[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable toilet bowl, and more particularly, to a paper disposable toilet bowl which can be landfilled or incinerated.

[0002]

2. Description of the Related Art Conventionally, toilets and so-called "portable toilets" are used in hospitals and nursing homes for patients who have difficulty walking and for those who enter the park. After using these toilets,
Although they were manually cleaned, the discomfort of the work was inevitable. As a countermeasure, portable polyethylene bags
It can be placed inside the toilet, and after use, only the polyethylene bag can be taken out and disposed of.Also, as a countermeasure against odor, fluff pulp can be impregnated with a deodorant and placed in a granular form. Department has been done.

[0003]

However, since polyethylene bags do not corrode, they are not suitable for landfill treatment, and there is also a problem that, during incineration treatment, waste containing considerable moisture lowers the combustion efficiency. Therefore, there has been a demand for the development of a paper disposable toilet bowl suitable for incineration. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a corrugated paper toilet bowl which is waterproof, can prevent oozing of dirt, and can be easily sealed.

[0004]

In order to solve the above-mentioned problems, a toilet bowl according to the present invention comprises an unbleached kraft paper impregnated with a melamine resin or an euramine resin and at least one surface of which contains an acrylic latex as a main component. Heat-sealing one end of a pleated tubular body having a waterproof adhesive applied to the inner surface with the waterproofing agent applied to the inside and a body sticking portion attached with a water-resistant adhesive, and bent twice, The bent portion is stuck on the bag wall to close the end to form a bag, and the center of the bag is shifted from the other edge by an appropriate distance exceeding the distance corresponding to the depth of the fold. A folding line is provided over the entire width of the bag body, and a portion of the one wall of the bag body near the opening end is folded back toward the closed end along the folding line to cover the opening end and cover the opening. Affix a flange on a square paperboard with the center punched into a square on the periphery. A fold groove is formed along a fold line which is a fold line before the opening end portion is exposed on the periphery of the opening portion on the edge of the opening portion, and the front and rear two walls of the bag body of the flange. And a continuous U-shaped adhesive band is provided on at least a portion including the bent groove on the side connected to the two folds adjacent to the wall.

[0005] As a waterproofing agent to be applied to unbleached kraft paper impregnated with a melamine resin or an euramine resin, 5 to 20 parts by weight of a wax-based emulsion solid content is blended with 100 parts by weight of an acrylic latex solid content. The use of the aqueous emulsion makes it possible to impart water repellency to the base paper in addition to waterproofness, and it is possible to more reliably prevent exudation of dirt.

[0006] The U-shaped adhesive band provided on the flange of the square paperboard attached to the open end of the bag body includes:
A double-sided pressure-sensitive adhesive tape whose surface is covered with release paper may be attached to the portion. As a countermeasure against odor, fluff pulp may be impregnated with a deodorant and made into granules and placed in a bag.

[0007]

[Function] The toilet bowl according to the present invention is made of unbleached kraft paper impregnated with melamine resin or Euramine resin and coated on at least one surface with a waterproofing agent mainly composed of acrylic latex. Since the body sticking part is attached with a waterproof adhesive, and the bottom end is closed by heat sealing,
The exudation of filth can be prevented. On the other hand, when the above-mentioned materials are buried in the soil, they corrode in a short time. After use, the toilet bowl of the present invention can be easily sealed by bending the flange of the paperboard along the folding groove and sticking the opposing faces together with a U-shaped adhesive band.
