[0006] Problems to be Solved by the Invention

[0007] Regarding the above absorbent article for pets, there is a need to wear the absorbent article for pets in such a way that the urethral orifice of the pet is disposed between a pair of leak-proof pleats. For example, when wearing the absorbent article for pets on a male pet, it is desirable to dispose one of the pair of leak-proof pleats in front of (the head side) the pet relative to the urethral orifice, and dispose the other of the pair of leak-proof pleats behind (the hip side) the pet relative to the urethral orifice, and more preferably, dispose it between the root of the genital organ of the pet and the testicles. When the urethral orifice of the pet is not disposed between the pair of leak-proof pleats, the urine of the pet cannot be absorbed by the absorber, and urine leakage occurs.

[0008] However, users sometimes do not recognize the correct wearing method of the absorbent article for pets. In the case where the correct wearing method is not recognized, when wearing the absorbent article for pets on the pet, it is necessary to peek inside from the side of the pet to check the position of the urethral orifice while wearing the absorbent article for pets on the pet, and it is not easy to wear the absorbent article for pets in an appropriate position.

[0009] Therefore, an object of the present disclosure is to provide an absorbent article for pets that can be easily worn in an appropriate position.

[0010] Means for Solving the Problems

[0011] In one mode, a pet absorbent article is provided that is wound around the waist circumference of a pet. The pet absorbent article is wound around the waist circumference of the pet. The pet absorbent article has a main body portion that has a horizontally long shape including a long side direction and a short side direction. The main body portion includes a surface sheet disposed on the skin side, a back sheet disposed on the non-skin side, an absorbent body disposed between the surface sheet and the back sheet, and a pair of leak-proof pleats disposed outside the absorbent body in the short side direction. At least a part of one or both of the pair of leak-proof pleats is colored in a color different from that of the surface sheet.

[0012] In the above mode, since at least a part of the leak-proof pleats is colored in a color different from that of the surface sheet, the user can easily recognize the position of the leak-proof pleats. Thus, it is easy to wear the pet absorbent article while confirming the positional relationship between the urethral orifice of the pet and the leak-proof pleats. As a result, the urethral orifice of the pet can be disposed between the pair of leak-proof pleats. Therefore, it is easy to wear the pet absorbent article at an appropriate position.

[0028] [Summary of Embodiments of the Present Disclosure]

[0029] The summary of the embodiments of the present disclosure will be described with reference to the items listed below. In addition, the present disclosure includes any combination of the following items.

[0030] (Item 1)

[0031] A pet absorbent article that is wound and worn around the waist of a pet. The pet absorbent article includes a main body portion having a horizontally long shape including a long - side direction and a short - side direction. The main body portion includes a surface sheet disposed on the skin - side, a back sheet disposed on the non - skin - side, an absorbent body disposed between the surface sheet and the back sheet, and a pair of leak - proof pleats disposed outside the absorbent body in the short - side direction. At least a part of at least one of the pair of leak - proof pleats is colored in a color different from that of the surface sheet.

[0032] In the above - mentioned manner, since at least a part of the leak - proof pleats is colored in a color different from that of the surface sheet, the user can easily recognize the position of the leak - proof pleats. As a result, it is easy to wear the pet absorbent article while confirming the positional relationship between the urethral orifice of the pet and the leak - proof pleats. Therefore, the urethral orifice of the pet can be disposed between the pair of leak - proof pleats. Thus, it is easy to wear the pet absorbent article at an appropriate position.

[0033] (Item 2)

[0034] In the absorbent article for pets described in Item 1, it is also possible that the main body portion has a front edge disposed on one side in the short side direction and a rear edge disposed on the other side in the short side direction, and the pair of leak-proof pleats includes a front leak-proof pleat disposed along the front edge and a rear leak-proof pleat disposed along the rear edge, and at least a part of the rear leak-proof pleat is colored in a color different from that of the surface sheet. In this mode, since at least a part of the rear leak-proof pleat is colored in a color different from that of the surface sheet, when the absorbent article for pets is worn, the user can easily recognize the position of the rear leak-proof pleat. Therefore, it is easy to dispose the rear leak-proof pleat at an appropriate position.

[0035] (Item 3)

[0036] In the absorbent article for pets described in Item 2, it is also possible that the front leak-proof pleat and the rear leak-proof pleat each include: a side sheet that is partially fixed to the surface sheet or the back sheet; and a first elastic member that is disposed along the inner edge of the side sheet in the short side direction and is joined to the side sheet in a state of being elongated in the long side direction, and at least a part of the area of the side sheet of the rear leak-proof pleat is colored in a color different from that of the surface sheet. By coloring at least a part of the area of the side sheet in a color different from that of the surface sheet, when the absorbent article for pets is worn, the user can easily recognize the position of the rear leak-proof pleat.

