Disclosed is a drinking cup or other container that has a cup body having a generally circular periphery, a bottom, a top rim, and a side wall extending from the bottom to the top rim. The side wall has inside and outside surfaces. It also has a plurality of vertically-oriented, concave-shaped valleys on the outside surface about the periphery of the drinking cup or other container. The drinking cup or other container has a plurality of reinforcing projections on the outside surface. The reinforcing projections are between adjacent valleys. The reinforcing projections are useful in providing additional stiffness to the side wall.
