Summary of the Invention

Problems to be Solved by the Invention

[0004] In order to prevent urine leakage, it is important to improve the fit of the absorbent article for pets. However, in the above-described absorbent article for pets, there is a risk of a gap being formed between the body of the pet and the absorbent article for pets due to changes in the posture of the pet, changes in body shape before and after meals, and respiratory movements. In addition, when the pet urinates and the urine is absorbed by the absorbent body, the absorbent body becomes heavy and sags, and a gap may be formed between the body of the pet and the absorbent article for pets. When such a gap is formed, there is a risk of urine leakage.

[0005] Therefore, an object of the present disclosure is to improve the fit of the absorbent article for pets.

Means for Solving the Problems

[0006] In one aspect, there is provided an absorbent article for pets that is wrapped around the torso of a pet for attachment. This absorbent article for pets is an absorbent article for pets that is wrapped around the torso of a pet for attachment, and has a main body portion having a horizontally long shape with a longitudinal direction and a lateral direction, a first portion disposed on one side in the longitudinal direction with respect to the center line of the main body portion in the longitudinal direction, and a second portion disposed on the other side in the longitudinal direction with respect to the center line of the main body portion in the longitudinal direction. The main body portion includes a surface sheet disposed on the skin side, a back sheet disposed on the non-skin side, an absorber disposed between the surface sheet and the back sheet, and one or more elastic members that can expand and contract in the longitudinal direction or the lateral direction. The elastic member overlaps the absorber when viewed from the thickness direction of the main body portion.

[0009] [Summary of Embodiments of the Present Disclosure] The summary of the embodiments of the present disclosure will be described with reference to the clauses listed below. Note that the present disclosure includes any combination of the following clauses.

[0010] (Clause 1) An absorbent article for pets according to one aspect is worn by being wound around the pet's torso. This absorbent article for pets has a main body portion having a horizontally long shape with a longitudinal direction and a lateral direction, a first portion disposed on one side in the longitudinal direction with respect to the center line of the main body portion in the longitudinal direction, and a second portion disposed on the other side in the longitudinal direction with respect to the center line of the main body portion in the longitudinal direction. The main body portion includes a surface sheet disposed on the skin side, a back sheet disposed on the non-skin side, an absorber disposed between the surface sheet and the back sheet, and one or more elastic members that can expand and contract in the longitudinal direction or the lateral direction. The elastic member overlaps the absorber when viewed from the thickness direction of the main body portion.

[0011] In the absorbent article for pets according to the above aspect, since one or more elastic members arranged to overlap the absorber contract so as to follow changes in the pet's body posture and body shape, the fit of the absorbent article for pets is improved. Also, even when urine is absorbed by the absorber, the absorber is lifted by the contraction force of the elastic member, suppressing the sagging of the absorber and maintaining the fit of the absorbent article for pets. Therefore, according to this absorbent article for pets, urine leakage can be suppressed.

[0012] (Clause 2) The absorbent article for pets according to item 1 may further include a pair of leak-proof gathers that are spaced apart from each other in the short direction and can stand up with respect to the surface sheet. By providing the pair of leak-proof gathers, it is possible to suppress the leakage of urine excreted by the pet onto the absorber in the short direction.

[0013] (Item 3) In the absorbent article for pets according to item 1 or 2, the one or more elastic members may be stretchable in the longitudinal direction. In this case, since the one or more elastic members contract in the longitudinal direction so as to follow changes in the body shape and posture of the pet (for example, an action in which the pet twists its body), the fit of the absorbent article for pets can be improved.

[0014] (Item 4) In the absorbent article for pets according to item 1 or 2, the one or more elastic members may be stretchable in the short direction. In this case, since the one or more elastic members contract in the short direction so as to follow changes in the body shape and posture (for example, an action in which the pet stretches its body), the fit of the absorbent article for pets can be effectively improved.

[0015] (Item 5) In the absorbent article for pets according to any one of items 1 to 3, the one or more elastic members may extend in the longitudinal direction so as to straddle the absorber. In this case, since the absorber is lifted by the contraction force of the one or more elastic members, the sagging of the absorber when urine is absorbed is suppressed. Therefore, the generation of a gap between the body of the pet and the absorbent article for pets is suppressed, and as a result, urine leakage can be effectively suppressed.

[0016] (Item 6) In the absorbent article for pets according to any one of Items 1 to 3, one or a plurality of elastic members may extend from the inside to the outside of the absorber in the longitudinal direction. In this case, since the absorber is lifted from the outside of the absorber in the longitudinal direction, the sagging of the absorber is suppressed. Therefore, the fitness of the absorbent article for pets can be more reliably maintained.

[0017] (Item 7) In the absorbent article for pets according to any one of Items 1 to 6, the engaging portion may be provided on the outer surface of the back sheet and may be engageable with the front sheet. In this case, the absorbent article for pets can be easily attached to the pet using the engaging portion.

[0018] (Item 8) In the absorbent article for pets according to any one of Items 1 to 7, the first portion includes a non-stretchable region that does not include one or a plurality of elastic members, the second portion includes a stretchable region that includes one or a plurality of elastic members, and the shrinkage rate of the second portion may be higher than the shrinkage rate of the first portion. In this case, the first portion having a relatively low shrinkage rate can be applied to the body of the pet to align the absorbent article for pets. Further, when the second portion is engaged with the first portion, the relatively high shrinkage rate of the second portion causes the second portion to shrink, thereby reducing the looseness during wearing of the absorbent article for pets. Therefore, the absorbent article for pets can be appropriately attached to the pet.

[0019] (Item 9) In the absorbent article for pets according to any one of Items 1 to 6, the engaging portion may be provided on the front surface of the front sheet and may be engageable with the back sheet. In this case, the absorbent article for pets can be easily attached to the pet using the engaging portion.

