2. Description of the Related Art Various simple toilets and waste disposal tools using a coagulant such as a water-absorbing polymer have been developed.
The simplest structures include those in which a powdery coagulant is sealed in a waterproof bag, and those using coagulated paper together with the waterproof bag. Among them, those using coagulated paper have higher coagulation ability than those using powdered coagulant, but on the other hand, coagulated paper and bags must be stored separately, There was such an inconvenience that coagulated paper had to be spread inside the bag. Recently, to solve these problems, coagulation paper has been developed outside of the bag and turned over when used.However, the use of coagulation paper remains troublesome, and the coagulation paper must be manually attached. Therefore, it is difficult to further reduce costs. Since the Great Hanshin Earthquake, public and private sectors have been preparing for disaster prevention,
In order for emergency supplies to reach the entire population, more accessible products must be offered at more affordable prices. In addition, garbage and landfill garbage from homes and restaurants contain a large amount of various juices and oils that cause odors, but conventional garbage bags do not have the function of absorbing and coagulating these juices. Therefore, when this is damaged by a crow or a cat, garbage and containers to which the garbage is attached are scattered together with the meat juice, and an unpleasant odor spreads to the surroundings on a daily basis. In order to prevent this, garbage bags are covered with nets or double-bottomed garbage bags are used. However, the effect has not been recognized as almost completely. is there.

[0003]

The problem to be solved by the present invention is not only an emergency toilet at the time of a disaster or a simple toilet for nursing care and recreation but also a daily garbage disposal tool such as a home or a restaurant. In addition, it is possible to treat not only human and animal excrement, but also any liquid that is unpleasant to humans such as garbage and oil. The purpose is to provide at a low cost, and therefore, to streamline the attachment of the coagulant or coagulated paper, which has conventionally been performed manually, and to reduce the manufacturing cost of the waste disposal bag as much as possible.
