A reinforced corrugated cardboard container formed from a folded up corrugated cardboard blank (100) includes a bottom formed from a central generally rectangular area (110) of the blank and four walls formed by folding upward flaps (120, 130) extending from the rectangular area of the blank, four corners each formed by folding over an extension piece (160) of a folded upward flap (120, 130), which extends in size beyond the rectangular area and attaching the extension piece (160) to the folded upward flap of an adjacent wall of the container. One or more of the corners are reinforced by additionally folding the extension piece of the folded upward flap forming the corner to form an indentation to the container wall it is attached to, such that a void (145) is formed by the extension piece of the flap between the resulting wall and a virtual straight wall defined by the central generally rectangular area.
