ABSTRACT:
Method and apparatus for dispensing carbonated liquids into a container under counterpressure. The introduction of liquid under a filling pressure into a container that is in a sealing position with a filling element is effected during a filling phase that follows pressurizing of the container. Return gas displaced by incoming liquid is at least briefly withdrawn from the container via a return gas passage of the filling element. After termination of the filling phase, with the container still in a sealing position with the filling element, first a pre-relief of pressure in the container to a pre-relief pressure is effected, and subsequently a relief to atmospheric pressure is effected. The pre-relief pressure is regulated in such a way to a pressure that is between atmospheric pressure and the saturation pressure of the liquid, that during the pre-relief phase it is still just possible for released carbon dioxide to rise in the dispensed liquid without there occurring during relief to atmospheric pressure an undesired escape of liquid from a filled container as a result of foaming of the liquid.
