US Patent 7484383 Cooling pitcher

A pitcher for keeping beverages cooled for protracted periods, having a pitcher lining and a pitcher wall sealingly attached to form a cavity there between. A freezable substance is disposed within the cavity. The cavity extends continuously between the bottom walls of the pitcher lining and the pitcher wall allowing for complete cooling through the floor area of the pitcher. In an alternate embodiment an insulating layer is provided between the freezable substance and the inner surface of the sidewalls and bottom wall of the pitcher shell. The insulating layer further retards warming and reduces condensation.
