<p>A one-piece can body member (30) having a bottom section (34), a generally cylindrical side wall section (32), and an upwardly outwardly inclined connecting wall section (38) connecting the bottom section to the cylindrical side wall section. The bottom wall section (34) has an uppermost concave spherical central panel and a lowermost convexly curved annular support rib (36) which provide an annular lowermost curved support surface for supporting the can body on a flat surface. An upwardly inwardly inclined frusto-conical connecting wall (52) extends between the central panel and the support rib and is connected thereto by curved ends. The connecting wall (38) comprises three frusto-conical straight side walls (54,56,58) which are connected to one another by curved annular reinforcement ribs (60,64). The construction and arrangement enables stacking of cans having different diameter end members.</p> |
