Description

Smoking items with filter

The present invention relates to smoking articles with filters.

Filter-attached smoking articles, for example, general filter-attached cigarettes are as follows: non-woven fabric containing cellulose acetate fiber or pulp is tied or folded to form a filter material, and the filter material is The filter wrapper is wrapped to form a rod-shaped filter, and the dried tobacco leaves are wrapped in cigarette paper to form a rod-shaped cigarette rod, and the filter is combined with the The cigarette stick is wrapped with tipping paper (also called outer layer paper) in a state where the ends are adjacent to each other, and the filter tip and the cigarette stick are bonded and integrated. At this time, the tipping paper is rolled around the filter side end of the cigarette stick and the filter tip, and connects the cigarette stick and the filter tip.

The tipping paper is the part of the mouth which is related to the taste of cigarettes with filters. Therefore, the whiteness that can create a sense of cleanliness is generally emphasized. Therefore, we reviewed the technique of decorating the base paper of white tipping paper to manufacture tipping paper. In this way, the decoration of the white tipping paper base paper includes gravure printing, holographic printing, foil printing, etc. By adopting a design that takes advantage of the whiteness of the base paper, it can give preference to cigarettes with filters. And pursue the differentiation of products (for example, Patent Documents 1 and 2).

On the other hand, there are also designs that use white base paper as a base to appeal for a natural feel. An easy-to-understand example includes cork printing (for example, Patent Document 3).

Patent Document 1: International Publication No. 2015/177907.

Patent Document 2: Japanese Special Publication No. 2016-508377.

Patent Document 3: Japanese Patent No. 4191273.

In addition to white tipping paper, tipping paper that can effectively impart preferences to cigarettes with filters is, for example, tipping paper with a clean and natural appearance. Although cork printing is now a widely used design, it is only imitated and still has an artificial feel. Even if you want to improve the texture and pursue design other than cork printing, after all, it is only a pattern made by repeating "the pattern engraved on the intaglio cylinder is irregular at first glance but is actually a regular pattern." The combination of so far white base paper and printing is difficult to create a sense of naturalness and naturalness.

The subject of the present invention is to provide a smoking article with a filter, which contains a textured tipping paper, which can create a natural feeling that cannot be achieved by printing.

According to the present invention, a smoking article with filter can be provided The product is equipped with: aerosol (also known as aerosol) generating rod; a filter, which is arranged at the downstream end of the mist generating rod; and a tipping paper, which is wrapped around the downstream end of the mist generating rod and the filter tip The outer peripheral surface is connected with a mist generating rod and a filter; wherein the tipping paper is paper containing bleached pulp and unbleached pulp, and the fibers of unbleached pulp have a length of 1mm to 4mm and a thickness of 20μm to 70μm.

As far as smoking articles are concerned, in addition to cigarettes, there are also smoking articles such as cigars or cigarillos, which are produced by burning the tip of a mist generating rod including a cigarette stick to generate smoke. In addition, smoking articles also include "a form in which a mist generating rod containing a cigarette stick is heated without burning to generate flavor components." The method of heating without burning is a method of heating by resistance, IH, chemical change or phase change, etc.

As described above, the mist generating rod includes a cigarette rod in which dried tobacco leaves are wrapped in cigarette paper and formed into a rod shape. In addition, it also includes: a method of wrapping dried tobacco leaves with tobacco sheets; and a method of impregnating a substrate other than the tobacco leaves with a mist source such as glycerin and flavor components, and wrapping the substrate in paper to form a stick. In either form, the mist generating rod is slightly cylindrical, and the filter is butted at one end and connected by a tipping paper roll.

According to the present invention, it is possible to impart a natural feeling and preference to a smoking article with a filter.

Several embodiments will be described below with reference to the drawings. The same components in the embodiment are given the same symbols and repeated descriptions are omitted. In addition, each drawing is a schematic diagram for understanding the embodiment, and its shape, size, ratio, etc. are different from the actual situation. The terms "upstream" and "downstream" are suitable for use in this manual, which are based on the flow direction of mainstream cigarettes when smoking articles with filters.

