This invention relates to an improved liquid soap dispenser of the type ones which are commonly located in public washrooms and the like. These kind of soap dispensers include a frame, a manually operable pump mounted on the frame and a reservoir operatively connected to the pump for supplying soap to be dispensed. The soap is generally dispensed when a tube, connected to the reservoir, is squeezed. The current invention provides simple and efficient ways for controlling the quantity of soap dispensed from such liquid soap dispenser. As such, the amount of pressure provided to the tube is varied, thereby varying the amount of soap dispensed. Preferably, the pump includes a handle and a wall portion facing each other on opposite sides of the tube. The wall member is pivotable about a pivot point, so that by increasing the angle between the wall member and the tube, the handle does not compress the tube as much and thus less soap is dispensed.

[ What is claimed is:] [1.] In a liquid soap dispenser having a frame, a manually operable pumping means mounted on the frame and a reservoir operatively connected to said pumping means for supplying soap to be dispensed to said pumping means, the pumping means comprising:a hollow squeeze tube having a longitudinal axis, a first end connected to said reservoir and a second open end for dispensing the soap, the second end including a valve means for permitting soap to flow but preventing air from entering the tube;a wall member extending substantially parallel to said axis and proximate said tube;a manually operable pressing means facing the wall member and extending proximate the tube on the opposite side of the wall member, the pressing means and the wall member co-operating together to compress said tube when said pressing means is operated, said compression opening said valve means and subsequently squeezing the soap out of said tube and dispensing it therefrom; improvement wherein the wall member includes means for adjusting a distance between said wall member and said pressing means with respect to said axis whereby a volume of said soap dispensed is modified.
