A method of forming a unitary, sterile fluid dispensing assembly includes forming a fluid-filled container with a vinyl disposing port and forming a fluid transfer set with a vinyl spike connector. The spike connector is inserted into the vinyl disposing port thereby placing the set in fluid flow communication with the fluid in the container. The assembly is sterilized in an autoclave. The heat of sterilization melds at least a surface portion of the vinyl spike connector and softens an interior adjacent surface portion of the port on the container. After sterilization, the transfer set is permanently bonded to the container. The presence of the fluid in the transfer set during sterilization prevents fusing and closing of the lumens of the set due to the heat of sterilization.

Method of simultaneously assembling and sterilizing a unitary container

A universal connector for a fluid flow conduit comprises a tubular connector for attachment at one end to the fluid flow conduit and defining a luer taper tube portion at its other end. A sleeve is carried by and surrounding the tubular connector in relatively rotatable relation thereto. The sleeve defines internal threads for threaded locking connection with another connector. A tubular member having external threads at one end is locked by said external thread in removable threaded locking connection with the internal threads. The tubular member defines at its other end an aperture for sealingly receiving a spike connector.
