Description

A filter for a smoking product for reducing the smell of tobacco by applying an additive and a flavoring agent that reduces the smell-causing substance, and a smoking product

The present invention relates to a filter for a smoking product and a smoking product for reducing the smell of tobacco by applying an additive and a flavoring agent that reduce substances that cause tobacco smell.

The smoke produced by smoking can be divided into the mainstream smoke (main stream smoke) that passes through the tobacco filter and is delivered to the mouth, and the side stream smoke (side stream smoke) that does not pass through the filter and is produced into the air.

The components that cause the smell of tobacco in mainstream and sidestream smoke soak into the smoker's fingers, producing a unique smell of tobacco, which can cause bad breath after smoking or cause discomfort to people other than the smoker due to smoke.

Therefore, it is necessary to develop a smoking product that can reduce the smell of tobacco on the fingers when smoking, reduce the bad breath after smoking, and reduce the discomfort felt by non-smokers due to secondhand smoke.

"Smoking products" in this article may refer to items that can generate aerosols, such as cigarettes (rolling tobacco), cigars, etc. Smoking products may include aerosol-generating materials or aerosol-forming substrates. In addition, smoking products may also include solid materials based on tobacco raw materials, such as leaf tobacco, tobacco shreds and reconstituted tobacco. Smoking substances may contain volatile compounds.

In addition, throughout the specification, "upstream" or "upstream direction" refers to the direction away from the smoker's mouth, and "downstream" or "downstream direction" refers to the direction close to the smoker's mouth. For example, in the smoking product (10) shown in FIG. 1, the smoking substance part (11) is located upstream or in the upstream direction of the filter mouthpiece (12, 14).

In addition, although the present specification describes a burning type cigarette as an example of the smoking product (10), the present invention is not limited thereto, and the smoking product (10) may correspond to a heating type cigarette used together with an aerosol generating device (not shown) such as an electronic cigarette device.

According to an embodiment of the present invention, a filter for reducing tobacco odor of a smoking product is provided, comprising: a filter portion, the upstream end of which is coupled to the smoking substance portion of the smoking product; and a wrapping paper, which wraps the filter portion, wherein the filter portion comprises an additive, and the additive is one or more selected from the group consisting of medium chain fatty acid triglyceride (MCTG), propylene glycol (PG) and glycerol.

By including a liquid additive, such as medium chain fatty acid triglyceride (MCTG), propylene glycol (PG) and/or glycerol in the filter, the amount of migration of components causing tobacco odor can be reduced, and by adjusting the amount of additive added, the degree of migration of components causing tobacco odor can also be controlled.

Specifically, it is preferred that the filter included in the smoking product include one or more additives of 3.0 mg or more and 30 mg or less, wherein the additive is one or more selected from the group consisting of MCTG, PG and glycerol. If it is less than the lower limit of the above range, the effect of reducing the migration amount of the components causing the tobacco flavor may not be significant; if it exceeds the upper limit of the above range, there may be problems in operability such as filter formation, or it may affect the change of the migration amount of the nicotine component.

Furthermore, by adding a flavor liquid to the additive, a masking effect of tobacco smell can be expected.

At this time, the flavor liquid may be a reagent that imparts taste and/or fragrance to the aerosol generated by the tobacco material, and may include, for example, rosemary, oleoresin, licorice, sucrose, fructose syrup, iso sweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, bittersweet, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, peppermint oil, citrus oil, catechin, grapefruit, guarana, brandy, jasmine, cocoa butter, menthol, cinnamon, ylang-ylang oil, sage, spearmint, ginger, coriander, coffee, etc., but is not limited thereto.

In addition, the filter according to an embodiment of the present invention can be formed of filters of various materials, and as an example, it can correspond to cellulose acetate, and further, it can be a transfer nozzle system (TJNS) filter in which the fragrance liquid is perfumed.

In addition, in the case of a filter including activated carbon, in addition to the additive to which the flavoring liquid is added, the filter may be divided into two or more sections and may be divided into a first filter, a second filter, etc. In this case, as an example, when the first filter includes activated carbon, the second filter may correspond to a TJNS filter.

In addition, since components of flavor liquid such as flavor or menthol may be adsorbed when passing through activated carbon and its function may be reduced, it is preferable that the filter including activated carbon is located upstream compared to the TJNS filter.

Furthermore, as the type of activated carbon included in the filter mouthpiece, not only general activated carbon but also super activated carbon can be used, and from the perspective of reducing substances causing tobacco odor, it is more preferable to include super activated carbon.

In addition, the general activated carbon described herein may refer to activated carbon having a specific surface area of 800 to 1200 m2/g, and the super activated carbon may refer to activated carbon having a specific surface area of 1800 to 2000 m2/g or more.

In addition, the filter mouthpiece according to the present invention can also include the fragrance liquid in the form of a capsule containing the fragrance liquid.

The capsule (13) exhibits crushability that can be broken when pressure is applied, for example, when crushed by hand, the flavoring liquid inside the capsule can moisten the filter for smoking products. In addition, in the cross-section of the rod-shaped filter (14) for smoking products including the capsule (13), the capsule (13) can be located at the center thereof; and the filter including the capsule (13) can be combined with an acetate fiber bundle containing an adsorbent, etc., to adopt the form of a composite filter (e.g., a double filter or a triple filter, etc.).