[0037] (Item 4)

[0038] In the absorbent article for pets described in Item 3, it is also possible that the length of the colored area in the long side direction is 1 / 4 or more of the total length of the main body portion in the long side direction. By setting the length of the colored area in the long side direction to 1 / 4 or more of the total length of the main body portion in the long side direction, the length of the colored area is greater than the waist width of the pet. Therefore, when the absorbent article for pets is worn, the colored area can be visually recognized from above the pet. Therefore, the user can recognize the position of the rear leak-proof pleat.

[0039] (Item 5)

[0040] In the absorbent article for pets described in Item 3 or 4, it is also possible that, in the long side direction, the colored area is formed so as to straddle the absorbent body. According to this mode, the user can recognize the position of the rear leak-proof pleat.

[0041] (Item 6)

[0042] In the absorbent article for pets according to any one of Items 3 to 5, it is also possible that the inner part of the side piece in the short side direction is folded back, and the first elastic member is disposed between the folded-back side pieces. By folding back the inner part of the side piece, the side pieces are partially overlapped in a double layer, and the color of the inner edge of the side piece becomes darker. Therefore, the user can more reliably recognize the position of the inner edge of the rear leak-preventing pleat.

[0043] (Item 7)

[0044] In the absorbent article for pets according to any one of Items 3 to 6, it is also possible that the back sheet includes a liquid-impermeable back film and a back non-woven fabric disposed on the non-skin side compared to the back film. In the short side direction, the width of the back film is smaller than the width of the back non-woven fabric, and the colored area extends outward in the short side direction compared to the back film so as to be visually recognizable from the non-skin side through the back non-woven fabric. In this mode, when wearing the absorbent article for pets, if the rear end edge of the main body part is turned up and drawn into the inside, the colored area of the side piece is blocked by the back film and cannot be visually recognized. Therefore, the user can recognize the situation where the rear end edge of the main body part is drawn into the inside. Therefore, according to this mode, urine leakage caused by the drawing-in of the rear end edge can be suppressed.

[0045] (Item 8)

[0046] In the absorbent article for pets according to any one of Items 2 to 7, it is also possible that the front leak-preventing pleat and the rear leak-preventing pleat each include: a side piece that is partially fixed to the front sheet or the back sheet; and a first elastic member that is disposed along the inner edge of the side piece in the short side direction and is joined to the side piece in a state of being elongated in the long side direction. The first elastic member of the rear leak-preventing pleat is colored in a color different from that of the front sheet so as to be visually recognizable through the side piece. By coloring the first elastic member so as to be visually recognizable through the side piece, when wearing the absorbent article for pets, the user can recognize the position of the inner edge of the rear leak-preventing pleat.

[0047] (Item 9)

[0048] In the absorbent article for pets according to any one of Items 3 to 8, it is also possible that the effective length of the first elastic member is 1 / 4 or more of the full length of the main body part in the long side direction. By setting the effective length of the first elastic member to 1 / 4 or more of the full length of the main body part in the long side direction, the effective length of the first elastic member is greater than the waist width of the pet. Therefore, when wearing the absorbent article for pets, the colored first elastic member can be visually recognized from above the pet, so the user can recognize the position of the rear leak-preventing pleat.

[0049] (Item 10)

[0050] In the absorbent article for pets according to any one of Items 3 to 9, it is also possible that the inner edge of the side piece of the rear leak - proof pleat in the short - side direction does not join the surface sheet over the entire length in the long - side direction. By making the inner edge of the side piece of the rear leak - proof pleat not join the surface sheet over the entire length in the long - side direction, the rear leak - proof pleat is likely to fall outward in the short - side direction. By the rear leak - proof pleat falling outward, it is easy to visually recognize the colored first elastic member.

[0051] (Item 11)

[0052] In the absorbent article for pets according to any one of Items 3 to 9, it is also possible that the inner edge of the side piece of the rear leak - proof pleat is joined to the surface sheet in a state of being folded back outward in the short - side direction at both ends in the long - side direction. By joining the inner edge of the side piece of the rear leak - proof pleat to the surface sheet in a state of being folded back outward in the short - side direction at both ends in the long - side direction, the rear leak - proof pleat is likely to fall outward in the short - side direction. By the rear leak - proof pleat falling outward, it is easy to visually recognize the colored first elastic member.

[0053] (Item 12)

[0054] In the absorbent article for pets according to any one of Items 3 to 11, it is also possible that the side piece includes: a fixing portion joined to the surface sheet or the back sheet; and a standing portion disposed inside the fixing portion in the short - side direction, which can stand up with the inner edge of the fixing portion as a starting point, and the height of the standing portion when standing up is greater than the width between the inner edge and the rear edge of the fixing portion in the short - side direction. By setting the height of the standing portion to be greater than the width between the inner edge and the rear edge of the fixing portion, when the absorbent article for pets is worn with the standing portion standing up, the colored area extends outward compared to the rear edge and can be visually recognized from the outside. By visually recognizing the standing portion, the user can confirm that the absorbent article for pets is properly worn. Therefore, by visually recognizing the standing portion, the user can be confident in proper wearing and can eliminate the worry about urine leakage.

