SELF-HEATING/COOLING ARRANGEMENT FOR BEVERAGE AND/OR FOOD

摘要

An arrangement for heating or cooling a pre-sealed container for beverage and/or food includes a reaction vessel with a reaction volume in which first and second reactants intermix when desired to change the temperature in the reaction volume. A pre-sealed beverage and/or food container thermally contacts the reaction volume, and has a generally tubular shape with a bottom, and a top with means for opening the container. A lid surrounds, and is sealed to, the top portion of the container, for enclosing part of the reaction volume. Confronting surfaces of the top portion of the container and the lid have respective cooperating, portions shaped in an overall tapering manner, more narrow towards the top of the container, so that downward pressure from the lid towards the container substantially aids in holding the container against a bottom support for the container. A seal is positioned between the confronting surfaces.
