Tray with cellular back and side walls

Abstract:

A tray has a back wall, at least two side walls, a front wall, and a bottom. The side walls have an inner side wall panel and an outer side wall panel, and a gap between the inner and outer side wall panels. The back wall has an outer back wall panel and an inner back wall panel, and a gap provided between the inner back wall panel and the outer back wall panel. The inner back wall panel has first and second side edges, a top edge, and a bottom edge. A first of the inner side wall panels has a back edge, a front edge, a top edge, and a bottom edge. A multilayered corner reinforcing structure couples the back edge of the first inner side wall panel to the first side edge of the inner back wall panel at a first corner of the tray.
