Description

[Technical Field]

[0001] The present invention relates to a disaster toilet set that can be used when flush toilets become unusable due to a disaster such as an earthquake. [Background technology]

[0002] In the event of an earthquake or other disaster, the water supply and sewerage systems may be destroyed, rendering flush toilets unusable, and depending on the nature of the disaster, restoration may take a long time. In such cases, emergency toilets have no choice but to be used, and many proposals have been made for this purpose.

[0003] For example, Patent Document 1 describes a toilet product for emergencies, in which the core of toilet paper is removed and multiple sticks containing coagulant powder are placed inside, along with multiple sealed disposal bags. This product coagulates excrement and stores it in the disposal bags. However, if excrement is coagulated and stored in a disposal bag after each use, multiple disposal bags are required. Therefore, if multiple excrements are disposed of using the same bag, odors from previous excrement become a problem.

[0004] To solve this odor problem, Patent Document 2 describes a method in which a deodorizing component is dispersed in a coagulant, and water and the coagulant are added to the excrement to coagulate it into a jelly-like substance. The coagulant described is a polyacrylate, and the deodorizing component is granular activated carbon or zeolite. However, these deodorizers that physically adsorb odorous components take a long time to deodorize and are unable to adsorb odorous components in areas that are not in contact with the deodorizer. Therefore, a large amount of deodorizer is required to enhance the deodorizing effect, which increases costs and also increases the weight and volume of the waste.

[0005] Patent Document 3 also describes an aerosol composition that forms foam that covers the surface of odorous substances. This aerosol composition contains 10-20% propellant, 20-30% surfactant, and 55-65% water. However, because the water content is high relative to the surfactant, it does not form a hard, firm foam layer. Therefore, although it is suitable for everyday toilet deodorization, its odor-suppressing effect decreases when attempting to dispose of multiple excrements using the same bag in the event of a disaster. Furthermore, the large amount of water (55-65%) increases the weight and volume of the waste. Therefore, although it is suitable for everyday toilet deodorization, it is unsuitable for use in disasters, where waste volume must be minimized. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Utility Model Registration No. 3244043 [Patent Document 2] Japanese Patent Application Laid-Open No. 2000-157998 [Patent Document 3] Japanese Patent Application Laid-Open No. 2001-112858 Summary of the Invention [Problem to be solved by the invention]

[0007] The object of the present invention is to solve the problems of the prior art described above, and to provide a disaster toilet set that allows multiple disposal of excrement using the same bag without being bothered by odors during a disaster, and that also prevents an increase in the amount of waste. [Means for solving the problem]

[0008] The present invention, which was made to solve the above problems, is a disaster toilet set that contains a deodorizing spray can that sprays foam to cover excrement, multiple resin bags, and a coagulant inside a box body, and is characterized in that the deodorizing spray can contains 25 to 40% by mass of a surfactant, 40 to 55% by mass of water, and a propellant.

[0009] The box is preferably sized to accommodate two or four rolls of toilet paper. An aliphatic amine derivative can be used as the surfactant. The box may also contain multiple baby wipe sheets. [Effects of the Invention]

[0010] The emergency toilet set of the present invention contains everything you need when a flush toilet is unavailable, making it convenient to stock as a disaster prevention item. If the size of the set box is set to the equivalent of two or four rolls of toilet paper, as in the embodiment described below, it has the advantage of being easy to stock in the toilet paper storage area in the bathroom.

[0011] The disaster toilet set of the present invention also includes a deodorizing spray can containing 25-40% surfactant, 40-55% water, and a propellant by mass. The foam sprayed from this deodorizing spray can is relatively hard, forming a non-breathable foam layer on the surface of the excrement that remains resistant for a long period of time. This prevents odors even when multiple excrements are made in the same plastic bag. Furthermore, because the amount of water is small, the amount of waste does not increase, and the set can be solidified with a coagulant and disposed of as compact combustible waste. [Brief explanation of the drawings]

[0012] [Figure 1] FIG. 1 is a cross-sectional view showing an embodiment of a disaster toilet set. [Figure 2] FIG. 1 is an explanatory diagram showing how to use the disaster toilet set of the embodiment. [Figure 3] FIG. 2 is a cross-sectional view showing a disaster toilet set of an embodiment different from the example shown in FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0013] An embodiment of the present invention will be described below. As shown in Figure 1, the disaster toilet set of the present invention contains a deodorizing spray can 11, multiple resin bags 12, and a coagulant 14 inside a box 10. It is preferable to enclose an instruction manual 15 or print instructions on the outside of the box 10.

