ABSTRACT:
A pull tab type opening device is formed upon an insert metal strip mounted atop the can's lid. The opening device is affixed to and covers an opening in the can's lid by inter-locking rim portions on the strip and lid. Accordingly, the lid may be formed of a less expensive metal, such as steel, while the metal strip, occupying a small portion of the lid, is formed of the more expensive aluminum. Since the percentage of the dissimilar metal, aluminum, in a can is very small in comparison to steel, a used can may thereby be processed as a single metal, steel.
