Abstract:
An improved mounting cup and valve assembly combination for an aerosol canister, the combination comprising:a mounting cup having a perimeter curl for securing the mounting cup to an opening of a desired canister, the mounting cup having a pedestal portion with a centrally located aperture therein;a valve assembly having valve body with a product inlet communicating with an interior cavity of the valve body, a product outlet being formed in a valve stem, a base portion of the valve stem being at least partially supported within the interior cavity of the valve body, and at least one first radial orifice being formed in the valve stem, adjacent the base portion, to provide communication with the product outlet of the valve stem;the valve assembly being housed within the pedestal portion and being crimped thereto with a gasket being located between a perimeter sealing surface of the base portion of the valve stem and an adjacent inwardly facing surface of the pedestal portion with a portion of the valve stem, supporting the product outlet, protruding through an aperture provided in the gasket and the centrally located aperture of the pedestal portion;wherein at least one second radial orifice is formed in the valve stem at a position spaced from the base portion of the valve stem with the at least one first radial orifice located therebetween, and a compressible elastomeric member, having a solid continuous uninterrupted exterior wall without any voids therein, is located within the interior cavity of the valve body and is uncompressed when the product to be dispensed is flowing solely through the at least one first radial orifice to provide a first low product dispensing flow rate, and the compressible elastomeric member is at least partially compressed and directly contacts an adjacent surface of the bottom portion of the valve stem when the product to be dispensed flows through both the at least one first radial orifice and the at least one second radial orifice to provide a second coarse product dispensing flow rate.
