Abstract
Stackable and nestable tote containers folded to an upright configuration defining a generally tapered rectangular receptacle region from a flat blank of double faced corrugated plastic. The tote containers may be nested within one another in an aligned column, or may be selectively stacked on top of one another at an orientation of between 45 and 90 relative to one another, such that the receptacle region of the lower tote container is partially obstructed but may still be accessed. In one embodiment, a rectangular cross stacking tote container having a length greater than its width may be nested within a like tote container, or elevated to a position completely above the like tote container, rotated 90 in either direction such that apertures in the base and side wall panels are aligned with upwardly projecting exposed segments of the metal rim of the lower tote container, and lowered into a stacking engagement thereon. In a second embodiment, a generally square twist stacking tote container may be nested within a like container, or elevated to a position near the top of the like tote container, and rotated 45 in either direction such that apertures defined in the corners of the u…
