ABSTRACT:
A tamper indicating cover seals the closure end of a capped container. The cover is secured to the container by means of a safety band secured within an annular indent in the container. The safety band has visual indicia different from the remainder of the cover so that when a pull tab on the safety band is pulled, the indicia-containing safety band is removed. As the safety band is removed, the remainder of the plastic cover is torn as a result of a helical tear line which may be a stress pattern or a thread embedded in or disposed underneath the plastic cover. The cover is secured to the container by heat fusing or other means between the safety band and the indent of the container.
