ABSTRACT OF THE DISCLOSURE An appliance for making an aerated beverage. The apparatus comprises a casing and means for mounting a container of pressurized carbon dioxide in the casing. A manually operable valve controls the outflow of carbon dioxide from the container. A nozzle is connected to the manually operable valve to receive carbon dioxide from the valve. Means is provided for mounting a bottle containing water, so that the nozzle is immersed in the water in the bottle. A flexible diaphragm surrounds the upper end of the nozzle and a stopper is carried by the diaphragm and closes the neck of the bottle when so mounted. A space is formed above the diaphragm and communicates with the interior of the bottle when mounted with the stopper in its neck. The upwardly projected area of the diaphragm forms a wall of the space being 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. An overpressure safety valve communicates with the space above the diaphragm.
