A smoking article and a method of manufacturing a smoking article A smoking article has a filter section for receiving smoke and/or other aerosol generated by said smoking article, a variable ventilation arrangement configured to provide a user controllable level of ventilation into the filter section and a flavour source configured to release flavour to said smoke and/or other aerosol generated by said smoking article at a location in said smoke and/or other aerosol downstream of said ventilation arrangement.

A flavoring device includes a three-dimensional shape with a surface enclosing an inner volume, wherein the surface includes a first part directed outwardly of the three-dimensional shape and a second part being the lateral area of a cylindrically shaped hole protruding through the flavoring device, wherein the flavoring device includes a frame arranged at the surface of the three-dimensional shape and framing the inner volume at least in part, wherein the flavoring material is arranged within the frame, wherein the frame and the flavoring material are permeable to an air flow directed from a surrounding of the flavoring device through the first part of the surface, through the inner volume, thereby interacting with the flavoring material, and through the second part of the surface into the hole, in which the smoking article is arrangeable. The device includes the shape of a hollow cylinder having airflow-permeable inner and outer lateral areas.

A smoking article filter includes a recess to receive a filter insert unit. The filter insert unit is secured to the filter once inserted. The filter and the filter insert unit may include additives such as flavourants, colourants or sorbents.

A tobacco smoke filter or filter element comprising a stiff outer wrapper engaged around a downstream thermoformed core of tobacco smoke filtering material and a further core longitudinally aligned therewith; the downstream thermoformed core having a profiled outer surface which defines with the stiff outer wrapper at least one longitudinally extending channel which extends the length of the downstream core.

A smoking product includes: a smoking material portion which is wrapped by a smoking material wrapper; a filter portion whose upstream end portion is combined with the smoking material portion, which includes a capsule containing a flavoring, and which is wrapped by a filter wrapper; and a tipping wrapper which surrounds at least a partial region of the smoking material portion and the filter portion so that the smoking material portion and the filter portion are combined, wherein the tipping wrapper includes a first perforation region including a plurality of perforations formed along an outer circumferential surface of the tipping wrapper and a second perforation region including a plurality of perforations formed downstream of the first perforation region and along the outer circumferential surface of the tipping wrapper, and the capsule is disposed downstream of the first perforation region and upstream of the second perforation region.

A method for administering tetra-hydrocannabinol in a smokable tobacco product, the method includes providing the smokable tobacco product. The smokable tobacco product is impregnated with an extract of tetra-hydrocannabinol for administering the tetra-hydrocannabinol extract along with fumes from burning tobacco in the smokable tobacco product to a user.

The present invention relates to an article (10). The article comprises an aerosol-generating substrate (12) and a region (14) positioned longitudinally relative to the aerosol generating substrate. The region comprises a rod segment (16) formed from a plurality of elongate strips (17) of sheet material (18) extending longitudinally through said rod segment. The present invention also relates to a segment of sheet material for a rod segment. The segment of sheet material comprises a segment of a web (44) of sheet material (18) of discrete length comprising a plurality of elongate strips (17) and a band (22) of sheet material extending transversely to the plurality of elongate strips. The plurality of elongate strips extend from the band of sheet material. The present invention also relates to an apparatus (40) for manufacturing rod segments and a method of forming a rod segment.

The filter using technology for reducing the smell of tobacco smoke on hands, according to one embodiment of the present invention, comprises: a filter unit for filtering tobacco smoke, the filter unit being coupled to a tobacco shred; and filter-wrapping paper for wrapping the filter unit. The filter unit or the filter-wrapping paper may contain a material for reducing the smell of tobacco smoke. According to the embodiment of the present invention, green tea extracts containing catechin or other materials for reducing the smell of tobacco smoke, e.g. citric acids, glycerols, tannic acids and the like can be added to a tobacco filter to remove the smell from tobacco smoke generated during smoking, thus significantly lowering the strength of the smell of tobacco smoke on the hands of a smoker as compared to conventional tobacco filters.

A filter for sorption of components of tobacco smoke which are harmful to health comprises ceramic particles bonded to form a porous structure (12). In order to avoid contamination within a short period of time even when the filter is not properly disposed of, and without causing a loss in sorption or in the smoking sensation, the filter has decreasing water solubility from a tobacco-side portion (1) to an opposite mouth-side portion (2).

The method for manufacturing a wrapped endless rod of substantially flat continuous material comprises the steps of providing a substantially flat continuous material, treating the substantially flat continuous material with corona discharge and forming the corona treated substantially flat continuous material into an endless rod. Further steps comprise providing a wrapper, applying adhesive to the wrapper and wrapping the endless rod with the wrapper. Therein the step of applying adhesive to the wrapper comprises applying adhesive over a width of the wrapper and in a central portion of the wrapper.
