Furthermore, the drawings do not stipulate the dimensional relationship between the components of the pet absorbent article, and the dimensions of each component can be appropriately selected from a wide range depending on the intended use of the pet absorbent article, the type of pet for which it is intended to be used, etc.

[0020] The absorbent article for pets 10 according to one embodiment of the present invention is to be worn around the waist of a pet (for example, a dog, a cat, etc.), and is particularly suitable for use with male pets.

[0021] As shown in Figures 1 and 2, the pet absorbent article 10 of this embodiment comprises an absorbent main body 20 that mainly absorbs bodily fluids, and left and right leg fixing portions 30L, 30R that are fixed to the absorbent main body 20 and can be attached to the left and right hind legs of a pet.

[0022] (Absorbent body) The absorbent main body 20 is a portion that is wrapped around the waist of a pet and is formed long in the direction of the pet's waist (X direction). The absorbent main body 20 has a liquid-permeable top sheet 21 on the skin side, a liquid-impermeable back sheet 22 on the non-skin side, an absorber 23, front and rear three-dimensional gathers 24, and a mechanical hook tape (fastening part) 25 that is used when wrapping around the waist of a pet. Note that, in this embodiment, the shape of the absorbent main body 20 is approximately rectangular, but is not limited to this and the shape of the absorbent main body 20 may be at least a belt-like shape that can be worn around the waist of a pet.

[0023] (Absorbent body dimensions) The length L of the absorbent main body 20 in the longitudinal direction (X direction) is preferably 300 mm or more and 570 mm or less. The length W of the absorbent main body 20 in the width direction (Y direction) is preferably 180 mm or more and 350 mm or less. By setting the dimensions of the absorbent main body 20 within the above ranges, it is possible to obtain a pet absorbent article 10 of a size suitable for pets such as dogs and cats. Furthermore, by setting the dimensions of the absorbent main body 20 within the above ranges, it is possible to obtain a pet absorbent article 10 that can be used for pets (such as dogs) with a large waist circumference (thick) and a short torso length.

[0024] (Top sheet) The top sheet 21 may be formed from a liquid-permeable substrate that allows bodily fluids to move to the absorbent body 23. Examples of substrates for the top sheet 21 include hydrophilic sheets, composite nonwoven fabrics that are laminates of the same or different hydrophilic sheets, apertured films such as apertured polyethylene films, and foamed films such as polyethylene foam and urethane foam. Examples of hydrophilic sheets include air-through nonwoven fabrics, thermal-bonded nonwoven fabrics, spunlace nonwoven fabrics, and spunbonded nonwoven fabrics made from synthetic fibers made from synthetic resins such as polypropylene and polyethylene, recycled fibers such as rayon, and natural fibers such as cotton. Of these, nonwoven fabrics are preferred, and air-through nonwoven fabrics or spunbonded nonwoven fabrics are more preferred from the standpoint of texture.

[0025] The surface of the top sheet 21 may be embossed or perforated to improve liquid permeability. Any known method can be used for embossing or perforating the top sheet 21 without any restrictions. Furthermore, to reduce irritation to the skin, the top sheet 21 may contain lotion, antioxidants, anti-inflammatory ingredients, pH adjusters, antibacterial agents, moisturizers, etc. The shape of the top sheet 21 is not particularly limited, and may be any shape that covers the absorbent body 23 and guides bodily fluids to the absorbent body 23 without leaking.

[0026] (back seat) The backsheet 22 may be formed using a liquid-impermeable substrate to prevent leakage of bodily fluids held in the absorber 23 to the non-skin side, and may be formed from a material such as a resin film or a composite sheet formed by laminating a resin film and a nonwoven fabric. Among these, the backsheet 22 is preferably a composite sheet formed by laminating a resin film (film portion) 26 on the skin side and a nonwoven fabric (nonwoven fabric portion) 27 located on the non-skin side of the resin film 26, as shown in Fig. 2. Note that Fig. 2 illustrates the backsheet 22 formed by a composite sheet formed by laminating the resin film 26 and the nonwoven fabric 27, but the backsheet 22 is not limited thereto and may be a backsheet 22 formed of a single resin film, or a backsheet 22 formed by a composite sheet formed by laminating three or more layers.

