A smoking article comprises a tobacco rod and a filter connected to the tobacco rod. The filter comprises a first filter segment and a hollow tube segment downstream of the first filter segment. The hollow tube segment defines a cavity at the mouth end of the filter providing an unrestricted flow channel that extends from the downstream end of the first filter segment to the mouth end of the filter. The length of the hollow tube segment is at least about 25 percent of the overall filter length. Further, the smoking article comprises a ventilation zone comprising at least one circumferential row of perforations provided at a location around the first filter segment.

Smoking article with a mouth end cavity and ventilation

A smoking article includes a tobacco substrate and a mouthpiece axially aligned in an abutting end to end relationship with the tobacco substrate. Hydrophobic tipping paper is disposed about the mouthpiece. The tipping paper is hydrophobic due to hydrophobic groups covalently bonded to the tipping paper.

An aerosol generating article () comprises: an aerosol generating substrate (); a filter () in axial alignment with the aerosol generating substrate, the filter () comprising at least one water dispersible filter component (), wherein the filter component is water dispersible under the test conditions of EN 14987:2006; and a tipping wrapper () wrapped around the filter () and at least a portion of the aerosol generating substrate (). The tipping wrapper () comprises: a first weakening line () extending around at least a portion of the tipping wrapper (); a removable tipping wrapper portion () extending downstream from the at least one weakening line () and at least partially overlying the water dispersible filter component (); and an upstream tipping wrapper portion () extending upstream from the first weakening line (), wherein the upstream tipping wrapper portion () is attached to a downstream portion of the aerosol generating substrate () and an upstream portion of the filter ().

Aerosol generating article having water dispersible filter component

A smoking article () comprises a tobacco rod () and a filter () in axial alignment with the tobacco rod (). Tipping wrapper () circumscribes at least a portion of the filter () and at least a portion of the tobacco rod () to secure the filter () in axial alignment with the tobacco rod (). The filter () comprises a hollow tubular element () at the upstream end of the filter () adjacent to the tobacco rod () and a first segment of filtration material () downstream from and adjacent to the hollow tubular element (). The tipping wrapper () comprises a line of weakness () disposed at, or within 5 millimetres upstream of, the interface between the hollow tubular element () and the tobacco rod (). The tobacco rod (), the first segment of filtration material () and the inner surface of the hollow tubular element () together define a cavity (). The cavity () is designed to receive the lit end of the smoking article () and any unburnt tobacco material when the consumer chooses to extinguish the smoking article ().

Smoking article with improved extinguishment

There is provided a smoking article comprising a tobacco rod, a filter and tipping material attaching the tobacco rod and the filter. The filter comprises a plug of filtration material that defines a furthest downstream end of the smoking article, the plug being surrounded by one or more filter wrappers. The tipping material includes a ventilation zone. The tipping material and the filter wrapper or wrappers have a combined thickness (t) perpendicular to the longitudinal direction of the smoking article, and the smoking article, at a location about the plug of filtration material, has a diameter (D SA) perpendicular to the longitudinal direction of the smoking article. The diameter (D SA) to thickness (t) ratio is less than about 80 and the filtration material extends to the furthest downstream end of the smoking article.

Smoking article filter for easy extinguishing

An aerosol generating article () comprises: an aerosol generating substrate (); a mouthpiece (); and a tipping wrapper () comprising: a first weakening line () extending around at least a portion of the tipping wrapper (); a removable tipping wrapper portion () extending downstream from the first weakening line (); an upstream tipping wrapper portion () extending upstream from the first weakening line (); a first longitudinal edge () extending along the outer surface of the aerosol generating article; and a second longitudinal edge () opposed to the first longitudinal edge () and overlying the mouthpiece (). The tipping wrapper () overlaps itself in an overlapping region () extending at least 45 degrees circumferentially around the aerosol generating article (). The removable tipping wrapper portion () is adhered to itself by means of an area of adhesive () provided in the overlapping region () and positioned such that the removable tipping wrapper portion () comprises an adhesive free area () adjacent at least a portion of the first longitudinal edge ().

Aerosol generating article having modified tipping wrapper and removable tipping wrapper portion

A method of producing smoking articles, the method comprising a first step of providing a continuous array of first filter members (), second filter segments () and tubular members (). A tubular member () is provided between each pair of consecutive first filter members () and a second filter segment () is provided between each first filter member () and each tubular member (). Each second filter segment () contains one or more breakable capsules, wherein each breakable capsule comprises an outer shell and an inner core containing an additive. The continuous array of first filter members (), second filter segments () and tubular members () is then wrapped with a continuous sheet of plug wrap () to form a wrapped filter array, wherein the plug wrap () has a basis weight of less than 90 grams per square metre.