[0020] (Item 10) In the absorbent article for pets according to Item 9, the first part includes an elastic region containing one or more elastic members, the second part includes a non-elastic region not containing one or more elastic members, and the shrinkage rate of the first part may be higher than the shrinkage rate of the second part. In this case, the absorbent article for pets can be aligned by applying the second part with a relatively low shrinkage rate to the body of the pet. Further, when engaging the first part with the second part, the relatively high shrinkage rate of the first part shrinks, thereby reducing looseness during wearing of the absorbent article for pets. Therefore, the absorbent article for pets can be properly worn on the pet.

[0021] (Item 11) In the absorbent article for pets according to any one of Items 1 to 10, one or more elastic members may overlap the engaging portion when viewed in the thickness direction. In this case, the engaging portion is pulled by the shrinking force of the elastic member, so that the first part and the second part are firmly engaged. Thereby, it is possible to prevent the absorbent article for pets from coming off unintentionally.

[0022] (Item 12) In the absorbent article for pets according to any one of Items 1 to 10, one or more elastic members may not overlap the engaging portion when viewed in the thickness direction. By arranging one or more elastic members so as not to overlap the engaging portion, it is possible to prevent the engaging portion from being deformed in a wavy manner by the shrinking force of the elastic member. Therefore, it is possible to prevent the engagement between the first part and the second part from being unintentionally released.

[0023] (Item 13) In the absorbent article for pets according to any one of Items 1 to 12, one or more elastic members may be arranged on the non-skin side with respect to the surface sheet. In this case, it is possible to prevent the elastic member from directly contacting the body of the pet when the absorbent article for pets is worn, so that the wearing feeling of the absorbent article for pets can be improved.

[0024] (Item 14) In the absorbent article for pets according to any one of Items 1 to 13, one or more elastic members may be rubber threads. In this case, the main body portion can be given elasticity.

[0025] (Item 15) In the absorbent article for pets according to any one of Items 1 to 13, one or more elastic members may be stretchable sheets. In this case, the wearing feeling of the absorbent article for pets can be improved.

[0026] (Item 16) In the absorbent article for pets according to any one of Items 1 to 15, the main body portion includes a plurality of elastic members that are stretchable in the longitudinal direction, and the plurality of elastic members may be arranged along the short side direction and extend over the entire area of the main body portion in the longitudinal direction. In this case, since the main body portion can be expanded and contracted over the entire longitudinal direction so as to follow changes in the body shape and posture of the pet, the fit of the absorbent article for pets can be improved. Therefore, urine leakage can be effectively suppressed.

[0027] (Item 17) In the absorbent article for pets according to Item 16, the plurality of elastic members may be arranged at equal intervals along the short side direction between a pair of side edges of the main body portion in the short side direction. In this case, the uniformity of the expansion and contraction force of the main body portion in the short side direction can be enhanced.

[0028] [Examples of Embodiments of the Present Disclosure] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the description of the drawings, the same reference numerals are assigned to the same elements, and redundant descriptions are omitted. The drawings may be drawn with some parts simplified or exaggerated for ease of understanding, and the dimensional ratios are not limited to those described in the drawings.

[0029] Hereinafter, an absorbent article for pets according to an embodiment will be described. FIG. 1 is a perspective view schematically showing an absorbent article 1 for pets according to an embodiment. FIG. 2 is a plan view of the absorbent article 1 for pets as viewed from the skin side Z1. FIG. 3 is a cross-sectional view of the absorbent article 1 for pets taken along line A-A in FIG. 1. FIG. 4 is a cross-sectional view of the absorbent article 1 for pets taken along line B-B in FIG. 1. FIG. 5 is a cross-sectional view of the absorbent article 1 for pets taken along line C-C in FIG. 1. The absorbent article 1 for pets shown in FIGS. 1 to 5 is a disposable diaper for pets that absorbs the urine of pets.

[0030] FIG. 1 shows the absorbent article 1 for pets in a natural state. The natural state means a state in which no external force is applied to the absorbent article 1 for pets. FIG. 2 shows the absorbent article 1 for pets in a deployed state. The deployed state means a state in which the absorbent article 1 for pets is extended until no wrinkles are formed. The skin side Z1 is the side that faces the pet's skin surface when the absorbent article 1 for pets is in a worn state, and the non-skin side Z2 is the side that faces the side opposite to the pet's skin surface when the absorbent article 1 for pets is in a worn state. In the following description, the person who attaches the absorbent article 1 for pets to the pet is referred to as the "user". Typically, the user is the owner of the pet. In the following description, the positional relationship in the deployed state will be described unless otherwise specified.

[0031] In this specification, pets widely include vertebrates and invertebrates, and typically include pet animals such as dogs, cats, rabbits, and hamsters. The absorbent article 1 for pets is particularly preferably used for male pets whose urethral orifice is located in front of the base of the hind legs. As shown in FIG. 2, the absorbent article 1 for pets extends in the short direction X arranged along the front-rear direction (the direction connecting the head and the buttocks) of the pet and the long direction Y arranged along the circumferential direction of the pet's body. The short direction X and the long direction Y are perpendicular to each other. The thickness direction Z is a direction perpendicular to the short direction X and the long direction Y, and includes the skin side Z1 that faces the pet's skin surface in the worn state and the non-skin side Z2 that faces the side opposite to the pet's skin surface in the worn state. The absorbent article 1 for pets is wound around the pet's body and worn.

[0032] The absorbent article 1 for pets includes a main body portion 2. The main body portion 2 has a substantially rectangular (landscape-shaped) planar shape having a short side direction X and a long side direction Y. The four corner portions of the main body portion 2 may be cut so that the width of the main body portion 2 in the short side direction X becomes narrower. The main body portion 2 has a front edge 3 disposed on one end side in the short side direction X and a rear edge 4 disposed on the other end side in the short side direction X. When the absorbent article 1 for pets is worn on a pet, the front edge 3 is disposed on the front paw side of the pet, and the rear edge 4 is disposed on the rear paw side of the pet. In the following description, the direction from the rear edge 4 toward the front edge 3 may be referred to as the front side, and the direction from the front edge 3 toward the rear edge 4 may be referred to as the rear side. Further, the main body portion 2 has a first side edge 5 disposed on one end side in the long side direction Y and a second side edge 6 disposed on the other end side in the long side direction Y. Further, the main body portion 2 has a first portion 2A disposed on one side in the long side direction Y with respect to the center line CL1 of the main body portion 2 in the long side direction Y and a second portion 2B disposed on the other side in the long side direction Y with respect to the center line CL1 of the main body portion 2 in the long side direction Y.

