A landing part 22 is provided.

<Absorption panel>
The absorbent panel 14 is positioned between a first end edge 14a and a second end edge 14b facing each other in the longitudinal direction Y and extending in the lateral direction X, and is vertically concavely curved between the first and

second end edges

14a and 14b. A contour is defined by both side edges 14c extending in the direction. Both side edges 14c of the intermediate region 13 are a pair of first concave curved portions 19a extending inwardly in the lateral direction X from the inner end of the ventral region 11, and the inner side of the lateral side X from the inner end of the dorsal region 12. It has a pair of 2nd concave part 19b extended in the shape of a bend, and a pair of straight part 19c located between the 1st concave part 19a and the 2nd concave part 19b. The absorbent panel 14 is formed of a fiber nonwoven fabric, a porous plastic film, a laminate sheet thereof, and the like, and is a liquid-permeable inner layer sheet (inner layer) 27 located on the body-facing surface side, a moisture-permeable plastic film, a fiber nonwoven fabric, and the like And a liquid-impervious outer layer sheet (outer layer) 28 located on the non-body-side facing surface side, and an absorber 29 interposed between the inner and

outer layer sheets

27, 28. The inner layer sheet 27 and the outer layer sheet 28 extend from the peripheral edge of the absorber 29, and are applied to the inner surface of at least one of the inner and

outer layer sheets

27 and 28 at the extended portion, for example, hot melt bonding They are joined to each other via an agent (not shown).

Referring to FIGS. 2 and 6, the intermediate region 13 is located on the ventral region 11 side for convenience of explanation, and includes a first region 16 extending from the first concave curved portion 19 a toward the horizontal axis Q, and a dorsal region. 12 and is divided into a second area 17 extending from the second concave portion 19b toward the horizontal axis Q and a central area 18 located between the first and

second areas

16 and 17. The absorber 29 is located in the central region 18, and the first area 16 is located between the inner end 11 a of the ventral region 11 and a first end edge 51 a described later of the absorber 29, and the second region 16. The area 17 is located between the inner end 12 a of the back side area 12 and the second end edge 51 b described later of the absorber 29. In the intermediate area 13, the first area 16, the second area 17, and the central area 18 may be defined by, for example, dividing the longitudinal dimension Y of the intermediate area 13 into three equal parts, The dimension of the

second area

16, 17 in the vertical direction Y may be larger than the dimension of the central area 18 in the vertical direction Y, or vice versa. If the dimension of the first area 16 in the vertical direction Y is larger than the dimension of the central area 18 in the vertical direction Y, the following operations and effects can be achieved.

Between the inner layer sheet 27 and the outer layer sheet 28 and on the non-body-side facing surface side of the absorbent body 29, a leak-proof sheet 30 formed of a liquid-impermeable and moisture-permeable plastic film is disposed, It is fixed to the inner surface of any one of the inner and

outer layer sheets

27 and 28. In addition, a pair of flap sheets 32 that are positioned symmetrically with respect to the longitudinal axis P are disposed outside the absorbent body 29 in the lateral direction X on the body-side facing surface of the inner layer sheet 27.

When the absorbent article 10 is worn on the pet animal 5, the first fastening element 20 of the pair of fastening tabs 15 and the second fastening element 21 located on the outer surface of the dorsal region 12 are hooked together, thereby the waist opening 33. And a pair of leg opening 34 is formed (refer FIG. 1).

2 and 3, in the ventral region 11 of the absorbent panel 14, a belt-shaped ventral ribbon elastic body (ventral elastic element) extending in the lateral direction X between the outer layer sheet 28 and the leak-proof sheet 30 is provided. 35 is arranged. The ventral ribbon elastic body 35 is formed of a natural or synthetic rubber or foamed polyurethane string, a flat rubber (urethane foam), or a ribbon-like elastic body. In this embodiment, the elasticity of the foamable polyurethane is used. The body is placed. The ventral ribbon elastic body 35 has a desired rigidity and defines a first high-rigidity region 61 in the ventral region 11. The ventral ribbon elastic body 35 has a required width dimension (dimension in the longitudinal direction Y) and length in order to apply a contracting force to a relatively wide range of the ventral region 11 to fit the body of the pet animal 5. A belt-like shape having dimensions (dimensions in the lateral direction X) is preferable. Referring to FIG. 6, specifically, the length dimension (dimension in the transverse direction X) W1 of the ventral ribbon elastic body 35 is about 50 to 400 mm, and the width dimension (dimension in the longitudinal direction Y) L1 is about 10 to 60 mm. It is.

