Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cigarette mouthpiece used during smoking, and more particularly to a cigarette mouthpiece equipped with a novel ventilation means.

In recent years, due to the problem of health problems caused by smoking, efforts have been made to develop cigarette filters and cigarette mouthpieces that can reduce harmful components contained in cigarette smoke.

For this purpose, methods are used to dilute the cigarette smoke by introducing surrounding air into the filter or mouthpiece, and this is said to be effective.For example, by opening holes in the cigarette filter, Those that introduce air into the filter from the outside, U.S. Patent No. 3,323,525 and Japanese Patent Publication No. 1983
As shown in No. 9314, etc., there are known devices that have holes in the suction port and introduce air into the suction port from the outside.

These mouthpieces and cigarette filters allow the introduced air to mix with some or all of the cigarette smoke inside the filter or mouthpiece, and the diluted tobacco smoke is inhaled during the day by the smoker, resulting in cigarette smoke. Although the purpose is to reduce the harmful ingredients contained in smoking, it has the disadvantage of reducing the satisfaction of smoking.

In order to prevent this decrease in satisfaction from smoking, there is a demand for the development of a special cigarette filter that allows tobacco smoke and introduced air to mix for the first time during the smoker's day.For example, British Patent No. 8642'47 No., Special Publication Showa 54-396
No. 0, JP-A-55-141.84, JP-A-56-64
A specific example is given in No. 778. In this way, it has been empirically known that by separating the cigarette smoke and the introduced air and delivering them to the smoker's mouth, the flavor of the smoke can be enhanced and the decrease in satisfaction from smoking can be prevented. There is.

However, all of these are cigarette filters that are integrated with the cigarette, and there are very few types of cigarettes that have these cigarette filters attached. The current situation is that this is not possible.

Therefore, the present inventor has developed a cigarette mouthpiece that can be easily attached to a cigarette that a smoker regularly smokes, that allows outside air to be introduced during smoking, reduces harmful components in tobacco smoke, and that reduces the feeling of satisfaction when smoking. As a result of studies aimed at developing a cigarette mouthpiece, a cigarette mouthpiece having an internal ventilation passage and an external ventilation passage, the internal ventilation passage having a space for attaching a cigarette at one end, and the above-mentioned a space that communicates with the space and extends through the length of the shaft, the external air passage having an air passage that communicates directly with the outside and directly into the smoker's day; the internal air passage and the external air passage; This purpose is achieved by separating air introduced from the outside and tobacco smoke and transporting them during the smoker's daytime using a cigarette mouthpiece characterized by a channel separated by an air-impermeable material. The present invention was completed after discovering what could be achieved. 'The present invention further provides a cigarette mouthpiece with a filter in which a filtration substance for tobacco smoke is provided in the tobacco smoke ventilation path, and furthermore, the present invention provides a cigarette mouthpiece with a filter in which a filtration material for tobacco smoke is provided in the tobacco smoke ventilation path, and furthermore, the present invention provides a cigarette mouthpiece in which the degree of dilution can be controlled according to the will of the smoker. It provides a mouthpiece for use.

Hereinafter, the present invention will be explained based on the drawings.

FIG. 1 shows a perspective view of an example of the cigarette mouthpiece of the present invention, FIG. 2 shows a sectional view in the longitudinal direction of the shaft of the cigarette mouthpiece, and FIG. 3 shows a front view of A in FIG. 4 is a sectional view perpendicular to the longitudinal direction of the axis in FIG. 2, and FIG. 5 is a rear view of FIG. 2. This cigarette mouthpiece (1) is provided with an internal ventilation path (3) and an external ventilation path (5), and one end of the internal ventilation path (3) is provided with an internal ventilation path (3) and an external ventilation path (5). A space (4) for attaching a cigarette is provided. On the other hand, the external ventilation path (5) is constituted by a groove provided on the outer surface of the mouthpiece (1) and the envelope (2), and is provided with an opening (6) that directly communicates with the outside. When a cigarette is installed in the mounting space (4) and smoked, the tobacco smoke passes through the internal ventilation passage (3), and the air introduced from the outside passes through the opening (6) and the external ventilation passage. Through (5),
Each item will be separated and transported to the smoker during the day.

Figures 6 and 8 show that the suction port (1) is connected to the external ventilation passage (

FIG. 10 shows a cigarette mouthpiece in which the external air passage is constituted by a groove (5) provided on the outer surface of the mouthpiece ( ) and the smoker's lips.

Fig. 12 shows a cigarette mouthpiece in which a filtration material (7) for tobacco smoke is inserted into a part of the space (3) passing through the shaft in the longitudinal direction, and Fig. 13 shows a cigarette mouthpiece in which a filtration material (7) for tobacco smoke is inserted. A cigarette mouthpiece is shown in which a filtration material (7) for tobacco smoke is inserted in a part of the space (4).

