Description

Smoking articles with filters

The present invention relates to a smoking article with a filter.

In order to respond to diversification of smoker's preference, a technique is known in which a taste stimulating component different from the flavor given by tobacco is applied to various parts of a smoking article such as cigarette. For example, Patent Document 1 discloses that a taste stimulating component such as caffeine or coffee extract is added to the outer surface of a chip paper around which a cigarette filter is wound. For example, Patent Document 2 discloses embedding taste stimulating components such as mint, peppermint, coffee, and the like in a filtration region of a cigarette filter.

By the way, since it is difficult to add a large amount of taste stimulating component to the outer surface of the chip paper around which the filter of the smoking article is wrapped, in order to hold a relatively large amount of the taste stimulating component in the filter, the inner region of the filter is also tasted. Stimulation components need to be placed. However, when a taste stimulating component is simply added to the filter medium, the taste stimulating component is mixed with mainstream smoke generated during smoking. As a result, the flavor imparted by the tobacco is affected by the taste stimulating component, and it is difficult to taste the flavor of the tobacco when smoking. Moreover, when arrange | positioning a taste stimulating component only to the internal area | region of a filter, it is difficult for a user to taste a taste stimulating component before smoking. Therefore, in the prior art, when a relatively large amount of taste stimulating component is disposed in the filter, the flavor and taste stimulating component imparted by the cigarette can not be tasted separately, and the smoker's preference is fully satisfied. It's hard to say.

This invention is made | formed in view of said subject, Comprising: The objective is to provide the smoking article with a filter which can taste separately the savory taste and taste stimulating component which a tobacco engraving gives. .

In order to solve the above-mentioned problems, the present invention provides a smoke flow path in which a taste stimulus imparting material containing a taste stimulus component is disposed in a filter of a smoking article with a filter, and mainstream smoke passes through a part of the cross section of the filter. The remainder of the cross section is occupied by the taste stimulating material so that is formed.

In more detail, the smoking article with a filter according to the present invention includes a tobacco rod including a tobacco cut, a filter connected to one end of the tobacco rod, and a taste stimulus including a taste stimulus component disposed in the filter. And the taste stimulating material occupies the remainder of the cross section so that a smoke flow path for allowing mainstream smoke to pass is formed in a part of the cross section of the filter.

According to the above configuration, when the mainstream smoke that has flowed into the filter from the tobacco rod side flows through the smoke passage during smoking, it is possible to prevent the taste stimulating component from being mixed with the mainstream smoke. Thereby, the smoker can taste the taste of tobacco without being affected by the taste stimulating component. Therefore, according to the present invention, it is possible to taste the taste of tobacco and the flavor of the taste stimulating component separately, so that the smoker's preference can be fully satisfied. In the present invention, the smoke flow path may be hollow. According to this, there is an advantage that when the mainstream smoke that has flowed into the filter from the tobacco rod side during smoking flows through the smoke passage, the taste stimulating component can be more significantly suppressed from being mixed with the mainstream smoke.

Further, the taste stimulus imparting material may have a non-breathable isolation layer that isolates the taste stimulus component from the smoke flow path. According to this, at the time of smoking of a smoking article, the effect which suppresses that the tobacco flavor is influenced by the taste stimulating component becomes more remarkable.

In the present invention, the taste stimulating component may be arranged on the outer peripheral side in the cross section of the filter, and the outside of the taste stimulating component may be covered with a liquid-permeable sheet. According to this, a taste stimulating component can be ingested indirectly through the saliva which permeate | transmits a liquid-permeable sheet, and a smoker can taste the flavor of a taste stimulating component suitably. Moreover, it can suppress that a taste stimulating component falls out of a smoking article during the retention period of a smoking article.

In the present invention, the taste stimulating component may be impregnated with saliva that permeates through the liquid-permeable sheet to express a flavor that stimulates the taste. Thereby, a smoker can taste the flavor of a taste stimulating component suitably.

In the present invention, at least a part of the region covering the taste stimulating component of the liquid-permeable sheet may be exposed without being covered by the chip paper around which the filter is wound. By comprising in this way, a smoker can taste a taste stimulating component easily.

