Claims20
A pressurizing device, comprising a gas container having a filling opening, the gas container comprising an amount of dry ice inserted through the filling opening, wherein the filling opening is closed, such that the dry ice is allowed to sublimate, wherein a pressure regulator is provided on the gas container and wherein the pressure regulator comprises a pressure regulating chamber comprising a gas at a reference pressure, for opening and closing a gas valve of the gas container to a surroundings of the gas valve, depending on a pressure prevailing in said surroundings the pressure regulating chamber comprising a wall part that opens and closes the gas valve in response to pressure in a beverage container.
A pressurizing device, comprising a gas container having a filling opening, the gas container comprising an amount of dry ice inserted through the filling opening, wherein the filling opening is closed, such that the dry ice is allowed to sublimate, wherein a pressure regulator is provided on the gas container, and wherein the pressure regulator comprises a pressure regulating chamber comprising a gas at a reference pressure, for opening and closing a gas valve of the gas container to a surrounding of the gas valve, depending on a pressure prevailing in the surrounding, the pressure regulating chamber comprising a wall part that opens and closes the gas valve in response to pressure in a beverage container, wherein the gas container is made of plastic.
A pressurizing device, comprising a gas container having a filling opening, the gas container comprising an amount of dry ice inserted through the filling opening, wherein the filling opening is closed, such that the dry ice is allowed to sublimate, wherein a pressure regulator is provided on the gas container and wherein the pressure regulator comprises a pressure regulating chamber comprising a gas at a reference pressure, for opening and closing a gas valve of the gas container to a surroundings of the gas valve, depending on a pressure prevailing in said surroundings, wherein the pressure regulating chamber is part of a dispensing device coupled to or provided in a beverage container.
