Abstract
This invention relates to the liquid dispensing of toxic and noxious liquids in such a way that accidental contact with the operator is minimized. This dispenser comprises a sealed cylinder, a piston snuggly fitting inside the cylinder, a pivoted handle, which is limited in its movement by an adjustable screw and a buffer, moves the piston relative to the cylinder, an inlet for feeding liquid into the cylinder, a nozzle at one end of the cylinder for dispensing the liquid from the cylinder, and a drainage outlet at the handle end of the cylinder. Various parts of the dispenser are connected by screw fittings so as to aid in the dispenser's assembly and disassembly.
