Description

[0147] Examples will now be further described with reference to the figure in which:

[0148] FIG. 1 shows a schematic longitudinal cross-sectional view of an aerosol generating article according to the present invention; and

[0149] FIG. 2 shows a schematic longitudinal cross-sectional view of an aerosol generating system comprising an aerosol generating article according to the invention in cooperation with an aerosol generating device.

[0150] The aerosol-generating article 10 shown in FIG. 1 comprises an aerosol-forming substrate 12 and a downstream section 14 at a location downstream of the aerosol-forming substrate 12. Further, the aerosol-generating article 10 comprises an upstream element 16 at a location upstream of the aerosol-forming substrate 12. Thus, the aerosol-generating article 10 extends from an upstream or distal end 18 to a downstream or mouth end 20.

[0151] The aerosol-generating article 10 has an overall length of about 30 millimetres.

[0152] The downstream section 14 comprises a support element 22 located immediately downstream of the aerosol-forming substrate 12, the support element 22 being in longitudinal alignment with the aerosol-forming substrate 12. In the embodiment of FIG. 1, the upstream end of the support element 18 abuts the downstream end of the aerosol-forming substrate 12. In addition, the downstream section 14 comprises an aerosol-cooling element 24 located immediately downstream of the support element 22, the aerosol-cooling element 24 being in longitudinal alignment with the rod 12 and the support element 22. In the embodiment of FIG. 1, the upstream end of the aerosol-cooling element 24 abuts the downstream end of the support element 22.

[0153] As will become apparent from the following description, the support element 22 and the aerosol-cooling element 24 together define an intermediate hollow section 50 of the aerosol-generating article 10. As a whole, the intermediate hollow section 50 does not substantially contribute to the overall RTD of the aerosol-generating article.

[0154] The support element 22 comprises a first hollow tubular segment 26. The first hollow tubular segment 26 is provided in the form of a hollow cylindrical tube made of cellulose acetate. The first hollow tubular segment 26 defines an internal cavity 28 that extends all the way from an upstream end 30 of the first hollow tubular segment to an downstream end 32 of the first hollow tubular segment 26. The internal cavity 28 is substantially empty, and so substantially unrestricted airflow is enabled along the internal cavity 28.

[0155] The aerosol-cooling element 24 comprises a second hollow tubular segment 34. The second hollow tubular segment 34 is provided in the form of a hollow cylindrical tube made of cellulose acetate. The second hollow tubular segment 34 defines an internal cavity 36 that extends all the way from an upstream end 38 of the second hollow tubular segment to a downstream end 40 of the second hollow tubular segment 34. The internal cavity 36 is substantially empty, and so substantially unrestricted airflow is enabled along the internal cavity 36. The second hollow tubular segment 28and, as a consequence, the aerosol-cooling element 24does not substantially contribute to the overall RTD of the aerosol-generating article 10.

[0156] The aerosol-generating article 10 comprises a ventilation zone 60 provided at a location along the second hollow tubular segment 34. In more detail, the ventilation zone is provided at about 2 millimetres from the upstream end of the second hollow tubular segment 34. A ventilation level of the aerosol-generating article 10 is about 25 percent.

[0157] In the embodiment of FIG. 1, the downstream section 14 further comprises an optional mouthpiece element 42 at a location downstream of the intermediate hollow section 50. In more detail, the mouthpiece element 42 is positioned immediately downstream of the aerosol-cooling element 24. As shown in the drawing of FIG. 1, an upstream end of the mouthpiece element 42 abuts the downstream end 40 of the aerosol-cooling element 18.

[0158] The mouthpiece element 42 is provided in the form of a cylindrical plug of low-density cellulose acetate.

[0159] The aerosol-generating article 10 further comprises an elongate susceptor element 44 within the aerosol-forming substrate 12. In more detail, the susceptor element 44 is arranged substantially longitudinally within the aerosol-forming substrate, such as to be approximately parallel to the longitudinal direction of the rod 12. As shown in the drawing of FIG. 1, the susceptor element 44 is positioned in a radially central position within the aerosol-forming substrate 12 and extends effectively along the longitudinal axis of the aerosol-forming substrate 12.

[0160] The susceptor element 44 extends all the way from an upstream end to a downstream end of the aerosol-forming substrate 12. In effect, the susceptor element 44 has substantially the same length as the aerosol-forming substrate 12 of aerosol-forming substrate.

[0161] The upstream element 46 is provided in the form of a cylindrical plug of cellulose acetate circumscribed by a stiff wrapper.

[0162] The aerosol-generating article 10 further comprises an odour inhibition substrate 60. The odour inhibition substrate 10 is in the form of a band formed by a strip of paper material circumscribing the mouthpiece element 42. The strip of paper is attached to the wrapper using an adhesive. The strip of paper is disposed about 12 millimetres downstream of the downstream end 20 of the aerosol generating article 10. The strip of paper in impregnated with at least 10 different odour components. Details of suitable combinations of odour components are set out below.

[0163] As shown in FIG. 2, in use, the aerosol generating article 10 is inserted into an aerosol generating device 65. An induction coil in the aerosol generating device inductively heats the susceptor 44 in the aerosol generating article 10. The heating susceptor 44 heats the aerosol-forming substrate 12. The aerosol-forming substrate 12 generates a vapour which cools and nucleates into an aerosol in the hollow section 50. A pressure drop at the downstream end 20 of the aerosol generating article 10 draws air into the aerosol generating article 10 through the air inlets 60. The air drawn though the air inlets 60 entrains vapour from the aerosol-forming substrate 12. This air entrained with vapour then passes through the mouthpiece 42 and out of the downstream end of the aerosol generating article 10.

[0164] At the same time, the odour inhibition substrate 60 which is disposed outside of the aerosol generating article 10, releases odour inhibition molecules from the at least 10 different odour components. These molecules released from the at least 10 different odour inhibition produces an olfactory white which prevents the user from identifying the unpleasant odours generated by the aerosol-forming substrate.

[0165] Examples of suitable combinations of odour components which have been found to produce an olfactory white are set out below. The specific combinations of odour components are listed as Ex-1 to Ex-34 and are set out in Tables 1 to 4. The odour components of each example are identified by the chemical's PubMed CID number. The names of each odour component corresponding to each CID number are set out in Table 5 below.

[0166] Table 1 shows three Examples, Ex-1, Ex-2, and Ex-3. Ex-1 and Ex-2 each include 60 different odour components. There is also no overlap between Ex-1 and Ex-2. Example Ex-3 includes 30 different odour components.

[0167] Table 2 shows 5 Examples from Ex-4 to Ex-8. Each of Ex-4 to Ex-8 include 30 different odour components and span a physicochemical space.

[0168] Table 3 shows 12 Examples from Ex-9 to Ex-20. Ex-9, Ex-10, Ex-15, and Ex-16 each include 10 different odour components. Ex-11, Ex-12, Ex-17, and Ex-18 each include 20 different odour components. Ex-13, Ex-14, Ex-19, and Ex-20 each include 30 different odour components. The specific selection of odour components in Examples Ex-9 to Ex-20 were selected based on the odour perceptual space.

[0169] Table 4 shows 14 Examples from Ex-21 to Ex-34. Ex-21, Ex-22, Ex-27, and Ex-28 each include 10 different odour components. Ex-29 and Ex-30 each include 15 different odour components. Ex-23, Ex-24, Ex-31, and Ex-32 each include 20 different odour components. Ex-25, Ex-26, Ex-33, and Ex-34 each include 30 different odour components. The specific selection of odour components in Examples Ex-21 to Ex-34 were selected based on the odour physicochemical space.
