Double shut-off fluid dispenser element

An improved valved element for interconnection between a tubular fitment sealed around an opening in a fluid container and extending from the exterior surface of the container, and a valved fluid dispensing member having a normally closed valve having an axially movable spring biased valve opening member, said improved valved element comprising:

• a resilient housing having first and second tubular ends, said first tubular end being sealable within the tubular fitment said second end being closed with an axial valve seat opened toward said valved fluid dispensing member;
• an annular resilient ring formed around the second end of said resilient housing for sealing said housing to said dispensing member, said ring formed in said resilient housing and overlying an annular groove formed in the second end of said housing;
• a tubular extension skirt on said first tubular end, said skirt extendable through the fluid container opening into the fluid container, said skirt having openings for the passage of fluid therethrough;
• and
• elongated valve means axially movable within said resilient tubular housing and having a valve member at a second end and positioned to be axially moved into and from said valve seat by the spring biased valve opening member in said valved fluid dispensing member, said elongated valve means having a first end resiliently coupled to the interior surface of the first tubular end of said resilient housing, said elongated valve means remaining axially centered within said tubular housing by at least three longitudinally elongated fins radially extending from said valve means.
