Abstract:
A container for selectably changing the temperature of its contents by mixing two reactants, comprising:a container body having a material chamber for containing said contents, a first end having a releasable closure for access to the contents of said material chamber, and a second end;a thermic module having an actuator at a proximal end attached to said second end of container body and an elongated portion extending distally into said material chamber towards the first end of said container body, said actuator having an elongated puncturing member extending distally into said elongated portion of said thermic module, said puncturing member movable from a retracted position to an extended position in response to a user applying a force to a portion of said actuator with said container body in a first upright orientation in which said second end of said container body is uppermost; anda breakable barrier in said thermic module interposed between a first chamber in said thermic module containing a liquid reactant and a second chamber in said thermic module containing a solid reactant, said first chamber disposed relatively more distally from said proximal end than said second chamber and closer to said first end of said container body than said second chamber, said puncturing member extending toward said breakable barrier and breaking said barrier to allow mixing of said reactants when said puncturing member moves to said extended position and said container body is inverted into a second upright orientation in which said first end of said container body is uppermost, allowing said liquid reactant to flow downwardly through said breakable barrier into said second chamber.
