Abstract

A spray assembly for dispensing a mixture is provided. The spray assembly includes a connector configured for operable engagement with a first and a second source of component and a source of pressurized fluid, and a tip operably connected to the connector. The tip includes an opening and defines a mixing chamber between the connector and the opening of the tip, and an insert member configured to be received in the mixing chamber. The insert member includes a plurality of radially extending slots on at least one end of the insert. The plurality of radially extending slots is configured to mix the first and second components prior to the mixture exiting the opening in the tip.

Claims

1. A spray assembly for dispensing a mixture, the assembly comprising:

a connector configured for operable engagement with a first and a second source of component and a source of pressurized fluid;

a tip operably connected to the connector, the tip including an opening and defining a mixing chamber between the connector and the opening of the tip; and

an insert member configured to be received in the mixing chamber, the insert member including a plurality of radially extending slots on at least one end of the insert, the plurality of radially extending slots being configured to mix the first and second components prior to the combination exiting the opening in the tip.

2. The spray assembly of claim 1, further including an elongated member extending between the connector and the tip, the elongated member including at least a first lumen configured for fluid communication with the first source of component, a second lumen configured for fluid communication with the second source of component, and a third lumen configured for fluid communication with the source of pressurized fluid.

3. The spray assembly of claim 1, further including a first and a second source of component.

4. The spray assembly of claim 1, wherein the insert member includes three slots.

5. The spray assembly of claim 1, further including a second plurality of radially extending slots on a second end of the insert.

6. A spray assembly for dispensing a fluid, the assembly comprising:

a connector configured for operable engagement with a first and a second source of component and a source of pressurized fluid; and

a tip located on a distal portion of the elongated member, the tip including an opening and defining a mixing chamber between the connector and the opening of the tip, the distal end of the mixing chamber including a plurality of radially extending slots formed about the opening, the plurality of radially extending slots being configured to mix the first and second components prior to the combination exiting the opening in the tip.

7. The spray assembly of claim 6, further including an elongated member operably connecting the connector and the tip, the elongated member having at least a first lumen configured for fluid communication with the first source of component, a second lumen configured for fluid communication with the second source of component and a third lumen configured for fluid communication with the source of pressurized fluid.