[0055] (Item 13)

[0056] In the absorbent article for pets described in Item 12, it is also possible that the backsheet includes a liquid-impermeable back film and a back nonwoven fabric disposed on the non-skin side as compared with the back film. In the short-side direction, the width of the back film is smaller than the width of the back nonwoven fabric, and the height of the erected portion is greater than the width between the inner edge of the fixing portion and the outer edge of the back film in the short-side direction. By setting the height of the erected portion to be greater than the width between the fixing portion and the outer edge of the back film in the short-side direction, the erected portion can be visually recognized from the outside when wearing the absorbent article for pets. Therefore, the absorbent article for pets can be worn at an appropriate position.

[0057] (Item 14)

[0058] In the absorbent article for pets described in any one of Items 3 to 13, it is also possible that the absorbent article for pets further includes a pair of second elastic members. The pair of second elastic members are disposed on the outer side in the short-side direction as compared with the first elastic member and extend along the front edge and the rear edge of the main body portion, respectively. The second elastic member extending along the rear edge among the pair of second elastic members is colored in a color different from that of the topsheet. In this mode, the colored second elastic member can be visually recognized when the absorbent article for pets is properly worn. On the other hand, if the rear edge of the main body portion is rolled inward, the colored second elastic member is blocked and cannot be visually recognized. Therefore, the user can be made to recognize the situation where the rear edge of the main body portion is rolled inward.

[0059] (Item 15)

[0060] In the absorbent article for pets described in Item 14, it is also possible that the backsheet includes a liquid-impermeable back film and a back nonwoven fabric disposed on the non-skin side as compared with the back film. In the short-side direction, the width of the back film is smaller than the width of the back nonwoven fabric, and the pair of second elastic members are joined to the outside of the back film in the short-side direction in such a manner that they can be visually recognized from the non-skin side through the back nonwoven fabric. In this mode, the colored second elastic member can be visually recognized through the back nonwoven fabric.

[0061] (Item 16)

[0062] In the absorbent article for pets described in any one of Items 2 to 15, it is also possible that at least a part of the rear leak-preventing pleat is housed in the packaging body in a folded state that can be visually recognized from the outside. In this mode, before unfolding the absorbent article for pets, the user can be made to recognize the front and rear of the absorbent article for pets.

[0064] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the description of the drawings, the same reference numerals are assigned to the same elements, and repeated descriptions are omitted. Sometimes, the drawings are simplified or exaggerated in part for easy understanding, and the dimensional ratios are not limited to those described in the drawings.

[0065] Hereinafter, an absorbent article for pets according to one embodiment will be described. Figure 1 It is a perspective view of an absorbent article 1 for pets according to one embodiment. Figure 2 It is a top view of the absorbent article 1 for pets viewed from the skin side Z1, Figure 3 It is a top view of the absorbent article 1 for pets viewed from the non-skin side Z2. Figure 4 It is along Figure 2 A cross-sectional view of the absorbent article 1 for pets taken along line A - A. Figure 5 It is along Figure 1 A cross-sectional view of the absorbent article 1 for pets taken along line B - B. Figure 6 It is along Figure 2 A cross-sectional view of the absorbent article 1 for pets taken along line C - C. Figure 7 It is along Figure 2 A cross-sectional view of the absorbent article 1 for pets taken along line D - D. Figures 1 - 7 The absorbent article 1 for pets shown is a disposable diaper for pets that absorbs the urine of pets.

[0066] In Figure 2 and Figure 3 The unfolded state of the absorbent article 1 for pets in a state where the absorbent article 1 for pets is stretched until there are no wrinkles is shown. The skin side Z1 refers to the side of the absorbent article 1 for pets that faces the skin of the pet in the worn state, and the non-skin side Z2 refers to the side of the absorbent article 1 for pets that faces the side opposite to the skin of the pet in the worn state. In the following description, the person who wears the absorbent article 1 for pets on the pet is referred to as the "user". Typically, the user is the owner of the pet. In the following description, unless otherwise specified, the positional relationships in the unfolded state are described.

[0067] In this specification, pets broadly include vertebrates and invertebrates, and typically include pet animals such as dogs, cats, rabbits, hamsters, etc. The absorbent article 1 for pets is particularly suitable for use on male pets whose urethral orifice is located in a position in front of the root of the hind legs. As Figure 2 and Figure 3As shown, the absorbent article 1 for pets extends in the short side direction X arranged along the front-back direction (the direction connecting the head and the hips) of the pet and in the long side direction Y arranged along the waist circumference direction of the pet. The short side direction X and the long side direction Y are perpendicular to each other. The thickness direction Z is perpendicular to the short side direction X and the long side direction Y, including the skin side Z1 facing the pet's skin surface in the worn state and the non-skin side Z2 facing the side opposite to the pet's skin surface in the worn state. The absorbent article 1 for pets is wound and worn around the pet's waist circumference.