In the present invention, the taste stimulus imparting material may be disposed on the mouth end side of the filter. According to this, at the time of smoking, the portion closer to the tobacco rod than the taste stimulating component is more likely to be scolded by the smoker, and the flavor imparted by the tobacco without being affected by the taste stimulating component alone You can taste it.

In the present invention, the rear end of the chip paper around which the filter is wound may be disposed at a position within 8 mm from the suction end of the filter. According to this configuration, when smoking, it is possible to remarkably increase the possibility that a portion near the tobacco rod will be scolded by the smoker rather than the taste stimulating component, and the cigarette is not affected by the taste stimulating component during smoking. You can taste the savory flavor alone.

Further, in the present invention, the liquid-permeable sheet is covered with chip paper around which the filter is wound, and the chip paper includes at least a part of a region of the liquid-permeable sheet that covers the taste stimulating component. A removal means for partially removing the chip paper may be provided so that is exposed. According to this, since the chip paper is partially removed using the removing means, at least a part of the region covering the taste stimulating component of the liquid-permeable sheet is exposed. Through this, you can taste the flavor of the taste stimulating component.

Further, in the present invention, the taste stimulating component is disposed on the outer peripheral side in the cross section of the filter, and the outside of the taste stimulating component is directly covered by the chip paper around which the filter is wound, The chip paper may be provided with a removing means for partially removing the chip paper so that at least a part of the taste stimulating component is exposed. According to this, at least a part of the taste stimulating component is exposed by partially removing the chip paper using the removing means, so that the smoker can directly take the taste stimulating component. , You can taste the flavor of taste stimulating ingredients.

Further, in the present invention, the taste stimulus imparting material has a tubular partition member for holding the taste stimulus component and partitioning the taste stimulus component from the smoke flow path, and has an inner periphery of the partition member. The smoke flow path may be formed on the side, and the taste stimulating component may be held on the outer peripheral side of the partition member.

In the present invention, the taste stimulus imparting material may be a cylindrical molded body in which the taste stimulus component is molded into a hollow cylinder, and the smoke flow path may be formed on the inner peripheral side thereof.

Further, in the present invention, the taste stimulus imparting material is a tablet shaped product obtained by shaping the taste stimulating component into a tablet shape, and the smoke flow path penetrates the tablet shaped product along the longitudinal direction of the filter. May be.

In the present invention, the tablet molded body may be exposed to the outside at the mouth end of the filter.

In the present invention, the taste stimulating component may include at least one component selected from coffee, peppermint, pepper, tea leaf, and tobacco leaf-derived components. In the present invention, the taste stimulus imparting material may contain the taste stimulus component in the form of a dried product, a granulated product, or a molded product.

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>
FIG. 1 is an external view of a cigarette 1 according to the first embodiment. FIG. 2 is a longitudinal sectional view of the cigarette 1 according to the first embodiment. The cigarette 1 is a smoking article with a filter including a tobacco rod 2 and a filter 4 connected to one end of the tobacco rod 2 via a tip paper 3.

The tobacco rod 2 is formed by winding the tobacco stamp 21 with a wrapping paper 22 into a cylindrical shape (bar shape), and is also referred to as a “single roll”. The filter 4 is a member for filtering smoke components contained in the mainstream smoke when the mainstream smoke generated when the cigarette 1 is smoked is passed, and is a circle having substantially the same diameter as the tobacco rod 2. It is shaped like a column.

The filter 4 is wound around the chip paper 3 and connected to the rear end side of the tobacco rod 2 via the chip paper 3. The chip paper 3 connects (connects) the end portion of the tobacco rod 2 and the filter 4 by integrally winding the tip paper 3. Hereinafter, in the longitudinal direction (axial direction) of the tobacco rod 2, the end connected to the filter 4 is referred to as “rear end”, and the opposite end is referred to as “front end” (front end). In the longitudinal direction (axial direction) of the filter 4, the end connected to the tobacco rod 2 is referred to as “front end”, and the end opposite to the front end is referred to as “mouth end”. The chip paper 3 partially covers the outer periphery of the filter 4 except for the suction end side in the longitudinal direction of the filter 4. In addition, a cross section in a direction orthogonal to the longitudinal direction (axial direction) of the cigarette 1 (the tobacco rod 2 and the filter 4) is defined as a “cross section”.

