An aerosol dispenser having a valve for dispensing product through a valve stem. The valve stem is protected by a sheath, to reduce breakage. The sheath extends equal to or above the height of the valve stem, to absorb axially compressive loads and side impact loads. The sheath can occur in the aerosol dispenser, an aerosol container, an outer container, a preform and/or in the valve. The aerosol dispenser can include bags, pistons and dip tubes. |