[0068] The absorbent article 1 for pets includes a main body portion 2. The main body portion 2 has a substantially rectangular (landscape-shaped) planar shape including the short side direction X and the long side direction Y. The main body portion 2 has a front edge 3 arranged on one end side in the short side direction X and a rear edge 4 arranged on the other end side in the short side direction X. When the absorbent article 1 for pets is worn on the pet, the front edge 3 is arranged on the front leg side of the pet, and the rear edge 4 is arranged on the rear leg side of the pet. In the following description, the direction in the short side direction close to the front edge 3 is sometimes referred to as the front side, and the direction in the short side direction close to the rear edge 4 is sometimes referred to as the rear side. In addition, the main body portion 2 has a first side edge 5 arranged on one end side in the long side direction Y and a second side edge 6 arranged on the other end side in the long side direction Y.

[0069] As Figures 1 - 6 shown, the main body portion 2 includes a topsheet 10, a backsheet 20, an absorbent body 30, and a pair of leak-proof pleats 40. The topsheet 10 forms the surface of the main body portion 2 that contacts the pet and is arranged on the skin side Z1. The topsheet 10 has, for example, liquid permeability that allows the pet's urine to penetrate to the absorbent body 30 side. The topsheet 10 is located substantially at the center in the short side direction X. Typically, the topsheet 10 is made of a non-woven fabric with a white base.

[0070] The backsheet 20 forms the surface of the main body portion 2 that is located outside during wearing and is arranged on the non-skin side Z2. The backsheet 20 includes a liquid-impermeable back film 21 and a back non-woven fabric 22 arranged on the non-skin side Z2 compared to the back film 21. In the short side direction X, the width of the back film 21 is smaller than the width of the back non-woven fabric 22, and the back non-woven fabric 22 extends toward both sides in the short side direction X compared to the back film 21. The back non-woven fabric 22 forms the outermost layer of the absorbent article 1 for pets.

[0071] The absorber 30 is disposed between the top sheet 10 and the back sheet 20. The absorber 30 absorbs the urine of the pet. The absorber 30 is substantially rectangular in shape extending in the longitudinal direction Y. In one embodiment, the absorber 30 includes: an absorbent core containing pulp having water absorbency and a superabsorbent polymer (SAP); and a core wrap sheet covering the surface of the absorbent core. As the pulp of the absorbent core, for example, cellulose fibers such as chemical pulp, cellulose fiber, rayon, and acetate fiber can be used. As the superabsorbent polymer, for example, granular or fibrous polymers of starch-based, acrylic-based, and amino acid-based can be used. Typically, the core wrap sheet is made of thin paper or non-woven fabric with a white background. Additionally, the core wrap sheet may not be colored.

[0072] A pair of leak-proof pleats 40 are disposed outside the absorber 30 in the short side direction X to prevent the urine of the pet excreted onto the absorber 30 from leaking in the short side direction X. The pair of leak-proof pleats 40 are disposed so as to cover both side portions of the top sheet 10 in the short side direction X from the skin surface side Z1 and extend in the longitudinal direction Y over the entire length of the main body portion 2 in the longitudinal direction Y. The pair of leak-proof pleats 40 include a front leak-proof pleat 41 provided along the front edge 3 and a rear leak-proof pleat 51 provided along the rear edge 4. In the following description, when there is no need to particularly distinguish, the front leak-proof pleat 41 and the rear leak-proof pleat 51 may sometimes be collectively referred to as the leak-proof pleat 40.

[0073] In one embodiment, the front leak-proof pleat 41 includes a side sheet 42 locally fixed to the top sheet 10 or the back sheet 20 and a first elastic member 43 joined to the side sheet 42. The rear leak-proof pleat 51 includes a side sheet 52 locally fixed to the top sheet 10 or the back sheet 20 and a first elastic member 53 joined to the side sheet 52. The pair of side sheets 42, 52 are each made of non-woven fabric having waterproofness or hydrophobicity. For example, the side sheets 42, 52 are made of spunlace non-woven fabric, spunbond non-woven fabric, heat-bonded non-woven fabric, meltblown non-woven fabric, SMS non-woven fabric, needle-punched non-woven fabric, or hot air non-woven fabric.

[0074] The pair of side sheets 42, 52 each have a longitudinally long shape that is long in the longitudinal direction Y and extend in the longitudinal direction Y over the entire length of the main body portion 2 in the longitudinal direction Y. As Figures 4 - 6 shown, the pair of leak-proof pleats 40 extend outward compared to the back film 21. More specifically, the outer edge of the front leak-proof pleat 41 in the short side direction X coincides with one outer edge of the back non-woven fabric 22 in the short side direction X and constitutes the front edge 3 together with one outer edge of the back non-woven fabric 22. The outer edge of the rear leak-proof pleat 51 in the short side direction X coincides with the other outer edge of the back non-woven fabric 22 in the short side direction and constitutes the rear edge 4 together with the other outer edge of the back non-woven fabric 22.

