Abstract
A bottle having an open neck with an outer surface. The neck includes a thread finish formed on the outer surface thereof having a predetermined thickness along its length. A cap having an inner surface releaseably threadable on the neck includes at least one pivotable arm with a thread thereon facing the inner surface of the cap and selectively engageable with the thread finish on the neck when the cap is threaded on the bottle. The arm is pivotable between a first position where the thread is positioned adjacent the inner surface of the cap and a second position where the thread is moved outwardly away from the inner surface. The thread is captured below the thread finish when the cap is threaded on the neck to lock the cap on the bottle. The thread finish includes at least a first reduced thickness region sized to permit the thread to bypass the reduced thickness region when the arm is pivoted to its second position to permit the cap to be removed from the bottle.
