DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cigarette filter and a cigarette with a filter.

[0002]

2. Description of the Related Art Most cigarette products currently on the market have a tobacco column section made of a cigarette-wrapped wrapping paper and a filter section made of a filter wrapped in a tissue paper. It is attached to one end of the column section with attachment paper. A cigarette filter is usually composed of a fiber bundle in which a fibrous filter material is bound by a binder. As the fibrous filter material, pulp, cellulose-based fiber such as cellulose acetate, or the like is used.

When such a cigarette with a filter is placed in an outdoor environment, papers are peeled off by rainwater, snowmelt, or the like, and the cigarette and the filter are exposed. In this case, the paper and tobacco shreds develop and come into contact with the soil and can be degraded by microorganisms in the soil. However, since the filter is made of a fibrous material bound by a binder, it cannot be developed by rainwater or the like, and even if it is a material that can be decomposed by soil microorganisms, the whole filter is sufficiently provided for the action of soil microorganisms. In many cases, the filter remains intact even after parts other than the filter are decomposed by soil microorganisms.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to release the binding of the fibrous material by the binder in the cigarette filter relatively easily and to physically deploy it when placed in an outdoor environment. It is an object to provide a means of:

[0005]

Means for Solving the Problems The present inventors have focused on the fact that the force of the germinating root when the seeds of the plant germinate and grows is strong enough to break through asphalt, and constructs a filter. By storing the seeds in the fiber bundle,
The present inventors have found that the binding of the filter fiber bundle by the binder can be released by using the germination root of the seed and the elongation and growth power of the cotyledon, and the fiber bundle can be physically developed, and the present invention has been completed.

That is, the present invention provides a filter body containing a fiber bundle bound by a binder, and a fiber bundle bundled in the filter body, which is released by germination to physically unfold the fiber bundle. An object of the present invention is to provide a cigarette filter comprising seeds.
The present invention also provides a cigarette with a filter, in which the filter is attached to one end of a tobacco column filled with tobacco cuts.

Hereinafter, the present invention will be described in more detail. The filter for cigarette of the present invention, in a normal filter body composed of fiber bundles bound by a binder,
The seeds are housed.

The seed used in the present invention may be any seed. For example, the following plant Niwazekishou (Si
syrinshium atlanticum ), communis ( Commelia commu )
nis ), Barley ( Bromus catharticus ), Poa annua , Azegaya ( Leptochloa chinens )
is ), Ohishiba ( Eleusine indica ), Miscanthus ( Miscun )
Thus sinensis ), Chinese primrose ( Sciaphilia japonic )
a ), Japanese pine (Sciaphilia tosaensis ), Japanese pine ( Chionographis japonica ), Cyperus ( Cyperus ( Cyperus haspan )), Orchardgrass ( Dactylis glomerata )
, Oilseed rape ( Brassica campestris ), hen ( Lamium amplexicaule ), dandelion
( Taraxacumofficinale ), white clover (white clover) ( Torifolium repens ), astragalus
( Astragalus sinicus ), Solidago ( Soli )
dago altissima ), sesame ( Sesamum indicum ), tobacco
( Nicotiana tabacum ), millet ( Setaria italica ),
Thyme ( Thymus valgaris ), sage ( Salvia officin )
alis ) and radish ( Raphanus sativas ) seeds, but are not limited thereto. However, it is preferable that the seeds do not impair the flavor and taste of ordinary cigarettes with a filter. For this purpose, so-called oil seeds having a high oil content are not preferable.

The size of the seed is preferably such that the smoke absorption of the smoke from the tobacco column is not reduced. In a filter having a normal filter size, the seed preferably has a maximum diameter of 2 mm or less. .

The seeds used in the present invention germinate under outdoor environmental conditions. However, it does not germinate under normal cigarette storage conditions. For seed germination,
Although water is an essential condition, the water is supplied when the filter of the present invention is placed in an outdoor environment, for example, by rainwater, snowmelt, or the like. Can be supplied).

Germination conditions other than water include oxygen, temperature,
There are light and the like, which are conditions that are usually satisfied if the filter is placed in an outdoor environment. The germination of some seeds can be affected by light and / or temperature. For example, seeds that have a habit of germination in a light place (light germinated seeds)
In the dark, germination is inhibited. However, even with such seeds, when treated with gibberellin,
Germination is promoted, so that it can be used in the present invention by gibberellin treatment as necessary. More specifically, in varieties such as chisha and tobacco, which have considerably strong photophobic properties, after absorbing water to a certain extent, they do not germinate unless irradiated with red light or white light, but if treated with an appropriate concentration of gibberellin, Almost complete germination can be expected even in the dark. The germination promoting effect of gibberellin is exerted even when seeds are treated with a compound that suppresses germination, such as coumarin, caffeic acid, and ferulic acid. In addition, the germination promoting effect of gibberellin does not disappear even by infrared irradiation having a germination suppressing effect. That is, when irradiating infrared rays immediately after irradiating red light to photosensitive seeds such as chisha and tobacco after water absorption to promote germination, germination promotion action by the red light is lost, but germination does not occur, but treatment with gibberellin was performed. After water absorption, the seeds germinate even when irradiated with infrared light immediately after irradiation with red light. Furthermore, potassium nitrate and ammonium nitrate further increase the germination promoting action of light and gibberellin. On the other hand, seeds that have a habit of germination in the dark place (dark germinated seeds) can also be used in the present invention, for example, by appropriately selecting seeds according to the temperature of the outdoor environment. More specifically, Hazetsurisou genus (Phacel
ia ) and Phlox germinate at low temperatures in both light and dark. It is known that seeds of these genera become typical dark germinated seeds at 21 to 24 ° C, and do not germinate at 31 ° C in either light or dark. Also, the temperature suitable for germination differs depending on the type of seed, but the seed has high resistance to temperature change, and can germinate even when exposed to low or high temperatures if it reaches a temperature at which it can germinate. The dark germinating seeds in addition to the above, Kurotanesou genus (Nigell
a ), Amaranthus , Celosia
, Cucurbitaceae ( Makuwauri , cucumber, pumpkin), Cyclamen ( Cyclamen europeaum ), Hothenosa ( Lamium )
amplexicaule ).

