CONTENT INJECTION OPERATION BUTTON AND AEROSOL-TYPE PRODUCT HAVING CONTENT INJECTION OPERATION BUTTON

WIPO Patent Application WO/2020/066586

A1

A content injection operation button having an annular injection port according to the present invention facilitates uniform atomization of content, high deposition rate of content to an injection target such as an affected part, and silencing the sound of content injection. An injection port A is set between an annular nozzle 2 and a core 1c. A horizontally linear, content passage portion leading to the injection port A comprises an upstream-side annular lateral passage portion B that has a large content passage cross-sectional area between the upstream-side annular lateral passage portion and the core 1c and weakens the flow of the content, and a downstream-side annular lateral passage portion C provided on the downstream side of the upstream-side annular lateral passage portion B, the downstream-side annular lateral passage portion C having a shape where the content passage cross-sectional area continuously decreases in the direction of the flow of the content. How the content passage cross-sectional area of the downstream-side annular lateral passage portion C decreases is determined by an annular nozzle taper surface 2a whose inner diameter becomes small toward the injection port A, and the core 1c.
