Description

Technical Field

[0001] The invention belongs to the technical field of heated cigarette flavoring, and in particular relates to a programmable slow-release component and a heated cigarette. Background Art

[0002] As a new type of tobacco product, heated cigarettes have developed rapidly in recent years. They heat tobacco by "heating without burning", but like traditional cigarettes, they produce visible smoke. The non-burning feature greatly reduces the harmful substances in their smoke. However, when smoking heated cigarettes, an external heat source is required to heat the tobacco matrix. As the smoking time increases, the state of the tobacco matrix is ​​constantly changing, causing the composition of the smoke aerosol to constantly change, especially for tobacco flavor components, making the aroma components inconsistent from puff to puff. It is necessary to add fragrance to heated cigarettes to solve this problem.

[0003] The main flavoring methods for heated cigarettes currently include tobacco mixed with spices, built-in popping beads, and adding scented wires, but the built-in popping beads require manual squeezing to release the popping beads before smoking, while the mixed spices and added scented wires have poor sealing properties, are prone to cross-flavoring, and have distorted flavors. In addition, compared with traditional cigarettes, heated cigarettes produce relatively less smoke during the smoking process. How to increase the amount of smoke produced by heated cigarettes during the smoking process is a problem that needs to be solved. Summary of the invention

[0080] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the drawings.

[0081] As Figures 1-2 shown is an embodiment of the present invention, which provides a flavor composite unit 10 as a programmable slow-release component. The flavor composite unit 10 is used in a heated cigarette. The flavor composite unit 10 includes a carrier layer 11, at least one flavor cartridge 12, and at least one smoke agent cartridge 13; the flavor cartridge 12 and the smoke agent cartridge 13 are independently distributed on the surface of the carrier layer 11; in the suction state of the heated cigarette, the smoke generated by suction flows along the axial direction of the carrier layer 11 to pass through the flavor cartridge 12 and the smoke agent cartridge 13, so that the flavor cartridge 12 and the smoke agent cartridge 13 are heated and cracked under the action of the temperature of the smoke, and the flavor and the smoke agent are respectively released within 2 puffs of smoke. As an example, the heated cigarette sequentially includes a smoke generation section 40, a cooling section 30, and a filter section 20. The lengths of the smoke generation section 40, the cooling section 30, and the filter section 20 are 12 mm, 26 mm, and 7 mm respectively. The total length of the flavor composite unit 10 is consistent with the length of the cooling section 30, which is convenient for accurately cutting the cooling section 30 of each cigarette in subsequent processes.

[0082] Specifically, the heat-cracking temperatures of the flavor cartridge 12 and the smoke agent cartridge 13 are 50 - 60 °C, 60 - 70 °C, 70 - 80 °C, or 80 - 90 °C.

[0083] Specifically, due to different design types of materials selected for different heated cigarettes, the flavor composite unit 10 as a programmable slow-release component adjusts the release order of the flavor cartridge 12 and the smoke agent cartridge 13 according to the taste effect required by the heated cigarette.

[0084] Optionally, when the amount of self-generated smoke of the heated cigarette is insufficient, in order to achieve a better olfactory effect of the cigarette smell, the heat cracking temperature of the flavor cartridge 12 can be made higher than that of the smoke agent cartridge 13. That is, when sucking on the heated cigarette, the smoke agent cartridge 13 releases the smoke agent first to increase the amount of smoke, and then the flavor cartridge 12 releases the flavor. Further, as Figure 3A shown, the smoke agent cartridge 13 is arranged at a position with a higher temperature near the smoke generating section to accelerate the heat cracking of the smoke agent cartridge, so as to release the smoke agent first.

[0085] Optionally, when both the self-generated aroma and the amount of smoke of the heated cigarette are insufficient, in order to achieve a better olfactory effect of the cigarette smell, the heat cracking temperature of the flavor cartridge 12 can be made equal to that of the smoke agent cartridge 13. That is, when sucking on the heated cigarette, the smoke agent cartridge 13 and the flavor cartridge 12 release the smoke agent and the flavor simultaneously. Further, as Figure 3B shown, the flavor cartridge 12 and the smoke agent cartridge 13 are arranged simultaneously at a position with a higher temperature near the smoke generating section to accelerate the heat cracking of the flavor cartridge 12 and the smoke agent cartridge, so as to release the flavor and the smoke agent simultaneously.

