Special table 2014-532433 gazette

  Since cellophane has high moisture absorption and desorption properties, it is necessary to coat the surface with varnish or the like in order to use it as chip paper. However, if the surface of the chip paper made of cellophane is coated with varnish etc., the adhesiveness with the adhesive for adhering the chip paper to the cigarette with filter will be reduced, and the chip paper will be easily peeled off from the cigarette rod or filter. It becomes difficult to manufacture the attached cigarette.

  In addition, since cellophane has low ink fixability, when cellophane is used as chip paper, it is difficult to print on the surface.

  Furthermore, cellophane has a plastic-like feel unlike paper used as ordinary chip paper. Therefore, if a cigarette with a filter using cellophane as a tip paper is smoked, the smoker may feel uncomfortable when the lip or tongue of the smoker touches the tip paper.

  An object of the present invention is to provide a cigarette with a filter in which the problems of the conventional transparent chip paper as described above are reduced or overcome.

  According to the present invention, the cigarette rod, the filter disposed at the downstream end of the cigarette rod, the tip paper wound around the downstream end of the cigarette rod and the outer peripheral surface of the filter, and connecting the cigarette rod and the filter The chip paper is at least partially transparent, the transparent portion has a smoothness of 1500 sec or less and a transparency of 30% or more, and the chip paper is made of paper. A cigarette with a filter is provided.

  According to the present invention, the problems of the conventional transparent chip paper such as the discomfort of the smoker due to the touch like plastic and the difficulty of production are reduced or overcome, and the ink has good ink fixing properties. A cigarette with a filter comprising chip paper that is at least partially transparent can be provided.

  Several embodiments will be described below with reference to the drawings. Throughout the embodiments, the same components are denoted by the same reference numerals, and redundant description is omitted. Each figure is a schematic diagram for facilitating understanding of the embodiment, and its shape, dimensions, ratio, and the like are different from actual ones. In this specification, the terms “upstream” and “downstream” are used as appropriate, and these are based on the direction of mainstream smoke when a cigarette with a filter is smoked.

(First embodiment)
FIG. 1 is an enlarged schematic cross-sectional view showing a part of a cigarette 1 with a filter according to the first embodiment. The cigarette 1 with a filter includes a cigarette rod 11, a filter 12, and chip paper 13.

  The cigarette rod 11 includes a cigarette notch 111 and a cigarette paper 112 wound around the cigarette notch 111 in the same manner as a normal cigarette. The cigarette paper 112 is a paper having air permeability.

  The filter 12 is disposed at the downstream end of the cigarette rod 11. The filter 12 has the same or substantially the same diameter as the cigarette rod 11. The filter 12 includes a filter member 121 and an outer filter winding sheet 122 that winds around the filter member 121. The filter 12 has a so-called plain filter structure composed of a single filter member.

  The filter member 121 is made of, for example, cellulose acetate fiber.

  The entire outer filter take-up sheet 122 is transparent. Examples of the material of the outer filter winding sheet 122 include glassine paper, parchment paper, paraffin paper, cellophane, polypropylene film, polyvinyl chloride film, and cellulose acetate film.

  The chip paper 13 is wound around the downstream end of the cigarette rod 11 and the outer peripheral surface of the filter 12, and connects the cigarette rod 11 and the filter 12. The chip paper 13 is bonded to the cigarette rod 11 and the filter 12 by a normal adhesive used for manufacturing a cigarette with a general filter. The type of adhesive for adhering the chip paper 13 to the cigarette rod 11 and the filter 12 is not particularly limited, but a vinyl acetate adhesive, starch or a modified starch adhesive may be used, and drying is performed. In this case, an adhesive that becomes substantially transparent may be used. Moreover, the area | region which apply | coats an adhesive agent may cover the whole area | region of an adhesive surface, as long as the objective which connects the chip paper 13 cigarette rod 11 and the filter 12 can be achieved, and the area | region where the adhesive agent is not apply | coated partially There may be. The chip paper 13 is entirely transparent and has a transparency of 30% or more and 100% or less, preferably 60% or more and 90% or less, and more preferably 80% or more and 90% or less. In the present invention, the transparency is measured in accordance with ISO 2470 and ISO 2471 using a whiteness / opacity measuring device (manufacturer: Murakami Color Research Laboratory, model number: WMS-1), respectively. The value calculated by transparency (%) = 100−opacity (%). Whiteness is an intrinsic reflectance coefficient (R∞) measured using a specified reflectometer and a light source under spectral conditions having an effective wavelength of 457 nm and a full width at half maximum of 44 nm. It is a value calculated by the reflectance coefficient (R0) / the intrinsic luminous reflectance coefficient (R∞) × 100 (%).

