Aerosol Generating Article {AEROSOL GENERATING ARTICLE}

The present invention relates to aerosol-generating articles.

In recent years, there is an increasing demand for alternative products that overcome the disadvantages of traditional combustion cigarettes. As one of these alternative articles, for example, a device that generates an aerosol by electrically heating a cigarette stick (or aerosol-generating article) (eg, a cigarette-type electronic cigarette), a cartridge filled with a liquid containing tobacco components. There is a device (for example, a liquid electronic cigarette) that generates an aerosol by electrically heating the liquid supplied from the cartridge.

While traditional cigarettes have disadvantages due to combustion, combustion-type traditional cigarettes have the advantage of being consumed for a long period of time, so that consumers' familiarity with and satisfaction with smoking are high. Therefore, research on alternative products is being actively conducted in a direction that can overcome the disadvantages while preserving the advantages of conventional combustion-type cigarettes. Among alternative products, cigarette-type electronic cigarettes may have a high level of familiarity with smoking in that only the heating method of the cigarette is changed while maintaining the shape of a traditional cigarette, but the satisfaction with smoking still needs improvement.

Accordingly, the present inventors have completed the present invention by continuously researching to compensate for the disadvantages of cigarette-type electronic cigarettes, such as the feeling of satisfaction for smoking.

In the present specification, an aerosol-generating article may be an article including an aerosol-generating substrate capable of generating an aerosol inhalable by a user by heating or the like. As used herein, an aerosol-generating device may be an aerosol-generating device using an aerosol-generating article to generate an aerosol inhalable directly into the user's lungs through the user's mouth. For example, the aerosol-generating device may be a holder. The aerosol-generating article and aerosol-generating device may include several segments each having a functional function, which segments are referred to herein as "... It is marked as “Part”.

In this specification, the terms "upstream" and "downstream" are terms used to indicate the relative position of the segments that make up the aerosol-generating article relative to the direction in which the user draws air with the aerosol-generating article. The aerosol-generating article includes an upstream end (ie, the portion through which the air enters) and an opposite downstream end (ie, the portion through which the air exits). When using the aerosol-generating article, the user may bite the downstream end of the aerosol-generating article. The downstream end is located downstream of the upstream end, while the term “end” may also be described as “end”.

The present invention relates to an aerosol-generating article, and according to one embodiment of the present invention, the aerosol-generating article includes a first aerosol-generating part and a second aerosol-generating part. For reference, FIG. 1 provides a diagram illustrating an aerosol-generating article according to one embodiment of the present invention. The first aerosol generating unit 11 is located at the most upstream from the aerosol generating article 10, so air entering from the upstream end of the aerosol generating article first passes through the first aerosol generating unit. The second aerosol generating unit 12 is disposed on one side of the first aerosol generating unit 11, and the other side where the second aerosol generating unit is not disposed naturally becomes an upstream end of the aerosol generating article 10.

The first aerosol generating unit 11 includes a leaf sheet, and the second aerosol generating unit 12 includes a cigarette cut filler, so that the first aerosol generating unit and the second aerosol generating unit are structurally differentiated. . Both the sheet leaf sheet in the first aerosol generating unit 11 and the tobacco cut filler in the second aerosol generating unit 12 are impregnated with an aerosol generating composition, so that aerosols can be generated by means such as heating. .

The leaf lamina sheet is a sheet made from particulate tobacco obtained by grinding or pulverizing one or both of leaf lamina and tobacco leaf stem. The platelet sheet may be manufactured by a papermaking method, a rolling method, a slurry method, etc. according to a manufacturing method, and the platelet sheet manufactured according to each manufacturing method has a difference in internal structure or physical properties. The papermaking method is to separate fibers and extracts from the above-described particulate tobacco raw material by using extraction, and then process the separated fibers into a paper form to manufacture a sheet. The slurry method is the above-described particulate tobacco A sheet is manufactured by mixing a phosphorus raw material with a specific solvent to prepare a slurry and then injecting the slurry. Since a number of nicotine components are separated from the fibers and included in the extract during extraction in the papermaking method, the final sheet is prepared by preparing a sheet and then coating the concentrated solution of the separated extract again.

