以往，雖然已有提出一種可改變煙草製品之過濾特性或空氣導入比例的技術，但是結構複雜，且製造時有費時及花成本的問題。於是，本發明之目的係在於可藉由簡易的構成來變更煙草製品的過濾特性。 In the past, although a technique for changing the filtration characteristics or the air introduction ratio of a tobacco product has been proposed, the structure is complicated, and there are problems in that it is time consuming and costly to manufacture. Accordingly, it is an object of the present invention to modify the filtration characteristics of a tobacco product by a simple configuration.
本發明之一態樣的濾嘴，係沿著軸向設置有貫通孔的煙草製品用的濾嘴。又，在濾嘴之外周，係沿著圓周方向設置有狹縫(slit)；以狹縫為交界，將濾嘴之軸向的兩側相對地朝向相反方向沿著圓周方向扭轉，藉此使貫通孔的剖面積產生變化。 A filter according to an aspect of the present invention is a filter for a tobacco product in which a through hole is provided along an axial direction. Further, on the outer circumference of the filter, a slit is provided along the circumferential direction; and the slit is used as a boundary, and both sides of the axial direction of the filter are relatively twisted in the circumferential direction in the opposite direction, thereby The cross-sectional area of the through hole changes.
依據此，能隨著剖面積之變化而改變通氣阻力，且可使具備該濾嘴的煙草製品之過濾特性產生變化。亦即，可藉由簡易的構成來變更煙草製品的過濾特性。 According to this, the ventilation resistance can be changed in accordance with the change in the sectional area, and the filtration characteristics of the tobacco product having the filter can be changed. That is, the filtration characteristics of the tobacco product can be changed by a simple configuration.
又，本發明之另一態樣的煙草製品，係具有：濾嘴，為沿著軸向設置有貫通孔的濾嘴，且在該濾嘴之外周沿著圓周方向設置有狹縫，以狹縫為交界，將濾嘴之軸向的兩側相對地朝向相反方向沿著圓周方向扭轉，藉此使貫通孔的剖面積產生變化；外層紙(tip paper)，係包覆濾嘴的至少一部分；以及煙桿(cigarette rod)，其含有煙絲，且透過外層紙與濾嘴連接。據此，能隨著剖面積之變化而改變通氣阻力，亦能使煙草製品的過濾特性產生變化。亦即，可藉由簡易的構成來變更煙草製品的過濾特性。 Further, a tobacco product according to another aspect of the present invention includes: a filter having a filter having a through hole provided in the axial direction, and a slit provided in the circumferential direction outside the filter to narrow The slit is a boundary, and the axial sides of the filter are relatively twisted in opposite directions in the circumferential direction, thereby changing the sectional area of the through hole; the tip paper is covering at least a part of the filter And a cigarette rod containing cut tobacco and connected to the filter through the outer paper. Accordingly, the ventilation resistance can be changed as the sectional area changes, and the filtration characteristics of the tobacco product can also be changed. That is, the filtration characteristics of the tobacco product can be changed by a simple configuration.
又，外層紙亦可沿著煙草製品之圓周方向具有切縫(cut line)或打孔眼線(perforation)，比該切縫或打孔眼線更靠近煙桿側的部分係與濾嘴中之比狹縫更靠近煙桿側的部分連接，外層紙中之比切縫或打孔眼線更靠近吸口側的部分係與濾嘴中之比狹縫更靠近吸口側的部分連接。依據此，與濾嘴中之比狹縫更靠近煙絲側的部分連接的外層紙、及與濾嘴中之靠近吸口側的部分連接的外層紙，就能以切縫為交界而彼此地朝向相反方向轉動。 Further, the outer layer paper may have a cut line or a perforation along the circumferential direction of the tobacco product, and the portion closer to the tobacco rod side than the slit or perforated eye line is compared with the filter. The slit is closer to the side of the tobacco rod side, and the portion of the outer paper that is closer to the suction side than the slit or perforated eye is connected to the portion of the filter that is closer to the suction side than the slit. According to this, the outer paper which is connected to the portion of the filter which is closer to the tobacco side than the slit, and the outer paper which is connected to the portion of the filter which is close to the suction side, can be opposite to each other with the slit as the boundary. The direction is rotated.
又，外層紙亦可在比濾嘴之狹縫更靠近吸口側之處具有通氣孔。依據此，能隨著濾嘴之貫通孔的剖面積之變化，而改變使用者吸嘗煙草製品時之來自通氣孔的空氣導入比例。 Further, the outer layer paper may have a vent hole at a position closer to the suction port than the slit of the filter. According to this, the air introduction ratio from the vent hole when the user sucks the tobacco product can be changed in accordance with the change in the sectional area of the through hole of the filter.
