A first cutout portion forming a first opening portion through which a tail of the pet can pass, and a second cutout portion having an area larger than that of the first opening portion, forming a second opening portion through which excrement of the pet can pass, are formed in the main body portion, and at least a portion of the first cutout portion and the second cutout portion are disposed on an outer surface of the folded main body portion.

Description

Technical Field

[0001] This disclosure relates to pet diapers. Background Technology

[0002] Pet diapers for dogs, cats, and other pets are known. For example, Patent Document 1 describes a pet diaper that includes: a first slit forming a first tail hole; a second slit positioned between the first slit and an absorbent core, forming a second tail hole; and an easy-cut portion extending between the first and second slits. When this pet diaper is worn on a male dog, the absorbent core is positioned in front of the base of the hind leg by passing the tail through the first tail hole. Conversely, when this pet diaper is worn on a female dog, the absorbent core is positioned near the base of the hind leg by passing the tail through the second tail hole. Thus, in the pet diaper described in Patent Document 1, by selecting the tail hole through which the tail passes according to the dog's sex and positioning the absorbent core at a position covering the dog's urination opening, leakage can be reduced.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2012-205542 Summary of the Invention

[0006] The problem the invention aims to solve

[0007] However, whether a pet's feces should be discharged into the inside or outside of the diaper depends on the user's preference and the situation. For example, when the pet is indoors, it is preferable for the pet to discharge into the inside of the diaper to avoid soiling the room, while when the pet is outdoors, it is preferable for the pet to discharge into the outside of the diaper to avoid the feces sticking to the pet's fur.

[0008] Therefore, in order to allow users to choose whether their pet defecates inside or outside the diaper, the idea was to create two openings of different sizes in the pet diaper. However, even with two openings in the pet diaper, if the user does not notice their presence, they will not be able to identify the option to choose where to defecate.

[0009] Therefore, this disclosure is intended to make it easy for the user to identify whether the pet can choose to defecate inside or outside the diaper.

[0010] Solution for solving the problem

[0011] In one technical solution, a pet diaper is provided that is housed in a folded state within a packaging body. The pet diaper has a longitudinal direction extending from the pet's ventral side to its dorsal side and a width direction perpendicular to the longitudinal direction. It includes a main body portion comprising a surface sheet, a back sheet, and an absorbent core disposed between the surface sheet and the back sheet. The main body portion has: a first slit portion forming a first opening through which the pet's tail can pass; and a second slit portion having an area larger than the first opening portion, forming a second opening through which the pet's feces can pass. At least partially, the first and second slit portions are disposed on the outer surface of the folded main body portion.

[0012] In the pet diaper of this technical solution, at least partially, a first slit for forming a first opening through which the pet's tail can pass and a second slit for forming a second opening through which the pet's feces can pass are disposed on the outer surface of the folded main body. Therefore, when the pet diaper is removed from the packaging, the user can visually identify the first and second slits. As a result, the user can identify whether the pet can choose to defecate inside or outside the diaper.

[0013] In one embodiment, the pet diaper may be folded in three or four folds along its longitudinal direction, with the first and second slits integrally disposed on the outer surface of the folded main body. By having the first and second slits integrally disposed on the outer surface of the folded main body, the user can more easily identify the available defecation site.

[0014] In one embodiment, the main body may include a non-cut portion disposed between the first and second cut portions. When the non-cut portion breaks, connecting the first and second cut portions, the second cut portion, together with the first cut portion, forms a second opening that includes the first opening portion. In this embodiment, when the non-cut portion breaks, the second opening is formed, and the pet's feces are discharged to the outside of the diaper. On the other hand, when the non-cut portion does not break, the second opening is not formed, and therefore, the pet's feces are discharged to the inside of the diaper. Thus, it is possible to select whether the pet defecates inside or outside the diaper.

[0015] In one embodiment, the first cut may be formed on the back side of the main body, closer to the absorbent core, and the second cut may be formed on the back side of the main body, closer to the first cut. In this embodiment, by breaking the non-cut portion, the opening formed in the main body can be enlarged towards the back side.

[0016] In one embodiment, the first cut may be configured as a wing-shaped tongue that forms part of both the surface and back sheet. When the tongue is pulled towards the back side, the non-cut portion breaks, and the first cut portion connects to the second cut portion. In this embodiment, the second opening can be easily formed by pulling the tongue towards the back side. Furthermore, since the second opening is formed by pulling the tongue in the opposite direction to the absorbent core, it is possible to prevent the absorbent core from being accidentally broken when the non-cut portion breaks.

[0017] In one embodiment, the first incision may include a U-shaped slit protruding ventrally, and the second incision may include a pair of slits adjacent to a pair of ends of the U-shaped slit via a non-incision portion. In this embodiment, the pair of ends of the U-shaped slit are connected to the pair of slits by breaking the non-incision portion, thus forming the second opening.

[0018] In one embodiment, the pair of slits may extend in a straight line, moving further apart from each other as they face the dorsal side. In this embodiment, when the tongue is pulled towards the dorsal side and the non-cut portion breaks, the force is distributed in the width direction of the pet diaper, thus making it difficult to accidentally tear the main body towards the dorsal side when forming the second opening.

