Description

  The present invention relates to a new sense of cigarette that can realize a smoker's fullness.

  In order to reduce the number of tobacco leaves that are discarded, cigarettes with cigarettes that have a mouth part and a cigarette part with a reduced cigarette length and a hollow part are known. Yes. For example, Japanese Patent Application Laid-Open No. 2010-142212 (Patent Document 1) describes a cigarette in which approximately 30% of tobacco leaves are reduced to provide a hollow portion. Japanese Patent Laid-Open No. 2000-325067 (Patent Document 2) discloses a first cylindrical member (cigarette part) filled with tobacco leaves and a second cylindrical member (filter part) filled with a filter material. ), And a third cylindrical member (hollow part) having an opening inside thereof and an opening communicating with the outside between the first cylindrical member and the second cylindrical member. A filtered paper cigarette is described. Since such a cigarette has a hollow portion formed between the cigarette portion and the filter portion, the cigarette leaf can be sucked. However, if the tobacco leaves are sucked, the taste is lost, but the end point of smoking is not clear, so the smoker cannot fully feel the smoke.

  In JP-A-7-327654 (Patent Document 3), a cigarette leaf portion having a length of about 5 cm is set to 1 to 1.5 cm, so that the amount of cigarette leaves can be taken as a dose (20 to 20 hours). Cigarettes reduced to 30 seconds) are described. In this document, a disk mesh filter is provided between the cigarette part and the filter part in order to extinguish the fire of the tobacco leaf. However, if the tobacco leaves remain without being completely burned, the remaining tobacco leaves may adhere to the butts (or filters) to generate odors in the ashtray and cause dirt and the like. In addition, as in Patent Documents 1 and 2, the smoker cannot obtain a full sensation.

JP 2010-142212 A (Claims, [0005]) JP 2000-325067 A (Claims, [0010] [0013]) JP-A-7-327654 (Claims, [0004] [0009] [0011])

  Accordingly, an object of the present invention is to provide a cigarette that can realize (or produce) a smoker's feeling of sucking.

  Another object of the present invention is to provide a cigarette capable of suppressing the leaves of cigarettes from remaining in the cigarette butts and preventing odors and dirt caused by the cigarettes.

  As a result of intensive studies to achieve the above-mentioned problems, the present inventor ignited the explosive layer at the end of the cigarette portion and combusted and pronounced when smoking was performed and the explosive layer was provided adjacent to (or in contact with) the cigarette portion. Therefore, it is possible to produce a smoker's feeling of sucking, and when a cylindrical ventilation part is provided between the explosive layer and the filter part, the expansion pressure of the gas generated by the combustion and the combustion heat act on the filter part. The present invention has been completed by finding that it can be suppressed.

  That is, the cigarette of the present invention is a cigarette including a cigarette part and a filter part, and includes an explosive layer adjacent to the cigarette part, and a cylindrical ventilation part formed between the explosive layer and the filter part. ing.

  The ventilation portion of the cylindrical ventilation portion may be provided with a breathable member and / or a breathable filling layer capable of holding an explosive layer adjacent to the cigarette portion and allowing ventilation. May form a rectifying channel and / or a turbulent channel. The explosive layer may contain at least a nitro compound (for example, nitrocellulose) as an explosive component, for example, a mixture of tobacco leaf and fibrous nitrocellulose. The form of the explosive layer may be a sheet. The amount of explosive component (for example, a nitro compound such as nitrocellulose) may be about 1 to 15 mg in a cigarette having a diameter of 8 mm.

  In the present invention, since the explosive layer is provided adjacent to (or in contact with) the cigarette portion, the explosive layer is ignited at the end of the cigarette portion and can be pronounced with rapid combustion. Therefore, the smoker's feeling of sucking can be improved. Moreover, since the cylindrical ventilation part is formed adjacent to the explosive layer, even if the explosive layer suddenly generates gas, the expansion pressure of the gas and the heat of combustion can be suppressed from acting directly on the filter part, and smoking It can also be suppressed that a person absorbs combustion gas. Furthermore, since the explosive layer is carbonized and solidified with combustion, the remaining tobacco leaves can be burned and the burned tobacco leaves will not fall off. Therefore, it is possible to prevent odors and dirt caused by tobacco leaves, and the ashtray can be kept clean. Such a cigarette is useful as a new sense of cigarette that can improve the smoker's feeling of sucking.

FIG. 1 is a schematic sectional view showing an example of a cigarette of the present invention. FIG. 2 is a schematic sectional view showing another example of the cigarette of the present invention.

