AI Technical Summary
Existing cigarette flavorings are prone to volatilization during storage, making the release of aroma uncontrollable. Furthermore, the release of flavorings in flavor capsules is uneven, making it impossible to maintain a stable release of aroma throughout the smoking process.
A porous flavoring block is designed and placed inside the hollow transparent window section of a cigarette. The flavoring substance is slowly released through the porous structure. Combined with a flavor-locking layer, the flavoring release is controlled. The flavoring block can be manually squeezed to release the flavor during the smoking interval.
It achieves a slow and sustained release of fragrance, enhancing the enjoyment of the smoking experience and the stability of the aroma, while avoiding the intense and rapid decline of fragrance after a one-time release.

Abstract
Description
Technical Field
[0001] This invention belongs to the field of cigarette technology, specifically relating to a cigarette with porous flavoring blocks and its method of use. Background Technology
[0002] The flavor of existing cigarettes is mainly adjusted in two ways: one is to pre-add flavoring to the tobacco segment or filter. This method has the drawback that the flavoring is prone to volatilization during storage and the amount of flavoring released is uncontrollable. The other is to set flavor capsules, such as flavor capsules, in the filter. The flavor capsule contains liquid flavoring extract. The flavoring is released by breaking the flavor capsule. However, the flavor is released all at once after the flavor capsule is broken. The flavor is often strong when the flavor capsule is first broken, but the flavor concentration drops quickly after a few puffs. It is impossible to maintain a stable release of flavor throughout the smoking process.
[0003] This application is submitted in order to address the above issues. Summary of the Invention
[0004] This invention discloses a cigarette with a porous flavoring block, the cigarette comprising: a tobacco segment 1 and a filter segment 2 arranged from upstream to downstream;
[0005] The filter section 2 includes: an upstream cellulose acetate section 2-1, a hollow transparent window section 2-2, and a downstream cellulose acetate section 2-3;
[0006] A porous spice block 3 is provided inside the hollow transparent window section 2-2;
[0007] The porous fragrance block 3 includes a foam porous block substrate with a porous structure containing fragrance-enhancing substances.
[0008] The porosity of the porous foam block substrate with a porous structure is 70-80%.
[0009] Preferably, the preparation method of the porous spice block 3 includes the following steps:
[0010] (1) Preparation of porous foam substrate;
[0011] (2) Vacuum the foam porous block substrate to remove the air from the pore structure of the foam porous block substrate.
[0012] (3) Prepare the fragrance liquid, and then immerse the foam porous block substrate after vacuuming in step (2) in the fragrance liquid;
[0013] (4) Take out the foam porous block substrate soaked in fragrance liquid in step (3), and then set a fragrance-locking layer on the surface to obtain the porous fragrance block.
[0014] Preferably, the flavoring agent in the flavoring liquid is selected from one or more of the following: menthol, ionone, ethyl maltol, vanillin, or rose absolute.
[0015] Preferably, in step (1), the method for preparing the porous foam substrate includes:
[0016] 01) Mix polysaccharide powder, foaming agent, dispersant, and coagulant, and then dissolve them in an alcohol solution with a volume concentration of 0-15% to prepare a foaming slurry;
[0017] 02) Pour the foaming slurry obtained in the previous step into a hollow mold and place it under high temperature for 5-20 minutes to foam the composition.
[0018] 03) Place the foamed composition obtained in the previous step into a freezer at -15 to -25 degrees Celsius and freeze for 12-48 hours. Take it out and let it air dry or bake it to obtain the foam porous block substrate.
[0019] In step 01), the polysaccharide powder is selected from one or more of the following: konjac, starch, modified starch cellulose, or glucomannan; the foaming agent is selected from one or more of the following: foaming agent AC, foaming agent H, foaming agent OBSH, and foaming agent TSH; the dispersant is selected from one or more of the following: OP-10, Span80, and sucrose ester; and the coagulant is selected from sodium carbonate.
[0020] In step 02), the foaming conditions are foaming in an oven, drying room or oil bath at a temperature of 160-240℃.
[0021] In step (3), the soaking time is 1-10 minutes.
[0022] Preferably, in step (4), the method for setting the fragrance-locking layer on the surface is as follows:
[0023] The foam porous block substrate, which is soaked in fragrance liquid, is immersed or sprayed with the dissolved film-forming material, and then dried at 40-60 degrees Celsius to form a fragrance-locking layer.
[0024] The film-forming material is a chitosan solution, a modified starch solution, a cyclodextrin solution, a gum arabic solution, or a hydroxypropyl methylcellulose solution. The above solutions are aqueous or alcoholic solutions. When using chitosan, an appropriate amount of acid is added to dissolve it.
[0025] Preferably, the upstream cellulose acetate segment 2-1 and the downstream cellulose acetate segment 2-3 are separated by a certain interval, and a porous fragrance block 3 is placed in this interval. Then, the filter segment 2 is formed by wrapping it with transparent molding paper.
[0026] The gap between the upstream cellulose acetate segment 2-1 and the downstream cellulose acetate segment 2-3 forms a hollow transparent window segment.
[0027] Preferably, the porous spice block 3 has a size of 2.8-4.2 mm. When the porous spice block has a spherical structure, the diameter of the spherical structure is 2.8-4.2 mm.
[0028] A second aspect of this application provides a method of using the cigarette described in the first aspect, the method comprising the following steps:
[0029] When the cigarette is lit, the porous flavoring block 3 inside the hollow transparent window section 2-2 is squeezed before or during smoking to release its aroma. When smoking, the aroma mixes with the smoke and enters the user's mouth.
[0030] The suction interval refers to the interval between each suction and the next suction.
[0031] Preferably, the porous spice block 3 is squeezed before each puff.
