碳質熱源之空隙率可為50%以上。在此，所謂「碳質 * 熱源之空隙率」，係指在熱源之橫截面中經由以間隔壁分隔 而產生之熱源之每單位截面積的空間之比例。若空隙率未 達50% ，則有點火時之點火性不會大幅提高之傾向。空隙 率之上限係受限於將熱源組成物壓擠成形時之模具設計。 碳質熱源之空隙率以50%至78%為佳、以60至78%較佳。 〇 具備具有如此大的空隙率之碳質熱源之本發明之非燃燒型 抽煙物品之點火性提高。 碳質熱源之通路周長以70mm以上為佳。若通路周長未 達70丽，則有點火性會降低之傾向。通路周長之上限也受 限於模具之設計。在此，所謂「通路周長」係指例如在第 1圖所示之熱源之端面中呈格子狀之間隔壁10之面向空氣 通路之長度的合計。碳質熱源之通路周長以100至180mm ❹為佳。 碳質熱源之截面積以9mm2以上為佳。若截面積未達 9mm2，則在製品設計上為不佳。 ;ε炭質熱源之每單位截面積的通路周長以4顏/mm2以上 為佳。雖詳述於後，但得知每單位截面積的通路周長與點 火率可確認有一定的關係。得知若每單位截面積的通路周 長未達4顏/mm2，則使用一般點火法時點火性不良。 構成上述碳質熱源之熱源組成物以含有碳10至60重 量％為佳。若碳量未達10重量％，則熱源之燃燒性不足而 5 321394 201100029

invention belongs] • Product. ^ :, a non-combustible smog with a carbonaceous heat source [Prior Art] # ^ , Ν ^ ^ ^ 弋 Cigarettes. The non-combustible smoking article is provided with a heat source portion of the member and a flavor generating portion including a flavor generating material obtained by storing the camphor component in a suitable substrate. The heat source unit generally uses a carbonaceous heat source. ♦ In the carbonaceous heat source used so far, a plurality of holes are provided in the axial direction, and the through holes are used to heat the gas-generating portion, and the function of the gas passage is to cause the initial combustion characteristics to be exerted. The invention is set forth in the specification of U.S. Patent No. 4,881,556, U.S. Patent No. 4,967,774, U.S. Patent No. 4,989,619, U.S. Patent No. 4,991,606, and U.S. Patent No. 5,067,499. Further, there is an example in which the heat source portion is formed into a special structure (U.S. Patent No. 5,518,062). Most of these non-combustible smoking articles use carbonaceous heat sources that are wrapped in rolls or insulation. Further, the conventional carbonaceous heat source preferably contains more than 60% by weight (preferably more than 80% by weight) of carbon. SUMMARY OF THE INVENTION A conventional carbonaceous heat source has indeed been improved from the viewpoint of efficiently conducting heat to an aerosol generating portion. However, the heating source composed of the extruded product of the heat source composition is more difficult to ignite than a general cigarette except that a plurality of air passages are provided. In addition, due to the large amount of carbon used, the carbon f heat source will shrink during combustion and there will be a detachment from the smoking article and the 'in order to efficiently transfer heat to the gas-dissolving generating portion and prevent falling off' The heat source and the like are coated with a heat source portion. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a non-combustible smoking article which has an improved ignitability and which is less likely to fall off when it is smoked, and which does not require a carbonaceous heat source such as a heat insulating material. According to the present invention, a non-combustion type smoking article can be provided, which is provided with a carbonaceous heat source and a gas-generating generating portion, wherein the carbon-derived source is in the form of a cylinder and is disposed in the (four) and the cross-section is in a lattice shape. a wall having an air passage defined by the aforementioned partition walls. [Embodiment] Hereinafter, the present invention will be described in detail. The non-combustion type smoking article of the present invention has a carbonaceous heat source and an aerosol stemming unit. The carbonaceous heat source has a cylindrical outer wall and is disposed inside the i and has a cross-sectional shape in a lattice shape, and has the aforementioned The wall is divided into air and politics. The above-mentioned lattice may be in any form, and may be, for example, a square lattice, a corner lattice, a three-corner lattice m 丨 indicating an end surface of a carbonaceous heat source having a partition wall formed into a square σ, and 2 representing an angular lattice lattice. The end face of the partition wall-heat source, 3 indicates the end face of the carbon source of the wall of the angled scorpion, 4 indicates that it has the opening; the end face of the carbon f heat source between the radial grids (4) . Further, the rabbit heat source of Fig. 5 is disposed in the partition wall of the carbonaceous heat source, and the cross section thereof is 321394 4 201100029. The cross section does not need to be formed in a uniform lattice, and may be formed by including a lattice which is not uniform. The carbonaceous heat source may have a void ratio of 50% or more. Here, the "void ratio of the carbonaceous material* heat source" means the ratio of the space per unit sectional area of the heat source generated by the partition walls in the cross section of the heat source. If the void ratio is less than 50%, the ignitability at the time of ignition does not tend to be greatly improved. The upper limit of the void ratio is limited by the mold design when the heat source composition is extrusion molded. The carbonaceous heat source preferably has a void ratio of 50% to 78% and preferably 60 to 78%.