Summary of the Invention

Problems to be Solved by the Invention

[0004] In the absorbent article described in Patent Document 1 above, in order to suppress urine leakage, strip-shaped three-dimensional gathers are provided on both the front leg side and the rear leg side of the surface in contact with the pet's body. Male pets urinate from the urethral orifice toward the front leg side. At this time, the three-dimensional gathers on the front leg side receive the excreted urine and return it to the side of the absorbent body, assisting in collecting the urine.

[0005] However, some pets urinate forcefully toward the front leg side, and depending on the posture during urination, the three-dimensional gathers may shift, resulting in urine leakage from the three-dimensional gathers on the front leg side, and improvement has been demanded.

BEST MODE FOR CARRYING OUT THE INVENTION

[0023] Hereinafter, with reference to FIGS. 1 to 10, the absorbent article for pets according to the present embodiment will be described. In all the following drawings, for the sake of clarity, the dimensions, ratios, etc. of each component are appropriately different. In the following description, the absorbent article for pets may be simply referred to as an "absorbent article".

[0024] FIG. 1 is a schematic view showing a wearing state of the absorbent article 1 for pets according to the present embodiment. The absorbent article 1 is suitably used for male pets. The absorbent article 1 absorbs and holds the liquid discharged from the pet P inside. The liquid to be absorbed refers to the liquid discharged from the body of the pet P, and typically includes urine discharged by the pet P. In addition, blood and semen are also included. Hereinafter, urine will be taken as an example of the liquid to be absorbed, and the absorbent article 1 will be described.

[0025] In the following description, an example in which the pet wearing the absorbent article 1 is a dog is shown, but the absorbent article 1 may be worn on other pets. For example, the absorbent article 1 may be worn on a cat.

[0026] The absorbent article 1 of the present embodiment has a belt-like shape and has a longitudinal direction, a width direction, and a thickness direction that are orthogonal to each other. As shown in FIG. 1, the absorbent article 1 is worn so that the longitudinal direction is along the body circumference direction of the pet P, and is wound around the waist H of the pet P in front of (the head side) the thigh portion T of the pet P.

[0027] In the present embodiment, "belt-like" is an expression indicating a state of extending long in one direction. In this sense, the "belt-like shape" is not limited to a mathematical rectangle, and the shape of the sides may not be straight.

[0028] When the absorbent article 1 is worn in such a posture, the absorbent article 1 can cover the urethral orifice of the pet P and absorb and hold the urine excreted by the pet P.

[0029] In the following description, the surface of the absorbent article 1 facing the pet P during wearing is referred to as the "front surface", and the surface facing the outside, which is opposite to the pet P during wearing, is referred to as the "back surface".

[0030] FIG. 2 is a schematic perspective view showing the absorbent article 1 of the present embodiment. FIG. 3 is an exploded cross-sectional view in the cross-sectional view taken along the line III-III of FIG. 2. FIG. 4 is a plan view of the absorbent article 1.

[0031] In the following description, an xyz orthogonal coordinate system is set, and the positional relationship of each member will be described with reference to this xyz orthogonal coordinate system. Here, a predetermined direction in the horizontal plane is defined as the x-axis direction, a direction orthogonal to the x-axis direction in the horizontal plane is defined as the y-axis direction, and a direction orthogonal to each of the x-axis direction and the y-axis direction (i.e., the vertical direction) is defined as the z-axis direction.

[0032] As shown in FIGS. 2 and 3, the absorbent article 1 of the present embodiment includes a main body portion 10, and a pair of first leakage suppression portions 20 and second leakage suppression portions 30.

[0033] In the absorbent article 1, the head side of the pet P in the wearing state shown in FIG. 1 is denoted by reference sign A, and the buttocks side of the pet P in the wearing state is denoted by reference sign B.

[0034] (Main body portion) The main body portion 10 has a strip-like appearance extending in the x-axis direction. The length of the main body portion 10 in the y-axis direction is shorter than the length in the x-axis direction. The x-axis direction corresponds to the "longitudinal direction" in the present invention. Also, the y-axis direction corresponds to the "width direction" in the present invention. Further, the z-axis direction corresponds to the "thickness direction" in the present invention.

[0035] The longitudinal direction of the main body portion 10 is represented by reference sign X, and the width direction of the main body portion 10 is represented by reference sign Y.

