The inner sole material 24 is inserted. Here, the heat insulating inner wall material 20
The heights of 23 to 23 are lower than the height of the outer box 5 by the thickness of the heat insulating lid member 25. Then, the inner wall 6 near the opening 5a of the outer box 5 and the upper end surfaces 20d to 2 of the heat insulating inner wall members 20 to 23 are formed.
3d and side surfaces 20c to 23 of the heat insulating inner wall materials 20 to 23
The upper part of c is covered with a strip-shaped covering material 32 of the same quality as the outer box 5.
The upper end of the covering 32 is sewn along the inner circumference to the inner wall 6 near the upper opening 5a of the outer box 5. The lower end of the coating material 32 is attached to the side surface 2 of the heat insulating inner wall materials 20 to 23 with the adhesive tape 33.
It adheres to 0c-23c. An article is put into the cold-insulating box 30 manufactured in this way, the opening 5a is closed with the heat insulating lid member 25, and the cold-insulating box 30 is transported while keeping the internal temperature.

First, the four edge members 10 to 13 are fixed to the inner wall 6 of the opening 5a of the outer box 5 along the inner circumference thereof. Specifically, first, as shown in FIG. 2, the joining pieces 10b to 13b of the respective edge members 10 to 13 are inserted into the opening 5a so as to be in close contact with the inner wall 6. Edge member 10
The height at which the upper surfaces 10a to 13a are fixed is such that the positions of the upper surface portions 10a to 13a are lower than the upper end of the outer box 5 by the thickness of the heat insulating lid member 25. And the upper edge piece 10c of the edge members 10-13
13c is sewn to the outer box 5 (seam n). When sewing is performed in this manner, the upper edge pieces 10c to 13c need to be formed into a thickness that enables sewing. Further, as will be described later, when the heat insulating lid member 25 is fitted, it is necessary to have a rigidity that does not cause bending. In addition, the edge members 10 to 1
The fixing of 3 is not limited to sewing, and the edge members 10 to 13 may be fixed to the outer box 5 with an adhesive. In order to protect the upper ends of the outer case 5 and the upper edge pieces 10c to 13c, cloth for edging may be sewn so as to cover the upper ends of the both.
