Filed:

May 25, 2005

Appl. No.:

11/137188

Inventors:

William Conard - Pennsburg PA, US
Robert Buck - Watsontown PA, US
Neil Strausbaugh - Williamsport PA, US
Robert King - Malvern PA, US
Diane Crammer - Phoenixville PA, US

International Classification:

B29C 45/14
B28B 7/22

US Classification:

604403000, 264255000, 264328800

Abstract:

An injection port for an intravenous bag including a generally hollow tube that is mountable to the intravenous bag. The hollow tube has a first end. A polymeric plug is mounted in the first end. The polymeric plug is integrally molded into the tube proximate the first end. A method for constructing the injection port including injecting a first molding material into a mold cavity, allowing the first molding material to at least partially cure and harden, moving a movable mold part to expose a first cavity defined by inner surfaces of the at least partially cured and hardened molding material, injecting a second mold material into the first cavity, allowing the second molding material to at least partially cure and harden such that the second molding material bonds with the inner surfaces and removing the injection port from the mold.
