Abstract
A thermic module for heating or cooling a material in a container produces an exothermic or endothermic reaction when a user presses an actuator button that causes two reactants in the module to mix. The module is removably engageable in an opening of a container by, for example, screwing it into a threaded opening. The container may have a double-walled construction, with a vacuum space between the inner and outer walls to slow heat transfer after the contents have reached the intended temperature. The module may thus be used to heat or cool beverages or foods in a conventional THERMOS-type vacuum bottle by using the module in place of the normal screw cap.
