  • Patent number: 6302304
    Abstract: 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.

  • Patent number: 4838460
    Abstract: A dispenser for lotions, creams and the like has an annular collar in the form of a rotatable cam ring which may be turned to rock an actuator toward a dispensing, open position or toward a closed, non-dispending position. The cam ring has cam tracks that support the actuator when in its open, dispensing position so that finger pressure exerted on the actuator to pump products from the dispenser does not inadvertently rock the actuator toward its closed position. In preferred forms of the invention, a wall section formed as part of a shroud surrounding the actuator is yieldably biased in an inwardly direction, and snaps over the outlet of the actuator to close the outlet channel once the actuator has been pivoted toward its closed, non-dispensing position.
