本発明は、冷蔵庫等に用いられる断熱容器に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heat insulating container used in refrigerators and the like.
従来の技術 第３図、第４図は従来の断熱容器を示している。Conventional technology FIGS. 3 and 4 show conventional heat insulating containers.

を有するものである。In the figure, reference numeral 1 denotes a flat heat insulating pack, in which a filler 2 made of open cells and a getter agent 2' such as activated carbon or zeolite are housed in a flat shape.
The container is covered with a sealed container 3 made of a metal laminate film or the like to reduce the pressure inside. 4 is a heat insulating box with an outer panel 5 and an inner panel 6
A heat insulator pack is fixed in advance to the outer panel 5 side with adhesive 7, etc. in the space formed by
It has a structure in which it is filled with a foamed heat insulating material 9 such as urethane foam.

断熱体パック１を曲げ、平滑面が出ないという問題点も
有していた。Problems to be Solved by the Invention However, when attaching the insulation pack 1 to the outer panel 6, due to manufacturing variations, if the outer panel 5 or the insulation pack 1 is not smooth enough, the normal adhesive 7 Then, a gap is created between the outer panel 5 and the insulation bag 1, and when the foam insulation material 9 is filled, the insulation material 9 enters into this gap, creating an unfilled area 1o.The insulation material 9 is inserted into this unfilled area. When R-11 accumulates and the outside air drops, the pressure in the unfilled area becomes lower than the atmospheric pressure, causing deformation of the outer panel 1.Also, hot melt adhesives are available as thick coating adhesives, but after application , the hot melt shrinks,
Another problem was that the heat insulator pack 1 was bent and a smooth surface was not exposed.
本発明は上記問題点に鑑み、断熱体パックの変形を防止
すると共に外板又は内板の変形のない断熱箱体を提供す
るものである。In view of the above problems, the present invention provides a heat insulating box that prevents deformation of the heat insulator pack and does not cause deformation of the outer or inner panels.

温度差が少く断熱体パック１を曲げることがない。Function: Since it is a foamed hot melt, a predetermined thickness can be ensured, and since it has bonding strength, it can adhere the insulation pack and the outer panel without creating a gap. Furthermore, since it is a foamed product, the temperature decreases during application, and the difference in temperature between the time of application and room temperature is small, so that the heat insulator pack 1 does not bend.

ているため、断熱性能も向上する。Next, the operation of this embodiment will be explained. The foamed hot melt adhesive 11 has a low viscosity of 4000 cps or less at 180°C, so its melting temperature is low. Therefore, the temperature of the foamed hot melt adhesive 11 during application is around 60°C, and it is insulated by shrinkage when returning to room temperature. It is applied to the surface of the heat insulator pack without bending the body pack 1 and has a thickness of about 5 to IC)+m. Therefore, if the strain is within this range, this foamed hot melt adhesive will fill it. There are no gaps left. Therefore, an unfilled portion 10 of the foamed heat insulating material 9 is not formed, and the outer panel 6 is not deformed. Furthermore, since the adhesive is foamed, the heat insulation performance is also improved.
