System for supplying a substance

Abstract

A system for supplying a liquid or paste-like substance. The system comprises a compressible bag for receiving the substance to be supplied, a supply assembly which forms a supply channel with a corresponding supply mouth for supplying the substance from the bag, and a container. The container has a supporting body comprising at least a supporting plate and a movable presser plate, wherein the supporting body and the presser plate together form a chamber for the incorporation therein of the bag, so that the bag is positioned between the supporting plate and the presser plate. The presser plate can be moved in a pressure direction to the supporting plate to empty the substance from the bag. The supporting body in a region between the supporting plate and the presser plate is provided with a passage for the supply assembly. The supporting body and the supply assembly in addition are provided with guiding means working in concert, such that the supply assembly is movably guided in the pressure direction vis-à-vis the supporting body between a starting position going with the bag in the filled state and a final position which is closer to the supporting plate and goes with the bag in the empty state.
