In FIG. 5, the longitudinal cross-sectional view of the transpiration | evaporation apparatus 60 using the conventional hydration exothermic container is shown.
The transpiration apparatus 60 is generally configured by a self-heating container 70 and an outer container 61 composed of a side wall 62 and a bottom wall 63 that are spaced apart from the side wall and bottom wall of the self-heating container 70.
The self-heating container 70 has an inner container 71 whose upper end is opened. The inner container 71 is filled with a hydrothermal substance 72 and the upper end of the inner container 71 is closed so as to cover the hydrothermal substance 72 with a water container 80. Furthermore, the upper wall 80 a of the water container 80 is covered with an upper lid 73. A convex portion 73a is formed in the approximate center of the upper lid 73, and a transpiration hole 73b for discharging the steam generated in the inner container 71 is formed around the convex portion 73a.
The water container 80 has a configuration in which the lower end of the cylindrical body is sealed with a film 82. An aqueous solution 81 containing an active ingredient is sealed in the water container 80. Further, the water container 80 is provided with a film breaking pin 83 that penetrates substantially the center of the upper wall 80a and is connected to the upper wall 80a through a thin portion 80b. The upper end of the pin 83 is in contact with the inner surface of the convex portion 73 a formed at the approximate center of the upper lid 73.
An inner pressure adjusting hole 64 is provided in the bottom wall 63 of the outer container 61.
[0004]
In order to evaporate the active ingredient in the aqueous solution 81 using the transpiration device 60 described above, the convex portion 73a of the upper lid 73 of the self-heating container 70 is pushed downward in the figure (in the direction of arrow A), and the thin portion 80b is The film 82 is broken. Then, the aqueous solution 81 is supplied to the hydrothermal exothermic substance 72, and the hydrothermal exothermic substance 72 is heated by the moisture, and the active ingredient is evaporated by the heat.

The vapor evaporation path was formed by breaking the thin portion 80b and the film 82.
In the transpiration apparatus 60 having such a configuration, the sealing performance of the water container 80 is not sufficient. That is, there is a possibility that the thin-walled portion 80b of the water container 80 is damaged during transportation of the product and the aqueous solution 81 leaks from the damaged portion. In addition, the stability of the hydrothermal exothermic substance 72 may be impaired due to the thin wall.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a water heating exothermic container in which the water container has good sealing properties and a simple structure.

[Means for Solving the Problems]
As a result of intensive studies, the present inventor has provided small openings in the side wall and bottom wall of the self-heating container, so that the aqueous solution does not leak from the opening to the outside of the self-heating container during use, and only the vapor containing the active ingredient is used. It was found that it was discharged from the opening. That is, when an appropriate amount of aqueous solution is supplied to the hydrothermal exothermic substance, the water in the aqueous solution is absorbed by the hydrothermal exothermic substance before reaching the opening.
[0007]
The object of the present invention is to provide a self-heating heat generating container having a water container containing an aqueous solution containing an active ingredient, a self-heating container containing a water-heating substance, and an outer container containing the self-heating container. The container has an upper wall, a side wall, and a bottom wall, the water container is disposed on the upper wall side, the hydrothermal exothermic substance is disposed on the bottom wall side, and at least one of the side wall or the bottom wall, When the water container is ruptured by a break pin provided in the water container , the steam containing the active ingredient generated by the heat of the hydrothermal exothermic material generated by the water of the aqueous solution supplied from the water container is removed from the outside. A discharge hole is provided in the container, and a transpiration hole is provided in the outer container for evaporating the vapor containing the active ingredient discharged from the self-heating container to the outside. Addition It can be achieved by heating type container.
[0008]
According to the hydration exothermic container having the above-described configuration, the steam containing the active ingredient is discharged from the self-heating container into the outer container and evaporated from the transpiration hole of the outer container to the outside. Accordingly, the discharge hole can be disposed at any position on the side wall and the bottom wall of the self-heating container, and it is not necessary to provide a thin portion in the water container, so that the sealing performance of the water container is improved.
[0009]
In the present invention, it is preferable that the discharge hole is provided in a bottom wall of the self-heating container, and a ventilation member for closing the discharge hole is provided in the self-heating container.
