ABSTRACT:
A device for dispensing corrosive liquids accurately and without spilling can be held in one hand while the other hand holds a vessel into which liquid is dispensed. The device has a tubular barrel with a thumb stop at a top end and a cap at a bottom end for connection to a liquid container. A hand grip fits over the barrel and is slidable thereon with a connection link to a plunger slidable within a cavity in the barrel. A liquid intake tube extends down from the base of the cavity in the barrel, through the cap, into the liquid container and has a first non-return valve therein, such that sliding movement of the hand grip upwards on the barrel draws liquid through the intake tube into the cavity, and a liquid dispensing tube connected to the cavity, with a second non-return valve therein, such that sliding movement of the hand grip downwards on the barrel dispenses liquid from the cavity through the dispensing tube.
