Claims

[Scope of utility model registration request]

It has an upper stopper that is airtightly integrated into the upper opening of the container body, and a bottomed cylindrical valve chamber that is integrally molded inside the upper stopper, and a valve chamber that is opened at the center of the bottom of the valve chamber. A through hole communicating into the main body, a discharge tube inserted into the valve chamber via a spring and having an upper end protruding outward from the upper opening of the valve chamber, and a bottomed discharge hole formed in the center of the discharge tube. an annular groove formed on the outer circumferential surface of the discharge tube; a valve opening opened in the annular groove and communicating with the discharge hole; The guide screw is pressed against the upper surface of the step formed integrally with the inner wall of the valve chamber, and the upper surface is screwed into the opening of the valve chamber to maintain airtightness with the inner surface of the valve chamber. In the aerosol valve, the aerosol valve is equipped with a disc-ring-shaped stem rubber that is fixed to the stem rubber, and a protrusion is provided on the upper surface of the stepped portion formed on the inner wall surface of the upper stopper, which is in contact with the outer peripheral edge of the stem rubber. At the same time, when the protrusion bites into the outer peripheral edge of the stem rubber, the surface pressure applied to the protrusion is distributed evenly so that the surface pressure received by the protrusion is not concentrated in one place and damages the surface of the stem rubber. An aerosol valve shield structure characterized by a smooth semicircular cross-section of the upper edge.