[0027] Examples of the resin film 26 used in the backsheet 22 include polyester, polyvinyl alcohol, polyethylene, polypropylene, and composite films of polyethylene and polypropylene.

[0028] The nonwoven fabric 27 used in the back sheet 22, which is a composite sheet, is not particularly limited by its manufacturing method, and examples thereof include composite nonwoven fabrics formed by laminating multiple identical and / or different 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] The back sheet 22 is preferably breathable to prevent stuffiness during wear. To provide breathability to the back sheet 22, for example, a filler may be blended into the base resin film 26 or the back sheet 22 may be embossed. An example of the filler is calcium carbonate, and the blending method can 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] (absorber) The absorbent body 23 is disposed between the top sheet 21 and the back sheet 22, and absorbs and retains bodily fluids that have permeated through the top sheet 21. The shape of the absorbent body 23 is not particularly limited, and examples thereof include a rectangular shape, an oval shape, and the like.

[0031] The absorbent body 23 may contain, for example, absorbent fibers and a superabsorbent polymer (hereinafter sometimes referred to as "SAP") as an absorbent base material.

[0032] (absorbent fiber) The absorbent fiber is not particularly limited as long as it is one generally used in absorbent articles such as sanitary napkins, disposable diapers, and urine absorption pads, and examples thereof include fluff pulp, cotton, rayon, acetate, tissue, absorbent paper, and hydrophilic nonwoven fabrics. Among these, fluff pulp is preferred from the viewpoint of absorbency. Examples of fluff pulp include wood pulp (e.g., bleached coniferous kraft pulp (N-BKP) such as southern pine and Douglas fir), synthetic fibers, resin fibers, and cotton-like defibrated materials such as non-wood pulp.

[0033] (Super absorbent polymer) The SAP is not particularly limited as long as it can absorb body fluids and prevent reflux, and examples thereof include polyacrylates, polyaspartates, (starch-acrylic acid) graft copolymers, (acrylic acid-vinyl alcohol) copolymers, (isobutylene-maleic anhydride) copolymers, and saponified products thereof. Among these, from the viewpoint of absorption per weight, polyacrylates are preferred, alkali metal polyacrylates are more preferred, and sodium polyacrylate is even more preferred. One SAP can be used alone, or two or more SAPs can be used in combination.

[0034] SAP 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 SAP in the form of a fine powder that has poor fluidity as a powder and using SAP with a medium particle size, it is possible to improve basic absorption performance and reduce the rough feel that occurs when the absorbent body 23 hardens.

[0035] The absorbent fibers and SAP in the absorbent body 23 may be in the form of a mixture of absorbent fibers and SAP particles, or may be an SAP sheet with SAP particles fixed between absorbent fibers. Another form of absorbent body 23 is an absorbent sheet containing multiple hydrophilic nonwoven fabrics and SAP fixed between the hydrophilic nonwoven fabrics.

[0036] (absorbent paper) The entire absorber 23 may be wrapped in absorbent paper (not shown). Any hydrophilic sheet commonly used in this field can be used as the absorbent paper, and examples include hydrophilic nonwoven fabrics such as thermal-bonded nonwoven fabrics, spun-bonded nonwoven fabrics, air-laid nonwoven fabrics, air-through nonwoven fabrics, and pulp-containing nonwoven fabrics, tissue paper, and absorbent paper. Among hydrophilic nonwoven fabrics, hydrophilic nonwoven fabrics such as thermal-bonded nonwoven fabrics, spun-bonded nonwoven fabrics, air-through nonwoven fabrics, and pulp-containing nonwoven fabrics are more preferred, and tissue paper (crepe paper) and spun-bonded nonwoven fabrics that have been subjected to a hydrophilic treatment as necessary are even more preferred.

