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

1 . An aerosol generating article comprising:
a shell; 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.

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 one or both ends of each of the inductively heatable susceptor, the rod-shaped aerosol generating material part and the tubular wrapper are substantially aligned in the longitudinal direction.

5 . The aerosol generating article according to claim 3 , wherein the aerosol generating strips, the strip-shaped inductively heatable susceptor and the tubular wrapper are substantially the same length.

6 . 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.

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

8 . The aerosol generating article according to claim 7 , 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.

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

10 . The aerosol generating article according to claim 7 , wherein the at least two strip-shaped susceptors are surrounded by the aerosol generating strips.

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

12 . The aerosol generating article according to claim 1 , wherein the aerosol generating article is substantially cylindrical and includes a formation to facilitate circumferential positioning of the aerosol generating article in an aerosol generating device.

13 . 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.

14 . The method according to claim 13 , wherein step (ii) comprises positioning the inductively heatable susceptor between the aerosol generating strips.

15 . The method according to claim 13 , 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).

16 . The method according to claim 13 , 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).

17 . The method according to claim 13 , 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.

18 . The method according to claim 13 , further comprising detecting, after step (iii), the position of the inductively heatable susceptor within the cross-sectional envelope of the continuous rod.

19 . The method according to claim 18 , 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.
