A flow control device (14) for a smoking article (10) is provided. The device comprises first and second selector parts (18, 19) to control flow along a plurality of controllable flow channels.

The invention relates to a smoking article (120) comprising a smoking article rod portion (2) having a recess (13) and a mouthpiece (110) arranged to be attached to the smoking article. The mouthpiece comprises an elongate cylindrical element (20) having adjacent first and second portions each extending partially along the length of the cylindrical element, the first portion being arranged to be inserted into a smoking article recess by a user. The mouthpiece also comprises an annular element (111) arranged around the second portion of the cylindrical element, the annular element having a larger external diameter than the cylindrical element such that the annular element is larger than the diameter of the recess.

A smoking cartridge configured to removably engage with the bowl of a smoking apparatus comprises a receptacle, a sealing member, and an opening that comprises inwardly projecting flaps. The receptacle is configured to contain a smoking material. The sealing member is disposed along the periphery of the receptacle proximal to a lower portion of the receptacle. The sealing member is configured to removably engage and seal with the bowl of the smoking apparatus. The opening is disposed at a bottom of the receptacle, which is defined by inwardly projecting adjustable flaps. The flaps are configured to be adjustably bent to vary the size of the opening.

The invention discloses a variable-ventilation filter tip and a cigarette. The filter tip includes a filter element and a coating layer. The coating layer wraps the filter element. The filter element includes a smoke inlet end and a smoke release end. A phase-change ventilation area and a non-phase-change ventilation area are arranged on the coating layer, a plurality of first ventilation holes are arranged in the phase-change ventilation area, and a plurality of second ventilation holes are arranged in the non-phase-change ventilation area. Outside air penetrates through the coating layer through the first ventilation holes and the second ventilation holes to enter a part of the filter element. A part in the filter element close to the smoke inlet end is provided with a starch tube. A phase-change material is filled in the first ventilation hole. A phase-change temperature of the phase-change material ranges from 45° C. to 60° C.

A tube (10) for temporary affixment to a mouthpiece of a smoking article (80), the tube (10) comprising an open upstream end, an open downstream end, an outer surface, and an inner surface defining a lumen for receiving the mouthpiece of the smoking article, the lumen extending from the open upstream end to the open downstream end; the tube further comprising a first ventilation zone (50) for providing ventilation into the lumen of the tube, the first ventilation zone comprising a first line of perforation holes (52) circumscribing the tube at a location at least 10 mm from the open downstream end of the tube.

The present disclosure provides thermal energy absorbers for use in smoking articles. In an example embodiment, the smoking article may comprise an outer wrap circumscribing at least a portion of the smoking article, wherein the smoking article is defined by an upstream lighting end and a downstream mouth end, a carbon heat source positioned proximate the lighting end, a tobacco material positioned downstream of the carbon heat source and spatially separated from the mouth end of the smoking article, and a thermal energy absorber at least partially positioned between the tobacco material and the carbon heat source.

The invention relates to a smoking article comprising a smoking article rod portion having a recess and a mouthpiece attachable to the smoking article rod portion. The mouthpiece includes an elongate cylindrical element arranged to be inserted into the recess by a user. The cylindrical element comprises an outer surface having at least one circumferentially extending raised area, and the at least one circumferentially extending raised area is configured to engage with an inner surface of the recess to prevent or restrict air flow between the inner surface of the recess and an outer surface of the mouthpiece.

A smoking article or an aerosol generating product comprising a filter arrangement comprising a first filter section and a second filter section, the second filter section being located downstream of the first filter section; and a ventilation arrangement configured to provide a user controllable level of ventilation into the first filter section; wherein a resistance to gaseous flow through the length of the second filter section is lower than a resistance to gaseous flow through the length of the first filter section; and the first filter section comprising filter material and one or more capsules comprising an additive.

The invention relates to a smoking article (1) comprising a smoking article rod portion (2) having a recess (13) and a mouthpiece (81, 91, 101) attachable to the smoking article rod portion. The mouthpiece includes an elongate cylindrical element (20) arranged to be inserted into the recess by a user. The cylindrical element comprises an outer surface having at least one circumferentially extending raised area (83, 103), and the at least one circumferentially extending raised area is configured to engage with an inner surface of the recess to prevent or restrict air flow between the inner surface of the recess and an outer surface of the mouth piece.

The filter for cigarette product includes a mouthpiece end side-filter material and a front stage-filter material. The mouthpiece end side-filter material has a low air flow-resistance unit that is arranged in a part of a cross section from a front end surface to a rear end surface and having a relatively low air flow-resistance, and a high air flow-resistance unit that is arranged in the remainder of the cross section from the front end surface to the rear end surface and having a higher air flow-resistance than the low air flow-resistance unit. At least on the rear end surface of the mouthpiece end side-filter material, the low air flow-resistance unit is arranged only in one semicircular area, of two parts into which the cross section of the mouthpiece end side-filter material is divided.
