JPH09131143A - Excreta-absorbing sheet - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a sheet having strong odor absorbing action and capable of laying on a excreta-bed of a pet such as a dog, a bed for the aged, a portable stool, etc., and being used for a long time. SOLUTION: This excreta-absorbing sheet is prepared by laying a porous sheet 1 on a working table with a fusion side of a hot melt film 2 upward, putting on the mixture 4 of a water absorbing resin (e.g. an acrylic water absorbing resin) with a deodorant (e.g. active carbon) in a surrounded part with the hot melt film 2, laying another porous sheet 1 on the mixture with its hot melt film side downward and heat-sealing the pair of the porous sheets 1, 1 through hot melt films 2, 2 on both sides. As the porous sheet, e.g. a polyester fiber knit can be used.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manure absorbing sheet which is laid on the toilet bed of pets such as dogs and cats, or on the beds of elderly people, infants and sick people and in portable toilets.

[0002]

2. Description of the Related Art Newspapers, non-woven fabrics as sheets for pets, etc. are conventionally laid on the toilet floor of pets such as dogs and cats.

[0003]

However, newspaper has a low water absorption, and even a sheet for pets has a low water absorption rate of about 10 to 300 ml per sheet, and a pet with a large amount of urine is used for the pet. There is a problem in that the sheets need to be changed at least twice a day, and the water once absorbed by the pet sheets easily separates and remains on the toilet bed. Further, the pet sheets have a low deodorizing ability, and there is a problem that a bad odor is emitted to the surroundings.

[0004]

Means for Solving the Problems As a means for solving the above conventional problems, the present invention provides a mixture of a water absorbent resin and a deodorant inside a bag-like body (5) made of a porous sheet (1). (Four)
To provide a manure absorption sheet (6) containing
It is desirable that an antibacterial agent is further added to the mixture (4).

[0005]

1 to 3 show an embodiment of the present invention. FIG. 1 shows a porous sheet (1), which is a polyester fiber, polyethylene fiber, polypropylene fiber, polyamide fiber, acrylic fiber, urethane fiber, polyvinyl chloride fiber, polyvinylidene chloride. Knitted or non-woven fabrics of synthetic fibers and / or natural fibers such as fibers, acetate fibers, pulp, cotton, wool, palm fibers, hemp fibers, polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyurethane,
A foam sheet or the like having an open cell structure of a plastic such as a melamine resin, and a hot melt film (2) such as polyethylene, a low melting point polyamide, a low melting point polyester or the like is formed in a lattice on one surface of the porous sheet (1). It is welded.

[0006] One piece of the above-mentioned porous sheet (1) is placed on a workbench with the hot melt film (2) welding side up, and water is absorbed in a compartment (3) surrounded by the hot melt film (2). A predetermined amount of a mixture of a resin and a deodorant (4) is placed, and then a hot-melt film (2) another porous sheet (1) is placed with the welding side down, and the pair of upper and lower porous sheets is placed. Heat seal (1,1) through both hot melt films (2,2). Thus, as shown in FIG. 2, in the case of the present embodiment, the excrement absorption sheet (6) containing the mixture (4) in the bag-shaped body (5) of 5 × 4 = 20 is manufactured. .

Examples of the water-absorbent resin include acrylic water-absorbent resin, starch-acrylic water-absorbent resin, starch water-absorbent resin, urethane water-absorbent resin, etc.
It is a water-absorbent resin of and has a water absorption capacity of 20 to 70 g in physiological saline.

Silica gel, zeolite, activated carbon, cyclodextrin, chlorophyll and the like are used as the deodorant, and two or more kinds of the deodorants may be mixed.

In addition to the water absorbent resin and the deodorant, an antibacterial agent may be added if desired, and a dye, a fragrance, etc. may be added if desired.

The inner volume of the bag-like body (5) of the manure-absorbing sheet (6) is determined by the water-absorption expansion volume of the water-absorbent resin contained in the mixture (4) contained in the bag-like body (5). Set in consideration. For example, when a water absorbent resin having a urine absorbing capacity of 50 g per 1 g is contained in the bag-like body (5), the inner volume of the bag-like body (5) is set to about 75 ml. In the case of the manure absorption sheet (6) of the present embodiment, since the bag-like bodies (5) are arranged in 5 × 4 = 20 pieces, the urine absorption capacity per sheet of the manure absorption sheet (6) is 50g x 20 pieces = 1kg, assuming that the urine specific gravity is 1, the urine absorption capacity per sheet of the feces and urine absorption sheet (6) is 1000ml.
Becomes

Since the urine output of an adult cat is about 100 ml per day, the feces and urine absorption sheet (6) can be used for about 10 days until it reaches saturation of urine absorption.
As shown in (4), the water absorbent resin of the manure absorbing sheet (6) absorbs and swells by urine, and each bag-like body (5) swells.

[0012]

The feces and urine absorbing sheet of the present invention has a very large urine absorption amount and does not release water to the outside, so that it can be used for a long period of time and has a large odor absorbing action and does not emit a bad odor to the surroundings.
