A METHOD OF FILLING A DISPENSING SYSTEM AND A DISPENSING SYSTEM

摘要

A method of filling a dispensing system and a dispensing system for flowable material, consisting of a container (1) through the cover (2) of which is mounted a pump (8). A stiff feed tube (3) extends from the pump down to the foot of the container (1). A follower plate (5) fits around the feed tube (3) and is slidable down inside the container, lying on top of the material (M) in the container, to assist complete clearance of material from the container as dispensing proceeds. In order to help prime the pump and avoid the follower plate (5) losing contact with the material surface 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.
