Abstract: 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.

Abstract: Lid and container assembly in which lid features and securement strips cooperatively provide the assembly with tamper resistant and tamper indicator features. Specifically, the lid is structured so that one or more simple securement strips, such as adhesive tapes, or even a non-peripherally wrapped shrink band (e.g., one that is wrapped around the assembly from top to bottom), can be used to secure the lid to the container at one or more locations. The securement strip(s) inhibit egress into the container at the taped or secured regions. In the meantime, an egress barrier incorporated into the lid also inhibits egress into the container through untaped or unsecured regions of the assembly. Thus, the assembly is tamper resistant around the entire juncture between the lid and container even though only part of the juncture is covered by the securement strip(s).