[0036] The main body portion 10 includes a surface sheet 11, a back surface layer 12, and an absorber 13. The surface sheet 11, the back surface layer 12, and the absorber 13 are laminated in the thickness direction (z-axis direction).

[0037] The front sheet 11 is located on the side of the front surface 10a of the main body 10 and constitutes the front surface 10a of the main body 10.

[0038] The front sheet 11 allows liquid (the urine of pet P) to permeate. The front sheet 11 is made of, for example, a non-woven fabric.

[0039] The back layer 12 is located on the side of the back surface 10b of the main body 10 and constitutes the back surface 10b of the main body 10. The back layer 12 does not allow liquid (the urine of pet P) to permeate.

[0040] The back layer 12 has a waterproof film 121 that does not allow the urine of pet P to permeate and a non-woven fabric 122 provided outside the waterproof film 121. Printing may be applied to the surface 121a on the back side of the waterproof film 121. Also, printing may be applied to the non-woven fabric 122.

[0041] In the absorbent article 1 shown in FIG. 3, the length in the width direction of the front sheet 11 and the length in the width direction of the waterproof film 121 are the same. Also, the length in the width direction of the non-woven fabric 122 is longer than the length in the width direction of the front sheet 11 and the length in the width direction of the waterproof film 121. The non-woven fabric 122 completely covers the front sheet 11 and the waterproof film 121 in the view from the back side.

[0042] The absorber 13 is disposed between the front sheet 11 and the back layer 12. The absorber 13 absorbs liquid (the urine of pet P). As shown in FIG. 2, the absorber 13 extends in the longitudinal direction X of the absorbent article 1 and is disposed at the center in the longitudinal direction X of the absorbent article. The length in the width direction Y of the absorber 13 is shorter than the length in the longitudinal direction X of the absorber 13.

[0043] The absorber 13 can adopt a configuration known as an absorber for absorbent articles for pets. For example, the absorber 13 has a core made of an absorbent material and a wrap material that wraps the core, and is a member rectangular in plan view.

[0044] Examples of absorbent materials include fluff pulp and superabsorbent polymers. Examples of fluff pulp include chemical pulp, cellulose fibers, rayon, and artificial cellulose fibers such as acetate. Examples of superabsorbent polymers include starch-based, acrylic acid-based, and amino acid-based particulate or fibrous polymers.

[0045] Examples of wrapping materials include non-woven wraps and tissue wraps.

[0046] (First leakage suppression part) The first leakage suppression part 20 is provided on the surface sheet 11 side of the main body part 10. The first leakage suppression part 20 is a belt-shaped member extending along the longitudinal direction X of the main body part 10.

[0047] The first leakage suppression part 20 is made of a hydrophobic non-woven fabric and has a first suppression part main body 200 extending in the longitudinal direction X and an elastic member 201 attached along the longitudinal direction of the first suppression part main body 200. The non-woven fabric, which is the material of the first leakage suppression part 20, may be water-repellent processed.

[0048] The first suppression part main body 200 is joined along the longitudinal direction X to the main body part 10 (the surface sheet 11 and the back layer 12) at the end A on the head side in the width direction Y of the main body part 10. The joining method may be fusion bonding or adhesion.

[0049] In the following description, the "end part" refers to a region including a certain range including the edge of the article. Also, the "end" refers to the edge of the article. The same applies to the "one end" and the "other end".

[0050] The first leakage suppression part 20 has a first joint part 20X which is a region joined to the main body part 10 and a first standing part 20Y which is a region not joined to the main body part 10.

[0051] The first joint portion 20X is the head-side A end in the width direction Y of the first leakage suppression portion 20, and is an area joined to the main body portion 10 (the front surface sheet 11 and the back surface layer 12). The first joint portion 20X is provided along the longitudinal direction X at the head-side A end of the first leakage suppression portion 20. The joining method may be fusion bonding or adhesion.

[0052] The first upright portion 20Y is the tail-side B end in the width direction Y of the first leakage suppression portion 20, and is an area not joined to the main body portion 10. The first upright portion 20Y is provided along the longitudinal direction X at the tail-side B end of the first leakage suppression portion 20.

[0053] Furthermore, as shown in FIG. 4, the first leakage suppression portion 20 may be provided with a third joint portion 20Z that joins to the front surface sheet 11. In the present embodiment, the third joint portion 20Z is provided at both ends in the longitudinal direction X at the tail-side B end in the width direction Y of the first leakage suppression portion 20.

