Description

Technical Field

[0001] The invention belongs to the technical field of tobacco, and in particular relates to a sealed heating cigarette with a plug. Background Art

[0002] With the improvement of people's living standards, the harm caused by traditional tobacco products has become increasingly prominent. New tobacco products have gradually become a realistic choice for major multinational tobacco companies to cope with the declining sales of traditional tobacco products. At present, most heat-not-burn cigarettes use air as a carrier of smoke. In order to ensure that the tobacco does not burn, the heating temperature applied is usually low, generally not exceeding 300°C, to reduce the harmful components caused by the combustion of traditional tobacco products; but the tobacco aroma components are difficult to be completely released, and the smoke volume is insufficient, so this type of cigarette is difficult to be accepted by traditional smokers; in addition, in order to ensure air circulation, the tobacco ends of most heat-not-burn cigarettes are open structures, that is, tobacco or reconstituted tobacco sheets are directly exposed to the outside, or connected to the outside atmosphere. After smoking, tobacco residues will fall off, which is easy to cause pollution to the smoking utensils. Therefore, this type of tobacco needs to spend time cleaning the smoking utensils after using it for a period of time. In order to solve the above problems, there is currently a method of sealing cigarettes through a tightening piece of a smoking utensils, which requires high precision in the production of smoking utensils, complex structure of smoking utensils, and high cost; and the problem of insufficient smoke aroma components that cannot meet the needs of smokers still exists.

[0003] The present invention has been proposed to solve the above-mentioned problems. Summary of the invention

[0004] The invention discloses a cigarette which uses a disc containing a flavoring material to seal a tobacco segment and has a smoke extraction segment. The cigarette can not only increase the heating temperature to fully release tobacco components and increase the smoke volume, but also the disc containing the flavoring material in the plug can flavor the smoke when heated, thus solving the problem that the smoke volume cannot be increased and harmful components cannot be reduced at the same time, and solving the problem that the smoke cannot be flavored.

[0005] The technical solution of the present invention is as follows:

[0006] The invention discloses a sealed heating type cigarette with a plug. The end of a tobacco segment 1 of the cigarette is sealed with a seal 5, and the seal 5 contains a flavoring material.

[0007] Preferably, the structure of the cigarette is: a sealing member 5, a tobacco segment 1, a smoke extraction segment 2, and a functional filter segment 3; the outside of the cigarette is wrapped with an external wrapping member 4; the smoke extraction segment 2 has an axial central cavity 21 and a breathable tube wall 22.

[0008] Preferably, the sealing member 5 is a disc, the diameter of the disc matches the diameter of the cigarette, and the thickness of the disc is 1.5-4 mm.

[0009] Preferably, the fume extraction section 2 is an empty tube.

[0010] Preferably, the functional filter segment 3 includes a cooling segment 31 and a filtering segment 32 .

[0011] Preferably, the tobacco segment 1 is one or more of shredded tobacco, tobacco sheets, tobacco particles, tobacco shaped bodies or tobacco-containing gel bodies.

[0012] Preferably, the seal 5 comprises a gel base material and an additive; the gel base material is one or more of sodium alginate, polyethylene glycol, sodium stearate or agar; the additive comprises natural plant powder, a smoke-generating agent and a flavor, and the smoke-generating agent is one or more of glycerol or propylene glycol.

[0013] Preferably, the method for preparing the sealing member 5 comprises the following steps:

[0014] ① Mixing the gel base material and the additive to obtain a mixture;

[0015] ② The mixture of step 1 is molded by injection molding, compression molding or film pressing, and then cut into discs to obtain the sealing member 5.

[0016] Preferably, in step ①, the gel matrix accounts for 30-50 wt% of the mixture; and the additive accounts for 50-70 wt% of the mixture.

[0017] Preferably, in the additive, natural plant powder accounts for 30-40wt%, smoke generating agent accounts for 30-40wt%, and the flavor and fragrance accounts for 20-30wt%.

[0018] The present invention has the following beneficial effects:

[0019] 1. The present invention is the first to design a sealed heating type cigarette with a disc-shaped sealing member containing a flavoring material for plugging. Regardless of the structure of the matching heating type tobacco device, the tobacco segment of the sealed heating type cigarette with a sealing member plugging the head is sealed by the disc containing the flavoring material, and the oxygen content of the tobacco segment will decrease during the heating process, that is, it can create an oxygen-deficient environment for the cigarette. At this time, even if the heating temperature is increased, combustion will not occur. Therefore, the heating temperature can be increased to fully release the tobacco flavoring components and increase the smoke volume.

[0020] 2. The sealed heating cigarette with a plug of the present invention uses a disc containing a flavoring material to seal the plug, so tobacco residues will not fall and contaminate the smoking utensil.

