Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvements in pet wearable articles such as disposable diapers for pets and absorbent articles for sanitary use.

[0002]

2. Description of the Related Art Generally, a diaper for a pet has a hole formed at a position corresponding to the tail, and when used (wearing), the tail of the pet is designed to pass through the hole.

In a conventional diaper for pets, in order to prevent leakage from a hole through which a pet's tail passes, for example,
Some have three-dimensional gathers around the holes.

[0004]

However, when a solid gather is provided around the hole, leakage from the hole is reduced, but it is difficult to mount the diaper because the hole itself is small. . That is, it is not easy to grasp the tail of a pet by hand and pass it through the hole, and the pet often dislikes wearing a diaper. In particular, when the pet is attached to a large body (thick tail), the above problems become serious.

The present invention has been made in view of the above situation, and an object thereof is to provide a diaper for pets which is easy to wear. Another object of the present invention is to provide a pet diaper that can be flexibly adapted to pets having different body shapes and physiques and is excellent in fit.

[0006]

In order to achieve the above object, a pet diaper according to a first aspect of the present invention is a pet diaper; a main body portion mounted from the abdomen of the pet to the back; An absorbent body that absorbs pet excrement;
An elongated hole formed at a position corresponding to the tail of the pet of the main body. The elongated hole is formed sufficiently larger than the diameter of the tail of the pet to be attached.

According to the second aspect of the present invention, a water-repellent stretchable member is provided so as to cover a part of the pet's ventral side of the elongated hole.

In the invention according to claim 3, the elastic member may be a non-woven fabric alone, a film alone, a laminated structure of a non-woven fabric and a film, or a foam. Here, as the non-woven fabric simple substance, polyurethane, SI
S (styrene / isoprene / styrene copolymer), SE
A melt blown nonwoven fabric made of a BS (styrene / ethylene / butadiene / styrene copolymer) resin can be used. As a single film, styrene elastomer film such as isoprene or butadiene, or EV
A polyolefin-based elastomer film such as A (ethylene vinyl acetate) can be used. Also,
As the foam, closed cell urethane or the like can be used. The stretchable member preferably has a strength at 100% elongation of 0.5 N / 25 mm or more and a permanent set of 30% or more.

In the invention according to claim 4, the elongated hole is set so as not to reach the absorber.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.
Description will be given with reference to the accompanying drawings. In addition, although the name of the invention in this specification is "diaper", the present invention is widely applicable to a sanitary absorbent article for pets having a tail, etc., in addition to the diaper.

FIG. 1 is a plan view (inside) showing the structure of a pet diaper according to an embodiment of the present invention. FIG. 2 is a plan view (outside) showing the structure of a diaper for pets. Further, FIG. 3 and FIG. 4 respectively show the I-I direction and the II- direction of FIG.
It is sectional drawing of II direction. The pet diaper according to the present embodiment includes a main body formed in an hourglass shape whose upper and lower ends are spread in the width direction; and an absorber 14 that absorbs pet excrement in the main body. As shown in FIGS. 3 and 4, the absorber 14 is disposed between the liquid-permeable top sheet 10 and the liquid-impermeable back sheet 12. The absorber 14 contains a super absorbent polymer and pulp pieces, and is surrounded by a water absorbing paper 11 such as a tissue. A breathable waterproof film 13 is provided inside the back sheet 12.

As the water absorbent paper 11, tissue, hydrophilic non-woven fabric, spun bond non-woven fabric, through air non-woven fabric, water jet non-woven fabric, etc. can be used. If the absorbent paper 11 is too coarse, the absorbent body 14 will leak the superabsorbent polymer and pulp, so a relatively fine material is used.

On the top sheet 10, an absorber 14 is provided.
Solid gathers 24 extending in the longitudinal direction of the main body are provided on both left and right sides of the main body. A leg gather 26 is formed at a position corresponding to the leg opening. Adhesive tapes 16 are provided on both left and right sides of the ventral end of the main body. Corresponding to this, an adhesive region 18 that engages with or adheres to the adhesive tape 16 is formed at the back end of the main body. The adhesive region 18 is formed on the outer surface of the backsheet 12. As the adhesive tape 16, for example, a hook member of a mechanical fastener can be used. In this case, a loop member of a mechanical fastener is used for the bonding area 18.

