Abstract:
There is provided an aerosol-generating article (10) comprising an aerosol-generating substrate (12) and a mouthpiece (14) secured to a downstream end of the aerosol-generating substrate (12). The mouth piece (14) comprises at least one segment of porous filter material (20) and a blocking segment (27) that impedes air flow downstream of the at least one segment of porous filter material (20). The blocking segment (27) comprises a segment of support material (22) having an annular shape defining a channel (24) extending through at least part of the segment of support material (22), and at least one freshener delivery element (26) contained within the channel (24). The blocking segment (27) comprising the at least one freshener delivery element (26) is detachable from the at least one segment of porous filter material (20) to decrease the resistance to draw of the aerosol-generating article (10).
Abstract:
An aerosol generating article (10) comprises an aerosol generating substrate (12), a mouthpiece (14) in axial alignment with the aerosol generating substrate (12), and a tipping wrapper (20). The tipping wrapper (20) comprises a first weakening line (22) extending circumferentially around at least a portion of the tipping wrapper; a removable tipping wrapper portion (26) extending downstream from the at least one weakening line (22); an upstream tipping wrapper portion (24) extending upstream from the first weakening line; and a longitudinal edge (28) extending along the outer surface of the mouthpiece. The longitudinal edge (28) comprises a tipping wrapper projection (32) downstream of the at least one weakening line (22) and a first straight line portion (30) extending upstream of the tipping wrapper projection (32), wherein the tipping wrapper projection (32) comprises a first curved transition portion (38) connecting the first straight line portion (30) to the remainder of the tipping wrapper projection and wherein the first curved transition portion (30) follows a convex curve.
Abstract:
A smoking article (10) incorporates a sustained release liquid delivery material (20), the liquid delivery material comprising a closed matrix structure defining a plurality of domains. A liquid composition is trapped within the domains and is releasable from the closed matrix structure upon compression of the material. The liquid delivery material (20) provides a sustained release of the liquid composition over a range of force of at least 5 Newtons. Preferably, the liquid delivery material is provided within the filter (14) of the smoking article (10).
Abstract:
A method for the production of a flavour granule for a smoking article comprises the steps of: a) forming an inner core by compaction of particles of herbaceous plant material; b) providing a coating suspension of coloured binder particles comprising at least one colourant and at least one polymeric binder in a solvent; c) applying the coating suspension to the outer surface of the inner core to form an outer layer, wherein the coating suspension is applied to the inner core within a coating system and wherein within that coating system the vapour pressure of the solvent is greater than 5 kPa; and d) drying the outer layer to evaporate the solvent.
Abstract:
The present invention relates to a smoking article (8) comprising a smokeable material and a mouthpiece (1), the mouthpiece comprising at least three segments (2, 3, 5) in axial alignment. One segment defining a cavity (5) is disposed between two other segments (2, 3) and a fluid-containing breakable capsule (6) is arranged in the cavity. A first wrapper (4) circumscribes at least the cavity, wherein the first wrapper comprises a substantially smooth transparent section overlaying at least a part of the cavity, such that the capsule is at least partially visible through the first wrapper. The first wrapper has one or more layers of transparent varnish applied thereto. The invention further relates to a mouthpiece for a smoking article and a method of producing a smoking article.
Abstract:
A smoking article includes a tobacco substrate and a filter segment comprising filtration material axially aligned in an abutting end to end relationship with the tobacco substrate. A hydrophobic plug wrap is disposed about the filtration material. The plug wrap is hydrophobic via hydrophobic groups chemically bonded to the plug wrap.
Abstract:
There is provided an aerosol-generating 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 at least one segment of filter material (20) and a vented segment (27) downstream of the at least one segment of filter material (20) and comprising at least one freshener delivery element (26). The vented segment (27) comprising the at least one freshener delivery element (26) is detachable from the at least one segment of filter material (20) to decrease the ventilation of the aerosol-generating article (10).
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 filter for a smoking article, the filter including a hollow tube of filter material having an outer diameter and an inner diameter. The filter further includes a flow restrictor disposed in the hollow tube. At least one cross sectional dimension of the flow restrictor is larger than the inner diameter of the hollow tube, such that the flow restrictor engages with the hollow tube to retain the flow restrictor in the hollow tube. There is also provided a smoking article including such a filter.
Abstract:
A smoking article (10) comprises a tobacco rod (12) and a filter (14) connected to the tobacco rod. The filter (14) comprises a flow restrictor (24). The smoking article further comprises a ventilation zone (18) at a location along the filter downstream of the flow restrictor. The diameter of the tobacco rod (12) is from about 5 mm to about 8.5 mm, the tobacco packing density within the tobacco rod is from about 180 mg/cubic centimetre to about 280 mg/cubic centimetre, and the length of the tobacco rod is from about 15 mm to about 45 mm. Further, the tobacco rod (12) is circumscribed by a wrapper (13) having an air permeability of less than about 20 Coresta units, the wrapper being made of a transparent regenerated cellulose film, or cellophane.
