  • Patent number: 5857796
    Abstract: An applicator with reservoir is comprised of a reservoir having an open top and a flow cap threadably secured thereto. A closure valve snap fits onto the flow cap and thereafter threadably rotates about the flow cap between a closed and an open position. An applicator cap, having an applicator tip, such as a brush, a roller, or the like, is threadably secured to the closure valve. In a normally open position, the closure valve permits a fluid flow path between the reservoir and the applicator tip. In a normally closed position, the closure valve interrupts the fluid flow path.
