Abstract
An improved pump tip for a fluid dispenser system using a pump tube, such as common hand soap dispensers, the improvement being a longer pump tip with a longitudinally-extended exterior surface that works with a correspondingly shorter pump tube. The longer exterior surface enables the pump tip to be installed directly into the lower tube locator recess of existing dispensers in close fit and direct contact with the vertical structural wall of the recess, thereby providing a pump tube lower end termination with improved security, rigidity and lateral support of the tip and tube, greater security for the exposed pump tip nozzle, and enabling use of shorter pump tubes of larger diameter without need for a necked-down lower end.
