  • Adjustable packing carton for transportation of rectilinear articles
    Patent number: 4899888
    Abstract: A corrugated cardboard packing carton for the transportation of rectilinear articles is provided with cushioned pads to support the lower and upper planar surfaces of the article being transported to protect it from impact. Inserts at each corner of the carton support the article at its edges. The inserts are pre-cut so that portions may be removed to adjust the width of each insert to the exterior size of the article being transported, allowing a single size carton to be used in the packaging of articles of differing dimensions.
