A container having a container body, a thermic module, and a closure heats or cools its contents by initiating a chemical reaction inside the thermic module when a user activates the container. The thermic module may include a module cap and a module body. Two reactants, such as calcium oxide and water, are retained in portions of the thermic module and separated by a barrier that is punctured when a user activates the container, thus allowing them to mix. The cap may have vent channels between surfaces of the module cap and the module body that allow gases to vent, yet prevent escape of unsightly solid particles. A filter ring may be included in the path of each vent channel to further prevent such escape.

[ What is claimed is:] [1.] A container for selectably changing the temperature of a material by mixing two reactants, comprising:a container body having a material cavity for containing said material;a openable closure disposed in a wall of said container body for providing access to said material cavity;a thermic module disposed in a wall of said container body and extending at least partially into said container body, said thermic module comprising an actuator, an elongated member movable between a retracted position and an extended position in response to a force experienced by a portion of said actuator, a breakable barrier, two chambers for containing said reactants separated from one another by said breakable barrier, and a plurality of vents for venting gas from said chambers, a distal end of said elongated member extending through said breakable barrier when said elongated member is in said extended position; anda filter element disposed in interfering relation to said vents.
