Abstract
Filling apparatus for female valve type precharged aerosol cans includes an improved check valve construction that effectively reduces leakage and blow back while being both simple and economical. The valve comprises a seat formed of PTFE in the configuration of an O-ring. A can carrier assembly below the filling head supports the can in coupled relation with the filling head. The can carrier utilizes a relatively short compression spring to lift the can into its coupled relationship with the filling head and to laterally stabilize the lower end of the can without auxiliary guides and the like such that the carrier avoids the need for extraneous manipulation of elements other than the can itself when the can is being loaded or unloaded into the apparatus and the carrier cannot be jammed by spilled material.
