Description

[Technical Field]

[0001] The present invention relates to an absorbent article for pets. [Background technology]

[0002] In recent years, disposable diapers for pets such as dogs and cats have become known. Some disposable diapers for pets are also known to have a tail hole through which feces can pass (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7341180 Summary of the Invention [Problem to be solved by the invention]

[0004] Some owners of pets such as dogs and cats prefer that when their pets wear diapers and defecate, the feces remain in the diaper, while others prefer that the feces leave the diaper.

[0005] However, diapers that do not allow feces to pass through the tail hole do not allow feces to be expelled from the diaper, while diapers that allow feces to pass through the tail hole do not allow feces to be kept inside the diaper.

[0006] To provide an absorbent article for pets that is configured to allow the tail to be exposed, and that can accommodate a wide variety of dog tails, and also allows the choice of keeping feces inside or letting them out. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention provides: An absorbent article for pets, in which a ventral region covering the abdomen of a pet, a buttocks covering region covering the buttocks including the tail of the pet, and a dorsal region covering the back of the pet are continuous in a first direction, The buttocks covering region includes: a first hole forming section for forming a first hole; a second hole forming portion for forming a second hole that is continuous with the first hole on the back region side, the first hole forming portion forms the first hole by a slit that is convex toward the ventral region side, The second hole forming portion forms the second hole by two perforations extending from each of both ends of the slit toward the back region side, an end portion of the first hole formation portion on the abdominal region side is disposed at a position 50% to 75% of the length of the pet absorbent article in the first direction from the end portion of the pet absorbent article on the abdominal region side, Furthermore, the absorbent article for pets has an absorbent body disposed in a middle portion in a second direction perpendicular to the first direction in at least the abdominal region and the buttocks covering region; stretchable members extending in the first direction on both sides of the absorbent body in the second direction and stretchable in the first direction; The stretchable member is arranged closer to the ventral region than the first hole forming portion, and is not arranged from the end of the first hole forming portion on the ventral region side to the dorsal region side.

[0008] In the present invention configured as described above, when the tail is to be expelled without the stool being expelled, the flap portion formed by the slit in the first hole-forming portion is rolled up to form the first hole, while the perforation in the second hole-forming portion is not broken to form the second hole-forming portion. This allows the tail to be expelled through the first hole, while the stool can be retained within the diaper. On the other hand, when the stool is to be expelled, the flap portion formed by the slit in the first hole-forming portion is rolled up to form the first hole, and then the perforation in the second hole-forming portion is broken to form the second hole. Then, by adjusting the position so that the tail can be expelled through the second hole, the stool can be expelled through the first hole while the tail can be expelled through the second hole.

[0009] In this way, by not forming the second hole when not letting the feces out, and by forming the second hole when letting the feces out, it is possible to choose between keeping the feces inside or letting them out while still allowing the tail to come out. Also, by adjusting the width at which the perforations are broken, it is possible to accommodate a wide variety of dog tails.

[0010] Furthermore, by positioning the end of the first hole forming portion on the ventral region side at a position 50% to 75% of the length of the pet absorbent article in the first direction from the end of the ventral region side of the pet absorbent article, it becomes easier to choose between keeping the feces inside or letting them out while still being able to let the tail out using the first hole forming portion and the second hole forming portion.

[0011] Furthermore, the elastic members that extend in the first direction on both sides of the absorbent body in the second direction and that stretch in the first direction are positioned closer to the ventral region than the first hole forming portion, and are not positioned closer to the dorsal region than the end of the first hole forming portion on the ventral region side, thereby preventing the first hole formed by the first hole forming portion or the second hole formed by the second hole forming portion from being shrunk by the elastic members, making it difficult to pass the tail through.

[0012] The two perforations may be formed so that the distance between them increases as they move away from the slit.

[0013] Such a configuration makes it easier to accommodate pets with thick tails.

[0014] The slit may also be V-shaped.

[0015] In such a configuration, the end on the urination opening side is sharpened to prevent urine leakage.

[0016] Furthermore, the two perforations may each have a rounded curve at the end opposite to the slit.

[0017] In such a configuration, when the perforation is broken, it is possible to prevent the part beyond the perforation from breaking.

[0018] The absorbent body may be disposed so as to sandwich the first and second hole formation portions in the second direction.

[0019] In such a configuration, leakage of urine from the pet due to lateral flow is prevented when the pet is bedridden, for example. [Effects of the Invention]

[0020] According to the present invention, the tail-exposing configuration not only accommodates a wide variety of dog tails, but also allows the choice of keeping feces inside or letting them out. [Brief explanation of the drawings]

[0022] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In each drawing, unless otherwise specified, identical or corresponding components are designated by the same reference numerals and their description may be omitted. In this specification, the front-to-back direction of the pet diaper 1 is designated D1, and the width direction of the pet diaper 1, which is perpendicular to the front-to-back direction, is designated D2. In this specification, the front-to-back direction D1 is the first direction in the present invention and refers to the front-to-back direction of the absorbent body 4, while the width direction D2 is the second direction in the present invention and refers to the width direction of the absorbent body 4. The front-to-back direction corresponds to the front-to-back direction of the pet. In this specification, the front side of the pet diaper 1 and the absorbent body 4 in the front-to-back direction is referred to as the ventral side or front, and the rear side in the front-to-back direction is referred to as the dorsal side or rear. The surface of the pet diaper 1 facing the pet is referred to as the skin side, and the surface of the pet diaper 1 opposite the skin side is referred to as the non-skin side.

[0023] (Overall composition) Fig. 1 is a view of one embodiment of an absorbent article for pets of the present invention as seen from the skin side, and is a plan view in an unfolded state. Fig. 2 is a diagram showing the arrangement of adhesive layers in Fig. 1. Fig. 3 is a diagram showing the II cross section shown in Fig. 1, and Fig. 4 is a diagram showing the II-II cross section shown in Fig. 2.

