LT7189B - Reusable beverage cooling cup with integrated co2 cooling system - Google Patents

Abstract

The present invention relates to a reusable thermally insulated cup containing a capsule with compressed carbon dioxide (CO2), which is used as a cooling medium for rapidly cooling beverages without an external energy source. The cup includes a body (1) made of stainless steel, aluminium or plastic, an inner drinking chamber (3) made of food-grade plastic, where a cavity (4) is formed between the inner walls of the cup body (1) and the inner drinking chamber (3) for the circulation of CO2 gas, a lid (5) with a drinking hole made of food-grade plastic, a holder (7) at the bottom of the cup with a compressed CO2 gas capsule (8) placed therein, a valve (9) for regulating the pressure of CO2 gas exiting from the capsule (8), a distribution channel (10) for distributing the CO2 gas exiting from the capsule (8) in the cavity (4), a rotating CO2 gas capsule (8) activation mechanism (10) for injecting the CO2 gas from the capsule (8) into the cavity (4), having two different control modes - cooling and freezing. Additionally, the cup may have a handle (2), an LCD display (12) mounted on the outer surface of the cup body (1), connected to a beverage temperature sensor in the inner beverage chamber (3) and a CO2 gas capsule (8), for visualizing both the temperature of the beverage itself in the chamber (3) and the remaining CO2 gas in the capsule (8).