2 and 4, the outer layer sheet 28 and the flap sheet 32 extend further outward in the lateral direction X from both side edges of the inner layer sheet 27 and the leak-proof sheet 30 in the ventral

dorsal regions

11 and 12. Thus, an abdominal side flap 38 and a back side flap 39 are formed. A proximal portion 15a of a pair of fastening tabs 15 is integrally interposed between both side edges of the outer layer sheet 28 and the flap sheet 32 forming the ventral side flap 38, and the inner surfaces of both

sheets

27 and 28 It is fixed to.

In the fastening system comprising the first fastening element 20 and the second fastening element 21, if it has the required peel strength, the first fastening element 20 is replaced with a hook group and a pressure sensitive adhesive is used. May be. At this time, in order to protect the first fastening element 20, it is preferable to cover the surface of the first fastening element 20 with a separator coated with silicon. The base sheet for forming the fastening tab 15 is preferably formed from a sheet material having a relatively high rigidity and tensile strength, such as a plastic film, a fiber nonwoven fabric, a laminate thereof, or a kraft paper. Further, as long as the required effects of the present invention are achieved, the first fastening element 20 provided on the ventral side flap 38 can be releasably hooked directly on the second fastening element 21 without using the fastening tab 15. It may be.

The flap sheet 32 includes a proximal portion that forms part of both side edges 14c, and a front end fixing portion (fixing portion) 41a that is fixed to the body-side facing surfaces of the inner layer sheet 27 and the outer layer sheet 28 in the ventral

dorsal regions

11 and 12. And a rear end fixing portion 41b and a distal portion 42 that extends in the longitudinal direction Y between the front and rear

end fixing portions

41a and 41b and is formed by folding the inner edge of the flap sheet 32 inward. For example, two strand-like or string-like side elastic bodies (side elastic elements) 43 extending in the vertical direction Y are provided on the proximal portion of the flap sheet 32 at the outer sides in the lateral direction X of both side edges of the leak-proof sheet 30. For example, a hot melt adhesive (not shown) is attached between the outer layer sheet 28 and the both side portions of the outer layer sheet 28 so as to be shrinkable. For example, a single strand-like or string-like flap elastic body (flap elastic element) 44 extending in the longitudinal direction Y is attached to the distal portion 42 so as to be contracted in an extended state. FIG. 5 is a diagram schematically showing a cross section of the ventral region 11 in the wearing state of the absorbent article 10, but the distal portion 42 is formed on the body side of the inner layer sheet 27 by the contraction action of the flap elastic body 44. A pair of containment flaps 46 to prevent the excrement from leaking from the opposite direction and from the lateral direction X, and a space 47 is formed between the containment flaps 46 and the inner layer sheet 27.

In the present embodiment, the side elastic body 43 and the flap elastic body 44 are, for example, about 2.0 to 3.0 times, preferably 2.2 to 2 times, a string-like or strand-like elastic material having a fineness of 280 to 500 dtex. .Elongated to 5 times and attached so as to be contractible, the number of

elastic bodies

43, 44 is increased or a plurality of elastic bodies are provided by the required contracting force required for each

elastic body

43,44 The separation dimension (pitch) at 43 and 44 can be set as appropriate. Further, the elastic materials constituting the

elastic bodies

43 and 44 can be set to be different from each other without making the fineness and the expansion ratio uniform. Specifically, for example, among the plurality of elastic materials constituting the side elastic body 43, the fineness of the elastic material that is located on the outermost side in the horizontal direction X is set to the fineness of the elastic material that is located on the innermost side in the horizontal direction X. Alternatively, the former may be made smaller than the latter, or the fineness or expansion ratio of each elastic material may be increased (or decreased) from the inner side to the outer side in the lateral direction X.

In the present embodiment, the side elastic body 43 extends in a series in the longitudinal direction Y in the entire area in the longitudinal direction Y of the absorption panel 14, that is, between the first end edge 14a and the second end edge 14b. On the other hand, the flap elastic body 44 extends from the first edge 14 a to the back region 12 side of the absorber 29. The side elastic body 43 and the flap elastic body 44 have a stretchable functional portion that substantially exhibits stretchability and a non-stretchable functional portion that does not substantially exhibit stretchability. When the

elastic bodies

43 and 44 are attached to the sheet, the non-stretchable function part is a so-called snapback (the non-fixed part of the

elastic bodies

43 and 44 that is not fixed to the sheet is fixed to the sheet by its contraction. It returns to the vicinity of the joint end). The side elastic body 43 and the flap elastic body 44 are positioned so that their end portions overlap each other in plan view with both end portions of the ventral ribbon elastic body 35, and the end portions substantially exhibit stretchability. A stretchable functional part is preferred. In such a case, the force of pulling the first end portion 14a of the absorption panel 14 to the dorsal region 12 side by the contraction force of both

elastic bodies

43, 44 acts, and the entire side edges 14c are in a tensioned state, absorbing. Since the deployed form of the absorbent article 10 is maintained, the absorbent article 10 is not greatly deformed when a part of the absorbent article 10 is passed between the rear limbs 7 of the pet animal 5 when worn. Wearing operation can be done smoothly.

