ABSTRACT:
The nestable case is generally box-shaped with four side walls and a base. The side walls include upper fixed wall portions that are rigidly joined together to define a mouth portion of the case. The side walls also include moveable wall portions that are hinged to corresponding foldable sections of the base. When the case is fully loaded with containers the moveable wall portions and foldable sections of the base are in an expanded limit position. When the case is emptied the moveable wall portions and the foldable sections of the base can be moved to a contracted condition, which permits nesting of similarly empty cases. Fully loaded cases in the expanded limit position can be stacked one upon the other or arranged in a pinwheel configuration. A further embodiment of the invention includes provision of a shield at corner clearance openings to protect bruising of any portions of the containers that project from the corner clearance opening.
