A port closure system () including a retention structure (), and a valve (). The retention structure () includes a port () for establishing communication between an exterior environment () and interior volume () that can receive a fluent substance. The valve () includes a flexible, resilient, self-closing, slit-type valve head () with an orifice that is normally closed in an unconstrained condition. The port () has a laterally inwardly facing engaging surface () and the valve has a laterally outwardly facing peripheral surface () that is compressed laterally inwardly by engagement with the surface () to increase the resistance of the normally closed orifice to opening when the head () is subjected to a pressure differential. The system () further includes an annular flange () located to extend over at least a portion of an exterior side () of the valve head () to limit movement of the valve head () towards the exterior environment ().

Port closure system for use with a probe/feed/drain tool

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.

Valve mounting assembly with slit misalignment prevention feature

A port closure system () including a port structure (), and a valve (). The port structure () includes a port () for establishing communication between an exterior environment () and interior volume () that can receive a fluent substance. The valve () includes a flexible, resilient, self-closing, slit-type valve head () with an orifice that is normally closed in an unconstrained condition. The port () has a laterally inwardly facing engaging surface () and the valve has a laterally outwardly facing peripheral surface () that is compressed laterally inwardly by engagement with the surface () to increase the resistance of the normally closed orifice to opening when the head () is subjected to a pressure differential.

Port closure system with hydraulic hammer resistance

A fluid dispensing valve is provided with a peripheral mounting portion and a connecting sleeve connecting the peripheral mounting portion with a head which defines a dispensing orifice. The valve head includes a central inner surface portion that bulges axially inwardly to project from a radially outer surface portion.

Dispensing valve with hydraulic hammer resistance

A flow control element is provided with a resilient sealing flange biased to seal in-venting passages in a housing around the element. The element also includes a self-sealing, pressure-openable, dispensing valve. The element and housing can be combined to form a dispensing structure that can function to discharge a fluent material product out of the dispensing structure through the dispensing valve while simultaneously venting exterior ambient air (or other exterior ambient environment fluent material) into the dispensing structure.
