[0051] [1st Embodiment]

[0052] Hereinafter, a pet use absorbent article of the 1st embodiment of the present application will be described with reference to Figures 1 to 14 A pet use absorbent article of the 1st embodiment of the present application will be described. In all the drawings hereinafter, the size, the ratio, and the like of each constituent element are appropriately different so as to facilitate observation of the drawings. Further, in the following description, the pet use absorbent article will be sometimes referred to simply as "absorbent article".

[0053] Figure 1 is a schematic view showing a wearing state of the pet use absorbent article 1 of the present embodiment. The absorbent article 1 is suitable for use with a male pet. The absorbent article 1 absorbs and retains a liquid discharged from a pet P inside. The liquid to be absorbed refers to a liquid substance discharged from the inside of the pet P, and typically, urine discharged from the pet P can be cited. Further, blood, semen can also be cited. Hereinafter, the absorbent article 1 will be described taking urine as an example of the liquid to be absorbed.

[0054] In the following description, an example in which the pet wearing the absorbent article 1 is a dog is shown, but other pets can also wear the absorbent article 1. For example, a cat can also wear the absorbent article 1.

[0055] The absorbent article 1 of the present embodiment has a belt-like shape, and has a length direction, a width direction, and a thickness direction orthogonal to each other. As shown in Figure 1 The absorbent article 1 is worn in such a manner that the length direction is along the waist direction of the pet P, and is wrapped around the waist H of the pet P in front of the thigh T of the pet P (on the head side).

[0056] In the present embodiment, "belt-like" is a description indicating a case where elongation is relatively long in one direction. In this sense, the "belt-like shape" is not limited to a mathematical rectangle, and the shape of the side can not be a straight line.

[0057] When the absorbent article 1 is worn in such a posture, the absorbent article 1 covers the urethral opening of the pet P, and can absorb and retain urine discharged from the pet P.

[0058] In the following description, the surface of the absorbent article 1 opposite to the pet P when worn will be referred to as "front surface", and the surface facing outward opposite to the pet P when worn will be referred to as "back surface".

[0059] Figure 2 is a schematic view showing a wearing state of the pet use absorbent article 1 of the present embodiment. The absorbent article 1 is suitable for use with a male pet. The absorbent article 1 absorbs and retains a liquid discharged from a pet P inside. The liquid to be absorbed refers to a liquid substance discharged from the inside of the pet P, and typically, urine discharged from the pet P can be cited. Further, blood, semen can also be cited. Hereinafter, the absorbent article 1 will be described taking urine as an example of the liquid to be absorbed.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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] (Main Body)

[0064] 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.

[0065] 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.

[0066] 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).

[0067] 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.

[0068] The surface sheet 11 allows liquid (pet P's urine) to pass through. The surface sheet 11 is made of, for example, nonwoven fabric.

[0069] 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.

[0070] The back layer 12 has a waterproof film 121 that does not allow the urine of the pet P to pass through, and a nonwoven fabric 122 provided at a position outside the waterproof film 121. Printing can also be performed on the back surface side face 121a of the waterproof film 121. Furthermore, printing can also be performed on the nonwoven fabric 122.

[0071] In Figure 3 In the absorbent article 1 illustrated, the length in the width direction of the surface sheet 11 coincides with the length in the width direction of the waterproof film 121. Furthermore, the length in the width direction of the nonwoven fabric 122 is longer than the length in the width direction of the surface sheet 11 and the length in the width direction of the waterproof film 121. The nonwoven fabric 122 completely covers the surface sheet 11 and the waterproof film 121 in the field of view when viewed from the back.

[0072] The absorbent body 13 is disposed between the surface sheet 11 and the back layer 12. The absorbent body 13 absorbs liquid (urine of the pet P). As Figure 2 illustrated, the absorbent body 13 extends in the length direction X of the absorbent article 1, and is disposed at the center in the length direction X of the absorbent article. The length in the width direction Y of the absorbent body 13 is shorter than the length in the length direction X of the absorbent body 13.

[0073] The absorbent body 13, which is the absorbent body of the absorbent article for pets, can employ a known structure. For example, the absorbent body 13 has a core that uses an absorbent raw material as a material, and a wrapping material that wraps the core, and is a member that is rectangular in plan view.

[0074] As the absorbent raw material, fluff pulp and a high-absorbency polymer can be cited. As the fluff pulp, for example, chemical pulp, cellulose fiber, rayon, acetate fiber, and the like can be cited. As the high-absorbency polymer, a granular or fibrous polymer of a starch-based, acrylic acid-based, or amino acid-based polymer can be cited.

