Abstract
An apparatus (10) is provided for dispensing a flowable product from a collapsible container (12) comprising an air-tight cavity (14) and an opening (16). The apparatus (10) includes a reservoir (18) comprising a chamber (20) for storing flowable product, the chamber (20) comprising a product inlet (22) for receiving flowable product delivered from the air-tight cavity (14) of a connected collapsible container (12) through the opening (16) thereof, and a product outlet (24) for the flowable product. A piston (46) is positioned inside the chamber (30) and is movable to vary the volume of the chamber (30), for example between a first position defining a maximum chamber volume and a second position defining a minimum chamber volume.
