<P>PROBLEM TO BE SOLVED: To provide an aerosol button, an aerosol cap, and an ejection nozzle tip for an aerosol button capable of effectively preventing the content ejected from the ejection opening from adhering to a lower portion in front of the ejection opening. <P>SOLUTION: An aerosol cap is provided with an aerosol button and a cap body. The aerosol button is provided with an ejection opening 4 which can eject the content of an aerosol container, a flow path which connects the ejection opening 4 and a valve stem, and a pair of upper and lower protrusions 5 which is provided so as to extend in the ejection direction from the peripheral edge of the ejection opening 4 and which laterally spreads the content ejected from the ejection opening 4. The shape of both the protrusions 4 is determined so that, in a vertical cross-sectional view, the area S1 of a region above a horizontal plane G2 passing through the center O of the ejection hole 4 in the gap 50 formed between both the protrusions 5 and extending in the horizontal direction is greater than the area S2 of a region below the horizontal plane G2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
