[0001]

The present invention relates to a cigarette and a filter for a cigarette.

[0002]

2. Description of the Related Art Conventionally, as a filter for cigarettes, a filter mixed with activated carbon (charcoal) powder is known. However, conventional filters containing activated carbon have a structure in which activated carbon powder is mixed into fibers such as cotton, which is the main component of the filter, and thus effectively absorb harmful substances generated when burning tobacco. There is a problem that you can not.

[0003]

The present invention can effectively absorb harmful substances generated when burning tobacco,
An object of the present invention is to provide a cigarette that can reduce adverse effects on the human body.

[0004] It is an object of the present invention to provide a tobacco filter capable of effectively adsorbing harmful substances generated when burning tobacco and reducing adverse effects on the human body.

According to a first aspect of the present invention, there is provided a cigarette in which tobacco leaves are wrapped by a wrapping paper, wherein the wrapping paper is mixed with powdered bamboo charcoal.

A second cigarette according to the present invention is characterized in that, in a tobacco in which tobacco leaves are wrapped by wrapping paper, powdery bamboo charcoal is attached to the tobacco leaves.

According to a third aspect of the present invention, there is provided a cigarette in which tobacco leaves are wrapped by wrapping paper. Features.

In the first to third cigarettes, at one end,
It is preferable to provide a filter including a fiber layer portion at both ends made of fibers and a bamboo charcoal layer portion provided between the two fiber layer portions and hardened with powdery bamboo charcoal.

A cigarette filter according to the present invention is a cigarette filter comprising a fiber layer portion at both ends made of fibers, and a bamboo charcoal layer portion provided between the two fiber layers and formed by solidifying powdery bamboo charcoal. It is characterized by having.

Embodiments of the present invention will be described below with reference to the drawings.

[1] Description of First Embodiment

FIG. 1 shows the structure of a cigarette with a filter.

The cigarette with a filter comprises a cigarette body 1 and a filter 2 attached to one end of the cigarette body 1. The cigarette body 1 includes a wrapping paper portion 11 and a tobacco leaf 12 wrapped around the wrapping paper portion 11.

As the wrapping paper section 11, a wrapping paper in which fine bamboo charcoal is mixed is used. The wrapping paper section 11 is made, for example, by mixing fine powdered bamboo charcoal in a liquid paper raw material with 0.01 g per cigarette, rinsing the mixed liquid, and winding it into a roll.

In this cigarette, the bamboo charcoal contained in the wrapping paper 11 adsorbs the harmful substances generated when the cigarette burns, so that the harmful substances generated when the cigarette burns turn into ash to the human body. It is prevented from being sucked. When the bamboo charcoal contained in the wrapping paper section 11 burns, harmful substances generated when the cigarette burns are adsorbed, but no smoke is generated even if the bamboo charcoal burns.

[2] Description of Second Embodiment

FIG. 2 shows the structure of a cigarette with a filter.

The tobacco with a filter is a cigarette main body 101.
And a filter 102 attached to one end of the cigarette body 101. The cigarette body 101 includes a wrapping paper 111.
And a tobacco leaf portion 112 wound around the wrapping paper 111.

As the tobacco leaf part 112, a tobacco leaf to which fine bamboo charcoal is attached is used. That is,
By kneading the tobacco leaves and the fine bamboo charcoal, for example, 0.05 g of fine bamboo charcoal per cigarette is adhered to the tobacco leaf, and the tobacco leaf to which the fine bamboo charcoal is adhered is rolled up with the wrapping paper 111.

More specifically, for example, kneading pulverized bamboo charcoal with a humidity of 25% and tobacco leaves with a humidity of 27% gives 2%
Due to the humidity difference, fine bamboo charcoal adheres to tobacco leaves. With the fine bamboo charcoal attached to the tobacco leaf, the tobacco leaf is rolled up with a wrapping paper 111. For example, 0.05 g of fine bamboo charcoal is attached to tobacco leaves per cigarette.

In this cigarette, bamboo charcoal contained in the tobacco leaf portion 112 adsorbs harmful substances generated when the tobacco burns, so that the harmful substances generated when the tobacco burns turn into ash. Suction is prevented. When the bamboo charcoal contained in the tobacco leaf portion 112 burns, harmful substances generated when the cigarette burns are adsorbed, but no smoke is generated even if the bamboo charcoal burns.

[3] Description of Third Embodiment

FIG. 3 shows the structure of a cigarette with a filter.

The cigarette with a filter is a cigarette main body 201.
And a filter 202 attached to one end of the cigarette body 201. The cigarette body 201 includes a wrapping paper 211.
And a tobacco leaf 212 wrapped around the wrapping paper 211.

The filter 202 has fiber layer portions 221 and 223 at both ends made of a fiber such as cotton, and both fiber layer portions 221 and 223.
23 and a bamboo charcoal layer 222 formed by hardening fine powder bamboo charcoal. The amount of fine bamboo charcoal in the bamboo charcoal layer part 222 is, for example, 0.02 g per cigarette. The length of each of the fiber layers 221 and 223 is, for example, about 9 mm, and the length of the bamboo charcoal layer 222 is about 6 mm.

When the tobacco is burned, the smoke is emitted from the tobacco main body 20.
1 through the filter 202 and is sucked into the human body.
Since the harmful substances contained in the smoke are efficiently adsorbed to the bamboo charcoal layer 222 in the filter 202, the harmful substances generated when the cigarette is burned are prevented from becoming ash and being sucked into the human body. You.
