Abstract
An apparatus for transporting articles comprising a transporting well having a generally planar polygonal bottom and a plurality of walls, each of which walls being joined substantially at its upper extremity by a substantially rigid bead structure which defines a peripheral channel adjacent the plurality of walls outboard of the well. The channel is bounded by the plurality of walls, by a web extending substantially from the upper extremities of the walls, and by a skirt depending from the web. The skirt extends a greater distance from the web in the vicinity of the corners of the well than elsewhere. The apparatus includes a channel-filling structure substantially at the center of each section of longer skirt length for precluding jamming during stacking, and stand-off ridges on the outboard side of each wall for limiting the expanse of contact area between the walls and abutting planar surfaces.
