ABSTRACT:
A liquid dispenser includes a conventional syringe of the type having a piston, a piston rod, an actuating knob disposed in a cylinder, and a needle extending from the cylinder. The invention consists of a needle assembly therefor which includes a cap, a sleeve slidable on the needle and a retainer cap interconnecting the two. The cap is used for closing the needle to preserve the liquid and prevent spillage. The needle is provided with an inner coupler which may consist of two slightly spaced beads fixed to the needle near the end thereof. There is also provided an outer coupler into which may be fitted an extension tube by means of another inner coupler of the same construction as the first one. The inner coupler may be so mounted on the needle that its extension tube is housed in the inner needle, or it may be reversed so that the extension tube extends from the inner needle to extend the point at which the liquid is dispensed.
