Description

[Technical field]

[0001] The present disclosure relates to absorbent articles for pets. [Background technology]

[0002] As the number of people keeping pets increases, the number of cases where pets are kept indoors is also on the rise, and the use of absorbent articles for pets, such as disposable diapers, for pets is also on the rise. In addition, when taking pets out, it is becoming more common for them to wear absorbent articles for pets to prevent them from soiling their surroundings.

[0003] For example, Patent Document 1 discloses a belly-band-shaped paper diaper for male dogs. This diaper is designed by placing the padding of the main body on the male dog's urinary organs and fixing the left and right belt parts of the main body at the upper part of the dog's waist with adhesive parts attached to the belt parts of the main body while the male dog is still.

[0004] [Patent Document 1] JP 2006-217907 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, the waist circumference (length around the waist) of animals such as dogs can change significantly between when they are hungry and when they are full, and can also change significantly as they lose or gain weight depending on their nutritional state and exercise status. When it comes to pet absorbent articles that are worn around a pet's waist, even a slight increase in the pet's waist circumference can make it difficult to wear them, and it may be necessary to use a pet absorbent article that is one size larger.

[0006] The belly-band-shaped paper diaper for male dogs (absorbent article for pets) described in Patent Document 1 allows the position of the adhesive part that secures the belt when put on to be adjusted according to the dog's body shape, but it cannot absorb changes in waist circumference, nor can it stretch to fit the dog's body shape.

[0007] Therefore, an object of the present disclosure is to provide an absorbent article for pets that can absorb changes in the pet's waist circumference and can be adapted to fit the pet's body shape. [Means for solving the problem]

Each drawing does not specify the size relationship of the components of the pet absorbent article, and the dimensions of each component can be appropriately selected from a wide range depending on the purpose of the pet absorbent article, the type of pet to be used, etc.

[0018] <Absorbent articles for pets> An absorbent article 10 for pets according to one 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.

[0019] As shown in Figures 1 to 3, the absorbent article 10 for pets comprises an absorbent main body 11 that mainly absorbs bodily fluids, an elastic sheet 12 fixed to the absorbent main body 11, and a mechanical hook tape (fastening portion) 13 fixed to the elastic sheet 12.

[0020] [Absorbent body] As shown in Figures 1 to 3, the absorbent body 11 comprises a liquid-permeable top sheet 14 on the skin side, a liquid-impermeable back sheet 15 on the non-skin side, an absorbent body 16, and front and rear three-dimensional gathers 17, and is formed long in a first direction (hereinafter referred to as the "longitudinal direction").

[0021] The longitudinal dimension L1 of the absorbent body 11 is preferably 300 mm or more and 570 mm or less. The widthwise (second direction) dimension W1 of the absorbent body 11 is preferably 180 mm or more and 300 mm or less. By setting the dimensions of the absorbent body 11 within the above range, it is possible to obtain an absorbent article for pets 10 of a size suitable for pets such as dogs and cats. Furthermore, by setting the dimensions of the absorbent body 11 within the above range, it is possible to obtain an absorbent article for pets 10 that can also be used for pets (e.g., dogs) with a large (thick) waist circumference and a short torso length.

[0022] (Top sheet) As shown in Figures 1 and 3, the top sheet 14 may be formed from a substrate having liquid permeability that allows bodily fluids to move to the absorbent 16. Examples of substrates for the top sheet 14 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 foam and urethane foam. 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.

[0023] The top sheet 14 may be embossed or perforated on the surface to improve liquid permeability. Any known method may be used for embossing or perforating the top sheet 14 without any restrictions. In addition, the top sheet 14 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 14 is not particularly limited, and may be any shape that covers the absorbent body 16 to guide bodily fluids to the absorbent body 16 without leaking.

