Abstract

An aerosol-generating system is provided, including a nicotine source; a volatile delivery enhancing compound source, wherein a volatile delivery enhancing compound comprises an acid; and a heating means for heating one or both of the nicotine source and the volatile delivery enhancing compound source, wherein one or both of the nicotine source and the volatile delivery enhancing compound source is encapsulated in a cylindrical polymeric capsule, and the cylindrical polymeric capsule includes a thermally conductive material.

First claim

1 . An aerosol-generating system comprising:
a nicotine source; a volatile delivery enhancing compound source, wherein the volatile delivery enhancing compound comprises an acid; and a heating means for heating one or both of the nicotine source and the volatile delivery enhancing compound source, wherein one or both of the nicotine source and the volatile delivery enhancing compound source is encapsulated in a cylindrical polymeric capsule comprising a thermally conductive material.

2 . An aerosol-generating system according to claim 1 wherein the thermally conductive material has a thermal conductivity of at least about 10 W/(m·K).

3 . An aerosol-generating system according to claim 1 or 2 wherein the thermally conductive material is included in one or more walls of the cylindrical polymeric capsule.

4 . An aerosol-generating system according to any one of claims 1 to 3 wherein the thermally conductive material is included in a polymeric coating provided on at least part of the interior surface of the cylindrical polymeric capsule.

5 . An aerosol-generating system according to claim 1 wherein the thermally conductive material is substantially homogenously distributed within the capsule.

6 . An aerosol-generating system according to any one of claims 1 to 5 wherein the nicotine source is encapsulated in a cylindrical polymeric capsule.

7 . An aerosol-generating system according to claim 6 wherein the interior of the cylindrical polymeric capsule in which the nicotine source is encapsulated is coated with one or more nicotine-resistant polymeric materials.

8 . An aerosol-generating system according to any one of claims 1 to 7 wherein the volatile delivery enhancing compound source is encapsulated in a cylindrical polymeric capsule.

9 . An aerosol-generating system according to claim 8 wherein the interior of the cylindrical polymeric capsule in which the volatile delivery enhancing compound source is encapsulated is coated with one or more volatile delivery enhancing compound-resistant polymeric materials.

10 . An aerosol-generating system according to any one of claims 1 to 9 further comprising:
a piercing member for piercing the cylindrical polymeric capsule.

11 . An aerosol-generating system according to claim 10 wherein the cylindrical polymeric capsule comprises one or more regions of reduced strength to facilitate piercing of the cylindrical polymeric capsule by the piercing member.

12 . An aerosol-generating system according to claim 11 wherein the one or more regions of reduced strength are formed by laser etching.

13 . An aerosol-generating system according to any one of claims 1 to 12 comprising:
an aerosol-generating article comprising the nicotine source and the volatile delivery enhancing compound source; and
an aerosol-generating device configured to receive the nicotine source and the volatile delivery enhancing compound source of the aerosol-generating article, wherein the aerosol-generating device comprises heating means for heating one or both of the nicotine source and the volatile delivery enhancing compound source of the aerosol-generating article.

14 . An aerosol-generating system according to claim 13 wherein the aerosol-generating device comprises a piercing member for piercing the cylindrical polymeric capsule.

15 . An aerosol-generating article for use in an aerosol-generating system according to claim 13 or 14 .

16 . Use of a cylindrical polymeric capsule comprising a thermally conductive material in an aerosol-generating system for generating a nicotine-containing aerosol comprising a heating means.
