Abstract
A heating device comprises a heating chamber defining an interior space for receiving and storing a substance to be heated, a heater for use as a source of heat which includes a reaction chamber, a solid state reaction composition disposed within the reaction chamber such that it is physically isolated from and in thermal communication with the interior space of the heating chamber, an activation mechanism in communication with the composition disposed within the reaction chamber, and wherein the reaction composition is inert until the activation mechanism is actuated. Activation mechanism comprises an actuator having a user interface portion and an actuation portion, and the actuation portion carries a reaction initiation material that, when assembled with the heater, is capable of initiating a chemical reaction in the chemical composition when the actuation portion is actuated by a user.
