Abstract

Embodiments of the disclosure relate to an article for use in a non-combustible aerosol provision system, the article comprising an aerosol generating material and a mouthpiece connected to the aerosol generating material, wherein the mouthpiece comprises a cavity having an internal volume greater than 450 mm3. There is also provided a system including the article and a non-combustible aerosol provision device for heating the aerosol generating material of the article.

First claim

1 . An article for use in a non-combustible aerosol provision system, the article comprising:
an aerosol generating material; and a mouthpiece connected to the aerosol generating material, wherein the mouthpiece comprises a cavity having an internal volume greater than 450 mm 3 .

2 . The article of claim 1 , wherein the cavity comprises an internal volume greater than 600 mm 3 .

3 . The article of claim 1 , wherein the mouthpiece comprises a body of material downstream from said cavity.

4 . The article of claim 3 , wherein the body of material comprises filamentary tow.

5 . The article of claim 4 , wherein the filamentary tow comprises a denier per filament of between 7 and 12.

6 . The article of claim 4 , wherein the filamentary tow comprises a total denier of between 10,000 and 25,000.

7 . The article of claim 4 ,
wherein the body of material is in the form of a cylinder having a longitudinal axis, the article further comprising a capsule embedded within the body of material such that the capsule is surrounded on all sides by the material forming the body, the capsule having a shell encapsulating a liquid aerosol modifying agent, and wherein the largest cross sectional area of the capsule measured perpendicularly to the longitudinal axis is less than 28% of the cross sectional area of the body of material measured perpendicularly to the longitudinal axis.

8 . The article of claim 1 ,
wherein the cavity is adjacent to said aerosol generating material.

9 . The article of claim 1 ,
wherein the mouthpiece comprises an upstream end adjacent to the aerosol generating material and a downstream end distal from the aerosol generating substrate, and a hollow tubular element formed from filamentary tow at the downstream end of the mouthpiece.

10 . The article of claim 9 , wherein the hollow tubular element comprises a minimum wall thickness of greater than 0.9 mm.

11 . The article of claim 9 , wherein the hollow tubular element comprises a density between 0.25 g/cc and 0.75 g/cc, or between 0.25 g/cc and 0.65 g/cc or between 0.35 g/cc and 0.65 g/cc.

12 . The article of claim 9 ,
wherein the hollow tubular element comprises an internal diameter of greater than 3.0 mm, or an internal diameter of greater than 3.5 mm.

13 . The article of claim 9 ,
wherein the hollow tubular element comprises a first hollow tubular element and wherein the mouthpiece comprises a second hollow tubular element upstream of the first hollow tubular element, the second hollow tubular element defining said cavity.

14 . The article of claim 1 ,
comprising an outer circumference of between 19 mm and 23 mm.

15 . The article of claim 1 ,
wherein the mouthpiece comprises a ventilation level of between 50% and 80% of aerosol drawn through the article.

16 . The article of claim 1 ,
wherein the article comprises a wrapper.

17 . The article of claim 16 , wherein the wrapper circumscribes the aerosol generating material.

18 . The article of claim 16 , wherein the wrapper has a permeability of less than 100 Coresta Units, less than 80 Coresta Units, less than 60 Coresta Units or less than 20 Coresta Units.

19 . The article of claim 16 , wherein the wrapper comprises a metallic layer.

20 . The article of claim 16 , wherein the wrapper comprises an aerosol modifying additive.

21 . The article of claim 1 ,
wherein the aerosol generating material comprises reconstituted tobacco material having a density of less than about 700 milligrams per cubic centimetre or reconstituted tobacco material having a density of less than about 600 milligrams per cubic centimetre.

22 . The article of claim 1 ,
wherein the aerosol generating material comprises a tobacco component, wherein the tobacco component comprises leaf tobacco in an amount of between about 10% and about 90% by weight of the tobacco component and wherein the leaf tobacco has a nicotine content of greater than 1.5% by weight of the leaf tobacco.

23 . The article of claim 22 , wherein the leaf tobacco comprises at least a portion of aerosol forming material in an amount of up to about 10% by weight of the leaf tobacco, and wherein the tobacco component comprises said aerosol forming material in an amount between about 10% and about 30% by weight of the tobacco component.

24 . The article of claim 1 ,
wherein the aerosol generating material comprises an aerosol forming material, and wherein the aerosol forming material comprises at least 5% by weight of the aerosol generating material.

25 . The article of claim 1 ,
wherein the pressure difference across the mouthpiece is less than 32 mmH2O.

26 . A system comprising an article according to claim 1 , and a non-combustible aerosol provision device for heating the aerosol generating material of the article.

27 . The system of claim 26 , wherein the non-combustible aerosol provision device comprises a coil.

28 . The system of claim 26 , wherein the non-combustible aerosol provision device is configured to heat the aerosol generating material of the article to a maximum temperature of at least 200° C.

29 . The system of claim 28 , wherein the non-combustible aerosol provision device is configured to heat the aerosol generating material of the article to a maximum temperature of at least about 160° C., or at least about 200° C., or at least about 220° C., or at least about 240° C., or at least about 270° C.
