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 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.

Cigarettes and filter subassemblies with squeezable flavor capsules and methods of manufacture

A cartridge for an e-vaping device enables separate vapors to be formed proximate to separate, respective ends of the cartridge. The cartridge includes multiple reservoirs and separate vaporizer assemblies coupled to separate reservoirs on opposite ends of the reservoirs. The separate reservoirs may hold separate pre-vapor formulations. The separate vaporizer assemblies may draw separate pre-vapor formulations from separate reservoirs towards opposite ends of the cartridge and vaporize the separate pre-vapor formulations via operation of separate heaters proximate to the separate ends. The separate heaters may be independently controlled to independently control vapor formation at the separate ends. The heaters may be controlled to independently control vapor formation rates proximate to the separate ends. The heaters may be controlled to form separate vapors at least one of simultaneously, concurrently, and at different times.

The use of pectins and/or polymers to prevent nicotine oxidation in tobacco containing products is disclosed. These polymers may be naturally occurring anionic polymers or synthetic polymers. These pectins and/or polymers prevent nicotine from oxidizing into cotinine, nicotine-cis-N-oxide, nicotine-trans-N-oxide, and/or nicotine-1,1-di-N-oxide. Molluscicides, algaecides, pesticides, and stabilized nicotine compositions comprising nicotine and pectin, anionic polymers, or combinations thereof are disclosed.

Use of pectin or other anionic polymers in the stabilization and controlled release of nicotine in oral sensorial tobacco products or nicotine containing non-tobacco oral sensorial products

An oral product includes a body that is wholly receivable in an oral cavity. The body includes a polymer matrix and one or more flavorants and/or active ingredients embedded in the polymer matrix. The polymer matrix can include a copolymer of ethylene and one or more vinyl monomers or zein. For example, the polymer can be ethylene-vinyl acetate copolymer and/or ethylene-vinyl alcohol copolymer. In some cases, the oral product can include tobacco and/or nicotine.

Soft oral product

Tobacco products comprising smokeless tobacco products and active ingredients, including those that antagonize nicotinic acetylcholine receptors, the TRPV1 channel, and/or the TRPA1 channel are disclosed. Nicotine replacement therapies comprising active ingredients, including those that antagonize nicotinic acetylcholine receptors, the TRPV1 channel, and/or the TRPA1 channel. The active ingredient may reduce or eliminate sensory irritation arising due to use of the product. Analgesic compositions comprising active ingredients. Methods of reducing taste and sensory irritation by employing an active ingredient.

Modifying taste and sensory irritation of smokeless tobacco and non-tobacco products

A cartridge for an e-vaping device includes a reservoir configured to hold pre-vapor formulation, a vaporizer assembly configured to draw at least some of the pre-vapor formulation from the reservoir and vaporize the drawn pre-vapor formulation to form a vapor, and a superabsorbent polymer configured to absorb free water from pre-vapor formulation held in the reservoir. The superabsorbent polymer includes a cross-linked polyacrylate copolymer that is substantially inert to the pre-vapor formulation. The superabsorbent polymer may be included in a layer on one or more surfaces in the cartridge. The layer may include the superabsorbent polymer and a binder. The superabsorbent polymer may be included with the pre-vapor formulation in a formulation mixture. The superabsorbent polymer may be included in an interior of at least one element comprising the cartridge. The superabsorbent polymer may be included in a separate compartment in the reservoir.

Encapsulated tobacco beads and processes of making the encapsulated tobacco beads are disclosed. According to an embodiment, a process of making encapsulated tobacco beads comprises mixing tobacco particles and menthol in an aqueous solution to form a wet mass; extruding the wet mass to form extrudates; spheronizing the extrudates to form tobacco beads; drying the tobacco beads; contacting the beads with a solution comprising a cation; and introducing the contacted tobacco beads into a solution of coating material in a concentration effective to induce ionic gelation of the coating material around the beads, to form encapsulated tobacco beads having gel coatings. According to another embodiment, an encapsulated tobacco bead comprises a core comprising tobacco particles and encapsulated menthol, an inner coating layer comprising hydroxypropyl methylcellulose or pectin, and an outer coating layer comprising an ionically-crosslinked gel.

Controlled release mentholated tobacco beads

Example embodiments relate to a method of protecting a surface of an e-vaping device portion from corrosion, the method including preparing a coating mixture configured to protect the surface from corrosion, and coating the surface with a protective coating based on the coating mixture, wherein the coating is performed via one of electrodeposition, dipping, spraying, and vapor deposition, and the coating mixture includes at least one of a silane and a resin.

Corrosion-resistant reservoir for an e-vaping device and method of manufacturing thereof

An electronic smoking article includes a reservoir including a liquid aerosol formulation, a heater operable to at least partially volatilize the liquid aerosol formulation and form an aerosol and a spiral path insert including a channel having a spiral configuration along an outer periphery of the spiral path insert. A coating can be applied to the outer periphery of the spiral path insert.

A sensor apparatus may include a conduit structure including an inner surface defining a conduit extending through an interior of the conduit structure, an inlet structure coupled to an end of the conduit structure, and a plurality of sensor devices in hydrodynamic contact with the conduit. The inlet structure may couple with an outlet end of an external tobacco element to hold the outlet end of the external tobacco element in fluid communication with an inlet opening of the conduit structure, such that the conduit structure may receive a generated aerosol from the external tobacco element at the inlet opening, and draw an instance of aerosol through the conduit towards an outlet opening. The instance of aerosol may include at least a portion of the generated aerosol. Each sensor device may generate sensor data indicating a pressure of the instance of aerosol through a separate portion of the conduit.

Sensor apparatuses and systems

A cartridge for an e-vaping device enables simultaneous vaporization of different pre-vapor formulations to form a vapor for vaping by an adult vaper.
