Description

Technical Field

[0001] This invention relates to an absorbent article for pets.

[0002] This application claims priority based on Japanese Patent Application No. 2020-146100, filed on August 31, 2020, the contents of which are incorporated herein by reference. Background Technology

[0003] Conventionally, as items for collecting urine excreted by pets, especially dogs and cats, there are known absorbent strips that are worn around the pet's waist without covering the entire buttocks (e.g., Patent Document 1). The absorbent strip described in Patent Document 1 collects excreted urine in its absorbent body by being worn in a manner that covers the pet's urethral opening. Therefore, even if marking is done according to the dog's habits, for example, soiling caused by urine can be suppressed.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2007-020533 Summary of the Invention

[0007] The problem the invention aims to solve

[0008] In the absorbent article described in Patent Document 1 above, in order to suppress urine leakage, strip-shaped three-dimensional pleats are provided on both sides of the surface in contact with the pet's torso, namely the foreleg side and the hind leg side. When a male pet urinates from the urethra toward the foreleg side, the three-dimensional pleats on the foreleg side receive the excreted urine and return it to the absorbent side, thereby assisting in the collection of urine.

[0009] However, since some pets urinate forcefully towards their front legs, and the pleats may shift depending on the urination posture, urine may sometimes leak from the pleats on the front legs side. Therefore, it is important to seek improvement.

[0010] The present invention was made in view of the following circumstances, and its object is to provide an absorbent pet product that suppresses leakage of urine from the front leg side.

[0037] Figure 10 This is a schematic diagram illustrating a variation of this embodiment. Detailed Implementation

[0038] The following is for reference Figures 1-10 This description explains the absorbent article for pets according to this embodiment. Additionally, in all the following drawings, the dimensions and proportions of the constituent elements are appropriately varied for ease of observation. Furthermore, in the following description, the absorbent article for pets will sometimes be simply referred to as "absorbent article".

[0039] Figure 1 This is a schematic diagram showing the wearing state of the pet absorbent article 1 according to this embodiment. The absorbent article 1 is suitable for use with male pets. The absorbent article 1 absorbs and retains the liquid excreted from the pet P internally. The liquid to be absorbed refers to the liquid excreted from the body of the pet P, typically including urine excreted by the pet P. In addition, blood and semen may also be included. Hereinafter, urine will be used as an example of the liquid to be absorbed to describe the absorbent article 1.

[0040] In the following description, an example of a dog wearing absorbent item 1 is shown, but other pets can also wear absorbent item 1. For example, a cat can also wear absorbent item 1.

[0041] The absorbent article 1 of this embodiment has a strip-like shape and has mutually orthogonal length, width, and thickness directions. For example... Figure 1As shown, the absorbent item 1 is worn along the waist of the pet P in the length direction, and is wrapped around the waist H of the pet P in front of the thigh T (head side).

[0042] In this embodiment, "strip-shaped" is a description of a situation where it extends relatively long in one direction. In this sense, the "shape of the strip" is not limited to a mathematical rectangle, and the shape of the sides does not have to be a straight line.

[0043] When the absorbent item 1 is worn in this position, the absorbent item 1 covers the urethral opening of the pet P and can absorb and retain the urine excreted by the pet P.

[0044] In the following description, the side of the absorbent item 1 that faces the pet P when worn will be referred to as the "front" and the side that faces outwards from the pet P when worn will be referred to as the "back".

[0045] Figure 2 This is a schematic perspective view of the absorbent article 1 according to this embodiment. Figure 3 yes Figure 2 The dissected view under the cross-sectional field of view shown by line segment III-III. Figure 4 This is a top view of absorbent item 1.

[0046] In the following description, an orthogonal xyz coordinate system is established, and the positional relationships of each component are explained with reference to this orthogonal xyz coordinate system. Here, a predetermined direction in the horizontal plane is set as the x-axis direction, a direction orthogonal to the x-axis direction in the horizontal plane is set as the y-axis direction, and a direction orthogonal to both the x-axis and y-axis directions (i.e., the vertical direction) is set as the z-axis direction.

[0047] like Figure 2 , Figure 3 As shown, the absorbent article 1 of this embodiment has a main body 10, a first leakage suppression part 20 and a second leakage suppression part 30 that are a pair.

