Abstract
Description
Technical Field
[0001] This invention relates to a method for preparing a combustible heat source for smoking articles, a combustible heat source prepared by the method, and smoking articles comprising the same. Background Technology
[0002] Recently, heated tobacco products have become more popular than combustible tobacco products. Unlike existing tobacco products, non-combustible tobacco products involve inhaling the aerosol generated by the heated tobacco product medium, rather than the medium itself. Tobacco products that use a carbon heat source are one type of heated tobacco product.
[0003] Smoking products using the aforementioned carbon heat source generate aerosols by transferring heat from the carbon heat source to the smoking product medium downstream of the carbon heat source.
[0004] Smoking products that use combustible carbon heat sources, unlike typical heated electronic cigarettes which require specialized equipment, offer a smoking experience similar to traditional cigarettes. Therefore, it is expected to improve the convenience and satisfaction of consumers when smoking.

[0020] Invention Effects
[0021] Existing combustible heat sources are mainly composed of charcoal, which has the limitation of being difficult to ignite. Therefore, this invention, in order to more easily ignite a combustible heat source, utilizes a sugar-water solution, giving the heat source composed of the composition of this invention excellent flammability and combustibility compared to existing heat sources. Attached Figure Description
[0022] Figure 1 This is a graph showing the results of the combustion process when the heat source of the embodiment containing the sugar solution is burned.
[0023] Figure 2 This is a graph showing the results of the combustion process when a heat source is burned in a comparative example that includes solid sugar. Detailed Implementation
[0024] Currently, the demand for heated electronic cigarette products is constantly increasing. Most heated electronic cigarette products are devices with a [device + dedicated cigarette stick] structure. As a new type of smoking product, a product has been developed that installs a carbon-based heat source at the front end of the smoking product to provide a smoking experience similar to conventional smoking products. This invention aims to develop a combustible heat source that can provide a smoking experience (ignition, start-of-smoking time) similar to that of conventional smoking products.
[0025] To improve the ignitability of existing combustible heat sources, this invention uses an ignition accelerator composed of potassium nitrate and sugar. When mixing materials within a combustible charcoal heat source, a small amount of powdered potassium nitrate / sugar is used compared to the main charcoal powder; however, uneven mixing can cause problems during combustion. To prevent this, this invention adds a small amount of oil / water to the charcoal heat source and adds sugar in the form of a sugar solution to achieve uniform distribution within the combustion chamber. This method has been proven to resolve the problems encountered during combustion, thus completing this invention.
[0026] Therefore, the present invention discloses a method for preparing a combustible heat source, a combustible heat source prepared therefrom, and a smoking product including the same, which achieves excellent ignitability and sustained combustion by adding sugar, and makes the sugar uniformly distributed, thereby achieving stable combustion without phenomena such as sparks flying.
[0027] Therefore, the present invention provides a method for preparing a combustible heat source for smoking products, comprising: step S1, mixing toner with an organic binder; step S2, after step S1, adding a sugar solution to prepare a combustible heat source composition for smoking products; step S3, adding oil to the composition; and step S4, compressing the composition.
[0028] Furthermore, the present invention provides a combustible heat source for smoking products prepared by the above method.
[0029] Furthermore, the present invention provides a smoking article including the aforementioned combustible heat source.
[0030] The present invention will now be described in detail.
[0031] The combustible heat source composition of the present invention comprises carbon powder and an organic binder, characterized in that a sugar aqueous solution is further added to the composition. In the preparation of conventional heat sources, carbon powder is required, and the remaining materials are usually in solid form. However, the present invention achieves stable combustion by using a sugar aqueous solution to uniformly disperse the sugar in the heat source.
[0032] Preferably, the sugar solution content in the composition is 5% to 15% by weight, more preferably 5% to 10% by weight, so as to ignite within 30 seconds and continue to burn for about 3 minutes.
