Abstract

PURPOSE: To enhance sealing effect by a method wherein a tightening force acting on a cap against a container main body is utilized for radially expanding the whole periphery of a gasket so as thereby to pressure-contacting the outside peripheral surface of the gasket to the main body and the cap.
CONSTITUTION: With a cap 3 tightened against a container main body 1 by bolts, the tightening force is transmitted to an expanding member 12a in contact with the lower face of the cap 3 and to an expanding member 12b supported on a step portion 13 of the main body 1, so that the members 12a and 12b are moved toward each other. Attending on this movement, the top and bottom end portions on the internal peripheral side of a gasket 4 slide along tapered faces 14a and 14b of the members 12a and 12b respectively, so that the whole periphery of the gasket 4 is expanded from inside to outside. Therefore, pressure contact portions 9 of the gasket 4 are pressure-contacted to receiving surfaces of the main body 1 and the cap 3, providing a sealing effect during initial boosting.