[0033] As shown in FIGS. 1 to 5, the main body portion 2 includes a top sheet 10, a back sheet 20, an absorber 30, and a pair of leak-proof gathers 40. The top sheet 10 constitutes the surface of the main body portion 2 that contacts the pet and is disposed on the skin surface side Z1. The top sheet 10 has, for example, liquid permeability that allows the urine of the pet to permeate toward the absorber 30 side. The top sheet 10 is located substantially at the center in the short side direction X. Examples of the nonwoven fabric constituting the top sheet 10 include an air-through nonwoven fabric, a spunbond nonwoven fabric, or a point-bond nonwoven fabric. The top sheet 10 is joined to the back film 21 and the absorber 30 with, for example, a hot melt adhesive.

[0034] The back sheet 20 forms the surface that is positioned on the outside when worn in the main body portion 2, and is disposed on the non-skin surface side Z2. The back sheet 20 includes a liquid-impermeable back film 21 and a back non-woven fabric 22 disposed on the non-skin surface side Z2 of the back film 21. In the short side direction X, the width of the back film 21 is narrower than the width of the back non-woven fabric 22, and the back non-woven fabric 22 extends beyond both sides of the back film 21 in the short side direction X. Note that in the short side direction X, the back film 21 may have a width substantially the same as the width of the back non-woven fabric 22. The back non-woven fabric 22 constitutes the outermost layer of the absorbent article 1 for pets. The back film 21 is joined to the back non-woven fabric 22 and the absorbent body 30, for example, with a hot melt adhesive.

[0035] The absorbent body 30 is disposed between the front sheet 10 and the back sheet 20. The absorbent body 30 is located substantially at the center of the main body portion 2 and absorbs the urine of the pet. The absorbent body 30 has a substantially rectangular shape extending in the longitudinal direction Y.

[0036] The main body portion 2 includes a first end portion 7 disposed on one side in the longitudinal direction Y, a second end portion 8 disposed on the other end side in the longitudinal direction Y, and a central portion 9 disposed between the first end portion 7 and the second end portion 8. The first end portion 7 is a region located between the absorbent body 30 and the first side edge 5 in the longitudinal direction Y. The second end portion 8 is a region located between the absorbent body 30 and the second side edge 6 in the longitudinal direction Y. The central portion 9 is a region disposed between the first end portion 7 and the second end portion 8 in the longitudinal direction Y. The width of the first end portion 7 in the short side direction X may be narrowed as it approaches the first side edge 5, and the width of the second end portion 8 in the short side direction X may be narrowed as it approaches the second side edge 6. In this case, by narrowing the widths of the first end portion 7 and the second end portion 8, it becomes easier for the user to grip the first end portion 7 and the second end portion 8. The first end portion 7 is a part of the first portion 2A, and the second end portion 8 is a part of the second portion 2B.

[0037] In one embodiment, the absorber 30 includes an absorbent core containing pulp having water absorbency and a superabsorbent polymer (SAP), and a core wrap covering the surface of the absorbent core. As the pulp of the absorbent core, for example, chemical pulp, cellulose fibers such as cellulose fibers, rayon, and acetate are used. As the superabsorbent polymer, for example, starch-based, acrylic acid-based, or amino acid-based particulate or fibrous polymers are used. The absorber 30 may be a SAP sheet that does not contain pulp and is mainly composed of SAP.

[0038] A pair of leak-proof gathers 40 are provided on the surface sheet 10 and are arranged to be spaced apart from each other in the short-side direction X. The pair of leak-proof gathers 40 are arranged to cover both side portions of the surface sheet 10 in the short-side direction X from the skin-side Z1 and extend in the longitudinal direction Y over the entire length of the main body portion 2 in the longitudinal direction Y. The pair of leak-proof gathers 40 are partially joined to the surface sheet 10 or the back sheet 20 outside the absorber 30 in the short-side direction X. The pair of leak-proof gathers 40 stand up with respect to the surface sheet 10 to suppress the urine of the pet excreted on the absorber 30 from leaking in the short-side direction X. The pair of leak-proof gathers 40 includes a front leak-proof gather 41 provided along the front edge 3 and a rear leak-proof gather 51 provided along the rear edge 4. Note that the pair of leak-proof gathers 40 may be formed by turning back the back nonwoven fabric 22 to the surface sheet 10 side outside the main body portion 2 in the short-side direction X. In this case, a part of the back nonwoven fabric 22 turned back to the surface sheet 10 side constitutes the pair of leak-proof gathers 40, and the other part of the back nonwoven fabric 22 constitutes the back sheet 20 of the main body portion 2.

[0039] In one embodiment, the front leak - proof gather 41 includes a side sheet 42 partially fixed to the front - surface sheet 10 or the back - surface sheet 20, and a first elastic member 43 joined to the side sheet 42. The rear leak - proof gather 51 includes a side sheet 52 partially fixed to the front - surface sheet 10 or the back - surface sheet 20, and a first elastic member 53 joined to the side sheet 52. Each of the pair of side sheets 42, 52 is composed of a water - repellent or hydrophobic non - woven fabric. For example, the side sheets 42, 52 are composed of a spunlace non - woven fabric, a spunbond non - woven fabric, a thermal - bond non - woven fabric, a melt - blown non - woven fabric, an SMS non - woven fabric, a needle - punched non - woven fabric, an air - through non - woven fabric, etc.

[0040] Each of the pair of side sheets 42, 52 has a vertically long shape that is long in the longitudinal direction Y, and extends in the longitudinal direction Y over the entire length of the main body portion 2 in the longitudinal direction Y. As shown in FIGS. 3 to 5, the pair of leak - proof gathers 40 extends outside the back - surface film 21. More specifically, the outer edge of the front leak - proof gather 41 in the short - hand direction X coincides with one outer edge of the back - surface non - woven fabric 22 in the short - hand direction X, and together with one outer edge of the back - surface non - woven fabric 22, constitutes the front - end edge 3. The outer edge of the rear leak - proof gather 51 in the short - hand direction X coincides with the other outer edge of the back - surface non - woven fabric 22 in the short - hand direction, and together with the other outer edge of the back - surface non - woven fabric 22, constitutes the rear - end edge 4.

