Patent attributes
A mounting system is provided for mounting a valve for accommodating the flow of fluent a substance from a supply of the fluent substance wherein the valve includes a peripheral attachment portion, an intermediate portion extending from the peripheral attachment portion, and a flexible, resilient head that extends from the intermediate portion and that has (a) a first side, (b) a second side, (c) at least one self-sealing slit through the head, (d) a laterally marginal portion adjacent the intermediate portion, and (e) confronting, openable portions along the slit to define an initially closed orifice. The mounting system includes a retention structure for engaging holding the valve and includes an abutment structure. The abutment structure is adapted to be disposed adjacent the valve intermediate portion so that the abutment structure can be engaged by the valve head first side at the laterally marginal portion of the valve head to limit movement of the laterally margin portion of the valve head in one direction.
