Abstract

Reinforced corrugated cartons on the order of 35 to 50 inches in height and somewhat greater in length and width are provided with an inside tubular rectangular liner and a bottom pad fitted down inside the liner and adhesively secured to the inside bottom flaps of the carton. Disposed entirely peripherally around the carton sidewalls or the tubular liner and extending upward for a distance from substantially the bottom thereof on the outside is a belt of non-woven backing material with yarns laminated thereon and extending peripherally laterally completely therearound. The yarns may be of any material which exhibits minimal elongation under tension. The belt backing material may typically be of non-woven polyester and approximately 20' or so in width extending upward from substantially the bottom of the carton or liner, and the yarns may typically each be 1800 denier formed of approximately 250 fiberglass filaments and arranged with a side by side density of 20 to the inch at the bottom reducing to 5 to the inch at the top and graded in between. The belt is wrapped around the carton or liner with the backing material thereagainst and held thereto with several glue spots with the ends of the belt brought into abutment on the surface of the carton or liner. A patch of the same material is then glued firmly over the butt joint with the filaments of the patch facing and adhered to the filaments of the belt.
