An outer container constructed of a non-metallic material and an inner container constructed of metal permanently secured to said outer container. The inner container houses a material which when activated alters the temperature of food or beverage housed within the outer container and in contact with an outer surface of the inner container. Preferably, the outer container is constructed of food grade glass or plastic or paper products having a waterproof interior and the inner container is permanently affixed thereto by a threaded plug or a washer like member welded thereto respectively.

Non-metallic food or beverage container having a heat exchange unit

A heat exchange unit for use in containers for cooling a food or beverage. The heat exchange unit includes inner end outer vessels with inner vessel having a plurality of thermally conductive discs in thermally conductive contact with an inner surface thereof. An adsorbent material is disposed between adjacent discs is compacted between them to provide maximum adsorbent material per unit volume. The outer surface of the inner vessel defines a plurality of grooves and is in thermally conductive contact with the inner surface of the outer vessel. The grooves provide flow paths for a gas such as carbon dioxide which is adsorbed onto the adsorbent material to flow and exit the heat exchange unit and to carry with it, the heat contained in the food or beverage, thereby lowering its temperatures.

Heat exchanger unit with conductive discs

A heat exchange unit and a beverage or food container including a heat exchange unit therein. The heat exchange unit includes a vessel having a plurality of thermally conductive discs with a layer of compacted adsorbent material such as carbon particles disposed between adjacent discs. The periphery of the discs are in thermally conductive contact with the inner surface of the vessel and each discs has at least one surface which defines a plurality of radially extending grooves terminating at the periphery to define a preferential flow path for gas under pressure to travel along the inner surface of the vessel wall. The periphery of the discs also define a plurality of notches, one at each groove terminal, to enhance the preferential flow path.
