<p>The box with instant binding is for books, bound by rings, spirals or clips. It comprises a rigid rectangular horizontal plate (1) having, on one side, short tongues parallel to each other to form a rack, each tooth of which has two bosses acting as hinges for vertical compartments (5) fitting between the teeth, and which can be tilted. Each compartment comprises two triangular or trapezoidal plates with recesses in which the bosses fit, and joined on one side by a semicylindrical back portion. The latter forms a trough for the insertion of the spirals, rings securing the documents (4) in place.</p> |
