Until now, the general cigarette has been in the form of burning the tobacco leaf of the tobacco end of the cigarette, the contents of the pyrolysis, synthesis and distillation of the components to bend in the form. At this time, by burning, all organic matter including leaf tobacco and fragrance substances are burned away at high temperature. Smokers choose the right product for their individual smoking habit, depending on the total amount of pyrolysis produced and also the direction and taste of their favorite flavors.

When burning this type of cigarette, the temperature may vary depending on the contents of mixed leaf mixture inside the cigarette, but the temperature ranges from 700 ° C to 950 ° C. However, the type of tobacco which is inhaled by the combustion method is decomposed or synthesized by high heat depending on the composition of the mixed leaf tobacco and the mixture of fragrances and other substances, and releases more than 4000 kinds of compounds, which are inhaled by smokers. It is known to cause bad tobacco taste, which has many health problems and irritations.

Accordingly, there has been a demand for an improved alternative cigarette by a new heat transfer method that greatly reduces the harmful components of conventional cigarette-type cigarettes, while maintaining the smoking taste such as aroma and aerosol delivered to the smoker.

New cigarettes by indirect heating with electrical energy rather than direct combustion can significantly reduce the chemicals found in conventional cigarettes, deliver them without destroying fragrances, have different inhalation functions, and without compromising the right to smoke. It is emerging as a next-generation cigarette technology that can satisfy individual preferences.

In general, a heated cigarette produces aerosols by inhaling heated air without generating carbonaceous smoke, a common product that is produced during the combustion of the cigarette. do.

The electrically heated cigarette was first released by Philip Morris, and its technology is disclosed. Among these, the flavor delivery mechanism of US Patent Application No. 89-444746, which is a relatively early model and uses electricity as a heating source, is as follows.

1 is an exploded perspective view showing a conventional heated cigarette, as shown in the configuration is a mouthpiece part 110 with a heater, a control unit 120 with a power supply 121 and a control circuit (not shown) And the mouthpiece part 110 and the controller 120 are electrically coupled by the contact pins 112 and the sockets 122, respectively.

Cigarette having the above configuration is a one-piece unit with a built-in heater element, the first to heat the cigarette of the initial model is difficult to control the heat source to improve the problem of low quality of the flavor to control the heat source constantly It was an electrically heated model. However, there is a problem that such a heated cigarette is not popular because the manufacturing cost is high because the heater element is one-time.

In order to solve the above problems, the disposable heating cigarette heater element was separated and changed into an electric heater that can be used semi-permanently. Meanwhile, the study on the improvement of the heater element for the electric heater and the improvement of the structure of the heating cigarette The research has been largely divided into studies.

US Patent Application No. 93-118665, currently the most popular model, introduces a smoking system comprising a heated cigarette and an electric heater capable of delivering improved aerosol and taste from the cigarette.

FIG. 2A is a partially cutaway perspective view illustrating a conventional heated tobacco smoking system, and FIG. 2B is an enlarged perspective view of a heater in the configuration of FIG. 2A, and as shown in the related art, the conventional smoking system generates tobacco response. It is possible to supply power to the electric heater (220) and the electric heater (220) having a built-in heated cigarette (210) and an electric heater element for heating when the cigarette (210) is inserted. The power supply unit 230 is configured.

Looking in more detail of the electric heater 220, the heater unit 221 for heating while wrapping the outside of the cigarette 210 inserted through the insertion hole 222 of the front is provided, whether smokers smoke An optical sensor 223, a circuit element 224, and an indicator 225 are provided. In addition, the power supply unit 230 has a built-in rechargeable battery 231 that can store electricity. It is necessary to create an environment with a temperature higher than the proper temperature at which cigarettes can express taste, which requires a large-capacity rechargeable battery to supply power. Components are installed to prevent waste.

However, the electric heater 220 as described above obtains the fragrance expression by heating the outside of the cigarette inserted in the eight heater blades 221a formed in a cylindrical shape in the heater unit 221. As a tube in tube method, this method inevitably has a problem in that thermal efficiency is low because heat is emitted to the outside of the heater unit 221.

