Problems solved by technology

However, this solution may not always work
For example, this solution may not be efficient when the mouth-end cavity is formed from discrete hollow tubular segments such as hollow tubes of fibrous material, since it cannot be easily printed on such fibrous material

Embodiment Construction

[0042] figure 1 with figure 2 An aerosol-generating article 10 according to a first embodiment of the invention is shown. The article is in the form of a smoking article. The smoking article 10 comprises an aerosol-forming substrate in the form of a wrapped rod 12 of tobacco filler. The rod 12 is attached to one end of the mouthpiece in the form of an axially aligned filter 14 . A strip of tipping paper 16 surrounds the filter 14 and a portion 120 of the tobacco wrapping rod 12 to bond the two portions of the smoking article 10 together.

[0043] Such as figure 2 As shown, the filter 14 includes a hollow tubular section 24 . The hollow tubular section 24 comprises a hollow tube 31 of crimped fibrous material in the form of cellulose acetate tow. The hollow tubular section 24 is located at the downstream end of the filter 14 and defines a mouth end cavity 40 of the article 10 . Upstream of the hollow tubular section 24 is a filter section 30 which is also formed from a...

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 ahollow 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).

Description

technical field [0001] The present invention relates to aerosol-generating articles having a mouth end cavity. The invention is particularly applicable to filter cigarettes having a mouth end cavity. Background technique [0002] Filter cigarettes are an example of an aerosol-generating article. Filter cigarettes generally comprise a rod of tobacco filler surrounded by a wrapper and a cylindrical filter aligned in end-to-end relationship with the wrapped tobacco rod, the filter being attached to the tobacco rod with tipping paper. In conventional filter cigarettes, the filter may consist of a rod of cellulose acetate tow wrapped in a porous plug wrap. Filtered cigarettes are also known having multi-component filters comprising two or more segments of filter material for removing particulate and gaseous components of mainstream smoke. Aerosol-generating articles having a cavity at the mouth end have also been proposed. [0003] A number of aerosol-generating articles have...
