Abstract:
A fluid flow control valve for use in a fluid applicator tipwhich is connectable onto an open end of a resiliently squeezable bottle, comprising: a valve body including a central flow aperture having a sealing seat; a separate sealing ball configured for coaxial alignment and seated retention against said flow aperture and said sealing seat, respectively, within the applicator tip with said sealing ball oriented downstream of fluid flow through said flow aperture; said valve body being normally biased closed by a spring acting against said sealing ball to permit fluid to flow through said flow aperture only when the bottle is squeezed to increase fluid pressure to unseat said sealing ball from said sealing seat; said sealing ball automatically re-seating against said sealing seat when there is no substantial pressure within the bottle thus preventing substantially all fluid flow therethrough; a metering cup positioned within the applicator tip between said spring and an elongated fluid passage of the fluid applicator tip and having a metering orifice formed through a bottom of said metering cup, said metering orifice being substantially smaller in diameter than that of said flow aperture whereby maximum fluid flow rate from the bottle through said fluid control valve is limited by said metering orifice.
