The present invention is a container closure device, which includes a container, a collar ring and a cap. The container has a neck, an open top and a horizontal retainer track thereon for affixing a collar ring thereto. A collar ring affixed to a track of the container has a plurality of cut outs on a ledge to permit a cap to be inserted and removed from the collar ring. The cap has has a plurality of bosses which correspond to and are sized to freely move through the cut outs of the ledge of the collar ring and, when the cap is so inserted and rotated, of adequate size to cause frictional engagement and to cause simultaneous rotation of the cap and the collar ring and to prevent removal of the cap from the collar ring, except when the cap and the collar ring are held separately and are rotated relative to one another such that the bosses and the cut outs are in alignment for lift up removal of the cap from the collar ring. Corresponding bosses and cut outs have different lengths and depths so that one boss cannot slip through a non matched cut out.