[0019] In one embodiment, the first cut may include an annular slit extending over the entire circumference of the end edge of the first opening. Because of the annular slit, portions of the surface and back panels are partially cut, thus making the presence of the first opening easily identifiable to the user.

[0020] In one embodiment, the first incision may be formed on the dorsal side of the main body, closer to the absorbent core, and the second incision may be formed longitudinally between the first incision and the absorbent core. In this embodiment, when the second opening is formed by breaking the non-incision portion, the opening extends ventrally, thus the position of the dorsal edge of the opening does not change. That is, the positional relationship between the pet's tail and the pet diaper does not change, therefore, it is difficult for the pet diaper to deviate. As a result, leakage can be suppressed.

[0021] In one embodiment, the first incision may be configured as a wing-shaped tongue that forms part of the surface and back plates. When the tongue is pulled ventrally, the non-incision portion breaks off, and the first incision portion connects with the second incision portion. In this embodiment, the second opening can be formed by simply cutting off the non-incision portion by pulling the tongue ventrally.

[0022] In one embodiment, the first incision may include a U-shaped slit protruding toward the dorsal side, and the second incision may include a pair of slits adjacent to a pair of ends of the U-shaped slit via a non-incision portion. In this embodiment, the pair of ends of the U-shaped slit are connected to the pair of slits by cutting off the non-incision portion, forming the second opening.

[0023] In one embodiment, the pair of slits may extend in a straight line, moving away from each other as they move toward the ventral side. In this embodiment, when the tongue is pulled toward the ventral side to break the non-cut portion, the force is distributed in the width direction of the pet diaper, thus preventing the absorbent core from being accidentally torn when the second opening is formed.

[0024] In one embodiment, the first cut may include an annular slit extending over the entire circumference of the end edge of the first opening. Because of the annular slit, portions of the surface and back panels are partially cut, thus making the presence of the first opening easily identifiable to the user.

[0025] Alternatively, one embodiment of the pet diaper may further include: a pair of fastening tabs extending outward in the width direction of the main body; and a target portion positioned on the dorsal side of the main body closer to the pair of fastening tabs, engaging with the pair of fastening tabs; the dorsal edge of the second opening is positioned on the ventral side closer to the midline between the centerline of the main body in the longitudinal direction and the ventral edge of the target portion. By positioning the dorsal edge of the second opening in such a position, when the pet diaper is worn, the dorsal edge of the second opening can reliably abut against the back of the pet's tail. This suppresses deviation of the pet diaper. As a result, leakage of urine is prevented, and feces are discharged to the outside of the pet diaper.

[0026] In one embodiment, the area of ​​the second opening may be more than twice the area of ​​the first opening. By setting the area of ​​the second opening to more than twice the area of ​​the first opening, the pet's feces can be reliably discharged to the outside of the pet diaper.

[0027] In one embodiment, the maximum length of the second opening in the longitudinal direction may be more than twice the maximum length of the first opening in the longitudinal direction. By setting the length of the second opening in the longitudinal direction to more than twice the length of the first opening in the longitudinal direction, the pet's feces can be reliably discharged to the outside of the pet diaper.

[0028] In one embodiment, the maximum width of the first opening in the width direction may be greater than the maximum length of the first opening in the longitudinal direction. By making the first opening horizontally elongated, the pet's tail can easily pass through the first opening.

[0029] In one embodiment, the maximum length of the second opening in the longitudinal direction may be greater than the maximum width of the second opening in the width direction. By making the second opening a longitudinally elongated shape, it is easier for pet feces to pass through.

[0030] Alternatively, one embodiment of the pet diaper also includes an elastic member fixed to the main body in a longitudinally elongated state and extending longitudinally across the second opening. As the elastic member contracts longitudinally, the area between the second opening of the main body and the absorbent core is pulled and pressed against the pet's buttocks. This improves the fit of the pet diaper, making it difficult for gaps to form between the edge of the second opening and the pet's buttocks. Therefore, the pet's feces can be reliably discharged to the outside of the pet diaper.

[0031] In one embodiment, a design pattern may be applied to the surface of the back sheet, but not to the surface of the front sheet. In this embodiment, the front sheet without a design pattern can be visually identified through the first opening, thus making it easy for the user to recognize the presence of the first opening based on the difference in contrast.

[0047] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. Furthermore, in the following description, the same reference numerals will be used to designate the same elements or equivalent elements, and descriptions will not be repeated. The scale of the drawings may not necessarily match the scale of the description.

[0048] Figure 1 This is a top view of one embodiment of a pet diaper, viewed from the skin side (Z1). Figure 2 It is along Figure 1 The schematic diagram shown by line II-II represents a cross-sectional view of a pet diaper. Figure 1 In this context, "pet diaper 1" refers to the pet diaper 1 in its stretched state, where it is no longer wrinkled. Unless otherwise specified, the positional relationships in the stretched state will be described in the following description. Furthermore, in... Figure 2 In the sectional view shown, for ease of explanation, the components are shown separately in the thickness direction Z, but in the actual product, the components are in contact in the thickness direction Z.