[0075] As the wrapping material, a nonwoven fabric wrapping material and a cotton paper wrapping material can be cited.

[0076] (First leakage suppressing portion)

[0077] The first leakage suppressing portion 20 is provided on the surface sheet 11 side of the main body portion 10. The first leakage suppressing portion 20 is a belt-shaped member that extends in the length direction X of the main body portion 10.

[0078] The first leakage suppressing portion 20 has a first suppressing portion main body 200 that uses a hydrophobic nonwoven fabric as a material and extends in the length direction X, and an elastic member 201 that is installed along the length direction of the first suppressing portion main body 200. The nonwoven fabric that is the material of the first leakage suppressing portion 20 can be subjected to waterproof processing.

[0079] In addition, in the following description, an "end portion" refers to an area including a certain range that includes the edge of an article.

[0080] Furthermore, an "end" refers to the edge of an article. The same applies to "one end" and "the other end".

[0081] The first leakage suppression portion 20 has a first joint 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.

[0082] The first joint 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 joint 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.

[0083] The first standing portion 20Y is the end portion on the buttocks 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 buttocks side B of the first leakage suppression portion 20.

[0084] And, as Figure 4 shown, the first leakage suppression portion 20 may also be provided with a third joint portion 20Z joined to the surface sheet 11. In the present embodiment, the third joint portion 20Z is provided at the end portion on the buttocks side B in the width direction Y of the first leakage suppression portion 20 and at both end portions in the length direction X.

[0085] When the first leakage suppression portion 20 is joined to the surface sheet 11 at the third joint portion 20Z, the range of the first standing portion 20Y refers to the end portion on the buttocks side B 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.

[0086] In the first standing portion 20Y, the end portion on the inner side in the width direction Y of the first suppression portion main body 200 is folded back along the length direction X while being wound around the elastic member 201. As Figure 2 shown, the elastic member 201 is provided near the center in the length direction X of the main body portion 10 and is locally fixed in a state of being stretched along the length direction X during manufacturing. The elastic member 201 is released from the force applied to stretch the elastic member 201 during manufacturing and contracts along the length direction X based on the contraction force (elastic force) of the elastic member 201.

[0087] The material of the elastic member 201 is simply an elongated and stretchable material. Specifically, the material of the elastic member 201 can use a thread-like rubber formed of natural rubber, flat rubber, or the like, a thermoplastic elastomer such as polyurethane, ethylene-vinyl acetate copolymer (EVA), PE, or the like. As the thermoplastic elastomer, an elastomer formed into a thread-like shape or a film shape and cut into a relatively thin width can be exemplified, including polybutadiene, polyisoprene, styrene-butadiene copolymer, styrene-isoprene copolymer, polyurethane, ethylene-vinyl acetate copolymer, ethylene-a-olefin copolymer, or the like.

[0088] The end portion of the inner side of the first suppression portion main body 200 and the region of the tape shape which is folded back are joined to the opposite first suppression portion main body 200. In the first standing portion 20Y, the portion in which the first suppression portion main body 200 is wrapped in the elastic member 201 and joined constitutes a gather portion 25. The gather portion 25 is a structure known as a three-dimensional gather.

[0089] The region in which the gather portion 25 is formed is contracted along with the contraction of the elastic member 201. Therefore, the first standing portion 20Y is contracted in the length direction X of the first standing portion 20Y.

[0090] Further, the first leakage suppression portion 20 is joined to the nonwoven fabric 122 of the main portion 10 at the end portion of the head side A in the width direction Y of the first leakage suppression portion 20 in a state in which the elastic member 181 is interposed between the nonwoven fabric 122 of the main portion 10. The elastic member 181 is provided along the length direction X of the main portion 10 so as to be fixed in a state in which it is elongated in the length direction X. In the first leakage suppression portion 20, the portion joined to the nonwoven fabric 122 of the main portion 10 with the elastic member 181 interposed therebetween constitutes a first wing portion 18. The first wing portion 18 is located at the outermost side of the head side A in the width direction Y of the main portion 10 and extends in the length direction X.

[0091] The material of the elastic member 181 can use the same material as the material of the elastic member 201.

[0092] (Second Leakage Suppression Portion)

[0093] The second leakage suppression portion 30 is provided on the surface sheet 11 side of the main portion 10. The second leakage suppression portion 30 is a tape-shaped member extending in the length direction X of the main portion 10. Further, the width of the second leakage suppression portion 30 is narrower than the width of the first leakage suppression portion 20.

[0094] The second leakage suppression portion 30 has a second suppression portion main body 300 which uses a hydrophobic nonwoven fabric as a material and extends in the length direction X. The nonwoven fabric used as the material of the second leakage suppression portion 30 can be subjected to waterproof processing.

