Patent ID: 8123073

Claim:
A method of dispensing a fluid, comprising: providing a container made from flexible material and having an outer surface, a first opening and an interior fluid storage region therein; providing a volume of fluid within the interior fluid storage region; providing a flexible metering housing extending outwardly from the first opening of the container, the flexible metering housing having a bottom periphery sealed about the interior fluid storage region of the first opening, the metering housing further having a metering chamber therein with a predetermined volume, disposed in fluid communication with the interior fluid storage region; providing an intake valve disposed between the container and the flexible metering housing permitting 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 container with an output valve disposed between the exit port and the metering chamber; 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 by the volume of the metering chamber; depressing the flexible metering housing again; urging the volume of fluid within the metering chamber through the exit port via the output valve; and collapsing the container with the unidirectional flow of the intake valve as fluid is evacuated from within the container; wherein the metering chamber is filled with the fluid regardless of an orientation of the container with respect to gravity; and wherein the fluid is dispensed regardless of the orientation of the container with respect to gravity.
