The present disclosure relates to reservoirs for storing products in electronic smoking articles. The reservoir is manufactured from cellulose acetate fiber, thermoplastic fiber, non-thermoplastic fiber, or a combination thereof. The reservoir is substantially tubular in shape and is adapted to accommodate internal components of the smoking article thereby increasing reservoir capacity. The internal components particularly can comprise an atomizer, which may include a braided wick.

Electronic smoking article with improved storage and transport of aerosol precursor compositions

An apparatus and method for forming a smoking article rod is provided. A forming device is configured to engage a continuous stream of a smokable filler material with a first surface of a longitudinally-continuous web of a wrapping material, the web having first and second edge portions extending along the web, and a second surface opposing the first surface. A wrapping device is configured to longitudinally overlap the first and second edge portions such that the first surface about the first edge portion extends over the second surface about the second edge portion, to contain the smokable filler material within the web. An adhesive applicator device is configured to apply an adhesive material to the second surface about and longitudinally along the second edge portion, between the overlapped edge portions, prior to the wrapping device engaging the overlapped edge portions, with the adhesive material therebetween, to form a sealed seam.

Seam-sealing adhesive application apparatus and associated method

A pouched product adapted for release of a releasable component therefrom is provided herein. The pouched product can include a water-permeable fabric pouch formed so as to define a cavity therein, and a composition contained within the cavity of the water-permeable fabric pouch, the composition including one or more releasable components that are released from the composition under mouth conditions and that are capable of movement through the water-permeable fabric pouch. The composition includes nicotine and at least one particulate non-tobacco material. The pouched product also includes at least one capsule contained within the cavity of the water-permeable fabric pouch, the capsule having a capsule wall surrounding an inner payload comprising at least one botanical.

Capsule-containing pouched product for oral use

Methods for producing dissolving grade pulp and microcrystalline cellulose from tobacco are provided. The methods include chemical pulping a tobacco input to form a tobacco pulp. Chemical pulping the tobacco input includes combining the tobacco input with a strong base defining a weight from about 5% to about 50% of the tobacco input, and heating the tobacco input and the strong base with an H-factor from about 500 to about 3,300. Further, the methods include bleaching the tobacco pulp to produce a dissolving grade pulp. Bleaching the tobacco pulp may include chlorination of the tobacco pulp with a chlorine dioxide solution, and caustic extraction of the tobacco pulp with a second strong base. A related tobacco-derived microcrystalline cellulose product is also provided, which can be used as a binder, a filler, and/or a texturizer in a tobacco product, such as a smokeless tobacco product.

Method for producing microcrystalline cellulose from tobacco and related tobacco product

A filtered cigarette possesses a smokable rod and a filter element. The smokable rod is secured to the filter element using tipping material. The cigarette possesses more than one layer of tipping material. An outer layer of tipping material can overlie at least a portion of an underlying inner layer of tipping material, and during use by the smoker, the outer layer can be removed from the cigarette. Thus, it is possible for a cigarette manufacturer to provide a cigarette that can be used as such by the smoker, or that can be adapted by the smoker to provide a different sensory experience (e.g., the visual, organoleptic, trigeminal, aromatic, and tactile characteristics of the cigarette can be altered by removal of the outer tipping material). Alternatively, the use of the outer layer of tipping material can be used to improve the physical integrity of the cigarette.

Filtered cigarette possessing tipping material

Cigarettes are manufactured using modified automated cigarette making apparatus. Those cigarettes possess smokable rods having wrapping paper having additive materials applied thereto as patterns. The additive materials, which can include a starch and/or a polymer, are applied to a continuous paper web either online or offline the cigarette making apparatus. The formulation can be applied to the paper web using application apparatus possessing a series of rollers. In particular, a wrapping paper for a smokable rod can include a pattern of bands having a water-insoluble material comprising a starch ester, a starch-coated inorganic filler, and/or a thermoplastic polymer in an amount such that the material is sufficiently deformable so as to (a) reduce an amount of pressure to apply the bands, (b) decrease paper diffusivity, and (c) maintain paper opacity at a level acceptable for commercial production of the smokable rods.

Materials, equipment, and methods for manufacturing cigarettes

A filtered smoking article is provided, which includes a tobacco-containing rod surrounded by a wrapping material; a filter element surrounded by a plug wrap adjacent to the tobacco-containing rod; and a tipping material securing the tobacco-containing rod to the filter element, the tipping material overlying the plug wrap of the filter element and a portion of the wrapping material of the tobacco-containing rod, wherein at least one of the plug wrap, the tipping material, and the wrapping material surrounding the tobacco-containing rod are secured by an adhesive composition comprising a thermoplastic starch polymer. The adhesive composition can include a blend of the thermoplastic starch polymer with a second biodegradable polymer, such as polyvinyl alcohol, aliphatic polyesters, aliphatic polyurethanes, cis-polyisoprene, cis-polybutadiene, polyhydroxy alkanoates, polyanhydrides, and copolymers and blends thereof.

Degradable adhesive compositions for smoking articles

Smokable rods of cigarettes are manufactured using wrapping materials that incorporate at least one fibrous material (e.g., flax fibers, hardwood pulp fibers and/or softwood pulp fibers) at least one filler material (e.g., calcium carbonate in particulate form). The wrapping materials possess multi-layer coatings. The wrapping materials possess coatings in the form of series of spaced apart bands, each band possessing a series of layers. At least one of the coating layers can have a filler material dispersed or suspended within a film-forming material of that layer.

Wrapping materials for smoking articles

Smokable rods of cigarettes are manufactured using wrapping materials that incorporate at least one fibrous material (e.g., flax fibers, hardwood pulp fibers and/or softwood pulp fibers) at least one filler material (e.g., calcium carbonate in particulate form). The wrapping materials possess multi-layer coatings. The wrapping materials possess coatings in the form of series of spaced apart bands, each band possessing a series of layers. At least one of the coating layers can have a filler material dispersed or suspended within a film-forming material of that layer. For a representative wrapping material, a pattern of applied to the wire side major surface of the wrapping material substrate as a plurality of layers, and at least one of the layers includes ethylcellulose and calcium carbonate. For that layer, the calcium carbonate is present in an amount greater than the ethylcellulose, on a weight basis. The ethylcellulose and calcium carbonate typically are applied as part of a non-aqueous formulation incorporating iso-propyl acetate, triacetin and lecithin.

Cigarettes which yield low levels of visible sidestream smoke upon use employ a paper wrapping material having about 30 weight percent calcium carbonate and about 70 weight percent flax. The paper wrapper includes a coating or a film of polymeric material and an organic filler material. A preferred polymeric material is nitrocellulose, and a preferred inorganic filler material of the coating is particulate magnesium hydroxide. The coating weighs about 0.05 to about 0.5 pound per 3,000 square feet of wrapping material.
