Abstract

The present disclosure relates to a cartridge for an aerosol delivery device, an aerosol delivery device that includes the cartridge, and an aerosol device operation method. In various implementations the cartridge comprises a reservoir tank configured to contain an aerosol precursor composition, a masking disc proximate the aerosol precursor composition, and a flavor disc proximate the masking disc. At least one of the masking disc or the flavor disc is configured to be rotated relative to the other to align an opening of the masking disc with a selected section of the flavor disc so as to allow the aerosol precursor composition to flow from the reservoir tank through the opening of the masking disc and the selected section of the flavor disc, such that, when the flavor section is selected, the flavorant is imparted to the aerosol precursor composition.

Claims

1. An aerosol delivery device, comprising:

a control body;

a cartridge, comprising;

a reservoir tank configured to contain an aerosol precursor composition;

a masking disc proximate the aerosol precursor composition, the masking disc including an opening configured to the permit aerosol precursor composition to pass therethrough; and

a flavor disc proximate the masking disc, the flavor disc including two or more separate sections, wherein at least two of the sections are configured to permit the aerosol precursor composition to pass therethrough, and at least one of the sections comprises a flavor section that contains a flavorant; and

an atomizer configured to receive the aerosol precursor composition and produce an aerosol,

wherein at least one of the masking disc or the flavor disc is configured to be rotated relative to the other to align the opening of the masking disc with a selected section of the flavor disc so as to allow the aerosol precursor composition to flow from the reservoir tank through the opening of the masking disc and the selected section of the flavor disc to the atomizer such that, when the flavor section is selected, the flavorant is imparted to the aerosol precursor composition delivered to the atomizer.

2. The aerosol delivery device of claim 1, wherein the flavor disc further comprises a solid section configured to block the flow of the aerosol precursor composition when the opening of the masking disc is aligned therewith.

3. The aerosol delivery device of claim 1, further comprising a cartridge base that includes two or more passageways, wherein each passageway is configured to align with a separate section of the flavor disc so as to facilitate flow of the aerosol precursor composition from the reservoir tank through the selected flavor disc section and to the atomizer.

4. The aerosol delivery device of claim 1, wherein the masking disc is affixed to the reservoir tank, and wherein the reservoir tank is configured to be rotated so as to rotate the masking disc to align the opening of the masking disc with a selected section of the flavor disc.

5. The aerosol delivery device of claim 1, wherein the reservoir tank comprises a housing that includes a liquid cavity defined therein, and wherein the liquid cavity is configured to contain the aerosol precursor composition.

6. The aerosol delivery device of claim 1, wherein the cartridge defines a mouth end and a connecting end, and wherein the connecting end includes a threaded portion configured to thread into an engaging end of the control body.

7. The aerosol delivery device of claim 1, wherein the flavor disc includes at least three separate sections, wherein one of the sections comprises a solid section, wherein at least two other sections comprise flavor sections, and wherein at least two of the flavor sections contain different flavorants.

8. The aerosol delivery device of claim 1, wherein the flavor disc includes nine separate sections, wherein one of the sections comprises a solid section, wherein the eight other sections comprise flavor sections, and wherein each of the flavor sections contains a different flavorant.

9. The aerosol delivery device of claim 8, further comprising a cartridge base that includes eight passageways, wherein each passageway is configured to align with a separate respective flavor section of the flavor disc so as to facilitate flow of the aerosol precursor composition from the reservoir tank through a selected flavor section and to the atomizer.

10. The aerosol delivery device of claim 1, wherein the flavor section of the flavor disc comprises an outer shell defining an inner surface that surrounds an inner chamber, wherein the outer shell comprises a porous material that contains the flavorant, and wherein the inner chamber is configured to allow the aerosol precursor composition to flow therethrough against the inner surface.

11. A cartridge for use in an aerosol delivery device, comprising:

a reservoir tank configured to contain an aerosol precursor composition;

a masking disc proximate the aerosol precursor composition, the masking disc including an opening configured to the permit aerosol precursor composition to pass therethrough; and

a flavor disc proximate the masking disc, the flavor disc including two or more separate sections, wherein at least two of the sections are configured to permit the aerosol precursor composition to pass therethrough, and at least one of the sections comprises a flavor section that contains a flavorant, and

wherein at least one of the masking disc or the flavor disc is configured to be rotated relative to the other to align the opening of the masking disc with a selected section of the flavor disc so as to allow the aerosol precursor composition to flow from the reservoir tank through the opening of the masking disc and the selected section of the flavor disc, such that, when the flavor section is selected, a flavor from the flavorant is imparted to the aerosol precursor composition.

12. The cartridge of claim 11, wherein the flavor disc further comprises a solid section configured to block the flow of the aerosol precursor composition when then opening of the masking disc is aligned therewith.

13. The cartridge of claim 11, further comprising a cartridge base that includes two or more passageways, wherein each passageway is configured to align with a separate section of the flavor disc so as to facilitate flow of the aerosol precursor composition from the reservoir tank through the selected flavor disc section.

14. The cartridge of claim 11, wherein the masking disc is affixed to the reservoir tank, and wherein the reservoir tank is configured to be rotated so as to rotate the masking disc to align the opening of the masking disc with a selected section of the flavor disc.

15. The cartridge of claim 11, wherein the reservoir tank comprises a housing that includes a liquid cavity defined therein, and wherein the liquid cavity is configured to contain the aerosol precursor composition.

16. The cartridge of claim 11, further comprising a mouth end and a connecting end, and wherein the connecting end includes a threaded portion.

17. The cartridge of claim 11, wherein the flavor disc includes at least three separate sections, wherein one of the sections comprises a solid section, wherein at least two other sections comprise flavor sections, and wherein at least two of the flavor sections contain different flavorants.

18. The cartridge of claim 11, wherein the flavor disc includes nine separate sections, wherein one of the sections comprises a solid section, wherein the eight other sections comprise flavor sections, and wherein each of the flavor sections contains a different flavorant.

19. The cartridge of claim 17, further comprising a cartridge base that includes eight passageways, wherein each passageway is configured to align with a separate respective flavor section of the flavor disc so as to facilitate flow of the aerosol precursor composition from the reservoir tank through a selected flavor section.

20. The cartridge of claim 11, wherein the flavor section of the flavor disc comprises an outer shell defining an inner surface that surrounds an inner chamber, wherein the outer shell comprises a porous material that contains the flavorant, and wherein the inner chamber is configured to allow the aerosol precursor composition to flow therethrough against the inner surface.