In addition, the components installed for the convenience of the user act as a factor that increases the manufacturing cost of the product not only increases the burden of the purchase cost, but also the size is unnecessarily large and the weight is heavy, so between the fingers usually It was inconvenient to use because the previous habit of using it was not used as it is.

The present applicant has solved the above problems and proposed an electric heater of an electric heated cigarette system having a stable shape and structure which is not easily deformed even when pressure is applied when inserted into the heat source unit. 0636287].

Electric heater 1 of the Republic of Korea Patent No. 10-0636287 is a cylindrical body 10, the heating tobacco 2 is inserted into the interior as shown in Figure 3, the power provided on one side of the closing surface of the body 10 It consists of a connection port 20, and the heating portion 30 is installed in the body 10 in the length of the needle (Probe) along the longitudinal direction. The needle-shaped heating part 30 is naturally located inside the filling layer of the cigarette 2 when the heated cigarette 2 is inserted into the body 10, and the heating part 30 which is supplied with power later is heated. The distillation of tobacco fillings is thus distilled, whereby the user inhales the material formed by the distillation through the tobacco filter. Therefore, no combustion compound or heat deformation material, which is a tobacco product by conventional combustion, is produced, and only a distilled extract in a lower temperature range, which is known to contain a substance which is relatively harmful to the human body, can be inhaled. Unlike this, there is an advantage of inhaling a good flavor from which paper odor and odor are removed by carbonization of the cigar paper surrounding the filling.

The electric heating cigarette using the electric heater 1 described above is easily deformed when the heating part 30 is slightly pressurized due to a special structure in which the heating part 30 is inserted into the cigarette filling. Therefore, there has been a demand for the development of an electric heating cigarette having a stable shape and structure that is convenient to carry and does not deform even when pressure is applied to the heat source.

In addition, the electrically heated cigarette is a method of inhaling aerosols generated by heating of the heating element, not by pyrolysis, and thus, the structure of the filter according to the structure of the heating element, the location of the cigarette and the heating element, the heating temperature, the heating method, and the like, and the addition of the flavoring agent. Conditions such as anticorrosion, cigarette paper and foliar combination should be designed to be suitable for electric heaters.

Since the structure and characteristics of the conventional electrically heated cigarettes are very complicated and diverse in the manufacturing process, it is impossible to manufacture a general conventional cigarette facility, which is a factor that increases the unit cost of the electrically heated cigarette. Therefore, it is an urgent time to develop an electric heated cigarette that can be manufactured using a cigarette facility for producing a cigarette by general combustion.

The present invention is to solve the above problems, the needle-like heating element is easily inserted, in order to improve the taste, aroma, flavor of the electric heating cigarette using the needle-like heating element, the structure of the filter, cigarette paper, leaf combination And a method for adding a flavoring agent.

In addition, the present invention has another object to propose an electric heated cigarette that can be produced using a general cigarette facility.

In order to achieve the above object, the present invention, in the electrically heated cigarette, the cigarette 420 is filled with a mixture 421 including the filter 410 and tobacco leaf, moisturizer, flavoring agent and tobacco extract. It is composed of, the aluminum foil 422b and the paper 422a is bonded to the cigarette paper 422 is wrapped around the cigarette portion 420, characterized in that it is provided with an encapsulated flavourant 431.

Hereinafter, the features of the present invention will be described in detail with reference to the accompanying drawings, and for the sake of clarity, the same components are denoted by the same reference numerals throughout the specification, and the size and shape of each component are provided for ease of recognition. It may be exaggerated.

Shape of Electric Heating Cigarette

4 is a partial perspective view of the electric heating cigarette of the present invention, and comprises a filter 410 and a cigarette part 420 filled with a mixture including leaf tobacco, humectant, flavoring agent and tobacco extract, wherein the cigarette part ( When the needle-shaped heating element is inserted into 420 and heated, it generates aerosol.

