ABSTRACT:
A tamper-proof container for over-the-counter drugs or the like includes a cylindrical plastic bottle which tapers to a narrow neck. An annular angled depression is molded into the bottle neck. A two-part closure includes a cap ring onto which is molded an annular angled projection sized and positioned to mate with the angled depression in the bottle neck when the cap ring is snapped over the bottle mouth. A hinged cap is attached to the cap ring and has a plurality of tamper tab projections connected thereto via a like plurality of frangible tear regions. The tamper tab projections mate with corresponding tamper tab depressions in the cap ring when the hinged cap is closed. After the bottle is filled, a tamper-evident seal is adhered over the mouth of the bottle and the cap ring is snapped over the bottle mouth, enclosing the tamper-evident seal. The cap ring is then ultrasonically welded to the bottle neck and the cap is ultrasonically welded to the cap ring via the tamper tabs. The result is a tamper-proof container.
