[0025] The present invention provides a cigarette with a 4D printed flavor carrier model. The cigarette comprises a filter rod with a window and a cigarette body. The 4D printed flavor carrier model is arranged in the filter rod with a window. The 4D printed flavor carrier model is prepared by 4D printing of flavor and printing material. The printing material is selected from a composite material of one or more of potato starch and modified starch and sodium alginate.

[0026] In the present invention, the filter rod with a window comprises:

[0027] Two sections of filter rod tow, and a transparent cavity arranged between the two sections of filter rod tow;

[0028] A 4D printed incense-carrying model is arranged in the transparent cavity;

[0029] The tipping paper wraps two sections of filter rod tow, and the tipping paper has a transparent visible window at a position corresponding to the transparent cavity of the filter rod.

[0030] See also Figure 1 , Figure 1 A schematic diagram of a cigarette provided by the present invention, wherein from left to right are a photo of a cigarette (wherein a 4D printed fragrance carrier model is not set in the transparent cavity), an enlarged view of a filter rod with a window, a schematic diagram of a 4D printed fragrance carrier model, and a rendering of a cigarette after a 4D printed fragrance carrier model is set in the transparent cavity of the cigarette.

[0031] In the present invention, the height of the transparent cavity is 3-5 mm, preferably 3, 3.5, 4, 4.5, 5, or any value between 3-5 mm, and the volume is 31.5-100 mm 3 .

[0032] The size of the transparent cavity is adjusted according to the specifications of the cigarette, and the cigarette of the present invention is selected from conventional cigarettes, large and medium cigarettes or slim cigarettes. When the cigarette is a conventional cigarette, the volume of the transparent cavity is 100mm 3 When the cigarette is a large or medium cigarette, the volume of the transparent cavity is 56 mm 3 When the cigarette is a slim cigarette, the volume of the transparent cavity is 31.5 mm 3 . See Figure 2 , Figure 2 Schematic diagram of the transparent cavity structure in cigarettes of different specifications.

[0033] In the field of cigarettes, no matter what size of cigarettes, the volume of the required three-dimensional model is very small. This requires fine CAD modeling of the printed three-dimensional model to facilitate printing of small-sized, high-precision, high-quality three-dimensional models.

[0034] In some specific embodiments of the present invention, the 4D printed incense carrier model is selected from a three-dimensional model with the appearance of the Yellow Crane Tower, a cylinder, a cone, a hexahedron, or a heart-shaped cross-section. Figure 3 , Figure 3 This is the CAD digital design drawing of the Yellow Crane Tower.

[0035] For this reason, the three-dimensional models used in cigarettes have small size, so not only high requirements for precision are required, but also certain requirements for material safety, flavor encapsulation efficiency, and flavor sustained-release effect.

[0036] Therefore, the printing material selected in the present invention is a compound material of one or more of potato starch and modified starch and sodium alginate. The modified starch is selected from one or more of cassava modified starch, corn modified starch, pregelatinized starch and cross-linked starch.

[0037] The composite material has good molding effect, high printing accuracy, and is safe, and has high embedding efficiency for flavors and good sustained-release effect.

[0038] In the present invention, the mass ratio of one or more of the potato starch and modified starch to sodium alginate is 2-3:1, preferably 2:1, 2.5:1, 3:1, or any value between 2-3:1.

[0039] In some specific embodiments of the present invention, the printing material also includes xanthan gum, and the mass ratio of one or more of the potato starch and modified starch, sodium alginate and xanthan gum is 2~3:1~2:1~2, preferably 2:1:1, 3:2:2, 2.5:1.5:1.5, or any value between 2~3:1~2:1~2.

[0040] In the present invention, the flavor is selected from monomer flavors or compound flavors, preferably one or more of raspberry ketone, menthol, cantaloupe flavor and blueberry flavor.

[0041] The present invention also provides a method for preparing the above-mentioned cigarette having a 4D printed fragrance-carrying model, comprising the following steps:

[0042] A) mixing essence, printing material and water to obtain a mixed material;

[0043] The mixed material is placed in a 4D printer for 4D printing to obtain a 4D printed fragrance-carrying model;

[0044] B) placing the 4D printed fragrance carrier model in a transparent cavity of a filter rod with a viewing window to obtain a filter rod;

[0045] C) Connecting the filter rod to the cigarette body to obtain a cigarette with a 4D printed fragrance carrier model.