[0032] Porous spice blocks can be any shape, such as spherical or columnar.
[0033] Compared with the prior art, the present invention has the following beneficial effects:
[0034] 1. This application provides a cigarette with a porous flavoring block. The porous flavoring block is located in a hollow transparent window section, so that the user will naturally notice the ball and want to squeeze it when inhaling. When the user inhales, squeezing the ball before or between inhalations causes the flavoring within the porous foam base of the ball to be slowly released through the pore structure and enter the user's mouth with the smoke. Compared to the one-time release of flavor after the flavor capsule bursts, the porous flavoring block of this application can achieve a slow and sustained release of flavor throughout the entire smoking process.
[0035] 2. On the other hand, because the porous foam base inside the sphere has a porous structure after foaming, only the fragrance-locking layer will break when squeezed, rather than bursting, resulting in a soft feel. This increases the user's desire to squeeze it by hand, enhancing the fun. Attached Figure Description

[0073] Light the cigarette and inhale it through the downstream acetate fiber section 2-3 while manually squeezing the porous flavor block 3 inside the hollow transparent window section 2-2 to release its aroma.
[0074] Example 1
[0075] 1. Preparation of porous spice blocks 3:
[0076] (1) Preparation of porous foam substrate:
[0077] 01) Mix 5g of konjac powder, 1.2g of foaming agent AC, 0.8g of dispersant OP-10, and 0.5g of coagulant sodium carbonate, and dissolve them in 2L of 15% alcohol solution to prepare a foaming slurry;
[0078] 02) The foaming slurry obtained in the previous step is poured into a hollow sphere mold and placed in an oven at 160°C for 10 minutes to foam the foamed composition; the hollow sphere mold has a series of spherical grooves with a diameter of 3mm.
[0079] 03) Place the foamed composition obtained in the previous step into a freezer at about -20°C and freeze for 12 hours. Take it out, dehydrate it, and let it dry naturally to obtain the foam porous block substrate with a porosity of 70%.
[0080] (2) Place the porous foam block substrate at -0.08MPa for 15 minutes to vacuum it and remove the air from the pore structure of the porous foam block substrate.
[0081] (3) Immerse the vacuum-sealed porous foam block substrate in rose essential oil for 2 minutes;
[0082] (4) Take out the foam porous block base soaked in rose essential oil, centrifuge for 30 seconds to remove excess essential oil from the surface, then soak it in 2wt% ethyl cellulose ethanol solution, air dry for 10 minutes, and ethyl cellulose will form a fragrance-locking layer on the surface, finally obtaining porous fragrance block 3.
[0083] After testing, the porous fragrance block 3 was found to be spherical with a diameter of 3.2 mm. The oil content of the porous fragrance block was 0.045-0.055 g / block, and the fragrance-locking layer thickness was 0.1 mm.
[0084] 2. Separate the upstream cellulose acetate segment 2-1 and the downstream cellulose acetate segment 2-3 at a certain interval, place a porous fragrance block in this interval, and then wrap it with transparent forming paper 4 to form the filter segment 2.
[0085] The filter section 2 and the tobacco section 1 are rolled together with cigarette paper 5 to obtain a cigarette with porous flavoring blocks.
[0086] Both the upstream cellulose acetate segment 2-1 and the downstream cellulose acetate segment 2-3 mentioned above are cellulose acetate bundles.
[0087] Specifically, the upstream and downstream acetate fiber segments are spaced 3.5 mm apart to accommodate the porous fragrance blocks.
[0088] Comparative Example 1
[0089] A 3.2mm diameter rose oil-containing capsule is used instead of a porous flavoring block. The rose oil content in the capsule core is the same as the oil content in the porous flavoring block, while the other structures of the cigarette remain unchanged.
[0090] Performance testing:
[0091] A smoking test was conducted using the cigarette from Example 1. During Example 1 smoking, the porous flavoring block was squeezed before each puff. Squeezing the porous flavoring block caused the flavor-locking layer on its surface to rupture naturally. In Comparative Example 1 smoking, the flavor capsule was only squeezed before the first puff. The pressure applied to squeezing the flavor capsule and the porous flavoring block was 2.5-4 N; in this test, it was set to 3 N. Each cigarette was smoked for eight puffs.
[0092] According to GB5606.4-2005 "Cigarettes Part 4: Sensory Technical Requirements", sensory evaluation was conducted based on the specified index setting, evaluation process, and scoring rules. Thirty cigarettes each from Example 1 and Comparative Example 1 were selected, sealed, and balanced for 24 hours before being randomly coded. Ten evaluators with over one year of experience were selected as the evaluation team, primarily examining six indicators: gloss, aroma, harmony, off-flavors, irritation, and aftertaste. The scoring values for the six quality indicators were as follows: gloss 0-5 points, aroma 0-32 points, harmony 0-6 points, off-flavors 0-12 points, irritation 0-20 points, and aftertaste 0-25 points. The total score for the six evaluation indicators was 100 points. Higher scores for gloss, aroma, harmony, and aftertaste indicated a stronger sensory experience for that indicator. Higher scores for off-flavors and irritation indicated a less pronounced sensory experience during smoking. A higher total score for all six indicators represented a better smoking experience. The final evaluation results are shown in Table 1.
[0093] Table 1
[0094]
[0095] As shown in Table 1, Example 1 exhibits better aroma harmony compared to Comparative Example 1. This is because the porous flavoring block of this application allows for a slow and sustained release of aroma throughout the entire smoking process, resulting in a richer aroma and better smoke harmony. In contrast, the flavor capsule in Comparative Example 1 only releases aroma once during the initial smoking phase, with insufficient aroma in the later stages, thus resulting in poorer aroma harmony. Furthermore, Example 1 is superior to Comparative Example 1 in terms of irritation and aftertaste.