It is preferable that the electric heating cigarette of the present invention maintain the same size and shape as a conventional cigarette. The cigarette diameter L3 is preferably in the range of 5.4-8.5 mm, preferably 7.0-7.8 mm, in order for the user to be adapted to the habit habitual form like a conventional cigarette. The length of the cigarette is preferably 45-100 mm in total length (L1 + L2), and most preferably 60-82 mm.

The filter length L1 is preferably 15-35 mm, most preferably 20-30 mm. The length L2 of the cigarette part in which the leaf tobacco is filled is 20-84 mm, preferably 20-60 mm, most preferably 50-60 mm.

The structure of the cigarette consists of a filter 410 and a cigarette part 420, wherein the electric heating cigarette having the size and shape as described above is continuously sealed in the cigarette machine by heat-sealing the tobacco fillings along the longitudinal joints. Since it can be manufactured by passing through the filter plug bonded to the continuous drum, there is an advantage that can be used as a conventional equipment such as cigarettes, packaging machines.

At this time, the filter 410 is a donut type 411 through the long axis of the cigarette, it is preferable that the through surface has a concave-convex shape (411).

Cigarettes and added fragrance substances are evaporated by heat generated from a needle-like heating element inserted through the punctured central portion 411 of the filter 410 to generate a vaporous substance, and a large amount of aerosol including the vaporous substances. This can be easily delivered to the smoker.

The characteristics of the penetrated filter 410 facilitate the inhalation of vaporous material even with low resistance when smoking and adjust the amount of delivery medium for taste or aroma during smoking. In addition, when the aerosol passes through the filter, the vapor phase cools, condenses and discharges to the pressure drop at the hollow filter site. In addition, the donut-shaped through hole, the filter having a concave-convex shape facilitates insertion of the acicular heating element into the central portion of the cigarette portion 420.

When adjusting the amount of aerosol generated by the filter 410, select the appropriate porosity of the filter paper (not shown) surrounding the filter 410, and dilute to 10-80% by drilling a dilution hole in the tip paper 432. Can be.

The dilution port is adjusted according to the degree of generation of aerosols and the scent intensity by the constituents of the mixture. It is preferable to dilute 20-60%, most preferably 30-50%.

Filling mixtures for electric heated cigarettes

The cigarette unit 420 is filled with a mixture of leaf tobacco, moisturizer, flavoring agent and tobacco extract. Cigarette blending, flavoring, and moisturizing agents suitable for the heating system should have a cigarette blending system that can be selected as a favorable product from consumers.

Cigarettes should be constructed so that aerosols can be abundantly produced in flavorings or leaf tobacco of the filling mixture after inhalation of at least eight times. Glycerine or propylene glycol, which is an aerosol-generating material, is transformed into a vapor phase and passed through the filter 410 by the heat generated by the inserted heating element. The density of the mixture 421 filling the cigarette part 420 is It has a great influence on the amount of aerosol formation, duration, the degree of aerosol movement by suction force, and the insertion resistance of the needle heating element. In order to generate a desired aerosol and to move and reduce the insertion resistance of the acicular heating element, the filling density of the mixture 421 of the cigarette part 420 is preferably 0.2-0.3 g / cm ³ , more preferably 0.24-0.28 g more preferably / cm ³ .

Ingredients that make up tobacco taste are raw leaf tobacco, fragrances and ingredients. Among them, the main ingredient of taste is raw leaf tobacco.

Tobacco used for heating is manufactured in the form of cigarettes by cutting tobacco leaf mixed with various varieties and adding flavoring agent, moisturizer and other additives. At this time, the mixed leaf tobacco is composed of yellow species, burley species, orient species, platelets and expanded leaves is a general form of mixing, this type of foliar compounding depends on how the target taste and aroma of tobacco.

