  • Patent number: 4981254
    Abstract: A carton having a tubular body is provided with an automatic, or nearly automatic, folding top construction, having triple-thickness handles at opposed ends of the carton, upstanding above the carton closure flaps. Two of the three thickness portions of the handles are hinged to the closure flaps and are automatically formed as the closure flaps are folded to a closed position. The remaining layer of the handles includes a hinged flap swung into position overlying the handle layers. As the third layer is swung into position, locking tabs carried by the third layer are received in recesses on the major closure flaps, thus locking the handles and the major closure flaps in a fully closed position.