[0075] As Figure 5 shown, the side pieces 42 and 52 include a fixing portion 45 joined to the front surface piece 10 or the back surface piece 20, and a standing portion 46 not joined to the front surface piece 10. The fixing portion 45 is joined to the front surface piece 10 or the back surface piece 20 with, for example, a hot melt adhesive. The standing portion 46 is disposed inside the main body portion 2 compared to the fixing portion 45 in the short side direction X, and can stand up starting from the inner edge 45a of the fixing portion 45.

[0076] As Figure 5 shown, the height H of the standing portion 46 that stands up starting from the inner edge 45a of the fixing portion 45 is greater than the width W1 between the inner edge 45a and the outer edge of the back film 21 in the short side direction X. In addition, the height H of the standing portion 46 is greater than the width W2 between the inner edge 45a of the fixing portion 45 and the rear end edge 4 in the short side direction X. In addition, the height H of the standing portion 46 is the maximum height of the standing portion 46 in the thickness direction Z with respect to the inner edge 45a as a reference.

[0077] As Figure 4 and Figure 6 shown, both ends of the inner edge 44 of the side piece 42 of the front leak - proof pleat 41 in the long side direction Y are joined to the front surface piece 10. More specifically, the side piece 42 of the front leak - proof pleat 41 is joined to the front surface piece 10 in a state of inclining inward in the short side direction X near the first side end edge 5 and the second side end edge 6. The portion of the side piece 42 of the front leak - proof pleat 41 in the long side direction Y other than both ends of the inner edge 44 is not joined to the front surface piece 10. Both ends of the inner edge 44 of the side piece 42 of the front leak - proof pleat 41 in the long side direction Y serve as standing fulcrums of the side piece 42 in the long side direction Y. As described above, by joining both ends of the inner edge 44 of the side piece 42 of the front leak - proof pleat 41 in the long side direction Y to the front surface piece 10 in a state of inclining inward in the short side direction X, in the unfolded state, the side piece 42 of the front leak - proof pleat 41 is in a state of inclining inward in the short side direction X.

[0078] On the other hand, the inner edge 54 of the side piece 52 of the rear leak - proof pleat 51 is not joined to the front surface piece 10 throughout the entire length in the long side direction Y. By making the inner edge 54 of the side piece 52 of the rear leak - proof pleat 51 not joined to the front surface piece 10 throughout the entire length in the long side direction Y, as Figure 2 、 4As shown in FIGS. 6, in the unfolded state, the side piece 52 of the rear leak-proof pleat 51 is in a state of tilting outward in the short side direction X. By the side piece 52 tilting outward, the distance between the inner edges 44 and 54 of the pair of leak-proof pleats 40 in the short side direction X becomes longer, and the area for arranging the urethral orifice of the pet becomes larger. Therefore, it is easy to wear the pet absorbent article 1 at an appropriate position, and urine leakage can be suppressed. In addition, in the unfolded state, the rear leak-proof pleat 51 is tilted outward, so that the inner edge 54 of the side piece 52 of the rear leak-proof pleat 51 approaches the rear end edge 4. Therefore, it is also easy to wear the pet absorbent article 1 for a pet with the urethral orifice near the hind legs.

[0079] In addition, as described above, in the unfolded state, the front leak-proof pleat 41 is tilted inward in the short side direction X, and the rear leak-proof pleat 51 is tilted outward in the short side direction X. The user can easily recognize the front and rear orientations of the pet absorbent article 1 based on the difference in this configuration. As a result, it is easy to understand the orientation of wearing the pet absorbent article 1, and a sense of reassurance can be brought to the user.

[0080] As Figure 5 shown, the inner portions of the side pieces 42 and 52 in the short side direction X are folded back, and the first elastic members 43 and 53 are respectively arranged between the folded-back side pieces 42 and 52. Therefore, as Figure 2 shown, the first elastic member 43 of the front leak-proof pleat 41 is arranged along the inner edge 44 of the side piece 42, and the first elastic member 53 of the rear leak-proof pleat 51 is arranged along the inner edge 54 of the side piece 52. The first elastic members 43 and 53 are respectively joined to the side pieces 42 and 52 in a state of being stretched in the long side direction Y. The first elastic members 43 and 53 are made of stretchable materials such as rubber or spandex that can contract in the length direction, for example.

[0081] The effective length of the first elastic members 43 and 53 can be more than 1 / 4 or more than 1 / 2 of the full length of the main body portion 2 in the long side direction Y. The effective length refers to the length of the actually contracted portion of the first elastic members 43 and 53 in the unfolded state. As Figure 2 shown, both ends of the first elastic members 43 and 53 are arranged outside the absorbent body 30 in the long side direction Y. That is, the first elastic members 43 and 53 are formed so as to straddle the absorbent body 30 in the long side direction. By the first elastic members 43 and 53 contracting in the long side direction Y, the standing portions 46 of the side pieces 42 and 52 stand up outside the absorbent body 30 in the short side direction X with the inner edge 45a of the fixing portion 45 as the starting point. By the standing portions 46 of the pair of leak-proof pleats 40 standing up, urine of the pet can be prevented from leaking along the surface of the surface sheet 10.