又，煙草製品亦可在比狹縫更靠近煙桿側之處，保持包含呈味成分或香料成分的香味源。依據此，可提供一種藉由扭轉濾嘴就能夠變更呈味成分或香料成分之釋出量的煙草製品。 Further, the tobacco product may hold a flavor source containing a flavor component or a flavor component at a position closer to the tobacco rod than the slit. According to this, it is possible to provide a tobacco product which can change the release amount of the flavor component or the flavor component by twisting the filter.
另外，用以解決本發明之課題的手段，係可儘可能地組合在一起來採用。 Further, means for solving the problems of the present invention can be employed as much as possible in combination.
依據本發明，可藉由簡易的構成來變更煙草製品的過濾特性。 According to the present invention, the filtration characteristics of the tobacco product can be changed by a simple configuration.

第1圖係顯示煙草製品之一例的濾嘴香煙(紙煙，亦簡 稱為「香煙」)的分解立體圖。香煙1係成形為大致圓柱形狀。在本實施形態中，係將香煙1之長度方向稱為軸向，亦將曲面稱為側面。香煙1係包含煙桿11、中心孔(CH)濾嘴12及醋酸纖維濾嘴(acetate filter)13。煙桿11係利用捲紙來包覆煙葉之切絲(亦稱為「煙絲」)者。CH濾嘴12係沿著大致圓柱形狀的濾嘴之軸向，在橫剖面的大致中心設置有貫通孔(中心孔)121的圓筒狀之濾嘴。又，在CH濾嘴12之軸向中央附近的外周，係沿著圓周方向且遍及於全周地設置有屬於非貫通之切縫的狹縫122。CH濾嘴12係與一般的濾嘴同樣，可在醋酸纖維(acetate fiber)添加可塑劑而成形，且用原料紙(未圖示)來包覆側面外周。另外，狹縫122係從原料紙的上方設置。又，醋酸纖維濾嘴13係由醋酸纖維成形為圓柱形狀之一般的濾嘴。 Figure 1 shows a filter cigarette (paper cigarette, also simple) An exploded perspective view of a "cigarette". The cigarette 1 is formed into a substantially cylindrical shape. In the present embodiment, the longitudinal direction of the cigarette 1 is referred to as an axial direction, and the curved surface is also referred to as a side surface. The cigarette 1 includes a tobacco rod 11, a center hole (CH) filter 12, and an acetate filter 13. The tobacco rod 11 is a person who uses a roll of paper to cover the shredded tobacco (also referred to as "cut tobacco"). The CH filter 12 is a cylindrical filter having a through hole (central hole) 121 at the approximate center of the cross section along the axial direction of the substantially cylindrical filter. Further, a slit 122 belonging to a non-penetrating slit is provided on the outer circumference of the CH filter 12 in the vicinity of the center in the axial direction in the circumferential direction and over the entire circumference. Similarly to a general filter, the CH filter 12 can be formed by adding a plasticizer to an acetate fiber, and covering the outer periphery of the side surface with a raw material paper (not shown). Further, the slit 122 is provided from above the raw material paper. Further, the cellulose acetate filter 13 is a general filter formed of cellulose acetate into a cylindrical shape.
CH濾嘴12和醋酸纖維濾嘴13係鄰接配置於軸向並且用成型紙14來包覆側面外周，且成形為圓柱形狀。在成型紙14中，係在比狹縫122更靠近香煙1之軸向的煙絲側之處設置有切縫141。另外，成型紙14係在成型紙14之端部彼此所疊合的部分塗覆有接著劑(未圖示)並予以貼合，並且亦在內周之一部分沿著軸向塗覆有接著劑(未圖示)，來與CH濾嘴12及醋酸纖維濾嘴13接著。 The CH filter 12 and the cellulose acetate filter 13 are disposed adjacent to each other in the axial direction, and are covered with the molding paper 14 to cover the outer periphery of the side surface, and are formed into a cylindrical shape. In the molded paper 14, a slit 141 is provided at a side of the tobacco which is closer to the axial direction of the cigarette 1 than the slit 122. Further, the molded paper 14 is coated with an adhesive (not shown) at a portion where the end portions of the molded paper 14 are overlapped with each other, and is also coated with an adhesive in one axial direction in the inner peripheral portion. (not shown), it is followed by the CH filter 12 and the cellulose acetate filter 13.
