CONTENT DISCHARGE MECHANISM AND AEROSOL PRODUCT PROVIDED WITH SAME

WIPO Patent Application WO/2017/115546

A1

The present invention minimizes deformation corresponding to a stationary mode of a lower central edge part of a stem gasket in an aerosol-type content discharge mechanism, reliably holds the stationary mode position of a stem, and maintains a sealing effect between the stem and the stem gasket. The stem (1) of this content discharge mechanism is provided with vertical rib sections (1f) each extending downward and outward from the lower edge side of an annular shoulder section (1d). A vertically recessed space (1h) comprising a tapered bottom surface (1j) inclined downward and outward so as to continue from the annular shoulder section (1d) is configured between adjacent vertical rib sections. The vertically recessed space (1h) acts as a fall space area for residual content that adheres to the annular shoulder section (1d) and that is scraped off by the stem gasket when returning to the stationary mode. When in the stationary mode, a central opening lower circumferential surface (3b) of the stem gasket (3) is in close contact with the annular shoulder section (1d), and an inner edge-side annular bottom surface (3c) in the vicinity of the exterior of the stem gasket (3) is in close contact with a horizontal upper surface (1g) of the vertical rib sections (1f).
