Aerosol-generating article comprising a detachable freshener delivery element with high ventilation

1. An aerosol-generating article comprising an aerosol-generating substrate and a mouthpiece secured to a downstream end of the aerosol-generating substrate, the mouthpiece comprising:

at least one segment of filter material; and

a vented segment downstream of the at least one segment of filter material and comprising at least one freshener delivery element;

wherein the vented segment comprising the at least one freshener delivery element is detachable from the at least one segment of filter material to decrease ventilation of the aerosol-generating article,

wherein the vented segment is at a downstream end of the mouthpiece, and

wherein detachment of the vented segment results in an increase in resistance to draw of the aerosol generating article.

2. An aerosol-generating article according to claim 1 , wherein the ventilation of the aerosol-generating article is at least 90 percent when the vented segment is attached to the at least one segment of filter material.

3. An aerosol-generating article according to claim 1 , wherein the ventilation of the aerosol-generating article is less than 90 percent after the vented segment has been detached from the at least one segment of filter material.

4. An aerosol-generating article according to claim 1 , further comprising a wrapper circumscribing the mouthpiece and a portion of the downstream end of the aerosol-generating substrate, the wrapper comprising at least one ventilation hole for admitting ambient air through the wrapper and into the vented segment.

5. An aerosol-generating article according to claim 4 , wherein the wrapper comprises a line of weakness along which the vented segment is detachable from the at least one segment of filter material.

6. An aerosol-generating article according to claim 5 , wherein the at least one ventilation hole comprises a line of ventilation holes, and wherein the line of ventilation holes forms the line of weakness.

7. An aerosol-generating article according to claim 5 , wherein the line of weakness overlies an upstream edge of the vented segment.

8. An aerosol-generating article according to claim 5 , wherein the line of weakness overlies the vented segment downstream of an upstream edge of the vented segment, and wherein a portion of the wrapper upstream of the line of weakness extends downstream of a downstream edge of the at least one segment of filter material so that the portion of the wrapper upstream of the line of weakness defines a mouth end recess when the vented segment has been detached.

9. An aerosol-generating article according to claim 1 , wherein the vented segment comprises a segment of support material in which the freshener delivery element is provided.

10. An aerosol-generating article according to claim 9 , wherein the segment of support material comprises one or more ventilation channels formed in a surface of the segment of support material.

11. An aerosol-generating article according to claim 9 , wherein the segment of support material has an annular shape defining a channel extending through at least part of the segment of support material between an upstream end of the segment of support material and a downstream end of the segment of support material, and wherein the at least one freshener delivery element is contained within the channel extending through at least part of the segment of support material.

12. An aerosol-generating article according to claim 11 , wherein each of the channel and the freshener delivery element has a substantially circular cross-sectional shape, and wherein an internal diameter of the channel is less than an external diameter of the freshener delivery element.

13. An aerosol-generating article according to claim 1 , wherein the at least one freshener delivery element comprises at least one solid freshener delivery element.

14. An aerosol-generating article according to claim 1 wherein the at least one freshener delivery element comprises at least one breakable capsule containing a gel or liquid freshener.

15. An aerosol-generating article according to claim 1 , wherein the at least one freshener delivery element comprises a flavourant comprising at least one of menthol, linalool, thymol, eucalyptol, methyl salicylate, and combinations thereof.
