Abstract
One piece, molded, looseleaf books adapted to hold paper sheets with punched holes therein, said books having a spine with a longitudinal, vertical cavity in the rear, outer face, a removable, snap-in or press-in spine insert fitted in said cavity, said book optionally having a pivotable lower segment adapted to swing about a horizontal, transverse hinge to provide a diagonal leg serving as an easel-like stand for the open book, a second, longitudinal, vertical cavity in the inner face of said spine, a snap-ring assembly mounted in said second cavity, a front cover panel and a rear cover panel pivotally connected to opposite longitudinal edges of said spine by living hinges, and one or more shallow cavities in the front face of said front cover to receive graphic insert panel(s). Still another innovation pertains to the shape of the rear, outer face of the spine. When molded, as in the present invention, this face may be planar, transversely arched or rounded either inwardly or outwardly, ribbed longitudinally or transversely, etc. Further, the front and rear cover panels may be of any desired outline, e.g., rectangular, triangular, polygonal, circular, oval, etc. simply by providing such shape in the molding die.
