Abstract
A conventional, relatively soft plastic bottle having a generally cylindrical threaded container neck such as a common polyethylene bottle may be used with a specially formed closure and a fitment as a child resistant container. The closure includes internal ratchets adjacent to the bottom of the skirt which are adapted to coact with corresponding ratchets on the fitment so as to prevent the closure from being unthreaded from the container neck. The fitment engages the container and/or the container neck in such a manner as to lock the fitment against rotation. Preferably the fitment is formed so that it can be moved along the container neck to an operative position in which there is such engagement with the container and/or container neck as the closure is threaded on the container neck.
