Abstract

This invention is a paperboard box and a lid having a paper with a design placed on the outside surface. The paper is held in position by being glued to the inside of the finished carton. The box or lid has four squared corners. The finished decorative box has adhesive on the interior panels and may be shipped in flat form and erected at or near the point of use. Because the paper is thick it is difficult to form square corners on the box or lid. The box or lid has a paperboard web between a side panel and an end panel which is folded to make a square corner. It has been found that a slit can be cut in the paper bisecting the corner which will allow the paper to be folded without bunching and making an attractive square corner. Once the slit is cut in the paper the side and end panels can be folded to produce a square corner without any bulging paper. The bulging paper is not attractive as a gift-wrap box and also may prevent the locking of the corner as required to form a box and lid with square corners.