[0037] (liquid diffusion sheet) A liquid-permeable liquid diffusion sheet (not shown) may be provided between the top sheet 21 and the absorbent body 23. The liquid diffusion sheet diffuses bodily fluids from the top sheet 21 side and guides them to the absorbent body 23 side. Examples of liquid diffusion sheets include nonwoven fabrics such as air-through nonwoven fabrics, point-bonded nonwoven fabrics, spunbonded nonwoven fabrics, and melt-blown nonwoven fabrics, as well as composite nonwoven fabrics formed by laminating spunbond / melt-blown or spunbond / melt-blown / spunbond. There are no particular restrictions on the shape of the liquid diffusion sheet, but it is preferable that the shape completely covers the surface of the absorbent body 23 in order to ensure that liquids such as urine are thoroughly diffused throughout the absorbent body 23, or it is preferable that the shape does not cover the entire surface in order to reduce costs.

[0038] (Front and back gathers) The front and rear three-dimensional gathers 24 are sheet-like members that prevent lateral leakage (leakage in the front-to-rear direction) of bodily fluids excreted by a pet wearing the pet absorbent article 10. The front and rear three-dimensional gathers 24 are arranged on both sides of the skin-facing side of the top sheet 21 in the width direction, extend in the longitudinal direction, and are fixed to the top sheet 21 in an upright manner. 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.

[0039] The sheet constituting the three-dimensional gathers 24 is a liquid-impermeable sheet that is water-repellent and / or waterproof, and is made of, for example, a nonwoven fabric. The nonwoven fabric used here is not particularly limited to water-repellent and / or waterproof (liquid-impermeable) nonwoven fabric made of hydrophobic fibers, 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. Of these, SMS nonwoven fabric is preferred.

[0040] Elastic stretchable members (not shown) may be provided on the front and rear three-dimensional gathers 24. The elastic stretchable members may be arranged along the longitudinal direction on the free end sides of the front and rear three-dimensional gathers 24, and may impart standing ability to the front and rear three-dimensional gathers 24. As the elastic stretchable members, thread-, string- or strip-shaped members made of, for example, natural rubber, synthetic rubber, polyurethane or the like may be used as appropriate.

[0041] (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 absorbent main body 20. The front and rear side gathers provide stretchability to both widthwise ends of the absorbent main body 20, improving the fit to the pet's body.

[0042] (Fastening part) The fastening portion is a detachable part for fastening both longitudinal sides of the absorbent main body 20 together when putting the pet absorbent article 10 on a pet, and is provided at one longitudinal end of the absorbent main body 20.

[0043] In this embodiment, a mechanical hook tape (fastening part) 25 is used as the fastening part. The mechanical hook tape 25 in this embodiment is fixed to the non-skin side of the back sheet 22 at one end in the longitudinal direction of the absorbent main body 20 in a state extending along the width direction. The mechanical hook tape 25 is a member having a plurality of hooks (not shown) on the non-skin side, and is a tape that is detachable from the top sheet 21. By using the mechanical hook tape 25 as the fastening part, unlike when the fastening part is an adhesive layer or pressure-sensitive adhesive tape, it is easy to re-apply and the waist length of the pet absorbent article 10 can be easily adjusted. Note that "mechanical hook tape" is also sometimes called "mechanical tape" or "hook tape".

[0044] When the mechanical hook tape 25 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 25. The fastening 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, or a pressure-sensitive adhesive tape. In this embodiment, the fastening part (mechanical hook tape 25) is provided on the non-skin side (non-skin side of the backsheet 22) of one end in the longitudinal direction of the pet absorbent article 10, but is not limited thereto and may be provided on the skin side of one end in the longitudinal direction of the pet absorbent article 10.

[0045] (Left and right leg fixing parts) 1, the left and right leg fixing parts 30L, 30R are members that can be attached to the left and right hind legs of a pet, and are arranged at one end side (rear end side) of the absorbent main body 20 in the width direction, and are fixed to the absorbent main body 20. The left and right leg fixing parts 30L, 30R are arranged spaced apart from each other in the longitudinal direction (X direction), and extend outward in the width direction (rear outer side) from the absorbent main body 20. The left and right leg fixing parts 30L, 30R are arranged symmetrically with respect to an imaginary center line CL that passes through the center of the absorber 23 in the longitudinal direction and extends in the width direction.