According to one embodiment of the present invention, the platelet sheet included in the first aerosol generator 11 is a platelet sheet manufactured by a papermaking method and a slurry method parallel method. According to one embodiment of the present invention, the paper-making method and the slurry-type parallel method start with the paper-making method to prepare a sheet, then pulverize the prepared sheet again without coating the concentrated solution of the separated extract, and then according to the slurry-type method This is a method of preparing a slurry by mixing it with a specific solvent and then injecting it to produce a sheet. Similar to the paper-type sheet sheet, the sheet sheet manufactured by the parallel method of papermaking and silery type can be impregnated with a large amount of the aerosol generating composition, and similar to the slurry-type sheet sheet, the component uniformity within the sheet sheet can be improved. It can be suitable as a material for the first aerosol generator 11 in that it can be secured. In addition, since components such as nicotine extracted in the papermaking method are not coated on the sheet again, when used in the first aerosol generator 11, the nicotine content can be minimized while improving the flavor of tobacco. According to one embodiment of the present invention, the platelet sheet contains 100ppm to 3000ppm, specifically 200ppm to 2000ppm, more specifically 300ppm to 1000ppm of nicotine based on the weight of the platelet sheet. The nicotine content is significantly lower than the nicotine content of leaf leaves used in the second aerosol generating unit, and this may add flavor when nicotine is transferred in the second aerosol generating unit.

Since the nicotine content is not high in that the leaf blade and tobacco petiole are used as raw materials, the segment for the main purpose of nicotine transfer, in this specification, when used in the second aerosol generator 12, the leaf leaf sheet contains tobacco. One or more of tobacco dust, tobacco fines and other particulate tobacco by-products formed during processing, handling and shipping may be added. Unlike this, since the first aerosol generating unit 11 is a segment whose main purpose is aerosol generation rather than nicotine transfer, the second aerosol generating unit only uses a small amount of nicotine contained in the sheet leaf raw material without additionally adding tobacco components. Together with the nicotine of (12), the flavor of tobacco can be improved.

The second aerosol generator 12 includes a cigarette cut filler. The tobacco cut filler may be produced by shredding tobacco sheets (or slurry-type leaflet sheets). Unlike the first aerosol generating unit 11, the second aerosol generating unit 12 has a main purpose of nicotine transfer, so rather than containing a large amount of the aerosol generating composition, the nicotine content is increased so that the first aerosol generating unit 11 It is important to ensure that a sufficient amount of nicotine is delivered to the resulting aerosol. Considering such functionality, a slurry-type platelet sheet according to a slurry-type method may be preferably used as a sheet-like sheet that can be used in the second aerosol generating unit 12 rather than a paper-type platelet sheet according to a paper-making method. When using the slurry leaflet sheet, one or more of tobacco dust, tobacco fines and other particulate tobacco by-products formed during processing, handling and shipping of tobacco may be added to increase the nicotine content.

The first aerosol generating unit 11 fills the sheet-like raw material, and the second aerosol generating unit 12 fills the raw material in the shape of a cut filler, so basically the second aerosol generating unit 12 is filled with cigarettes. The platelet sheet filled in the first aerosol generating unit 11 blocks the cut sheath from being released to the outside, so that the stability of the overall structure of the aerosol generating article 10 is improved. Since the second aerosol generating unit 12 filled with the raw material in the form of a corner shell can form a more complicated flow path in the flow of aerosol or air than the first aerosol generating unit 11 filled with the raw material in the form of a sheet, nicotine Functionality in implementation can be improved.

The first aerosol generating unit 11 impregnates a larger amount of the aerosol generating composition than the second aerosol generating unit 12 due to a difference in functionality. According to one embodiment of the present invention, the composition for generating aerosol in the first aerosol generating unit 11 is 10% to 50% by weight, specifically 15% to 45% by weight based on the weight of the leaf sheet, More specifically, 20% by weight to 40% by weight is impregnated into the planar sheet. In this specification, since the content of the aerosol generating composition added to the first aerosol generating unit 11 and the like is evaluated based on the aerosol generating article, it means a dry state. When the aerosol generating composition is impregnated in an amount exceeding the above range, the aerosol generating composition may leak due to exceeding the storage capacity of the sheet sheet of the first aerosol generating unit, and when the aerosol generating composition is impregnated in an amount below the above range, The amount of aerosol generated at the most upstream of the aerosol-generating article is insufficient, which is undesirable because functionality such as nicotine transfer may be deteriorated.

