[0017] Hereinafter, an absorbent article for pets according to one embodiment of the present invention will be described with reference to the drawings.

[0018] In this specification, wearing of the absorbent article for pets refers to a state in which the absorbent article for pets is wrapped around the body (torso) of an animal pet, regardless of whether it is before or after absorbing bodily fluids. The longitudinal direction (first direction) of the absorbent article for pets refers to the direction along the waist direction (circumferential direction) of the pet when the absorbent article for pets is worn, and is the direction along the arrow X in the figure. The width direction (second direction) of the absorbent article for pets refers to the direction intersecting (orthogonal to) the longitudinal direction, and is the direction along the arrow Y in the figure. The thickness direction of the absorbent article for pets refers to the direction in which each component is laminated, and is the direction along the arrow Z in the figure. 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. The front-rear direction refers to the front-rear direction of the pet when the absorbent article for pets is worn. The bodily fluids mainly refer to urine.

[0019] Fig. 1 is a plan view of the skin side of the absorbent article for pets according to the first embodiment of the present invention. Fig. 2 is a cross-sectional view taken along the line II-II in Fig. 1. Fig. 3 is a cross-sectional view taken along the line III-III in Fig. 1. Fig. 4 is an explanatory view showing a modified example of a leg insertion section. Figs. 2 and 3 each show a cross section of the absorbent article for pets. Furthermore, each drawing does not stipulate the size relationship between the components of the absorbent article for pets, and the dimensions of each component can be appropriately selected from a wide range depending on the purpose of the absorbent article for pets, the type of pet for which it is used, etc.

[0020] <Absorbent articles for pets> The absorbent article for pets 10 according to the first embodiment of the present invention is to be worn by pets (for example, dogs, cats, etc.), and is particularly suitable for use with male pets.

[0021] 1 to 3, the pet absorbent article 10 of this embodiment includes a liquid-permeable top sheet 11 on the skin side, a liquid-impermeable back sheet 12 on the non-skin side, an absorbent body 13, front and rear three-dimensional gathers 14, a mechanical hook tape (fastening part) 15, and a pair of leg insertion parts 16, and is formed long in a first direction (X direction in the figures, hereinafter referred to as "longitudinal direction"). Note that, in this embodiment, the shape of the pet absorbent article 10 is substantially rectangular, but is not limited thereto, and the shape of the pet absorbent article 10 may be at least a belt-like shape that can be worn around the pet's waist.

[0022] The length L of the pet absorbent article 10 in the longitudinal direction is preferably 300 mm or more and 570 mm or less. The length W1 of the pet absorbent article 10 in the second direction (Y direction in the figure, hereinafter referred to as the "width direction") is preferably 180 mm or more and 350 mm or less. By setting the dimensions of the pet absorbent article 10 within the above ranges, a pet absorbent article 10 of a size suitable for pets such as dogs and cats can be obtained. Furthermore, by setting the dimensions of the pet absorbent article 10 within the above ranges, a pet absorbent article 10 that can also be used for pets with a large (thick) waist circumference and a short torso length (for example, dogs) can be obtained.

[0023] (Top sheet) The top sheet 11 may be formed from a substrate having liquid permeability that allows bodily fluids to move to the absorbent 13. Examples of substrates for the top sheet 11 include hydrophilic sheets, composite nonwoven fabrics that are laminates of the same or different hydrophilic sheets, open-ended films such as open-ended polyethylene films, and foamed films such as polyethylene foams and urethane foams. Examples of hydrophilic sheets include air-through nonwoven fabrics, thermal bond nonwoven fabrics, spunlace nonwoven fabrics, and spunbond nonwoven fabrics made from 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.

[0024] The top sheet 11 may be embossed or perforated on its surface to improve liquid permeability. Any known method may be used for embossing or perforating the top sheet 11 without any restrictions. In addition, the top sheet 11 may contain lotion, antioxidant, anti-inflammatory component, pH adjuster, antibacterial agent, moisturizer, etc. to reduce irritation to the skin. The shape of the top sheet 11 is not particularly limited, and may be any shape that covers the absorbent body 13 to guide bodily fluids to the absorbent body 13 without leaking.

[0025] The widthwise length W2 of the top sheet 11 in this embodiment is shorter than the widthwise length W1 of the pet absorbent article 10. The top sheet 11 is disposed along the end (front end) of the widthwise direction of the pet absorbent article 10 that is the front side when worn.

