Also described is a non-combustible aerosol generating system comprising the article. a method of manufacturing the article. a heating element for use in a non-combustible aerosol provision system, and a non-combustible aerosol provision system comprising the heating element.

First claim

1 . An article for use in a non-combustible aerosol provision system, the article comprising:
an aerosol generating material; a heating element for heating the aerosol generating material; and an electrical connector arrangement for releasably connecting the heating element to an electrical power source.

2 . An article according to claim 1 , wherein the heating element is at least partly located within the aerosol generating material.

3 . An article according to claim 2 , wherein the electrical connector forms part of, or is in physical contact with, the heating element.

4 . An article according to claim 3 , wherein the electrical connector protrudes from, or is provided flush with, an external surface of the article.

5 . An article according to claim 4 , wherein the article comprises a mouth and an aerosol generating end, and wherein the electrical connector protrudes from an upstream end of the aerosol generating material.

6 . An article according to claim 1 wherein the connector is at least one of a bayonet-type connector and a screw-type connector.

7 . An article according to claim 4 wherein the electrical connector protrudes from an upstream end of the aerosol generating material and forms the upstream most end of the article.

8 . An article according to claim 1 , wherein the electrical connector comprises first and second terminal portions for connecting to respective first and second terminal portions of the electrical power source.

9 . An article according to claim 1 , wherein the electrical connector and heating element together form a pin inserted in the aerosol generating material, wherein the heating element is a first pin portion of the pin extending along a length of the aerosol generating material, and the electrical connector is a second pin portion being connected to the first pin portion and extending substantially perpendicularly to the length of the article.

10 . An article according to claim 9 , wherein the second pin portion covers the external surface of the upstream most end of the aerosol generating material to thereby form a cap at the upstream most end of the article.

11 . An article according to claim 1 , wherein the heating element is a wire element extending through the aerosol generating material, the wire element forming at least one loop, and the electrical connector comprises first and second ends of the heating element, first and second ends extending at least to the upstream most end of the aerosol generating material such that first and second ends are physically contactable by the electrical power source.

12 . An article according to claim 11 , wherein the wire element is looped in a helical arrangement.

13 . An article according to claims 11 , wherein the first and second ends comprise respective first and second plates extending substantially perpendicularly to the length of the article, first and second ends being configured to extend along an external end of the aerosol generating material for being physically contacted by the electrical power source.

14 . An article according to claim 1 , wherein the electrical connector comprises a magnetic material configured to magnetically couple to an electromagnet forming part of the electrical power source.

15 . An article according to claim 1 , wherein the article comprises a mouth end section provided downstream of the aerosol generating material.

16 . An article according to claim 15 , wherein the mouth end section comprises at least one filter segment.

17 . An article according to claim 15 , wherein the mouth end section comprises a cooling section provided downstream of the aerosol generating material, the cooling section comprising a hollow channel.

18 . An article according to claim 15 , the mouth end section comprising a hollow tubular element forming the downstream most end of the article.

19 . A non-combustible aerosol generation system comprising:
an article according to any of claims 1 ; and an aerosol generating device configured comprising an electrical power source configured to contact the electrical connector to thereby transmit electrical power to the heating element of the article.

20 . A non-combustible aerosol generation system according to claim 19 , wherein the aerosol generating device comprises an electromagnet for magnetically coupling to a magnetic portion of the electrical connector when the electrical connector is in physical contact with the electrical power source.

21 . A non-combustible aerosol generation system according to claim 19 , wherein the electrical power source of the aerosol generating device comprises first and second electrical terminals for connecting to first and second terminals of the article.

22 . A method of manufacturing an article according to claim 1 comprising:
providing an aerosol generating material; and
inserting a heating element into the aerosol generating material; and
providing an electrical connector arrangement for releasably connecting the heating element to an electrical power source.

23 . A method according to claim 22 , further comprising:
extruding tobacco together with helical element, cutting the tobacco and helical element at a location at which helix threads are separated by a predetermined distance.

24 . A heating element for use in a non-combustible aerosol provision system, the heating element comprising an electrical connector arrangement for releasably connecting the heating element to an electrical power source.

25 . A heating element according to claim 24 , wherein the electrical connector arrangement comprises a threaded screw arrangement configured to releasably connect to a complementary receptor of the electrical power source.

26 . A heating element according to claim 24 , wherein the electrical connector arrangement comprises a bayonet connector arrangement configured to releasably connect to a complementary receptor of the electrical power source.

27 . A heating element according to claim 24 , wherein the electrical connector arrangement comprises a pogo pin arrangement configured to releasably connect to a complementary receptor of the electrical power source.

28 . A non-combustible aerosol provision system comprising:
the heating element of claim 24 ; an aerosol provision device comprising an electrical power source configured to electrically connect to the heating element; an article for use in the non-combustible aerosol provision system, the article comprising an aerosol generating material configured to receive the heating element.
