Abstract: 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.

Abstract: A carbonation method and apparatus is described in which carbonation is achieved by forcing carbon dioxide in gaseous form from an atmosphere thereof downwardly into a body of water to be carbonated. This may be achieved by a vaned rotor rotatable about a horizontal axis or other means. The carbon dioxide atmosphere is preferably maintained at a pressure of about 100 psig (6.8 bars). The degree of carbonation may be varied by varying the time for which the carbonation operation is carried on. A flavor concentrate supply means, containing various flavors, is pressurized for the supply of the concentrate utilizing what would otherwise be waste carbon dioxide gas from the carbonation chamber after completion of the carbonation operation.
