Claims

[Scope of utility model registration request]

In the insulating box body, the insulating box body has an outer box formed by combining a plurality of plate materials, an inner box installed inside the outer box, and a heat insulating material filled in a space between the outer box and the inner box. A front edge flange is formed around the opening of the inner box, and at least a side plate of the plates constituting the outer box has a double flange that engages the front edge flange, and a bottom front plate and a partition plate have a double flange that engages the front edge flange. A heat insulating box body characterized in that bent portions that are engaged with the double flanges are respectively formed, and the double flanges and the bent portions are fastened by a fastening means.
