<P>PROBLEM TO BE SOLVED: To provide an aerosol button and an aerosol cap which can obtain proper and stable spray and has molds for resin molding excellent in durability. <P>SOLUTION: The aerosol button and the aerosol cap include a passageway for guiding contents from a valve stem through a spray opening and out of the aerosol button, and protruding pieces 35 that extend in the spraying direction from the peripheral edge of the spray opening. The passageway includes an introduction passage 41 that extends along the valve stem and an emission passage 42 that bends in an intersecting direction to the introduction passage and opens to the spray opening 40. The spray opening 40 is disposed near the valve stem. The protruding pieces 35 are disposed facing one another, and are positioned so that facing edges 351 are positioned to suppress the dispersion of spray in the direction in which the pieces face one another, and to allow the dispersion of spray in the direction perpendicular to the direction in which the pieces face one another. When viewed from the direction orthogonal to the direction in which the pieces face one another, the width of the facing edges 351 is substantially equivalent to the diameter of the spray opening. <P>COPYRIGHT: (C)2012,JPO&INPIT |
