ABSTRACT:
Improved paper clip is formed from a single piece of spring-quality metal wire to have an elongated U-shaped inner loop nested within an elongated U-shaped outer loop. Each loop includes a free leg and a connector leg; the longitudinally-extending leg portions of the free leg and connector leg of each respective loop are of substantially the same length. The U-shaped loops are joined together by an arcuately-curved interconnector extending between the connector leg of each loop. Distal ends of the free leg of each loop are located contiguous to such arcuately-curved interconnector which defines one longitudinal end of the paper clip; with such new configurational and other features, damage to outer surfaces of stacked paper by such distal ends is avoided and clasping force is applied along substantially the full length of such free legs during use of the improved clip.
