Reinforced container and method of making

A method of reinforcing corrugated cardboard containers against rupture and excessive deformation by utilization of a substantially non-lengthwise extensible wide fabric belt having a pair of laterally spaced apart side edges and a pair of opposite ends and being of a type comprising a non-woven backing material to one surface of which is adhered a parallel array of yarns extending lengthwise of said belt, said yarns being of a type which exhibits minimal elongation under tension and are spaced closely together in parallel array at one edge of the belt and are relatively widely spaced at the other edge of the belt, and are continuously graded in spacing density between the two edges of the belt, said container being of the type having sidewalls, a top closure and a bottom closure, consisting of the steps of,

• (a) disposing said fabric belt lengthwise completely peripherally around the carton sidewalls with the edge with the more closely spaced yarns positioned substantially at the bottom of the container sidewalls and the edge with the more widely spaced yarns positioned upward therefrom, and with the backing material disposed flatwise against the surface of the carton sidewalls,
• (b) adhesively securing the belt backing material to the carton sidewalls in the position aforesaid,
• (c) securing the opposite ends of the belt against relative movement in belt loosening directions by adhesively securing to the belt a patch made of the same material as the belt with the yarns of the patch and belt being disposed in parallel facing relation and sandwiched between the backing material of said belt and patch.

• (a) disposing said fabric belt lengthwise completely peripherally around the tubular liner with the edge with the more closely spaced yarns positioned substantially at the bottom of the liner and the edge with the more widely spaced yarns positioned upward therefrom, and with the backing material disposed flatwise against the surface of the liner,
• (b) adhesively securing the belt backing material to the liner in the position aforesaid,
• (c) securing the opposite ends of the belt against relative movement in belt loosening directions by adhesively securing to the belt a patch made of the same material as the belt with the yarns of the patch and belt being disposed in parallel facing relation and sandwiched between the backing material of said belt and patch,
• whereby, said liner is ready for installation into said container.
