Abstract:
1. An insulated food container for warming food and keeping food warm and moist comprising: a bag-like water impermeable pouch defining an internal food-receiving chamber and further defining a food passage opening in communication with the food-receiving chamber, the pouch being closed around a peripheral edge extending from one side of the food passage opening to an opposed side of the food passage opening; an upper insulating structure including first upper and lower cloth-like layers with a first layer of insulating material sandwiched therebetween, the first upper and lower cloth-like layers defining a first outer edge, and the first upper and lower cloth-like layers being joined and reinforced in a first continuous bead extending completely around the first outer edge; a lower insulating structure including second upper and lower cloth-like layers with a second layer of insulating material sandwiched therebetween, the second upper and lower cloth-like layers defining a second outer edge, and the second upper and lower cloth-like layers being joined and reinforced in a second continuous bead extending completely around the second outer edge; the upper insulating structure and the lower insulating structure being positioned in overlying relationship with the pouch sandwiched therebetween, the first outer edge and the second outer edge of the upper insulating structure and the lower insulating structure, respectively, being joined together adjacent the edge of the pouch and coextensive with the closed peripheral edge of the pouch from one side of the food passage opening to the opposed side of the food passage opening without obstructing the food passage opening; and the first continuous bead and the second continuous bead forming upper and lower lips positioned in passive, non-sealing engagement with each other for the extent of the food passage opening to inhibit a build-up of moisture vapor produced from warm food disposed in the food-receiving chamber for preventing warm food disposed in the food-receiving chamber from becoming soggy and to allow enough moisture vapor to remain in the food-receiving chamber for keeping warm food disposed in the food-receiving chamber moist.
