FIELD: food industry, particularly beverage storage and cooling devices.
SUBSTANCE: vessel comprises metal inner cup filled with beverage and put into outer cup. Outer cup is formed of low-conductive material and filled with water. Upper surfaces of inner and outer cups are aligned with each other. Outer cup bottom may be easily ruptured under additional mechanical action application. Additional vessel is mechanically connected to lower surface of outer cup by means of threaded connection. The additional vessel is filled with salt having low cryohydrate solution temperature and has spikes at base thereof. Additional vessel may move towards lower surface of outer cup along threaded connection to create air-tight seal. Spikes have lengths enough for outer cup bottom rupture as said air-tight seal is created.
EFFECT: increased beverage cooling rate immediately before beverage consumption.
