Abstract:
A rapid refrigeration apparatus comprising:a container having a container upper end, a container wall with a container opening in said container upper end bordered by a container rim;a beverage retaining vessel extending within said container defining a substantially annular refrigerant chamber between said container and said vessel containing a liquified refrigerant with refrigerant vapor, and said vessel containing flowable vessel contents, said vessel being sized to fit at least partly through said container opening, said vessel comprising a vessel rim secured relative to said container rim, and a vessel wall comprising at least one reversible bulge;lid means sealingly secured to said container rim and comprising lid opener means for releasing said vessel contents from said vessel and container for consumption; said lid opener means comprising a lid opener means activation means for voluntarily opening said lid opener means at a selected moment in time subsequent to refrigerant release;and refrigerant release means for releasing said refrigerant from said annular chamber; said refrigerant release means comprising a refrigerant release means activation means for voluntarily opening said refrigerant release means at a selected moment in time, thereby causing said refrigerant to boil into refrigerant vapor and escape into the atmosphere surrounding said apparatus, thereby cooling the vessel contents.