[0095] The second leakage suppressing portion 30 has a second joint portion 30X as a region that is joined to the main body portion 10 and a second standing portion 30Y as a region that is not joined to the main body portion 10.

[0096] The second joint portion 30X is an end portion of the buttocks side B in the width direction Y of the second leakage suppressing portion 30 and is a region that is joined to the main body portion 10 (the surface sheet 11 and the back sheet 12). The second joint portion 30X is provided at the end portion of the buttocks side B of the second leakage suppressing portion 30 along the length direction X. The method of joining can be either fusion or adhesion.

[0097] The second standing portion 30Y is an end portion of the head side A in the width direction Y of the second leakage suppressing portion 30 and is a region that is not joined to the main body portion 10. The second standing portion 30Y is provided at the end portion of the head side A of the second leakage suppressing portion 30 along the length direction X.

[0098] The second standing portion 30Y is different from the first standing portion 20Y in that it does not have an elastic member that contracts the second standing portion 30Y in the length direction.

[0099] Both end portions in the length direction X of the second standing portion 30Y can also be weakly joined to the surface sheet 11. In Figure 2 In the embodiment, the portion that is weakly joined is indicated by reference numeral HM.

[0100] Weak joining indicates joining that is performed with a strength that maintains the joined state in the case where a weak force is applied to the joined portion (for example, the case where a force to the extent of unfolding the folded pet absorbent article 1 is indirectly transmitted to the joined portion) but releases the joined state in the case where a force of a predetermined level or greater is applied to the joined portion (for example, the case where a force in the direction that releases the joining is applied to the joined portion due to movement of the body of the pet that is in abutment with the pet wearing the article).

[0101] Further, the second leakage suppressing portion 30 is joined to the nonwoven fabric 122 of the main body portion 10 at the end portion of the buttocks side B in the width direction Y of the second leakage suppressing portion 30 with the elastic member 191 interposed therebetween. The elastic member 191 is provided along the length direction X of the main body portion 10 and is fixed in a state of being elongated in the length direction X. In the second leakage suppressing portion 30, the portion that is joined to the nonwoven fabric 122 of the main body portion 10 with the elastic member 191 interposed therebetween constitutes a second wing portion 19. The second wing portion 19 is located at the outermost side in the width direction Y of the main body portion 10 (the surface sheet 11 and the back sheet 12) and extends in the length direction X.

[0102] The material of the elastic member 191 can be the same material as the material of the elastic member 201 described above.

[0103] As described above, the first standing portion 20Y has the elastic member 201 that contracts in the length direction, whereas the second standing portion 30Y does not have the elastic member and does not contract in the length direction. That is, the contraction force in the length direction X of the second standing portion 30Y is smaller than the contraction force in the length direction X of the first standing portion 20Y.

[0104] The test pieces were cut out from the first standing portion 20Y and the second standing portion 30Y in the length direction X, and the contraction forces of the first standing portion 20Y and the second standing portion 30Y were measured by measuring the tensile load.

[0105] The test pieces were produced as follows.

[0106] First, the absorbent article 1 was stretched in the length direction X to the extent that no wrinkles (pleats) were generated on the surface of the first standing portion 20Y due to the contraction of the elastic member 181. Next, the test pieces were cut out from the first standing portion 20Y and the second standing portion 30Y of the stretched absorbent article 1.

[0107] When the test pieces were cut out from the first standing portion 20Y, the test pieces were produced in such a manner that the pleat portion 25 was included in the entire region in the length direction of the test pieces. That is, when the region in which the pleat portion 25 was not included was included in the length direction X of the first standing portion 20Y, the test pieces were cut out in such a manner that the above-described "region in which the pleat portion 25 was not included" was not included.

[0108] The size of the test pieces in the state in which the test pieces were cut out, that is, the state in which the absorbent article 1 was stretched in the length direction X to the extent that no wrinkles (pleats) were generated, was used as the initial size of the test pieces.

[0109] The tensile load (N) was measured with respect to the produced test pieces using an Autograph-type tensile testing machine (manufactured by Shimadzu Corporation, model AG-1KN1).

[0110] The tensile load at the time when the size in the length direction of the test pieces became 75% of the initial size was measured in a state in which one end portion in the length direction of each test piece was clamped to a fixed chuck and the other end portion in the length direction was clamped to a movable chuck, and the movable chuck was moved at a speed of 300 mm / min.

[0111] The genitals of the pet P wearing the absorbent article 1 were in a position overlapping the second standing portion 30Y. The second standing portion 30Y was in contact with the pet P along the torso and the genitals while forming wrinkles.

