Abstract
An airless spray nozzle tip (10) for use in coating workpieces such as containers includes a first groove (40) located on one side (24) of the tip, and second (30), third (32) and fourth (34) grooves located on the other side of the tip, thereby forming three orifices in the nozzle tip (10). The nozzle tip (10) produces a generally circular spray pattern with a diameter of at least about one half inch, at a distance in the range of from about one inch to about three inches from the nozzle tip, and at a flow rate at or below about 0.045 galloons per minute. A process of coating a workpiece, such as a container, includes spraying liquid from a nozzle tip to procuce this generally circular pattern, the nozzle tip preferably having three orifices.
Claims16
An airless spray nozzle tip having first and second major sides;
- a first groove on said first major side of said tip;
- and
- a second groove and a third groove and a fourth groove on said second major side of said tip, said second and third and fourth grooves extending parallel to each other and perpendicular to said first groove;
- each one of said second groove and said third groove and said fourth groove penetrating said first groove, thereby forming a first orifice and a second orifice and a third orifice in said nozzle tip.
A process of coating a workpiece with liquid sprayed from a nozzle, said process including the steps of:
- directing the liquid at the workpiece through a nozzle tip in the nozzle;
- and
- producing a generally circular pattern with a diameter above about one half inch, at a distance in the range of from about one inch to about three inches from the nozzle tip, and at a flow rate below about 0.045 gallons per minute.
A process of coating a portion of a container with liquid sprayed from a nozzle, said process including the steps of:
- directing the liquid at the container through a nozzle tip in the nozzle;
- and
- producing a generally circular pattern with a diameter above about one half inch, at a distance in the range of from about one inch to about three inches from the nozzle tip, and at a flow rate below about 0.045 gallons per minute.
An airless spray nozzle tip for spraying liquid at a workpiece;
- said nozzle tip having first and second sides;
- said nozzle tip having a plurality of orifices extending between said first and second sides for spraying the liquid at the workpiece;
- said nozzle producing a generally circular spray pattern with a diameter of at least about one half inch, at a distance in the range of from about one inch to about three inches from the nozzle tip, and at a flow rate at or below about 0.045 gallons per minute.
