ABSTRACT:
A cooling device for a can containing a beverage is proposed, the device having a closure formed in an end panel of the can, the closure protruding inwardly from the end panel. A suitable cooling substance in a compressed form is charged into the closure which is sealed with a cover provided with an operating lever. The operating lever has one end formed into a sharp point against the cover member. The cover can thus be punctured by manipulating the operating lever to form an orifice through the cover member to allow the pressurized cooling substance in the closure to evaporate or to expand through the orifice formed in the cover, so as to absorb heat from the can and thus cool the contents of the can.
