Description

An aerosol generating product with a scented support section

Technical Field

The invention relates to the technical field of aerosol generating products, in particular to an aerosol generating product with a scented support section.

Background technique

As consumers pay more attention to health issues and demand more personalized experience in cigarette products, the tobacco industry continues to respond to the upgrading of consumer demand and develop various smoking products with reduced tar and harm. Among them, heat-not-burn cigarettes are different from traditional cigarette products in that their heating method is different, which enables them to meet consumers' sensory needs for cigarette products while providing a healthier smoking experience.

Existing aerosol generating products mainly include a smoking core material section, a supporting section, a cooling section and a filter section, wherein the supporting section not only supports the smoking product, but more importantly gathers the smoke and assists the cooling section in cooling the smoke. The prior art uses an online laser punching method to punch through the tube wall of the support section, the forming paper and the tipping paper that wrap the tube wall to form ventilation holes, so that outside air enters the support section and mixes with the flue gas, thereby increasing the amount of smoke and effectively reducing the flue gas temperature. However, the cooling effect on the flue gas and the mixing effect of air and flue gas are still poor. The reasons are as follows: 1. The radial supporting force of the tube wall of the support section is insufficient. After the tube wall is subjected to external force, it collapses toward the center of the tube cavity, causing the airflow channel of the flue gas and air to be blocked and the amount of smoke to be insufficient; 2. The contact area between the flue gas and the tube wall of the support section is limited, and effective cooling cannot be achieved; 3. The residence time of the flue gas and air in the support section is short, and the flue gas and air directly and quickly pass through the support section into the cooling section, and cannot be fully mixed; 4. The flue gas directly contacts the tube wall of the support section, and because the flue gas that passes through the support section has not been effectively cooled, the flue gas temperature is too high, resulting in the problem that this section of the tube wall is hot. Therefore, in order to further cool the flue gas, the current approach mainly focuses on improving the cooling materials in the cooling section or directly increasing the amount of cooling materials used. However, most cooling materials are phase change materials. After a few puffs, the phase change materials collapse and block the airflow channel, greatly increasing the inhalation resistance and affecting the inhalation experience.

In addition, the existing aerosol-generating products are generally flavored by tobacco materials, filters, and cigarette papers. The flavoring process is difficult, inefficient, and the flavor release is unstable. Existing aerosol-generating products usually place flavored bursting beads in the filter. Consumers manually break the bursting beads before inhaling, so that the flavoring substances inside are released, thereby playing a role in flavoring the aerosol during inhalation. However, the problem is that since the bursting beads have been completely broken before inhalation, the flavoring substances inside are completely released, which results in a strong flavor in the early stage of inhalation, and the aroma is significantly weakened in the later stage of inhalation, with almost no flavoring effect. The disadvantage of carrying fragrance through tobacco materials or cigarette papers is that since many fragrances are highly volatile, these characteristic fragrances are easily lost after the user opens the package, resulting in the last few cigarettes in each pack having no fragrance and poor quality.

In order to solve the above problems, the present invention is proposed.

Summary of the invention

The aerosol generating product of the present invention is applicable to both circumferential aerosol generating product smoking articles and central aerosol generating product smoking articles.

Compared with the prior art, the present invention has the following beneficial effects:

1. The support section 2 of the present invention has an air flow channel 22 and a plurality of flavoring channels 21; the plurality of flavoring channels 21 surround the outside of the air flow channel 22, and the end of the flavoring channel 21 close to the smoking core material section 1 is blocked, while the end close to the breathable hollow section 3 is open, and the flavoring channel 21 has a flavoring capsule 11. That is to say, the air flow channel of the support section 2 is divided into two types, the first type is the air flow channel located in the center, which is used for aerosol circulation, and the second type of air flow channel is the flavoring channel located on the peripheral side, which is blocked on the side close to the smoking core material section 1, that is to say, the aerosol generated by the heating of the smoking core material section 1 cannot enter the flavoring channel. When hot aerosol flows through the air flow channel 22, the bursting beads in the flavoring channel 21 are ruptured by heat, releasing the aroma substance, and flowing along the flavoring channel to the breathable hollow section 3. The advantages of this structure are:

(1) The popping beads do not come into direct contact with the hot aerosol, but transfer heat through the wall of the fragrance adding channel. This ensures that the popping beads will not burst and release all the fragrances instantly due to strong heat, but will slowly release the fragrances due to slow heat, thus achieving a slow release effect.

