ABSTRACT:
A liquid dispenser for dispensing liquid from a container that includes a pump having an upper fitment connected to a pump tube and hence to a pump tip. The dispenser has upper and lower fitment recesses, structure for closing the lower recess, vertical pressure support wall, and pump lever that collectively constrain the pump tube to a precise operating envelope for improved pump performance and dispenser reliability. The three-section lower fitment recess provides a mechanism to grip or hold in the pump tip, and prevents lateral and longitudinal movement of the pump tip. The lower recess may have a hard interface with the extended shank of such pump tips. The dispenser has a hard, smooth, seamless exterior cover to resist build-up of scum and facilitate cleaning, closely-fitting mating edges and a latching mechanism between the cover and the back plate to resist infiltration of water. The dispenser has a sloping upper exterior surface on the push bar to shed water, an ergonomic depression in the push bar to accept the heel of the user's hand for pumping action, and a bottom edge the back side of which tapers to a small radius to minimize the accumulation of scum deposits resulting from contact with the user's wet palm and fingers.