  Further, at the time of manufacture, when the chip paper 13 is bonded to the cigarette rod 11 and the filter with an adhesive, the chip does not deteriorate the adhesiveness with the adhesive and does not feel or reduce the feel like plastic. The paper 13 has a smoothness of 1500 sec or less, preferably 1200 sec or less.

  Further, when the chip paper 13 is wound around the downstream end portion of the cigarette rod 11 and the outer peripheral surface of the filter 12, the chip paper 13 is difficult to cut and can be wound according to the shape of the cigarette with filter. 13 has a basis weight of 20-100 gsm, preferably 25-50 gsm. For the same reason, the chip paper 13 has a thickness of 15 to 80 μm, preferably 18 to 40 μm.

  Further, the chip paper 13 has a lower shrinkage rate than the conventional transparent chip paper using cellophane so that the dimensions thereof are difficult to change even in a situation where the humidity environment changes during manufacturing or smoking. ing. For example, when the chip paper 13 is stored for 24 hours in an environment of 23 ° C. and a relative humidity of 100% and then stored for 24 hours in an environment of 23 ° C. and a relative humidity of 100%, the chip paper 13 is 1% or less. It is preferable to show a shrinkage rate in the MD (Machine Direction) direction (flow direction) and a CD (Cross Direction) direction (width direction) shrinkage of 1.5% or less. After that, when stored for 24 hours in an environment of 23 ° C. and a relative humidity of 44%, the MD (Machine Direction) direction shrinkage rate (flow direction) is 2% or less, and the CD (Cross Direction) direction (width) is 2% or less. (Direction) It is preferable to show shrinkage.

  The chip paper 13 satisfies general physical properties required for the chip paper. Specifically, it has a tensile strength of 26.0 N / 15 mm or more and a stiffness of 1.0 g / 25 mm or more. Furthermore, the chip paper 13 preferably has an elongation of 1.0% or more and 2.0% or less. The stiffness was measured by cutting a 25 mm wide test piece from the chip paper 13 and fixing both ends of the test piece on a measuring machine (Toyo Seiki Seisakusho, Loop Stiffness Tester). The tensile strength and elongation were measured according to JIS P 8113-1998, using a strograph EL manufactured by Toyo Seiki Seisakusho.

  The chip paper 13 is made of paper satisfying the above-mentioned physical properties, and examples of such paper include glassine paper, parchment paper, or paraffin paper. Specifically, 40.0 special thickness-preserved white glassine (Nippon Paper Papillia Co., Ltd.) Company: glassine paper) 25.8 thin white glassine (Nippon Paper Papillia Co., Ltd .: glassine paper) Grafan 35gsm (Oji Special Paper Co., Ltd .; glassine paper) JT highly transparent glassine 40 (Nippon Paper Papillia Co., Ltd .; glassine paper) Can be mentioned.

  When smoking such a cigarette 1 with a filter, the mainstream smoke from the cigarette rod 11 passes through the filter 12 and is discharged from the downstream end of the filter 12. At this time, the substance (for example, tar etc.) contained in the mainstream smoke accumulates in the filter 12, so that the color of the filter 12 gradually changes according to the number of times the smoker sucks the cigarette. Since the cigarette 1 with a filter according to the present embodiment includes the chip paper 13 and the filter winding sheet 122 that are transparent as a whole, the color of the filter 12 gradually passes through the chip paper 13 and the filter winding sheet 122 from the outside. You can see how it changes.