[0046] Specifically, the printing material and water are uniformly mixed to obtain a printing material mixture; wherein the mass ratio of the printing material to water is 1 to 8:10, preferably 1:10, 3:10, 5:10, 6:10, 8:10, or any value between 1 and 8:10;

[0047] The function of the printing material mixture is to ensure better molding of the model. Specifically, the printing material mixture is prepared by mixing powdered printing material and boiling water, wherein the mass ratio of the powdered printing material to boiling water is 1-4:1, preferably 1:1, 2:1, 3:1, 4:1, or any value between 1-4:1.

[0048] Adding the flavor to the printing material mixture cooled to room temperature to obtain a mixed material; wherein the mass ratio of the flavor to the printing material mixture is 1 to 5:100, preferably 1:100, 2:100, 3:100, 4:100, 5:100, or any value between 1 and 5:100;

[0049] The mixed material is placed in a 4D printer for 4D printing to obtain a 4D printed fragrance-carrying model.

[0050] The 4D printer is a food 3D printer with dual nozzles. During the printing process, the nozzle is at 210°C and the platform is at 60°C.

[0051] After obtaining the 4D printed fragrance carrier model, the 4D printed fragrance carrier model is placed in a transparent cavity of a filter rod with a window to obtain a filter rod;

[0052] Finally, the filter rod is connected to the cigarette body to obtain a cigarette with a 4D printed fragrance-carrying model.

[0053] The present invention has no special restrictions on the preparation method of the two sections of filter rod tow in the filter rod and the cigarette body, and any method known to those skilled in the art can be used.

[0054] The present invention applies 4D printing technology to cigarettes, uses 4D printing technology to prepare a three-dimensional model, and places it in the filter rod. Develop a three-dimensional fragrance-carrying model to replace the popping beads, giving the window cigarettes a new visual impact effect; the three-dimensional model has the functions of adding color and carrying fragrance, which can echo the cigarette design concept in many aspects. In addition, the present invention selects a specific type of printing material, which can significantly improve the embedding efficiency of the flavor and the sustained release effect of the flavor while having a good molding effect.

[0055] In order to further understand the present invention, the cigarette with a 4D printed fragrance-carrying model provided by the present invention, its preparation method and application are described below in conjunction with embodiments. The protection scope of the present invention is not limited by the following embodiments. Example

[0056] 1. See Table 1, which shows the ratios, appearances, and molding effects of the filter rod gel models after printing of different types of printing materials.

[0057] Among them, the printer uses a dual-nozzle food 3D printer, and the printing parameters are printing nozzle 210℃ and printing platform 60℃.

[0058] Table 1 Ratio, appearance and printing effect of different types of printing materials

[0059]

[0060] From the perspective of molding effect, potato starch alone, regardless of whether it is soluble in cold water, has an inappropriate hardness after molding and is easy to break. After potato starch (soluble in cold water) is mixed with carrageenan or xanthan gum, the hardness is relatively soft, and although it has elastic deformation, it is slightly sticky and is not suitable for cigarette products. However, the compound material of potato starch (soluble in cold water) and sodium alginate and xanthan gum has moderate hardness after molding, good molding effect, elastic deformation and no stickiness, so these two formulas are suitable for the needs of cigarette products.

[0061] 2. Preparation of 4D printed incense carrier model

[0062] Mixing the printing material and water uniformly to obtain a printing material mixture, wherein the mass ratio of the printing material to the water is 1:10; adding the essence to the printing material mixture after cooling to room temperature to obtain a mixed material, wherein the mass ratio of the essence to the printing material mixture is 3:100;

[0063] The mixed material is placed in a 4D printer for 4D printing to obtain a 4D printed fragrance carrier model. During the printing process, the print head is 210°C and the printing platform is 60°C.

