Description

[Technical field]

[0001] The present invention relates to the technical field of non-combustion heated tobacco products, and in particular to a cartridge for non-combustion heated tobacco products and a manufacturing method thereof. [Background technology]

[0002] Non-combustion heated tobacco products are novel products that combine a heater and a tobacco cartridge, and use non-tobacco smoke-producing materials to produce smoke similar to that of a traditional cigarette when heated.

[0003] Generally, a cartridge for non-combustion heated tobacco products includes at least three sections, a smoke generating section, a support member, and a transition stage, and the support member is usually a columnar separator. For example, Patent Document 1 discloses a non-combustion heated tobacco product including a first support unit, a smoke generating unit, a second support unit, a cooling unit, and a filter unit, which are arranged in order, the first support unit includes a support column having a corrugated body therein, and a first covering layer covering the support column, the first covering layer covering the support column, and the support column has a space between adjacent corrugated bodies. Such a support column is inconvenient to manufacture because it uses a covering layer method, and although such a support column is suitable for a sheet or filament-shaped smoke generating material, it is prone to clogging when a granular smoke generating material is used.

[0010] Preferably, both ends of the inner tube are sealed with a highly permeable paper film, and the end of the outer tube that is filled with the smoke-producing agent is packaged with a highly permeable paper film, and the outer tube is the outermost part of the cigarette cartridge.

[0011] Preferably, the outer tube and the inner tube are made of the same hard cardboard material, and are thermally conductive, so as to quickly lower the heating temperature of the smoke generating material, which is granular.

[0012] The method for producing the above-described non-combustion heating tobacco cartridge includes: S01: arranging a plurality of first tubes in a first mold tray having a lattice arrangement, each lattice having a through hole for receiving the first tube; S02: a step of clamping the bottom ends of the first tubes when the first tubes are placed in a first mold tray and applying adhesive to the top ends of each of the first tubes; S03: A process of covering the first tube with a roll of highly permeable paper and attaching it to the top end of each first tube with an adhesive; S04: A process of cutting the highly permeable paper at the top end of each first tube into the shape of a sealing film using a die cutter to form an inner tube having a highly permeable paper sealing portion; S05: arranging the second tubes in a second mold tray in an orderly manner; filling one end of the second tubes with a smoke generating material and turning the other end upward; making the second tubes a prefabricated body of an outer tube; and the second mold tray has a lattice arrangement in the same number and arrangement as the first mold tray; S06: A step of aligning a first mold tray and a second mold tray, placing the end of the inner tube having the highly permeable paper sealing portion downward, and pushing each inner tube into the outer tube via a push pin mold plate, inserting the entire inner tube into the outer tube, and then filling the filter body to obtain the non-combustion heated tobacco cartridge. It includes.

Therefore, the inner tube of the tobacco cartridge can not only provide a support function, but also has good air permeability for sending smoke to the filter body. In addition, for granular smoke generating bodies, the highly permeable paper film can completely block the granules, but the conventional support pole with air holes cannot effectively block the granules, and the granules clog the air holes. Furthermore, through such a structural method of the inner tube, the smoke can be uniformly and quickly sent to the filter body through the hollow cavity, allowing the smoker to smoke, and giving the smoker the same comfortable experience as a real cigarette, improving the user experience. In addition, the method for manufacturing cigarette cartridges involves the processes of applying adhesive to the tube body, covering it with film, cutting, and then fitting the inner and outer tubes together in a nested manner. In this method, both of the two tube bodies are arranged in a lattice, and the method for pushing the inner tube in also uses a push-pin array, which makes the operation easy. The entire process adopts array-type batch production, which on the one hand can make the overall quality uniform, and on the other hand can greatly improve production efficiency, reduce production costs, and enhance the competitiveness of the product, and has the potential for wide applications.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] The present invention will now be described in detail with reference to specific embodiments and the accompanying drawings.

[0019] 1 and 2 show a non-combustion heated tobacco cartridge 100 and an inner tube 20 provided by an embodiment of the present invention, the tobacco cartridge 100 comprises an outer tube 10, and a filter body 13 and a smoke generating body 12 respectively filled at both ends of the outer tube 10. The inner tube 20 is mounted in the outer tube 10, and at least one end of the inner tube 20 is sealed with a film 25 made of highly permeable paper 25a. The inner tube 20 is disposed between the filter body 13 and the smoke generating body 12. The end of the film 25 made of highly permeable paper 25a of the inner tube 20 having a sealed portion is adjacent to the smoke generating body 12, and the film 25 made of highly permeable paper 25a can transmit the smoke generated from the smoke generating body 12 through the cavity of the inner tube 20 to the filter body 13.

[0020] Specifically, both ends of the inner tube 20 contact the filter body 13 and the smoke generating body 12, respectively, and the filter body 13 and the smoke generating body 12 are fixed at predetermined positions on both ends of the outer tube 10. In this embodiment, the smoke generating body 12 is granular, and a granular smoke generating material, preferably a nicotine-free smoke generating material, is used.

[0021] Preferably, the inner tube body 20, the filter body 13 and the smoke generating body 12 are connected to each other along the axial direction, and the sum of the lengths of the inner tube body 20, the filter body 13 and the smoke generating body 12 is basically the same as the overall length of the outer tube body 10. This reliably stabilizes the internal structure of the outer tube body 10, making it sturdy and durable. More preferably, the outer diameter of the inner tube body 20 is smaller than the inner diameter of the outer tube body, and the difference in dimensions is such that the inner tube body 20 moves when pressed by an external force, but can stop arbitrarily without slipping when there is no external force, and is preferably 0.1 mm to 0.2 mm.