[0086] Optionally, when the self-generated aroma of the heated cigarette is insufficient, in order to achieve a better olfactory effect of the cigarette smell, the heat cracking temperature of the flavor cartridge 12 can be made lower than that of the smoke agent cartridge 13. That is, when sucking on the heated cigarette, the flavor cartridge 12 releases the flavor first, and then the smoke agent cartridge 13 releases the smoke agent. Further, as Figure 3C shown, the flavor cartridge 12 is arranged at a position with a higher temperature near the smoke generating section to accelerate the heat cracking of the flavor cartridge 12, so as to release the flavor first.

[0087] Specifically, the thickness of the carrier layer 11 is 40 - 45 μm, 45 - 50 μm, 50 - 55 μm, 55 - 60 μm, 60 - 65 μm or 65 - 70 μm.

[0088] Specifically, there is at least one flavor cartridge 12, and the flavor is an oily flavor. If it is a particulate flavor, the characteristic aroma is not as obvious as that of the oily liquid. Among them, the oily flavor does not undergo physical or chemical reactions with the wrapping layer and the encapsulation layer of the flavor cartridge 12.

[0089] Specifically, the flavor loading amount in the single flavor cartridge 12 is 20 - 22 μl, 22 - 24 μl, 24 - 26 μl, 26 - 28 μl or 28 - 30 μl.

[0090] Specifically, there is at least one smoke agent cartridge 13, and the smoke agent is propylene glycol and / or glycerol.

[0091] Specifically, the volume ratio of the flavor cartridge 12 to the smoke agent cartridge 13 on the loading layer 11 is 0.3 - 0.5, 0.5 - 0.7, 0.7 - 1.0 or 1.0 - 1.5. If the ratio is not within this range, it will cause the smoke amount of the smoke agent to be too large, but there is no characteristic fragrance, and for the smoking assessors, the actual sensory experience is not good.

[0092] Specifically, the loading volume of the flavor accounts for 0.25 - 0.35, 0.35 - 0.45, 0.45 - 0.55, 0.55 - 0.65 or 0.65 - 0.75 of the total volume of the flavor cartridge 12, that is, the loading volume of the flavor is 1 / 4 to 3 / 4 of the total volume of the flavor cartridge 12. Within this range, the release of the characteristic fragrance has good consistency and continuous stability.

[0093] Specifically, the loading volume of the smoke agent accounts for 0.25 - 0.35, 0.35 - 0.45, 0.45 - 0.55, 0.55 - 0.65 or 0.65 - 0.75 of the total volume of the smoke agent cartridge 13.

[0094] Specifically, the flavor cartridge 12 and the smoke agent cartridge 13 are axially spaced apart or axially juxtaposed. Preferably, the flavor cartridge 12 and the smoke agent cartridge 13 are centered on the surface of the loading layer 11, arranged at intervals, and evenly distributed. Within 2 puffs, that is, when the flue gas passes through the flavor cartridge 12 and the smoke agent cartridge 13 twice, the flavor and the smoke agent can be dissolved and released. The dissolution rates of multiple units are basically the same. More specifically, the closer the flavor cartridge 12 and the smoke agent cartridge 13 are to the smoking section 40, the faster the release rate. The release order of the flavor cartridge 12 and the smoke agent cartridge 13 can be set according to the actual design requirements of a specific heated cigarette, that is, the order can be set according to the focus of the smoke amount and fragrance in the first puff.

[0095] The flavor composite unit 10 device of the present invention is used on a heated cigarette. When using a 1 ml syringe to inject about 0.5 ml of glycerol into the smoking section 40 of the heated cigarette, during the process of sucking on the heated cigarette, it can be visually observed that the smoke amount increases significantly. At the same time, the characteristic fragrance of the flavor can be significantly sucked in the flue gas within 2 puffs.

[0096] Specifically, the flavor cartridge includes a flavor encapsulation layer, a flavor wrapping layer and a flavor; the flavor is loaded in the flavor wrapping layer and sealed by the flavor encapsulation layer. The flue gas generated by sucking transfers heat to the flavor encapsulation layer, and the flavor encapsulation layer is cracked by heating to break the sealing structure, thereby releasing the flavor. The material of the flavor encapsulation layer includes one or a combination of several of polyacrylate, polyhydroxyalkanoate, polyethylene, polypropylene, polybutylene succinate and polylactic acid.

[0097] Specifically, the smoke agent cartridge includes a smoke agent encapsulation layer, a smoke agent wrapping layer, and a smoke agent; the smoke agent is loaded in the smoke agent wrapping layer and sealed by the smoke agent encapsulation layer. The smoke generated by suction transfers heat to the smoke agent encapsulation layer, and the smoke agent encapsulation layer is cracked by heat to destroy the sealing structure, thereby releasing the smoke agent. The material of the smoke agent encapsulation layer includes one or a combination of polyacrylate, polyhydroxyalkanoate, polyethylene, polypropylene, polybutylene succinate, and polylactic acid.