[0026] (Back seat) The back sheet 12 may be formed using a liquid-impermeable substrate so that the body fluid held by the absorbent 13 does not leak to the non-skin side, and is formed from a material such as a resin film or a composite sheet in which a resin film and a non-woven fabric are laminated. Of these, the back sheet 12 is preferably a composite sheet in which a resin film (film portion) 17 on the skin side and a non-woven fabric (non-woven fabric portion) 18 located on the non-skin side of the resin film 17 are laminated together, as shown in Figures 2 and 3.

[0027] Examples of the resin film 17 used in the back sheet 12, which is a composite sheet, include polyester, polyvinyl alcohol, polyethylene, polypropylene, and composite films of polyethylene and polypropylene.

[0028] The nonwoven fabric 18 used in the back sheet 12, which is a composite sheet, is not particularly limited in its manufacturing method, and examples thereof include composite nonwoven fabrics obtained by laminating multiple identical and / or different types of nonwoven fabrics, such as spunbond nonwoven fabric, meltblown nonwoven fabric, spunbond nonwoven fabric / meltblown nonwoven fabric, and spunbond nonwoven fabric / meltblown nonwoven fabric / spunbond nonwoven fabric, and composite materials thereof.

[0029] It is preferable that the back sheet 12 has breathability to prevent stuffiness during wear. In order to provide the back sheet 12 with breathability, for example, a filler may be blended into the resin film 17 of the base material, or the back sheet 12 may be embossed. An example of the filler is calcium carbonate, and the blending method may be any known method without limitation. For example, a porous (breathable) resin film can be obtained by kneading a resin and a filler, forming the resulting kneaded product into a film, and removing the filler from the resulting film.

[0030] The length in the width direction of the back sheet 12 in this embodiment is the same as the length W1 in the width direction of the absorbent article for pets 10. The back sheet 12 in this embodiment has an extension portion 19 that extends to one side in the width direction (the direction indicated by the arrow Y in the figure, which is the rear side when worn. Hereinafter, it may be referred to as the "rear side") beyond the top sheet 11. That is, the absorbent article for pets 10 has an extension portion 19 that extends to one side in the width direction beyond the top sheet 11, and the extension portion 19 in this embodiment is included in the back sheet 12. The extension portion 19 of the back sheet 12 is provided with a pair of leg insertion portions 16, which will be described later. Note that, in this embodiment, the extension portion 19 is a partial region of the back sheet 12, but is not limited thereto. For example, another sheet (for example, a sheet constituting the three-dimensional gathers 14, which will be described later) different from the top sheet 11 may be provided so as to extend to one side in the width direction beyond the top sheet 11, and a part of the other sheet may function as the extension portion 19.

[0031] (Absorbent) The absorbent body 13 is disposed between the top sheet 11 and the back sheet 12, and absorbs and retains bodily fluids that have permeated through the top sheet 11. The shape of the absorbent body 13 is not particularly limited, and examples of the shape include a rectangular shape, an oval shape, and the like.

[0032] The absorbent body 13 may contain, for example, absorbent fibers and a highly absorbent polymer as an absorbent base material.

[0033] (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, and urine pads, and examples thereof include fluff pulp, cotton, rayon, acetate, tissue, absorbent paper, hydrophilic nonwoven fabric, etc. Among these, fluff pulp is preferred from the viewpoint of absorbency. Examples of fluff pulp include wood pulp (e.g., coniferous bleached kraft pulp (N-BKP) such as southern pine and Douglas fir), synthetic fiber, resin fiber, cotton-like defibrated material such as non-wood pulp, etc.

[0034] (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, and examples thereof include polyacrylates, polyaspartates, (starch-acrylic acid) graft copolymers, (acrylic acid-vinyl alcohol) copolymers, (isobutylene-maleic anhydride) copolymers, and saponification products thereof. Among these, from the viewpoint of the absorption amount per weight, polyacrylates are preferred, alkali metal polyacrylates are more preferred, and sodium polyacrylate is even more preferred. The superabsorbent polymers can be used alone or in combination of two or more.

[0035] The superabsorbent polymer is used in the form of particles, fibers, etc., for example, but is preferably used in the form of particles from the viewpoint of ease of handling, etc. In this case, by avoiding the use of a fine powder of superabsorbent polymer that has poor flowability as a powder and using a superabsorbent polymer having a medium particle size, it is possible to improve basic absorption performance and reduce the rough feel caused by the absorbent body 13 becoming hard.

