Claims

[Claims for Utility Model Registration] The cap 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. In the cap that is attached to the mouth of the container and seals the mouth of the container, the liner is provided with an outer annular protrusion and an inner annular protrusion, and as the inner peripheral surface of the outer annular protrusion goes upward, it gradually moves radially inward. The inner diameter of the lower end of the outer annular protrusion is larger than the outer diameter of the end of the container mouth to which it is attached, and the inner diameter of the base end of the outer annular protrusion is larger than the outer diameter of the end of the container mouth. is formed smaller than the outer diameter of the end of the outer annular protrusion, and the angle between the inner circumferential surface and the outer circumferential surface of the outer annular protrusion is 65° or less, and the outer circumferential surface of the inner annular protrusion is directed upward. The outer diameter of the lower end of the inner annular protrusion is smaller than the inner diameter of the end of the container mouth to which it is attached, and the proximal end of the inner annular protrusion is 1. A cap characterized in that its outer diameter is larger than the inner diameter of the end of the container mouth, and the inner annular protrusion has a tapered cross-sectional shape that gradually becomes thinner toward the lower end.
