A packaging cup formed from a resilient material has an integrally body having a product reservoir and a lip. The product reservoir includes a flat bottom wall and a continuous side wall integrally joined together about a smooth curve. The side wall extends upwardly from the bottom wall to join the lip. The joint between the lip and the side wall continuously surrounds and defines an opening through the lip to the interior of the reservoir. The lip extends in a plane outwardly from this opening completely around the periphery of this opening. The bottom wall is essentially circular in shape and the opening is essentially squarish in shape. First, second, third and fourth fluted areas are located in the side wall at the corners of the squarish shaped opening. Each of the fluted areas is shaped essentially as a conical surface generated from a cone which is truncated by a plane about a parabolic intersecton of the plane with the cone. With the exception of the first, second, third and fourth fluted areas, the remainder of the side wall is formed as an essentially smooth, continuous surface.