[0012] In addition, germination depends on the year and temperature of seed collection.
It may be more affected, but such seeds
Select seeds appropriately according to outdoor environmental conditions, etc.
Can be used in the present invention. For example,
Crabgrass (Digitaria ischaemumas well asD. sanguinali
s) Fresh seeds at an unsuitable temperature of 15-25 ° C
Shows only 2% germination 56 days after placement
However, for seeds that are 2 years old, 8% over the same period, 3 years old
It is known that seeds show a germination rate of 97%. Sa
In addition, these seeds are subjected to the advantageous
It is known that fresh seeds also have a high germination rate
You. Also, oilseed rape (Brassica campestris) Means seeding
Seeds within the next two years show high germination at room temperature, but 32
Above ℃, the germination was very low, above 38 ℃
Seeds that do not germinate well after 2 years
Germinates easily and germinates efficiently even at 38 ° C
Have been. As described above, the germination rate is increased by post-ripening.
Although some seeds rise, the germination rate increases with age.
Some seeds are degraded. Seeds used in the present invention
It can be appropriately selected in consideration of conditions and the like.

The filter body of the present invention comprises a fiber bundle formed by binding a fibrous material with a binder, similarly to a normal cigarette filter. As the fibrous material, it is preferable to use, for example, a cellulosic fiber such as cellulose acetate, pulp nonwoven fabric, paper and the like which can be relatively easily decomposed by soil microorganisms. As the binder, for example, triacetin, triethylene glycol diacetate, triethylene glycol dipropionate, dibutyl phthalate, dimethoxyethyl phthalate, and triethyl citrate can be used. Further, in the filter body, a flavor reducing agent such as activated carbon may be added similarly to a normal cigarette filter.

The number and position of the seeds to be accommodated in the filter body can be appropriately selected according to the size of the seeds. For example, among the seeds having a maximum diameter of 2 mm or less, about two large seeds are sufficient, and it is preferable that the seeds be accommodated in the center of the filter body. In addition, a large number of small particles in the above range can be accommodated, and it is preferable to disperse and accommodate them in the filter. If the filter body consists of two or more parts, such as a charcoal filter and a plain filter, each filter part contains an appropriate number of seeds according to the size of the seeds, as described above. Is preferred. In general, the number of seeds is preferably two or more than one. This is similar to the fact that planting two or more seeds of a plant in the case of pot planting is easier to germinate than one seed.

For accommodating the seeds in the filter body, a method of accommodating the seeds at an appropriate stage in the production stage of the filter body can be used, for example, according to the method of adding activated carbon as a flavor-mitigating agent to the filter. . In this case, by storing a large number of small seeds in the filter body, the seeds can be dispersed and stored in the entire filter, so that the yield of the filter of the present invention can be improved.

The cigarette with a filter of the present invention can be obtained by enclosing the filter of the present invention with thin paper on one end of a tobacco column made of a cylindrical wrapper filled with tobacco cuts, and attaching the filter with a mounting paper in a usual manner. . The cigarette with a filter of the present invention can have the same appearance as a normal cigarette with a filter except for the presence of seeds.

[0017]

When the cigarette with a filter of the present invention is placed in an outdoor environment, the attached paper and the thin paper are peeled off by rainwater, snowmelt, etc., and the filter body is exposed. Then, regardless of whether or not the cigarette is smoked, the seeds in the filter main body germinate under the influence of the outdoor environmental conditions, and the fiber bundles are released by the germination roots and cotyledons growing and elongating, and physically deployed. That is, at least a part of the bond by the binder is cut, and the original shape of the filter body formed by the fiber bundle collapses to the extent that the fibers inside the fiber bundle are also exposed,
When the fibrous material can be decomposed by soil microorganisms, the entirety thereof is sufficiently provided for the decomposing action of soil microorganisms. In addition, since the substance which forms it is a colloid (colloid), a seed absorbs water and expands. The amount of water absorption varies from seed to seed, but in many cases it is several times the seed weight. Therefore, for example, even when water is supplied to the seeds only temporarily, such as by rainwater, water can be retained in the seeds and germinated.

The filter body physically unfolded in this way, that is, the unbound fibrous material is not hindered in its original microbial degradability, that is, the same fibrous material not bound by the binder is removed from the soil. Can be degraded to the same extent as that of microorganisms. Organic substances and the like in the filter body act as nutrients for germinated roots and promote elongation and growth. In addition, depending on the type of seed, the rhizosphere is actively formed, and organic acids or plant hormones secreted from plant roots are abundant in the rhizosphere, thereby promoting the growth of rhizosphere microorganisms and promoting the decomposition of fibrous materials. I do. In addition, it was found that seeds germinated early if the filter was rubbed with a finger before being placed in outdoor conditions. This may be because a space is created between the seed and the fiber of the filter body, and the seed surface is damaged by contact between the seeds.
