Abstract
A child resistant closure having a ratchet push and turn mechanism. The ratchet push and turn mechanism includes an over cap disposed over an under cap, each with ratchet teeth in operable engagement. The ratchet teeth of the closure may have a groove. Another groove may extend between adjacent ratchet teeth allowing air to escape from between the under cap and the over cap during the assembly process of the closure.