[0048] In absorbent material 1, Figure 1 In the wearing state shown, the head side of pet P is indicated by the attached figure label A, and the buttock side of pet P is indicated by the attached figure label B.

[0049] (Main Body)

[0050] The main body 10 has a strip-like appearance extending along the x-axis direction. The length of the main body 10 in the y-axis direction is shorter than its length in the x-axis direction. The x-axis direction corresponds to the "length direction" in this invention. Furthermore, the y-axis direction corresponds to the "width direction" in this invention. Furthermore, the z-axis direction corresponds to the "thickness direction" in this invention.

[0051] The reference numeral X indicates the length direction of the main body 10, and the reference numeral Y indicates the width direction of the main body 10.

[0052] The main body 10 has a surface sheet 11, a back layer 12, and an absorber 13. The surface sheet 11, the back layer 12, and the absorber 13 are stacked along the thickness direction (z-axis direction).

[0053] The surface sheet 11 is located on the front side 10a of the main body 10, forming the front side 10a of the main body 10.

[0054] The surface sheet 11 allows liquid (pet P's urine) to pass through. The surface sheet 11 is made of, for example, nonwoven fabric.

[0055] The back layer 12 is located on the back side 10b of the main body 10, forming the back side 10b of the main body 10. The back layer 12 does not allow liquid (pet P's urine) to pass through.

[0056] The back layer 12 has a waterproof membrane 121 that prevents pet P's urine from penetrating and a nonwoven fabric 122 located on the outer side of the waterproof membrane 121. Printing can also be performed on the back side surface 121a of the waterproof membrane 121. Furthermore, printing can also be performed on the nonwoven fabric 122.

[0057] exist Figure 3 In the absorbent article 1 shown, the length of the surface sheet 11 in the width direction is the same as the length of the waterproof membrane 121 in the width direction. Furthermore, the length of the nonwoven fabric 122 in the width direction is longer than both the length of the surface sheet 11 and the length of the waterproof membrane 121 in the width direction. The nonwoven fabric 122 completely covers the surface sheet 11 and the waterproof membrane 121 in the field of view viewed from the back.

[0058] Absorbent 13 is disposed between the surface sheet 11 and the back layer 12. Absorbent 13 absorbs liquid (pet P's urine). Figure 2 As shown, the absorbent 13 extends along the length direction X of the absorbent article 1 and is positioned at the center of the absorbent article in the length direction X. The length of the absorbent 13 in the width direction Y is shorter than the length of the absorbent 13 in the length direction X.

[0059] The absorbent body 13, as the absorbent body of an absorbent item for pets, can adopt a known structure. For example, the absorbent body 13 has a core made of absorbent raw material and a covering material covering the core, and is a component that is rectangular in plan view.

[0060] Examples of absorbent raw materials include fluff pulp and highly absorbent polymers. Examples of fluff pulp include chemical pulp, cellulose fibers, rayon, cellulose acetate, and other artificial cellulose fibers. Examples of highly absorbent polymers include starch-based, acrylic-based, and amino acid-based granular or fibrous polymers.

[0061] Examples of the covering material include a non-woven fabric covering material and a cotton paper covering material.

[0062] (First Leakage Suppression Portion)

[0063] The first leakage suppression portion 20 is provided on the surface sheet 11 side of the main body portion 10. The first leakage suppression portion 20 is a strip-shaped member extending along the length direction X of the main body portion 10.

[0064] The first leakage suppression portion 20 includes a first suppression portion main body 200 made of a hydrophobic non-woven fabric and extending along the length direction X, and an elastic member 201 installed along the length direction of the first suppression portion main body 200. The non-woven fabric used as the material of the first leakage suppression portion 20 may also be subjected to waterproof treatment.

[0065] The first suppression portion main body 200 is joined to the main body portion 10 (the surface sheet 11 and the back layer 12) along the length direction X at the end portion on the head side A in the width direction Y of the main body portion 10. The joining method can be either welding or bonding.

[0066] In addition, in the following description, an "end portion" refers to an area including a certain range, and this certain range includes the edge of an article.

[0067] Furthermore, an "end" refers to the edge of an article. The same applies to "one end" and "the other end".

