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. When the can is in a filling position, liquid flows from the reservoir and through the axial bore of the cylindrical housing, the valve control, the female valve, the dip tube depending downwardly from the female valve, and into the can.

[ What is claimed is:] [1.] In an apparatus for charging a pressurized aerosol can with a liquid product, the aerosol can having a female valve and a dip tube depending downwardly from the female valve and into the can, which comprises a support means for positioning the aerosol can for a filling position, a liquid reservoir spaced above the support means, and means for selectively drawing liquid product from the reservoir to the can when in a filling position; the improvement comprising: (a) a substantially cylindrical housing engageable with and extending from the reservoir and having an axial bore for liquid communication with the reservoir; (b) valve control means normally biased to a closed position and establishing liquid communication between the reservoir and the can when in a filling position, said valve control means having (i) a valve body disposed in said axial bore of said cylindrical housing and having a central opening in liquid communication with said axial bore, and (ii) a hollow injector pin extending longitudinally from said valve body and concentrically arranged with said central opening and terminating with at least one aperture, said injector pin adapted to be received by the female valve when the can is in a filling position; and (c) means to retain said valve control means in said axial bore of said cylindrical housing; whereby when the can is in a filling position, liquid flows from the reservoir and through said axial bore of said cylindrical housing, said valve control means, the female valve, the dip tube, and into the can.