In the following embodiment, an example of a cigarette with a filter as a smoking article with a filter is described.

(First Embodiment)

Fig. 1 is a schematic perspective view of the cigarette with filter 1 according to the first embodiment. Figure 2 is a schematic cross-sectional view showing an enlarged cross-section along the line II-II in Figure 1. The cigarette 1 with a filter includes a mist generating rod 11, a filter 12, and a tipping paper 13.

The mist generating rod 11 is composed of, for example, "tobacco filaments 111 containing dried tobacco leaves" and "cigarette paper 112 around rolled tobacco filaments 111", and has a substantially cylindrical shape. The cigarette paper 112 is, for example, paper having air permeability.

The filter 12 is arranged at the downstream end of the mist generating rod 11. The filter 12 has the same or almost the same diameter as the mist generating rod 11. The filter 12 is composed of a "filter material 121" and a "filter covering material 122 around the roll filter material 121". The filter 12 is composed of a single filter material, that is, has a plain filter structure.

The filter material 121 is, for example, formed by "binding or folding a non-woven fabric of cellulose acetate fiber or pulp".

The filter covering material 122 is, for example, paper with a base weight of 15 gsm to 100 gsm and a thickness of 30 μm to 100 μm. The air permeability of this paper is 0C.U. to 30000C.U. The air permeability is a value measured in accordance with ISO 2965:2009, which is expressed as a gas flow rate (cm ^{3 ) passing through an area of 1 cm 2 per minute when the pressure difference between the two sides of the paper is 1 kPa.} 1 Coresta unit (1C.U.) is cm ³ /(min.cm ² ) under 1kPa.

The tipping paper 13 is wound around the downstream end of the mist generating rod 11 and the outer peripheral surface of the filter 12, and is connected to the mist generating rod 11 and the filter 12. The tipping paper 13 connects the mist generating rod 11 and the filter 12 with an adhesive such as a paste. In addition, the tipping paper 13 is a paper containing bleached pulp and unbleached pulp.

Unbleached pulp is unbleached colored pulp. The fibers of unbleached pulp have a length of 1 mm to 4 mm and a thickness of 20 μm to 70 μm, preferably a length of 2 mm to 4 mm and a thickness of 30 μm to 70 μm. When the unbleached pulp fibers contained in the tipping paper 13 have a length of 1 mm to 4 mm and a thickness of 20 μm to 70 μm, the smoker can visually confirm the presence of unbleached pulp on the outer peripheral surface of the tipping paper 13. therefore, When the tipping paper 13 contains "fibers of unbleached pulp with a length of 1 mm to 4 mm and a thickness of 20 μm to 70 μm", the filter-attached cigarette 1 provided with the tipping paper 13 can allow the smoker to visually confirm the natural feel.

The length and thickness of the fibers of the unbleached pulp contained in the tipping paper 13 are observed using a microscope at a magnification of 100 times or less, and the attached ruler is used to measure about 50 visible colored fibers. Thickness and length.

The proportion of unbleached pulp contained in the tipping paper 13 is, for example, preferably 1% by weight or more and 90% by weight or less, more preferably 5% by weight or more and less than 86% by weight, and still more preferably 5% by weight or more. 60% by weight or less. The tipping paper 13 used in the embodiment contains bleached pulp and unbleached pulp. Therefore, compared to a tipping paper composed of only bleached pulp, the use of bleaching agents can be reduced during manufacture and the environmental load can be reduced.

Bleached pulp is pulp that has been bleached by using bleaching agents such as oxidizing agents and reducing agents. The length and thickness of the fibers of the bleached pulp can be the same as or different from the length and thickness of the unbleached pulp, and there is no particular limitation.