点火 The non-combustible smoking article of the present invention having a carbonaceous heat source having such a large void ratio has improved ignitability. The circumference of the carbonaceous heat source is preferably 70 mm or more. If the circumference of the passage is less than 70 liters, the ignitability tends to decrease. The upper limit of the perimeter of the passage is also limited to the design of the mold. Here, the term "passage circumference" refers to, for example, the total length of the partition wall 10 having a lattice shape in the end surface of the heat source shown in Fig. 1 facing the air passage. The perimeter of the carbonaceous heat source is preferably from 100 to 180 mm. The cross-sectional area of the carbonaceous heat source is preferably 9 mm 2 or more. If the cross-sectional area is less than 9 mm2, the product design is not good. The circumference of the passage per unit cross-sectional area of the ε carbonaceous heat source is preferably 4 mm/mm 2 or more. Although it is described in detail later, it is known that the perimeter of the passage per unit cross-sectional area has a certain relationship with the ignition rate. It is found that if the circumference of the passage per unit sectional area is less than 4 mm/mm2, the ignitability is poor when the general ignition method is used. The heat source composition constituting the above-described carbonaceous heat source preferably contains 10 to 60% by weight of carbon. If the amount of carbon is less than 10% by weight, the flammability of the heat source is insufficient and 5 321394 201100029 is not good. If 60% by weight of carbon is contained, ignitability and flammability are sufficient. The source of the carbon to be used is not particularly limited, and known carbon can be used. The heat source composition constituting the carbonaceous heat source used in the non-combustion type smoking article of the present invention has a sufficient ignition rate even if it is a lower carbon amount than the above. Further, the heat source composition may contain calcium carbonate (particles) and other inorganic additives for lowering the maximum temperature of the carbonaceous heat source and reducing the amount of carbon monoxide generated. The inorganic additive may generally be up to 98% by weight relative to 1% by weight of carbon. Proportionally formulated, and preferably formulated in a ratio of up to 8% by weight, more preferably from 0.100 to 3.75% by weight. In order to make calcium carbonate and carbon are bonded, a binder is contained. % _ _ For the binder, alginate, carboxymethylcellulose or a salt thereof, pectin or a salt thereof, carrageenan or a salt thereof, etc. may be used. In order to easily generate an aerosol at the beginning of smoking, the heat source composition may contain An aerosol generating substance such as poly(tetra), etc. The aerosol generating substance which may be contained in the heat f composition may be formulated in a proportion of up to 98% by weight, and preferably at a maximum of 3. G by weight, relative to carbon % by weight. %Ratio The blending, more preferably in a proportion of 1.5% by weight, and the heat source composition may also contain paper poly, tobacco fine powder, etc. Relative to the stone counter% by weight, paper medicine, tobacco stem 4 > human water The total amount of 堙 细 细 细 一般 一般 一般 一般 一般 一般 一般 一般 一般 一般 一般 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 1394 In the carbonaceous heat source, % of the raw materials before forming the carbonaceous heat source may be mixed, such as boron, sulphur, dream, titanium, iron, diamond, nickel, zinc, wrong, wrong, sharp, key, sputum, money, silver, Tin, garnish, give, group, tungsten, chain, iron, silver, Ming, gold, oxides of these, or mixtures of these, etc. Reduce the carbon monoxide catalyst. For the same carbonaceous heat source, also the axis of the air passage One or all of the directional surface is coated with the desired material. In particular, the carbonaceous heat source may be rendered substantially non-breathable via the layer of coated particles. The coated material preferably has low thermal conductivity, thermal stability, and even The temperature at which the carbonaceous heat source is burned is also non-flammable. Preferred coatings For example, clay or metal oxides, such as: iron oxide, oxidized sulphur, titanium oxide, oxidized slag, oxidized dream oxidized I, oxidized oxidized, oxidized bromine, zeolite, canned acid, other ceramic materials and these The coating material preferably contains clay or iron oxide. Further, the coating materials may also contain a catalyst having an oxidation reaction function for promoting oxidation from carbon monoxide to carbon dioxide. For example, the catalyst may be turned over. Other materials such as those described in the specification of U.S. Patent No. 5,040,551 may be used in order to apply a desired amount of material to one or both of the axial direction surfaces of the air passage. For example, The solution or suspension of the coating material is sprayed, wetted, and painted. Alternatively, a gasket (1 i ner) composed of a coating material is inserted into part or all of the axial direction surface of the air passage. For example, a substantially non-breathable hollow tube can be inserted into the axial direction of each air passage. The carbonaceous heat source used in the non-combustible smoking article of the present invention is 7 321394 201100029 which is burned in the form of a partition wall having a lattice shape in cross section. The reason for this is that