Description

Aerosol-forming rod manufacturing method and apparatus {Method and apparatus for making a rod of aerosol-forming substrate}

Embodiments relate to a method and apparatus for making an aerosol-forming rod.

In recent years, there has been an increasing demand for alternative methods that overcome the disadvantages of conventional cigarettes. For example, there is an increasing demand for a method of generating an aerosol as the aerosol-generating material in the cigarette is heated rather than a method of burning a cigarette to produce an aerosol. Accordingly, research into a heated cigarette or a heated aerosol generating device is being actively conducted.

In the prior art, a rod is manufactured in the form of a plate leaf sheet, and in order to maintain the hardness required for stick manufacturing, a large weight, for example, a plate leaf weight of 3,000 mg based on a circumference of 22 mm and a length of 120 mm is required. In addition, since the rod is formed in a sheet state, there is a problem in that recycling is difficult when off-spec occurs.

The terms used in the embodiments are selected as currently widely used general terms as possible while considering the functions in the present invention, but may vary depending on the intention or precedent of a person skilled in the art, the emergence of new technology, and the like. In addition, in a specific case, there is a term arbitrarily selected by the applicant, and in this case, the meaning will be described in detail in the description of the corresponding invention. Therefore, the term used in the present invention should be defined based on the meaning of the term and the overall content of the present invention, rather than the name of a simple term.

In the entire specification, when a part “includes” a certain element, it means that other elements may be further included, rather than excluding other elements, unless otherwise stated.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those of ordinary skill in the art can easily carry out the embodiments of the present invention. However, the present invention may be implemented in several different forms and is not limited to the embodiments described herein.

As used herein, the term 'rod' is generally used to refer to a cylindrical member of substantially circular, oval or elliptical cross-section. This technique includes not only 'sheet' but also rod formation using 'cut filler'.

As used herein, the term 'aerosol-forming material' refers to a material capable of releasing a volatile compound upon heating to generate an aerosol. Tobacco can be classified as a homogeneous tobacco sheet or cut filler consisting of an aerosol-forming material, in particular an aerosol former. The aerosol-forming substrate may consist of or consist of an aerosol-forming material.

The term 'homogeneous tobacco material' as used herein refers to a material formed by agglomerating particulate tobacco.

As used herein, the term 'collected' means that sheets of tobacco material are convoluted, folded, on the other hand compressed or constricted substantially transverse to the cylindrical axis of the rod. or dense cut filler rod formation.

The heated aerosol-generating system operates by heating the aerosol-forming substrate to generate an aerosol from the material of the substrate. Aerosols may be inhaled by consumers. Upon heating of a substrate comprising rods formed as described herein, tobacco flavor is released from the sheet or cut filler of tobacco material.

As described herein, there is provided an aerosol-generating article comprising the rods described herein.

Many aerosol-generating articles have previously been proposed in which the aerosol-forming substrate is heated rather than combusted. In heated aerosol-generating articles, typically, the aerosol is generated by heat transfer from a heat source, eg, a chemical, electrical, or combustible heat source, to a physically separate aerosol-generating article, which is located within, around or downstream of that heat source. can do.

As used herein, the term 'aerosol-generating substrate' refers to a substrate formed of, or consisting of, an aerosol-forming material capable of releasing a volatile compound upon heating to generate an aerosol.

The rods described herein are particularly adapted for use as an aerosol-generating substrate of a heated aerosol-generating article. The aerosol-generating substrate of a heated aerosol-generating article generally has a significantly shorter rod length than a rod of combustible smokable material of conventional light-ended smoking articles.

In one embodiment, the rods described herein can be used as an aerosol-generating substrate of a heated aerosol-generating article comprising a combustible heat source and an aerosol-generating substrate downstream of the combustible heat source.

The rods described herein may be used as an aerosol-generating substrate in a heated aerosol-generating article for use in an electrically actuated aerosol-generating system in which the aerosol-generating substrate of the heated aerosol-generating article is heated by an electrical heat source.

A system can be provided that includes an electrically actuated aerosol-generating device and an aerosol-generating article for use in the device. The aerosol-generating article may consist of a rod or an aerosol-forming substrate as described herein.