The absorber 14 is arranged on the ventral side of the main body,
It is not placed near the back edge. An elongated hole 20 is formed on the back side of the body for allowing the pet's tail to pass through. The long hole 20 is formed to be sufficiently larger than the diameter of the tail of the pet to be attached. The long hole 20 also serves as the absorber 1.
It is formed so as not to reach 4 and it is possible to prevent excrement such as urine absorbed and held in the absorbent body 14 from leaking out from the elongated hole 20. A sheet-shaped elastic member 22 is provided in the ventral region of the elongated hole 20.

The elastic member 22 may be a nonwoven fabric alone, a film alone, a laminated structure of a nonwoven fabric and a film, or a foam. Here, as the non-woven fabric simple substance, polyurethane, SIS (styrene / isoprene /
Styrene copolymer), SEBS (styrene / ethylene /
A meltblown nonwoven fabric made of a butadiene / styrene copolymer resin can be used. As the film itself, a styrene elastomer film such as isoprene or butadiene or a polyolefin elastomer film such as EVA (ethylene vinyl acetate) can be used. Further, as the foam, closed cell urethane or the like can be used. The elastic member is
It is preferable that the strength at 100% elongation is 0.5 N / 25 mm or more and the permanent set is 30% or more.

FIG. 5 shows a bonded state (area) of the elastic member 22. The stretchable member 22 of the present embodiment is formed in a rectangular shape, and its three sides are fixed to the main body in a U-shape. The back end of the elastic member 22 reaches a position beyond the center of the elongated hole 20. The region where the stretchable member 22 and the elongated hole 20 overlap each other is the permissible range of variation in the tail position of the pet. That is, the long hole 20
Even if the position of the pet's tail fluctuates within the range covered by the stretchable member 22, the stretchability of the stretchable member 22 can be used.

Although not shown in FIG. 5, the water-absorbent paper 1
1 extends slightly inward from the edge of the slot 20. This makes it possible to instantaneously absorb the discharged matter, which tends to leak from the anus of the pet or the like, to the outside by the inner edge portion of the elongated hole 20, and to suppress the force of the leak.

Next, a method of using the diaper for pet according to this embodiment will be described with reference to FIG. First, the tail 32 of the pet is passed through the long hole 20, and the abdomen side (absorbent body 14 side) of the main body is applied to the abdomen of the pet. Next, put the back side of the main body part on the back of the pet, and attach the adhesive tape 1 at the abdominal end
6 is adhesively fixed to the adhesive region 18 at the back end.
In this embodiment, even if the tail 32 of the pet is thicker than the penetrating region of the elongated hole (the portion not covered with the elastic member 22), the tail 32 has the elastic member 2 as shown in FIG.
It acts so as to compress 2 and a sufficient space can be secured. In addition, the pet has a tail 32 after wearing the diaper.
Even when is moved, the elastic member 22 can absorb the movement. That is, the tail 32 of the pet and the ventral side of the slot 20 are always fitted, and the tail 32 and the slot 2
Excrete does not leak out from the gap with 0.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and the design can be appropriately changed within the scope of the technical idea shown in the claims. Needless to say.

[0020]

As described above, claim 1 of the present application
According to the invention described in (1), the main body has the elongated hole that is sufficiently larger than the diameter of the tail of the pet at a position corresponding to the tail of the pet. There is also an advantage that it can be applied to pets having different body shapes and sizes.

According to the second aspect of the invention, since the water-repellent elastic member is provided so as to cover a part of the ventral side of the long hole, even if the pet moves its tail, the tail is moved. It is possible to prevent a gap from being formed between the slot and the ventral side of the slot. As a result, it is possible to prevent leakage of excrement from around the anus of the pet. When the non-woven fabric alone, the single film, the laminated structure of the non-woven fabric and the film, or the foam is used as the elastic member, the leak prevention effect is further improved.

According to the invention as set forth in claim 4, since the elongated holes are arranged so as not to reach the absorber, excrements such as urine absorbed and retained in the absorber leak out from the elongated holes. Can be prevented.
