Abstract
A dispensing apparatus for nasal administration of an aerosol product is provided with a housing for a pressurized dispensing container with a pivoted cover which in its closed position encloses an outlet duct of the housing. The container is received in a chamber of the housing which is sealed by a bellows portion. An openable closure provides access to the chamber for insertion and removal of the container. The apparatus seals the chamber against ingress of foreign matter between use and encloses the outlet duct to prevent soiling.
