Abstract (en)
[origin: EP0176135A2] A liquid soap dispensing system includes a closed soap reservoir having a manually actuated pumping mechanism located below and in fluid communication with the reservoir. The pumping mechanism basically comprises a cylindrical bowl having an open end defined by a continuous side wall and a moveable, substantially rigid closed end that is attached about its periphery to the bowl's side wall. The dispenser also includes a hand-pulled lever having two moving ends that pivot around a pivot pin - one end extending outside the dispenser for easy grasping thereof by the user with the other end being in sliding contact with the outer surface of the bowl's rigid end. In operation, a discrete quantity of liquid soap flows from the upper reservoir through a one-way valve and fills the bowl's interior cavity. When the lever's grasping end is pulled, the lever's bulb-contacting end pushes the bowl's rigid end up within the cross-section defined by the bowl's side wall toward the bowl's open end and forces the soap contained therein out through a discharge conduit and into the user's hand. When the lever is released, the bowl expands and draws another discrete charge of soap from the upper reservoir.
