ABSTRACT:
A heating device useful for a variety of relatively small heating applications is disclosed. The heat source for the device comprises a hermetically sealed cartridge containing a chemical mixture which produces heat, but substantially no gas, upon ignition. The device itself comprises a thermal-conductive body into which the cartridge is inserted and an insulating cover for all but a portion of the body. The body is constructed for optimizing heat transfer from the cartridge to such exposed portion. The exposed portion may be employed as a grill, or a container may be releaseably secured to the exposed portion for use as a warming pan for liquid or semi-solid substances. Alternately, the body may include one or more recesses for receiving specially shaped food items such as sausages, frankfurters or food packets. The use of a plurality of heating cartridges in the device can increase the heating temperature, prolong the useful heating capacity and/or extend the usefulness of the device for heating larger quantities of foods or liquids.
