、保温容器１を構成していた。The filling of the heat insulating material is carried out separately and independently for each of the drum body 2, the two-part lid 6, and the lower lid 4, and the drum main body 2, the upper lid 6, and the T-portion are each formed separately. are doing. Then, the upper cover body 6 and the lower cover body 4 are fitted into the openings on both sides of the drum body 2, respectively, and are tightened and fixed by tightening parts such as bolts 5 as shown in the figure. The drum body 2 and the upper and lower lids 6, 4 are closely fixed to each other by welding means such as seam welding to form the heat insulating container 1.

と上・下部蓋体６，４との組付は工程も必要とされる。Most importantly, foamed materials such as urethane foam are much better than glass wool in terms of heat retention performance, but in order to foam, a formwork that can withstand the foaming pressure is required. However, assembling the formwork was a very time-consuming task. Moreover, the foaming process needs to be performed on each of the drum body 2, the upper lid 6, and the lower lid 4, and the foaming process must be performed on the drum body 2 after foaming.
Assembling the upper and lower lid bodies 6 and 4 requires additional steps.
しだがって、発泡樹脂を用いたこの種保温容器１は、保
温性能の割には高価なものであった。Therefore, this type of heat-insulating container 1 using foamed resin is expensive considering its heat-insulating performance.

The resulting condensation arrives on the inner and outer members 3a, 4a, 31), 411, and therefore the inner and outer members 3a+43+3h, 4
1. Corrosion occurs and the upper and lower lid bodies 6, 4 deteriorate.
There was a problem in that, in addition to forming holes, the temperature of this glass wool portion decreased due to the dew condensation, resulting in a decrease in heat retention performance. Moreover, since the soil/lower lid bodies 6, 4 are simply fitted to the drum body 2, there is a problem in that the packing density of the glass cooler at the joint portion becomes coarse, which significantly reduces the heat insulation effect.

外治具によって防止する。In this experimental example, urethane foam was used as the foamed resin, and the material of the inner cylinder 6 was made of stainless steel (sus3o4) with a plate thickness of 0.5 mm. In the figure, the vertical axis shows the foaming pressure (1 (V)) of the urethane foam, and the horizontal axis shows the air pressure (kg/ca) inside the inner cylinder 6. When the pressure was in the relationship shown by the solid line, it was possible to perform the most suitable molding process of urethane foam.Furthermore, the internal pressure of the inner cylinder 6 was in the range +1 (0.35 to 0.5 kg/cl).
) Good foam molding can be performed in the range 0 (
0.35 kg/c4 or less), the inner cylinder 1 deforms inward due to the foaming pressure of the urethane foam, and the internal pressure of the inner cylinder 6 is higher than the area B (region 1) (0.5 kg/c4 or less).
crlr or higher), contrary to the case described above, the foaming pressure of the urethane foam is low, so the inner cylinder 6
It has become clear that the outer cylinder 8 is deformed as shown in FIG.
