Abstract

A nozzle for dispensing viscous fluid to avoid spraying and stringing, the nozzle including an inner tubular portion of a first cross-sectional area and an outer tubular portion of a second cross-sectional area, the inner tubular portion opening into the outer tubular portion and the outer tubular portion having an outlet, wherein fluid passes through the inner tubular portion into the outer tubular portion and subsequently out of the outer tubular portion via the outlet.

Claims (13)

1. A nozzle for dispensing fluid, the nozzle including an inner tubular portion of a first cross-sectional area and an outer tubular portion of a second cross-sectional area, the inner tubular portion opening into the outer tubular portion and the outer tubular portion having an outlet, wherein a fluid passageway is formed passing through the inner tubular portion into the outer tubular portion and subsequently out of the outer tubular portion via the outlet.
2. A nozzle as claimed in claim 1 wherein the inner tubular portion has an opening opening into the outer tubular portion, the outer tubular portion is directed generally vertically downwardly; and the opening of the inner tubular portion is directed generally vertically downwardly in alignment with the outlet of the outer tubular portion.
3. A nozzle as claimed in claim 2 wherein air inlet openings are provided opening into the outer tubular portion proximate a junction between the inner tubular portion and the outer tubular portion.
4. A nozzle as claimed in claim 3 wherein the air inlet openings are disposed about the inner tubular portion such that on flow of fluid out from the inner tubular portion into the outer tubular portion air is drawn inwardly into the outer tubular portion under a venturi effect.
5. A nozzle as claimed in claim 3 wherein the inner tubular portion comprises a cylindrical tube having a first bore therethrough of a first diameter and the outer tubular portion comprises an outer tube having a second bore therethrough of a second diameter larger than the diameter of the first bore.
6. A nozzle as claimed in claim 5 in which the diameter of the second bore is at least 5/3 the diameter of the first bore.
7. A nozzle as claimed in claim 5 wherein the diameter of the second bore is in the range of 0.5 to two times the diameter of the first bore.
8. A nozzle as claimed in claim 7 wherein the diameter of the first bore of the inner tube is in the range of two to ten millimeters.
9. A nozzle as claimed in claim 7 wherein the inner tubular portion and outer tubular portion are coaxial about an axis and the outlet of the outer tubular portion is disposed in a plane normal the axis.
10. A nozzle as claimed in claim 9 wherein the inner tubular portion and outer tubular portion are coaxial about an axis and the outlet of the outer tubular portion is disposed in a plane at an angle to the axis.
11. A fluid dispensing apparatus adapted to be activated to dispense through a nozzle a unit volume of fluid on each activation by a user, the nozzle having an inner tubular portion opening into an outer tubular portion having an outlet, the inner tubular portion and outer tubular portion defining a pathway for flow of fluid through the nozzle and out the outlet, the inner tubular portion having a cross-sectional area for flow therethrough smaller than a minimum cross-sectional area for flow through the outer tubular portion, the outer tubular portion defining a volume of the pathway for flow of in the range of 0.1 to 2 times the unit volume.
12. An apparatus as claimed in clam 11 wherein the volume of the outer tubular portion is in the range of 0.1 to 1 times the unit volume.
13. An apparatus as claimed in clam 11 wherein the volume of the outer tubular portion is in the range of 1/8 to 1/2 times the unit volume.
