Description

Disposable double-channel cigarette and preparation method thereof

Technical Field

The invention belongs to the field of cigarettes, and particularly relates to a disposable double-channel cigarette and a preparation method thereof.

Background

Through long-term searching and summarizing, the tobacco product is used as a hobby commodity for daily consumption, and if the tobacco product is successful in the market, the core consumption experience can be met, and the tobacco product must have the following three characteristics: sucking mouth by mouth, disposable consumption and safe sucking. Wherein, the mouth-by-mouth suction is adaptive to the breathing mode of the person; the disposable consumption is mainly due to the fact that the daily consumption of cigarettes is mainly convenient; the safety of the food is the minimum requirement of the food. Products that do not properly meet the three characteristics are ultimately difficult to achieve in the marketplace.

In the traditional field, traditional tobacco products are combustion-type tobacco products which utilize chemical energy provided by tobacco combustion to perform physical and chemical reactions and release various chemical substances for smokers to inhale. Traditional tobacco products can be sucked in a combustion-sucking mode, and the rest parts can be discarded after the sucking is finished, so that a disposable consumption mode is realized, and the tobacco products can be well attached to a daily consumption experience mode and are accepted by consumers all the time, and have a history of hundreds of years.

With the progress of scientific technology, most research results consider that in the tobacco combustion process, the traditional combustion-suction mode tobacco products release thousands of substances through the high-temperature pyrolysis reaction above 800 ℃ is a main cause of the most people's problems and the harm to the human health. While filter rods with increasingly better filtration efficiency and ventilation dilution are increasingly being used in cigarettes, today with increasingly advanced food safety concepts, traditional tobacco products are increasingly difficult to meet as minimum requirements for food, especially for smoking safety.

In recent years, along with the continuous enhancement of health appeal of people, the smoking safety requirement of cigarettes is improved to an unprecedented height, and the rapid technological innovation potential is added, the guiding and regulating force of the laws and regulations related to cigarettes are enhanced, the research of novel tobacco products presents a state of full bloom, and various novel products mainly comprise varieties such as smoking tobacco products in the oral cavity or the nasal cavity, electronic cigarettes, heating non-burning tobacco products (also called low-temperature cigarettes or HNB cigarettes) and the like. These new tobacco products share three common features: 1. the harm to the smoker is small, and the smoker does not participate in combustion of the novel tobacco product when inhaling, so the generated harmful substances are considered to be less; 2. the harm to the environment is small, no second-hand smoke is generated in the novel tobacco product, and the pollution of the traditional tobacco product to the environment and the harm of other people are reduced; 3. the novel tobacco product has certain characteristics of the traditional tobacco product, contains nicotine, and can meet the physiological needs of smokers to a certain extent.

However, there are also a significant proportion of consumers, particularly those who have a long history of smoking, who are reluctant to select any new tobacco product for a long period of time in the traditional tobacco product of the burn mode, either because of the need for a strong puff satisfaction and a high nicotine tolerance, or because of the habit of disposable consumption, or because of various reasons such as mouth-by-mouth smoking habits. The specific reasons include that the electronic heating non-combustible tobacco products are not disposable, and are troublesome to carry, repeatedly charge and use; the carbon heating does not burn the tobacco product and the physicochemical reaction heats the tobacco product, and the smoking quality is reduced along with bad breath in the smoking process.

Next, for different categories of heated non-combustible tobacco products, a system analysis was performed:

the heating non-combustible tobacco products can be subdivided into "electrically heated tobacco products", "fuel heated tobacco products" and "physicochemical reaction heated tobacco products", depending on the heating source. The electric heating type tobacco product consists of a special cigarette and an electric heater, is a mature main stream product in the heating non-combustion tobacco product, and the most important representatives are IQOS of Feimo International company, glo of Yimei tobacco company and Plaom of Nicotiana japonica. Fuel-heated tobacco products use combustible solids, liquids or gases as a heat source, with solid (carbonaceous) fuel being commercially available products such as "Premier", "Eclipse" from the reynolds tobacco company and "Revo" newly introduced in 2015. However, liquid or gas combustible fuel-heated tobacco products are only patented and no products are yet marketed. The physical and chemical reaction heating type tobacco products mainly heat the tobacco core material through a certain physical and chemical method, for example, the physical reaction crystal crystallization generates heat, or the chemical reaction metal iron, aluminum and oxidation reaction generate heat, and at present, the physical and chemical reaction heating type tobacco products have only patents and no products are marketed yet. The heating of the non-combustible tobacco products has the following technical defects due to the influence of the process, the design and the structure:

1. the electric heating tobacco product made by the prior art consists of a special cigarette and an electric heater. Although a better solution is obtained in terms of two problems of mouth-by-mouth suction and suction safety, such as the content described in the patent application CN2017108122320 of the chinese patent, "heating aerosol generating device and method for generating aerosol with consistent characteristics", other serious problems are introduced: firstly, special cigarettes and electric heaters are required to be carried at the same time, so that the carrying is very inconvenient; secondly, the battery in the electric heater needs to be charged repeatedly, so that the electric heater is inconvenient to use and cannot be consumed for one time; thirdly, the most important is that the battery has great potential safety hazard, the battery matched with the electric heating type tobacco product explodes, and the real case that the user suffers serious personal injury appears already and is reported; fourth, since the scrapped battery requires special treatment, not only is additional disposal cost generated, but also the battery which is not properly disposed of will cause serious pollution to the environment, resulting in an increase in environmental protection pressure. In summary, all the novel tobacco products which need to be matched with the battery have serious technical defects and should be abandoned or eliminated.

