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.
Claims3
In combination, a bag adapted to be maintained in an open position or a folded position, the bag having front, rear, and opposing side panels defining a rectangular horizontal cross-section when the bag is in the open position, upper edges of said panels defining a bag mouth, the opposing side panels having the intermediate vertical creases therein, and
- stiffening members, each having a length greater than the horizontal dimension of the side panel of the bag, removably mounted over the upper edges of the opposing side panels to maintain the bag mouth in the open position.
