  • Tamper resistant end closure for containers
    Patent number: 4846374
    Abstract: A tamper resistant end closure for a container includes a base for closing an end of the container and a rotor pivotally connected to the base by a hub in the form of a hollow stem extended through a center opening in the base. An annular flange at the lower end of the stem retainably engages a lower surface of the base, and a plug is driven into and bonded within the stem, after the rotor is connected to the base, to inhibit removal of the rotor by preventing radially inward movement of the flange. The rotor and plug may initially be integral, such that an end of the plug is attached by a frangible web to the rotor, at an end of and in alignment with the passage through the stem. The frangible web is broken when the plug is driven into the stem.
