(57) A lightweight metallic container is disclosed and claimed having a side wall and
an effective rigid bottom wall integral therewith. The side wall and bottom wall merge
to define a first inclined face, the inclined face forming an angle of between about
35" and 45° with respect to the axis of said container, a tapered member is provided
and is integrally formed at the juncture of the side wall and inclined face, the member
having a taper angle in a given range and a given wall taper thickness, an annular
surface integrally connected to the first inclined wall for supporting the container,
a second inclined face integrally connected to the annular surface, and a curved panel
integrally connected with the second inclined face. The curved panel is so formed
that it has a radius of curvature greater than the diameter of the annular surface.
The height of the second inclined face is less than half the height of the first inclined
face. The metallic container as so defined has an improved bottom configuration that
provides for substantial column strength as well as internal pressure stability. One
important feature of the subject bottom configuration is the reduced amount of metal
used to manufacture the container.
