Abstract

A tip cap for a syringe that limits contact between the syringe and a needle tip, wherein the needle tip penetrates the tip cap to one of dispense medication out of the syringe and draw medication into of the syringe. The syringe includes a luer cone extending from a barrel of the syringe. The tip cap includes a penetration wall and a generally cylindrical sleeve extending generally perpendicularly from the penetration wall adjacent a periphery of the penetration wall. The cylindrical sleeve includes a radially, inwardly extending locating shoulder on an inner surface that is positioned a predetermined distance from the penetration wall. The locating shoulder engages an end of the luer cone in an operating position. The penetration wall, cylindrical sleeve and luer cone define a receiving space within which the needle tip is positionable.

Claims

1. A tip cap for a syringe that limits contact between the syringe and a needle tip wherein the needle tip penetrates the tip cap to one of dispense medication our of the syringe and draw medication into the syringe, the syringe including a luer cone extending from a barrel, the tip cap comprising:

a penetration wall; and

a generally cylindrical sleeve extending generally perpendicularly from the penetration wall adjacent a periphery of the penetration wall, the cylindrical sleeve including a radially inwardly extending locating shoulder on an inner surface located a predetermined distance from the penetration wall, the locating shoulder engaging an end of the luer cone in an operating position, the penetration wall, cylindrical sleeve and luer cone defining a receiving space within which the needle tip is positionable.

2. The tip cap of claim 1 wherein the tip cap is constructed of a self-healing, polymeric material.

3. The tip cap of claim 1 wherein the cylindrical sleeve includes a tip mouth, the tip mouth contacting a syringe luer lock which is mounted to the luer cone in the operating position, the contact between the tip mouth and the luer lock further positioning the tip cap relative to the end of the luer cone.

4. The tip cap of claim 1 wherein an inner surface of the cylindrical sleeve on an engaging portion of the sleeve tapers away from a connector axis.

5. The tip cap of claim 1 wherein the engaging portion is force fit onto the luer cone.