[0041] As shown in FIGS. 2 to 5, the side sheet 42 includes a fixing portion 45 joined to the front - surface sheet 10 or the back - surface sheet 20, and a standing portion 46 not joined to the front - surface sheet 10. At the boundary between the fixing portion 45 and the standing portion 46, a first standing line 45a, a second standing line 45b, and a third standing line 45c are formed.

[0042] The first standing line 45a is disposed between the center line CL2 in the lateral direction X of the main body 2 and the front edge 3 and extends in the longitudinal direction Y. For example, the first standing line 45a is disposed between the edge of the absorber 30 on the front side and the front edge 3. The first standing line 45a is the boundary line between the fixing portion 45 and the standing portion 46 in the lateral direction X and serves as the standing fulcrum for the standing portion 46 in the lateral direction X. Note that the first standing line 45a may partially overlap the absorber 30 when viewed from the thickness direction Z.

[0043] The second standing line 45b is disposed between the center line CL1 in the longitudinal direction Y of the main body 2 and the first side edge 5 and extends in the lateral direction X. For example, the second standing line 45b is disposed between the edge on the first side edge 5 side of the absorber 30 in the longitudinal direction Y and the first side edge 5. The second standing line 45b is the boundary line between the fixing portion 45 and the standing portion 46 in the longitudinal direction Y and serves as the standing fulcrum for the standing portion 46 in the longitudinal direction Y. Note that the second standing line 45b may partially overlap the absorber 30 when viewed from the thickness direction Z. Note that the center line CL1 in the longitudinal direction Y of the main body 2 coincides with the center line in the longitudinal direction Y of the absorber 30.

[0044] The third standing line 45c is disposed between the center line CL1 in the longitudinal direction Y of the main body 2 and the second side edge 6 and extends in the lateral direction X. For example, the third standing line 45c is disposed between the edge on the second side edge 6 side of the absorber 30 in the longitudinal direction Y and the second side edge 6. The third standing line 45c is the boundary line between the fixing portion 45 and the standing portion 46 in the longitudinal direction Y and serves as the standing fulcrum for the standing portion 46 in the longitudinal direction Y. Note that the third standing line 45c may partially overlap the absorber 30 when viewed from the thickness direction Z.

[0045] As described above, in the side sheet 42, the first region R1 on the first side edge 5 side with respect to the second standing line 45b is a part of the fixing portion 45, and the whole of it is joined to the first end portion 7 of the main body portion 2 by a hot melt adhesive. Similarly, in the side sheet 42, the second region R2 on the second side edge 6 side with respect to the third standing line 45c is a part of the fixing portion 45, and the whole of it is joined to the second end portion 8 of the main body portion 2 by a hot melt adhesive. Therefore, as shown in FIGS. 3 and 5, the first region R1 and the second region R2 of the side sheet 42 are non-standing regions that are fixed to the main body portion 2 and do not stand up.

[0046] On the other hand, the standing portion 46 is disposed between the first region R1 and the second region R2, and is a standing region not connected to the main body portion 2. The standing portion 46 is disposed inside the first standing line 45a in the short side direction X, and can stand up with the first standing line 45a as a standing fulcrum between the first region R1 and the second region R2. Since the first region R1 and the second region R2 of the side sheet 42 are joined to the main body portion 2, the standing portion 46 falls inside in the short side direction X when in the unfolded state.

[0047] The inner portion of the standing portion 46 in the short side direction X is folded back, and a first elastic member 43 is disposed between the folded-back standing portions 46. Therefore, as shown in FIG. 2, the first elastic member 43 of the front leak-proof gather 41 is disposed along the inner edge of the standing portion 46. The first elastic member 43 is joined to the side sheet 42 in a state of being stretched in the longitudinal direction Y. The first elastic member 43 is made of an elastic material such as rubber or spandex that can contract in the length direction, for example.

[0048] As shown in FIG. 4, in the standing portion 46 of the side sheet 42, when in the natural state, the first elastic member 43 contracts in the longitudinal direction Y, so that the standing portion 46 stands up starting from the first standing line 45a outside the short side direction X of the absorber 30. By the standing of the standing portion 46 of the front leak-proof gather 41, it is possible to prevent the urine of the pet from leaking forward along the surface of the surface sheet 10.

[0049] The side sheet 52 includes a fixed portion 55 joined to the front sheet 10 or the back sheet 20, and an upright portion 56 not joined to the front sheet 10. A fourth upright line 55a is formed at the boundary between the fixed portion 55 and the upright portion 56.

[0050] The fourth upright line 55a is disposed between the center line CL2 in the lateral direction X of the main body portion 2 and the rear edge 4, and extends in the longitudinal direction Y. For example, the fourth upright line 55a is disposed between the edge of the absorber 30 on the rear side and the rear edge 4. The fourth upright line 55a is the boundary line between the fixed portion 55 and the upright portion 56 in the lateral direction X, and serves as the upright fulcrum for the upright portion 56 in the lateral direction X. In one embodiment, the fourth upright line 55a extends across the entire area of the main body portion 2 in the longitudinal direction Y. Note that the fourth upright line 55a may partially overlap the absorber 30 when viewed from the thickness direction Z.

[0051] The upright portion 56 is disposed inside the fourth upright line 55a in the lateral direction X, and extends across the entire area of the main body portion 2 in the longitudinal direction Y. The upright portion 56 is an upright region not connected to the main body portion 2. The upright portion 56 can stand up with the fourth upright line 55a as the upright fulcrum. Similar to the side sheet 42, both side portions of the side sheet 52 in the longitudinal direction Y may be joined to the main body portion 2. In this case, the upright portion 56 falls inward in the lateral direction X when in the deployed state.

