An atomizing fluid dispenser for delivering, via a spray nozzle, a substantially equal metered dose of fluid material for each dispensing operation. The fluid dispensing device includes a container with an interior fluid storage region therein. A metering housing, when depressed, generates a one-way flow from the interior fluid storage region of the container that serves to fill the predetermined volume of the chamber within the metering housing. When the metering housing is depressed a second time a substantially equal volume of fluid is dispensed from the container, while upon release, the metering housing is refilled by drawing fluid from the fluid storage region. A spray nozzle or atomizer is attached to the exit port of the dispensing device so that the liquid is delivered in metered fashion in spray form.

1. A fluid dispensing device, comprising: a flexible container having an interior fluid storage region therein and an opening extending from said interior fluid storage region to an exterior region outside the flexible container;a flexible metering housing in the opening of the flexible container, having a metering chamber therein with a predetermined volume, disposed in fluid communication with the fluid storage region via the opening;a first valve disposed between the container and the flexible metering housing to permit unidirectional fluid flow from the interior fluid storage region of the container into the metering chamber thereby filling the predetermined volume of the metering chamber;a second valve, having an output port, in fluid communication with the metering housing and permitting unidirectional fluid flow of a volume of fluid substantially equal to the predetermined volume of the metering chamber from the metering chamber to the exterior region of the container; anda spray applicator in fluid communication with the output port to deliver liquid in a metered fashion in a spray form. 2. The fluid dispensing device of claim 1, further comprising: means for dispersing fluid from the spray applicator about the exterior region of the container. 3. The fluid dispensing device of claim 2, wherein the means for dispersing is a layer of foam positioned about the container. 4. The fluid dispensing device of claim 2, wherein the means for dispersing is a layer of fabric positioned about the container. 5. The fluid dispensing device of claim 1, further comprising: a fluid conduit having a first end and a second end, the fluid conduit connected at the first end to the output port and at the second end to the spray applicator. 6. The fluid dispensing device of claim 5, wherein the output port and the spray applicator are on opposing sides of the container from one another. 7. The fluid dispensing device of claim 5, wherein the fluid conduit is routed through the interior fluid storage region of the container. 8. The fluid dispensing device of claim 1, further comprising: a fluid conduit disposed between the metering housing and the second valve. 9. The fluid dispensing device of claim 1, further comprising: a refill port connected to the container. 10. The fluid dispensing device of claim 1, wherein the first valve and the second valve are one-way check valves. 11. The fluid dispensing device of claim 1, further comprising: a strap connected to the container. 12. The fluid dispensing device of claim 1, further comprising: standoff means connected to the metering housing, the standoff means being proximal to the first valve to prevent the first valve from being blocked. 13. The fluid dispensing device of claim 12, wherein the standoff means is at least one leg. 14. The fluid dispensing device of claim 12, wherein the standoff means is a spring. 15. The fluid dispensing device of claim 1, further comprising: a frame attached to the container; and applicator material attached to the frame. 16. A method of dispensing a fluid, comprising: providing a flexible container having an interior fluid storage region therein and an opening extending from said interior fluid storage region to an exterior region outside the container;providing a volume of fluid within the interior fluid storage region;providing a flexible metering housing in the opening of the flexible container, having a metering chamber therein with a predetermined volume, disposed in fluid communication with the fluid storage region via the opening;providing a first valve disposed between the container and the flexible metering housing to permit unidirectional fluid flow from the interior fluid storage region of the container into the metering chamber;providing an exit port in fluid communication with the metering chamber with a second valve disposed between the exit port and the metering chamber;providing a spray member in fluid communication with the exit port;depressing the flexible metering housing;releasing the flexible metering housing;filling the metering chamber with a volume of fluid by vacuum force in an amount substantially the same as the volume of the metering chamber;depressing the flexible metering housing again; andspraying the volume of fluid within the metering chamber through the exit port via the second valve and the spray member. 17. The method of claim 16, further comprising the step of: dispersing fluid that has exited through the spray member proximal to the exterior region of the container. 18. The method of claim 16, further comprising the step of: providing a fluid conduit connected at a first end to the exit port and at a second end to the spray member; and routing fluid from the exit port and out through the spray member. 19. The method of claim 18, wherein the fluid conduit is positioned through the interior fluid storage region of the container. 20. The method of claim 16, further comprising the step of: preventing the first valve from being blocked.