  Further, since paper is used as the transparent chip paper, it is possible to reduce or overcome the feeling of the chip paper like plastic, which has been a problem in the conventional transparent chip paper using cellophane.

FIG. 6 is an enlarged schematic cross-sectional view showing a part of the cigarette 5 with a filter according to the fifth embodiment. In the cigarette 5 with a filter according to the fifth embodiment, the destructible fragrance capsule 55 is disposed in the hollow portion 44 except that a destructible fragrance capsule 55 that can be broken by receiving an external force to release the internal fragrance is disposed. 4 has the same configuration as the cigarette 4 with a filter according to the fourth embodiment.

  The fragrance capsule 55 includes, for example, a content fragrance 551 and a film 552 that covers the content fragrance 551. As a material of the film 552, for example, starch, dextrin, polysaccharide, agar, gellan gum, gelatin, various natural gelling agents, glycerin, and the like can be used. Further, the film 552 can further include a fragrance, a colorant, and the like in addition to the above materials. The fragrance capsule 55 is preferably colored with a colorant or the like so that it can be easily seen by a smoker when crushing. As the content fragrance 551, for example, menthol, plant essential oil and the like can be used. As a solvent for the content fragrance 551, a solvent suitable for the fragrance can be used, and medium chain fatty acid triglyceride (MCT) (specifically, glyceryl tricapryl / caprate), propylene glycol, water, ethanol, etc. can be used. it can. The fragrance | flavor 551 may contain other additives, such as another solvent, a pigment | dye, an emulsifier, and a thickener.

  Although the manufacturing method of the fragrance | flavor capsule 55 is not specifically limited, For example, if the dripping method is used, the fragrance | capacitance capsule 55 which has the seamless membrane | film | coat 552 without a joint can be manufactured. In this dripping method, by using a double nozzle, the content fragrance 551 from the inner nozzle is discharged simultaneously with the liquid film material from the outer nozzle, so that the film 552 wraps the content fragrance 551 without having a seam. it can.

  In addition to the advantages described with respect to the fourth embodiment, according to the cigarette 5 with a filter according to the fifth embodiment, the smoker crushes the fragrance capsule 55 so that the film 552 is broken, and the content fragrance 551 from within the capsule 55.

In the cigarette 5 with a filter according to the present embodiment, the chip paper 13 and the outer filter take-up sheet 42c corresponding to the hollow portion 44 are transparent, so that the fragrance capsule 55 in the hollow portion 44 can be visually recognized from the outside. it can. Therefore, it becomes easy to destroy the fragrance capsule 55, and it can be visually confirmed that the fragrance capsule 55 is broken. Further, it can be visually confirmed that the fragrance 551 of the fragrance capsule 55 has developed in the hollow portion 44. Thereby, the smoker can enjoy the scent after confirming that the content fragrance 551 of the fragrance capsule 55 is sufficiently developed in the hollow portion 44. When a liquid fragrance is used as the content fragrance, it is preferable that both or one of the chip paper 13 and the outer filter take-up sheet 42c does not transmit the liquid. In order to prevent the tip paper 13 and / or the outer filter winding sheet 42c from penetrating the liquid, nitrocellulose on the front surface, back surface, or both surfaces of the chip paper 13 and the outer filter winding sheet 42c, A liquid impervious layer may be formed by applying a resin such as ethyl cellulose, PVA, or PVAc, or a liquid impervious layer using a substance having a low affinity with the content fragrance 551 may be formed. . For example, when MCT is a main component as a solvent for the content fragrance 551, the material of the liquid impervious layer is relatively hydrophilic, such as starch, modified starch, pectin, sodium alginate, gellan gum, tamarind gum, and carrageenan. A polysaccharide having the following characteristics can be used. By making the outer filter take-up sheet 42c impervious, it is possible to prevent the perfume from permeating into the chip paper 13, and the smoker can clearly confirm that the perfume is released in the filter. Is desirable.

(Sixth embodiment)
FIG. 7 is an enlarged schematic cross-sectional view showing a part of the cigarette 6 with a filter according to the sixth embodiment. The cigarette with filter 6 according to the sixth embodiment has the same configuration as the cigarette 4 with filter according to the fourth embodiment except that the flavor particles 66 are arranged in the hollow portion 44.

