Description

Filter cigarette and cigarette package containing the same

The present invention relates to a filter cigarette and a cigarette package containing the filter cigarette.

フィルタ Filter cigarettes with a filter provided on the cigarette mouth are widely known. In the filter cigarette, a filter is connected to one end of a cigarette winding part (cigarette rod) in which a cigarette is wound with a wrapping paper via a chip paper. Such a cigarette filter is formed, for example, by wrapping a filter medium such as an acetate fiber bundle with a web.

Usually, filter cigarettes are distributed in a cigarette package (contained) and sold to consumers. As the cigarette package, a hard package, a soft package, and the like are known. When smoking a filter cigarette, the filter cigarette is taken out from the cigarette package, and smoking is possible by igniting the front end side of the cigarette winding part while holding the filter in the mouth.

However, filter cigarettes are not smoked only in bright places, but may be smoked in dark places. When smoking a filter cigarette in a dark place, the conventional filter cigarette has a problem that visibility in the dark place is low and it is difficult to take out the cigarette package. Further, in the conventional filter cigarette, it may be difficult to confirm in the dark where the filter is located on which side. Further, due to this, there is a possibility that the cigarette winding part side may be accidentally held or the filter may be ignited accidentally.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a filter cigarette having excellent visibility even in a dark place and a cigarette package containing the filter cigarette.

In order to solve the above problems, a filter cigarette according to the present invention includes a cigarette winding portion including a cigarette engraver and a wrapping paper for winding up the outer peripheral portion thereof, a filter connected to the cigarette winding portion via chip paper, A phosphorescent unit provided in the filter.

According to the filter cigarette according to the present invention, the light energy stored in the phosphorescent part is emitted as phosphorescence. Therefore, for example, even when the smoker smokes in the dark, the phosphorescent portion emits light, so that the smoker can easily visually recognize the position of the filter of the filter cigarette. That is, the visibility of the cigarette is excellent even in a dark place, and the ease of taking out the cigarette is improved. Moreover, even after taking out a cigarette from a cigarette package in a dark place, for example, a smoker can grasp | ascertain the position of a filter easily thanks to the luminous part emitting light. As a result, it is possible to prevent the smoker from mistaking the cigarette winding part side and hence igniting the filter by mistake.

Here, the phosphorescent portion may be provided on the surface of the chip paper. The phosphorescent part can be easily formed by printing phosphorescent ink containing a phosphorescent pigment on the surface of the chip paper with a printing machine or the like.

Further, the phosphorescent portion may be arranged in a region of the chip paper that is located closer to the tobacco winding portion than the central portion in the longitudinal direction of the filter. According to this, at the time of smoking, the phosphorescent part is hardly concealed by the smoker's finger, and the light emission of the phosphorescent part can be made conspicuous.

The phosphorescent part may be disposed at an end of the cigarette winding part in the longitudinal direction of the filter. As a result, it becomes difficult for the phosphorescent part to be covered by the smoker's finger during smoking, and the smoker can easily be informed of the boundary between the filter and the cigarette winding part even in the dark. That is, even in a dark place, there is an advantage that the smoker can easily grasp the end of cigarette sucking (time to extinguish).

The filter has a hollow cavity portion inside, the phosphorescent portion includes a phosphorescent member disposed in the cavity portion, and a phosphorescent region covering portion that covers the cavity portion of the chip paper is light transmissive. It may be formed of a property material. According to this, the phosphorescent part can be formed by a method other than applying the phosphorescent ink containing the phosphorescent pigment to the chip paper. According to the above configuration, since the phosphorescent region covering portion of the chip paper is formed of the light transmissive material, sunlight or illumination light is arranged in the cavity portion through the light-transmitting phosphorescent region covering portion. The light can be easily guided to the member, and the light storage in the light storage member can be promoted.

