A rapid refrigeration apparatus and method for beverages having a container (10) with a flexible thin-film aluminum or plastic receptacle (16) secured to an upper end of the container (10) by way of an expansion nut (18). The receptacle (16) has a variable volume and is arranged to be in thermal contact with an internal region of said container. A refrigerant is placed within said receptacle and as the volume of the receptacle decreases during collapse due to evaporation of escaping refrigerant provides cooling of the container's contents.

[ We claim:] [1.] A rapid refrigeration apparatus comprising: a container means comprised of a top and bottom wall sealingly connected to a side wall to define an interior chamber therein, one of said walls having a first aperture means for accessing said interior chamber; a receptacle means disposed within said interior chamber, said receptacle means constructed from a material of nominal thickness having a variable volume containing a refrigerant maintained in a state in which pressure inside said receptacle equals pressure of contents placed outside said receptacle; a second aperture means positioned in one of said walls of said container means enabling atmospheric communication between said receptacle means for controlled evaporation of said refrigerant; wherein said receptacle refrigerant is voluntarily released through said second aperture means thereby causing a rapid lowering of content temperature of said container means.
