ABSTRACT:
A composite end panel is adhesively bonded to the sidewall of a can or similar container with the end panel periphery overlying a portion of the sidewall outer surface. A plastic band or hoop is placed on the sidewall, overlapping the edge of the end panel, and shrunk in place through the application of heat. The band seals the cut edge and prevents wicking while insuring that the end panel is retained in position. A fillet of sealant may be applied to the inside of the container at the juncture of the sidewall and the end panel.