The phosphorescent part is a phosphorescent pigment containing part formed by adding a phosphorescent pigment to the filter medium of the filter, and a phosphorescent region covering part that covers the phosphorescent pigment containing part of the chip paper is formed of a light transmissive material. Also good. According to this, since the phosphorescent region covering portion in the chip paper is formed of the light transmissive material, sunlight or illumination light can be guided to the phosphorescent pigment-containing portion through the phosphorescent region covering portion having translucency. It is possible to promote phosphorescence in the phosphorescent pigment-containing part.

The present invention can also be specified as a cigarette package that accommodates any of the filter cigarettes described above. In this case, a light transmission part for storing the light storage part of the filter cigarette may be provided in a part of the cigarette package.

In addition, the means for solving the problems in the present invention can be employed in combination as much as possible.

According to the present invention, it is possible to provide a filter cigarette having excellent visibility even in a dark place and a cigarette package containing the filter cigarette.

Here, an embodiment of a filter cigarette according to the present invention and a cigarette package containing the filter cigarette will be described with reference to the drawings. The dimensions, materials, shapes, relative arrangements, and the like of the constituent elements described in the present embodiment are not intended to limit the technical scope of the invention only to those unless otherwise specified.

<Embodiment 1>
<Configuration of filter cigarette>
FIG. 1 is a perspective view of a filter cigarette (hereinafter simply referred to as “cigarette”) 1 according to the first embodiment. FIG. 2 is a diagram illustrating an internal structure of the cigarette 1 according to the first embodiment. FIG. 2 schematically shows a cross section including the longitudinal axis of the cigarette 1 (hereinafter referred to as “longitudinal cross section”).

The cigarette 1 includes a cigarette winding part 2 and a filter 4 connected to one end of the cigarette winding part 2 via a chip paper 3. The cigarette winding part 2 is obtained by winding a cigarette 21 with a wrapping paper 22 and has a cylindrical rod shape. The filter 4 is a member for filtering the smoke component contained in the mainstream smoke generated when the cigarette 1 is smoked or for adding a fragrance component. The filter 4 is formed in a cylindrical shape having substantially the same diameter as that of the tobacco winding part 2. The cigarette winding unit 2 and the filter 4 are interconnected by being integrally wound by the chip paper 3. Hereinafter, the end connected to the filter 4 in the cigarette winding part 2 is referred to as a “rear end”, and the end opposite to the end is referred to as a “front end”. In addition, a connection end of the filter 4 with the cigarette winding part 2 is referred to as a “front end” of the filter 4, and an end opposite to the end is referred to as a “suction end” (rear end).

The filter 4 includes a filter medium (filter material) 401 and a winding paper (plug wrap) 402 that winds the filter medium 401 into a cylindrical shape. The filter medium 401 is, for example, a fiber bundle of cellulose acetate, but is not limited thereto.

Next, the chip paper 3 will be described. The chip paper 3 is wound up so as to cover the rear end side of the tobacco winding part 2 and the entire filter 4. A vent hole (not shown) for introducing outside air (air) for diluting mainstream smoke into the filter 4 is formed in an area of the chip paper 3 that covers the periphery of the filter 4. In the chip paper 3, a plurality of vent holes are arranged at regular intervals along the circumferential direction of the filter 4, but the arrangement mode of the vent holes is not particularly limited.

As shown in FIGS. 1 and 2, the cigarette 1 according to this embodiment is provided with a phosphorescent unit 5 containing a phosphorescent pigment on the surface (outer surface) of the chip paper 3. In the present embodiment, the phosphorescent unit 5 is formed by applying phosphorescent ink to the surface of the chip paper 3. Here, “light storage” is sometimes called “nightlight” and refers to the property of a substance that stores light and emits light. The phosphorescent ink refers to an ink (ink) containing a phosphorescent pigment that is a substance having a phosphorescent property. A phosphorescent pigment (phosphorescent component) is a pigment that absorbs light emitted by sunlight, a fluorescent lamp, or the like and emits light by itself. Known phosphorescent pigments can be used such as sulfides such as zinc sulfide, calcium sulfide, germanium sulfide, strontium sulfide, yttrium sulfide, calcium oxide, strontium oxide, barium oxide, alumina, and oxide. Examples thereof include metal oxides such as cerium, aluminates such as calcium aluminate, strontium aluminate, and barium aluminate. The phosphorescent pigment may be activated with at least one element selected from the group consisting of europium, terbium, yttrium, zirconium, dysprosium and barium. In the present embodiment, the phosphorescent portion 5 is formed by applying phosphorescent ink to the surface of the chip paper 3, but the present invention is not limited to this. For example, the phosphorescent part 5 may be formed by kneading a phosphorescent pigment into pulp fibers forming the chip paper 3.

