PROBLEM TO BE SOLVED: To provide a cover provided with a lock wherein an open/closure operation part of a cover body and an injection port cover is not exposed. SOLUTION: In an insulated pot 12 wherein a pouring liquid injection port and a cover 8 thereof are arranged on a cover body 6 to open or close an upper side opening of an insulated container, a cover 13 is attached to cover open/closure operation tools 15a, 15b of the body 6 and the cover 8 as well. A lock 18 is mounted to the cover 13, wherein the lock 18 can be releasably locked in the body 6 or in an irregular portion of the cover 8. When the cover 13 is locked, the cover 13 cannot be removed, and when the cover 13 is unlocked, the cover 13 can be removed. Thus, when the cover 13 is locked, the cover 13 cannot be removed from the body 6, and hence the body 6 and the cover 8 cannot be opened. That is, foreign matters or chemicals are prevented from being mixed into the pot, and a drink in the container 4 can be safely used.
