Abstract: An appliance for making an aerated beverage comprising a casing (10), a connection (17) carried by said casing for mounting a container (18) of pressurized liquid carbon dioxide, a pivotally mounted shatterproof housing (24) for a bottle of water (29), a nozzle (31) communicating with the connection and extending downwardly within the housing and through a stopper (27) for engaging the neck of the bottle supported within the housing and a safety pressure valve (34) connected to the interior of the bottle when the stopper is engaged in its neck, the housing being axially reciprocable to engage and disengage a latch (47, 48, 49) for the pivotal housing and to unseat the valve (34) at each axial reciprocation.

Abstract: An appliance for making an aerated beverage by introducing carbon dioxide under pressure into a bottle (29) partly filled with water, in which a support member (16) is pivotally mounted by a pivot (15) on the casing (10) and carries the shatterproof housing, (24), which surrounds the bottle, the nozzle (31), the stopper (27) and the container (18) of pressurized liquid carbon dioxide, so that these all pivot with the support member as a pivotal assembly. Such a construction can be made relatively inexpensively.

Abstract: An appliance for making an aerated beverage, in which a container of pressurized liquid carbon dioxide is mounted on a connection in a casing, the casing being mounted thereon, a housing for a bottle partly filled with water, means for supporting the bottle in the housing, a nozzle communicating with the carbon dioxide container and a stopper for engaging in the neck of the bottle. A manually operable valve is provided to allow carbon dioxide to enter the nozzle so that it is dissolved in the water. A displacement body on the nozzle is provided so that when a partly filled bottle is introduced with the nozzle therein, the level of the water rises so that only a small amount of air is left above the water in the bottle, thus reducing the wastage of carbon dioxide.
