Abstract

PROBLEM TO BE SOLVED: To provide a cooler box excellent in a cold-insulating force. SOLUTION: A tabular heat insulation material 15 is continuously stuck to an outer face of an interior shell part 11 of a containing portion 1 of the cooler box. The tabular heat insulation material 15 has three tabular, open-cell foamed resin members 21 and aluminum layers 22 disposed so as to continuously cover the entire surfaces of the members 21. The members 21 are the ones that a polyurethane resin is continuously expanded and processed to a tabular shape, and are so processed as to meet each area of the interior shell part 11, which corresponds to a front side face 1a, a bottom face 1d and a rear side face 1c, respectively. Further, the aluminum layers 22 are so constituted that the coating of a synthetic resin is applied to aluminum, or that the laminate processing or the like of a synthetic resin is executed on aluminum. The aluminum layers 22 are disposed so as to cover the entire faces of the three tabular, open-cell foamed resin members 21, and connect the respective members 21 to one another.

Wherein the plate-shaped heat insulating material has three plate-shaped continuous foamed resin bodies and an aluminum layer arranged so as to continuously cover the entire surface of the three continuous foamed resin bodies. . In this case, since each continuous foamed resin body is continuously covered with the aluminum layer, and each continuous foamed resin body is connected by this aluminum layer, there is no continuous foamed resin body and only the aluminum layer is present. In parts, the plate-like insulation is bendable. Therefore, the three plate-shaped continuous foamed resin bodies are respectively disposed on the pair of side outer surface and the bottom outer surface of the inner shell portion, and these three continuous foamed resin bodies are connected without a gap, and the side outer surface and the bottom surface are formed. In addition to the outer surface portion, the cooling power can be improved without any gap near the side where the side outer surface and the bottom outer surface are in contact.

材１５は折り曲げ可能となる（図３参照）。The plate-shaped continuous foamed resin body 21 is formed by subjecting a polyurethane resin to continuous foaming and processing into a plate shape, and has a thickness of about 10 to 20 mm. The three plate-shaped continuous foamed resin bodies 21 are processed according to the area of the inner shell 11 corresponding to the front side surface 1a, the bottom surface 1b, and the back side surface 1c. The aluminum layer 22 is formed by coating or laminating aluminum with a synthetic resin. The three plate-shaped continuous foamed resin bodies 21 are disposed so as to cover the entire surface of the three plate-shaped continuous foamed resin bodies 21.
They are connected to each other. Then, the plate-shaped continuous foamed resin body 21
A portion 15a where only the aluminum layer 22 exists exists in the side portions connecting the two. Then, in the portion 15a where only the aluminum layer 22 exists, the plate-shaped heat insulating material 15 can be bent (see FIG. 3).