[0082] At least a part of one or both of the pair of leak - preventing pleats 40 is colored in a color different from that of the surface sheet 10. For example, it is also possible that only one of the pair of leak - preventing pleats 40 is colored and the other of the pair of leak - preventing pleats 40 is not colored. In Figure 2 the illustrated embodiment, the side piece 52 of the rear leak - preventing pleat 51 among the pair of leak - preventing pleats 40 is colored in a color different from that of the surface sheet 10. That is, in the pet absorbent article 1, only the side piece 52 of the rear leak - preventing pleat 51 among the pair of leak - preventing pleats 40 is colored, and the side piece 42 of the front leak - preventing pleat 41 is not colored. In addition, coloring means imparting a desired color to a part or the whole of the pair of leak - preventing pleats 40 using a coloring agent such as a pigment or a dye. Different colors mean colors with different degrees of difference in lightness, chroma, or hue that can be visually distinguished. More specifically, when the color difference numerically defined based on the CIE1976 color space defined by JIS Z8729 or the like is 1.5 or more or 3.0 or more, they are different colors.

[0083] The colored area of the side piece 52 is Figure 2 the area filled with slashes in Figure 2 the illustrated embodiment. That is, in the illustrated embodiment, the entire area of the side piece 52 of the rear leak - preventing pleat 51 is colored. Since the colored side piece 52 extends outward in the short - side direction X compared to the back film 21, it can be visually recognized from the non - skin - side Z2 through the back non - woven fabric 22. By making the colored side piece 52 visually recognizable through the back non - woven fabric 22, the side piece 52 can be visually recognized even when the pet absorbent article 1 is in a folded state. As a result, the front - rear orientation of the pet absorbent article 1 can be grasped before the pet absorbent article 1 is unfolded. Therefore, the pet absorbent article 1 can be smoothly worn on the pet.

[0084] However, when the pet absorbent article 1 is worn on the pet, if the rear edge 4 of the main body portion 2 is turned up and rolled inside, the rear leak - preventing pleat 51 is covered by the back non - woven fabric 22, which may prevent the rear leak - preventing pleat 51 from standing up properly. If the rear leak - preventing pleat 51 does not stand up properly, urine leakage may occur from this part. As described above, by making the colored side piece 52 visually recognizable through the back non - woven fabric 22, the user can visually recognize the standing - up state of the rear leak - preventing pleat 51 from the outside, and thus can confirm whether the pet absorbent article 1 is properly worn. Therefore, the user's concern about urine leakage can be suppressed. In addition, when the core covering sheet of the absorbent body 30 is colored, the side piece 52 may also have a color different from that of the core covering sheet. When other sheet members such as an intermediate sheet are provided between the surface sheet 10 and the absorbent body 30, the side piece 52 may also have a color different from that of the other sheet member.

[0085] If the surface sheet 10 and the side sheet 52 are the same color, it is difficult to visually distinguish between the surface sheet 10 and the side sheet 52. When wearing the pet absorbent article 1, it is difficult for the user to recognize the position of the rear leak-proof pleat 51. In contrast, by coloring the side sheet 52 of the rear leak-proof pleat 51 a different color from the surface sheet 10, the position of the rear leak-proof pleat 51 can be easily recognized. In order to easily distinguish between the surface sheet 10 and the side sheet 52, the side sheet 52 can also be colored in a conspicuous color such as red, blue, or green.

[0086] As described above, since the inner part of the side sheet 52 in the short side direction X is folded back, a single-layer region and a double-layer region are formed in the side sheet 52, with the double-layer region being disposed closer to the inner edge 54 than the single-layer region. The color of the double-layer region is darker than that of the single-layer region. Therefore, the user can grasp the position of the inner edge 54 of the rear leak-proof pleat 51 based on the color difference between the single-layer region and the double-layer region.

[0087] The pet absorbent article 1 further includes a pair of second elastic members 61, 62 and a hook-and-loop fastener 63. The pair of second elastic members 61, 62 are made of a stretchable material such as rubber or spandex that can contract in the length direction, for example. The second elastic member 61 is disposed on the front side relative to the first elastic member 43 and extends in the long side direction Y along the front edge 3 of the main body portion 2. The second elastic member 62 is disposed on the rear side relative to the first elastic member 53 and extends in the long side direction Y along the rear edge 4 of the main body portion 2. More specifically, as Figure 5 shown, the pair of second elastic members 61, 62 are respectively disposed between a pair of leak-proof pleats 40 and the back non-woven fabric 22 on the outside of the back film 21 in the short side direction X and are joined to the main body portion 2 in a state of being stretched in the long side direction Y. The pair of second elastic members 61, 62 can also be provided over the entire length of the main body portion 2.

[0088] As Figures 1 - 3 shown, the hook-and-loop fastener 63 has a rectangular shape that is long in the short side direction X and is disposed close to the first side edge 5 of the main body portion 2. The hook-and-loop fastener 63 is disposed on the non-skin side Z2 of the main body portion 2. The hook-and-loop fastener 63 is, for example, a mechanical fastener that can engage with the surface sheet 10 from the skin side Z1.

