Abstract
Molded preform for blow molding a plastic container for pressurized applications, the preform having a base with a multilayer wall for forming a delamination and crack resistant multilayer footed container base. The preform base forming region has an end cap portion with a non-spherical inner wall, including a flattened central section joined by arcuate corner sections to a generally cylindrical outer section. The inner wall sections provide a varying end cap thickness profile which enhances orientation in select portions of the footed container base for improved performance and/or lightweighting of the container base.
