A container (8) for storing and dispensing carbonated beverages, including a housing (10) having a sculpted base surface (30), a storage bladder (12), a dispensing valve, compression means (18) within the housing to apply a continuous force to a piston (16) between the compression means and the bladder, the piston having a shape (24) complementary to the sculpted surface, whereby, as liquid is drawn from the bladder via the valve the liquid is exhausted by the piston mating with the first sculpted surface. Also a retainer assembly (14) including a cap to seal an externally threaded container outlet, the cap having a base wall and peripheral skirt carrying an internal thread which engages with an external thread on the outlet, a spigot having an axial bore, being frangibly connected to extend from the base wall within the cap coaxially with the skirt, the spigot portion having means formed on its outside wall to engage the outlet bore, whereby selective screwing movement of the cap causes rupture of the frangible connection so that the spigot is retained in the outlet bore.
