Zusammenfassung:	Cooling devices 2, 4 for cans containing beverages are disclosed in which, either a closure member 2a is integrally formed with an end panel 10 of the can 1, or a closure member (40) is separately formed into a part annular loop shape that is capable of detachably engaging the outer surface of the can 1. A suitable cooling substance 22, preferably in a compressed form, is charged in the closure member 2a, (40) which is sealed with a detachable sealing member 3, (44). The sealing member can be removed to allow the pressurised coolant to evaporate or expand, so as to absorb heat from the can and thus cool the content of the can.
