使用する断熱箱体に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heat insulating box for use in refrigerators, freezers, showcases, hot storages and the like.
従来例の構成とその問題点

ックと発泡断熱材とを介在させることが提案されて来た
。Conventional structure and its problems In recent years, in order to improve the insulation performance of the insulation box and reduce the wall thickness, pressure reduction is created between the outer box and the inner box, and an insulation pack and foam insulation material are used. It has been proposed to do so.
以下この従来の断熱箱体について第３図を参考に説明す
る。This conventional heat insulating box will be explained below with reference to FIG.

口の間にたまシ発泡を開始する。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 foam insulation material is provided in the space 4 formed by the inner box 1 and the outer box 2 at the bottom 5 of the outer box 2 from the injection port 6 to the back surface 7.
Dispense foam insulation along the line. That is, this foam insulation filling method is generally called an open side-up method. Further, the outer box and the inner box are covered with a jig. However, when the insulation pack 8 is fixed to the back side with an adhesive or the like at a certain distance from the injection port, the initial flow of the foamed insulation material discharged from the injection port 6 is caused by the insulation pack 8. Foaming begins between the Gosho heating element pack 8 and the injection port.
このため、背面７全面に発泡断熱材の初流が均一に分散
されず密度の不均一や、極端な場合には断熱箱体３の天
面部９には充填しないという問題点があった。For this reason, there is a problem that the initial flow of foamed heat insulating material is not uniformly distributed over the entire back surface 7, resulting in non-uniform density, and in extreme cases, the top surface 9 of the heat insulating box 3 is not filled.
発明の目的
本発明は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ことである。OBJECTS OF THE INVENTION The present invention is to uniformly fill a conventional foam insulation material into a space formed by an outer box and an inner box.
発明の構成
本発明は上記目的を達成するため、発泡断熱材の吐出液
が背面全体にいきわたるよう形状を配慮し、断熱体パッ
クの影響をなくそうとするものである。Structure of the Invention In order to achieve the above object, the present invention attempts to eliminate the influence of the heat insulating pack by considering the shape of the foamed heat insulating material so that the discharged liquid spreads over the entire back surface.
実施例の説明
以下に本発明の一実施例を第１図、第２図を参考に説明
するが、従来と同一構成については同じ番号を符して、
その詳細々説明を省略する。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.
The detailed explanation will be omitted.

注入口６に相対するようにしている。10 is a heat insulator pack, and a surface 11 facing the injection port 6
Then, the opposite upper surface 12 attached to the back surface 7 is cut diagonally to create a new slope 13, so that this slope faces the injection port 6.
次にその作用について説明する。Next, its effect will be explained.
注入口６から吐出された発泡断熱材の初流は、相対する

ある。The initial flow of foamed heat insulating material discharged from the injection port 6 collides with the facing surface 11 and slope 13. After that, the initial flow was on slope 13.
It flows along the upper surface of the heat insulator pack 10, reaches below the top 9 of the heat insulating box 3, and foams to fill the space 4. Therefore, the foamed heat insulating material can be uniformly filled between both boxes.

る。Effects of the Invention As is clear from the above embodiments, the shape of the r/i insulation pack of the present invention is made into a single-sided shape so as not to limit the flow of the initial flow of the foam insulation material. The airflow is pervasive and the entire space is filled with foam insulation.
