DISPOSABLE BEVERAGE STORAGE VESSEL TO BE RAPIDLY COOLED Russian patent published in 2008 - IPC B65D81/34 B65D25/08 F25D5/02 

FIELD: beverage container adapted for beverage cooling.

SUBSTANCE: vessel has inner case 1 filled with beverage and placed inside outer case 2 formed of low-conductive material. Upper planes of inner 1 and outer 2 cases are in single level. Outer case 2 is separated into two isolated chambers 6, 7 with rupturable partition 5. Lower chamber 6 is filled with water 8. Upper chamber 7 is separated into several cavities with rupturable partitions 9. The cavities are filled with salt having low cryohydric solution temperature. Upper chamber 7 of outer case 2 has corrugated side walls. Upper chamber 7 of outer case 2 may perform free rotation about inner case 1. Upper base of upper chamber 7 has spike 12, which ruptures partition 5 between upper 7 and lower 6 chambers of outer case as small pressure is applied to upper vessel surface. As upper chamber 7 rotates relatively inner case the spike 12 pierces through partitions 9 created between upper chamber 7 cavities.

EFFECT: possibility of selective rapid or slow beverage cooling on user's demands.
