Abstract
A paper stack protection device is disclosed which has a triangular shaped pocket designed to accept a corner of a stack of papers. A staple through the pocket and the corner of a paper stack secures the pocket to the stack of papers. The top and bottom sides of the pocket provide a long fold back line along the hypotenuse of the front and back sides of the pocket so that the first and last sheets of the stack of papers are inhibited from tearing away from the stack.
Claims4
A paper stack protection device comprising
- a pocket of triangular shape, said pocket having top and bottom sides of substantially identical right triangle shape, said top and bottom sides being placed in registration with each other with their edges which form a right angle being joined and with their edges forming the hypotenuse not being joined, thereby creating an opening into said pocket,
- said pocket adapted to fit about a corner of a stack of papers and to accept a fastener through both sides of said pocket and said papers with the result that tope and bottom papers in the stack are inhibited from tearing away at said fastener, wherein said top and bottom sides have their edges which form a right angle joined by one or more convolutions, thereby allowing said top and bottom sides to expand so as to accept a thick paper stack.
A combination comprising
- a paper stack protection device including a triangularly shaped pocket having top and bottom sides of triangular shape, said top and bottom sides each having a right triangle shape, said top and bottom sides being in registration with each other such that their edges which form a right angle are joined, with the hypotenuse edges of said top and bottom sides not being joined, thereby creating an opening into said pocket via said hypotenuse sides of said pocket,
- a paper stack having one of its corners inserted into said pocket, and
- a staple through said top side of said pocket, said corner of said paper stack and through said bottom side of said pocket.