[0064] The project evaluated the fragrance effect of the monomer fragrance menthol. The measurement method, encapsulation rate and retention rate used are as follows:

[0065] ①. Determination of menthol encapsulated in filter rod gel model

[0066] Weigh 1 g of the filter rod gel model sample, wash it 6 times with 30 mL of 50% (volume fraction) ethanol-water solution, pour the washing solution into a 100 mL volumetric flask, dilute to the mark with ethanol-water solution, shake well, take 1 mL of the solution and put it into a 10 mL test tube, add 5 mL of the colorimetric agent 5 mg / mL sulfuric acid solution of p-dimethylaminobenzaldehyde, determine the absorbance at 550 nm according to the above steps, and determine the menthol content on the surface of the filter rod gel model sample according to the standard curve.

[0067] ②. Menthol working curve

[0068] The standard working curve of menthol was plotted with absorbance (A) versus menthol concentration (C), and the regression equation was obtained, A=0.0064C+0.0574 (r2= 0.9996).

[0069] ③. Calculate the embedding rate of menthol in the filter rod gel model according to the following formula:

[0070] Embedding rate (%) = menthol content of filter rod gel model / designed amount of menthol in filter rod gel model × 100%

[0071] Table 2 Menthol embedding efficiency of filter rod gel model

[0072] wall material Designed loading amount of menthol (%) Menthol content (%) Embedding rate (%) Modified starch (cold water soluble): sodium alginate = 2:1 20 18.23 91.15 Modified starch (cold water soluble): sodium alginate = 2:1 30 27.12 90.40 Modified starch (cold water soluble): sodium alginate = 2:1 40 26.42 88.07 Modified starch (cold water soluble): sodium alginate: xanthan gum = 2:1:1 20 19.09 95.45 Modified starch (cold water soluble): sodium alginate: xanthan gum = 2:1:1 30 27.87 92.90 Modified starch (cold water soluble): sodium alginate: xanthan gum = 2:1:1 40 36.64 91.60

[0073] It can be seen from the table that the menthol filter rod gel model prepared with different materials can well ensure that menthol is effectively embedded. When the designed loading of menthol is the same (30%), the content of menthol in the prepared menthol filter rod gel model varies slightly according to the material, ranging from about 91% to 96%. Among them, the carrier material of polylactic acid: potato starch (cold water soluble): sodium alginate: xanthan gum = 2:1:1, when the designed loading is 20, 30 and 40%, the encapsulation rate is higher than that of potato starch (cold water soluble): sodium alginate = 2:1. It can also be seen from the above table that, under other conditions unchanged, with the increase of menthol feed, the menthol content gradually increases, but its embedding rate tends to decrease.

[0074] ④. Determination of menthol retention rate in filter rod gel model

[0075] A certain amount of filter rod gel model was placed under indoor environmental conditions (temperature about 25°C, humidity 60%), and the menthol content in the filter rod gel model was measured at regular intervals. The ability of the filter rod gel model to retain menthol was determined based on the measurement results at the beginning of storage and after a period of time.

[0076] The retention rate of menthol in the filter rod gel model was calculated according to the following formula:

[0077] Retention rate (%) = menthol content of filter rod gel model during storage / menthol content of filter rod gel model before storage × 100%

[0078] The material ratio is potato starch (cold water soluble): sodium alginate: xanthan gum = 2:1:1. When the menthol addition amount is designed to be 30%, the prepared filter rod gel model is tested for 12-month menthol retention rate according to the above method. At the same time, menthol with the same proportion is used as non-sustained-release menthol for comparative testing, and the results are as follows.

[0079] Table 3

[0080] time Filter rod gel model menthol (%) Menthol (%) Day 0 95.47 94.03 30 days 93.46 82.49 90 days 91.25 78.27 6 months 86.54 56.34 8 months 82.39 39.47 10 months 77.92 18.95 12 months 73.87 4.29

[0081] The effect of storage time on the retention rate of menthol in the filter rod gel model. The menthol content in the filter rod gel models prepared with different menthol loadings decreased with the increase of storage time. However, the retention rate of the filter rod gel model was above 70% after 90 days of storage, and the reduction of menthol content was small, indicating that the menthol wrapped in the filter rod gel model was relatively stable. Under the same conditions, menthol showed a linear downward trend after being placed for 12 months, and only 4.29% remained at 12 months.

[0082] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
