Abstract
Abstract A shipping carton and end panels therefor and the method of manufacturing same have been disclosed in which extra resistance to crushing is provided by forming the end panels of paper-faced wood veneer which are routed to permit two segments at each end to be folded over and fastened together to form corner posts of triangular cross-section. The bottom, sides and top may be of corrugated paper and are formed with flaps which are glued to the outside faces of the end panels. Alternatively, the bottom, sides and top may be formed of the same material as the end panels. A modification uses a similar technique to form end panels having both vertical and horizontal posts or rails for stiffening in both planes.
