ABSTRACT:
A thin walled metal container is formed with a bottom wall having a substantially flat central panel connected to a container side wall through an annular rest radius defining an annular support surface for the container. The annular rest radius includes an outer connecting web portion leading into the container side wall and an inner connecting web portion leading into the central panel. In the preferred embodiment, these connecting web portions are permanently joined to each other by welding or adhesive bonding to resist column loading forces acting through the side wall and internal pressure forces acting through the central panel which have the effect of unrolling the annular rest radius. Since these curved opposing portions of the rest radius are immobilized to resist column and internal pressurization, a thinner gauge metal can be used to satisfy design parameters and achieve cost and metal reduction savings. A method of reforming an annular rest radius in the bottom wall of a drawn and ironed container is also disclosed.
