Abstract

An e-vaping device having a cartridge including an outer container extending in a longitudinal direction, a conduit within the outer container, a storage portion including pre-vapor formulation ingredients, the storage portion being between the outer container and the conduit and including a plurality of chambers, a plurality of wicks, each of the wicks being in communication with each of the chambers and the conduit and being configured to deliver one or more ingredients in each of the chambers to the conduit, and a coil heater located in the chimney and operatively coupled to each of the wicks. The e-vaping device also includes a power supply source coupled to the cartridge, the power supply source is configured to heat the wicks to vaporize ingredients located in respective chambers and generate a vapor corresponding to each of the vaporized ingredients.

Claims (37)

1. A cartridge of an e-vaping device, comprising:

an outer container extending in a longitudinal direction;

a conduit within the outer container;

a storage portion between the outer container and the conduit, the storage portion being configured to store pre-vapor formulation ingredients, and including a plurality of chambers;

a plurality of wicks, each of the wicks being in fluid communication with at least one of the plurality of chambers and the conduit and being configured to deliver one or more ingredients in each of the plurality of chambers to the conduit;

a heater operatively coupled to one or more of the plurality of wicks.

2. The cartridge of claim 1 , wherein two adjacent chambers of the plurality of chambers are separated by one or more separators.

3. The cartridge of claim 2 , wherein the one or more separators are configured to substantially inhibit first pre-vapor formulation ingredients in a first chamber of the plurality of chambers from mixing with second pre-vapor formulation ingredients in a second chamber of the plurality of chambers.

4. The cartridge of claim 1 , wherein one or more of the pre-vapor formulation ingredients are in gel form.

5. The cartridge of claim 1 , wherein the plurality of chambers include one of two chambers, three chambers, four chambers, five chambers and six chambers.

6. The cartridge of claim 1 , wherein the conduit is a chimney.

7. The cartridge of claim 1 , wherein the heater is intertwined with one or more of the plurality of wicks.

8. The cartridge of claim 1 , wherein at least one of the chambers is configured to store at least one of the pre-vapor formulation ingredients and at least another of the chambers is configured to store at least another of the pre-vapor formulation ingredients.

9. The cartridge of claim 8 , wherein one of the chambers is configured to store nicotine and another of the chambers is configured to store one or more acids.

10. The cartridge of claim 8 , wherein one of the chambers is configured to store one or more flavorants and another of the chambers is configured to store one or more acids.

11. An e-vaping device, comprising:

a cartridge including:

an outer container extending in a longitudinal direction;

a conduit within the outer container;

a storage portion between the outer container and the conduit, the storage portion being configured to store pre-vapor formulation ingredients, and including a plurality of chambers;

a plurality of wicks, each of the wicks being in fluid communication with at least one of the plurality of chambers and the conduit and being configured to deliver one or more ingredients in each of the plurality of chambers to the conduit; and

a heater operatively coupled to one or more of the plurality of wicks; and

a power supply source coupled to the cartridge, the power supply source being configured to power the heater to heat the pre-vapor formulation ingredients via the one or more of the plurality of wicks.

12. The e-vaping device of claim 11 , wherein a vapor resulting from the heating of the pre-vapor formulation ingredients and formed in the conduit is a mixture of vapors resulting from the heating of the ingredients stored in each of the plurality of chambers.

13. The e-vaping device of claim 11 , wherein the conduit is a chimney.

14. A method of operating an e-vaping device, the e-vaping device including an outer shell and an inner conduit, a storage portion between the outer shell and the inner conduit being configured to store ingredients of a pre-vapor formulation and including a plurality of chambers, and a mouth-end insert, the method comprising:

substantially separating each of the plurality of chambers from adjacent chambers via a separator;

storing one or more ingredients of the pre-vapor formulation in one or more of the plurality of chambers;

connecting one or more of the plurality of chambers with the inner conduit via a respective wick configured to deliver the one or more ingredients present in the one or more of the plurality of chambers to the inner conduit;

upon operation of the e-vaping device, vaporizing each of the ingredients delivered, from each of the one or more of the plurality of chambers, in the inner conduit to generate vaporized ingredients; and

expressing a combination of the vaporized ingredients through the mouth-end insert.

15. The method of claim 14 , wherein the substantially separating comprises substantially inhibiting first pre-vapor formulation ingredients in a first chamber from mixing with second pre-vapor formulation ingredients in a second chamber.

16. The method of claim 14 , wherein the storing comprises storing at least one ingredient of the pre-vapor formulation in at least one of the chambers and storing at least another ingredient of the pre-vapor formulation in at least another chamber.

17. The method of claim 16 , wherein the storing comprises storing nicotine in one of the chambers and storing one or more acids in another of the chambers.

18. The method of claim 16 , wherein the storing comprises storing one or more flavorants in one of the chambers and storing one or more acids in another of the chambers.

19. The cartridge of claim 1 , wherein the plurality of chambers are adjacent to each other in a plane perpendicular to the longitudinal direction of the cartridge.

20. The e-vaping device of claim 11 , wherein the plurality of chambers are adjacent to each other in a plane perpendicular to the longitudinal direction of the cartridge.
