One piece hanging file
Abstract:
A one piece hanging file made from a continuous web of a flexible sheet material. In one embodiment, small loops are heat-welded at intervals along the strip creating channels or hems for removable hangers. Larger loops between the channels become the file pockets. In another embodiment spring clips clamp small loops of the strip and have notched overhanging ends to engage the support rails. In another embodiment, laminated film is welded directly to the edges of the hanger strips. In all embodiments the filed objects, such as compact discs, rise smoothly out of the looped file pocket when a hanger is lifted. In all embodiments, an opening or aperture made in the center of the looped bottom prevents round media such as CDs from accidentally rolling out of the pocket.
