Abstract

The present invention relates to a blow molded plastic container whose thin wall shoulder portion has a plurality of rib-like protrusions. Each of said rib-like protrusions are configured with multiple radii of curvature having a specifically defined relationship. The protrusions so formed do not adversely affect the integrity of the shoulder portion wall structure and do not distort upon internal pressurization of the container.
