Abstract
Self-heating systems for rapidly and effectively heating a comestible substance are disclosed. Self-heating systems generally include a reaction chamber and a heating chamber. The heating chamber contains a substance to be heated. The reaction chamber contains reactants that, when contacted, exothermically react. The containers and reactants can be configured to heat at least six fluid ounces of comestible substance in less than one minute. The solid chemical reactant mixture can comprise magnesium chloride, calcium chloride, and/or calcium oxide. Methods for heating at least six fluid ounces of comestible substance in less than one minute are also provided.
Claims6
A container for a comestible substance, comprising:
- an outer body, said outer body having a height of between about 5 to 8 inches and an average cross-sectional area of between about 3 to 4 square inches;
- a heating chamber disposed within the outer body, said heating chamber having a volume adapted to receive between about 10 to 18 fluid ounces of a comestible substance;
- a reaction chamber disposed within the outer body, said reaction chamber is adapted to house a predetermined amount of reactants and allow the reactants to undergo an exothermic chemical reaction and generate heat;
- and
- wherein the coefficient of heat transfer from the reaction chamber to the comestible substance is at least between about 0.0167 BTU/(ft2·sec.·° F.) to 0.0833 BTU/(ft2·sec.·° F.) such that the temperature of the comestible substance can be raised from room temperature to about 145° F. within one minute of the initiation of the exothermic chemical reaction and that the temperature of the comestible substance does exceed about 212° F.
