Claim 16

A dispensing valve for a fluid-holding container comprising: a valve body including a first portion having a first fluid passageway and a second portion having a second fluid passageway terminating in a first open end and a second generally closed second end, said first passageway communicating with said second passageway at a port in the side wall of said second passageway; a handle operatively associated with said body second portion and having a finger portion extending into said second passageway, said handle being selectively moveable between valve open and closed conditions; a resiliently deformable seal member closely disposed in said second passageway in a normally closing and overlying relationship with said port, said seal member being shearingly deformable away from said port and including a connecting area thereon operatively associated with said handle finger for effecting shearing movement of said seal member to an opening relationship with said port in response to movement of said handle; and, mounting means adapted for mounting said valve body to an associated container.

Claim 17

The fluid valve of claim 14 wherein said seal member has a tube-like conformation, and is closely received and retained in said second passageway by an interference fit.

Claim 18

The fluid valve of claim 14 wherein said mounting means includes an exteriorly threaded section on an outer end of said body first portion and a nut adapted for threaded receipt thereon.

Claim 19

The fluid valve of claim 16 wherein said mounting means further includes a radial flange axially spaced from said body first portion outer end adjacent said threaded section, and said first portion including plural flat surfaces on the other side of said flange from said threaded section for defining a wrench grip.

Claim 20

A self-closing valve for dispensing fluid products, comprising: a body member including a first portion having a first passageway and a second portion having a second passageway with said first and second passageway being disposed in fluid communication to each other at a port disposed in the side wall of said second passageway; a handle having a finger portion extending into said second passageway; means for operatively mounting said handle to said body for accommodating selective handle movement between valve open and closed conditions; a resilient seal member closely received in said second passageway and having a normal position disposed in covering relation to said port, said seal member being resiliently and shearingly deformable to a second position in uncovering relation to said port adapted to allow fluid flow between said first passageway to said second passageway; and, means for operatively connecting said handle finger portion to said seal member for allowing said seal member to be shearingly moved between said normal and second positions in response to movement of said handle between said valve closed and open conditions, respectively.

Claim 21
