Abstract: 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 “hbrmax” 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 “hr” from the plane. The ratio “hbrmax:hr” 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 “r1” of at least 0.10 inches. The angled inner surface has an angle “a” relative to the plane of between 28 and 80 degrees. A method and mold assembly for making the container are also provided.

Abstract: Container including a body having a compartment defined therein, the body including a base portion defining a closed end, a finish portion defining an open end opposite the base portion, and a sidewall between the base portion and the finish portion. The base portion 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 “hbrmax” from the reference plane. The sidewall includes a concave rib extending circumferentially around the body, wherein a center of the concave rib in side cross-section is disposed at a rib height “hr” from the reference plane, wherein the ratio of the maximum base recess height to the rib height “hbrmax:hr” is between 1:3 and 1:5. The concave rib in side cross-section includes a radiused transition surface extending from the base portion to an angled inner surface, the radiused transition surface has a radius of curvature “r1” of at least 0.

Abstract: 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.

Abstract: An extrusion blow molded plastic container includes a main body portion and a finish portion that defines an opening. The finish portion has an upper surface and an outer surface on which a snap bead is defined. In order to prevent saddling of the upper surface, a plurality of grooves is defined in the outer surface, each of the grooves passing through the snap bead. In addition, the main body portion has an outer surface that defines a substantially rectangular shape with rounded corners when viewed in transverse cross-section. The outer surface of the finish portion also has 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. A ledge is defined between the outer surface of the main body portion and the outer surface of the finish portion.