[0089] Next, with reference to Figures 8 - 11 the procedure for wearing the pet absorbent article 1 on a pet will be described. When wearing the pet absorbent article 1 on a pet, first, as Figure 8 shown, the user presses the first side edge 5 of the pet absorbent article 1 against the pet's back and holds down the vicinity of the first side edge 5 with one hand. Next, the user holds the vicinity of the second side edge 6 of the pet absorbent article 1 with the other hand and wraps the pet absorbent article 1 so as to cover the pet's abdomen.

[0090] At this time, the pet absorbent article 1 is worn in such a manner that the front leak-preventing pleat 41 is disposed in front of the urethral orifice of the pet and the rear leak-preventing pleat 51 is disposed behind the urethral orifice of the pet. For example, when the pet absorbent article 1 is worn on a male pet, it is important to dispose the end (urethral orifice) of the penis between a pair of leak-preventing pleats 40. More specifically, as shown in Figure 9 , it is preferable to dispose the inner edge 54 of the rear leak-preventing pleat 51 in the region 73 between the root of the penis 71 and the testis 72 of the pet. By disposing the rear leak-preventing pleat 51 at this position, the position of the rear leak-preventing pleat 51 is stable and unlikely to shift. The user wears the pet absorbent article 1 while peeking at the position of the pet's genitalia from the side in order to wear the pet absorbent article 1 at an appropriate position. At this time, if the surface sheet 10 of the pet absorbent article 1 and the side sheet 52 of the rear leak-preventing pleat 51 are the same color, it is difficult to recognize the position of the inner edge 54 of the rear leak-preventing pleat 51, and it is not easy to wear the pet absorbent article 1 at an appropriate position. In contrast, in the pet absorbent article 1, since the side sheet 52 of the rear leak-preventing pleat 51 is colored in a color different from that of the surface sheet 10, the position of the rear leak-preventing pleat 51 can be easily recognized. Therefore, the pet absorbent article 1 can be worn at an appropriate position while confirming the positional relationship between the pet's genitalia and the rear leak-preventing pleat 51.

[0091] Next, as shown in Figure 10 , the user lifts the second side edge 6 upward so that the pet absorbent article 1 is in close contact with the waist circumference of the pet, and then, as shown in Figure 11 , causes the surface sheet 10 to engage with the hook-and-loop fastener 63 in the vicinity of the second side edge 6. Thereby, the pet absorbent article 1 is worn on the pet at an appropriate position.

[0092] In addition, in one embodiment, as shown in Figure 12 , it may be that only a part of the side sheet 52 of the rear leak-preventing pleat 51 is colored in a color different from that of the surface sheet 10. In Figure 12In the illustrated embodiment, the colored region in the side piece 52 has a length L1 that is 1 / 4 or more, or 1 / 2 or more, of the total length L of the main body portion 2 in the longitudinal direction Y, and is formed so as to straddle the absorber 30. By setting the length in the longitudinal direction Y of the colored region to 1 / 4 or more of the total length L of the main body portion 2 in the longitudinal direction Y, the length L1 of the colored region is greater than the waist width of the pet. Therefore, when the user wears the pet absorbent article 1, the colored region of the side piece 52 can be visually recognized from the dorsal side (upper side). As a result, the position of the inner edge 54 of the side piece 52 can be easily confirmed, and as a result, it can be easily recognized whether the rear leak - proof pleat 51 is disposed at an appropriate position relative to the urethral orifice. In addition, the area of the colored region of the side piece 52 may also be 1 / 4 or more, 1 / 2 or more, or 3 / 4 or more of the entire area of the side piece 52.

[0093] As described above, in the pet absorbent article 1, since at least a part of the side piece 52 of the rear leak - proof pleat 51 is colored in a color different from that of the surface sheet 10, the user can easily recognize the position of the rear leak - proof pleat 51. Therefore, the pet absorbent article 1 can be worn while confirming the positional relationship between the urethral orifice of the pet and the rear leak - proof pleat 51 in such a manner that the urethral orifice of the pet is disposed between the pair of leak - proof pleats 40. Thus, the pet absorbent article 1 can be worn at an appropriate position.

[0094] In the case where the configurations of the pair of leak - proof pleats 40 are different as described above, specifically, in the case where the side piece 42 of the front leak - proof pleat 41 is inclined inward in the short - side direction X and the side piece 52 of the rear leak - proof pleat 51 is inclined outward in the short - side direction X in the unfolded state, it is necessary to wear the pet absorbent article 1 with the front and rear in the correct orientation. In contrast, in the pet absorbent article 1, since the rear leak - proof pleat 51 is colored and the front leak - proof pleat 41 is not colored, the orientation of the front and rear of the pet absorbent article 1 can be easily grasped.

