【考案の詳細な説明】
本考案は冷蔵庫等の断熱箱体として使用され、
かつ表面にアルミ薄をラミネートしたボール紙等
を外箱の一部として使用した断熱箱体の改良に関
するもので、安価に製造できるようにすることを
目的の一つとするものである。[Detailed description of the invention] This invention is used as an insulating box for refrigerators, etc.
This invention also relates to the improvement of a heat-insulating box body that uses cardboard or the like with a thin aluminum layer laminated on the surface as part of the outer box, and one of its purposes is to enable it to be manufactured at a low cost.
従来、この種の断熱箱体は第3図に示すように
金属製の側板aにフランジbを形成し、アルミ薄

させる欠点を有していた。 Conventionally, this type of insulating box has a flange b formed on a metal side plate a, and a cardboard d laminated with a thin aluminum layer c attached to the flange b, as shown in Fig. 3.
The foamed heat insulating material g was filled between the inner box e and the outer box f. However, in such a conventional insulation box, the cut end surface h of the cardboard d is exposed to the outside air, so moisture in the outside air enters the cardboard d through the cut end surface h, degrading the insulation performance. It had drawbacks.
本考案は切断端面を断熱材側に入れることによ
り、端面のシール性の向上をはかり、断熱性の劣
化を防止するものである。 The present invention aims to improve the sealing performance of the end face by placing the cut end face on the heat insulating material side, thereby preventing deterioration of the heat insulating property.
以下、本考案をその一実施例を示す添付図面を
参考に説明する。 Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

時におけるシール性の向上をはかつている。 In the figure, 1 is the refrigerator body, and there is a door 2 on the front.
is provided so that it can be opened and closed freely. 3 is an outer box, which includes a top plate 4 made of iron plates, a side plate 5, a bottom plate 6, and a back plate 9 made of cardboard 8 with a thin aluminum layer 7 laminated on the surface.
It is composed of Reference numeral 10 indicates an inner box made of a synthetic resin material, and reference numeral 11 indicates a heat insulating material filled and foamed between the inner box 10 and the outer box 3. Here, an inwardly bent flange 12 for attaching a back plate 9 is formed on the top plate 4 and side plate 5. Further, a folded portion 13 is formed on the peripheral edge of the back plate 9 so that the cut end surface 14 is exposed to the heat insulating material 11 side. The folded portion 13 is bent in advance into an acute angle as shown by the two-dot chain line in FIG.
It has cushioning properties to ensure close contact, and improves sealing properties during foaming.

の利点を有するものである。 In the above configuration, the cut end surface 14 is exposed to the foam insulation material 11 side and is coated with the adhesive force of the insulation material 11, so moisture absorption from the cut end surface of the cardboard as in the conventional case can be prevented, and furthermore, the cut end surface 14 can be prevented from absorbing moisture from the cut end surface of the cardboard as in the conventional case. It has various advantages, such as no need for moisture proofing using the like, ease of manufacture, and cost reduction.

効果が期待できる。 Furthermore, in the above embodiment, the back plate 9 is constructed by laminating thin aluminum 7 on cardboard 8, but instead of cardboard 8, hardboard is used, and instead of thin aluminum 7, a sheet of synthetic resin such as vinyl or polyethylene is used. It may be laminated, and although it was used as a back plate, the same effect can be expected even if it is used as a top plate etc.

するものである。 As is clear from the above embodiments, the insulating box body of the present invention includes an outer box, an inner box, and a heat insulating material filled between the two boxes, and a part of the outer box is made of thin aluminum sheet and synthetic resin sheet. The plate is made of a plate such as cardboard or hardboard with a laminated surface such as cardboard or hardboard, and the plate side is placed on the foamed heat insulating material side, and the peripheral edge of the plate is folded together with a laminated aluminum thin sheet, synthetic resin sheet, etc. The cut end surface is exposed to the foam insulation material side, and when the entire outer box is made into a complex shape, the laminated plate can be used in the appropriate part, so instead of using a conventional steel plate. There is no need for large-scale equipment or complicated work processes such as bending the entire part or welding parts, and it is also lightweight. Furthermore, since the plate side is located on the foam insulation material side, the connection between the outer box and the laminated plate body can be made by the adhesive force of the foam insulation material, and this work can be omitted. Furthermore, in this connection part, the insulation performance does not deteriorate due to moisture absorption from the cut end surface of the plate, and there is no need to separately seal the end surface to prevent moisture absorption, resulting in a simple and inexpensive structure. It has various advantages such as being easy to manufacture.
