A smoking article is described in which the smoking article comprises tobacco material wrapped in a paper wrapper to form a tobacco rod, and wherein the paper wrapper has a diffusivity of between about 0.1 cm/s and 0.5 cm/s and a permeability of less than about 15 CU, and a method of manufacturing the smoking article is described.

An aerosol generating article includes a first portion including an organic acid, a second portion including a nicotine freebase, a third portion including a cooling material, and a fourth portion including a filter material, wherein a nicotine salt is generated through an acid-base reaction of the organic acid and nicotine freebase that are vaporized by heating.

An aerosol generating article is provided, including a combustible carbonaceous heat source; an aerosol-forming substrate; and a thermal indicator provided on an outer surface of the aerosol-generating article downstream of the combustible carbonaceous heat source. The thermal indicator includes at least one reversible thermochromic material that undergoes a first reversible visible colour change when a temperature of the thermal indicator rises to a first switching temperature and a second reversible visible colour change when a temperature of the thermal indicator falls to a second switching temperature. The first switching temperature is below about 80° C. and the second switching temperature is lower than or equal to the first switching temperature.

The hybrid aerosol-generating element for use in an aerosol-generating article includes a liquid retention material for holding an aerosol-forming liquid and a solid aerosol-forming substrate arranged next to the liquid retention material. The liquid retention material may entirely surround the solid aerosol-forming substrate. An aerosol-generating system utilizes the hybrid aerosol-generating element.

Delivery of additives in a smoking article is provided through thermally degradable, robust immobilized additive inserts. Additives can be immobilized in an elongated device or an insert, wherein the elongated device or the insert is sufficiently robust to allow the elongated device or the insert to be manually or machine inserted into a smoking article while maintaining the structure of the elongated device or the insert. By providing additives in the form of thermally degradable immobilized additive inserts, migration and/or loss of the additives in a smoking article prior to smoking can be reduced.

An edible mouthpiece system for use with a smokable item (e.g., a cigar, a cigarette, a pre-roll cone, an empty cone, a pre-rolled or hand-rolled cigarette, etc.) is provided. The edible mouthpiece may generally comprise candy (e.g., hard candy, chewing gum, etc.), or other types of edible materials. During use, the edible mouthpiece is coupled with the mouth end of a smokable item, comes into physical contact with the user's mouth, and provides flavoring thereto to enhance the smoking experience. Smoke from the smokable item also may be enhanced with flavor while passing through an inner passageway within the mouthpiece to the user's mouth.

An inductively heatable aerosol-forming rod for an aerosol-generating article is provided, including: at least one cylindrical core portion including at least one of a first aerosol-forming substrate and a first flavoring material; a first elongate susceptor laterally abutting the core portion at a first side along a longitudinal axis of the rod; a second elongate susceptor laterally abutting the core portion at second side along the longitudinal axis opposite to the first side such that the core portion is sandwiched between the first and the second susceptors; and a sleeve portion arranged around the core portion and the first and the second susceptors, the sleeve portion including at least one of a filler material, a second aerosol-forming substrate, and a second flavoring material. A shaping device for manufacturing of the inductively heatable aerosol-forming rods is also provided.

An inductively heatable aerosol-forming rod for an aerosol-generating article is provided, including one cylindrical core portion including a first aerosol-forming substrate; at least one elongate susceptor laterally abutting the cylindrical core portion in a non-bonded manner along a longitudinal axis of the aerosol-forming rod; and a sleeve portion arranged around the cylindrical core portion and the susceptor, the sleeve including at least one of a filler material and a second aerosol-forming substrate. A shaping device for manufacturing the inductively heatable aerosol-forming rods is also provided, the shaping device including a core-forming device, a sleeve-forming device, and a longitudinal guide.

A method of manufacturing a smoking article including a tube filter includes preparing a smoking material portion, a first tube filter flavored by a first flavoring liquid, and a mouthpiece flavored by a second flavoring liquid; and combining and packaging the smoking material portion, the first tube filter, and the mouthpiece with a wrapper, wherein the preparing comprises applying the first flavoring liquid inside the first tube filter through a hollow of the first tube filter.

A wrapping material for a smoking article is formed from a web that includes extracted pieces of cocoa husk combined with web building fibers. The web has a basis weight of from about 20 gsm to about 80 gsm and a permeability of from about 10 Coresta to about 100 Coresta. The wrapping material has a pleasant and neutral smell and taste. The wrapping material is tobacco and nicotine free and can be used as a carrier for flavorings or aerosol delivery agents.