Leaf blending must specifically characterize the different varieties of grades in order to produce tobacco that meets the goals set. To understand the specific taste, aroma, and physicochemical characteristics of tobacco, and to mix properly. The quality of the manufactured cigarette is determined by the needs of smokers who feel the taste of the smoke when smoking. Therefore, the separation, identification and quantification of harmful components in tobacco components and other biochemical tests were actively conducted to determine alternative tobacco foliar composition, which is a less harmful tobacco. The varieties to be blended are yellow leaf and toast leaves, which are used as flavoring agents, and their characteristics are less irritating and odorous, and less fragrance than flavors, but they have a pleasant taste and become the main raw material of heated edible mixtures. Taste species include yellowish yellow species and orient species, and have a rich aroma and taste, and become a center for expressing taste of product quality. There are other emollients such as mesenchymal midrib and swelling kerosene, which harmonize with strong and irritating taste and increase swelling to improve the flow of air in the tube. Supplements include platelets and bulging veins. Lamellar leaf is a raw material manufactured by reconstructing leaf tobacco by-products, so it has the best conditions to be suitable for heating type. Preferred leaf combinations for the above-described electric heating cigarette of the present invention are summarized in Table 1.

(Table 1) Composition ratio of leaf composition of electric heating cigarette

A moisturizer is added to the leaf tobacco with foliar composition as described above. The moisturizer (aerosol precursor) softens the leaf tobacco tissues to suppress the breakage during drying, and if it is productized, it improves taste and reduces irritation by maintaining moisture. It keeps the quality level unchanged during storage.

It is known that when the moisture of the product tobacco is dried below 12%, the irritation increases, which greatly affects the taste of tobacco. Examples of the moisturizing agent include glycerol, propylene glycol, sorbitol, and the like. As the moisturizing agent having high thermal stability, there are glycerol, propylene glycol, and the like. Therefore, it is preferable to use glycerol at this stage because the primary fragrance process of leaf tobacco treatment is related to the high temperature heat treatment process, and the fragrance and solubility are good in the second fragrance process since it is made of vinegar and has high permeability to leaf tobacco tissue. Preference is given to using glycols.

As described above, the moisturizing agent that maintains the moisture of the product to determine taste and flavor, and determines the amount of aerosol, preferably has a weight ratio of 0.5-10 wt% based on the weight of the leaf tobacco. If the amount of the moisturizer is out of the above weight ratio, the taste and flavor may be damaged due to lack of moisture, or if an excessive amount is added, an unnecessarily large amount of aerosol may be generated to give taste and flavor as well as to the quench ticket. Can infringe.

Cigarette Paper for Electric Heating Cigarettes

The cigarette paper of the electric heating cigarette of the present invention is characterized in that the cigarette paper 422 to which the aluminum foil 422b and the paper 422a are bonded.

A general cigarette paper is composed of natural cellulose fiber, hard calcium carbonate salt and a coagulant. As raw materials, organic fibers mainly composed of flax and the like and minerals, which are fillers such as hard calcium carbonate, are used. Cigarette pulp fibers tend to prefer hemp fibers because of their taste, physical properties, and appearance quality, but they are also used in combination with wood due to the acquisition of raw materials and an increase in manufacturing costs. However, due to the development of grassland technology, in recent years, France (PDM), the United States (ECUSTA), etc., do not use mappulp and produce cigarette paper having good physical properties with only pure wood. Calcium carbonate is mainly used as a filler for cigarette paper, but a mixture of titanium dioxide is also used. The overall mixing rate is about 20-30 wt%, but nowadays low magnesium smoke papers use 30-40 wt% mixed magnesium oxide. Papers used in such cigarette papers have the effect of improving whiteness and opacity, improving porosity and gray matter, improving feel and printability, and reducing paper odor when smoking cigarettes.

However, unlike conventional cigarette papers, what is important in the cigarette paper of an electric heating cigarette is thermal stability and strength.

If a needle-like heating element is inserted and heated to a high temperature and smoking ends or is stopped arbitrarily, the heating element should be removed. At this time, an external physical force is inevitably applied to the cigarette. Then, when the strength of the cigarette paper drops due to the heat applied to the paper, the problem of the cigarette paper breaking due to these pressures occurs.

The cigarette paper 422 of the electric heating cigarette of the present invention can have a high thermal stability and strength by using a cigarette paper 422 to which the aluminum foil 422b and the paper 422a are bonded as shown in FIG. 5. do. Cigarette paper 422 should be a good restoreability and stability and slipperiness that the aluminum foil 422b and the paper 422a is uniformly bonded. Preferably, the cigarette paper 422 is preferably used in which a 30-70 μm-thick white paper 422a having a basis weight of 37-43 g / m ² is bonded to an aluminum foil 422b of 4-8 μm thick. .

