Abstract: A pour spout construction particularly adapted for longer shelf life barrier paperboard containers, such as containers of the gable top type. Barrier containers often carry products and the interior surfaces of the former are lined or covered with a barrier layer. According to this invention a dispensing opening is formed in the paperboard and the major barrier layer extends across and covers this opening. An externally threaded pour spout, attached to the container, carries a threaded cap which normally closes the pour spout. This cap carries an innermost annular skirt whose lower edge is adhered to that barrier layer portion which spans the dispensing opening. When the cap is unscrewed from the spout, the innermost annular skirt carries a part of the barrier layer away from its normal, sealing position, thus rupturing the barrier layer and permitting dispensing of the container contents.

Abstract: A pour spout fitment for a flat top or a gable top paperboard container. A flat strip of rigid plastic material is bent over upon itself to form upper and lower strips integrally hinged together. The lower strip carries a plug coplanar with it, the upper surface of the plug adhered to a part of the lower surface of the upper, hinged strip. The lower surface of the plug is sealed to a portion of a barrier extrusion which covers the entire interior surface of the container, the plug being aligned with a dispensing opening through the paperboard, the opening also covered by the barrier extrusion material. For initial opening and dispensing of the container contents, the upper strip is pulled upwardly, carrying with it the plug and the ruptured barrier extrusion material adhered to the plug. The surfaces of the lower strip over which the contents of the container flow during dispensing are thus protected from contamination at all times except during dispensing.

Abstract: A container top closure integrally formed from plastic polymer material as by injection molding. The closure is adapted to be attached to the upper end of a container for granular or other pourable material. A single plastic member, such as polypropylene, or polyethylene, is provided with a dispensing opening, the opening having an integral skirt downwardly depending from three sides of its periphery, to define a first dispensing opening surface. A closure flap, integrally formed with the member which defines the top closure, carries two sealing surfaces which cooperate with complementary surfaces formed around the dispensing opening. The sealing surfaces provide increased moisture entrance resistance across the dispensing opening.

Abstract: An end closure construction for a tube-type container formed from a single paperboard blank, the blank having an extruded barrier layer coating on one surface thereof. The carton has at least one end closure which is flat and defined by end closure panels. To prevent excessive overlapping of paperboard layers at the center of the flat, closed carton end, each one of a pair of facing end closure panels is centrally recessed along its free edge. An abutment tongue on one of the facing end closure panels is bordered by a pair of recesses. Each of the recesses is spanned by the extruded barrier layer coating. The abutment tongue bears against the oppositely positioned barrier layer to form gussets, in a controlled manner, from the barrier layer.

Abstract: A one piece blank is provided which may be erected into a generally hollow self-supporting food carton. The blank includes a base panel having first and second opposing score line edges, and first and second upright panels which are hingedly connected to corresponding scored edges of the base panel. The base panel also includes connecting side edges which extend between the opposing scored edges. Each upright panel includes bottom edge sections which extend outwardly from inwardly spaced locations on the connecting side edges. Cuts are provided which extend from the intersection of the connecting side edges and the bottom panel sections to the scored base panel edges. The carton is assembled by pivoting the first and second upright panels about the scored base edges, and attaching the upright panels at outwardly extending lateral edges. The arrangement and placement of cuts raises the base relative to the upright panels to provide arcuate supports for the carton.

Abstract: A pour spout for a paperboard container of either the flat top or gable top type. In one embodiment, a rectangular strip of a rigid plastics material, such as high density polyethylene, is provided with two upwardly liftable, coplanar hinged flaps, integrally formed with the strip. The flaps are aligned with respective vent and pour openings pre-cut in the container top. Upon lifting the flaps from the plane of the strip, an extruded barrier layer (typically a polymer-foil laminate) spanning the pre-cut openings is ruptured and is carried upwardly through the die-cut openings. One opening is a dispensing opening and the other a vent opening. In a second embodiment, a single integral, coplanar and also liftable flap on the rigid strip is employed to define a single pour opening. In a third embodiment, a single integral and copolanar flap on the rigid strip is covered by a flexible strip which is peeled back to expose the flap. The flap is then pushed downwardly to define a single pour opening.

Abstract: A serving container for a food product such as a hamburger. The bottom of the container is in the form of a flat plate having an upstanding rim near its periphery and is formed of paperboard. The top or crown of the container is an inverted cup formed of paperboard. The lower edge of the crown carries integral tabs which resiliently and releasably fasten into slots in an upstanding V rim of the plate. The plate serves as a base upon which the food product may be built. The crown functions to retain heat and emit moisture and may serve the additional function of a receptacle for another food product, such as french fries or salad, when the serving container is used in a so-called fast food restaurant. In food outlets serving hamburgers of different thicknesses, different height crowns alone need be stocked thus reducing container inventory.

Abstract: A wrapper for a food product such as a hamburger which is defined by an outer layer of paperboard and an inner layer of glassine type of paper. The outer and inner layers are of generally rectangular form, the glassine type of paper extending beyond the side edges of the paperboard and having top and bottom edges, a major portion of each edge having radiused cutouts. The paperboard and glassine type of paper are joined by a narrow adhesive strip running lengthwise and centrally of them. The ends of the paperboard have hinged and relatively narrow locking panels. In use, a food product such as a hamburger is placed on top of the glassine type of paper at its midlength. The wrapper is folded around the hamburger to form a tube, the wrapper ends being secured together by twisting the locking panels, with the glassine type of paper extending from both ends of the tube being bunched together and tucked in beneath the hamburger, between it and the paperboard.

Abstract: A severable wall construction for a tray forming package or carton. One or more circumferential zones is each defined by overlapping wall portions of the package or carton, each zone being Z-shaped in transverse cross-section. A tear strip (filament tape) is positioned along each zone, between the middle and one leg of the Z. The tear strip is pulled to sever the Z at the junction of the middle and one leg and thereby separate the package or carton into two portions. The remaining middle and other leg of the Z forms an edge hem for one of the two separated package or container portions. The hem edge is thus defined by a smooth rim. In one application of the invention, a paper towel roll package is provided with two Z-shaped zones around its circumference. After ripping both Z zones, that portion of the package originally between them is discarded, and two trays for display the paper towel rolls are defined. Kraft paper or paperboard forms the package or container.

Abstract: A container of generally truncated prismatic form and adapted to hold potable liquids and other foodstuffs. The container is fashioned from a single piece of paperboard coated with a layer of polyethylene on at least one surface and preferably both surfaces. The container is tapered and is closed at its bottom. Prior to filling and subsequent use of the container, the containers may be nested, whereby a single container may be iteratively removed from the nested stack for use. The container is provided with a top sealing, denesting flap which is tacked at spaced portions therealong to define a skirt having bulged segments.