As a solvent for the flavor liquid included in the capsule, for example, the above-mentioned medium chain fatty acid triglyceride (MCTG) may be included, and other substances such as pigments, emulsifiers and thickeners may also be included.

In addition, according to another embodiment of the present invention, a smoking product with reduced tobacco odor comprising a smoking substance portion, a filter portion and a wrapping paper is provided, comprising: a first filter portion, an upstream end of which is coupled to the smoking substance portion; a second filter portion, which is coupled to a downstream end of the first filter portion; a first wrapping paper wrapping the first filter portion and a second wrapping paper wrapping the second filter portion; a coupling wrapping paper, which is wrapped so that the first filter portion is coupled to the second filter portion; and a tipping paper, which is wrapped so that the smoking substance portion is coupled to the filter portion, wherein the first filter portion, the second filter portion or the first filter portion and the second filter portion include an additive, and the additive is selected from medium chain fatty acid triglycerides (MCTG, Medium chain fatty acid One or more selected from the group consisting of propylene glycol (PG, Propylene glycol) and glycerin.

Here, the smoking substance portion generally includes a tobacco material containing nicotine, which may also include a shaping agent (such as a binder or other additives, etc.). As an embodiment, the tobacco medium included in the smoking substance portion of the present invention may be prepared in the form of particles containing tobacco material and shaping agents, etc.

In the present invention, tobacco material is a material that forms an aerosol-generating matrix, and may be tobacco leaves, tobacco stems, tobacco dust generated during tobacco processing, and/or tobacco leaf strips. Tobacco leaves may be at least one selected from flue-cured tobacco, burley tobacco, oriental tobacco, cigar leaves, and roasted tobacco, but are not limited thereto.

Additionally, the filter portion constituting the smoking product may be divided into more than one segment, and all of these may be considered to include the features of a filter for a smoking product as described above.

In addition, the wrapping paper can be made of ordinary filter wrapping paper, and in order to reduce sidestream smoke, fillers such as magnesium oxide, titanium oxide, zirconium oxide, aluminum oxide, calcium carbonate and zirconium carbonate can be added, or it can be made of filter wrapping paper coupled with metal foil such as aluminum foil.

In addition, one or more perforations can be selectively formed in the circumferential direction in the tipping paper that couples the smoking substance portion and the filter, so that external air can flow in or internal gas can flow out, thereby achieving the air dilution rate of the cigarette and adjusting the migration amount of the mainstream tobacco components.

The following describes the structure and effects of the present invention in more detail through embodiments and comparative examples. However, the embodiments are used to describe the present invention in more detail, and the scope of the present invention is not limited to these embodiments.

Implementation example

(1) Confirm the nitrogen compound reduction effect according to the filter type

The inventors prepared smoking products having the structures shown in Table 1 below, and compared the expression levels of the components causing the smoke odor of each smoking product (the expression levels of the smoke odor on the hands) based on nitrogen compounds (semi-volatile organic compounds) (Table 2 and Figure 2).

*單過濾嘴：不含活性碳的醋酸鹽過濾嘴*雙乙酸鹽過濾嘴：使用2個不含活性碳的醋酸鹽過濾嘴

*Single filter: Acetate filter without activated carbon *Diacetate filter: Use 2 acetate filters without activated carbon

As shown in Table 2 and FIG. 2, in the case of Example 1 using the TJNS filter and Example 2 using the super activated carbon and TJNS filter, it can be seen that pyridine, 3-ethyl pyridine, 3-ethenyl pyridine, and pyridine/TPM, which are nitrogen compounds, are reduced compared to the case of Comparative Example 1 using only the diacetate filter, and that, when (super) activated carbon or TJNS is used, the nitrogen compounds are reduced by adsorbing the components causing tobacco odor remaining in the filter during the rest period (i.e. until re-inhalation after inhalation) into the activated carbon or solvent (e.g., MCTG).

Especially when super activated carbon, TJNS and capsules were applied at the same time, it can be seen that the level of nitrogen compounds that cause odor was reduced by about 80% compared to the conventional (control group), and the combined effect of these components was very large.

(2) Confirm the nitrogen compound reduction effect based on the additive content of the filter tip and/or capsule crushing

The inventors changed the content of the solvent (MCTG and PG) included in the TJNS filter of the smoking product in the same manner as the preparation method of the above-mentioned smoking product, confirmed the effect of reducing nitrogen compounds according to whether the capsule was crushed or not, and the results are shown in Table 3 and Figure 2 below.

As shown in Table 3 and Figure 3, it can be confirmed that the nitrogen compound reduction effect becomes more significant as the content of MCTG in TJNS increases (4.0 mg → 11 mg → 30 mg), and the reduction in nitrogen compounds tends to increase when the capsule containing MCTG is crushed with a flavoring liquid and a solvent compared to the case where the capsule is not crushed.

In summary, the embodiments are described through limited drawings, and ordinary technicians in this field can make various modifications and variations to the above description. For example, the described technology is performed in a different order from the described method, and/or the described components are combined or combined in a different form from the described method, or replaced or substituted by other components or equivalents to obtain the same effect.

Therefore, other embodiments, other examples and equivalents of the patent application scope all belong to the patent application scope.
