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.

A filter element for use in a smoking article includes a filter material comprised of paper sheet having a crimped three-dimensional structure. Polyethylene glycol, triethyl citrate, or triacetin is interacted with the filter material to increase the selective removal of semi-volatile compounds from mainstream smoke being drawn through the filter element, over the filter material alone. An associated method of making a filter element for use in a smoking article is also provided.

The present disclosure relates to a filter for a smoking device, such as, but not limited to, a water pipe. The filter includes a body that is positionable over a mouthpiece of the smoking device, to filter impurities from smoke drawn therethrough, and a base that secures the body over the mouthpiece such that smoke is drawn therethrough, prior to inhalation by a user. The body can include one of more filtration layers, such as a first layer formed from a material selected to filter carcinogens and other impurities from the smoke prior to inhalation, and a second layer formed from a material selected to minimize or prevent the transmission of bacteria, viruses, or other contagions from a user's mouth to the smoking device. Each of the filtration layers can also be formed from one or more materials.

An insert system for use with a smokable (e.g., such as a pre-rolled or empty cone) including an internal partition for securing one or more flavor releasing mechanisms (e.g., flavored “click balls”) within a flavor mechanism holder and for use with a smokable item (e.g., a pre-roll cone, an empty cone, a pre-rolled or hand-rolled cigarette, etc.) is provided. The insert system is formed by rolling a section of suitable material to form an elongate member with an internal volume with a longitudinal partition. The longitudinal partition forms a compartment to receive and secure a flavor releasing mechanism held within a tubular holder. The insert system may then be coupled with a smokable to serve as the smokable's mouthpiece.

An article for use in a non-combustible aerosol provision system, the article comprising an aerosol generating material and a mouthpiece downstream of the aerosol generating material, wherein the mouthpiece comprises a body of material in the form of a cylinder having a longitudinal axis and a capsule embedded within the body of material such that the capsule is surrounded on all sides by the material forming the body, the capsule having a shell encapsulating a liquid aerosol modifying agent, and wherein the largest cross sectional area of the capsule measured perpendicularly to the longitudinal axis is less than 28% of the cross sectional area of the body of material measured perpendicularly to the longitudinal axis. There is also provided a system including the article and a non-combustible aerosol provision device for heating the aerosol generating material of the article.

A non-combustible aerosol provision system is described including an article (1) having an aerosol generating material (3) and a mouthpiece (2) downstream of the aerosol generating material, wherein the aerosol generating material provides an aerosol when heated and the mouthpiece comprises a capsule (11) and the part of the mouthpiece in which the capsule is located reaches a temperature of between 58 and 70 degrees Centigrade during use of the system to generate an aerosol. The burst strength of the capsule when located within the mouthpiece and prior to heating of the aerosol generating material can be between 1500 and 4000 grams force and the burst strength of the capsule within 30 seconds of use of the system to generate an aerosol can be between 1000 and 4000 grams force.

An article for use in a non-combustible aerosol provision system comprising an aerosol generating material comprising at least one aerosol forming material and a mouthpiece connected to the aerosol generating material, the mouthpiece comprising an upstream end adjacent to the aerosol generating material and a downstream end distal from the aerosol generating material, wherein the mouthpiece comprises a hollow tubular element formed from filamentary tow at the downstream end of the mouthpiece. There is also provided a system including the article and a non-combustible aerosol provision device for heating the aerosol generating material of the article, and a method of manufacturing articles for use in a non-combustible aerosol provision system.

Embodiments of the disclosure relate to an article for use in a non-combustible aerosol provision system, the article comprising an aerosol generating material and a mouthpiece connected to the aerosol generating material, wherein the mouthpiece comprises a cavity having an internal volume greater than 450 mm.sup.3. There is also provided a system including the article and a non-combustible aerosol provision device for heating the aerosol generating material of the article.

A device for use while burning smoking material and inhaling the resulting smoke is disclosed. The device can include a filter having a recess formed in a surface of a body along a curved face extending from the first end to the second end, the recess extending radially into the body. The smoking accessory can include a capsule containing a flavoring agent disposed within the recess. The device may be received by a first end a tubular member formed to receive a smoking material, that when burned passes smoke into the device.

A device for burning smoking material and inhaling the resulting smoke is disclosed. The device can include an truncated conical member formed from a material having an internal elongated cavity extending from an open end to a closed end. The elongated cavity can be configured to receive a smoking material. The smoking accessory can include a filter disposed within the truncated conical member and defining the closed end. The filter can have a recess formed in a surface of the body along a curved face extending from the first end to the second end, the recess extending radially into the body. The smoking accessory can include a capsule containing a flavoring agent disposed within the recess.