[0024] 1, this embodiment is a pet diaper 1 having a ventral region F, a buttocks-covering region M, and a dorsal region B, which are continuous in a front-to-back direction D1, which is a first direction. The ventral region F is a region that covers the abdomen of a pet when worn, the buttocks-covering region M is a region that covers the buttocks including the tail of a pet when worn, and the dorsal region B is a region that covers the back of a pet when worn.

[0025] As shown in Figures 1 to 3, the pet diaper 1 comprises a liquid-permeable top sheet 2, a water-proof waterproof sheet 3, an absorbent 4 disposed between the top sheet 2 and the waterproof sheet 3, three-dimensional gathers 7 disposed on both sides of the absorbent 4 in the width direction D2 over the entire front-to-back direction D1 and rising toward the skin side, and a belt-shaped waist sheet 9 extending in the width direction D2 along the abdominal end of the pet diaper 1.

[0026] The absorbent body 4 is positioned in the middle in the width direction D2, spanning a portion of the abdominal region F and a portion of the buttocks-covering region M, so as to be included in both the abdominal region F and the buttocks-covering region M. The absorbent body 4 may be wrapped in a wrapping sheet 5 made of crepe paper, nonwoven fabric, or the like to maintain its shape. The pet diaper 1 may have a backsheet 6 on the non-skin-facing side of the waterproof sheet 3. The pet diaper 1 has side flaps SF on both sides, each composed of the waterproof sheet 3, the backsheet 6, and a gathered sheet 71. The pet diaper 1 may also have end flaps EF, each free of the absorbent body 4, formed by the backsheet 6, the waterproof sheet 3, and the topsheet 2 extending in the front-to-rear direction, and connecting tapes 8, each attached to both sides of the abdominal region F in the width direction D2. A target tape 11 may also be attached to the outer surface of the back region R of the backsheet 6. In this configuration, when putting the pet diaper 1 on a pet, the ventral region F, buttock covering region M and back region B of the pet diaper 1 are placed along the pet's body, and then the connecting tape 8 is brought to the back side and engaged with the target tape 11 provided on the outer surface of the back sheet 6.

[0027] The pet diaper 1 has an overall elongated shape (striped shape) having a predetermined length in the front-to-rear direction D1 and a predetermined width in the width direction D2 perpendicular to the front-to-rear direction. The length of the pet diaper 1 in the front-to-rear direction D1 is preferably 280 mm to 900 mm, and more preferably 340 mm to 540 mm. The length of the pet diaper 1 in the width direction D2 at the center of the length in the front-to-rear direction D1 is preferably 160 mm to 500 mm, and more preferably 170 mm to 340 mm. Note that the "length" referred to here means the length of the pet diaper 1 in its most stretched state after being unfolded. The length of the pet diaper 1 in the front-to-rear direction D1 is 280 mm to 900 mm, and the length of the pet diaper 1 in the width direction D2 at the center of the length in the front-to-rear direction D1 is 160 mm to 500 mm, so that the pet diaper can fit around the legs and waist when worn by a pet. As shown in FIG. 1, the ventral region F, buttocks-covering region M, and back region B may have the shortest length in the width direction D2, with each of the ventral region F and back region B narrowing toward the center in the front-to-back direction D1.

[0028] The buttocks covering region M of the pet diaper 1 is provided with a hole 100 through which the pet's tail can be passed and which allows the user to select whether feces should be retained inside or released from the pet diaper 1. The hole 100 is preferably positioned such that the length L1 from the ventral end E1 of the pet diaper 1 to the end of the hole 100 on the ventral region F side is 50% to 75% of the length L0 in the front-to-rear direction D1 from the ventral end E1 to the dorsal end E2 of the pet diaper 1, and may be, for example, 61%. The detailed shape of the hole 100 will be described later.

[0029] The top sheet 2 is a liquid-permeable sheet that allows excretory fluids such as urine to pass through quickly. Suitable top sheet 2 materials include perforated or non-perforated nonwoven fabrics and porous plastic sheets. The constituent fibers of the nonwoven fabric can be selected without particular limitation, including synthetic fibers (including monocomponent fibers and core-sheath and other composite fibers) such as olefins (e.g., polyethylene and polypropylene), polyesters, and polyamides, as well as regenerated fibers (e.g., rayon and cupra), and natural fibers (e.g., cotton), and mixtures of these can also be used. To enhance the flexibility of the nonwoven fabric, it is preferable that the constituent fibers be crimped fibers. The constituent fibers of the nonwoven fabric may be hydrophilic fibers (including hydrophilic fibers made hydrophilic by a hydrophilizing agent), hydrophobic fibers, or water-repellent fibers (including water-repellent fibers made water-repellent by a water-repellent agent).

[0030] Nonwoven fabrics are generally classified according to fiber length, sheet formation method, fiber bonding method, and laminate structure, into staple fiber nonwoven fabrics, long fiber nonwoven fabrics, spunbond nonwoven fabrics, meltblown nonwoven fabrics, spunlace nonwoven fabrics, thermal bond (air-through) nonwoven fabrics, needle-punched nonwoven fabrics, point-bond nonwoven fabrics, and laminated nonwoven fabrics (such as SSS (spunbond + spunbond + spunbond) nonwoven fabrics in which identical or similar nonwoven fabric layers are laminated, as well as SMS (spunbond + meltblown + spunbond) nonwoven fabrics in which a meltblown layer is sandwiched between spunbond layers, and SMMS (spunbond + meltblown + meltblown + spunbond) nonwoven fabrics in which different nonwoven fabric layers are laminated), and any of these nonwoven fabrics can be used. It is preferable that the laminated nonwoven fabric be manufactured as a single nonwoven fabric including all layers, and that all layers be subjected to a fiber bonding process. This improves the feel on the skin, and prevents irritation to the skin when it comes into contact with the skin of a pet. The laminated nonwoven fabric may be made by bonding together a plurality of separately manufactured nonwoven fabrics using a bonding means such as a hot melt adhesive.