[0112] Here, the 2nd rise portion 30Y is formed with less wrinkles than the 1st rise portion 20Y which contracts in the longitudinal direction, because the 2nd rise portion 30Y does not have an elastic member and does not contract in the longitudinal direction. Further, in the 2nd rise portion 30Y which does not have an elastic member, even if wrinkles are generated, the position where the wrinkles are formed is easily changed, and the position where the edges of the wrinkles contact the genital organ is easily changed.

[0113] Therefore, even if the genital organ of the pet P is in a position overlapping the 2nd rise portion 30Y, the frictional irritation of the genital organ against the 2nd rise portion 30Y is easily dispersed, and inflammation of the skin is not easily generated.

[0114] Further, the absorbent article 1 is able to suppress urine leakage because of the presence of the 1st rise portion 20Y and the 2nd rise portion 30Y.

[0115] Therefore, the absorbent article 1 is able to suppress urine leakage while suppressing friction against the genital organ at the time of wearing.

[0116] As shown in Figure 4 , the detailed configuration of each structure of the absorbent article 1 is described below. In the absorbent article 1, the central axis in the width direction Y is set as CL1, and the central axis in the longitudinal direction X is set as CL2. The central portion in the longitudinal direction X of the absorbent article 1 refers to the vicinity of the central axis CL2.

[0117] First, most of the structures of the absorbent article 1 are configured to be linearly symmetrical with respect to the central axis CL1 in the width direction Y. The distance A3 from the central axis CL1 to the 1st joint portion 20X is equal to the distance B3 from the central axis CL1 to the 2nd joint portion 30X. Further, the distance A4 from the 1st joint portion 20X to the end 10x of the head side A in the width direction Y of the main body portion 10 is equal to the distance B4 from the 2nd joint portion 30X to the end 10y of the buttocks side B in the width direction Y of the main body portion 10.

[0118] In addition, as shown in Figure 4 , when measuring the distance between the 1st joint portion 20X, the end 20a of the 1st joint portion 20X is used as a reference. The end 20a is an interface between a region (1st joint portion 20X) joined to the main body portion 10 and a region (1st rise portion 20Y) not joined to the main body portion 10 in the width direction of the 1st leakage suppression portion 20.

[0119] Further, when measuring the distance between the 2nd joint portion 30X, the end 30a of the 2nd joint portion 30X is used as a reference. The end 30a is an interface between a region (2nd joint portion 30X) joined to the main body portion 10 and a region (2nd rise portion 30Y) not joined to the main body portion 10 in the width direction of the 2nd leakage suppression portion 30.

[0120] Further, the absorbent body 13 is configured to be linearly symmetrical with respect to the central axis CL1 in the width direction Y of the main body portion 10. That is, the distances from both ends in the width direction of the absorbent body 13 to the central axis CL1 are equal to each other (A5=B5). Further, the distances from both ends in the length direction of the absorbent body 13 to the central axis CL2 are also equal to each other (C1=D1).

[0121] However, the first erected portion 20Y and the second erected portion 30Y are not linearly symmetrical with respect to the central axis CL1. In detail, in the central portion in the length direction X of the main body portion 10, the sum of the distance Al from the head-side end in the width direction Y of the absorbent body 13 to the first joint portion 20X and the distance A2 from the first joint portion 20X to the inner side end 20b of the first erected portion 20Y is larger than the sum of the distance Bl from the hip-side end in the width direction Y of the absorbent body 13 to the second joint portion 30X and the distance B2 from the second joint portion 30X to the inner side end 30b of the second erected portion 30Y. That is, the relation (Al+A2)>(Bl+B2) holds.

[0122] In the absorbent article 1, in the central portion in the length direction X of the main body portion 10, the distance Al is equal to the distance Bl, and the distance A2 is longer than the distance B2 (A2>B2).

[0123] Further, in the absorbent article 1, the distance Al is shorter than the distance A2, and the inner side end 20b of the first erected portion 20Y overlaps the absorbent body 13 when viewed from above (A2>Al). Further, in the absorbent article 1, the distance Bl is longer than the distance B2, and the inner side end 30b of the second erected portion 30Y does not overlap the absorbent body 13 when viewed from above (Bl>B2).

[0124] At this time, in the central portion in the length direction X of the main body portion 10, the distance Al can also be longer than the distance Bl (Al>Bl). That is, the absorbent body 13 can also be configured to be offset toward the hip side B of the main body portion 10.

