A pressurized vial for containing a medication and a foaming gas, a dose forming and ejecting sleeve telescoped around the vial, a dose releasing valve in one end of the vial having an operating button at the opposite end of the vial, a discharge opening for the dose of foamed medication in the end of the outer sleeve, and an applicator tip attachable within the discharge opening of the outer vial, characterized by an inwardly projecting portion on the tip which extends into the path of the valve element of the pressurized vial so that movement of the outer sleeve bearing the applicator tip beyond the dose dispensing movement of the sleeve will cause the end of the valve to engage the inner end of the applicator tip and eject the applicator tip from the sleeve without requiring exterior contact with the applicator tip.