[0010]
According to the hydrothermal exothermic container configured as described above, the aqueous solution can be more reliably prevented from leaking into the outer container. That is, even if the amount of the aqueous solution supplied to the hydrothermal substance is large, the aqueous solution can be used without waste by keeping the aqueous solution in the self-heating container. Therefore, the high transpiration effect by an active ingredient can be acquired.
[0011]
In the present invention, it is preferable that a substance to be heated impregnated with an active ingredient is disposed on at least one of the outer surface of the side wall or the outer surface of the bottom wall of the self-heating container.
[0012]
According to the water heating exothermic container having the above-described configuration, the active ingredient evaporated from the heated material and / or the active ingredient evaporated from the aqueous solution is evaporated by using the heat generated from the self-heating container. By selectively using the active ingredients, a high transpiration effect by these active ingredients can be obtained.
[0013]
The self-heating container may be stored in the outer container so that a part of the self-heating container is exposed to the outside. For example, the top wall of the self-heating container may be exposed to the outside of the outer container, and the side wall and the bottom wall may be stored in the outer container.
Examples of the hydrothermal exothermic substance include articles that generate heat only by adding water, such as calcium oxide, magnesium chloride, aluminum chloride, calcium chloride, and iron oxide. A method in which a mixture of iron and at least one of potassium sulfide, iron sulfide, metal chloride, iron sulfate, etc. is brought into contact with water and oxygen, a metal ionization tendency larger than iron and a metal halide tendency less ionization than iron Examples include a method in which a mixture of the above is brought into contact with water, a method in which a mixture of metal and bisulfate is brought into contact with water, and a method in which water is added to a mixture of aluminum and an alkali metal nitrate.
In the case where oxygen is brought into contact with the hydrothermal material, a self-heating container and an outer container may be provided with a vent hole for supplying oxygen to the hydrothermal substance, or the self-heating container is a breathable container, and the outer container has a vent hole. It may be provided.
It is preferable that the aqueous solution dissolves at least one of active ingredients such as a deodorant, an insecticide, a bactericide, and a fragrance.
[0014]
Although the shape of a water container is not limited, an aluminum bag, a plastic bag, a plastic container, etc. can be employ | adopted.
In order to prevent the water in the water container from decaying when not in use, a liquid stabilizer such as a disinfectant may be added to the water. Liquid stabilizers include alcohols, benzethonium chloride, benzalkonium chloride, sucrose, alkyldiaminoethylglycine chloride, chlorhexidine gluconate, cetylpyridinium chloride, sodium lauryl sulfate, sodium dehydroacetate, chlorinated isocyanuric acid, Powder etc. can be selected. As alcohols, methanol, ethanol, isopropyl alcohol and the like can be used.
[0015]
The amount of the liquid stabilizer added cannot be said to be exact depending on the type of the liquid stabilizer, but in the case of alcohols, it will be explained separately because a large amount is used unlike other cases. In the case of the liquid stabilizer, since there is a practical antiseptic effect at a concentration of 0.1 wt / vol% (may be expressed by [w / v%]), for example, 0.1 to 2 w / v% However, if it is less than that, it can be used if there is an effect of stabilizing the liquid. If the amount added is increased, the viscosity of the liquid increases and the fluidity of the reaction liquid decreases, so it is better to be as low as possible.
Further, when the liquid stabilizer is an alcohol, it can be used up to 50 vol / vol% (sometimes referred to as [v / v%]) with respect to water. If it exceeds / v%, the effect is lost. The lower limit is about 5 v / v%, but preferably 10 v / v% or more. Although it varies depending on the type of alcohol, it is most preferably 10 to 30 v / v%. For this reason, in the case of alcohols, it is necessary to make the addition amount and the optimum amount.
[0016]
The liquid stabilizer may be added to a mixture of water and another organic solvent. Further, a bactericidal active substance may be applied or kneaded into the water container itself.
As the material of the outer container, paper, wood, plastic, or the like can be used.
The ventilation member refers to a material that has vapor permeability and does not have water permeability. For example, a microporous sheet etc. are mentioned.
Although the substance to be heated is not limited, deodorizers, insecticides, bactericides, fragrances, etc. can be considered as transpiration agents, and as those impregnated, dissolved, supported, for example, mats, granules, liquids, etc. It is done.
