A port system for a blow molded intravenous solution container in which microbial contamination is prevented upon administration of the solution. The port system includes an integrally formed tube projecting outwardly from the container with a pierceable diaphragm positioned over the entry portion of the tube. Preferably, with respect to the tube entry portion, the diaphragm is concave, and may be made thinner in the center to facilitate proper placement of a piercing pin. In one embodiment, the port tube is inwardly flared adjacent the diaphragm so that as the piercing element is pushed through the diaphragm, the remnants of the pierced diaphragm can be pressed into the flared portion of the tube. |
