Description
Technical Field
The invention relates to a tobacco particle type heating non-combustible cigarette and a manufacturing method thereof, belonging to the technical field of novel tobacco products.
Background
In recent years, with the promulgation and implementation of the 'tobacco control framework convention', tobacco control measures of various national governments are becoming stricter, the supervision legislation on tobacco is becoming stricter, the call for smoke control and smoke return is becoming stronger, and the competitive pressure of domestic and foreign markets is continuously increasing. Meanwhile, as the living standard of people is continuously improved, people pay more attention to physical and mental health and environmental protection, and new knowledge is provided for tobacco.
For example, the development of traditional cigarettes is more and more restricted due to the reasons, and statistics data in 2011 shows that other types of tobacco products show a rapid growth trend while the sales of cigarettes are reduced worldwide, the structure of the world tobacco market products is continuously changed deeply, and the active development of the whole series of tobacco products gradually becomes the strategic orientation of all nationwide tobacco companies. Currently, three main new types of tobacco products have emerged in the market: heating non-combustible tobacco products, electronic cigarettes and smokeless tobacco products. The heating non-burning tobacco product is a novel tobacco product which generates a smoke releasing effect by heating tobacco materials in different forms, starts from the 80 th century of 20 th century and is one of important products of the novel tobacco product.
The heating non-burning tobacco products generally transmit the tobacco flavor to consumers in a heating non-burning mode, and the appearance and the consumption mode of the heating non-burning tobacco products are similar to those of traditional cigarettes, so that the heating non-burning tobacco products adapt to and meet the physiological needs and psychological needs of consumers to a certain extent. The heating and non-burning mode ensures that the tobacco is heated only at a lower temperature (generally lower than 500 ℃), thereby avoiding tar and a large amount of harmful compounds generated by high-temperature burning of the tobacco, and avoiding the generation of second-hand smoke and the influence on public environment because of basically no side-stream smoke. In recent years, a great deal of tobacco manufacturing enterprises and research institutions have seen great potential for heating non-combustible tobacco products, and heavy gold is put into the field and harvested quite well. The electric heating non-combustion tobacco product has the advantages of controllable heating temperature, flexible heating mode, convenient and fashionable use and the like, has higher attention, and is an important development direction of the current domestic and foreign heating non-combustion tobacco product.
The technical core of the heating non-combustible tobacco products mainly comprises two aspects of a heat source and a smoke releasing material. The heat source types are classified into three types of electric heating, carbon heating, and chemical reaction heating, wherein both electric heating and carbon heating have been applied to products such as "iQOS" of Feimony corporation and "Revo" of Reynolds tobacco corporation. The smoke releasing material is a key factor affecting the smoking experience of the heated non-combustible tobacco products, and the smoke releasing material developed at present mainly comprises cut tobacco, tobacco dust, tobacco sheets and the like. The materials can release smoke with tobacco characteristic aroma under different heating environments, but the materials have the defects of uneven heating, easy carbonization, inconvenient operation and the like. The problems of small smoke amount, uneven smoke generation, easy coking and the like exist in the tobacco shreds and the tobacco dust because the atomizing agent is difficult to add; while the tobacco sheet used by the iQOS solves the problem of smoke generation, the manufacturing process is complex, the equipment cost is expensive, the controllability is not strong, and the smoke has heavy burnt paper taste, so that the taste is affected. Meanwhile, after the existing product is used, smoke release materials can remain on the electric heating assembly due to coking, carbonization, bonding and the like, and a special tool is required to be matched for cleaning the heating assembly; furthermore, the existing sheet-type heating non-combustible cigarettes are directly pulled out after the smoking is finished, and tobacco shreds can fall into a smoking set heating chamber, so that an auxiliary pulling-out component for cigarettes is needed.
