Description

  The present invention relates to a disaster toilet used when water or electricity cannot be used at the time of a disaster or when a toilet bowl itself cannot be used, or in a place where there is no toilet (in a passenger car or outdoors).

  If water supply or electricity stops when a natural disaster occurs, the flush toilet cannot be used. The situation is the same at shelters. In disaster situations, toilets that are used under such circumstances generally use an inner bag that does not allow manure and an outer bag that covers the inner bag to be installed in a toilet (including those assembled for emergency use). It is.

  The toilet at the time of disaster will be described with reference to FIG. FIG. 1 shows a box-shaped toilet 10 assembled in an emergency, not a general toilet. The toilet 10 includes a box-shaped main body 11 having an open upper surface, and a toilet seat portion 12 that supports the back of the thigh of the toilet user at the opened edge of the main body 11. An internal space 13 is formed below the toilet seat 12.

  The toilet user uses a treatment bag comprising an outer bag 20 having an opening larger than the outer periphery of the toilet seat 12 and an opaque inner bag 30 positioned inside the outer bag 20 as the inner space 13. Set against. Specifically, the opening edge of the outer bag 20 is placed on the toilet seat 12, and the bottom of the outer bag 20 is placed in the inner space 13. The inner bag 30 is accommodated in the inner space 13 inside the outer bag 20.

  The toilet user sits on the toilet seat 12 covered with the outer bag 20 and adds to the inside of the inner bag 30. When the application is completed, the opening of the inner bag 30 is closed with a string. Subsequently, the outer bag 20 is removed from the toilet seat portion 12, and the opening of the outer bag 20 is also closed with a string. The double-closed processing bag is moved to a predetermined storage location.

  Regarding the toilets at the time of disaster as described above, when the inventors of the present application investigated prior art, several related technologies were discovered.

JP 2005-46339 A Japanese Patent Laid-Open No. 10-192189 JP 2017-205449 A Japanese Patent No. 4446357

  It is common for a toilet at the time of a disaster to temporarily store a processing bag in a predetermined place and process it as garbage. For example, in a disaster toilet used in an evacuation center, a typical method is to prepare a large container with a lid for storing treatment bags outdoors and put the treatment bag in the large container with a lid. .

  When a toilet is used at the time of a disaster in a detached house or condominium where water supply or electricity has stopped, it is typical to use a large container with a lid on the veranda or common space.

  In either case, it will be “temporary storage” until administrative services such as garbage collection are restored, and the period may not be short. In such a case, there arises a problem that the odor leaks from the processing bag. Moreover, if miscellaneous germs occur, it is unsanitary.

The purpose of the present invention is to provide a technique that can suppress the occurrence of odor and the propagation of germs by devising a toilet treatment bag used in the event of a disaster.

(First idea)
The first idea in the present application is a transparent outer bag (21) having a photocatalyst (23),
An opaque inner bag (25) for placing manure in an inner space enclosed in the outer bag (21);
An inner bag closure (26) for closing the opening of the inner bag (25) containing manure;
An outer bag closing body (22) for closing the opening of the outer bag (21) in a state in which the inner bag (25) whose opening is closed by the inner bag closing body (26) is positioned in the inner bag space; ,
(Refer to FIGS. 2, 4, 5, and 6).

(Glossary)
The “photocatalyst” is a catalyst mainly composed of titanium oxide, and decomposes or sterilizes organic substances when exposed to light (ultraviolet rays). For example, a part of the surface of titanium oxide doped with iron ions coated with apatite is preferably used because it has a catalytic action even with visible light.

  The reason why the “outer bag (21)” is “transparent” is to allow the photocatalyst to react by transmitting ultraviolet rays. In addition to being colorless and transparent, it may be colored and transparent. An example of the material is polyethylene. When a photocatalyst in which a part of the surface of titanium oxide doped with iron ions is coated with apatite is employed, visible light may be transmitted.

  Regarding “outer bag (21)”, “having photocatalyst (23)” is applied to the outer bag (21) in addition to the case of being included in the material of the outer bag (21) (see FIG. 3). This is intended to include such cases (see FIGS. 4 and 6).