[0046] (One set of extension members) In this embodiment, each of the left and right leg fixing portions 30L, 30R is composed of a pair of extension members 31a, 31b extending outward in the width direction from the absorbent main body 20. That is, each of the leg fixing portions 30L, 30R is composed of a pair of extension members 31a, 31b. The left and right leg fixing portions 30L, 30R are disposed symmetrically with respect to an imaginary center line CL that passes through the center of the absorber 23 in the longitudinal direction and extends in the width direction, and therefore, in the following, only one (right) leg fixing portion 30R (a pair of extension members 31a, 31b) will be described, and a description of the other (left) leg fixing portion 30L will be omitted.

[0047] The pair of extension members 31a, 31b are arranged spaced apart from each other on the left and right sides, and extend rearward from the absorbent main body 20. The distance between the pair of extension members 31a, 31b is set to a distance that allows the hind legs of a pet to be placed between the extension members 31a, 31b. In other words, a space S is defined between the pair of extension members 31a, 31b, in which the hind legs of a pet can be placed.

[0048] (One of the extension members) 1, one extension member 31a of a pair of extension members 31a, 31b has an opening 32, and in this embodiment, is arranged inside in the longitudinal direction with respect to the other extension member 31b. Note that the one extension member 31a having the opening 32 may also be arranged outside in the longitudinal direction with respect to the other extension member 31b.

[0049] 3 and 4, one extension member 31a of this embodiment fixes both ends of a strip-shaped nonwoven fabric 33 to the absorbent main body 20, thereby forming an opening 32 as a whole. One extension member 31a of this embodiment is formed in a loop shape by bringing both ends of the linearly extending strip-shaped nonwoven fabric 33 close to or in contact with each other, and both ends of the strip-shaped nonwoven fabric 33 are fixed at approximately the same position on the absorbent main body 20.

[0050] In the present embodiment, one of the extending members 31a is formed as a loop with both ends of the strip-shaped nonwoven fabric 33 close to or in contact with each other, and fixed to the absorbent main body 20 at approximately the same position, but this is not limited thereto. For example, as shown in FIG. 5(a), both ends of the strip-shaped nonwoven fabric 33 may be fixed to the absorbent main body 20 while being spaced apart from each other in the longitudinal direction (X direction). In addition, in the present embodiment, both ends of the linearly extending strip-shaped nonwoven fabric 33 are formed as a loop with both ends close to or in contact with each other, but this is not limited thereto. For example, as shown in FIG. 5(a), both ends of the strip-shaped nonwoven fabric 33 pre-formed in a U-shape may be fixed to the absorbent main body 20. In addition, in the present embodiment, both ends of the strip-shaped nonwoven fabric 33 are fixed to the absorbent main body 20, and the opening 32 is formed as a whole by one of the extending members 31a, but this is not limited thereto. For example, as shown in Figure 5(b), one of the extension members 31a may be a strip-shaped nonwoven fabric 33 having one end fixed to the absorbent main body 20 and having an opening formed on the other end side thereof that functions as the opening 32.

[0051] (The other extension member) 1, the other extension member 31b of the pair of extension members 31a, 31b has a main body portion 34 extending outward in the width direction from the absorbent main body 20, and a locking portion 35 provided on the tip side of the main body portion 34, formed wider than the main body portion 34, and capable of being locked in the opening 32. In this embodiment, the other extension member 31b is disposed outward in the longitudinal direction relative to one extension member 31a. Note that the other extension member 31b having the locking portion 35 may also be disposed inward in the longitudinal direction relative to one extension member 31a.

[0052] 6, the main body 34 of the other extension member 31b in this embodiment is made of a strip-shaped nonwoven fabric 36. One end of the strip-shaped nonwoven fabric 36 is fixed to the absorbent main body 20. The strip-shaped nonwoven fabric 36 constituting the main body 34 of the other extension member 31b preferably has the same strip width (length in the direction intersecting the extension direction) and is made of the same material as the strip-shaped nonwoven fabric 33 of the one extension member 31a.

