A dispensing device for dispensing a measured quantity of a concentrated cleansing liquid into a spray bottle or any other suitable receptacle, is provided with means for pumping the measured quantity of the liquid from a source into a holding reservoir. The dispensing device includes inhibiting means for preventing the interruption of a priming stroke as the liquid is pumped from the source into the reservoir and for preventing the interruption of a delivery stroke as the liquid is pumped from the reservoir to the receptacle. The inhibiting means includes a pivotable lever having an arcuate rib engaged by a pair of locking members arranged to engage opposite tracks of the arcuate rib.

Dispensing device

A manually operated dispenser for dispensing single shots of liquid with a built-in extended delay between each manually dispensed shot is described. The dispenser contains a manually operated pump for withdrawing a single shot of liquid from the reservoir of liquid, an outlet through which the pump dispenses the single shot and a reciprocal piston and cylinder assembly on the pump. The piston is ready to dispense the single shot of liquid into the outlet when in a retracted position. A plunger which is biased to move away from the piston manually moves the piston to dispense the shot. A detent is provided for locking the plunger in an outward position. A piston spring is loaded in a manner such that when the piston is moved to a retracted position the detent is disengaged and the relative movement of the piston from the extended position to the retracted position defines a built in extended delay between dispensed shots of liquid.
