Abstract: A container base for use with a collapsible container includes a base surface coupled to and surrounded by a number of base wall structures. Each of the base wall structures is constructed with an interior and an exterior wall. The interior wall of each base wall is coupled to the base surface. The interior and exterior walls each have substantially smooth surfaces without ribbing or other reinforcement.

Abstract: A container with collapsible sidewalls is provided with a sidewall extension. The sidewall extension increases the height of the sidewall pivot axis above the container base. When the sidewalls are collapsed a portion of the container volume remains for holding, for example, packing material or dunnage.

Abstract: A container having an opening in a sidewall coverable by a hinged gate is described. The hinge for the gate is made by mating two, preferably identical, hinge bodies to thereby insert posts on the hinge into sockets residing, respectively, in the gate and sidewall. The hinge rotates with respect to the gate about a first axis, and rotates with respect to the sidewall about a second spaced parallel axis. The gate, in the opened position, lies flat against the sidewall and is entirely clear from the opening. The gate is latched in its closed position by a clip structure which passes through a first lip of the gate, then through a lip of the sidewall, then through a second lip of the gate.
