Abstract: A hollow tubular element (100) for an aerosol-generating article (1), the hollow tubular element (100) comprising: a peripheral portion (110) providing a curved outer surface of the hollow tubular element (100), and defining a hollow inner region (120) of the hollow tubular element (100); and an internal projection (130) extending into the hollow inner region (120). The hollow tubular element (100) is formed from a sheet, the sheet comprising: a first part and a second part adjacent to the first part with a first fold line (141) therebetween. The first part of the sheet forms at least part of the peripheral portion (110) of the hollow tubular element (100). The entirety of the first part of the sheet forms at least part of the curved outer surface of the hollow tubular element (100).

Abstract: An aerosol-generating article (1) comprising: a first element (10) comprising an aerosol-forming substrate (12); a susceptor element (20) arranged within the first element (10); and a hollow tubular element (100) disposed downstream of the first element (10). The hollow tubular element (100) comprises: a peripheral portion (110) defining a hollow inner region (120) of the hollow tubular element (100); and a support element (130) formed from a paper sheet and extending from a first point (131) at the peripheral portion (110) across the hollow inner region (120) to a second point (132) at the peripheral portion (110).

Abstract: A tubular element for an aerosol-generating article is provided, the tubular element including: a tubular body defining a cavity extending from a first end of the tubular body to a second end of the tubular body; a folded end portion forming a first end wall at the first end of the tubular body, the first end wall delimiting an opening for airflow between the cavity and an exterior of the tubular element; and a ventilation zone at a location along the tubular body of the tubular element, the ventilation zone being located between about 5 millimetres and about 15 millimetres from the folded end portion of the tubular element.

Abstract: An aerosol-generating article including a plurality of elements assembled in the form of a rod is provided, the elements including: a first element including an aerosol-generating substrate; and a tubular element positioned upstream or downstream of the first element, the tubular element including: a tubular body defining a cavity extending from a first end of the tubular body to a second end of the tubular body, and a folded end portion forming a first end wall at the first end of the tubular body, the first end wall delimiting an opening for airflow between the cavity and an exterior of the tubular element, the cavity in the tubular element being an empty cavity.

Abstract: A method of manufacturing a component for an aerosol-generating article including a taggant is provided, the method including the steps of: applying the taggant to the component; detecting an amount of the taggant that the component comprises; determining whether the detected amount of the taggant is less than a first-predetermined amount; and rejecting the component when the detected amount of the taggant is less than the first-predetermined amount. An apparatus for manufacturing a component for an aerosol-generating article including a taggant is also provided. A kit of parts is also provided.

Abstract: An aerosol-generating article is provided, including: a substrate portion containing an aerosol-forming substrate; and a connect portion disposed at one end of the aerosol-generating article in direct abutment with the substrate portion, the connect portion having a tubular empty core structure, the substrate portion having a length of between 20 millimeters and 60 millimeters, and a diameter of between 4 millimeters and 7 millimeters, the aerosol-forming substrate including an aerosol former, and an amount of the aerosol former ranges between 6 percent and 20 percent by weight on a dry weight basis of the aerosol-forming substrate. An aerosol-generating system including the aerosol-generating article and an aerosol-generating device, and a method for manufacturing the aerosol-generating article, are also provided.
