Claims

[Claims for Utility Model Registration] (1) A jet head 3 is mounted on the upper end of the valve stem 7, and the jet port of the jet head 3 is connected to the fluid conduction path of the valve stem 7, and the valve stem 7 The inner circumferential end of the stem rubber 8 is brought into contact with the lower inflow port portion of the valve seat portion 10, and the outer circumferential end of the stem rubber
and the upper end of the valve fitting throttle part 2 in the center of the mountain cap 1, and the vertical groove inside the hakama-like hanging part 4 provided at the lower part of the jet head 3 and the valve fitting part. The vertical grooves on the outside of the up-throttle portion 2 are arranged so as to be vertically movable along each other, and by pressing down the jet head 3, a part of the valve that is normally closed can be opened. By providing a fluid conduction path penetrating from the top to the bottom, pressure filling can be performed from the fluid conduction path of the injection head 3 to the back side of the valve fitting constriction rising portion 2 as a flow path during pressure filling, After the contents have been used, the jet head 3 is rotated relative to the mountain cap 1, thereby interfering with the vertical grooves on one side and the other side of the vertical grooves, creating a space in the vertical direction, and releasing residual gas. This is how an aerosol valve is made. (2) By making the upper surface of the valve fitting constriction part 2 in the center of the mountain 1 into an inverted funnel shape, the stem rubber 8 disposed inside it is always directed upward by the internal pressure inside the aerosol cylinder. The aerosol valve according to claim 1 of the utility model registration, characterized in that it is crimped to prevent leakage.