[0021] 3. In the sealed heating cigarette with a plug of the present invention, the smoke extraction section 2 has an axial central cavity 21 and a breathable tube wall 22. During the inhalation process, the outside air enters from the breathable tube wall 22 and mixes with the smoke generated by the heating of the tobacco section 1 in the central cavity 21 to form mainstream smoke for inhalation. At the same time, during the inhalation process, the outside air enters from the breathable tube wall 22. The air flow rate of the breathable tube wall 22 is high and the pressure is low, which has an extraction effect on the smoke of the tobacco section 1. In addition, the outside air also has a cooling effect on the smoke.

[0022] 4. In the sealed heating cigarette with a plug of the present invention, the plug seal 5 seals the tobacco segment 1. In the cigarette production process, the seal 5 can be rolled together with the tobacco segment 1, which is convenient for industrial production. If a sealing film or other components are used to seal the tobacco segment separately, the cigarette production process must be changed, and the existing equipment must be modified greatly, which is not convenient for industrial production.

[0023] 5. In the sealed heated cigarette with a plug of the present invention, the sealing member 5 of the plug contains a flavoring material. When the smoking device is heated, the sealing member 5 releases an aroma that mixes with the smoke for the smoker to inhale, thereby improving the smoker's experience. However, since the smoking device only heats the tobacco segment and does not directly heat the sealing member containing the flavoring material, the aroma in the sealing member will be slowly released and will not decompose.

[0024] 6. In the sealed heating cigarette with a plug of the present invention, the smoke extraction section 2 has an axial central cavity 21 and a breathable tube wall 22. The tube wall 22 has a certain air permeability. When the cigarette is smoked, it does not affect the inflow of external air; when not inhaled, the smoke will not escape through the tube wall 22, thereby effectively reducing the loss of smoke.

[0029] The content of the present invention is further explained below through specific implementation examples.

[0030] like Figure 1A sealed heating cigarette with a plug, the structure of the cigarette is: a sealing member 5, a tobacco segment 1, a smoke extraction segment 2, and a functional filter segment 3, the outer portion of the cigarette is wrapped with an outer wrapper 4; the tobacco segment 1 of this embodiment is a heat-not-burn upper tobacco segment 1 made of shredded tobacco, tobacco sheets, and tobacco particles; the smoke extraction segment 2 has an axial central cavity 21 and a breathable tube wall 22, and this embodiment is an empty tube formed by the breathable tube wall 22, in which there is a central cavity 21; the functional filter segment 3 includes a cooling segment 31 and a filtering segment 32;

[0031] like Figure 2 As shown, the sealing member 5 has a thickness of 2.0 mm and contains a fragrance material. The preparation method is as follows:

[0032] ① Mixing 50wt% of the gel substrate sodium alginate and agar and additives to obtain a mixture; the additives are: natural plant powder rose dry powder accounts for 30wt%, smoke agent glycerin accounts for 30wt%, and the tobacco flavor rose flavor accounts for 20wt%;

[0033] ② The mixture of step 1 is molded by injection molding, and then cut into discs with a thickness of 2.0 mm to obtain the sealing member 5.

[0034] When preparing cigarettes, the sealing member 5 and the tobacco segment 1 are rolled together with the packaging paper, which facilitates industrial production.

[0035] The sealed heating cigarette with plug of the present invention can be smoked when matched with the heating type smoking device. No matter how the structure of the smoking device is designed, the tobacco segment is heated. Due to the plug seal 5, the oxygen content of the tobacco segment will decrease during the heating process, which can create an oxygen-deficient environment for the cigarette. At this time, even if the heating temperature is increased, combustion will not occur. Therefore, the heating temperature can be increased to fully release the tobacco aroma components and increase the smoke volume; and because the round piece containing the flavoring material is used for plug sealing, there will be no situation where tobacco residues fall and pollute the smoking device; in addition, the smoke extraction section 2 has an axial central cavity 21 and a breathable tube wall 22. During the suction process, the outside air enters from the breathable tube wall 22, and mixes with the smoke generated by the heating of the tobacco segment 1 in the central cavity 21 to form mainstream smoke for people to smoke. At the same time, during the suction process, the outside air enters from the breathable tube wall 22, and the air flow rate of the breathable tube wall 22 is high and the pressure is low, which has an extraction effect on the smoke of the tobacco segment 1. In addition, the outside air also has a cooling effect on the smoke; at the same time, since the seal 5 of the plug contains fragrance materials such as rose essence, when the smoking device is heated, the seal 5 releases fragrance and mixes with the smoke for the smoker to inhale, thereby improving the smoker's experience; the closed heating cigarette with a plug of the present invention also has the following effects: the smoke extraction section 2 has an axial central cavity 21 and a breathable tube wall 22, and the tube wall 22 has a certain air permeability. When smoking the cigarette, it does not affect the inflow of outside air; when not inhaling, the smoke will not escape through the tube wall 22, thereby effectively reducing the loss of smoke.

[0036] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
