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.

A container for holding freezable liquid, said container comprising: a plastic shell adapted to receive and contain the freezable liquid, said shell presenting a face surface and an opposed back surface and a pair of opposed side surfaces presenting planar areas smaller than the face and back surfaces; a pair of spaced apart plugs projecting from said face surface; a pair of recesses in said back surface in contraposition to and aligned with said plugs and having sizes and shapes complemental to the plugs; a pair of spaced apart plugs projecting from one of said side surfaces and having the same size, shape and spacing as the plugs on said face surface; and a pair of recesses in the other of said side surfaces in contraposition to and aligned with the plugs on said one side surface and having the same size, shape and spacing as the recesses on said back surface, whereby a plurality of containers can be joined with the plugs on the face surface of each container fitting in the recesses in said back surface or said other side surface of an adjacent container and with the plugs on said one side surface of each container fitting in the recesses in said back surface or said other side surface of an adjacent container, thereby permitting adjacent containers to be arranged face surface against back surface, face surface against side surface, side surface against back surface or side surface against side surface.