  The cigarette of the present invention includes a cigarette part (or engraved part) having cigarette leaves, a filter part having a mouth part, an explosive layer adjacent to the cigarette part in a breathable form, and the explosive layer and filter. And a cylindrical ventilation part interposed between the two parts.

  The gunpowder layer may be close to or adjacent to the cigarette part (or cigarette leaf) as long as it can be ignited at the end of the cigarette part with smoking, and in contact with the cigarette part from the viewpoint of ignitability. Adjacent (or in contact) is preferred. If necessary, the explosive layer may be adhered to the tobacco portion.

  The explosive layer only needs to contain an ignitable component (explosive component). Examples of the ignitable component include conventional explosive components such as nitro compounds (for example, nitrocellulose, nitroglycerin, nitroguanidine, etc.), sulfur, phosphorus (Red phosphorus). These components can be used alone or in combination of two or more. Among these components, nitro compounds [particularly nitrocellulose (or nitrified cotton)] can be preferably used. When an explosive layer containing such an ignitable component (explosive component) is ignited at the end of the cigarette portion, it suddenly burns and sounds, and the end point of smoking can be made clear. Therefore, the smoker can obtain a sufficient feeling of sucking. Furthermore, the residual tobacco leaf can be burned out (or burned out) as the explosive layer burns. Furthermore, since the explosive layer is carbonized and solidified and covers the combustion part, the burnt tobacco leaves are not detached from the butts.

  The explosive layer is composed of other components (for example, tobacco leaves, oxidizing agents (such as potassium chlorate), combustion regulators (such as inorganic powders such as silica powder and diatomaceous earth), binders or adhesives (glue, resin, etc.) ) Etc.) may be included.

  The explosive layer only needs to be disposed adjacent to the cigarette portion in a breathable form, and the cross-sectional shape of the explosive layer is not particularly limited, and is, for example, a circle, an ellipse, a polygon (for example, a triangle, a rectangle, Hexagonal, octagonal, etc.), irregular shapes, etc. Moreover, the form which can be ventilated is a form in which the diameter (average diameter) of the sheet-shaped explosive layer is made smaller than the inner diameter of the cigarette (cigarette part) and a ventilation part is formed in the peripheral part of the explosive layer, and an air passage is provided inside. It may be in the form of a breathable explosive layer having a form in which vent holes are formed in a sheet-shaped explosive layer, an ignitable component (powder component) and the other components (powdered or chopped tobacco) Or an air-permeable mixture with inorganic particulates such as silica). In the form in which the ventilation portion is formed in the peripheral portion of the explosive layer, the diameter of the explosive layer may be, for example, about 50 to 95%, preferably about 60 to 85% with respect to the inner diameter of the cigarette (cigarette portion). . In a preferred embodiment, a sheet-shaped explosive layer can be used. The sheet-shaped explosive layer may be formed of one or a plurality of (for example, about 2 to 5) sheets. In addition, a commercial item (for example, flash paper etc.) can be used for a sheet-like explosive layer.

  The thickness of the explosive layer is relatively thin from the viewpoint of flammability and safety, and is, for example, 0.1 to 5% (for example, 0.5 to 3%), preferably with respect to the axial length of the cigarette May be about 1 to 3%. If the explosive layer is too thick, excessive combustion and explosion may occur.

  The explosive layer may be formed of a packed layer of the breathable mixture, and the breathable mixture is a packed layer of a mixture of an ignitable component (powder component) and other components (such as tobacco leaves), for example, It may be a packed bed of a mixture of nitrocellulose (for example, fibrous nitrocellulose) and tobacco leaves. The weight ratio of the ignitable component (explosive component such as nitrocellulose) and other components (such as tobacco leaves) is, for example, the former / the latter (weight ratio) = 5/95 to 90/10 (for example, 10/90 to 80/20), preferably 20/80 to 75/25 (for example, 30/70 to 70/30), more preferably about 40/60 to 70/30.

  In the cigarette having a diameter of about 8 mm, the amount of the ignitable component (explosive component) of the explosive layer is, for example, 1 to 15 mg, preferably 3 to 10 mg, and more preferably about 5 to 8 mg. If the amount of ignitable component (powder component) is too small, the degree of combustion of the explosive layer (combustibility) may be reduced, and the smoker may feel less sucked. There is a risk that solidification will not be sufficient. On the other hand, if the amount is too large, excessive combustion and explosion may occur.

