SUMMARY OF THE INVENTION The above-described transpiration device 60
In the above, the steam containing the active ingredient of the drug is
The water container 80 is provided with a film 82 and a thin portion 80b in order to pass through the inside and evaporate from the evaporation hole 73b, and the thin portion 80b and the film 82 are broken at the time of use to form a steam evaporation path. Was. In the evaporation device 60 having such a configuration, the water container 80 was not sufficiently sealed. That is, the thin portion 80b of the water container 80 may be damaged during transportation of the product, and the aqueous solution 81 may leak from the damaged portion. In addition, because of its thin thickness, the hydrothermal substance 72
There was a fear that the stability of the garment could be impaired. The present invention has been made in view of the above problems, and an object of the present invention is to provide a hydrothermally heated container having a simple structure, in which the water container has good sealing properties.

[0006]

Means for Solving the Problems As a result of intensive studies, the present inventor has found that when small openings are provided in the side wall and bottom wall of the self-heating container, the aqueous solution does not leak from the openings to the outside of the self-heating container during use. It has been found that only the vapor containing the active ingredient is discharged from the opening. That is, when an appropriate amount of an aqueous solution is supplied to the hydrothermal substance, the water content of the aqueous solution is absorbed by the hydrothermal substance before reaching the opening.

[0007] The object of the present invention is to provide a hydrothermally heated container having a water container for storing an aqueous solution containing an active ingredient, a self-heating container for storing a hydrothermal substance, and an outer container for storing the self-heating container. The self-heating container has a top wall, a side wall, and a bottom wall, the water container is disposed on the top wall side, the hydrothermal substance is disposed on the bottom wall side, and at least the side wall or the bottom wall is provided. On the other hand, a discharge hole for discharging the vapor containing the active ingredient into the outer container is provided, and in the outer container, the vapor containing the active ingredient discharged from the self-heating container evaporates to the outside. Can be attained by a water-heating / heat-generating container characterized by having a transpiration hole.

[0008] According to the water-heating type container having the above-described structure, the vapor containing the active ingredient is discharged from the self-heating container to the inside of the outer container, and is evaporated to the outside through the evaporation hole of the outer container.
Therefore, a discharge hole can be provided 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 water container is improved in sealing performance.

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 water heating / heating type container configured as described above, it is possible to more reliably prevent the aqueous solution 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 retaining the aqueous solution in the self-heating container.
Therefore, a high transpiration effect by the active ingredient can be obtained.

Further, 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 and the outer surface of the bottom wall of the self-heating container.

[0012] According to the water-heating and heating type container having the above-described structure, the active ingredient evaporated from the substance to be heated and / or the active ingredient evaporated from the aqueous solution is evaporated using the heat generated from the self-heating vessel. By doing so, a high transpiration effect by these active ingredients can be obtained by selective use of the active ingredients.

[0013] The self-heating container may be housed in an outer container so that a part of the container is exposed to the outside. For example, the upper 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 housed in the outer container.
As hydrothermal substances, calcium oxide, magnesium chloride, aluminum chloride, calcium chloride, iron oxide, etc.
An article that generates heat only by adding water can be exemplified. A method in which a mixture of iron and at least one of potassium sulfide, iron sulfide, metal chloride, and iron sulfate is brought into contact with water and oxygen; a metal having a higher ionization tendency than iron and a metal halide having a lower ionization tendency than iron; Contacting the mixture with water
Examples include a method in which a mixture of a metal and a bisulfate is brought into contact with water, a method in which water is added to a mixture of an aluminum and an alkali metal nitrate, and the like. In the case where oxygen is brought into contact with the hydrothermally generated substance, a vent or the like for supplying oxygen to the hydrothermally exothermic substance may be provided in the self-heating container and the outer container. It may be provided. The aqueous solution preferably dissolves at least one of active ingredients such as a deodorant, an insecticide, a bactericide, and a fragrance.

The shape of the water container is not limited, but an aluminum bag, a plastic bag, a plastic container or the like can be used. In order to prevent the water in the water container from spoiling when not in use, a liquid stabilizer such as a disinfectant may be added to the water.
Examples of the liquid stabilizer include alcohols, benzethonium chloride, benzalkonium chloride, sucrose, alkyldiaminoethylglycine chloride, chlorhexidine gluconate, cetylpyridinium chloride, sodium lauryl sulfate, sodium dehydroacetate, chlorinated isocyanuric acid, and high-grade salacinol. Powder etc. can be selected. As the alcohols, methanol, ethanol, isopropyl alcohol and the like can be used.

The amount of the liquid stabilizer to be added cannot be said to be different depending on the type of the liquid stabilizer, but in the case of alcohols, unlike the other cases, a large amount is used. In the case of a liquid stabilizer other than alcohols, a concentration of 0.1 wt / vol% (sometimes represented by [w / v%]) has a practical antiseptic effect. / V%, but if it is less than that, it can be used as long as it has a liquid stabilizing effect. As the amount of addition increases, the viscosity of the solution increases, and the fluidity of the reaction solution decreases. Therefore, the lower the better, the better. When the liquid stabilizer is alcohols,
Although it can be used up to 50 vol / vol% (may be referred to as [v / v%]) with respect to water, it differs depending on the type of alcohol, and if it exceeds 50 v / v%, the effect is lost. The lower limit is about 5 v / v%, but 10
It is preferably at least v / v%. Although it depends 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.

Further, 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 and the like can be mentioned. Although the substance to be heated is not limited, deodorants, insecticides, bactericides, fragrances, and the like can be considered as agents for transpiration. Can be
