<P>PROBLEM TO BE SOLVED: To provide a sealing device easily attachable to/detachable from a cylindrical communication port of a container. <P>SOLUTION: An eccentric cam 20 is rotated in the direction wherein its lifting quantity is increased by lever 22 operation in the state where a cylindrical mouthpiece 30 is inserted into an insertion part of an adjustment ring 14, to thereby press a plunger 18 to the seal ring 16 side. Since movement to one side and to the outer circumferential side of the axial direction of the seal ring 16 is constrained by the adjustment ring 14, the seal ring 16 pressed by the plunger 18 is deformed so as to be expanded to the inner circumferential side. The seal ring 16 can be stuck to outer circumferential part of the cylindrical mouthpiece 30 by deformation of the seal ring 16. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
