An container for holding a material, such as a food, beverage or medicine, includes a cap and a container body. The container body has a material cavity unitarily formed with a reactant cavity. The reactant cavity contains a solid reactant, and the cap contains a liquid reactant that, when mixed, produce an endothermic or exothermic reaction, depending upon the reactants selected. The cap has a tubular body section with an actuator disc 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 prongs extending from the inner surface of the disc toward the barrier. When a user depresses the actuator disc, it flexes inwardly and moves the prongs toward the barrier. The reactants mix when the prongs puncture the barrier. Heat transferred between the two cavities heats or cools the material. The wall of the container that defines the reactant cavity may be pleated or corrugated to promote heat transfer.

A container for selectably changing the temperature of a stored material by mixing two reactants, comprising: a generally tubular unitarily formed container body having a material cavity for containing said stored material and a reactant cavity for containing a first reactant, said reactant cavity having an opening at a first end of said container; a cap disposed in said opening at said first end of said container, said cap having a cap body, a flexible member unitarily formed with said cap body, and an elongated member integrally formed with said cap body, said flexible member having an inner surface and an outer surface, at least one point on said inner surface moving in at least a partially axial direction with respect to said container body between a retracted position and an extended position in response to an axial force experienced on said outer surface of said flexible member, said elongated member comprising a hollow prong having a longitudinal notch and having a proximal end disposed at said point and a distal end projecting from said point; a breakable barrier attached to an open end of said cap for retaining a second reactant in said cap, said distal end of said elongated member extending beyond said open end of said cap when said point on said inner surface is in said extended position; and a removable closure at a second end of said container body for providing access to said stored material in said material cavity.