[0024] (Back seat) 2 and 3, the back sheet 15 may be formed using a liquid-impermeable substrate so that the body fluid held by the absorbent 16 does not leak to the non-skin side, and is formed from a material such as a resin film or a composite sheet formed by laminating a resin film and a non-woven fabric. Of these, the back sheet 15 is preferably a composite sheet formed by laminating a resin film (film portion) 18 on the skin side and a non-woven fabric (non-woven fabric portion) 19 located on the non-skin side of the resin film 18, as shown in FIG. 3.

[0025] Examples of the resin film 18 used in the back sheet 15, which is a composite sheet, include polyester, polyvinyl alcohol, polyethylene, polypropylene, and composite films of polyethylene and polypropylene.

[0026] The nonwoven fabric 19 used in the back sheet 15, 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.

[0027] It is preferable that the back sheet 15 has breathability to prevent stuffiness during wearing. In order to provide the back sheet 15 with breathability, for example, a filler may be blended into the resin film 18 of the base material, or the back sheet 15 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.

[0028] (Absorbent) 3, the absorbent body 16 is disposed between the top sheet 14 and the back sheet 15, and absorbs and retains bodily fluids that have permeated through the top sheet 14. The shape of the absorbent body 16 is not particularly limited, and examples of the shape include a rectangular shape, an oval shape, and the like.

[0029] The absorbent body 16 may contain, for example, absorbent fibers and a highly absorbent polymer as an absorbent base material.

[0030] (Absorbent Fiber) The absorbent fiber is not particularly limited as long as it is generally used in absorbent articles such as sanitary napkins, paper diapers, 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.

[0031] (Superabsorbent polymer) The superabsorbent polymer (hereinafter also referred to as "SAP") is not particularly limited as long as it can absorb body fluids and prevent backflow, 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.

[0032] The superabsorbent polymer is used in the form of, for example, particles or fibers, and 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 16 becoming hard.

[0033] The absorbent fibers and SAP in the absorbent body 16 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 bonded between absorbent fibers. Another form of the absorbent body 16 may be an absorbent sheet containing multiple hydrophilic nonwoven fabrics and a superabsorbent polymer bonded between the hydrophilic nonwoven fabrics.

[0034] (Absorbent paper) The entire absorbent 16 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 hydrophilically treated as necessary, and the like are even more preferred.

[0035] (Liquid diffusion sheet) A liquid-permeable liquid diffusion sheet (not shown) may be provided between the top sheet 14 and the absorbent body 16. The liquid diffusion sheet diffuses bodily fluids from the top sheet 14 side and guides them to the absorbent body 16 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 in which spunbond / melt-blown or spunbond / melt-blown / spunbond are laminated. 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 16 so that liquids such as urine are thoroughly diffused into the absorbent body 16.

[0036] (Front and back gathers) 1 and 3, the front and rear three-dimensional gathers 17 are provided along the longitudinal direction near both ends in the width direction (Y direction) of the top sheet 14 and fixed to the top sheet 14, for example, in order to prevent lateral leakage (leakage in the front-rear direction) of bodily fluids excreted by a pet wearing the pet absorbent article 10. Note that the object to which the three-dimensional gathers 17 are fixed is not limited to the top sheet 14, and they may be fixed to the back sheet 15 in addition to the top sheet 14, for example.

[0037] The sheet constituting the three-dimensional gathers 17 is a liquid-impermeable sheet having water-repellent and / or waterproof properties, and is made of, for example, a nonwoven fabric. The nonwoven fabric used here is not particularly limited to any 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. Among these, an SMS nonwoven fabric is preferable.

[0038] Elastic stretchable members (not shown) may be provided on the front and back three-dimensional gathers 17. The elastic stretchable members may be arranged along the longitudinal direction of the front and back three-dimensional gathers 17 to impart standing ability to the front and back three-dimensional gathers 17. As the elastic stretchable member, for example, thread-, string- or band-shaped members made of natural rubber, synthetic rubber, polyurethane, etc. may be appropriately used.

[0039] In this embodiment, the front and back three-dimensional gathers 17 are provided, but the front and back three-dimensional gathers 17 do not necessarily have to be provided.

