CHEMICAL HEATING COMPOSITIONS AND METHODS

摘要

A user-activatable, single-use chemical heater that includes at least one compartment of a first type separated from at least one compartment of a second type by a separator that is compromisable by a user to establish communication therebetween. Water and ingredients of a heating system that generates heat by an oxidation-reduction reaction between aluminum metal and a water-soluble copper halide are stored in and divided between the compartments of the first and second types so as not to initiate the heat-generating reaction until the contents of the compartments of the first and second types mix following compromise of said separator.