A preferred embodiment consists of a sheet or cut filler of homogeneous tobacco material. A homogeneous sheet of tobacco material or cut filler may be formed by agglomerating particulate tobacco obtained by grinding or grinding one or both of tobacco leaf lamina and tobacco leaf stems. Alternatively or additionally, a sheet or cut filler of homogeneous tobacco material tobacco may consist of one or more tobacco dusts, tobacco fines and other particulate tobacco by-products formed, for example, during the processing, handling and shipping of tobacco. When the rod according to the invention is intended for use as an aerosol-forming substrate in a heated aerosol-generating article, the homogeneous tobacco material used to form the rod is preferably fine particles obtained by grinding or otherwise comminuting tobacco leaf lamina. made of cigarettes

In certain embodiments, the homogeneous sheet of tobacco material may have a tobacco content per dry weight of at least about 40 weight percent, or at least about 50 weight percent per dry weight. In another embodiment, the sheet of homogeneous tobacco material has a tobacco content of at least about 70 weight percent on a dry weight basis. When the rod according to the invention is intended for use as an aerosol-forming substrate in a heated aerosol-generating article, the use of a homogeneous tobacco material with a high tobacco content advantageously generates an aerosol with enhanced tobacco flavor.

The homogeneous tobacco material may consist of one or more endogenous binders that are tobacco endogenous binders, one or more exogenous binders that are tobacco exogenous binders, or combinations thereof, to aid in agglomeration of the particulate tobacco. Additionally or alternatively, the homogeneous tobacco material may consist of other additives, including but not limited to, tobacco and non-tobacco fibers, aerosol formers, wetting agents, plasticizers, flavorants, fillers, aqueous and non-aqueous solvents and combinations thereof. can

For example, when a rod according to the present invention is used as an aerosol-forming substrate in a heated aerosol-generating article, the sheet or cut filler of homogeneous tobacco material for use in forming the rod described herein may contain an aerosol former on a dry weight basis. The content may be between about 5% and about 30% by weight. Rods for use in electrically actuated aerosol-generating systems having a heating element preferably comprise at least about 5% to about 30% aerosol former. For rods for use in electrically actuated aerosol-generating systems having a heating element, the aerosol former may preferably be glycerin.

The rods described herein may consist of a collected sheet or cut filler of homogeneous tobacco material surrounded by a porous or non-porous wrapper.

Embodiments may further include organizing the first continuous sheet. For example, it may include crimping, embossing, penetrating or otherwise texturing the first continuous sheet before collecting the first continuous sheet together with the second continuous sheet.

In addition, when using cut filler, rods can be formed with cut filler by continuous feeding rather than continuous sheets.

The rod formed as above must maintain a certain hardness or higher in order to be made into a smokeable product to satisfy the desired quality.

Here, when a rod is manufactured using cut filler, the desired hardness can be adjusted through weight control, unlike using a sheet. Thus, it is possible to use only a smaller amount of plate leaf while maintaining a certain hardness, and in the case of an off-spec rod that may occur during the manufacturing process, cut filler can be reused.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a view illustrating an example in which a cigarette is inserted into a holder.

Referring to FIG. 1 , a cigarette 2 may be inserted into a holder 1 . When the cigarette 2 is inserted, the heater 130 is positioned inside the cigarette 2 . Accordingly, the aerosol-generating material of the cigarette 2 is heated by the heated heater 130 , thereby generating an aerosol.

The cigarette 2 may have a shape similar to that of a general combustion type cigarette. For example, the cigarette 2 may be divided into a first portion 210 including an aerosol generating material and a second portion 220 including a filter and the like.

The entire first part 210 may be inserted into the holder 1 , and the second part 220 may be exposed to the outside. Alternatively, only a portion of the first portion 210 may be inserted into the holder 1 , or portions of the first portion 210 and the second portion 220 may be inserted.

The user may inhale the aerosol while biting the second part 220 with the mouth. At this time, the aerosol is generated when the external air passes through the first part 210 , and the generated aerosol passes through the second part 220 and is delivered to the user's mouth.

External air may be introduced through at least one air passage formed in the holder 1 . Alternatively, external air may be introduced through at least one hole formed on the surface of the cigarette 2 .

2 is a configuration diagram illustrating an example of a cigarette.

Referring to FIG. 2 , the cigarette 2 includes a tobacco rod 210 , a first filter segment 221 , a cooling structure 222 and a second filter segment 223 . The first part described above with reference to FIG. 1 includes a tobacco rod 210 , and the second part includes a first filter segment 221 , a cooling structure 222 and a second filter segment 223 .

