Abstract: A container packing filler includes an annular roll portion formed by folding one of axially opposite end portions of a stretchable tubular net radially outward and rolling the net toward the other end portion of the net, and a rigid holder portion provided at the other end portion of the net. The holder portion has sufficient axial length and a width greater than the diameter of a center hole of the annular roll portion so that, when the holder portion of the packing filler is squeezed into the center hole of the annular roll portion, the annular roll portion is expanded from the inside thereof by the holder portion and layers of the annular roll portion are unitarily rolled inward.

Abstract: A container packing filler (1) includes an annular roll portion (3) formed by folding one of axially opposite end portions of a stretchable tubular net (2) radially outward and rolling the net (2) toward the other end portion of the net (2), and a rigid holder portion (4) provided at the other end portion of the net (2). The holder portion (4) has a necessary and sufficient axial length and a maximum width (W) greater than the diameter (R) of a center hole (5) of the annular roll portion (3) so that, when the holder portion (4) of the packing filler (1) is squeezed into the center hole (5) of the annular roll portion (3), the annular roll portion (3) is expanded from the inside thereof by the holder portion (4) and layers of the annular roll portion (3) are unitarily rolled inward. Therefore, the bulging of only the outermost layer of the annular roll portion is prevented which may otherwise occur when the holder portion is squeezed.