[0054] When the first leakage suppression portion 20 joins to the front surface sheet 11 at the third joint portion 20Z, the range of the first upright portion 20Y is the tail-side B end in the width direction Y of the first leakage suppression portion 20 and is an area where the third joint portion 20Z is not provided.

[0055] At the first upright portion 20Y, the inner end in the width direction Y of the first suppression portion main body 200 is folded back along the longitudinal direction X while winding the elastic member 201. As shown in FIG. 2, the elastic member 201 is provided near the center in the longitudinal direction X of the main body portion 10, and a part of it is fixed in a state of being extended in the longitudinal direction X during manufacturing. The elastic member 201 is released from the force applied to extend the elastic member 201 during manufacturing, and contracts in the longitudinal direction X based on the contraction force (elastic force) of the elastic member 201.

[0056] The material of the elastic member 201 may be any material that is elongated and stretchable. Specifically, as the material of the elastic member 201, a filamentous rubber made of natural rubber, flat rubber, etc., or a thermoplastic elastomer such as urethane, ethylene-vinyl acetate copolymer (EVA), or PE can be used. As the thermoplastic elastomer, polybutadiene, polyisoprene, styrene-butadiene copolymer, styrene-isoprene copolymer, polyurethane, ethylene-vinyl acetate copolymer, ethylene-α-olefin copolymer, etc. can be formed into filaments or formed into films and slit into narrow widths.

[0057] At the inner end of the first suppression part main body 200, the folded belt-shaped region is joined to the opposing first suppression part main body 200. In the first upright part 20Y, the part where the first suppression part main body 200 winds and joins the elastic member 201 constitutes the gather part 25. The gather part 25 has a configuration known as a three-dimensional gather.

[0058] The region where the gather part 25 is formed contracts as the elastic member 201 contracts. Therefore, the first upright part 20Y contracts in the longitudinal direction X of the first upright part 20Y.

[0059] Further, the first leakage suppression part 20 is joined to the non-woven fabric 122 of the main body part 10 with the elastic member 181 sandwiched therebetween at the end A on the head side in the width direction Y of the first leakage suppression part 20. The elastic member 181 is provided along the longitudinal direction X of the main body part 10 and is fixed in a state of being extended in the longitudinal direction X. In the first leakage suppression part 20, the part where the elastic member 181 is sandwiched and joined to the non-woven fabric 122 of the main body part 10 constitutes the first flap part 18. The first flap part 18 is located at the outermost side on the head side A in the width direction Y of the main body part 10 and extends in the longitudinal direction X.

[0060] As the material of the elastic member 181, the same material as that of the elastic member 201 can be used.

[0061] (Second leakage suppression part) The second leakage suppression part 30 is provided on the surface sheet 11 side of the main body part 10. The second leakage suppression part 30 is a strip-shaped member extending along the longitudinal direction X of the main body part 10. Also, the width of the second leakage suppression part 30 is narrower than the width of the first leakage suppression part 20.

[0062] The second leakage suppression part 30 is made of a hydrophobic non-woven fabric and has a second suppression part main body 300 extending in the longitudinal direction X. The non-woven fabric which is the material of the second leakage suppression part 30 may be water-repellent processed.

[0063] The second leakage suppression part 30 has a second joint part 30X which is an area joined to the main body part 10 and a second standing part 30Y which is an area not joined to the main body part 10.

[0064] The second joint part 30X is the end part on the butt side B in the width direction Y of the second leakage suppression part 30 and is an area joined to the main body part 10 (the surface sheet 11 and the back layer 12). The second joint part 30X is provided along the longitudinal direction X at the end part on the butt side B of the second leakage suppression part 30. The joining method may be fusion or adhesion.

[0065] The second standing part 30Y is the end part on the head side A in the width direction Y of the second leakage suppression part 30 and is an area not joined to the main body part 10. The second standing part 30Y is provided along the longitudinal direction X at the end part on the head side A of the second leakage suppression part 30.

[0066] Unlike the first standing part 20Y, the second standing part 30Y does not have an elastic member that contracts the second standing part 30Y in the longitudinal direction.

[0067] Both end parts in the longitudinal direction X of the second standing part 30Y may be weakly joined to the surface sheet 11. In FIG. 2, the weakly joined part is indicated by the reference sign HM.

