Abstract

An aerosol generating article comprises an aerosol generating material part and an inductively heatable susceptor positioned in a shell. The aerosol generating material part comprises at least ten aerosol generating strips substantially oriented in a first direction and the inductively heatable susceptor is positioned between the aerosol generating strips and comprises an elongate part which is substantially oriented in the first direction. Methods for manufacturing the aerosol generating article are also described.

First claim

The invention claimed is:

1. An aerosol generating article comprising:
a shell;
a filter; and
an aerosol generating material part and an inductively heatable susceptor positioned in the shell, wherein:
the aerosol generating material part comprises at least ten aerosol generating strips substantially oriented in a first direction, the aerosol generating material part having a density of the at least ten aerosol generating strips that is substantially uniform along the first direction; and
the inductively heatable susceptor is positioned between the aerosol generating strips, and comprises an elongate part which is substantially oriented in the first direction.

2. The aerosol generating article according to claim 1 , wherein the inductively heatable susceptor is strip-shaped and substantially oriented in the first direction.

3. The aerosol generating article according to claim 1 , wherein the aerosol generating material part is rod-shaped, the shell comprises a substantially tubular wrapper, and the rod-shaped aerosol generating material part and the inductively heatable susceptor are enclosed by the substantially tubular wrapper.

4. The aerosol generating article according to claim 3 , wherein at least some of the aerosol generating strips have a length which is less than the length of the tubular wrapper.

5. The aerosol generating article according to claim 1 , wherein the aerosol generating article comprises at least two strip-shaped inductively heatable susceptors.

6. The aerosol generating article according to claim 5 , wherein a major face of each of the at least two strip-shaped susceptors is substantially oriented in a second direction which is substantially orthogonal to the first direction.

7. The aerosol generating article according to claim 5 , wherein at least one of said aerosol generating strips is positioned between the at least two strip-shaped susceptors.

8. The aerosol generating article according to claim 5 , wherein the at least two strip-shaped susceptors are surrounded by the aerosol generating strips.

9. The aerosol generating article according to claim 1 , wherein the aerosol generating strips are foldless.

10. A method for continuously manufacturing the aerosol generating article according to claim 1 , comprising:
(i) supplying at least ten aerosol generating strips to a wrapping station;
(ii) supplying the inductively heatable susceptor to the wrapping station; and
(iii) wrapping the aerosol generating strips and the inductively heatable susceptor to form a continuous rod.

11. The method according to claim 10 , wherein step (ii) comprises positioning the inductively heatable susceptor between the aerosol generating strips.

12. The method according to claim 10 , wherein step (i) comprises cutting an aerosol generating sheet to form the aerosol generating strips immediately prior to, or during, positioning an end of the aerosol generating strips in a substantially tubular wrapper formed in step (iii).

13. The method according to claim 10 , wherein step (ii) comprises holding the inductively heatable susceptor whilst positioning an end of the inductively heatable susceptor in a substantially tubular wrapper formed in step (iii).

14. The method according to claim 10 , wherein step (ii) comprises supplying at least two strip-shaped susceptors to the wrapping station; and either:
(a) each of the at least two strip-shaped susceptors is supplied by a different feed unit; or
(b) each of the at least two strip-shaped susceptors is supplied by a common feed unit.

15. The method according to claim 10 , further comprising detecting, after step (iii), the position of the inductively heatable susceptor within the cross-sectional envelope of the continuous rod.

16. The method according to claim 15 , further comprising ceasing manufacture and/or adjusting one or more susceptor feed units based on the detected position to obtain a desired position of the inductively heatable susceptor within the cross-sectional envelope of the continuous rod.

17. An aerosol generating article comprising:
a shell;
a filter; and
an aerosol generating material part and an inductively heatable susceptor positioned in the shell, wherein:
the aerosol generating material part comprises at least ten aerosol generating strips substantially oriented in a first direction; and
the inductively heatable susceptor is positioned between the aerosol generating strips, and comprises an elongate part which is substantially oriented in the first direction,
wherein an end of the shell encloses the inductively heatable susceptor and the at least ten aerosol generating strips.

18. The aerosol generating article according to claim 17 , wherein the end of the shell includes a plurality of holes, so as to allow airflow.

19. The aerosol generating article according to claim 17 , further comprising
a paper wrapper coupling the filter to the shell.

20. The aerosol generating article according to claim 19 , wherein the inductively heatable susceptor is a U-shape or I-shape.
