ABSTRACT:
The present invention provides a sealing structure for a testing vessel, comprising a lid member secured to a base and having an upwardly projecting insertion portion and a supporting portion; a cylindrical container detachably mountable on the lid member in an up-and-down direction, the container having a lower open end portion to which said projection can be mated and which can be supported by the supporting portion and on which a plurality of first radially outwardly extending locking portions and first notches are alternately formed along a circumference thereof; a clutch member which is attached to the base and rotatingly guided in an circumferential direction by a guide member and on which a plurality of second radially inwardly extending locking portions and second notches are alternately formed within the same angular range as that of the first locking portions and first notches; and an elevator means for lowering and lifting the container to mount and dismount the latter with respect to the lid member. Wherein, when the first or second locking portions are aligned with the second or first notches by rotating the clutch member, the container can be mounted on or dismounted from the lid member by lowering or lifting the container by means of the elevator means, and the container is non-detachably attached to the lid plate when the first locking portions are engaged by the second locking portions.
