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 for disasters. More specifically, in the event of a major disaster such as an earthquake, a large fire, a storm, a flood, a landslide, etc., various facilities such as electricity, gas, and water are damaged in a wide area, and the flush toilet cannot be used at all. In regard to the above, it relates to a defecation storage bag used by people.

[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,
If various facilities such as gas and water supply are damaged and these facilities become unavailable, the flush toilets that are normally used cannot be used at all, so there is no choice but to go to a vacant lot or a construction site. Or, I used to use a simple storage tank type toilet that is used at temporary venues for entertainment.

[0003]

[Problems to be Solved by the Invention] However, when defecation is performed in an empty space as described above, it is necessary to bury it in the ground for environmental hygiene.
There was a limit to securing an appropriate site. Further, in the case of the simple storage toilet type toilet as described above, since the capacity is small, there is a problem that the processing capacity becomes insufficient if the frequency of use is high. Also, when the toilets are full of vacuum, it is necessary to discharge them with a vacuum car, but it was not easy to get into the disaster area. Moreover, when the number of simple toilets installed is large, a wide and appropriate installation place is required, and there are problems such as an increase in equipment costs. In addition, it is difficult to secure a power source in a disaster area even for mechanical treatment of defecation (drying, crushing, etc.), and when incinerating a large number of people in a disaster area, transportation to an incinerator is hygienic. There were problems above, and it was more difficult than the capacity of the incinerator.

On the other hand, a large number of various temporary toilets, disposable toilets, outdoor toilets, simple toilets, portable toilets, etc. have been proposed for various purposes. However, if these proposals are used as toilets in the event of a disaster, there will be some problems. For example, the portable assembled toilet proposed in Japanese Patent Laid-Open No. 3-242126 uses an opaque deep-bottom bag-like body, and this bag-like body can be normally folded into a small square for miniaturization, making it portable. It is convenient, but after being used as a stool in the event of a disaster, it is not processed at all, which is not preferable for hygiene and mass storage. Further, the toilet bowl proposed in Japanese Patent Laid-Open No. Sho 60-185528 is folded when not in use, sealed after use, convenient to carry and store, and urine spills due to the coagulant added to the absorbent. Although it is proposed to prevent hygiene and hygiene, the contact between the manure (or defecation, feces, human waste) and the coagulant is insufficient, the solidification is not complete, it is shaken in the bag, and it is not convenient to carry. Due to the generation of malodorous gas, the bag expands due to the microorganisms growing from the excrement in the bag, and in some cases, the bag is damaged, which is a sanitary problem. The sealable waste toilet bowl proposed in JP-A-58-143729 is folded when not in use and can be made into a box when used, making it convenient to carry, and a disinfectant can be attached to the toilet bowl. Since it can be sealed,
Although it has been proposed that the microorganisms in the excrement can be sterilized, the contact of the disinfectant with the excrement is insufficient, and the bag is inflated due to the generation of gas after sealing, and the problem such as breakage and transportation due to the fluidity of excrement, There are problems with storage and the toilet itself is bulky, and there are problems with storage and transportation.

[0005]

[Means for Solving the Problems] Under these circumstances, the present inventors have conducted extensive studies to solve the problems, and as a result, by using a special defecation storage bag for disasters, The inventors have found that the conventional problems can be solved all at once, and completed the present invention. That is, the present invention has a band-shaped adhesive applying part on the upper peripheral edge of the inner surface or the outer surface of the bag, is provided with a degassing thread at the time of sealing, has a taper toward the bottom of the bag, and has a water absorbing agent inside. A defecation storage bag comprising a solidifying agent, a deodorant and a bactericide. More specifically, the treatment of manure (or defecation, human waste, feces) is easy, no odor is generated after the treatment of manure, and it can be temporarily stored, stored in large quantities and transported until the time of disaster recovery. It is a disposable defecation storage bag that can be incinerated.

The defecation storage bag of the present invention is made of a film that does not allow liquids, solids, etc. to pass through. As a material of the film, a resin that can be formed into a film and, when formed into a film, does not allow the excrement of manure to pass through is suitable, and any resin that satisfies this condition can be used. Specific examples of film materials include polyethylene, polypropylene,
There are vinyl chloride resin, vinyl acetate resin, nylon resin, polyester resin, acrylic resin, etc., but polyethylene or polypropylene film that does not generate harmful gas when incinerating which is one of the objects of the present invention is used. . The size of the defecation storage bag in the present invention is not limited in any way, and a size convenient for use, carrying and the like is adopted. Generally, the length is 60 to 90 cm, the width (upper part of the bag) 60 to 90 cm, and the width (lower part of the bag) 20 to 40 cm.

The shape of the defecation storage bag in the present invention has a taper toward the bottom of the bag as shown in FIG. 1, for example. The manure that has fallen due to this taper replaces the mixture of the absorbent, solidifying agent, waterproofing agent, and bactericide existing at the bottom with the upper and lower parts, and in the process, the manure mixes well with each component of these mixtures. Can achieve the intended purpose of. The degree of taper is not particularly limited, but the cross-sectional area of the lower part of the bag is 5 to 50 against the cross-sectional area of 100 at the top of the bag.
Is.

The bag of the present invention is provided with a band-shaped adhesive or pressure-sensitive adhesive application portion on the upper peripheral edge of the inner surface or the outer surface (FIG. 3). This band-shaped adhesive application part is usually covered with a protective paper (release paper). After using it on the toilet, peel off this protective paper to bring the adhesive glued surfaces into close contact with each other and press it by hand. The bag can be completely sealed.

A degassing structure is provided at an arbitrary position on the bottom, side surface or upper portion of the bag of the present invention. This degassing structure does not allow the solidified manure and the like in the bag to pass through and out of the bag, but the temperature inside the bag rises and the bag expands, gas is generated, and so on. When the inside becomes positive pressure, only the gas passes through this structure and is released to the outside of the bag, and it is possible to prevent the bag from bursting due to the internal pressure.

As an example of a concrete degassing structure, one having a thread structure in which a thread penetrates from the inside of the bag to a part of the seal portion of the bag, as disclosed in Japanese Patent Laid-Open No. 62-287852.

In the case of a structure having a degassing thread on the bottom, side surface or upper surface of the bag, the thread penetrates from the inside to the outside of the bag at the sealing portion of the bag (FIG. 2). Although solidified manure in the bag does not pass through this structure, it does not go out, but if the temperature inside the bag rises, the bag expands, gas is generated, and the inside of the bag becomes positive pressure. Only the gas passes through this thread structure and is released to the outside of the bag to prevent the bag from bursting due to pressure. The yarn of this yarn structure may be any spun yarn produced by any method, and the material of the yarn may be natural fiber, synthetic fiber or semi-synthetic fiber. Considering this, heat-resistant fibrin-based natural fibers are preferable. The diameter of the yarn is 0.01 to 2 mm, preferably 0.3 to 0.5 mm. The method of forming this thread structure is not particularly limited, and for example, it can be formed by sandwiching a cotton thread between two thermoplastic resin films and fusing the thermoplastic resin films. In addition, a simple fastener can be attached to the defecation storage bag of the present invention for storing and storing the powder described later (see FIGS. 3 and 6).
