Embodiment Construction

[0059] While the invention is capable of embodiment in many different forms, the specification and drawings disclose only one specific form as an illustration of the invention. However, the present invention will not be limited to the embodiments. The scope of the invention is set forth in the appended claims.

[0060] For ease of description, the valve of the present invention may be described with fittings in a typical (upright) position and terms such as upper, lower, horizontal etc. are used with reference to this position. However, it should be understood that valves employing the present invention may be manufactured, stored, shipped, used and sold in orientations other than those described above.

[0061] The drawings showing the valve of the present invention and associated fittings illustrate certain conventional mechanical elements that are well known and will be appreciated by those skilled in the art. A detailed description of these elements is not required to un...

Abstract

A slit valve (10) to selectively restrict the passage of a fluent substance between an interior environment (17) and an exterior environment (15) and a method for forming the valve (10), the method including the steps of providing at least one layer of film material and permanently deforming the film material to define a valve (10) for selectively restricting the passage of a fluent substance between an interior environment (17) and an exterior environment (15).

Description

technical field [0001] The present invention relates generally to valves and systems for selectively controlling the flow of fluent substances, and more particularly to valves for selectively restricting the flow of fluent substances between an internal environment and an external environment—for example, from a container or Valve for dispensing product from other sources. Background technique [0002] One type of flexible, resilient valve is a self-closing, slit-type valve that fits onto the port of a container of flowing substance or other source of flowing substance. Such valves have one or more slits defining a normally closed leak orifice that respond to an increased pressure differential across the valve (e.g., caused by increased pressure in the container when the container is squeezed, or by a pressure compared to the reduced external ambient pressure) to open allowing material to flow through the slit. Such valves are usually designed such that they automatically ...
