A molded plastic container having an open top and an outwardly smooth sidewall wherein the interior surface of the sidewall is characterized by a plurality of parallel vertical flutes defined by shallow, smooth concavities joined by flat columns of uniform thickness wherein the ratio of the circumferential diameter of each concavity to the circumferential width of a column is about 8:1. The outside surface of the container is smooth and molded with two integral, vertically spaced, circumferential rings for added hoop strength. The container exhibits a high stacking strength-to-weight ratio. The preferred material is HDPE.
