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.

A smoking article comprising one or more rod articles, an inner layer extending around the rod articles, and an outer layer extending around the inner layer. The inner and outer layers are integrally formed. The outer layer comprises a selection portion configured to move over an underlying part of the inner layer to select a property of the smoking article.

A smoking article comprises a first part and a second part movable relative to the first part. A control mechanism comprises a first control surface on one of the first part or second part; and a second control surface on the other of the first and second parts. The second control surface is configured to engage with the first control surface to control relative rotation between the first part and second part.

A smoking article comprising a first part moveable relative to a second part, and an indexing mechanism comprising a first indexing surface on the first part, and a second indexing surface on a support element of the second part. The second indexing surface is configured to engage with the first indexing surface to control relative movement between the first part and second part. One or more spacer elements are arranged to control a radial position of the first indexing surface relative to the second indexing surface. The support element and one or more spacer elements are frangibly connected.

The present invention relates to a smoking article having a movable vapour release portion to allow the vapour release portion to be isolated from, or exposed to, a smoke pathway. The invention also relates to a method of manufacturing such smoking articles. In particular, there is provided a smoking article comprising a first segment, a second segment, and an aerosol generating substrate coupled to the first and second segments. At least one of the first and second segments comprises a vapour release portion, whereby the first and second segments are movable relative to each other from a first configuration to a second configuration, whereby in the first configuration the vapour release portion is substantially isolated from an airflow pathway and in the second configuration the vapour release portion is exposed to the airflow pathway.

A smoking article, a smoking article assembly, a blank for forming a smoking article, and a method of manufacturing a smoking article. A smoking article comprising one or more rod articles, an inner layer extending around the rod articles, and an outer layer extending around the inner layer. The inner and outer layers are integrally formed. The outer layer comprises a selection portion configured to move over an underlying part of the inner layer to select a property of the smoking article.

A cooling assembly for the aerosol-generating article according to an embodiment may include a cooling rod for cooling an aerosol generated by the aerosol-generating article; a perforation formed in the cooling rod and through which air passes; and an air volume regulator disposed on the outside of the cooling rod to cover the perforation, and regulating an amount of air passing through the perforation as the air volume regulator moves from one position to another.

A reusable modular smoking filtration apparatus includes a tip having a tubular shape with a first end configured with a first coupling feature and a second end configured with a second coupling feature, a removable freshness plug configured to be coupled to the first coupling feature, and a removable cross-hair shaped filter configured to be coupled to the second coupling feature.
