ABSTRACT:
A composite can construction wherein the body wall, adjacent either one or both cap receiving ends thereof, is inwardly compressed to reduce the outside diameter of the tubular body while maintaining the inside diameter. The compression, reducing the thickness of the body wall, also densifies the material thereof without affecting the interior of the container or the structural integrity thereof. The compressed area extends along the length of the container body a distance sufficient to project substantially beyond the bead formed as a metal end cap is seamed to the body, thus providing a recess for facilitating accommodating of the driving wheel of a conventional can opener. The formed bead, utilizing the pre-compressed body portion and the denser material thereof, is relatively narrower and stiffer than the bead conventionally obtained upon the sealing of a metal end cap to a composite tubular body.
