ABSTRACT:
An outer container for holding a material, such as a food, beverage or medicine with a sealed thermic module inside the container. The thermic module contains chemical reactants that mix upon actuation of the container by a user. Mixing of the reactants produces an exothermic or endothermic chemical reaction, depending upon the reactants selected. The contents of the outer container surround a portion of the outside surface of the thermic module, thereby facilitating conduction of heat. The thermic module has a hollow module body that is closed at one end and a module cap that seals the other end of the module body. The module body contains the solid reactant, and the module cap contains the liquid reactant. The module cap has a tubular section with a flexible member closing one end and a breakable barrier closing the other end. With the exception of the barrier, the cap is of unitary construction. The cap has one or more integrally formed prongs extending from the inner surface of the disc toward the barrier. The prongs move in an axial direction toward the barrier and may also spread apart radially when the outer surface of the flexible member or an actuator connected to it is depressed by the user's finger. The dual motion of the prongs in both axial and radial directions promotes complete puncturing of the barrier and thus fast mixing of the reactants.