[0068] The first leakage suppression portion 20 has a first joining portion 20X as an area joined to the main body portion 10 and a first standing portion 20Y as an area not joined to the main body portion 10.

[0069] The first joining portion 20X is the end portion on the head side A in the width direction Y of the first leakage suppression portion 20 and is an area joined to the main body portion 10 (the surface sheet 11 and the back layer 12). The first joining portion 20X is provided along the length direction X at the end portion on the head side A of the first leakage suppression portion 20. The joining method can be either welding or bonding.

[0070] The first standing portion 20Y is the end portion on the hip side B 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 standing portion 20Y is provided along the length direction X at the end portion on the hip side B of the first leakage suppression portion 20.

[0071] And, as Figure 4 shown, the first leakage suppression portion 20 may also be provided with a third joining portion 20Z joined to the surface sheet 11. In the present embodiment, the third joining portion 20Z is provided at the end portions on the hip side B in the width direction Y of the first leakage suppression portion 20 and at both ends in the length direction X.

[0072] When the first leakage suppression part 20 is engaged with the surface sheet 11 at the third joint 20Z, the range of the first erected part 20Y refers to the end of the butt side B of the first leakage suppression part 20 in the width direction Y and is the area where the third joint 20Z is not provided.

[0073] In the first erecting part 20Y, the inner end of the first restraining part body 200 in the width direction Y is folded back along the length direction X while being wound into the elastic member 201. Figure 2 As shown, the elastic member 201 is located near the center of the main body 10 in the length direction X, and is partially fixed during manufacturing in a state of elongation along the length direction X. The elastic member 201 is released from the force applied during manufacturing to elongate the elastic member 201, and contracts along the length direction X based on the contractile force (elastic force) of the elastic member 201.

[0074] The material of the elastic member 201 can be a slender and stretchable material. Specifically, the material of the elastic member 201 can be linear rubber or flat rubber formed from natural rubber, or thermoplastic elastomers such as polyurethane, ethylene-vinyl acetate copolymer (EVA), and PE. Examples of thermoplastic elastomers include elastomers formed by molding polybutadiene, polyisoprene, styrene-butadiene copolymer, styrene-isoprene copolymer, polyurethane, ethylene-vinyl acetate copolymer, and ethylene-α-olefin copolymer into linear or film shapes and then cutting them into thinner sections.

[0075] The inner end of the first restraining part body 200, which is a folded-back strip-shaped area, joins with the opposing first restraining part body 200. In the first erecting part 20Y, the portion formed by winding the first restraining part body 200 into the elastic member 201 and joining it constitutes the pleated part 25. The pleated part 25 is a structure known as a three-dimensional pleat.

[0076] The area where the pleats 25 are formed contracts as the elastic member 201 contracts. Therefore, the first upright portion 20Y contracts along the length direction X of the first upright portion 20Y.

[0077] Furthermore, the first leakage suppression part 20 is joined to the nonwoven fabric 122 of the main body 10 at its head side A in the width direction Y, with an elastic member 181 sandwiched between it and the nonwoven fabric 122 of the main body 10. The elastic member 181 is provided along the length direction X of the main body 10 and is fixed in a state of elongation along the length direction X. In the first leakage suppression part 20, the portion joined to the nonwoven fabric 122 of the main body 10 through the elastic member 181 constitutes the first wing 18. The first wing 18 is located at the outermost side A of the head side of the main body 10 in the width direction Y and extends along the length direction X.

[0078] The material of elastic member 181 can be the same as that of elastic member 201.

[0079] (Second Leakage Suppression Unit)

[0080] 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 length direction X of the main body part 10. Furthermore, the width of the second leakage suppression part 30 is narrower than the width of the first leakage suppression part 20.

[0081] The second leakage suppression part 30 has a second suppression part body 300 made of hydrophobic nonwoven fabric and extending along the length direction X. The nonwoven fabric used as the material of the second leakage suppression part 30 may also be waterproofed.

[0082] The second leakage suppression part 30 has a second joining part 30X as a region that joins with the main body part 10 and a second standing part 30Y as a region that does not join with the main body part 10.

[0083] The second joint 30X is the end of the second leakage suppression part 30 on its hip side B in the width direction Y, and is the area that joins with the main body part 10 (surface sheet 11 and back layer 12). The second joint 30X is provided along the length direction X at the end of the second leakage suppression part 30 on its hip side B. The joining method can be either welding or bonding.

