ABSTRACT:
An educational book device having pages made from a plurality of flat sheets of printable material provided with a special configuration when in a flat form prior to assembly into the book form. The special configuration is such that the flat sheet may be folded in a manner so as to provide an extending flap portion. Additional fastening or securing strips may be provided for the flap in order to positively hold the flap together. A preformed notch on the outer corner edge of the extending flap permits the flap to be inserted into the pocket formed at the rear of the adjacent flap when the sheets are bound together in book form. Appropriate edges of the flat sheets are normally prepunched for reception of spiral-type binding material, but may also be secured together in conventional stitched and glued book fashion. One embodiment of the book is in the shape of a sphere, while additional embodiments are diamond-shaped, triangular-shaped, and rectangular cylindrical-shaped when assembled. Additional means for interlocking the flap of one page with the pocket formed at the rear of the flap of the adjacent page in various embodiments are also provided.
