<P>PROBLEM TO BE SOLVED: To provide a vessel with a fitting cover which enables the cover to be easily attached to and removed from the vessel body and is capable of sufficiently preventing a liquid from leaking from a clearance between the vessel body and the cover. <P>SOLUTION: The vessel 10 with the fitting cover includes the vessel body 11 having a flange 12 mounted in the circumference of an opening 11a and the cover 15 attachable to and removable from the vessel body 11 and fitting to the flange 12. The flange 12 has an upper surface 12a extending outward of the opening 11a over the whole circumference of the opening 11a, and a groove 12b surrounding the opening 11a is mounted on the upper surface 12a. When the flange 12 and the cover 15 fit to each other, an annular space S1 surrounding the opening 11a is defined by the groove 12b and the inner surface 15a of the cover 15. <P>COPYRIGHT: (C)2012,JPO&INPIT |
