<p>A system for dispensing a substance comprises an axially compressible container (2) for holding a stock of substance. The container has a tubular, dimensionally stable wall which, at one end has a dispensing part (6) with a dispensing passage (7) and at the other end has a closed end (10) which is integral with the wall. The system comprises a device (1) for the metered dispensing of the substance. The device comprises a support (3) with a retaining member (9) for the dispensing part of the container. The device comprises a pressured-exerting member (11) which can be displaced in the axial direction and has a pressure-exerting side (12) which is designed to act on the closed end of the container. The device has drive means for the pressure-exerting member. Substance is dispensed by axial compression of the container under the influence of axial displacement of the pressure-exerting member in the pressure direction. Furthermore, the system has a valve (8) for opening the closing dispensing passage of the container.</p> |
