The fluid dispensing device (10) includes a container (20) with an interior fluid storage region (22) therein. A flexible metering housing (26) is disposed in fluid communication with the fluid storage region (22) a first one-way valve (30) disposed between the container (20) and the flexible metering housing (26). One way flow from the interior fluid storage region (22) of the container (20) fills the predetermined volume of the metering chamber (32) with fluid by vacuum action when a button (36) is depressed and then released. A second valve (40) is in fluid communication with the metering housing (26) and permits one-way fluid flow from the metering chamber (32) to the exterior outer region of the container (20) when the metering housing (26) is depressed again. Each time the metering housing (26) is depressed a substantially equal volume of fluid (24) is dispensed from the container (20). An additional foam layer (12) on the outside of container (20) facilitates dispersion and delivery of the fluid (24).

What is claimed is: 1. A fluid dispensing device, comprising: a container having an outer surface and a first opening; the container defining an interior fluid storage region therein, and an exterior outer region; a flexible metering housing, having a metering chamber therein with a predetermined volume, disposed in fluid communication with the fluid storage region; an intake valve disposed between the container and the flexible metering housing and permitting 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; an output valve, in fluid communication with the metering housing and permitting unidirectional fluid flow from the metering chamber to the exterior outer region of the container of a volume of fluid substantially equal to the predetermined volume of the flexible metering housing; and wherein the container is made from a flexible material, and wherein the flexible material of the container and the unidirectional flow of the intake valve cause the container to collapse as fluid is evacuated from within the container such that the fluid dispensing device is gravity independent. 2. The fluid dispensing device of claim 1, further comprising: means for dispersing fluid about the exterior outer region of the container. 3. The fluid dispensing device of claim 2, wherein the container defines at least one notch therein. 4. The fluid dispensing device of claim 2, wherein the means for dispersing is at least one area of foam positioned about the container. 5. The fluid dispensing device of claim 2, wherein the means for dispersing is a layer of fabric positioned about the container. 6. The fluid dispensing device of claim 1, further comprising: a fluid conduit connected at one end to the output valve and at the other end to an exit port defined by the container. 7. The fluid dispensing device of claim 6, wherein the first opening and the exit port are on opposing sides of the container from one another. 8. The fluid dispensing device of claim 6, wherein the fluid conduit is routed through the interior fluid storage region of the container. 9. The fluid dispensing device of claim 6, further comprising: a plurality of fluid conduits connected to the output valve at one end and respectively to a plurality of exit ports defined by the container. 10. The fluid dispensing device of claim 1, further comprising: a fluid conduit disposed between the metering housing and the output valve. 11. The fluid dispensing device of claim 1, further comprising: a re-fill port connected to the container. 12. The fluid dispensing device of claim 1, further comprising a plurality of output valves. 13. The fluid dispensing device of claim 1, wherein the intake valve and the output valve are one-way check valves. 14. The fluid dispensing device of claim 1, further comprising a strap connected to the container. 15. The fluid dispensing device of claim 1 further comprising: standoff means connected to the metering housing and proximal to the intake valve to prevent the intake valve from being blocked. 16. The fluid dispensing device of claim 15, wherein the standoff means is at least one leg. 17. The fluid dispensing device of claim 15, wherein the standoff means is a spring. 18. The fluid dispensing device of claim 1, further comprising: a frame attached to the container; and applicator material attached to the frame. 19. The fluid dispensing device of claim 1, wherein the output valve is located at an exit port.
