  • Publication number: 20080248173
    Abstract: A device to improve microwave cooking is described. The device (10) comprises a plurality of containers (12, 22) that include a venting mechanism (15, 25) on each container (12, 22). On of the containers (12) defines a first volume (14) for holding food. Another container (22) defines a second volume (24) and is operatively coupled to the first container (12). During microwaving of the food, steam is released into the first volume (14) defined by one of the containers (12). Pressure builds up creating a first pressure treatment for the food until the venting mechanism (15) is activated. Steam exits the first volume (14) through the venting mechanism (15) and enters the second volume (24). Again, pressure builds up to create a second pressure treatment for the food until the venting mechanism (25) for the container (22) is activated.

  • Publication number: 20080203092
    Abstract: An easily closable and openable container system includes a number of features which facilitate easy opening and closing while maintaining a high seal. In a first embodiment, the opening forces can be concentrated on one narrow side which includes a lip on one side of a lid flange and with an angled portion on the opposite side of the flange to give ease of opening with less force involved. In a second embodiment where one side is not significantly shorter than a longest side, the lid flange is located at a corner to concentrate the leverage for opening. A continuous flange surrounds a generally planar member and mates with a outwardly projecting rim. The flange includes a pair of surfaces, including an inwardly angled surface which acts to form a stable seal, and actually urges the lid downward as the natural sealing force from the flange is applied.

  • Publication number: 20080175966
    Abstract: A high pressure food package and system including a cup for holding a quantity of food product, a lid for covering the cup, and at least one one-way sealing mechanism that permits a gas to pass through the sealing mechanism into the interior space enclosed by the cup and lid and that prevents the gas from escaping from the interior space through the sealing mechanism. The high pressure package (and system and method for using the same) is especially well suited for producing a food product (such as fruits or vegetables) having an effervescent sensory (or carbonated) character.

  • Patent number: 7074443
    Abstract: Packaging for a can containing ground roasted coffee packed under atmospheric pressure and having a flexible peel-off lid which is vented to allow the escape of a buildup of carbon dioxide gases. A spacing structure prevents the vent valve in the lid from being closed by contact with the plastic overcap. The spacing structure may include bosses on the overcap which engage the vent valve or a pocket in the overcap which allows the flexible lid to reach a maximum height without engaging the overcap. A permanently opened passageway may be provided between the plastic overcap and the rim of the can to further facilitate the escape of carbon dioxide.

  • Patent number: 7045190
    Abstract: A packaging material is provided that can provide a packaging bag or container cover in which the contents is shielded from the atmosphere and tightly sealed, a small hole is formed in the appropriate locations, without special processing of the heat seal portion, and the internal pressure is maintained with high stability at a level above the normal pressure. The packaging material is suitable, for example, for heating in a microwave oven. The packaging material uses a film in which a heat sealing agent (4) with a low melting point is applied to a prescribed zone of an oriented film (2) made of a synthetic resin, a cutting line (5) is cut in the oriented film (2) made of a synthetic resin in the form of a solid or broken line passing through the zone coated with the heat sealing agent (4), and a cast film (3) made of a synthetic resin and having heat sealing properties is affixed to the oriented film (2) made of a synthetic resin. Such film is used for a packaging bag (1) or a container cover.

  • Publication number: 20020088812
    Abstract: A container with side and end walls, a top and a bottom, has a closure with a panel movable outwardly perpendicular to a plane of the closure, from a closed and substantially sealed position to a closed and substantially unsealed position to disengage the seal before undertaking a more gross opening movement in which the panel is moved clear of the opening. In one embodiment, a container is provided with a rear or end wall that in its gross movement hinges open and closed to clear or close an opening between container side walls. At least two hinges are mounted between the movable rear wall and a support plate on a sidewall adjacent to the movable rear wall. The support plate is constrained to move perpendicular to the plane of the door opening, shifting the rear wall between a closed and substantially sealed position and a closed and substantially unsealed position.

  • Patent number: 6349842
    Abstract: The present invention relates to a rotatable cover which can be screwed or plugged on and is to be fastened on a stationary connection of a motor vehicle radiator or compensator reservoir of cooling and heating systems. The cover has a screw or plug cap and/or swivel cap and a rotatable engagement part in which a valve in the form of a combined overpressure/underpressure unit is arranged concentrically. The valve has a sealing member which produces a sealing connection with the stationary connection when the cover is applied. When the cover is positioned on the stationary connection, it is possible to prevent by means of a temperature-related control member removal, such as unscrewing or twisting of the cover. The temperature-related control member or a coupling part actuated by means of the temperature-related control member can be moved substantially radially between a coupling position and a release position.
