Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of heated cigarettes, and particularly relates to a center heated cigarette easy to pull out of a heating cigarette device and a testing method. BACKGROUND

[0002] Heated cigarettes are heated by an external heat source to heat tobacco substances, so that the aerosolization medium, flavor components and additional flavors in the tobacco substances are generated by heating to produce smoke similar to traditional cigarette combustion, so that consumers can get physiological satisfaction. Since the tobacco substances in the heated cigarette are only heated but not combusted, the harmful components and biological toxicity of the smoke are greatly reduced, and the smoke is also greatly reduced, so it is very popular.

[0003] From the position of the heat source relative to the heated cigarette, the heated cigarette is divided into center heated cigarette and circumferential (peripheral) heated cigarette. Due to circumferential heating, the temperature of the heat source is lower than that of the center heating, the temperature of the periphery of the cigarette is higher, the temperature of the center is lower, and the satisfaction is slightly worse than that of the center heated cigarette. The heat source directly contacts and heats the cigarette paper, and the paper burning smell such as "wooden gas" is slightly larger. In terms of sensory quality of heated cigarettes, center heated cigarettes are better than circumferential heated cigarettes.

[0004] However, when the center heated cigarette is smoked, the heat source of the heating device directly contacts and heats the tobacco substance, and the tobacco substance is carbonized, sintered and coked due to heating, which is easy to adhere to the heating element. When the cigarette is smoked, the cigarette is difficult to pull out, the tobacco substance is separated from the cigarette paper, and the whole is left in the heating cavity of the heating device, which causes cleaning difficulty and greatly reduces the smoking experience of consumers. SUMMARY

[0005] To solve the technical problem of the center heated cigarette remaining in the heating cigarette device after smoking in the prior art. The present application provides a center heated cigarette easy to pull out of a heating cigarette device, which maintains the advantages of good satisfaction and less miscellaneous gas of the center heated cigarette, and when the cigarette is smoked and pulled out of the heating cigarette device, the cigarette is easy to pull out as a whole, the tobacco substance is not separated from the cigarette paper, and the smoking experience of consumers is improved. At the same time, the present technical solution provides a method for testing the adhesion between the tobacco substance and the heating element and the adhesion between the tobacco substance and the coating material after smoking of the heated cigarette.

[0006] The present application provides a center heated cigarette easy to pull out of a heating cigarette device, and the specific technical solution is as follows, which comprises: a tobacco section and a filter rod section.

[0007] The tobacco section and the filter rod section are connected by tipping paper and arranged in line along the axial direction.

[0008] The tobacco segment is formed by wrapping the outer surface of the tobacco material part with the wrapping material part;

[0009] The inner side of the wrapping material part is further provided with an adhesive part for adhering to the outer surface of the tobacco material part.

[0010] Preferably, the adhesive part covers an area of 10-60% of the area of the tobacco material part projected onto the inner side of the wrapping material part.

[0011] Preferably, the tobacco material part is one or a mixture of reconstituted tobacco leaf and silk-like tobacco leaf.

[0012] Preferably, the reconstituted tobacco leaf specifically includes one or a combination of silk-like roller-pressed reconstituted tobacco leaf and silk-like thick paste reconstituted tobacco leaf.

[0013] Preferably, the reconstituted tobacco leaf further contains an atomizing agent, which is one or a combination of glycerol and propylene glycol.

[0014] Preferably, the adhesive part on the inner side of the wrapping material part has a coating pattern of one of a dot, a line, and a surface.

[0015] Preferably, the adhesive part is arranged on the inner side of the wrapping material part along the circumference of the outer surface of the tobacco material part.

[0016] Preferably, the adhesive parts are evenly distributed on the inner side of the wrapping material part.

[0017] Preferably, the adhesive part is one or a combination of water-based glue and hot melt glue for cigarettes.

[0018] A test method for easily pulling out a center-heating cigarette from a heating device, the specific steps are as follows:

[0019] S1, covering the end surface of the tobacco material part with a temperature-resistant film and tightly adhering and fixing the film to the outer surface of the tobacco segment;

[0020] S2, after the tobacco segment is smoked, the tobacco segment is fixed, the maximum pulling force N1 of the heating device is measured when the tobacco segment is pulled out, and the maximum pulling force N1 can represent the adhesion between the tobacco segment and the heating device;

[0021] S3, the film on the end surface of the tobacco segment is torn off, the tobacco segment is fixed, and the maximum pulling force N2 of the tobacco material part is measured when the tobacco material part is pulled out, and the maximum pulling force N2 can represent the adhesion between the tobacco material part and the wrapping material part.