  The “occlusion body (22, 26)” provided in the outer bag closure body (22) and the inner bag closure body (26) includes a double-sided tape, a rubber band, a simple fastener structure, etc., and an upper periphery of the bag body (21, 25). There is a string that wraps around the bag to make the bag like a drawstring bag.

(Function)
The opening of the outer bag (21) is opened, and the opening of the inner bag (25) positioned in the inner space of the outer bag (21) is also opened. Then, urine is put (excreted) into the inner bag (25). After that, the opening of the inner bag (25) is closed with the inner bag closing body (26). Since the inner bag (25) is opaque, it contributes to suppression of discomfort.

  Subsequently, the opening of the outer bag (21) is closed by the outer bag closing body (22). Microorganisms and viruses may be generated due to organic matter leaking from the inner bag (25). However, since the outer bag (21) has a photocatalyst (23) and the outer bag (21) is transparent, ultraviolet rays pass therethrough. Therefore, the photocatalyst (23) exposed to ultraviolet rays can decompose organic substances to suppress the generation of odors and sterilize microorganisms. When a part of the surface of titanium oxide doped with iron ions is covered with apatite as the photocatalyst (23), not only ultraviolet rays but also visible light decomposes organic matter, bacteria and viruses. Demonstrates the ability to sterilize

  Of course, the treatment bag (20) according to the present invention can be used to contain stool, vomit, filth accompanying care, and pet urine. It can also be used in garbage bags such as garbage. It is also effective as a bag for temporarily storing food such as meat. This is because the generation of odor can be suppressed.

(Variation 1)
The processing bag (20) according to the first device may have a photocatalyst (23) on a part or all of the inner surface of the outer bag (21). (See FIGS. 4 and 6).

(Variation 2)
The inner bag (25) in the treatment bag according to the first device may have a photocatalyst (23) on a part or all of its outer surface.

(Variation 3)
The first device may be formed as follows.
That is, a storage container (30) for storing the outer bag (21) whose opening is closed by the outer bag closure body (22) is provided, and the storage container (30) is transparent (see FIG. 2).
The storage container (30) is preferably provided with a container lid (32) and can accommodate a plurality of outer bags (21).

(Function)
A storage container (30) stores the outer bag (21) whose opening is closed by the outer bag closing body (22). Since the storage container (30) is transparent, the reaction of the photocatalyst (23) of the outer bag (21) is not hindered.

According to the first device, it is possible to provide a treatment bag that contributes to the suppression of odor generation and miscellaneous germination for toilets used in disasters and the like.

(Figure 1)
FIG. 1 shows a procedure for using an emergency toilet that is used when a disaster occurs and water supply or electricity stops. The emergency toilet includes a toilet 10 assembled for emergency use and a processing bag 20 used as a disposable for the toilet 10.

  The toilet 10 includes a box-shaped main body 11 having an open upper surface and a frame-shaped toilet seat 12 that covers an upper edge of the main body 11 that is opened. The said processing bag 20 will be set to the internal space 13 of the main body 11 which will be located inside the toilet seat 12 (FIG. 1 (a)).

  The treatment bag 20 includes a transparent outer bag 21, an opaque inner bag 25 that is placed in an inner space enclosed by the outer bag 21, and contains manure, and an opening of the inner bag (25) after the manure is placed. And an outer bag closing body 22 for closing the opening of the outer bag 21 (FIG. 1C). Although the inner bag closing body 26 and the outer bag closing body 22 are illustrated as strings, double-sided tape or the like may be used.

  The openings of the outer bag 21 and the inner bag 26 are widened to cover the toilet seat 12 of the toilet 10, and the bottom sides of the outer bag 21 and the inner bag 26 are pushed into the inner space 13 (FIG. 1B). In that state, when used as a toilet and putting urine or filth into the inner bag 25, the opening of the inner bag 25 is closed by the inner bag closing body 26, and then the opening of the outer bag 21 is closed by the outer bag closing body 22. Close (FIG. 1 (c)).