(2) Since no hot smoke will flow in the aroma channel 21, the aroma channel 21 forms an air insulation layer to prevent the support section pipe wall from directly contacting the smoke and causing the outer surface temperature to be too high and hot to the touch;

(3) The bursting beads in the flavoring channel 21 are ruptured by heat, releasing the flavoring substances, and flow along the flavoring channel to the breathable hollow section 3. Since the breathable hollow section 3 has ventilation holes 31 that radially penetrate the tube wall of the breathable hollow section 3, the outside air enters the breathable hollow section through the ventilation holes. The outside air first contacts the flavor vapor on the side to condense it into small droplets, and then contacts the mainstream smoke in the center. The small flavor droplets can serve as condensation nucleation points to promote the condensation of smoke droplets around the flavor droplets, forming a core-shell structure in which the smoke droplets wrap the flavor droplets, rather than a disordered mixed structure of the flavor droplets and the smoke droplets, so that the user feels that the fragrance is long-lasting.

2. The present invention places the flavoring capsule 11 at the end of the downstream support section 2 of the smoking core material section 1, which is adjacent to one end of the smoking core material section 1, and the capsule wall of the flavoring capsule 11 is selected from materials that can be broken at an ambient temperature of 150-200°C. This means that when not inhaled, due to the protection of the capsule wall, the aroma substances inside the flavoring capsule 11 will not be released, and the flavoring capsule is placed in the flavoring channel 21 of the support section 2. Due to the protection of the tube wall of the support section 2 and the molding paper 5, the loss of aroma substances during long-term placement is further avoided. In addition, the flavoring capsule 11 of the present invention is not like the existing bursting beads, which require consumers to pinch and break to release the internal aroma substances, but is selected from materials that break at an ambient temperature of 80-200°C as the capsule wall. When consumers inhale, the temperature of the cigarette core material section is the highest, at about 120°C. When hot aerosol flows through the air flow channel 22, the bursting beads in the aroma channel 21 are heated and broken, releasing the aroma substances, and flowing along the aroma channel to the air-permeable hollow section 3. The advantages of using the flavoring capsule to rupture when heated are as follows: ① It just takes advantage of the end of the flavoring capsule 11 in the support section 2 that is close to one end of the smoke-generating core material section 1. If it is in other sections, the temperature will not reach the rupture temperature; ② Previously, the bursting beads were mostly added to the acetate filter section. Since the resilience of the support section tube wall is far inferior to that of the acetate, the acetate rebounds after the bursting beads are pinched, and there is almost no deformation. If the bursting beads are pinched through the support section tube wall, the support section will be deformed, which will change the support section structure and airflow channel, affecting the suction effect and bringing a bad consumer experience. The thermal rupture perfectly solves this problem; ③ The thermal rupture of the capsule wall of the flavoring capsule 11 can further reduce the temperature of the smoke.

Furthermore, the reason and advantage of placing the flavoring capsule 11 at the end of the downstream support section 2 of the smoking core material section 1 adjacent to one end of the smoking core material section 1, rather than placing the flavoring capsule 11 inside the smoking core material section 1, is that when the consumer is smoking, the temperature of the cigarette core material section is the highest, about 120°C. If the flavoring capsule 11 is placed in the cigarette core material section and wrapped by the smoking material, the flavoring capsule 11 will be subjected to continuous high temperature during the smoking process, causing the capsule wall of the flavoring capsule 11 to rupture rapidly, and the flavors and spices inside to evaporate rapidly, which will result in a strong flavor in the first few puffs of smoking, but almost no flavoring effect in the next few puffs of smoke. On the other hand, due to the high temperature of the flavoring capsule 11, although the capsule wall is indeed easier to rupture, there are some flavors and spices with lower volatile temperatures inside the flavoring capsule 11, such as menthol, orange oil, rose essential oil, etc., which creates a dilemma that the capsule wall needs a certain temperature to rupture, but the low volatile temperature flavors and spices in the capsule wall will evaporate instantly if the temperature is too high.

