Abstract: A paperboard cup holder for use with a hot coffee cup, the cup being tapered as in the form of a cross section of a right circular cone of relatively small taper angle. Such cups are generally of paperboard or plastic and are often used in vending machines and fast food retail outlets for serving hot coffee. The holder is formed from a flat, generally arcuate unitary paperboard blank having a convex outer edge and a concave inner edge. The arcuate length of the blank is substantially the same as the mid circumference of the cup, and the ends of the blank are glued together to form an annular holder. The upper edge of the blank integrally carries a plurality of apertured flaps which bend 180 degrees to as to lie parallel with the main portion of the blank. When the holder is slid onto a cup, the apertured flaps are sandwiched between the outer (hot) surface of the cup and the main portion of the holder.

Abstract: An identification button construction for a paperboard clamshell carton or container. An edge of the carton lid, such as a horizontal edge, is provided with a plurality of cuts or scores which form the periphery of individual identification buttons. Such buttons are used to indicate the presence or absence of an ingredient or garnish for a hot food item such as a hamburger sandwich. The peripheral scores or lines of the button are cut about half way through the paperboard from the outer carton surface towards the carton interior. An elongated Z shaped cut, completely through the paperboard, bisects the button, at a right angle to the crown edge. The crown edge also bisects the button. While a diamond shape button is illustrated, round, oval, or other polygonal shapes may be employed.

Abstract: A clamshell type paperboard container formed from a unitary blank of paperboard. Two embodiments are described. In the first, the container is square and the lid includes four triangular panels meeting at an elevated and central common point. In the second, the container in rectangular and the lid includes two triangular panels and two trapezoidal panels, and the central elevated portion of the lid includes an elongated ridge or rib. These constructions prevent stacking and hence inadvertent crushing of a closed and filled container. The slanting sides of the lids yield an easel effect for graphics thereon.

Abstract: A container formed of two identical trays. Each tray carries two flanges, the flanges extending from opposite side walls of a tray. One surface of each flange is provided with a layer or coating of a cohesive material. Such a material adheres only to other cohesive surfaces. Storage of the coated blanks, and of the erected trays, is hence facilitated. The container is particularly useful for the packaging of fast food items.

Abstract: A french fry scoop formed from a unitary blank of paperboard is provided with generally horizontally extending lower legs. The legs extend tangentially from the lower edges of the scoop and permit the filled scoop to be placed on a horizontal surface in slightly tilted, stable equilibrium. The scoop displays both economy in paperboard required and a pleasing rest position from which the consumer can withdraw product.

Abstract: An indicia tab construction for a paperboard food wrapper or container. In one embodiment a peripheral indicia tab is foldable about a lateral axis to assume one of two configurations, and is held in a folded configuration by a cohesive layer. In a second embodiment each of a plurality of peripheral indicia tabs is foldable about respective aligned axes and is also held in folded configurations by respective cohesive layers. In a third embodiment one or more foldable indicia tabs are attached to the periphery of one half of a foldable food wrapper, each tab provided with a legend or other indicia normally viewable. These tabs may be, selectively, folded so as to uncover other legends or indicia, normally covered, on the other wrapper half.

Abstract: A carton for a package of photographic film, such as instant film. The carton is formed of a unitary paperboard blank coated on both sides by a thermoplastic barrier film. The thermoplastic functions as an adhesive when acted upon by heat and pressure, thus sealing portions of the blank together. Each of four corners of the carton includes a gusset folded in such a manner as not to present a raw paperboard edge to the interior. The construction yields an air tight, liquid tight package with an oxygen barrier, and obviates the requirement of many similar packages that the photographic film be separately wrapped in a protective foil or film prior to being placed in a carton. Three embodiments of the carton are disclosed.

Abstract: A carton formed from a unitary blank of paperboard, the carton exhibiting particular utility as a wrapper or container for food products, such as sandwiches. A sandwich may be formed on the wrapper before folding and forming the wrapper into a carton. Or the sandwich may be made and then placed on the wrapper blank, with two opposite ends of the blank then pulled upwardly around the sandwich. Each end is coated with a layer of cohesive material on one surface, these two surfaces being adhered together to form an upper rib of two thicknesses of paperboard, the end walls of the container then being easily manually formed. The cohesive material has the property of sticking only to itself and the coated ends are readily separated and readily reclosed.

Abstract: A clamshell type container is formed from a unitary blank of paperboard. The central portion of the crown of the carton is convex upwardly and the crown carries inwardly concave opposite side walls. The four corners of the crown are each provided with triangular gussets to permit slight deformation of the crown both upon stacking of the open cartons and upon closing the crown down onto the lower tray part of the carton. The tray side walls are curved or recessed downwardly so as to form line contact with a respective crown side wall, such contact defining a seal and inhibiting warm air loss when a warm foodstuff is placed in the carton.

Abstract: A carton carrier fashioned from a unitary blank of paperboard displays utility in carrying two or more cartons of the cable top type. The carrier is in the general form of an inverted rectangular tray, with the longitudinal side walls of the tray having double thickness tongues which fit into end recesses of respective gable top cartons, such as milk cartons. The carrier may be carried by placing fingers inside an opening on its top surface. The construction permits vertical stacking of groups of gable top cartons and also provides sufficient strength for carrying the cartons.

Abstract: A package particularly useful for either conventional oven or microwave heating of refrigerated or frozen foodstuffs includes a lower paperboard tray, an upper frangible paperboard cover, and an intermediate compartmentalized plastic food tray. The bottom of the plastic tray food compartments rest on the tray bottom. The plastic tray side edges are clamped between laterally extending side flanges on the lower tray and edges of the top cover. The top cover is removed by ripping along tear lines. After consumption of the food, the plastic tray is readily removed to thereby facilitate separation for recycling. The package construction also facilitates the use of relatively thin plastic for forming the compartmentalized plastic tray because the weight of the foodstuffs in the plastic tray components is partially borne by the lower tray.
