Abstract
Refrigeration apparatus comprising a cold storage compartment, accessible from the outside, and provided internally with a sealed container adapted to accommodate a flexible and compressible receptacle holding a beverage; there are provided pneumatic or air-compression means to generate a selectively controllable pneumatic pressure inside said container, but outside said flexible receptacle, and said sealed container is capable of being opened from the outside by means of a closure applied on a face thereof, wherein said closure is provided with a through-aperture, through which there extends a drawing-off conduit. Whenever a need arises for beverage to be drawn off the receptacle, a pressure increase is triggered inside the sealed container, and said pressure increase will act upon the walls of the internal receptacle so that the latter is caused to collapse and reduce its volume, thereby causing the beverage to be ejected therefrom and, therefore, drawn off.