[0049] Pet diaper 1 is a diaper used for pets. In this specification, "pet" broadly includes vertebrates and invertebrates, typically including pet animals such as dogs, cats, rabbits, and hamsters. The pet diaper 1 of one embodiment is particularly suitable for use as a diaper for small animals such as puppies, small dogs, and cats. Figure 1As shown, the pet diaper 1 extends in a width direction X, which is arranged along the pet's waist, and in a longitudinal direction Y, which connects the pet's abdomen to its back. The width direction X and the longitudinal direction Y are perpendicular to each other. The thickness direction Z is perpendicular to both the width direction X and the longitudinal direction Y, including the skin-side Z1 facing the pet's skin when worn and the non-skin-side Z2 facing the side opposite to the pet's skin when worn. Figure 4 As shown, the pet diaper 1 is worn by covering the pet's abdomen from the crotch to the back.

[0050] The pet diaper 1 has a main body 2. The main body 2 extends in the width direction X and the longitudinal direction Y. Furthermore, in the following description, one end of the main body 2 in the longitudinal direction Y is sometimes referred to as the ventral side, and the other end in the longitudinal direction Y is sometimes referred to as the dorsal side. Figure 1 and Figure 2 As shown, the main body 2 includes a surface sheet 10, a back sheet 20, and an absorbent core 30. The surface sheet 10 forms the surface that contacts the pet in the main body 2 and is disposed on the skin side Z1. The surface sheet 10 has permeability, allowing the pet's urine to pass through to the absorbent core 30. The surface sheet 10 includes: a center sheet 11 located at the center in the width direction X, covering the absorbent core 30; and a pair of side sheets 12 covering the two sides of the center sheet 11 in the width direction X. For example, the center sheet 11 and the pair of side sheets are made of plain-colored nonwoven fabric without any design pattern.

[0051] like Figure 2 As shown, the inner portions of the pair of side panels 12 in the width direction X are folded back towards the non-skin side Z2. A pair of elastic members 13, which are elongated in the longitudinal direction Y, are disposed between the folded portions of the pair of side panels 12. The pair of side panels 12 and the pair of elastic members 13 constitute a leak-proof pleat 80. The leak-proof pleat 80 is a stand-up leak-proof pleat, positioned closer to the skin side Z1 than the absorbent core 30.

[0052] Leak-proof pleats 80 are disposed on the outer side of the absorbent core 30 in the width direction X to suppress leakage of urine excreted into the absorbent core 30 in the width direction X. In one embodiment, the leak-proof pleats 80 include: a pair of elastic members 13 extending in the longitudinal direction Y; an upright portion 81 that is erected due to the contraction of the pair of elastic members 13; a transverse fixing portion 82 that serves as an uprighting fulcrum in the width direction X of the upright portion 81; and a longitudinal fixing portion 83 that serves as an uprighting fulcrum in the longitudinal direction Y of the upright portion 81.

[0053] A pair of elastic members 13 are disposed on the inner portion of the side plate 12 in the width direction X and extend in the longitudinal direction Y. The pair of elastic members 13 are made of a stretchable material such as rubber or spandex elastic fiber that is shrinkable in the longitudinal direction. The pair of elastic members 13 are arranged apart from each other with respect to the centerline CW in the width direction X of the main body 2, and are fixed to the side plate 12 in a state of elongation in the longitudinal direction Y. The ventral ends of the pair of elastic members 13 are disposed in the ventral region 51, which will be discussed later, and the dorsal ends of the pair of elastic members 13 are disposed in the hip region 53R, which will be discussed later.

[0054] The horizontal fixing part 82 is formed on the side piece 12 at a position on the outer side in the width direction X of the upright part 81, covering approximately the entire area in the longitudinal direction Y of the main body part 2. That is, the horizontal fixing part 82 is disposed on the outer side in the width direction X of the absorbent core 30. The horizontal fixing part 82 is part of the side piece 12 and is fixed to the center piece 11. The horizontal fixing part 82 serves as an upright support point in the width direction X of the upright part 81.

[0055] The longitudinal fixing part 83 is formed on the ventral and dorsal sides of the main body part 2 at positions relative to the transverse fixing part 82 in the width direction X. The longitudinal fixing part 83 is part of the side piece 12 and is fixed to the center piece 11. The longitudinal fixing part 83 serves as the erection fulcrum in the longitudinal direction Y of the erecting part 81.

[0056] An upright portion 81 is formed between the longitudinal fixing portions 83 formed on the ventral and dorsal sides of the main body portion 2. That is, the upright portion 81 is positioned inside the transverse fixing portion 82 in the width direction X and inside the longitudinal fixing portion 83 in the longitudinal direction Y. The upright portion 81 is a part of the side piece 12 that is not fixed relative to the center piece 11. An elastic member 13 that extends in the longitudinal direction Y is connected to the upright portion 81. Because the elastic member 13 contracts in the longitudinal direction Y, causing the main body portion 2 to deform in a closing direction, the upright portion 81 is erected starting from the transverse fixing portion 82. Thus, the upright portion 81 is erected at the position where the absorbent core 30 is sandwiched from the width direction X, thereby preventing urine leakage.

[0057] The back sheet 20 forms the outermost surface of the main body 2 during wear, positioned on the non-skin side Z2. The back sheet 20 may also include a liquid-impermeable back membrane 21 and a back nonwoven fabric 22 located further away from the back membrane 21 on the non-skin side Z2. Alternatively, the length of the back membrane 21 in the width direction X may be shorter than the length of the back nonwoven fabric 22 in the width direction X, and the back nonwoven fabric 22 may extend to both sides of the back membrane 21 in the width direction X. The back nonwoven fabric 22 forms the outermost layer of the pet diaper 1. A design pattern may also be applied to the surface of the non-skin side Z2 of the back nonwoven fabric 22.