[0022] Furthermore, both ends of the inner tube 20 are sealed with a film 25 made of highly permeable paper 25a, and the end of the outer tube 10 filled with the smoke generating agent 12 is packaged with a film 25 made of highly permeable paper 25a, and the outer tube 10 is the outermost part of the cigarette cartridge. Therefore, no exterior paper is required on the outer surface of the outer tube 10. Since the sealing process of the present invention is mature, sealing of both ends can be easily achieved, and the same process is used to seal the outer tube 10, and the manufacturing process is simple.

[0023] Specifically, the outer tube 10 and the inner tube 20 are hard cardboard tubes of the same material, and are thermally conductive tubes, so that the heating temperature of the smoke generating body 12 can be quickly lowered, and the smoke generating body 12 is granular. In this embodiment, the size of the inner tube 20 is preferably 12 to 18 mm, and more preferably 12 to 15 mm. The inside of the inner tube 20 is a hollow cavity 26 without any filling, which allows smooth air flow.

[0024] Another aspect of the embodiment of the present invention also provides a method for manufacturing the above-described non-combustion heated tobacco cartridge, the method comprising the steps of:

[0025] S01: A step of arranging a plurality of first tubes 20a in an orderly manner on a first mold tray 31 having a lattice arrangement, each lattice having a through hole for receiving the first tubes 20a. 3 shows the structure of a first mold tray 31 having a plurality of through holes 35 arranged in an array. Although an array of 10×10 holes is shown in the figure, this can be provided as needed in the actual manufacturing process, for example, but not limited to, a mold tray with 20×20 holes or a mold tray with 30×30 holes.

[0026] S02: A step of fixing the bottom ends of the first tubes 20a when the first tubes 20a are placed in the first mold tray 31 and applying adhesive to the top ends of the first tubes 20a. 4, a stopper plate 36 is provided on one side of a first mold tray 31, first magnetic attractors 361 are provided on at least two corners of the stopper plate 36, and second magnetic attractors 316 are provided on two corners of the stopper plate 36 of the first mold tray 31 corresponding to the first magnetic attractors 361, respectively, so that the stopper plate 36 is provided on one side of the first mold tray 31 to stop the bottom ends of the first tubes 20a through the magnetic attraction between the first magnetic attractors 361 and the second magnetic attractors 316. One of the two magnetic attractors may be made of a magnetic material such as a magnet, and the other may be made of a magnetic material such as iron.

[0027] S03: A step of covering the top end of each first pipe 20a with a roll of highly permeable paper 25a and attaching it to the top end of each first pipe 20a with an adhesive. Specifically, the first mold tray 31 is transported to an adhesive application station, where adhesive is applied to the top end of the first tube body 20a using an adhesive application roller or roll, and then the highly permeable paper 25a is attached to the adhesive, and the highly permeable paper 25a is bonded to the top end by the adhesive.

[0028] S04: A step of cutting the highly permeable paper 25a at the top end of each first tube 20a into the shape of a sealing film using a die cutter to form an inner tube 20 having a sealing portion of the highly permeable paper 25a The die cutter also has a circular blade array (not shown) corresponding to the lattice arrangement of the first mold tray 31, and cuts the highly permeable paper 25a at the top end of each first tube 20a into a circular sealing film through the circular blade array, and the inner diameter of the circular blade in the circular blade array is larger than the outer diameter of the first tube 20a.

[0029] S05: As shown in FIG. 5, the second tubes 10a are arranged in a regular order on the second mold tray 32, one end of the second tubes 10a is filled with the smoke generating material 12, and the other end is turned upward, so that the second tubes 10a are prefabricated bodies of the outer tubes 10, and the second mold tray 32 has a lattice arrangement of the same number and arrangement as the first mold tray 31. This step is basically the same as S01, but the main differences are the size of the tubes and the size of the mold tray. The second mold tray 32 also has a stopper plate 37 for stopping the bottom end of the second tube 10a, and also has magnetic suction devices 326, 372 for connecting the second mold tray 32 and the stopper plate 37.

[0030] In step S05, one end of the second tube 10a is filled with a smoke generating agent 12, and the end of the second tube 10a filled with the smoke generating agent 12 is turned upward, and the second tube 10a is packaged in the same process as steps S02, S03, and S04 to form an outer tube 10 having a sealing portion made of highly permeable paper 25a.

[0031] S06: A step of aligning the first mold tray 31 and the second mold tray 32, placing the end of the inner tube 20 (i.e., the first tube 20a) having the sealing portion of the highly permeable paper 25a downward, and pushing each inner tube 20 into the outer tube 10 (i.e., the second tube 10a) via a push pin mold plate, inserting the entire inner tube 20 into the outer tube 10, and then filling the filter body 13, thereby obtaining the cartridge for non-combustion heated tobacco. Specifically, the pushpin mold plate has a pushpin array corresponding to the lattice arrangement of the first mold tray 31, the outer diameter of the pushpins in the pushpin array is smaller than the inner diameter of the second tube 10a and larger than the inner diameter of the first tube 20a, and the length of the pushpins in the pushpin array is longer than the length of the filter body 13. The pushpin mold plate is attached to a bracket, and during the operation of step S06, two mold trays 31 and 32 are placed under the pushpin mold plate and aligned, and then the pushpin mold plate is moved downward a predetermined distance to push the first tube 20a to a predetermined depth in the second tube 10a, for example to contact the smoke generating body, and the position of the inner tube 20 in the outer tube 10 is controlled by accurately controlling the distance of the downward movement of the pushpin mold plate.

[0032] It should be noted that the present invention is not limited to the above-described embodiments, and a person skilled in the art may make various modifications based on the creative spirit of the present invention, and such modifications should be included in the scope of protection claimed by the present invention.
