Compartmentalized paint cup with selector valve for spray guns

For use in combination with a conventional or automated hand-held spray gun:

• A. a detachable paint cup comprising at least two vertical compartments for containing a different liquid coating material in each said compartment for spray application;
• B. a detachable lid to cover said compartmentalized paint cup to form an air tight seal over each separate compartment in said cup when the lid is closed, said lid further comprising:
• 1. at least two vertical aspirator tubes projecting downwardly through the proximate center of said lid causing each tube to extend nearly to the bottom of one compartment, the forward tube being slightly bent forward towards the direction forward of said spray gun to contact a minimal level of liquid as the cup is tilted forward;
• 2. vent means providing an air passageway to each of the said compartments;
• 3. a valve housing permanently attached at the top of said lid for receiving each aspirator tube and further comprising a rotatable valve spool with an essentially triangular gate means to selectively permit fluid flow from a single aspirator tube through a common passageway into an attached spray gun.
