Patent ID: 8402963

Claim:
A container for housing and dispensing a liquid comestible product and in situ heating or cooling thereof, comprising: (a) an annular outer housing having an inside surface, an outside surface, an upper threaded neck, an open upper end, and an open lower end; (b) a base rotatably engaged with the annular outer housing lower end; (c) a sealing member disposed within said annular outer housing and further comprising a one or more upper seal projections and a sealing disk which mates against the inside surface of the annular outer housing forming a divided upper comestible chamber for retaining a comestible product and a lower mixing chamber for retaining a comestible liquid; (d) a threaded lid engageable with the upper threaded neck, said lid projecting within the neck to contact the one or more upper seal projections; (e) an inner annular heating shell disposed within said annular outer housing and affixed to said annular outer housing; (f) a liquid water bag disposed within said inner annular heating shell for housing a quantity of water; (g) a heat transfer bag for containing a chemical reactant disposed between said inner annular heating shell and said base; and (h) a cutter carried by said base and disposed so that rotation of said base urges rotation of said cutter into contact with said liquid water bag, wherein engaging the threaded lid with the upper threaded neck and advancing the threaded lid forces the sealing member into contact with the sealing member, thereby disengaging the sealing disk from contact with the inside surface of the annular outer housing and allowing mixing of the contents of the upper comestible chamber and the lower mixing chamber, and wherein rotation of the base relative to the annular outer housing pierces the liquid water bag and allows for release of the contents of said liquid water bag for contact with the contents of said heat transfer bag resulting in the generation of heating or cooling for heating or cooling contents in said comestible mixing chamber.
