ABSTRACT:
Looseleaf notebooks, report folders, and similar stationary items incorporating a deep pocket extending over the length of the item. A flexible transparent notebook of this design incorporates a pair of thermoplastic sheets which are cut to the appropriate dimensions and heat-sealed to form a pocket which is coextensive with the outer notebook cover. A ring binder support is fastened to the center of one of the plastic sheets. Such notebooks, report folders, or the like may advantageously incorporate an auxiliary pocket affixed at one of the outer edges to permit folding along this edge. The notebook may be provided with an opaque cover by inserting one or more opaque sheets within the large outer pocket.
