Abstract

A multi-hole nozzle component having a periphery, an inlet side and an opposing outlet side. The nozzle component having a plurality of first passageways having a plurality of first openings each first opening having a first opening area, a plurality of second passageways having a plurality of second openings each second opening having a second opening area, and a plurality of third passageways having a plurality third openings each third opening having a third opening area. The plurality of second openings are arranged about the plurality of first openings. The plurality of third openings are arranged about the plurality of first openings. The second opening area is greater than the first opening area and the second opening area is about equal to the third opening area.

First claim

What is claimed is:

1. A multi-hole nozzle component comprising:
a periphery, an inlet side having an inlet surface, an outlet side opposing said inlet side having an outlet surface, a longitudinal axis extending from said inlet side to said outlet side;
a plurality of first passageways extending through said nozzle component from said inlet side to said outlet side, wherein said plurality of first passageways form a plurality of first openings at said outlet surface, wherein said plurality of first openings are arranged about said longitudinal axis of said nozzle component, wherein each of said first openings has a first opening area and a first opening diameter;
a plurality of second passageways extending through said nozzle component from said inlet side to said outlet side, wherein said plurality of second passageways form a plurality of second openings at said outlet surface, wherein said plurality of second openings are arranged about said plurality of first openings, wherein each of said second openings has a second opening area and a second opening diameter, wherein said second opening area is greater than said first opening area; and
a plurality of third passageways extending through said nozzle component from said inlet side to said outlet side, wherein said plurality of third passageways form a plurality of third openings at said outlet surface, wherein said plurality of third openings are arranged about said plurality of second openings, wherein each of said third openings has a third opening area and a third opening diameter, and wherein said third opening area is about equal to said second opening area;
wherein said plurality of first openings, said plurality of second openings, and said plurality of third openings are substantially circular;
wherein each of said passageways has a respective inner diameter wherein the inner diameter of each passageway is the same throughout the length of the passageway and wherein the inner diameter of each passageway is the same as the respective first opening diameter, second opening diameter, and third opening diameter of each passageway.

2. The multi-hole nozzle component of claim 1 , wherein said nozzle component has a centroid, and wherein said longitudinal axis passes through said centroid.

3. The multi-hole nozzle component of claim 2 , wherein said plurality of first openings, said plurality of second openings, and said plurality of third openings are concentric about said longitudinal axis.

4. The multi-hole nozzle component of claim 1 , wherein each of said first openings, each of said second openings, and each of said third openings are sized and configured so that when liquid is dispensed through said nozzle component, the liquid exits the outlet side in the form of separate streams from each opening.

5. The multi-hole nozzle component of claim 1 , wherein said plurality of first openings has fewer openings than said plurality of second openings.

6. The multi-hole nozzle component of claim 5 , wherein said plurality of second openings has fewer openings than said plurality of third openings.

7. The multi-hole nozzle component of claim 1 , wherein said first opening diameter to said second opening diameter has a ratio of about 2:3.

8. The multi-hole nozzle component of claim 1 , wherein said plurality of first passageways, said plurality of second passageways, and said plurality of third passageways extending through said nozzle component are substantially parallel to each other.

9. The multi-hole nozzle component of claim 1 , wherein said plurality of first passageways, said plurality of second passageways, and said plurality of third passageways have substantially circular cross-sections.

10. The multi-hole nozzle component of claim 1 , wherein said nozzle component comprises a plurality of grooves in said outlet surface that are disposed to run among said first openings, said second openings, and said third openings, and wherein each of said grooves are sized and configured to reduce dripping of liquid after said nozzle component is closed by separating said first openings, said second openings, and said third openings at said outlet surface such that any individual meniscus formed at said first openings, said second openings, or said third openings at the outlet surface of said nozzle component cannot combine to produce a large drop.

11. The multi-hole nozzle component of claim 10 , wherein said grooves at least partially surround said plurality of first openings, said plurality of second openings, and said plurality of third openings to separate said plurality of first openings, said plurality of second openings, and said plurality of third openings from each other, and wherein each groove is in a substantially circular arrangement.

12. The multi-hole nozzle component of claim 10 , wherein said grooves extend radially outward from said longitudinal axis towards said periphery of said nozzle component.

13. The multi-hole nozzle component of claim 1 , wherein each of said first passageways, said second passageways, and said third passageways has a distal end and an opposing proximal end attached to said outlet surface, wherein each of said distal ends projects beyond said outlet surface by a predetermined magnitude of projection.

14. The multi-hole nozzle component of claim 13 , wherein each of said distal ends of each of said plurality of first passageways, said second passageways, and said third passageways projects beyond said outlet surface by the same predetermined magnitude of projection.

15. The multi-hole nozzle component of claim 13 , wherein each of said distal ends of each of said plurality of first passageways, said second passageways, and said third passageways projects beyond said outlet surface by varying predetermined magnitudes of projection.

16. The multi-hole nozzle component of claim 1 , wherein said nozzle component further comprises a centering feature that extends outwardly from said outlet side.

17. A method of dispensing liquid comprising the steps of providing a low viscosity liquid, providing a container, and filling the container with the multi-hole nozzle component of claim 1 .
