet, and it is possible to suppress the discomfort given to the pet due to being too long. For example, if the length L2 in the extending direction of the pair of extending members 31a and 31b is made shorter than 40 mm, the extending members 31a and 31b may be too short and it may be difficult for the pet to move. Also, as the pet moves, the extending members 31a and 31b, which are non-woven fabrics, may stretch, and the fit may deteriorate. In addition, the pets that can wear it will be limited to pets with a small size around the legs. On the other hand, if the length L2 in the extending direction of the pair of extending members 31a and 31b is made longer than 120 mm, it will be difficult to make the pair of extending members 31a and 31b fit well along the circumferential direction of the leg, and it will be easy to shift.

[0052] The length W2 from the outer end in the direction (X direction) intersecting the extending direction of one extending member 31a to the outer end of the other extending member 31b is preferably 40 mm or more and 100 mm or less. By setting the length W2 in the direction intersecting the extending direction of the pair of extending members 31a and 31b within the above range, it is possible to sufficiently ensure the separation distance between the extending members 31a and 31b, and it is possible to sufficiently ensure the bandwidth (length in the X direction) of the belt-like main body portion 32 that can ensure the strength of each extending member 31a and 31b, and it is possible to suppress the discomfort given to the pet by the extending members 31a and 31b. For example, if the bandwidth of each extending member 31a and 31b is too wide, the legs may be cramped and it may be difficult for the pet to move. Also, since the contact surface with the legs increases, there is a possibility that the legs may become chafed or the hair may become entangled due to rubbing.

[0053] (Manufacturing method of the extending member) Next, a manufacturing method of the pair of extending members 31a and 31b will be described. FIG. 4 is an explanatory diagram of the manufacturing method of the extending member.

[0054] As a method for manufacturing a pair of extending members 31a and 31b, for example, as shown in Fig. 4(a), there is a method of cutting out a portion through which the legs between the extending members 31a and 31b pass from a rectangular non-woven fabric and dividing it into two, or as shown in Fig. 4(b), a method of cutting out the alternately arranged extending members 31a and 31b from a rectangular non-woven fabric. In these methods, a plurality of pairs of extending members 31a and 31b are manufactured from the non-woven fabric sheet 100 conveyed in a predetermined direction (the direction indicated by the white arrow in the figure; hereinafter referred to as the "conveying direction"). Note that the method for manufacturing a pair of extending members 31a and 31b is not limited to these methods.

[0055] As shown in Fig. 4(a), in the method of cutting out a portion through which the legs between the extending members 31a and 31b pass from a rectangular non-woven fabric and dividing it into two, the conveying direction becomes the short side, and a plurality of rectangular non-woven fabric pieces 101 where the direction intersecting the conveying direction (hereinafter referred to as the "sheet width direction") becomes the long side are continuously arranged in the conveying direction. A plurality of locations on the non-woven fabric sheet 100 are cut in the sheet width direction. Then, a concave cut a1 (for example, a perforation) is made so as to notch from one edge (the upper side in the figure) to the other edge (the lower side in the figure) in the sheet width direction of each non-woven fabric piece 101, and a cut a2 (for example, a perforation) is made at the center in the conveying direction of each non-woven fabric piece 101. Thereby, a pair of extending members 31a and 31b can be formed from each non-woven fabric piece 101. Although this method is suitable for mass production, surplus portions (waste paper) are generated inside the concave cut a1.

[0056] As shown in Fig. 4(b), in the method of cutting out the alternately arranged extending members 31a and 31b from the rectangular nonwoven fabric, a plurality of locations on the nonwoven fabric sheet 100 are cut in the sheet width direction so that a plurality of rectangular nonwoven fabric pieces 101 are continuous in the transport direction in the same manner as described above. Then, a crank-shaped cut a3 is made from one long side to the other long side on one side in the transport direction of each nonwoven fabric piece 101. The crank-shaped cut a3 is made to be point-symmetrical with respect to the center of each nonwoven fabric piece 101. Thereby, a pair of alternately arranged extending members 31a and 31b can be formed from each nonwoven fabric piece 101. In this method, no surplus portion (waste paper) is generated, so the material cost can be suppressed.

[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 view of a pet wearing the absorbent article for pets as viewed from the side. Fig. 6 is an explanatory view of a pet wearing the absorbent article for pets as viewed from the rear.

[0059] As shown in FIGS. 5 and 6, the absorbent article 10 for pets is worn around the body of the pet P such that the longitudinal direction of the absorbent body 20 is the circumferential direction around the body of the pet P, and the width direction is the front-rear direction of the pet P. When attaching the absorbent article 10 for pets to the pet P, first, with the topsheet 21 side facing the skin side of the pet P, the absorbent article 10 for pets is placed under the waist of the pet P so that the left and right leg fixing parts 30 are at the rear side. Next, while covering the urinary part of the pet P from below, both longitudinal ends of the absorbent body 20 are lifted, and the absorbent body 20 is wound around the body of the pet P, and the mechanical hook tape 25 on one end side is locked to the other end side for fixing. Finally, the left and right leg fixing parts 30 are wound around and attached to the left and right hind legs HL of the pet P. For example, in the present embodiment, the hind leg HL of the pet P is disposed in the space S between the pair of extension members 31a and 31b, and the pair of extension members 31a and 31b are wound around to the rear side of the hind leg HL, and the mechanical hook tape 34 (see FIG. 3) of one of the extension members 31b is fixed to the other extension member 31a. Thereby, the absorbent article 10 for pets can be attached to and used on the pet P.

