CONTAINER FOR DISPENSING CARBONATED LIQUIDS A container, such as a soda siphon, comprises a vessel (2) of blow-moulded plastics material, such as PET. A valve assembly (20), similar to those commonly used with aerosol containers, is received in a neck (6) of the vessel (2). A dispensing head (8) is fitted to the neck (6) over the valve assembly (20). The head (8) has an actuating element (28) which fits over an outlet tube (24) of the valve assembly (20). The actuating element (28) is hinged (at 34) to the rest of the dispensing head (8) and has a passageway (32) which communicates with an outlet nozzle (12). Depression of the actuating element (28) causes the valve to open, and the carbonated liquid flows through the outlet tube (24), the passageway (32) and the outlet nozzle (12). The construction of the container means that its components can be made economically, so that at least the vessel (2) and the valve assembly (28) (and possibly also the dispensing head (8) may be disposable when the contents have been used.
