The container (1) has a cylindrical lower sidewall (11) and a floor (30) which define a lower beverage chamber (2), and a cylindrical upper sidewall (9) and a top wall (31) which define an upper pressurized gas chamber (3). A lower protective ring (7) is fitted around the floor, while an upper protective ring (8) is fitted around the top wall, to facilitate stacking of the containers. A partition (10), which has an outer edge welded to the upper sidewall lower edge and the lower sidewall top edge, is set between the beverage chamber and the pressurized gas chamber. A valve assembly (4), which includes a riser tube (32) that extends through the partition into the beverage chamber, is installed at the top wall. A tap (25) is connected to the valve assembly. |