[0068] A weak joint means that when the force applied to the joint portion is weak (for example, when the force to unfold the folded absorbent article 1 for pets is indirectly transmitted to the joint portion), the joint state is maintained, but when a force exceeding a predetermined value is applied to the joint portion (for example, when the joint portion is in contact with the pet to be worn and a force in the direction of releasing the joint is applied to the joint portion due to the movement of the pet's body), it represents a joint with a strength such that the joint state is released.

[0069] Further, the second leakage prevention part 30 is joined to the non-woven fabric 122 of the main body part 10 with the elastic member 191 sandwiched therebetween at the end part on the buttocks side B in the width direction Y of the second leakage prevention part 30. The elastic member 191 is provided along the longitudinal direction X of the main body part 10 and is fixed in a state of being extended in the longitudinal direction X. In the second leakage prevention part 30, the part where the elastic member 191 is sandwiched and joined to the non-woven fabric 122 of the main body part 10 constitutes the second flap part 19. The second flap part 19 is located on the outermost side in the width direction Y of the main body part 10 (the surface sheet 11 and the back surface layer 12) and extends in the longitudinal direction X.

[0070] As the material of the elastic member 191, the same material as that of the above-described elastic member 201 can be used.

[0071] As shown in FIG. 4, the detailed arrangement of each component in the absorbent article 1 is as follows. In the absorbent article 1, the central axis in the width direction Y is designated as CL1, and the central axis in the longitudinal direction X is designated as CL2. The central part in the longitudinal direction X of the absorbent article 1 refers to the vicinity of the central axis CL2.

[0072] First, in the absorbent article 1, many components are arranged in line symmetry with respect to the central axis CL1 in the width direction Y. The distance A3 from the central axis CL1 to the first joint part 20X is equal to the distance B3 from the central axis CL1 to the second joint part 30X. Also, the length A4 from the first joint part 20X to the end 10x on the head side A in the width direction Y of the main body part 10 is equal to the length B4 from the second joint part 30X to the end 10y on the buttocks side B in the width direction Y of the main body part 10.

[0073] Note that, as shown in FIG. 4, when measuring the distance to the first joint portion 20X, the end 20a of the first joint portion 20X is used as a reference. The end 20a is a boundary formed between the region joined to the main body portion 10 (the first joint portion 20X) and the region not joined to the main body portion 10 (the first standing portion 20Y) in the width direction of the first leakage suppressing portion 20.

[0074] Also, when measuring the distance to the second joint portion 30X, the end 30a of the second joint portion 30X is used as a reference. The end 30a is a boundary formed between the region joined to the main body portion 10 (the second joint portion 30X) and the region not joined to the main body portion 10 (the second standing portion 30Y) in the width direction of the second leakage suppressing portion 30.

[0075] Further, with respect to the central axis CL1 in the width direction Y of the main body portion 10, the absorbers 13 are arranged in line symmetry. That is, the distances from both ends in the width direction of the absorber 13 to the central axis CL1 are equal (A5 = B5). Also, the distances from both ends in the longitudinal direction of the absorber 13 to the central axis CL2 are also equal (C1 = D1).

[0076] However, the first standing portion 20Y and the second standing portion 30Y are not in line symmetry with respect to the central axis CL1. Specifically, at the central portion in the longitudinal direction X of the main body portion 10, the sum of the distance A1 from the head - side end in the width direction Y of the absorber 13 to the first joint portion 20X and the distance A2 from the first joint portion 20X to the inner end 20b of the first standing portion 20Y is longer than the sum of the distance B1 from the butt - side end in the width direction Y of the absorber 13 to the second joint portion 30X and the distance B2 from the second joint portion 30X to the inner end 30b of the second standing portion 30Y. That is, the relational expression (A1 + A2) > (B1 + B2) holds.

[0077] In the absorbent article 1, at the central portion in the longitudinal direction X of the main body portion 10, the distance A1 is equal to the distance B1, and the distance A2 is longer than the distance B2 (A2 > B2).

[0078] Furthermore, in the absorbent article 1, at the central portion in the longitudinal direction X of the main body portion 10, the distance A1 is shorter than the distance A2, and the inner end 20b of the first standing portion 20Y overlaps the absorber 13 in plan view (A2 > A1). Also, in the absorbent article 1, the distance B1 is longer than the distance B2, and the inner end 30b of the second standing portion 30Y does not overlap the absorber 13 in plan view (B1 > B2).

