樹脂製の中空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 hollow container made of resin that has permeation resistance that prevents highly permeable substances such as gasoline and alcohol from permeating to the outside.

（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

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. By inflating the resin according to the shape of the mold,
This is a method of obtaining a hollow container.

In addition, when performing secondary processing such as attaching parts to the inside or drilling holes, it is necessary to perform these on a hollow object after blow molding, which makes the processing difficult and It was difficult to remove the chips to the outside.

As a hollow container, a pair of divided bodies each consisting of an inner surface material made of at least a synthetic resin, a permeation prevention film, and an outer surface material made of the same material as the inner material,
A flange portion is provided at the end edge of the inner surface material and the outer surface material expanded so as to wrap around the permeation prevention membrane, and at this flange portion, the outer surface materials and the inner surface materials of both divided bodies and the inner surface material and the outer surface material are separated. The structure is welded.

ことができる。(Function) With the above configuration, in the present invention, the hollow container is constructed by integrally welding the divided bodies, and the outer and inner materials of both the divided bodies are welded to each other, and the inner and outer materials are welded to each other at the welded portion. This eliminates the presence of foreign substances in the welded portion, increasing welding strength and improving airtightness and permeation resistance. Furthermore, even if the welded parts are slightly misaligned, the same materials will always be welded together. In this way, at the welded portion, the inner surface material and the outer surface material other than the permeation prevention film are welded together so as to wrap around the permeation prevention film, so that peeling of the permeation prevention film can be effectively prevented.

It can be done. Also,
Therefore, a reduction in the weight and an increase in the capacity of the container can be achieved.

Then, the inner and outer materials 3 and 6 of each divided body 1, the inner and outer materials 3 and 3 and the outer materials 6 and 6 of both the divided bodies 1 and 1, and the inner and outer materials 3 and 6 are welded together. There is.

Therefore, the welded parts of the flange parts 8, 8 are all made of the same polyethylene resin, and by welding these same materials together, welding strength and airtightness can be increased. Furthermore, as the welding surface 8a of the flange portion 8 is heated during welding of the two 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 the membranes 4 are welded to each other so as to be confined, peeling of the permeation prevention membrane can be effectively prevented.

容易に分割体１から排出除去することができる。 Further, since the hollow container is formed by welding the integral divided bodies 1, 1 at the peripheral flange parts 8, 8,
At the stage before welding, it becomes possible to attach various parts to the interior of the hollow container, or perform secondary processing such as drilling holes in the hollow container such as an injection port and a supply port. As a result, the secondary processing can be easily performed, and chips and the like generated during processing can be easily discharged and removed from the divided body 1.

ことができる。 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 a uniform thickness (especially 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. Further, as a result of the hollow container having a uniform plate thickness, the weight of the hollow container can be reduced and its capacity can also be increased.

However, in the case of facing outward, in the example of the manufacturing method described above, it is preferable because it becomes easier to press the welded parts when welding the two divided bodies 1, 1 together.

さらに、フランジ部をなくしてもよい。 Furthermore, the flange portion may be eliminated.
