Abstract
A can cooling device that includes a beverage can insulating sleeve, a cylindrical flexible bellows attached to the bottom of the sleeve and a bottom plate. A chemically activated cooling cartridge resides within the flexible bellows A cartridge push plate and compression spring reside within the bellows directly under the cooling cartridge. The cooling cartridge includes an outer flexible enclosure that houses a powder, an inner flexible enclosure containing a liquid, and a rigid plate with upwardly directed attached prongs. When a user presses down on the beverage can, the cooling cartridge is compressed causing the upwardly directed prongs to impale the liquid holding flexible inner enclosure and causing the liquid to mix with the powder causing an endothermic cooling reaction causing the beverage can inside the insulating sleeve to be cooled in relation to the surrounding outside temperature.