According to one embodiment of the present invention, the aerosol generating composition in the second aerosol generating unit 12 is 1% to 25% by weight, specifically 3% to 20% by weight based on the weight of the tobacco cut filler, more Specifically, 5% to 15% by weight is impregnated into the tobacco cut filler. When the aerosol generating composition is impregnated in excess of the above range, the concentration of nicotine in the aerosol is lowered due to generation of an excessively large amount of aerosol, and thus the user's feeling of satisfaction in smoking may decrease, and the aerosol generating composition is impregnated below the above range. If it is, the amount of nicotine, etc., that can be implemented by directly contacting the aerosol generating composition with tobacco cut filler may be reduced, making it inefficient in implementing nicotine.

In order to secure functionality in the aerosol-generating article 10, the volumes of the first aerosol-generating unit 11 and the second aerosol-generating unit 12 may be adjusted. According to one embodiment of the present invention, the first aerosol generator 11 is 70% to 100% by volume, specifically 75% to 100% by volume, more specifically, based on the second aerosol generator 12 80% by volume to 100% by volume. When the volume of the first aerosol generating unit 11 exceeds the above range, more aerosols may be generated even if nicotine transfer and the user's satisfaction with smoking are taken into account, so the aerosol-generating article 10 may unnecessarily increase in size. , and when the volume of the first aerosol generating unit 11 is less than the above range, the amount of aerosol generation may not be sufficient.

The aerosol-generating composition may include a moisturizing component. The moisturizing component maintains moisture in the aerosol generated when heating the aerosol-generating article 10 at an appropriate level, thereby softening the original taste of tobacco and enriching the amount of smoke. According to one embodiment of the present invention, the moisturizing component is glycerin, propylene glycol, water or a combination thereof. In order to enhance the functionality of the moisturizing component, at least one of ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and oleyl alcohol may be further added.

In the aerosol-generating composition, the moisturizing component may be appropriately adjusted in consideration of the above-described functionality. According to one embodiment of the present invention, the moisturizing component is 50% to 99% by weight, specifically 65% to 95% by weight, more specifically 80% to 90% by weight based on the weight of the composition for generating an aerosol. is included in the aerosol-generating composition. When the moisturizing component is included in an amount exceeding the above range, it is difficult to be easily impregnated into a substrate such as a platelet sheet or tobacco cut filler in terms of physical properties of the aerosol generating composition, and when the moisturizing component is included below the above range, basically nicotine, etc. Not only is the functionality for the implementation of cigarettes degraded, but the moisture content in the aerosol is low, making it difficult for the unique taste of tobacco to be smoothly delivered to the user.

The aerosol-generating composition may include a binding component. The binding component helps other components other than the binding component in the aerosol-generating composition to be impregnated into a base material such as a leaf sheet sheet or tobacco cut filler in a larger amount. Natural gum may be used as the binding component in consideration of the fact that the aerosol-generating composition component is actually inhaled into the human body. According to one embodiment of the present invention, the binding component is guar gum, gum arabic or a combination thereof.

In the aerosol-generating composition, the binding component may be appropriately adjusted in consideration of the above-described functionality. According to one embodiment of the present invention, the binding component is 1% to 40% by weight, specifically 3% to 25% by weight, more specifically 5% to 15% by weight based on the weight of the aerosol-generating composition. is included in the aerosol-generating composition. When the binding component is included in an amount exceeding the above range, the content of other components such as a moisturizing component is relatively reduced, so that the content of moisture in the aerosol may be insufficient, and when the binding component is included below the above range, the aerosol generating composition Physical properties It is difficult to be easily impregnated into substrates such as sheet leaf sheets or tobacco cut filler.

The aerosol-generating composition may include a flavoring component. The flavoring component may provide an appropriate flavor or flavor according to the user's preference. The flavoring component may include perfume, flavoring agent, and the like. The fragrance may include menthol, peppermint, spearmint oil, various fruit flavor components, etc., but is not limited thereto. The flavoring agent is not particularly limited as long as it can provide various flavors or flavors to the user and is generally used in the art.