[0060] In the absorbent article 10 for pets configured as described above, the left and right leg fixing parts 30 are provided which are disposed on the rear end side of the absorbent body 20, extend rearward from the absorbent body 20, and can be attached to the left and right hind legs HL of the pet P. Therefore, since the left and right leg fixing parts 30 can be attached to the hind legs HL of the pet P during wearing, even if the pet P moves violently, rotation of the absorbent body 20 with respect to the body (trunk) of the pet P can be reliably prevented.

[0061] Also, even if the absorbent article 10 for pets does not fit the body type, rotation of the absorbent body 20 with respect to the body of the pet P can be reliably prevented.

[0062] Also, since the left and right leg fixing parts 30 are attached to the hind legs HL of the pet P during wearing, forward displacement (movement) of the absorbent body 20 with respect to the body (trunk) of the pet P can be reliably prevented. Thereby, displacement between the local position of the pet P and the position of the absorbent body 23 can be prevented, and urine leakage is less likely to occur.

[0063] In addition, since each of the left and right leg fixing parts 30 is a pair of extending members 31a and 31b that extend outward in the width direction from the absorbent body 20, the tightening can be adjusted according to the thickness of the hind legs HL of the pet P, and the left and right leg fixing parts 30 can be attached to the hind legs HL. Therefore, it is possible to correspond to pets P with various thicknesses of the hind legs HL, and the fit is improved.

[0064] In addition, the pair of extending members 31a and 31b are formed in a substantially L shape having a belt-shaped main body part 32 and protruding parts 33 that protrude from the tip of the belt-shaped main body part 32 in a direction approaching each other, and a mechanical hook tape 34 as a fastening part is provided on the protruding part 33. For example, when the pair of extending members are linear, when attaching the pair of extending members to the hind legs HL of the pet P, the tightening may become too strong. Also, when the fastening part such as the mechanical hook tape after mounting is located on the left and right side surfaces of the hind legs HL, rubbing with the pair of extending members is likely to occur on the left and right side surfaces of the hind legs HL due to the weight of the fastening part. In the absorbent article 10 for pets, since the pair of extending members 31a and 31b are formed in a substantially L shape and a fastening part is provided on the protruding part 33, it becomes easy to attach the pair of extending members 31a and 31b to the hind legs HL of the pet P, and it can be mounted in a state where the tightening to the hind legs HL is suppressed. Also, since the pair of extending members 31a and 31b are formed in a substantially L shape, the pair of extending members 31a and 31b can be attached along the circumferential direction of the hind legs HL in a state where the tightening is suppressed, and rubbing of the pair of extending members 31a and 31b against the hind legs HL can be suppressed.

[0065] As described above, according to the present embodiment, it is possible to provide an absorbent article 10 for pets that can prevent displacement and rotation with respect to the body. Thereby, displacement between the local position of the pet P and the position of the absorbent body 23 can be prevented, so that urine leakage is less likely to occur.

[0066] Also, when attaching the pet absorbent article 10 to the pet P, the pet P may move, making it difficult to attach the pet absorbent article 10, and the absorbent main body 20 may be loosely attached. Even in such a case, since the left and right leg fixing parts 30 are attached to the hind legs HL of the pet P, rotation and displacement of the pet absorbent article 10 in the body circumferential direction can be suppressed, and urine leakage can be prevented.

[0067] Also, each of the left and right leg fixing parts 30 is a pair of extending members 31a, 31b extending outward in the width direction from the absorbent main body 20. Therefore, the movement of the hind legs HL of the pet P is less likely to be restricted by the absorbent main body 20 attached around the body. For this reason, since the pet P is easy to move, stress applied to the pet can be suppressed.

[0068] Also, each of the left and right leg fixing parts 30 is a pair of extending members 31a, 31b extending outward in the width direction from the absorbent main body 20. Therefore, the movement of the absorbent main body 20 caused by the movement of the hind legs HL of the pet P can be suppressed. For this reason, the occurrence of skin chafing and hair entanglement due to rubbing between the absorbent main body 20 and the body of the pet P can be suppressed.

[0069] Also, since the left and right leg fixing parts 30 separate from the absorbent main body 20 are fixed to the absorbent main body 20, unlike the case where a member supporting the hind legs HL of the pet P and the absorbent main body 20 are integrally molded, it can be easily manufactured, and the material cost can be reduced.

[0070] Also, it is preferable to provide fastening portions (in this embodiment, mechanical hook tapes 34) on both of the pair of extending members 31a and 31b. For example, when the fastening portion is provided only on one of the extending members 31b, if the hind legs HL of the pet P are extremely thin with respect to the space S between the extending members 31a and 31b, the tip side of one of the extending members 31b can be fastened to the other extending member 31a side by the fastening portion. However, the tip side of the other extending member 31a will remain hanging loose. In this case, when the pet P makes intense movements, the pair of extending members 31a and 31b are likely to come off from each other. On the other hand, when the fastening portions are provided on both of the pair of extending members 31a and 31b, even if the hind legs HL of the pet P are extremely thin with respect to the space S between the extending members 31a and 31b, the tip sides of both of the pair of extending members 31a and 31b can be fastened to the other side by the fastening portions. Therefore, even when the pet P makes intense movements, both of the pair of extending members 31a and 31b are firmly fastened at two locations and are difficult to come off.

[0071] Further, by making the back sheet 22 a composite sheet formed by laminating a resin film (film portion) 26 on the skin side and a non-woven fabric (non-woven fabric portion) 27 located on the non-skin side of the resin film 26, the non-woven fabric 27 is exposed to the outside during wearing. Therefore, the feel of the non-skin side surface of the back sheet 22 can be improved. Also, since the non-woven fabric 27 is exposed to the outside during wearing, a clothing-like feel is produced, and the appearance is also favorable.

[0072] As described above, the present invention has been described based on the above embodiment. However, the present invention is not limited to the content of the above embodiment, and can be appropriately modified 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.
