ABSTRACT:
A combination drinking bottle and internal cooling cartridge comprises a cooling cartridge having a top surface and a bottom surface, with a tubulate side wall extending between the top surface and the bottom surface and having a plurality of longitudinal protrusions, each adjacent pair of longitudinal protrusions being separated by a longitudinally extending concave surface. A refrigerant is sealed within an interior cavity formed by the side wall and top and bottom surfaces of the cartridge. The drinking bottle has an interior cavity for containing a quantity of a beverage and the cooling cartridge, which are inserted through a tubulate mouth into the interior cavity of the bottle. The interior cavity also provides lateral support from its side walls to maintain the cooling cartridge in a substantially vertical orientation within the bottle.
