して閉塞す形成するものである。 Conventionally, this type of insulating box body has an inner box and an outer box forming an insulating space, and a circular injection port for a foam insulation material such as foamed urethane is provided at a predetermined position on the back of the outer box, and the injection port is filled with foam insulation. A thin plate with elasticity that closes after injection of the material is attached, and the foamed insulation material is injected from the injection port by pressing the thin plate of the injection port with an injection cylinder, and then the foamed insulation material is foamed from the injection port. The leak is sealed by pressing the box plate against the edge of the injection port using foaming pressure from inside.
上記のようにして断熱箱体を形成するものであ
れば、外箱は大きいために該外箱の背面の所定位
置に注入口を設けるのに、大きな金型やプレス機
が必要になり、また注入口を閉塞する箱板を取着
(貼付)するのにも外箱が大きいために能率が悪
く総合的に見てコストが高くつくという欠点があ
つた。 If the insulating box is formed as described above, the outer box is large, and a large mold or press is required to provide the injection port at a predetermined position on the back of the outer box. Since the outer box is large, attaching (pasting) the box board that closes the injection port has the disadvantage of inefficiency and overall high cost.
本考案は上記のような欠点を除去した断熱箱体
に関するものである。 The present invention relates to a heat insulating box that eliminates the above-mentioned drawbacks.
以下本考案の断熱箱体の一実施例を背面に放熱
用ダクトを有する断熱箱体に実施した場合につい
て図面とともに説明する。 Hereinafter, a case where an embodiment of the heat insulating box of the present invention is implemented as a heat insulating box having a heat dissipation duct on the back side will be described with reference to the drawings.

し、その後注入口8よりの発泡断熱材7の発泡洩
れを内側からの発泡圧で薄板9を該注入口8縁に
押圧して閉塞し形成するものである。 The heat insulating box of the present invention has an inner box 1 made of plastic or the like, and a back plate 2 made of a paper sheet or the like to form only the back side, and the other side plates 3 are made of iron plates or the like. A heat insulating space 6 is formed by an outer box 5 formed by fixing a support angle 4 having an L-shaped cross section to the rear inner surface, and an inlet of a foam heat insulating board 7 is positioned at a predetermined position on the back plate 2 of the outer box 5. 8 and a box plate 9 having elasticity that closes the injection port 8 after injection of the foamed heat insulating material 7. An injection port plate 10 is attached so as to bridge the support angle 4, and 2 and press it with a jig so that it comes into contact with the horizontal surface of the angle 4, and
The back plate 2 where the injection port 8 of No. 0 is located is broken with an injection cylinder of the foam insulation material 7, and the thin plate 9 of the injection port 8 is pressed with the injection cylinder to inject the foam insulation material 7 into the insulation space 6. Thereafter, foam leakage of the foamed heat insulating material 7 from the injection port 8 is closed by pressing a thin plate 9 against the edge of the injection port 8 using foaming pressure from the inside.
上記の場合、注入口板10は外箱5とは個別に

裏板2部分の発泡断熱材が幅方向に収縮するのを
防止することができる。 In the above case, the inlet plate 10 is constructed separately from the outer box 5, and a large mold or press machine is not required to manufacture the inlet plate 10, which facilitates manufacturing. If the width of the back of the body is the same, it can be used in common, and it also works to prevent the sheet-like back plate 2 from dripping, and also prevents the foam insulation material on the back plate 2 from shrinking in the width direction. can do.

安くすることができる。 The present invention provides an insulating box body made by injecting a foamed heat insulating material into a space surrounded by an inner box and an outer box, in which the back surface of the outer box is formed with a single sheet-like backing plate, and this sheet An inlet plate having an inlet is installed between both side plates of the outer box along the inner surface of the shaped back plate, and a thin plate that is closed after injection of the foam insulation material is arranged on the inner side of the inlet plate. Since it is formed by injecting the foamed heat insulating material into the heat insulating space through the injection port through the back plate, it is easy to install and align the back plate, and the number of parts is small, making it possible to reduce costs. .