  As the flavor particles 66, for example, plant dried granules that are pulverized after drying, alone or in combination, leaves, stems, fruits, or flowers of plants that release flavor components, pulverized after drying these plants, sugar powder, starch powder, Granules containing dried plant powder prepared by mixing with a substrate such as cellulose powder or cellulose acetate powder and then extruding by mixing with binder, or flavor substances extracted from these plants with activated carbon and pore structure A structure cellulose granule, a cellulose acetate granule having a pore structure, a granule having pores derived from clay such as zeolite, silica gel, montmorillonite, and hydroxyapatite can be used. From the viewpoint that a smoker can visually recognize these flavor particles 66 and recall an image such as a refreshing feeling, it is preferable to use a dried product of mint leaves as the flavor particles 66. The shape of the flavor particles 66 is not particularly limited. For example, it is easy to fill the hollow portion 44 such that the particles are about 12 mesh passing and 32 mesh non-passing (equivalent to 0.5 to 1.4 mm), and From the viewpoint of visibility from the transparent portion of the chip paper 13, it is preferable. The mint leaves used as the flavor particles 66 may be simply dried and pulverized, or may be those obtained by adding a flavor such as l-menthol after dry pulverization.

  In addition to the advantages described with respect to the fourth embodiment, the cigarette 6 with a filter according to the sixth embodiment passes through the hollow portion 44 when smoking because the flavor particles 66 are disposed in the hollow portion 44 of the filter 42. A flavor is added to the mainstream smoke, so that a flavor different from that of a normal cigarette can be tasted, and the content can be visually recognized by the smoker, thereby realizing a further change in flavor. Further, by setting the filling rate of the flavor particles 66 in the hollow portion 44 to 30% or more and 70% or less, the smoker can move the flavor particles 66 in the hollow portion 44 due to the flow of mainstream smoke during smoking. You can also feel the vibrations and sounds caused by hitting each other. At that time, a plurality of holes (ventilation holes) extending through the chip paper 13 and the outer and inner filter winding sheets 42c, 422a, 422b to reach the filter members 421a, 421b are positions corresponding to the hollow portions 44. Alternatively, by providing at a position corresponding to the first filter segment 42a located upstream of the hollow portion 44, movement and collision of the flavor particles 66 in the hollow portion 44 are promoted by the air flow introduced from the outside. Therefore, it is more preferable. The filling rate of the flavor particles 66 can be calculated by dividing the volume occupied by the flavor particles 66 immediately after filling the hollow portions 44 with the flavor particles 66 by natural fall by the volume of the hollow portions 66. In calculating the filling rate of the flavor particles 66, the flavor particles 66 are not densely packed by, for example, applying vibration after filling the flavor particles 66 by natural fall.

(Seventh embodiment)
FIG. 8 is a perspective view of a cigarette 7 with a filter according to the seventh embodiment. 9 is an enlarged schematic cross-sectional view showing a cross section taken along line IX-IX in FIG. The cigarette 7 with a filter according to the seventh embodiment has the same configuration as the cigarette 1 with a filter according to the first embodiment, except that the outer filter winding sheet 722 has a decorative portion 77.

  As shown in FIG. 9, the decorative portion 77 has a star shape. Such a decoration part 77 can be formed by printing ink etc. on the surface and / or back surface of the outer filter winding sheet 722 by gravure printing or inkjet printing, for example. FIG. 9 shows an example of the decorative portion 77 having a star shape, but the shape of the decorative portion 77 is not limited to this, and may be, for example, a character, a geometric shape, a logo mark, or the like. Good.

  In addition to the advantages described in the first embodiment, the filter cigarette 7 according to the seventh embodiment is such that the tip paper 13 is transparent, so that the decorative portion 77 of the outer filter take-up sheet 722 passes through the chip paper 13. A cigarette with a filter that can be seen through from the outside and has excellent design properties can be provided.

