ABSTRACT:
A one-piece blank construction for a flip-lid box includes a rectangular bottom panel, rectangular top panel, panels bridging between the bottom and top, and two flip-lid panels foldably connected to one of the components of the respective side walls. The overall "footprint" of the blank is small because the blank is approximately rectangular, thus effecting the maximum saving of material. The one-piece construction is easy to set up, cuts the wastage of material, and increases strength so as to allow a smaller material thickness to be utilized.