2 and 3, the absorber 29 is interposed between the inner and

outer layer sheets

27 and 28, is located only in the intermediate region 13, is water-insoluble, and has a so-called high water absorption performance of 10 times or more of its own mass. Semi-rigid absorbent core 51 formed from a mixture containing absorbent polymer (SAP) particles, wood fluff pulp, and optionally thermoplastic fibers, and a hydrophilic and liquid diffusing nonwoven fabric enclosing it Or the core wrap sheet | seat 52 formed from the tissue paper. The core wrap sheet 52 is joined to the inner layer sheet 27 and / or the leak-proof sheet 30 via, for example, a hot melt adhesive, and extends from the side edge of the absorbent core 51 to the outside in the lateral direction X. Referring to FIG. 6, the length L2 of the absorbent body 29 in the longitudinal direction Y is about 230 mm in the absorbent article 10 of the present embodiment used for a small dog, and the length of the absorbent body 29 in the lateral direction X. The dimension W2 is about 100 mm. The vertical and horizontal length dimensions L2, W2 of the absorbent body 29 are greatly different between the absorbent article for small dogs and the absorbent article for large dogs. However, the ratio of the longitudinal dimension Y of the absorbent body 29 to the longitudinal dimension Y of the absorbent article 10 is about 30% in this embodiment, and preferably about 15 to 35%. Further, the ratio of the length dimension W2 in the transverse direction X of the absorbent body 29 to the dimension W4 in the transverse direction X of the absorbent article 10 is about 40% in this embodiment, and preferably about 20 to 60%. In the present embodiment, the length dimension L4 in the longitudinal direction Y of the absorbent article 10 is about 450 mm, and the length dimension W4 in the lateral direction X of the absorbent article 10 is about 250 mm.

Referring to FIG. 6, in the arrangement region of the absorbent body 29 in the intermediate region 13, the absorbent core 51 having a relatively high rigidity is positioned, and the arrangement region of the ventral ribbon elastic body 35 in the ventral region 11 is also arranged. Since the elastic body attached in the stretched state is arranged, the rigidity of these regions is higher than that of the portion formed only from the sheet member. Therefore, on the ventral region 11 side, the first high-rigidity region 61 in which the ventral-side ribbon elastic body 35 is disposed and the second high-rigidity region (the portion in which the absorber 29 is disposed) 62 in which the absorber 29 is disposed. Specifically, a low-rigidity region 63 located between the inner end edge 35a of the ventral ribbon elastic body 35 and the first end edge 51a of the absorbent body 29 is defined.

The first high-rigidity region 61 is formed from the

sheets

27, 28, 30 and the ventral ribbon elastic body 35, and the second high-rigidity region 62 is formed from the

sheets

27, 28, 30 and the absorber 29, and has low rigidity. The region 63 is formed from the

sheets

27, 28, and 30. That is, the number of components that form the low-rigidity region 63 (elements that constitute the absorbing panel 14 such as sheet members and elastic materials) is the component that forms the first and second high-

rigidity regions

61 and 62. Less than the number of stacked layers. Referring to FIG. 6, the length dimension L3 in the longitudinal direction Y of the low-rigidity region 63 is preferably about 22 to 112 mm in the absorbent article 10 of the present embodiment used for a small dog, and the low-rigidity region 63 In the present embodiment, the length dimension W3 in the lateral direction X is about 115 mm, and preferably about 80 to 140 mm. The vertical and horizontal length dimensions L3 and W3 of the low-rigidity region 63 are greatly different between the absorbent article for small dogs and the absorbent article for large dogs. However, the ratio of the length dimension L3 in the longitudinal direction Y of the low rigidity region 63 to the dimension L4 in the longitudinal direction Y of the absorbent article 10 is preferably about 5 to 25%. Further, the ratio of the length dimension W3 in the lateral direction X of the low rigidity region 63 to the dimension W4 in the lateral direction X of the absorbent article 10 is preferably about 30 to 60%. However, the length dimension L3 in the vertical direction Y of the low rigidity region 63 is larger than the length dimension W2 in the horizontal direction X of the absorber 29.

Referring to FIGS. 2 and 3, a cutting line (perforation) 55 for forming an opening (insertion hole) through which the tail 6 of the pet animal 5 is inserted is disposed in the second region 17 of the intermediate region 13. . The cutting line 55 is substantially U-shaped, and penetrates the inner layer sheet 27, the leak-proof sheet 30, and the outer layer sheet 28 that overlap each other in plan view. An opening is formed by cutting a part of the absorbent panel 14 along the cutting line 55 and bending the tongue piece 56 in a state where the

sheets

27, 28, and 30 are joined or not joined outward.

