A filtered cigarette possesses at least one breakable capsule in its filter element. The filter element can possess a central cavity extending from the cigarette tobacco rod towards the middle of the filter element. The central cavity may be defined by an inner filter portion. The inner filter portion can be surrounded by an outer filter portion comprised of filter tow material that is generally permeable to the smoke generated by the cigarette. At least one breakable capsule is disposed in the central cavity of the filter element. The breakable capsules are spherical in shape, and are composed of a gelatin outer shell that encloses a payload of triglycerides and flavoring agents. The breakable capsules are adapted to rupture in response to pressure applied by the smoker to the outside region of the filter 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.

Disclosed are fibers which contain identification fibers. The identification fibers can comprise one or more chemical markers, or taggants, which may vary among the fibers or be incorporated throughout all of the fibers. The disclosure also relates to the method for making and characterizing the fibers. Characterization of the fibers can include identifying chemical markers and correlating the chemical markers and a taggant chemical marker amounts of at least one of the chemical markers to manufacturer-specific taggants to determine supply chain information. The supply chain information can be used to track the fibers from manufacturing through intermediaries, conversion to final product, and/or the consumer.

An object of the present invention is to provide a cellulose acetate composition with excellent biodegradability and water solubility, and excellent thermoformability. A cellulose acetate composition comprising: a cellulose acetate having a degree of acetyl substitution of 0.4 or greater and less than 1.4; and a citrate ester-based plasticizer, wherein a content of the citrate ester-based plasticizer is 3 parts by weight or greater per 100 parts by weight of the total amount of the cellulose acetate and the citrate ester-based plasticizer.

The embodiments herein provide a filter for cigarette comprising graphene nano-composite based material enclosed in a casing. The filter is reusable and is plugged to any cigarette, or tobacco smoking products. The filter is a stand-alone product or manufactured integrally with each individual cigarette. The filter provides a safe smoking option to tobacco smokers without changing their smoking habits by reducing the tar content and other toxic chemicals in the inhaled smoke. The graphene based nanocomposite filter adsorbs the toxic agents from the smoke of cigarette, beedi, hookah. The filter is fabricated by treating ceramic particles and coating them with carbon particles. The carbon particles are carbonized. The ceramic particles coated with carbon are segregated based on shape and size and treated chemically to convert carbon into graphene under inert conditions. The graphene coated particles are chemically functionalized for improved filtration.

There is provided a smoking article having an aerosol generating substrate and a mouthpiece. The mouthpiece includes a cavity at least partially filled with a particulate material, such as activated carbon,and contains at least one breakable capsule of a liquid flavourant at least partially surrounded by the particulate material, such that the force required to break the capsule within the mouthpiece to release the liquid flavourant is less than three times the inherent burst strength of the capsule.

A method of preparing an additive assembly for insertion into tobacco industry product filter tow, comprising: providing a web comprising an array of discrete portions of additive disposed in or on the web, the array comprising columns of at least two discrete portions of additive across a width of the web; and forming a chain of discrete portions of additive in the web. The chain comprises: connecting portions that connect adjacent discrete portions of additive in a column of the array; and connecting portions that are configured to be nonlinear to connect discrete portions of additive in respective adjacent columns of the array.

A universal filtering mouthpiece for smoking devices comprising a flexible and substantially conical shaped body having a small diameter end and a large diameter end; a hollow smoke passage which runs axially through the conical shaped body from the small diameter end to the large diameter end; a filter cartridge housing centered axially at the mouthpiece end of the said flexible and substantially conical shaped body which communicates with the hollow smoke passage and capable of housing a removable filter; and a disposable, high-airflow filter cartridge consisting of a rigid cylindrical frame having rounded edges, the rigid cylindrical frame housing a smoke filter inside the inner diameter of said rigid cylindrical frame. The universal filtering mouthpiece for smoking devices is readily implementable across a wide variety of smoking devices such as, but not limited to, pipes, bongs, hookahs, water pipes, electronic cigarettes, cigarettes, and pre-roll cigarettes.

Improved delivery of additive materials to cigarettes is provided through the use of one or more capsules containing additive materials, such as flavor components, in the filter section of a cigarette. The capsule or capsules are provided between first and second absorbent members and the capsules are subjected to an external force, such as squeezing, by a smoker prior to or during smoking of the cigarette in order to release at least a portion of the additive material and expose the additive material to mainstream smoke passing through the filter. The capsules provide a barrier between the additive materials and other cigarettes components, such as sorbents or filter materials, in order to reduce additive material migration into the other cigarette components prior to desired use. An outer cover which is impermeable to the fluid within the capsules is provided about the capsule or capsules and the first and second absorbent members.

A method of forming a carbon material from the stalk or roots of a plant of the Nicotiana species is provided herein, wherein the method includes i) receiving a tobacco material comprising at least one of a stalk material and a root material of a harvested plant of the Nicotiana species; and ii) pyrolyzing the tobacco material to remove volatiles and to form a tobacco-derived carbon material. Optionally, the method can further include activating the tobacco-derived carbon material. The tobacco-derived carbon material can be incorporated into a tobacco product. A carbon material derived from pyrolyzing a tobacco material in the form of at least one of a tobacco stalk material and a tobacco root material of a harvested plant of the Nicotiana species is also provided herein.