[0036] The absorbent fibers and SAP in the absorbent body 13 may be in the form of a mixture of SAP particles in absorbent fibers, or may be in the form of a SAP sheet with SAP particles fixed between absorbent fibers. Another form of absorbent body 13 may be an absorbent sheet including multiple hydrophilic nonwoven fabrics and a superabsorbent polymer fixed between the hydrophilic nonwoven fabrics.

[0037] (Absorbent paper) The entire absorbent 13 may be wrapped in absorbent paper (not shown). As the absorbent paper, any hydrophilic sheet commonly used in this field may be used, for example, hydrophilic nonwoven fabrics such as thermal bonded nonwoven fabrics, spunbonded nonwoven fabrics, airlaid nonwoven fabrics, air-through nonwoven fabrics, and pulp-containing nonwoven fabrics, tissue paper, absorbent paper, etc. Among hydrophilic nonwoven fabrics, hydrophilic nonwoven fabrics such as thermal bonded nonwoven fabrics, spunbonded nonwoven fabrics, air-through nonwoven fabrics, and pulp-containing nonwoven fabrics are more preferred, and tissue paper (crepe paper), spunbonded nonwoven fabrics that have been subjected to hydrophilic treatment as necessary, and the like are even more preferred.

[0038] (Liquid diffusion sheet) A liquid-permeable liquid diffusion sheet (not shown) may be provided between the top sheet 11 and the absorbent body 13. The liquid diffusion sheet diffuses bodily fluids from the top sheet 11 side and guides them to the absorbent body 13 side. Examples of the liquid diffusion sheet include nonwoven fabrics such as air-through nonwoven fabrics, point-bonded nonwoven fabrics, spunbonded nonwoven fabrics, melt-blown nonwoven fabrics, and composite nonwoven fabrics obtained by laminating spunbond / melt-blown and spunbond / melt-blown / spunbond. The shape of the liquid diffusion sheet is not particularly limited, but it is preferably a shape that can completely cover the surface of the absorbent body 13 so that liquids such as urine are diffused throughout the absorbent body 13.

[0039] (Front and back gathers) The front and back three-dimensional gathers 14 are sheet-like members for preventing lateral leakage (leakage in the front-rear direction) of bodily fluids excreted by a pet wearing the pet absorbent article 10. The front and back three-dimensional gathers 14 are disposed on both sides in the width direction (Y direction) of the skin side of the top sheet 11, extend in the longitudinal direction, and are fixed to the top sheet 11. Note that the object to which the three-dimensional gathers 14 are fixed is not limited to the top sheet 11; for example, the three-dimensional gathers 14 may be fixed to the back sheet 12 in addition to the top sheet 11.

[0040] The sheet constituting the three-dimensional gathers 14 is a liquid-impermeable sheet having water-repellent and / or waterproof properties, and is made of, for example, a nonwoven fabric. As the nonwoven fabric, any water-repellent and / or waterproof (liquid-impermeable) nonwoven fabric made of hydrophobic fibers can be used without any particular limitation, and examples thereof include spunbond nonwoven fabric, meltblown nonwoven fabric, composite nonwoven fabric (SMS nonwoven fabric) which is a spunbond nonwoven fabric / meltblown nonwoven fabric / spunbond nonwoven fabric laminate, and composite nonwoven fabric (SMMS nonwoven fabric) which is a spunbond nonwoven fabric / meltblown nonwoven fabric / meltblown nonwoven fabric / spunbond nonwoven fabric laminate. Among these, SMS nonwoven fabric is preferable.

[0041] Elastic stretchable members (not shown) may be provided on the front and back three-dimensional gathers 14. The elastic stretchable members may be arranged along the longitudinal direction of the front and back three-dimensional gathers 14 to impart standing ability to the front and back three-dimensional gathers 14. As the elastic stretchable member, for example, thread-, string- or band-shaped members made of natural rubber, synthetic rubber, polyurethane or the like may be appropriately used.

[0042] (Front and back side gathers) Front and rear side gathers (not shown) may be provided along the longitudinal direction at both widthwise ends of the pet absorbent article 10. The front and rear side gathers provide stretchability to both widthwise ends of the pet absorbent article 10, improving the fit to the pet's body.

[0043] (Fastening part) The fastening portion is a part for fastening both longitudinal sides of the pet absorbent article 10 to each other when the pet absorbent article 10 is put on a pet, and is provided at one longitudinal end of the pet absorbent article 10.

