Description

Technical Field

[0001] The utility model relates to the technical field of heat-not-burn cigarettes, in particular to a particle-type aerosol generating product with hollow ends. Background Art

[0002] As consumers prioritize health and demand a personalized experience with cigarettes, the tobacco industry is continuously responding to these evolving needs by developing a variety of smoking products with reduced tar content and harm reduction. Heat-treated cigarettes, by contrast, differ from traditional cigarettes in their heating method, enabling them to satisfy consumers' sensory needs while providing a healthier smoking experience.

[0003] Currently, tobacco flavoring methods typically involve adding a flavoring gel layer to the support section or adding popping beads to the filter section. A problem with flavoring in the support section is that the aroma decays significantly during the baking process, resulting in poor consistency in aroma quality. Often, the aroma is strong in the early stages of the draw, but almost no flavoring effect in the later stages. Therefore, researchers have also sought methods for sustained-release flavoring in the support section. However, adding popping beads to the acetate tow filter section presents a problem. Because the acetate tow filter section is located at the end, the popping beads must be carefully positioned to ensure they do not protrude from the downstream end face of the acetate tow filter section (the end face facing the lip end). Any exposure of the popping beads on the acetate tow filter section will result in a defective product. Furthermore, even if the popping beads are not exposed, but only near the end face of the acetate tow filter section, there is still a risk of the flavoring substances inside the popping beads leaking out if the consumer pinches them. This requires that the popping bead addition process must strictly control their placement within the acetate tow filter section.

[0004] Furthermore, existing aerosol-generating products typically utilize a solid acetate tow rod at the lip end, which presents the following issues: 1. High smoke temperatures can cause lip burns. As the filter element of the cigarette, the acetate tow rod is located close to the aerosol-generating matrix (i.e., the tobacco segment) and has a significant filtering effect. This can result in relatively high smoke temperatures after passing through the filter. Furthermore, when smoke passes through the solid acetate tow rod, it resides for a long time within the rod, retaining some heat. This increases the smoke temperature near the lip end, increasing the risk of lip burns. 2. Consumers have safety concerns regarding direct lip contact with acetate tow. Acetate is a man-made fiber widely used in cigarette filter production. Although it undergoes special processing to meet food safety and hygiene standards, consumers may still have safety concerns regarding direct lip contact with this material. In particular, if the acetate tow rod has tiny fibers or burrs on its surface, it may increase irritation or discomfort to the lip skin.

[0005] On the other hand, existing aerosol-generating products are usually four-component structures, including an aerosol-generating matrix segment, a support segment, a cooling segment, and a filter segment. Therefore, the current corresponding production settings are all four-component composite equipment, which cannot be used to prepare five-component structure aerosol-generating products.

[0006] Therefore, how to ensure good consistency before and after flavoring, reduce the process difficulty of adding flavoring beads to the acetate fiber tow filter segment, avoid the problem of filter tips burning the mouth, and reduce consumers' safety concerns about their lips touching the filter tips are issues that people urgently want to solve.

[0007] In order to solve the above problems, the present utility model is proposed. Utility Model Content

[0008] The first aspect of the present invention provides a granular aerosol-generating product with a hollow end, comprising an outer wrapping paper 1, and an aerosol-generating matrix 2, a blocking member 3, a composite cooling filter 4, and an end hollow member 5 located within the outer wrapping paper 1;

[0009] The composite cooling filter element 4 includes a hollow cooling element 41 and a filter element 42. The hollow cooling element 41 and the filter element 42 are wrapped with a molding paper 43. The outer wrapping paper 1 outside the composite cooling filter element 4 and the end hollow element 5 is wrapped with a tipping paper 6.

[0010] The aerosol generating substrate 2 has a hollow tube 21 on the outside;

[0011] The filter element 42 contains fragrance-enhancing bursting beads 421 .

[0012] Preferably, the center point of the flavoring bead 421 is located on the side of the central axis of the filter element 42 close to the hollow cooling element 41. In other words, the flavoring bead 421 is located on the side of the flavoring bead 421 close to the hollow cooling element 41.

