Abstract
A container seam includes an additional vertical section of metal and a corrugated outer surface for providing sufficient vertical seam strength to resist the crushing force exerted by an opener drive gear. An end member is provided with an overhang having a segment thereof folded back parallel upon another segment of the overhang. After a seaming process, the folded segments are vertically oriented and provide increased vertical strength. During said seaming process, the outside part of the seam is provided with vertical corrugations to further increase vertical strength.