[0022] In order to solve the current prior art, when the heated cigarette is pulled out of the heating smoking set after smoking, it is difficult to pull out the cigarette, the tobacco material section and the cigarette paper are separated, and the whole is left in the heating cavity of the heating smoking set, resulting in cleaning difficulty.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

Therefore, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" or "several" is two or more, unless otherwise explicitly and specifically limited.

[0036] It should be understood that the structures, proportions, sizes, etc. shown in the drawings of the present application are only used to cooperate with the content disclosed in the description, to enable those skilled in the art to understand and read, and do not have technical significance, and any modification of the structure, change of the proportion relationship or adjustment of the size, which does not affect the effects and purposes that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application.

[0037] The center heating cigarette provided by the present application is easy to pull out and heat a heating smoking set. The specific structure of the center heating cigarette includes a tobacco section and a filter rod section.

[0038] The tobacco segment and the filter rod segment are connected by tipping paper and are arranged in line along the central axis direction to form a complete cigarette structure for a consumer to smoke, wherein the tobacco segment is formed by wrapping the outer surface of the tobacco material portion 1 with a wrapping material portion 3, specifically, the wrapping material portion 3 is connected to the tobacco material portion 1 by lamination, and the tobacco segment and the filter rod segment are cylindrical structures with the same diameter, which is convenient for the consumer to take out from the cigarette box.

[0039] The present application also provides that the inside surface of the wrapping material portion 3 is provided with an adhesive portion 2 connected to the tobacco material portion 1, so that when the wrapping material and the tobacco material portion are relatively displaced after smoking, the adhesive portion 2 provides a pulling force in addition to the friction force. In addition to using the adhesive portion 2 to provide the pulling force, the size of the area of the adhesive portion 2 is also one of the important improvements of the present technical solution. In the present technical solution, the coating area of the adhesive portion 2 on the inside surface of the wrapping material portion 3 is 10%-60% of the area of the tobacco material portion 1 projected onto the inside surface of the wrapping material portion 3. For the coating area of the adhesive portion 2, the inventor has concluded through experiments that as long as the coating area of the adhesive portion 2 is within 10%-60%, the adhesive force between the tobacco material portion 1 and the wrapping material portion 3 can be greater than the adhesive force between the tobacco material portion 1 and the heating element, thereby avoiding being adhered to the heating element.

[0040] Compared with the prior art, whether it is a traditional cigarette or a heated cigarette, the wrapping material is only wrapped on the outside of the tobacco material portion, and the wrapping material and the tobacco material portion have a simple mechanical wrapping relationship, without adding and applying any substance, and without being adhered to each other. When the wrapping material and the tobacco material portion are relatively displaced, only friction exists, and the friction is often less than the adhesive force between the tobacco material portion and the heating element.

[0041] It is found that after smoking with a central heating smoking set, the tobacco material portions of the heated cigarette are closely and strongly adhered to each other, and the tobacco segment is in the form of a cylinder as a whole. After the central heating element of the heating smoking set is heated at 300-350℃ for several minutes, the tobacco portion is carbonized, sintered and coked, and is closely adhered to the heating element, and at the same time, the tobacco material portions in the tobacco portion are also closely and strongly adhered to each other. Moreover, compared with the tobacco material portions, the surface of the central heating element is relatively flat, while the tobacco material portions may be overlapped, staggered, entangled and adhered to each other. Therefore, after smoking the cigarette, the degree of adhesion of the tobacco portion to the heating element is less than the degree of adhesion of the tobacco material portions in the tobacco portion to each other.

[0042] The technical scheme is based on the above findings of the inventor and force analysis of the center heating cigarette during pulling out, and finds that since the tobacco section after being smoked by the center heating smoking set is a closely adhered columnar whole, and the adhesion between the tobacco section and the heating element is less than the adhesion between the tobacco material sections, only the adhesion part 2 between the tobacco material section 1 and the covering material section 3 needs to be added, and the material with adhesion capacity is arranged to better adhere the tobacco material section 1 and the covering material section 3, and the adhesion between the tobacco material section 1 and the covering material section 3 is greater than the adhesion between the tobacco material section 1 and the heating element, so that when the cigarette is pulled out from the heating smoking set after being smoked, the tobacco material section 1 and the cigarette paper do not separate, the whole is left in the heating cavity of the heating smoking set, the cigarette can be pulled out as a whole, and the smoking experience of the consumer is greatly improved.

