Abstract

A cup liner for a cup of a spray gun includes a fluid reservoir portion that defines a reservoir and includes a divider portion dividing the reservoir into two or more compartments. Each compartment contains a fluid to be dispensed by the spray gun and keeps the fluids separated from fluids held by other compartments. In addition, a fitting for a spray gun includes two or more inlet interfaces and an outlet interface. Each inlet interface couples to a fluid source and the outlet couples to the spray gun such that the fitting provides fluid communication between each fluid source and the spray gun. This permits the spray gun to spray a mixture of the fluids.

Claims

1. A cup liner for a cup of a spray gun, the cup supporting two or more fluids to be dispensed by the spray gun, the cup liner comprising:

a fluid reservoir portion configured to be received in an interior of the cup, the fluid reservoir portion configured to contain the two or more fluids, the fluid reservoir portion defining a reservoir configured to hold the two or more fluids, the fluid reservoir portion including a divider portion having one or more divider walls dividing the reservoir into two or more compartments, each compartment configured to contain one of the two or more fluids, the one or more divider walls separating each compartment such that each compartment is configured to separate the fluid contain therein from the fluids contained in the other compartments when the reservoir is filled with the two or more fluids, wherein the fluid reservoir portion is configured to be fluidly connected to the spray gun when the fluid reservoir portion is received in the cup such that the spray gun can draw at least a portion of each fluid from each of the two or more compartments to spray a mixture of the two or more fluids.

2. The cup liner of claim 1, wherein the fluid reservoir portion includes at least three compartments.

3. The cup liner of claim 1, further comprising a liquid paint component in each of the two or more compartments.

4. The cup liner of claim 3, further comprising a tamper-evident seal that must be broken to access the liquid paint components in each of the two or more compartments without damaging the fluid reservoir portion of the liner.

5. The cup liner of claim 4, wherein the fluid reservoir portion includes a lower wall and a cylindrical outer wall extending upward from the lower wall, the lower and outer walls defining the reservoir, and wherein the one or more divider walls are connected to the lower and outer walls.

6. The cup liner of claim 5, wherein the outer wall has a longitudinal axis and the at least one divider wall includes three divider walls, the three divider walls all connected together along the longitudinal axis, the three divider walls dividing the reservoir into three compartments.

7. The cup liner of claim 1, further comprising an interface coupled to the fluid reservoir portion, the interface configured to be coupled to the spray gun, the interface configured to selectively close each compartment of the fluid reservoir portion to inhibit the two or more fluids contained in the reservoir from mixing and from being drawn by the spray gun and the interface configured to selectively open each compartment of the fluid reservoir portion to permit the spray gun to draw at least a portion of each fluid from each of the two or more compartments to spray the mixture of the two or more fluids.

8. The cup liner of claim 7, wherein the interface is releasably coupled to the fluid reservoir portion.

9. The cup liner of claim 7, wherein the interface defines a passageway in fluid communication with each of the two or more compartments, the passageway providing fluid communication between the spray gun and each compartment of the fluid reservoir portion when the interface is coupled to the spray gun.

10. The cup liner of claim 9, wherein the interface includes a valve disposed between the passageway and the two or more compartments, the valve having an open configuration and a closed configuration, the valve closing the two or more compartments of the fluid reservoir portion to inhibit the two or more fluids contained in the reservoir from mixing and from being drawn by the spray gun when the valve is in the closed configuration and the valve opening the two or more compartments of the fluid reservoir portion to permit the spray gun to draw at least a portion of each fluid from each of the two or more compartments to spray a mixture of the two or more fluids when the valve is in the open configuration.

11. The cup liner of claim 7, wherein the interface sealingly engages the fluid reservoir portion to inhibit the two or more fluids contained in the reservoir from mixing.

12. The cup liner of claim 1, in combination with at least one of the cup and the spray gun.

13. A fitting for a spray gun to connect the spray gun to two or more fluid sources, each fluid source having a fluid to be dispensed by the spray gun, the fitting comprising:

two or more inlet interfaces, each inlet interface defining an inlet to the fitting, each inlet interface configured to be coupled to a respective one of the two or more fluid sources such that the fluid of each fluid source is in fluid communication with the inlet defined by the respective inlet interface; and

an outlet interface defining an outlet in fluid communication with each inlet, the outlet interface configured to be coupled to the spray gun, wherein the outlet interface is configured to provide fluid communication between the spray gun and the two or more fluid sources when the outlet interface is coupled to the spray gun and the two or more inlet interfaces are coupled to the two or more fluid sources such that the spray gun can draw at least a portion of each fluid from each of the two or more fluid sources to spray a mixture of the two or more fluids.

14. The fitting of claim 13, further comprising a valve disposed between the two or more inlet interfaces and the outlet interface, the valve fluidly connecting each inlet with the outlet when the valve is in the open position and closing each inlet to inhibit the fluids from the two or more fluid sources from mixing and being drawn in the spray gun when the valve is in the closed position.

15. The fitting of claim 13, wherein each inlet interface includes threads to threadably connect to one of the two or more fluid sources.

16. The fitting of claim 13, further comprising a cup connection portion configured to couple the fitting to the cup.

17. The fitting of claim 16, wherein the cup connection portion includes threads to threadably connect to the cup

18. The fitting of claim 17, wherein the two or more fluid sources are two or more bags that are supported by the cup, each bag containing one of the fluids therein, wherein each inlet interface is configured to couple to one of the two or more bags.

19. The fitting of claim 13, in combination with at least one of the two or more fluid sources, the cup and the spray gun.

20. A method of spraying two or more fluids from two or more fluid sources with a spray gun, each fluid source having one of the two or more fluids, the method comprising:

accessing the two or more fluids from the two or more fluid sources, wherein accessing the two or more fluids comprises breaking a tamper-evident seal associated with each fluid source;

coupling each of the two or more fluid sources directly to a single fitting;

coupling the fitting to the spray gun, wherein the fitting provides fluid communication between each fluid source and the spray gun after each of the two or more fluid sources is coupled to the fitting and the fitting is coupled to the spray gun; and

spraying a mixture of the two or more fluids with the spray gun.
