A container including a body having a base defining a closed end, a finish defining an opposite open end, and a sidewall between the base and finish. The base includes a support surface defining a reference plane and a contoured base recess extending inwardly from the support surface to a maximum base recess height 'h' from the plane. The sidewall includes a concave rib extending circumferentially around the body. A center of the rib is disposed at a rib height 'h' from the plane. The ratio &#x201c;h:h&#x201d; is between 1:3 and 1:5. The rib includes a radiused transition surface extending from the base to an angled inner surface and having a radius of curvature &#x201c;r&#x201d; of at least 0.10 inches. The angled inner surface has an angle &#x201c;a&#x201d; relative to the plane of between 28 and 80 degrees. A method and mold assembly for making the container are also provided.

An extrusion blow molded plastic container includes a main body portion, a finish portion, and a continuous ledge. The finish portion defines an opening, and includes an upper surface and an outer surface that defines a substantially rectangular shape with rounded corners when viewed in transverse cross-section. The shape of the finish portion when viewed in transverse cross-section is smaller than the shape of the main body portion. The continuous ledge is defined between the outer surface of the main body portion and the outer surface of the finish portion. The ledge has a first width, adjacent to one of the rounded corners of the finish portion, that is greater than a second width that is not adjacent to one of the rounded corners of the finish portion.
