<p>A carbonated beverage container (10, 35, 40) including a hollow insert (1, 20) which floats on the beverage (11). The insert (1, 20) has two one-way valves (6, 7, 28, 29), one (6, 28) of which allows gas from a headspace above the beverage (11) to enter the insert (1, 20), the other (7, 29) allowing gas from the insert (1, 20) to be jetted into the beverage (11) upon opening the container (10, 35, 40). This jet of gas into the beverage (11) causes shear, and the liberation of gas bubbles which form a close-knit creamy head on the beverage (11) once dispensed.</p> |
