Abstract

There is provided a smoking article having a mouth end and a distal end, the smoking article including a heat source positioned at the distal end; an aerosol-forming substrate adjacent to the heat source; and a cap configured to at least partially cover the heat source. The cap is attached at a line of weakness to the distal end, including a cylindrical plug of material circumscribed by a wrapper, and is removable to expose the heat source prior to use of the smoking article.

First claim

The invention claimed is:

1. A smoking article having a mouth end and a distal end, the smoking article comprising:
a combustible carbonaceous heat source disposed at the distal end and comprising carbon and at least one binder;
an aerosol-forming substrate adjacent to the heat source, disposed between the heat source and the mouth end inside of an outer wrapper circumscribing the smoking article; and
a removable cap disposed upstream of and directly adjacent to the heat source, the removable cap at the distal end of the smoking article and at least partially covering the heat source, the removable cap comprising a cylindrical plug of material and circumscribed by another wrapper extending longitudinally along the article, the another wrapper partially overlaying a rear portion of the heat source adjacent to the aerosol-forming substrate and being connected to the outer wrapper at a line of weakness circumscribing the article, wherein upon removal, only the heat source is exposed at the distal end of the smoking article.

2. The smoking article according to claim 1 , wherein the another wrapper further circumscribes at least a further portion of the smoking article, and wherein the line of weakness is provided in said another wrapper.

3. The smoking article according to claim 2 , wherein the another wrapper is affixed to the removable cap and at least a further portion of smoking article, remote from the line of weakness.

4. The smoking article according to claim 1 , wherein the removable cap is compressible along at least the transverse axis of the smoking article.

5. The smoking article according to claim 1 , wherein the line of weakness comprises a plurality of perforations which circumscribe the smoking article.

6. The smoking article according to claim 1 , wherein the removable cap comprises a desiccant.

7. The smoking article according claim 1 , wherein the removable cap has substantially the same diameter heat source.

8. The smoking article according to claim 1 , further comprising an elongate segment downstream of the aerosol-forming substrate, wherein the removable cap is made from the same material as the elongate segment.

9. The smoking article according to claim 1 , wherein the aerosol-forming substrate is downstream of the heat source.

10. The smoking article according to claim 1 , wherein the removable cap comprises visible indicia.

11. The smoking article according to claim 1 , wherein the line of weakness circumscribes at least a portion of the smoking article and the another wrapper comprises at least one longitudinal line of weakness.

12. The smoking article according to claim 11 , wherein the at least one longitudinal line of weakness extends from adjacent to the distal end towards the mouth end.

13. The smoking article according to claim 11 , wherein the at least one longitudinal line of weakness intersects or merges with the line of weakness.

14. The smoking article according to claim 11 , wherein the at least one longitudinal line of weakness has a length of from about 3 mm to about 13 mm.