In addition, the tipping paper 13 preferably has a lightness L* of 78 to 93, a chromaticity a* of 0.6 to 2.8, and a chromaticity b* of 7 to 18 in the CIELab color system. The lightness L*, chromaticity a*, and chromaticity b* in the CIELab color system of the tipping paper 13 can be measured using a spectrophotometer (manufactured by X-Rite, product name SpectroEye). More preferably, the CIELab color system of the tipping paper 13 is a lightness L* of 80 to 92.5, a chromaticity a* of 0.7 to 1.6, and a chromaticity b* of 8 to 13. The lightness L*, chroma a*, and chroma b* of the CIELab color system of tipping paper 13 can be adjusted by adjusting the types of bleached pulp and unbleached pulp, and the content of unbleached pulp. control. In addition, even if the lightness L* in the CIELab color system of the tipping paper is 78 to 93, the color a* is 0.6 to 2.8, and the color b* is within the range of 7 to 18, when the tipping paper does not contain " If there are fibers of unbleached pulp with a length of 1mm to 4mm and a thickness of 20μm to 70μm, the tipping paper will only be colored paper. Therefore, it is difficult for the smoker to visually confirm the naturalness of a cigarette with a filter containing the tipping paper.

Wood pulp can be used for bleaching pulp. Unbleached pulp can use wood pulp or non-wood pulp.

The type of wood used as the raw material of the wood pulp is not particularly limited, and preferably are: Japanese cedar, Japanese cypress, pine, Japanese fir, cypress and other coniferous trees; Eucalyptus, beech, oak, poplar and other broad-leaved trees.

For wood pulp, for example, the above-mentioned wood can be used to remove impurities or lignin from the raw wood by a chemical treatment such as the Kraft process (Kraft process) to remove impurities or lignin, and then perform a bleaching step and a washing step to produce wood pulp. In this way, wood pulp produced by the kraft pulp method, also known as kraft pulp or chemical pulp, has high flexibility and less impurities, so it is better to use it as a bleached pulp.

In addition, for wood pulp, for example, the above-mentioned wood can be used to remove impurities or lignin from the raw wood in a steaming step, and then perform a bleaching step in a short time or not at all, and perform a washing step, thereby manufacturing wood pulp. The wood pulp produced in this way has fibers of the above-mentioned length and thickness, so it can be used as unbleached pulp.

Unbleached pulp may contain, for example, non-wood pulp. The type of non-wood used as the raw material of non-wood pulp is not particularly limited, and it is preferably large Hemp, kenaf, flax, rice straw, wheat straw, etc.

In the non-wood pulp, in addition to the above-mentioned fibers having a preferred length and thickness, fibers and spot-like lumps, etc., that exceed the preferred length and thickness may sometimes be contained. In the tipping paper containing such unfavorable fibers and blocks, the fibers or blocks will be regarded as foreign matter in appearance, and a cigarette with a filter tip provided with the tipping paper may be impaired and high preference. Therefore, although unbleached pulp may also contain non-wood pulp, it is preferable to contain more wood pulp, and more preferably only wood pulp.

The tipping paper 13 may further contain calcium carbonate or titanium oxide, which is a filler, and may be paper with an opacity of more than 76%. The tipping paper 13 with an opacity of more than 76% can be obtained by, for example, containing more than 20% by weight of calcium carbonate. In the tipping paper 13 with an opacity of more than 76%, the characters and graphics printed on the surface are difficult to penetrate to the inner surface, so it is preferable.

The filler is, for example, mineral powder formulated in paper, including inorganic or organic compounds. In terms of fillers, in addition to calcium carbonate, it also includes titanium oxide, calcined kaolin, kaolin, talc, acid clay, aluminum hydroxide, or synthetic silica. In addition to calcium carbonate and titanium oxide, the tipping paper 13 may contain one or more other fillers. By containing the above-mentioned filler in the tipping paper 13, it is possible to impart flame retardancy to the tipping paper without impairing and visually confirming the appearance of the fibers of the unbleached pulp of the tipping paper. For example, by containing kaolin and aluminum hydroxide in the tipping paper 13, flame retardancy can be imparted to the tipping paper.

