ABSTRACT:
A container for housing and producing a liquid comestible product and in situ heating thereof has an upper comestible chamber and a lower comestible chamber separated by a comestible diaphragm. One of the comestible chambers retains a dry powder and the other comestible chamber retains water. A moveable pierce rod assembly penetrates from outside the container to inside the upper comestible chamber and is attached to an arm disposed outside of the container. A removable protective collar is disposed between the arm and the container to retain the arm and pierce rod assembly in place. A flexible collar is disposed within the protective collar to seal the pierce rod assembly between the arm and the container. The lower chamber houses an upper heating/cooling chamber and a lower heating heating/cooling chamber separated by a heating heating/cooling diaphragm. One of the heating heating/cooling chambers retains a chemical reactant and the other heating heating/cooling chamber retains water. A moveable plunger is retained by a flexible plunger diaphragm and is hand actuated from outside the container. The plunger is disposed to penetrate through and rupture the heating heating/cooling diaphragm when actuated from outside the container to combine the chemical reactant and water for generating/withdrawing heat to heat/cool the contents of the lower chamber. A dispensing tube is provided for removing the liquid comestible product from the container. Removal of the protective collar permits the pierce rod to be actuated from outside of the container for releasing contents in the upper comestible chamber into contents in the lower comestible chamber for producing a liquid comestible product from the powder and the water. The liquid comestible product can be heated/cooled by actuating the plunger to rupture the heating diaphragm.
