Abstract: A cost effective binder provides high visual impact by employing a binder cover material which is transparent, and which has imprinted thereon a frame, and which is also provided with a pocket formed of thin plastic material on the inside of the cover. Visual material may be slid into this pocket and may be visible through the front cover of the binder, and is set off and emphasized by the frame formed by the coating.

Abstract: A binder assembly has a partition or intermediate panel separating a ring binder compartment from a storage compartment. The binder assembly includes a spine, a rear cover, a front cover, and an intermediate panel. The rear cover and front cover are pivotally or flexibly mounted adjacent the spine. The rear cover and intermediate panel define a ring binder space for holding pages, closed on one side where the rear and front cover are secured to the spine, and being selectively open on the other three sides. A ring binder is mounted in the ring binder space near the spine. A front cover is pivotally mounted to the intermediate panel. The intermediate panel and the front cover define a storage space closed on one side where the front cover is secured to the intermediate panel and being selectively open on the other three sides. First and second zippers extend around the three open sides of the binder and storage space, respectively, to fully enclose contents of the binder assembly.

Abstract: A double vision binder includes a front cover, a rear cover and a binding portion; a large transparent pocket is formed on the front cover of the binder by a layer of transparent sheet material bonded to the front cover on three sides; and additional smaller transparent pockets are bonded to the first transparent layer, so that a large sheet of background visual material may be inserted in the large pocket, with an overlay of additional visual material in the small pockets. the first layer may extend over the entire outer surface of the binder to provide additional pockets on the rear cover and on the binding portion of the assembly. A plurality of the small pockets may be formed from a single transparent sheet, with pockets separated by bonding lines.
