Abstract: A paper pad having a three dimensional image is disclosed wherein the faces or sides of the pad comprise a plurality of paper sheet edges formed into three dimensional surfaces extending from the common planar surface of the side or indenting into said surface. According to one embodiment, the three dimensional surfaces are created through computer numeric controlled (CNC) carving of a compressed side of the paper pad to create an aesthetically pleasing, complex three dimensional design. According to another embodiment, a shaped die is applied to a compressed side of a paper pad under selected conditions of time, temperature, pressure and humidity to deboss a portion of the paper material and produce a three dimensional design in the surface of the compressed side.

Abstract: An article of manufacture includes a first pad of sheets with a plurality of layers where the first pad of sheets perimeter is defined by a first edge, a second edge, a third edge and a fourth edge. The article of manufacture further includes a second pad of sheets with a plurality of layers where the second pad of sheets perimeter is defined by a fifth edge, a sixth edge, a seventh edge and an eighth edge. The first and second pad of sheets are releasably bonded together at the first edge of the first pad of sheets and at the fifth edge of the second pad of sheets by a first adhesive. The first adhesive forms a hinge structure allowing the first pad of sheets and second pad of sheets to rotate about an axis. The second pad of sheets are releasably bonded together at a portion of the bottom side of each layer of the second pad of sheets located at the fifth edge by a second adhesive. The remaining portion of the bottom side of each layer of the second pad of sheets is free of the second adhesive.

Abstract: A reversible and returnable envelope blank of generally cross-shape wherein opposed flaps have non-permanent reusable releasable low-tack pressure-sensitive adhesive at selected places thereon to allow the blank to be folded securely into an envelope by the sender with no adhesive exposed and after unfolding by the receiver reversed and refolded securely into a new envelope still with no adhesive exposed.

Abstract: A stack and dispenser of repositionable adhesive sheets wherein the adhesive is confined to alternate opposite corner areas of successive sheets in the stack so that as each successive sheet is peeled away from the next an advancing line of separation between its adhesive-coated corner area and the next sheet becomes progressively shorter until reducing to a point upon complete separation.