[0125] Further, in the absorbent article 1, in the width direction Y of the main body portion 10, the distance A6 from the outer side end of the third joint portion 20Z to the inner side end of the first erected portion 20Y can also be shorter than the distance B2 (B2>A6). The third joint portion 20Z can also be continuous with the first joint portion 20X. In this case, the distance A6 is 0.

[0126] If the distance A6 is made shorter than the distance B2, when the absorbent article 1 is stacked to be small at the time of disposal of the absorbent article 1, urine is less likely to leak from the gap between the third joint portion 20Z and the first erected portion 20Y.

[0127] Figure 5is an explanatory view that explains other effects of the absorbent article 1, and is a schematic cross-sectional view at the center axis CL2 when the pet P wears the absorbent article 1. The urethral orifice UM of the pet P wearing the absorbent article 1 is, for example, in a position overlapping the absorbent body 13. The pet P discharges urine toward the head side A.

[0128] At this time, a space surrounded by the first standing portion 20Y and the main body portion 10 is formed in the direction of urination, and blocks 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 absorbent body 13 in the process of returning to the rear (buttocks side B), and thus is effectively absorbed by the absorbent body 13. Even if a small amount of urine U not absorbed by the absorbent body 13 passes over the absorbent body 13, it is blocked by the second standing portion 30Y.

[0129] Here, by the above-described relationship (A1+A2)>(B1+B2) being satisfied, a relatively large space compared to the buttocks side B is formed at a position closer to the head side A than the absorbent body 13, and it is possible to receive and block the discharged urine U in a large range. Further, it is possible to hold the urine U using the space surrounded by the first standing portion 20Y and the main body portion 10 in a short time before the urine U is absorbed by the absorbent body 13. Therefore, even if the urine U is discharged abruptly, it is possible to suppress the urine leakage from the head side A. Further, it is possible to effectively guide the urine U to the absorbent body 13 to be absorbed.

[0130] (Fastening portion)

[0131] Figure 6 is a rear view of the absorbent article 1. As shown in Figure 6 , the absorbent article 1 has a fastening portion 40 at one end side in the length direction of the main body portion 10. The fastening portion 40 is a mechanical fastener. The fastening portion 40 connects the surface sheet 11 and the back sheet 12 at both ends in the length direction X of the main body portion 10, and fixes the absorbent article 1 to be a tubular shape. By this, the absorbent article 1 is fixed to the waist of the pet P.

[0132] In the present embodiment, the fastening portion 40 is provided along the width direction of the back sheet 12. Therefore, the absorbent article 1 is fixed to be a tubular shape by connecting the fastening portion 40 to the surface sheet 11 with the front surface of the other end side in the length direction X of the main body portion 10 overlapping the back surface of the one end side in the length direction X. If the fastening portion 40 is thus provided to the back sheet 12, the fastening portion 40 is exposed to the outside when the absorbent article 1 is worn on the pet P, and therefore the fastening portion 40 is easily recognized by the operator, and the wearing on the pet P becomes easy.

[0133] The fastening portion 40 can also be provided to the surface sheet 11. In this case, the absorbent article 1 is fixed to be a tubular shape by connecting the fastening portion 40 to the back sheet 12 with the back surface of the other end side in the length direction X of the main body portion 10 overlapping the front surface of the one end side in the length direction X.

[0134] In the absorbent article 1, the center axis CL3 of the width direction Y of the locking portion 40 is positioned at a position closer to the second joint portion 30X than the center position (center axis CL1) between the first joint portion 20X and the second joint portion 30X. That is, in the absorbent article 1, the locking portion 40 is relatively shifted toward the buttocks side B. Thus, the absorbent article 1 is fixed on the side closer to the buttocks, and the side on which the second standing portion 30Y (refer to Figure 4 ) is disposed is relatively tightly pinched, so that leakage of urine from the back can be suppressed.

[0135] The region in which the locking portion 40 is provided can be formed uniformly, but can also be such that the structure in the thickness direction (z direction) differs depending on the region. In the absorbent article 1 of such a structure, the rigidity of the region in which the locking portion 40 is provided differs depending on the site, and there is a high-rigidity region in which the rigidity is relatively high.

[0136] For example, in the case where the locking portion 40 is provided shifted toward the head side A, a part of the head side A of the locking portion 40 overlaps the first leakage suppressing portion 20 planarly, and the remaining part does not overlap the first leakage suppressing portion 20. Likewise, in the case where the locking portion 40 is provided shifted toward the buttocks side B, a part of the buttocks side B of the locking portion 40 overlaps the second leakage suppressing portion 30 planarly, and the remaining part does not overlap the second leakage suppressing portion 30 planarly. According to such a difference in the structure in the thickness direction, a difference in rigidity is generated in the region in which the locking portion 40 is provided.

