Abstract
A box construction includes an integral bottom panel, opposite side panels, opposite end panels and a pair of partial top panels, wherein the opposite end panels extend a full depth dimension of the box construction, and wherein each of the opposite end panels is provided with a minor flap portion at an upper end thereof. The minor flap portions are adapted to be folded to a substantially horizontal orientation such that the minor flap portions will be engaged by a respective ones of the partial top panels when the box is closed. A reinforcing end panel is adhered to interior sides of each of the opposite end panels, each reinforcing end panel having a pair of stacking projections extending from an upper edge of the reinforcing panel. Each reinforcing end panel is also formed with a pair of cut-outs along a lower edge thereof which cooperate with apertures in the bottom panel to provide stacking recesses adapted to receive stacking projections of an identical underlying box in a stacking arrangement.
