Abstract
A dispenser for lotions, creams and the like has an annular collar in the form of a rotatable cam ring which may be turned to rock an actuator toward a dispensing, open position or toward a closed, non-dispending position. The cam ring has cam tracks that support the actuator when in its open, dispensing position so that finger pressure exerted on the actuator to pump products from the dispenser does not inadvertently rock the actuator toward its closed position. In preferred forms of the invention, a wall section formed as part of a shroud surrounding the actuator is yieldably biased in an inwardly direction, and snaps over the outlet of the actuator to close the outlet channel once the actuator has been pivoted toward its closed, non-dispensing position.
