クと発泡断熱材とを介在させることが提案されて来た。BACKGROUND OF THE INVENTION In recent years, it has been proposed to interpose a depressurized insulation pack and a foam insulation material between the outer box and the inner box in order to improve the insulation performance of the insulation box and reduce the wall thickness. It's here.
以下この従来の断熱箱体について第３図を参照しながら

いる。Reference numeral 1 denotes an inner box which is assembled into an outer box 2 and forms the entire outer cover of the heat insulating box body 3. A space 4 formed by the inner box 1 and outer box 2 is filled with foamed heat insulating material (not shown) through an injection port 6 provided on the bottom surface 2a of the outer box 2. That is, the method of filling the foam heat insulating material with the back surface 5 facing upward as shown in FIG. 3 is generally called the open side bottom method. Note that the outer box 2 and the inner box 3 are covered by a jig (not shown). Further, 7 is a heat insulator pack, and a flat part 8 is attached to the inner box 1 side of the back surface 5 of the outer box 2 with an adhesive 9.
発明が解決しようとする問題点
しかしながら上記のような構成では、注入口６かも吐出
された発泡断熱材は上方に向って発泡を開始する。この

な場合には断熱箱体３の背面左右隅部１ｏには充填され
ずへこみが生ずるという問題点を有していた。Problems to be Solved by the Invention However, in the above configuration, the foamed heat insulating material discharged from the injection port 6 starts foaming upward. For this reason, since the heat insulator pack 7 is attached to the back surface 5, it is not possible to provide air vent holes in the back surface 6, and the foamed heat insulating material is not evenly distributed over the entire surface of the back surface 6, resulting in uneven density and extreme In this case, the left and right corners 1o of the back surface of the heat insulating box 3 are not filled, resulting in a dent.
本発明は上記問題点に鑑み、従来の発泡断熱材を外箱と
内箱により形成される空間内に均一に充填させる断熱箱
体を提供するものである。In view of the above problems, the present invention provides a heat insulating box body in which a conventional foam heat insulating material is uniformly filled into a space formed by an outer box and an inner box.

を区画している。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Structures that are the same as those of the conventional example are denoted by the same numbers and detailed explanation thereof will be omitted. 〇11 is a heat insulator bank. This is the width of the entire surface of the back surface 5, and has a constricted portion 12 over the entire length, and is bent at that portion due to its own weight. In addition, the inner surface 13 of the insulation pack 11 is pasted to the inner box 1 side of the back surface 5 of the outer box 2 with adhesive 9, and an air vent hole 15 is provided in the back surface 6 facing the outer surface 14. In other words, the constricted portion 12 is used as a boundary to separate the air vent hole from the other portion.
次にその作用を説明する。Next, its effect will be explained.
注入口６から吐出された発泡断熱材はボトム面１６から
上方に向って発泡する。このとき断熱体パック１１はく

クが平面となり、前記両隅部１ｏが無くなり、発泡断熱
材がすみずみに行きわたる。The foamed heat insulating material discharged from the injection port 6 foams upward from the bottom surface 16. At this time, since the insulation pack 11 is bent at the constriction 12, the holes 15 are not vented, and the foamed insulation material easily foams to the position of the insulation pack 11, and further pushes up both outer surfaces 14. As a result, the heat insulating pack becomes flat, the two corners 1o are eliminated, and the foamed heat insulating material is spread throughout.
以上のように本実施によれば、断熱体パックの屈曲した
外の面に対向した背、面に穴を設けることにより、発泡
断熱材を両箱間に均一に充填できる。As described above, according to this embodiment, by providing holes in the back and the surface opposite to the bent outer surface of the heat insulator pack, the foamed heat insulating material can be uniformly filled between both boxes.

くなる。Effects of the Invention As described above, the present invention has a constricted portion along the entire length of the heat insulator pack, the surface facing the air vent hole on the back of the outer box is the free end, and the other surface is attached to the back with adhesive. Finally, the entire inner box and outer box spaces are filled with foamed heat insulating material, so that the foam density is uniform and there are no dents on the left and right corners of the back.
