Abstract: Apparatus and method for closing and sealing lined taper top cartons wherein the cartons are advanced in a path of travel with their liner mouths open, the end walls of said carton and the opposite ends of the liner being simultaneously deflected inwardly and the front and rear carton walls and the opposite sides of the liner mouth concurrently displaced toward each other to juxtapose the upper edges of the front and rear walls with the liner mouth flattened therebetween, the flattened liner mouth then folded upon itself to form a double thickness mouth, the folded liner mouth and an end closure flap hinged to the carton rear wall then being simultaneously folded over the upper edge of the carton front wall and the folded closure flap secured to the front wall of the carton.

Abstract: An improved end closure for a prelined carton formed from a knocked-down tubular carton structure, the end closure comprising an opposing pair of innermost closure flaps and an opposing pair of outermost closure flaps, the innermost flaps each being diagonally scored to define a triangular tab portion at one end thereof, the triangular tab portions being adhesively secured to the mouth of the liner mouth as an incident of erecting the carton, the tabs being folded inwardly by the liner mouth as it is expanded and flattened for sealing, the infolded tabs assisting in positioning the liner mouth for sealing and also serving to facilitate the infolding of the ends of the sealed liner mouth as an incident of infolding the innermost closure flaps to overlie the end of the carton body.

Abstract: A paperboard carton having a large capacity pouring spout formed in a relatively narrow end wall, the pouring spout being fabricated as the carton is tubed into knocked-down flat-folded condition, the carton having an opposing pair of side walls and an opposing pair of relatively narrow end walls, with a glue flap hingedly connected to the side edge of one of the side walls, the glue flap being juxtaposed and adhesively secured to the inner surface of the adjacent end wall to form a tubular carton body; an outwardly displaceable pouring spout tab is formed in the end wall to which the glue flap is juxtaposed, the pouring spout tab being of generally rectangular configuration and having one of its side edges lying along the line of articulation between the end wall and the other of the side walls, the underlying glue flap being enlarged to extend across the full width of the end wall in the area of the pouring spout tab, the enlarged portion of the glue flap having an extension hingedly connected to its outerm

Abstract: A one-piece paperboard carton for relatively heavy articles, the carton having a reclosable top closure and a self-contained carrying handle formed in one of its body walls, the body wall in which the handle is formed being reinforced in the area of the handle by a plurality of thicknesses of paperboard one of which comprises a flap extension carried by one of the top closure flaps, means being provided to secure the flap extension in handle reinforcing position when the top closure is in the fully closed position.

Abstract: A one-piece hinged lid carton formed from a flat-folded carton structure having a tubular body and end closure flaps, the tubular body having an additional body panel and a detachable glue flap which define the top panel and front panel of the lid, with selected end closure flap defining the side panels of the lid, the remainder of the end closure flaps defining the end walls of the carton body, the top wall of the carton body having a dispensing opening therein which is closed by the lid, and preferably the carton will be provided with a protective liner as an incident of its fabrication, with the liner adhered to the undersurface of the top wall in the area immediately surrounding the dispensing opening, thereby facilitating the puncturing of the liner for removal of the contents of the carton through the dispensing opening.
