Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is aimed at suppressing sidestream smoke generated from cigarettes when smoking cylindrical cigarettes (hereinafter simply referred to as cigarettes) such as cigarettes and cigars. This relates to smoking implements that can be used for smoking purposes. The smoke generated when smoking a cigarette is divided into mainstream smoke, which the smoker inhales into his or her body through the mouthpiece, and sidestream smoke, which rises from the lit tip, that is, the ignition point, as the cigarette burns.

Under standard smoking conditions (smoking for 2 seconds once every 7 minutes and inhaling 3!d smoke 7 times), sidestream smoke is generated more than mainstream smoke. By the way, cigarette smoke
Cigarette smoke contains harmful substances such as benzo(+L)pyrene, which is feared as a carcinogen, and it is generally acknowledged that cigarette smoke is harmful to the human body.

In recent years, in addition to the harm to smokers themselves, the problem of environmental pollution caused by toxic explosives, which are harmful to people around smokers, mainly non-smokers, has come into focus. It has been pointed out that environmental pollution caused by cigarette smoke is mainly caused by the aforementioned sidestream smoke.

Comparing the content of harmful substances in mainstream smoke and sidestream smoke, it has been proven that sidestream smoke contains far more harmful substances. 0For example, Hirata.

According to page 7.1 of ``The Medicine of Smoking'' (Kodansha), edited by Namiki, it is announced that the comparison of the harmful substance content between mainstream smoke and sidestream smoke is as shown in the following table.

It is also known in environmental engineering that the environmental pollution (indoor pollution) caused by extremely harmful sidestream smoke as described above cannot be solved by simple ventilation.

Nowadays, environmental pollution caused by second-hand smoke has become a major social problem, and smokers are not able to enjoy smoking with peace of mind, as evidenced by the anti-smoking rights, which point out that smoking is a nuisance to those around them. This situation also occurs. In addition, indirect measures such as non-smoking rooms and non-smoking cars have been taken as measures to avoid environmental pollution caused by cigarette smoke. At present, there has been little research.

In view of the current situation of slanting, the inventor of the present invention has conducted extensive research and found that by maintaining the partial sound of the cigarette's ignition point within a certain hole and improving the cigarette's ignition point, the combustion of the cigarette can be reduced to a certain extent. We discovered that it is possible to suppress second-hand smoke while allowing smokers to continue smoking, and succeeded in developing a smoking device that can protect non-smokers from the harm of second-hand smoke without depriving smokers of the pleasure of smoking. , C patent application Shoj who applied for a patent first? -1x10≠O

Suppression of sidestream smoke by keeping the cigarette's flash point within the cavity is /
This is achieved by controlling the supply of oxygen from the outside, which is necessary for cigarette combustion, by improving the flame point of the paco with the cavity wall. A 79 lance with the continuation of combustion (flame life) must be maintained.

Therefore, when using the smoking device developed earlier, it is preferable to place the fire point of the tanoko at the tip of the hole, as this will result in the longest flame life. .

In other words, as the flame point moves from the tip of the hole to the center of the hole, the sidestream smoke cutting rate increases, but on the other hand, the flame life is shortened, which causes problems in smoking. .

The present invention is disclosed in Japanese Patent Application No. 9-410110 and Japanese Patent Application No. 3
It was developed to make the smoking device disclosed in No. 9-7gλ even more effective, even if the smoking device is held at any position within the cavity. ,
In other words, when using this smoking device, even if you do not have to pay special attention to adjusting the position of the flame point in the hole, you can smoke with high sidestream smoke power, high burn rate, and long flame life. It provides ingredients. In other words, the present invention provides a structure having pores with a cross-sectional area of π12wg'' to π(r+,2)'all'', where rmmwi is the average radius of a cylindrical tobacco such as a cigarette. Therefore, on the wall surrounding the hole,
- It relates to a smoking device that suppresses the generation of sidestream smoke, characterized in that it is provided with one or more perforations and/or notches.

In the smoking device of the present invention, the perforations and cuts appropriately made in the circumferential wall of the cavity adjust the amount of oxygen supplied within the cavity. It is capable of eliminating sidestream smoke almost completely while maintaining a long flame life regardless of the position in which it is held.

The perforations and incisions of the present invention are designed to have a size and dispersion state of several 1, and a length of the holes so as to exhibit an appropriate oxygen supply ability and extend fire life without impairing the sidestream smoke suppression effect. It will not appear unless the design takes into account the size and diameter. In the present invention, an important factor that influences the appropriate oxygen supply capacity is the ratio of the total area B of the perforations and cuts to the total circumferential area A of the holes.