In detail, the aluminum foil has a purity of 99.3% or more and a thickness of 7 ± 0.7 μm and a weight of 18.97 ± 1.89 g / m 2 are preferably used, and the basis weight of the paper bonded to the aluminum foil is 40 g / m 2 (permissible difference). 7%), the center value of the thickness is 50 ㎛, it is preferable to use a white paper prepared in the ash content of 11 wt% or less, wherein the whitening paper should not be detected fluorescent brightener.

It is of utmost importance that the tobacco manufacture be carried out without interruption of operation. Over the last few decades, we have been working on the development of high-speed cigarette paper with high-pore cigarette paper, with a focus on the tensile strength and field workability of the cigarette paper. Securing these properties depends on the proper combination of techniques such as fiber type processing, pulping of pulp, uniformity of fusion, filler content, and the like.

Cigarettes enclosing cigarettes shall be double rolls of aluminum. It must be of sufficient weight and thickness and have sufficient tensile strength for the mechanical process. It is influenced by the quality of the white paper and good adhesion to the aluminum foil. Adhesion should be preheated and embossed roll at 78 ° C for 1 to 8 hours and paper and aluminum foil on the cut surface after passing. When similarly torn in the perpendicular direction of the cut plane, the visible area of the foil should adhere well to less than 5% of the total tear area. All bonds of cigarette paper are liquid starch adhesives. The width of the cigarette paper to be bonded is best about 2 mm, and a high temperature electric iron is operated to dry the cigarette flowing at high speed after the adhesive is applied.

Table 2 summarizes the physical characteristics of the cigarette paper to which the aluminum foil and paper are bonded.

Flavors for Electric Heated Cigarettes

The flavoring agent 431 of the present invention is characterized by being encapsulated and composed of a capsule material surrounding the flavoring material and the flavoring material, the capsule is destroyed by the heating of the inserted needle heating element, and the flavoring agent is delivered to the evaporated smoker.

The fragrance work aims to add flavors suitable for blended cigarettes of different varieties and grades to enhance taste, to provide flavor and moisture, to increase the amount of smoke and to enhance the inherent aroma of tobacco taste.

The general fragrance stage can be divided into the primary fragrance of low volatility fragrance and the secondary fragrance process of volatile fragrance. Among them, the primary fragrance mixes the fragrance liquid with water and directs it to the spray nozzle, and the secondary fragrance uses an organic solvent (ethanol), so that the vapor pressure is increased inside the fragrance. At this time, the mechanism penetrating into the leaf tobacco proceeds by the adsorption and condensation in the gaseous state. If the penetration rate is slow in the process, the adhesion and dispersion are good, and the adsorption adsorption is uniformly distributed by vaporization adsorption. If the penetration rate is high, it is difficult to attach and disperse, resulting in inconsistent fragrance, which causes spots. The ethanol infiltration time in the secondary tendency differs depending on the composition ratio and water content. If the fragrance is carried out in a short time, the time for ethanol to move into the leaf tobacco tissue is not enough, and the actual ethanol stops at a high concentration. Therefore, it is difficult to expect the uniform flavor of the fragrance suitable for the level of a heated tobacco by atomizing and adding the conventional flavor liquid.

When the flavor is added by the conventional method as described above, a considerable amount of the volatile or nonvolatile taste component of many flavors is evaporated and lost during the tobacco manufacturing process or storage. Therefore, it may not be possible to deliver a uniform flavor to consumers every smoking cycle.

The encapsulated flavourant 431 of the present invention utilizes a variety of materials in the capsule packaging of the flavourant to prevent the loss of flavor or divergence concentrated in the initial smoking cycle.

