ABSTRACT:
A paper fastening device for securing a stack of papers in superposed relation without creasing or deformation of the papers is disclosed. The paper fastening device includes a flexible body portion comprising a pair of generally flat, members which are interconnected by flexible hinges such that stacks of paper of variable thicknesses can be inserted therebetween. A clamping member is integrally formed with the body portion and adapted for pivoting movement so as to compress the body portion against the stack of papers and retain them in the clamping member under spring tension. In one embodiment, the device is fabricated entirely from a sheet of flexible plastic material and folded into its function configuration. In this version a conventional steel binder clip is disposed within the clamping member to provide the spring tension for the clamping member. In an alternative embodiment the entire device is molded from a thermoplastic material in its completed configuration. The fastening device is provided in different configurations for attachment to the corner of the paper stack or, in the alternative, to a lateral edge of the paper stack.
