Abstract
An aerosol-generating article (10) comprising: an aerosol generating substrate (12); and a mouthpiece (14) disposed downstream of the aerosol-generating substrate (12). The mouthpiece (14) comprises a hollow tubular segment (24) at its downstream end defining a mouth end cavity (40). The hollow tubular segment (24) comprises a hollow tube (31) of crimped fibrous material, and a plurality of non-crimped fibers (35) extending along and affixed to the inner surface (311) of the hollow tube (31).
Claims15
An aerosol-generating article comprising:
- an aerosol-generating substrate and a mouthpiece disposed downstream of the aerosol-generating substrate, the mouthpiece comprising:
- a hollow tubular segment at its downstream end defining a mouth end cavity, the hollow tubular segment comprising:
- a hollow tube of crimped fibrous material;
- and
- a plurality of non-crimped fibers extending along and affixed to the inner surface of the hollow tube,
- wherein (i) the hollow tube of crimped fibrous material and (ii) the plurality of non-crimped fibers extending along and affixed to the inner surface of the hollow tube together form the hollow tubular segment.
A hollow tubular segment for a mouthpiece of an aerosol-generating article, the segment comprising:
- a hollow tube of crimped fibrous material, and a plurality of non-crimped fibers extending along and affixed to the inner surface of the hollow tub,
- wherein (i) the hollow tube of crimped fibrous material and (ii) the plurality of non-crimped fibers extending along and affixed to the inner surface of the hollow tube together form the hollow tubular segment.
A method of forming a hollow tubular segment for a mouthpiece of an aerosol-generating article, the method comprising:
- conveying a first continuous band of crimped fibers;
- conveying a second continuous band of non-crimped fibers;
- shaping a portion of the first continuous band into a substantially annular shape having an outer surface and an inner surface;
- conveying the second continuous band into contact with the inner surface of the substantially annular shaped portion of the first continuous band;
- and
- affixing the contacted portions together and cutting a segment of the affixed portions from the continuous band to form a hollow tubular segment for a mouthpiece of an aerosol-generating article such that (i) the crimped fibers and (ii) the non-crimped fibers together form the hollow tubular segment.