[0053] As shown in FIG. 6, in this embodiment, locking portion 35 of the other extension member 31b is provided on the other end (tip side) of strip-shaped nonwoven fabric 36 and is formed in a ribbon shape. Ribbon-shaped locking portion 35 has knot portion 35a, left and right wing portions 35b, and left and right hanging portions 35c. The length of left and right wing portions 35b in an unfolded state is formed to be wider than the width of strip-shaped nonwoven fabric 36. In other words, ribbon-shaped locking portion 35 is formed to be wider than main body portion 34. Ribbon-shaped locking portion 35 may be formed by tying a strip-shaped nonwoven fabric extending continuously from strip-shaped nonwoven fabric 36 of main body portion 34 into a ribbon shape, or may be formed by fixing a ribbon (locking portion 35) formed separately from main body portion 34 to the tip of main body portion 34.

[0054] In this embodiment, the locking portion 35 of the other extension member 31b is a ribbon-shaped locking portion 35, but the present invention is not limited to this and various shapes that can be inserted into and locked into the opening 32 can be applied. For example, as shown in FIG. 7, the locking portion 35 that is formed separately from the main body portion 34 and is wider than the main body portion 34 may be fixed to the tip of the main body portion 34.

[0055] When the locking portion 35 is molded separately from the main body 34, the material of the locking portion 35 is not particularly limited, but since it is disposable, an inexpensive and soft material is preferable. For example, the material of the locking portion 35 may be a polyester with a basis weight of 70 g / m 2 More than 300g / m 2The following polyurethane sheets can be used: a thickness of 5.0 mm to 30.0 mm, a mean coefficient of friction (MIU) of 0.3 to 1.0, a mean deviation of the mean coefficient of friction (MMD) of 0.01 to 0.03, and an elongation stress of 3.0 N to 4.5 N when stretched 60 mm. The mean coefficient of friction MIU and mean deviation of the mean coefficient of friction MMD are measured using a friction tester KES-SE (manufactured by Kato Tech Co., Ltd.) by placing a sample on a smooth metal surface and moving a contactor horizontally at a constant speed of 0.1 cm / sec over an area 0.5 cm wide and 2 cm long on the sample. The contactor is made of ten 0.5 mm piano wires, and a load of 50 gf is applied to the contactor. Furthermore, the tensile stress when stretched 60 mm is determined based on JIS P 8113 and JIS P 8111 (temperature and humidity conditions), by holding the sample at equilibrium under temperature and humidity conditions of 23±1°C and 50±2%RH, and then setting a 70 mm long, 25 mm wide sample in an unstretched Tensilon tensile tester with a chuck distance of 50 mm and stretching it 60 mm (220%) at a crosshead moving speed of 300 mm / min, followed by creating an SS curve (horizontal axis is elongation in mm, vertical axis is load in N) for one cycle until the sample returns to its original state. After stretching the unstretched sample 60 mm, the value on the SS curve at the point where it is returned to the unstretched dimension of 50 mm between the chucks is taken as the tensile stress.

[0056] The material of the pair of extension members 31a and 31b is not particularly limited, but is preferably a material having a basis weight of 70 g / m 2 More than 100g / m 2 For example, in this embodiment, the belt-shaped nonwoven fabric 33 constituting one extension member 31a and the belt-shaped nonwoven fabric 36 constituting the main body portion 34 of the other extension member 31b have a basis weight of 70 g / m 2 More than 100g / m 2 The weight of the nonwoven fabric of the extending members 31a and 31b is preferably 70 g / m or less. 2 If the weight of the nonwoven fabric of the extension members 31a, 31b is lower than 100 g / m, the extension members 31a, 31b will be easily broken and will be easily stretched, resulting in poor fit.2 If it is higher than this, it may become too hard and cause discomfort to the pet, and may also cause tangled fur due to rubbing, which may lead to skin irritation.

