The mouthpiece (14) comprises a mouthpiece wrapper (30) circumscribing one or more mouthpiece segments (16). The tipping wrapper (20) comprises at least one weakening line (22) extending transversely around at least a portion of the tipping wrapper (20); an upstream wrapper portion (24) extending upstream from the at least one weakening line; and a removable tipping wrapper portion (26) extending downstream from the at least one weakening line (22). The mouthpiece wrapper (30) comprises at least one surface formation (28) underlying the removable tipping wrapper portion (26).

Provided is an aerosol generating article including a filter segment in which a channel is formed, the aerosol generating article including: a front-end filter segment arranged at an upstream end that is to be inserted into an aerosol generating device; a rear-end filter segment arranged at a downstream end that is to contact a mouth of a user; and a tobacco rod arranged between the front-end filter segment and the rear-end filter segment, wherein at least one filter segment of the front-end filter segment and the rear-end filter segment includes: at least one channel extending from the upstream end toward the downstream end; and a filter structure filtering out some components of aerosol, and wherein the at least one filter segment has a suction resistance corresponding to a ratio between a cross-sectional area of the at least one channel and a cross-sectional area of the filter structure.

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.

A filtered smoking article includes an aerosol generation rod, a filter disposed at a downstream end of the aerosol generation rod, and tipping paper wrapped around a downstream end part of the aerosol generation rod and an outer circumferential surface of the filter and connecting the aerosol generation rod and the filter. The tipping paper is paper containing bleached pulp and unbleached pulp, and fibers of the unbleached pulp have a length of 1 mm to 4 mm and a thickness of 20 m to 70 m.

Smoking articles are disclosed herein. The present disclosure is directed to a smoking article that comprises a heat source configured to generate heat upon ignition thereof, a substrate material having opposed first and second ends, the heat source being disposed proximate the first end of the substrate material and the substrate material having an aerosol precursor composition associated therewith, a mouthpiece, the mouthpiece being disposed proximate the second end of the substrate material, and a heat transfer component. In one implementation, the heat transfer component comprises a hollow structure and opposing first and second flanges located on respective ends thereof, wherein the hollow structure extends through the heat source such that the heat source is located between the first and second opposing flanges. In another implementation, the heat transfer component is located within the heat source, penetrates at least a portion of the substrate material, and includes a cap located between the heat source and the substrate material.

This filter for a tobacco product has: a fine-powder-containing article in which there is clumped a raw powder including a taste component and/or an aroma component, the fine-powder-containing article being formed into a powder by the application of force; a cavity in which the fine-powder-containing article is disposed; and a suction port filter part installed downstream of the cavity, the suction port filter part enabling communication between the cavity and an end of a suction port and having formed along the axial direction thereof a fine powder supply path for supplying fine powder from the cavity to the end of the suction port. The fine powder supply path includes a central connection part positioned at the center of a cross-section of the suction port filter part, and a plurality of hole parts extending in mutually different directions from the central connection part toward the outer periphery of the cross-section.

A product called IQOS, glo, or Ploom S sold as a heated tobacco product uses a filter-attached cigarette using tobacco leaves, which are treated to generate smoke by being heated, as tobacco leaves, in which the filter-attached cigarette is inserted into an exclusive heating jig, thereby allowing a user to enjoy nicotine and tobacco flavor evaporated by heating the tobacco leaves with an embedded heater. A smoking jig is provided having an electronic cigarette smoke generating part (e.g., an atomizer) mounted in the jig and configured to control, individually, a heater for heating tobacco leaves and a heater for generating electronic cigarette smoke, thereby allowing a smoker to smoke in accordance with his/her preference. Furthermore, the jig may also be used to cut tobacco leaves for a pipe or cut a filter-attached cigarette, which is used by burning, thereby enabling a smoker to enjoy smoking at a low running cost.

A cone shaped cigarette with hard tip and method for manufacture where a cone shaped paper encasement can contain shredded botanical material and a hard tip member having an inhaling aperture is inserted into the small end of the cone shaped paper encasement by an FDA approved adhesive. A filter member can be inserted into the tip of the hard tip member. A preferred embodiment includes the hard tip member being made of borosilicate glass. The hard tip member can be cylindrical in shape or cone shaped to match the side walls of the paper encasement. A preferred embodiment includes the glass hard tip member being transparent and the filter member is colored allowing the filter member to be viewed through the glass hard tip member.

A smoking article includes a tobacco rod comprising a column of filler and a wrapper surrounding the column of filler. The tobacco rod has a circumferential direction, a longitudinal direction, a lit end, and a mouth end. The wrapper includes a base web having generally parallel first and second side edges extending in the longitudinal direction and two ends extending in the circumferential direction wherein the base web is disposed around the column of filler such that the first and second side edges of the base web overlap and form a seam. The base web includes at least one circumferentially extending banded region of fibrous crystalline cellulosic material thereon. The fibrous crystalline cellulosic material is in a condition of having been gravure printed on the base web as a fibrous crystalline cellulosic slurry that comprises water, crystalline cellulose, and chalk wherein the fibrous crystalline cellulosic slurry has a solids content of about 10% or less by weight of the fibrous crystalline cellulosic slurry.

The invention relates to a cardboard filter (1) for cigarettes, formed by folding, winding and gluing a cardboard strip (2). According to the invention, the cardboard strip (2) is folded to form a central portion (21) having a series of lobes (3, 4, 5, 6, 7) angularly equally distributed around a central axis (22) of the filter (2) and a peripheral portion (23) surrounding the central portion (21), the lobes (3, 4, 5, 6, 7) and the peripheral portion (23) delimiting gas passage channels (24) around the central axis (22).