  The cylindrical ventilation part can be formed of at least a hollow cylindrical member. The hollow cylindrical member may be formed in a thin shape using a wrapping paper or a thin cylindrical member, or may be formed in a thick shape using a thick paper or a thick cylindrical member. In addition, since a cylindrical ventilation part can buffer that gas generated by rapid combustion of an explosive layer, combustion heat, and its expansion pressure (or pressure) are transmitted to a filter part, it can also function as a buffer part.

  The ventilation part of the cylindrical ventilation part may form a rectifying channel and / or a turbulent channel. The rectifying flow path is often formed as a straight flow path, and may be formed, for example, as a hollow portion, or by forming a breathable member capable of forming a straight flow path in the ventilation portion. Also good. This linear flow path (cavity) has a spiral cross-section formed by using a hollow air-permeable member such as a cylindrical body obtained by spirally winding a thin piece body (paper or the like) or a cylindrical body having a cross-sectional mesh shape ( Alternatively, it may be a spiral flow path, a cross-sectional mesh (or lattice) flow path, or the like.

  The turbulent flow path is formed of a breathable member that is disposed in the ventilation portion and can form an irregular (or random) flow path, a breathable filling layer in which the ventilation section is filled with a filler, and the like. May be. The air-permeable member capable of forming the turbulent flow path is, for example, a sheet-like shape in which an uneven portion (saddle portion) and / or a fractured portion (penetrated vent portion, etc.) are formed by embossing and / or creping. A spiral hollow cylindrical breathable member formed by winding a thin piece (paper or the like) may be used.

  The air-permeable member may be formed of, for example, wood, paper, glass, metal, plastic, or the like depending on the form of the rectifying channel and / or the turbulent channel.

  In FIG. 1, the example of the cigarette of this invention is shown. In this example, the cigarette 1 includes a cigarette part (or engraved part) 2, a filter part 3, a sheet-shaped explosive layer 4 having a circular cross section that is adjacent to the cigarette part 2 and includes nitrocellulose. It has a cylindrical ventilation part 6 interposed between the explosive layer 4 and the filter part 3 and whose outer peripheral part is formed of a main part wrapping paper 7. The main part wrapping paper 7 is composed of the cigarette part 2 and the explosive layer 4. An outer periphery is also formed. The diameter [phi] of the sheet-shaped explosive layer 4 is smaller than the diameter (about [phi] 8 to 10 mm) of the cigarette 1 (cigarette portion 2) for ventilation, and is formed, for example, to about [phi] 5 to 9 mm. A spiral paper (breathable member 5) is disposed over the entire length of the tubular vent 6 in the vent of the tubular vent 6, and the breathable member 5 is in contact with the tobacco portion 2. While holding the explosive layer 4, a rectifying flow path having a spiral cross section is formed. In addition, in order to connect the main body (the cigarette part 2, the explosive layer 4 and the cylindrical ventilation part 6) and the filter part 3, the filter part 3 is overlapped (overlapped) with the end part of the main body part wrapping paper 7. Covered with wrapping paper 8.

  In such a cigarette 1, when the explosive layer 4 is ignited, it suddenly burns and produces a sound, thereby improving the smoker's feeling of sucking. In addition, since the air-permeable member 5 is used to form a flow passage having a spiral cross section, the pressure loss (ventilation resistance) is relatively small, the buffering property of the combustion-generated gas can be improved, and the tobacco portion is brought into contact with it. The gunpowder layer 4 can be held. Further, since the explosive layer 4 is rapidly burned and solidified, it can be burned without leaving the tobacco leaf, and the fall off of the burnt tobacco leaf can be suppressed.

  If a turbulent flow path is formed in the ventilation portion, a short path of combustion generated gas can be prevented. In the example shown in FIG. 2, the cigarette 11 is the same as the cigarette 1 shown in FIG. 1 except that a breathable filling layer 15 is provided in the ventilation portion. That is, in order to hold the sheet-shaped explosive layer 4 adjacent to the cigarette part 2, the ventilation part of the cylindrical ventilation part 16 of the cigarette 11 is filled with quartz sand (granular filler), and quartz sand (granular filler). ) Filled layer (breathable packed layer) 15 forms a maze-like random flow path.

