A product rod comprising a plurality of individual tobacco smoke filters or filter elements abutted end to end; and a wrapper engaged around the plurality of filters or filter elements, the wrapper including perforations.

The subject disclosure relates to a device for smoking and filtering smoke. In an aspect, the device can comprise an outer sleeve component, a detachable mouthpiece assembly, an ignition chamber assembly, and a detachable filtration assembly.

A method of fabricating a smoking article filter element includes arranging a corrugated laminate web around a portion of filter material having an elongate shape and a longitudinal axis, such that the grooves and ridges of the laminate web run in the same direction as the longitudinal axis of the filter material. A method of fabricating a smoking article involves the same method as that of fabricating a smoking article filter element.

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.

This disclosure provides tobacco plants containing a PMT RNAi and tobacco plants having a mutation in PMT, and methods of making and using such plants.

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 backing with corrugations on a first surface. The corrugations are parallel and each has an airspace along an entire longitudinal length. A second surface of the backing includes perforations or scores oriented perpendicularly or parallel to the corrugations. The corrugations or scores are fold lines or frangible tear lines. The airspaces may also include a filter material. The second surface of the backing may be adhered to a corner of a rolling paper on the surface but opposite edge as a gum strip. The corrugations are parallel to the gum strip.

An aerosol-generating article according to an embodiment of the disclosure includes: a tobacco rod having an outer circumferential surface surrounded by a wrapper; a filter rod having an outer circumferential surface surrounded by the wrapper, and including a segment including a structure supporting the wrapper in a transverse direction and at least one channel formed between the wrapper and the structure: and an airflow obstruction configured to obstruct an airflow of aerosol passing through the at least one channel.

One or more embodiments relate to a cellulose acetate tow, a filter including the same, and an aerosol generating article including the filter.

A tip device for an electronic vaping device may include a first conduit structure and a second conduit structure. The first conduit structure may be configured to direct a generated vapor through a first conduit. The second conduit structure may be configured to direct an air flow from an ambient environment through a second conduit. The second conduit structure may include an additive material on a surface of the second conduit structure, the additive material including an additive, the additive material configured to release the additive into the air flow directed through the second conduit. An interposing structure of the first conduit structure and the second conduit structure may physically isolate the additive material from the first conduit, such that the additive material is configured to release the additive into the air flow directed through the second conduit independently of the generated vapor directed through the first conduit.
