In order to generally prepare a sealed tank with a Teflon material of the cylinder possible hayeoyaman necessarily seal the opening necessarily associated with the tank, wherein the case of performing the welding in order to seal the opening portion of the tank also, but this is sealed by welding the Teflon material state it should configure and almost impossible, and also in part due to the development of welding technology in recent years by a method for bonding the opening of the tank, producing a sealed tank, but this also requires a welding height, because of using the method with welding and also after the contacting with the welding has a problem as it is non-resolvable.; The present invention is a hole in the center and the opening peripheral surface of the tank processing the screw, respectively, a threaded portion corresponding to the threaded portion onto, consisting of ring-like engaging portion integrally formed along the inner circumferential surface under the reinforcement portion to solve the problems as described above, by configuring a coupler formed by combining the combined image sphere, two tanks by way fitting to couple the tank to the respective threaded portion under it was possible, by producing a single tank.
