ツプ。 The cap shell consists of a disc-shaped top plate, a cylindrical part that hangs down from the periphery of the top plate, and a liner provided on the inner surface of the top plate of the cap, and is attached to the mouth of the container. In the cap for sealing the cap, the liner is provided with an outer annular protrusion and an inner annular protrusion, and the inner circumferential surface of the outer annular protrusion extends upward at an angle of 1° to 30° with respect to the central axis of the cap. The inner circumferential edge surface of the lower end forms an arc of a predetermined radius in a plane including the central axis, and the outer circumferential edge of the upper end surface of the container opening extends over the entire length. The inner annular protrusion is formed to have a size corresponding to the arcuate portion, and the outer circumferential surface of the inner annular protrusion is inclined upwardly and gradually outward in the radial direction, and the outer diameter of the lower end thereof is the same as the container opening. A cap characterized by a cap whose outer diameter is smaller than the inner diameter of the upper end of the cap, and whose outer diameter is slightly larger than the inner diameter of the end of the container mouth.
