PCT No. PCT/GB91/01491 Sec. 371 Date May 13, 1993 Sec. 102(e) Date May 13, 1993 PCT Filed Sep. 3, 1991 PCT Pub. No. WO92/05076 PCT Pub. Date Apr. 2, 1992.A box with integral corner reinforcements and a method of making the same is described. The method comprises folding the box from a prescored sheet of material so as to leave a flap adjacent each corner. The flap is prescored and is pushed towards its hinged corner whereby it buckles into a curved shape. The end of the flap is secured by gluing or stapling so as to stabilize the curved shape. The curved shape considerably increases the stiffness and crush resistance of the whole box and may allow may more boxes to be stacked.