Inside the filter 4, a filter segment 7 and a taste stimulus imparting material 8 are connected in series from the front end side, and the taste stimulus imparting material 8 is disposed on the mouth end side of the filter 4. The filter segment 7 is a filter medium in which a filter material, which is a fiber bundle of cellulose acetate formed into a columnar shape, is wound with a wrapping paper. However, in this embodiment, the filter segment 7 is not limited to a cellulose acetate filter, and various filter materials can be employed.

Next, the details of the taste stimulus imparting material 8 will be described. FIG. 3 is a perspective view of the taste stimulus imparting material 8. The taste stimulus imparting material 8 is formed including a partition member 9 and a taste stimulus component 10 held by the partition member 9. FIG. 4 is a perspective view of the partition member 9. The partition member 9 is a cylindrical body having a substantially drum shape. As shown in FIG. 4, the partition member 9 has a holding concave portion indicated by reference numeral 9A and

end portions

9B and 9C sandwiching both ends of the holding concave portion 9A, and has a hollow smoke flow on the inner peripheral side thereof. A path 9D is formed. As illustrated, the outer diameter of the holding recess 9A is set smaller than the outer diameters of the

end portions

9B and 9C, so that the outer peripheral surface of the holding recess 9A is smaller than the outer peripheral surfaces of the

end portions

9B and 9C. It has a concave shape. As shown in FIG. 3, the taste stimulating component 10 is held in the holding recess 9 A formed on the outer peripheral side of the partition member 9. The partition member 9 holds the taste stimulating component 10 in the holding recess 9A formed on the outer peripheral surface side, and partitions the smoke flow path 9D and the taste stimulating component 10 formed on the inner peripheral surface side (FIG. 2). See).

Here, the taste stimulating component 10 is a component that imparts a stimulus to the taste when taken by a smoker. As will be described in detail later, the smoker takes the taste stimulating component 10 at an arbitrary timing such as before smoking, during smoking, and after smoking, thereby giving a flavor different from the flavor imparted by the tobacco 21 during smoking. You can taste it alone. Here, the taste stimulating component 10 is not particularly limited as long as it contains a component that stimulates the taste by being taken by a smoker. For example, components derived from coffee, peppermint, chili pepper, tea leaf, and tobacco leaf are used. It may contain at least one component selected from In the present embodiment, coffee powder is employed as the taste stimulating component 10, and the coffee powder is held in the holding recess 9 A of the partition member 9. The form of the taste stimulating component 10 is not particularly limited, and may be a dried product, a granulated product, a molded product or the like of each component exemplified by coffee, peppermint, chili pepper, tea leaf, tobacco leaf and the like. In addition, you may employ | adopt snus powder as a component derived from a tobacco leaf. The snus powder is tobacco powder granules obtained by cutting or pulverizing tobacco leaf materials.

The code | symbol 11 shown in FIG. 5 is a liquid-permeable sheet which can permeate | transmit a liquid. As shown in FIG. 5, the outer peripheral surface of the taste stimulus imparting material 8 is covered with a liquid-permeable sheet 11. Thereby, the outer peripheral side of the taste stimulating component 10 held in the holding recess 9 A of the partition member 9 is covered with the liquid-permeable sheet 11. The liquid-permeable sheet 11 only needs to have liquid permeability, and may be, for example, a cigarette paper (for example, manufactured by Mody) or a non-woven fabric (for example, viscose) BFF: Oral tobacco packaging fabric). The taste stimulating material 8 configured in this way is connected to the subsequent stage of the filter segment 7, and the rod-shaped filter 4 is manufactured by being wound up integrally by the chip paper 3. When the cigarette paper is used for the liquid-permeable sheet 11, the air permeability of the paper web is preferably 2000 or more and more preferably 10,000 or more. By adjusting the air permeability of the liquid-permeable sheet 11 in this way, it is possible to easily transmit liquid such as smoker's saliva. The air permeability referred to here is determined in conformity with ISO, and passes 1 cm ² per minute when the pressure difference between the upper surface and the lower surface of the liquid-permeable sheet 11 (winding paper) is 100 mmH ₂ O. It is defined as the air flow rate ([CU] = [ml / cm ² · min]).