it is more conventional than the above to further reduce the amount of carbon of the heat source composition. Therefore, even if the heat source is not covered by a heat insulating material or the like as described below, it is possible to prevent the heat source from falling off from the smoking article during smoking. The carbonaceous heat source described above can be formed by a forming means such as extrusion molding using a mold corresponding to the intended lattice. The carbonaceous heat source used in the present invention does not need to be provided with a heat insulating material or a roll paper as in a general non-combustible smoking article, and can be sufficiently burned in an exposed state and is not easily peeled off. In this way, the steps of providing a heat insulating material around the carbonaceous heat source can be omitted, which is advantageous in terms of cost. In the non-combustion type smoking article of the present invention, the aerosol generating portion can be provided, for example, in a form physically separated from the carbonaceous heat source. As the aerosol-generating substance contained in the aerosol generating portion, for example, a polyhydric alcohol such as glycerin, propylene glycol, triethylene glycol or tetraethylene glycol; decyl stearate, dinonyl dodecanoate, and fourteen A carboxylic acid aliphatic ester such as dimethyl alkanoate. Aerosol generating materials are typically carried on a suitable carrier. As the carrier, a porous material such as paper or activated carbon can be used. The aerosol generating material is adjusted by absorbing or adsorbing the aerosol generating material to the porous material. Alternatively, a polydextrose gel such as a Kadland polysaccharide described in the specification of Japanese Patent No. 3118462 can be used as a carrier. In other words, an aerosol generating material is added to the aqueous dispersion of the thermally irreversible coagulated polydextrose, and cast into a film sheet shape on, for example, a stainless steel belt, and then dried by heating to gel the polydextrose. A polydextrose gel carrying an aerosol generating substance can be cut or pulverized and used as an aerosol generating material. An aerosol produced by supporting an aerosol generating material on a carrier can be used to form a circle formed of a non-combustible material such as a paper sheet containing a glass fiber sheet, a ceramic, or a metal foil. Inside the barrel, an aerosol 'generating portion is formed. In order to impart a fragrance to an aerosol generated from an aerosol generating portion, the smoking article of the present invention may be provided with a flavor generating portion containing a flavor generating material at a rear end of the aerosol generating portion. As the flavor-generating material, tobacco yarn or the flavor-generating medium described in the specification of Japanese Patent No. 3118462 can be used. The flavor generating material is stored in the same cylinder as the cylindrical body of the aerosol generating portion. 〇 Also, the smoking article of the present invention may have a filter used in a general cigarette at the last end. Hereinafter, an example of a non-combustion type smoking article using a heat source composed of a carbonaceous heat source composition of the present invention will be described with reference to Fig. 2 . The smoking article 100 shown in Fig. 2 includes an aerosol generating unit 11, a carbonaceous heat source 12 provided at the tip end of the aerosol generating unit 11, a flavor generating unit 36 provided at the rear end of the aerosol generating unit 11, and The fragrance creates a filter portion 14 at the rear end of the crotch portion 36. The aerosol generating portion 11 has a cylindrical body 111 formed of a non-combustible material, and a particulate-like aerosol generating material 112 composed of a carrier carrying the aerosol generating material is stored in the cylindrical member 111. The carbonaceous heat source 12 is circular in shape and may be in various lattice shapes as described above. Next, the flavor generating portion 36 has a cylindrical member 361 formed of a non-combustible material, and the flavor generating material 362 is stored in the cylindrical member 361. The filter unit 14 is composed of a filter member 141 (e.g., 9 321394 201100029 such as cellulose acetate vinegar fiber bundle) used in general cigarettes, and its outer periphery is wrapped by a take-up paper 142. The gas-soluble enthalpy generating unit 11 and the aroma generating unit 36 and the damper unit 14 are generated by aerosol coating by the outer surface of the scent generating unit 36 and the filter unit 14 such as a sheet of paper 2G of cigarette paper. After the portion u is connected to the periphery of the end. In addition, 'in the cigarette article UK', 'to dilute the mainstream smoke component (e.g., - carbon oxide)' may have an opening to allow air to flow when smoking. In the smoking article 1 shown in Fig. 2, an opening 〇p is formed in the filter unit 14 so as to penetrate the paper sheet 20 and the take-up paper 142. Such a non-combustible smoking article may be exemplified by a general cigarette, and will be described in more detail with reference to examples, but the present invention is not limited thereto.