[0058] An absorbent core 30 is disposed between the surface sheet 10 and the back sheet 20. The absorbent core 30 contains, for example, plant-derived pulp fibers with absorbent properties and a superabsorbent polymer (SAP) for absorbing pet urine. Figure 2 As shown, the upper and lower surfaces of the absorbent core 30 can also be covered by the core-covering tape 38. The absorbent core 30 is disposed approximately at the center in the width direction X of the main body 2.

[0059] The absorbent core 30 has a ventral end edge 30F and a dorsal end edge 30R. The width of the ventral end edge 30F and the dorsal end edge 30R in the width direction X is greater than the distance in the width direction X between the pair of elastic members 13. A narrowing portion 43 is formed between the ventral end edge 30F and the dorsal end edge 30R, which narrows the width of the absorbent core 30. The width of the narrowing portion 43 in the width direction X is smaller than the distance in the width direction X between the pair of elastic members 13.

[0060] The narrowing portion 43 is positioned on the ventral side of the centerline CL1 in the longitudinal direction Y of the main body portion 2 and on the dorsal side of the centerline 30C in the longitudinal direction Y of the absorbent core 30. Furthermore, the centerline CL1 is an imaginary line extending along the width direction X, located at a distance equidistant from the dorsal end edge 2R and the ventral end edge 2F of the main body portion 2 (discussed later). In other words, the centerline CL1 is the portion that forms a crease when the pet diaper 1 is folded in the longitudinal direction Y.

[0061] The dorsal edge 30R of the absorbent core 30 is positioned dorsally closer to the centerline CL1 in the longitudinal direction Y of the main body 2. The ventral edge 30F of the absorbent core 30 is positioned ventrally closer to the centerline CL1. When the pet diaper 1 is worn on the pet, the pet's urination opening comes into contact with the area near the centerline CL1 of the main body 2.

[0062] The main body 2 has a ventral end edge 2F located on the ventral side in the longitudinal direction Y and a dorsal end edge 2R located on the dorsal side in the longitudinal direction Y. When worn, the ventral end edge 2F is positioned ventrally along the pet's waist, and the dorsal end edge 2R is positioned dorsally along the pet's waist. The distance in the longitudinal direction Y between the ventral end edge 2F and the dorsal end edge 2R is called the total length (maximum length) L1 of the main body 2. The maximum width W1 in the width direction X of the main body 2 can also be greater than half of the total length L1 in the longitudinal direction of the main body 2.

[0063] Additionally, the main body 2 includes: a ventral region 51 located on the ventral end edge 2F side; a dorsal region 52 located on the dorsal end edge 2R side; and an intermediate region 53 located between the ventral region 51 and the dorsal region 52 in the longitudinal direction Y. The width of the intermediate region 53 in the width direction X is approximately constant in the longitudinal direction Y. The widths of the ventral region 51 and the dorsal region 52 in the width direction X may also be larger than the width of the intermediate region 53 in the width direction X.

[0064] The middle region 53 includes a crotch region 53F located between the center line CL1 of the main body 2 and the ventral region 51, and a buttock region 53R located between the center line CL1 of the main body 2 and the dorsal region 52. The crotch region 53F is the area that covers the pet's crotch when the pet diaper 1 is put on the pet. The buttock region 53R is the area that abuts against the pet's buttocks when the pet diaper 1 is put on the pet.

[0065] A pair of wing portions 15 are formed on the ventral region 51 of the main body 2, extending outward from the main body 2 in the width direction X. The pair of wing portions 15 divides a pair of leg openings 15s for the hind legs of the pet to pass through. The width in the width direction X between the side edges of the pair of wing portions 15 is equivalent to the maximum width W1 of the main body 2.

[0066] A pair of fastening tabs 90 are provided on each of the pair of wing portions 15. Each pair of fastening tabs 90 has a rectangular shape that is longer in the width direction X when viewed from the skin side Z1, and is arranged close to the ventral end edge 2F in the longitudinal direction Y of the main body portion 2. The pair of fastening tabs 90 extend outward from the side end edge 2S of the main body portion 2 in the width direction X. Each pair of fastening tabs 90 has a base plate 91 that engages with the wing portion 15 and an engagement portion 92 provided on the base plate 91. The engagement portion 92 is disposed on the skin side Z1 surface of the fastening tab 90. The engagement portion 92 is, for example, a hook and loop fastener, configured to engage with a target portion 45 formed on the non-skin side Z2 of the main body portion 2.

[0067] The target portion 45 is located on the non-skin surface Z2 of the dorsal region 52 of the main body portion 2. For example... Figure 1 As shown, the target portion 45 has a strip-like shape extending in the width direction X. The target portion 45 is positioned on the back side edge 2R side of the pair of fastening tabs 90 and engages with the pair of fastening tabs 90. Alternatively, the main body portion 2 may not have the target portion 45, and the joint portion 92 of the pair of fastening tabs 90 may be directly joined to the back nonwoven fabric 22 of the back sheet 20.