[0079] At this time, at the central portion in the longitudinal direction X of the main body portion 10, the distance A1 may be longer than the distance B1 (A1 > B1). That is, the absorber 13 may be displaced toward the buttocks side B in the main body portion 10.

[0080] Also, in the absorbent article 1, in the width direction Y of the main body portion 10, the distance A6 from the outer end of the third joining portion 20Z to the inner end of the first standing portion 20Y may be shorter than the distance B2 (B2 > A6). The third joining portion 20Z may be continuous with the first joining portion 20X. In this case, the distance A6 is 0.

[0081] When the distance A6 is made shorter than the distance B2, when the absorbent article 1 is folded small at the time of disposal of the absorbent article 1, urine is less likely to leak from the gap between the third joining portion 20Z and the first standing portion 20Y.

[0082] FIG. 5 is an explanatory diagram for explaining the effect of the absorbent article 1, and is a schematic cross-sectional view at the central axis CL2 when the absorbent article 1 is worn by the pet P. The urethral orifice UM of the pet P wearing the absorbent article 1 is, for example, at a position overlapping the absorber 13. The pet P excretes toward the head side A.

[0083] At this time, in the direction of urination, a space surrounded by the first standing portion 20Y and the main body portion 10 is formed to block the urine U. The urine U blocked by the space surrounded by the first standing portion 20Y and the main body portion 10 passes over the absorber 13 in the process of returning rearward (toward the buttocks side B), and thus is effectively absorbed by the absorber 13. Even if a small amount of urine U not absorbed by the absorber 13 exceeds the absorber 13, it is blocked by the second standing portion 30Y.

[0084] Here, since the relational expression (A1 + A2) > (B1 + B2) holds as described above, a relatively larger space is formed on the head side A than on the buttocks side B with respect to the absorber 13, and the excreted urine U can be widely received and blocked. Also, until the urine U is absorbed by the absorber 13, the urine U can be retained in the space surrounded by the first standing portion 20Y and the main body portion 10 even for a short time. Therefore, even if the urine U is excreted forcefully, leakage of urine from the head side A can be suppressed. Also, the urine U can be effectively guided to and absorbed by the absorber 13.

[0085] (Locking portion) FIG. 6 is a rear view of the absorbent article 1. As shown in FIG. 6, the absorbent article 1 has a locking portion 40 at one end side in the longitudinal direction of the main body portion 10. The locking portion 40 is a mechanical fastener. The locking portion 40 connects the front surface sheet 11 and the back surface layer 12 at both ends in the longitudinal direction X of the main body portion 10, and fixes the absorbent article 1 in a cylindrical shape. Thereby, the absorbent article 1 is fixed around the body of the pet P.

[0086] In the present embodiment, the locking portion 40 is provided in the width direction of the back surface layer 12. Therefore, the absorbent article 1 is fixed in a cylindrical shape with the locking portion 40 connected to the front surface sheet 11 by overlapping the front surface of the other end side in the longitudinal direction X on the back surface of one end side in the longitudinal direction X of the main body portion 10. In this way, when the locking portion 40 is provided on the back surface layer 12, the locking portion 40 is exposed to the outside when the absorbent article 1 is worn on the pet P, so that the operator can easily recognize the locking portion 40 and the wearing on the pet P becomes easy.

[0087] The locking portion 40 may be provided on the front surface sheet 11. In this case, the absorbent article 1 is fixed in a cylindrical shape with the locking portion 40 connected to the back surface layer 12 by overlapping the back surface of the other end side in the longitudinal direction X on the front surface of one end side in the longitudinal direction X of the main body portion 10.

[0088] In the absorbent article 1, the central axis CL3 in the width direction Y of the locking portion 40 is located on the side of the second joining portion 30X rather than at the central position (central axis CL1) between the first joining portion 20X and the second joining portion 30X. That is, in the absorbent article 1, the locking portion 40 is provided so as to be relatively displaced toward the buttocks side B. As a result, the absorbent article 1 is fixed on the side closer to the buttocks, and by relatively tightly fastening the side where the second standing portion 30Y (see FIG. 4) is arranged, urine leakage from the rear can be suppressed.