[0098] Furthermore, the spice cartridge 12 has the same structure as the smoke agent cartridge 13, that is, the spice wrapping layer and the smoke agent wrapping layer, and the spice encapsulation layer and the smoke agent encapsulation layer have the same structure. Therefore, the dissolution and release rates of the spice cartridge 12 and the smoke agent cartridge 13 are basically the same, and the release order of the spice and the smoke agent is controlled respectively by the arrangement order on the carrier layer 11.

[0099] As an example, as Figure 4 shown, the spice cartridge 12 includes a spice encapsulation layer 121, a spice wrapping layer 122, and a spice 123. The spice 123 is loaded in the spice wrapping layer 122 and sealed by the spice encapsulation layer 121. In the suction state of the heated cigarette, the smoke generated by heating passes through the spice encapsulation layer 121 to reach the user's mouth, and the temperature of the smoke is transferred to the spice encapsulation layer 121 to cause deformation by heat, so that the spice 123 starts to be released in the heated cigarette at least before the second puff of smoke is inhaled, so that its characteristic fragrance reaches the user's mouth with the second puff of smoke inhaled by the user and can be sensed. The spice cartridge 12 is an independent sealed cartridge structure before suction, preventing the built-in spice 123 from mixing with other raw materials of the heated cigarette before suction, resulting in a distorted fragrance. Generally, when the user inhales the first puff of smoke of the heated cigarette, they are more stimulated by temperature, the aroma of the tobacco itself, etc., and the attention to the aroma release of the flavoring spice 123 is relatively small. Therefore, when the second puff of smoke is inhaled, the characteristic fragrance of the spice 123 is released into the mouth with the second puff of smoke, which is beneficial to further improve the user's experience.

[0100] As an example, the spice wrapping layer 122 has at least one opening for pouring in the spice 123. After the spice 123 is poured in, the opening is sealed by the spice encapsulation layer 121, thereby forming a sealed spice cartridge 12. When entering the suction state, the spice encapsulation layer 121 will gradually melt until it completely disappears. The gradual melting and disappearance of the spice encapsulation layer 121 destroys the sealing structure, enabling the effective release of the built-in spice 123, and thus enabling the characteristic fragrance to be sensed.

[0101] Specifically, the flavor 123 is preferably in a liquid form within the flavor wrapping layer 122. If it is in a solid form such as granular, the volatilization effect is poor, which is not convenient for releasing the fragrance, and it is more difficult to ensure that the flavor starts to be released in the heated cigarette at least before the user takes the second puff of smoke. As a preferred embodiment, the flavor encapsulation layer 121 is a straight plate structure covering the opening of the flavor wrapping layer 122. The flavor wrapping layer 122 is provided with a gap in the direction of the filter rod section 20. The length of this section is the set length V21 of the gap, and the length distance of the loaded flavor 123 within the flavor wrapping layer 122 is the flavor length V22.

[0102] More specifically, the ratio of the set length V21 of the gap to the flavor length V22 is 0.3 - 0.5, 0.5 - 1.0, 1.0 - 1.5, 1.5 - 2.0, 2.0 - 2.5 or 2.5 - 3.0. Preferably, the ratio range of the set length V21 of the gap to the flavor length V22 is from 1:3 to 3:1. In the subsequent process, the flavor cartridge 12 belt will be precisely cut. Each cut flavor cartridge 12 needs to match the length of the cooling section 30 of the cigarette. Having a gap distance can ensure that the length of the flavor cartridge 12 matches the length of the cigarette cooling section 30.

[0103] More specifically, the flavor 123 includes tobacco flavors, and the tobacco flavors include flavor materials with ethanol, propylene glycol, olive oil, and / or glycerol monocaprylate as solvents. The flavor materials include any one or more of grape fragrance base, honeydew melon fragrance base, mint fragrance base, blueberry fragrance base, pineapple fragrance base, peach fragrance base, taro fragrance base, coffee fragrance base, sweet orange fragrance base, lime fragrance base, and tobacco extract.

[0104] Specifically, the thickness of the flavor encapsulation layer 121 is 0.1 - 0.2 mm, 0.2 - 0.3 mm, 0.3 - 0.4 mm, or 0.4 - 0.5 mm, which further ensures better consistency and continuous stability when the characteristic fragrance is released.

