Abstract:
A container for the storage and dispensing of carbonated beverages, said container comprising:a rigid shell having, at its base internal to the shell, a first sculpted surface as herein defined; a bladder, for retaining a liquid, housed within the shell; valve means in communication with the inside of the bladder and the outside of the shell; compression means within the shell but external to the bladder and adapted to apply a continuous force to a piston means; said piston means interposed between the compression means and the bladder, the surface of the piston adjacent the bladder having a shape complementary to the first sculpted surface thus forming a second sculpted surface; wherein, in use, the second sculpted surface of the piston acts on the bladder thereby shaping the bladder according to that surface and, as liquid is dispensed from the bladder via the valve means, the piston is urged by the compression means towards the first sculpted surface at the base of the shell and mates therewith when the liquid is exhausted.
