A drinking mug or tumbler-like device self equipped to rapidly transform its contents into a congealed, or very low temperature liquid condition comprising an inner container enclosed within a larger outer container that is filled with a water based refrigerant in the space therebetween, and hermetically sealed with a special seal gasket arrangement. In preparation for use, the device in placed in a refrigerator freezer until the refrigerant is solidified. The contents are then poured into the container and cooled as heat is absorbed by the refrigerant through the walls of the inner container. The specially proportioned inner container aids transfer of heat energy to speed cooling of the contents, along with a fabric which aids in the distribution of thermal energy throughout the refrigerant, and also controls the degree of congealment within the beverage, and refrigerant. The refrigerant compartment is specially designed to assist directing of the expansion volume of the frozen refrigerant away from the walls and into an expansion absorber fitted at the bottom of the compartment. The exterior of the device is easily detachable from the remainder of the unit to reduce preparation time in the freezer, and to allow retrofit for altered cooling performance, decorative appeal, and adaptation for outdoor use. The concepts identified above are also applicable in the design of hot cup devices.
