摘要： A continuous method for closing and sealing a carton having a tubular body and end closure flaps hingedly connected to the opposite ends of the body walls. One of the end closures includes a panel which is cut and scored and folded upon itself to define a double thickness carrying handle immediately adjacent the body wall to which such panel is connected, together with a closure flap portion extending in prolongation of the reversely folded part of the handle. The tubular body of the carton is vertically disposed and advanced in a path of travel with the panel incorporating the carrying handle rearmost. A single stationary sweep means is utilized to first infold the leading closure flap of the handle forming end closure and then outfold the handle parts relative to the carton body, the outfolding of the handle parts acting to automatically infold the attached closure flaps, whereupon the remaining closure flaps at the handle forming end are infolded with the interposition of adhesive between the juxtaposed flaps. The carton is then filled and its remaining end closure flaps closed and sealed.
