Abstract
Package stuffing material is formed by rolling strips of relatively rigid paper stock to cylindrical bodies. The strip is rolled so that the outer longitudinal edge is adhered to the outer surface of the cylinder while the inner end hangs free. The inner end extends between a 90.degree. to 180.degree. arc along the inner wall and when the cylindrical is pressed its edge engages the wall substantially limiting the degree of distortion.
Claims3
Package stuffing material comprising a plurality of hollow bodies adapted to fill a volume greater than the sum of their individual volumes, each body comprising a strip of shape retaining paper stock material rolled into a cylinder having its outer end adhered adjacent its longitudinal edge to the outer surface of the cylinder and having its inner end freely extending along the inner wall of said cylinder so as to be circumferential slidable therealong to place its free inner longitudinal edge in engagement with the inner wall on application of a radial force to the cylinder.