[0052] The inner portion of the upright portion 56 in the lateral direction X is folded back, and a first elastic member 53 is disposed between the folded-back upright portions 56. Therefore, as shown in FIG. 2, the first elastic member 53 of the rear leak-proof gather 51 is disposed along the inner edge of the upright portion 56. The first elastic member 53 is joined to the side sheet 52 in a state of being stretched in the longitudinal direction Y. The first elastic member 53 is made of a stretchable material such as rubber or spandex that can contract in the length direction, for example.

[0053] As shown in FIGS. 3, 4, and 5, the standing portion 56 of the side sheet 52 stands up starting from the fourth standing line 55a outside the absorber 30 in the short side direction X when the first elastic member 53 contracts in the longitudinal direction Y in the natural state. By the standing of the standing portion 56 of the rear leak - proof gather 51, it is possible to prevent the urine of the pet from leaking along the surface of the surface sheet 10.

[0054] The maximum standing height H1 of the front leak - proof gather 41 with respect to the main body portion 2 is the same as the maximum standing height H2 of the rear leak - proof gather 51 with respect to the main body portion 2. The maximum standing height H1 corresponds to the height of the top of the front leak - proof gather 41 with respect to the main body portion 2 when the front leak - proof gather 41 stands up perpendicular to the main body portion 2. In other words, the maximum standing height H1 can also be said to be the length along the surface of the front leak - proof gather 41 from the first standing line 45a to the top of the standing portion 46 in a cross - section along the short side direction X. Similarly, the maximum standing height H2 corresponds to the height of the top of the rear leak - proof gather 51 with respect to the main body portion 2 when the rear leak - proof gather 51 stands up perpendicular to the main body portion 2. In other words, the maximum standing height H2 can also be said to be the length along the surface of the rear leak - proof gather 51 from the fourth standing line 55a to the top of the standing portion 56 in a cross - section along the short side direction X. Note that the maximum standing height H1 of the front leak - proof gather 41 may be different from the maximum standing height H2 of the rear leak - proof gather 51. For example, the maximum standing height H1 of the front leak - proof gather 41 may be higher than the maximum standing height H2 of the rear leak - proof gather 51. By making the maximum standing height H1 higher than the maximum standing height H2, when the absorbent article 1 for pets is worn so that the front leak - proof gather 41 is arranged on the head side of the pet, the urine vigorously discharged from the pet can be blocked by the front leak - proof gather 41, so that urine leakage can be effectively suppressed. Also, the maximum standing height H2 of the rear leak - proof gather 51 may be higher than the maximum standing height H1 of the front leak - proof gather 41. In this case, the urine flowing to the rear can be blocked by the rear leak - proof gather 51, so that urine leakage can be effectively suppressed.

[0055] The main body portion 2 further includes a plurality of second elastic members 60 that are stretchable in the longitudinal direction Y. The plurality of second elastic members 60 are disposed between the surface sheet 10 and the back sheet 20 and extend in the longitudinal direction Y. The plurality of second elastic members 60 impart stretchability in the longitudinal direction Y to the main body portion 2. In one embodiment, the second elastic member 60 is thread rubber. The second elastic member 60 may be a stretchable nonwoven fabric or a stretchable film. As shown in FIG. 2, the second elastic member 60 extends over the entire area of the main body portion 2 in the longitudinal direction Y. Thereby, stretchability in the longitudinal direction Y can be imparted to the entire area of the main body portion 2, and the main body portion 2 can be contracted so as to follow changes in the body shape and posture of the pet. Therefore, the fit of the absorbent article 1 for pets is effectively improved. Note that the second elastic member 60 does not necessarily extend over the entire area of the main body portion 2 in the longitudinal direction Y.

[0056] The plurality of second elastic members 60 are arranged along the short side direction X. In one embodiment, the second elastic members 60 may be arranged at equal intervals along the short side direction X between a pair of front edges 3 and rear edges 4 (a pair of side edges) in the short side direction X. Thereby, the uniformity of the stretching force of the main body portion 2 in the short side direction X can be enhanced.

[0057] The plurality of second elastic members 60 overlap the first portion 2A and the second portion 2B when viewed from the thickness direction Z. Therefore, the first portion 2A and the second portion 2B of the main body portion 2 have stretchability. Also, the plurality of second elastic members 60 overlap the first end 7 and the second end 8 when viewed from the thickness direction Z. Therefore, the first end 7 and the second end 8 of the main body portion 2 have stretchability. In one embodiment, the first portion 2A and the second portion 2B may have the same shrinkage rate, and the first end 7 and the second end 8 may have the same shrinkage rate. When the length in the longitudinal direction Y of the first portion 2A or the second portion 2B in the natural state is L1 and the length in the longitudinal direction Y of the first portion 2A or the second portion 2B in the unfolded state is L2, the shrinkage rate [%] is represented by (L2 - L1) / L2 × 100.

[0058] The plurality of second elastic members 60 are disposed between the surface sheet 10 and the back sheet 20, and are adhered to the surface sheet 10 or the back sheet 20 using a hot melt adhesive in a state of being extended in the longitudinal direction Y. In particular, as shown in FIG. 4, a part of the plurality of second elastic members 60 is disposed between the absorber 30 and the back sheet 20. That is, a part of the plurality of second elastic members 60 overlaps the absorber 30 when viewed from the thickness direction Z, and extends in the longitudinal direction Y so as to straddle the absorber 30. Thereby, the absorber 30 is lifted over the entire area of the absorber 30 in the longitudinal direction Y by the contraction force of these second elastic members 60, so that the sagging of the absorber 30 is suppressed when urine is absorbed by the absorber 30. As described above, by disposing the plurality of second elastic members 60 on the non-skin side Z2 with respect to the absorber 30, it is possible to prevent the absorption of urine by the absorber 30 from being inhibited by the plurality of second elastic members 60. Further, since the plurality of second elastic members 60 are prevented from directly contacting the body of the pet when the absorbent article 1 for pets is worn, the wearing feeling of the absorbent article 1 for pets can be improved. Further, as shown in FIG. 2, a part of the plurality of second elastic members 60 also overlaps an engaging portion 70 described later when viewed from the thickness direction Z. Note that an intermediate sheet made of a nonwoven fabric may be disposed between a part of the plurality of second elastic members 60 and the absorber 30.

