The invention relates to an assembly for delivering a paste from a flexible supply packing drum to a dosing device. The packing drum is arranged in a dimensionally stable container and has a descending passageway for product guidance. The dosing device draws paste from the packing drum by use of a low pressure. In addition, a follower plate is arranged for positioning on the top of the flexible supply packing drum. An opening is provided in the bottom of the container. The container is sealed against the dosing device, and the follower plate is sealed against and moveable within the container. A low pressure is applied between the container and the flexible supply packing drum for assisting the transfer of paste into the dosing device.

1. An arrangement for delivering a paste from a flexible storage container into a dispenser operating by reduced pressure, the arrangement comprising: the flexible storage container, a dimensionally stable pot, the dispenser, a follower plate, a dispenser neck seal, and a follower plate seal; the flexible storage container being surmounted by the follower plate, which applies pressure to the flexible storage container; the base of the pot defining an opening; the opening and the pot being sealed off from ambient air by the dispenser neck seal; the follower plate being movable along a longitudinal axis of the pot, the follower plate seal extending along the peripheral edge of the follower plate; the pot and the flexible container defining between them a space; the follower plate seal being adapted and configured to seal the space from ambient air; the space being in fluid communication with the reduced pressure by a gap between a neck of the container and an entrance of the dispenser. 2. An arrangement as claimed in claim 1, wherein the follower plate is unable to tilt. 3. An arrangement as claimed in claim 1, wherein the reduced pressure is provided by connecting the space between the pot and the flexible storage container to the suction side of an injector. 4. An arrangement as claimed in claim 2, wherein the reduced pressure is provided by connecting the space between the pot and the flexible storage container to the suction side of an injector.
