A food container with a rigid base plate formed of a generally planar polymer sheet to have a plurality of stiffening projections extending out of the plane of the sheet, the stiffening projections including a first serpentine projection formed in a segmented, non-linear path and a second, shallower
A food container with a rigid base plate formed of a generally planar polymer sheet to have a plurality of stiffening projections extending out of the plane of the sheet, the stiffening projections including a first serpentine projection formed in a segmented, non-linear path and a second, shallower serpentine projection also formed in a segmented non-linear path, a peripheral gutter and a centrally located oval shaped projection free of interconnection with the first and second serpentine projections, with lands between the stiffening projections forming a generally planar top surface of the base plate. The food container also has a cover of polymer material and the cover and base plate are designed to nest for pre-use storage and stack when assembled in use.
