Aerosol dispenser

摘要

An aerosol dispenser has a housing adapted to hold an aerosol under pressure relative to a pressure outside of the housing. The housing has an interior chamber surrounded by interior walls and an opening to the outside. A stopper assembly is disposed within the housing and shaped to substantially conform to the shape of the housing. The stopper assembly is movable from a first position, in which the stopper assembly is substantially in contact with the interior walls of the housing so as to seal off any means of egress for the aerosol, from the interior chamber to the outside of the housing, to a second position, in which the stopper assembly is substantially out of contact with the interior walls so that at least one means of egress for the aerosol is established., At least one means of egress is traceable from the interior chamber to the opening to the outside.
