PROBLEM TO BE SOLVED: To provide a button cap which can be easily attached to another aerosol container.SOLUTION: A push button 20 is disposed at the substantially central part of a cap body 10, and the cap body 10 comprises an inner cylindrical member 12 and an outer cylindrical member 11 which vertically slides outside the inner cylindrical member 12. A holding part 13 is provided at the lower end part of the inner cylindrical member 12. A plurality of notches 13k are provided in the holding part 13 in a vertical direction, and a plurality of notches 15k are also provided at the upper end part of the inner cylindrical member 12 in the vertical direction. The outer cylindrical member 11 has a holding part joining part 14 at the lower end part, and a pressing part for pressing the upper end part of the inner cylindrical member 12 toward a radial central part at the lower end part. A pressing force receiving part is provided in the inner cylindrical member 12 slightly above the pressing part. When the outer cylindrical member 11 slides upward, the holding part 13 of the inner cylindrical member 12 expands, and thereby a cap is detached from an upper end peripheral part J of an aerosol container Y. When the outer cylindrical member 11 slides downward, the holding part joining part 14 inhibits the expansion of the lower end holding part 13 of the inner cylindrical member 12, and thereby the cap is attached. |
