（従来の技術）
今日、透過性の強い物質を収容する容器を製作する場合
、容器母材の内部に透過防止膜を有する多層構造とする
ことが行われている。(Prior Art) Today, when manufacturing a container for containing a highly permeable substance, a multilayered structure having a permeation-preventing film inside the container base material is used.

より、中空容器を得る方法である。By the way, when manufacturing a hollow container having such a permeation-preventing membrane, a blow molding method has conventionally been widely adopted. This blow molding method extrudes a multilayer resin called a multilayer parison into a cylindrical shape into opposing molds, closes the mold and seals both ends of the cylindrical resin, and then injects air, etc. into the resin. This is a method to obtain a hollow container by inflating the resin according to the shape of the mold.

伴う切粉を外部に排除するのが困難であった。(Problems to be Solved by the Invention) However, due to the blow molding method, the plate thickness becomes uneven, the weight increases, and the capacity of the container decreases. Also,
When performing secondary processing such as attaching parts to the inside and drilling holes, it is necessary to perform these on a hollow object after blow molding, which makes processing difficult and requires cutting during processing. It was difficult to remove the powder to the outside.

At the peripheral flange portion 8.8 in 1, the inner surface material 3 and the outer surface material 6 of each divided body 1 and the inner surface material 3.3 of both divided bodies 1.1 are connected to each other.
Since the outer surface materials 6 and 6 and the inner surface material 3 and the outer surface material 6 are welded together, all the welded parts in the flange portion 8.8 are made of the same polyethylene resin, and this welding of the same materials increases the welding strength. In addition, airtightness can be improved. In addition, when the welding surface 8a of the flange portion 8 is heated during welding of both the divided bodies 1.1, the joints of the inner surface material 3 and the outer surface material 6 of each divided body 1 are melted by the heat, and the nylon resin is melted. Since they are welded to each other so as to confine the membrane 4,
Peeling of the permeation prevention film can be effectively prevented.

きる。Furthermore, since the hollow container is constructed by welding the pair of divided bodies 1.1, when molding each divided body 1, it is possible to form the plate with uniform thickness (particularly in the example of the above manufacturing method, the plate This is advantageous because the thickness can be controlled to be constant between the upper and lower molds). Therefore, compared to blow molding or the like, the thickness of the hollow container can be made more uniform. Furthermore, as a result of the uniform plate thickness of the hollow container, the weight of the hollow container can be reduced and its capacity can also be increased.