Next, the manufacturing process of the cigarette 1 will be described. 6 and 7 are diagrams showing a manufacturing process of the cigarette 1. FIG. For example, a first component 91, a second component 92, and a roll 111 of the liquid-permeable sheet 11 as shown in FIG. 6 are prepared. These are used for producing the taste stimulus imparting material 8. Here, the first component 91 has a holding recess forming portion 911 that becomes the holding recess 9A after the partition member 9 is completed, and an end portion forming portion 912 that becomes the end portion 9B after the partition member 9 is completed. Further, the second component 92 has a holding recess forming portion 921 that becomes the holding recess 9A after the partition member 9 is completed, and an end forming portion 922 that becomes the end portion 9C after the partition member 9 is completed. The first component 91 and the second component 92 are cylindrical members. And the internal diameter of the holding | maintenance recessed part shaping | molding part 911 in the 1st component 91 is set to the dimension substantially equal to the outer diameter of the holding | maintenance recessed part shaping | molding part 921 in the 2nd component 92, and the holding | maintenance recessed part shaping | molding

parts

911 and 921 are fitted. Thus, the partition member 9 is assembled. Furthermore, the outer diameter of the end molding portion 912 in the first component 91 and the outer diameter of the end molding portion 922 in the second component 92 are substantially equal.

In manufacturing the taste stimulus imparting material 8, the liquid-permeable sheet 11 is cut into a predetermined length from the roll 111, and the liquid-permeable sheet 11 is bonded to the outer peripheral surface of the end molding portion 912 of the first component 91. The liquid-permeable sheet 11 is cut so as to be slightly longer than the outer peripheral length of the end molding portion 912, so that when the liquid-permeable sheet 11 is bonded to the outer peripheral surface of the first component 91, the entire outer peripheral surface is passed through. It can be covered with the liquid sheet 11.

Next, a predetermined amount of coffee powder as the taste stimulating component 10 is added to the gap between the outer peripheral surface of the holding recess forming part 911 and the inner peripheral surface of the liquid-permeable sheet 11 in the first component 91. As a result, the taste recess stimulating component 10 is filled into the holding recess forming portion 911 that becomes the holding recess 9A. Thereafter, the holding recess forming portion 921 of the second component 92 is fitted into the holding recess forming portion 911 of the first component 91. At that time, an adhesive is applied to the outer peripheral surface of the end molding portion 922. Thereby, when the second component 92 is assembled to the first component 91, the liquid-permeable sheet 11 is bonded to the end molding portion 922. Through the above steps, the taste stimulating component 8 is obtained in which the taste stimulating component 10 is held in the holding recess 9A, and the outer peripheral side of the taste stimulating component 10 is covered with the liquid-permeable sheet 11.

Next, the filter segment 7 and the tobacco rod 2 are prepared, the tobacco rod 2, the filter segment 7, and the taste stimulus imparting material 8 are arranged in the order of arrangement, and these are integrally wound by the chip paper 3. The cigarette 1 is completed through the above steps.

As shown in FIG. 2, the partition member 9 is disposed in the filter 4 so that its axial direction extends along the longitudinal direction of the filter 4. And the taste stimulus imparting material 8 is the remainder of the cross section so that a hollow smoke flow path 9D for allowing mainstream smoke to pass through a part of the cross section of the filter 4 is formed along the longitudinal direction of the filter 4. Is occupied. Below, the cross section of the part corresponding to the position where the taste stimulus component 10 of the taste stimulus imparting material 8 is arranged in the filter 4 is referred to as “stimulus component arrangement section”. In the stimulation component installation cross section of the filter 4, the smoke flow path 9 D is formed at the center side, and the taste stimulation component 10 is disposed on the outer peripheral side of the smoke flow path 9 D with the partition member 9 interposed therebetween. In other words, the taste stimulating component 10 and the smoke flow path 9D are partitioned by the partition member 9.

The partition member 9 is made of a material that can block the transmission of the taste stimulating component 10, for example. For example, polyamide, silicon, polyvinyl chloride, fluorine resin, or the like may be used as the material of the partition member 9. Here, the wall part separating the taste stimulating component 10 and the smoke channel 9D in the partition member 9 can also be referred to as a non-breathable isolation layer that isolates the taste stimulating component 10 from the smoke channel 9D.

