Valved bottle cap

Image Number 2 for United States Patent #5957316.

A cap for use with a dispensing system. The cap includes a main outer cap and an inner cap. The main outer cap has a central sleeve which receives and seals against a probe. The inner cap moves into and out of a sealing engagement with the central tube as the bottle is raised and lowered over the probe. The seal between the inner cap and the central tube is located on the outside surface of the central tube. The location of the connection between the inner cap and the probe is displaced away from the location of the connection between the inner cap and the sleeve of the main outer cap. This allows the cap to have effective differentials between the forces which are necessary to achieve proper sequencing of the formation of the various seals and connections which occur during use of the cap.
