Description

An Article for use in or as an Aerosol Provision System Technical field The present invention relates to an article for use in or as an aerosol provision system, to a non-combustible aerosol provision system and to a method of manufacturing an article. Background Certain tobacco industry products produce an aerosol during use, which is inhaled by a user. For example, tobacco heating devices heat an aerosol-generating substrate such as tobacco to form an aerosol by heating, but not burning, the substrate. Such tobacco industry products commonly include mouthpieces through which the aerosol passes to reach the user’s mouth. Summary In accordance with embodiments described herein, in a first aspect there is provided an article for use in or as an aerosol provision system, the article comprising: a rod of aerosol-generating material; and a disc adjacent to the rod of aerosol-generating material, wherein the disc is arranged to allow aerosol to pass through the disc. The disc can be downstream of the aerosol-generating material. The article can comprise a downstream section comprising the disc and a tubular element defining a cavity. The disc can be arranged immediately adjacent to both the rod of aerosol-generating material and the tubular element. The disc can be adhered to the tubular element. The downstream section can include a body of material comprising an aerosol modifying agent. The body of material can comprise an aerosol modifying agent in the form of a capsule. The disc can be formed of biodegradable material. The disc can be formed of fibrous material, optionally comprising fibres selected from at least one of cellulose, viscose, lyocell, rayon, viscose rayon, cupro and modal. The disc can be formed of paper or cardboard. The disc can comprise one or more apertures. Alternatively or in addition, the disc can be formed of a porous material. The disc can have a thickness which is less than half of its diameter. The disc can comprise a single aperture having a cross-sectional area of between about 0.2 and about 115 mm2, or between about 0.8 and about 65 mm2. The disc can comprise a plurality of apertures having a combined cross sectional area of between about 2 mm2 and about 115 mm2, or between about 5 mm2 and about 65 mm2. The disc can comprise a plurality of apertures having a combined cross-sectional area of between about 20 and about 150 mm2, or between about 50 and about 65 mm2. The one or more apertures can each be between about 0.5 mm and about 6 mm in diameter, or between about 2 mm and about 5 mm in diameter. The one or more apertures can each be between 2.5 mm and 4.5 mm in diameter. The one or more apertures can each be between 3 mm and 4 mm in diameter. The one or more apertures can have a cross-sectional shape which is circular, square or triangular. At least one of the one or more apertures can be covered and/or filled with an amorphous solid material. The amorphous solid material can comprise an aerosol- former material, a gelling agent and a filler. The amorphous solid material can have a thickness of about 0.015 mm to about 1.5 mm. The disc can have a thickness of between 50 and 500 micrometres, or between 100 and 300 micrometres, or between 150 and 250 micrometres. The rod of aerosol-generating material can comprise a plurality of strands or strips of aerosol-generating material. The strands or strips of aerosol-generating material can be arranged such that their longitudinal dimension is substantially parallel with the longitudinal axis of the article. The rod of aerosol-generating material can comprise at least one sheet of botanical material. The article can be for use in or as a non-combustible aerosol provision system. The rod of aerosol-generating material can comprise an aerosol former in an amount of from about 5% to about 40% of the aerosol-generating material on a dry weight basis. In accordance with embodiments described herein, in a second aspect there is provided a non-combustible aerosol provision system, comprising a non-combustible aerosol provision device, and an article according to the first aspect above. The non-combustible aerosol provision device can comprise a heating element configured for insertion into the rod of aerosol-generating material of the article. In accordance with embodiments described herein, in a third aspect there is provided a method of manufacturing an article according to the first aspect above, the method comprising: providing a source of aerosol-generating material and forming the aerosol- generating material into a rod; and arranging a disc adjacent to the rod of aerosol generating material.
