Description

The claims of the present invention relate to the technical field of producing heat-not-burn tobacco, and specifically to tobacco sticks of heat-not-burn tobacco with a low cut-off.

As consumers become more focused on health issues and consumer demand for personalized experiences of tobacco products increases, the tobacco industry continues to respond to consumer demand upgrades, reducing tar and harm. We have developed various types of tobacco sticks. Heat-not-burn tobacco is different from traditional tobacco products in that it heats the tobacco, which can provide a healthier inhalation experience while meeting the consumer's sensory needs for tobacco products.

し、燃焼ガス及び空気の気流チャネルが塞がれて、エアロゾル量が不足すること、
２．燃焼ガスと支持セグメントのチューブ壁との接触面積が限られており、効果的な降温を実現できないこと、
３．燃焼ガス及び空気は、支持セグメント内に滞留する時間が短く、支持セグメントをただちに高速で通過して降温セグメントに入るので、十分な混合が達成できないこと。
そのため、燃焼ガスの更なる降温を実現するために、現在主に行われているのは、降温セグメントの降温材料に対して改良を行うこと、又は直接的に降温材料の使用量を増やすことである。しかし、降温材料の多くは相変化材料であり、何回か吸引した後には相変化材料が収縮陥没して気流チャネルを塞ぎ、吸引抵抗が大幅に上昇して、吸引体験に影響を与える。 Existing heat-not-burn tobacco tobacco sticks mainly include a smoke core material segment, a support segment, a temperature reduction segment, and a filter chip segment, and the support segment serves to support the tobacco stick, but not only that. More importantly, it collects the combustion gas and works with the cooling segment to cool the combustion gas. In the prior art, the online laser perforation method is used to make through holes in the tube wall of the support segment and the paper pattern and bonding paper that wrap the tube wall to form ventilation holes, thereby allowing outside air to enter the inside of the support segment and burn. Mix with gas. This increases the amount of aerosol and effectively lowers the temperature of the combustion gas, but the effect of lowering the temperature on the combustion gas and the effect of mixing the air with the combustion gas remain poor. There are three reasons for this.
1. 1. The radial bearing capacity of the tube wall of the support segment is insufficient, and the tube wall receives an external force and contracts and collapses toward the center of the tube cavity.

However, the airflow channels of combustion gas and air are blocked, and the amount of aerosol is insufficient.
2. The contact area between the combustion gas and the tube wall of the support segment is limited, and effective temperature reduction cannot be achieved.
3. 3. Combustion gas and air stay in the support segment for a short period of time and immediately pass through the support segment at high speed to enter the cooling segment, so sufficient mixing cannot be achieved.
Therefore, in order to realize further temperature reduction of combustion gas, the main thing currently being done is to improve the temperature reduction material in the temperature reduction segment or directly increase the amount of the temperature reduction material used. be. However, most of the temperature-lowering materials are phase-changing materials, and after several suctions, the phase-changing materials contract and sink to block the airflow channel, and the suction resistance increases significantly, which affects the suction experience.

In another aspect, online laser perforation is used to perforate the support segment of the tobacco stick, which has the following problems:
1. 1. The process of online laser perforation has relatively high demands on the material and thickness of the tube wall of the support segment. First, the material of the tube wall of the support segment must not collapse in the process of online laser perforation, but the tube wall must not be particularly thick enough to prevent through-holes during online laser perforation.
2. The online laser drilling process also has very high demands on laser power, and if the laser drilling equipment cannot drill through holes in the tube wall of the support segment, the production of heat-not-burn tobacco tobacco sticks will fail. The problem of becoming too hot and the problem of the combustion gas being too hot can occur.
3. 3. Currently, vents are formed by drilling through holes in the support segment and the paper pattern and bonding paper that wraps the support segment, and the outside air enters the inside of the support segment directly through the vents, so that the vents introduce air. The speed of operation is high, the contact area between the introduced air and the combustion gas is limited, and the mixing becomes non-uniform. Although the amount of combustion gas sucked into the consumer's mouth increases, the concentration of combustion gas is low, it is clear that a large amount of air is mixed in the combustion gas, and the smoking quality is seriously deteriorated.
4. In all current online laser perforation methods, perforation is performed at a distance of 14 to 15 mm or 18 to 19 mm from the tobacco segment of the support segment, so that the position of the vent is fixed.

