Abstract:

In accordance with the present invention, the filling apparatus for charging a pressurized aerosol container with a liquid product utilizes a male injector depending from a liquid reservoir in conjunction with a female valve of the container. The aerosol can is positioned or adjusted between a can non-filing position and a filling position, and pressure selectively draws liquid from the reservoir to the can when in a filling position. A substantially cylindrical housing engageable with and extending from the reservoir has an axial bore for liquid communication with the reservoir. A valve control having a valve body disposed in the axial bore of the cylindrical housing and having a central opening in liquid communication with the axial bore, includes a hollow injector pin extending longitudinally from the valve body and concentrically arranged with the opening of the valve body and terminates with at least one aperture. The valve control is biased to a closed, no-filling position, and when the can is in a filling position the injector pin is adapted to be received by the female valve, thereby establishing liquid communication between the reservoir and the can. A locking nut retains the valve control in the axial bore of the cylindrical housing.