[0059] Another part of the plurality of second elastic members 60 is disposed between the surface sheet 10 and the back sheet 20, and is adhered to the surface sheet 10 or the back sheet 20 using a hot melt adhesive in a state of being extended in the longitudinal direction Y. These second elastic members 60 are disposed outside the absorber 30 in the short hand direction X and do not overlap the absorber 30 when viewed from the thickness direction Z.

[0060] Note that the plurality of second elastic members 60 may be joined to the surface sheet 10 or the back sheet 20 without using a hot melt adhesive. For example, the plurality of second elastic members 60 may be joined to the surface sheet 10 or the back sheet 20 by sonic processing.

[0061] The absorbent article 1 for pets further includes an engaging portion 70. The engaging portion 70 is a member that engages the first portion 2A and the second portion 2B. As shown in FIGS. 1 to 3, the engaging portion 70 has a rectangular shape that is long in the short direction X and is provided at the first end portion 7 of the first portion 2A. The engaging portion 70 is provided on the outer surface of the back sheet 20. The engaging portion 70 is, for example, a mechanical fastener having a large number of hooks and can engage with the surface sheet 10 from the skin surface side Z1. Note that the engaging portion 70 may be engageable with the second portion 2B via a target portion provided on the surface sheet 10.

[0062] The absorbent article 1 for pets configured as described above can be worn on a pet as follows. First, the user presses the first end portion 7 of the absorbent article 1 for pets against the pet's back and holds the vicinity of the first end portion 7 with one hand. Next, the user holds the second end portion 8 of the absorbent article 1 for pets with the other hand and wraps the absorbent article 1 for pets around the pet's abdomen so as to cover it. At this time, the front leak-preventing gather 41 is disposed in front of the pet with respect to the urethral orifice, and the rear leak-preventing gather 51 is disposed behind the pet with respect to the urethral orifice, and the absorbent article 1 for pets is worn. Next, after the user pulls up the second end portion 8 upward so that the absorbent article 1 for pets adheres closely to the pet's body circumference, the user engages the surface sheet 10 of the second end portion 8 with the engaging portion 70. As a result, the absorbent article 1 for pets is worn on the pet at an appropriate position. At this time, as the plurality of second elastic members 60 contract in the longitudinal direction Y, the absorbent article 1 for pets adheres closely to the pet's body. Further, since the plurality of second elastic members 60 overlap the engaging portion 70 when viewed in the thickness direction Z, the engaging portion 70 is pulled along the longitudinal direction Y by the contraction force of the second elastic members 60, and the hooks of the engaging portion 70 are entangled with the fibers of the surface sheet 10. As a result, the first end portion 7 and the second end portion 8 are firmly engaged, and the absorbent article 1 for pets is prevented from falling off unintentionally.

[0063] As described above, in the absorbent article 1 for pets, since the plurality of second elastic members 60 arranged so as to overlap the absorber 30 contract so as to follow changes in the body posture and body shape of the pet, the fit of the absorbent article 1 for pets is improved. In particular, in the absorbent article 1 for pets, since a part of the plurality of second elastic members 60 is arranged so as to overlap the absorber 30, even when urine is absorbed by the absorber 30, the absorber 30 is lifted by the contraction force of the plurality of second elastic members 60. Therefore, the sagging of the absorber 30 is suppressed, and the fit of the absorbent article 1 for pets can be maintained. As a result, according to the absorbent article 1 for pets, urine leakage can be suppressed.

[0064] Next, an absorbent article for pets according to another embodiment will be described. FIG. 6 is a plan view of the absorbent article 1A for pets according to another embodiment as viewed from the skin side Z1. The absorbent article 1A for pets shown in FIG. 6 is different from the absorbent article 1 for pets shown in FIG. 1 in that it includes a plurality of second elastic members 60A instead of the plurality of second elastic members 60. In the following description, the differences from the absorbent article 1 for pets will be mainly described, and overlapping descriptions will be omitted.

[0065] The main body portion 2 of the absorbent article 1A for pets includes a plurality of second elastic members 60A that are stretchable in the short side direction X. The plurality of second elastic members 60A are arranged between the surface sheet 10 and the back sheet 20 and extend in the short side direction X. The plurality of second elastic members 60A impart stretchability in the short side direction X to the main body portion 2. As shown in FIG. 6, the plurality of second elastic members 60A extend over the entire area of the main body portion 2 in the short side direction X. Thereby, stretchability in the short side direction X can be imparted to the entire area of the main body portion 2, and the main body portion 2 can be contracted so as to follow changes in the body shape and posture of the pet. Note that the second elastic member 60A does not necessarily have to extend over the entire area of the main body portion 2 in the short side direction X.

[0066] The plurality of second elastic members 60A are arranged along the longitudinal direction Y. More specifically, the second elastic members 60A are arranged at equal intervals along the longitudinal direction Y between a pair of first side edges 5 and second side edges 6 in the longitudinal direction Y. Thereby, the uniformity of the expansion and contraction force of the main body portion 2 in the longitudinal direction Y can be enhanced.

[0067] The plurality of second elastic members 60A are disposed between the surface sheet 10 and the back sheet 20, and are adhered to the surface sheet 10 or the back sheet 20 using a hot melt adhesive in a state of being extended in the short transverse direction X. At least a part of the plurality of second elastic members 60A overlaps the absorber 30 when viewed from the thickness direction Z, and extends in the short transverse direction X so as to straddle the absorber 30.

[0068] Since the absorbent article 1A for pets described above includes a plurality of second elastic members 60A that are stretchable in the short transverse direction X, the plurality of second elastic members 60A expand and contract following changes in the body shape and posture of the pet (for example, an action of the pet stretching its body) during wearing. As a result, the fit of the absorbent article 1A for pets is improved.

