ABSTRACT:
In a liquid dispenser having a vertically reciprocable plunger, the plunger is immobilized by use of a locking system. The locking system comprises a turret collar which is mounted on the cap of the dispenser. A discharge channel member contains a discharge passage which communicates with the vertically reciprocable plunger and the member extends laterally substantially beyond the circumference of the turret collar. The collar has a vertical slot therein adapted to receive the discharge channel member and to permit full vertical movement thereof in conjunction with the operation of the liquid dispenser. A locking groove in the turret collar communicates with the vertical slot and is adapted to retain the discharge channel member, therefore immobilizing the vertically reciprocable plunger, after rotation of the turret collar or rotation of the discharge channel member in a horizontal direction.
