Description

Cigar wrapper and heated smoking article comprising same

Technical Field

The present invention relates to cigar paper, heated smoking articles comprising the cigar paper and a method of manufacturing the cigar paper.

Background

There is increasing interest in heated smoking articles having a tobacco rod formed by filling the inside of a wrapper with a cigarette filler material comprising a tobacco material and an aerosol-generating substrate. The heated smoking article is a smoking article in which tobacco material is heated by an electric heater of a heating device, rather than burned, to deliver aerosol generated from a cigarette filler material to a user. As the electric heater, various shapes such as a blade shape, a rod shape, etc. are widely used, and the electric heater is inserted from the front end of the tobacco rod at the time of use, thereby attaching the tobacco rod to the heating device.

Cigars, on the other hand, are smoking articles made by rolling tobacco leaves, characterized in that the tobacco leaves are contained in a material that encases the tobacco material. Such cigar products have been continuously purchased by consumers who like cigar-specific fragrances, and thinner cigars such as cigarillos have also appeared due to the long smoking time of the cigars.

As described above, smoking articles including cigar tobacco in the wrapper have been favored, but there are limitations in the tensile strength of existing cigar papers when they are used in existing heated smoking articles.

Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description, a detailed description of the related known functions or configurations will be omitted when it is considered that the gist of the present invention is unnecessarily obscured. Also, terms used in the present specification to accurately describe the embodiments may be different according to the intention of a user, an operator, or a convention in the art to which the present invention pertains. Accordingly, the definition of terms should be based on the entire specification. Like reference symbols in the various drawings indicate like elements.

Throughout the specification, when it is stated that a certain component is "on" another component, it includes not only the case where one component is in contact with another component but also the case where another component is interposed between two components.

Throughout the specification, when a portion is stated as "comprising" a certain component, it is intended that the other component be included, but not excluded.

Throughout the specification, the terms "upstream" and "downstream" are defined as follows: when a user inhales outside air using a smoking article, the portion of air flowing from the outside to the inside of the smoking article is "upstream", and the portion of air flowing from the inside to the outside of the smoking article including a combustible heat source is "downstream". "upstream" and "downstream" are used to indicate relative positions or orientations between portions of the smoking article.

Cigar paper for combustion smoking articles has a tensile strength of 80cN/mm or less and breakage of the paper when applied to heated smoking articles. In the process of producing a finished tobacco paper by including cigar tobacco leaves, it is difficult to achieve uniform proportioning, and after a primary process of producing a tobacco sheet, it is also necessary to prepare pulp by a secondary process, so that it is very inconvenient to perform two processes. In addition, during the execution of the corresponding process, the components contained in the cigarette paper are lost, and the peculiar taste of cigars is reduced.

To this end, the present invention developed cigar paper that can be smoked using a heated smoking device while maintaining the unique taste and flavor of cigars.

The cigar wrapper and the smoking article comprising the same according to the invention will now be described in detail with reference to the examples and the accompanying drawings. The present invention is not limited to the following examples.

The present invention provides cigar wrapper which is a cigar wrapper for wrapping smoking articles, the cigar wrapper comprising more than 50% by weight cigar tobacco leaves, the smoking articles being heated smoking articles.

According to an embodiment of the invention, the cigar wrapper contains more than 50% by weight cigar tobacco leaves. Thus, the smoking article of the present invention is capable of having cigar-specific smoke and taste. When the content of the cigar tobacco leaves is less than 50 weight percent, the peculiar smell and taste of cigar are insufficient, and the nicotine transfer is affected. More preferably, from 50 to 66% by weight of cigar tobacco leaves may be included.

According to an embodiment of the invention, the cigar paper has a tensile strength of 120cN/mm or more. Thus, the cigar wrapper may be suitable for use in a heated smoking article. Since the cigar paper has a tensile strength of 120cN/mm or more, when applied to smoking articles, breakage phenomenon does not occur during the process, and workability can be greatly improved. When the tensile strength is less than 120cN/mm, the workability is greatly reduced, and breakage may occur when the material is used in a heated type smoking device.

