Abstract
A dispensing head for a squeeze bottle sprayer includes a rotatable valve. The rotatable valve has both an air control notch and a fluid control notch. Upon rotation of the valve, the notches cooperate to vary the amount of air and or fluid discharged by the dispenser. The density of the stream may therefore be varied.
