Apparatus for making flavored carbonated beverages includes a carbonator (2) and concentrate supply (4). The latter includes a metering chamber (24) so that metered quantities of concentrate are supplied for making each drink. Concentrate is drawn from a supply bottle (6) into the metering chamber (24) by creating a reduced pressure therein with the aid of a venturi (20) through which carbon dioxide gas under pressure is supplied. The gas from the venturi (20) is directed downwardly into the upper part of the concentrate bottle which includes a baffle structure (48) which prevents this gas impinging directly on the surface of the concentrate and which is so arranged that the gas entering the bottle (6) passes to a gas outlet (72) route only via the space above the concentrate, so that unwanted discharge of concentrate through the outlet route is prevented. |
