Description

Disposable double-channel cigarette

Technical Field

The utility model belongs to a cigarette field, in particular to disposable binary channels cigarette.

Background

After long-term exploration and summary, the tobacco product serving as a favorite commodity for daily consumption is found to have the following three characteristics preferentially if the tobacco product is successful in the market and can meet the core consumption experience at the same time: the product can be sucked mouth by mouth, consumed at one time and safely sucked. Wherein the mouth-to-mouth suction is adapted to the breathing mode of the person; the disposable consumption is mainly because the daily consumption of the cigarettes is convenient; the safety of the food is the minimum requirement of the food. Products which do not properly satisfy the three characteristics are ultimately difficult to achieve in the market.

In the traditional field, the traditional tobacco products are combustion-type tobacco products which utilize chemical energy provided by the combustion of tobacco to generate physical and chemical reactions and release various chemical substances for smokers to eat. Traditional tobacco products can realize suction one by one in a burning and sucking mode, and the remaining part can be discarded after the smoking is finished, so that a disposable consumption mode is realized, and the tobacco products can be accepted by consumers all the time due to the fact that the tobacco products can be well fitted with a daily consumption experience mode and have a history of hundreds of years.

With the progress of scientific technology, most research results suggest that thousands of substances are released by high-temperature thermal cracking reaction of more than 800 ℃ in the traditional combustion and absorption mode tobacco products in the combustion process of tobacco, and the substances are the main causes of most people's diseases and harm to human health. Although filter sticks with better and better filtering efficiency and ventilation dilution effect are continuously applied to cigarettes, the traditional tobacco products are more and more difficult to meet the minimum requirements of food in the present day that the food safety concept is continuously improved, and particularly the defect of smoking safety is more and more difficult to obtain the recognition of consumers.

In recent years, with the continuous enhancement of health appeal, the requirement of cigarette smoking safety is raised to unprecedented height, and with the rapid technological innovation momentum and the guidance and regulation and control strength of the tobacco-related laws and regulations, the research of novel tobacco products presents a situation of all flowers, and various novel products are developed endlessly, mainly comprising the varieties of smoking tobacco products in oral cavity or nasal cavity, electronic cigarettes, heating non-combustion tobacco products (also called low-temperature cigarettes or HNB cigarettes) and the like. These new tobacco products share three common features: the harm to smokers is small, and because the smokers do not participate in combustion during smoking, the novel tobacco products are considered to generate less harmful substances; secondly, the harm to the environment is small, the novel tobacco product does not generate second-hand smoke, and the pollution to the environment and the harm to other people caused by the traditional tobacco product are reduced; and the novel tobacco product contains nicotine, and can meet the physiological requirements of smokers to a certain extent.

However, there is a significant proportion of consumers, particularly those with a long smoking history, who are reluctant to select any new type of tobacco product to stay in the smoking mode for a long period of time, either because of the need for a strong smoking satisfaction and a high nicotine tolerance, or because of being used to consume them at one time, or because of the use of the puff-by-puff habit, among other reasons. The specific reasons include that the electronic heating non-combustion tobacco product is not disposable consumption, and is troublesome to carry, repeatedly charge and use; carbon-heated non-combustible tobacco products and physical and chemical reaction heating type tobacco products are accompanied by bad smell and reduced smoking quality in the smoking process.

Next, a systematic analysis was performed for different categories of heat-not-burn tobacco products:

the tobacco products which are not heated and not combusted can be divided into 'electric heating type tobacco products', 'fuel heating type tobacco products' and 'physical and chemical reaction heating type tobacco products' according to different heating sources. The electric heating type tobacco product consists of two parts, namely a special cigarette and an electric heater, is a mature mainstream product in a heating non-combustion tobacco product, wherein the most important representatives are IQOS of Femo international company, Glo of Enmei tobacco company and Pgloom of Japanese tobacco. Fuel-heated tobacco products use combustible solids, liquids or gases as a heat source, among which solid (carbonaceous) fuel type commercial products are proposed, such as "Premier", "Eclipse" by the company reynolds and "Revo" newly proposed in 2015. However, the fuel heating type tobacco products which can burn liquid or gas are only patented, and no products are yet on the market. The physical and chemical reaction heating type tobacco products mainly heat the tobacco core materials by certain physical and chemical methods, for example, a mode of generating heat by crystal crystallization belonging to physical reaction or a mode of generating heat by oxidation reaction of metallic iron, aluminum and lead-in oxidation belonging to chemical reaction, and the current physical and chemical reaction heating type tobacco products only have patents and have no products on the market. The above-mentioned tobacco products which are not burned by heating have the following technical defects because of the influence of the process, design and structure:

