Abstract: A stackable shipping unit includes a plurality of individual components that may be partially assembled, then packed with items to be shipped. The shipping unit can then be fully assembled, and placed on a pallet. The shipping system may include trays that can be used as either a base or a lid. The unit includes vertical components that are generally U-shaped in plan view, and sized to fit closely within the trays in pairs to form a “H” shape in plan view forming a pair of shipping spaces. Additional U-shaped vertical components can then be assembled to close off the shipping spaces, and a tray can be used as a lid and positioned on top of the vertical components to form an assembled shipping unit.

Abstract: A shipping cradle for seedlings and the like is both nestable and stackable. When stacked, a gap is formed between vertically-adjacent cradles to permit insertion and removal of trays of seedlings, and to permit visual inspection of the seedlings. A drainage system includes a series of channels and openings that prevent water from draining onto seedlings positioned in the lower cradles. The cradles are lightweight, and can be shipped in the nested position to substantially reduce shipping costs.
