Abstract
A carbonated beverage container (10, 35, 40) including a hollow insert (1, 20). The insert (1, 20) has one one-way valve (7, 29, 31, 32) and one orifice (6, 28, 33, 34), one of which is arranged to allow gas from a headspace above beverage (11) to enter the insert (1, 20), and the other is arranged to jet gas from inside the insert (1, 20) into the beverage (11) upon opening the container (10, 35, 40). The 20 gas jetting into the beverage (11) causes nucleation of fine bubbles in the beverage (11) which separate out to form a close-knit creamy head.
