Apparatus and method for spraying liquid

Abstract

A liquid to be sprayed and pressurized aerosol are placed in a canister. One end of a hose line is installed in the canister and the other end of the hose is connected to a spray valve which is contained within an actuator assembly. The spray valve is manually actuated by an actuator formed in the actuator assembly. A spray gun has an actuator which abuts against the actuator formed in the actuator assembly and when manually triggered actuates the spray valve to spray the liquid.

1 . A system for dispensing liquid in the form of a spray comprising a canister for containing liquid; 
 a liquid to be sprayed contained within said canister;    a pressurized gas spray for driving said liquid contained within said canister;    a valve for releasing said liquid in the form of a spray;    a means for actuating said valve to release said liquid;    a hose line, one end of said hose line being connected to within said canister to receive liquid therefrom, and    means for removably connecting the other end of said hose line to said valve in an air tight manner.    
   
   
       2 . The system of  claim 1  wherein said means for actuating said valve comprises an actuator assembly surrounding said valve and including a manually actuable member for actuating the valve.  
   
   
       3 . The system of  claim 1  wherein said means for actuating said valve further includes a gun for actuating said manually actuable member.  
   
   
       4 . The system of  claim 1  wherein said means for removably connecting said valve to said hose comprises an actuator assembly connected to said valve, said actuator assembly including a top portion having a channel formed there through, a tubular extension portion fluidly coupled to said top portion and having a reduced diameter, said extension portion being fitted within the hose, a threaded tube, a nut having threads which engage the threads of said tube, a clamp fitting having an aperture formed in the central portion thereof, said clamp fitting having inwardly tapered portions at both ends thereof, one of said tapered portions abutting against one end of said threaded tube, said threaded tube being rotatably tightened in said nut against said one of said tapered portions of said clamp fitting, the other of the tapered portions of said clamp fitting being driven against the portion of the hose in which said extension portion is fitted.  
   
   
       5 . The system of  claim 1  and further including a housing for housing both the actuating means and the connecting means  
   
   
       6 . A method for spraying liquid comprising the steps of: 
 filling a canister with liquid to be sprayed and a pressurized gas for driving said liquid;    connecting one end of a hose line to the interior of said canister;    removably connecting the end of said hose line opposite to said one end of said hose line to a valve in an air tight manner to convey said liquid to said valve,    placing an actuator for actuating said valve in proximity to said valve; and manually actuating said valve to spray said liquid therefrom.    
   
   
       7 . The method of  claim 6  and further including mounting said actuator and valve within the housing.