[0040] (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 body 11. The front and rear side gathers provide stretchability to both widthwise ends of the absorbent body 11, improving the fit to the pet's body.

[0041] [Elastic sheet] 1 and 2, the stretchable sheet 12 is a sheet-like member stretchable in the longitudinal direction, and is fixed to one end 11a of one longitudinal side (the left side in Figs. 1 and 2) of the absorbent main body 11, and extends from the end 11a to the one side of the absorbent main body 11. In this embodiment, the region of the other longitudinal side (the right side in Figs. 1 and 2) of the stretchable sheet 12 is fixed to the non-skin side of the back sheet 15 of the absorbent main body 11.

[0042] (Protrusion amount of elastic sheet) The protruding amount (length of the protruding length) L2 of the stretchable sheet 12 from one end 11a of the absorbent body 11 is preferably 15 mm or more and 180 mm or less. If the protruding amount L2 of the stretchable sheet 12 is shorter than 15 mm, the length of the stretchable area when worn cannot be secured, and it tends to be difficult to absorb changes in the pet's waist circumference and to fit to the body shape. On the other hand, if the protruding amount L2 of the stretchable sheet 12 is longer than 180 mm, it becomes difficult to put on the pet and the fit is lost, so that the absorbent body 11 and the private parts tend to be easily misaligned due to changes in posture when sitting or lying down.

[0043] (Stretchable sheet shape) The stretchable sheet 12 of this embodiment is formed in a concave shape with the widthwise center of the end portion on one side in the longitudinal direction cut out toward the other side in the longitudinal direction. That is, the stretchable sheet 12 has a first region 20a and a second region 20b spaced apart in the widthwise direction in a region protruding toward the one side from one end portion 11a of the absorbent body 11. The first region 20a and the second region 20b extend in the longitudinal direction. The shape of the stretchable sheet 12 is not limited to a concave shape, and may be, for example, a rectangular shape as shown in FIG. 5.

[0044] (Stretchable sheet configuration) Examples of the stretchable sheet 12 include a stretchable PE (polyethylene) sheet, a sheet formed of a nonwoven fabric and a stretch film, and a sheet formed of a nonwoven fabric and a rubber thread. Among these, the stretchable sheet 12 preferably includes a nonwoven fabric and a rubber thread or a stretch film fixed to the nonwoven fabric. For example, as shown in FIG. 4, the stretchable sheet 12 of this embodiment is made of two nonwoven fabrics 21a, 21b and a stretchable film 22 interposed between the two nonwoven fabrics 21a, 21b, and is obtained by, for example, stretching the stretchable film 22 and sandwiching and bonding it between the two nonwoven fabrics 21a, 21b. For example, a polyurethane film can be used as the stretchable film 22. Alternatively, as shown in FIG. 6, the stretchable sheet 12 may be formed of a nonwoven fabric 23 and a rubber thread 24 fixed to the nonwoven fabric 23. In this case, it is preferable that a plurality of rubber threads 24 (for example, two to four) are provided in each of the first region 20a and the second region 20b of the stretchable sheet 12 so as to extend in the longitudinal direction.

[0045] (Stretch rate of elastic sheet) The stretch rate of the stretchable sheet 12 (stretch rate in the longitudinal direction) is preferably 150% or more and 200% or less. The stretch rate means the ratio ((A1-A0)÷A0×100(%)) of the difference (A1-A0) between the length (A1) of the stretchable sheet 12 stretched to the maximum in the longitudinal direction and the natural length (A0) in the unloaded state, divided by the natural length (A0). If the stretch rate of the stretchable sheet 12 is lower than 150%, it tends to be difficult to absorb changes in the pet's waist circumference or to fit the pet to its body shape because the stretch rate is insufficient for the natural length. On the other hand, if the stretch rate of the stretchable sheet 12 is higher than 200%, it tends to be easy for the absorbent body 11 to become misaligned with the private parts due to changes in posture when sitting or lying down. In addition, the absorbent body 16 becomes heavy after urination and sags, and there is a risk that the appropriate wearing position cannot be maintained.

