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.

Abstract: A lift system includes a base and a vertical structure from which a plurality of tines projects. The tines are configured to engage a lower surface of a plurality of dairy trays within a stack of dairy trays in order to facilitate lifting part of a stack of dairy trays to access or remove a tray that is lower in the stack. In one embodiment, a plurality of pairs of tines are movable from a low position where they can engage a plurality of stacked trays to a raised position where there is space between each of the adjacent trays.
