Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cigarette, a cigarette package, and a cigarette filter.
In the present invention, a cigarette refers to one cigarette, and a cigarette package refers to a package in which a plurality of cigarettes are stored and packed.

[0002]

2. Description of the Related Art Cigarettes have a filter at their mouth as a means for adsorbing tar, nicotine and the like generated during smoking. As is well known, this filter portion is made of synthetic fiber synthesized from petroleum as a raw material. The filter unit is generally formed by accumulating chemical fibers as a means for increasing the efficiency of adsorbing harmful components, and there is also a filter unit in which activated carbon or the like is charged. Specific examples of the chemical fiber include vinyl chloride, polychlorinated biphenyl, vinylidene chloride, polyethylene, and polypropylene.

[0003] When the cigarette has been smoked, a cigarette butt including the filter portion of the mouthpiece remains. This butt is usually incinerated as burning garbage. However, in conventional cigarettes, since the filter at the mouth portion is made of synthetic fiber synthesized from petroleum as a raw material, if the butts are incinerated, harmful gas is generated, which causes severe environmental destruction and sanitary pollution. Invite.

For example, dioxin is generated from a filter composed of vinyl chloride, polyvinyl chloride, polyvinylidene chloride, or the like. Dioxin is
It is the strongest toxic component encountered by humans and has extremely strong carcinogenic properties. Also, as shown by the effects of defoliants in the Vietnam War, humans and animals and plants are severely damaged or adversely affected even at the genetic level.

[0005] In addition, filters made of polyethylene, polypropylene and the like produce nitrogen oxides (N ₂ ) such as nitrogen dioxide (NO ₂ ) and nitric oxide (NO).
O _X) is generated. These nitrogen oxides are representative air pollutants and lead to global warming.

[0006] For this reason, prevention of generation and generation of harmful gases such as dioxins and nitrogen oxides is now a common issue throughout the world.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to provide a cigarette capable of suppressing the generation of harmful gases such as dioxins and nitrogen oxides to an extremely small amount when incinerated.
An object of the present invention is to provide a cigarette package and a cigarette filter.

[0008]

Means for Solving the Problems In order to solve the above-mentioned problems, in the cigarette according to the present invention, the filter portion is made of plant fiber, plant starch, animal fiber or a combination thereof.

[0009] In the cigarette according to the present invention, the filter at the mouth portion is prepared by processing plant fiber and plant starch;
Because it is made from animal fiber or a combination of these,
Even when the butts are incinerated, almost no harmful components such as dioxin and nitrogen oxides are generated.

[0010] Further, since the filter portion remaining as cigarette butt is made of plant fiber, plant starch, animal fiber or a combination thereof, it is surely treated by underground bacteria when buried in the ground upon disposal. Decomposed. Therefore, not only harmful gases such as dioxins and nitrogen oxides but also carbon dioxide are not generated.

The cigarette filter according to the present invention is used by being attached to a mouthpiece of a cigarette, and is configured as a member independent of the cigarette, a so-called pipe.

Other objects, configurations and advantages of the present invention will be described in more detail with reference to the accompanying drawings which are embodiments.

[0013]

FIG. 1 is a sectional view of a cigarette according to the present invention. The illustrated cigarette has a cigarette part 1, a filter part 2 and a wrapper part 3. The filter unit 2
This is the part corresponding to the mouthpiece. The present invention is characterized in that the filter portion 2 is composed mainly of plant fiber, processed plant starch, animal fiber or a combination thereof.

The filter section 2 is made of a first material charged with activated carbon or the like.
And the second filter unit 22 are arranged in series. Both the first filter unit 21 and the second filter unit 22 use plant fiber, plant starch, animal fiber, or a combination thereof as a raw material.
Although not shown, the first filter section 21 may not be charged with activated carbon or the like.

[0015] Plant fibers include fibers obtained from cotton, hemp, kenaf, bamboo or wood. In the filter section, these raw materials may be configured as a bundle of fibers, or may be formed by accumulating finely crushed materials. Vegetable fibers that are readily available and effective for adsorbing components contained in smoke are cotton and hemp fibers.

[0016] Plant starch includes corn, wheat,
Includes starch obtained from rice, soybeans or various potatoes. The filter portion may be made of a foamed material using these materials as a foam, or may be made into a fibrous shape to be a bundle of fibers.

Animal fibers include fibers obtained from domestic animals such as sheep, goats, rabbits, cows and horses, fibers obtained from bird feathers, fibers obtained from wild animal hair, and silk yarns. And so on. The filter unit may be configured by using these materials as a bundle of fibers, or may be formed by accumulating finely crushed materials. Animal fibers that are readily available and effective for adsorbing components contained in smoke are fibers and silks obtained from wool.

The above-mentioned plant fiber, plant starch and animal fiber may be used alone or in combination with each other.

In the cigarette according to the present invention, since the filter part 2 of the mouth part is made of plant fiber, plant starch, animal fiber or a combination thereof, even if the butts are incinerated, dioxin, nitrogen oxide, etc. Almost no harmful components are generated.

Moreover, since the filter portion 2 remaining as a cigarette butt is made of plant fiber, plant starch, animal fiber or a combination thereof, the filter portion 2 can be reliably disposed of when buried in the ground by underground bacteria or the like. Is decomposed into

Although not shown, in the actual sales form, for example, 10 cigarettes or 20 cigarettes described above are used.
A cigarette package in which books are stored in one package.

Although not shown, the filter section may be independent of the cigarette, and may be configured as a pipe detachable from the cigarette. In this case, the main body of the pipe containing the filter portion of the plant fiber, the plant starch or the animal fiber is made of a combustible material that is a non-petroleum product.

[0023]

As described above, according to the present invention,
When incinerated, it is possible to provide a cigarette, a cigarette package, and a cigarette filter capable of suppressing the generation of dioxin and nitrogen oxide to an extremely small amount of almost zero.
