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.