[0068] The main body 2 has a first incision 61 and a second incision 71. The first incision 61 forms a first opening 60 through which the pet's tail passes. The second incision 71 forms a second opening 70 through which the pet's feces pass. Figure 1 As shown, the first incision portion 61 and the second incision portion 71 are positioned near the ventral side of the midline CL2 between the centerline CL1 in the longitudinal direction Y of the main body portion 2 and the ventral edge 45F of the target portion 45. That is, the first incision portion 61 and the second incision portion 71 are formed in the buttock region 53R of the main body portion 2.

[0069] Figure 3 This is a magnified view of the periphery of the first incision 61 and the second incision 71. (See diagram below.) Figure 3 As shown, the first cut portion 61 is formed on the back side of the main body 2, closer to the absorbent core 30. The second cut portion 71 is formed on the back side of the main body 2, closer to the first cut portion 61. That is, the first cut portion 61 is formed between the absorbent core 30 and the second cut portion 71 in the longitudinal direction Y. A non-cut portion 65 without a slit is provided between the first cut portion 61 and the second cut portion 71. That is, the first cut portion 61 and the second cut portion 71 are separated by the non-cut portion 65.

[0070] like Figure 3 As shown, the first incision 61 includes a generally U-shaped slit 62 that protrudes toward the absorbent core 30 when viewed from the skin side Z1. The slit 62 is disposed on a centerline CW in the width direction X and penetrates the surface sheet 10 and the back sheet 20 of the main body 2 in the thickness direction. Furthermore, the centerline CW is an imaginary line that is located at a distance equidistant from a pair of side edges 2S of the main body 2 in the width direction X and extends along the longitudinal direction Y.

[0071] The main body 2 has a wing-shaped tongue 63. The tongue 63 is formed by creating a roughly U-shaped slit in the main body 2 using a slit 62, and is partially composed of a surface plate 10 and a back plate 20. The tongue 63 has: a base end portion 63R, which is connected to the hip region 53R of the main body 2; and a tip portion 63F, which is disposed on the opposite side of the base end portion 63R and disconnected from the hip region 53R. The tip portion 63F faces the ventral side when the tongue 63 is not folded back.

[0072] The tongue 63 folds back towards the non-skin side Z2, starting from the base end 63R, thereby opening the first opening 60. The first opening 60 is a semi-circular or tongue-shaped opening that functions as a tail hole through which the pet's tail passes. The first opening 60 is located dorsally closer to the dorsal edge 30R of the absorbent core 30, therefore, areas where the absorbent core 30 is not disposed are formed on the outer and dorsal sides in the width direction X of the first opening 60.

[0073] Figure 4 This indicates the state where the tail is passed through the first opening 60 while wearing a pet diaper. The tip 63F of the tongue 63 faces the ventral side, therefore, as... Figure 4As shown, if the tail passes through the first opening 60 and the tongue 63 folds back towards the non-skin side Z2 starting from the base end 63R, the tongue 63 abuts against the dorsal side of the tail. At this time, the pet diaper 1 is positioned by the dorsal edge 60R of the first opening 60 abutting against the pet's tail.

[0074] In one implementation, such as Figure 3 As shown, the maximum width W2 of the first opening 60 in the width direction X is greater than the maximum length L2 of the first opening 60 in the longitudinal direction Y. That is, the first opening 60 has a longer transverse shape in the width direction X. Therefore, as Figure 4 As shown, when the tail passes through the first opening 60, the pet's anus will not be exposed from the first opening 60. Therefore, when the pet defecates while wearing the pet diaper 1, the feces will not pass through the first opening 60, but will be excreted into the pet diaper 1.

[0075] The second incision 71 includes a pair of slits 72. Figure 3 In the illustrated embodiment, a pair of slits 72 are separated from each other and extend obliquely relative to the centerline CW. More specifically, the pair of slits 72 extend in a straight line, moving away from each other as they move away from the absorbent core 30. The ventral ends of the pair of slits 72 are arranged adjacent to a pair of ends of a generally U-shaped slit 62. A non-cutout portion 65 is formed between the ventral ends of the pair of slits 72 and the pair of ends of the slit 62. The length of the pair of slits 72 may also be longer than the length of the pair of non-cutout portions 65.

[0076] If the fracture does not occur at the 65-degree incision site, then as follows Figure 5 As shown, the slit 62 of the first incision 61 connects with a pair of slits 72 of the second incision 71, forming a roughly U-shaped slit longer than the slit 62. The non-incision portion 65 easily breaks by grasping the tongue 63 with fingers from the non-skin side Z2 of the pet diaper 1 and pulling it towards the back. Simultaneously, the tongue 63 partially connects to the pair of slits 72 of the main body 2. With the first incision 61 and the second incision 71 connected, the second opening 70 opens by folding the tongue 63 back towards the non-skin side Z2. That is, the second incision 71, together with the first incision 61, forms the second opening 70 when the non-incision portion 65 breaks.

[0077] like Figure 5As shown, the second opening 70 is an opening that includes the first opening 60. That is, if the non-cut portion 65 is cut off to connect the first cut portion 61 and the second cut portion 71, the first opening 60 expands dorsally to form the second opening 70. The second opening 70 is a semi-circular or tongue-shaped opening that functions as an enlarged tail opening. The area of ​​the second opening 70 is larger than the area of ​​the first opening 60, allowing pet feces to pass through. In one embodiment, the area of ​​the second opening 70 may be more than twice the area of ​​the first opening 60. Figure 5 In the embodiment shown, the width of the second opening 70 in the width direction X increases as it faces the back side.

