PROBLEM TO BE SOLVED: To provide a spray button for an aerosol container wherein when in use, an operation part can be projected from the top side of a shoulder cover by merely rotating the shoulder cover. SOLUTION: A shoulder cover 40 is mounted to the aerosol container 1 so as to be circumferentially rotatable, and a button cap 30 is fitted on a head part 13 of a spray button body 10 located above a spray port 12a in such a manner that the inner periphery of the cap 30 is threadedly engaged with the outer periphery of the head part 13, while an opening 43 is formed at the central portion of the upper surface of the cover 40 to allow the cap 30 to protrude. A rail or a rail engaging groove for engagement with a rail engaging groove or rail formed on the outer periphery of the cap 30 is provided on the shoulder cover 40 to allow the cap 30 to upwardly move through the opening 43, while the cap 30 is being rotatably driven. The rotational operation range of the cover 40 is set so that the cap 30 is rotated and driven to a normal position where the upper surface of the cap 30 is substantially coplanar with the upper surface of the cover 40 and to a use position where the cap 30 protrudes upwardly from the cover 40. At the use position, a spray window 44 is opened in a shoulder region facing the spray port 12a. |