[0057] Furthermore, the nonwoven fabric used as the extension members 31a, 31b is preferably an SMS nonwoven fabric or a spunbond nonwoven fabric, and more preferably a nonwoven fabric containing cellulosic fibers. By configuring the extension members 31a, 31b from a nonwoven fabric containing cellulosic fibers, the leg fixing parts 30L, 30R can be made easy to put on and gentle on the skin.

[0058] At least one of the strip-shaped nonwoven fabric 33 constituting one extension member 31a and the strip-shaped nonwoven fabric 36 constituting the main body 34 of the other extension member 31b is preferably provided with an elastic, stretchable member 37 along its extension direction. For example, as shown in Figures 3 and 4, one extension member 31a of this embodiment includes two strip-shaped nonwoven fabrics 33 facing each other, and a plurality of elastic, stretchable members 37 arranged between the two strip-shaped nonwoven fabrics 33 and fixed to the two strip-shaped nonwoven fabrics 33.

[0059] (Leg fixing position) The connection portions of the left and right leg fixing portions 30L, 30R (two pairs of left and right extending members 31a, 31b) to the absorbent main body 20 may be fixed to the non-skin side of the back sheet 22. Alternatively, if the back sheet 22 is a composite sheet of the resin film 26 and nonwoven fabric 27 described above, the connection portions of the left and right leg fixing portions 30L, 30R to the absorbent main body 20 may be sandwiched and fixed between the resin film 26 and nonwoven fabric 27 of the back sheet 22. With this configuration, it is possible to prevent the connection portions of the left and right leg fixing portions 30L, 30R from interfering with the pet's body, thereby reducing discomfort to the pet.

[0060] (Dimensions of extension member) The length in the extension direction (Y direction) of the pair of extension members 31a, 31b when they are extended linearly outward in the width direction from the absorbent main body 20 (hereinafter simply referred to as the "length in the extension direction of the pair of extension members 31a, 31b") is preferably 50 mm or more and 120 mm or less. Here, the length in the extension direction of one extension member 31a means the length from the absorbent main body 20 to the rear end of the opening 32. Furthermore, the length in the extension direction of the other extension member 31b means the length from the absorbent main body 20 to the engagement portion 35 (the length of the main body portion 34 in this embodiment). By setting the length in the extension direction of the pair of extension members 31a, 31b within the above range, it is possible to ensure a length that allows them to be wrapped around the left and right hind legs of a pet, and to prevent the pet from feeling uncomfortable if the length is too long. For example, if the length of the pair of extension members 31a, 31b in the extension direction is shorter than 50 mm, the extension members 31a, 31b may be too short, making it difficult for the pet to move, and the extension members 31a, 31b, which are nonwoven fabrics, may stretch as the pet moves, potentially reducing the fit. Furthermore, the pets that can wear the harness are limited to pets with small leg circumferences. On the other hand, if the length of the pair of extension members 31a, 31b in the extension direction is longer than 120 mm, it becomes difficult to properly align the pair of extension members 31a, 31b in the circumferential direction of the leg, making them more likely to slip off.

[0061] The width of the strip-shaped nonwoven fabric 33 constituting one extension member 31a and the strip-shaped nonwoven fabric 36 constituting the main body 34 of the other extension member 31b is preferably 5 mm or more and 20 mm or less. If the width of the strip-shaped nonwoven fabrics 33, 36 is smaller than 5 mm, there is a risk that the strength of the pair of extension members 31a, 31b will not be sufficiently ensured. On the other hand, if the width of the strip-shaped nonwoven fabrics 33, 36 is larger than 20 mm, the legs may be cramped, making it difficult for the pet to move, and the increased contact surface with the legs may cause rashes on the legs due to friction or tangled fur.

[0062] (How to use) Next, we will explain an example of how to use the pet absorbent article 10. Note that the following method of using the pet absorbent article 10 is just one example, and the pet absorbent article 10 can also be used in other ways.