[0084] The second erected portion 30Y is the end of the head side A of the second leakage suppression portion 30 in the width direction Y, and is the area that is not joined to the main body portion 10. The second erected portion 30Y is provided along the length direction X at the end of the head side A of the second leakage suppression portion 30.

[0085] The second erected part 30Y differs from the first erected part 20Y in that it does not have an elastic member that causes the second erected part 30Y to contract along its length.

[0086] The two ends of the second upright portion 30Y in the length direction X can also be weakly joined to the surface plate 11. Figure 2 In the figure, the part that has been weakly joined is indicated by the reference numeral HM.

[0087] A weak joint means a joint that is performed with a strength such that the joint is maintained when a weak force is applied to the joint (e.g., when a force of the same magnitude as when unfolding a folded pet with an absorbent article 1 is indirectly transmitted to the joint), but the joint is released when a predetermined or greater force is applied to the joint (e.g., when a force in the direction of release is applied to the joint due to the movement of the pet's body while the joint is in contact with the pet being worn).

[0088] Furthermore, the end of the second leakage suppression part 30 on its hip side B in the width direction Y is engaged with the nonwoven fabric 122 of the main body 10 in a state where an elastic member 191 is sandwiched between the nonwoven fabric 122 and the main body 10. The elastic member 191 is provided along the length direction X of the main body 10 and is fixed in a state of elongation along the length direction X. In the second leakage suppression part 30, the portion engaged with the nonwoven fabric 122 of the main body 10 through the elastic member 191 constitutes the second wing 19. The second wing 19 is located at the outermost side of the main body 10 (surface sheet 11 and back layer 12) in the width direction Y and extends along the length direction X.

[0089] The material of elastic member 191 can be the same as the material of elastic member 201 described above.

[0090] like Figure 4 As shown, the detailed configuration of each structure of 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 length direction X is designated as CL2. The central part in the length direction X of the absorbent article 1 refers to the vicinity of the central axis CL2.

[0091] First, most of the structure of the absorbent article 1 is symmetrically arranged with respect to the central axis CL1 in the width direction Y. The distance A3 from the central axis CL1 to the first joint 20X is equal to the distance B3 from the central axis CL1 to the second joint 30X. Furthermore, the length A4 from the first joint 20X to the head-side A end 10x in the width direction Y of the main body 10 is equal to the length B4 from the second joint 30X to the hip-side B end 10y in the width direction Y of the main body 10.

[0092] In addition, such as Figure 4 As shown, when measuring the distance between the first joint portion 20X and the first joint portion 20X, the end 20a of the first joint portion 20X is used as a reference. The end 20a is the boundary formed in the width direction of the first leakage suppression portion 20 between the area that joins with the main body portion 10 (the first joint portion 20X) and the area that does not join with the main body portion 10 (the first erect portion 20Y).

[0093] Furthermore, when measuring the distance between the second joint portion 30X and the second joint portion 30X, the end 30a of the second joint portion 30X is used as a reference. The end 30a is the boundary formed in the width direction of the second leakage suppression portion 30 between the area that joins with the main body portion 10 (the second joint portion 30X) and the area that does not join with the main body portion 10 (the second erect portion 30Y).

[0094] Furthermore, the absorber 13 is arranged symmetrically with respect to the central axis CL1 in the width direction Y of the main body 10. That is, the distances from both ends of the absorber 13 in the width direction to the central axis CL1 are equal (A5 = B5). In addition, the distances from both ends of the absorber 13 in the length direction to the central axis CL2 are also equal (C1 = D1).

[0095] However, the first upright portion 20Y and the second upright portion 30Y are not symmetrical with respect to the central axis CL1. Specifically, at the center of the main body portion 10 in the length direction X, the sum of the distance A1 from the head-side end of the absorber 13 in the width direction Y to the first joint portion 20X and the distance A2 from the first joint portion 20X to the inner end 20b of the first upright portion 20Y is greater than the sum of the distance B1 from the hip-side end of the absorber 13 in the width direction Y to the second joint portion 30X and the distance B2 from the second joint portion 30X to the inner end 30b of the second upright portion 30Y. That is, the relationship (A1 + A2) > (B1 + B2) holds.