According to an embodiment of the invention, the cigar wrapper has a weight of 40 to 80g/m ² Is based on the weight of the substrate. When the basis weight of the cigar paper is lower than 40g/m ² Insufficient to support and retain shape of other materials of the smoking article; when it exceeds 80g/m ² In this case, as the elasticity of paper increases, problems such as insufficient adhesion and the like occur in the production of smoking articles, and the process cannot be successfully completed, thereby deteriorating the workability.

According to an embodiment of the invention, the cigar paper has a thickness of 50 to 180 um. When the cigar paper is less than 50um thick, it is insufficient to support other materials of the smoking article and retain shape; when the thickness exceeds 180 μm, problems such as insufficient adhesion and the like occur in manufacturing a smoking article, and the workability is lowered as the elasticity of the paper increases.

According to an embodiment of the invention, the cigar paper has an elongation of 0.5 to 3%. When the elongation of the cigar paper is lower than 0.5%, breakage occurs during the manufacture of the smoking article, and the processability is affected; when the elongation exceeds 3%, it is insufficient to support other materials of the smoking article and maintain the shape due to the excessive elongation.

According to an embodiment of the invention, the cigar paper has a porosity of 20 to 80 CU. The porosity is shown as Coresta units (Coresta Unit, CU), meaning that the porous material passes 1cm at a pressure of 1kPa ² Air volume flow value (cm) of sample ³ /cm ² Min at 1 kPa). When the porosity of the cigar paper is below 20CU (cm) ³ /cm ² Min at 1 kPa), external air cannot flow well when the smoking article is used, which may affect the taste during smoking; when the porosity exceeds 80CU (cm) ³ /cm ² Min at 1 kPa), excessive air inflow due to excessive porosity may reduce the smoking property (smoking quality) of the smoking article, and a problem of empty smoking may occur. More preferably, the cigar of the inventionThe smoking article has a good taste when the paper has a porosity of 50CU to 80 CU.

According to an embodiment of the invention, the cigar paper has a Surface Smoothness (SS) of 5 to 15 and a back smoothness (RS) of 5 to 15. When the Surface Smoothness (SS) of the smoking article is less than 5, the processability is lowered; when it exceeds 15, preference is lowered due to lack of characteristic features of cigar tobacco leaves. When the back surface smoothness (RS) is less than 5, the adhesive is not easily applied when the smoking article is manufactured, resulting in a problem that the adhesive breaks; when the number exceeds 15, the cut tobacco tends to slip, and there is a lack of uniformity in packaging the cut tobacco.

The Smoothness is measured by the method of the brookfield method (Bekk Smoothness), which measures the air flow between the paper and the ideal plane, the greater the number per unit time (seconds) the smoother. The cigar paper is different from the common paper in that the smoothness of the cigar tobacco leaves is lower than that of the common paper, but when the smoothness is lower than 5, the cigar paper can be blocked when a smoking article is manufactured, and the processability is reduced; when it exceeds 15, preference is lowered due to lack of characteristic features of cigar tobacco leaves.

According to an embodiment of the invention, the cigar paper is made by mixing pulp components with cigar leaves. The pulp component of the cigar paper may include one or more of hard pulp (hardwood pulp) and soft pulp (softwood pulp). The pulp may include only one of the hard pulp and the soft pulp, or may be in the range of 0.1 to 99.9:99.9 to 0.1, preferably, may be mixed in a weight ratio of 20 to 80: the weight ratio of 80 to 20 mixes the hard slurry and the soft slurry. Within the preferred ranges, there may be a tensile strength suitable for use in a heated smoking article. The more the contained hard pulp is, the larger the tensile strength is, but the problem that the elongation is increased and cigar tobacco leaves fall off is solved; conversely, when the more soft pulp is contained, the problems of elongation and drop of cigar tobacco leaves are reduced, but the tensile strength is also reduced, so that the reasonable proportion is suitable.

