The present disclosure relates to compositions that are useful in the delivery of various materials. In particular, the compositions comprise a suspension wherein an internal phase material is surrounded by an external phase material. The internal phase specifically can be a hydrophilic material, and the external phase specifically can be a hydrophobic material. The materials are combined so that the internal phase is substantially encapsulated by the external phase such that release can be controlled in relation to osmotic pressure differentials. The suspension can be combined with a carrier, and various systems and products can be formed with the suspension and optional carrier, such as oral strips, spray delivery systems, smokeless tobacco products, aerosol delivery devices, cigarettes, and packaging.

This smoking article filter (4) has: a fine-powder-containing article (44) in which there is clumped together a raw powder that includes a taste component and/or an aroma component, the fine-powder-containing article being formed into a fine powder by the application of an external force; a cavity (43) in which the fine-powder-containing article is disposed; and a straightening member (40) provided in a connected row arrangement upstream of the cavity, the straightening member straightening the flow of a main smoke flow, which flows from upstream, to the cavity.

A cigarette filter inspection method of inspecting a solid flavor element to be disposed in a void between two filter plugs placed in outer filter wrapper, and the cigarette filter inspection method includes an illumination step of irradiating the void with illumination light, an imaging step of obtaining an inspection image of a region containing the void, a filler detection step of detecting the flavor element based on contrast between the void and the flavor element in the inspection image, and an inspection step of inspecting the flavor element detected in the inspection image.

There is provided a tobacco smoke filter (1) or filter element comprising: a rod (2) of a tobacco smoke filtering material; a continuous extruded element (7) extending longitudinally of the rod (2); and a flavouring agent.

A method for manufacturing a flavor capsule of tobacco according to an embodiment of the present disclosure may comprise: a membrane manufacturing step for manufacturing a membrane of a flavor capsule by a membrane manufacturing part that manufactures a membrane; a capsule manufacturing step for manufacturing the flavor capsule using an apparatus for manufacturing a capsule with the membrane manufactured during the membrane manufacturing step and a flavored liquid to be held in the membrane; and a hardening step for hardening the flavor capsule.

An aerosol-generating article (10) comprises: an aerosol-generating substrate (12); and a mouthpiece (14) in axial alignment with the aerosol-generating substrate (12), the mouthpiece comprising an additive segment (18) of filtration material comprising one or more breakable capsules (22), each breakable capsule (22) comprising an outer shell and an inner core containing an additive. The additive segment (18) of filtration material is spaced downstream from the aerosol-generating substrate (12) to define an upstream cavity (24) between the aerosol-generating substrate (12) and the additive segment (18) of filtration material, wherein the upstream cavity is substantially unfilled. A wrapper (26) circumscribes the additive segment (18) of filtration material and the upstream cavity (24).

The invention relates to a smoking article comprising a smoking article rod portion having a recess and a mouthpiece attachable to the smoking article rod portion. The mouthpiece includes an elongate cylindrical element arranged to be inserted into the recess by a user. The cylindrical element comprises an outer surface having at least one circumferentially extending raised area, and the at least one circumferentially extending raised area is configured to engage with an inner surface of the recess to prevent or restrict air flow between the inner surface of the recess and an outer surface of the mouthpiece.

A composition that includes vitamin A (e.g., retinol) and vitamin E (e.g., gamma-tocopherol), suitable for at least one of pulmonary administration, aerosolization, and intranasal administration. The composition can further include a pharmaceutically acceptable solid or liquid carrier. The composition can be in a unit dosage form or a metered dosage form and can be configured for pulmonary or intranasal administration. Also included are nutritional supplements, intranasal sprays, pulmonary sprays, pulmonary powders, cigarettes, and/or electronic cigarettes, each including the composition. Also included are methods of administering the composition to a human, e.g., within the oral cavity or within the respiratory system.

A smoking article includes an aerosol generating rod, and a filter portion disposed adjacent to the aerosol generating rod. The filter portion includes a filter body, a capsule member, and an adhesive. The capsule member contains a flavorant inside and is embedded in the filter body. The adhesive bonds the filter body and the capsule member.

An electronic smoking article includes a liquid aerosol formulation, a heater operable to at least partially volatilize the liquid aerosol formulation and form an aerosol and a tubular filter segment downstream of the heater. The tubular filter segment is operable to selectively filter aerosol particles and vapors from the aerosol.
