When dispensing carbonated beverages, particularly beers and especially draught stout, it is desirable to obtain a close-knit creamy head. To achieve this a container (1) includes a separate closed hollow insert (5) containing substantially no oxidising gas and means (6) responsive to opening of the container (1) to provide communication between the inside of the insert (5) and beverage (7) contained in the body of the container (1) upon opening it to jet gas from the insert (5) into the beverage (7). The means (6) preferably has the form of a pressure responsive valve. The insert (5) may be arranged so that its internal pressure is increased after the container (1) is sealed or the means (6) may have a different relief pressure when initially inserted into the container (1) from that upon opening the container (1).
