The present invention pertains to a plastic container configured to hold food or food related products, including cheese. The container includes upper and lower container walls separated by an integral annular stacking bead and an integral container bottom featuring an exterior side having a plurality of annular and radial reinforcing ribs. The lower container wall features vertical ribs defined by smooth curves that span at least ninety-five percent of the lower container height. The stacking bead is inwardly offset from the upper wall of the container in order to facilitate the nesting of the container within the lower portion of another container and to prevent the containers from being wedged within one another when they are nested. The arrangement of the annular and radial ribs on the exterior side of the container bottom provide increased strength to the container and prevent the container from deforming when filled.