2. Unlike electrically heated tobacco products, fuel-heated tobacco products produced in the prior art have significant technical drawbacks in terms of safety for consumption and mouth-by-mouth smoking, although they have very good basic conditions in terms of disposable consumer use. Firstly, when the fuel and the tobacco are in a serial position relationship, a through air flow channel is formed, so that bad substances generated by burning the fuel can directly enter the oral cavity of a smoker due to the sucking action of the smoker, for example, the Revo product of Reynolds tobacco company, and the contents recorded in the inventions of Chinese patent application No. CN2017212244171 of one-time heating non-burning cigarettes, preparation method of carbon heating low-temperature heating cigarettes, patent application No. CN2015107601314 of one-time heating low-temperature heating cigarettes, dry distillation type cigarettes, patent application No. CN2013101448434 and the like.

When the fuel and the tobacco are in a non-series positional relationship, for example, the contents of the inventions of patent application No. CN201520038334.8 of a carbon heating non-combustion tobacco smoking device, patent application No. CN201810414111.5 of an isolated self-overflow type carbon baking type low-temperature cigarette and a preparation method thereof, and patent application No. CN2013105629941 of a heating type low-temperature cigarette and a preparation method thereof are recorded. The technical defects are that the first fuel and the second fuel are combusted in a smoldering mode, the heat value is low, the effect is poor, and more incomplete combustion products are generated, such as easy flameout, low heating efficiency and the like; and secondly, the fuel is automatically and continuously combusted after being ignited, the actual condition that the peak value of the heat demand is continuously changed when the mouth-by-mouth suction can not be attached, the tobacco heating effect is poor, the taste and quality of the suction are poor, and the fuel waste is obvious. To solve this problem, patent application CN201810982289X, a heating non-combustion tobacco smoking device based on a mechanical energy-storage type air extraction assembly, discloses a solution for promoting air flow by using a spring-driven fan, in order to make the fuel supply heat outwards in a manner of complete combustion as much as possible, but the invention still has significant technical drawbacks: first, because of the high cost of components such as the spring driven fan and the heat transfer element, the invention is used for multiple repeated uses rather than for disposable use. Secondly, the tobacco accommodating cavity for accommodating tobacco substances has only one end communicated with the outside air, so that the structural design cannot enable a consumer to smoothly perform suction action and suck smoke by means of smoke flow. Finally, and most importantly, the invention presents an uncontrollable persistence characteristic to the action of providing air flow to the fuel, with significant wastage of fuel: because the invention can not provide air flow in real time according to the rhythm and the mode of the mouth-by-mouth suction, the peak value of heat provided by fuel combustion can not respond in real time, and colloquially, the technical scheme of the invention can lead to the fact that once a cigarette is ignited, the cigarette can be burnt all the time like a vehicle without brake without stopping, and the rhythm of a consumer is completely not ignored until the fuel of the cigarette is exhausted and the use value is lost. The problems are reduced and even the consumer experience is deteriorated, and the problems are replaced by better technical schemes.

3. The tobacco products are mainly manufactured by heating the tobacco core material through a certain physical and chemical method, such as a crystal crystallization heat generation mode belonging to physical reaction or a metal iron, aluminum and oxidation reaction heat generation mode belonging to chemical reaction. Due to the relation of the design principle, the method has obvious technical defects: first, either physical or chemical reactions may be caused by collisions or falls during transportation at high temperatures, or even by explosions. Secondly, the physical and chemical reactions heat the chemical reactions of the tobacco product, there is also the safety problem that the exhaust gas may directly enter the mouth of the smoker due to the sucking action of the smoker. Third, as such, the physicochemical reaction, once initiated, continues until the reaction is completed, and it is not possible to provide a peak change in heat in order to match the rhythm and manner of the port-by-port suction.

