Abstract
A pump dispenser head has a lockdown feature to prevent unintended dispensing during shipment. Releasing the lock-down feature requires increased torque compared with typical dispensers, allowing the dispenser to be shipped with less packaging while still preventing leakage of the contents.

A dispenser assembly comprising:
- a dispenser head comprising
- a fluid inlet;
- a fluid outlet;
- a depending skirt;
- and
- a locking rib on an inner surface of the depending skirt;
- and
- a chaplet comprising
- a top wall;
- a skirt extending downward from the top wall;
- and
- a locking ramp with a proximal end attached to the top wall, and a distal end extending above the top wall and free to flex with respect to the top wall;
- wherein the dispenser head is rotatable relative to the chaplet between a lock-down position and an unlocked position;
- and
- wherein placing the dispenser head in the lock-down position requires a first torque to rotate the dispenser head and move the locking rib past the locking ramp, and returning the dispenser header to an unlocked position requires a second torque, and the second torque is greater than the first torque.
