るエアゾール用バルブ。2. A stem peripheral wall 5 is formed by an inner peripheral surface of a stem 3 having an upper end protruding from the upper surface of the container body so as to be able to move up and down while being biased upward, and an annular plate-shaped valve body 4 fixed to the upper end portion of the container body. And a discharge valve 7 formed by closing the discharge valve hole 6 that is opened and closed so that the discharge valve 7 is opened by pushing down the stem 3 and the liquid in the container is jetted from the upper end of the stem 3 by gas pressure. In the aerosol valve configured as described above, a vent hole 22 for opening the lower end of the stem 3 is bored, and a rod plug 23 for closing the vent hole is provided. The stopper 23 is provided with a small diameter portion 23b standing upright from the upper end of a large diameter portion 23a fitted in a liquid tight manner on the inner circumference of the stem peripheral wall 5 below the discharge valve hole 6 with a clearance for liquid circulation around the periphery. Small diameter part 23b
The upper end is protruded from the upper end of the stem 3 so that a predetermined width can be pushed in, and a vertical groove 25 for releasing the upper surface and the outer surface is vertically provided on the outer peripheral upper portion of the large diameter portion. An aerosol valve, characterized in that, by pushing down, the inside of the container and the inside of the stem communicate with each other through the vertical groove 25.