  In such a cigarette 11, since the breathable packed layer 15 is used, a flow path that is entangled (or irregular) in a labyrinth is formed, and a short path of gas generated by rapid combustion of the explosive layer 4 Can be effectively suppressed. Further, the gunpowder layer 4 can be reliably held, and even if the gunpowder layer 4 burns rapidly, the filter unit 3 may ignite because it is adjacent to the nonflammable breathable packed layer (or nonflammable layer) 15. In addition, heat conduction to the mouth of the filter unit 3 can be prevented, and safety can be improved. When the breathable packed layer 15 is formed of quartz sand (inorganic granular filler), at least the breathable packed layer 15 on the side of the explosive layer 4 is melted and fused and condensed due to rapid combustion of the explosive layer 4. In some cases, a solidified portion of the form can be formed. Therefore, the remaining tobacco leaf can be burned, and the tobacco leaf can be prevented from remaining in the tobacco portion (or engraved portion) 2, and the combustion of the burned tobacco leaf can be prevented in combination with the solidification of the explosive layer 4.

  The form of the filler may be granular, powdery, fibrous, etc. (particularly granular). Examples of fillers include metal oxides [silicon dioxide (quartz sand, silica sand, silica, diatomaceous earth, glass powder, etc.), alumina, iron oxide, etc.], metal hydroxides (such as aluminum hydroxide), metal carbonates. Examples thereof include inorganic fillers such as calcium carbonate and the like and silicates such as zeolite. These fillers can be used alone or in combination of two or more.

  The average particle diameter of the granular filler can be selected from a range of, for example, about 1 to 1000 μm, and is usually about 10 to 1000 μm, preferably 50 to 800 μm, and more preferably about 100 to 600 μm (for example, 200 to 500 μm). May be.

  In addition, the space ratio [the volume of the space with respect to the volume of the air-permeable filling layer (the volume excluding the filler)] of the cylindrical ventilation part in which the air-permeable filling layer is formed is, for example, 0.01 to 0.3, preferably It may be about 0.05 to 0.2, 0.2 to 0.7 (for example, 0.25 to 0.6), preferably 0.3 to 0.5, and more preferably 0.4 to It may be about 0.5. If the space ratio is too large, there is a possibility that the short path of the generated gas cannot be effectively suppressed, and conversely, if it is too small, the pressure loss (venting resistance) may be increased.

  The breathable member does not need to be disposed over the entire length of the ventilation portion, and may be partially disposed to partially form a hollow portion. Moreover, the ventilation part of a cylindrical ventilation part can also be arrange | positioned combining 1 or several air permeable members and / or an air permeable filling layer. For example, a mesh-shaped breathable member having a circular cross section may be provided adjacent to the explosive layer and held in the tobacco portion, and a breathable filling layer may be provided between the breathable member and the filter portion. In such a ventilation part, the rectifying channel and the turbulent channel can be combined.

  In addition, the length of the long axis direction of a cylindrical ventilation part should just be a range which does not impair buffer property, for example, 1-30% with respect to the length of the long axis direction of a cigarette, Preferably it is 5-20 % May be sufficient.

  Examples of the filter material forming the filter part include cellulose ester fibers (for example, cellulose ester fibers such as cellulose acetate and cellulose propionate), natural cellulose fibers (for example, wood pulp, seed hair fibers, etc.), and regenerated cellulose fibers. Examples thereof include cellulose fibers such as viscose rayon (for example, synthetic fibers such as polypropylene fibers). These fibers may be used alone or in combination of two or more. Of these fibers, cellulose ester fibers such as cellulose acetate, natural cellulose fibers such as wood pulp, and the like are preferable. In addition, the cross-sectional shape of the fiber is, for example, an irregular shape (for example, an X shape, a Y shape, an H shape, an I shape, an R shape, etc.) in order to improve the filterability of harmful components. it can. In addition, the fiber may be crimped, and the filterability (or removal rate) of harmful components can be further improved by using the crimped fiber.

  The filter part can also be formed of a sheet material made from the filter material (for example, natural cellulose fiber such as cellulose ester fiber or wood pulp). In particular, when a sheet material subjected to embossing and / or creping is used, gas filterability can be effectively improved. In addition, as a method for manufacturing the filter portion, the filter material is introduced into a filter rod molding die to form a filter rod, the sheet material is introduced into a filter plug hoisting machine, and is wound up or folded into a spiral shape. Examples include a method of using a filter rod.

  Furthermore, in order to prevent a smoker from inhaling the combustion gas from the explosive layer, the filter part may contain an adsorbent. Examples of the adsorbent include activated carbon, zeolite, alumina, silica gel, bentonite and the like. Among these adsorbents, activated carbon can be suitably used. The adsorbent may be fibrous, but may preferably be granular. Further, the adsorbent may be uniformly distributed in the filter part, or may be non-uniformly or partially present. When the adsorbent is partially distributed in the filter portion, it may be uniformly dispersed or filled at the end or center in the long axis direction. In addition, it may be partially unevenly distributed like a dual charcoal filter.

