The present invention relates to reinforced box structures. A blank for forming a pre-stiffened box structure is provided. The blank comprises a box portion having a base and side panels for providing a box structure, a stiffening panel extending integrally from a given one of the side panels, and a line of weakness delimiting the stiffening panel from said given side panel. The blank is operable into a pre-stiffened configuration wherein the given side panel is folded to position the stiffening panel to substantially overlap and be secured to the base of the box portion. When the folded side panel is pivoted about the line of weakness, a free end of the side panel is biased away from the secured stiffening panel and thereby separates from the stiffening panel along the line of weakness.
