Claims

[Scope of Claim for Utility Model Registration] 1. Vacuum insulation material 4 is placed and combined in the void created by combining the outer box 1 and inner box 2, and urethane foam 7 is placed between the two boxes using an in-situ foaming method. In the insulating box body which is filled with air, a gas vent hole 3 for injecting and foaming the urethane foam 7 into the gap between the vacuum insulating material 4 and the inner box 2 is provided at the bottom of the back of the inner box 2. A vacuum insulation material arrangement structure characterized by having a structure in which gas, etc. in the gap is discharged from the gas vent hole 3 through the hole. 2 In order to arrange the vacuum heat insulating material 4, the inner box 2 is placed near the lower back of the inner box 2, which is the final filling part of the urethane foam.
Claims for Utility Model Registration include a structure in which a plurality of gas vent holes 3 are provided in the longitudinal direction, a breathable flexible heat insulating material 5 is provided on the heat insulating material side of the hole, and then a urethane foam stock solution is injected and foamed. Vacuum insulation material arrangement as described in Item 1.
