Abstract: This disclosure relates to a container body side seam construction wherein a metal body blank is provided with adhesive strips along opposite edges thereof, followed by the forming of hooks at such opposite edges. Thereafter, the body blank is formed in a conventional body-making machine so as to first interlock the hooks and then, while the hooks are engaged, flattening the hooks to form an interlocked side seam wherein the adhesive strips are in tightly clamped relation with respect to one another and portions of the side seam.