[0013] Preferably, the hollow cooling element 41 has a vent 411 that penetrates the tipping paper 6, the outer wrapping paper 1, the shaping paper 43, and the wall of the hollow cooling element 41. External air enters the hollow interior of the hollow cooling element 41 through the vent 411 and merges with the smoke.

[0014] The hollow cooling element 41 is a hollow acetate fiber bundle tube, a hollow paper tube or a hollow non-woven fabric tube, and the wall thickness of the hollow cooling element 41 is 0.2-1.2 mm.

[0015] Preferably, the end hollow part 5 is a hollow acetate fiber bundle tube, a hollow paper tube or a hollow non-woven fabric tube, and the wall thickness of the end hollow part 5 is 0.5-1.5 mm.

[0016] Preferably, the axial length of the end hollow part 5 is one to two times the diameter of the end hollow part 5 .

[0017] Preferably, the blocking member 3 is a composite member having a grooved corrugated structure, which includes a tube wall 31 and a tube cavity 32. The tube wall 31 is a grooved corrugated structure, which includes an outer layer 311, an inner layer 312, and a grooved corrugated layer 313 located therebetween. The outer layer 311 defines the outer surface of the blocking member 3, and the inner layer 312 defines the tube cavity 32.

[0018] The tube cavity 32 has a gathering sheet rod 321 in it.

[0019] The structure of the blocking member 3 depends on the form of the aerosol-generating substrate 2. In the present invention, when the aerosol-generating substrate 2 is bulk smoke-generating particles, the blocking member 3 serves not only to support and provide an airflow channel but also to block the smoke-generating particles. Therefore, the blocking member 3 can be a composite member having a grooved corrugated structure. Of course, the blocking member structure provided in the present invention is merely a preferred embodiment; any blocking structure known in the art that can block bulk smoke-generating material and allow smoke to pass through is applicable.

[0020] The gathered sheet rod 321 is formed by gathering sheet materials, wherein the sheet materials include polymer materials, cellulose acetate, paper or non-woven fabrics, and the polymer materials include polylactic acid and polycarbonate;

[0021] The outer layer 311 is selected from paper; the inner layer 312 is selected from tow materials or sheets, the tow materials include acetate fiber tows and polylactic acid tows, and the sheets include paper, reconstituted tobacco leaves or polymer material sheets; the grooved corrugated layer 313 is selected from paper or non-woven fabrics with a grooved structure. In the actual selection process, if a wrinkled sheet is required, non-woven fabrics are preferred, and if a smooth sheet is required, paper is preferred. In addition, it is preferred that the grooved corrugated layer sheet be pre-pressed to form groove folds, and then wrapped with the outer layer 211 and the inner layer 212 to form a tube wall with a grooved corrugated structure. When preparing the gathering sheet rod 221 in the corresponding tube cavity, the sheet material is also pre-pressed to form an indentation first, and then gathered, so as to facilitate the gathering process.

[0022] The cross-sectional shape of the grooves in the grooved corrugated layer 313 is “U”-shaped or “V”-shaped.

[0023] Preferably, the sealing member 3 has a fragrance enhancing component therein.

[0024] Preferably, the aroma and flavor characteristics of the aroma enhancing component in the blocking member 3 and the aroma enhancing bursting beads 421 in the filtering member 42 are inconsistent.

[0025] Preferably, a flavoring material layer is provided on the grooved corrugated layer 313 and / or the gathered sheet rod 321. The flavoring material layer serves as the flavoring component. The flavoring material layer can be selected from commonly used flavors and fragrances, such as natural incense raw materials and tobacco extract. To increase smoke production, the flavoring material layer can also include a smoking agent selected from propylene glycol and glycerol.

