Closure having reinforced pull tab |
摘要 |
A metallic closure for a cylindrical, rectangular or square container comprising a central panel which has a portion thereof 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 including a layer of plastic is bonded to the central panel and the outer surface of the central panel by heat fusion of plastic. The composite panel includes a tab that is formed integrally thereof and initially is folded back upon itself bringing the surfaces of the tab which bear the plastic into contact so that the two portions of the tab are bonded to one another to provide a double strength tab.