[0033] The sugar solution is prepared by mixing sugar and water in a weight ratio of 7:3 to 5:5. Preferably, the sugar content is greater than or equal to the water content. More preferably, it can be prepared by mixing in a weight ratio of 6:4 to achieve uniform dispersion.
[0034] The sugar is a sugar alcohol, which may be sorbitol, xylitol, mannitol, maltitol, lactitol, erythritol, reduced paraffinose, or reduced starch syrup. Preferably, mannitol has low hygroscopicity and is suitable for use as a heat source.
[0035] Potassium nitrate can be added to the sugar to act as an ignition accelerator. The content of potassium nitrate can be from 5% to 15% by weight.
[0036] The charcoal serves as the primary heat source, acting as fuel to ignite and sustain combustion. The charcoal content is preferably 40% by weight or more relative to 100% solids, and when the content is 40% by weight or more, the required temperature for sustained smoking for more than 3 minutes can be maintained.
[0037] When preparing a heat source, a polyol can be added as an oil component to the composition of the present invention. By adding the polyol, a combustible gas can be generated after the heat source is ignited, thereby improving ignitability and combustion duration. The polyol can support combustion and can be glycerol or propylene glycol. The content of the polyol relative to 100 parts by weight of solid components can be 1 to 5 parts by weight. Within the above range, ignitability and combustion duration are excellent, and 1 to 3 parts by weight are more preferably used to rapidly ignite and maintain stable combustion.
[0038] The heat source can be ignited within 30 seconds and continue to burn for more than 140 seconds. The diameter of the heat source with the above ignition and burning time can be 5 mm to 10 mm, and the length can be 8 nm to 15 nm, but is not limited to these.
[0039] According to one embodiment of the invention, the heat source can be combined with at least one adhesive. Preferably, the at least one adhesive can be an organic adhesive. Known suitable organic adhesives may include, but are not limited to, carboxymethyl cellulose (CMC), guar gum, methyl cellulose (MC), hydroxypropyl methyl cellulose (HPMC), and combinations thereof.
[0040] Furthermore, the combustible heat source used in the smoking article of the present invention may include at least one additive to improve the properties of the combustible heat source. Suitable additives include, but are not limited to, additives that promote the consolidation of the combustible heat source (e.g., sintering aids), additives that promote the ignition of the combustible heat source (e.g., oxidants such as perchlorates, chlorates, nitrates, peroxides, potassium permanganate, zirconium, and combinations thereof), additives that promote the combustion of the combustible heat source (e.g., potassium and potassium salts such as potassium citrate), and additives that promote the decomposition of at least one gas generated by the combustion of the combustible heat source (e.g., catalysts such as CuO, Fe2O3, and Al2O3).
[0041] Furthermore, a flammable heat source may also include an ignition aid. As used herein, the term "ignition aid" refers to a substance that releases one or more of energy and oxygen during the ignition of a flammable heat source, wherein the release rate of the energy and oxygen released by the substance is not limited by the diffusion of surrounding oxygen. That is, during the ignition of a flammable heat source, the release rate of the energy and oxygen released by the substance is independent of the rate at which surrounding oxygen reaches the substance. As used herein, the term "ignition aid" is also used to refer to an elemental metal that releases energy during the ignition of a flammable heat source, wherein the elemental metal has an ignition point below about 500°C and a heat of combustion of at least about 5 kJ / g. The combustion improver may be an alkali metal salt (alkali metal citrate salt, alkali metal acetate salt, and alkali metal succinate salt, etc.), alkali metal halide salt (alkali metal chloride salt, etc.), alkali metal carbonate salt, or alkali metal phosphate salt, which are considered to modify carbon combustion.
