Self-heating container
First Claim
1. A self-heating container comprising:
- an inner casing fixed to and inside said container,a heater contained in said casing and including a pyrogen and a firing agent in contact with said pyrogen,said pyrogen comprising a mixture of at least one kind of metal oxide powder and at least one kind of powder of elementary substance or an alloy of metal and semimetal,said firing agent being easier to fire than said pyrogen, and comprising a mixture of at least one kind of metal oxide powder and at least one kind of powder of elementary substance or alloy of metal and semimetal,a heat insulator contained in said casing under said pyrogen and insulating said heater from said container,said insulator having a bore formed therethrough and extending between said firing agent and the outside of said container, andan igniter adapted to generate sparks by friction heat, at least a separate component of said igniter being normally supported by said container away from said heater and being adapted to be inserted into said bore.

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.

2. A self-heating container comprising:
-
a casing fixed to said container, a heater contained in said casing and including a pyrogen and a firing agent in contact with said pyrogen, said pyrogen comprising a mixture of at least one kind of metal oxide powder and at least one kind of powder of elementary substance or an alloy of metal and semimetal, said firing agent being easier to fire than said pyrogen, and comprising a mixture of at least one kind of metal oxide powder and at least one kind of powder of elementary substance or alloy of metal and semimetal, and a heat insulator contained in said casing under said pyrogen and insulating said heater from said container, said insulator having a bore formed therethrough and extending between said firing agent and the outside of said container to receive at least part of an igniter, and said container comprising a cylindrical peripheral wall, wherein said casing is cylindrical and includes an upper portion surrounding said pyrogen and said firing agent and a lower portion surrounding said insulator, said first portion being substantially smaller in diameter than said second portion, said second portion being slightly smaller in diameter than said peripheral wall.
