US Patent 10023346 Swirl bell bottle with wavy ribs

An apparatus is provided for a container comprising a base, a bell, a sidewall between the base and the bell, a neck and a finish which define an opening to an interior of the container, and a shoulder between the sidewall and the bell. Strap ribs extend from a central portion of the base and terminate at the sidewall. The strap ribs cooperate with vertically aligned recessed columns of the sidewall to resist bending, leaning, crumbling, or stretching along the sidewall and the base. An inwardly offset portion of the sidewall is disposed between each pair of adjacent recessed columns. The inwardly offset portions of the sidewall are configured to resist outward bowing of the sidewall due to internal pressure of contents within the container.