The cigar leaves used for the cigarette paper are mainly cigar leaf main veins, and almost no cigar leaf tongue is included. The cigar leaf main vein is included to be 90% by weight or more with respect to the whole of 100% by weight of cigar leaf, and the cigar leaf tongue is less than 1% by weight, substantially including almost no cigar leaf tongue.

According to an embodiment of the invention, the cigar wrapper may comprise a print of a leaf-stem shape similar to cigars. The printing method is not particularly limited as long as it is applicable to smoking articles.

According to a further embodiment of the invention, there is provided a method of manufacturing cigar wrapper wrapped around a smoking article, comprising the steps of: pulping cigar tobacco leaves (step S1), pulping paper pulp (step S2), and mixing cigar tobacco leaves subjected to pulping treatment in the steps S1 and S2 with the paper pulp (step S3); making paper from the mixed cigar tobacco leaves and paper pulp (step S4); the smoking article is a heated smoking article.

According to a further embodiment of the present invention, the steps S1 and S2 may be separately performed. In the invention, after the step S1 and the step S2 are independently executed, cigar tobacco leaves which are respectively pulped are mixed with paper pulp in the step S3, so that uniform proportioning can be realized, and the processing convenience can be improved and the processing time can be shortened due to simple procedures.

In addition, as the beating treatment is carried out independently, the dissolution of nicotine from cigar tobacco leaves can be reduced, and the nicotine transfer amount of the smoking product can be improved.

The manufacturing method of the present invention can be realized by a usual papermaking process. The usual papermaking process is performed by the sequence of a pulping process, a preparing process, a papermaking process, a processing process and a paper forming process.

The pulping process is a process of separating fibers from wood or other fiber plants by mechanical, chemical treatment, or the like; the preparation step is a step of preparing a material required in the papermaking step, and is performed by dissociation, beating, screening, and a part of the material is subjected to a drug treatment to be used in the papermaking step.

Such pulp is obtained by cutting logs into uniform sizes, peeling them in a barker (barker), grinding them in a mill (grinder) together with water, and screening (screen) for impurities.

The papermaking process is a process of papermaking the paper stock screened in the preparation process, and the papermaking process simply comprises the following steps: making paper sheets by uniformly spraying and dispensing the paper stock; mechanically compressing and dehydrating the sheet-like paper material through a compression roller; drying the sheet paper material by utilizing steam; after the thickness of the paper is adjusted by the roller and the surface is smoothed, the paper is subjected to a subsequent continuous process or is processed by a separate processing apparatus. The coiling can also be performed after drying or calendaring without the processing procedure.

In this case, the papermaking process may be classified into fourdrinier papermaking and cylinder papermaking. In the process of forming the paper layer, the wire section is a fourdrinier wire machine when formed as an endless wire, and the wire section is a cylinder wire machine when formed as a cylindrical wire.

According to another embodiment of the invention, the papermaking process of step S4 may be performed using a fourdrinier or a cylinder machine. Although both cylinder and fourdrinier wires may be used, cylinder paper machines are preferred to make the cigarette paper more efficient.

According to another embodiment of the invention, after the completion of the paper making process of step S4, a step S5 of calendering cigar paper may be further included. The calendering is performed off-line or on-line, by which the printability and the tensile strength can be improved.

According to another embodiment of the invention, a step S6 of printing the leaf stalk shape may be further included after said step S5. The printing method is not particularly limited as long as it is applicable to smoking articles.

Also, the invention may provide a smoking article comprising said cigar wrapper.

According to another embodiment of the invention there is provided a smoking article comprising: a smoking material portion, a cooling portion downstream of the smoking material portion, and a filter rod portion downstream of the cooling portion; also included are smoking articles of cigar wrapper wrapped around the smoking article. "smoking article" in the present invention refers to any product capable of smoking or any product that provides a smoking experience. In the present invention, the smoking article is particularly a smokable article that generates an aerosol, such as a heated e-cigarette.