[0042] Examples of suitable oxidizing agents include, but are not limited to, nitrates such as potassium nitrate, calcium nitrate, strontium nitrate, sodium nitrate, barium nitrate, lithium nitrate, aluminum nitrate, and ferric nitrate; nitrites; other organic and inorganic nitro compounds; chlorates such as sodium chlorate and potassium chlorate; perchlorates such as sodium perchlorate; chlorites; bromates such as sodium bromate and potassium bromate; perbromates; bromates such as sodium borate and potassium borate; ferrates such as barium ferrate; ferrites; manganates such as potassium manganate; potassium permanganate; benzoyl peroxide and per... Organic peroxides such as acetone oxide; inorganic peroxides such as hydrogen peroxide, strontium peroxide, magnesium peroxide, calcium peroxide, barium peroxide, zinc peroxide, and lithium peroxide; superoxides such as potassium superoxide and sodium acetate; iodates; periodate; iodite; sulfates; sulfites; other sulfoxides; phosphates; superphosphates; phosphites; and phosphanite.
[0043] While this improves the ignition and combustion performance of the combustible heat source, the inclusion of combustion improvers and combustion additives can simultaneously produce undesirable decomposition and reaction products during the use of the smoking article. For example, nitrates included in the combustible heat source to improve combustion can produce nitrogen oxides upon decomposition. By including a combustible heat source in the smoking article of the present invention, it is advantageous to substantially prevent or suppress the decomposition and reaction products that may enter through the air inhaled by the smoking article of the present invention during use.
[0044] The combustible carbonaceous heat source used in the smoking article of the present invention is prepared by the above method using prior art known to those skilled in the art.
[0045] Preferably, at least one carbon-containing material can be mixed with at least one binder and any other additives (if present), and the mixture can be pre-formed into the desired shape to produce a combustible carbonaceous heat source for the smoking article of the present invention. The mixture of at least one carbon-containing material, at least one binder, and optional other additives can be pre-formed into the desired shape using any suitable and known ceramic forming method such as slip casting, extrusion molding, injection molding, and compression molding. In a preferred embodiment, the mixture can be pre-formed into the desired shape by stamping or extrusion, or a combination of both processes.
[0046] Preferably, a mixture of at least one carbon-containing material, at least one binder, and any other additives can be pre-formed into an elongate rod shape. However, it should be understood that at least one carbon-containing material, at least one binder, and any other additives can be formed into other desired shapes.
[0047] In one embodiment of the present invention, preferably, the combustible heat source may have a porosity between about 20% and about 80%, more preferably between about 20% and 60%. More preferably, when the combustible heat source is measured by mercury porosimetry or helium pycnometry, it may have a porosity of about 50% to about 70%. The desired porosity can be easily achieved when the above-described heat source preparation method is implemented using conventional methods and techniques.
[0048] Advantageously, the flammable heat source for the smoking article used in the present invention has a content of 0.6 g / cm³. 3 Approximately 1 g / cm 3 The apparent density between them.
[0049] Preferably, the combustible heat source has a mass between about 300 mg and about 500 mg, more preferably between about 400 mg and about 450 mg.
[0050] Preferably, the combustible heat source has a length between about 7 mm and about 17 mm, more preferably between about 7 mm and about 15 mm, and most preferably between about 7 mm and about 13 mm.
[0051] Preferably, the combustible heat source has a diameter between about 5 mm and about 9 mm, more preferably between about 7 mm and about 8 mm.
[0052] Preferably, the combustible heat source has a substantially uniform diameter. Alternatively, the combustible heat source can be made into a tapered shape such that the diameter at the rear of the combustible heat source is larger than its diameter at the front. In such an embodiment, the lateral cross-sectional area at the rear of the combustible heat source is at least about 60% of the lateral cross-sectional area of the smoking article.
[0053] Particularly preferred is that the flammable heat source is substantially cylindrical. For example, the flammable heat source may be a cylinder or cone with a substantially circular cross-section, or a cylinder or cone with a substantially elliptical cross-section.
[0054] Therefore, the combustible heat source can be used in smoking products that have a combustible heat source.
