Sheet binder

摘要

A binder made from a single piece of injection molded plastic material. The binder includes an elongated dorsal part having a first lateral side and a second lateral side. A plurality of fingers are formed integrally with and extend from the first side of the dorsal part. Each of the fingers has a free end. The fingers curl toward the second side to form rings which extend through holes in the sheets to secure the sheets on the binder. A plurality of teeth are formed integrally with and are spaced along the second side of the dorsal part. The free ends of the fingers extend close enough to the first side of the dorsal part to prevent the sheets from unintentionally sliding out of the binder. Optionally, the punch binder includes a spine removably disposed along a length of the dorsal part for preventing the fingers and teeth from separating. The spine can be attached to both the dorsal part and to the ring-shaped fingers or to only one of the two.
