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.

An apparatus for transporting articles comprising: a transporting well having a generally planar polygonal bottom and a plurality of walls, each of said plurality of walls depending from a first side of said bottom to an upper extremity; and a substantially rigid bead structure joining each of said plurality of walls substantially at its respective upper extremity; said bead structure defining a peripheral channel adjacent said plurality of walls outboard of said well, said channel being bounded by said plurality of walls, by a web extending substantially from said respective upper extremities, and by a skirt depending from said web; said skirt extending a first distance from said web at preselected sections of said channel, and said skirt extending a second distance from said web at other sections of said channel, said first distance being greater than said second distance; said preselected sections being located at each of said plurality of corners.