[0137] In the above example, the region in which the locking portion 40 overlaps the first leakage suppressing portion 20 or the second leakage suppressing portion 30 has a relatively high rigidity compared to the other region in which it does not overlap. Such a region of higher rigidity corresponds to the "high-rigidity region" in the present application.

[0138] In the case where the pet P moves while wearing the absorbent article 1, force is applied to the absorbent article 1 from multiple directions, and it is sometimes pulled and dislocated or the end portion is rolled up. If the locking portion 40 has a high-rigidity region, the high-rigidity region is less likely to be deformed compared to the region of relatively low rigidity (low-rigidity region), and dislocation of the absorbent article 1, rolling up of the end portion of the periphery of the high-rigidity region can be suppressed.

[0139] Also, the high-rigidity region can be formed by changing the structure of the locking portion 40 itself. That is, the locking portion can not be formed uniformly, but can have portions of relatively different rigidity.

[0140] Figures 7 to 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] (Color-changing section)

[0146] 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.

[0147] 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 raised 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.

[0148] (Marking section)

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] (How to fold absorbent items)

[0155] Figures 10 to 13is an enlarged sectional view showing the outline configuration of the periphery of the 2nd standing portion 30Y. The absorbent article 1 is folded in the posture of rolling the front face 10a to the inner side in the longitudinal direction and the lateral direction at the time of storage, at the time of sale. At this time, in the periphery of the 2nd standing portion 30Y, according to the folding method, the following effects are obtained.

[0156] Figure 10 , Figure 12 is an enlarged sectional view showing the case where the absorbent article 1 is folded. First, in the case where the absorbent article 1 is folded in the posture of rolling the 2nd standing portion 30Y to the inner side as shown in Figure 10 , Figure 12 common to both of them, the surface sheet 11 and the back sheet 12 are folded back in the posture of rolling the 2nd standing portion 30Y to the inner side in such a manner that the 2nd wing portion 19 faces the front face 10a. As a result, in the absorbent article 1, a fold line L is provided in the lengthwise direction X of the surface sheet 11 and the back sheet 12. The 2nd wing portion 19 corresponds to the "wing portion" in the present application.

[0157] As one method, consider folding the absorbent article 1 in the posture of overlapping the fold line L with the 2nd standing portion 30Y as shown in Figure 10 In this case, the 2nd standing portion 30Y has a habitual fold formed by the fold line L.

[0158] If the absorbent article 1 thus folded is unfolded at the time of use, as shown in Figure 11 the end 30b of the 2nd standing portion 30Y on the inner side is liable to be raised due to the habitual fold. Therefore, for the absorbent article 1 folded as shown in Figure 10 , it is expected that the 2nd standing portion 30Y is liable to intercept urine and thus is liable to suppress urine leakage.

[0159] As another method, consider folding the absorbent article 1 in the posture of not overlapping the fold line L with the 2nd standing portion 30Y but in a position on the inner peripheral side of the 2nd standing portion 30Y from the main body portion 10 as shown in Figure 12 In this case, the 2nd standing portion 30Y does not have a habitual fold formed by the fold line L.

[0160] If the absorbent article 1 thus folded is unfolded at the time of use, as shown in Figure 13 the end 30b of the 2nd standing portion 30Y is relatively less liable to be raised than in the state shown in Figure 8 Therefore, for the absorbent article 1 folded as shown in Figure 9 , the 2nd standing portion 30Y is less liable to come into contact with the genital organ of the pet P, and even if it comes into contact, the 2nd standing portion 30Y is weak in the force of pressing against the genital organ. Therefore, for the absorbent article 1 folded as shown in Figure 9 , it is expected that the friction with the genital organ at the time of wearing is liable to be suppressed.

[0161] The absorbent article 1 having the above structure can suppress friction with the genital organ when worn.

[0162] (Modified Example)

[0163] Figure 14 is a schematic view showing a modified example of the present embodiment, and is a schematic plan view showing a central portion in the length direction of the absorbent article when viewed from above.

[0164] Figure 14 The absorbent article 2 shown has an absorbent body 15. The absorbent body 15 protrudes in the direction of the second leakage suppressing portion 30 in the central portion in the length direction X of the main body portion 10. That is, the absorbent body 15 has a first portion 151 that is rectangular when viewed from above, and a second portion 152 that protrudes in the direction of the second leakage suppressing portion 30.

[0165] In the absorbent article 2, the end 30b on the inner side of the second standing portion 30Y overlaps the second portion 152 of the absorbent body 15 when viewed from above.

