王冠。 It consists of a metal crown shell having a top wall and a skirt wall hanging from its periphery, and a synthetic resin sealing liner disposed on the inner surface of the top wall of the crown shell, the liner having concentric inner and outer annular protrusions. The inner annular protrusion has an inner circumferential surface extending substantially parallel to the crown axis and an angle α of 40 to 50 degrees with respect to the crown axis, and the inner annular protrusion slants upward and radially outward. The inner diameter d1 of the inner annular protrusion is 0.720 with respect to the inner diameter D of the crown shell.
D to 0.750D, and the lower half of the outer annular ridge is defined by an arc having its center within the outer annular ridge, and the upper half has its center outside the outer annular ridge. an inner circumferential surface defined by a circular arc, an outer circumferential surface extending substantially parallel to the crown axis, and a flat lower surface extending substantially perpendicular to the crown axis; d2 is set to 0.952D to 0.972D with respect to the inner diameter D of the crown shell, and the radial thickness t2 of the flat lower surface is 0.
．． 60 to 0.80 mm, and the average radial thickness t1 of the outer annular protrusion is set to 0.80 to 1.20 mm.