[0014] While the material of the box 10 is not limited, it is preferably a paper box that is easy to dispose of, and its overall size is preferably equivalent to the size of two rolls of toilet paper. This is because box 10 can be stored perfectly in the space in the bathroom where toilet paper rolls are normally stored. For example, box 10 in this embodiment is formed with dimensions of 220 mm high x 110 mm wide x 110 mm deep.

[0015] The resin bag 12 is a bag for receiving excrement. As shown in FIG. 2-1, the resin bag 12 of this embodiment is used by being double-layered to cover the toilet bowl 20 with the seat up. For this purpose, approximately ten large, leak-proof resin bags 12 are stored. The resin bags 12 may be stored folded or rolled up. Each resin bag 12 of this embodiment is formed to have dimensions of 70 cm x 75 cm, which is large enough to cover the top surface of an average-sized household toilet bowl 20.

[0016] The coagulant 14 is not particularly limited as long as it can absorb and retain excrement such as urine, and known water-absorbent materials can be used. A suitable example of the coagulant 14 is a superabsorbent polymer, commonly used in absorbent articles such as disposable diapers. This polymer can absorb and coagulate a large amount of moisture with a small amount. As described below, the coagulant 14 is not used for each excretion, but is used to solidify the entire contents of the plastic bag 12 when it is full. In this embodiment, an amount of coagulant 14 corresponding to the number of plastic bags 12 is filled into a light-blocking, sealable aluminum pack and stored in the box 10. In this case, it is preferable that a plastic spoon for scooping the coagulant 14 from the aluminum pack is attached. The coagulant 14 may be in the form of small stick packets, for example, 10 packets, placed in a small box.

[0017] The deodorizing spray can 11 is used to spray foam that covers excrement, and contains 25 to 40% by mass of surfactant, 40 to 55% by mass of water, and the remainder being propellant.

[0018] The surfactant forms a layer of foam on the surface of the waste that is breathable and durable; in this embodiment, an aliphatic amine derivative is used. For example, "Sunfoam P-30" manufactured by Sugimura Chemical Co., Ltd., which contains an aliphatic amine derivative as its main component, can be used. The surfactant content is set to 25-40% because, below this range, it becomes difficult to form hard foam, and conversely, above this range, the foam becomes too hard, making final disposal difficult. It is more desirable for the surfactant content to be in the range of 30-40%. A small amount of a solvent component, such as isopropyl alcohol, is added to this surfactant to ensure smooth spraying.

[0019] In addition to surfactants, deodorizing spray can 11 contains 40-55% water. This adjusts the hardness of the foam layer that forms on the surface of the excrement. Water has the advantage of being easily absorbed by the coagulant 14 added during final disposal. If the water content falls below this range, the foam will be hard; conversely, if it exceeds this range, it will be difficult to form hard foam. A small amount of glue component may be added to this water to promote the generation of foam from the surfactant.

[0020] Although the propellant used is the commonly used LPG, the type of propellant is not particularly limited, and carbon dioxide or nitrogen gas can also be used. The propellant accounts for the majority of the remainder other than the surfactant and water. In addition, a small amount of antibacterial material or lavender-based fragrance can be added to the contents of the deodorizing spray can 11, but these can also be omitted.

[0021] The emergency toilet kit may contain additional contents in addition to the above-mentioned contents. For example, it may contain or include wet wipes for cleaning.

[0022] Next, a method for using the disaster toilet set of the present invention will be described. First, as shown in Figure 2-1, one plastic bag 12 is placed over the toilet bowl 20 with the seat raised, and then another plastic bag 12 is placed over that. In this state, the toilet seat is lowered, and when the user defecates, the excrement falls into the plastic bag 12 that has been placed over the toilet bowl 20, as shown in Figure 2-2.