The present invention places the flavoring capsule 11 at the end of the downstream support section 2 of the smoking core material section 1, which is adjacent to one end of the smoking core material section 1, and is placed in the flavoring channel of the support section 2. Since this end of the support section 2 is close to the smoking core material section 1, the smoke generated by the smoking core material section 1 still has a relatively high temperature when it just enters the neutral air flow channel, which can reach the degree of rupturing the flavoring capsule 11. However, since the flavoring capsule 11 is in the flavoring channel of the support section 2, the bursting bead does not directly contact the hot aerosol, but transfers heat through the wall of the flavoring channel, so that it can be ensured that the bursting bead will not be instantly exposed to strong heat and burst to release all the fragrances, but slowly releases them under slow heat, thereby achieving the effect of stable and slow release of fragrance.

In combination with the structure of this support section, the present invention punches holes in the breathable hollow section 3 downstream of the support section 2 to form ventilation holes for introducing air, rather than punching holes in the tube wall of the support section 2 to introduce air as in the prior art. The reason and effect of this are: not punching holes in the support section 2 to introduce air can first ensure that the flavoring capsules 11 inside the support section 2 can have sufficient smoke temperature to burst and add fragrance, and after the smoke has been initially cooled and flavored, further introducing air from the breathable hollow section 3 can further cool and gather the smoke.

2. The smokable core material segment 1 of the present invention is wrapped by an impermeable cigarette paper 12. During the storage of cigarettes, the moisture in the smokable material seeps to the outside of the cigarette paper tube, causing yellow spots. Therefore, it is necessary to add a waterproof layer to the inner wall of the cigarette paper tube filled with the smokable material. The waterproof layer can prevent the moisture in the smokable material from seeping to the outside of the cigarette paper tube.

Similarly, smoking agents are added to smoking materials. During long-term storage, the smoking agents in the smoking materials will carry flavors and fragrances to penetrate the outer side of the paper tube, resulting in yellow spots and affecting the appearance of the paper tube. Since the smoking agents are oily, it is necessary to add an oil-proof layer to the inner wall of the cigarette paper tube filled with smoking materials. The oil-proof layer can prevent the smoking agents in the smoking materials from carrying flavors and fragrances to penetrate the outer wall of the paper tube, thus preventing the occurrence of yellow spots.

More importantly, the present invention places a flavoring capsule 11 at the end of the downstream supporting section 2 of the smoking core material section 1, adjacent to one end of the smoking core material section 1, so the shaping paper 5 has an impermeable layer on the side close to the supporting section 2. During the inhalation process, after the capsule wall is broken, the aroma substance inside the flavoring capsule 11 may also penetrate into the tube wall of the supporting section 2, and the impermeable layer can prevent the problem of flavors and fragrances penetrating into the shaping paper.

3. The support section 2 of the present invention has a flavoring channel 21 and a neutral air flow channel 22, wherein the flavoring channel 21 is used for flavoring, and the neutral air flow channel 22 is used for gathering smoke. A portion of the flavoring channel 21 has a flavoring capsule 11 at one end near the smoke-generating core material section 1, and the amount of the flavoring capsule 11 added can be controlled. The neutral air flow channel 22 can be used to gather smoke, reduce the adsorption of smoke, and increase the amount of smoke. On the other hand, the flavoring channel 21 is dispersed outside the neutral air flow channel 22, and the flavoring is more uniform.

4. The aerosol generating product of the present invention further comprises a support section 2 of a hollow structure, wherein the support section not only supports the aerosol generating product, but more importantly gathers smoke and helps to reduce the temperature of the smoke, thereby solving the problem of high temperature smoke entering the smoker's oral cavity and burning the mouth.

