ABSTRACT:
An airless application system. The system includes a primary product container and a sprayer in fluid communication with the primary product container. The primary product container may include a relatively rigid canister, a collapsible bag within the relatively rigid canister, and propellant between the bag and the relatively rigid canister. The sprayer includes a sprayer tip; a primary product chamber for holding a primary product to be dispensed through the sprayer tip, the primary product chamber in selective fluid communication with the sprayer tip, the primary product chamber having an outlet; a secondary product chamber outlet in selective fluid communication with the sprayer tip; a manual control which travels through a range, the range including a first position and a second position; and a valve assembly responsive to the manual control, wherein when the manual control is in the first position, the primary product chamber outlet is closed; and wherein when the manual control is in the second position, the primary product outlet is open. The invention also involves a method of airless spraying of a primary product and a secondary product.
