ABSTRACT:
An article carrier having bottom, top, side and end walls interconnected to form an enclosure of rectilinear configuration and having a pair of spaced apart hand hole openings formed in the top wall includes a reinforcing strip secured to the inner surface of the top wall and between the hand hole openings. End extensions which may or may not be adhered project from each end of the reinforcing strip and are folded into flat face contacting relation with the end walls respectively and are secured thereto. The fold lines between the end extensions and the cooperating end edges of the reinforcing strip are debossed so as to protrude inwardly and mate with a complementary embossed area which is encased by torque relief slits thereby reducing the tension along the outer surfaces of the fold lines between the top wall and the end walls so as effectively to strengthen the load bearing elements of the carrier top wall.
