Abstract

A tamper-evident child resistant closure device is provided. The tamper-evident child resistant closure device includes an inner cap having a first set of teeth, an outer cap which fits movably over the inner cap and has a second set of teeth adapted to operatively engage the first set of teeth to facilitate removal of the closure device and inactivatable engagement prevention means for preventing engagement of the first and second sets of teeth. The engagement prevention means functions independently of the configuration of a container on which the closure is used and prevents the removal of the closure device from the container. Once the engagement prevention means are inactivated, the first set of teeth on the inner cap can engage the second set of teeth on the outer cap when the outer cap is displaced axially downwardly with respect to the inner cap. The closure device can be taken off a botttle when the teeth are engaged. The inactivation of the engagement preventing means provides a visual indication that the container has been previously opened or tampered with.
