DISPENSER WITH DUAL PUMP SYSTEM
First Claim
1. A fluid dispensing device, comprising:
- a plurality of fluid reservoirs each containing a fluid;
a plurality of metered dispensing pumps wherein one of the plurality of dispensing pumps in is fluid communication with one of each of the plurality of fluid reservoirs, the dispensing pumps configured and arranged for outputting a measured amount of fluid from its respective fluid reservoir; and
an exit aperture through which the plurality of metered dispensing pumps delivers the output fluid.

Abstract
A fluid dispenser is provided that includes a multiple chamber fluid storage region, each having a dispensing pump of its own such that the dispenser can dispense the fluids from within the multiple fluid storage regions. Further, the multiple fluid storage regions may each contain the same or different liquids. The dispensing pumps include a metering housing, which when depressed, generate 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 each of the fluids is dispensed from the container, while upon release, the metering housings are refilled by drawing fluids from their respective fluid storage regions. The fluids are mixed in the exit port as they are dispensed from the metering pumps.

2. The fluid dispensing device of clam 1, the metered dispensing pumps each comprising:
-
a flexible metering housing, having a metering chamber therein with a predetermined volume, disposed in fluid communication with the associated fluid reservoir; a first valve disposed between the associated fluid reservoir and the flexible metering housing to permit unidirectional fluid flow from the associated fluid reservoir into the metering chamber thereby filling the predetermined volume of the metering chamber, the flexible metering housing further including a metering housing output port; and a second valve, having a second valve output port, in fluid communication with the mixing chamber and permitting unidirectional fluid flow of a volume of fluid substantially equal to the predetermined volume of the metering chamber from the metering chamber via the second valve output port.