It should be noted that strontium aluminate is preferably used as the phosphorescent pigment from the viewpoints of light emission luminance, afterglow time, and light resistance (a property in which the property of the pigment is hardly changed by light). By using strontium aluminate as the phosphorescent pigment, it is possible to form the phosphorescent part 5 having a high phosphorescent effect and excellent luminescent properties.

The preferable content of the phosphorescent pigment is 5 to 60% by mass with respect to the total amount of phosphorescent ink. If the content of the phosphorescent pigment with respect to the total amount of phosphorescent ink is increased, high light emission (high luminance) is easily obtained, but the layer thickness of the phosphorescent portion 5 formed by the phosphorescent ink applied to the base of the chip paper 3 is large. When it becomes too much, the arrival of light into the layer (in particular, the bottom of the phosphorescent portion 5) may be insufficient. In that case, there is a possibility that a light emitting effect proportional to the layer thickness cannot be obtained. Moreover, when the layer thickness of the phosphorescent part 5 formed with phosphorescent ink becomes too small, there is a possibility that the light emission luminance and the afterglow time cannot be obtained sufficiently. According to the performance required for the phosphorescent unit 5, the mass% of the phosphorescent pigment with respect to the total amount of phosphorescent ink may be appropriately adjusted. The thickness of the phosphorescent portion 5 formed with phosphorescent ink can be exemplified by, for example, 1 to 300 μm, and is preferably adjusted in the range of 5 to 30 μm.

The chip paper 3 to which the phosphorescent ink is applied can be one commonly used for cigarettes, but the light emitting effect of the phosphorescent pigment is better when the base material of the chip paper 3 is light-colored. It is easy to obtain and it is particularly preferable that the substrate is white. In the Munsell color system (Munsell color system), there is an embodiment in which the brightness of the substrate in the chip paper 3 is set to 6 or more and 10 or less. Moreover, it is preferable to set the brightness of the base material in the chip paper 3 to 7 or more and 10 or less, and it is particularly preferable to set it to 8 or more and 10 or less. In the Munsell color system, the brightness of white is 10, and the brightness of black is 1.

In the present embodiment, the method for applying the phosphorescent ink to the chip paper 3 is not particularly limited, but various printing techniques can be used. For example, a phosphorescent ink containing a phosphorescent pigment may be printed on the surface of the chip paper 3 using a printing technique such as offset printing, gravure printing, screen printing, flexographic printing, or the like. Alternatively, the phosphorescent portion 5 may be formed by printing a mixture of UV (ultraviolet) curable ink and a phosphorescent pigment on the surface of the chip paper 3.

Further, the average particle diameter of the phosphorescent pigment contained in the phosphorescent ink forming the phosphorescent part 5 is not particularly limited, but it is preferable that the average particle diameter is larger from the viewpoint of improving the light emission property and the afterglow property. However, from the viewpoint of more uniformly mixing the phosphorescent pigment in the ink, it is preferable that the average particle diameter of the phosphorescent pigment is smaller. In addition, if the average particle diameter of the phosphorescent pigment is excessively large, there is a risk of causing a printing failure (printing failure) such as uneven printing on the surface of the chip paper 3. For example, gravure printing machines and flexographic printing machines are equipped with blade members that are mechanical parts for removing excess ink by contacting intaglios such as engraving rolls, but the average particle size of phosphorescent pigments is excessive. When it is large, the blade member is easily worn. As a result, it becomes impossible to completely remove excess phosphorescent ink on the intaglio plate, which causes a printing defect. Therefore, it is preferable to adjust the average particle diameter of the phosphorescent pigment within a range where printing defects do not occur while ensuring the light emitting property and the afterglow required for the phosphorescent unit 5. When the phosphorescent ink is printed on the surface of the chip paper 3 as in the present embodiment, an example in which the average particle diameter of the phosphorescent pigment is 0.01 to 30 μm can be exemplified, and 1 to 20 μm is preferable, and 1 to 10 μm is preferable. This is particularly preferable.