Further, as shown in FIG. 2, the taste stimulus imparting material 8 is disposed on the mouth end side of the filter 4. Further, the taste stimulus imparting material 8 is wound up by the liquid-permeable sheet 11, so that the outer peripheral side of the taste stimulating component 10 is covered by the liquid-permeable sheet 11. Further, as shown in FIG. 2, the chip paper 3 around which the filter 4 is wound does not cover the mouth end side of the filter 4. In the present embodiment, at least a part of the region covering the taste stimulating component 10 related to the taste stimulus imparting material 8 in the liquid-permeable sheet 11 is not covered with the chip paper 3 but exposed to the outside. The rear end position has been adjusted. Specifically, the rear end of the chip paper 3 is disposed at a position 8 mm from the suction end of the filter 4. In the example shown in FIG. 2, the entire area of the liquid-permeable sheet 11 that covers the taste stimulating component 10 is exposed to the outside. The chip paper 3 is provided with ventilation holes 13 for introducing outside air into the filter 4.

When the smoker ingests the taste stimulating component 10, the taste stimulating component 10 can be indirectly ingested through the saliva that permeates the liquid-permeable sheet 11. That is, the smoker holds the liquid-permeable sheet 11 exposed to the outside on the mouth end side of the filter 4 and wets (wet) the liquid-permeable sheet 11 with saliva. Thereby, a smoker's saliva permeate | transmits the liquid-permeable sheet 11, and when the saliva reaches the taste stimulating component 10 arrange | positioned under the liquid-permeable sheet 11, the taste stimulating component 10 impregnates saliva. As a result, a flavor that stimulates the taste of the smoker is expressed, and the smoker indirectly ingests the taste stimulating component 10 via the saliva impregnated with the taste stimulating component 10 to thereby obtain the flavor of the taste stimulating component 10. You can taste it at any time. In addition, in the stimulation component arrangement cross section of the filter 4, the smoke flow path 9D is formed on the center side, and the taste stimulus imparting material 8 is arranged on the outer peripheral side, so that the smoker easily ingests the taste stimulus component 10. There is also an advantage that it can be done.

Moreover, in this embodiment, since the structure which covers the outer peripheral side of the taste stimulating component 10 with the liquid sheet 11 was employ | adopted, for example, the taste stimulating component 10 falls off from the division member 9 during the retention period of the cigarette 1. There is also an advantage that it can be suppressed. However, the taste stimulating component 10 may not necessarily be covered by the liquid-permeable sheet 11, and the taste stimulating component 10 may be exposed to the outside. In this case, the smoker can directly take the taste stimulating component 10 exposed to the outside.

Furthermore, in the present embodiment, the taste stimulating material 8 is disposed so as to occupy the remainder of the cross section so that a hollow smoke channel 9D is formed in a part of the cross section of the filter 4. Therefore, the taste stimulating component 10 is hardly mixed with the mainstream smoke. Thereby, the smoker can taste the flavor of the tobacco 21 without being affected by the taste stimulating component 10. However, the smoke flow path 9D may not have a hollow structure. For example, the filter medium may be disposed on the portion forming the smoke flow path 9D, that is, on the inner peripheral side of the partition member 9, and in this case, a smoke flow path through which mainstream smoke passes is formed inside the filter medium. become. Moreover, according to the filter 4 in this embodiment, since the taste stimulating component 10 is not added to the outer surface of the chip paper 3 and the taste stimulating component 10 is arranged in a part of the stimulating component arrangement cross section, the comparison is made. A large amount of the taste stimulating component 10 can be held in the filter. Therefore, according to the cigarette 1 according to the present embodiment, even when a relatively large amount of the taste stimulating component 10 is arranged in the filter 4, the taste of the tobacco 21 and the flavor of the taste stimulating component 10 can be tasted separately. Therefore, it becomes possible to satisfy the smoker's preference sufficiently.

