Method and system for the quick refill of an irritant dispenser
View Patent ↗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.
1. A dispenser of a pressurized substance comprising:
a dispensing nozzle having an internal channel leading to an external orifice for dispensing the pressurized substance, wherein said external orifice is located on a distal end of said dispensing nozzle, wherein a first quick connect fitting is formed from an exterior of the distal end of said dispensing nozzle, and wherein a proximal end of the dispensing nozzle forms a second quick connect fitting;
a valve assembly having a third quick connect fitting for detachably connecting to the second quick connect fitting and having a controllable valve for providing the pressurized substance through said quick connect connection 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 at least the first 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.
2. The dispenser of claim 1 , wherein the substance comprises a solid, a fluid, and/or a gas.
3. The dispenser of claim 1 , wherein the substance comprises an irritant and the target of the spray of irritant is a human and/or animal.
4. The dispenser of claim 1 , wherein the substance comprises a fire extinguishing material and the target of the spray of fire extinguishing material is a fire.
5. The dispenser of claim 1 , wherein a pressurization hose has a quick connect fitting capable of detachably connecting to at least the third 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 requiring an intermediate connection.
6. The dispenser of claim 1 , wherein the first quick connect fitting of the dispensing nozzle comprises a male quick connect plug.
7. The dispenser of claim 1 , wherein the first quick connect fitting of the dispensing nozzle comprises a female quick connect socket.
8. The dispenser of claim 1 , wherein the second quick connect fitting comprises a female quick connect socket, and the third quick connect fitting comprises a male quick connect plug.
9. The dispenser of claim 1 , wherein the second quick connect fitting comprises a male quick connect plug, and the third quick connect fitting comprises a female quick connect socket.
