Abstract: A fluid coupler for connecting two devices in locked fluid communication is provided which includes a body (12) having a male Luer lock connector (14) at one end connected in fluid communication with a female connector (28) at the other end. The female connector (28) is radially spaced from an outer wall (32) of the body (12) and has a Luer tapered bore (30) for receiving a male Luer tapered connector (62, 86) and a resilient locking member (40) connected to the body (12) at the other end thereof for frictionally engaging and locking the male Luer connector (62, 86) when inserted into the Luer tapered bore (30) to ensure against any subsequent fluid leakage between the connector.

Abstract: A syringe package includes a plastic cylindrical container sleeve closed at one end and open at the opposite end for receiving a sterile syringe. The sleeve has an enlarged end portion at the open end connected by a tapered portion to the main body portion of the sleeve. A rigid plastic end closure is positioned over the enlarged end portion of the sleeve and an end portion of the closure is heat-formed around the tapered portion of the sleeve so that the formed end of the cap has a smaller diameter than the enlarged portion of the sleeve. The heat-formed end portion of the closure may be provided with stress relief slots in the end portion.
