Abstract
A molded carton is provided having a lock system for retaining a cover section in an overlying closed relation with the open top of a base section. The lock system includes a hinged flange mounted on a front segment of the base sections defining the open top. The flange is mounted for limited inward pivotal movement from a normal upright position wherein the flange projects generally upwardly from the front of the base section. The flange is provided with a predetermined number of outwardly projecting protrusions which, when the cover section is in closed position, interlockingly engage a corresponding number of apertures formed in the front wall of the cover section.