[0089] The region where the locking portion 40 is provided may be uniformly formed, or the configuration in the thickness direction (z direction) may differ depending on the region. In the absorbent article 1 having such a configuration, the rigidity of the region where the locking portion 40 is provided varies depending on the location, and it has a high-rigidity region with relatively high rigidity.

[0090] For example, when the locking portion 40 is provided so as to be displaced toward the head side A, a part of the head side A of the locking portion 40 overlaps the first leakage suppression portion 20 in a planar manner, and the rest does not overlap the first leakage suppression portion 20. Similarly, when the locking portion 40 is provided so as to be displaced toward the buttocks side B, a part of the buttocks side B of the locking portion 40 overlaps the second leakage suppression portion 30 in a planar manner, and the rest does not overlap the second leakage suppression portion 30 in a planar manner. Due to such a difference in the configuration in the thickness direction, a difference in rigidity occurs in the region where the locking portion 40 is provided.

[0091] In the above example, the region where the locking portion 40 overlaps the first leakage suppression portion 20 or the second leakage suppression portion 30 has relatively higher rigidity than the other non-overlapping regions. Such a region with high rigidity corresponds to the "high-rigidity region" in the present invention.

[0092] When the pet P wearing the absorbent article 1 moves, forces are applied to the absorbent article 1 from a plurality of directions, and it may be pulled, displaced in position, or the end portion may be turned up. If the locking portion 40 has a high-rigidity region, the high-rigidity region is less likely to deform than a region with relatively low rigidity (low-rigidity region), and it is possible to suppress the displacement of the absorbent article 1 and the turning up of the end portion around the high-rigidity region.

[0093] Furthermore, the high-rigidity region may be formed by changing the configuration of the locking portion 40 itself. That is, the locking portion may have portions with relatively different rigidities instead of being uniformly formed.

[0094] Figs. 7 to 9 are explanatory views showing modified examples of the locking portion. In the following description, in the locking portion, a portion with relatively high rigidity is defined as the high-rigidity portion. Also, in the following description, in the region where the locking portion is provided, the configuration in the thickness direction of the absorbent article 1 is assumed to be uniform. That is, the region where the high-rigidity portion of the locking portion is located corresponds to the high-rigidity region.

[0095] In the locking portion 40A shown in Fig. 7, the high-rigidity portion 40x is located on the head side A in the width direction Y, and the relatively low-rigidity low-rigidity portion 40y is located on the tail side B. When the pet P wearing the absorbent article 1 walks, the head side A of the absorbent article 1 is less likely to move than the tail side B. Therefore, by providing the high-rigidity portion 40x on the head side A, displacement of the absorbent article 1 can be suppressed and it can be firmly fixed to the body.

[0096] On the other hand, the pet P moves while swinging its hips from side to side when walking. In this case, by providing the low-rigidity portion 40y on the tail side B, the absorbent article 1 worn by the pet P can flexibly follow the movement of the body and displacement can be suppressed.

[0097] In the locking portion 40B shown in Fig. 8, the high-rigidity portion 40x is located on the tail side B in the width direction Y, and the relatively low-rigidity low-rigidity portion 40y is located on the head side A. When attaching the absorbent article 1, first, the rear end portion of the absorbent article 1 is pressed against the tail of the pet P for positioning, and then the first flap portion 18 and the second flap portion 19 are spread and fitted. At that time, if there is a high-rigidity portion 40x on the tail side B, displacement can be suppressed when spreading the flap portion to fit the absorbent article 1.

[0098] The locking portion 40C shown in Fig. 9 has a high-rigidity portion 40x positioned near the center in the width direction Y, and low-rigidity portions 40y are positioned on both the head side A and the tail side B of the high-rigidity portion 40x. When the high-rigidity portion 40x is positioned near the tip of the genitals of the pet P when wearing the absorbent article 1, the genitals can be fixed by the high-rigidity portion 40x, and even if the absorbent article 1 shifts to the tail side B, it is difficult for the genitals to be exposed.

[0099] (Discoloring portion) As shown in Fig. 6, the absorbent article 1 has a discoloring portion 50 that reacts with urine and changes color. The discoloring portion 50 is provided on the back surface layer 12. The discoloring portion 50 is in the form of a strip-shaped region extending in the longitudinal direction X, but is not limited to this and various designs can be applied. By checking the discoloration of the discoloring portion 50, the user can recognize a guideline for the replacement timing of the absorbent article 1.

