Embodiment Construction

[0035] Although the invention allows for many different forms of embodiment, the specification and drawings disclose only one specific form as an example of the invention. However, the invention is not intended to be limited to the described embodiments. The scope of the invention is indicated in the appended claims.

[0036] As will be discussed in detail below, the port closure system of the present invention can be used to install a valve in a fluid handling system, including an associated container or other dispensing structure, to allow the delivery of fluid substances, including but not limited to water , beer, or other fluids fit for consumption.

[0037] Notably, the port closure system of the present invention is particularly suitable for use with flexible, resilient valves of the type comprising a peripheral attachment portion of the valve and a central valve head (typically capable of opening in either of two opposite directions) .

[0038] For ease of descriptio...

Abstract

A port closure system (20) includes a port structure (22) and a valve (24). The port arrangement (22) includes a port (28) for establishing communication between an external environment (30) and an internal volume (32) capable of containing a fluid substance. The valve (24) includes a flexible, resilient, self-closing, slot-type valve head (36) having an orifice that is normally closed in an unconstrained state. the port (28) has a laterally inwardly facing engagement surface (34) and the valve has a laterally outwardly facing peripheral surface (54) which is compressed laterally inwardly by engagement with the surface (34), This increases the resistance of the normally closed orifice to opening when the head (36) is subjected to a differential pressure.

Description

technical field [0001] The present invention generally relates to systems for accommodating the flow of fluid substances. More specifically, the present invention relates to a port closure system having a flexible, resilient valve and allowing flow of a fluid substance through the valve. Background technique [0002] The inventors of the present invention have discovered that it would be advantageous to provide an improved system for holding or otherwise mounting a flexible, resilient valve defining an initially closed orifice that can be opened to accommodate passage of the Fluid flow through valves described above, where the design of the system may provide advantages that have not heretofore been conceived in the industry or conceived from the prior art. In particular, the system of the present invention facilitates correct closing of the valve after parts of the valve have been forced out of its initial closed configuration, and is resistant to hydraulic hammer caused b...
