Description

Cigarette with filter

The present invention relates to a cigarette with a filter attached thereto.

Cigarettes are representative smoking articles that enjoy the aroma of tobacco leaves. In recent years, in response to the diversification of smokers, a sensory stimulant different from the scent imparted by tobacco silk is added to various parts of the cigarette. For example, Patent Document 1 discloses a technique of adding a cold sensitizer to a tip paper which is connected to a cigarette rod and a filter rod. The cold sensitizer added to the outer paper imparts a direct cold sensation to the lips of the smoker who is in direct contact with the outer paper when smoking, thereby allowing the smoker to feel a continuous refreshing feeling.

However, a cigarette with a filter attached to the outer layer of the sensory stimulant is used to transfer the sensory stimulant from the outer layer to other parts of the cigarette, especially the filter, resulting in a reduction in the amount of sensory stimulant on the outer sheet. . As a result, the sensory stimulation directly imparted to the smoker's lips is weakened.

It is therefore an object of the present invention to provide a filter-attached cigarette that necessarily inhibits the transfer of the sensory stimulator added to the outer layer to the filter.

The invention provides a cigarette with a filter, which comprises: a cigarette rod which is wrapped with tobacco paper into a stick shape; and is arranged on one end surface of the cigarette rod, and the filter material is wrapped into a rod by a filter paper roll. a filter rod having a shape; and coating the outer surface of the outer surface of the cigarette rod while covering the outer peripheral surface of the filter rod; wherein the outer paper is attached with a feeling stimulating agent, the filter paper roll It is a sensory irritant that is difficult to penetrate.

The cigarette with the filter of the present invention inevitably inhibits the transfer of the sensory stimulator added to the outer layer paper to the filter.

Hereinafter, various embodiments of the present invention will be described.

A cigarette with a filter according to an embodiment of the present invention includes a cigarette rod, a filter rod, and an outer layer paper. The cigarette rod is provided with a tobacco yarn and a cigarette paper in which the tobacco yarn is wrapped into a cigarette shape (usually a cylindrical shape). The filter rod has a filter material and a filter roll that wraps the filter material into a rod shape (usually a cylindrical shape). The filter rod is attached to one end of the cigarette rod by the outer paper. The outer paper is coated with a filter rod (more specifically, a filter roll paper) and peripherally coated with a cigarette rod (more specifically, a cigarette paper).

The tobacco yarn and cigarette paper constituting the cigarette rod are the same as the tobacco yarn and cigarette paper used in general cigarettes.

Although the outer layer paper is also the same as the outer layer paper used for the cigarette to which the filter is generally attached, in the present invention, the sensory stimulating agent is attached. In the case of a feeling stimulant, a cold sensitizer is preferred. The cold sensitizer can be selected, for example, from 3-1-1-menthoxypropane-1,2-diol, N-ethyl-p-menthane-3- N-ethyl-p-menthane-3-carboxamide, 3-1-1-menthoxy-2-methylpropane-1,2-diol (3-1-menthoxy-2-methyl propane-1) , 2-diol), menthol, menthone, camphor, pulegol, isopulegol, cineole, mint oil , peppermint oil, spearmint oil, eucalyptus oil, p-menthane-3,8-diol, 2-1-menthol 2-ephthyl-1-ol, 3-1-1-menthoxypropane-1-ol, 4-1-menthyloxy Butyr-1-butan-1-ol, menthyl 3-hydroxybutanoate, menthyl lactate, menthone glycerin acetal, 2 -(2-1-menthyloxyethyl)ethanol, menthyl glyoxylate, 1-(2-hydroxy-4-methylcycloethyl Ethyl ketone (1-(2-hydroxy-4-methylc) Yclohexyl)ethanone), N-methyl-2,2-isopropylmethyl-3-methylbutane amide, 2-pyrrolidone- Menthyl 2-pyrrolidone-5-carboxylate, 2-isopropyl-N-2,3-trimethylbutanamine 1,2-propanediol (2-isopropyl-N-2,3 -trimethylbutyramide 1,2-propane diol). A sensory stimulator such as a cold sensitizer can be applied to the outer layer of paper.

The filter material constituting the filter rod may be the same as the filter material used for the cigarette to which the filter is generally attached. The filter material contains a tow of cellulose acetate. The fiber bundle of cellulose acetate fibers may contain a plasticizer such as triacetin in a proportion of 5 to 10% by weight. However, the filter material is preferably a plasticizer free, that is, a free plasticizer. Plasticizers have a tendency to adsorb sensory stimuli and attenuate sensory stimuli. As the filter material containing no plasticizer, a fiber bundle, paper, or the like of cellulose acetate fibers (excluding a plasticizer) can be exemplified.