[0166] As described above, if 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 during the process of returning to the rear (the buttocks side B). Here, if the amount of the excreted urine U is large or is excreted abruptly, the urine U that is not completely absorbed by the absorbent body 13 can pass over the absorbent body 13 in a large amount.

[0167] In such a case, also if 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, and the urine U is easily absorbed, and the leakage of the urine from the buttocks side B is easily suppressed.

[0168] [Second Embodiment]

[0169] Figure 15 is an explanatory view of the absorbent article 3 of the second embodiment of the present invention, and is a cross-sectional view in the field of view corresponding to the Figure 3 of the first embodiment. In the present embodiment, the same reference numerals are attached to the constituent elements common to the first embodiment, and detailed description is omitted.

[0170] In the absorbent article 1 of the first embodiment, the first standing portion 20Y is contracted in the length direction, and the second standing portion 30Y is not contracted in the length direction, but in the absorbent article 3 of the present embodiment, the first standing portion and the second standing portion are contracted in the length direction. That is, in the present invention, it is also possible that the first standing portion is contracted in the length direction of the first standing portion, and the second standing portion is contracted in the length direction of the second standing portion.

[0171] As Figure 15The absorbent article 3 of the present embodiment has a main body portion 10, a first leakage suppressing portion 21, and a second leakage suppressing portion 31.

[0172] The first leakage suppressing portion 21 of the absorbent article 3 has a first suppressing portion main body 200 of a hydrophobic nonwoven fabric in a belt shape as a material and a first elastic member 201 installed along the length direction of the first suppressing portion main body 200. The gather portion 25 of the first leakage suppressing portion 21 has two first elastic members 201.

[0173] The first leakage suppressing portion 21 has a first joint portion 21X as a region that is joined to the main body portion 10 and a first standing portion 21Y as a region that is not joined to the main body portion 10.

[0174] The first joint portion 21X refers to the same region as the first joint portion 20X of the absorbent article 1 of the first embodiment. The first standing portion 21Y refers to the same region as the first standing portion 20Y of the absorbent article 1 of the first embodiment.

[0175] The second leakage suppressing portion 31 has a second suppressing portion main body 300 of a hydrophobic nonwoven fabric in a belt shape as a material and a second elastic member 301 installed along the length direction of the second suppressing portion main body. The absorbent article 3 has one second elastic member 301. That is, the number of second elastic members 301 is less than the number of first elastic members 201.

[0176] The second leakage suppressing portion 31 has a second joint portion 31X as a region that is joined to the main body portion 10 and a second standing portion 31Y as a region that is not joined to the main body portion 10.

[0177] The second leakage suppressing portion 31 has a second joint portion 31X as a region that is joined to the main body portion 10 and a second standing portion 31Y as a region that is not joined to the main body portion 10.

[0178] The first joint portion 21X refers to the same region as the second joint portion 30X of the absorbent article 1 of the first embodiment. The second standing portion 31Y refers to the same region as the second standing portion 30Y of the absorbent article 1 of the first embodiment.

[0179] In the second standing portion 30Y, the end portion of the head side A in the width direction Y of the second suppressing portion main body 300 is rolled into the second elastic member 301 and folded back along the length direction X. The second elastic member 301 is provided, for example, near the center of the length direction X of the second standing portion 31Y opposite to the first elastic member 201 of the first standing portion 21Y and is partially fixed in a state of being elongated in the length direction X at the time of manufacture. The second elastic member 301 releases the force applied at the time of manufacture to elongate the second elastic member 301 and contracts in the length direction X.

[0180] The end portion of the inner side of the 2nd suppression portion main body 300 and the region of the belt shape which is folded back are engaged with the opposite 2nd suppression portion main body 300. The portion of the 2nd standing portion 31Y in which the 2nd suppression portion main body 300 is wrapped with the 2nd elastic member 301 and engaged constitutes a gather portion 35. The gather portion 35 is a structure known as a three-dimensional gather.

[0181] The region in which the gather portion 35 is formed shrinks with the contraction of the 2nd elastic member 301. Therefore, the 2nd leakage suppression portion 31 shrinks in the length direction X of the 2nd leakage suppression portion 31.

[0182] The material of the 2nd elastic member 301 can use the same material as the material of the above-mentioned elastic member 201.

[0183] In the absorbent article 3 of such a structure, the 2nd elastic member 301 possessed by the 2nd standing portion 31Y is less than the 1st elastic member 201 possessed by the 1st standing portion 21Y. That is, in the absorbent article 3, the shrinkage force in the length direction of the 2nd standing portion 31Y is less than the shrinkage force in the length direction of the 1st standing portion 21Y.

