Food Crisper via Condensation Trap Cup

Abstract

A “condensation cup” for inducing condensation on the cup's surface in order to keep hot food dry and crispy. By filling the condensation cup with cold liquid and positioning it inside a closed container with hot food, the condensation cup will induce condensation from the ambient air inside the container. This invention focuses on controlling the aggregate uninsulated surface area of cup. By matching the aggregate uninsulated surface area of the cup with the amount of contained hot food, the preferred condensation cup can pull condensate from the air. This induced condensation keeps hot food dry and crispy without cooling the food.

What is claimed is: 
     
         1 . A cup for keeping food dry, the cup comprising,
 a double wall connected to a base, the wall and base enclosing an inside chamber for holding liquid, the double wall comprising an inner wall, an outer wall and a space between the inner and outer walls,   a perforation through the outer wall that exposes an outside face of the inner wall to ambient air, and   a barrier positioned along a perimeter of the perforation to keep ambient air from entering into the space.   
     
     
         2 . A cup for keeping food dry, the cup comprising,
 a single wall connected to a base, the single wall and base enclosing an inside chamber for holding liquid,   an insulating layer connected to an outside face of the single wall, the insulating layer only partially covering the outside face,   wherein an aggregate surface area of uninsulated single wall is of a size predetermined to induce condensation without cooling the food.   
     
     
         3 . The cup of  claim 2 , the insulating layer is an insulating sleeve connected to the outside face via a friction. 
     
     
         4 . A food transportation device, the food transportation device comprising
 a container containing hot food,   a cup inside the container containing cold liquid, the cup comprising an insulated section and an uninsulated section, the uninsulated section sized to induce condensation without cooling the hot food.   
     
     
         5 . A method of transporting food, the method comprising the steps of,
 placing food in a container, the food comprising a first temperature,   placing a cup comprising liquid in the container, the liquid comprising a second temperature, the second temperature lower than the first temperature, the cup comprising an insulated section and an uninsulated section, the uninsulated section sized to induce condensation without cooling the hot food, and   closing the container for transportation.   
     
     
         6 . A method of storing food, the method comprising the steps of,
 placing food in a container, the food comprising a first temperature,   placing a cup comprising liquid in the container, the liquid comprising a second temperature, the second temperature lower than the first temperature, the cup comprising an insulated section and an uninsulated section, the uninsulated section sized to induce condensation without cooling the hot food, and   closing the container for storage.
