Definitions

  • This invention relates to a smoking article and a filter for a smoking article, particularly but not exclusively a filter cigarette.
  • Conventional cigarettes typically comprise a cylindrical rod comprising a combustible smoking material that may be cut or shredded, for example tobacco, and retained in a paper wrapper, and a filter comprising a cut length of a rod of filter material such as cellulose acetate wrapped in a plug wrap, attached to the rod by tipping paper.
  • the resulting, so-called stick has a longitudinal axis and the buccal or mouth end of the filter has hitherto comprised a plane surface with a circular periphery, disposed orthogonally to the longitudinal axis.
  • the other or distal end of the cigarette comprises smoking material that is exposed ready to be lit, for example with a lighted match, having a plane surface that is disposed orthogonally to the longitudinal axis of the stick.
  • a smoking article described in WO 2009/045828 has a bevelled distal end which subtends an angle of 20° or more to a plane that is orthogonal to the longitudinal axis (less than 70° to the longitudinal axis).
  • This bevelled end configuration is described mainly in the context of heat-not-burn products in which the distal end contains a solid element of combustible material that is used to heat but not burn a charge of tobacco.
  • the solid element can be shaped into a configuration to provide an increased, elliptical area to assist in lighting the combustible material.
  • smoking article having a bevelled buccal end.
  • a filter for a smoking article having a bevelled buccal end.
  • Smoking articles in accordance with the invention provide clearly distinctive visual and tactile characteristics for the consumer.
  • the bevelled buccal end provides a distinctive tactile sensory response when inserted between the lips of the smoker's mouth.
  • smoking article includes smokeable products such as cigarettes, cigars and cigarillos, which usually incorporate cut or shredded material such as tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes, and also articles simulating such products for example so- called heat-not-burn products which contain tobacco or tobacco substitute materials and heating systems for volatilising flavour bearing materials therein without combustion, or aerosol products in which an aerosol of flavouring material is generated physically for inhalation.
  • the smoking article may comprise an elongate stick and the bevelled end may comprise at least one end surface of the stick inclined at a non-orthogonal angle to the longitudinal axis of the stick.
  • the end surface may comprise a single, plane end surface that may be inclined at an acute angle to a plane orthogonal to the longitudinal axis of the stick-.
  • the angle of inclination of the buccal end surface may lie within a range for which the minimum angle of inclination is preferably at least 2° although could be another larger value, such as at least 5 °, 7 °, 10°, 15° or 20°.
  • the maximum angle of inclination for the range is preferably not more than 60° although could be up to 50°, 40° 30° or 25 °.
  • the angle of inclination of the buccal end surface may lay within the range 40°-50° for example 45 ° or in the range 5 °-15 ° for example 10°.
  • the distal end of the smoking article may be bevelled.
  • smoking articles which incorporate cut or shredded material such as tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes, have a reduced propensity to shed such material from a bevelled distal end when the angle of the bevel is less than 20°.
  • the invention further provides a smoking article comprising an elongate body with a bevelled distal end having an end surface that subtends an angle of 20°or less to a plane that is orthogonal to the longitudinal axis of the body.
  • the bevelled distal end also provides distinctive visual and tactile characteristics for the consumer and the aforesaid feature of having a bevelled end surface that subtends an angle of 20°or less to a plane orthogonal to the longitudinal axis of the body has the advantage that combustible material in the body is retained within the body at the distal end.
  • the angle of inclination may advantageously greater than 5° but less than 15° e.g. about 10°, and the lower the angle, the lower the risk of smoking material falling out of the end of the cigarette during packaging and transport.
  • the bevelled end surface (s) are preferably planar, to facilitate manufacture using a straight cutting edge. However more complex, non-planar surfaces may be provided if desired, using cutters of correspondingly complex shapes
  • the invention also includes a method of manufacturing smoking articles comprising attaching tobacco rods to opposite ends of a rod of filter material, and cutting the rod of filter material at an angle such that both of the smoking articles thereby formed have bevelled ends with end surfaces at the same angle of inclination to the longitudinal axis of the respective smoking articles.
  • the invention also includes a method of producing a predetermined tactile sensory response in a person by inserting the smoking article with the bevelled buccal end between the lips of the person's mouth to create a predetermined sensory response when the lips embrace the buccal end.
  • the invention further includes a method of distinguishing between different types of smoking article, comprising providing first and second smoking articles that have different smoking characteristics with respective first and second different bevelled ends, and distinguishing between the different types on the basis of the different tactile sensory responses produced in a person by the different bevelled 1 ends.

Abstract

L'invention concerne un article à fumer sous la forme d'une cigarette (1) qui comprend un filtre (4) comprenant une surface d'extrémité buccale biseautée (2). L'extrémité buccale biseautée (2) offre également une réponse sensorielle tactile prédéfinie au consommateur lorsque la cigarette est insérée entre ses lèvres. La surface inclinée de l'extrémité biseautée (2) est perçue comme possédant un toucher différent et distinct des filtres classiques ayant une extrémité buccale orthogonale. Différentes extrémités buccales peuvent être utilisées pour faire la distinction entre différents types de cigarettes. L'invention concerne un procédé de fabrication de l'extrémité buccale biseautée. L'extrémité distale peut être biseautée afin d'empêcher le tabac de tomber de l'extrémité distale.
