What is claimed is:

1. A self-venting nozzle adapted to vent a gas entrained in a fluid to an atmosphere, the nozzle comprising:

a nozzle inlet end;

a nozzle outlet end;

a nozzle wall extending between the nozzle inlet end and nozzle outlet end and having an interior surface defining a fluid channel surrounding a nozzle flow axis; and

one or more vent passageways providing fluid communication between the fluid channel and the atmosphere.

2. The self-venting nozzle of claim 1, wherein the nozzle comprises a mating portion adapted to connect to a dispenser.

3. The self-venting nozzle of claim 2, wherein the mating portion is disposed on the interior surface.

4. The self-venting nozzle of any of the preceding claims, wherein the one or more vent passageways extend along the interior surface.

5. The self-venting nozzle of claim 2, further comprising an exterior surface wherein the mating portion is disposed on the exterior surface.

6. The self-venting nozzle of claim 5, wherein the one or more vent passageways extend along the exterior surface.

7. The self-venting nozzle of any one of claims 2-6, wherein the one or more vent passageways extend along at least a portion of the mating portion.

8. The self-venting nozzle of any one of claims 1-4 or 7, wherein the one or more vent passageways comprise grooves in the interior surface.

9. The self-venting nozzle of any one of claims 5-7, wherein the one or more vent passageways comprise grooves in the exterior surface.

10. The self-venting nozzle of any one of the preceding claims, wherein the one or more vent passageways run in a direction substantially parallel to the flow axis.

1 1. The self-venting nozzle of any one of claims 2- 10, wherein the nozzle further comprises a first non-mating portion disposed between the outlet end and the mating portion.

12. The self-venting nozzle of claim 1 1, wherein the one or more vent passageways extend along at least a portion of the first non-mating portion.

13. The self-venting nozzle of any one of claims 2-12, wherein the nozzle further comprises a second non-mating portion disposed between the mating portion and the inlet end.

14. The self-venting nozzle of claim 13, wherein the one or more vent passageways extend along at least a portion of the second non-mating portion.

15. The self-venting nozzle of any one of claims 1-4, wherein the one or more vent passageways extend through the wall from the interior surface to the exterior surface.

16. The self-venting nozzle of any one of the preceding claims, further comprising a dynamic mixing assembly disposed upstream of the inlet end.

17. The self-venting nozzle of any one of the preceding claims, wherein the nozzle comprises a first nozzle portion and a second nozzle portion and wherein the nozzle outlet end is located on the first nozzle portion and the nozzle inlet end is located on the second nozzle portion.

18. The self-venting nozzle of claim 17, wherein the one or more vent passageways are located at an interface between the first nozzle portion and the second nozzle portion.

19. The self-venting nozzle of any one of the preceding claims, wherein the one or more passageways are adapted to allow passage of fluid having a viscosity of no greater than 500,000 mPa.s.

20. The self-venting nozzle of any one of the preceding claims, wherein the one or more vent passageways have an effective cross-sectional area of from 6.4x10"5 cm2 to 0.65 cm .

21. A nozzle system comprising the self-venting nozzle of any one of the preceding claims and a dispenser.

22. The nozzle system of claim 21, wherein the dispenser comprises an outlet port adapted to connect to the mating portion of the self-venting nozzle.

23. The nozzle system of anyone of claims 21-22, wherein the dispenser is arranged upstream of the self-venting nozzle.

24. The nozzle system of anyone of claims 21-23, wherein the dispenser comprises a mixing tip.

25. The nozzle system of claim 24, wherein the mixing tip is a dynamic mixing tip.

26. The nozzle system of claim 24, wherein the mixing tip is a static mixing tip.

A method of dispensing a fluid having a gas entrained therein, comprising:

providing a self-venting nozzle according to any one of claims 1-20; and dispensing the fluid through the self-venting nozzle;

wherein as fluid is dispensed through the self- venting nozzle, the entrained g; escapes to the atmosphere through vent passageways in the self-venting nozzle.

28. The method of claim 27, wherein the fluid enters the vent passageways but does not escape to the atmosphere through the vent passageways.

29. The method of claim 27, further comprising mixing two or more components upstream of the self-venting nozzle to form the fluid.

30. The method of any one of claims 27 or 28, wherein the fluid viscosity is no greater than 500,000 mPa.s.
