ABSTRACT:
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.
