Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a defecation storage bag. More specifically, the present invention relates to a disposable defecation bag used by people in an environment where a flush toilet cannot be used at all in the event of a major disaster such as an earthquake, a large fire, a storm, a flood, or a landslide.

[0002]

2. Description of the Related Art Conventionally, large disasters such as large earthquakes, large fires, storms, and landslides have occurred over a wide area, and electricity,
When various facilities such as gas and water supply are damaged and these facilities become unusable, the flush toilets that are normally used cannot be used at all in the densely populated areas of large cities and areas with high-rise buildings. As for stools, there was no choice but to use temporary toilets, prefabricated toilets, toilets with filth storage packs, and so on. As examples of these, it is proposed to use a temporary toilet in Japanese Examined Patent Publication No. 58-47534, and to use a waste container, bag, etc. in Japanese Laid-Open Patent Publications 63-63456 and 1-160550.

[0003]

[Problems to be Solved by the Invention] However, in the case of a temporary toilet, since it is a storage type, there is no consideration in terms of hygiene such as a bad odor, and there is a problem. If it is high, the processing capacity will be insufficient. In addition, it is difficult to dispose of when the sewage system to which excess liquid is discharged is damaged.

Further, for example, the waste bags and waste containers proposed in JP-A-63-63456 and JP-A-1-160550 are convenient because they can be dumped in a flush toilet, but in the event of a disaster sewer facilities There is a problem if the flush toilet is damaged and cannot be used.

[0005]

[Means for Solving the Problems] Under these circumstances, the present inventors have conducted extensive studies to solve the above problems, and as a result, by using a special defecation bag, the conventional problems The inventors have found that all the points can be solved at once and completed the present invention. That is, the present invention is a bag containing a water absorbing agent, a solidifying agent,
It has a composition consisting of a deodorant and a bactericide, has an openable and closable structure at the upper end, has a shape that tapers from the top or middle of the bag to the bottom, and the material of the bag is A defecation bag characterized by being made of a biodegradable polymer. More specifically, it is easy to treat feces (or defecation, excrement, feces), and it is hygienic without any offensive odor after treatment of feces, and can be temporarily stored until disaster recovery. It is a disposable defecation bag that can be landfilled in the ground without being disposed of in sewage facilities, is biodegradable in the ground, and does not deteriorate the environment.

The defecation bag of the present invention is made of a film that does not allow liquids, solids and the like to pass through. As the material of the film, any resin that can be formed into a film and, when formed into a film, must be a resin that does not allow the passage of manure and a polymer that is biodegradable after being buried in the ground is used. It is possible.

Specific examples of the film material used in the defecation bag of the present invention include natural polymers such as cellulose, chitosan and pullulan, and synthetic polymers such as polycaprolactone, fatty acid polyester, polyamino acid and polyglycolide. , Polybutyric acid, polyvinyl alcohol, copolymers of carbon dioxide and ethylene oxide, copolyesters made by microorganisms (copolymers of propionic acid and valeric acid), mixtures of ethylene-acrylic acid copolymers and starch, olefin resins Mixtures of starch, poly (3-hydroxybutyrate) and the like.

The size of the defecation bag in the present invention is not limited in any way, and a size convenient for use, carrying, storage, etc. is adopted. Generally, the length of the bag is 60 to 90 cm, and the width (the upper end of the bag is 60 to 90 cm, the bottom of the bag is 20 to 40 cm).
