ABSTRACT:
A child resistant container closure assembly having a container neck and a container closure where the container closure has an inner part and an outer part. A first set of castellations are located on the inner part. A second set of castellations are located on the outer part and arranged to inter-engage the first set of castellations on the inner part when the outer part is moved axially towards the inner part to permit full torque to be applied to the inner part. A set of resilient blades extend from a first of the inner and outer parts towards a second of the inner and outer parts, the resilient blades bearing against the second of the inner and outer parts to urge the outer part axially in a direction away from the inner part such that the first and second sets of castellations are normally held out of inter-engagement. Each of the resilient blades having a remote end and having an abutment surface at the remote end, each of the resilient blades having a longitudinal cross-section which tapers towards the remote end, and a profile at an acute angle between each resilient blade and the closure part from which the resilient blade extends being radiused. At least one resilient blade is provided with at least one reinforcing rib extending longitudinally along the blade.
