ABSTRACT:
The present invention is a container and closure device, which includes the container, a collar ring and a cap. The container has a neck, an open top and a horizontal retainer track for affixing a collar ring thereto. The collar ring has a circular inside wall with a horizontal track for attachment to the track of the container so as to be horizontally and freely rotatable thereabout. The collar ring also has a top with a ledge thereon for frictionally engaging and retaining a cap, and has at least one cut out on the ledge to permit a cap to be inserted and removed from the collar ring. The cap has semi-flexible walls and has at least one protrusion which corresponds to and has a geometry of adequate size 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 and geometry 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 protrusions and the cut outs are in alignment for lift up removal of the cap from the collar ring.
