The disclosed embodiments provide a valve structure that is hermetically sealed to a lower flange formed on an IV bag to form a one-way outlet accessible with a luer tip syringe that does not have a needle. The valve structure can include a piston in combination with a disc or disc valve. The piston can have a slit septum or opening allowing access to an interior surface of the piston. The disc valve is typically in a closed position that prevents injections or other incursions into the bag, thus preserving the integrity and sterility of the bag contents. |
