SINGLE SHOT LIQUID DISPENSER

摘要

A manually operated dispenser for dispensing single shots of liquid with a built-in extended delay between each manually dispensed shot comprises: i) a reservoir (4) of liquid to be dispensed; ii) a manually operated pump for withdrawing a single shot of liquid from the reservoir (4) of liquid; iii) an outlet (3) through which the pump dispenses a single shot of liquid; iv) the pump having a reciprocal piston (8) and cylinder (6) assembly for relative movement, where the piston (8) in a retracted position is ready to dispense a single shot of liquid into the outlet; v) a plunger (2) for manually moving the piston (8) to an extended position to dispense a single shot of liquid from the cylinder (6) and into the outlet (3); the plunger (2) being biased to move away from the piston (8) and to its outward ready-to-dispense position; vi) a detent for locking said plunger (2) in said outward position; vii) the piston (8) spring loaded to move the piston (8) to said retracted position whereby movement of the piston (8) to the retracted position disengages the detent, the relative movement of the piston (8) from the extended position to said retracted position defining the built-in extended delay between dispensed shots of liquid.