[0031] The top sheet 2 extends from one end to the other in the front-to-rear direction D1 of the pet diaper 1, extends laterally beyond the absorbent body 4 in the width direction D2, and is joined to the waterproof sheet 3. In other embodiments, for example, when the starting points of the three-dimensional gathers 7 described below are located closer to the center in the width direction D2 than the side edges of the absorbent body 4, appropriate modifications are possible, such as making the length of the top sheet 2 in the width direction D2 shorter than the length of the absorbent body 4 in the width direction D2.

[0032] The waterproof sheet 3 is a water-impermeable sheet that does not allow excrement to pass through. A suitable example of the waterproof sheet 3 is a microporous sheet obtained by kneading an inorganic filler into an olefin resin such as polyethylene or polypropylene, forming the sheet, and then stretching it uniaxially or biaxially. Alternatively, the waterproof sheet 3 may be one that uses a nonwoven fabric as a base material to enhance waterproofing. It is desirable that the waterproof sheet 3 extend over the same area as the absorbent body 4 or over a wider area than the absorbent body 4 in the front-rear direction D1 and the width direction D2.

[0033] The absorbent body 4 is the part that absorbs and retains excretory fluid and can be formed from a fiber assembly. This fiber assembly can be made of stacked short fibers such as cotton-like pulp, synthetic fibers, and natural fibers made from softwood or hardwood, as well as filament assemblies obtained by opening tows (fiber bundles) of synthetic fibers such as cellulose acetate as needed. When stacking cotton-like pulp or short fibers, the fiber weight can be, for example, 100 to 300 g / m 2 In the case of a filament aggregate, for example, 30 to 120 g / m 2The fineness of the synthetic fibers is preferably 1 to 16 dtex, more preferably 1 to 10 dtex, and even more preferably 1 to 5 dtex. The absorbent body 4 may contain superabsorbent polymer particles in part or all of the absorbent body 4. Superabsorbent polymer particles include not only particles but also powder. The superabsorbent polymer particles may be those used in this type of absorbent article as they are. Materials for the superabsorbent polymer particles may include, for example, starch-based, cellulose-based, and synthetic polymer-based materials. The planar shape of the absorbent body 4 may be such that the central portion in the front-rear direction D1 is narrowed. In other words, the length of the absorbent body 4 in the width direction D2 may gradually decrease toward the center in the front-rear direction D1. The absorbent body 4 is arranged so as to sandwich the perforated portion 100 in the width direction D2.

[0034] The backsheet 6 covers the entire non-skin-facing side of the waterproof sheet 3, giving the outer surface of the pet diaper 1 a cloth-like appearance. A nonwoven fabric is used as the backsheet 6. The constituent fibers of the nonwoven fabric can be selected without particular limitation, for example, synthetic fibers such as olefins (e.g., polyethylene or polypropylene), polyesters, and polyamides (including single-component fibers as well as core-sheath and other composite fibers), recycled fibers (e.g., rayon or cupra), and natural fibers (e.g., cotton), or a mixture of these. Specific examples of nonwoven fabrics that can be used include spunbond nonwoven fabrics, meltblown nonwoven fabrics, spunlace nonwoven fabrics, thermal bond (air-through) nonwoven fabrics, needle-punched nonwoven fabrics, point-bond nonwoven fabrics, and laminated nonwoven fabrics (e.g., SSS (spunbond + spunbond + spunbond) nonwoven fabrics in which identical or similar nonwoven fabric layers are laminated). The fiber weight of the backsheet 6 is 10 to 50 g / m. 2 It is preferable that the density is 15 to 30 g / m 2 It is more preferable that:

[0035] The standing gathers 7 have the function of blocking bodily waste moving laterally along the top sheet 2 and preventing side leakage. Both ends of the standing gathers 7 in the front-to-back direction D1 are fixed to the top sheet 2. Specifically, as shown in Figures 2 and 4, an adhesive layer 14a is provided between both ends of the standing gathers 7 in the front-to-back direction D1 and the top sheet 2. Furthermore, the outer sides of the standing gathers 7 in the width direction D2 are fixed to the top sheet 2 over the entire length in the front-to-back direction D1. Specifically, as shown in Figures 2 to 4, an adhesive layer 14b is provided between the outer sides of the standing gathers 7 in the width direction D2 and the top sheet 2 over the entire length in the front-to-back direction D1.

[0036] The adhesive layers 14a, 14b may be made of a hot melt adhesive. In this embodiment, the adhesive layers 14a, 14b are used as the fixing means, but the fixing means is not limited to this, and any fixing means such as fusion bonding or pressure bonding may be used.

[0037] As shown in FIG. 3, the three-dimensional gathers 7 include a gathered sheet 71 and a gathered elastic member 13, which is an example of a stretchable member, and have standing ends fixed to the side edges of the absorbent body 4 by an adhesive layer 14b. The leading end of the gathered sheet 71 is folded twice along the front-to-back direction D1 of the pet diaper 1, and two gathered elastic members 13 are arranged inside this folded portion. The two gathered elastic members 13 are arranged on both sides of the absorbent body 4 in the width direction D2, extending in the front-to-back direction D1, and the three-dimensional gathers 7 can stand up by stretching in the front-to-back direction D1. The standing up of the three-dimensional gathers 7 allows them to fit closely to the pet's body surface. Note that although the illustrated example has two gathered elastic members 13, the number may be one. On the other hand, as shown in FIG. 4, both ends of the three-dimensional gathers 7 in the front-to-back direction D1 do not stand up because they are fixed by an adhesive layer 14a. In addition, the back end of the gathered elastic member 13 is located closer to the ventral side than the hole processing section 100, so that the gathered elastic member 13 is positioned closer to the ventral region F than the hole processing section 100, and is not positioned from the end of the hole processing section 100 on the ventral region F side to the back region B side.

[0038] The gathered elastic member 13 can be made of commonly used materials such as styrene rubber, olefin rubber, urethane rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicone, polyester, etc.

