Abstract (en)
[origin: WO9511170A1] A flexible, self-supporting shaped plastics bag has an open end surrounded by a rigid flange, a tubular or frusto-conical side wall depending from the flange to form a generally tubular portion and a base joining the side wall through a radiused portion, the side wall being provided with a plurality of reinforcing ribs extending longitudinally along the tubular portion and through the radiused portion. The thickness of the ribs increases progressively from the open end portion of the container through the radiused portion at which the ribs form elongated knuckles reinforcing the junction of the side wall and base and enabling the container to stand on its base.
