    • A device for chilling the contents of a beverage container (10, 74) comprising a shell, the interior of which is adapted to accommodate the container (10, 74) the contents of which are to be chilled, and the wall of which comprises an annular reservoir (16, 70) for liquified refrigerant gas under pressure, which surrounds the container. The reservoir (16, 70) is openable at (30, 76) to permit the liquefied refrigerant to escape therefrom and create a cooling effect on the wall of the container (10, 74), consequent on the change of phase from liquid to gas, and expansion of the gas, to chill the container (10, 74) and its contents. The outer surface of the shell is formed with a heat insulating layer (24, 78) so that the cooling effect is preferentially directed towards the interior. The reservoir (16, 70) may be vented at the top of the bottom or through a plurality of apertures (106, 108) distributed around the interior of the shell. The venting apertures (106, 108) are small so as to restrict the flow of refrigerant and cause the cooling effect to occur over a period time. In a preferred embodiment the reservoir comprises a coiled tube (16, 70) within which the container (10, 74) is a snug fit. A rotatable base (22, 72) serves to close off the underside of the shell and provides a mechanism for venting the reservoir (16, 70).
