A first portion may form a first arc centered at the radial axis and having an outward radial direction stemming from the center. A second portion may form a second arc centered at the radial axis and having an outward radial direction stemming from the center, the second arc being opposite to the first arc and being longer than the first arc. A third portion and a fourth portion may be substantially straight lines, one connecting the ends points of the two arcs in the left side and other connecting the end points of the two arcs in the right side.

  • Patent number: 9592647
    Abstract: A modular corrugated container integrates product cushioning with a product support surface formed from corrugated paper and having features that absorb transverse accelerations. The support surface has scored tabs that bend perpendicular to an interior support portion, forming feet that elevate the interior portion relative to a container bottom. The interior portion has perforations that absorb accelerations, such as a perforations formed around the outside perimeter of the location at which a product rests, perforations extending from corners of the support surface towards a central location of the support surface, and perforations at the scoring of the tabs. Voids formed along the tabs remove portions of the feet from contact with the container bottom to encourage constant dissemination of accelerations across the support surface.
