ABSTRACT:
A self-heating container is capable of generating heat by hydration of an exothermic rection agent and includes an outer shell, an envelope enclosing the exothermic reaction agent, a water bag filled with water for reaction with the agent, and a container body for containing foodstuff. The container body is formed of a sheet member including a metal foil and a synthetic resin layer attached on at least one side of the metal foil. The sheet member is folded to have a W-shaped cross section and is heat-sealed along the vertical and upper edges. The inverted V-shaped portion of the folded sheet defines a chamber for accommodating the envelope outside the container body.
