Abstract
A device for metering out a paste-like material includes a connector for connecting the mouth of a flexible container to a positive-displacement pump, means for compressing, over a limited area, a bag filled with the paste so that the paste is acted on at this point by shear forces and at the same time squeezed towards the mouth of the bag. A suction pump is located behind the positive-displacement pump. The devices makes it possible to meter highly viscous pastes from flexible bags simply and without interruption, even when the paste includes trapped air.
