Patent ID: 8602267

Claim:
A device for discharge of liquid or substantially liquid products from a compressible container made of flexible material which container is placeable in an outer container and is compressible therein by a compression device in order to feed product out therefrom through a nozzle, wherein a movable compression means which forms part of the compression device is disposed on a piston or equivalent adapted to being subjected to movements in a portioning direction (P 3 ) so that the movable compression means squeezes the container in the outer container, and that the piston with its movable compression means can perform a return movement in a return direction (P 4 ) which is opposite to the portioning direction (P 3 ), characterised in that the piston is adapted to being subjected to movements in the return direction (P 4 ) by the movable compression means being pressed down by the weight of the container and the product present therein.
