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. While the adhesive strips are so held, the side seam is heated so as to effect bonding of the adhesive strips. The principal advantage of the container body side seam construction is that no external means is required to hold the side seam portions in their proper positions while the adhesive strips are being heated and then permitted to set.