[0096] In the absorbent article 1, at the center of the main body 10 along the length direction X, the distance A1 is equal to the distance B1, and the distance A2 is longer than the distance B2 (A2 > B2).

[0097] Furthermore, in the absorbent article 1, at the center of the main body 10 along the length direction X, the distance A1 is shorter than the distance A2, and the inner end 20b of the first upright portion 20Y overlaps with the absorbent body 13 when viewed from above (A2 > A1). Additionally, in the absorbent article 1, the distance B1 is longer than the distance B2, and the inner end 30b of the second upright portion 30Y does not overlap with the absorbent body 13 when viewed from above (B1 > B2).

[0098] At this time, the distance A1 at the center of the main body 10 in the length direction X can also be longer than the distance B1 (A1 > B1). That is, the absorber 13 can also be disposed offset from the main body 10 towards the hip side B.

[0099] Furthermore, in the absorbent article 1, the distance A6 from the outer end of the third joint 20Z to the inner end of the first upright portion 20Y in the width direction Y of the main body portion 10 may be shorter than the distance B2 (B2 > A6). The third joint 20Z may also be continuous with the first joint 20X. In this case, the distance A6 is 0.

[0100] If the distance A6 is made shorter than the distance B2, urine will not easily leak from the gap between the third joint 20Z and the first upright part 20Y when the absorbent article 1 is stacked smaller when it is discarded.

[0101] Figure 5This is an explanatory diagram illustrating the effect of absorbent item 1, and is a schematic cross-sectional view at the central axis CL2 when pet P is wearing absorbent item 1. The urethral opening UM of pet P wearing absorbent item 1 is, for example, overlapping with absorbent body 13. Pet P excretes towards its head side A.

[0102] At this time, a space formed by the first upright portion 20Y and the main body portion 10 is created in the direction of urination, blocking the urine U. The urine U blocked by the space formed by the first upright portion 20Y and the main body portion 10 passes through the absorber 13 as it returns backward (to the buttock side B), and is therefore effectively absorbed by the absorber 13. Even if a small amount of urine U is not absorbed by the absorber 13, it will be blocked by the second upright portion 30Y.

[0103] Here, because the relationship (A1 + A2) > (B1 + B2) holds as described above, a relatively larger space is formed at a position closer to the head (A) of the absorbent body 13 than at the buttock (B), allowing for a wider range of reception and blocking of excreted urine U. Furthermore, before the urine U is absorbed by the absorbent body 13, the space enclosed by the first upright portion 20Y and the main body portion 10 can retain the urine U for a relatively short period. Therefore, even with sudden excretion of urine U, leakage from the head (A) can be suppressed. Moreover, the urine U can be effectively guided to the absorbent body 13 for absorption.

[0104] (Card fixing section)

[0105] Figure 6 This is the rear view of absorbent item 1. (Example) Figure 6 As shown, the absorbent article 1 has a locking part 40 at one end of the main body 10 along its length. The locking part 40 is a mechanical fastener. The locking part 40 connects the surface sheet 11 and the back layer 12 at both ends of the main body 10 along its length X, fixing the absorbent article 1 into a cylindrical shape. Thus, the absorbent article 1 is fixed to the waist of the pet P.

[0106] In this embodiment, the locking part 40 is provided along the width direction of the back layer 12. Therefore, the absorbent article 1 is fixed into a cylindrical shape by overlapping the front side of the other end of the main body part 10 in the length direction X with the back side of one end in the length direction X, thereby connecting the locking part 40 to the surface sheet 11. Since the locking part 40 is provided in the back layer 12 in this way, the locking part 40 is exposed on the outside when worn on the pet P, so the worker can easily identify the locking part 40, and it is easier to wear on the pet P.

[0107] The locking part 40 may also be provided on the surface sheet 11. In this case, the absorbent article 1 is fixed into a cylindrical shape by connecting the locking part 40 to the back layer 12 by overlapping the back side of the other end side of the main body part 10 in the length direction X with the front side of one end side in the length direction X.

