PROBLEM TO BE SOLVED: To solve such problems with the chemicals for transpiration for the conventional transpiration device that, depending upon the kinds of the chemicals for transpiration are insoluble in water and in some cases, the chemicals, when dissolved in the water, retard an exothermic reaction, peel the adhesive surfaces of the film adhered to the base surface section of a water container, give rise to the inconvenient exothermic reaction and are unusable in actuality. SOLUTION: This transpiration device is constituted by putting exothermic agents which generate heat when water is added thereto and the chemicals for transpiration into a thermal insulating vessel opened at its top end and capping the top end with a water container. The water container is spread with a rupturable film at its base surface section and the top surface section is provided with a film rupturing member which ruptures the film when the center of the top surface section is pushed. Further, a juncture between the film rupturing member and the top surface section is provided with a thin part. |