Therefore, the support segment not only plays a relatively good role in supporting the entire tobacco stick, but also needs to be considered for its role in lowering the temperature of the combustion gas and collecting the combustion gas. In other words, it is required to develop a tobacco stick of a heated non-combustion tobacco, which has an appropriate temperature of combustion gas, a sufficient amount of aerosol, uniform mixing with combustion gas, and high quality of combustion gas. Has been done.

This makes it possible to obtain a support member 23 having a corrugated cross section, and by winding the corrugated first breathable paper material from one side to the other, the cross section has a hollow polygonal shape. It becomes possible to obtain the support member 23.

When one end of the folded and formed support member 23 is rotated in a certain direction and then twisted at an angle of 5 ° to 30 ° in the circumferential direction with respect to the other end, the support member 23 is twisted to the support segment 2. It becomes possible to extend spirally along the axial direction of.

In step (1), a paper material having good support performance is crushed and made porous so that the hot combustion gas and air are sufficiently mixed in the support segment 2 and the problem of shrinkage and depression does not occur. The structure forms a first breathable paper material. All paper materials that have a certain hardness and are easy to fold and mold (for example, ordinary A4 paper, large gram weight molded paper, or kraft paper) have good support performance according to step (1). It can be a paper material.

Preferably, the support member 23 is provided with a fragrance-enhancing material layer 231. A mixed solution of ethanol and polyhydric alcohol is used as a solvent, and the content of polyhydric alcohol in this solvent exceeds 50%. Tobacco extract and tobacco flavoring material are added to the solvent to prepare a saturated solution. The support member 23 is formed by spraying a saturated solution onto the first breathable paper material of the support member 23 formed by folding (that is, the first breathable paper material formed in step (1) described above). A fragrance-enhancing material layer 231 is formed on the layer. 1 to 5 mL of the saturated solution described above is sprayed per 1 gram of the first breathable paper material of the support member 23 formed by folding.

Preferably, the support segment 2 has vents 24 that penetrate the tube wall 21, the paper pattern 5, and the bonding paper 6 along the radial direction of the support segment 2.

In another preferred embodiment, the support segment 2 has a ventilation window 25 that penetrates the tube wall 21 along the radial direction of the support segment 2, and the area surrounding the support segment 2 of the bonding paper 6 has a ventilation hole 26. The area of the ventilation hole 26 is smaller than the area of the ventilation window 25, and the ventilation hole 26 overlaps the ventilation window 25 at least partially.

Preferably, a temperature lowering segment 3 is further provided between the support segment 2 and the filter chip segment 4, and the support segment 2, the temperature lowering segment 3, and the filter chip segment 4 are wrapped with a molding paper to form a mouthpiece. The smoke core material segment 1 and the mouthpiece are joined by a bonding paper, and the length of the support segment 2 is 1/3 to 3/4 of the total length of the mouthpiece.

The tube wall 21 of the support segment 2 is made of a paper material, a non-woven fabric of a polymer material, or an extruded polymer material, and the polymer material is acetate fiber, polylactic acid, polyethylene, polypropylene, modified starch, or polyethylene. Selected from terephthalate. This modified starch is a starch treated with a carboxyl group or a hydroxyl group of a functional group.

When the tube wall of the support segment 2 is selected from the non-woven fabric of the paper material or the polymer material, the ventilation window 25 is opened by first opening the paper material or the non-woven fabric of the polymer material forming the tube wall 21 by a cutting method in advance. It may be formed, and then the support segment 2 is formed by further winding the paper material or the non-woven fabric of the polymer material immediately or by folding it in half and then winding it. When the support segment 2 is made by the polymeric material extrusion method, the ventilation window 25 is formed in the process by which the support segment 2 is extruded from the polymeric material.

The tobacco stick of the heat-not-burn non-combustion tobacco described in the present invention can also be ignited and sucked in the same manner as the conventional tobacco.

