ABSTRACT:
Three packing cases are disclosed each having a tray and a top portion so assembled that abutting marginal edges of the side and end panels of the tray and cover are adapted to support one case stacked upon another without relying upon the columnar strength of the contents of the case, and where the tray and cover individually have a vertical height significantly less than the height of the product contained in the case. The tray and cover are fabricated from a multiple ply corrugated cardboard material and conventionally formed from generally flat rectangulr blanks with uniquely arranged end flaps such that the flaps can be glued to the tray and nevertheless easily disassembled for purposes of displaying the contents of the tray after the cover has been removed.