[0105] Specifically, the material of the spice encapsulation layer 121 is a temperature-deformable material, and the temperature-deformable material includes one or a combination of several high molecular materials such as ethylene-vinyl acetate copolymer (EVA), polyacrylate (PPA), polyhydroxyalkanoate (PHA), polyethylene (PE), polypropylene (PP), polybutylene succinate (PBS), and polylactic acid (PLA). It is convenient to deform and destroy the sealing performance under the action of high-temperature flue gas, so as to gradually release the spice 123, enabling the characteristic fragrance to be continuously perceived by the user. Further, to ensure that the spice starts to be released in the heated cigarette at least before the user takes the second puff of flue gas, and the release of the characteristic fragrance is consistent, the present invention uses the temperature-deformable material in cooperation with the temperature of the sucked flue gas, so that the temperature of the flue gas received by the spice encapsulation layer 121 in the suction state is 90-92°C, 92-94°C, 94-96°C, 96-98°C, or 98-100°C. Within the heating time of 1-2 s, 8-10%, 10-12%, 12-14%, or 14-16% of the spice encapsulation layer 121 made of the temperature-deformable material undergoes deformation. Furthermore, the spice wrapping layer 122 can also be made of a temperature-deformable material, so as to cooperate with the spice encapsulation layer 121 to release the spice.

[0106] As an example, the present invention Figure 5 The heated cigarette to which the spice cartridge 12 is applied is shown. Existing heated cigarette sticks usually consist of a smoking section 40, a cooling section 30, and a filter section 20. Taking a heated cigarette stick with a diameter of 7.16 mm as an example, the length of the smoking section 40 is 12 mm, the length of the cooling section 30 is 26 mm, and the filter section 20 is 7 mm. After the spice cartridge 12 is manufactured on the forming equipment, it is placed in the cooling section 30 inside the heated cigarette, and can seal the spice 123 for a long time under normal environmental conditions. The spice cartridge 12 can be placed at any position in the cooling section 30. In the present invention, the set length of the spice cartridge 12 is preferably the same as the length of the cooling section 30, both being 26 mm, which is convenient for installation and fixation.

[0107] To further illustrate the advantages of the present invention, the present invention conducts the following exploration on the compatibility relationship between the selection of the spice encapsulation layer material and the tobacco spice material.

[0108] Different materials are loaded in the spice wrapping layer of the spice compounding unit, and then sealed with spice encapsulation layers made of different materials, and the corrosion situation and surface tension situation are observed. The experimental results are shown in Tables 1 and 2.

[0109] Table 1: Evaluation table of the influence of tobacco spice solvents on the performance of the spice encapsulation layer

[0112] Flavor material PLA film EVA hot melt adhesive Droplet formation (surface tension) Suction taste Grape flavor base Severely corrosive Corrosive Good Not obvious Hami melon flavor base Corrosive Corrosive Spreads Average

[0113] From the comparison results of Table 1 and Table 2, it can be seen that when the tobacco flavor solvent is loaded in the spice wrapping layer, the anti-corrosion situation is better. When the spice wrapping layer directly loads ordinary spice materials, it will corrode the spice encapsulation layer materials, and then it is impossible to ensure the tightness of the spice slow-release unit, and it is easy to have a flavor cross-talk with other raw materials of the heated cigarette, resulting in a distorted flavor, and it is difficult to be released in the heated cigarette before the user takes the second puff of smoke. The overall puffing taste is poor. The influence of the smoke agent on the smoke agent encapsulation layer materials is similar to this situation.

[0114] The present invention further explores the influence of the tobacco flavor materials mixed with ordinary spice materials and solvents on the sealing effect of the spice encapsulation layer, observes the influence of its corrosion situation and surface tension situation, and further explores the influence of the prepared spice slow-release unit on the puffing taste in heated cigarettes. The experimental results are shown in Table 3.

[0115] Table 3: Table of the influence of tobacco flavor materials on the performance of the spice encapsulation layer

[0116]

[0117] It can be seen from Table 3 that the tobacco flavor materials have good adaptability in the spice slow-release unit, not only having the advantage of anti-corrosion, but also further maintaining the release of its characteristic flavor. In terms of the puffing experience, the characteristic flavor can be felt when taking the second puff of smoke. Among them, the spice encapsulation layer material is preferably PLA material, which has a wide range of adaptability to the selection of tobacco flavor materials. The situation of the smoke agent's selection of the smoke agent encapsulation layer material is also similar to this result. At the same time, for the tobacco flavor essence materials using propylene glycol as the solvent, their corrosiveness is weaker, their sealing retention time is longer, and the puffing taste matched with the essence materials is also relatively good. At the same time, for the tobacco flavor essence materials using propylene glycol as the solvent, when the ratio of the fragrance base to propylene glycol is lower than 7:3, their corrosiveness is weaker, their sealing retention time is longer, and the puffing taste matched with the essence materials is also relatively good.
