  • Patent number: 9868581
    Abstract: Microwave cooking packages suitable for use as microwave popcorn packages include at least one panel (e.g., first and second panels) formed of a vertically rigid material. A flexible portion is attached to the panels. The flexible portion may be formed of a polyester film material such as a biaxially-oriented polyethylene terephthalate (PET) film, which may be at least partially transparent. The flexible portion (and panels) defines a bag construction configured to contain a popcorn charge and to be expandable between a collapsed configuration and an expanded configuration when the popcorn charge is subjected to a popping operation. The microwave cooking package may include a vent assembly configured to at least partially open when the bag configuration is in an expanded configuration to vent the bag construction. The vent assembly includes a first portion a second portion of the bag construction that is configured to be folded against the first portion.

  • Patent number: 9199781
    Abstract: A flexible packaging laminate for a microwavable package has a built-in vent for steam. The vent is formed by an outer score line through the outer layer(s) of the laminate to define an outer flap, and a smaller-footprint inner score line formed through the inner layer(s) of the laminate, so that there is a marginal region of U- or V-shape bounded between the two score lines. A patch of pressure-sensitive adhesive is disposed between the outer and inner structures of the laminate such that PSA is present in the marginal region. Pressure exerted on the inner flap or plug created by the inner score line overcomes the PSA between the outer flap and the inner structure in the marginal region, causing the outer flap to be pushed out along with the inner flap or plug, thereby venting steam through the resulting opening.

  • Patent number: 7855351
    Abstract: A system for preparing, cooking, and treating expandable products in a microwave oven. Under pressure of the microwaves, pressure of one or more components acts to break one or more seals between the cells so that the components can mix and provide a desirable end product, which can be a liquid or solid form. The disposable system can make hot beverages and meals and create other products. Creating or decreasing pressure on the components causes expansion of a plastic or other material located between the non-shrinkable member and the shrinkable member. Expansion of the components under microwaves acts to aid the forcing of liquid through the divider.

  • Patent number: 7241980
    Abstract: A control method for a microwave oven equipped with a tray installed in a cooking chamber to rotate a popcorn bag while having a popcorn cooking mode to cook popcorn. During cooking, rotation of the tray is temporarily stopped near the point of time when the popcorn bag is increased in size to a maximum size. Accordingly, problems caused by the fact that the popcorn bag comes into contact with the inner wall surface of the cooking chamber so that it cannot rotate are solved. The popcorn cooking mode is an operation mode to cook a popcorn product with corn grains packed in the popcorn bag in a state in which it is folded at least one time. The rotation of the tray is temporarily stopped near the point of time when the popcorn bag is estimated to achieve its maximum length as a folded portion of the popcorn bag is unfolded.

    Abstract: A menu selection device for a microwave oven is provided which is constructed such that a single display device may be divided into a menu guide unit and a menu selection unit. The menu guide unit is used to display a variety of menus, whereas the menu selection unit is constructed in the form of a touch screen which allows for selection of a particular menu from among the menus displayed on the menu guide unit. Use of a menu guide unit and a menu selection unit within a single display device makes a greater variety of cooking alternatives available to a user, while decreasing the size of the touch screen portion of the menu selection device and decreasing production costs.

  • Patent number: 7022955
    Abstract: The present invention relates to a container for the microwave heating of a food product in which a sheet of barrier material is sealed around a food product to a blank having one or more panels which can be folded to assemble a container. The sheet of barrier material forms a pocket inside which a food product may be disposed. The sheet of barrier material is sealed to one of the panels, so that a peripheral outer portion is formed to separate the food product from the remaining panel or panels. The barrier material may be moisture impervious, and may be sealed to the blank using a vacuum platen or heat-sealing methods. A microwave susceptor can be disposed on the blank, which is made from a material suitable for microwave heating such as a polymer and paperboard laminate.

  • Patent number: 6951999
    Abstract: A flexible paper microwave package in the form of an easily expandable, nontrapping bag (18) is disclosed including a bottom wall (20) and a top wall (22) interconnected together adjacent their circular outer peripheries (20a, 22a) by first and second interconnection portions (26a, 26b). In one preferred form, the top wall (22) is formed from a first portion (22d) having a generally oval shaped access opening closed by a generally oval shaped closure portion (22e) interconnected by a wet adhesive seal (40) to the first portion (22d). In a preferred form, the wet adhesive seal (40) is formed by a plurality of spaced, parallel bands (400, 401, 402) defining a plurality of spaced, parallel spaces therebetween for resisting any leakage from the interior of the bag (18) through the seal (40). The bottom and top walls (20, 22) expand into an opposing double domed shape as the food product is being popped, puffed, or expanded in the microwave oven.

  • Patent number: 6884978
    Abstract: A flexible paper popcorn package in the form of an easily expandable bag (18) includes a bottom wall (20), a top wall (22), first and second, pleated, side walls (26) having pleats (26a-26d), and first and second non-venting ends (24, 28). Spots (60, 62) of adhesive may be provided between the pleats (26a-d) and the top and bottom walls (20, 22) to prevent the formation of pockets adjacent the end (24). Couplers (70) formed of adhesive are provided between the pleats (26b, 26d) and the top wall (22) which seal apertures (72) in the pleats (26b, 26d) which vent during microwave popping, puffing, or expanding of a food product held in the bag (18) and which may predispose unfolding of the pleats (26a, 26c) adjacent the bottom wall (20) including the susceptor (30).

  • Patent number: 6828536
    Abstract: A dielectric welding apparatus for welding a plastic sleeve contains a solid state radio frequency generator linked via a matching network to a welding tool. The tool (30) includes a frame (35) with a handle (36), the frame defining a slot in which are opposed welding electrodes (40, 44), the slot being open at one end and at the other end communicating with a wider aperture (39). A pneumatic cylinder (48) can be actuated to urge the electrodes together, both the cylinder (48) and the RF generator (66) being activated by a trigger (50) on the tool (30). The electrodes are coated with an electrically insulating material that is not dielectrically heated, and are readily removable, so they can be replaced, for example when the electrically insulating coating becomes worn.

  • Publication number: 20040031790
    Abstract: A control method for a microwave oven equipped with a tray installed in a cooking chamber to rotate a popcorn bag while having a popcorn cooking mode to cook popcorn. During cooking, rotation of the tray is temporarily stopped near the point of time when the popcorn bag is increased in size to a maximum size. Accordingly, problems caused by the fact that the popcorn bag comes into contact with the inner wall surface of the cooking chamber so that it cannot rotate are solved. The popcorn cooking mode is an operation mode to cook a popcorn product with corn grains packed in the popcorn bag in a state in which it is folded at least one time. The rotation of the tray is temporarily stopped near the point of time when the popcorn bag is estimated to achieve its maximum length as a folded portion of the popcorn bag is unfolded.