Referring to FIG. 2 , the cigarette 2 may be wrapped by wrappers 231 , 232 , 233 , 234 , 235 and 236 . For example, the tobacco rod 210 is wrapped by a first wrapper 231 , and the first filter segment 221 is wrapped by a second wrapper 232 . Further, the cooling structure 222 is wrapped by a third wrapper 233 , and the second filter segment 223 is wrapped by a fourth wrapper 234 .

The fifth wrapper 235 may be surrounded by the first wrapper 231 , the second wrapper 232 , and the third wrapper 233 . In other words, the tobacco rod 210 , the first filter segment 221 and the cooling structure 222 of the cigarette 2 may be further wrapped by the fifth wrapper 235 . In addition, the sixth wrapper 236 may be surrounded by at least a portion of the fifth wrapper 235 and the outside of the fourth wrapper 234 . In other words, at least a portion of the cooling structure 222 of the cigarette 2 and the second filter segment 223 may be further wrapped by the sixth wrapper 236 .

The first wrapper 231 , the second wrapper 232 , the fifth wrapper 235 , and the sixth wrapper 236 may be made of general wrapping paper. For example, the first wrapper 231 , the second wrapper 232 , the fifth wrapper 235 , and the sixth wrapper 236 may be porous or non-porous wrapping paper. For example, the thickness of the first wrapper 231 may be about 61 μm and the porosity may be about 15 CU, and the thickness of the second wrapper 232 may be about 63 μm and the porosity may be about 15 CU, but is not limited thereto. . In addition, the thickness of the fifth wrapper 236 may be about 66 μm and the porosity may be about 10 CU, and the thickness of the sixth wrapper 236 may be 66 μm and the porosity may be about 17 CU, but is not limited thereto.

In addition, an aluminum foil may be further included on the inner surface of the first wrapper 231 and/or the second wrapper 232 .

The third wrapper 233 and the fourth wrapper 234 may be made of hard wrapping paper. For example, the thickness of the third wrapper 233 may be about 158 μm and the porosity may be about 33 CU, and the thickness of the fourth wrapper 234 may be about 155 μm and the porosity may be about 46 CU, but is not limited thereto. .

A predetermined material may be internally added to the fifth wrapper 235 and the sixth wrapper 236 . Here, an example of the predetermined material may be silicon, but is not limited thereto. For example, silicon has properties such as heat resistance with little change with temperature, oxidation resistance without oxidation, resistance to various chemicals, water repellency to water, or electrical insulation. However, even if it is not silicon, any material having the above-described characteristics may be applied (or coated) to the fifth wrapper 235 and the sixth wrapper 236 without limitation.

The fifth wrapper 235 and the sixth wrapper 236 may prevent the cigarette 2 from burning. For example, when the tobacco rod 210 is heated by the heater 130, there is a possibility that the cigarette 2 is burned. Specifically, when the temperature rises above the ignition point of any one of the materials included in the tobacco rod 210, the cigarette 2 may be burned. Even in this case, since the fifth wrapper 235 and the sixth wrapper 236 include a non-combustible material, the burning phenomenon of the cigarette 2 can be prevented.

In addition, the fifth wrapper 235 may prevent the holder 1 from being contaminated by substances produced in the cigarette 2 . By the user's puff, liquid substances may be created in the cigarette 2 . For example, liquid substances (eg, moisture, etc.) may be generated by cooling the aerosol generated in the cigarette 2 by the outside air. As the fifth wrapper 235 wraps the tobacco rod 210 and/or the first filter segment 221 , liquid substances created within the cigarette 2 will be prevented from leaking out of the cigarette 2 . can Accordingly, the phenomenon that the inside of the holder 1 is contaminated by the liquid substances produced in the cigarette 2 can be prevented.

The diameter of the cigarette 2 is within the range of 5 mm to 9 mm, and the length may be about 45 mm, but is not limited thereto. For example, the length of the tobacco rod 210 is about 11.5 mm, the length of the first filter segment 221 is about 8 mm, the length of the cooling structure 222 is about 18.5 mm, and the length of the second filter segment 223 is about 18.5 mm. may be about 7 mm, but is not limited thereto.

The structure of the cigarette 2 shown in FIG. 2 is merely an example, and some components may be omitted. For example, the cigarette 2 may not include one or more of the first filter segment 221 , the cooling structure 222 , and the second filter segment 223 .

Tobacco rod 210 contains an aerosol generating material. For example, the aerosol generating material may comprise at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and oleyl alcohol.