[0108] In the absorbent article 1, the central axis CL3 of the locking part 40 in the width direction Y is located closer to the second joint 30X than the center position (central axis CL1) between the first joint 20X and the second joint 30X. That is, in the absorbent article 1, the locking part 40 is offset relative to the buttock side B. As a result, the absorbent article 1 is fixed on the side closer to the buttocks, and the second upright part 30Y (see reference) is provided. Figure 4 One side is tightened relatively tightly, which can suppress leakage of urine from the rear.

[0109] The region with the locking portion 40 can be formed in the same way, but the structure in the thickness direction (z direction) can vary depending on the region. In such an absorbent article 1, the stiffness of the region with the locking portion 40 varies depending on the location, and there are high-stiffness regions with relatively high stiffness.

[0110] For example, when the locking part 40 is offset towards the head side A, a portion of the head side A of the locking part 40 overlaps planarly with the first leakage suppression part 20, while the remaining portion does not overlap planarly with the first leakage suppression part 20. Similarly, when the locking part 40 is offset towards the hip side B, a portion of the hip side B of the locking part 40 overlaps planarly with the second leakage suppression part 30, while the remaining portion does not overlap planarly with the second leakage suppression part 30. Due to this difference in the structure along the thickness direction, a difference in stiffness is generated in the region where the locking part 40 is provided.

[0111] In the above example, the area where the locking part 40 overlaps with the first leakage suppression part 20 or the second leakage suppression part 30 has relatively higher stiffness compared to the other non-overlapping areas. Such a high-stiffness area corresponds to the "high-stiffness area" in this invention.

[0112] When a pet P wearing absorbent item 1 moves, forces are applied to absorbent item 1 from multiple directions, sometimes causing it to be pulled and misaligned or its ends to curl up. If the locking part 40 has a high-rigidity area, the high-rigidity area is less prone to deformation compared to the relatively low-rigidity area (low-rigidity area), and can suppress the misalignment of absorbent item 1 and the curling up of the ends around the high-rigidity area.

[0113] Furthermore, high-stiffness regions can also be formed by modifying the structure of the locking part 40 itself. That is, the locking parts can not be formed in the same way, but can have parts with relatively different stiffness.

[0114] Figures 7-9This is an explanatory diagram showing a modified example of the locking part. In the following description, the portion of the locking part with relatively high stiffness is designated as a high-stiffness portion. Furthermore, in the following description, the structure of the absorbent article 1 in the thickness direction is the same in the region where the locking part is provided. That is, the region where the high-stiffness portion of the locking part is located corresponds to a high-stiffness region.

[0115] exist Figure 7 In the locking part 40A shown, the high-stiffness part 40x is located on the head side A in the width direction Y, and the low-stiffness part 40y, with relatively lower stiffness, is located on the hip side B. When a pet P wearing the absorbent material 1 walks, the head side A of the absorbent material 1 is less prone to movement compared to the hip side B. Therefore, by providing the high-stiffness part 40x on the head side A, misalignment of the absorbent material 1 can be suppressed, and it can be securely fixed to the body.

[0116] On the other hand, the pet P moves by swaying its hips from side to side while walking. In this case, by setting a low-stiffness part 40y on the hip side B, the absorbent material 1 worn by the pet P can flexibly follow the movement of the body and suppress misalignment.

[0117] exist Figure 8 In the locking part 40B shown, the high-rigidity part 40x is located on the hip side B in the width direction Y, and the low-rigidity part 40y, with relatively lower rigidity, is located on the head side A. When wearing the absorbent item 1, the rear end of the absorbent item 1 is first pressed against the tail of the pet P for positioning, and then the first wing 18 and the second wing 19 are unfolded to make it fit snugly. At this time, if the high-rigidity part 40x is present on the hip side B, misalignment can be suppressed when the wings are unfolded to make the absorbent item 1 fit snugly.

[0118] exist Figure 9 In the locking part 40C shown, the high-rigidity part 40x is located near the center in the width direction Y, and the low-rigidity part 40y is located on both sides of the high-rigidity part 40x, namely the head side A and the buttock side B. If the high-rigidity part 40x is located near the front end of the pet P's genitals when the absorbent item 1 is worn, the genitals can be fixed by the high-rigidity part 40x, and the genitals will not be easily exposed even if the absorbent item 1 shifts to the buttock side B.

