Abstract
The invention contemplates selectively openable closure means that is tamper-proof, in the sense that a correct sequence of two deliberate and independent movements of two parts is necessary in order to achieve access to the contents of the bottle or the like which is protected by the closure. The specific construction that is described involves a bottle with a neck having a circular opening, and a closure cap having a cylindrical wall to overlap and lock to the outer surface of the neck. The closed end of the cap has an axially projecting stiffly yieldable annular section which engages a chamber at the circular neck opening, in the course of closing the bottle. The nature of the lock is such as to avoid 'plugged' closure and to compliantly preload the yieldable engagement, utilizing the resilient action to retain the lock and to establish a liquid seal of the bottle contents.