Encapsulation is made by forming a continuous thin film on the outside of the subject material. The encapsulated flavourant 431 is composed of a macrocapsule having a diameter of 5000 µm or more, a microcapsule having 0.2-5000 µm or a nanocapsule of 0.2 µm or less, or a combination thereof. The nanocapsules of 0.2 μm or less have a size of 0.2-0.01 μm in detail. It is divided into core material (fragrance material to enhance the taste of cigarette) and wall material (outer membrane material of capsule) .The general manufacturing process is the first capsule process through the first emulsification process and the second after the second emulsification process. After the capsule film forming process step, it may be prepared by the capsule film curing process. Gelatin and water are mixed at 40-60 ° C., and the acidity is adjusted through the first and second emulsification steps, followed by the capsule film formation process. Then, the gelation proceeds at 5-15 ° C. to form an outer membrane and the encapsulation process is completed.

The encapsulated flavoring agent 431 is composed of a capsule material surrounding the flavoring material and the flavoring material as described above, the flavoring material comprises a flavor enhancer, an emollient and a natural extract, the capsule film material is starch, guar Preference is given to gums, agar, chinosan, gelatin, factin or green algae, or mixtures thereof.

At this time, the fragrance enhancer ethylacetate, ethyl propionate, ethyl aprotonate, acetanonil, benzaldehyde, dimethylpyrazine, dimethylpyrazine, damascone or damacenone ), Or a mixture thereof, wherein the emollient is citric acid, maleic acid or glycol, or mixtures thereof, and the natural extract may be tobacco extract, fruit, herb, coffee or It is preferred that it is a citral extract, or a mixture thereof.

The encapsulated flavourant 431 should not form toxic and irritant components upon heating or combustion after manufacture, and preferably releases fragrance at 60-100 ° C., and has sufficient mechanical strength so as not to break upon addition to a cigarette. It should have a stability that does not break even after 12 months or more. Color should also not affect the final product.

As shown in FIG. 6, the encapsulated flavourant 431 may be provided between the filter 410 and the cigarette part 420 to form the flavourant filter part 430. At this time, the length of the flavourant filter portion 430 may be 5-15 mm, preferably 5-10 mm, and most preferably 5-7 mm.

The encapsulated flavourant 431 may be provided inside the mixture 421 filled in the cigarette part 420, as shown in FIG. 7, wherein the encapsulated flavourant 431 is a cigarette paper 422. ) It may be provided on the inner base wall (FIG. 8) or the inner surface of the aluminum foil 422a.

The capsule-type flavoring agent 431 provided in the flavor filter part 430, the cigarette paper 422, or the mixture 421 is heated when the needle heating element inserted in the cigarette part 420 is heated to dissipate heat. The flavor capsules are then destroyed and evaporated so that the flavor components are delivered to the user along with the aerosol carrier.

In addition, in the structure of the electric heating cigarette of the present invention, at least one row of through holes 440 may be formed at an optional position of the filter 410 as shown in FIGS. 6 to 8. The through hole 440 serves to supply the outside air to the inside of the cigarette to improve the resistance to inhalation and to facilitate the delivery of aerosols.

The encapsulated flavourant 421 is protected with fragrances and other functional substances, the release rate is controlled from the inside, and oxidation and decomposition of the substance due to air, light, etc. are prevented. It also has several functions to separate fragrance components that can cause interaction between additives, to extend shelf life, and to control the color, texture and fragrance of materials.

The electric heating cigarette of the present invention has the advantage of effectively delivering a relatively harmless tobacco distillate to smokers because the added flavor or leaf tobacco is not modified by pyrolysis or synthesis, and can be free from limitations of smoking rights, health and the environment It has the effect of satisfying the new preference of the individual who cares about it.

In addition, since the size, shape and manufacturing method is similar to the general cigarette manufacturing method, there is an advantage that can be produced by the electric heating cigarette using a conventional manufacturing equipment, using a foil paper using aluminum foil to improve thermal stability and strength By optimizing foliar blending and mixtures, and by adding encapsulated flavours to the cigarette or filter area, the tobacco taste or aroma delivered to the smoker is uniformly and abundantly delivered from the first inhalation to the last, increasing smoking satisfaction. Has the advantage of.