[0055] The term "smoking article" can refer to any inhalable product or product that provides a smoking experience, regardless of whether it is based on cigarettes, tobacco derivatives, expanded tobacco, reconstituted tobacco, or cigarette substitutes. For example, the term "smoking article" refers to inhalable products that can generate aerosols, such as cigarettes, cigars, and cigarillos.
[0056] The smoking article may include a combustible heat source, a medium, a thermally conductive packaging material, cigarette paper, a cooling section, and a filter rod, all composed of the aforementioned composition. The combustible heat source, medium, cooling section, and filter rod are arranged sequentially along the length direction; alternatively, the order of the other components can be freely changed, except that the combustible heat source is located upstream. Furthermore, other configurations may be included, or one or more of the aforementioned configurations may be omitted. The diameter of the smoking article may be 4 mm to 10 mm, and the circumference may be 14 mm to 29 mm. Alternatively, the length may be 45 mm to 100 mm.
[0057] The medium portion may include at least one of tobacco shreds, tobacco sheet shreds, tobacco leaves, expanded smoking articles, and nicotine extracts. The medium portion may contain nicotine. In addition to the medium portion, it may also include aerosol-generating substances. Aerosol-generating substances include esters of polyols such as polyols, glycerol monoacetate, glycerol diacetate, or glycerol triacetate, and aliphatic esters of monocarboxylic acids, dicarboxylic acids, or polycarboxylic acids such as dodecanedioate and tetradecanedioate. More specifically, for example, it may include at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. For example, the medium portion may include tobacco sheet shreds soaked in glycerol. However, the above are merely examples, and the present invention is not limited to the above examples.
[0058] The length of the medium portion can be between about 5 mm and about 20 mm, more preferably between about 8 mm and about 12 mm. The medium portion is wrapped in paper or other packaging material and can be formed in the shape of a stopper or a segment, containing a substance that releases volatile compounds upon heating. As described above, when the medium portion is formed as a stopper or segment, the entire stopper or segment, including any packaging material, can be considered as the medium portion.
[0059] The cooling section may include a cooling material. The cooling section includes a hollow tube with an open end, capable of cooling the airflow passing through the heat source and the medium section. The cooling section may be made of a polymeric material or a biodegradable polymeric material and may have a cooling function. For example, the cooling section may be paper, cardboard, plastic, such as cellulose acetate, ceramic, and combinations thereof. Further, the cooling section may include a corrugated sheet made of a material selected from the group consisting of metal foil, polymeric materials, and substantially non-porous paper or cardboard. In some embodiments, the aerosol cooling element may include a corrugated sheet made of a material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA), and aluminum. The length of the cooling section may be between 5 mm and about 30 mm, more preferably between about 8 mm and about 25 mm, and the length can be freely adjusted according to the heat temperature generated by the heatable heat source.
[0060] The filter rod portion includes filter material, and its shape is not limited. For example, the filter rod portion can be a cylindrical rod or a hollow tubular rod. Alternatively, it can be an embedded rod. If the filter rod portion is formed in multiple segments, at least one of the segments can be of other shapes. For example, the filter rod portion may include, but is not limited to, a fibrous, filamentous, or both of a filter rod bundle having at least one of a polymer, paper, cellulose acetate, activated carbon, and carbon. For example, the length of the filter rod portion can be 5 to 20 mm.
[0061] In addition, it may include a tipping paper that wraps the filter material and comes into contact with the mouthpiece. The tipping paper may have one or more perforations.
[0062] The filter rod portion can be made to produce a fragrance. For example, a fragrance liquid can be sprayed onto the filter material, or individual fibers coated with fragrance liquid can be inserted into the filter rod portion.
[0063] The cooling section and filter section may include an aerosol modifier. For example, one or more of the cooling section, filter section, and tipping paper of the smoking article of the present invention may contain at least one aerosol modifier. Suitable aerosol modifiers include, but are not limited to, flavoring agents and chemesthetic agents. The flavoring agent is any substance that adds one or more of the taste or aroma to the cigarette material and the aerosol generated by the aerosol-generating substances in the smoking article during use.
