Benefits of technology

[0105]prevents displacement of said tablet through said outlet when said valve member is in the open position yet said inlet is of a shape to allow said tablet to pass therethrough when said valve member is in said open position.

Problems solved by technology

When such a valve is used by a consumer the valve element can require considerable force to move it between opened and closed conditions.
Consumers often utilise their teeth to grasp the movable valve element to open it This can damage teeth, particularly of younger persons having teeth that may not be able to withstand the considerable force required to open the valve unit.

Embodiment Construction

[0166]Referring now to the drawings wherein like reference numerals identify similar structural elements or features of the subject invention, there is illustrated in FIG. 1 a flow switch or valve assembly 1 of prior art as found in our PCT Application WO2004 / 106782. More detail of the valve mechanism operation are described in WO2004 / 106782 which is hereby incorporated by way of reference. Various flow switch assemblies of the present invention define variations from the prior art. The variations are preferably for use in consumer beverage applications however alternative applications such as but not limited to plumbing or hydraulics, may also be mentioned or be apparent. Where reference herein is made to fluid or fluid flow or fluid communication it should also be appreciated that this could also be reference to solid or particulate materials.

[0167]The flow switch assembly 1 includes, inter alia, a valve housing 2 having an upper body portion 3 and a lower body portion 4 and a val...

Abstract

A flow switch assembly which includes a valve housing that includes an upper body portion and a lower body portion that are rotatably engaged relative each other. The upper and lower body portions define a chamber. The housing includes an inlet and outlet to the chamber. A valve member seated in the chamber of the valve housing for movement between an open position establishing at least one passage between the inlet and the outlet and a closed position wherein the at least one passage between the inlet and the outlet is non-established (preferably by said valve member sealing at least one of said inlet and outlet). There is also provided interactive cam elements associated with at least one of the upper body portion and the lower body portion, and associated with the valve member, are provided for moving the valve member between the open position and the closed position when the upper body portion of the housing is rotated relative to the lower body portion.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This is a continuation of application Ser. No. 11 / 413,741 filed Apr. 28, 2006, which in turn claims priority from U.S. Provisional Patent Application Ser. No. 60 / 675,668 filed Apr. 28, 2005, the disclosure of which is herein incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to a flow switch. Specifically although not solely the present invention relates to a flow switch for or of a consumer beverage container such as a beverage or water bottle, that incorporates the switch at the spout end of the container to control the dispensing of liquid from the container.[0003]Specifically although not solely the present invention may also relate to a flow switch that may have application other than for beverage container applications and that will hereinafter be described with reference to the drawings and detailed descriptions.BACKGROUND[0004]Drink containers that are currently in common use for th...
