Thermal Insulation Box

Abstract

A thermal insulation box includes a casing and a liner. The casing includes a casing body and a casing lid. The casing lid is openably coupled to an opening of the casing body. The liner is disposed in the casing body and includes a waterproof fabric and a thermally insulating layer disposed between the waterproof fabric and an inner wall of the casing body. The waterproof fabric is made of a mesh fabric having a mesh made of polyethylene yarns and at least one film bonded to each of two sides of the mesh.

1 . A thermal insulation box comprising:
 a casing including a casing body and a casing lid, wherein the casing lid is openably coupled to an opening of the casing body; and   a liner disposed in the casing body and including a waterproof fabric and a thermally insulating layer disposed between the waterproof fabric and an inner wall of the casing body, wherein the waterproof fabric is made of a mesh fabric having a mesh made of polyethylene yarns and at least one film bonded to each of two sides of the mesh, wherein processed cross sections of the waterproof fabric are not treated by heat sealing.   
     
     
         2 . The thermal insulation box as claimed in  claim 1 , wherein the thermally insulating layer is made of polyphenylene oxide (PPO). 
     
     
         3 . The thermal insulation box as claimed in  claim 1 , wherein the mesh fabric is an ethylene-vinyl acetate (EVA) mesh fabric in which the at least one film on each of the two sides of the mesh is at least one EVA film. 
     
     
         4 . The thermal insulation box as claimed in  claim 3 , wherein the EVA mesh fabric has a working temperature in a range of −40 to 70° C. 
     
     
         5 . The thermal insulation box as claimed in  claim 1 , wherein the waterproof fabric completely covers the thermally insulating layer, and wherein the waterproof fabric has an edge coupled to the inner wall at a top end of the casing body. 
     
     
         6 . The thermal insulation box as claimed in  claim 5 , wherein the liner includes another thermally insulating layer disposed between another waterproof fabric and an inner wall of the casing lid, wherein the another waterproof fabric completely covers the another thermally insulating layer, wherein the another waterproof fabric has an edge coupled to the inner wall of the casing lid, wherein when the casing lid is in a closed state covering the opening of the casing body, the another thermally insulating layer at the casing lid is located above the thermally insulating layer at the casing body, and wherein the another waterproof fabric at the casing lid abuts the waterproof fabric at the casing body. 
     
     
         7 . The thermal insulation box as claimed in  claim 1 , wherein the liner includes at least one reflective layer disposed between the thermally insulating layer and the inner wall of the casing body. 
     
     
         8 . The thermal insulation box as claimed in  claim 1 , further comprising a supporting board disposed between the liner and the casing body, wherein the supporting board is a plastic, hollow, corrugated board. 
     
     
         9 . The thermal insulation box as claimed in  claim 1 , wherein the casing body and the casing lid are partially connected to each other, and wherein when the casing lid is in a closed state, the casing body and the casing lid are maintained in a connected state by a waterproof zipper unit. 
     
     
         10 . (canceled) 
     
     
         11 . The thermal insulation box as claimed in  claim 1 , wherein the casing lid is disposed on a top end of the casing body, and wherein an annular wall is disposed around a peripheral edge of a top side of the casing lid.
