METERING DISPENSING FLEXIBLE POUCH WITH SPRAY NOZZLE
First Claim
1. A fluid dispensing device, comprising:
- a 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;
a flexible metering housing, 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;
the flexible metering housing further including a metering housing output port;
a second valve, having a second valve output port, in fluid communication with the metering housing output port 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;
a spray applicator in fluid communication with the second valve output port to deliver liquid in a metered fashion in a spray form.

Abstract
An atomizing fluid dispenser for delivering, via a spray nozzle, a substantially equal metered dose of fluid material for each dispensing operation is disclosed. 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.

16. A method of dispensing a fluid, comprising:
-
providing a 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, having a metering chamber therein with a predetermined volume, disposed in fluid communication with the fluid storage chamber 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 output 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 output 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; and spraying the volume of fluid within the metering chamber through the exit port via the second valve and the spray member. - View Dependent Claims (17, 18, 19, 20)
