Patent

CA 2678633

A dispenser includes a housing and a push bar movable between a rest position and an actuated position. A container is retained in the housing and holds a liquid, and a pump is associated with a liquid. The pump is actuated to dispense a dose of the liquid, when the push bar is moved from its rest position to its actuated position. A dispensing tube includes an inlet associated with the pump, an outlet associated with the push bar, and a bellows portion between the inlet and the outlet. Upon moving the push bar from its rest position to its actuated position, the bellows portion is collapsed from an expanded volume to a compressed volume, and the outlet of the dispensing tube moves with the push bar. Upon return of the push bar from the actuated position to the rest position, the bellows portion expands from the compressed volume to the expanded volume, and draws liquid at the tip of the dispensing tube into the dispensing tube to reduce or eliminate dripping. Pinch members are optionally employed to pinch the dispensing tube closed to prevent product dripping therefrom when the dispenser is not in use.
