  • Tamper evident container
    Patent number: 4643329
    Abstract: A tamper evident package for dairy products and other foods and consumables. A conventional container and lid are included, along with a plastic disk which is wedged in place on top of the lid with the edge of the disk fitting in a channel in order to prevent removal of the lid. The disk has a frangible center section which must be broken away before the disk can be removed to release the lid. The presence of the disk intact on the lid indicates that the container has not been opened, while absence or mutilation of the disk provides visible evidence of tampering.
