The present invention pertains to a blow molded plastic container configured to hold food or food-related products, including cheese. In a first embodiment, the container includes extended vertical ribs that have a height that spans at least about ninety-five percent of a height of a lower portion of the container. In a second embodiment, the container includes a reinforced annular leg that is greater than the thickness of the container wall. In a third embodiment, the stacking bead is positioned between the lower and upper container walls, and the lower container wall is inwardly offset from the upper container wall. In a fourth embodiment, the container bottom is reinforced with continuous ribbing as opposed to only partial ribbing incorporated in containers known in the art.

The invention claimed is: 1. A plastic container for storing food, the container comprising, an upper container portion having upper container walls, the upper container further including a rim that defines a container opening, a lower container portion having lower container walls, an annular horizontal stacking bead separating the upper portion from the lower portion said stacking bead having a rectangular shape, and a bottom surface longer than a top surface, wherein the upper container portion, stacking bead and lower container portion are integral with one another, the lower container portion having a container bottom, the lower container portion tapering from the stacking bead to the container bottom and having a plurality of vertical inwardly extending ribs formed thereon and being defined by a container height, wherein each one of the plurality of vertical ribs span at least about ninety-five percent of the container height, each one of the plurality of vertical ribs having a lower end spaced from the container bottom, said plurality of ribs including a first plurality of ribs and a second plurality of ribs, said first plurality of ribs terminating at an upper end spaced from said stacking bead, and having a substantially uniform cross-section along their individual lengths said second plurality of ribs having an upper end contacting the stacking bead and the second plurality of ribs each laterally widening between the stacking bead and the upper end of said first plurality of ribs to form an air passageway for passage of air upon removal of one stacked container from another. 2. The plastic container of claim 1, wherein each one of the first plurality of ribs are defined by a semi-circular cross-sectional shape. 3. The plastic container of claim 2, wherein each one of the plurality of ribs are defined by a radius and are spaced from one another. 4. The plastic container of claim 1, wherein the annular stacking bead further comprises a thickness, a bottom surface and a top surface, the top portion of the lower container wall being inwardly offset from a lower portion of the upper container wall so that, when the plastic container is stacked on top of a lower container, a lower container rim contacts both the bottom surface of the stacking bead and the upper container portion of the container. 5. The plastic container of claim 1, wherein the container bottom includes waffles formed thereon, the waffles spanning substantially the entire container bottom. 6. The plastic container of claim 1, wherein the lower container portion of the plastic container is suitable for nesting inside the lower container portion of a second plastic container when the plastic container is stacked on top of the lower container portion of the second plastic container, the upper container walls of the plastic container extending perpendicular to the rim of the lower container portion and in substantially a same vertical plane as upper container walls of the lower container portion, the upper container portion of the plastic container and upper container portions of additional containers successively nested within one another and stacked on top of the plastic container forming a substantially cylindrical column extending from the lower container portion.