In the cigarette mouthpiece shown in FIGS. 2, 12, and 13, the wrapper (2) is made easily movable in the axial direction,
If the size of the opening (6) and the length of the external ventilation path (5) are changed, the amount of air introduced from the outside will also increase or decrease accordingly, so smokers can adjust the dilution level according to their own will. can be controlled. Furthermore, the same effect can be obtained with the cigarette mouthpiece shown in FIG. 10 by changing the position where the mouth is gripped with the lips.

Materials for the cigarette mouthpiece (1) of the present invention include plastics such as polymethacrylate, polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyacetyl, and ABS, as well as metals such as gold, silver, stainless steel, and aluminum. Substantially air-impermeable wood, stone, etc. can be used. Materials for the envelope (2) include polyvinyl chloride, polytetrafluoroethylene, and rubber sleeves, as well as sellotape and pre-perforated materials. It is possible to use chive paper etc.

In addition to the filter plug made of acetate fiber, which is the most common cigarette filter material, polyurethane sponge, sea sponge, sintered metal sponge, etc. can be used as the material for the filtration material (7) for tobacco smoke. be able to.

Next, the present invention will be explained in more detail with reference to Examples.

Example Smoking test results of the commercially available cigarette "Highlight" from which the filter was removed are shown in Table 1 AI.
Table 1 shows the smoking test results of the filters removed from "Highlights" and 20 length filters made of 43,000 filament acetate tow with a Y cross section of 4 denier and having an airflow resistance of 50 mm H2O.

．． The results of the smoking test with four holes drilled in column 07 φ at the 5 mm position are shown in the first table plate 3, and the results of the smoking test with the same eight holes made are shown in the first table plate 4. It was shown to.

Next, the smoking test results of the mouthpiece of the present invention having the structure shown in FIG. 2 attached to a cigarette cylinder of the same type as 52 are shown in Table 1, Panel 5 and Panel 6.

Next, the smoking test results of a commercially available cigarette "Highlight" with the filter removed and attached to the tobacco mouthpiece of the present invention shown in Figure 6 are shown in Table 1, Part 7 and Part 9. Table 1 A 8 and Flat 10 show the smoking test results of a sample of the same type as Flat 2 attached to a cigarette mouthpiece of the present invention having the structure shown in FIG. 6.

Next, the smoking test results of the same type of sample as in Section 2 attached to the cigarette mouthpiece of the present invention shown in FIG. 10 are shown in Tables 1 A 11 , JlG, 12 and A 13 .

Further, a cigarette mouthpiece of the present invention shown in FIG. 12,
Airflow resistance 50W+L made of acetate tow of 2.2 denier Y cross section 40,000 filament as filter material
Table 1 shows the results of a smoking test on a 5 mm long H2O cigarette bonded to a commercially available cigarette "Highlight" with the filter removed. As a material, 4 of 22 denier Y cross section
A 12.5 mm long piece made of 0,000 filament acetate tow with a ventilation resistance of 50 wn H2O was similarly bonded to a cigarette, and the results of the same smoking test are shown in Table 1, Table 15, and also in Figure 13. As a filter material, 22 denier Y cross section 40. Ventilation resistance 50mH2 made of OOO filament acetate tow
The first table 16 shows the results of a smoking test on a product having a length of 12.5+n+n and attached to a cigarette.

As can be seen from the above examples, it is presumed that the cigarette mouthpiece of the present invention reduces the amount of smoked smoke, and thereby reduces harmful components to the same extent.

Furthermore, in smoking evaluation tests, for example, 3 and 8
Comparing and smoking ``Ban】0, ``Ban 8'' and ``510'', which use the cigarette mouthpiece of the present invention, show that the amount of smoked is small, but the smoker does not struggle, and the smoker has a good aroma and taste. I was able to enjoy smoking that gave me a good feeling.

Each measurement item in Table 1 was measured as follows.

Ventilation resistance: The flow rate of air passing through a filter, etc. is 17
．． The pressure loss of the filter etc. at 5 rnl/sec was expressed in water column (, mH, , O).

Automatic smoking was performed using a constant flow type automatic smoking machine with a flow rate of 17.5 ml/sec ATM, a smoking time of 2 seconds, a smoking interval of 58 seconds, and a cigarette combustion length of 50 mm, and the mainstream smoke was collected using a Cambridge filter. It was determined by analyzing this.

Removal rate: Automatically smoke in the same way as the measurement of smoking amount above, analyze what is collected in the filter and lacrimal material,
This is expressed as a value obtained by dividing the amount collected by the filter or filtration material plus the amount of smoking, multiplied by 100.
