Abstract

Abstract The invention relates to heating containers and, more particularly, to a handy heating container in which food or drink, canned or otherwise, to be heated, such as "sake", coffee, soup, curry, or the like, is set ready for being heated. The heating container has a water discharge device provided on the underside of a solution package containing water or a solution consisting principally of water; and the solution package and a heat generating material are housed in a retainer portion. With this arrangement, exothermic reaction progresses upward from the bottom portion of the heat generating material so that the can is efficiently heated. Furthermore, any water vapor produced is absorbed by the upper portion of the heat generating material so that water vapor jetting through the gap between the can and the container or blowing out of the can is effectively prevented.
