Abstract
Abstract A metal spray tip (34) for a fluid spray nozzle and a method of making such tip includes adhering a colored coating (24) so as to cover at least a portion of the exterior surface of the spray tip adjacent the spray orifice (30) in the tip. In one embodiment, the entiretip 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 (18') of the tip which does not contain the orifice may be coated.

Claim 1
Independent Claim
50 words
A spray tip for a fluid spray nozzle having a spray orifice therein for metering and spraying the fluid, wherein the improvement in said tip comprises: a colored coating adhering to and covering at least a portion of the exterior surface of said tip adjacent to the spray orifice therein.
Claim 2
Dependent Claim
50 words
A spray tip for a fluid spray nozzle having a spray orifice therein for metering and spraying the fluid, wherein the improvement in said tip comprises: a colored coating adhering to and covering at least a portion of the exterior surface of said tip adjacent to the spray orifice therein.
Claim 3
Dependent Claim
25 words
The spray tip of claim 1 wherein said tip includes a face having said spray orifice therein, said face having said colored coating adhering thereto.
Claim 4
Dependent Claim
52 words
The spray tip of claim 1 or claim 2, 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 the first mentioned portion.
Claim 5
Dependent Claim
44 words
A spray tip for a fluid spray nozzle having a spray orifice therein for metering and spraying the fluid and a substantially flat exterior face thereon, wherein the improvement in said tip comprises: a colored coating adhering to and covering said flat exterior face.
Claim 6
Dependent Claim
44 words
A spray tip for a fluid spray nozzle having a spray orifice therein for metering and spraying the fluid and a substantially flat exterior face thereon, wherein the improvement in said tip comprises: a colored coating adhering to and covering said flat exterior face.
Claim 7
Dependent Claim
16 words
The spray tip of claim 4, wherein said spray orifice is in said coated exterior face.
Claim 8
Dependent Claim
50 words
The spray tip of claim 4 or claim 5, 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 9
Dependent Claim
31 words
The spray tip of any one of the preceding claims wherein said colored coating covers substantially the entire exterior surface of said spray tip with the exception of said spray orifice.
Claim 10
Dependent Claim
55 words
The spray tip of any one of the preceding claims wherein said spray tip is metal and said orifice is free of said coating and is defined by the metal of said spray tip being exposed by forming said orifice in the spray tip subsequent to coating of the tip to remove said coating therefrom.
Claim 11
Dependent Claim
17 words
The spray tip of any one of the preceding claims wherein said coating is a printed coating.
Claim 12
Dependent Claim
24 words
The spray tip of any one of the preceding claims wherein said spray tip is metal and said coating is adhered to said metal.
Claim 13
Dependent Claim
35 words
A plurality of spray tips according to any one of the preceding claims, the coating of respective ones of said tips having differing colors denoting the flow rate of the respective ones of said tips.
Claim 14
Independent Claim
45 words
A method of forming a coated spray tip for a fluid spray nozzle comprising the steps of: coating a spray tip blank with a colored coating; and forming the spray orifice in the coated blank and through the coating after said coating has been applied.
Claim 15
Independent Claim
45 words
A method of forming a coated spray tip for a fluid spray nozzle comprising the steps of: coating a spray tip blank with a colored coating; and forming the spray orifice in the coated blank and through the coating after said coating has been applied.
Claim 16
Dependent Claim
14 words
The method of claim 12, wherein said coating is electrostatically applied to said blank.
Claim 17
Independent Claim
47 words
A method of forming a coated spray tip for a fluid spray nozzle comprising the steps of: applying a colored coating by printing the coating on a substantially flat face of said tip such that the coating is absent from the spray orifice of the spray tip.
Claim 18
Independent Claim
47 words
A method of forming a coated spray tip for a fluid spray nozzle comprising the steps of: applying a colored coating by printing the coating on a substantially flat face of said tip such that the coating is absent from the spray orifice of the spray tip.
Claim 19
Dependent Claim
44 words
The method of claim 14, wherein said orifice is formed in said face before said coating is printed upon said face and the coating image printed upon the face is free of said coating at said orifice, said coating being adjacent to said orifice.
Claim 20
Dependent Claim
49 words
The method of claim 14 or claim 15, 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 21
Independent Claim
25 words
The method of any one of claims 14 to 16 wherein said orifice is located on a portion of said tip other than said face.
