Self-securing box construction

Abstract

A self-securing box is formed from a blank which is cut, scored, folded and secured to define an open ended tube having a top with foldable outer end flaps, a bottom with foldable inner end flaps and sides with foldable end tabs. Each of the tabs adjacent the outer end flaps have an acute angular edge portion therein. The respective tabs, inner flaps and outer flaps at opposite ends of the tube are folded successively 90 degrees into engaging registry. The sides of the outer flaps define lock edges which are included at an acute angle so as to normally overlap the tab edge portions and are adapted for manual flexing interlocking inward projection so as to retainably engage interior portions of the adjacent tab at the edge portion. A hollow preformed simulated ribbon of stiff material is rectangular in longitudinal cross-section and is formed as a closed loop so as to longitudinally extend around the top, bottom and folded end flaps. The sides of the inner end flaps are inclined at an acute angle whereby when said tabs and flaps are folded over and secured together, the box has the appearance of being wrapped.
