The outer panel 2 is located on the outer side of the inner panel 1 and a foaming space 3 is formed therebetween, and the foaming space 3 is filled with a foam body 31; the outer panel 2 is welded from a plurality of plate members 21, specifically, the outer panel 2 is the bottom plate of the bottom frame 100 and includes a plurality of plate members 21 extending along the longitudinal direction X, and the plurality of plate members 21 are distributed along the longitudinal direction X, wherein the plate members 21 are made of corrugated plates; both ends of each plate member 21 are respectively bent inwardly and integrally extended to form a connecting portion 211, and the connecting portion 211 extends into the foaming space 3 and is in close contact with the foam body 31, which can increase the contact area between the foam body 31 and the panel member 21, thereby enhancing the adhesion between the foam body 31 and the panel member 21, preventing the foam body 31 from falling off, and ensuring the thermal insulation effect of the container, and the connecting portions 211 of two adjacent plate members 21 are fixedly connected, which can enhance the structural strength of the outer panel 2 and further extend the service life.

[0024] like Figures 1 to 3 As shown, the free end of the connecting portion 211 is integrally bent and extended to form an extension portion 212. An angle is formed between the extension portion 212 and the connecting portion 211, and the two form a hook portion 20. The hook portion 20 is in close contact with the foam body 31, that is, the plate 21 hooks the foam body 31 through the hook portion 20, further preventing the foam body 31 from falling off. In this embodiment, the height H of the connecting portion 211 is 20~50mm, and the length L of the extension portion 212 is 20~50mm. The two adjacent connecting portions 211 are welded and fixed, and the free ends of the two are bent and extended in opposite directions to form an extension portion 212. The extension portion 212 is perpendicular to the connecting portion 211, which can further increase the contact area between the foam body 31 and the plate 21, so that the adhesion between the foam body 31 and the plate 21 is further enhanced. Of course, in other embodiments, such as Figure 4 As shown, the free ends of two adjacent connecting portions 211 can be bent and extended in the same direction to form an extension portion 212.
