Abstract
A container filled with a freezable liquid for use in refrigerating or temporarily cooling purposes. The container of the invention is generally rectangular and has two plugs each on its face and one side. Opposite these plugs and in contra position to the plugs, on the back and other side of the container, are corresponding recesses. The recesses and plugs are formed in order that the plugs of one container fit into the recesses of a like container, thus allowing the containers to be fastened together. Thus, when filled with freezable liquid and frozen, two or more containers may be connected, at either their sides or face-to-back, to form blocks of frozen containers. In addition to the advantages of using containers filled with freezable liquid over using water-ice as a coolant, which advantages have been found in the prior art, use of blocks of the frozen containers of the present invention provides longer lasting cooling capability and the convenience of the cooling medium being adaptable to the size and shape of the cooling compartment.
