ABSTRACT:
A self-contained cooling device for use in a container such as a food container to cool the contents of the container at any desired time includes a reservoir containing pressurized fluid. The reservoir is secured to the inside of the container to form an expansion chamber between the reservoir and the container. A tube communicates with the reservoir and extends into the expansion chamber, the tube normally being closed to prevent escape of pressurized fluid from the reservoir. When it is desired to cool the contents of the container the tube is opened so that pressurized fluid from the reservoir expands into the expansion chamber thereby cooling the expansion chamber, reservoir, and contents of the container. Embodiments of the device shown specifically are adapted to be used with commonly used "pop-top" beverage cans and in such instance the tube extends to securement with the tab used to operate the "pop-top" or with a separate tab, and operation of the tab causes opening of the tube in the expansion chamber. The device may be secured to the end of the normal "pop-top" can and the reservoir is generally conical in configuration, so can easily be inserted into the filled beverage can by high speed canning equipment as the end is placed on the can and sealed. A further embodiment of the device is shown specifically adapted for use and reuse in an insulated food container.