(Figure 3)
FIG. 3 shows the structure of the outer bag 21. The outer bag 21 contains the photocatalyst 23 in the transparent polyethylene 24 (FIG. 3A).

  In FIG. 3B, the photocatalyst 23 is enlarged and modeled. The photocatalyst 23 used in this embodiment comprises titanium oxide 23A doped with iron ions and apatite 23B that partially (not entirely) cover the outer surface of the titanium oxide 23A. Apatite 23B is excellent in adsorption power, and is expected to have the effect of trapping viruses and making them immobile regardless of whether or not ultraviolet rays are irradiated. Further, it avoids direct contact between the polyethylene 24 and the titanium oxide 23A, and also plays a role of exerting a function as a photocatalyst. In other words, since the photocatalyst 23 can be included when the outer bag 21 is manufactured, the photocatalyst 23 can be provided without passing through the manufacturing process of applying the photocatalyst 23 to the inside of the outer bag 21 or the like. .

  From the inner bag 25 after use, organic substances and microorganisms that cannot be prevented from leaking by the inner bag closing body 26 come out inside the outer bag 21. Microorganisms and viruses are generated due to leaked organic matter. However, the outer bag 21 contains a photocatalyst 23. And since an outer bag (21) is transparent, both an ultraviolet-ray and visible light let it pass. Therefore, the photocatalyst 23 exposed to ultraviolet rays or visible light can decompose organic substances and suppress the generation of odors, or sterilize microorganisms and viruses.

(Figure 2)
FIG. 2 shows a procedure for storing the processing bag 20 after use shown in FIG.

  The storage container 30 includes a box-shaped container body 31 having an open upper surface, and a flexible container lid 32 that can close the opening of the container body 31 with a simple fastener (not shown). The container lid 32 is opened, and the used processing bag 20 is put into the container body 31 through the opening of the container body 31 (FIG. 2A). Then, the opening is closed by the container lid 32. Before closing, the deodorized powder is put into the container main body 31 from the deodorized powder bag 40 containing the powder for deodorization (powder such as activated carbon) (FIG. 2B).

  Since the container main body 31 and the container lid 32 are both transparent materials, the function of the photocatalyst 23 contained in the outer bag 21 is not hindered (FIG. 2C). For this reason, even if “temporary storage” is prolonged until administrative services such as garbage collection are restored, it can be expected to suppress the generation of odor in combination with the action of deodorized powder.

(Fig. 4)
The second embodiment will be described with reference to FIG. In the second embodiment, the photocatalyst 23 is applied to the inner surface of the outer bag 21. Although it may be applied to the entire inner surface, the opening side of the outer bag 21 is easily peeled off when it is closed by the outer bag closing body 22, so in this embodiment, it is applied near the opening side. Not done.

  Also in the second embodiment, it was recognized that the photocatalyst 23 decomposes the organic matter leaked from the inner bag 25 after use to suppress the generation of odor and sterilize microorganisms.

  In addition, the outer bag 21 in 2nd embodiment is good also as the polyethylene 24 containing the photocatalyst 23 as shown in FIG. 3, and good also as an outer bag formed only with polyethylene. The same applies to third and fourth embodiments described later.

(Fig. 5)
A third embodiment will be described with reference to FIG. In the third embodiment, the photocatalyst 23 is applied to the outer surface of the inner bag 25. Also in the third embodiment, the effect of suppressing the generation of odor by sterilizing the organic matter and the like leaked from the inner bag 25 after use and suppressing the generation of odors or sterilizing microorganisms was recognized.

(Fig. 6)
A fourth embodiment will be described with reference to FIG. In the fourth embodiment, the photocatalyst 23 is applied to the inner surface of the outer bag 21 and the outer surface of the inner bag 25. Also in the fourth embodiment, the effect of suppressing the generation of odor by sterilizing the organic matter and the like leaked from the inner bag 25 after use to suppress the generation of odors or sterilizing microorganisms was recognized.

The present invention has applicability in the manufacturing industry of disaster supplies, goods for the disabled, or automobile goods, or rental of disaster supplies.