[0039] The gathered sheet 71 can be made of a nonwoven fabric obtained by an appropriate processing method such as the spunbond method, the air-through method, the meltblown method, or the needle punch method. In particular, the gathered sheet 71 constituting the side flap portion SF should be made of a nonwoven fabric with a low basis weight and excellent breathability to eliminate stiffness and prevent stuffiness. The material fibers constituting the gathered sheet 71 can be synthetic fibers such as olefin-based fibers such as polyethylene or polypropylene, polyester-based fibers, and amide-based fibers, as well as regenerated fibers such as rayon or cupra, and natural fibers such as cotton.

[0040] In the side flaps SF, a plurality of leg elastic members 12 (two in the illustrated example, which are an example of stretchable members) are arranged in the front-to-rear direction D1 of the pet diaper 1, forming flat gathers. These flat gathers hold the pet diaper 1 along the legs when worn, improving fit and preventing the pet diaper 1 from slipping. The leg elastic members 12 may be made of the same material as the gather elastic members 13. As shown in FIG. 2, the leg elastic members 12 are preferably arranged in the front-to-rear direction D1 at least between the fixing start end E5 on the ventral side of the upright gathers 7 and the fixing start end E6 on the dorsal side of the upright gathers 7. This allows the flat gathers to be formed in a position that includes the upright gathers 7 in the front-to-rear direction D1 of the pet diaper 1. The two leg elastic members 12 are arranged on both sides of the absorbent core 4 in the width direction D2 and stretch in the front-to-rear direction D1, thereby increasing the elastic stretchability of the upright gathers 7 and making it easier to form a urine collection space. Furthermore, the pet diaper 1 is held in place around the legs to further improve fit, thereby preventing urine leakage into the back region B. Furthermore, because the flat gathers can prevent urine leakage into the back region B, the absorber 4, which is not expected to be effective in the back region B, is not placed in the back region B, thereby reducing the manufacturing cost of the pet diaper 1. The back-side end of the leg elastic member 12 is also located more ventrally than the hole-processing portion 100, so that the leg elastic member 12 is located closer to the ventral region F than the hole-processing portion 100, and is not located between the end of the hole-processing portion 100 on the ventral region F side and the back region B side.

[0041] The connecting tape 8 has a tape substrate 81 made of plastic, polylaminated nonwoven fabric, nonwoven fabric, paper, or the like, and the base of the tape substrate 81 is joined to the side flap SF. The protruding piece of the tape substrate 81 has a hook member 82 on the skin-facing surface (the surface facing the top sheet 2). The hook member 82 is non-removably adhered to the tape substrate 81 with an adhesive, and has a number of engaging pieces. In the product state, the connecting tape 8 is folded toward the top sheet 2, and the hook member 82 is removably joined to the gathered sheet 71.

[0042] The distance between the ventral end E4 of the waist sheet 9 and the ventral end E1 of the pet diaper 1 is 0 mm to 5 mm, the distance between the ventral end E3 of the absorber 4 and the ventral end E1 of the pet diaper 1 is 15 mm to 35 mm, and the distance between the ventral fixing start end E5 of the upright gathers 7 and the ventral end E3 of the absorber 4 is 0 mm to 5 mm. Here, "distance" refers to the shortest distance in the front-to-rear direction D1. As a result, the absorber 4 extends, on the ventral side of the pet diaper 1, at least to the area facing the urination opening when the pet diaper 1 is worn by a male pet.

[0043] The waist sheet 9 includes a first region R1 that overlaps a portion of the ventral side of the absorbent body 4, and a second region R2 that extends further ventrally and outward in the width direction D2 than the first region R1 and does not overlap with the absorbent body 4, the second region R2 elastically stretching in the width direction D2, and the first region R1 not elastically stretching on the absorbent body 4 in the width direction D2.

[0044] With this configuration, when a male pet wears the pet diaper 1, the second region R2 of the waist sheet 9 elastically stretches, causing the end of the absorber 4 in the width direction D2 to contract inward and fit snugly against the male pet's abdomen. On the other hand, the first region R1 that overlaps with the absorber 4 does not elastically stretch on the absorber 4, so the absorber 4 located in the first region R1 does not fit snugly against the male pet's abdomen and is in a loose state. At the same time, the three-dimensional gathers 7 rise from a position within 5 mm of the abdominal end E3 of the absorber 4, and the contractile force of the three-dimensional gathers 7 in the front-to-back direction D1 acts on the absorber 4 located in the first region R1.

[0045] The absorber 4 forms a deformed protrusion (not shown) that protrudes from the abdominal end toward the non-skin facing side, separating it from the male pet's abdomen. As a result, in the pet diaper 1, the absorber 4 forms a urine collection space that surrounds the front and periphery of the male pet's urination opening at a distance. Therefore, the pet diaper 1 can sufficiently collect urine with the absorber 4, and can prevent urine from leaking to the outside. Furthermore, because the urination opening and the absorber 4 are separated, urine absorbed by the absorber can be prevented from coming into contact with and adhering to the urination opening.

[0046] It is preferable that the distance between the fixing start end E5 on the ventral side of the upright gathers 7 and the ventral end E3 of the absorbent body 4 is 0 mm. Here, the distance of 0 mm between the fixing start end E5 on the ventral side of the upright gathers 7 and the ventral end E3 of the absorbent body 4 means that the distance between the fixing start end E5 and the ventral end (front end) E1 of the pet diaper 1 is the same as the distance between the ventral end E3 of the absorbent body 4 and the ventral end E1 of the pet diaper 1.

[0047] As a result, when a male pet wears the pet diaper 1, a deformed protrusion is formed that protrudes from the ventral end E3 of the absorber 4 toward the non-skin facing side, forming a urine collection space further forward and allowing the absorber 4 to be effectively used to collect urine from the ventral end E3. Therefore, the pet diaper 1 can more sufficiently collect urine with the absorber and more effectively prevent urine from leaking to the outside.

