Abstract
An improved binder formed of two cover portions made of rigid material joined together with a living hinge. 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.
Claims11
A binder comprising:
- a cover comprised of two portions, a top cover portion and a bottom cover portion, said cover top and bottom portions each having an inside side and an outside side;
- a pocket attached to at least one of said top and bottom portions of said cover on said inside side of said portions;
- said cover and said pocket formed of substantially rigid material;
- said cover having a curved spine in between said top portion and said bottom portions, and free edges opposite said spine;
- said free edges having a distinct curvature and overlapping and interlocking edges so as to readily align and abut one another;
- a pivoting closure fastener for said cover which is semicircular in shape, said closure fastener being attached to one of the two abutting free edges of said cover, and overlying the other free edge of said cover, fitting into a semicircular depression on the other cover and latching;
- said closure fastener being automatically aligned for closure when the covers are aligned, and said closure fastener latching together said first and second cover portions and securing them together mechanically.
A binder comprising:
- a cover comprised of two portions, a top cover portion and a bottom cover portion, said cover top and bottom portions each having an inside side and an outside side;
- a pocket attached to at least one of said top and bottom portions of said cover on said inside side of said portions;
- a ring binder mechanism for holding paper mounted inside said binder;
- said free edges of the cover curving toward each other so as to directly engage and interlock with one-another;
- said spine being curved so as to accommodate the curvature of the ring binder mechanism;
- a closure fastener for said cover, said closure fastener attached to secure the free edges of said cover against separation;
- and
- said closure fastener comprising a latch formed on one of said top and bottom portion free edges, and a mating aperture formed on the other of said top and bottom portion free edges, said latch received by said aperture.
A binder comprising
- a cover comprised of two portions, a top cover portion and a bottom cover portion;
- said covers being pivotally connected to a spine, and having outwardly extending integral free edges;
- said integral free edges being directly overlapping and directly mating with one another preventing relative movement of each of the edges toward or away from the spine of the binder;
- said edges extending toward one another, and each of said edges having portions thereof that overlap the other edge, both in the direction toward said spine and in the direction away from said spine;
- and
- a pivoting closure fastener attached to one of said two edges and pivoting to interlock with said other edge.
