1. A can (1) containing a pressurized carbonated beverage (8) including having a non-resealable closure (3);

  • the can being characterised by a secondary compartment (4) formed on the lid (2) below the closure (3), by at least one orifice (5) extending between the secondary compartment (4) and the inside of the can (1), and by a liquid (8) held in the secondary compartment (4), the arrangement being such that on opening of the closure (3) the pressure in the secondary compartment (4) is reduced to atmospheric with the result that gas or liquid from the main body of the can (1) is jetted through the at least one orifice (5) into the liquid (8) in the secondary compartment (4) to generate a foam in the secondary compartment (4);

    complete opening or removal of the closure (3) enabling the contents of both the secondary compartment (4) and the remainder of the can (1) to be mixed and dispensed together so that the foam produced in the secondary compartment acts to seed the generation of small bubbles throughout the beverage (8) in the can (1).
