Abstract

A device for applying a mixed component includes first and second component reservoirs, a static mixing nozzle configured to mix first and second components into the mixed component, a component passage disposed between the component reservoirs and the first end of the static mixing nozzle, the component passage disposed to enable the first and second components to flow from the reservoirs to the static mixing nozzle, a spray tip including an air inlet disposed at least partially between the first end of the spray tip and the second end of the spray tip, the first end of the spray tip being disposed adjacent the second end of the static mixing nozzle, a component applicator configured to use air to apply the mixed component through the second end of the spray tip, and a trigger mechanism disposed on the component applicator, and configured to enable application of the mixed component.

First claim

What is claimed is:

1. A device for applying a mixed component, comprising:
first and second component reservoirs, the first component reservoir configured to receive a first component and the second component reservoir configured to receive a second component;
a static mixing nozzle having a first end and a second end, and configured to mix the first and second components into the mixed component;
a component passage disposed between the first and second component reservoirs and the first end of the static mixing nozzle, the component passage disposed so as to enable the first and second components to flow from the first and second reservoirs to the static mixing nozzle;
a spray tip including a first end, a second end, and a regulated air inlet disposed at least partially between the first end of the spray tip and the second end of the spray tip, the first end of the spray tip being disposed adjacent the second end of the static mixing nozzle;
a component applicator configured to use regulated air to apply the mixed component through the second end of the spray tip; and
a trigger mechanism disposed on the component applicator, and configured to enable application of the mixed component.

2. The device of claim 1 , wherein each component cartridge comprises a cylindrical cartridge.

3. The device of claim 1 , wherein each component cartridge further comprises an open filling end slidingly sealed by a cartridge piston seal.

4. The device of claim 1 , wherein the first and second component cartridges have respective cross sectional volumes that are proportional to a predetermined mixing ratio.

5. The device of claim 1 , wherein the spray tip is detachably coupled to the static mixing nozzle.

6. The device of claim 1 , wherein the spray tip is configured to have the mixed component fed therein in a first direction and spray the mixed component in a second direction, the second direction being different from the first direction.

7. The device of claim 6 , wherein the spray tip is configured such that an angle between the first direction and the second direction is 15 to 90 degrees.

8. The device of claim 1 , wherein
the first reservoir and the second reservoir have a ratio of a cross sectional area of the first reservoir to a cross sectional area of the second reservoir that ranges from 1:1 to 1:20.

9. The device of claim 1 , wherein
the static mixing nozzle is disposed on the component applicator.

10. The device of claim 1 , wherein
the static mixing nozzle includes a plurality of mixing elements configured to mix the first and second components.

11. The device of claim 1 , further comprising
a line configured to connect to the spray tip to supply the regulated air for ejecting and atomizing the mixed component.

12. The device of claim 11 , wherein
the trigger mechanism is configured to control the regulated air through the line.

13. The device of claim 1 , wherein the component passage is a flexible hose.

14. The device of claim 13 , wherein
the flexible hose is a first flexible hose of a plurality of flexible hoses, and is configured to be in fluid communication with the first reservoir and the static mixing nozzle, and a second flexible hose of the plurality of flexible hoses is configured to be in fluid communication with the second reservoir and the static mixing nozzle.
