VESSEL LID

PROBLEM TO BE SOLVED: To enable an outer lid to pivot sufficiently smoothly from an open position to a closed position and prevent a second hinge means (44) connecting the inner lid to a discharge tube from being damaged in a relatively short time in a vessel lid (2) which includes a body (4) and an outer lid (6) pivotably connected to the body, the discharge tube (22) being arranged on the upper surface wall of the body, the inner lid (46) being pivotably connected to the discharge tube and being opened and closed in accordance with the opening and closing motion of the outer lid, and which is integrally formed of a synthetic resin. SOLUTION: A securing protrusion (50) is formed on each of both sides of the inner surface of the inner lid. A receiving protrusion (54) protruding upward from both the side surfaces is formed on the discharge tube. The securing protrusion has such a shape that the securing protrusion can elastically get over the receiving protrusion when the inner lid pivots from the closed position to the open position. The securing surface (52) is formed on the securing protrusion and/or a receiving surface (56) is formed on the receiving protrusion. When the inner lid is located at the open position, the securing surface and/or the receiving surface extends downward slantingly in the direction for the same to go away from the first hinge means.
