A fiberboard box formed from a blank (20), which includes side panels (24 and 28), also top and bottom flaps (40, 42, 44 and 46), with a pair of outer end panels (26 and 30). Mating inner overlapped end panels (48 and 50) produce a double fiberboard thickness on each end. Each corner contains a doub
A fiberboard box formed from a blank (20), which includes side panels (24 and 28), also top and bottom flaps (40, 42, 44 and 46), with a pair of outer end panels (26 and 30). Mating inner overlapped end panels (48 and 50) produce a double fiberboard thickness on each end. Each corner contains a doubled vertical reinforcement (64) at an equal bisecting angle integrally formed from each outer end panel and adjacent side panel. A diagonal corner reinforcement (68) is formed from each overlap end panel and is angularly bent to span between the end and side panels and is also contiguous with the doubled vertical reinforcement. The diagonal and doubled reinforcement combination in each corner is attached together with glue where they touch each other, creating a rigid weight bearing corner permitting other like boxes to be stacked on top. Optionally, a number of stacking tabs (52) are formed in the end panels with mating recesses (54) maintaining alignment when the completed boxes are stacked.

A fiberboard box with reinforced corners formed from a flat blank board, that is scored, slotted, and slitted, the box comprising: a near side panel integrally formed from the blank folded upwardly at a right angle, a left outer end panel integrally formed from the blank contiguous with the near side panel folded upwardly at a right angle, a far side panel integrally formed from the blank contiguous with the left outer end panel folded upwardly at a right angle, a right outer end panel integrally formed from the blank contiguous with the far side panel folded upwardly at a right angle, closure means connecting said near side panel and said outer end panel into a rectangle, a left inner bottom flap integrally formed from the blank contiguous with the left outer end panel folded inwardly toward the panels, a right inner bottom flap integrally formed from the blank contiguous with the right outer end panel folded inwardly towards the panels, a near outer bottom side flap integrally formed from the blank contiguous with the near side panel folded inwardly therefrom overlapping the inner bottom flaps, a far outer bottom side flap integrally formed from the blank contiguous with the bar side panel folded inwardly therefrom overlapping the inner bottom flaps, the flaps jointly forming a bottom, bottom attaching mean joining the bottom flaps together into a structural bottom, a left inner overlap end panel integrally formed from the blank contiguous with the left outer end panel folded inside the left outer end panel producing a double thickness end, a right inner overlap end panel integrally formed from the blank contiguous with the right outer end panel folded inside the right outer end panel producing a double thickness end, a near top flap integrally formed from the blank contiguous with the near side panel folded inwardly to produce a first half of a top, a far top flap integrally formed from the blank contiguous with the far side panel folded inwardly to produce a second half of a top, joining means fastening the top flaps one with the other where they butt together forming a top, a doubled corner vertical reinforcement formed integrally from the outer end panels and adjacent side panel, distending into the box at an equal bisecting angle from each right angle intersection of the panels forming a double wall corner structural reinforcement, a plurality of diagonal corner reinforcements integrally formed from the overlap end panels further, each diagonal corner reinforcement having an inside overlapped fastening tab distal therewith, angularly bent to span between the end and side panels contiguous with the doubled corner vertical reinforcements and the fastening tab attached to the side panels with mounting means, the doubled reinforcements further forming triple structural reinforcing corners permitting additional boxes to be stacked thereon without corner crushing.