[0026] Whether a fragrance component is provided in the blocking member 3 and the provision of the fragrance material layer depends on the actual situation. That is to say, the fragrance bursting beads 421 may be provided only in the filter member 42, and the blocking member 3 does not have the fragrance adding function. Of course, when fragrance is added in the blocking member 3, the location and method of fragrance addition can be very flexible. The fragrance material layer may be provided only on the grooved corrugated layer 313 or the gathered sheet rod 321, or may be provided on both the grooved corrugated layer 313 and the gathered sheet rod 321. The provided fragrance material layer may be a fragrance gel layer or a fragrance gel layer with a porous adsorption material (such as activated carbon). The porous adsorption material may adsorb more fragrance substances and increase the fragrance carrying capacity. Furthermore, the fragrance substances are adsorbed into the porous material, and when released by heat, they may also be slowly released, thereby achieving a slow-release fragrance effect.

[0027] Preferably, the aerosol-generating substrate 2 is in the form of scattered particles.

[0028] The second aspect of the present invention provides a method for preparing the particulate aerosol-generating product with hollow ends according to the first aspect of the present invention, comprising the following steps:

[0029] Step 1: Preparation of mouth sticks:

[0030] First, the hollow cooling element 41 and the filter element 42 are compounded using the molding paper 43 to obtain the compound cooling filter element 4;

[0031] Then, the outer wrapping paper 1 is used to combine the empty pipe 21, the blocking member 3, the composite cooling filter 4 and the end hollow member 5 to obtain a nozzle rod.

[0032] Step 2: Wrap the tipping paper 6;

[0033] The tipping paper 6 is wrapped around the outer wrapping paper 1 outside the composite cooling filter element 4 and the end hollow element 5;

[0034] Step 3: Filling the aerosol generating matrix 2:

[0035] Place the nozzle rod in a vertical position, with the empty tube 21 facing vertically upward, and fill the aerosol generating substrate 2 into the empty tube 21 by filling;

[0036] Step 4: Seal the distal lip end of the aerosol generating substrate 2:

[0037] The end of the aerosol-generating substrate 2 distal from the sealing member 3 is sealed; this sealing may be achieved by placing a sealing paper on the end. The distal lip end of the aerosol-generating substrate 2 refers to the end of the aerosol-generating product distal from the consumer's lips during inhalation, i.e., the end of the aerosol-generating substrate 2 distal from the sealing member 3.

[0038] Preferably, in step 1, the nozzle rod strip can be cut into multiple nozzle rods, and the multiple nozzle rods are connected through the end hollow parts 5 and / or the hollow pipe parts 21.

[0039] Preferably, there is a cutting step before step 3, in which the nozzle bar strip is cut into a plurality of nozzle bars at the connected end hollow parts 5 and / or the connected empty tube parts 21. More preferably, the cutting is carried out at the end hollow parts 5.

[0040] That is, the nozzle bar strip in step one can be a single nozzle bar, i.e., the outer wrapping paper 1 contains a plugging member 3, a composite cooling filter 4, an end hollow member 5, and an empty tube 21. Of course, the nozzle bar strip in step one can be cut into multiple nozzle bars, i.e., the outer wrapping paper 1 contains multiple plugging members 3, a composite cooling filter 4, an end hollow member 5, and an empty tube 21, and the multiple nozzle bars are connected by the end hollow member 5 and / or the empty tube 21, with the connection having an axial length twice that of the end hollow member 5 or the empty tube 21. In this case, in step two, it is necessary to first cut the nozzle bar strip into multiple nozzle bars. That is, the axial length of the end hollow member 5 and / or the empty tube 21 at the connection is twice the axial length of the end hollow member 5 and / or the empty tube 21 in the single nozzle bar. This ensures that each nozzle bar has a complete end hollow member 5 and an empty tube 21 after cutting.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. The filter element of the present invention has fragrance-enhancing beads inside. Since a hollow end part is provided downstream of the filter element, the positioning requirements for the fragrance-enhancing beads when applying the fragrance-enhancing beads inside the filter element are reduced. Even if the fragrance-enhancing beads are close to the downstream end face of the acetate fiber tow filter section (the end face facing the lip end), or even exposed from the downstream end face of the acetate fiber tow filter section, due to the presence of the hollow end part, they will not flow out after being pinched, and the fragrance-enhancing substances in the hollow end part can also play a role in flavoring the smoke when the smoke passes through. The utility model provides a hollow end part downstream of the filter element, which reduces the process difficulty of adding the fragrance-enhancing beads inside the filter element.

