A smoking article assembly (100) comprising a smoking article (80), and a tube (10) for temporary affixment to the smoking article. The smoking article comprises a tobacco rod, and a mouthpiece comprising a filter and a tipping wrapper, the tipping wrapper circumscribing the filter and attaching the filter to the tobacco rod. The tube is configured to be disposed around at least a portion of the mouthpiece such that the tube is slidable over the outer surface of the tipping wrapper. The tube comprises 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 coefficient of static friction between the inner surface of the tube and the outer surface of the tipping wrapper may be between about 0.5 and about 0.9. The lumen may be substantially cylindrical and have a diameter that is between one percent and four percent greater than the average diameter of the smoking article mouthpiece.

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.

A vapour generating includes a main body having a first end and a second end opposite the first end, the body arranged to contain a solid vapour generating material; a filter having a mouthpiece end and an attachment end opposite the mouthpiece end, the attachment end arranged to be attached to the first end of the main body; and an airflow passageway within the filter configured to allow a vapour to flow into the filter through the attachment end from the first end of the body and out of the filter through the mouthpiece end. The filter includes an adjuster configured to adjust the length of the airflow passageway.

An inhalation device to hold an inhalant-generating component to generate an inhalant to be drawn through the device and inhaled by a user. The device has a body (10) having a first open end (11b) configured to receive an inhalant-generating component and, a second open end (11a) in fluid communication with the first end through which a user may draw inhalant from the inhalant-generating component. The body is configured to receive a flavour delivery component (63) having an organoleptic material to selectively allow or prevent addition of an organoleptic additive into an inhalant stream drawn through the device. The device includes a ventilation control mechanism (15) configured to selectively allow different amounts of ambient air into the body to mix with and dilute the inhalant stream as it is drawn through the device in use.

The invention relates to a smoking article (10) comprising a tobacco rod (12) and a filter, the filter comprising a filter unit (14) comprising a first segment (16) of filtration material; a second segment comprising a tubular element (18) of filtration material upstream of the first segment (16), the tubular element (18) having an outer diameter (D2) and an inner diameter (D1). An inner surface of the tubular element (18) is substantially air impermeable. The second segment further comprises a frangible or irreversibly collapsible flow restrictor (24) disposed in the tubular element (18). When the flow restrictor (24) is in a substantially unbroken or non-collapsed state, the filter unit (14) has a first RTD. When the flow restrictor (24) is broken or collapsed, the filter unit (14) has a second RTD, the second RTD being smaller than the first RTD.

A smoking article (130) comprises a variable flow system configured to vary gaseous flow into or through the smoking article.

There is provided an aerosol-generating article (10) comprising an aerosol-generating substrate (12) and a mouthpiece (14) secured to a downstream end of the aerosol-generating substrate (12). The mouth piece (14) comprises at least one segment of porous filter material (20) and a blocking segment (27) that impedes air flow downstream of the at least one segment of porous filter material (20). The blocking segment (27) comprises a segment of support material (22) having an annular shape defining a channel (24) extending through at least part of the segment of support material (22), and at least one freshener delivery element (26) contained within the channel (24). The blocking segment (27) comprising the at least one freshener delivery element (26) is detachable from the at least one segment of porous filter material (20) to decrease the resistance to draw of the aerosol-generating article (10).

A filter for a tobacco product provided with a through hole along the axial direction, including a slit on a circumference of the filter along a circumferential direction, wherein a cross-sectional area of the through hole is changed by twisting both sides in the axial direction of the filter in relatively opposite directions along the circumferential direction with the slit as a boundary. A tobacco product further has the above filter, tip paper that wraps at least a part of the filter; and a tobacco rod including shredded tobacco and connected to the filter through the tip paper.

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 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.