[0043] Preferably, in the technical scheme, through actual production test, it is found that the coating area of the adhesion part 2 on the inner side of the covering material section 3 is in the range of 10%-60% of the area of the tobacco material section 1 projected to the inner side of the covering material section, so as to provide better adhesion between the tobacco material section 1 and the covering material section 3.

[0044] Further, in the technical scheme, in order to provide more smoking experience for consumers, the smoking material in the tobacco material section 1 is one or a combination of reconstituted tobacco leaf and filamentous tobacco leaf, so as to obtain different experiences.

[0045] Further, since the reconstituted tobacco leaf also has various process methods, the reconstituted tobacco leaf in the technical scheme specifically includes one of filamentous roller pressing reconstituted tobacco leaf and filamentous thick paste reconstituted tobacco leaf and a combination thereof, and the reconstituted tobacco leaf obtained by using different manufacturing methods can bring more combined smoking experience to consumers for personalized selection.

[0046] Further, when the aerosol generated by heating the reconstituted tobacco leaf in the tobacco material section 1 is incomparable to the filamentous tobacco leaf in terms of the complete simulation of the filamentous tobacco leaf, the reconstituted tobacco leaf also has an atomizing agent added, and the specific components of the atomizing agent are one or a combination of glycerol and propylene glycol, which provides flavor during combustion to simulate the filamentous tobacco.

[0047] Preferably, as an important part of the adhesion between the tobacco material section 1 and the covering material section 3, the coating pattern of the adhesion part 2 on the inner side of the covering material section 3 also determines the size of the adhesion, and in the technical scheme, the coating pattern of the adhesion part 2 is one of point, line and surface.

[0048] Further, the adhesive part 2 is arranged along the circumferential direction of the outer surface of the tobacco material part 1 on the inner surface of the covering material part 3, and a plurality of connection rings are formed by connecting the adhesive parts 2 end to end, and a plurality of the connection rings are arranged along the axial direction of the tobacco material part 1 and arranged on the inner surface of the covering material part 3.

[0049] Further, in order to provide more stable adhesive force, the adhesive parts 2 are uniformly distributed on the inner surface of the covering material part 3.

[0050] Preferably, the adhesive part 2 is made of one of a water-based glue and a hot melt glue for cigarettes or a combination thereof, and specifically, the adhesive part 2 is selected as a water-based glue for cigarettes as the adhesive material, because for the adhesive material for cigarettes, whether the water-based glue or the hot melt glue is used, the adhesive performance is sufficient to meet the performance requirements, and however, the negative impact of the water-based glue on the sense is smaller than that of the hot melt glue, and therefore, the water-based glue is more suitable in the technical solution.

[0051] As a preferred, the technical solution is also directed to a test method for the adhesive force between the tobacco part and the heating element after the heating cigarette is smoked, and the adhesive force between the tobacco material part 1 and the covering material part 3, and the specific steps are as follows:

[0052] S1, a temperature-resistant film connected with a measuring instrument is used to cover the end surface of the tobacco material part 1 and tightly fixed on the outer surface of the tobacco segment;

[0053] S2, the heating smoking set is inserted into the tobacco segment, and simulated combustion smoking is performed, and after the tobacco segment is smoked, the tobacco segment is fixed, the heating smoking set is pulled out, the maximum pulling force N1 at this time is measured, and the maximum pulling force N1 can represent the adhesive force between the tobacco segment and the heating smoking set;

[0054] S3, the film on the end surface of the tobacco segment is torn off, the tobacco segment is fixed, and the tobacco material part 1 is pulled out, and the maximum pulling force N2 of the tobacco material part 1 at this time is measured, and the maximum pulling force N2 can represent the adhesive force between the tobacco material part 1 and the covering material part 3.

[0055] The following will be described with reference to Figures 1 to 6 The center heating cigarette provided by the application is easy to pull out the heating smoking set, and three specific embodiments are described in detail.

[0058] Further, in the embodiment, as shown in Figure 1 With Figure 2 the adhesive part 2 on the inner side of the coating material part 3 is in a planar form and is circumferentially arranged on the inner side of the coating material part 3, and through the planar coating form, the uniform adhesive force between the tobacco substance part 1 and the coating material part 3 can be better provided.

[0059] Further, in the embodiment, the tobacco substance part 1 is in a form of filament tobacco, which is as much as possible to restore the smoking experience of traditional cigarettes, and an atomizing agent is added in the tobacco substance part 1; specifically, the atomizing agent is glycerol, and the mass content of the atomizing agent in the filament tobacco is 12%.
