Claim 4

having an offcenter hole securing the valve stem and a flange provided with a container rim-engaging lip

Claim 5

The assembly defined in claim 1 wherein the sleeve coupling is asymmetrical and is provided with an axial bore for telescoping interfitting engagement with the hollow valve stem at the lower end of the coupling and for telescoping interfitting engagement with the flexible tubing at the upper end of the coupling, and wherein the coupling is provided with an eccentric sleeve projection surrounding its axial bore and interferingly engageable with a corresponding eccentric aperture formed in the container cap means, whereby relative rotation movement of the cap means with respect to the pressurized container increases the interfering juxtaposition of the eccentric aperture and the eccentric sleeve, causing the cap to apply lateral force against the eccentric sleeve, producing angular tilting movement of the coupling and of the valve stem engaged therewith to move the valve stem from a first closed position to an angularly-tilted open position, arming the assembly by connecting the pressurized fluid within the pressurized container via the flexible tubing to the internal bore of the remote release nozzle wand.

Claim 6

Claim 7

and movable between a first ''''armed mode'''' position and a second ''''disarmed mode'''' position, whereby movement of the container cap means to its ''''armed mode'''' position tilts said sleeve coupling and said upstanding tiltable valve stem from its normally upright disarmed mode position to its tilted ''''armed mode'''' position, and movement of the cap means to its ''''disarmed mode'''' position allows the tiltable valve stem to return to its normally upright ''''disarmed mode'''' position.

Claim 8

and movable between a first ''''armed mode'''' position and a second ''''disarmed mode'''' position, whereby movement of the container cap means to its ''''armed mode'''' position tilts said sleeve coupling and said upstanding tiltable valve stem from its normally upright disarmed mode position to its tilted ''''armed mode'''' position, and movement of the cap means to its ''''disarmed mode'''' position allows the tiltable valve stem to return to its normally upright ''''disarmed mode'''' position.

Claim 9

The assembly defined in claim 1 wherein the elongated conduit is a length of flexible tubing.

Claim 10

The assembly defined in claim 1 wherein the remote release valve and the pressurized container valve stem are both actuated to opened positions by lateral angular tilting movement from normal axial closed positions, and wherein the terminating release valve of the remote pressure release nozzle wand forms A short axial extension of the wand normally resiliently biassed toward a substantially coaxial sealed position and actuated by lateral tilting force into an angularly tilted delivery position relative to the wand.

Claim 11

A remote-release, manually-armed and actuated pressurized-container assembly comprising: A. A pressurized container; B. An associated remote pressure release nozzle wand terminating in a manually actuatable pressure release valve closing an internal bore therein; C. An elongated flexible conduit having a remote end sealingly connected to the internal bore of the remote pressure release nozzle wand; D. A laterally tiltable upstanding closure valve stem mounted on the container top and secured to the opposite end of the conduit, connecting the container interior to the conduit in a tilted ''''armed'''' mode of the valve stem and disconnecting the container interior from the conduit in a nontilted ''''disarmed'''' mode thereof, and E. A manually-movable eccentric arming unit incorporating a sleeve coupling sealingly joining the valve stem to the conduit, and an eccentric coupling-tilter positioned to impart tilting translation movement to the sleeve coupling, said coupling-tilter having an offcenter hole encircling the valve stem and being interferingly engageable between the container top and the tiltable valve stem sleeve to maintain the valve stem in its tilted ''''armed'''' mode by applying lateral tilting force to the tiltable valve stem and being disengageable to release the valve stem to its nontilted ''''disarmed'''' mode, and F. With the wand pressure release valve forming an axial extension of the remote pressure release nozzle wand which is normally resiliently biased toward a first substantially coaxial, closed position by resilient spring means within the internal wand bore, and which is actuated by manual force overriding the resilient biasing force of said spring means directed to displace the pressure release valve relative to said wand to a second, open position.

Claim 12

A remote-release, manually-armed and actuated pressurized-container assembly comprising: A. A pressurized container; B. An associated remote pressure release nozzle wand terminating in a manually actuatable pressure release valve closing an internal bore therein; C. An elongated flexible conduit having a remote end sealingly connected to the internal bore of the remote pressure release nozzle wand; D. A laterally tiltable upstanding closure valve stem mounted on the container top and secured to the opposite end of the conduit, connecting the container interior to the conduit in a tilted ''''armed'''' mode of the valve stem and disconnecting the container interior from the conduit in a nontilted ''''disarmed'''' mode thereof, and E. A manually-movable eccentric arming unit incorporating a sleeve coupling sealingly joining the valve stem to the conduit, and an eccentric coupling-tilter positioned to impart tilting translation movement to the sleeve coupling, said coupling-tilter having an offcenter hole encircling the valve stem and being interferingly engageable between the container top and the tiltable valve stem sleeve to maintain the valve stem in its tilted ''''armed'''' mode by applying lateral tilting force to the tiltable valve stem and being disengageable to release the valve stem to its nontilted ''''disarmed'''' mode, and F. With the wand pressure release valve forming an axial extension of the remote pressure release nozzle wand which is normally resiliently biased toward a first substantially coaxial, closed position by resilient spring means within the internal wand bore, and which is actuated by manual force overriding the resilient biasing force of said spring means directed to displace the pressure release valve relative to said wand to a second, open position.

And said resilient spring means being positioned in the wand bore and normally biasing the valve conduit''s cupped flange toward the elastomer washer blocking passage of gas through the metering orifice in the closed position of the release valve, whereby manual force displacing the release valve deforms the spring means to open the metering orifice and released pressurized gas from the wand bore for delivery through the tubular valve conduit.
