Insulated Lunch Box

Abstract

An insulated lunch box comprising: (1) a double-walled, insulated base; (2) an insert; and (3) a double-walled, insulated lid. The insulated lunch box is designed to store a hot pack or cold pack in the double-walled, insulated base between the double-walled, insulated base and the insert. Some embodiments may also allow for storage of a hot pack or cold pack in the double-walled, insulated lid between the double-walled, insulated lid and the insert.

         2 . The insulated lunch box of  claim 1  wherein the insert is wrapped in a material that has lower thermal conductivity than the at least one food container. 
     
     
         3 . The insulated lunch box of  claim 1  wherein the insert comprises a material that has lower thermal conductivity than the at least one food container. 
     
     
         4 . The insulated lunch box of  claim 2  wherein the double-walled, insulated lid comprises a hot pack. 
     
     
         5 . The insulated lunch box of  claim 3  wherein the double-walled, insulated lid comprises a hot pack. 
     
     
         6 . An insulated lunch box comprising:
 a double-walled, insulated base;   a double-walled, insulated lid; and   an insert wherein the insert comprises at least one food container;   wherein the double-walled, insulated base comprises a cold pack.   
     
     
         7 . The insulated lunch box of  claim 6  wherein the insert is wrapped in a material that has lower thermal conductivity than the at least one food container. 
     
     
         8 . The insulated lunch box of  claim 6  wherein the insert comprises a material that has lower thermal conductivity than the at least one food container. 
     
     
         9 . The insulated lunch box of  claim 7  wherein the double-walled, insulated lid comprises a cold pack. 
     
     
         10 . The insulated lunch box of  claim 8  wherein the double-walled, insulated lid comprises a cold pack. 
     
     
         11 . An insulated lunch box comprising:
 a double-walled, insulated base comprising a lip to insert an insert comprising at least one food container; and   a double-walled, insulated lid.   
     
     
         12 . The insulated lunch box of  claim 11  wherein the insert is wrapped in a material that has lower thermal conductivity than the at least one food container. 
     
     
         13 . The insulated lunch box of  claim 11  wherein the insert comprises a material that has lower thermal conductivity than the at least one food container. 
     
     
         14 . The insulated lunch box of  claim 12  wherein the double-walled, insulated base further comprises a cold pack. 
     
     
         15 . The insulated lunch box of  claim 12  wherein the double-walled, insulated base further comprises a hot pack. 
     
     
         16 . The insulated lunch box of  claim 13  wherein the double-walled, insulated base further comprises a cold pack. 
     
     
         17 . The insulated lunch box of  claim 13  wherein the double-walled, insulated base further comprises a hot pack. 
     
     
         18 . The insulated lunch box of  claim 15  wherein the double-walled, insulated lid comprises a hot pack. 
     
     
         19 . The insulated lunch box of  claim 16  wherein the double-walled, insulated lid comprises a cold pack. 
     
     
         20 . The insulated lunch box of  claim 17  wherein the double-walled, insulated base further comprises a hot pack.
