Abstract: A container for housing and producing a liquid comestible product and in situ heating or cooling thereof is constructed for rotation of the lid to release a comestible powder into water. Rotation of the base causes release of liquid to be initiated for allowing mixing of the comestible powder/water blend.

Abstract: A container for housing and producing a liquid comestible product and in situ heating or cooling thereof is constructed for rotation of the lid to release a comestible powder into water. Rotation of the base causes a chemical reaction to be initiated for heating or cooling the comestible powder/water blend.

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.