[0043] 2. In the present invention, a flavoring component is provided in the blocking member, and flavoring beads are added to the filter member, wherein the flavoring beads in the filter member play the role of supplementing the aroma of the flavoring component in the blocking member and changing the flavor type in the middle and late stages of smoking. Specifically, the blocking member adds flavor to the smoke in the early stage of smoking. When the consumer feels that the aroma is not supplemented enough, the beads can be manually pinched to break, thereby adding flavor to the smoke in the latter half, playing the role of aroma supplement in the latter half. Furthermore, the aroma and flavor characteristics of the flavoring component in the blocking member and the flavoring beads in the filter member may be inconsistent, thereby playing the role of changing the style characteristics before and after smoking. For example, the flavor characteristic of the flavoring component in the blocking member is fruity, while the flavor characteristic of the flavoring beads in the filter member is chocolate. In this way, when the consumer feels that the fruity flavor is not obvious during smoking, he or she can manually pinch the flavoring beads to change to chocolate flavor in the latter half of smoking.

[0044] 3. The utility model sets an end hollow part downstream of the filter element. The end hollow part extends the distance from the aerosol generating matrix section to the mouth end, so the temperature of the outer surface of the end hollow part is lower than the surface of the filter element, thereby avoiding the problem of the mouth end surface of the aerosol generating product being hot.

[0045] 4. The hollow end member of the present invention has an internal airflow channel that minimizes smoke retention. Consequently, smoke stays in the hollow end member for a short time, preventing heat transfer from the smoke to the exterior surface, further preventing the mouthpiece from burning. Furthermore, because the hollow end member minimizes smoke retention, placing the hollow end member downstream of the filter element does not significantly increase draw resistance.

[0046] 5. The hollow end part of the utility model is a hollow acetate fiber bundle tube, a hollow paper tube or a hollow non-woven fabric tube. Since it is hollow inside, the material area in contact with the consumer's mouth is reduced, thereby alleviating the consumer's safety concerns.

[0047] 6. In terms of preparation method, the present invention first forms all units except the aerosol-generating particle segment by rolling and compounding. During compounding, a cavity for filling the aerosol-generating material is reserved. After compounding, the unit is cut as needed. The cut nozzle rod with the empty tube 21 is then placed vertically, and the empty tube 21 is then filled with the aerosol-generating material. The present invention uses a method of compounding first and then filling to prepare aerosol-generating products. Multiple nozzle rods can be compounded simultaneously, and then the aerosol-generating material is filled after cutting. Because all units except the aerosol-generating material are compounded, the efficiency is greatly improved compared to filling each unit individually. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] Example 1

[0062] like Figure 1 As shown, this embodiment provides a granular aerosol-generating product with a hollow end, which includes an outer wrapping paper 1, and an aerosol-generating matrix 2, a blocking member 3, a composite cooling filter 4, and an end hollow member 5 located within the outer wrapping paper 1;

[0063] The composite cooling filter element 4 includes a hollow cooling element 41 and a filter element 42. The hollow cooling element 41 and the filter element 42 are wrapped with a molding paper 43. The outer wrapping paper 1 outside the composite cooling filter element 4 and the end hollow element 5 is wrapped with a tipping paper 6.

[0064] The aerosol generating substrate 2 has a hollow tube 21 on the outside;

[0065] The filter element 42 contains fragrance-enhancing bursting beads 421 .

[0066] The center point of the flavoring bead 421 is located on the side of the central axis of the filter element 42 close to the hollow cooling element 41. In other words, the flavoring bead 421 is located on the side of the flavoring bead 421 close to the hollow cooling element 41.

[0067] In this embodiment, the axial length of the filter element is 8 mm, and the diameter of the bursting bead is 2.5 mm. The center point of the bursting bead is located on the side of the central axis of the filter element 42 close to the hollow cooling element 41, and is 1.0 mm away from the center point of the central axis of the filter element 42.