In the present embodiment, after the phosphorescent ink is printed on the surface of the chip paper 3, the phosphorescent ink may be protected by preferably laminating a translucent overcoat varnish on the phosphorescent ink. The overcoat varnish having translucency may be a colorless transparent layer or a colored transparent layer as long as it does not hinder the transmission of light emission (phosphorescence) from the phosphorescent portion 5. As the overcoat varnish, for example, an acrylic resin, an epoxy resin, a urethane resin, a polyester resin, an ABS resin, or the like can be used.

<Package structure>
3 and 4 are perspective views of a cigarette package (hereinafter simply referred to as “package”) 10 according to the first embodiment. FIG. 5 is a front view of the package 10 according to the first embodiment. The package 10 is a so-called hinge lid type package, and includes a package main body 20 and a lid 30 that is a lid portion hinged to the package main body 20.

In the package 10, the filter 4 of the cigarette 1 is accommodated in the package 10 so as to be positioned on the upper side of the accommodation space. Specifically, the translucent window portion 60 is arranged so that the filter 4 of the cigarette 1 just faces the translucent window portion 60 when the cigarette 1 is accommodated in the package 10. Thereby, even in the state where the cigarette 1 is accommodated in the package 10, the phosphorescent portion 5 formed on the surface of the chip paper 3 in the filter 4 passes through the translucent window portion 60 and enters the accommodation space (inside the package). Because it is exposed to sunlight or illumination light that has entered, it can be stored in the light storage unit 5. In addition, illustration of the translucent window part 60 is abbreviate | omitted in FIG.

The translucent window portion 60 can adopt various modes as long as the light for storing light in the light storage portion 5 of the cigarette 1 can be transmitted into the package 10, and can be a colored transparent film or semi-transparent instead of the colorless transparent film. The opening may be covered with a film. Moreover, it is not necessary to cover the opening with a translucent film. Further, the light transmitting window 60 may be provided at a portion other than the front wall 31 of the lid 30 as long as the light outside the package 10 can be guided to the phosphorescent portion 5 of the cigarette 1 accommodated in the package 10. For example, the translucent window 60 may be provided on the rear wall 32, the left side wall 33, the right side wall 34, and the like of the lid 30. Further, the light transmitting window portion 60 may be provided at a relatively upper position among the front wall 41, the rear wall 42, the left side wall 43, and the right side wall 44 of the outer box 40. By doing so, the package The light can be easily stored in the light storage unit 5 of the cigarette 1 accommodated in the light source 10. Moreover, the number of the translucent window part 60 provided in the cigarette 1 may not be one place, and may be provided in multiple places.

In the present embodiment, the entire package 10 that houses the cigarette 1 may be formed of a light transmissive material.

The cigarette 1 in the present embodiment emits the light energy stored in the phosphorescent unit 5 as phosphorescence. Therefore, for example, even when a smoker smokes in the dark, the phosphorescent portion 5 emits light, so that the smoker can easily recognize where the filter 4 of the cigarette 1 is located. That is, the visibility of the cigarette 1 is excellent even in a dark place, and the ease of taking out the cigarette 1 is improved. In addition, even after taking out the cigarette 1 from the package 10 in a dark place, the smoker can easily grasp the position of the filter 4 thanks to the luminous part 5 emitting light. As a result, it is possible to prevent the smoker from accidentally holding the cigarette winding part side, and hence preventing the filter 4 from igniting accidentally.