[0063] Fig. 8 is an explanatory diagram showing a pet wearing the pet absorbent article as seen from the side. Fig. 9 is an explanatory diagram showing a pet wearing the pet absorbent article as seen from behind. Fig. 10 is an explanatory diagram showing how to wear the pet absorbent article, with (a) showing a state in which the hind legs are positioned between a pair of extension members, (b) showing a state in which fingers are inserted through the opening of one extension member to pinch the other extension member, (c) showing a state in which the locking portion of the other extension member has been pulled out from the opening of one extension member, and (d) showing a state in which the locking portion of the other extension member is locked into the opening of one extension member.

[0064] As shown in Figures 8 and 9, the pet absorbent article 10 is worn around the waist of the pet P so that the longitudinal direction of the absorbent main body 20 is the circumferential direction of the waist of the pet P and the width direction is the front-to-rear direction of the pet P. When wearing the pet absorbent article 10 on the pet P, first, the top sheet 21 (see Figure 2) side is faced toward the skin of the pet P, and the pet absorbent article 10 is placed under the waist of the pet P so that the left and right leg fixing portions 30L, 30R are at the rear side. Next, both longitudinal ends of the absorbent main body 20 are lifted so as to cover the urination area of the pet P from below, and the absorbent main body 20 is wrapped around the waist of the pet P, and the mechanical hook tape 25 at one end is fastened to the other end to be fastened. Finally, the left and right leg fixing portions 30L, 30R are attached to the left and right hind legs HL of the pet P.

[0065] Next, we will explain how to attach the left leg fixing part 30L to the left hind leg HL of the pet P. Note that when attaching the right leg fixing part 30R to the right hind leg HL of the pet P, the attachment is done in the same way as for the left side.

[0066] When attaching the left leg fixing portion 30L to the left hind leg HL of the pet P, first, as shown in FIG. 10(a), the hind leg HL of the pet P is placed in the space S (see FIG. 1) between the pair of extension members 31a and 31b. Next, as shown in FIG. 10(b), fingers are inserted from the outside into the opening 32 of one extension member 31a and the locking portion 35 of the other extension member 31b is pinched. Next, as shown in FIG. 10(c), while still pinching the locking portion 35 of the other extension member 31b with the fingers, the fingers are removed from the opening 32 of the one extension member 31a and the locking portion 35 of the other extension member 31b is pulled out from the opening 32 of the one extension member 31a. 10(d), when the locking portion 35 of the other extension member 31b is pulled out from the opening 32 of one extension member 31a, the locking portion 35 of the other extension member 31b is locked in the opening 32 of one extension member 31a. This allows the left leg fixing portion 30L to be attached to the left hind leg HL of the pet P. In other words, with the hind leg HL of the pet P positioned between the pair of extension members 31a, 31b, the locking portion 35 of the other extension member 31b is pulled out from the opening 32 of one extension member 31a and the locking portion 35 is hooked into the opening 32, thereby allowing attachment to the hind leg HL of the pet P.

[0067] The pet absorbent article 10 configured as described above includes left and right leg fixing parts 30L, 30R that are arranged on the rear end side of the absorbent main body 20 and fixed to the absorbent main body 20, and that can be attached to the left and right hind legs HL of the pet P. Therefore, since the left and right leg fixing parts 30L, 30R can be attached to the hind legs HL of the pet P when the pet P is put on, it is possible to reliably prevent the absorbent main body 20 from rotating relative to the body (torso) of the pet P even if the pet P moves vigorously.

[0068] Furthermore, even if the pet absorbent article 10 does not fit the pet's body shape, the absorbent main body 20 can be reliably prevented from rotating relative to the pet P's torso.

[0069] Furthermore, since the left and right leg fixing parts 30L, 30R are attached to the hind legs HL of the pet P when the diaper is put on, it is possible to reliably prevent the absorbent main body 20 from shifting (moving) forward relative to the body (torso) of the pet P. This prevents the position of the private parts of the pet P from shifting relative to the position of the absorber 23, making it less likely that urine will leak.