In the aerosol-generating composition, the flavoring component may be appropriately adjusted in consideration of the above-described functionality. According to one embodiment of the present invention, the flavor component is 1% to 30% by weight, specifically 1.5% to 20% by weight, more specifically 2% to 10% by weight based on the weight of the aerosol generating composition are included in the composition. When the flavoring component is included in an amount exceeding the above range, the content of other components such as moisturizing components is relatively reduced, and thus the content of moisture in the aerosol may be insufficient, and user's preference may rather decrease due to strong flavor or flavor. When the flavor component is included in an amount less than the above range, a change in flavor or flavor due to the addition of the flavor component may be insignificant.

The aerosol-generating article 10 according to one embodiment of the present invention may further include a first filter unit 13 and a second filter unit 14. The first filter unit 13 is disposed on one side (downstream side) of the second aerosol generating unit 12, and the second filter unit 14 is disposed on one side (downstream side) of the first filter 13. do. When the aerosol generating article 10 is composed of a first aerosol generating unit 11, a second aerosol generating unit 12, a first filter unit 13, and a second filter unit 14 as shown in FIG. 1, An aerosol generating device 20, which will be described later, generates an aerosol by heating at least a portion of the first aerosol generating unit 11 and the second aerosol generating unit 12, and the generated aerosol is generated by the first filter unit 13 and the second aerosol generating unit 12. It can pass through two filter units 14 in turn and be delivered to the user.

The first filter unit 13 and the second filter unit 14 basically have a function of filtering a specific component from the aerosol while passing the aerosol. In the case of the first filter unit 13, since it is located where the aerosol heated from the first aerosol generating unit 11 and the second aerosol generating unit 12 passes first, a function capable of additional cooling is required. It can also be referred to as a cooling part in that it becomes. Accordingly, the user can inhale the aerosol cooled to an appropriate temperature.

The first filter unit 13 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 material can be made. As the first filter unit 13 is formed by the crimped polymer sheet, the first filter unit 13 may include a plurality of channels extending in the longitudinal direction of the aerosol-generating article 10 . Here, the channel means a passage through which gas (eg, air or aerosol) passes. According to one embodiment of the present invention, the first filter unit 13 may be made of pure polylactic acid or a combination of other degradable polymers and polylactic acid.

The first filter unit 13 may include a thread containing a volatile flavor component. Here, the volatile flavor component may be menthol, but is not limited thereto. For example, a sufficient amount of menthol may be filled in the thread to provide menthol to the first filter unit 13 .

The second filter unit 14 may be a cellulose acetate filter. For example, the second filter unit 14 may be made of a recess filter, but is not limited thereto. In the process of manufacturing the second filter unit 14, flavoring liquid may be sprayed onto the second filter unit 14 to generate flavor. Alternatively, a separate fiber coated with flavoring liquid may be inserted into the second filter unit 14 . The aerosol generated by the first aerosol generating unit 11 and/or the second aerosol generating unit 12 is cooled as it passes through the first filter unit 13, and the cooled aerosol passes through the second filter unit 14. delivered to the user through Therefore, when a flavoring element is added to the second filter unit 14, the effect of enhancing the persistence of the flavor delivered to the user may occur. In addition, at least one capsule may be included in the second filter unit 14 . Here, the capsule may have a structure in which an internal liquid containing a fragrance is wrapped with a film. For example, the capsule may have a spherical or cylindrical shape, but is not limited thereto.

Although not shown, the aerosol-generating article 10 may further include a shear plug. The front end plug may be located on the upstream end side of the first aerosol generator 11 . The front end plug can prevent the first aerosol generating unit 11 from escaping to the outside, and can prevent the aerosol liquefied from the first aerosol generating unit 11 from flowing into the aerosol generating device 20 during smoking. there is.

Although not shown, the aerosol-generating article 10 may be wrapped by a wrapper. For example, the first aerosol generating unit 11 may be wrapped by a first wrapper, and the second aerosol generating unit 12 may be wrapped by a second wrapper. Also, the first filter unit 13 may be wrapped by a third wrapper, and the second filter unit 14 may be wrapped by a fourth wrapper. In addition, the thermally conductive wrapper may be wrapped around the first wrapper and the second wrapper. In other words, the first aerosol generating part 11 and the second aerosol generating part 12 of the aerosol generating article 10 may be further wrapped by a thermally conductive wrapper.

