The cartridge (10) includes a housing for holding the dispenser vial and a telescoping cylinder (18) for compressing the dispenser vial in the longitudinal direction to actuate the vial. The cartridge includes a locking mechanism (43) for locking the telescoping cylinder (18) to restrict its movement and a lever mechanism for releasing the cylinder from the locked position so that a drop is released from the dispenser.