[0070] Furthermore, each of the left and right leg fixing portions 30L, 30R is a pair of extension members 31a, 31b extending outward in the width direction from the absorbent main body 20, one extension member 31a having an opening 32, and the other extension member 31b having a locking portion 35 that can be locked into the opening 32. Therefore, the pair of extension members 31a, 31b can be attached to the hind legs HL of the pet P by the simple process of locking the locking portion 35 of the other extension member 31b into the opening 32 of one extension member 31a.

[0071] Furthermore, the locking portion 35 of the other extension member 31b is locked into the opening 32 of one extension member 31a, so that the locking portion 35 is exposed around the hind legs HL of the pet P. The locking portion 35 of the other extension member 31b is formed wider than the main body portion 34, so that when the pair of extension members 31a, 31b are attached to the hind legs HL of the pet P, the locking portion 35 can function as a design accent. For this reason, by applying various designs to the locking portion 35, such as making the locking portion 35 ribbon-shaped as in this embodiment, it is possible to provide a stylish and cute absorbent article for pet 10 with excellent design.

[0072] Furthermore, after the absorbent body 20 is fitted around the waist of the pet P, the left and right leg fixing parts 30L, 30R can be attached to the hind legs HL of the pet P, making fitting easy.

[0073] As described above, this embodiment can provide the pet absorbent article 10 that can prevent shifting or rotation relative to the body. This prevents shifting between the position of the private parts of the pet P and the position of the absorber 23, making urine leakage less likely to occur.

[0074] 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 causing the absorbent main body 20 to be put on loosely. Even in such a case, because the left and right leg fixing portions 30L, 30R are attached to the rear legs HL of the pet P, rotation or shifting of the pet absorbent article 10 in the waist direction can be suppressed, and urine leakage can be prevented.

[0075] Furthermore, the left and right leg fixing parts 30L, 30R, which are formed as separate members from the absorbent main body 20, are fixed to the absorbent main body 20, so that, unlike when, for example, openings for inserting the hind legs HL are provided in the absorbent main body 20, 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 waist. This allows the pet P to move easily, thereby reducing stress on the pet.

[0076] Furthermore, each of the left and right leg fixing portions 30L, 30R is a pair of extension members 31a, 31b extending outward in the width direction from the absorbent main body 20, and therefore can suppress movement of the absorbent main body 20 caused by movement of the hind legs HL of the pet P. This makes it possible to suppress the occurrence of skin rashes and tangled fur due to friction between the absorbent main body 20 and the body of the pet P.

[0077] Furthermore, since the left and right leg fixing parts 30L, 30R, which are separate from the absorbent main body 20, are fixed to the absorbent main body 20, it can be manufactured easily and material costs can be reduced, unlike when the member supporting the hind legs HL of the pet P and the absorbent main body 20 are integrally molded.

[0078] Furthermore, by arranging the left and right leg fixing parts 30L, 30R symmetrically with respect to an imaginary center line CL that passes through the center of the longitudinal direction of the absorber 23 and extends in the width direction, the left and right leg fixing parts 30L, 30R can be used as a guide for the position of the absorber 23 when attaching the absorbent main body 20 around the waist of the pet P. Therefore, when attaching the absorbent main body 20 around the waist of the pet P, the absorber 23 can be appropriately positioned below the urination area of the pet P using the left and right leg fixing parts 30L, 30R as a guide.

[0079] Furthermore, by making the backsheet 22 a composite sheet obtained by laminating a resin film (film portion) 26 on the skin side and a nonwoven fabric (nonwoven fabric portion) 27 located on the non-skin side of the resin film 26, the nonwoven fabric 27 of the backsheet 22 is exposed to the outside when worn, improving the feel of the non-skin side of the backsheet 22. Furthermore, the exposed nonwoven fabric 27 when worn gives the wearer a clothing-like feel, which also makes for a pleasing appearance.

[0080] In this embodiment, the pair of extension members 31a, 31b are formed from nonwoven fabric (strip-shaped nonwoven fabrics 33, 36), but are not limited to this and may be formed from, for example, cloth strings or the like.

[0081] Although the present invention has been described above based on the above embodiment, the present invention is not limited to the content 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, operational techniques, etc. made by those skilled in the art based on this embodiment are naturally included in the scope of the present invention.
