ABSTRACT:
An appliance for making an aerated beverage, e.g. for domestic use, comprising a casing in which is mounted a pressurized container of carbon dioxide which is controlled by a manually operable valve, the operation of which is worked by a finger actuable lever. A nozzle is connected to the valve to receive carbon dioxide therefrom and inject it into water in a bottle when the bottle is mounted with the nozzle immersed in the water. A flexible diaphragm surrounds the upper end of the nozzle and carries a stopper which closes the neck of the bottle when so mounted. A space is formed above the diaphragm which communicates with the interior of the bottle when mounted with the stopper in its neck, and the upwardly projected area of the diaphragm forming the lower wall of the space is greater than the downwardly projected area of the stopper, whereby the pressure of the carbon dioxide urges the stopper into engagement with the neck of the bottle, and an overpressure safety valve is provided in communication with the space above the diaphragm.
