SUBSTITUTE SMOKING CONSUMABLE
The present disclosure relates to a heat not burn (HNB) consumable comprising an aerosol-forming substrate and a downstream filter having upper and lower surfaces spaced by opposing longitudinally-extending transverse surfaces wherein the filter has a greater width than depth. The filter may comprise at least one inwardly-extending air flow path extending from at least one of the upper, lower or transverse surfaces. At least one of the surfaces may be a curved or rounded surface or comprises a curved or rounded surface portion.
1 . A heat not burn (HNB) consumable comprising an aerosol-forming substrate and a downstream filter having upper and lower surfaces spaced by opposing longitudinally-extending transverse surfaces wherein the filter has a greater width than depth and wherein the filter comprises at least one inwardly-extending air flow path extending from at least one of the upper, lower or transverse surfaces towards an axial centre of the filter.
2 . A consumable according to claim 1 wherein the upper and lower surfaces of the filter are substantially planar and equally spaced by planar transverse surfaces such that the filter is a cuboid filter.
3 . A consumable according to claim 1 wherein at least one of the upper, lower and transverse surfaces is a curved or rounded surface or comprises a curved or rounded surface portion.
4 . (canceled)
5 . A consumable according to claim 3 wherein the filter has convex or concave opposing transverse surfaces.
6 . A consumable according to claim 5 wherein each transverse surface comprises longitudinally-extending upper and lower concave portions which meet at a longitudinally-extending ridge.
7 . A consumable according to claim 3 wherein one or both of the upper/lower surfaces is a convex rounded surface.
8 . A consumable according to claim 5 comprising at least one inwardly extending air flow path extending from at least one of the upper, lower and/or transverse surfaces into the filter.
9 . A consumable according to claim 1 comprising a plurality of inwardly-extending air flow paths.
10 . A consumable according to claim 9 wherein the plurality of air flow paths are equally spaced around the perimeter of the filter.
11 . A consumable according to claim 1 wherein the filter comprises a hollow bore.
12 - 15 . (canceled)
16 . A heat not burn (HNB) consumable comprising an aerosol-forming substrate and a downstream filter having upper and lower surfaces spaced by opposing longitudinally-extending transverse surfaces wherein at least one of the surfaces of the filter is a curved or rounded surface or comprises a curved or rounded surface portion and wherein the filter has a greater width than depth.
17 . A consumable according to claim 16 wherein the filter has convex or concave opposing transverse surfaces.
18 . A consumable according to claim 17 wherein each transverse surface comprises longitudinally-extending upper and lower concave portions which meet at a longitudinally-extending ridge.
19 . A consumable according to claim 16 wherein one or both of the upper/lower surfaces is a convex rounded surface.
20 . A consumable according to claim 16 comprising at least one inwardly extending air flow path extending from at least one of the upper, lower and/or transverse surfaces into the filter.
21 . A consumable according to claim 20 comprising a plurality of inwardly-extending air flow paths.
22 . A consumable according to claim 21 wherein the plurality of air flow paths are equally spaced around the perimeter of the filter.
23 . A consumable according to claim 16 wherein the filter comprises a hollow bore.
24 . A heat not burn (HNB) system comprising:
a heat not burn consumable according to claim 1 ; and
a device comprising at least one heating element.
25 . A heat not burn (HNB) system comprising:
a heat not burn consumable according to claim 16 ; and