[0069] Next, an absorbent article for pets according to yet another embodiment will be described. FIG. 7 is a plan view of an absorbent article 1B for pets according to yet another embodiment as viewed from the skin side Z1. The absorbent article 1B for pets shown in FIG. 7 mainly differs from the absorbent article 1 for pets shown in FIG. 1 in that it includes a plurality of second elastic members 60B instead of the plurality of second elastic members 60. In the following description, the differences from the above-described absorbent article 1 for pets will be mainly described, and overlapping descriptions will be omitted.

[0070] The main body 2 of the absorbent article 1B for pets includes a plurality of second elastic members 60B that are stretchable in the longitudinal direction Y. The plurality of second elastic members 60B are disposed between the surface sheet 10 and the back sheet 20 and extend in the longitudinal direction Y. As shown in FIG. 7, the plurality of second elastic members 60B extend between the center line CL1 in the longitudinal direction Y of the main body 2 and the second side edge 6. Therefore, when viewed from the thickness direction Z, the plurality of second elastic members 60B overlap a part of the second portion 2B and the absorber 30. Therefore, a stretchable region R3 that stretches in the longitudinal direction Y is formed in the second portion 2B. On the other hand, when viewed from the thickness direction Z, the plurality of second elastic members 60B do not overlap the first portion 2A. Therefore, a non-stretchable region R4 that does not include the plurality of second elastic members 60B is formed in the first portion 2A.

[0071] In the absorbent article 1B for pets, since the plurality of second elastic members 60B are arranged so as not to overlap the engaging portion 70 provided at the first end 7 of the first portion 2A, the engaging portion 70 is prevented from being deformed in a wavy manner by the contraction force of the plurality of second elastic members 60B. If the plurality of second elastic members 60B overlap a part of the second end 8 and the absorber 30, the end portion of the plurality of second elastic members 60B on the first side edge 5 side may not be located on the center line CL1.

[0072] The plurality of second elastic members 60B are disposed between the surface sheet 10 and the back sheet 20 and are adhered to the surface sheet 10 or the back sheet 20 using a hot melt adhesive in a state of being stretched in the longitudinal direction Y. A part of the plurality of second elastic members 60B overlaps the absorber 30 when viewed from the thickness direction Z and extends from the inside to the outside of the absorber 30 in the longitudinal direction Y. Thereby, since the absorber 30 can be lifted from the outside of the absorber 30 in the longitudinal direction Y, the sagging of the absorber 30 is suppressed.

[0073] As described above, the first portion 2A includes the non-stretchable region R4, and the second portion 2B includes the stretchable region R3. In the embodiment shown in FIG. 7, the entire first portion 2A constitutes the non-stretchable region R4, and the entire second portion 2B constitutes the stretchable region R3. Therefore, the shrinkage rate of the second portion 2B is higher than that of the first portion 2A. By making the shrinkage rate of the second portion 2B higher than that of the first portion 2A, it becomes easy to align the absorbent article 1B for pets by applying the first portion 2A with a relatively low shrinkage rate to the body of the pet. When engaging the first portion 2A and the second portion 2B, since the second portion 2B with a relatively high shrinkage rate shrinks, it is possible to reduce the looseness when the absorbent article 1B for pets is worn. Note that a part of the plurality of second elastic members 60B may extend up to the middle of the first portion 2A, and only a part of the first portion 2A may constitute the non-stretchable region R4. Similarly, only a part of the second portion 2B may constitute the stretchable region R3. Even in this case, if the shrinkage rate of the second portion 2B is higher than that of the first portion 2A, the looseness of the absorbent article 1B for pets can be reduced.

[0074] Next, an absorbent article for pets according to still another embodiment will be described. FIG. 8 is a plan view of the absorbent article 1C for pets according to still another embodiment as viewed from the skin side Z1. The absorbent article 1C for pets shown in FIG. 8 is different from the absorbent article 1 for pets shown in FIG. 1 in that it includes a plurality of second elastic members 60C instead of the plurality of second elastic members 60, and further includes a target portion 73.

[0075] The absorbent article 1C for pets includes a plurality of second elastic members 60C that are stretchable in the longitudinal direction Y. The plurality of second elastic members 60C are disposed between the top sheet 10 and the back sheet 20 and extend in the longitudinal direction Y. As shown in FIG. 8, the plurality of second elastic members 60C extend between the center line CL1 in the longitudinal direction Y of the main body portion 2 and the first side edge 5. Therefore, when viewed from the thickness direction Z, the plurality of second elastic members 60C overlap a part of the first portion 2A and the absorber 30. Accordingly, a stretchable region R3 that stretches in the longitudinal direction Y is formed in the first portion 2A. On the other hand, when viewed from the thickness direction Z, the plurality of second elastic members 60C do not overlap the second portion 2B. Accordingly, a non-stretchable region R4 that does not include the plurality of second elastic members 60C is formed in the second portion 2B.

[0076] The plurality of second elastic members 60C are disposed between the top sheet 10 and the back sheet 20 and are adhered to the top sheet 10 or the back sheet 20 using a hot melt adhesive in a state of being stretched in the longitudinal direction Y. A part of the plurality of second elastic members 60C overlaps the absorber 30 when viewed from the thickness direction Z and extends from the inside to the outside of the absorber 30 in the longitudinal direction Y. Thereby, since the absorber 30 can be lifted from the outside of the absorber 30 in the longitudinal direction Y, the sagging of the absorber 30 is suppressed.

[0077] In the absorbent article 1C for pets, an engaging portion 70 is provided on the surface of the top sheet 10 at the first end 7 of the first portion 2A. On the other hand, a target portion 73 is provided on the outer surface of the back sheet 20 at the second end 8 of the second portion 2B. The engaging portion 70 can be engaged with the target portion 73 from the non-skin surface side Z2. Note that the absorbent article 1C for pets may not include the target portion 73, and the engaging portion 70 may be directly engaged with the back sheet 20. The plurality of second elastic members 60C overlap the engaging portion 70 when viewed from the thickness direction Z.

