Description

Filters and smoking articles for smoking articles in which tobacco odor is reduced by applying additives and fragrances for reducing substances that cause tobacco odor

The present invention relates to filters and smoking articles for smoking articles in which tobacco odor is reduced by application of a tobacco odor reducing additive and fragrance.

Tobacco smoke generated through smoking can be divided into main stream smoke that passes through a cigarette filter and is delivered to the mouth, and side stream smoke that is generated into the air without passing through a filter.

Components that cause the smell of tobacco contained in mainstream smoke and sidestream smoke soak into the fingers of the smoker who grips the cigarette and cause a unique smell of cigarettes, cause bad breath after smoking, or cause cigarette smoke to people other than the smoker. It is likely to cause discomfort.

Accordingly, it is necessary to develop a smoking article that minimizes the smell of tobacco on the fingers during smoking, reduces bad breath after smoking, and reduces the discomfort felt by non-smokers due to secondhand smoke.

However, these examples are for explaining the present invention in more detail, and the scope of the present invention is not limited to these examples.

- Example

(One) Check the reduction effect of nitrogen compounds according to the type of filter

The present inventors produced smoking articles having the configuration shown in Table 1 below, and compared the expression level (hand odor expression level) of odor-inducing components for each smoking article based on nitrogen compounds that are semi-VOCs (Table 1). 2 and Figure 2).

* Mono filter: Acetate filter without activated carbon

* Acetate filter: Apply 2 acetate filters without activated carbon

	TPM	Pyridine	3-ethyl pyridine	3-ethenylpyridine	Nicotine	Pyridine/TPM
Example 1	14.31	0.10	0.02	0.03	2.33	0.007
Example 2	13.39	0.03	0.01	0.03	2.54	0.002
Comparative Example 1	13.25	0.20	0.03	0.06	2.08	0.015

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 the TJNS filter, compared to the case of Comparative Example 1 using only the acedual filter, the nitrogen compound pyridine (Pyridine), 3-ethyl pyridine, 3-ethenyl pyridine, and pyridine/TPM were reduced, which was confirmed by (super) activated carbon or TJNS When is applied, it is determined that the odor-causing components remaining in the filter during the resting period (from inhalation to inhalation again) are adsorbed to activated carbon or a solvent such as MCTG, thereby reducing nitrogen compounds.

In particular, when super activated carbon, TJNS, and capsules are simultaneously applied, it is confirmed that the level of nitrogen compounds that cause unpleasant odor is reduced by about 80% compared to the conventional (control group). It can be seen that is very large.

(2) Confirmation of reduction effect of nitrogen compounds according to filter additive content and/or capsule crushing

In the same manner as in the manufacturing method of the smoking article described above, the present inventors vary the content of solvents (MCTG and PG) included in the TJNS filter of the smoking article, or confirm the reduction effect of nitrogen compounds according to the presence or absence of capsule crushing, The results are shown in Table 3 and FIG. 3 below.