In order to solve the above problems of tobacco products using cut tobacco, tobacco powder and tobacco flakes as a smoke releasing material, patent CN108065456A, CN108143003A, CN 108143005A, CN 108185524a and the like propose a heating non-burning tobacco product using tobacco particles as a smoke releasing material, but the following problems are all presented: the cigarette has complex structural design; the tobacco particles have poor encapsulation effect and low efficiency; the selected tobacco particle-bearing plugging material shrinks under heated conditions, causing the particles to fall off. Therefore, a novel heating non-combustion tobacco product which is sufficient and uniform in smoke release, free of tobacco particles falling and capable of directly pulling out cigarettes is urgently required to be developed.

Detailed Description
The following describes in detail the examples of the present invention, which are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of protection of the present invention is not limited to the following examples.
As shown in fig. 1, a tobacco particulate heated non-combustible tobacco product comprises a tobacco particulate segment 1 and a filter segment. The tobacco particle section 1 is characterized in that a front end blocking structure 13 and a tail end blocking structure 14 are respectively fixed at the front end and the tail end of a paper hollow pipe 11, and tobacco particles 12 are filled between the front end blocking structure 13 and the tail end blocking structure 14; the trailing end closure structure 14 is adjacent to the filter segment. The filter tip section comprises a first cooling section 2, a second cooling section 3 and a filtering section 4 which are connected in sequence; the first cooling section 2 is positioned near the tobacco particle section 1 and the filtering section 4 at the lip end. The paper hollow tube of the tobacco particle section 1 and the first cooling section 2 are wrapped with airtight molding paper 5 to form a paper hollow tube/first cooling section binary composite rod; the second cooling section 3 and the filtering section 4 are wrapped with high air permeability forming paper 6 to form a second cooling section/filtering section binary composite rod; the paper hollow tube/first cooling section binary composite rod is rubbed with the second cooling section/filtering section binary composite rod through trademark paper 7. The label paper wraps all of the second cooling section/filtering section binary composite rod and wraps the first cooling section by 5 cm.
The front end blocking structure 13 and the rear end blocking structure 14 are both in a bottle cap shape, and as shown in fig. 2, the front end blocking structure 13 includes a circular sheet-shaped cap portion 131 and a skirt portion 132 having raised folds and recessed teeth, and the cap portion is provided with a plurality of through holes. The front end plugging structure 13 is adjacent to tobacco particles in the paper hollow pipe by the cover part, the skirt part is adhered and fixed on the inner wall of the paper hollow pipe 11, and the top end of the skirt part is flush with the front port of the paper hollow pipe 11; the tail end plugging structure 14 is plugged into the paper hollow tube 11 by the tobacco particles in the paper hollow tube with the skirt part, and the bottom end of the cover part is flush with the tail end opening of the paper hollow tube 11. The skirt parts of the tail end plugging structure and the front end plugging structure adopt a beer bottle cap type structure with raised folds and concave tooth openings, so that the contact area with the inner wall of the paper blank pipe can be increased, and sliding is avoided; and the bonding strength of the front end plugging structure on the inner wall of the paper blank pipe can be ensured. The lid of tail end plugging structure is arranged in preventing tobacco particles from dropping into cavity mouth stick, and the lid of front end plugging structure is arranged in preventing tobacco particles from dropping out of the cigarette from the paper blank pipe.
The tobacco particulate material used in this example is described in example 1 of patent CN108143003 a.
In particular, the front end blocking structure 13 is made of aluminum foil lining paper (in this embodiment, the gram weight is 45g/m 2 ) The material used for the tail end plugging structure 14 is aluminum foil (in this embodiment, 40 μm thick). When the cigarettes are sucked, cold air enters from the front end plugging material aluminum foil lining paper and is mixed with smoke released by heating tobacco particles to form hot air flow, and the hot air flow enters the filter tip section after flowing through the tail end plugging material aluminum foil. Therefore, the end sealing material adopts aluminum foil, has good heat resistance, can not release harmful components when heated, and has certain cooling effect. The front end plugging material adopts the aluminum foil lining paper, and the lining paper surface of the aluminum foil lining paper and the inner wall of the paper blank pipe are required to be bonded together through an adhesive, so that the bonding strength is far better than that between the aluminum foil surface and the inner wall of the paper blank pipe. In addition, the aluminum foil lining paper is also better than the paper which is directly used as the front end plugging material, and the originalBecause of the existence of the metal aluminum foil in the aluminum foil lining paper, the plasticity and the permeability resistance of the aluminum foil lining paper are better than those of paper.
