ABSTRACT:
A generally circular container of generally cup shape having a side wall and a bottom wall, the side wall in axial cross section of the container being at its upper portion straight and extending at an angle inwardly in the downward direction relatively to the axis of the container or perhaps more aptly defined as an inverted frusto-conical portion of uniform thickness and being at its lower portion curved downwardly and inwardly or defining a curvilinear surface of progressively decreasing diameter, the lower portion of the side wall being of uniform thickness equal to the thickness of the upper portion of the side wall, the lower portion of the side wall merging into the bottom wall of planar disciform configuration merged to the side wall by a smooth rounded curved juncture, the container having an annular, dependent foot extending downwardly from the bottom wall spaced inwardly from the lower extremity of the side wall. The upper portion of the side wall is preferably of somewhat greater vertical extent than the lower portion of the side wall and the vertical dimension of the depending foot is such that when two or more containers are nested the side walls are slightly spaced. The lower portion of the side wall desirably merges into the bottom wall at a curved corner which is tangent to the bottom of the container, such curved corner defining an arc of a circle of substantially less radius than that of the lower portion of the side wall.
