Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a cigarette filter, which is mainly used in a cigarette filter to remove harmful substances such as tar and nicotine contained in smoke. Regarding filters.

[Technical aspect of the invention *a and its problems] Many filters have been invented in the past to remove harmful substances such as tar, nicotine, benzopyrene and carbon monoxide contained in smoke when smoking. There is. Among them, the following filters that utilize the properties of microorganisms are particularly well-known. In other words, the special public official
- In Publication No. 22316, chlorella cells are moored to activated carbon, zeolite, various fibers, open cells, etc.
A cigarette filter is disclosed in which the cigarette filter is used as a filter for passing cigarette smoke. According to this, by mooring chlorella, a type of green algae, inside the filter,
The tar removal rate is 28%, and the nicotine removal rate is 3.
It is said that an effect of about 1% can be obtained. However, as is well known, chlorella has an adult size of 11! l
There are still problems when using chlorella, such as the fact that the size of the chlorella is only 1/100th of a meter, making it difficult to harvest the first one at 44, and the raw taste of chlorella when you put it in your mouth. There is even. Therefore, implementing the previous two inventions/
II! In order to do this, the cost of culturing chlorella increases to $131, and if 1/100th of 111 chlorella cannot be completely moored in the filter, chlorella will not be placed in the mouth. There are disadvantages such as inhalation of chlorella and the possibility that the freshness of the chlorella will spread and significantly interfere with the taste of smoking.

[Object of the invention] Therefore, the present invention not only solves the above-mentioned disadvantages, but also solves the
1. The purpose of the present invention is to provide a cigarette filter that can more effectively remove harmful substances such as tar and nicotine contained during smoking.

C Summary of the Invention 1 In order to achieve the above-mentioned object, the gist of the present invention is that spirulina is included in a predetermined cigarette filter body.

[Embodiments of the Invention] Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

Spirulina 1 used in the present invention is a type of blue-green algae, and ranges from microscopically small to macroscopically visible, and the present invention refers to all of these. The nature of Spirulina 1 is that it does not have a true nucleus, does not have glauclasts, but contains lamina cords, is superior to bacteria, and is aqueous. In addition, it has a color called phycotian and undergoes photosynthesis, but it produces starch (U1), produces protein from nitrogen in the air, and contains a large amount of protein.On the other hand, Spirulina 1 requires only water supply. Since the fruit can be harvested, it is cultivated for a large amount of 15 billion yen, and in addition to being used as food for livestock, it is also considered food for humans.

It is also being investigated as a raw material for non-polluting polymer processed products, and can be considered as one of the negative sources of the current food intake problem.

When incorporating Spirulina 1 having such properties into a filter body shaped like a vibrator, as shown in the figure, Spirulina 1 is stuffed into an appropriate position of the cylinder body 2 by suction, and Fixing spirulina 1 inside cylinder 2
The transparent body 3 is installed inside the Spirully-1. At this time, as for the material of the transparent body 3, glass wool was used in the experiment, but other materials may be used, for example, various fibers other than glass wool, open cell materials, etc. may be used. It is something. However, the transparent body 3
The spirulina 1 is used to hold the spirulina 1 in a predetermined position within the cylinder 2 rather than to filter the cooking method. Of course, it is also possible to use activated carbon, zeolite, etc. to promote purification during cooking. Furthermore, as a method of attaching the transparent body 3, in addition to the method of attaching it separately from the spirulina 1 as shown in the figure, the spirulina 1 may be attached to the transparent body 3 by mooring it, or the spirulina 1 and the transparent body 3 may be attached. It is also possible to install it in a state where it is divided into several layers. Therefore,
The method for attaching the transparent body 3 is determined depending on the size of the Spirulina 1 alone and the material of the transparent body 3.

In addition, Spirulina 1 was added to the filter body installed directly on cigarette A.
Needless to say, it is a powerful ability that encompasses the following.

[Effects of the Invention FA1] Next, the effect of the present invention on purifying bother during smoking will be explained based on test data commissioned to the Osaka Jieki Environmental Science Research Institute.

This test is as shown in the figure, Smoke! +i Pack 50 m9 of Spirulina 1 into the tip side of the cylinder 2 into which A is inserted,
Furthermore, the filter body was filled with a transparent body 3 made of 8 my of glass wool at the rear of Spirulina 1.
47Ittt Spiruliso stomach under smoking conditions Before and after installing the cigarette filter, smoke 172 [tar, benzo(a) pyrene, nicotine, rl! This is a constant temperature test for carbon dioxide.

Test method> Standard *@Smoke conditions: Smoking volume 35 d/time, smoking time 2 seconds/time, smoking frequency 1 time/min, length of inhalation I ~ 30 ryrt.

Spirulina 5 (C9, transparent body (glass wool) 8mt
l, Iζ struck under these conditions.

■ Tar However, under standard smoking conditions, collect the cool in the mainstream smoke on a quartz fiber-paper and measure the m opening to determine the tar negative 1%-6 ■ Collect in benzo(a)pyrene ■ The collected tar on paper was diluted with benzene-ethanol (4:1 v/) and n-hekyrin methylene monochloride (65:35 v/) at °C.
■ The extracted sample was subjected to sonic extraction, and the extracted sample was made into an acetinitrile solution using a hot liquid chromatography fluorescence detector. was subjected to ultrasonic extraction using Ezil-Deru 1N methylene (1:1 V/), and the extracted sample was used as an n-propanol solution to determine nicotine by gas chromatography.

- Carbon oxide Carbon monoxide was determined by constant potential electrolysis under standard smoking conditions.

The above test results are shown in the table below.

LLI Song for this exam, Spirulina ￥! Smoke core (filter removes tar (3'1%
, benzo(a)pyrene 45%, nicotine 53%, -
Carbon oxide was found to have an average removal effect of 20%. Also, according to these results, the removal rate of tar and nicotine was particularly high among people who used chlorella (!) jj
In fact, it has been corrected that it is much higher than the 1972-22316″?i publication ;).

Moreover, Spirulina 1 itself can be collected by simply filtering water, and the technology for culturing Spirulina 1 has already been established.
It is possible to reduce the production cost in filter manufacturing using Spirulina 1. In addition, Spirulina 1 has already been used as feed for animals such as Fugaku, and has also been used as feed for humans.
Not only has its harmlessness been proven, but the thickness δ of Spirulina 1 alone ranges from microscopically small to visible with the naked eye. It is possible to use various sizes and number them depending on the mode of use. Therefore, since it can be widely applied to the material used for the transparent body 3, the Spirulina 1 contained therein can be completely held and fixed in the film, and the Spirulina 1 can be reliably prevented from being sucked into the mouth. , without impairing the taste of smoking.

As described above, according to the present invention, it is possible to effectively remove harmful vA substances such as tar and nicotine contained in the cooking process during smoking, and also without changing the taste during smoking. ,
Furthermore, it produces various industrially beneficial effects such as being able to keep production costs low.
