SMOKING SUBSTITUTE CONSUMABLE
The present disclosure relates to aerosol-forming articles, including an aerosol-forming article comprising an aerosol-forming substrate wherein the aerosol-forming substrate comprises a pre-formed axially-extending recess adapted to receive an external heating element. The disclosure further relates to smoking substitute articles, including HNB consumables, which may comprise a cooling element formed of, for example, plant material.
1 . An aerosol-forming article comprising an aerosol-forming substrate wherein the aerosol-forming substrate comprises a pre-formed axially-extending recess adapted to receive an external heating element.
2 . An article according to claim 1 wherein the article is a heat not burn consumable.
3 . An article according to claim 1 wherein the axially-extending recess has an upstream axial end and a downstream axial end wherein the downstream axial end of spaced from the downstream axial end of the substrate.
4 . An article according to claim 3 wherein the axial spacing between the upstream and downstream axial ends of the axially-extending recess is between 1 and 7 mm.
5 . An article according to claim 1 wherein the axially-extending recess has a substantially circular radial cross-section at its upstream axial end with a diameter of between 1 and 3 mm.
6 . An article according to claim 1 wherein the axially-extending recess has a substantially uniform radial cross-sectional area along its axial length.
7 . An article according to claim 1 wherein the axially-extending recess tapers to a reduced cross-sectional area/diameter at a downstream axial end.
8 . An article according to claim 1 further comprising a filter element downstream and axially adjacent the aerosol-forming substrate.
9 . An article according to claim 8 further comprising a terminal mouth filter element at the axial downstream end of the article.
10 . An article according to claim 9 wherein the filter element and terminal filter element are axially spaced by a cooling element or spacer.
11 . An article according to claim 8 wherein the filter element and/or the terminal filter element is/are a hollow bore element.
12 . A smoking substitute system comprising an article according to claim 1 and a device comprising an elongated heating element.
13 . A method of using the system according to claim 12 , the method comprising:
inserting the article into the device such that the heating element is received in the axially extending recess; and
heating the article using the heating element.
