There is provided a smoking article that includes a plurality of elements, including a front-plug and an aerosol-forming substrate, assembled in contact with a cigarette paper to form a rod. The front-plug is located upstream from the aerosol-forming substrate. In use, a heating element is inserted into the smoking article and the aerosol-forming substrate is heated to generate an aerosol. When the heating element is subsequently withdrawn from the smoking article, the front-plug acts to retain the aerosol-forming substrate within the rod.

A method of designing a target combustible tobacco product, the method comprising receiving respective values for a plurality of input parameters (101); calculating respective values for a plurality of design parameters (130) for the combustible tobacco product based on the received values for the plurality of input parameters, and providing the calculated values as an output. The plurality of design parameters comprise at least two parameters selected from: a tobacco blend composition; tar, nicotine and carbon monoxide deliveries; a smoke sensory attribute; a number of puffs associated with the combustible tobacco product; combustible tobacco product dimensions; tobacco weight; tobacco rod and/or filter density; tobacco rod and/or filter firmness; open and/or closed combustible tobacco product pressure drop; filter pressure drop; cigarette paper porosity; and ventilation level.

This invention relates to a lyocell material for a tobacco filter and a method of manufacturing the same, and more particularly to a lyocell fiber having a modified cross-section for a tobacco filter, wherein the cross-sectional shape of a monofilament contained in a lyocell fiber is controlled to increase the external surface area of the fiber, after which then crimps are formed, thereby exhibiting properties equal or superior to those of conventional lyocell materials, even when used in a small amount.

The non-combustible tobacco vaping insert includes a filter having a first diameter, and a tobacco element with a first end contacting the filter, the tobacco element having a second diameter that is smaller than the first diameter of the filter. The cartridge includes a housing, where the cartridge defines an air passage within the housing, and a vaping insert is positioned in at least one first portion of the air passage. The vaping insert is non-combustible and is configured to allow vapor to pass through the vaping insert prior to exiting the cartridge. The vaping insert includes a filter having a first diameter, and a tobacco element with a first end contacting the filter, the tobacco element having a second diameter that is smaller than the first diameter of the filter.

The non-combustible tobacco vaping insert includes a filter having a first diameter, and a non-combustible tobacco element with a first end contacting the filter. At least one first portion of the tobacco element has a second diameter that is smaller than the first diameter of the filter. The cartridge includes a heater configured to vaporize a pre-vapor formulation that is communicated to the heater by a wick. The insert is positioned in at least a portion of an air passage within cartridge, where the insert is configured to allow vapor that is generated by the heater to pass through the insert prior to being discharged from the cartridge.

There is provided a method and apparatus for manufacturing filters for smoking articles. The method comprises providing hollow tubes (309) of filter material. Each hollow tube has an outer diameter and an inner diameter. The method further comprises providing filter inserts (205). Each filter insert (205) has a first portion having a cross sectional dimension larger than the inner diameter of the hollow tube. The method further comprises inserting each filter insert (205) into a hollow tube (309) of filter material. During inserting, the first portion of the filter insert (205) engages with the hollow tube (309) to retain the filter insert in the hollow tube.

Disclosed are fibers comprising identification fibers which can be used for tracking and tracing fibers, yarns, fiber bands, and/or articles comprising the fibers through at least part of the supply chain. Each identification fiber exhibits at least one distinct feature. Each group of distinguishable identification fibers can exhibit a taggant cross-section shape, a taggant cross-section size, or combination of the same taggant cross-section shape and same taggant cross-section size. The distinct features and the number of fibers in each group of distinguishable identification fibers can represent at least one supply chain component of the fibers. The distinct features can be detectable in an article comprising the fibers.
