A dispensing system has a dispenser pump mounted on top of a container. Product in the container reaches the intake of the dispenser pump through a vertical feed tube which extends down to the container's base. A follower plate fits around the feed tube and lies on top of the product and is slidable along the feed tube while sealing against the container's side wall. The foot of the feed tube interlocks mechanically with the container base, e.g. by an upward projection on the container base which fits into the feed-tube at its foot. A preferred form of the upward projection has a series of radial fins to permit the flow of product and an upwardly tapered region to facilitate installation of the feed tube. By preventing sideways movement of the feed tube the interlock arrangement improves the performance of the follower plate.

[ What is claimed is:] [1.]1. A dispensing system comprising:a container, said container having a side wall and a closed continuous base formed in one piece with the side wall and being adapted to hold a flowable material for dispensing;a dispenser pump mounted at a top of the container to dispense said flowable material, the dispenser pump having an intake to receive said flowable material from the container;a feed tube extending in the container down from the dispenser pump intake to the container base, to convey said flowable material from the container into the dispenser pump intake, the feed tube having a foot adjacent the container base;a follower plate fitting axially slidably around the feed tube and extending out to the container side wall, to follow a surface of the flowable material down the container as dispensing thereof proceeds; andthe feed tube foot and the container base comprising respective interlock portions presenting respective laterally-directed surfaces which overlap axially in a close-fitting interlock engagement to inhibit sideways movement of the feed tube in the container.
