Definitions

  • This invention relates to the tobacco industry and relates to a rod-shaped, multisegment article defining, or intended to define, a smoking article or for generating aerosols. More in detail, the invention relates to a multisegment article which can be penetrated by a heating element, for example pinshaped or needle-shaped, of a heating device, such as, for example, an electronic cigarette.
  • a heating element for example pinshaped or needle-shaped
  • this invention addresses the field of Heat-not-Burn (HNB) smokers’ articles.
  • an article of that type comprises, close to a relative end, an aerosol-generating segment which is able to release an aerosol when heated, containing, for example, strips of tobacco or containing a tobacco aroma or nicotine-based, or a gathered sheet of tobacco or containing a tobacco aroma or nicotine-based.
  • the aerosol-generating segment could be formed by pieces of tobacco or containing a tobacco aroma or nicotine-based or cut tobacco.
  • an aerosol-generating segment which is able to release an aerosol when heated may comprise any substrate of organic origin, in particular of vegetable origin (for example, tobacco, cotton, linen, rapeseed, cellulose, alginates, hemp, paper).
  • the prior art in order to produce aerosols which can be inhaled by a user, the prior art teaches the penetration of the aerosol-generating segment by means of the heating element of a heating device, such as, for example, an electronic cigarette.
  • the withdrawal may, however, cause a pulling and consequent dispersion into the environment outside the article of portions of the aerosol-generating segment, such as, for example, powder, tobacco parts, ash.
  • This dispersion is amplified if the aerosol-generating segment comprises pieces of tobacco or cut tobacco or strips of tobacco (or containing a tobacco aroma or nicotine-based flavour) gathered and, if necessary, compressed, but not anchored in any way to an outer wrapper of the article.
  • the article is provided with a terminal segment, positioned at an end of the article proximal to the aerosol-generating segment, which can also be penetrated by the heating element of a heating device.
  • the terminal segment is configured for retaining any portions of the aerosol-generating segment drawn during a withdrawal from the article of the heating element.
  • the aim of the invention is therefore to provide an article with a terminal segment alternative to the prior art solutions, which allows a simplified production and with improved efficiency.
  • the Applicant has found that the inclusion in the terminal segment of an insert having a predetermined shape, shaped in such a way as to partly occupy the transversal cross-section of the outer tubular element so that it can be penetrated by a heating element, preferably with a needle shape, and in particular a shaped insert obtained by folding a sheet or web, considerably simplifies the production because traditional machines operating continuously may be used for this type of production, in particular machines with forming beams. These machines can be, for example, of the type described in patent document W02020/128827 or WO2021/171186 in the name of the Applicant.

L'article (1) comprend un segment de génération d'aérosol (4) positionné à proximité d'une extrémité (1a) de l'article, et un segment terminal (3) positionné au niveau de l'extrémité (1a), tous deux pouvant être pénétrés par un élément chauffant (302). Le segment terminal (3) comprend un élément tubulaire externe (3a) et un élément inséré profilé (3b), ayant une forme prédéterminée, disposé à l'intérieur du tube externe (3a) et dont la forme lui permet d'obstruer partiellement la section transversale de l'élément tubulaire externe (3a) de telle sorte que le segment terminal (3) puisse être pénétré par un élément chauffant (302), en particulier sans déformer l'élément inséré profilé (3b).