In the concrete implementation, the diameters of the through holes of the cover parts of the front end plugging structure 13 and the tail end plugging structure 14 are 0.05-0.4mm, and the hole edge distance is 1-2mm; the skirt height of the leading end closure structure 13 and the skirt height of the trailing end closure structure 14 are both 1.0-2.5mm. If the diameter of the through hole is lower than 0.05mm, the suction resistance is overlarge, the smoke volume is small, and the suction experience is poor; if the diameter of the through hole is higher than 0.4mm, tobacco particles can be caused to fall. If the skirt part of the front end plugging structure is lower than 1.0mm, the bonding strength of the front end plugging structure and the paper blank pipe is insufficient, and the risk that the plugging structure falls off due to weak bonding exists; if the skirt part of the rear end plugging structure is lower than 1.0mm, the contact area of the skirt part and the paper blank pipe is low, and the risk of sliding of the plugging structure exists. If the height of the skirt part of the front end plugging structure is more than 2.5mm, the effective filling quantity of tobacco particles can be reduced, the preparation difficulty can be brought, and the production efficiency can be reduced; if the height of the skirt part of the rear end plugging structure is more than 2.5mm, materials are wasted, and high-speed production is not facilitated. In this embodiment: the diameter of the through hole of the cover part of the front end plugging structure 13 is 0.2mm, the pitch of the hole is 1mm, and the height of the skirt part is 2mm; the diameter of the through hole of the cover part of the tail end plugging structure is 0.1mm, the hole edge distance is 1mm, and the height of the skirt part is 2mm.
In practice, a layer of aluminum foil is adhered to the inner layer of the paper hollow tube 11. The aluminum foil layer has excellent barrier function and can effectively prevent the exudation of chemical substances in tobacco particles during storage or suction.
In specific implementation, the outer diameter of the paper hollow tube 11 is 22.0-24.0mm, the wall thickness is 0.2-0.4mm, and the length is 12-20mm. In this example, the paper blank tube had an outer diameter of 22.5mm, a wall thickness of 0.2mm and a length of 15mm.
In specific implementation, the first cooling section 2 is a special-shaped acetate fiber tip rod containing phase change materials, and the special-shaped structure of the special-shaped acetate fiber tip rod is positioned at the periphery and/or inside the tip rod. As shown in figure 3, the special-shaped structure at the periphery of the filter rod is that 3-5V-shaped grooves 2a are uniformly distributed on the cylindrical surface of the filter rod along the circumferential direction, and the volume of each groove accounts for 10-20% of the volume of the whole filter rod; the special-shaped structure inside the filter rod is that a cavity which is penetrated along the axial direction of the filter rod is arranged in the central axis of the filter rod, the cross section of the cavity is round, triangular (as shown in figure 4, 2b is a cavity with triangular cross section), quadrilateral, pentagram, hexagram or heptagram, and the volume of the cavity accounts for 7-18% of the volume of the whole filter rod. The phase change material is polyethylene glycol with the molecular weight of 4000-40000, and is evenly sprayed on cellulose diacetate during the processing of the special-shaped acetate fiber tip rod; the mass of the phase change material accounts for 10-30% of the total mass of the special-shaped acetate fiber tip rod. In this embodiment, the special-shaped structure of the special-shaped acetate fiber tip rod used as the first cooling section 2 is that 5V-shaped grooves 2a are uniformly distributed on the cylindrical surface of the tip rod along the circumferential direction, the groove volume accounts for 15% of the whole volume of the tip rod, the phase-change material is polyethylene glycol with molecular weight of 6000, and the mass of the phase-change material accounts for 20% of the total mass of the special-shaped acetate fiber tip rod.