[0023] Immediately after the end of excretion, the contents of the deodorizing spray can 11 are sprayed onto the surface of the excrement, as shown in 3 of Figure 2. As a result, the surface of the excrement is covered with a layer of relatively hard, non-breathable foam, which blocks out odors. This allows repeated excretion into the same plastic bag 12. By spraying from the deodorizing spray can 11 each time the excrement is excreted, the layers of excrement and foam gradually build up.

[0024] Once multiple loads of excrement have accumulated inside the plastic bag 12 as described above, a coagulant 14 is poured into the plastic bag 12 as shown in FIG. 2, causing the entire bag to solidify into a jelly-like substance. The moisture contributes to the successful solidification process. After the excrement inside the plastic bag 12 has solidified, the upper plastic bag 12 of the double-layered plastic bag set is removed from the toilet 20, the opening is sealed with a string or the like, and the bag is disposed of as combustible waste 21. The solidified material in this state can be disposed of as combustible waste 21, similar to diapers, without any hygienic issues.

[0025] As described above, the disaster toilet set of the present invention allows multiple disposals of excrement using the same plastic bag 12, and because the surface of the excrement is covered with a non-breathable foam layer, odors are blocked. Furthermore, since less water is used than with conventional deodorizing sprays, the amount of waste does not increase, and the excrement can be solidified with a coagulant and disposed of hygienically as compact combustible waste 21.

[0026] The emergency toilet set of this embodiment, which includes the above-mentioned 10 plastic bags 12, can be used approximately 100 times per set, and one set can be used by a family of two for one week to 10 days. The emergency toilet set of this embodiment is economical as it eliminates the need for households to stockpile multiple sets in preparation for disasters.

[0027] The disaster toilet set of the present invention is not limited to the embodiment shown in Fig. 1. Below, an embodiment other than the embodiment shown in Fig. 1 will be described with reference to Fig. 3. Note that the following mainly describes configurations that differ from the embodiment shown in Fig. 1, and similar configurations will be assigned the same reference numerals and will not be described again.

[0028] The box 10 of the emergency toilet set of this embodiment is formed to a size equivalent to four rolls of toilet paper. This size of box 10 is preferable because it allows for an increased amount of contents to be stored inside box 10 and allows it to fit snugly into the space in the toilet where toilet paper rolls are normally stored. For example, the box 10 of this embodiment is formed to have dimensions of 220 mm high x 220 mm wide x 110 mm deep.

[0029] The example of the disaster toilet set shown in Figure 3 contains a deodorizing spray can 11, multiple plastic bags 12, multiple bottom wipe sheets 13, a coagulant 14, and instructions for use 15 inside a box 10.

[0030] 3, approximately 20 resin bags 12 are stored inside the box 10. Also, an amount of coagulant 14 corresponding to the number of resin bags 12 is stored inside the box 10. Note that, although one deodorizing spray can 11 is stored in the box 10 in the illustrated example, this is not limiting, and multiple deodorizing spray cans 11 may be stored inside the box 10.

[0031] Any suitable commercially available product can be used as the baby wipe sheet 13, such as soft paper impregnated with alcohol or other liquid. However, the material of the baby wipe sheet 13 is optional and is not limited to this. If the sheet is impregnated with liquid, it is preferable to store it in a non-breathable storage bag to prevent the liquid from evaporating during storage.

[0032] If the emergency toilet set includes a wipe sheet 13, the wipe sheet 13 impregnated with alcohol or the like can be used after excretion, so that a feeling of cleanliness can be maintained even in the event of a disaster when flush toilets cannot be used.

[0033] The emergency toilet set of this embodiment, which includes the 20 plastic bags 12, can be used approximately 200 times per set, allowing a family of four to use one set for one week to ten days. The emergency toilet set of this embodiment is economical as it eliminates the need for households to stockpile multiple sets in preparation for disasters. [Explanation of symbols]