[0068] The hollow cooling element 41 has a vent 411 that penetrates the tipping paper 6, the outer wrapping paper 1, the shaping paper 43, and the wall of the hollow cooling element 41. External air enters the hollow interior of the hollow cooling element 41 through the vent 411 and merges with the smoke.

[0069] The hollow cooling element 41 is a hollow acetate fiber bundle tube, and the wall thickness of the hollow cooling element 41 is 1.0 mm.

[0070] The end hollow part 5 is a hollow acetate fiber bundle tube, and the wall thickness of the end hollow part 5 is 1.0 mm.

[0071] The axial length of the end hollow part 5 is 1.5 times the diameter of the end hollow part 5 .

[0072] The blocking member 3 is a composite member having a grooved corrugated structure, comprising a tube wall 31 and a tube cavity 32. The tube wall 31 is a grooved corrugated structure, comprising an outer layer 311, an inner layer 312, and a grooved corrugated layer 313 located therebetween. The outer layer 311 defines the outer surface of the blocking member 3, and the inner layer 312 defines the tube cavity 32.

[0073] The tube cavity 32 has a gathering sheet rod 321 in it.

[0074] The gathered sheet rod 321 is formed by gathering sheet materials, and the sheet material is polylactic acid;

[0075] The outer layer 311 is selected from paper; the inner layer 312 is selected from paper; and the grooved corrugated layer 313 is selected from non-woven fabric with a groove structure.

[0076] The cross-sectional shape of the grooves in the grooved corrugated layer 313 is “V”-shaped.

[0077] The aerosol-generating substrate 2 is in the form of scattered particles.

[0078] The method for preparing the aerosol-generating particulate product with hollow ends comprises the following steps:

[0079] Step 1: Preparation of mouth sticks:

[0080] First, the hollow cooling element 41 and the filter element 42 are compounded using the molding paper 43 to obtain the compound cooling filter element 4;

[0081] Then, the outer wrapping paper 1 is used to combine the empty pipe 21, the blocking member 3, the composite cooling filter 4 and the end hollow member 5 to obtain a nozzle rod.

[0082] Step 2: Wrap with tipping paper 6;

[0083] The outer wrapping paper 1 on the outside of the composite cooling filter element 4 and the end hollow element 5 is wrapped with a tipping paper 6;

[0084] Step 3: Filling of aerosol generating matrix 2:

[0085] Place the nozzle rod in a vertical position with the hollow tube 21 facing upwards, and fill the aerosol generating matrix 2 into the hollow tube 21 by filling;

[0086] Step 4: Seal the aerosol generating matrix 2:

[0087] The end of the aerosol generating substrate 2 away from the blocking member 3 is sealed; the sealing can be in the form of providing sealing paper at the end.

[0088] In step 1, the nozzle rod strip can be cut into multiple nozzle rods, and the multiple nozzle rods are connected through the end hollow parts 5.

[0089] There is also a cutting step before step three, which is to cut at the connected end hollow parts 5 to cut the nozzle rod strip into multiple nozzle rods.

[0090] like Figure 2 As shown, the nozzle rod strip in step one can be cut into two nozzle rods, that is, the outer wrapping paper 1 contains two sealing parts 3, a composite cooling filter 4, an end hollow part 5 and an empty tube part 21, and the two nozzle rods are connected by the end hollow part 5, and the connection has twice the axial length of the end hollow part 5. In this case, when performing step two, it is necessary to first cut the nozzle rod strip into two nozzle rods.

[0091] Example 2

[0092] The difference between the granular aerosol generating product with hollow ends in this embodiment and that in embodiment 1 is that the sealing member 3 has a fragrance enhancing component therein.

[0093] The aroma and flavor characteristics of the aroma enhancing component in the blocking member 3 and the aroma enhancing bursting beads 421 in the filter member 42 are inconsistent, which makes it convenient for consumers to change their aroma style midway.

[0094] The grooved corrugated layer 313 and the gathered sheet rod 321 are provided with a fragrance material layer, which serves as the fragrance enhancing component. Similar to this embodiment, a fragrance material layer can also be provided on one of the grooved corrugated layer 313 and the gathered sheet rod 321.
