  • providing the component 4 at an upstream end of the article 1 can provide several advantages.
  • the stability of the article 1, in use may be improved, by preventing fall-out of aerosol-generating material from the upstream end of the article 1.
  • the component 4 comprises a body of material having a resistance to draw between about 5% and 25% of the resistance to draw of the article 1 this can also result in greater consistency of resistance to draw between articles, since the contribution of the rod of aerosol generating material 2 to the overall resistance to draw of the article 1 is relatively less.
  • the relatively high resistance to draw of the component 4 can make the overall resistance to draw of the article 1 less sensitive to variations in the resistance to draw of the rod of aerosolgenerating material 2.
  • the component 4 is connected to the rod of aerosol generating material 2 by a connecting wrapper 7.
  • the connecting wrapper 7 is a paper wrapper.
  • the connecting wrapper 7 may be a paper backed foil wrapper, or a metal foil.

  • a non-combustible material such as a metal foil
  • the connecting wrapper 7 circumscribes substantially the entire length of the component 4 and the rod of aerosol generating material 2.
  • connecting the component 4 to the rod of aerosol generating material 2 with a connecting wrapper 7 which extends over substantially the entire length of the rod of aerosol generating material 2 can provide additional strength and rigidity to the rod of aerosol generating material.
  • This can be particularly advantageous where the aerosol generating material is less densely packed, or provided in a form having an inherently lower level of structural stability, such as granular tobacco.
  • the connecting wrapper 7 is adhered to both the component 4 and the rod of aerosol- generating material 2. At least part of the inner surface of the connecting wrapper 7 is covered by a layer of adhesive. It has been surprisingly found that applying a reduced amount of adhesive to the connecting wrapper 7 can result in the formation of an improved aerosol. This may be achieved by reducing the thickness of the layer of adhesive, or preferably by providing gaps in the layer of adhesive. Preferably, the layer of adhesive is discontinuous. For example, prior to combining the component 4 and the tobacco rod 2, adhesive may be applied to the connecting wrapper 7 in bands, such that the remaining portions of the connecting wrapper 7 are entirely free of adhesive.
  • portions of the component 4 and the rod of aerosol-generating material 2 may be free of adhesive.
  • the bands of adhesive may extend in the same direction as the longitudinal axis of the article, perpendicular to the longitudinal axis of the article, or at another angle, such as diagonal to the longitudinal axis.
  • Providing a discontinuous layer of adhesive on the inner surface of the connecting wrapper 7 may advantageously improve the ease of manufacture of the article 1, since less of the connecting wrapper 7 is wetted by the adhesive which can result in a higher tensile strength of the connecting wrapper 7 during manufacture.
  • the adhesive layer may be applied in a different pattern, for instance a dot matrix.
  • At least a portion of the area of the inner surface of the connecting wrapper 7 is free of adhesive.
  • at least 30%, at least 40%, or at least 50% of the area of the inner surface of the connecting wrapper 7 is free of adhesive.
  • the connecting wrapper 7 has a tensile strength of at least 2.5 kgf/ 15mm, for instance at least 3 kgf/ 15mm, or at least 3.5 kgf/ 15mm.
  • the tensile strength of the connecting wrapper 7 may be determined in accordance with the test method T 494.
  • the connecting wrapper 7 has a permeability of at least 3 Coresta
  • the connecting wrapper 7 has a permeability of at least 5 Coresta Units, at least 10 Coresta Units, or at least 20 Coresta Units. In some examples, this permeability is an inherent property of the connecting wrapper 7. In other examples, the connecting wrapper 7 may be provided with perforations to increase the material permeability. In some examples, the combined permeability of the rod wrapper 10 and the connecting wrapper 7, together with any intermediate layer of adhesive, is at least 25 Coresta Units, or at least 30 Coresta Units, or at least 50 Coresta Units.
  • the combined permeability of the rod wrapper 10 and the connecting wrapper 7 together with any intermediate layer of adhesive may be determined by breaking down the article 1 to separate the wrapping materials from the rod of aerosol-generating material, and measuring the total permeability through the wrapping materials surrounding the rod of aerosol-generating material, i.e., the rod wrapper 10, the connecting wrapper 7, and any intermediate layer of adhesive, in accordance with ISO 2965:2019.
  • connecting wrapper 7 has a basis weight between about 27 gsm and about 70 gsm, for instance between about 36 gsm and about 50 gsm, or about 36 gsm, about 41 gsm, about 44 gsm or about 48 gsm. Using a basis weight in these ranges provides a configuration having improved firmness and resilience of the article, for instance during and after use of the article with a heating device as described herein.
  • the component 4 is adjacent to an upstream end of the rod of aerosol generating material 2.
  • more than one component may be provided upstream of the rod of aerosol-generating material.
  • a first component 4 may be provided at the upstream end of the article, and a second component may be provided in between the first component 4 and the rod of aerosol generating material 2.
  • the article 1 has an outer circumference of about 21 mm (i.e. the article is in the demi-slim format).
  • the article 1 has a rod of aerosol generating material having a circumference greater than 19 mm. This has been found to provide a sufficient circumference to generate an improved and sustained aerosol over a usual aerosol generation session preferred by consumers.
  • the article As the article is heated, heat transfers through the rod of aerosol generating material 2 to volatise components of the aerosol generating material, and circumferences greater than 19 mm have been found to be particularly effective at producing an aerosol in this way. Since the article is to be heated to release an aerosol, improved heating efficiency can be achieved using articles having circumferences of less than about 23 mm. To achieve improved aerosol via heating, while maintaining a suitable product length, rod circumferences of greater than 19 mm and less than 23 mm are preferable. In some examples, the rod circumference can be between 20 mm and 22 mm, which has been found to provide a good balance between providing effective aerosol delivery while allowing for efficient heating.
  • the outer circumference of the mouthpiece 2 is substantially the same as the outer circumference of the rod of aerosol generating material 3, such that there is a smooth transition between these components.
  • the outer circumference of the mouthpiece 2 is about 20.8 mm.

  • the length of the mouthpiece body 14 may be increased, or a further body of material may be provided at the mouth end.
  • the cooling section 13 defines an air gap within the mouthpiece.
  • the air gap provides a chamber through which heated volatilised components generated by the rod of aerosol generating material 2 flow.
  • the cooling section 13 is hollow to provide a chamber for aerosol accumulation yet rigid enough to withstand axial compressive forces and bending moments that might arise during manufacture and whilst the article 1 is in use.
  • the cooling section 13 provides a physical displacement between the rod of aerosol generating material 2 and downstream portions of the mouthpiece 3.
  • the internal volume of the cooling section 13 is greater than 130 mm3. Providing a cavity of at least this volume has been found to enable the formation of an improved aerosol. Such a cavity size provides sufficient space within the mouthpiece 2 to allow heated volatilised components to cool, therefore allowing the exposure of the aerosol generating material 2 to higher temperatures than would otherwise be possible, since they may result in an aerosol which is too warm. More preferably, the mouthpiece 3 comprises a cavity having an internal volume greater than 170 mm3, and still more preferably greater than 200 mm3, allowing further improvement of the aerosol. In some examples, the internal cavity comprises a volume of between about 130 mm3 and about 700 mm3 and, preferably, between about 160 mm3 and about 700 mm3.

  • the length of the cooling section 13 is less than about 50 mm. More preferably, the length of the cooling section 13 is less than about 40 mm.