Therefore, in the present invention, the cross-sectional area of the hole is π12wg"
~K (r + J)”as’ (r-radius of hole)
The above ratio (B/Ax 100) when in the range of
It is preferable that the ratio is j or more and 75% or less.

In other words, in this case, if it is less than j%, sufficient oxygen supply capacity to prolong the fire life will not be achieved.On the other hand, if it exceeds 15%, the oxygen supply capacity will be excessive, and the original purpose of suppressing sidestream smoke will not be achieved. physical functions are inhibited.

Furthermore, when the above ratio (/Ax 100 ) is satisfied, the object of the present invention is also influenced by the relationship between the hole diameter 2r and the hole size 1, for example, if the hole is circular, the diameter φ. For example, when the diameter of the perforation (in the case of a circular shape) is φ-t, r m, the cutting rate of sidestream smoke was measured by a sensory test in relation to the diameter of the perforated hole, 2r. The results are shown in the table below.

The shape of the perforations in the present invention may be circular, oval, triangular, irregular, or any other shape. Also, the direction of the cut is parallel to the sleeve.

It can be in any direction, such as perpendicular or inclined.

Furthermore, a combination of perforations and notches may be provided.

A structure having a hole like the one of the present invention and having a plurality of perforations or notches on the wall surrounding the hole is generally cylindrical in many cases, but is not necessarily cylindrical, for example, it has a cubic shape. ,
Alternatively, it may have a hole passing through the sphere, and one or more perforations or cuts extending through the circumferential wall of the hole and reaching the hole. Furthermore, the smoking implement of the present invention includes not only the above-mentioned structure alone, but also a smoking implement partially constituted by this structure.

In addition, including the case of a cylindrical body, the length of the hole that is sufficient to extract the fire point of the tanoko and cut off the side stream smoke is at least two lengths, and there is no particular limitation. Practically speaking, it is preferable that the length is 10 wm or more, and in some cases, the length may cover the entire length of the cigarette.

Any material may be used, such as metal, plastic, flame retardant paper, ceramic paper, processed paper, etc., but it is preferable that it be as thin and lightweight as possible.

The present invention will be described in more detail below with reference to the drawings showing specific examples of the smoking device of the present invention in the case of a cylindrical body.

FIG. 1 shows an example of the smoking implement of the present invention, where Q- is a perspective view, the book is a XX' cross-section, and C is a YY' cross-section. That is, circular perforations 3 are made in the peripheral wall of the cylinder body l.As can be seen from the XX' and YY' cross sections, there are three perforations in each row toward the lug. It has four rows.

The smoking device of the present invention constructed in this way is used by inserting and holding a cigarette into the cylinder body l, as shown in FIG. 2, and as shown in FIG. By covering the fire point j, sidestream smoke is cut, and in this case, the lack of air supply from the tip of the cylinder is replenished by the air supplied from the perforation 3, improving the fire life of the fire point j. be.

FIG. λ shows a state in which sidestream smoke 7 is generated when the fire point j'lt is exposed from inside the cylinder body l.

As illustrated in FIG. 2, this is an example of the smoking implement of the present invention.
It is possible to inhale Tanonoko Hiro while it is attached to the barrel body/i-cigarette μ, but in this case, as shown in Figure λ, slide the barrel body l to the side of the tapacog mouthpiece. The fire point may be exposed from the SF cylinder main body l, and the λth
As shown in Figure d, suction is possible even when the spark point 5 is wrapped around the cylinder body l. -This is because when air is introduced through the tip of the cylinder and the perforation J by suction, it is possible to continue smoking the cylinder.

As illustrated in FIG. 1, the smoking article of the present invention is used by directly attaching a structure having a hole and a plurality of perforations or cuts on the wall surrounding the hole to a tongue. In addition to those in the form shown in Figure 3, there is no change in the sidestream smoke suppressing effect when kept, and they greatly contribute to eliminating environmental pollution caused by tobacco sidestream smoke.

FIG. I will fulfill it. 2 is a pipe with perforations 3, but it also has a non-perforated part of an appropriate length on one end of the cylinder body. It is configured so that it can be used. Reference numeral 4 is a cube having a hole and a perforation 3 formed in the peripheral wall thereof, and is an example of a shape other than a cylinder.