In addition, a hydrophobic coating is formed on the surface of the base web containing "wood pulp, fillers, calcium carbonate, and wet paper strength enhancer". The tipping paper of the cloth layer can impart excellent water resistance.

Examples of the wet paper strength enhancer include polyamide epichlorohydrin (PAE), polyethyleneimine, epoxidized polyamide, and polypropylene amide.

Examples of hydrophobic coating agents include nitrocellulose (NC), colored hydrophobic inks containing pigments suitable for gravure printing, and the like.

The tipping paper 13 preferably has a tensile strength of, for example, 26.0 N/15 mm or more. The tipping paper 13 with a tensile strength of 26.0N/15mm or more can ensure the sufficient strength required for high-speed cigarette manufacturing. Therefore, when cigarettes are manufactured at a high speed, the tipping paper can be prevented or reduced from being injured or broken during the movement of each device.

As for the tipping paper 13, when the surface is rough, the characters or patterns printed on the surface are likely to lack white, but the lack of white characters or patterns can increase the natural feeling. On the other hand, tipping paper with a smooth surface can print clear text or patterns on the surface without compromising the natural feel. Therefore, the tipping paper 13 can have a smoothness in a wide range of 5 sec or more and 300 sec or less. In addition, when the tipping paper 13 is printed, environment-compatible inks, such as vegetable oil inks, can be used.

For example, the above-mentioned tipping paper can be manufactured by the following method.

First, prepare cypress which belongs to coniferous tree and poplar which belong to broad-leaved tree as bleached pulp, and prepare pine tree as unbleached pulp. Put the desired ratio of bleached pulp and unbleached pulp into a pulper to dissociate the pulp. Then, move the dissociated pulp to refined Machine (refiner), and percussion with a refiner. In addition, calcium carbonate as a filler and a flocculant as a manufacturing aid are prepared, and these are mixed with the percussed pulp. In addition, multiple beaters can be used to separately dissociate bleached pulp and unbleached pulp, and the refiner can be used to decompose. The bleached pulp and unbleached pulp, fillers, and manufacturing aids are mixed in a mixing box.

Next, using this mixed pulp, in a papermaking step performed by a Fourdrinier paper machine, a cylinder paper machine, a round and short composite paper machine, etc., the texture is sorted and homogenized to produce tipping paper. In addition, in the papermaking step, penetration inhibitors such as alkyl ketene dimer (AKD) can be added to adjust the printing conditions of the tipping paper, or a wet paper strength agent can be added to the tipping paper Imparts water resistance.

(Second Embodiment)

Fig. 3 is a schematic cross-sectional view showing an enlarged part of the cigarette with filter 2 of the second embodiment. The cigarette 2 with a filter of the second embodiment has the same structure as the cigarette 1 with a filter of the first embodiment, except that a varnish 14 is present on the outer peripheral side of the tipping paper 13.

The varnish 14 penetrates into the mouthpiece paper 13 and also exists inside the mouthpiece paper 13. For the varnish system, for example, nitrocellulose, ethyl cellulose, carboxymethyl cellulose, etc. can be used.

Since the cigarette with filter 2 has a varnish 14 on the outer peripheral side of the tipping paper 13, in addition to the effects described in the first embodiment, the unbleached pulp derived from the tipping paper 13 can also be suppressed or prevented. Lignin Or other impurities caused the flavor to decrease. In addition, since the filter-attached cigarette 2 has a varnish 14 on the outer peripheral side of the tipping paper 13, the lip separation of the tipping paper 13 when the filter-attached cigarette 2 is smoked can be improved.

In addition, the filter-attached cigarettes of the respective embodiments described above may be provided with other configurations. For example, a plurality of holes (vent holes) penetrating the tipping paper to the filter tip may be provided. Such vents have the function of supplying air from the outside into the filter.

In addition, the shape of the filter can be a dual filter, a triple filter, or the like.