(Eighth embodiment)
FIG. 10 is a schematic perspective view of a cigarette 8 with a filter according to the eighth embodiment. 11 is a schematic cross-sectional view showing an enlarged cross section taken along line XI-XI in FIG. The cigarette 8 with a filter according to the eighth embodiment has the same configuration as the cigarette 1 with a filter according to the first embodiment, except that the chip paper 83 has a decorative portion 88.

  As shown in FIG. 10, the decorative portion 88 has a star shape. Such a decoration part 88 can be formed by printing ink etc. on the surface and / or back surface of the chip paper 83 by gravure printing or inkjet printing, for example. FIG. 10 shows an example of the decorative portion 88 having a star shape. However, the shape of the decorative portion 88 is not limited to this, and examples thereof include characters, geometric shapes, logo marks, and the like. Good.

  Since the chip paper 83 is transparent, even if the chip paper 83 has the decorative portion 88 on the back surface, the decorative portion 88 can be visually recognized from the outside.

  In addition, the cigarette with a filter according to each of the embodiments described above may have other configurations, for example, a plurality of holes (ventilation) that penetrate the chip paper and the outer and inner filter winding sheets to reach the filter. Hole). The plurality of holes may have, for example, an elliptical shape in which each hole has a major axis of 0.1 to 2.0 mm, and a plurality of holes are formed at intervals of 0.2 to 2.0 mm. Also good. Such ventilation holes serve to supply air into the filter from the outside. It is possible to prevent the smoker's lips from closing the hole for ventilation by making a hole 12 mm or more away from the suction end of the filter.

(Test example)
Tests (1) to (4) described below were performed using the test samples 1 and 2 and the test papers 1 to 3 having the physical property values shown in Table 1. In Table 1, “printed” means that the surface of the chip paper was coated with ink by printing.

(1) Cigarette manufacturing test When using normal chip paper base paper, test samples 1 and 2 and a comparative test using a cigarette manufacturing machine capable of manufacturing 12,000 cigarettes with a filter per minute Winding of chip paper such as the operable speed of cigarette manufacturing machine (number of cigarettes that can be produced per minute) and the rate of defective cigarettes with filter when winding sample paper of samples 1 to 3 on a cigarette with a filter Tested for sex. The results are shown in Table 2. Note that the defect occurrence rate means that when chip paper is wound around a cigarette with a filter, the end of the end of the chip paper is weakly bonded and the end of the chip paper is peeled off from the cigarette with a filter. Express the probability of In addition, EVA emulsion paste, which is a normal adhesive used in the manufacture of a cigarette with a general filter, was used for bonding the chip paper to the filter and cigarette rod.

  The chip papers of comparative test samples 1 and 2 were difficult to wind a cigarette rod and a filter with a cigarette manufacturing machine. Moreover, the cigarette rod and the filter were able to be wound by low speed conditions about the comparative test sample 1 using the cellophane which has not printed on the surface by using a special glue and a special apparatus. However, since the chip paper of Comparative Test Sample 1 has no coating agent or printing on the surface, it has a high moisture absorption / release property of cellophane, and receives the fluctuation of the moisture in the environment after cigarette winding. There was an event that the arm was stretched or deformed.

  On the other hand, the comparative test sample 3 uses a chip paper base paper used for ordinary chip paper, and has good winding properties. Moreover, in the test sample 1 and the test sample 2, similarly to the case of using a normal chip paper base paper (comparative test sample 3), the operable speed is 12,000 pieces / min, and the defect occurrence rate is 0%. It was found to have good winding properties.

  As described above, it can be seen that the chip paper using the glassine paper solves the problem of the winding property that the transparent chip paper using the conventional cellophane has.

(2) Ink Fixability Test An ink fixability test was performed on chip paper (25 × 250 mm) of Test Sample 2, Comparative Test Sample 2, and Comparative Test Sample 3. Ink is applied to the surface of the chip paper of Test Sample 2 and Comparative Test Sample 3 by printing. Moreover, the surface of the chip paper of the comparative test sample 2 is coated with ink by printing and further coated with a varnish on the upper surface. A Gakushin type friction measuring machine (manufacturer: tester industry, trade name: RUBING TESTER, model number: AB-301) was used for the ink fixing test.