[0048] The first region R1 and the second region R2 of the waist sheet 9 may include elastic members 91 that are stretchable in the width direction D2. Specifically, as shown in FIG. 4, the waist sheet 9 may include two nonwoven fabric sheets 92 and an elastic member 91 that is stretchable in the width direction D2 and disposed between the two nonwoven fabric sheets 92. In this case, the elastic member 91 in the first region R1 is cut. As a result, by providing elastic members in the first region R1 and the second region R2 of the waist sheet 9 and then cutting the elastic member fixed to the first region R1 that overlaps with the absorbent body 4 with a shirring cutter or the like, the second region R2 can be configured to elastically stretch in the width direction, while the first region R1 that overlaps with the absorbent body 4 cannot elastically stretch in the width direction on the absorbent body 4. With this configuration, the absorbent body 4 forms a protruding portion that protrudes from the ventral end toward the non-skin-facing side and deforms, and in the pet diaper 1, the absorbent body 4 forms a urine collection space that surrounds the front and periphery of the male pet's urination opening at a distance. Therefore, the pet diaper 1 can sufficiently capture urine with the absorbent body, and can prevent urine from leaking to the outside.

[0049] The second region R2 of the waist sheet 9 may include an elastic member 91 that is elastically stretchable in the width direction D2, while the first region R1 may include an elastic member 91 that is elastically stretchable in the width direction D2 only in a portion of the back-side edge. By providing the elastic member 91 in the second region R2 of the waist sheet 9, the second region R2 is elastically stretchable in the width direction D2, and the first region R1 that overlaps with the absorber 4 includes the elastic member 91 only in a portion of the back side, resulting in a configuration in which the contractile force is small and the absorber 4 does not elastically stretch in the width direction D2. As a result, the absorber 4 forms a deformed protrusion that protrudes from the ventral edge toward the non-skin-facing side, and in the pet diaper 1, the absorber 4 forms a urine collection space that surrounds the front and periphery of the male pet's urination opening at a distance. As a result, the pet diaper 1 can adequately collect urine with the absorber 4 and prevent urine from leaking to the outside.

[0050] Examples of the elastic member 91 include rubber thread, stretchable film, or a member formed by bonding these with nonwoven fabric, etc. Materials that can be used to form the elastic member 91 include commonly used styrene rubber, olefin rubber, urethane rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicone, polyester, etc.

[0051] The tension of the elastic member 91 is preferably 2.0 cN to 10.0 cN. By setting the tension of the elastic member 91 to 2.0 cN to 10.0 cN, when a male pet wears the pet diaper 1, the protruding portion protruding toward the non-skin facing side can be made to a sufficient height, and the absorber 4 can be sufficiently spaced from the male pet's abdomen. This allows a sufficiently large urine collection space to be formed in the pet diaper 1, and the pet diaper 1 can further prevent urine from leaking to the outside.

[0052] Alternatively, the second region R2 of the waist sheet 9 may include an elastic member 91 that is elastically stretchable in the width direction D2, while the first region R1 does not include the elastic member 91. By providing the elastic member 91 only in the second region R2 of the waist sheet 9, the second region R2 can be elastically stretchable in the width direction D2, while the first region R1 that overlaps the absorber 4 does not elastically stretch in the width direction D2 on the absorber 4. With this configuration, the absorber 4 forms a protruding portion that protrudes from the ventral end toward the non-skin-facing side, and in the pet diaper 1, the absorber 4 forms a urine collection space that surrounds the front and periphery of the male pet's urination opening at a distance. Therefore, the pet diaper 1 can adequately collect urine with the absorber and prevent urine from leaking to the outside.

[0053] Furthermore, the waist sheet 9 may not include the elastic member 91 and may be a sheet-like elastic member such as a rubber sheet that is elastically stretchable in the width direction D2.

[0054] (Hole processing section 100) The buttocks covering region M of the pet diaper 1 is provided with the perforated portion 100 as described above.

[0055] 5A and 5B are diagrams showing the detailed configuration of the hole processing unit 100 shown in FIG. 1, in which (a) is a diagram showing the overall configuration, (b) is a diagram showing the configuration in the vicinity of the vertex 111c of the slit 111, and (c) is a diagram showing the configuration in the vicinity of the end 125a of the perforation 122a. 5, the hole processing unit 100 in this embodiment has a first hole forming unit 110 and a second hole forming unit 120. The hole forming unit 110 is for forming a first hole, which will be described later. The hole forming unit 120 is continuous with the back side of the hole forming unit 110 and is for forming a second hole, which will be described later.

[0056] The hole forming portion 110 has a slit 111 .

[0057] The slit 111 penetrates the back sheet 6, the waterproof sheet 3, and the top sheet 2, and has a V-shaped bend at a rounded apex 111c. In other words, in the present application, a shape with a rounded apex is also defined as a V-shape. The radius r1 of the apex 111c is preferably 10 mm or less, and the angle d2 of the apex 111c is preferably 90 degrees to 150 degrees. The inner angle d4 of the apex 111c is d4≦180°-d2 It is preferable that:

[0058] Furthermore, it is preferable that the length L2 of the slit 111 from the vertex 111c to both end portions 111a and 111b is 10 mm to 60 mm. For example, the length L2 from the vertex 111c to both end portions 111a and 111b may be 28 mm. It is also preferable that the length L3 from the vertex 111c to both end portions 111a and 111b in the direction of the bisector of the vertex 111c is 10 mm to 50 mm. For example, the length L3 from the vertex 111c to both end portions 111a and 111b in the direction of the bisector of the vertex 111c may be 26 mm. It is also preferable that the distance L4 between both end portions 111a and 111b is 5 mm to 70 mm. For example, the distance L4 between both end portions 111a and 111b may be 33 mm. The apex 111c of the slit 111 faces the abdominal region F, and thus the slit 111 has a convex shape that faces the abdominal side of a pet wearing the pet diaper 1.

[0059] The hole forming portion 120 has two perforations 122a and 122b.