firstly, the electric heating type tobacco product manufactured by the prior art is composed of a special cigarette and an electric heater. Although a better solution is obtained to the two problems of mouth-to-mouth suction and safety of smoking, as described in the chinese patent "heated aerosol generating device and method for generating aerosol with consistent characteristics" patent application No. CN2017108122320, other serious problems are introduced: firstly, the special cigarette and the electric heater 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 used for one-time consumption; thirdly, the most important is that the battery has a great potential safety hazard, and the true case that the battery matched with the electric heating tobacco product explodes to cause the user to suffer serious personal injury appears and is reported; fourth, because the discarded batteries need special treatment, not only is extra disposal cost generated, but also the batteries which are not properly disposed of cause serious pollution to the environment, resulting in an increase in environmental protection pressure. In summary, all new tobacco products requiring batteries have serious technical defects and should be discarded or eliminated.

Second, unlike the electrical heating type tobacco products, the fuel heating type tobacco products manufactured by the prior art have great basic conditions in terms of disposable consumption and use, but have significant technical defects in terms of smoking safety and puff-by-puff smoking. First, when the fuel and the tobacco are in a serial positional relationship, a through air flow channel is formed, and thus, undesirable substances generated by combustion of the fuel are directly introduced into the oral cavity of a smoker due to the smoking action of the smoker, for example, the contents described in the invention of chinese patent "Revo" which is a product of Reynolds tobacco corporation, patent application No. CN2017212244171 which is a disposable heating non-combustible cigarette, patent application No. CN2015107601314 which is a method for producing a carbon-heating low-temperature heating cigarette, and patent application No. CN2013101448434 which is a dry distillation type cigarette.

When the fuel and the tobacco are not connected in series, for example, the patent application No. CN201520038334.8 of a carbon heating non-combustion tobacco smoking device, the patent application No. CN201810414111.5 of an isolated self-overflowing carbon baking type low-temperature cigarette and a preparation method thereof, the patent application No. CN2013105629941 of a heating type low-temperature cigarette and a preparation method thereof, and the like describe the contents. 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, more incomplete combustion products are generated, and the problems of easy flameout, low heating efficiency and the like are solved; secondly, the ignited fuel is continuously combusted automatically, and the actual situation that the heat demand peak value is continuously changed when the ignited fuel is sucked one by one cannot be fitted, so that the tobacco heating effect is poor, the smoking taste and quality are poor, and the fuel waste is obvious. In view of this problem, patent application No. CN201810982289X, which is a non-combustible heating and 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 supply heat to the outside in a manner of complete combustion as much as possible, but the invention still has significant technical defects: first, because components such as a spring-driven fan and heat transfer elements are expensive, the invention is intended for repeated use rather than for single use. Secondly, the tobacco containing cavity for placing the tobacco substances is only provided with one end communicated with the outside air, so that the structural design can not lead the consumers to carry out the suction action and suck the smoke smoothly by means of the smoke flowing. Finally, and above all, the invention presents an uncontrollable and lasting character to the action of the fuel to provide the air flow, with a significant waste of fuel: the invention can not provide air flow according to the rhythm and the mode of the mouth-to-mouth suction in real time, so that the peak value of heat provided by the fuel combustion can not respond in real time. All the above problems are reduced, even the consumption experience of the consumer is deteriorated, and the problems should be replaced by better technical solutions.

Third, the physical and chemical reaction heating type tobacco products manufactured by the prior art mainly heat the tobacco core material by a certain physical and chemical method, for example, the crystal crystallization belonging to the physical reaction generates heat, or the metallic iron, aluminum and oxidation reaction belonging to the chemical reaction generates heat. Due to the relationship of the design principle, the method has the following significant technical defects: first, no matter physical or chemical reaction, the reaction may be initiated by high temperature or collision and drop during transportation, or even the reaction may explode. Secondly, the chemical reaction of the physical and chemical reaction heating type tobacco products also has the safety problem that the exhaust gas can directly enter the oral cavity of the smoker due to the smoking action of the smoker. Thirdly, also its physicochemical reactions, once initiated, continue to occur until the end of the reaction, and it is not possible to provide a variation in the heat peak in order to match the rhythm and the manner of the puff-by-puff.

