A coaxial filter cigarette with a rod portion having an inner core of material glowing substantially free of residue, in particular tobacco material, a sheath or wrapper for the inner core, an outer shell of tobacco and/or non-tobacco material coaxially surrounding the inner core or its sheath, respectively, a sheath or wrapper for the outer shell, and with a filter portion having a filter core, an air-impermeable sheath or wrapper for the filter core, a filter shell and a sheath or wrapper for the filter shell comprises a zone of the main heat source which is located in the inner core of the rod portion and a zone in which the major part of the aerosol reaching the mouth of the smoker is produced and which is located in the outer shell of the rod portion; the filter portion greatly reduces the combustion gases originating from the inner core of the rod portion and substantially reduces the smoke particles originating from the inner core, whereas the aerosol produced in the outer shell of the rod portion is influenced only slightly or not at all.

Coaxial filter cigarette

A smokable article having an aerosol generating zone connected to a mouthpiece via a tubular intermediate zone, wherein the aerosol generating zone includes an annular combustion element and a cylindrical carrier for an aerosol precursor coaxially disposed therewithin with a space therebetween forming air flow passages. Heat from the combustion element conducted to the aerosol carrier generates aerosols that may be drawn by air passing through the air flow passages to the mouthpiece by a smoker.

Smokable article

The present invention relates to a smokable article which is intended to permit the smoker to avoid the condensates usually present in the smoke while retaining the taste experience familiar from conventional cigarettes; this is achieved in that a sheet-like carrier element coated with an aroma-carrying material and having a low thermal capacity is brought into direct thermal contact with a heat source comprising a hollow cylindrical combustion element having at least one passage therethrough wherein said passage is separate and distinct from the hollow portion; in the pauses between draws a cavity serves as collecting container or reservoir for the aromatic substances developed which can be inhaled in the next draw by the smoker.

A glue for sealing the side seams of smokable articles contains 5 to 40 percent by weight dry substance pectin in an aqueous dispersion; to produce this glue the aqueous dispersion of the pectin is prepared by charging the pectin portion-wise into heated, demineralized water, stirring the corresponding mixture and executing a chain decomposition of the pectin.

Glue and method for its production

A smokable article including an aerosol generating zone which has a combustion element and a carrier for an aerosol precursor which coaxially surrounds the combustion element, flow passages in the aerosol generating zone and a mouthpiece. The combustion element includes axial flow passages extending over its entire length and a jacket formed of a gas-impermeable heat-insulating material. The jacket is surrounded at a distance by a concentric sleeve of a gas-impermeable material so that between the jacket and the sleeve at least one flow space results; the sucked-in air flows through the flow passages in the combustion element, then back through the flow space between the jacket and the sleeve and finally through the carrier for the aerosol precursor to the mouthpiece. The carrier includes a precursor, and the combustion element has a plurality of axial passages.

The invention described here relates to a smokable article which is intended to enable the smoker to avoid the condensates usually present in the smoke while retaining or even enhancing the taste experience familiar from conventional cigarettes or smokable articles; this is achieved by the advantageous geometrical and thermodynamic configuration of the heat source.

A coaxial cigarette comprising an inner core of a material glowing away substantially without residue, in particular tobacco material, with a sheath for the inner core, an outer jacket coaxially surrounding the inner core and its sheath and comprising a tobacco and/or non-tobacco material, and a sheath for the outer jacket, has a diameter of the inner core which lies in the range from 45% to 80% of the outer diameter of the coaxial cigarette; the inner core has a packing density in the range from 300 to 400 mg/cm.sup.3 ; the outer jacket has a packing density in the rnage from 170 to 250 mg/cm.sup.3. The sheath of the inner core has an air permeability of less than 3 ISO units. The outer sheath has a front segment to be lit and a rear mouth-side segment; the front ignition-side segment of the outer sheath contains conventional glow salts and has an air permeability of 15 to 40 ISO units and the rear mouth-side segment of the outer sheath contains no glow salts and has an air permeability of less than 3 ISO units.

Coaxial cigarette

A filter tip for a smoking product comprised of a filter rod attached at one end to the smoking product. The filter rod is surrounded by a tip wrapping layer which terminates at a distance from the mouth end of the filter rod. The projecting end of the rod is tapered toward the mouth end. The taper causes smoke drawn through the filter tip to flow out obliquely with respect to the longitudinal axis of the smoking product.
