Abstract
A self-heating container is capable of generating heat by hydration of an exothermic reaction agent and includes a body, a cover for closing the body, an inner container placed in the body for containing foodstuff to be heated, a primary water bag for supplying water for initial hydration, and an envelope enclosing an exothermic reaction agent and a secondary water bag. The amount of water necessary for hydration of the exothermic reaction agent is divided between the primary and secondary water bags so that water may be supplied in two stages to avoid violent eruption of hot steam due to hydration. In operation, the primary water bag is, after opened, removed from the body to discharge water for the initial hydration of the exothermic reaction agent which generates heat for rupturing the secondary water bag. Then the secondary water bag discharges water for further hydration.
