Abstract: A container has a base flange on a base, and a lid flange on a lid. When the container is in a closed position the lid flange and the base flange are in juxtaposition and one of the flange edges defines a flange support surface. A lid surface is spaced above an upper base periphery when in the closed position to define a lid volume, and the base section defines a base volume. The flange support surface extends a first distance such that when the volume of the container is loaded with a rated capacity of product and the container is placed in a standing position on a flat surface using the flange support surface and a front base corner as support elements, a center of gravity of the container generates a moment about an axis of the base corner that biases the container in the standing position.

Abstract: A locking apparatus has a receiving component that includes outer sidewalls extending upward from a first surface to form a raised portion, the raised portion having a receiving surface within a periphery defined by the outer sidewalls, and inner sidewalls extending downward from the receiving surface to form a cavity within the raised portion, the cavity having a cross-sectional area that decreases in proportion to the downward extension of the inner sidewalls, and a first locking structure. The locking apparatus also has an insertion component that includes sidewalls extending upward from a second surface and defining a cross-sectional area that decreases in proportion to the upward extension of the sidewalls, and also includes a second locking structure that is operatively associated with the first locking structure so that when the insertion component is inserted into the receiving component the first locking structure and the second locking structure interlock.

Abstract: A container and a method for forming a container that has a base flange on a base, and a lid flange on a lid. One or both of the base flange and lid flange have a relief pattern. For each flange that has the relief pattern, the relief pattern imparts rigidity in the flange to resist flexure of the flange relative to the portion of the container (the base or lid) to which the flange is attached.
