Disclosed is a locking assembly for use with a pump type dispenser to dispense material from a container. The assembly includes an actuator including at least one timing pin and a locking mechanism coupled to the actuator for limiting movement of the actuator until the timing pin is properly aligned with the locking mechanism. Alignment is achieved by rotating the actuator a first predetermined distance in a first direction and subsequently rotating the actuator a second predetermined distance in a second direction.

[ I claim:] [1.] A pump-type dispenser for dispensing material from a container, comprising:an actuator including a timing pin, wherein the timing pin extends downwardly from the actuator;and a locking mechanism coupled to the actuator for limiting movement of the actuator to dispense material from a container until the timing pin is properly aligned with the locking mechanism, wherein alignment is achieved by rotating the actuator a first predetermined distance in a first direction and subsequently rotating the actuator a second predetermined distance in a second direction, the locking mechanism including;a first disk including at least one hole, wherein the timing pin passes through the at least one hole such that the first disk rotates with the actuator;a second disk secured to a support surface of the container, the second disk including a hole through which the timing pin passes when the hole in the second disk is aligned with the hole in the first disk; andlocking structure associated with the first disk and the second disk, permitting the actuator to rotate to align the hole in the first disk with the hole in the second disk;wherein, when the hole in the first disk and the hole in the second disk are not aligned, the timing pin is prevented from passing through the hole in the first disk and the hole in the second disk, and the actuator is prevented from moving up and down to dispense material from the container, the locking mechanism further including;a third disk positioned between the first disk and the second disk, the third disk including a hole through which the timing pin passes when the hole in the third disk is aligned with the hole in the first disk; anda locking structure associated with the first disk, the second disk, and the third disk, permitting the actuator to rotate in a first direction to align the hole in the second disk with the hole in the third disk and to rotate in a second direction, opposite the first direction, to align the hole in the first disk with the hole in the third disk;wherein, when the hole in the first disk, the hole in the second disk, and the hole in the third disk are not aligned, the one timing pin is prevented from passing through the hole in the first disk, the hole in the second disk, and the hole in the third disk, and the actuator is prevented from moving up and down to dispense materials from the container.