  The cigarette has a long cylindrical shape, the length in the major axis direction is usually about 60 to 100 mm (for example, 80 to 100 mm), and the diameter is usually 5 to 9 mm (for example, 7 to 7 mm). 9mm). Moreover, the pressure loss (air flow resistance) at an air flow rate of 17.5 ml / sec in a cigarette (length 85 mm and diameter 8 mm) is, for example, 200 to 1000 mmWG (water gauge), preferably 300 to 900 mmWG, more preferably 400 to It is about 800 mmWG.

  The present invention also includes a method for producing the cigarette. That is, in the cigarette manufacturing method including the cigarette part and the filter part, an explosive layer may be formed adjacent to the cigarette part, and a cylindrical ventilation part may be formed between the explosive layer and the filter part. For example, the cigarette shown in FIGS. 1 and 2 has a cigarette leaf, a gunpowder layer, and a spiral paper (breathable member) or quartz sand (granular filler) rolled up by a main body wrapping paper, and a main body part (cigarette part, explosive layer and cylinder). And the end part of the main body part wrapping paper and the filter part may be rolled up by using the filter part wrapping paper.

  Hereinafter, the present invention will be described in more detail based on examples, but the present invention is not limited to these examples.

Example 1
Using a commercially available tobacco “Peace Light Box” (made by Japan Tobacco Inc.), carefully squeeze all the tobacco leaves out of the tobacco column (tobacco section) without damaging the wrapping paper. Was saved for later refilling. Fill the tube-shaped cavity of the wrapping paper from which all the tobacco leaves have been scraped with 1 g of quartz sand (Kishida Chemical Co., Ltd., particle size 0.3 to 0.5 mm (30 to 50 mesh)). On top of this, three sheets of flash paper (seller: S & C Magic Co., Ltd.) cut into a circle with a diameter of 6 mm, which was air-dried at room temperature, were stacked (total weight of flash paper 6 mg). The stored cigarette leaf was filled to obtain a cigarette of the form shown in FIG. This cigarette is smoked with a piston-type constant-volume automatic smoker (manufactured by Borgwald, “RM20 / CS”) at a flow rate of 17.5 ml / second under the conditions of smoking time 2 seconds / time and smoking frequency 1 time / minute. As a result, the flash paper burned and pronounced at the end of smoking, producing a feeling of sucking up. Moreover, the gunpowder layer (flash paper) was carbonized and solidified, and the tobacco leaf was burned without remaining. In addition, the phenomenon (fusion) that the surface of quartz sand hardened occurred.

(Example 2)
A cigarette was prepared and smoked in the same manner as in Example 1 except that instead of flash paper, a mixture of 6 mg of nitrified cotton (Taihei Chemical Co., Ltd., “H1 / 16”) and 6 mg of scraped tobacco leaves was filled. Experiments were performed. At the end of smoking, the mixture of nitrified cotton and tobacco leaves burned, producing a feeling of sucking. Moreover, the gunpowder layer (flash paper) was carbonized and solidified, and the tobacco leaf was burned without remaining.

Example 3
Example 1 except that instead of quartz sand, a spiral cylinder having a length of 20 mm made of copy paper (“V-Paper”, basis weight 64 g / m ² , manufactured by Fuji Xerox Co., Ltd.) was used as a spacer. In the same manner, a cigarette having the form shown in FIG. 1 was prepared and a smoking experiment was conducted. The flash paper burned at the end of smoking, creating a feeling of sucking up.

(Comparative Example 1)
A cigarette was produced in the same manner as in Example 1 without filling the flash paper, and a smoking experiment was conducted. However, there was no noticeable change in combustion at the end of smoking, and it was impossible to produce a feeling of sucking up. In addition, tobacco leaves remained in the butts.

  Since the cigarette of this invention can implement | achieve a smoker's feeling of sucking, it is useful as a new sense cigarette. In addition, the tobacco leaf can be burned out and the powder layer can be solidified, so it is possible to prevent odors and dirt caused by the tobacco leaf, maintain the aesthetics and cleanliness of the ashtray, and easily collect the filter part. is there. Furthermore, since the tobacco leaf can be sucked up to the end portion, it is possible to reduce the wasteful waste tobacco leaf, which is useful for environmental conservation.