[0119] (Color-changing section)

[0120] like Figure 6 As shown, the absorbent article 1 has a color-changing portion 50 that reacts with urine to change color. The color-changing portion 50 is provided on the back layer 12. The color-changing portion 50 is provided as a strip-shaped area extending along the length direction X, but is not limited to this, and various designs can be implemented. By observing the color change of the color-changing portion 50, the user can identify the standard for when the absorbent article 1 should be replaced.

[0121] The color-changing portion 50 is preferably positioned closer to the second joint 30X than the center position (central axis CL1) between the first joint 20X and the second joint 30X. As described above, if the pet P wearing the absorbent material 1 urinates U, the urine U is first absorbed by the first upright portion 20Y on the head side A (refer to...). Figure 4 The urine is intercepted and then returns to the buttock side B and is absorbed by the absorbent body 13. That is, the absorbent body 13 initially readily absorbs urine U on the head side A, and then readily absorbs urine U on the buttock side B. Therefore, if the discolored portion 50, located on the side closer to the second joint 30X than the central axis CL1, changes color, it can be determined that the absorbent body 13 on the head side A, which is closer to the discolored portion 50, has also absorbed urine U, making it easy to determine that it should be replaced.

[0122] (Marking section)

[0123] The absorbent article 1 has a marking portion 60. The marking portion 60 is a strip-shaped printed pattern provided on the back layer 12. The marking portion 60 indicates the position of the end of the main body 10 when the main body 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 10 is overlapped with the locking portion 40 and fixed into a cylindrical shape, and the marking portion 60 indicates the position of the other end 10z.

[0124] When the user wears the absorbent item 1 on the pet P, the other end 10z is positioned along the marking part 60, so that the absorbent item 1 can be used in an appropriate posture.

[0125] The marking portion 60 has a first marking portion 60a located on the head side A in the width direction Y of the back layer 12 and a second marking portion 60b located on the buttock side B. In this embodiment, the first marking portion 60a and the second marking portion 60b are continuous in a strip to form the marking portion 60. The first marking portion 60a and the second marking portion 60b may also be separate.

[0126] The second marking portion 60b is located inside the main body portion 10 in the longitudinal direction X, compared to the first marking portion 60a. That is, the strip-shaped marking portion 60 intersects the central axis CL1 at an angle.

[0127] In the absorbent article 1, by fixing the other end 10z of the main body 10 along the marking portion 60 as described above and using the locking portion 40, the absorbent article 1 becomes a spindle shape that tightens the buttock side B compared to the head side A. Therefore, with the buttock side B, where the second upright portion 30Y is located, tightened, it is easy to wear the absorbent article 1 on the pet P, and it is easy to suppress urine leakage from the buttock side B.

[0128] The absorbent material 1 with the structure described above can suppress urine leakage from the front leg side.

[0129] (Variation example)

[0130] Figure 10 This is a schematic diagram showing a modified example of this embodiment, and is a schematic top view showing the central portion in the length direction.

[0131] Figure 10 The absorbent article 2 shown has an absorbent body 15. The absorbent body 15 protrudes from the center of the main body portion 10 in the longitudinal direction X toward the direction of the second leakage suppression portion 30. That is, the absorbent body 15 has a first portion 151 that is rectangular in plan view and a second portion 152 that protrudes toward the direction of the second leakage suppression portion 30.

[0132] In the absorbent article 2, the inner end 30b of the second upright part 30Y overlaps with the second part 152 of the absorbent body 15 when viewed from above.

[0133] As described above, if a pet P wearing an absorbent material urinates towards its head (A), the urine U is blocked by the first upright part 20Y and absorbed by the absorbent body 13 as it returns backward (to the buttocks (B)). Here, if the amount of urine U excreted is large or the excretion is forceful, a large amount of urine U that is not completely absorbed by the absorbent body 13 may pass over the absorbent body 13.

[0134] In such a case, if the absorbent body 15 extends to the vicinity of the second upright part 30Y as in absorbent article 2, the chance of the absorbent body 15 absorbing urine U increases, making it easier to absorb urine U and easier to suppress leakage of urine from the buttock side B.

[0135] Even absorbent materials 2 with the structure described above can suppress urine leakage from the front leg side. Furthermore, they can also suppress urine leakage from the hind leg side.

[0136] The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to these examples. The shapes, combinations, etc. of the constituent components shown in the above examples are just examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present invention.
