Nozzle closures which are mounted for pivoting movement from a closed to an open position are used with a spray dispensing device. In the open position, the nozzle closure moves away from the spray nozzle on an actuator and a spray opening in a surrounding wall, allowing fluid to dispensed through the nozzle, as the actuator is depressed. In the closed position, the nozzle closure pivots into a position where a projection enters at least partially into the spray nozzle. The projection acts to seal the spray nozzle against air, thereby preventing drying of any fluid in the nozzle and reducing the chance that the spray nozzle will become clogged. The projection also serves to provide resistance against depression of the actuator, thereby providing a locking function for the actuator to prevent accidental discharge from the spray nozzle. The sealing finger completely covers a spray opening in a wall surrounding the actuator.
