The width of the obverse sheet 4 is made lager than those of the other materials 2,3 and the right and left edges are bent down and the bent parts are layered on the reverse-side of the water-proofing sheet 2 or inserted between the water-proofing sheet 2 and the internal absorbing material 3. The obverse sheet 4 and the water-proofing sheet 2 are fixed to each other at the layered parts. Further, the front and back ends of the water-proofing sheet 2 and the obverse sheet 4 are fixed to each other.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a back-sealed pet sheet in which urine water does not stay on the surface.

[0002]

2. Description of the Related Art A pet bed sheet for dogs having a three-layer structure in which a water absorbent material such as a polymer is inserted between a lower waterproof sheet and a water-absorbent front sheet is generally used as shown in FIGS. The width of the waterproof sheet 10 is made larger than that of the front sheet 11 and the water absorbent material 12 in the middle, and the left and right sides of the protruding waterproof sheet 10 are bent upward so as to be interposed between the front sheet 11 and the water absorbent material 12. The waterproof sheet 10 and the left and right overlapping portions 14 of the front sheet 11 are thermocompression-bonded to each other to seal the longitudinal direction into a band 13
On the other hand, the front and rear portions of the waterproof sheet 10 and the front sheet 11 are formed to be longer than the intermediate water-absorbing material 12, and their protruding portions are fused and sealed to each other.

[0003]

According to the above-mentioned prior art, since the bent portion 10a of the waterproof sheet 10 is located on the upper surface of the water absorbent material 12 on the left and right sides of the seal 13 in the longitudinal direction, the water leaks to this portion. Poor permeability because urine water once stays and does not fall onto the water absorbent immediately, and it is not hygienic because the urine odor may diffuse and the urine water may touch the pet's feet and pollute the room. As a result, the crimping marks of the seal 13 are exposed on both sides of the length of the sheet, so that the appearance is not good and the feel is not good.

The present invention has been made in view of the above-mentioned conventional circumstances, and urine water does not stay on the surface of the sheets and has good permeability, so that the function of the water absorbing material is sufficiently exerted.
It is an object of the present invention to provide a pet sheet with a good appearance because there is no possibility that the scent will diffuse and the inside of the room will be contaminated even if the pet moves, and that no crimp marks of the seal will appear in the longitudinal direction of the sheet surface.

[0005]

In order to achieve the above object, the present invention has a three-layer rectangular pet having a water-absorbing front sheet superposed with an intermediate water-absorbing material on the top surface of the waterproof sheet. In the sheets, the waterproof sheet and the intermediate water-absorbing material are formed to have almost the same width, and the left and right sides of the front sheet having a width larger than these are bent downward, and the bent portions are overlapped with the back surface of the waterproof sheet or the waterproof sheet is formed. And the intermediate water-absorbing material, and the front sheet and the waterproof sheet are fixed to each other at the overlapping portion on the back surface. It is intended to obtain a back-sealed pet sheet characterized by sealing a water absorbent material.

[0006]

Since only the water-absorbent surface sheet is present on the upper surface of the water-absorbent material, the urine water of pets first penetrates into the water-absorbent material from any position on the surface sheet. The urine water that has entered the water absorbent diffuses laterally, and the waterproof sheet prevents the water from leaking downward. Therefore, if the used sheets are discarded as they are, the urine water is treated without traces.

[0007]

EXAMPLE FIG. 1 shows a pet sheet 1 of the present invention, which has a rectangular shape with a vertical length of about 45 cm and a width of about 30 cm, and has a seal portion of about 2 cm at the front and rear, This is visible from the surface, but there are no seals on the left and right.

FIG. 2 is a cross section of the pet sheet 1, in which a waterproof sheet 2 made of a polyethylene film is located at the lowermost portion, and an intermediate water-absorbing material 3 having an equal width is superposed on the upper surface thereof. The intermediate water absorbing material 3 is obtained by stacking two polymer sheets 3a and 3b containing a polymer on a base paper and embossing the whole. Incidentally, it goes without saying that the water-absorbing material 3 can exert a further water-absorbing effect by polymerizing another water-absorbing sheet with the above-mentioned polymer sheet.

On the upper surface of the intermediate water-absorbing material 3, a water-absorbing front sheet 4 made of a non-woven fabric having a width of about 4 cm larger than the waterproof sheet 2 and the water-absorbing material 3 is polymerized, and both sides are evenly (2
(about cm) Bending downward and superposing the bent portion on the back surface of the waterproof sheet 2. Then, the fused front sheet 4 and the overlapping portion of the waterproof sheet 2 are heat-sealed to form the fusion-bonded portion 5.

FIG. 3 shows a modification of FIG. 2, in which the folded portion of the front sheet 4 folded downward is interposed between the intermediate water-absorbing material 3 and the waterproof sheet 2, and the folded portion and the waterproof sheet 2 are polymerized. The parts are heat-sealed to form the fusion-bonded part 5.

FIG. 4 is a vertical cross section of the pet sheet 1. The waterproof sheet 2 and the front sheet 4 are formed such that the front and rear portions thereof are longer than the water-absorbent material 3 by about 2 cm, and the portions are heat-sealed. The fused portion 6 is formed. That is, both sides in the longitudinal direction of the intermediate water-absorbing material 3 are fixed by the bent portions of the front sheet 4 and the fusion-bonded portions 5 on the back surface, and the front and rear ends are fixed by the fusion-bonded portions 6.

In addition to heat sealing, for example, a hot melt adhesive or an adhesive is used for the overlapping portion of the folded front sheet 4 and the waterproof sheet 2 as shown in FIGS.
May be Similarly, the front and rear ends of the waterproof sheet 2 and the front sheet 4 are adhered to each other by using an adhesive or an adhesive as shown in FIG.
Further, the sheets can be fixed to each other by the combination of the fusion portion 5 and the adhesion portion 6a, or the combination of the adhesion portion 5a and the fusion portion 6, but these are also the free working range of the present invention. Belong to.

[0013]

The present invention as described above has the following unique effects. (1) There is no waterproof sheet on the left and right of the upper surface of the sheet, and since only the water-absorbent surface sheet exists, pet urine water does not directly permeate the water-absorbing material from any part of the surface sheet and stay on the surface. It has good absorption efficiency and is hygienic because it does not emit urine odors or stick to pet's feet, and the waterproof sheet on the bottom surface prevents leakage of urine water and keeps the surrounding area clean. Be done. (2) Since the fused and bonded portions on both sides in the longitudinal direction are located on the back surface of the sheet, there are no pressure marks or adhesion marks on the surface,
The appearance is good and it is treated well without getting tired. (3) Since the pet's feet do not come into direct contact with the fixed portion by providing the vertical fixing portion on the back surface of the sheet, the portion is not peeled off or cut and damaged, and rather the fixed portion is pressed from above. Since it becomes a shape, the width of the fixed part can be narrowed, and there is an actual benefit that the sheet can be easily manufactured. (4) Both sides in the vertical direction of the intermediate water-absorbing material are tightly fixed by the bent portions of the front sheet and the fixed portions on the back surface, and the front and rear ends in the horizontal direction are also fixed by the fixed portions, so that even if the pet moves. The water absorbent inside does not move,
Therefore, since it always functions correctly, urine water can be treated efficiently.
