Abstract
Abstract A tamperproof package including a container sealed with a turnoff or twist-off type closure. The container neck includes a threaded upper portion and a lower portion having anti-rotation lugs spaced therearound. A retaining ring lined with plastisol is positioned over the lower portion of the container neck so that the plastisol flows around the anti-rotation lugs to prevent rotation of the ring. A closure lined with plastisol is then pressed over the container neck so that the plastisol flows into contact with the threads on the container neck. A tamperindicating tape or band is positioned around the package so as to overlap and be in contact with both the closure and the ring. The tamper-indicating tape must be removed before the closure may be rotated out of engagement with the container.
