Abstract
A mixture of an active ingredient such as insecticide, fungicide, antiseptic or the like and a blowing agent is heated indirectly with a heat evolved by contacting an exothermic substance with water to decompose the blowing agent and to volatilize the active agent. The mixture is accommodated in at least one compartment of a container while the exothermic substance is accommodated in at least one further compartment provided with water supplying means, said compartments being separated from each other by a partition which provides a heat transferring surface.
