Abstract

A dispensing system for flowable material comprises a container having a cover 2 through which is mounted a pump 8. A stiff feed tube 3 extends from the pump 8 down to the foot of the container. A follower plate 5 which fits around the feed tube 3 and is slidable down inside the container, lies on top of the material M in the container and assists in clearing material from the container as dispensing proceeds. In order to help prime the pump 8 and avoid the follower plate 5 losing contact with the surface of the material M after container filling, e.g. on shrinkage of a warmed material, a spacer 100 is fitted between the top of the container and the follower plate 5 so that the follower plate 5 is forced down in the container on assembly. This also urges material up inside the feed tube 3 to assist pump priming.
