Claims

[Scope of utility model registration request]

Due to the pressure of the stem of the valve of the aerosol container,
In a metering valve for an aerosol container that sprays a certain amount of liquid present in the space 3s between the stem 1 and the housing 3, an elastic ring or packing is fixed to the lower end of the stem or inside the housing, Alternatively, the metering valve is characterized in that the stem or housing itself has elasticity, and the lower end 1b of the stem and the flow path at the lower end of the housing 3 are elastically frictionally engaged when the stem is depressed.
