Abstract
Abstract An applicator syringe preferably made of a plastics material and intended for one time use only, said syringe comprising a plunger and a body member in which the piston is arranged for axial movement, and further comprising a pivotable nozzle which in its starting position extends concentrically with said body member and said plunger, wherein the body member and the nozzle are mutually joined together by means of a bellows-like conical junction member which is located concentrically with the body member and the nozzle and is arranged to enable said nozzle to be manually pivoted a repeated number of times between its starting positions and stable positions in all directions relative to said starting position.

Claim 1
Independent Claim
213 words
A disposable applicator syringe of plastics for dispensing pastes, comprising a tubular body member, a plunger fitted in said body member and axially slidable therein, a pivotable tubular nozzle of a smaller cross sectional area than the body member and having a neutral position with its axis substantially in axial alignment with the common axis of the plunger and the body member, a frustoconical junction member connecting the inner end of the nozzle with the body member, said junction member having a number of folds of progressively reduced diameter from the body member to said inner end and mutually concentric and concentric with the plunger, with the body member and with the nozzle in the neutral position thereof, the mutual spacing and the dimensions of said folds being chosen to enable the manual tilting of the nozzle to any stable inclined position relative to the body member, and said nozzle remaining in any selected inclined position without any manual force acting thereupon, and said junction member permitting the repeated manual transfer of said nozzle from any inclined position to another inclined position and to its neutral position, thus enabling the use of the syringe for dispensing paste with its nozzle located in any number of selected angular positions relative to the body member.
