Definitions
- the present invention relates to a smoking article comprising a combustible heat source having airflow holes formed therein.
- a number of smoking articles have been proposed in which the smoking article is heated rather than combusted. Unlike conventional cigarettes, these non-combustion smoking articles are used by sucking an aerosol generated by heating the smoking article medium without burning the smoking article medium. As one of the types of such heated smoking articles, there is a smoking article to which a combustible carbon heat source is applied.
- a smoking article to which the combustible carbon heat source is applied generates an aerosol by heat transfer from the combustible carbon heat source to a smoking article medium located downstream of the combustible carbon heat source.
- Smoking articles products to which a combustible carbon heat source is applied have a smoking form similar to traditional cigarette products, unlike general heated electronic smoking articles using a dedicated device, and the demand is increasing.
- Patent Document 1 WO2009/022232 (2009.02.19)
- An object of the present invention is to provide a smoking article including a combustible heat source in which an airflow hole is formed in the combustible heat source and the combustion durability is improved.
- the present invention relates to a smoking article 100 comprising a combustible heat source
- a first portion (110) comprising a combustible heat source
- a second portion (120) comprising tobacco material
- a buffer space 220 located between the first part 110 and the second part 120 and connected to the air flow hole 210,
- a smoking article comprising a combustible heat source is provided wherein the air flow hole does not penetrate the combustible heat source.
- the diameter of the air flow hole (d 2 ) has a length of 5 to 60% of the combustible heat source diameter (d 1 ), and the depth of the air flow hole (l 2 ) is the combustible heat source length (l 1 ) It may have a length of 10 to 80% of.
- the combustible heat source may have a diameter (d 1 ) of 6 to 12 mm, and the air flow hole (d 2 ) may have a diameter of 1 to 5 mm.
- the length of the combustible heat source (l 1 ) is 10 to 16 mm
- the depth (l 2 ) of the air flow hole may be 1 to 12 mm.
- the buffer space 220 may have a length of 0.5 to 3 mm.
- a metal barrier 300 may be formed at an end of the second portion 120 that contacts the buffer space 220 .
- a thermally conductive wrapper 160 surrounding the first part 110 and the second part 120 may be included.
- the thermally conductive wrapper 160 may include one or more perforations 161 on an outer circumferential surface.
- the smoking article may comprise an outer cigarette paper 150 surrounding the smoking article comprising a combustible heat source.
- one or more perforations 161 and 151 may be provided on outer circumferential surfaces of the thermally conductive wrapper 160 and the outer cigarette paper 150.
- the size of the perforation may be 0.5 mm or less.
- the smoking article (100) comprising a combustible heat source further comprises a third portion (130) comprising a cooling material and a fourth portion (140) comprising a filter material. It could be
- a smoking article comprising a combustible heat source of the present invention is characterized by excellent combustion sustainability by using a combustible heat source having an air flow hole.
- FIG. 1 is a diagram showing the construction of a smoking article comprising a combustible heat source of the present invention.
- Figure 2a is a schematic diagram showing the delivery path of the heated air flow during smoking of the smoking article of the present invention.
- Figure 2b is a view showing a path through which external air is introduced during smoking of the smoking article of the present invention.
- FIG 3 is an enlarged view of the combustible heat source of the present invention.
- lengthwise direction of a smoking article comprising a combustible heat source means the direction in which the length of the smoking article comprising a combustible heat source extends or the direction in which combustion proceeds when the smoking article comprising a combustible heat source is combusted.
- upstream and downstream refer to the part where air enters from the outside of the smoking article including the combustible heat source when the user sucks in outside air using the smoking article including the combustible heat source.
- upstream and the portion where air exits from the inside to the outside of the smoking article containing the combustible heat source is "downstream”.
- upstream and downstream may be used to indicate the relative position or orientation between parts or segments comprising a smoking article that includes a combustible heat source.
- the upstream end of the heat source may refer to the end face of the smoking article on the heat source side
- downstream end of the heat source may refer to the face facing the buffer space.
- FIG. 1 is a diagram showing the configuration of a smoking article including a combustible heat source.
- a smoking article 100 comprising a combustible heat source includes, for example, a first portion 110 comprising a combustible heat source and a second portion 120 comprising tobacco material, wherein the The first portion 110 and the second portion 120 are arranged in order relative to the longitudinal direction of the smoking article 100 including the combustible heat source.
- the smoking article 100 is characterized by having an airflow hole 210.
