Abstract
A self-heating container comprising a heater contained in a container. The heater includes a pyrogen of high energy density having a large heating value, and a firing agent contacting the pyrogen and easier to fire than the pyrogen. Each of the pyrogen and the firing agents is a mixture of one or more kinds of metal oxide powder and one or more kinds of powder of elementary substances or alloys of metal and semimetal. The heater is supported on a wall of the container through a heat insulator to reduce the heat loss. The insulator has a bore formed through it and extending between the firing agent and the outside of the container. An igniter can be inserted into the bore to ignite the firing agent.