Then, the heat source and the heat insulating material covering the heat source are taken out from the above AIRS product, and inserted in accordance with the above. Carbonaceous heat sources for samples 1 through 6. In other words, the composition of the smoking article other than the heat source is the same as that of the AIRS product. (Conventional Example 1) Conventional Example 1 is a non-combustible smoking article manufactured by the above-mentioned Japanese tobacco industry co., Ltd. under the trade name AIRS. The ignitability test was carried out as follows. After preheating for 3 seconds using an electric igniter, smoking was performed at 35 mL/2 seconds. Then, after 58 seconds, the cigarette was smoked again (that is, the 60-second smoking cycle). At this time, it was confirmed by the naked eye whether the whole heat source was red-hot, and the person who was red-hot was judged as "ignitable", and those who did not show red heat were judged as 11 321394 201100029. :fire". For samples 1 to 6 and the conventional example 1, the test was carried out by using 〇 〇 as ' to test the number of the ignitable ", and the ignition rate = A + 1 〇 x (10) (%)" rate. The unit cross-section of the heat source of the product represents the ignition rate of 檨:. The result is shown in Fig. 3. Circular Marks The igniting rate of the anaerobic heat source of the stone of the Η丨^ ’^ triangle symbol table: the ignition rate of the anti-quality heat source to the stone. In this condition, the difference in ignition ratio between the following two and the conventional example 1 was not observed, but the ignition rate of the sample 3 was about _. In other words, the design of each parameter of an important heat source has been known in order to improve ignitability. In addition, the ignitability is improved by using the mass heat source: ==: the air passage (four) which is separated by the wall of the crucible. The influence of the road perimeter), in order to confirm the number of grids (the circumference of the passage is measured) (4) _ cross-sectional area is maintained constant, change the production of the second 6 to the same: (4) heat source composition, using various molds, and the void ratio becomes constant In the way, change the original grid to change the source wall and change the perimeter of the passage.

In other words, the composition of the smoking article other than the heat source is the same as that of the AIRS product. In this fiscal, the ignition is based on the use of electric ignition (four) first heating for 2 seconds ^ t 35 hearts for 2 seconds to gamble. Since the carbon source of the real _ 2 is 2 fire' and the embodiment! The difference in the ignition rate obtained under the condition is not allowed to be present, so the preheating time is shortened from 3 seconds to 2 seconds, so that the difference in dots appears. The 4th towel indicates the relationship between the channel perimeter and the rate per unit cross-sectional area of the Carbonaceous Thermal Society. Here, 'the case where the preheating time is used for 2 seconds and J, respectively. By the first? The figure shows that the ignition rate of 'preheating for 3 seconds is 乂' phase*〒. Further, the shortening of the preheating time to 2 is the same as that of the samples 1-6 to 6, and it is confirmed that the igniting rate is increased by the increase in the "peripheral length of the passage per unit heat source cross-sectional area 321394 13 201100029". At the same time, it can be confirmed that under the condition that the heat source wearing area and the gap (four) are determined, the thickness of the partition wall is made extremely thin and the interval between the grids is narrowed, thereby increasing the number of grids and increasing the circumference of the passage. Improve ignitability. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 (a) to (e) are end views of a carbonaceous heat source used in the non-combustion type smoking article of the present invention.