The thermally conductive wrapper surrounds at least a portion of the first aerosol generator 11 and the second aerosol generator 12 . For example, the thermally conductive wrapper may be a metal foil such as aluminum foil, but is not limited thereto. For example, the thermally conductive wrapper can be made from paramagnetic materials such as aluminum, platinum, rutinium, and the like. The thermally conductive wrapper surrounding the first aerosol generating unit 11 and the second aerosol generating unit 12 generates the first aerosol generating unit 11 and the second aerosol by the heater unit 23 of the aerosol generating device 20. The heat transferred to the unit 12 can be evenly distributed to improve the thermal conductivity applied to the first aerosol generator 11 and the second aerosol generator 12, and accordingly, the first aerosol generator 11 And the flavor of the aerosol generated from the second aerosol generator 12 can be improved.

For example, when the aerosol-generating article 10 is inserted into the aerosol-generating device 20, the heater unit 23 may be located outside the aerosol-generating article 10. Thus, the heated heater section 23 can increase the temperature of the aerosol-generating material in the aerosol-generating article 10 .

According to one embodiment of the present invention, the heater unit 23 may be configured as an electrical resistive heater. For example, the heater unit 23 may include an electrically conductive track, and the heater unit 23 may be heated as current flows through the electrically conductive track. However, the heater unit 23 is not limited by the above-described example, and may be applicable without limitation as long as it can be heated to a desired temperature.

An aerosol-generating article was manufactured in the same manner as in Example 1, except that the first aerosol-generating part was made of cellulose acetate in the same way as the second filter part.

Comparative Example 2

An aerosol-generating article was manufactured in the same manner as in Example 1, except that the second aerosol-generating part was extended and applied in place of the first aerosol-generating part without the first aerosol-generating part in the aerosol-generating article.

Experimental example

By burning the cigarettes according to Example 1, Comparative Example 1 and Comparative Example 2, Total Particulate Matter (TPM), Tar, Nicotine, Propylene Glycol (PG), Glycerine , GLY) and water components (mg / stick) were measured and shown in Table 1 below. Specifically, the experiment was conducted in a smoking room with a temperature of about 22 ± 2 ° C and a humidity of about 60 ± 5% by applying each cigarette sample to an aerosol generating device, inhaling 55 ml for 3 seconds and waiting for 27 seconds. A total of 14 puffs were performed under CRM81 conditions, a standard measurement method for electronic cigarettes, and aerosols generated for each cigarette sample were collected and analyzed. The total particulate matter (TPM) is a value obtained by measuring the weight change of cigarettes after smoking using the smoking device, and the contents of the remaining components were confirmed by analyzing the collected smoke by GC (Gas Choromatography). Here, in the case of tar, the total particulate matter (TPM) was calculated by subtracting the amount of water and nicotine.

Example 1 Comparative Example 1 Comparative Example 2 TPM (mg/stick) 79.2 53.4 41.5 Tar (mg/stick) 47.1 31.4 25.3 Nicotine (mg/stick) 0.99 0.79 0.89 Propylene glycol (mg/stick) 7.02 3.88 5.21 Glycerin (mg/stick) 14.53 5.59 5.41 Moisture (mg/stick) 31.2 21.1 15.3

According to Table 1, when the platelet impregnated with the aerosol generating composition was introduced into the first aerosol generator as in Example 1, Comparative Example 1 in which cellulose acetate was introduced at the same position and the first aerosol generator without the first aerosol generator were introduced. Compared to Comparative Example 2, in which the two aerosol generators were extended and introduced, it was confirmed that a significantly larger amount of aerosol corresponding to the total particulate matter was generated, and the amount of atomization was excellent.

In addition, the platy leaf sheet constituting the first aerosol generating unit of Example 1 basically contains a small amount of nicotine, and the first aerosol generating unit introducing the platy leaf impregnated with the aerosol generating composition transfers components such as nicotine. Since a large amount of propylene glycol, glycerin, moisture, etc. can be generated, not only nicotine but also a large amount of tar components other than nicotine can be contained to enhance the flavor of tobacco.