[0078] As described above, in the pet absorbent article 1C, the first portion 2A includes the stretchable region R3, and the second portion 2B includes the non-stretchable region R4. In the embodiment shown in FIG. 8, the entire first portion 2A constitutes the stretchable region R3, and the entire second portion 2B constitutes the non-stretchable region R4. Therefore, the shrinkage rate of the first portion 2A is higher than that of the second portion 2B. By making the shrinkage rate of the first portion 2A higher than that of the second portion 2B, it becomes easier to position the pet absorbent article 1C by applying the second portion 2B, which has a relatively low shrinkage force, against the body of the pet. When engaging the first portion 2A and the second portion 2B, since the first portion 2A, which has a relatively high shrinkage rate, shrinks, loosening during the wearing of the pet absorbent article 1C can be reduced. Note that a part of the plurality of second elastic members 60C may extend to the middle of the second portion 2B, and only a part of the second portion 2B may constitute the non-stretchable region R4. Similarly, only a part of the first portion 2A may constitute the stretchable region R3. Even in this case, if the shrinkage rate of the first portion 2A is higher than that of the second portion 2B, loosening of the pet absorbent article 1C can be reduced.

[0079] The pet absorbent article 1C can be worn on a pet as follows. First, the user presses the second end portion 8 of the pet absorbent article 1C against the back of the pet and holds the vicinity of the second end portion 8 with one hand. Next, the user holds the first end portion 7 of the pet absorbent article 1C with the other hand and wraps the pet absorbent article 1C around the abdomen of the pet. Next, after the user pulls up the first end portion 7 upward so that the pet absorbent article 1C closely adheres to the pet's torso, the engaging portion 70 is engaged with the target portion 73 at the second end portion 8. By engaging the engaging portion 70 and the target portion 73 in this way, it becomes easier to engage the first end portion 7 and the second end portion 8 at an appropriate position, and thus it becomes easier to maintain the engaged state of the first end portion 7 and the second end portion 8.

[0080] FIG. 9 is a cross-sectional view schematically showing a pet absorbent article 1D according to still another embodiment. The pet absorbent article 1D is different from the pet absorbent article 1 shown in FIG. 1 in that a plurality of second elastic members 60 are arranged on the skin side Z1 with respect to the absorber 30.

[0081] As shown in FIG. 9, in the absorbent article 1D for pets, a part of the plurality of second elastic members 60 is disposed between the absorber 30 and the surface sheet 10. That is, a part of the plurality of second elastic members 60 is disposed on the skin side Z1 with respect to the absorber 30. Thereby, since the absorber 30 is lifted from above the absorber 30, it is possible to suppress the absorber 30 from being pressed against the body of the pet.

[0082] FIG. 10 is a cross-sectional view schematically showing an absorbent article 1E for pets according to still another embodiment. The absorbent article 1E for pets shown in FIG. 10 is different from the absorbent article 1 for pets shown in FIG. 1 in that the main body portion 2 includes a second elastic member 60E instead of the plurality of second elastic members 60.

[0083] The second elastic member 60E is a stretchable sheet such as spandex, for example. The second elastic member 60E includes, for example, elastic yarn made of polyurethane and stretches in the short direction X and the long direction Y. In one embodiment, the second elastic member 60E is provided on the outer surface of the back sheet 20 so as to overlap the absorber 30 when viewed from the thickness direction Z, and is joined to the outer surface of the back sheet 20 using a hot melt adhesive. The second elastic member 60E may be provided over the entire outer surface of the back sheet 20, or may be provided on a part of the outer surface of the back sheet 20. Note that the second elastic member 60E does not have to be provided on the outer surface of the back sheet 20 as long as it is disposed on the non-skin side Z2 with respect to the absorber 30. By using a stretchable sheet as the second elastic member 60E, unevenness is less likely to be formed on the surface of the main body portion 2, so that the wearing feeling of the absorbent article 1E for pets can be improved.

[0084] As described above, the absorbent articles for pets according to various embodiments have been described. However, the present invention is not limited to the above-described embodiments, and various modifications can be configured without changing the gist of the invention. That is, it should be noted that the above-described embodiments are for illustrative purposes and do not limit the scope of the present invention.

[0085] For example, although the absorbent articles 1, 1A, 1B, 1C, 1D for pets described above include a plurality of second elastic members 60, 60A, 60B, 60C, 60D, it is sufficient if at least one second elastic member 60, 60A, 60B, 60C, 60D is provided.

[0086] In the absorbent article 1B for pets, although a plurality of second elastic members 60B extend along the longitudinal direction Y from the center line CL1 to the second side edge 6, the plurality of second elastic members 60B may extend along the longitudinal direction Y from any position between the edge on the first side edge 5 side of the absorber 30 and the edge on the second side edge 6 side of the absorber 30 to the second side edge 6. Similarly, in the absorbent article 1C for pets, the plurality of second elastic members 60C may extend along the longitudinal direction Y from any position between the edge on the first side edge 5 side of the absorber 30 and the edge on the second side edge 6 side of the absorber 30 to the first side edge 5.

[0087] In the absorbent articles 1, 1A, 1B, 1C, 1D, 1E for pets described above, the front leak - proof gather 41 may not include the first elastic member 43, and the rear leak - proof gather 51 may not include the first elastic member 53. Also, the absorbent articles 1, 1A, 1B, 1C, 1D, 1E for pets may not include the leak - proof gather 40.

[0088] In the above - described embodiments, although the plurality of second elastic members 60, 60A, 60B, 60C, 60D extend in the short - hand direction X or the longitudinal direction Y, the plurality of second elastic members 60, 60A, 60B, 60C, 60D may extend in a lattice pattern in the short - hand direction X and the longitudinal direction Y.

[0089] In each of the absorbent articles 1, 1A, 1B, 1C, 1D, 1E for pets described above, the surface sheet 10 in the first portion 2A and the surface sheet 10 in the second portion 2B may engage with each other. Also, in each of the absorbent articles 1, 1A, 1B, 1C, 1D, 1E for pets, the back sheet 20 in the first portion 2A and the back sheet 20 in the second portion 2B may engage with each other. The above - described various embodiments can be combined within a non - conflicting range.
