  • Patent number: 5871297
    Abstract: A fluid dispenser comprises an applicator portion, a handle portion, a pump, a valve, a first piston, a first resilient device, a second piston, and a second resilient device. The handle portion defines a pump support section and a reservoir. The pump support section includes the pump and a premeasure cavity. The valve is moveable between a normally closed position and an open position. The first piston moves in the reservoir and has the first resilient device biasing the piston for pushing fluid from the reservoir to move the valve to its open position so that fluid flows from the reservoir to the premeasure cavity to fill the premeasure cavity with a first premeasured charge of fluid. The valve moves back to its normally closed position after the premeasure cavity is filled. The second piston moves in one direction in the premeasure cavity and pushes the first premeasured charge of fluid from the premeasure cavity to the applicator portion.