[0060] The perforation 122a is connected to one end 111a of the slit 111 and extends from there in a line extending from the slit 111. Therefore, the perforation 122a extends from one end 111a of the slit 111 toward the back of a pet wearing the pet diaper 1. The perforation 122a is configured by alternately arranging cut portions 123a and tie portions 124a. The alternately arranging pitch of the cut portions 123a and tie portions 124a is preferably approximately 0.5 mm to 3 mm, and more preferably approximately 1 mm to 2 mm. For example, the length of the cut portions 123a may be 3.5 mm, and the length of the tie portions 124a may be 1.5 mm. The cut portions 123a penetrate the back sheet 6, the waterproof sheet 3, and the top sheet 2. The perforation 122a configured in this manner preferably has three or more cut portions 123a. The perforation 122a has an end 125a opposite the slit 111 that is rounded by being curved toward the inside of the hole processing portion 100. In this case, the end 125a of the perforation 122a opposite the slit 111 is composed of a part of an arc having a center inside the hole processing portion 100, and the radius r2 of the end 125a is preferably 10 mm or less, and the angle d3 of the end 125a is preferably 30 degrees to 270 degrees. Furthermore, as shown in FIG. 5, the end 125a of the perforation 122a may be further curved toward the outside of the hole processing portion 100. In this case, the end 125a of the perforation 122a opposite the slit 111 will have a portion of an arc having a center outside the hole processing section 100 continuing from the portion curved inward of the hole processing section 100 as described above, and in this case, the curvature radius r3 is preferably 10 mm or less, the same as the radius r2, and the angle d5 is preferably 30 degrees to 270 degrees.

[0061] The perforation 122b is connected to one end 111b of the slit 111 and extends from there in a line extending from the slit 111. Therefore, the perforation 122b extends from one end 111a of the slit 111 toward the back of a pet wearing the pet diaper 1. The perforation 122b is configured by alternately arranging cut portions 123b and tie portions 124b. The alternately arranging pitch of the cut portions 123b and tie portions 124b is preferably approximately 0.5 mm to 3 mm, and more preferably approximately 1 mm to 2 mm. For example, the length of the cut portions 123b may be 3.5 mm, and the length of the tie portions 124b may be 1.5 mm. The cut portions 123b penetrate the back sheet 6, the waterproof sheet 3, and the top sheet 2. The perforation 122b configured in this manner preferably has three or more cut portions 123b. The perforation 122b has a rounded end 125b opposite the slit 111 curved inward of the hole processing portion 100. In this case, the end 125b of the perforation 122b opposite the slit 111 is composed of a part of an arc having a center inside the hole processing portion 100, and the radius of the end 125b is preferably 10 mm or less, and the angle of the end 125b is preferably 30 degrees to 270 degrees. Furthermore, the end 125b of the perforation 122b may further curve outward from the hole processing portion 100. In this case, the end 125b of the perforation 122b opposite the slit 111 has a part of an arc having a center outside the hole processing portion 100 connected to the part curved inward of the hole processing portion 100 as described above.

[0062] In this way, each of the perforations 122a and 122b extends on an extension of the V-shaped slit 111. As a result, the two perforations 122a and 122b are formed so that the distance between them increases as they move away from the slit 111.

[0063] The hole processing portion 100 configured in this manner preferably has a length L5 of 15 mm to 80 mm in the front-rear direction D1 of the pet diaper 1 and a length L6 of 6 mm to 120 mm in the width direction D2. For example, both the length L5 in the front-rear direction D1 and the length L6 in the width direction D2 may be 45 mm.

[0064] As a combination of the above-mentioned sizes, for example, the angle d2 of the vertex 111c of the slit 111 may be 120 degrees, the length L3 from the vertex 111c of the slit 111 to both end portions 111a, 111b in the direction of the bisector of the vertex 111c may be 10 mm, the spacing L4 between both end portions 111a, 111b of the slit 111 may be 12.55 mm, the inner angle d4 of the vertex 111c of the slit 111 may be 47 degrees, the angle d3 of the ends 125a, 125b of the perforations 122a, 122b may be 135 degrees, the length L5 of the hole processing portion 100 in the front-to-rear direction D1 may be 28 mm, and the length L6 in the width direction D2 may be 25 mm. Furthermore, if the ends 125a, 125b of the perforations 122a, 122b have a rounded pattern that is curved outward from the hole processing section 100, the angle d5 may be set to 40 degrees.

[0065] Alternatively, the angle d2 of the vertex 111c of the slit 111 may be 120 degrees, the length L3 from the vertex 111c of the slit 111 to both ends 111a, 111b in the direction of the bisector of the vertex 111c may be 13 mm, the spacing L4 between both ends 111a, 111b of the slit 111 may be 13.97 mm, the inner angle d4 of the vertex 111c of the slit 111 may be 42 degrees, the angle d3 of the ends 125a, 125b of the perforations 122a, 122b may be 135 degrees, the length L5 of the hole processing portion 100 in the front-to-rear direction D1 may be 31 mm, and the length L6 of the width direction D2 may be 25 mm. If the ends 125a, 125b of the perforations 122a, 122b are further rounded and curved outward from the hole processing portion 100, the angle d5 may be 40 degrees.

[0066] Alternatively, the angle d2 of the vertex 111c of the slit 111 may be 120 degrees, the length L3 from the vertex 111c of the slit 111 to both ends 111a, 111b in the direction of the bisector of the vertex 111c may be 15 mm, the spacing L4 between both ends 111a, 111b of the slit 111 may be 18.7 mm, the angle d4 inside the vertex 111c of the slit 111 may be 53 degrees, the angle d3 of the ends 125a, 125b of the perforations 122a, 122b may be 140 degrees, the length L5 of the hole processing portion 100 in the front-to-rear direction D1 may be 38 mm, and the length L6 in the width direction D2 may be 38 mm. If the ends 125a, 125b of the perforations 122a, 122b are further rounded and curved outward from the hole processing portion 100, the angle d5 may be 40 degrees.