[0044] In this embodiment, a mechanical hook tape (fastening part) 15 is used as the fastening part. The mechanical hook tape 15 is fixed to the non-skin side 12a of the backsheet 12 at one end in the longitudinal direction of the pet absorbent article 10 in a state of extending along the width direction. The mechanical hook tape 15 is a member having a plurality of hooks (not shown) on the non-skin side, and is a tape that is detachable from the topsheet 11. Note that the "mechanical hook tape" may also be called a "mechanical tape" or a "hook tape".

[0045] When the mechanical hook tape 15 is used as the fastening part as in this embodiment, a loop material or the like may be fixed at a position corresponding to the mechanical hook tape 15. The fastening part is not limited to the mechanical hook tape 15, and may be, for example, an adhesive layer made of a hot melt adhesive or the like, or an adhesive tape. In this embodiment, the fastening part (mechanical hook tape 15) is provided on the non-skin side (non-skin side 12a of the back sheet 12) of one end in the longitudinal direction of the absorbent article for pet 10, but is not limited thereto and may be provided on the skin side of one end in the longitudinal direction of the absorbent article for pet 10.

[0046] (A pair of leg insertion parts) The pair of leg insertion portions 16 are portions through which the hind legs of a pet are inserted when the pet absorbent article 10 is worn, and are disposed on one side (rear side) in the width direction of the pet absorbent article 10. The pair of leg insertion portions 16 are disposed spaced apart from each other in the width direction. The pair of leg insertion portions 16 are formed symmetrically with respect to an imaginary center line that passes through the center of the absorber 13 in the longitudinal direction and extends in the width direction.

[0047] The pair of leg insertion parts 16 in this embodiment are provided on the extension part 19. That is, the pair of leg insertion parts 16 are located on one side (rear side) of the top sheet 11 and the three-dimensional gathers 14 in the width direction.

[0048] From the viewpoint of ease of molding, the pair of leg insertion portions are preferably formed by any one of cut-like slits, perforations, or openings.

[0049] The pair of leg insertion parts 16 in this embodiment are formed by cut-like slits 16a extending linearly in the longitudinal direction, as shown in Fig. 1. However, the shape of the slits of the pair of leg insertion parts 16 is not limited to this.

[0050] For example, as shown in Fig. 4(a), a pair of leg insertion parts 16 may have short end slits 16b at both ends of the slit 16a, which extend in a direction perpendicular (intersecting) to the slit 16a. The end slits 16b are provided in a T-shape at both ends of the slit 16a, and extend from both ends of the slit 16a to both the front and rear. In this way, by providing the end slits 16b at both ends of the slit 16a, it is possible to prevent tearing from both ends of the slit 16a.

[0051] Alternatively, as shown in Fig. 4(b), the pair of leg insertion parts 16 may have short end slits 16c at both ends of the slit 16a, extending in a direction intersecting the slit 16a. The end slits 16c extend continuously from both ends of the slit 16a toward the outside in the longitudinal direction and toward one side (or the other side) in the width direction, and are inclined with respect to the slit 16a. In this way, by providing the end slits 16c at both ends of the slit 16a, it is possible to prevent tearing from both ends of the slit 16a.

[0052] 4(c), the pair of leg insertion parts 16 may have holes 16d at both ends of the slit 16a. By providing holes 16d at both ends of the slit 16a in this manner, it is possible to prevent tearing from both ends of the slit 16a.

[0053] In this embodiment, the pair of leg insertion portions 16 are formed by cut-like slits, but this is not limited to this. For example, instead of the slit portions in Figures 1 and 4(a) to 4(c), they may be formed by perforations having a shape similar to that of the slit portions.

[0054] (How to use) Next, there will be described an example of a method of using the pet absorbent article 10. Note that the method of using the pet absorbent article 10 described below is just one example, and the pet absorbent article 10 can also be used in other modes.

[0055] Fig. 5 is an explanatory diagram of a pet wearing an absorbent article for pets, viewed from the side. Fig. 6 is an explanatory diagram of a pet wearing an absorbent article for pets, viewed from the rear.

