Each minor panel has a triangle scored thereon, the base of the triangle being the hinge line with the side flap. One end of each major panel is attached to a minor panel; the other end of each major panel has a score line, roughly defining a triangle which will overlap 1/2 of the triangle scored onto the minor flap.