Further, in the present embodiment, the taste stimulating component 10 and the smoke flow path 9D are partitioned by the partition member 9 of the taste stimulus imparting material 8, so that the taste stimulating component 10 is added to the mainstream smoke flowing through the smoke flow path 9D during smoking. Can be suitably suppressed. In particular, the partition member 9 is formed of a material that blocks the permeation of the taste stimulating component 10, and the partition member 9 functions as a non-breathable separating layer that separates the taste stimulating component 10 and the smoke flow path 9D. In addition, the effect of suppressing the taste of tobacco taste 21 from being influenced by taste stimulating component 10 becomes more prominent.

In the present embodiment, since at least a part of the region covering the taste stimulating component 10 in the liquid-permeable sheet 11 is exposed without being covered with the chip paper 3, the smoker can easily apply the taste stimulating component 10 to the smoker. You can taste it.

Moreover, in this embodiment, since the taste stimulus imparting material 8 is disposed on the mouth end side of the filter 4, the smoker can hold the tip paper 3 without consciousness at the time of smoking. The savory taste imparted by the tobacco 21 can be enjoyed without being affected by 10. Thereby, at the time of smoking, a smoker's preference that he / she wants to taste the savory taste of the tobacco 21 can be satisfied without ingesting the taste stimulating component 10.

In addition, when referring to the position where the smoker picks up the filter when smoking cigarettes, it has been found that there is a tendency to pick up 8 to 11 mm from the end of the mouth. On the other hand, in this embodiment, since the rear end position of the chip paper 3 is arranged at a position 8 mm from the suction end of the filter 4, the smoker unconsciously holds the filter 4 while smoking. The possibility of holding the chip paper 3 increases. In other words, there is an advantage that the possibility that the smoker's lips come into contact with the liquid-permeable sheet 11 can be reduced even if the smoker is not particularly conscious of holding the tip paper 3 when smoking. In addition, in this embodiment, the rear end of the chip paper 3 should just be arrange | positioned in the position within 8 mm from the mouth end of the filter 4, and when a smoker holds the filter 4 at the time of smoking, the liquid-permeable sheet 11 The effect that it is possible to make it difficult to bring the lips into contact with the lip is obtained.

In addition, as a result of smoking by sucking a portion of the filter 4 that is more than 8 mm away from the mouth end without wetting the mouth end side, all the subjects did not recognize the flavor of the coffee, but only the flavor of the tobacco 21 We were able to.

<Embodiment 2>
Next, a cigarette 1A according to the second embodiment will be described. FIG. 8 is a diagram illustrating a schematic structure of a filter 4A according to the second embodiment. FIG. 9 is a cross-sectional view taken along line AA ′ shown in FIG. The filter 4A according to the second embodiment is different from the taste stimulus imparting material 8 according to the first embodiment in the taste stimulus imparting material 8A continuously provided in the subsequent stage of the filter segment 7. The taste stimulus imparting material 8 A includes a cylindrical partition member 14 having a plurality of groove portions 14 A formed on the outer peripheral surface, and a taste stimulus component 10 held in the groove portion 14 A of the partition member 14. A filter medium 14D is disposed on the inner peripheral side of the partition member 14, and a smoke flow path 14B is formed by the filter medium 14D. In this embodiment, the smoke flow path is used as the filter medium, but the present invention is not limited to this. For example, the filter medium may be hollow processed to form the smoke flow path.

As shown in FIG. 9, a plurality of groove portions 14 A are provided on the outer circumferential surface of the partition member 14 at regular intervals in the circumferential direction of the partition member 14. The plurality of groove portions 14 A are formed along the axial direction of the partition member 14. Further, the partition member 14 is disposed in the filter 4A so that the axial direction of the partition member 14 is along the longitudinal direction of the filter 4A, and thereby the smoke flow path by the filter medium 14D along the longitudinal direction of the filter 4A. 14B is formed.

In this embodiment, as an example, sealing plugs 14 C are provided at both ends of the groove 14 A in the partition member 14. The sealing plug 14C is a sealing material that prevents the taste stimulating component 10 from spilling from the groove 14A when the groove stimulating component 10 is held in the groove 14A. Further, the outer peripheral surface of the taste stimulus imparting material 8 A is covered with the liquid-permeable sheet 11.

When manufacturing the cigarette 1 A, for example, the partition member 14 and the liquid-permeable sheet 11 described above are prepared, and the liquid-permeable sheet 11 is bonded to the outer peripheral surface of the partition member 14.
