Abstract: A method for enhancing hardness of a filter for a smoking article includes disposing a plug wrap about filter material; and applying a hardness-enhancing coating composition to the plug wrap after the plug wrap has been disposed about the filter material to enhance the hardness of the filter.

Abstract: A smoking article (10) comprising: an aerosol-generating substrate (12) and a mouthpiece (14) secured to a downstream end of the aerosol-generating substrate (12). The mouthpiece (14) comprises a first segment (24) of elastically deformable material, the first segment (24) having a length in the longitudinal direction of the mouthpiece (14) and a width transverse to its length. The first segment (24) comprises an insert unit access portion comprising at least one slit (60) extending along at least a part of the length of the first segment (14), and extending across at least a part of the width of the first segment (14) to facilitate deformation of the access portion, such that an opening (25) is formable or expandable in the access portion of the first segment (14) upon receiving an insert unit (50).

Abstract: There is provided a smoking article (10) comprising: a charge (12) of tobacco material; a wrapper (14) circumscribing the charge (12) of tobacco material; a filter (16) arranged downstream of the charge (12) of tobacco material; and a hollow tube (18) defining an inner cavity (20) and attaching the filter (16) to the wrapper (14). An affixing portion (22) of the wrapper (14) is received within the inner cavity (20) and permanently secured to the hollow tube (18). A downstream end of the charge (12) of tobacco material is secured to the wrapper (14) by means of a thermally deactivatable adhesive (28) provided on an outer surface of the charge (12) of tobacco material or on an inner surface of the wrapper (14) or on both such that, upon deactivation of the adhesive (28), at least a portion of the charge (12) of tobacco material becomes slidable within the wrapper (14) in relation to the filter (16).

Abstract: There is provided a smoking article (10) comprising: a tobacco rod (12) comprising a charge (16) of tobacco material circumscribed by a wrapper (18); a filter (14) arranged downstream of the tobacco rod (12); and a hollow tube (20) defining an inner cavity (22) and attaching the filter (14) to the tobacco rod (12). An affixing portion (24) of the tobacco rod (12) is received within the inner cavity (22) and secured to the hollow tube (20) by means of a thermally deactivatable adhesive (26) provided on an outer surface of the wrapper (18) or on an inner surface of the hollow tube (20) or on both. Thus, upon deactivation of the adhesive, at least a portion of the tobacco rod (12) becomes slidable within the hollow tube (20) in relation to the filter (14).

Abstract: An aerosol-generating article (10) includes an aerosol forming substrate (20) and a filter (30) downstream of the substrate. The filter comprises filter material comprising filaments having a linear density of about 4 denier or greater. The filter has a resistance to draw of less than 130 mmWG. Preferably, the filter has a resistance to draw of 90 mmWG or less. More preferably, the filter has a resistance to draw of 70 mmWG or less. Preferably, the density of the filter material is about 0.12 g/cm3 or greater.

Abstract: A tube (10) for temporary affixment to a mouthpiece of a smoking article (80), the tube (10) comprising an open upstream end, an open downstream end, an outer surface, and an inner surface defining a lumen for receiving the mouthpiece of the smoking article, the lumen extending from the open upstream end to the open downstream end; the tube further comprising a first ventilation zone (50) for providing ventilation into the lumen of the tube, the first ventilation zone comprising a first line of perforation holes (52) circumscribing the tube at a location at least 10 mm from the open downstream end of the tube.

Abstract: An aerosol-generating article (10) includes an aerosol forming substrate (20) and a filter (30) downstream of the substrate. The filter comprises filter material having filaments that are distributed throughout a transverse cross section of the filter. The filter comprises from about 7.5% by weight to about 11.5% by weight of plasticizer or from about 10.5% by weight to about 15% by weight of plasticizer. The filters may be hard, while maintaining suitable resistance to draw.

Abstract: An aerosol-generating article (10) includes an aerosol forming substrate (20) and a filter (30) downstream of the substrate. The aerosol-generating article has an average radial hardness of 95.5% or greater when measured around the filter. The filter has a resistance to draw of 70 mmWG or less.

Abstract: A smoking article assembly (100) comprising a smoking article (80), and a tube (10) for temporary affixment to the smoking article. The smoking article comprises a tobacco rod, and a mouthpiece comprising a filter and a tipping wrapper, the tipping wrapper circumscribing the filter and attaching the filter to the tobacco rod. The tube is configured to be disposed around at least a portion of the mouthpiece such that the tube is slidable over the outer surface of the tipping wrapper. The tube comprises an open upstream end; an open downstream end; an outer surface; and an inner surface defining a lumen for receiving the mouthpiece of the smoking article, the lumen extending from the open upstream end to the open downstream end. The coefficient of static friction between the inner surface of the tube and the outer surface of the tipping wrapper may be between about 0.5 and about 0.9.