5. The air-permeable hollow section 3 of the present invention has ventilation holes 31. When the shape and size of the ventilation holes 31 of the present invention and the holes punched in the supporting section of the prior art are consistent, the ventilation holes 31 of the present invention are closer to the mouth of the smoker, so the suction at the ventilation holes 31 is significantly greater than the suction at the holes punched in the supporting section of the prior art. Therefore, the ventilation effect of the ventilation holes 31 of the present invention is better, and the amount of ambient air introduced is larger, which is more conducive to reducing the temperature of the smoke. At the same time, the cigarette supporting section 2 of the present invention has a cavity, and the air-permeable hollow section 3 also has a cavity, so the introduced air can better contact and mix with the smoke, further reducing the temperature of the smoke. The present invention punches holes in the cooling section instead of the supporting section, so as to further utilize the change in suction to increase the air intake and reduce the smoke temperature.

Example 3

Aerosol generating product sample 1 and aerosol generating product sample 2 were smoked with matching heat-not-burn cigarette smoking utensils under the same conditions. During the smoking process, the temperature of the smoke-generating core material segment 1 of the aerosol generating product was about 200°C. The aerosol generating product was sensory evaluated by multiple sensory evaluation personnel, mainly examining six indicators: smoke volume, aroma and fragrance, strength, coordination, irritation, and taste; the scoring values of the six quality inspection indicators were: smoke volume 0-10 points, aroma and fragrance 0-30 points, strength 0-10 points, coordination 0-10 points, irritation 0-15 points, and taste 0-25 points, wherein the total score of the six evaluation indicators was 100 points, and the higher the scores of the five evaluation indicators of smoke volume, aroma and fragrance, strength, coordination, and taste, the stronger the feeling of the evaluation indicator during the smoking process, the higher the score of the irritation evaluation index, the less obvious the feeling of the evaluation index during the smoking process, and the higher the total score of the six evaluation indicators, the better the smoking feeling of the aerosol generating product. Among them, the sensory evaluation scores of aerosol generating product sample 1 and aerosol generating product sample 2 are shown in Table 1.

Mainly carried out according to Q/YNZY.J07.022.

Table 1 Sensory evaluation scores of different aerosol-generating product samples during inhalation

As can be seen from Table 1, aerosol generating product sample 1 and aerosol generating product sample 2 have different degrees of increase in aroma and fragrance, irritation improvement, taste, etc., and aerosol generating product sample 1 and aerosol generating product sample 2 generate sufficient amount of smoke during the heating process to meet the needs of smokers.

In addition, the smoke temperature of the aerosol-generating product sample 1 entering the smoker's mouth is 39.2°C, while the smoke temperature of the aerosol-generating product sample 2 entering the smoker's mouth is 38.9°C. This is because the air-permeable hollow section 3 of the present invention has a ventilation hole 31. When the shape and size of the ventilation hole 31 of the present invention and the hole punched on the support section of the prior art are consistent, the ventilation hole 31 of the present invention is closer to the mouth end of the smoker, so the suction force at the ventilation hole 31 is significantly greater than the suction force at the hole punched on the support section of the prior art. Therefore, the ventilation effect of the ventilation hole 31 of the present invention is better, and the amount of ambient air introduced is larger, which is more conducive to reducing the smoke temperature. At the same time, the cigarette support section 2 of the present invention has a cavity, and the air-permeable hollow section 3 also has a cavity, so the introduced air can better contact and mix with the smoke, further reducing the smoke temperature.

In addition, since there is no hot smoke flowing in the aroma channel 21, the aroma channel 21 forms an air heat insulation layer. The sensory evaluators clearly feel that the outer surface temperature of the support section of the product of the present invention is lower than that of the existing aerosol generating products during the smoking process, and there is no problem of being hot. At the same time, whether in the early, middle or late stages of smoking, the aroma evaluation scores given by the sensory evaluators are basically the same, and there is no problem of strong aroma in the early stage of smoking and weak aroma in the late stage.
