A container 1 is combined with a pump designed to generate a vacuum inside the container so that material can be sucked into it. The container has a partition 18. A space 19 on one side of the partition 18 communicates with on the one hand the pump 2 and on the other hand another container space 21 on the other side of the partition. Air from the container space 21, which is intended to contain solid or liquid material sucked in, will therefore pass from the latter space to the pump 2 via the former space which takes on the nature of a separator of solid or liquid impurities in that the air flowing into the separator space is allowed to expand and thus has reduced speed. <IMAGE> |