The filter roll paper constituting the filter rod with the filter material is impenetrable to the sensory stimulating agent, that is, it is difficult to permeate the sensory stimulating agent. In the case of a filter roll paper which is not easily permeable to a feeling stimulating agent, although a plastic film or a plastic film and a paper laminating paper may be considered, the gas permeability is not good, for example, 14 to 20 μm. A general laminated paper of a polyethylene layer is a case in which moisture is not easily permeable and the taste is changed as compared with a conventional cigarette. Further, although a conventional processing paper using a fluorine-based compound having oil resistance and water vapor permeability can be considered as an oil-resistant paper, it is not preferable for the global environment because it is hard to be decomposed. Thus, the filter roll paper used in the present invention is preferably a glassine and a tracing paper, parchment which is substantially water vapor permeable and environmentally friendly, although it does not penetrate the sensory irritant. Parchment) (sulphuric acid paper) and the like. In particular, it is preferred to use a base paper having a basis weight of 30 to 60 g/m ² and a water-soluble polymer substance coated on at least one side of the base paper, and exhibit an anti-wear resistance of 50,000 to 300,000 seconds. Oil-resistant paper with a gas permeability of 2,000 to 4,000 g/m ² ‧24 hrs as a filter roll paper. Such a paper is described in Japanese Patent No. 4520138, and is sold by Nippon Paper PAPYLIA Co., Ltd. According to Japanese Patent No. 4520138, the base paper of the oil-resistant paper is: the natural fiber of papermaking having a water filtration degree of 85 to 90° SR of Schopper contains a refraction of 2 to 10% by mass relative to the fiber. A filler of 1.8 to 3.0 and exhibits a gas permeability of 50,000 to 200,000 seconds. The polymer material may be selected from the group consisting of self-oxidized starch, organic phosphated starch, acetylated starch, unmodified starch, carboxymethylcellulose salt, and coated at a ratio of 0.2 to 1.0 g/m ² . On the base paper. In terms of coatings, the series includes rutile type titanium dioxide (refractive index of 2.76), anatase type titanium dioxide (refractive index of 2.52), zirconium (zircon) (refractive index of 2.40), Inorganic pigment such as zinc oxide (refractive index 2.01), titanium dioxide coated mica (refractive index 2.3), iron oxide coated mica (refractive index 2.9), titanium dioxide coated with silica, glass coated with titanium dioxide (glass) Fluke) and other composite pigments. These fillers are added in an amount of 2 to 10% by mass, preferably 3 to 7% by mass, to the natural fibers for papermaking.

The cigarette rod 110 is a case in which the tobacco yarn 111 is covered with a cigarette paper 112 in a rod shape (generally, a column shape). The filter rod 120 is formed by coating the filter material 121 such as a fiber bundle of cellulose acetate fibers into a rod shape (generally a columnar shape) with a filter roll 122, and has substantially the same diameter as the cigarette rod. The cigarette rod 110 and the filter rod 120 are in contact with each other at the end surface and the end surface, and are fixed by a layer paper 130 to which a feeling stimulating agent (not shown) is attached. The outer layer paper 130 covers the outer peripheral surface of the filter rod and partially covers the outer peripheral surface of the cigarette rod.

The invention is illustrated by the following examples, but the invention is not limited by the examples.

(Example)

A cigarette having the specifications shown in Table 1 below was prepared. The cigarette with the filter of the comparative example is a commercially available product. The cigarette of the present invention is such that only the filter paper or filter material used is different from the cigarette with the filter of the comparative example. The 50NFB used as the filter roll paper is an oil-resistant paper sold by Nippon Paper PAPYLIA Co., Ltd., and the basis weight (in the case of "pounds", the weight per unit area of the paper) is 35 g/m ^{2 .} According to JIS P-8117:2009, the air resistance is 130,000 seconds, according to the moisture permeability test method (Kap method) of the moisture-proof packaging material described in JIS Z0208-1976, at a temperature of 40 ± 0.5 ° C, relative humidity The moisture permeability measured under conditions of 90 ± 2% was 2,700 g/m ² ‧24 hr. P10000 is a general filter roll paper sold by Nippon Paper PAPYLIA Co., Ltd.

On the outer layer of three cigarettes A to C with filter, coated with cold sensitizer (N-ethyl-p-menthane-3-carboxamide) or (3-1-menthoxypropane- 1,2-diol), stored in a constant temperature chamber at 55 ° C for a predetermined period of time. Thereafter, the cold sensitizer remaining on the outer layer paper was taken out and quantified by the following method. The residual ratio (average value of the three branches) of the cold sensitizer when the amount of the initial addition of the cold sensitizer was 100% was calculated. The results are shown in Table 2 below.

(Extraction of cold sensitizer, quantitative method)

The outer layer paper was cut out from the cigarette with the filter attached thereto, and 10 ml of ethanol was added thereto, followed by shaking for 1 hour. The cold sensitizer contained in the extract after shaking was quantified by GC/MS.

As is apparent from the results shown in Table 2, in the filter-attached cigarette of the present invention, the residual ratio of the cold sensitizer is much higher than that of the cold sensitizer of the cigarette with the filter of the comparative example. Furthermore, when the material containing no plasticizer is used as the filter material, the above residual ratio is further improved.