  FIG. 12 is a diagram for explaining the ink fixability test. The friction measuring machine 9 includes a friction piece 91 and a stainless steel board 92. The friction element 91 includes a semi-columnar friction element body 91a, an arm 91b that supports the friction element body 91a, and the like. A white test paper 93 for observing ink drop is attached to the bottom surface of the friction element 91. A chip paper 94 is fixed on the upper surface of the semi-cylindrical stainless steel board 92.

  In the ink fixing property test, the friction tester 91 is placed on the chip paper 94 so that the white test paper 93 comes into contact with the printed chip paper 94 of the stainless steel board 92, and the printed chip paper 94 is rubbed by 40 reciprocating frictions. Thereafter, the white test paper 93 was observed to evaluate the degree of color fading. When the friction element 91 is placed on the chip paper 94, the load of the friction element main body 91a and the arm 91b is applied to the white test paper 93 and the chip paper 94. The ink fixability test was carried out by dry test and wet test, both of which were performed at room temperature. In the wet test, 20 μl of water was dropped on the surface of the chip paper 94 before starting the friction.

  As a result of the ink fixing test, the noticeable ink drop was not observed in the dry test of the chip paper of Comparative Test Sample 2, but the ink drop was observed in the wet test. On the other hand, with regard to the chip papers of the test sample 2 and the comparative test sample 3, no conspicuous ink drop was observed in the dry test and the wet test. Therefore, chip paper using glassine paper has better ink fixability than chip paper using cellophane, and has good ink fixability equivalent to the case of using general-purpose chip paper base paper. It was confirmed that

(3) Shrinkage test About the chip paper of the test sample 1, the test sample 2, the comparative test sample 1, and the comparative test sample 2, the shrinkage test was done. In the shrinkage test, the chip paper to be tested was measured for 24 hours in an environment of 23 ° C. and a relative humidity of 60%, and this was used as the initial state. Then, it stored for 24 hours in the environment of 23 degreeC and relative humidity 100%, and measured the dimension of the flow direction and the width direction. Furthermore, it was kept for 1 hour in an environment of 23 ° C. and a relative humidity of 44% and stored for 24 hours, and the dimensional change in the flow direction and the width direction was measured. The shrinkage rate was evaluated by measuring the dimensional change in the flow direction and width direction of the chip paper based on the initial state at that time. The results are shown in Table 3. In Table 3, the shrinkage rate indicates a positive value when the chip paper is contracted from the initial size as a result of the measurement, and a negative value when the chip paper is expanded.

  As is clear from Table 3, the chip papers of Test Sample 1 and Test Sample 2 were stored under dry conditions at 23 ° C. and 44% relative humidity even when stored under wet conditions at 23 ° C. and 100% relative humidity. Also when compared, the shrinkage in the flow direction and the shrinkage in the width direction were lower than the chip papers of the comparative test sample 1 and the comparative test sample 2. From this, it was confirmed that the chip paper using glassine paper is less affected by humidity than the chip paper using cellophane.

Experimental example 4: Sensory test In the sensory test, a cigarette with a filter using the tip paper of test sample 2 and a cigarette with a filter using the chip paper of comparative test sample 2 were actually smoked by 10 panels. It was carried out by evaluating the presence or absence of a chip paper-like feel when the chip paper touches the lips or tongue of the panel. As a result, the number of people who evaluated that the chip paper feels like a plastic was 9 out of 10 in the cigarette with a filter using the comparative test sample 2 as the chip paper, whereas the test sample 2 was used. In the cigarette with filter, it was 2 out of 10 people. In addition, the number of people who evaluated that there was no feel like plastic of chip paper was 0 out of 10 in the cigarette with a filter using the comparative test sample 2, whereas the cigarette with a filter using the test sample 2 Then 5 out of 10 people.

  As described above, in the cigarette with a filter using glassine paper as the chip paper, the feel like a plastic of the chip paper is reduced as compared with the cigarette with a filter using the conventional transparent chip paper (cellophane). It was confirmed.
