Abstract
A container has a neck formed with projections and a closure assembly for attachment to the neck and movable between a fully released position and a fully closed position. The closure assembly includes a screw cap and an index ring which serves as tamper-evident safety mechanism and is connected to the screw cap via several thin bridge portions forming predetermined breaking points and torn off when the screw cap is released from its fully closed position for the first time for the first time. The neck and the index ring are formed with mutually engaging locking elements (ratchets 36, flexible tongues 34) which are so moved that a tightening of the screw cap from the fully released position into an intermediate position results in at least two of the first locking members of the index ring to engage with the second locking members such that a spontaneous unscrewing and release of the screw cap is prevented while still allowing unscrewing of the screw cap by overcoming a certain retention force applied by the first locking members.
