Abstract
A pump dispenser includes a dispenser head rotatable relative to a locking ring for a lock-down feature during shipment. The lock-down feature requires a greater torque to initially rotate the dispenser head from the lock-down position, and a lesser torque to further rotate the dispenser head to a use position. The lock-down feature incorporates an interference between the dispenser head and locking ring, either inside the dispenser head, on an outer periphery of the dispenser head, or between threads connecting the dispenser head and locking ring.
