Abstract:
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.