[0078] To reliably allow pet feces to pass through, the second opening 70 may also have a longer longitudinal shape in the longitudinal direction Y. For example, the maximum length L3 of the second opening 70 in the longitudinal direction Y is greater than the maximum width W3 of the second opening 70 in the width direction X. The maximum length L3 of the second opening 70 may also be more than twice the maximum length L2 of the first opening 60 in the longitudinal direction Y.

[0079] Figure 6 This diagram illustrates the state where the pet's tail is passed through the second opening 70 and the diaper 1 is fitted onto the pet. (See diagram below.) Figure 6 As shown, the second opening 70 has a longitudinal shape. Therefore, if the tail is passed through the second opening 70 and the tongue 63 is folded back towards the non-skin side Z2, the pet's anus 98 will be exposed from the second opening 70. Thus, when the pet defecates while wearing the pet diaper 1, the feces are discharged through the second opening 70 to the outside of the pet diaper 1. When the pet diaper 1 is put on the pet with the tail passed through the second opening 70, the dorsal edge 70R of the second opening 70 abuts against the pet's tail. Therefore, the position where the pet's tail abuts against the pet diaper 1 is shifted dorsally compared to the situation when the pet diaper 1 is put on the pet with the tail passed through the first opening 60.

[0080] As described above, the user of the pet diaper 1 can choose whether the pet defecates inside or outside the pet diaper 1. Specifically, if the user wants the pet to defecate inside the pet diaper 1, the pet's tail is passed through the first opening 60 without cutting off the non-cut portion 65. The first opening 60 is small enough to prevent feces from passing through, therefore, in this case, the pet's feces are excreted inside the pet diaper 1. On the other hand, if the user wants the pet's feces to defecate outside the pet diaper 1, the non-cut portion 65 is cut off, and the pet's tail is passed through the second opening 70. The second opening 70 is large enough to allow feces to pass through, therefore, in this case, the pet's feces are excreted outside the pet diaper 1.

[0081] like Figure 1 As shown, the pet diaper 1 may also include a pair of elastic members 40 that are stretchable in the longitudinal direction. The pair of elastic members 40 are positioned on the outer side of the elastic member 13 in the width direction X. Figure 1 In the illustrated embodiment, the ventral ends of a pair of elastic members 40 are disposed in the ventral region 51, and the dorsal ends of a pair of elastic members 40 are disposed in the dorsal region 52. The pair of elastic members 40 are made of a stretchable material, such as rubber or spandex fiber, which can contract in the longitudinal direction, and are disposed along the side edge 2S of the main body 2 between the surface sheet 10 and the back sheet 20. Furthermore, the pair of elastic members 40 may also extend in the longitudinal direction Y in a manner sewn to the surface sheet 10 and the back sheet 20 of the main body 2. When the pet diaper 1 is worn, the pair of elastic members 40 contract in the longitudinal direction Y, thereby conforming the side edge 2S of the main body 2 to the leg circumference of the wearer.

[0082] Reference Figure 4 or Figure 6 The method of wearing the pet diaper 1 is explained below. Before putting the pet diaper 1 on the pet, firstly, a first opening 60 or a second opening 70 is formed depending on whether the pet will defecate inside or outside the pet diaper 1. Next, the pet's tail is passed through the first opening 60 or the second opening 70 and exposed to the non-skin side Z2 of the pet diaper 1. At this time, the tongue 63 is folded back towards the non-skin side Z2 and positioned on the back side of the tail. Next, the ventral edge 2F of the main body 2 is brought into contact with the pet's abdomen. Next, the center line CL1 in the longitudinal direction Y of the main body 2 is brought into contact with the pet's urination opening, and the dorsal edge 2R of the main body 2 is brought into contact with the pet's back. Next, a pair of fastening tabs 90 are pulled towards the pet's spine in the waist direction to fix the pair of fastening tabs 90 to the outer surface of the target portion 45 of the main body 2. Thus, as Figure 4 or Figure 6 As shown, a pet diaper 1 is worn to cover the pet's abdomen, back, and crotch.

[0083] Without breaking the non-cut portion 65, the pet's tail passes through the first opening 60, such as Figure 4 As shown, the pet's anus is not exposed from the pet diaper 1, and the pet's feces are excreted into the pet diaper 1. On the other hand, if the non-cut portion 65 is severed and the pet's tail passes through the second opening 70, as... Figure 6 As shown, the pet's anus 98 is exposed from the pet diaper 1, and the pet's feces are excreted to the outside of the pet diaper 1.

[0084] like Figure 7As shown, the aforementioned pet diaper 1 is housed in a folded state within the packaging body 100. For example, the pet diaper 1 is folded back inward in the width direction X after the side panel 12 is folded three or four times in the length direction Y, and then housed within the packaging body 100. Figure 7 In the embodiment shown, multiple folded pet diapers 1 are stored in the packaging body 100 in a stacked state in the width and vertical directions of the packaging body 100.

