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.
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.
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.
