Abstract
A system and method for quickly refilling a pressurized irritant dispenser is disclosed. In the system and method, either the dispensing nozzle or the connection between the dispensing nozzle and the valve assembly is replaced with a quick connect fitting. The quick connect fitting allows for both the quick refill of irritant and the quick attachment (and detachment) of various accessories to the pressurized irritant dispenser.
Claims24
An apparatus for dispensing pressurized irritant comprising:
- a valve assembly to which a dispensing nozzle may be detachably connected by a quick connect fitting on said valve assembly which engages a quick connect fitting on a proximal end of the dispensing nozzle, said valve assembly having a controllable valve for providing irritant from an irritant container to the dispensing nozzle;
- wherein a pressurization hose has a quick connect fitting capable of detachably connecting to the quick connect fitting of the valve assembly, whereby one can pressurize the contents of the irritant container by attaching the pressurization hose directly to the valve assembly without need for an intermediate coupling.
A hand-held dispenser for targeting a spray of pressurized substance comprising:
- a dispensing nozzle having an internal channel leading to an external orifice out of which is sprayed the pressurized substance, wherein said external orifice is located on a distal end of said dispensing nozzle, wherein a quick connect fitting is formed from an exterior of the distal end of said dispensing nozzle;
- a valve assembly to which a proximal end of said dispensing nozzle is connected having a controllable valve for providing the pressurized substance to said dispensing nozzle;
- and
- a container connected to said valve assembly for providing a supply of the substance to be dispensed through said valve assembly to said dispensing nozzle;
- wherein a pressurization hose has a quick connect fitting capable of detachably connecting to the quick connect fitting of the dispensing nozzle, whereby one can pressurize the contents of the container by attaching the pressurization hose to the dispensing nozzle without removing the dispensing nozzle from the valve assembly;
- and
- wherein a person can carry the hand-held dispenser comprising said dispensing nozzle, said valve assembly, and said container and target the spray of the hand-held dispenser at the same time.

A hand-held dispenser for targeting a spray of pressurized substance comprising:
- a dispensing nozzle having an internal channel leading to an external orifice out of which is sprayed the pressurized substance, wherein said external orifice is located on a distal end of said dispensing nozzle, wherein a proximal end of said dispensing nozzle forms a first quick connect fitting;
- a valve assembly having a second quick connect fitting for engaging the first quick connect fitting of the dispensing nozzle, said valve assembly having a controllable valve for providing the pressurized substance to said dispensing nozzle;
- and
- a container connected to said valve assembly for providing a supply of the substance to be dispensed through said valve assembly to said dispensing nozzle;
- wherein a pressurization hose has a quick connect fitting capable of detachably connecting to the second quick connect fitting of the valve assembly, whereby one can pressurize the contents of the container by attaching the pressurization hose directly to the valve assembly without needing an intermediate coupling;
- and
- wherein a person can carry the hand-held dispenser comprising said dispensing nozzle, said valve assembly, and said container and target the spray of the hand-held dispenser at the same time.

A method for pressurizing a hand-held dispenser capable of targeting a spray of pressurized substance, said hand-held dispenser comprising a dispensing nozzle connected to a valve assembly connected to a container of the pressurized substance, comprising the steps of:
- connecting a quick connect fitting of a pressurization hose to either a quick connect fitting formed from a distal end of the dispensing nozzle of the hand-held dispenser or a quick connect fitting formed in the valve assembly of the hand-held dispenser;
- pressurizing the container using the pressurization hose connected to said either the dispensing nozzle or the valve assembly of the hand-held dispenser;
- and
- disconnecting the quick connect fitting of the pressurization hose from said either the quick connect fitting formed from the distal end of the dispensing nozzle of the pressurized irritant dispenser or the quick connect fitting formed in the valve assembly of the pressurized irritant dispenser;
- whereby one can pressurize the contents of the container by attaching the pressurization hose directly to said either the dispensing nozzle or the valve assembly without needing an intermediate coupling;
- wherein, if the quick connect fitting of the pressurization hose is connected to the quick connect fitting formed from the distal end of the dispensing nozzle of the pressurized irritant dispenser, one can pressurize the container without removing the dispensing nozzle from the valve assembly;
- and
- wherein a person can carry the hand-held dispenser and target the spray of the hand-held dispenser at the same time.
