PROBLEM TO BE SOLVED: To neatly arrange the appearance of an unopened cap in a form that the unopened condition of the cap can be definitely recognized. SOLUTION: The cap body 1 is screwed into a container upper section Ya so that an opening Yb of the container upper section Ya is shut by a closed cylindrical upper end. A ring body 2 has an engagement piece 20 which can be engaged with an ejection regulation protrusion section Yd formed on the base periphery of the container upper section Ya at a ring internal peripheral section downwardly. The cap body 1 and the ring body 2 are molded by injection molding of plastics by allowing either of them to go ahead of the other to allow the external surface of the ring body 2 to closely contact the internal surface on the cylindrical lower end side of the cap body 1, thus they are separably integrated. A plurality of window holes 16, 16 through which the ring body 2 can be visualized from the outside are formed on the cylindrical lower end side of the cap body 1. COPYRIGHT: (C)2004,JPO
