An improved binder formed of two cover portions made of rigid material joined together with a living hinge is disclosed. A closure flap with a second living hinge joins the free ends of the cover opposite the binder spine. An improved method of attaching a pocket to the binder is also disclosed. The use of such a technique on rigid polypropylene material allows roll feeding of materials, eliminates the need for a chipboard, allows existing printing and sealing machinery to be employed in the manufacture of the binder, and provides improved durability and aesthetics at a low cost. One cover portion may be adapted with number design features to properly align one cover portion relative to the other cover portion. A pocket formed of rigid material may also be coupled to one of the cover portions.

[ We claim:] [1.]1. A binder comprising:a covercomprised of two portions, a top cover portion and a bottom cover portion, said top and bottom cover portions each having an inside side and an outside side, wherein said bottom cover portion has an outwardly extending free edge;a pocket having at least three outer edges, wherein said pocket is welded to at least one of said top and bottom cover portions of said cover on said inside side of said portions along at least one outer edges of said pocket;said cover and said pocket formed of substantially rigid material;said cover having a spine in between said top portion and said bottom portions, and free edges opposite said spine;a latch having a plurality of rings coupled to the bottom cover portion of said cover;a guide protruding from said spine, wherein said guide is position to associate with one of the plurality of rings of said latch, wherein the guide positions the spine in a predetermined position to align the top cover portion relative to the bottom cover portion;said top cover portion having a tooth, wherein said tooth has a predetermined width;said bottom cover portion having a pair of guiding teeth adapted to receive said tooth between said pair of guiding teeth, wherein said pair of guiding teeth are separated by approximately the same distances as said predetermined width of said tooth, wherein when the top cover portion is closed relative to said bottom cover portion, said tooth of said top cover portion and said pair of guiding teeth of said bottom cover portion align the top cover portion relative to said bottom cover portion to close properly, wherein said tooth in between said pair of guiding teeth substantially prevents the top cover portion from moving side to side relative to the bottom cover portion, wherein the pair of guiding teeth protrude from the inside side of the bottom cover portion to form a gap between the pair of teeth and the outwardly extending free edge.