Referring to FIGS. 1 and 7, in this embodiment, as described above, the absorber 29 in the intermediate region 13 is located only in the central region 18 and is not present in the first region 16 and the second region 17. The pet animal 5 tends to dislike that the movement of the hind limb 7 is restricted as compared with a human being. When the relatively stiff absorber 29 is arranged in the movable region of the hind limb 7, the absorber 29 If he is stiff, he / she dislikes moving the hind limb 7 and there is a risk that the amount of activity during walking will decrease. In the present embodiment, the absorber 29 is disposed only in the central region 18 and is not located in the movable region of the hind limb 7, and the movement of the hind limb 7 is hindered and the amount of activity during walking is reduced. Absent. Further, when the absorbent article 10 is worn by a female pet animal, the urinator is located opposite to the central region 18, so that excrement such as urine is reliably absorbed and retained by the absorber 29 in the central region 18. Since the absorber 29 is not arranged in the first and

second areas

16 and 17 where the urineator is not opposed to the first and

second areas

16 and 17, as compared with the case where it is arranged in the entire intermediate area 13. Excellent absorption efficiency.

In addition, when the absorbent article 10 is worn on the pet animal 5, the first high-rigidity region 61 is contracted by the

elastic bodies

43 and 44 fixed so as to be retractable in the longitudinal direction Y in the side edges 14c contracting. The dimension in the vertical direction Y of the low-rigidity region 63 located between the first and second high-rigidity regions 62 is reduced. Therefore, the low rigidity region 63 is a pet animal as shown in FIG. 7 due to the contracting action of the

elastic bodies

43 and 44 and the rigidity difference between the first and second

high rigidity regions

61 and 62 and the low rigidity region 63. The space portion (pocket) 70 is defined between the body of the pet animal 5 and the low-rigidity region 63. Accordingly, when the male pet animal 5 is to be worn, the urinator is positioned opposite to the first area 16 where the absorber 29 does not exist, and excrement such as urine moves to the ventral region 11 side. The excrement can be temporarily accommodated in the space portion 70 to prevent the excretion from leaking to the outside, and a relatively large amount of urine is excreted when the female pet animal 5 wears the excrement. Even when the excrement cannot be absorbed by the absorber 29 in the central region 18, the excrement moved to the ventral region 11 side can be temporarily accommodated in the space portion 70 to prevent leakage to the outside.

In the present embodiment, as shown in FIG. 6, the length dimension Y in the longitudinal direction Y (the dimension between the ventral ribbon elastic body 35 and the absorbent body 29) L3 of the low-rigidity region 63 is the second high height. It is larger than the length dimension W1 of the rigid region 62 in the lateral direction X. As described above, the relatively large length of the low-rigidity region 63 makes the space 70 formed by the low-rigidity region 63 relatively large, and reliably accommodates urine that has moved to the ventral region 11 side. Can do.

Further, the length dimension of the low-rigidity region 63 in the lateral direction X (the dimension between the pair of side elastic bodies 43 adjacent to the vertical axis P in the lateral direction X) W3 is the length dimension of the absorbent body 29 in the lateral direction X. It is larger than W2. Thus, since the length dimension W3 in the lateral direction of the low-rigidity region 63 is larger than the length dimension W2 in the lateral direction X of the absorber 29, a relatively large amount of excrement is excreted, and the absorber 29 Even if excrement flows to the ventral region 11 side without being able to absorb part of the excrement, the length of the low rigidity region 63 in the lateral direction X is large, so that excrement is prevented from leaking from the absorbent article. can do.

Referring to FIG. 8, in the wearing state, the space 47 by the containment flap 46 erected by the contracting action of the elastic element and the space 70 by the low rigidity region 63 communicate with each other, so that a relatively large accommodation space S is formed. Defined. By defining the accommodation space S on the ventral region 11 side, leakage of urine that has moved to the ventral region 11 side is more effective than when only one of the

space portions

47 and 70 is formed. Can be prevented.

In this embodiment, rigidity is provided by arranging the ventral ribbon elastic body 35 in the first high-rigidity region 61. In addition to arranging the ribbon-like elastic body, for example, a plurality of strands Or a string-like elastic body (elastic element) or elastic or inelastic fiber nonwoven fabric, or by embossing / debossing the sheet member by heating and / or pressurization. May be. Moreover, the elastic body arrange | positioned in the ventral region 11 is not restricted to a ribbon-shaped thing, You may arrange | position elastic bodies, such as a strand form or a string form.

For the members constituting the absorbent article 10, unless otherwise specified, in addition to the materials described in the present specification, known materials that are usually used in this kind of field are used without limitation. Can do. Further, terms such as “first” and “second” used in the present specification are merely used to distinguish similar elements, positions, and the like.
