Abstract

A dispensing device is provided that includes at least two separate reservoirs therein and a dispenser for mixing and delivering a substantially equal metered dose of fluid material from the reservoirs with each dispensing operation. In one example, the present invention relates to a dispenser for mixing and delivering hair colorant that allows the user to dispense a metered dose of the hair colorant components in a manner that measures and mixes those components with each dispensing operation. An optional applicator may be provided for even distribution of the dispensed hair colorant material.

Claims

1. A fluid dispensing device, comprising:

at least one first fluid reservoir containing a first fluid;

a first metered dispensing pump for outputting a measured amount of first fluid from the first fluid reservoir;

at least one second fluid reservoir containing a second fluid;

a second metered dispensing pump for outputting a measured amount of second fluid from the second fluid reservoir;

a mixing chamber to receive and mix the output of the first and second metered dispensing pumps;

an exit aperture through which mixed first and second fluids are delivered.

2. The fluid dispensing device of claim 1, wherein the first and second metered dispensing pumps have parallel outputs that dispense onto the mixing chamber.

3. The fluid dispensing device of claim 1, the first and second metered dispensing pumps each comprising:

a flexible metering housing, having a metering chamber therein with a predetermined volume, disposed in fluid communication with the first and second fluid reservoirs;

a first valve disposed between the first and second fluid reservoirs and the flexible metering housing to permit unidirectional fluid flow from the first and second fluid reservoirs 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.

4. The fluid dispensing device of claim 1, wherein the exit aperture directs the mixed first and second fluid into an applicator.

5. The fluid dispensing device of claim 1, wherein the first and second metered dispensing pumps are positioned adjacent one another such that a user depresses them simultaneously.

6. The fluid dispensing device of claim 1, wherein the first and second fluids are first and second parts of a hair colorant system.

7. The fluid dispensing device of claim 1, wherein the first and second fluids are first and second parts of a hair conditioning system.

8. A fluid dispensing device, comprising:

at least one first fluid reservoir containing a first fluid;

a first metered dispensing pump for outputting a measured amount of first fluid from the first fluid reservoir;

at least one second fluid reservoir containing a second fluid;

a second metered dispensing pump for receiving the first fluid output and mixing the first fluid output with a measured amount of second fluid from the second fluid reservoir;

an exit aperture through which mixed first and second fluids are delivered.

9. The fluid dispensing device of claim 8, wherein the first and second metered dispensing pumps are arranged to dispense in a serial fashion.

10. The fluid dispensing device of claim 8, wherein a volume of the second metered dispensing pump is larger than a volume of the first metered dispensing pump.

11. The fluid dispensing device of claim 8, the first and second metered dispensing pumps each comprising:

a flexible metering housing, having a metering chamber therein with a predetermined volume, disposed in fluid communication with the first and second fluid reservoirs;

a first valve disposed between the first and second fluid reservoirs and the flexible metering housing to permit unidirectional fluid flow from the first and second fluid reservoirs 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 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.

12. The fluid dispensing device of claim 11, wherein a volume of the second metered dispensing pump is larger than a volume of the first metered dispensing pump.

13. The fluid dispensing device of claim 8, wherein the exit aperture directs the mixed first and second fluid into an applicator.

14. The fluid dispensing device of claim 8, wherein the first and second metered dispensing pumps are positioned adjacent one another such that a user depresses them simultaneously.

15. The fluid dispensing device of claim 8, wherein the first and second fluids are first and second parts of a hair colorant system.

16. The fluid dispensing device of claim 8, wherein the first and second fluids are first and second parts of a hair conditioning system.

17. The fluid dispensing device of claim 8, wherein a volume of the second metered dispensing pump is larger than a volume of the first metered dispensing pump.