[0184] The shrinkage force of the 1st standing portion 21Y which is the basis for the relative comparison of the shrinkage force can be set to be equal to the shrinkage force of the three-dimensional gather which is generally adopted in the conventional absorbent article. That is, the shrinkage force of the 2nd standing portion 31Y is weaker than the shrinkage force of the three-dimensional gather which is generally adopted in the conventional absorbent article.

[0185] In the absorbent article 3 of such a structure, the 2nd standing portion 31Y is formed with relatively fewer wrinkles than the 1st standing portion 21Y. Or, in the 2nd standing portion 31Y, even if wrinkles are generated, the wrinkles are easily deformed, and the 2nd standing portion 31Y is easily elongated until there are no wrinkles.

[0186] Therefore, even if the genital organ of the pet P is in a position overlapping the 2nd standing portion 31Y, the frictional irritation of the genital organ from the 2nd standing portion 31Y is easily dispersed, and inflammation of the skin is not easily generated.

[0187] Further, in the absorbent article 3, the shrinkage forces of the 1st standing portion 21Y and the 2nd standing portion 31Y are controlled by the difference in the number of elastic members. Therefore, it is easy to control the shrinkage force in the length direction of the 2nd standing portion 31Y to be less than the shrinkage force in the length direction of the 1st standing portion 21Y.

[0188] Even the absorbent article 3 of the above structure can suppress the friction with the genital organ at the time of wearing.

[0189] In addition, the method of controlling the shrinkage force of the 2nd standing portion 31Y can employ the following method in addition to the above-mentioned number of elastic members. Figure 16 、 Figure 17is a plan view showing a modification of the second standing portion of the second leakage suppressing portion.

[0190] First, as shown in Figure 16 the second elastic member 301 at the end 32b inside the second standing portion 32Y. If the number of slits S is increased to increase the cut portions of the second elastic member 301, there is a tendency for the contraction force to decrease.

[0191] Further, as shown in Figure 17 the second elastic member 301 possessed by the second standing portion 33Y is routed so as to protrude outward (hip side) at the central portion in the length direction of the second standing portion 33Y. The portion where the second elastic member 301 protrudes outward is indicated by reference numeral 331.

[0192] The distance from the end 32b of the second standing portion 33Y to the second elastic member 301 is longer than in the case where the second elastic member 301 is not routed in a convex shape but is provided linearly in the length direction. Therefore, in the case where the second standing portion 33Y comes into contact with the genitals of the pet P, the contact area of the nonwoven fabric with the genitals increases relatively more than in the case of the second standing portion where the second elastic member 301 is provided linearly in the length direction. Therefore, the force imparted to the genitals by the second standing portion 33Y is easily dispersed, and the genitals are less likely to be pricked.

[0193] In order to obtain the same effect as that of the above-described second standing portion 33Y, the position of the second elastic member 301 can also be changed. Specifically, the position of the second elastic member 301 can also be moved outward (hip side) in the width direction Y in the second standing portion.

[0194] Further, in order to change the contraction force of the first elastic member 201 and the second elastic member 301, at least one of the material, the thickness, and the weaving method of the first elastic member 201 and the second elastic member 301 can also be changed.

[0195] Further, the type of nonwoven fabric as the material of the first suppressing portion main body 200 and the second suppressing portion main body 300 can also be changed.

[0196] Further, as a method of controlling the contraction force of the first standing portion and the second standing portion, the elongation method of the first elastic member 201 and the second elastic member 301 can also be changed at the time of manufacture. Even if the same elastic member is used, if it is fixed in a state of being elongated more at the time of manufacture, there is a tendency for the contraction force to increase.

[0197] Figure 18 is a plan view showing a modification of the second leakage suppressing portion. Figure 18The illustrated second leakage suppressing portion 34 has a narrow portion 341 in which the width narrows in the central portion in the length direction of the second standing portion 34Y. The narrow portion 341 is a recessed portion provided in the inner side end 34b in the central portion in the length direction.

[0198] In the case where the absorbent article having the second leakage suppressing portion 34 is worn by the pet P, the genitals of the pet P overlap the narrow portion 341. Therefore, the second standing portion 34Y is less likely to come into contact with the genitals of the pet P, and even if it comes into contact, the second standing portion 34Y exerts a weak pressing force on the genitals. Therefore, for the absorbent article having the second leakage suppressing portion 34, an effect of easily suppressing friction with the genitals at the time of wearing can be expected.

[0199] The above describes a preferred embodiment of the present application with reference to the drawings, but the present application is not limited to this example. The shapes, combinations, and the like of each of the constituent members illustrated in the above example are one example, and various changes can be made based on design requirements and the like without departing from the spirit of the present application.
