  • Tamper indicating cover
    Patent number: 4624378
    Abstract: A tamper indicating cover seals the closure of a cap container. The cover is secured to the container by means of a safety band secured over an annular protrusion on 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 controling 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 the plastic cover. The cover is secured to the container by heat fusing or other means between the safety band and the protrusion on the container.