又，煙桿11和CH濾嘴12及醋酸纖維濾嘴13，係鄰接配置於軸向並且用外層紙15來包覆側面外周，且成形為圓柱形狀。在外層紙15中，係在香煙1之軸向比狹縫122更靠近煙絲側之處設置有切縫151，而在比狹縫 122更靠近吸口側(即醋酸纖維濾嘴13側)之處，係設置有作為香煙1之使用者在吸嘗時用以導入空氣之貫通孔的供氣部(亦稱為「通氣孔」)152。供氣部152係指將用以稀釋主流煙的空氣從外部導入至濾嘴內的導入口。具體而言，供氣部152係藉由遍及CH濾嘴12之全周設置複數個點(dot)狀之孔所構成。另外，外層紙15亦能用接著劑來貼合濾嘴頭15之端部彼此所疊合的部分，並且亦在內周之一部分沿著軸向塗覆有接著劑(未圖示)，來與煙桿11和CH濾嘴12及醋酸纖維濾嘴13接著。 Further, the tobacco rod 11 and the CH filter 12 and the cellulose acetate filter 13 are disposed adjacent to each other in the axial direction, and are covered with the outer layer 15 to cover the outer circumference of the side surface, and are formed into a cylindrical shape. In the outer layer paper 15, a slit 151 is provided in the axial direction of the cigarette 1 closer to the tobacco side than the slit 122, and in the slit 122 is closer to the mouth side (ie, the side of the cellulose acetate filter 13), and is provided with a gas supply portion (also referred to as a "vent hole") for introducing a through hole of air as a user of the cigarette 1 during suction. 152. The air supply portion 152 is an introduction port that introduces air for diluting the mainstream smoke from the outside into the filter. Specifically, the air supply unit 152 is configured by providing a plurality of dot-shaped holes throughout the entire circumference of the CH filter 12. Further, the outer layer paper 15 can also be attached with an adhesive to the portion where the end portions of the filter head 15 overlap each other, and also an adhesive (not shown) is applied along one of the inner circumferences in the axial direction. It is followed by the tobacco rod 11 and the CH filter 12 and the cellulose acetate filter 13.
第2圖係用以說明CH濾嘴12之變形的立體圖。如第2圖之箭頭所示，本實施形態的CH濾嘴12係將狹縫122之軸向上的兩側，沿著圓周方向相互地朝向相反方向扭轉，藉此可使橫剖面的形狀產生變化。亦即，藉由扭轉CH濾嘴12，剪斷應力就會集中於設置有狹縫122的部分，使得設置有狹縫122的部分被擰緊並使貫通孔121之內徑變小，藉此可使貫通孔121閉塞。如此，CH濾嘴12，就可藉由簡易的構成來使CH濾嘴12之通氣阻力產生變化，且變更從供氣部152所導入的空氣之比率(空氣導入比例)。另外，CH濾嘴12亦可在被扭轉時，使設置有狹縫122的部分之外徑不變化、或變化。 Fig. 2 is a perspective view for explaining the deformation of the CH filter 12. As shown by the arrow in Fig. 2, the CH filter 12 of the present embodiment twists both sides in the axial direction of the slit 122 in the circumferential direction in the opposite direction, whereby the shape of the cross section can be changed. . That is, by twisting the CH filter 12, the shear stress concentrates on the portion where the slit 122 is provided, so that the portion where the slit 122 is provided is tightened and the inner diameter of the through hole 121 is made small, whereby The through hole 121 is closed. As described above, the CH filter 12 can change the ventilation resistance of the CH filter 12 by a simple configuration, and change the ratio of the air introduced from the air supply unit 152 (air introduction ratio). Further, the CH filter 12 may not change or change the outer diameter of the portion where the slit 122 is provided when it is twisted.