[0046] (Tensile load of elastic sheet) The tensile load when stretching the stretchable sheet 12, whose natural length in the longitudinal direction is 100 mm, to twice the length (200 mm) in the longitudinal direction (hereinafter, sometimes simply referred to as the "tensile load of the stretchable sheet 12") is preferably 2N / 50 mm or more and 4N / 50 mm or less. If the tensile load of the stretchable sheet 12 is lower than 2N / 50 mm, the absorbent body 11 and the private parts tend to be easily misaligned due to changes in posture when sitting or lying down. In addition, the absorbent body 16, which has become heavy after urination, may sag and not be able to maintain the correct wearing position. On the other hand, if the tensile load of the stretchable sheet 12 is higher than 4N / 50 mm, a strong force is required to stretch the stretchable sheet 12, so that it tends to be difficult to absorb changes in the pet's waist circumference and to fit the pet's body shape.

[0047] The tensile load of the elastic sheet 12 is measured by first cutting a sample to a width of 50 mm and a length of 160 mm, and then subjecting it to moisture conditioning and curing for at least 2 hours in an environment with a room temperature of 23°C and a relative humidity of 50%. After that, in the same environment, the sample is clamped in a jig using a Tensilon with a chuck distance of 100 mm, and the tensile load is measured at a tension speed of 300 mm / min at a length that doubles (length 200 mm).

[0048] (Weight of elastic sheet) The basis weight of the stretchable sheet 12 is preferably 70 gsm or more and 100 gsm or less. If the basis weight of the stretchable sheet 12 is less than 70 gsm, it becomes thin and easily stretched, so that the absorbent body 11 and the private parts tend to easily become misaligned due to changes in posture. In addition, the absorbent body 16 becomes heavy after urination and sags, and there is a risk that the appropriate wearing position cannot be maintained. On the other hand, if the basis weight of the stretchable sheet 12 is higher than 100 gsm, it gives a feeling of pressure when worn, which causes discomfort to the pet. In addition, the poor breathability makes it easier for skin troubles such as rashes due to sweating to occur.

[0049] [Fastening part] The fastening portion is a portion 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 on the skin side surface 12a of the end portion on one longitudinal side of the stretchable sheet 12. The fastening portion can be fastened to the back sheet 15 of the absorbent main body 11.

[0050] In this embodiment, a mechanical hook tape 13 is used as the fastening part. The mechanical hook tape (fastening part) 13 is provided at the end of one of the longitudinal directions of both the first region 20a and the second region 20b of the stretchable sheet 12, and is fixed to the skin side surface 12a of the stretchable sheet 12. The mechanical hook tape 13 is a member having a plurality of hooks (not shown) on the skin side, and is a tape that is detachable from the nonwoven fabric 19 on the non-skin side of the back sheet 15 of the pet absorbent article 10. The "mechanical hook tape" may also be called "mechanical tape" or "hook tape".

[0051] In this embodiment, since the stretchable sheet 12 has the first region 20a and the second region 20b, the mechanical hook tape 13 is provided in both the first region 20a and the second region 20b, but this is not limited to this. For example, as shown in Fig. 5, when the stretchable sheet 12 is rectangular, the mechanical hook tape 13 may be provided along the width direction on the skin side surface 12a of the end portion on one side in the longitudinal direction of the stretchable sheet 12.

[0052] (Mechanical Hook Tape Dimensions) The longitudinal dimension L3 of the mechanical hook tape 13 is preferably 20 mm or more and 50 mm or less. In addition, the widthwise dimension W2 of the mechanical hook tape 13 is preferably 20 mm or more and 40 mm or less when the stretchable sheet 12 is formed in a concave shape and has the first region 20a and the second region 20b as in this embodiment. On the other hand, as shown in FIG. 5, when the stretchable sheet 12 is formed in a rectangular shape, the widthwise dimension W2 of the mechanical hook tape 13 is preferably 80 mm or more and 300 mm or less. That is, the widthwise dimension W2 of the mechanical hook tape 13 is preferably 20 mm or more and 300 mm or less. By setting the dimensions of the mechanical hook tape 13 within the above range, it is possible to impart sufficient holding power to changes in movement and posture. In addition, the area of ​​the mechanical hook tape 13 is unlikely to be excessive when worn, and pet hair is unlikely to be entangled in the mechanical hook tape 13.

