  • Patent number: 4379519
    Abstract: A conventional stiff paper bag adapted to be maintained in an open or folded condition is maintained in the open position by a pair of disposable U-shaped stiffeners which mount over the upper edges of opposing side panels of the bag. The stiffeners preclude creases in the side panels from tending to relax the bag into the folded condition. The stiffeners are preferably slightly longer than the horizontal dimension of the side panels to force the bag mouth into the open position.
