Abstract

The invention relates to an assembly for delivering a paste from a flexible supply packing drum (6) to a dosing device (2). Said packing drum is arranged in a dimensionally stable container (4) and has descending product guidance. The dosing device delivers by means of a low pressure. In addition, a follower plate (7) is arranged on the flexible supply packing drum (6). Said follower plate exerts pressure the supply packing drum (6). An opening (9) is provided in the bottom of the container (4). The container (4) is sealed against the dosing device (2) and the follower plate (7) is sealed against and moveable within the container (4). A low pressure is applied between the container (4, 5) and the flexible supply packing drum (6).

Claims

1. An arrangement for delivering and guiding a paste from a flexible storage container (6) accommodated in a dimensionally stable pot (4) downwards into a dispenser (2) operating by reduced pressure, the flexible storage container (6) being surmounted by a follower plate (7) which applies pressure to the storage container (6) and an opening (9) being present in the base of the pot (4), characterized in that the pot (4) is sealed off from the dispenser (2) and the follower plate (7) is sealed off from the pot (4) and is movable therein and in that a reduced pressure is applied between the pot (4,5) and the flexible storage container (6).

2. An arrangement as claimed in claim 1, characterized in that the edge of the follower plate (7) adjoining the inner wall of the pot (4) is of such a height that the pot (4) is unable to tilt.

3. An arrangement as claimed in claim 1 or 2, characterized in that the reduced pressure is provided by connecting the space between the pot (4,5) and the flexible storage container (6) to the suction side (11) of the injector.
