A sheet is provided, including a fibrous material, one or more nicotine salts, and sugar, at least about 20% by weight of the one or more nicotine salts being monoprotic.

A smoking article includes a mouth end portion in fluid communication with an aerosol generating cartridge. The cartridge includes an enclosure configured to receive an aerosol precursor therein, with the aerosol precursor being configured to generate an aerosol in response to heat. At least a portion of the enclosure is permeable such that the aerosol precursor is retained within the enclosure while the aerosol formed from the aerosol precursor is released from the enclosure through the permeable portion upon heating of the enclosure or the aerosol precursor therein.

A rod for use in a smoking article comprises a gathered sheet of homogenised tobacco material circumscribed by a wrapper. The sheet of homogenised tobacco material may comprises one or more aerosol-formers and have an aerosol former content of greater than 5% on a dry weight basis or of between 5% and 30% by weight on a dry weight basis. The rod may comprise a continuous element to which one or more additives have been applied, which is incorporated into the gathered continuous sheet of homogenised tobacco material. A method of forming the rod comprises the steps of: providing a continuous sheet of homogenised tobacco material; gathering the continuous sheet of homogenised tobacco material transversely relative to the longitudinal axis thereof; circumscribing the gathered continuous sheet of homogenised tobacco material with a wrapper to form a continuous rod; and severing the continuous rod into a plurality of discrete rods. The sheet of homogenised tobacco material is preferably crimped or otherwise textured.

The invention provides a method for making a fuel element for a smoking article comprising forming a combustible carbonaceous material into a fuel element adapted for use in a smoking article; incorporating a metal-containing catalyst precursor into the fuel element or onto the surface thereof to form a treated fuel element, the incorporating step occurring before, during, or after said forming step; and optionally heating or irradiating the treated fuel element at a temperature and for a time sufficient to convert the catalyst precursor to a catalytic metal compound. Examples of metal-containing catalyst precursors include iron nitrate, copper nitrate, cerium nitrate, cerium ammonium nitrate, manganese nitrate, magnesium nitrate, and zinc nitrate. Fuel elements treated according to the invention, and smoking articles including such fuel elements, are also provided.

Pellet substrates configured for use with a vapor delivery device to vaporize and deliver an aerosol to a user include a semi-porous base material formed of activated alumina pellets, activated carbon pellets, hulled millet grains that have a generally rounded shape or cellulose paper that has a generally disc shape. The pellet substrates are formed by mixing the base material with a liquid solution of an aerosol former and at least one of a tobacco extract mixture and a tobacco powder blend until the liquid solution is absorbed onto the exposed surfaces of the base material with or without drying by applying heat. The base material may be coated with a liquid hydrocolloid gum solution, namely a water soluble gum, such as sodium carboxymethyl cellulose, and distilled water to reduce fracturing, cracking, chipping and dusting of the pellet substrates.

A sheet is provided including a cellulosic material including cellulose powder, a weight ratio of cellulose powder to total cellulosic material in the sheet on a dry weight basis being greater than about 1:2; and one or more nicotine salts, at least about 20% by weight of the one or more nicotine salts being monoprotic.

The capsule includes the matrix with one or more portions of a filler material. The filler material is a plant-based cellulose material. The one or more portions define interstices. A containing structure contains the matrix. A consumable substance is infused within the filler material. The consumable substance is nicotine, a flavorant, a pre-aerosol formulation, a combination thereof, or a sub-combination thereof. The device includes a heating section with the capsule.

The present simulated smoking device may be used to produce vapor from a vapor-producing material for inhalation. The device may include a heating module with a first portion adapted to contain a first material, which is a vapor-producing material that produces vapor in response to heat, and a second portion that includes a heat-producing material capable of undergoing an exothermic chemical reaction, thereby transferring heat to the first portion. The device may include a first channel through which air may enter the first portion, a second channel through which vapor may exit the first portion, and an aperture or mouthpiece through which a user may inhale the vapor.

The invention relates to a method for manufacturing multi-component aerosol forming articles, each aerosol forming article defining a longitudinal axis and comprising N components serially juxtaposed along the longitudinal axis, where N is an integer2, the method comprising: providing transporting means for transporting components of aerosol forming articles in a transporting direction, said transporting means defining seats along said transporting direction; supplying seats of said transporting means with a first component for each aerosol forming article by positioning said first components one after the other along the transporting direction with their longitudinal axis parallel one to the others; checking each seat for the presence of said first component; adjoining a second component to the first component in a lengthwise axial manner in a given seat only if the first component is present in said given seat.

A heated aerosol-generating article is provided, including an aerosol-generating substrate, the aerosol-generating substrate including a homogenised botanical material comprising particulate plant material, an aerosol former, and a basic pH modifier; and the homogenised botanical material has a particulate plant material content of greater than or equal to about 60% by weight on a dry weight basis and less than or equal to about 90% by weight on a dry weight basis; and the homogenised botanical material has a pH greater than or equal to about 6.0 and less than or equal to about 8.0.