[0085] An example of a folding method for the pet diaper 1 will be described. When storing the pet diaper 1 in the packaging body 100, firstly, the side panel 12 is folded inward in the width direction X. Next, the ventral region 51 of the main body 2 is folded towards the skin side Z1 to overlap with the crotch region 53F, and then the crotch region 53F is folded towards the skin side Z1 to overlap with the buttock region 53R. Furthermore, the buttock region 53R is folded towards the skin side Z1 to overlap with the dorsal region 52. By folding the pet diaper 1 four times in this way, the ventral region 51 and the crotch region 53F are positioned on the inside, and the dorsal region 52 and the buttock region 53R of the main body 2 are positioned on the outside.

[0086] Figure 8 This is a top view showing an example of a pet diaper 1 folded in the order described above. The first incision 61 and the second incision 71 are formed in the hip area 53R, therefore, as... Figure 8 As shown, by folding the pet diaper 1 into a body 2 with the buttock region 53R positioned on the outside, the first slit 61 and the second slit 71 are positioned on the outer surface of the folded pet diaper 1. Furthermore, in Figure 8 In the embodiment shown, the first cut portion 61 and the second cut portion 71 are generally disposed on the outer surface of the pet diaper 1, but only a portion of the first cut portion 61 and the second cut portion 71 may be disposed on the outer surface of the folded pet diaper 1.

[0087] Thus, since at least a portion of the first slit 61 and the second slit 71 are disposed on the outer surface of the folded pet diaper 1, the user can visually identify the first slit 61 and the second slit 71 when the folded pet diaper 1 is removed from the packaging 100. Therefore, the user can identify whether the pet can choose to defecate inside or outside the pet diaper 1. Furthermore, the folding method is not limited to the example described above, as long as at least a portion of the first slit 61 and the second slit 71 are disposed on the outer surface of the folded pet diaper 1.

[0088] Furthermore, in the above embodiment, the second incision 71 is formed on the dorsal side of the main body 2, closer to the first incision 61. However, the second incision 71 may also be formed on the ventral side, closer to the first incision 61. Hereinafter, refer to... Figure 9 and Figure 10 A modified example of pet diaper 1 will be explained.

[0089] like Figure 9 As shown, in the modified pet diaper, the first slit 61 is formed on the back side of the main body 2, closer to the absorbent core 30, and the second slit 71 is formed in the longitudinal direction Y between the first slit 61 and the absorbent core 30. A non-slit portion 65 without a slit is provided between the first slit 61 and the second slit 71, and the first slit 61 and the second slit 71 are separated by the non-slit portion 65.

[0090] like Figure 9 As shown, the first incision portion 61 includes a generally U-shaped slit 162 that protrudes toward the dorsal side when viewed from the skin side Z1. The main body portion 2 has a tongue 163 formed by utilizing the slit 162 to create a generally U-shaped gap in the main body portion 2. The tongue 163 has: a base portion 163F, which is connected to the buttock region 53R of the main body portion 2; and a tip portion 163R, which is disposed on the opposite side of the base portion 163F and disconnected from the buttock region 53R. The tip portion 163R faces the dorsal side when the tongue 163 is not folded back.

[0091] The tongue 163 folds back towards the non-skin side Z2, starting from its base 163F, thus opening the first opening 60. The tip 163R of the tongue 163 faces the dorsal side; therefore, when the tail passes through the first opening 60 and the tongue 163 folds back towards the non-skin side Z2, the tongue 63 abuts against the ventral side of the tail. At this time, the pet diaper 1 is positioned by the dorsal edge 60R of the first opening 60 abutting against the pet's tail.

[0092] In one implementation, such as Figure 9 As shown, the maximum width W4 in the width direction X of the first opening 60 is greater than the maximum length L4 in the longitudinal direction Y of the first opening 60. That is, the first opening 60 has a longer transverse shape in the width direction X. Therefore, when the tail passes through the first opening 60, the pet's anus will not be exposed from the first opening 60. As a result, when the pet defecates while wearing the modified pet diaper 1, the feces will not pass through the first opening 60, but will be excreted into the pet diaper 1.

[0093] The second cut 71 includes a pair of slits 172. The pair of slits 172 are separated from each other and extend in a straight line, moving away from each other as they approach the absorbent core 30. The dorsal ends of the pair of slits 172 are arranged adjacent to a pair of ends of a generally U-shaped slit 162. A non-cut portion 65 is formed between the dorsal ends of the pair of slits 172 and the pair of ends of the slit 162.

[0094] If the fracture does not occur at the 65-degree incision site, then as follows Figure 10 As shown, the slit 162 of the first incision 61 is connected to a pair of slits 172 of the second incision 71. The non-incision portion 65 easily breaks off by grasping the tongue 163 with fingers from the non-skin side Z2 and pulling it towards the ventral side. Simultaneously, the tongue 163 partially connects to the pair of slits 172 of the main body 2. With the first incision 61 and the second incision 71 connected, the second opening 70 opens by folding the tongue 163 back towards the non-skin side Z2.