The tobacco rod 210 may also contain other additive substances such as flavoring agents, wetting agents and/or organic acids. For example, flavoring agents include licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, sage, spearmint, ginger, coriander or coffee and the like. In addition, the wetting agent may include glycerin or propylene glycol, and the like.

As an example, the tobacco rod 210 may be filled with a reconstituent 　 tobacco sheet.

As another example, the tobacco rod 210 may be filled with cut filler. Here, tobacco cut fillers can be produced by cutting leaflet sheets.

As another example, the tobacco rod 310 may be filled with a plurality of tobacco strands in which the leaflet sheet is chopped. For example, the tobacco rod 310 may be formed by combining a plurality of tobacco strands in the same direction (parallel) to each other or randomly.

For example, the plate-like sheet may be manufactured by the following process. First, the tobacco raw material is pulverized to produce an aerosol-generating material (eg, glycerin, propylene glycol, etc.), a flavoring solution, a binder (eg, guar gum, xanthan gum, carboxymethyl cellulose (CMC), etc.), water After making a slurry in which the etc. are mixed, a plate-like sheet is formed using the slurry. When making the slurry, natural pulp or cellulose may be added, and one or more binders may be mixed and used. On the other hand, tobacco strands may be produced by cutting or shredding the dried leaf-leaf sheet.

The tobacco raw material may be tobacco leaf flakes, tobacco stems and/or tobacco fines generated during tobacco processing. In addition, the lamellar sheet may contain other additives such as wood cellulose fibers.

5% to 40% of the aerosol generating material may be added to the slurry, and 2% to 35% of the aerosol generating material may remain in the platelet sheet. Preferably, 5% to 30% of the aerosol generating material may remain in the leaflet sheet.

In addition, before the process in which the tobacco rod 210 is packaged by the first wrapper 231 , a flavoring liquid such as menthol or a moisturizer may be sprayed and added to the center of the tobacco rod 210 .

The first filter segment 221 may be a cellulose acetate filter. For example, the first filter segment 221 may be a tube-shaped structure including a hollow therein. The length of the first filter segment 221 may be an appropriate length within the range of 4 mm to 30 mm, but is not limited thereto. Preferably, the length of the first filter segment 221 may be 8 mm, but is not limited thereto.

The diameter of the hollow included in the first filter segment 221 may be an appropriate diameter within the range of 2 mm to 4.5 mm, but is not limited thereto.

When the first filter segment 221 is manufactured, the hardness of the first filter segment 221 may be adjusted by adjusting the content of the plasticizer.

In addition, the first filter segment 221 may be manufactured by inserting a structure such as a film or a tube made of the same or different material inside (eg, hollow).

The first filter segment 221 may be manufactured using cellulose acetate. Accordingly, when the heater 130 is inserted, the inner material of the tobacco rod 210 may be prevented from being pushed back, and a cooling effect of the aerosol may be generated.

The cooling structure 222 cools the aerosol generated by the heater 130 heating the tobacco rod 210 . Thus, the user can inhale the aerosol cooled to a suitable temperature.

The length or diameter of the cooling structure 222 may be variously determined according to the shape of the cigarette 2 . For example, the length of the cooling structure 222 may be appropriately employed within the range of 7 mm to 20 mm. Preferably, the length of the cooling structure 222 may be about 18.5 mm, but is not limited thereto.

The cooling structure 222 may be formed by a crimped polymer sheet. Here, the polymer sheet is selected from the group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA) and aluminum foil. It can be made of material. As the cooling structure 222 is formed by the crimped polymer sheet, the cooling structure 222 may include a plurality of channels extending in the longitudinal direction. Here, a channel means a passage through which a gas (eg, air or aerosol) passes.

For example, the cooling structure 222 may be formed from a material having a thickness of between about 5 μm and about 500 μm, such as between about 10 μm and about 250 μm. Also, the total surface area of the cooling structure 222 may be between ^{about 300 mm 2} /mm and about 1000 mm ^{2 /mm.} Further, the aerosol cooling element may be formed from a material having a specific surface area of between about 10 mm ² /mg and about 100 mm ^{2 /mg.}

Meanwhile, the cooling structure 222 may include a thread containing a volatile flavor component. Here, the volatile flavor component may be menthol, but is not limited thereto. For example, the thread may be filled with a sufficient amount of menthol to provide at least 1.5 mg of menthol to the cooling structure 222 .

