<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing device for a thermal insulation box, for smoothly and favorably injecting foam heat insulation material even in the case of fitting a vacuum heat insulation material to the inner surface of an outer case. <P>SOLUTION: A thermal insulation box 6 includes: the outer case 2, an inner case 3, and the vacuum heat insulation material 73 fitted to the surface on the inner case 3 side of the outer case 2. This manufacturing device for the thermal insulation box is provided for injecting foam heat insulation material between both cases 2, 3 by foaming in place. An air vent hole 77 for injecting the foam heat insulation material is formed in the inner case 3, and a foaming inner tool abutting on the inner case in injecting the foam heat insulation material is provided with an air vent passage 81 disposed in a position corresponding to the air vent hole 77 to communicate with the air vent hole 77. <P>COPYRIGHT: (C)2004,JPO</p> |
