An article for use in a non-combustible aerosol provision system is described. The article includes an aerosol generating material and a mouthpiece connected to the aerosol generating material, the mouthpiece including a first body of material, and a second body of material downstream of the first body. The second body is offset from the first body so as to define a cavity between the first body and the second body. A breakable capsule is disposed in the cavity, and a diameter of the capsule can be less than the length of the cavity and the diameter of the cavity can be greater than the length of the cavity. A method of manufacturing an article is also described.

The invention provides a method of producing a tobacco smoke filter or filter element comprising: • heat treating a continuously advancing longitudinally extending strand of material; • cooling the heat treated continuously advancing strand; and • forming a longitudinally extending outer layer of tobacco smoke filtering material around the continuously advancing strand, to form a continuously advancing rod comprising a longitudinally extending strand (1a) of material and a longitudinally extending outer layer (2a) of tobacco smoke filtering material engaged around the longitudinally extending strand (1a). An apparatus for carrying out the method, and products of the method, are also provided.

Provided is a feature for a heated tobacco product having a tobacco rod formed by filling the inside of wrapping paper with a tobacco filler containing a tobacco raw material and an aerosol-source material, that prevents damage to an electric heater, such as bending or curving, during insertion into the tobacco rod, prevents the tobacco filler constituting the tobacco rod from being pressed toward the mouth end, and prevents the tobacco rod from deforming by buckling. This heated tobacco product has a tobacco rod formed by filling the inside of wrapping paper with a tobacco filler containing cut tobacco and an aerosol-source material, and is provided with a heater-insertion cavity that is open on the distal end surface side of the tobacco rod and extends in the axial direction of the tobacco rod, and into which a heater of a heating device is inserted.

Disclosed herein is a degradable cigarette filter comprising a cellulose ester and including a catalyst comprising a basic material, an enzymatic material, or combinations thereof. The catalyst, when exposed to water, may deacetylate the bloomed cellulose acetate tow by at least 10% in 20 days or less. The filters described herein therefore degrade more rapidly than other known cellulose acetate tow filters.

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.

A smoking article comprising a filter segment, the filter segment comprising a tow material and triacetin, wherein the filter segment further comprises an amino acid acetate salt and glycerine. The amino acid acetate salt and glycerine stabilize the triacetin in order to maintain the structural firmness of the tow material.