[0064] Furthermore, the cigarette paper is made of cellulose fibers obtained from wood, flax, or other materials, and can wrap the media portion, the entire smoking article including the media portion, or the portion other than the filter rod. The thickness of the base paper can be from about 30 μm to about 100 μm, and the basis weight of the base paper can be about 15 g / m³. 2 Approximately 80g / m 2 .
[0065] The downstream applications of the smoking article of the present invention may further include at least one aerosol modifier as a flavoring agent and a chemiluminescent agent. For example, at least one of the cooling section and the filter section of the smoking article of the present invention may include menthol or other flavoring agents that provide an icy sensation.
[0066] Furthermore, smoking articles including a flammable heat source may include a thermally conductive packaging material that encloses the flammable heat source and the medium portion. The thermally conductive packaging material may completely enclose the heat source and the medium portion, or it may enclose a portion of the heat source and a portion of the medium portion, or it may enclose a portion of the heat source and the entire medium portion. The thermally conductive packaging material transfers the heat generated by the flammable heat source to the smoking article material. The packaging material may be a metal foil packaging material such as aluminum foil, steel foil, iron foil, and copper foil; or a metal alloy foil packaging material. Any material that effectively transfers heat can be used without restriction.
[0067] A metal barrier can be formed between the heating heat source and the medium. Here, the metal barrier can prevent the flammable heat source from directly contacting the medium and can also prevent some components generated by the flammable heat source from moving into the medium.
[0068] The thickness of the barrier can be appropriately adjusted to achieve good smoke extraction performance. In some embodiments, the barrier thickness may be between about 10 micrometers and about 500 micrometers. The barrier may comprise one or more metallic materials that remain substantially thermally stable and non-combustible at the ignition and combustion temperatures of a flammable heat source. These materials are well known in the art and include, but are not limited to, aluminum, copper, stainless steel, and combinations thereof.

It should be understood that various modifications can be made to the embodiments, and the scope of this application is not limited to or restricted to the embodiments described below. All modifications to the embodiments, their equivalents, and even their substitutions are within the scope of this invention.

[0073] [Example]
[0074] 1. Preparation of a combustible heat source
[0075] A combustible heat source composition comprising charcoal, binder, potassium nitrate, and sugar was prepared according to the composition shown in Table 1 below. The heat source was formed into a cylinder with a diameter of 7 mm and a height of approximately 11 mm. The heat source materials were prepared according to the mixing ratio and then mixed using an atmospheric pressure mixer (THINKY ARE-310). During mixing, each material was added at 1500 RPM for 1 minute.
[0076] Add an appropriate amount of oil (PG) to the mixed powder as shown in Table 1 by weight and mix at 1500 RPM for 5 minutes. Divide the mixed sample into approximately 0.6 g portions and press them into cylinders using a press.
[0077] The pressurized sample was placed in a drying oven and dried at 80°C for 30 minutes.

[0087]
[0088] As can be seen from the results in Table 2, when the composition is as described in Examples 1 to 5, it exhibits good ignitability and combustibility. Figure 1 However, when the sugar ratio is 7:3 and 5:5, a slight boiling phenomenon occurs on the surface.

[0090] Furthermore, Comparative Example 2, which used a sugar solution with high water content, burned well, but the combustion started late and the surface burning time was too long.
[0091] Furthermore, in Comparative Example 3 using a 3% sugar solution, the combustion started late and the surface combustion lasted for a long time; in Comparative Example 4 using a 20% sugar solution, ignition was good, but sugar boiling and explosion occurred.
[0092] While the embodiments described above are based on limited examples and accompanying drawings, those skilled in the art can make various modifications and changes based on the foregoing description. For example, suitable results can also be obtained if the described techniques are performed in a different order than the described methods, and / or if the constituent elements in the described system, architecture, apparatus, or circuit are combined or integrated in different forms, or replaced or substituted by other constituent elements or equivalents.