Fourthly, with the traditional burning and sucking type, the demand of consuming the traditional tobacco products still exists. One of the reasons that most consumers do not select novel tobacco products is the use mode of the novel tobacco products, namely the mode of heating without combustion, the mode of tobacco tar atomization or the mode of chewing and sucking, and the effective components, namely the quantity and the types, of the effective components are difficult to reach the mixture of more than 4000 types brought by Maillard reaction through high-temperature thermal cracking at more than 800 ℃ in a combustion and suction mode of the traditional tobacco products. This leads to difficulties in completely replacing traditional tobacco products, both in terms of physiological satisfaction and in terms of smoking experience and quality. In addition, the same consumer may switch to smoking conventional tobacco products, or to smoking non-combustible tobacco products, at different stages or occasions. For example, in a crowded environment or during a season when the climate is dry, the consumer may tend to smoke and heat non-combustible smoking articles; in private settings or in climatically humid seasons, the consumer may be inclined to smoke conventional tobacco products. If a solution is sought under the prior art, the consumer can only purchase two products of the traditional tobacco product and the novel tobacco product for consumption at the same time, and the consumption cost of the consumer is greatly increased.

At present, many countries or regions which permit selling traditional tobacco products are limited to selling heating non-combustion cigarettes due to various reasons such as policies. If a cigarette can be selected between a conventional smoking mode and a non-heating mode, the policy-type constraints imposed on the product may be substantially reduced, theoretically reducing the difficulty of entering the country or region.

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

3) Electronic cigarettes, IQOS, a product of femo international, were used as a control group 2 for consumption in an electronic heating non-burning mode.

4) Series HNB cigarettes consumed in a carbon heating non-combustion mode, namely a product 'Revo' of Reynolds tobacco company, are adopted as a control group 3.

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

TABLE 1 comparison of Flexible consumption patterns

Experimental groups	Conventional fuel and suction mode requirements	Heating non-combustion mode requirement
			Example 1	Can satisfy	Can satisfy
Example 2	Can satisfy	Can satisfy
			Example 3	Can satisfy	Can satisfy
Control group 1	Can satisfy	Cannot satisfy
			Control group 2	Cannot satisfy	Can satisfy
Control group 3	Cannot satisfy	Can satisfy

And (4) conclusion: the control group 1, the control group 2 and the control group 3 can only adapt to or meet the consumption requirements in a single mode, so that the consumption cost is greatly increased under the background of diversified requirements, the market competitiveness is weak, and the products adopting new technologies are likely to replace the products. The utility model discloses a cigarette props up and can adapt to in a flexible way and satisfy the consumption demand of different modes, therefore has wide application prospect.

Example 5

The application comprises the following steps: flue gas index detection and comparison test

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

Table 2 flue gas index detection comparison test result units: mg)

And (4) conclusion: in the conventional smoking 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 results of the smoke index measurements in examples 1, 2 and 3 were entirely close to those in control group 2. The harmful indexes are obviously superior to those of the control group 3, and especially the indexes of the harmful substance carbon monoxide CO are far lower than those of the control group 3. Therefore, the nicotine content in the cigarette smoke of the utility model is basically unchanged, the harmful gas content is reduced, and the application prospect is wide.

Example 6

The application comprises the following steps: sensory evaluation comparison test

1) The disposable double-channel cigarettes prepared in examples 1, 2 and 3 were used as experimental groups.

The above example samples and the control group samples were used for sensory evaluation comparison tests. The results are given in Table 3 below.

TABLE 3 sensory evaluation comparison test results

And (4) conclusion: on the basis that the embodiment 1, the embodiment 2 and the embodiment 3 can flexibly adapt to and meet consumption requirements of different modes, under the condition that the modes are the same, the sensory quality evaluation is smaller in stimulation than that of the control group 1, and is more comfortable than the aftertaste of the control group 2 and the control group 3, so that the sensory quality is obviously improved, and the application prospect is wide.

Example 7

The application comprises the following steps: testing of modes of matched puff-by-puff

1) The disposable dual-channel cigarettes prepared in examples 1, 2 and 3 were used as experimental groups 1-3.

5) The control group 4 was prepared by preparing a smoking device and filling tobacco shreds by the method described in chinese patent CN102018000982289, a smoking device for tobacco which is not combustible by heating and is based on a mechanical energy storage type air extraction assembly.

The temperature of the tobacco was measured and recorded during the smoking process for different periods of time, for characterization and comparison of the peak change in caloric value, for the example sample and the control sample described above. The results are shown in FIGS. 17 to 23.

And (4) conclusion: from the analysis in above-mentioned fig. 17 ~ 23, the utility model discloses an embodiment 1, embodiment 2, embodiment 3 can promote the temperature of tobacco with the mode of matching suction one by one, obtain better consumption experience, and the effect is similar with contrast group 1, contrast group 2 and contrast group 3. The control group 4 continuously raises the tobacco temperature in an uncontrolled state, the waste of fuel substances is very obvious, and meanwhile, the control group cannot be matched with a mouth-by-mouth smoking mode, the consumption experience is poor, and the application prospect is dull.
