Abstract:
A method for closing a carton having mutually perpendicular side and end walls and an inner major overlap flap and an opposed outer major overlap flap each having dimensions more than half the width dimensions of said carton and each foldably connected along one side via a longitudinal fold line to it adjacent of said side walls and a pair of opposed minor flaps each foldably connected along one side via a transverse fold line to its adjacent of said end walls, each said minor flap having a length corresponding to a that of said end wall of said carton to which it is connected and a width extending from said transverse fold line to a free edge of said minor flap significantly shorter than length of said longitudinal fold line, comprising positioning said carton with said major and minor flaps in planes substantially parallel to said end or side wall to which it is connected, moving said carton with said flaps so positioned along a path in a direction parallel to said planes in which said major flaps are positioned, retaining said major flaps in their respective said plane, applying adhesive to an inner surface of said outer major flap and to an outer surface of said inner major flap while said flaps are so retained, folding said inner major flap into a folded position substantially perpendicular to said side wall to which it is connected, folding a trailing one of said minor flaps trailing in said direction of movement into a folded position overlying said inner major flap as said carton is moved long said path, holding said inner major flap and said trailing minor flap in said folded positions and folding a leading of said minor flaps leading in said direction of movement over said inner major flap as said carton is moved along said path, holding said trailing and said leading minor flaps and said inner major flap in folded positions and folding said outer major flap into a folded position overlying said minor flaps and said inner major flap.
