Abstract
A valve assembly is disclosed for use with an aerosol container having an integral plastic spring acting between the valve stem and the valve body. The valve body is disposed within the aerosol container adjacent a sealing gasket having a central aperture for receiving a valve stem extending therethrough. The valve stem has a valve stem sealing base for movement within an internal body cavity of the valve body to seal the valve stem when the base engages the sealing gasket and for enabling fluid flow when the base is displaced from the sealing gasket. The invention incorporates a plurality of resilient legs extending from the valve stem base for cooperation with an inclined surface either being a tapered or curved surface extending from the valve body to bias the stem sealer into engagement with the sealing gasket.
