A non-combustible heating-type smoking article includes: a tobacco filler; and a wrapper enclosing the tobacco filler. The wrapper includes: a substrate sheet made of metal; a first sheet made of paper and bonded to one surface of the substrate sheet on a side of the tobacco filler; and a second sheet made of paper and bonded to one other surface of the substrate sheet on a side opposite to the one surface.

A component for an article for use in or as an aerosol provision system, the component including a tubular body of cellulose-based material sandwiched between inner and outer sheet materials, wherein the inner sheet material has a permeability of at least 200 CU. Also described is an article for use in or as an aerosol provision system, a method of manufacturing a component, and an apparatus configured for manufacturing a component.

A smoking article comprises a tobacco rod and a filter connected to the tobacco rod. The filter comprises a first filter segment and a hollow tube segment downstream of the first filter segment. The hollow tube segment defines a cavity at the mouth end of the filter providing an unrestricted flow channel that extends from the downstream end of the first filter segment to the mouth end of the filter. The length of the hollow tube segment is at least about 25 percent of the overall filter length. Further, the smoking article comprises a ventilation zone comprising at least one circumferential row of perforations provided at a location around the first filter segment.

The present invention discloses a disposable multi-stage cigarette holder filter apparatus, relates to the technical field of production of filter cigarette holders, and solves the problems of high cost, complex preparation process and poor filter effect of existing disposable filter cigarette holders. A composite filter rod, a filter layer, a cooling layer, a smoke dispersing layer, a cigarette holder connector and a cigarette body are sequentially connected from bottom to top into a cylinder structure; an outer packaging paper is arranged outside the cylinder structure; a plurality of air inlets are formed in a surface of the outer packaging paper corresponding to the smoke dispersing layer; and a filter capsule is arranged in the filter layer. The disposable multi-stage cigarette holder filter apparatus reduces the harm of tar and nicotine to smokers by introduction of air and multi-stage filtration, which uses mainly biomass materials wide in source as raw materials.

A cooling assembly for the aerosol-generating article according to an embodiment may include a cooling rod for cooling an aerosol generated by the aerosol-generating article; a perforation formed in the cooling rod and through which air passes; and an air volume regulator disposed on the outside of the cooling rod to cover the perforation, and regulating an amount of air passing through the perforation as the air volume regulator moves from one position to another.

A filter product for use in a consumer product. The consumer product may comprise a tobacco product, such as a combustible cigarette or a heat-not-burn stick. The filter product may comprise a plurality of cellulose acetate fibers having hollow core sections.

A cooling structure, which is located downstream of a smoking material portion provided in a smoking article and located upstream of a mouthpiece portion, includes: a body portion that has a tube shape having a hollow therein and is made of a paper material; and a plurality of perforations that are arranged in a circumferential direction of the body portion such that the inside and outside of the body portion are in fluid communication with each other.

An aerosol-generating article for producing an aerosol upon heating is provided, the article including: a rod of aerosol-forming substrate; and a filter positioned downstream of the rod, in which the rod and the filter are assembled within a wrapper, the article further including first and second air ingress zones located on the wrapper, the first and the second air ingress zones each being configured to allow an ingress of air into an interior of the article, the first air ingress zone including a substantially porous portion of the wrapper, the substantially porous portion having a porosity of at least 3000 Coresta Units, and a level of air ingress into the interior of the article through the first zone is greater than a level of air ingress into the interior of article through the second zone. An aerosol-generating system including the aerosol-generating article and an aerosol-generating device is also provided.

The present disclosure relates to an ultra-low nicotine smoking article. The smoking article includes a medium part and a filter part, in which the medium part includes a tobacco medium including flue-cured tobacco, dry ice expanded tobacco, and expanded stems, the tobacco medium includes 50% by weight (wt %) to 60 wt % of flue-cured tobacco, 20 wt % to 30 wt % of dry ice expanded tobacco, and 10 wt % to 30 wt % of expanded stems based on the total weight, and the tobacco medium has a nicotine content of 0.01% to 0.05%.
