Abstract
Abstract A drawn and ironed container having a reduced neck around an upper open end has a bottom profile which exhibits excellent strength characteristics and nests with an end double-seamed to the open end of the container. The bottom profile includes a center spherical dome surrounded by a U-shaped annular portion defining a lower support surface for the container. A joining segment is integral with the container side wall and the U-shaped annular portion includes a first annular arcuate portion having an exterior radius and a second annular arcuate portion having an interior radius.
