Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a water-dispersible waste excrement disposal bag for pets.

B. Conventional technology The pet boom of dogs, cats, etc. is becoming a big problem, especially in urban areas, because it is difficult to dispose of the excretion of these pets.

Traditionally, local governments have requested pet enthusiasts to bring bags such as polyolefin and scoops to the pets for a walk, put the generated excrement in it and take it home, and bury it in the garden for disposal. And gradually spreading.

However, such methods are becoming difficult in urban areas where there is little soil to handle the kind of excretions that are brought back.

In addition, it is also possible to remove the excrement that has been brought back in a bag such as polyolefin from the bag and treat it in a flush toilet.However, in this method, the hands are stained or the excrement is removed. The same problem with bag handling occurred,
It is far from a fundamental solution.

On the other hand, if the bag itself for putting the kind of excrement that has been generated into it and bringing it back can be made water-dispersible, the excrement that has been brought back can be treated in the flush toilet together with the bag, which is a good solution to this problem.

However, a method of simply putting excrement types into bags such as toilet paper and taking them home at home instead of bags made of polyolefins, etc., has a major disadvantage that such paper bags have no odor barrier property. Problems arise.

C. Problems to be Solved by the Invention The present invention is to provide a waste disposal bag for pets which does not have the above problems.

D. Means for Solving the Problems The inventors of the present invention have made diligent studies to solve the above-mentioned problems, and as a result, have been constituted by a water-dispersible paper (A) and a film composed of a water-soluble or water-dispersible polymer. We have found a water-dispersible treatment bag that can be used to complete the present invention.

That is, when the above treatment bag is used, not only can it be treated in a flush toilet, but also the problem of odor barrier property can be solved.

The treatment bag of the present invention is a bag using a material composed of a water-dispersible paper (A) and a film (B) made of a water-soluble or water-dispersible polymer.

As an example of the present invention, FIG. 1 shows a sketch of a pet's excrement disposal bag and a sectional view taken along the arrow.

The water-dispersible paper (A) is a paper produced by significantly reducing the hydrophobic sizing agent and using the hydrophilic sizing agent, and having a property of disintegrating and dispersing by the stirring action of the water stream after absorbing water and swelling. is there. The film (B) made of a water-soluble or water-dispersible polymer is a polyvinyl alcohol resin, starch, carboxymethyl cellulose, methyl cellulose,
A water-soluble or water-dispersible film made of a water-soluble or water-dispersible polymer such as polyethylene oxide, water-soluble polyester, water-soluble nylon, polyacrylamide, polyacrylic acid and salts thereof or esters thereof.

The method of laminating the water-dispersible paper (A) and the film (B) made of a water-soluble or water-dispersible polymer is a method of extruding and laminating the polymer on the water-dispersible paper (A).
A method in which an appropriate amount of water, hydrous alcohol, or a water-soluble or water-dispersible adhesive is applied to the water-dispersible paper (A), the above-mentioned film (B) is pressure-bonded, and heated if necessary. But it's okay.

The surface of the film (B) to be laminated on the water-dispersible paper (A) may be one side or both sides.

Furthermore, in order to temporarily protect the surface of the film (B) from moisture, a water repellent such as silicone may be applied to the surface.

E. Examples Hereinafter, the present invention will be described more specifically with reference to Examples, but the present invention is not limited to the following Examples.

Example An alkali catalyst was added to a methanol solution of polyvinyl acetate to saponify 60 mol% of the vinyl acetate portion and then dried to obtain a polyvinyl alcohol resin having a polymerization degree of 400.

The obtained polyvinyl alcohol-based resin has a die width
It is supplied to the feed port of a single screw extruder with a screw diameter of 40 mm equipped with a 360 mm T-die, and the screw rotation speed is 100 ° C in the first zone, 160 ° C in the second zone, 200 ° C in the third zone, and 200 ° C in the die. It was extruded at 80 rpm and melt-extruded and laminated on a paper having water dispersibility prepared in advance at a speed of 30 m / min and a resin thickness of 40 μ.

After applying a silicone-based water repellent to the surface of the resin portion of the obtained laminated paper, two sheets of the obtained laminated paper are heat-sealed with each resin portion being the inside,
A bag-like material having a length of 25 cm was prepared. The bag thus produced had a good odor barrier property and could be easily washed off in a flush toilet.

F. Effects of the Invention As described above, the water-dispersible pet waste disposal bag of the present invention is convenient in that the excrement can be disposed of in the flush toilet without soiling the hands. Is extremely useful.