[0067] Alternatively, the angle d2 of the vertex 111c of the slit 111 may be 120 degrees, the length L3 from the vertex 111c of the slit 111 to both ends 111a, 111b in the direction of the bisector of the vertex 111c may be 17 mm, the spacing L4 between both ends 111a, 111b of the slit 111 may be 20.7 mm, the inner angle d4 of the vertex 111c of the slit 111 may be 53 degrees, the angle d3 of the ends 125a, 125b of the perforations 122a, 122b may be 140 degrees, the length L5 of the hole processing portion 100 in the front-to-rear direction D1 may be 42 mm, and the length L6 of the width direction D2 may be 42 mm. If the ends 125a, 125b of the perforations 122a, 122b are further rounded and curved outward from the hole processing portion 100, the angle d5 may be 40 degrees.

[0068] Alternatively, the angle d2 of the vertex 111c of the slit 111 may be 120 degrees, the length L3 from the vertex 111c of the slit 111 to both ends 111a, 111b in the direction of the bisector of the vertex 111c may be 19 mm, the spacing L4 between both ends 111a, 111b of the slit 111 may be 22.7 mm, the inner angle d4 of the vertex 111c of the slit 111 may be 53 degrees, the angle d3 of the ends 125a, 125b of the perforations 122a, 122b may be 140 degrees, the length L5 of the hole processing portion 100 in the front-to-rear direction D1 may be 46 mm, and the length L6 of the width direction D2 may be 46 mm.

[0069] (How to use pet diaper 1) FIG. 6 is a diagram showing the wearing style of the pet diaper 1 shown in FIG. 1, and FIG. 7 is a diagram for explaining the function of the hole-processed portion 100 in the wearing style shown in FIG.

[0070] First, a method of use for keeping feces inside the pet diaper 1 will be described.

[0071] When the pet diaper 1 shown in FIG. 1 is to be put on, for example, a dog 20 as shown in FIG. 6(a), first, in the state shown in FIG. 1, the central portion of the ventral region F in the width direction D2 is placed against the belly of the dog 20, and the pet diaper 1 is positioned so that the two legs 20b of the dog 20 straddle the buttocks-covering region M. At this time, the perforations 122a, 122b of the hole forming portion 120 are not torn, and are oriented so that the skin surface is in contact with the dog 20. However, when the pet diaper 1 is to be put on a dog with a thick tail, it is preferable to tear the perforations 122a, 122b by an appropriate width to fit the dog, and adjust them so that the tail can pass through not only the first hole 117 described below but also part of the second hole 127 connected to it.

[0072] Next, the dorsal region R is lifted up and folded back so that the skin side faces inward at the buttocks covering region M. Then, as shown in FIG. 7(a), the flap portion 116 formed by the V-shaped slit 111 of the hole forming portion 110 is rolled up to form a first hole 117, and the tail 20c of the dog 20 is passed through the hole 117, and the dorsal region R is brought into contact with the back of the dog 20.

[0073] Then, both ends of the ventral region F in the width direction D2 are lifted, and the ventral region F is brought into contact with the dorsal region R so as to encase the belly of the dog 20. As a result, the torso 20a of the dog 20 is passed through the waist opening WO formed by the ventral region F and the dorsal region R, and the legs 20b of the dog 20 are passed through a pair of leg openings LO formed by the narrowed portions of the ventral region F and the dorsal region B in the width direction D2 and the buttocks covering region M.

[0074] Connecting tapes 8 are attached to both ends of the ventral region F in the width direction D2, and target tapes 11 are attached to the dorsal region R of the backsheet 6. Therefore, by joining the connecting tapes 8 and the target tapes 11, the pet diaper 1 can be put on the dog 20. At this time, the target tapes 11 are attached over the entire area of ​​the backsheet 6 in the width direction D2. This allows the connecting tapes 8 to be joined at any position in the width direction D2 of the dorsal region R, and the waist opening WO can be easily adjusted according to the pet's waist size.

[0075] 1, the dog 20 can expose its tail 20c through the hole 117. Furthermore, since only the tail 20c can be exposed through the hole 117 and the anus 20e of the dog 20 is not exposed through the hole 117, feces can be contained inside the pet diaper 1.

[0076] Next, a method of use when the feces are to be expelled from the pet diaper 1 will be described.

[0077] When the pet diaper 1 shown in FIG. 1 is to be put on, for example, a dog 20 as shown in FIG. 6(b), first, in the state shown in FIG. 1, the central portion of the ventral region F in the width direction D2 is placed against the belly of the dog 20, and the pet diaper 1 is positioned so that the two legs 20b of the dog 20 straddle the buttocks-covering region M. At this time, the perforations 122a, 122b of the hole-forming portion 120 are broken, and the skin surface is oriented to come into contact with the dog 20. The width at which the perforations 122a, 122b are broken may be adjusted to match the body shape and thickness of the tail 20c of the dog 20 wearing the pet diaper 1 so that the anus 20e is exposed through the hole 117. Here, if an attempt is made to tear all of the perforations 122a, 122b, if the tearing force is strong, there is a risk that the ends of the perforations 122a, 122b opposite the slit 111 will tear. Here, as shown in FIG. 5, the ends 125a, 125b of the perforations 122a, 122b opposite the slit 111 are rounded and curved. Therefore, at the ends 125a, 125b of the perforations 122a, 122b opposite the slit 111, the direction in which the perforations 122a, 122b move is different from the direction in which the force attempting to tear the perforations 122a, 122b is applied. This makes it possible to prevent the ends of the perforations 122a, 122b from tearing when the perforations 122a, 122b are torn.

[0078] Next, the dorsal region R is lifted up and folded back so that the skin side faces inward at the buttocks covering region M. Then, as shown in FIG. 7(b), the flap portion 116 formed by tearing the V-shaped slit 111 of the hole forming portion 110 and the perforations 122a, 122b of the hole forming portion 120 is rolled up, thereby forming a first hole 117 and a second hole 127 continuous with this hole 117 on the dorsal region B side. Then, by adjusting the position of the pet diaper 1 in the front-to-rear direction D1 so that the tail 20c of the dog 20 protrudes through the hole 127, the anus 20e of the dog 20 is exposed through the hole 117, and the dorsal region R is brought into contact with the back of the dog 20.

