Insulated container for keeping lunch food

Abstract

An insulated food container has a container part and a detachable cover part having a handle. The cover part connectable to the container part by at least one clip on each of four sides of the container. The container part and cover part each comprising an outer shell of non-heat conducting material and an inner shell of food-grade non-heat conducting material. A vacuum gap between the outer shell and inner shell providing insulation. A silicone coating applied to an exterior face of the inner shell, the silicone coating separated from the inner shell by a perimeter hem creating a small gap between the silicone coating and inner shell. Wherein the silicone withstands hot or cold temperatures without damage, providing exceptional thermal insulation over extended time periods.

What is claimed is: 
     
         1 . An insulated food container, comprising:
 a container part and a detachable cover part having a handle;   the cover part connectable to the container part by at least one clip on each of four sides of the container;   the container part and cover part each comprising an outer shell of non-heat conducting material and an inner shell of food-grade non-heat conducting material;   a vacuum gap between the outer shell and inner shell providing insulation;   a silicone coating applied to an exterior face of the inner shell, the silicone coating separated from the inner shell by a perimeter hem creating a small gap between the silicone coating and inner shell;   wherein the silicone withstands hot or cold temperatures without damage, providing exceptional thermal insulation over extended time periods.   
     
     
         2 . The insulated food container of  claim 1 , further comprising a grid pattern of ribs providing structural integrity to the outer shells of the container part and cover part. 
     
     
         3 . The insulated food container of  claim 1 , wherein the gap is a vacuumed space between the outer shell and inner shell. 
     
     
         4 . The insulated food container of  claim 1 , wherein the container maintains a temperature above 140° F. for over 3 hours. 
     
     
         5 . The insulated food container of  claim 1 , wherein the container maintains a temperature below 40° F. for over 5 hours. 
     
     
         6 . The insulated food container of  claim 1 , wherein the outer shells are made of polypropylene. 
     
     
         7 . The insulated food container of  claim 1 , wherein the silicone withstands hot and cold temperatures without degradation over time.
