Abstract

A remote delivery nozzle assembly is adapted to be releasably connected to a pressurized container to permit delivery of the pressurized contents thereof to a location remote from the container. A cap assembly is connected through a flexible conduit to a wand for delivery of the pressurized contents of the container. Upon seating of the cap assembly on the container, the valve of the container is opened pressurizing the wand through the flexible conduit. The wand includes a flexible membrane which when depressed by finger pressure opens a valve between the pressurized inlet and an outlet passage to deliver the pressurized fluid.

Dependent claims

A remote delivery nozzle assembly adapted to be connected to a pressurized container for delivery of the pressurized contents of the container to a location remote from the container, the container being provided with an upstanding rim concentrically surrounding an upstanding hollow valve stem for releasing the pressurized contents of the container therefrom in response to shifting of the valve stem relative to the container from a normal disarmed mode position to a depressed armed mode position, said assembly comprising

an elongated wand member having a substantially parallel inlet and outlet passage,
remote valve means in a transverse bore between said inlet and outlet passage in said wand for selectively controlling the release of the pressurized contents from said container, said valve means including
reciprocably mounted plunger means in said transverse bore for opening and closing communication between said inlet and outlet passage in response to movement thereof,
flexible membrane means on said wand member for contact with said plunger means to impart movement to said plunger means in response to pressure applied thereto, and
a cap member to be seated on said flexible membrane means for imparting pressure to said flexible membrane means when pressed,
conduit means coupled to the inlet passage in said wand member for carrying the pressurized contents of said container from said container to said inlet passage,
means for releasably connecting the valve stem of the container with said conduit means, said connecting means including
cap means for enclosing said valve stem having an annular peripheral resilient flange provided with an edge adapted to frictionally engage the outer surface of the upstanding rim of the container and a plurality of interior, downwardly extending resilient prongs adapted to frictionally engage the inner surface of the upstanding rim of the container to removably mount said cap means on said container by clamping the rim between said interior prongs and peripheral flange, said cap means including a bore therethrough,
said conduit means extending through said bore in said cap means and secured to the latter, and
said cap means further including a shoulder within said bore adapted to engage said valve stem and force the latter to shift from a disarmed mode position therof to an armed mode position thereof when said cap means is installed on said container.

an elongated wand member having a substantially parallel inlet and outlet passage,
remote valve means in a transverse bore between said inlet and outlet passage in said wand for selectively controlling the release of the pressurized contents from said container, said valve means including
reciprocably mounted plunger means in said transverse bore for opening and closing communication between said inlet and outlet passage in response to movement thereof,
a plug fixed to said wand member having a portion extending into said transverse bore,
an annular shoulder forming a valve seat on said wand member surrounding said transverse bore between said parallel inlet and outlet passages,
an annular flange on said plunger means for forming a seal between said plunger means and annular shoulder, and
a spring extending between said plug and plunger means for urging said annular flange on said plunger means into sealing relation with said annular shoulder on said wand member, said plunger means having a cavity therein into which a longitudinal portion of said spring is inserted,
flexible membrane means on said wand member for contact with said plunger means to impart movement to said plunger means in response to pressure applied thereto, and
a cap member adapted to be seated on said flexible membrane means for imparting pressure to said flexible membrane means when pressed,
conduit means coupled to the inlet passage in said wand member for carrying the pressurized contents of said container from said container to said inlet passage,
means for releasably connecting the valve stem of the container with said conduit means, said connecting means including