[0079] Then, both ends of the ventral region F in the width direction D2 are lifted, and the ventral region F is brought into contact with the dorsal region R so as to encase the belly of the dog 20. As a result, the torso 20a of the dog 20 is passed through the waist opening WO formed by the ventral region F and the dorsal region R, and the legs 20b of the dog 20 are passed through a pair of leg openings LO formed by the narrowed portions of the ventral region F and the dorsal region B in the width direction D2 and the buttocks covering region M.

[0080] Then, by joining the connecting tape 8 and the target tape 11, the pet diaper 1 can be put on the dog 20.

[0081] In this manner, by having the dog 20 wear the pet diaper 1 shown in Fig. 1, the tail 20c can be exposed to the outside through the hole 127. Furthermore, the anus 20e of the dog 20 is exposed through the hole 117, allowing the feces to be exposed to the outside of the pet diaper 1. Even when the feces are to be allowed to pass through the pet diaper 1, rather than tearing all of the perforations 122a, 122b, the amount of tearing of the perforations 122a, 122b may be adjusted depending on the thickness of the tail of the pet wearing the pet diaper 1 and the distance between the tail and the anus.

[0082] In this way, by not forming hole 127 when the feces are to be kept out, and by forming hole 127 when the feces are to be let out, it is possible to choose between keeping the feces inside or letting them out while still allowing tail 20c to be let out. Also, by adjusting the width at which perforations 122a and 122b are broken, it is possible to accommodate a wide variety of dog tails.

[0083] In this embodiment, the hole processing section 100 is positioned so that the length L1 from the ventral end E1 of the pet diaper 1 to the end of the hole processing section 100 on the ventral region F side is 50% to 75% of the length L0 in the front-to-rear direction D1 from the ventral end E1 to the dorsal end E2 of the pet diaper 1. This makes it easier to choose between keeping the feces inside or letting them out, while still allowing the tail to be let out using the hole processing section 100.

[0084] Furthermore, in this embodiment, the gathered elastic members 13 and the leg elastic members 12 are positioned closer to the ventral region F than the hole processing section 100, and are not positioned from the end of the hole processing section 100 on the ventral region F side to the dorsal region B side. This prevents holes 117, 127 from shrinking in the front-to-back direction D1 when passing the tail through hole 117 formed by hole forming section 110 or hole 127 formed by hole forming section 120, making it difficult to pass the tail through.

[0085] As described above, the pet diaper 1 of this embodiment is formed so that the two perforations 122a, 122b that make up the hole formation section 120 are spaced apart more widely as they move away from the slit 111 that makes up the hole formation section 110. Therefore, as the area where the perforations 122a, 122b are broken becomes larger, the hole 127 can be widened in the width direction D2 of the pet diaper 1, making it easier to accommodate thick tails.

[0086] As described above, the apex 111c of the V-shape of the slit 111 in this embodiment faces the abdominal region F, thereby forming a convex shape toward the abdominal side of the pet wearing the diaper 1. The V-shape of the slit 111 causes the apex of the triangle of the hole 117 to be positioned on the pet's urination opening 2d side, and the sharp end of the hole 117 on the urination opening 2d side thereby prevents urine leakage.

[0087] As described above, the absorbent body 4 in this embodiment is arranged so as to sandwich the hole processing portion 100 in the width direction D2. This prevents urine from leaking laterally when the pet is bedridden, for example.

[0088] (Another embodiment of the hole processing part) FIG. 8 is a diagram showing another embodiment of the hole processing portion.

[0089] 8(a), the hole processing section of the present invention may be a hole processing section 200 having a first hole forming section 210 consisting of a V-shaped slit 211 and a second hole forming section 220 consisting of two perforations 222a, 222b. The perforations 222a, 222b extend from both ends of the slit 211 in the front-to-rear direction D1 of the pet diaper toward the side opposite to the side toward which the apex of the V-shape faces.

[0090] 8(b), the hole processing section of the present invention may be a hole processing section 300 having a first hole forming section 310 consisting of a U-shaped slit 311 and a second hole forming section 320 consisting of two perforations 322a, 322b. The perforations 322a, 322b extend from both ends of the slit 311 toward the side opposite the U-shaped protruding side in the front-to-rear direction D1 of the pet diaper.

[0091] 8(c), the hole processing section of the present invention may be a hole processing section 400 having a first hole forming section 410 composed of a U-shaped slit 411 and a second hole forming section 420 composed of two perforations 422a, 422b. Note that the perforations 422a, 422b are formed so that the spacing between them increases as they move away from the slit 411 from both ends of the slit 411 toward the side opposite the U-shaped protruding side.

[0092] Furthermore, as shown in Fig. 8(d), the hole processing portion of the present invention may have a configuration including, in addition to slit 511 identical to slit 111 shown in Fig. 5 and perforations 522a and 522b identical to perforations 122a and 122b shown in Fig. 5, perforation 522c connecting the ends of perforations 522a and 522b opposite slit 511, and perforation 522d extending in the front-to-rear direction D1 of the pet diaper between perforations 522a and 522b. In such a configuration, perforation 522d is torn and perforation 522c is torn from the portion where it intersects with perforation 522d by an amount corresponding to the size of the tail to form two flaps that can be rolled up. Then, by rolling up these two flaps so as to open them up, a hole for the tail to pass through is formed, and by rolling up the flap formed by the slit 511, a hole for the feces to pass out of the pet diaper is formed. This makes it possible to insert the tail while also making it easy for the feces to pass out of the pet diaper.

[0093] In the above-described embodiment, the pet diaper 1 shown in Fig. 1 is described as being worn by a dog 20. However, the pet diaper 1 shown in Fig. 1 is not limited to dogs, but can also be worn by cats or small animals with tails such as dogs and cats. [Explanation of symbols]