[0095] Next, a pet absorbent article according to another embodiment will be described. Figure 13 It is a plan view of the pet absorbent article 1A according to another embodiment as viewed from the skin - side Z1. Figure 13 The illustrated pet absorbent article 1A is different from the Figure 1 illustrated pet absorbent article 1 in that the first elastic member 53 of the rear leak - proof pleat 51 is colored in a color different from that of the surface sheet 10. In the following description, the differences from the above - described pet absorbent article 1 will be mainly described, and repeated descriptions will be omitted.

[0096] In the pet absorbent article 1A, the side piece 52 of the rear leak - proof pleat 51 is not colored and has the same color system as the surface sheet 10. On the other hand, the first elastic member 53 of the rear leak - proof pleat 51 is colored in a color different from that of the surface sheet 10 so as to be visually recognizable through the side piece 52. Since the first elastic member 53 of the rear leak - proof pleat 51 extends along the inner edge 54 of the side piece 52, if the colored first elastic member 53 can be visually recognized through the side piece 52, the position of the inner edge 54 of the rear leak - proof pleat 51 can be recognized. Similarly to Figure 2 the pet absorbent article 1 shown, in the pet absorbent article 1A, since the positional relationship between the pet's genitalia and the inner edge 54 of the rear leak - proof pleat 51 can be easily recognized, the pet absorbent article 1 can be worn at an appropriate position.

[0097] As described above, since the effective length of the first elastic member 53 is more than 1 / 4 of the total length of the main body portion 2 in the long - side direction Y, the length of the colored first elastic member 53 is greater than the waist width of the pet. Therefore, when wearing the pet absorbent article 1A, the user can visually recognize the colored first elastic member 53 from the dorsal side (upper side). As a result, it can be easily recognized whether the rear leak - proof pleat 51 is arranged at an appropriate position relative to the urethral orifice.

[0098] In one embodiment, the second elastic member 62 extending along the rear end edge 4 may also be colored in a color different from that of the surface sheet 10 so as to be visually recognizable through the back non - woven fabric 22 from the skin - side Z1 or the non - skin - side Z2. When the pet absorbent article 1A is worn on a pet, if the rear end edge 4 of the main body portion 2 is turned up and rolled inside, urine leakage may sometimes occur from the rolled - in part. If the second elastic member 62 is colored in a color different from that of the side piece 52, when the rear end edge 4 of the main body portion 2 is rolled inside, the colored second elastic member 62 is blocked by the back film 21 and cannot be seen. Thus, the user can recognize the situation where the rear end edge 4 of the main body portion 2 is rolled inside. Therefore, the pet absorbent article 1A can be worn appropriately.

[0099] The pet absorbent article according to various embodiments has been described above, but the present invention is not limited to the above - described embodiments, and various modified forms can be formed within the scope of not changing the inventive concept. That is, it should be noted that the above - described embodiments are for illustrative purposes and do not limit the scope of the present invention.

[0100] For example, in the above-described embodiment, only the side piece 52 or the first elastic member 53 of the rear leak-preventing pleat 51 is colored, but it is also possible that both the side piece 42 or the first elastic member 43 of the front leak-preventing pleat 41 and the side piece 52 or the first elastic member 53 of the rear leak-preventing pleat 51 are colored in a color different from that of the surface sheet 10. Further, in one embodiment, it is also possible that the side piece 52 or the first elastic member 53 of the rear leak-preventing pleat 51 is not colored, and the side piece 42 or the first elastic member 43 of the front leak-preventing pleat 41 is colored in a color different from that of the surface sheet 10. Since the position of the front leak-preventing pleat 41 is also easily recognizable in this case, when the user wears the pet absorbent article 1 or 1A, it is easy to recognize the positional relationship between the urethral orifice of the pet and the front leak-preventing pleat 41. Therefore, the pet absorbent article 1 or 1A can be worn at an appropriate position.

[0101] In Figure 2 the embodiment shown, the inner edge 54 of the side piece 52 of the rear leak-preventing pleat 51 does not engage with the surface sheet 10 throughout the entire length in the longitudinal direction Y, but in one embodiment, the inner edge 54 of the side piece 52 of the rear leak-preventing pleat 51 in the short side direction X may also engage with the surface sheet 10 in a state of being folded back outward in the short side direction X at both end portions in the longitudinal direction Y. By engaging both end portions of the inner edge 54 of the side piece 52 of the rear leak-preventing pleat 51 with the surface sheet 10 in a state of being folded back outward, the side piece 52 of the rear leak-preventing pleat 51 is likely to fall outward in the short side direction X in the unfolded state.

[0102] Regarding the pet absorbent articles 1 and 1A, it is also possible that the side piece 52 or the first elastic member 53 of the rear leak-preventing pleat 51 is colored and is housed in the package in a folded state such that the colored side piece 52 or the first elastic member 53 can be visually recognized from the outside. By folding in such a way that the colored portion can be visually recognized from the outside, before unfolding the pet absorbent article 1 or 1A, the user can recognize the front and rear of the pet absorbent article 1 or 1A. Therefore, the pet absorbent article 1 or 1A taken out from the package can be smoothly worn on the pet in an appropriate orientation. The above-described various embodiments can be combined within a range without contradiction.
