<p>A container made of thin sheet metal such as aluminum comprising a cylindrical side wall (3) substantially thinner than the bottom (5) and the bottom being generally a spherical section with nonsymmetrical projections (6) thereon prompting seating areas offset toward the periphery of the bottom wall to provide a stable support for the container and transition areas between the projections and the can bottom which blend into each other in broad curved surfaces such as will not hinder spray applications of coatings onto the can bottom.</p> |
