PROBLEM TO BE SOLVED: To improve the opening/closing operatability of a lid by a method wherein a lid is rockably provided on a cap main body, and at the same time, a gear is formed on the outer periphery of a rocking shaft of the lid, and in the meantime, a gear to be engaged with the gear of the rocking shaft, is formed on an operation piece which is provided on the cap main body, and the lid is opened/closed by rocking it by the engagement between both gears. SOLUTION: A cap A which is fitted on a shake-out container, is fitted on a container B by screwing a threaded part 11 of a cap main body 10 on the mouth part of the container B, and on the upper surface of the cap main body 10, a lid 13 is rockably provided, and when the lid 13 is closed, a protuberance 14 on the internal surface of the lid 13, is fitted in a shake-out hole 12, and closes the hole 12. A sunk part 17 is formed on the rear surface of the cap main body 10, and an operation piece 18 rises from the lower end of the sunk part 17 with a hinge part. On the top of the operation piece 18, a gear 19 is formed, and this gear 19 is engaged with a gear 15 of the lid 13, and when the operation piece 18 is pressed, both gears 15, 19 are engaged, and by the engagement, the lid 13 is opened. Also, when the pressing force for the operation piece 18 is released, the lid 13 is closed by a spring piece 20. |