[0100] The discoloring portion 50 is preferably positioned on the side of the second joint portion 30X rather than at the center position (central axis CL1) between the first joint portion 20X and the second joint portion 30X. As described above, when the pet P wearing the absorbent article 1 excretes urine U, the urine U is first blocked by the first standing portion 20Y (see Fig. 4) on the head side A, and then absorbed by the absorbent body 13 while returning to the tail side B. That is, the absorbent body 13 is initially more likely to absorb urine U on the head side A and later more likely to absorb urine U on the tail side B. Therefore, when the discoloring portion 50 positioned on the side of the second joint portion 30X rather than the central axis CL1 changes color, it can be determined that the absorbent body 13 on the head side A of the discoloring portion 50 is also absorbing urine U, making it easier to make a reasonable judgment that replacement is necessary.

[0101] (Marking portion) The absorbent article 1 has a marking portion 60. The marking portion 60 is a strip-shaped printed pattern provided on the back surface layer 12. The marking portion 60 indicates the position of the end of the main body portion 10 in a state where the main body portion 10 is fixed by the locking portion 40. In the absorbent article 1, the surface sheet 11 of the other end 10z in the longitudinal direction X of the main body portion 10 is overlapped and fixed to the locking portion 40 in a cylindrical shape, and the marking portion 60 indicates the position of the other end 10z.

[0102] When the user attaches the absorbent article 1 to the pet P, by positioning the other end 10z along the marking portion 60, the absorbent article 1 can be used in an appropriate posture.

[0103] The marking portion 60 has a first marking portion 60a located on the head side A in the width direction Y of the back surface layer 12 and a second marking portion 60b located on the buttocks side B. In the present embodiment, the first marking portion 60a and the second marking portion 60b are continuously band-shaped and form the marking portion 60. The first marking portion 60a and the second marking portion 60b may be separated from each other.

[0104] The second marking portion 60b is located inside the main body portion 10 in the longitudinal direction X with respect to the first marking portion 60a. That is, the band-shaped marking portion 60 intersects obliquely with the central axis CL1.

[0105] In the absorbent article 1, by aligning the other end 10z of the main body portion 10 along the marking portion 60 as described above and fixing it with the locking portion 40, the absorbent article 1 becomes a weight-like shape that tightens the buttocks side B more than the head side A. As a result, it becomes easier to attach the absorbent article 1 to the pet P with the buttocks side B where the second standing portion 30Y is arranged tightened, and it becomes easier to suppress urine leakage from the buttocks side B.

[0106] According to the absorbent article 1 having the above configuration, urine leakage from the front leg side can be suppressed.

[0107] (Modification example) FIG. 10 is a schematic view showing a modification example of the present embodiment, and is a schematic plan view showing the central portion in the longitudinal direction.

[0108] The absorbent article 2 shown in FIG. 10 has an absorbent body 15. The absorbent body 15 is convex in the direction of the second leakage suppressing portion 30 at the central portion in the longitudinal direction X of the main body portion 10. That is, the absorbent body 15 has a first portion 151 that is rectangular in plan view and a second portion 152 that is convex in the direction of the second leakage suppressing portion 30.

[0109] In the absorbent article 2, the inner end 30b of the second standing portion 30Y overlaps with the second portion 152 of the absorbent body 15 in plan view.

[0110] As described above, when the pet P wearing the absorbent article urinates toward the head side A, the urine U is blocked by the first standing portion 20Y and is absorbed by the absorbent body 13 in the process of returning rearward (buttocks side B). Here, if the amount of the excreted urine U is large or the force of excretion is strong, there is a possibility that a large amount of urine U that cannot be completely absorbed by the absorbent body 13 may exceed the absorbent body 13.

[0111] Even in such a case, when the absorbent body 15 extends to the vicinity of the second standing portion 30Y as in the absorbent article 2, the opportunity for the absorbent body 15 to absorb the urine U increases, the urine U is easily absorbed, and it is easy to suppress urine leakage from the buttocks side B.

[0112] Even with the absorbent article 2 having the above-described configuration, urine leakage from the front leg side can be suppressed. Furthermore, urine leakage from the hind leg side can also be suppressed.

[0113] As described above, the preferred embodiments according to the present invention have been described with reference to the accompanying drawings, but the present invention is not limited to such examples. The various shapes, combinations, etc. of the respective constituent members shown in the above-described examples are merely examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present invention.
