ABSTRACT:
The present invention involves a child resistant closure for containers with threaded necks. It involves a cylindrical inner and outer cap which engage with one another by ratchets to close the closure. These ratchets do not engage when an attempt is made to open the closure. The inner cap has threads on its inside and is adapted to non-removably receive the outer cap in that the outer cap is rotatably engaged therewith. The outer cap is non-removably but rotatably mounted on and engaged with the inner cap. At least two biased keyway slots are used and each may be located either on the outside of the inner cap or the inside of the outer cap. There are at least two biased keyway protrusions, one corresponding to each slot, and each protrusion extends toward its corresponding keyway slot. Each is located on which ever of the inner cap and outer cap does not contain the corresponding slot. There are indexes on each of the caps and when they are aligned, the keyway protrusions ad their corresponding keyway slots will be aligned. The user will align the indexes or indicia and then lift up so that the protrusions fit into their keyway slots. In this manner, the outer cap engages the inner cap so that they are simultaneously rotated for opening. Upon closure ,the protrusion will be pushed or dropped out of the slot and the ratchets will engage for proper closure.
