断熱材９を充填した構成を有するものである。In the figure, reference numeral 1 denotes a flat heat insulating pack, which houses a flat filler 2 made of foam such as open cell foam, and is covered with a sealed container 3 made of a plastic-metal laminate film or the like. The interior is depressurized. Reference numeral 4 denotes a heat insulating box body, and in the space formed by the outer panel 6 and the inner panel 6, a heat insulating pack is fixed in advance to the outer panel ε side with an adhesive 7, etc., and filling ports 8, 8' are made in the outer panel 6. It has a structure in which a foamed heat insulating material 9 such as urethane foam is filled.

発明が解決しようとする問題点
外板６に断熱体パック１を貼シつけるとき、製造バラツ
キで、外板６又は断熱体パック１の平滑度が出ていない
と、外板６と断熱体パック１との間に隙間が出来、発泡
断熱材９を充填した時、この隙間に断熱材９が入シ込み
、未充填部１ｏを作る。この未充填部に断熱材９のＲ〜
１１がたまり、外気が下がると未充填部が大気圧より低
くなり外板１の変形となる問題点を有していた。Problems to be Solved by the Invention When attaching the heat insulator pack 1 to the outer panel 6, if the outer panel 6 or the insulator pack 1 are not smooth due to manufacturing variations, the outer panel 6 and the insulator pack 1 may be damaged. 1, and when the foamed heat insulating material 9 is filled, the heat insulating material 9 enters this gap, creating an unfilled portion 1o. R~ of the insulation material 9 in this unfilled part
11 accumulates, and when the outside air drops, the pressure in the unfilled area becomes lower than atmospheric pressure, which causes the outer panel 1 to deform.
本発明は上記問題点に鑑み、断熱体パックに起因する外
観変形を防いだ断熱箱体を提供するものである。In view of the above-mentioned problems, the present invention provides a heat insulating box that prevents deformation in appearance caused by the heat insulating pack.
問題点を解決するための手段
上記問題点に鑑み、外板又は内板と断熱体パックを発泡
ホットメルト接着材にて接合するものである。Means for Solving the Problems In view of the above-mentioned problems, the outer panel or inner panel and the heat insulating pack are bonded together using a foamed hot melt adhesive.
作 用
その作用は、発泡ホットメルトであるから、所定の厚が
確保できかつ、接合力を有するので断熱体パックと外板
とを接着しかつ隙間を生ぜることかない。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.
