  • Patent number: 4738365
    Abstract: A container for storing a product and for holding it while it is heated in a microwave or a conventional oven. The container includes a tray-like box portion that is adherently sealed and secured inside a leakproof cover. A panel of the tray-like box has a tear-open access flap which may be tightly reclosed after being torn open and which is held in place by an interference fit between two spaced apart shoulders defined along a fold line where the access flap is joined to a reclosure tab. The panel of the tray-like box is imprinted with the instructions for heating the product enclosed within the container, while the cover is imprinted with graphics. The container is turned over during the heating process, so the instructions are visible to the consumer. Tight reclosure of the access flap tends to retain steam inside the container during the heating process thereby reducing the cooking time and retaining moisture in the product.

  • Patent number: 4657142
    Abstract: A carton is formed by rolling a sectorial piece of sheet material, preferably a lamination of at least paper and a plastic that is impervious to fluid, into the shape of a flattened cone. The lapping side edges and apex end of the cone are both sealed, whereas its base end is to be closed and sealed after placing a desired food product into the carton therethrough. The overlapping edge of the sealed side seam has a tab protruding therefrom, which tab is to be pulled for opening the carton by tearing same along a loop of tear-off strip around the cone. The cone is flattened along a pair of opposite indented lines preformed in the sheet material so as to extend between the apex end and base end of the cone. Each indented line is bifurcated at a midportion thereof into a pair of spaced apart branch lines to impart thickness to the carton.

  • Patent number: 4592914
    Abstract: A two piece container (2) for cooking food in a microwave oven including an outer package (4, 60) formed from a single blank having a removable section (8, 72, 74, 80c) for exposing water vapor ventilation holes and an inner food supporting tray (6, 48). In one embodiment, the inner food supporting tray (6) is formed from a single blank and having V-shaped support legs (44 and 46) to raise the food supporting surface (38) above the surface of the outer package. The material from which the outer package is made has a vapor absorptive characteristic. The inner food supporting tray (6, 48) is completely coated on one side with a microwave absorptive material for heating up to brown or crisp the surface of food in contact with the tray (6) and may be, in addition, coated with a stick and grease resistant material. In one embodiment of the outer package (4), a microwave reflective shielding layer is included on an inner top panel (34) to prevent overcooking of the top of food contained within the container.

  • Patent number: 4584202
    Abstract: The package allows the popping of popcorn in situ within a pouch contained in a carton. The carton has a tear-away portion in its top panel which is removed when the package is put into the microwave oven. The pouch is folded in the carton so that the edges of the folded pouch are disposed beneath the opening formed by removal of the tear-away portion. The top panel of the carton includes marginal constraining portions bounding the opening which constrain the pouch once the popcorn has commenced popping. The basal portion of the pouch is thus held in the carton while the remainder of the pouch expands through the opening during popping. The carton is provided with feet which elevate the bottom panel of the carton in the microwave oven to minimize scorching of the bottom panel during popping.

  • Patent number: 4538732
    Abstract: Tear strip structure for the relatively narrow side wall of a relatively flat rectangular paperboard carton. The side wall is defined by an inner folded closure flap and an outer flap folded thereover. The outer flap has a line of weakness extending along its length, between and parallel to its fold line and its free edge. The inner flap has a first cut score line defining its fold line and a second cut score line coincident with the line of weakness of the outer flap. The region of the outer flap overlying the region of the inner flap between the cut score lines is adherent to the latter region and defines a tear strip, an end portion of which is non-adherent and functions as a tab by which the strip may be grasped and torn away, separating the plies of the underlying closure flap between the cut score lines in achievement of removal of the tear strip in predictable, controlled manner.

  • Patent number: 4228945
    Abstract: Disclosed is a carton which is especially adapted for heating food products in microwave ovens. The bottom surface of the carton is cut to define a plurality of spaced apertures, each of which is closed by removable means. A strip of film is secured to the bottom surface of the carton and the removable means so that, upon removal of the film prior to heating, the means are removed with the film to provide vent holes which allow moisture vapor generated during heating to escape. In a preferred embodiment, the carton has two separable compartments joined by a common top and two common side walls with an intermittent cut line extending across the top and down the common side walls to permit separation of the two compartments. The compartments have individual bottom panels, each of which is cut to provide a plurality of removable tabs held within spaced apertures by spaced nicks.

    Abstract: A flexible tube container has a plurality of cells linearly disposed along the length of the tube. The cells are defined by a plurality of segmented weld lines, each segmented weld line extending the width of the tube. Each segmented weld line permits fluid communication between the various cells in the container and the formation of individual frozen confections within each of the cells upon freezing of the fluid therein. Dispensing of an individual frozen confection is easily done by bending the tube along any segmented weld line, which detaches an adjacent cell containing an individual frozen confection and immediately permits sanitary consumption of the frozen confection while it is hygienically protected within the detached cell.