In specific implementation, the polylactic acid tip rod used as the second cooling section 3 is formed by wrapping polylactic acid cooling material 32 in forming paper 31 of the second cooling section; the polylactic acid cooling material is a strand polylactic acid or a noodle polylactic acid; the diameter of the strand polylactic acid is 50-300 mu m; the width of the noodle-shaped polylactic acid is 0.5-2.0mm, and the thickness is 25-50 mu m; when the tow-shaped polylactic acid is adopted, the suction resistance of the polylactic acid filter tip is 300-1000pa/100mm; when the noodle-shaped polylactic acid is adopted, the suction resistance of the polylactic acid filter tip is 100-400pa/100mm. In this example, a 100 μm diameter tow-like polylactic acid was used, and the suction resistance of the tip was 500pa/100mm.
The phase change material has the characteristic of absorbing and storing heat, and the temperature of smoke can be reduced by adding the polyethylene glycol phase change material into the special-shaped acetate fiber tip rod. However, the special-shaped filter tip containing the phase change material is difficult to reduce the temperature of the smoke to the acceptable temperature of the cavity due to the large longitudinal airflow channel, so that the polylactic acid cooling rod is adopted to cool together with the smoke. Polylactic acid in the polylactic acid filter tip is in a tow shape or a noodle shape, has larger specific surface area, and is more fully contacted with smoke, so that the cooling effect is better. However, if all the polylactic acid filter sticks are used, the smoke is trapped to be too large, and the smoke amount is low, so that two cooling sticks are selected for use in a matched mode. For the first cooling section: the volume of the groove or the cavity is too low, so that the flue gas can be greatly trapped; the volume of the groove or the cavity is too high, and the cooling effect is greatly reduced. For the second cooling section: if the tow-shaped polylactic acid is adopted, when the suction resistance exceeds 1000pa/100mm, the smoke interception is serious, and when the suction resistance is lower than 300pa/100mm, the effective cooling area of the material is low, and the cooling effect is limited; if the strip polylactic acid is adopted, the cooling effect is limited when the absorption resistance is lower than 100pa/100mm, and the smoke can be greatly intercepted when the absorption resistance is higher than 400pa/100mm.
In specific implementation, the acetate fiber tip rod used as the filtering section is formed by wrapping cellulose acetate 42 with forming paper 41 of the filtering section; when the filter section adopts the special-shaped acetate fiber tip rod, the special-shaped structure is a cavity which is arranged in the middle shaft of the tip rod and is penetrated along the axial direction of the tip rod, and the volume of the cavity is not higher than 10% of the volume of the whole special-shaped acetate fiber tip rod; when the filter section adopts a solid acetate fiber tip rod, the suction resistance is not higher than 1000pa/100mm. The filter section of this embodiment adopts a solid acetate fiber tip rod with a suction resistance of 1000pa/100mm
The specific implementation method comprises the following steps: the length of the first cooling section 2 is 7-12mm, and the diameter is 22.0-24.0mm; the length of the second cooling section 3 is 15-18mm, and the diameter is 22.0-24.0mm; the length of the filtering section 4 is 7-10mm, and the diameter is 22.0-24.0mm; the diameters of the tobacco particle section 1, the first cooling section 2, the second cooling section 3 and the filtering section 4 are the same. In this embodiment, the diameters of the sections are 22.5mm, and the lengths of the first cooling section 2, the second cooling section 3 and the filtering section 4 are 10mm, 15mm and 10mm respectively.
The embodiment also provides a manufacturing method of the tobacco particle type heating non-combustion tobacco product, which comprises the following steps:
