ABSTRACT A piston for an aerosol container, particularly adapted for insertion through the top of the container; the piston includes an annular, cylindrical collar near its top end and a conical outwardly flaring flange atop the cylin- drical collar, with the flange flaring wider toward the top of the container, whereby the flange scrapes the container interior as it moves up; the cylindrical collar is more flexible than the conical flange to ease insertion of the piston and for more effective piston sealing despite the piston cocking in the container; anti-cocking means are provided on the piston.
