Abstract

A refill for holding at least two compositions comprises a container including a body and first and second compositions disposed within the body such that the first and second compositions are substantially separated and the second composition is disposed above the first composition. The refill further includes a tube disposed within the body of the container such that the tube contains the first and second compositions, wherein the tube has an inner diameter and an outer diameter. Still further, the refill includes a wick disposed within the tube, wherein the wick contains the first and second compositions and has a diameter that is smaller than the inner diameter of the tube to create a gap between the wick and the tube.

First claim

We claim:

1. A method of emitting two or more compositions, the method including the steps of:
providing a refill including a container having a body and first and second compositions disposed within the body within a single reservoir, such that the first and second compositions are substantially separated within the single reservoir;
emitting a first portion of the second composition;
emitting a portion of the first composition after the first portion of the second composition is emitted; and
emitting a second portion of the second composition.

2. The method of claim 1 , wherein the step of emitting a portion of the first composition includes emitting substantially all of the first composition.

3. The method of claim 1 , wherein the step of emitting a second portion of the second composition includes emitting the second composition until substantially all of the second compositions is depleted.

4. The method of claim 1 , wherein the first portion of the second composition is emitted from within a tube, a portion of the first composition is emitted from within the tube and a remainder of the first composition is emitted from within the container, and the second portion of the second composition is emitted from within the container.

5. The method of claim 1 , further including the step of providing a dispenser including a housing forming a chamber adapted to retain the refill containing two or more compositions and a heater disposed within the chamber.

6. The method of claim 1 , wherein the second composition is disposed above and substantially separated from the first composition.

7. The method of claim 6 , wherein after the step of emitting a second portion of the second composition, the first composition is again emitted and emission of the first and second compositions repeats.

8. The method of claim 1 , wherein the second composition is disposed below and substantially separated from the first composition.

9. The method of claim 8 , wherein after the step of emitting a second portion of the second composition, the first composition is again emitted and emission of the first and second compositions repeats.

10. A method of emitting two or more compositions, the method including the steps of:
providing a refill including a container having a body and first and second compositions disposed within the body such that the first and second compositions are substantially separated;
emitting a first portion of the second composition with a wick;
emitting a portion of the first composition with the wick after the first portion of the second composition is emitted; and
emitting a second portion of the second composition with the wick.

11. The method of claim 10 , wherein the first and second compositions are disposed within a single reservoir within the container.

12. The method of claim 10 , wherein the wick is disposed at least partially within a tube, with the tube extending into both of the first and second compositions within the container.

13. The method of claim 12 , wherein the wick is at least partially spaced apart from an interior wall of the tube to provide one or more channels within the tube for flow of the first and second compositions around the wick.

14. The method of claim 12 , wherein the tube is a first tube;
wherein the wick is also disposed at least partially within a second tube, with the second tube disposed at least partially within the first tube so that at least a portion of the wick is disposed within both of the first and second tubes; and
wherein the method further includes the step of controlling the emission of at least one of the first and second compositions by rotating one of the first and second tubes relative to the other of the first and second tubes.

15. A method of emitting two or more compositions, the method including the steps of:
providing a refill including a container having a body, a tube, and first and second compositions disposed within the body within a single reservoir, such that the first and second compositions are substantially separated within the single reservoir and the tube extends into both of the first and second compositions within the single reservoir;
emitting a first portion of the second composition from the container with a wick that is disposed at least partially within the tube; and
emitting a portion of the first composition, with the wick, after the first portion of the second composition is emitted.

16. The method of claim 15 , wherein the wick is at least partially spaced apart from an interior wall of the tube to provide one or more channels within the tube for flow of the first and second compositions around the wick.

17. The method of claim 15 , wherein the tube is a first tube;
wherein the wick is also disposed at least partially within a second tube, with the second tube disposed at least partially within the first tube; and
wherein the method further includes the step of controlling the emission of at least one of the first and second compositions by rotating one of the first and second tubes relative to the other of the first and second tubes.

18. The method of claim 17 , wherein the first tube includes a first opening and the second tube includes a second opening; and
wherein rotating the one of the first and second tubes relative to the other of the first and second tubes at least one of opens, partially opens, closes, and partially closes at least one of the first opening and the second opening to control the emission of the at least one of the first and second compositions.

19. The method of claim 1 , wherein each of the steps of emitting the first portion of the second composition, emitting the portion of the first composition, and emitting the second portion of the second composition uses a shared wick.

20. The method of claim 19 , wherein the shared wick is disposed at least partially within a tube;
wherein the tube extends into both of the first and second compositions; and
wherein the first and second compositions are substantially separated within the tube.
