ABSTRACT:
A locking device includes an internal closure cap having a threaded bore for engagement with the threads of a container or opening. The closure cap is structured with an upstanding stem which is open for discharging liquid. The outer surface of the stem has a rib gear section. A sleeve member superimpose the stem of the closure cap, whereby seals the tip. An annular shell surrounds the closure cap, and the sleeve member, controlling the engagement of the closure cap. However the sleeve member is structured with internal and external gearing formed to engage the outer ribbing of the closure cap and an internal ribbing within the annular shell, when raised vertically; whereby, a twisting action of the annular shell can be transferred to the closure cap for engaging and disengaging a threaded neck. A set of cylinders with marked flanges are positioned through the annular shell, superimposing the sleeve member, restricting its upward movement. The release position of the sleeve member can only be facilitated by rotating the flanges to a predetermined alignment.
