PURPOSE: A dual cooking vessel is provided to prevent food from being boiled over by blocking flame flowing upward through an adjusting hole. CONSTITUTION: A dual cooking vessel includes an inner pot(20), an outer shell(30), and a movable piece(40). The inner pot has a food receiving part and a rim part(23). The rim of outer shell is extended outward in a radial direction. The outer shell is combined with the outside of the internal vessel. A space part for guiding ascending flame is interposed between the outer shell and the inner pot. A plurality of regulating holes(31) are formed in the rim part of the outer shell. The movable piece is rotatable between the rim of the outer shell and the rim of inner pot, thereby controlling the opening and closing the regulating holes. |
