  Further, a plurality of protrusions may be provided on the upper surface of the push button, and a gap may be formed between the coating body and the injection port by mounting the coating body on the projection. . By forming the space between the application body and the ejection port in this manner, it becomes possible to cause the aerosol content ejected from the ejection port to adhere widely to the application body facing the ejection port, Can efficiently apply the aerosol content to the surface to be coated.

  As described above, the present invention can prevent the push button from being pressed down by arranging the hinge portion at a position other than the above-described concave position, so that the push button is erroneously pressed when not in use and waste of the aerosol contents is eliminated. It is possible to prevent a situation where excessive consumption occurs or the surroundings are soiled by the aerosol content discharged by the pressing. Further, since the pressing of the push button can be controlled by the hinge portion and the concave portion of the rotating body, a simple and compact configuration can be achieved without requiring any other special configuration, and the manufacturing cost can be reduced. It can be kept low and can be conveniently carried when going out.
