Abstract: Systems and methods are disclosed for foldable containers with improved dumping features. In one embodiment, an example foldable container may include a first container wall, a second container wall coupled to the first container wall at a first joint, the second container wall configured to rotate outwards in a first direction with respect to the first container wall, and a third container wall coupled to the first container wall at a second joint, the third container wall oriented perpendicular to the first container wall. Example foldable containers may include a number of wheels and smooth side panels, where a first cross-sectional area of the foldable container at a lower portion of the foldable container is greater than a second cross-sectional area of the foldable container at an upper portion of the foldable container.

Abstract: Modular transfer units are configured to transport bins or other storage units of standard shapes and sizes between locations. The modular transfer units may be loaded with bins or other storage units having items disposed therein at origins of the items, or at locations where the items are stored, such as fulfillment centers. The modular transfer units may then be mounted to one or more vehicles, such as trailers or rail cars, and transported to another location, where the modular transfer units may be removed from the vehicle, or transferred to another vehicle. The bins or other storage units may be loaded with items that are intended for delivery to a common location. After a bin or storage unit has been unloaded from a modular transfer unit, one or more other bins or storage units may be loaded thereon.

Abstract: Modular containers are formed in a collapsible fashion by flexible or rigid bodies and panels. A size of a modular container may be selected by inflating the modular container to a desired pressure or volume, coupling two or more bodies of the modular containers together, or mating the bodies of the modular containers to common bases or surfaces. The modular containers may be accessed via one or more openings in vertical or horizontal surfaces of such modular containers in order to load items into such modular containers or to unload the items therefrom. The modular containers may be assembled or collapsed manually or automatically, and transported to one or more locations separately or in stacks.
