Moulded plastics paper clip - consists of flat tongue attached to rectangular frame, with detents to grip paper

摘要

The paper clip is made from injection moulded plastics and consists of a rectangular frame (1) with a flat tongue (2) fitting inside this frame and attached to one end of it. This tongue has two rounded projections (31) on each of its long sides (25). These projections are spaced on either side of a similar projection which projects from the inside of the rectangular frame. Each set of three projections forms an undulating passage which grips the sheets of paper placed between the tongue and frame.
