Abstract

A device for applying a mixed component, includes first and second receptacles, a static mixing nozzle, an applicator and an operating member. The first and second receptacles are to receive first and second components, respectively. The static mixing nozzle includes a plurality of mixing elements, has a first end and a second end, and is in fluid communication with the first and second receptacles. The applicator includes a spray tip and an input for pressurized fluid, the spray tip disposed downstream of the second end of the static mixing nozzle and in fluid communication with the static mixing nozzle. The operating member is configured to control the pressurized fluid.

First claim

What is claimed is:

1. A device for applying a mixed component, comprising:
first and second receptacles configured to receive first and second components, respectively, and including first and second apertures, respectively;
a static mixing nozzle including a plurality of mixing elements, having a first end and a second end, and in fluid communication with the first and second receptacles;
an applicator comprising a spray tip and an input for pressurized fluid, the spray tip disposed downstream of the second end of the static mixing nozzle and in fluid communication with the static mixing nozzle; and
an operating member configured to control the pressurized fluid; and
a discharge nozzle disposed between the first end of static mixing nozzle and the first and second receptacles, and being received in the first and second apertures.

2. The device of claim 1 , wherein the discharge nozzle is configured to enable the first and second components to flow therethrough and into the static mixing nozzle.

3. The device of claim 1 , wherein the discharge nozzle is configured to be closed by a plug having two extensions.

4. The device of claim 1 , wherein the input is configured to enable the applicator to use air pressure.

5. The device of claim 1 , further comprising a regulator configured to regulate the pressurized fluid.

6. The device of claim 1 , wherein the operating member is a trigger configured to enable application of the mixed component.

7. The device of claim 1 , wherein the first and second receptacles are first and second cartridges, respectively.

8. The device of claim 1 , wherein the first and second receptacles have respective cross sectional areas that are proportional to a predetermined mixing ratio.

9. The device of claim 1 , wherein a ratio of a cross sectional area of the first receptacle to a cross sectional area of the second receptacle ranges from 1:1 to 1:20.

10. The device of claim 1 , further comprising a handle assembly, and the operating member is disposed on the handle assembly.

11. A device for applying a mixed component, comprising:
first and second receptacles configured to receive first and second components, respectively;
a static mixing nozzle including a plurality of mixing elements, having a first end and a second end, and in fluid communication with the first and second receptacles;
an applicator comprising a spray tip and an input for pressurized fluid, the spray tip disposed downstream of the second end of the static mixing nozzle and in fluid communication with the static mixing nozzle;
an operating member configured to control the pressurized fluid; and
a first piston seal sealing one end of the first receptacle and a second piston seal sealing one end of the second receptacle.

12. A device for applying a mixed component, comprising:
body having a handle assembly;
first and second receptacles configured to be positioned within the body;
a static mixing nozzle including a plurality of mixing elements, having a first end and a second end, and in fluid communication with the first and second receptacles;
an applicator comprising a spray tip and an input for pressurized fluid, the spray tip disposed downstream of the second end of the static mixing nozzle and in fluid communication with the static mixing nozzle; and
an operating member disposed on the handle and configured to control the pressurized fluid.

13. The device of claim 12 , wherein the input is configured to enable the applicator to use air pressure.

14. The device of claim 12 , further comprising a regulator configured to regulate the pressurized fluid.

15. The device of claim 12 , wherein the operating member is a trigger configured to enable application of a mixed component.

16. The device of claim 12 , wherein the first and second receptacles are first and second cartridges, respectively.

17. The device of claim 12 , wherein the first and second receptacles have respective cross sectional areas that are proportional to a predetermined mixing ratio.

18. The device of claim 12 , wherein a ratio of a cross sectional area of the first receptacle to a cross sectional area of the second receptacle ranges from 1:1 to 1:20.