4. With traditional combustion, the need still exists to consume traditional tobacco products. One of the reasons why a great part of consumers do not select novel tobacco products is that the novel tobacco products are used in a way of heating, not burning, atomizing tobacco tar or chewing, and the effective components of the novel tobacco products, whether the number or the types, are difficult to achieve, in a burning and sucking mode, the traditional tobacco products are subjected to high-temperature pyrolysis at the temperature of more than 800 ℃ and the mixture of more than 4000 kinds brought by Maillard reaction is difficult to achieve. This results in new tobacco products that are difficult to completely replace traditional tobacco products, whether in terms of physiological satisfaction or in terms of the eating experience and quality. In addition, the same consumer may be diverted to smoking traditional tobacco products or to smoking and heating non-combustible tobacco products at different stages or occasions. For example, in a personnel intensive environment or in a season of dry climates, the consumer may prefer to smoke heat the non-combustible tobacco product; in private locations or climatically humid seasons, the consumer may tend to smoke traditional tobacco products. If a solution is sought under the prior art conditions, the consumer can only purchase two products of the traditional tobacco product and the novel tobacco product for consumption, and the consumption cost of the consumer is greatly increased.

5. At present, many countries or regions where the traditional tobacco products are permitted to be sold are limited to sell and heat the non-combustible cigarettes for various reasons such as policies. If a cigarette can be selected between a traditional smoking mode and a heating non-burning mode, the policy-type restriction factor to which the product is subject may be significantly reduced, theoretically reducing the difficulty of entering the country or region.

2) A conventional cigarette consumed in a burning mode was used as the control group 1.

3) An electronic cigarette for consumption in an electronic heating non-combustion mode, product IQOS of the feimo international company, was used as control group 2.

4) A tandem HNB cigarette, i.e. the product "Revo" from ranolase tobacco company, was used as control group 3 for consumption in a carbon heated non-burn mode.

The above example samples and control samples were used for a flexible consumption pattern comparison test. The results are shown in Table 1 below.

Table 1 flexible consumption pattern comparison test results

Group of experiments	Traditional combustion and suction mode requirements	Heating non-combustion mode demand
			Example 1	Can meet the following requirements	Can meet the following requirements
Example 2	Can meet the following requirements	Can meet the following requirements
			Example 3	Can meet the following requirements	Can meet the following requirements
Control group 1	Can meet the following requirements	Cannot meet
			Control group 2	Cannot meet	Can meet the following requirements
Control group 3	Cannot meet	Can meet the following requirements

Conclusion: the control group 1, the control group 2 and the control group 3 can only adapt to or meet the consumption requirement in a single mode, so that the consumption cost is greatly increased under the background of diversified requirements, the market competitiveness is weaker, and the control group is likely to be replaced by products adopting new technologies. The cigarette can flexibly adapt to and meet consumption requirements of different modes, and therefore has a wide application prospect.

Example 5

Application: flue gas index detection and comparison test

The samples of the embodiment and the control group are used for the smoke index detection comparison test. The results are shown in Table 2 below.

Table 2 smoke index detection comparison test result unit: mg)

Conclusion: in the conventional combustion and suction mode, the detection results of the smoke indexes of the embodiment 1, the embodiment 2 and the embodiment 3 are close to those of the control group 1, and the individual indexes are slightly better. In the heating non-combustion mode, the whole smoke index detection results of example 1, example 2 and example 3 are similar to those of the control group 2. The harmful index is obviously better than that of the control group 3, in particular to the harmful substance carbon monoxide CO index which is far lower than that of the control group 3. Therefore, the nicotine content in the cigarette smoke is basically unchanged, the content of harmful gases is reduced, and the cigarette smoke has wide application prospect.

Example 6

Application: sensory evaluation price ratio pair test

The samples of the above examples and the control group were used for the sensory evaluation pair test. The results are shown in Table 3 below.

TABLE 3 sensory evaluation of the price to test results

Conclusion: on the basis that the embodiment 1, the embodiment 2 and the embodiment 3 can flexibly adapt to and meet the consumption demands of different modes, the sensory quality evaluation is less in stimulation than the comparison group 1 under the condition of the same mode, and more comfortable than the comparison group 2 and the comparison group 3 in aftertaste, so that the sensory quality is obviously improved, and the application prospect is wide.

Example 7

Application: matched port by port aspiration mode test

1) Disposable two-channel cigarettes prepared in examples 1, 2 and 3 were used as experimental groups 1 to 3.

5) The method described in Chinese patent CN102018000982289 of heating non-burning tobacco smoking device based on mechanical energy storage type air extraction component is adopted to manufacture the smoking device and fill tobacco shreds, and then the comparison group 4 is manufactured.

During the smoking process, the temperatures of tobacco of the above example samples and control samples were measured and recorded for different time periods, for characterization and comparison of peak heat change. The results are shown in FIGS. 17 to 23.

Conclusion: from the analysis of fig. 17 to 23, it is shown that the embodiment 1, the embodiment 2 and the embodiment 3 of the present invention can raise the temperature of tobacco in a mode of matching the mouth-by-mouth suction, and obtain a better consumption experience, and the effect is similar to that of the control group 1, the control group 2 and the control group 3. The control group 4 continuously increases the tobacco temperature in an uncontrolled state, so that the fuel substance waste is quite obvious, meanwhile, the fuel substance waste cannot be matched with a mouth-by-mouth suction mode, the consumption experience is poor, and the application prospect is dark.

The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
