ABSTRACT:
A box blank for a produce box has four side panels which are hinged together along score lines. An extension flap adjacent one of the side panels is wrapped around and glued to the panel at the opposite end of the blank. The side two major and two minor panels each have an appropriate length flap attached to one edge which is unscored and is to be folded into the top, and a flap on the other edge which is appropriately scored for folding to form the bottom of the box. More specifically, two minor and two major panels are attached to edges of the side panels, at a scored hinge line. 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. In assembling the bottom of the box, the major flaps are first bent in toward the bottom and then the triangular corner flap on each major flap is bent outward to lie against the outside surface of the major flap. The free triangular corner of the minor flap, which is preferably truncated for each easy folding, is now folded underneath, and then the minor flap is folded down against the bottom surface being formed. Glue can now be applied in a single straight stroke across the exposed half of the triangle scored on the minor flap.