[0056] As shown in Fig. 5 and Fig. 6, the pet absorbent article 10 is attached to the waist of the pet P so that the longitudinal direction of the absorbent article 10 corresponds to the circumferential direction of the waist of the pet P and the width direction corresponds to the front-rear direction of the pet P. When attaching the pet absorbent article 10 to the pet P, first, the pet absorbent article 10 is placed under the waist of the pet P with the top sheet 11 side facing the skin side of the pet P and the pair of leg insertion portions 16 on the rear side. Next, the hind legs HL of the pet P are inserted into the pair of leg insertion portions 16, and both longitudinal ends of the pet absorbent article 10 are lifted so as to cover the urination area of ​​the pet P from below, and the pet absorbent article 10 is wrapped around the waist of the pet P. Then, while holding one longitudinal end of the pet absorbent article 10 by hand, the other end is pulled and tightened, and the other end is fastened by engaging with the mechanical hook tape 15 on the one end side. This allows the pet absorbent article 10 to be worn by the pet P when in use.

[0057] The pet absorbent article 10 configured as described above includes a pair of leg insertion sections 16 arranged on one side (rear side) in the width direction and spaced apart from each other in the longitudinal direction, so that the hind legs HL of the pet P can be inserted into the pair of leg insertion sections 16 when worn. Therefore, even if the pet P moves vigorously, the pet absorbent article 10 can be reliably prevented from rotating relative to the body (torso) of the pet P. Furthermore, even if the pet absorbent article 10 does not fit the pet P's body shape, the pet absorbent article 10 can be reliably prevented from rotating relative to the torso of the pet P.

[0058] Furthermore, since the hind legs HL of the pet P are inserted through the pair of leg insertion portions 16 when the absorbent article for pet 10 is put on, it is possible to reliably prevent the absorbent article for pet 10 from shifting (moving) in the front-to-rear direction relative to the body (torso) of the pet P.

[0059] Furthermore, when putting the pet absorbent article 10 on the pet P, the pet P may move, making it difficult to put on the pet absorbent article 10, and if the pet is put on loosely around the waist, the mechanical hook tape 15 may come off depending on the movement of the pet P. Even if the mechanical hook tape 15 of the put-on pet absorbent article 10 comes off, the pet absorbent article 10 is hooked on the hind legs HL of the pet P inserted into the pair of leg insertion portions 16, and therefore the pet absorbent article 10 is unlikely to fall off.

[0060] In this way, according to this embodiment, it is possible to prevent the pet absorbent article 10 from shifting or rotating relative to the body. This prevents misalignment between the position of the pet P's private parts and the position of the absorber 13, making urine leakage less likely to occur.

[0061] Moreover, the pair of leg insertion parts 16 are provided in an extending part 19 extending rearward beyond the top sheet 11. Therefore, unlike the case where a pair of leg insertion parts 16 are provided that penetrate both the top sheet 11 and the back sheet 12, the pair of leg insertion parts 16 can be easily provided, and there is no need to provide the top sheet 11 in an unnecessary area (rear area).

[0062] Furthermore, by forming the backsheet 12 into a composite sheet in which a resin film (film portion) 17 on the skin side and a nonwoven fabric (nonwoven fabric portion) 18 located on the non-skin side of the resin film 17 are laminated, the nonwoven fabric 18 is exposed to the outside when worn, improving the feel of the non-skin side of the backsheet 12. In addition, the nonwoven fabric 18 being exposed to the outside when worn gives the garment a clothing-like feel, which also makes for a pleasing appearance.

[0063] Furthermore, by using the mechanical hook tape 15 as the fastening part, unlike when the fastening part is an adhesive layer or adhesive tape, it is easy to reattach, and the length of the waist circumference of the pet absorbent article 10 can be easily adjusted.

[0064] In this embodiment, the back sheet 12 is provided with an extension portion 19 that extends further rearward than the top sheet 11, but this is not limited to this, and the width direction length of the back sheet 12 and the width direction length of the top sheet 11 may be approximately the same length without providing the extension portion 19.

[0065] Next, a second embodiment of the present invention will be described with reference to the drawings. The pet absorbent article 20 of this embodiment differs from the first embodiment in that a pair of leg insertion parts 21 are formed with size-adjustable perforations, and otherwise has the same configuration as the first embodiment. Note that the same components as the first embodiment are given the same reference numerals and their description will be omitted.

[0066] FIG. 7 is a plan view of the absorbent article for pets according to the second embodiment of the present invention, seen from the skin side.

[0067] <Absorbent articles for pets> As shown in FIG. 7, the absorbent article for pet 20 of this embodiment includes a pair of leg insertion portions 21. As shown in FIG.

