  When the exterior body of the container is molded with metal, a high-class feeling is imparted to the container itself, but it has been inevitably more expensive than a synthetic resin container. This exterior body required at least three parts, a main body cylinder, a fitting cylinder, and a cap. Of these, if the fitting part of the body tube and the cap of the fitting tube are molded integrally, the exterior body can be composed of two parts, eliminating the trouble of adjusting the color of each part, eliminating the assembly process, and causing the failure factor The cost was reduced significantly. If this is a synthetic resin container, it is possible to easily mold the fitting part of the main body cylinder and the cap integrally. However, since the strength is lower than that of a metal container, the wall thickness is increased. The outer diameter became thicker and it became a cheap image. When this is performed with a metal, it is impossible only by press working, and it is necessary to perform cutting work as post-processing, and conversely, it takes time and is not realistic.