The second filter segment 223 may be a cellulose acetate filter. The length of the second filter segment 223 may be appropriately employed within the range of 4 mm to 20 mm. For example, the length of the second filter segment 223 may be about 7 mm, but is not limited thereto.

In the process of manufacturing the second filter segment 223 , the flavor may be generated by spraying a flavoring liquid to the second filter segment 223 . Alternatively, a separate fiber to which the flavoring liquid is applied may be inserted into the second filter segment 223 . The aerosol generated by the tobacco rod 210 is cooled as it passes through the cooling structure 222 , and the cooled aerosol is delivered to the user through the second filter segment 223 . Accordingly, when the flavoring element is added to the second filter segment 223 , the effect of enhancing the durability of the flavor delivered to the user may occur.

3 is a view for explaining a rod filled with cut filler according to an embodiment.

3, the rod 210 is filled with cut filler. When the circumference of the rod is 22 mm and the length is 120 mm, the weight of the cut filler to maintain a constant hardness, that is, the hardness required to make a stick, is approximately 2,600 mg. In order to maintain the same hardness when using a plate leaf sheet according to the prior art rather than cut filler, when the circumference of the rod is 22 mm and the length is 120 mm, the plate leaf weight is approximately 3,000 mg. Therefore, when forming the rod using cut filler according to the embodiment, it is possible to reduce the use of the plate leaf by about 13% while maintaining the same hardness as the plate leaf. Here, the weight of the cut filler rod has been described as 2,600 mg, but is not limited thereto, and the weight of the cut filler rod may be appropriately applied within the range of 2300 mg to 2900 mg. Preferably, the hardness of the cigarette rod is 70 or more at the level of 2600 mg ± 300 mg. If the weight is too low or increased, the aerosol formation is non-uniform due to non-uniformity of heat transfer and airflow formation, and variations such as hardness and suction resistance of rod physical properties increase. In addition, although the weight of the cut filler rod has been described for the case where the circumference of the cigarette rod is 22 mm and the length is 120 mm, the range of weight may vary depending on the value of the cigarette rod. For example, if the length of the cigarette rod is 72mm, the weight of the platelet cut filler to maintain a constant hardness may be 1,560mg.

Depending on the weight of the rod, the physical properties of the rod, especially hardness and suction resistance, change. For example, if the rod weight is low, the suction resistance is lowered and the hardness is reduced, resulting in the loss of cut sheath at the end of the rod, non-uniform cut sheath arrangement, etc. .

On the other hand, when the weight of the rod is exceeded, it is difficult to achieve a uniform smoking quality due to an increase in suction resistance. Therefore, it is important to have an appropriate rod weight while maintaining the appropriate hardness required for stick manufacturing.

The test data of the rod weight, suction resistance, and hardness according to the embodiment are shown in Table 1 below.

load weight rod circumference resistance to suction Hardness 1,560mg (1320~1920mg) 22mm (20-25mm) 105mmH20 (70-180mmH2O) 80% (70-95%)

In an embodiment, while maintaining the same hardness as in the case of forming the rod from the plate-leaf sheet, when using cut filler, the rod can be manufactured with less weight. In addition, when forming the rod from the plate-leaf sheet, off-spec When this occurs, it is impossible to recycle the plate leaf, but when forming a rod with cut filler, even if off-spec occurs, the cut filler can be recycled and used when forming another rod.

Here, the angular width of the cut-off can be formed by using a certain angular width, for example, a cut-off between 0.5 and 1.3 mm.

In addition, it is possible to adjust the hardness of the rod by adjusting the weight or amount of cut filler filled in the rod.

Through the aerosol-forming rod manufacturing method according to the embodiment, compared to the prior art in which the rod was formed using the plate-like sheet, the weight or usage of the plate-leaf can be reduced, and the prior art forms the rod in a sheet state, so it is off-spec It was difficult to recycle when it occurred, but it is possible to reuse the used cut filler even if an off-spec occurs when forming a rod using cut filler.

A person of ordinary skill in the art related to this embodiment will understand that it can be implemented in a modified form within a range that does not deviate from the essential characteristics of the above description. Therefore, the disclosed methods are to be considered in an illustrative rather than a restrictive sense. The scope of the present invention is indicated in the claims rather than the foregoing description, and all differences within the scope equivalent thereto should be construed as being included in the present invention.