The present invention has the following beneficial effects as compared with the prior art.
1. 1. The support segment 2 of the present invention is provided with a support member 23 made of a paper material having a good supporting force. Since the support member 23 can come into contact with the tube wall 21 to provide a radial support force to the tube wall 21, the tube wall receives an external force and contracts and sinks toward the center of the tube cavity 22, resulting in an air flow of combustion gas. The problem of channel blockage and insufficient aerosol volume is avoided.
2. The support segment 2 of the present invention is provided with a support member 23 that divides the tube cavity 22 into a plurality of airflow channels. After the combustion gas enters the temperature lowering element, the support member 23 divides the group of combustion gas into a plurality of courses, so that the contact area between the combustion gas and the support member 23 increases. Along with this, the support member 23 of the present invention is the first air permeable paper material, and the air entering the tube cavity 22 through the ventilation hole 24 or the ventilation window 25 passes through the first breathable paper material and then in the longitudinal direction. Dispersed in each of the channels and completely mixed with the combustion gas in the longitudinal channel, the temperature of the combustion gas drops further.
3. 3. When the total volume of the longitudinal channels in the support segment 2 of the present invention is 50% to 90% of the volume of the tube cavity 22, the flow of combustion gas becomes smooth. That is, by the support segment 2 of the present invention, the combustion gas temperature is suitable for suction by sufficiently mixing the combustion gas and air in the tube cavity 22 without increasing the cutoff of the combustion gas. A heat-not-burn tobacco stick with a sufficient amount of aerosol can be obtained.
4. In a preferred embodiment of the present invention, the support member 23 extends axially along the support segment 2 in a spiral shape, but by adopting this spiral extension method, combustion in the longitudinal channel is performed. Since it is possible to change the flow path of the gas and air, the time for the combustion gas and air to stay in the support member 23 is increased, the combustion gas and air are mixed, and the combustion gas and air are immediately and at high speed. The passage through the support member 23 is avoided, and the temperature of the combustion gas is further lowered.
5. Since the support member 23 of the present invention is a paper material that does not shrink and sink in the process of phase change heat absorption, the phase change material shrinks and sinks after sucking several mouths, blocking the airflow channel, and the suction resistance increases significantly. And avoid affecting the suction experience.
6. In a preferred embodiment of the present invention, a ventilation window 25 is first formed in the tube wall 21 of the support segment 2, and a ventilation hole 26 is formed in advance in the bonding paper 6. After that, a paper pattern 5 in the form of a breathable non-woven fabric is used to wrap the support segment 2 and the filter chip segment 4 to form a mouthpiece, and the bonding paper 6 is used to wrap the smoke core material segment 1 and the mouthpiece to make a cigarette. A stick is formed, in which the ventilation holes 26 of the bonding paper 6 and the ventilation windows 25 of the support segment 2 are partially overlapped with each other. By this method, online laser perforation of the support segment 2 of the tobacco stick and the paper pattern 5 and the wrapping paper 6 wrapping the support segment 2 is avoided, so that the wall material and wall thickness of the tube wall 21 of the support segment 2 are required. As it becomes lower, the demand for laser power in the online laser drilling process also becomes lower, making it even easier to implement in industrialized production processes.
7. In a preferred embodiment of the present invention, there is a breathable paper pattern 5 on the outside of the ventilation window 25 of the support segment 2, followed by a ventilation hole 26 of the bonding paper 6. In the process of sucking the tobacco stick, outside air enters the inside of the support segment 2 through the ventilation holes 26, the breathable paper pattern 5, and the ventilation window 25. The breathable paper pattern 5 functions like a screen door in an existing window. The air that has passed through the ventilation hole 26 does not enter the inside of the support segment 2 directly, but the outside air enters the support segment 2 after passing through the one-layer screen door, so that the air enters the inside of the support segment 2. The rate of entry can be further reduced, which can result in better contact with the combustion gas. Further, the area of the ventilation window 25 of the present invention is larger than that of the ventilation hole 26, and the air that has entered the support segment 2 is more easily diffused and the contact area with the combustion gas is large. Mixing is even better. Therefore, although the amount of combustion gas sucked into the mouth of the consumer increases, the concentration of the combustion gas is low, and a clearly large amount of air is mixed in the combustion gas, and the problem that the smoking quality is seriously deteriorated can be avoided.
8. In a preferred embodiment of the present invention, both the ventilation window 25 and the ventilation hole 26 are formed in advance before the tobacco stick is rolled up, and the ventilation window 25 and the ventilation hole 26 have their positions and shapes. Since it is not limited, it can be formed at any position of the support segment 2. At the same time, the support segment 2 is perforated and the bonding paper 6 is perforated before being rolled, because the support segment 2, the molding paper 5, and the bonding paper 6 are perforated online after the roll is made to make a tobacco stick. However, since the difficulty is obviously low, this method makes it easier and more effective to realize in an industrialized production process.
9. In a preferred embodiment of the present invention, since the incense-enhancing material layer 231 is provided on the support member 23, it is possible to add a scent to the combustion gas while lowering the temperature of the combustion gas.
