Abstract
Abstract A metal spray tip for a fluid spray nozzle and a method of making such tip includes adhering a colored coating so as to cover at least a portion of the exterior surface of the spray tip adjacent the spray orifice in the tip. In one embodiment, the entire tip blank is first coated and then the orifice is formed in the coated blank to free the orifice of the coating and expose the metal of the tip at the orifice. In another embodiment, the orifice is first formed in a face of the tip and the tip face containing the orifice is then printed with the coating. In the latter embodiment, preferably only a portion of the exterior surface of the tip is coated to leave the metal exposed on some portions of the exterior surface. In still another embodiment of tip, a substantially flat exterior face of the tip which does not contain the orifice may be coated.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
83 words
A spray tip for a fluid spray nozzle, said tip being formed of a base material and having a spray orifice in a substantially flat exterior face thereon for metering and spraying the fluid, wherein the improvement in said tip comprises: a colored coating printed on, adhering to and covering the base material of said flat exterior face, said base material of said tip being free of said coating at said spray orifice so that said orifice is not impaired by said coating.
Claim 2
Dependent Claim
83 words
A spray tip for a fluid spray nozzle, said tip being formed of a base material and having a spray orifice in a substantially flat exterior face thereon for metering and spraying the fluid, wherein the improvement in said tip comprises: a colored coating printed on, adhering to and covering the base material of said flat exterior face, said base material of said tip being free of said coating at said spray orifice so that said orifice is not impaired by said coating.
Claim 3
Dependent Claim
20 words
The spray tip of claim 1, wherein the color of said coating denotes the flow rate of said spray tip.
Claim 4
Dependent Claim
35 words
The spray tip of claim 1, comprising a plurality of said spray tips, the coating of respective ones of said tips having differing colors denoting the flow rate of the respective ones of said tips.
Claim 5
Dependent Claim
47 words
The spray tip of claim 1, wherein said tip is metal and said colored coating is also adhered to other, but less than all of the exterior surfaces of said tip to expose the metal of said tip on portions of said tip other than said face.
Claim 6
Dependent Claim
20 words
The spray tip of claim 1, wherein said spray tip is metal and said coating is adhered to said metal.
Claim 7
Independent Claim
82 words
A method of forming a coated spray tip for a fluid spray nozzle comprising the steps of: forming a spray orifice in a substantially flat face of said spray tip, and subsequently applying a colored coating by printing a coating image which is free of said coating at said orifice on said substantially flat face of said tip such that the coating is absent from the spray orifice of the spray tip so that said orifice is not impaired by said coating.
Claim 8
Independent Claim
82 words
A method of forming a coated spray tip for a fluid spray nozzle comprising the steps of: forming a spray orifice in a substantially flat face of said spray tip, and subsequently applying a colored coating by printing a coating image which is free of said coating at said orifice on said substantially flat face of said tip such that the coating is absent from the spray orifice of the spray tip so that said orifice is not impaired by said coating.
Claim 9
Dependent Claim
46 words
The method of claim 6, wherein said tip is metal and said coating is applied to other, but less than all of the exterior metal surfaces of said tip to expose the metal of said tip on portions of said tip other than the coated portions.
Claim 10
Dependent Claim
19 words
The method of claim 6, wherein said spray tip is metal and said coating is adhered to said metal.
