ABSTRACT:
A metallic closure for a cylindrical, rectangular or square container comprising a central panel. A part of the panel is adapted for attaching the closure to the end of a container to close the end. The panel has an opening therein and the portion of the metal adjacent the opening is rolled so that the end thereof engages under the inner surface of the panel in a smooth roll such that the free edge is not directly exposed to the contents in the container on which the closure is placed. A composite panel is bonded to the central panel on the outer surface of the central panel. The closure is 100% safe. When the composite panel is removed a residue remains on the outer surface of the metal panel providing evidence of tampering.