According to another embodiment of the invention, the smoking material section, the cooling section downstream of the smoking material section and the filter rod section downstream of the cooling section may be connected in the length direction. That is, the filter rod portion is located most downstream of the smoke-absorbing substance portion, i.e., in the direction closest to the smoker (downstream direction); the smoking material section is located at the most upstream position with respect to the smoker, i.e., in the direction furthest from the smoker (upstream direction).

According to a further embodiment of the invention, the smoking material part comprises an aerosol generating substance. The aerosol-generating substance refers to a substance that can generate an aerosol (aerosol) and may be a liquid or a solid.

For example, the solid aerosol-generating substance may comprise a solid substance based on a tobacco material of reconstituted tobacco, cut tobacco, reconstituted tobacco, or the like. In particular, the smoking material portion of the smoking article of the invention may comprise cigar tobacco leaf as the solid material.

The liquid aerosol-generating substrate may comprise a liquid composition based on nicotine, cigarette extract and/or a plurality of flavourants. The scope of the invention is not limited to the examples listed above.

More specifically, the liquid aerosol-generating substance may include at least one of Propylene Glycol (PG) and Glycerin (GLY), and may further include at least one of ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. As another example, the aerosol-generating substance may further comprise at least one of nicotine, moisture and a flavour substance. As yet another example, the aerosol-generating substance may also include various additives such as cinnamon, capsaicin, and the like. Aerosol-generating substances may include not only liquid substances that are highly fluid but also gel-like or solid powdered substances. As described above, different constituent components of the aerosol-generating substance may be selected according to the embodiment, and the constituent proportions may also be adjusted according to the embodiment. In the following description, liquid may refer to a liquid aerosol-generating substance.

According to a further embodiment of the invention, the smoking material portion may comprise a solid aerosol-generating substance, or may comprise both a solid aerosol-generating substance and a liquid aerosol-generating substance. The length of the smoking material portion may be about 15mm to 75mm.

According to an embodiment of the invention, the smoking article comprises a mouthpiece portion. For example, the mouthpiece may be a single-body filter rod, a two-body filter rod, or a three-body filter rod. The mouthpiece portion may include at least one of a porous matrix filter rod, a tubular filter rod, and a paper tube (paper tube) filter rod. The filter rod may include a filter tow that may include a fibrous phase, a filament phase, or both, the fibrous phase including at least one of a polymer, paper, cellulose acetate, activated carbon, and carbon. But is not limited thereto. In some embodiments, the filter rod material may also include at least one of carbon-bearing adsorbents, activated carbon, and like filter materials known in the art. The mouthpiece portion may further include a tipping paper and/or a plug wrap wrapping the filter plug, and the tipping paper and the plug wrap are exemplified by, but not limited to, paper materials.

The filter rod portion may be made to produce a flavour. As an example, the flavoring agent may be sprayed onto the filter rod portion, or a separate fiber coated with the flavoring agent may be inserted into the filter rod portion.

And, the filter rod portion may comprise at least one capsule. Here, the capsule may function to generate a fragrance or may function to generate an aerosol. For example, the capsule may be a structure in which a liquid containing a perfume is enclosed with a coating film. The capsule may be spherical or cylindrical, but is not limited thereto.

The cooling portion may be made of a polymer material or a biodegradable polymer material. For example, the cooling part may be manufactured using only pure polylactic acid, but is not limited thereto. Alternatively, the cooling portion may be made of a cellulose acetate filter rod having a plurality of holes therethrough. However, the cooling portion is not limited to the above example, as long as the aerosol can be cooled.

In another aspect, the smoking article of the invention may further comprise a front end filter rod. The front end filter rod is located on the side of the smoking article opposite the filter rod portion. The front filter rod prevents the smoking material portion of the smoking article from coming out and prevents aerosol liquefied by the smoking article from flowing into the heated smoking device during smoking.

An exemplary heated smoking device that may use the smoking articles of the embodiments of the present disclosure is briefly described below.

The heated smoking device may include a housing, a heater, a control portion, and a battery.