[0095] like Figure 10 As shown, the second opening 70 is an opening that includes the first opening 60. That is, if the non-cut portion 65 is cut off to connect the first cut portion 61 and the second cut portion 71, the first opening 60 expands ventrally to form the second opening 70. The second opening 70 is a semi-circular or tongue-shaped opening that functions as an enlarged tail opening. The second opening 70 is large enough for pet feces to pass through. In one embodiment, the area of ​​the second opening 70 may be more than twice the area of ​​the first opening 60. Figure 10 In the embodiment shown, the width of the second opening 70 in the width direction X increases as it moves toward the ventral side.

[0096] To allow pet feces to pass through, the second opening 70 may also have a longer longitudinal shape in the longitudinal direction Y. For example, the maximum length L5 of the second opening 70 in the longitudinal direction Y may be greater than the maximum width W5 of the second opening 70 in the width direction X. In particular, the maximum length L5 of the second opening 70 may be more than twice the maximum length L4 of the first opening 60 in the longitudinal direction Y.

[0097] like Figure 10As shown, the second opening 70 has a longitudinal shape. Therefore, if the tail is passed through the second opening 70 and the tongue 163 is folded back towards the non-skin side Z2, the pet's anus will be exposed from the second opening 70. Thus, when the pet defecates while wearing the pet diaper 1, the feces are expelled through the second opening 70 to the outside of the pet diaper 1. When the pet diaper 1 is put on the pet with the tail passed through the second opening 70, the dorsal edge 70R of the second opening 70 abuts against the pet's tail.

[0098] As described above, the user of pet diaper 1 can choose whether the pet defecates inside or outside the pet diaper 1. Additionally, in Figure 10 In the illustrated embodiment, when the second opening 70 is formed, the tail hole of the pet diaper 1 expands ventrally. Therefore, the dorsal edge 70R of the second opening 70 is positioned at the same location as the dorsal edge 60R of the first opening 60. Consequently, the position where the pet's tail contacts the pet diaper 1 does not change when the tail passes through the first opening 60 and when the tail passes through the second opening 70. Therefore, the pet diaper 1 can reliably fit the pet, and deviation of the pet diaper 1 is unlikely. Thus, urine leakage can be prevented.

[0099] The above description illustrates various embodiments of pet diapers, but the present invention is not limited to these embodiments and various modifications can be made without changing the spirit of the invention. It should be noted that the above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0100] For example, the shape of the first opening 60 is not limited to a semi-circular shape or a tongue shape. For example, as... Figure 11 (a) and Figure 11 As shown in (b), the first opening 60 can also have a trapezoidal shape. Figure 11 In the pet diaper shown in (a), the first slit 61 of the first opening 60 for forming a trapezoidal shape is positioned more ventrally than the second slit 71. The pair of slits 72 of the second slit 71 extend in a straight line, moving closer to each other as they move away from the absorbent core 30. Figure 11 In the pet diaper shown in (b), the first cut 61 of the first opening 60, which forms a trapezoidal shape, is positioned on the back side compared to the second cut 71. The pair of slits 72 of the second cut 71 extend in a straight line, moving closer to each other as they approach the absorbent core 30. Furthermore, the shape of the first opening 60 can also be semi-circular, rectangular, polygonal, or elliptical.

[0101] In addition, such as Figure 12 (a) and Figure 12As shown in (b), the first cutout 61 may also include an annular slit 262 extending around the entire circumference of the end edge of the first opening 60. By forming the annular slit 262, a portion of the main body 2 is cut off, forming the first opening 60 without a tongue. Furthermore, the annular slit 262 refers to a gap that cuts off a portion of the main body 2 around its circumference; its top-view shape is not limited to a circular ring, but includes ring shapes such as rectangular rings and polygonal rings. Figure 12 In the pet diaper shown in (a), the first cut 61, including the annular slit 262, is positioned more ventrally than the second cut 71. Figure 12 In the pet diaper shown in (b), the first cut 61, including the annular slit 262, is positioned on the back side compared to the second cut 71. Figure 12 (a) and Figure 12 In the embodiment shown in (b), a first opening 60 without a tongue is formed. This allows the user to easily identify the presence of the first opening 60.

[0102] exist Figure 3 In the illustrated embodiment, the second incision 71 includes a pair of straight slits 72, but the shape of the slits in the second incision 71 is not limited to being straight. For example, the second incision 71 may also include generally V-shaped slits 172. Figure 13 In the pet diaper shown in (a), the main body 2 has: a first cutout 61 including an annular slit 262; and a second cutout 71 positioned on the back side of the first cutout 61, including a generally V-shaped slit 172 protruding towards the back side. Figure 13 In the pet diaper 1 shown in (b), the main body 2 has: a first slit 61, which includes an annular slit 262; and a second slit 71, which is located on the ventral side of the first slit 61 and includes a generally V-shaped slit 172 protruding ventrally. Furthermore, the shape of the slit in the second slit 71 can also be generally U-shaped or annular.

[0103] and Figure 1 Similarly, in the embodiments shown, Figures 11-13 In the pet diaper shown, when the pet's tail passes through the first opening 60 without breaking the non-cut portion 65, the pet's feces are excreted into the inside of the pet diaper 1. When the non-cut portion 65 is broken and the pet's tail passes through the second opening 70, the pet's feces are excreted into the outside of the pet diaper 1. Therefore, the user of the pet diaper 1 can choose whether the pet's feces are excreted into the inside or outside of the pet diaper 1.

[0104] The various implementation methods described above can be combined without contradiction.