[0053] When the mechanical hook tape 13 is used as the fastening part as in this embodiment, a loop material or the like corresponding to the mechanical hook tape 13 may be fixed to the non-skin side of the back sheet 15 of the pet absorbent article 10. In addition, the fastening part is not limited to the mechanical hook tape 13, and may be, for example, an adhesive layer made of a hot melt adhesive or an adhesive tape.

[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. 7 is an explanatory diagram showing how to use the absorbent article for pets.

[0056] As shown in FIG. 7, the pet absorbent article 10 is attached to the waist of the pet P so that its longitudinal direction corresponds to the circumferential direction of the waist of the pet P and its 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 skin side of the absorbent body 11 is placed below the waist of the pet P so as to cover the urination area of ​​the pet P from below, and both ends of the pet absorbent article 10 in the longitudinal direction are lifted upward to wrap the absorbent body 11 around the waist of the pet P. Then, while holding the other end of the pet absorbent article 10 in the longitudinal direction with a hand, the stretchable sheet 12 on one end side is stretched in the longitudinal direction while the mechanical hook tape 13 is attached to the non-skin side of the back sheet 15 of the absorbent body 11 (non-skin side nonwoven fabric 19 in this embodiment). This allows the pet absorbent article 10 to be attached to the pet P and used.

[0057] The absorbent article for pet 10 configured as described above comprises an absorbent main body 11, a stretchable sheet 12 that extends from one end 11a of the absorbent main body 11 to the one side and has stretchability in the longitudinal direction, and a mechanical hook tape (fastening portion) 13 provided on the skin side 12a of the stretchable sheet 12. Therefore, even if the waist circumference (length of the waist) of the pet P changes significantly temporarily when the pet absorbent article 10 is worn on the pet P (for example, there is a temporary large change between when the pet is hungry and when the pet is full), the change in the waist circumference of the pet P can be absorbed by the stretchability of the stretchable sheet 12.

[0058] Even if the pet P loses or gains weight depending on its nutritional status, exercise status, etc., and the pet P's body shape changes and its waist circumference changes significantly, the absorbent body 11 can be adapted to fit the change in body shape due to the elasticity of the elastic sheet 12. This makes it possible to avoid having to purchase a new pet absorbent article that is one size larger or smaller.

[0059] In addition, since the fastening portion (mechanical hook tape 13 in this embodiment) can be fastened to the back sheet 15 of the absorbent body 11, the area where the fastening portion can be fastened is substantially the entire area of ​​the non-skin side of the back sheet 15. Therefore, the pet absorbent article 10 can be widely adapted to various sizes of pets P, from pets P with small waist circumferences to pets P with large waist circumferences, and the absorbent body 11 can be made to fit to the body shape. In addition, even if the pet P loses or gains weight, the body shape changes and the waist circumference changes significantly, the absorbent body 11 can be made to fit to the change in body shape. This makes it possible to avoid purchasing a new pet absorbent article that is one size larger or smaller.

[0060] Thus, according to this embodiment, it is possible to provide an absorbent article for pets 10 that can absorb changes in the waist circumference of the pet P and can be adapted to fit the pet's body shape.

[0061] Furthermore, by making the back sheet 15 into a composite sheet obtained by laminating a resin film (film portion) 18 on the skin side and a nonwoven fabric (nonwoven fabric portion) 19 located on the non-skin side of the resin film 18, the back sheet 15 can be made suitable for engaging the mechanical hook tape 13.

[0062] Furthermore, by using the mechanical hook tape 13 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 absorbent article for pets 10 can be easily adjusted.

[0063] 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.
