A binder for papers, photographs, or other sheet-like materials is provided with a cover having one or more window openings defined therein. A flat, transparent protective sheet is located in contact with the inside surface of the binder cover and a backing sheet overlies the protective sheet. The backing sheet is secured to the peripheral margin of the protective sheet, and elsewhere as required, to delineate at least one, and preferably a plurality of pockets. The pockets are formed between the backing sheet and the protective sheet. An elongated slit in defined through the backing sheet behind each pocket created. The peripheral edges of the backing sheet are permanently secured to the inside surface of the binder cover. Photographs or other flat display materials may be inserted into the pockets formed between the backing sheet and the protective sheet through the elongated slits. The pockets are delineated so that they are aligned with the window opening in the cover. The photographs or other display materials may thereby be viewed through the window openings from the outside through the transparent protective sheet. Selected display materials may be inserted and withdrawn from the pockets through the elongated slits in the backing cover.
In combination, a binder cover formed of a stiff plastic material having an inside hidden surface and an outside exposed surface and at least one window opening with an enclosed perimeter defined therewithin, a flat, transparent plastic, protective sheet residing in direct contact with said inside surface of said cover and having a peripheral margin that extends about said perimeter of said window opening, and a flat, plastic backing sheet having a peripheral margin about its perimeter and wherein at least one access slit is defined in said backing sheet at said window opening, and said backing sheet resides in direct contact with and is fused to said protective sheet by interior lines of heat sealing that at least partially surround said enclosed perimeter of said window opening and said peripheral margin of said backing sheet and said peripheral margin of said protective sheet are fused directly to each other and to said inside surface of said cover at peripheral lines of heat sealing so that said protective sheet is located between said cover and said backing sheet, whereby said access slit permits insertion and withdrawal of flat display objects between said protective sheet and said backing sheet.
A binder having a cover formed of a stiff plastic material with at least one display window, wherein said cover is formed with inside and outside surfaces and with at least one window opening defined within its perimeter, further comprising a flat, transparent, plastic protective sheet and disposed in direct contact with said inside surface of said cover, wherein said protective sheet has a peripheral margin that extends beyond said at least one window opening, and a flat plastic backing sheet disposed in direct contact with said protective sheet and having a peripheral margin that extends beyond and surrounds said at least one window opening, and said backing sheet resides in direct contact with and is fused to said protective sheet by interior lines of heat sealing that at least partially surround said window opening and said peripheral margin of said backing sheet and said peripheral margin of said protective sheet are fused directly to each other and to said inside surface of said cover with said protective sheet located between said cover and said backing sheet, and at least one access slit is defined through said backing sheet to permit insertion and removal of flat objects in between said protective sheet and said backing sheet for viewing through said at least one display window.
A binder having a cover with at least one window opening defined therethrough wherein said window opening has an inner peripheral boundary and said cover is formed of a stiff plastic material with inside and outside surfaces and further comprising:
A binder according to claim in 17 wherein said peripheral lines of heat sealing seal said peripheral margin of said backing sheet throughout to said peripheral margin of said binder cover.
