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.
Claims20
An applicator with reservoir comprising:
- a first fluid reservoir having a closed bottom and a first open top;
- a first shaft having an open bottom and a top for receiving the applicator tip;
- a second fluid reservoir located intermediate the open bottom and the top;
- a duct connecting the second fluid reservoir and the top;
- a cap, having a first open base and a second shaft with first male threading on the second shaft's outer surface and a second open top, threadably attached to the first open top of the first fluid reservoir;
- a plurality of prongs extending upwardly from the second open top;
- a plug situated atop the plurality of prongs in spaced apart relation to the second top;
- a closure valve, having a second open base with female threading on the second base's inner surface and a third shaft with second male threading on its outer surface for threadably receiving the open bottom, removably securable to the cap such that the first male threading mates with the female threading and permits rotation of the closure valve about the cap such that rotation of the closure valve lowers the closure valve toward the cap and the plug is received within the second fluid reservoir for disrupting fluid communication between the first fluid reservoir and the applicator tip and such that counterrotation of the closure valve raises the closure valve away from the cap and withdraws the plug from the second fluid reservoir and permits fluid communication between the first reservoir and the applicator tip.

An applicator with reservoir consisting essentially of:
- a first fluid reservoir having a closed bottom and a first open top;
- a first shaft having an open bottom and a top for receiving the applicator tip;
- a second fluid reservoir located intermediate the open bottom and the top;
- a duct connecting the second fluid reservoir and the top;
- a cap, having a first open base and a second shaft, the second shaft having a first section with a first diameter and a second section with a second diameter that is different than the first diameter, with first male threading on the second shaft's outer surface and a second open top, threadably attached to the first open top of the first fluid reservoir;
- a plurality of prongs extending upwardly from the second open top;
- a plug situated atop the plurality of prongs in spaced apart relation to the second top;
- a closure valve, having a second open base with female threading on the second base's inner surface and a third shaft with second male threading on its outer surface for threadably receiving the open bottom, removably securable to the cap such that the first male threading mates with the female threading and permits rotation of the closure valve about the cap such that rotation of the closure valve lowers the closure valve toward the cap and the plug is received within the second fluid reservoir for disrupting fluid communication between the first fluid reservoir and the applicator tip and such that counterrotation of the closure valve raises the closure valve away from the cap and withdraws the plug from the second fluid reservoir and permits fluid communication between the first reservoir and the applicator tip.