[0068] The pair of leg insertion portions 21 in this embodiment are portions through which the hind legs of a pet are inserted when the pet absorbent article 20 is worn, and are disposed on one side (rear side) in the width direction of the pet absorbent article 20. The pair of leg insertion portions 21 are disposed spaced apart from each other in the longitudinal direction. The pair of leg insertion portions 21 are formed symmetrically with respect to an imaginary center line that passes through the longitudinal center of the absorbent body 13 and extends in the width direction. The pair of leg insertion portions 21 are provided on the extension portion 19. The pair of leg insertion portions 21 are formed by tearable perforations.

[0069] The pair of leg insertion sections 21 is formed by a first perforation 21a extending in the longitudinal direction and a plurality of second perforations 21b spaced apart from each other in the longitudinal direction and intersecting with the first perforation 21a. The first perforation 21a extends linearly in the longitudinal direction. The second perforations 21b are formed shorter than the first perforation 21a, extend linearly in the width direction, and intersect with the first perforation 21a. The second perforations 21b are provided at least on both ends of the first perforation 21a.

[0070] The number of the second perforations 21b on one side is preferably 4 to 6. If the number of the second perforations 21b on one side is 3 or less, it becomes difficult to accommodate pets with various leg thicknesses. On the other hand, if the number of the second perforations 21b on one side is 7 or more, the pair of leg insertion portions 21 may become unnecessarily long in the longitudinal direction.

[0071] When putting the pet absorbent article 20 on a pet, the first perforation 21a and the second perforation 21b are broken as much as necessary according to the thickness of the pet's legs, and the pet is put on by inserting the hind legs into a pair of leg insertion portions 21.

[0072] In the absorbent article for pet 20 configured as described above, similarly to the first embodiment, it is possible to prevent the absorbent article for pet 20 from shifting or rotating relative to the body. This makes it possible to prevent misalignment between the position of the private parts of the pet P and the position of the absorber 13, making it difficult for urine leakage to occur.

[0073] Furthermore, in the pet absorbent article 20, the size of the pair of leg insertion portions 21 can be formed according to the thickness of the pet's legs, so that it can accommodate pets with various leg thicknesses. Therefore, since the pet absorbent article 20 can be made to fit, it is less likely for the pet absorbent article 20 to rub against the pet's skin, and the occurrence of skin troubles in the pet can be suppressed.

[0074] Next, a third embodiment of the present invention will be described with reference to the drawings. The absorbent article for pets 30 of this embodiment differs from the first embodiment in that a pair of leg insertion parts 31 are formed by openings, and otherwise has the same configuration as the first embodiment. Note that the same components as the first embodiment are denoted by the same reference numerals and their description will be omitted.

[0075] FIG. 8 is a plan view of the skin side of an absorbent article for pets according to the third embodiment of the present invention.

[0076] <Absorbent articles for pets> As shown in FIG. 8, an absorbent article 30 for a pet according to this embodiment includes a pair of leg insertion portions 31. As shown in FIG.

[0077] The pair of leg insertion portions 31 in this embodiment are portions through which the hind legs of a pet are inserted when the pet absorbent article 30 is worn, and are disposed on one side (rear side) of the width direction of the pet absorbent article 30. The pair of leg insertion portions 31 are disposed spaced apart from each other in the longitudinal direction. The pair of leg insertion portions 31 are formed symmetrically with respect to an imaginary center line that passes through the longitudinal center of the absorbent body 13 and extends in the width direction. The pair of leg insertion portions 31 are provided on the extension portion 19. The pair of leg insertion portions 31 are formed by openings.

[0078] The shape of the opening of the pair of leg insertion parts 31 is not particularly limited, and may be, for example, a circle, an ellipse, a square, a rectangle, etc. In this embodiment, the shape of the opening of the pair of leg insertion parts 31 is a circle.

[0079] When putting the absorbent article for pet 30 on a pet, the pet is put on by inserting the hind legs into the pair of leg insertion portions 31 in the same manner as in the first embodiment.

[0080] In the absorbent article for pet 30 configured as described above, similarly to the first embodiment, it is possible to prevent the absorbent article for pet 30 from shifting or rotating relative to the body. This makes it possible to prevent misalignment between the position of the private parts of the pet P and the position of the absorber 13, making it difficult for urine leakage to occur.

[0081] Furthermore, in the absorbent article for pet 30, the pair of leg insertion sections 31 are formed by openings, so that tightness around the pet's legs can be reduced.

[0082] Although the present invention has been described based on the above embodiment, the present invention is not limited to the contents of the above embodiment, and can be modified as appropriate without departing from the scope of the present invention. In other words, all other embodiments, examples, and operational techniques made by those skilled in the art based on this embodiment are naturally included in the scope of the present invention.