第3圖係示意性地顯示香煙1的縱剖視圖。在第3圖中，係為了強調顯現外層紙等捲紙之厚度，並且強調並未接著的部分而保持有間隙。香煙1係具有複數個排列於軸向之作為性質不同之區域的區段。具體而言，香 煙1係具有：煙桿區段110，係具備煙桿11；中心孔(CH)區段120(120a及120b)，係具備具有貫通孔121的CH濾嘴12；以及吸口側之醋酸纖維濾嘴區段130，係具備醋酸纖維濾嘴13。另外，在CH濾嘴12之軸向的大致中央係設置有狹縫122，在第3圖之例中，狹縫122的兩側係被分成煙絲側部分120a和吸口側部分120b。又，如第1圖所示，在成型紙14中，遍及側面之全周設置有切縫141，而在外層紙15中，遍及側面之全周設置有切縫151。 Fig. 3 is a longitudinal sectional view schematically showing the cigarette 1. In Fig. 3, in order to emphasize the thickness of the roll paper such as the outer layer paper, and to emphasize the portion which is not continued, a gap is maintained. The cigarette 1 has a plurality of sections arranged in the axial direction as regions having different properties. Specifically, incense The cigarette 1 has a tobacco rod section 110 having a tobacco rod 11 and a central hole (CH) section 120 (120a and 120b) having a CH filter 12 having a through hole 121; and a cellulose acetate filter on the suction side The mouth section 130 is provided with a cellulose acetate filter 13. Further, a slit 122 is provided substantially in the center of the axial direction of the CH filter 12, and in the example of Fig. 3, both sides of the slit 122 are divided into a tobacco side portion 120a and a suction side portion 120b. Further, as shown in Fig. 1, in the molded paper 14, a slit 141 is provided over the entire circumference of the side surface, and in the outer paper 15, a slit 151 is provided over the entire circumference of the side surface.
又，第3圖係在成型紙14與CH濾嘴12及醋酸纖維濾嘴13之間、以及外層紙15與煙桿11及成型紙14之間分別顯示接著劑142及接著劑153。接著劑142及接著劑153，係塗覆於圓周方向之一部分。又，配合成型紙14之切縫141及外層紙15之切縫151而在軸向之一部分係存在有並未遍及於全周塗覆有接著劑142及接著劑153的部分。亦即，狹縫122係遍及於側面之全周與外層紙15之切縫151連通。換言之，成型紙14中之沿著圓周方向而設置的切縫141之煙絲側的部分，係與CH濾嘴12之比狹縫122更靠近煙絲側的部分接著，而成型紙14中之比切縫141更靠近吸口側的部分，係與CH濾嘴12之比狹縫122更靠近吸口側的部分接著。同樣地，外層紙15中之沿著圓周方向而設置的切縫151之煙絲側的部分，係透過成型紙14間接地與CH濾嘴12之比狹縫122更靠近煙絲側的部分接著，而外層紙15中之比切縫151更靠近吸口側的部分，係透過成型14間接地與CH濾嘴12之比狹縫122 更靠近吸口側的部分接著。在此，當狹縫122之煙絲側部分120a和吸口側部分120b透過成型紙14或外層紙15來連接時，就會在使用者扭轉CH濾嘴12時妨礙轉動。在本實施形態中，係藉由設置成型紙14之切縫141及外層紙15之切縫151，來將成型紙14及外層紙15分別地分成與狹縫122之煙絲側連接的部分、及與吸口側連接的部分，且煙絲側部分120a和吸口側部分120b可相對地轉動。 Further, in the third drawing, the adhesive 142 and the adhesive 153 are respectively displayed between the molded paper 14 and the CH filter 12 and the cellulose acetate filter 13, and between the outer paper 15 and the tobacco rod 11 and the molded paper 14. The adhesive 142 and the adhesive 153 are applied to one of the circumferential directions. Further, in the slit 141 of the molded paper 14 and the slit 151 of the outer paper 15, a portion which is not coated with the adhesive 142 and the adhesive 153 throughout the entire circumference is present in one of the axial directions. That is, the slit 122 communicates with the slit 151 of the outer layer paper 15 over the entire circumference of the side surface. In other words, the portion on the tobacco side of the slit 141 provided in the circumferential direction of the molded paper 14 is adjacent to the portion of the CH filter 12 which is closer to the tobacco side than the slit 122, and the ratio in the molding paper 14 is cut. The portion of the slit 141 closer to the suction port side is followed by a portion of the CH filter 12 closer to the suction port side than the slit 122. Similarly, the portion of the outer layer paper 15 on the tobacco side of the slit 151 which is disposed along the circumferential direction is indirectly passed through the molding paper 14 to the portion of the CH filter 12 which is closer to the tobacco side than the slit 122, and The portion of the outer paper 15 that is closer to the suction side than the slit 151 is indirectly penetrated by the molding 14 to the slit 122 of the CH filter 12 The portion closer to the suction side is followed. Here, when the cut tobacco side portion 120a and the suction port side portion 120b of the slit 122 are connected by the molding paper 14 or the outer layer paper 15, the rotation is hindered when the user twists the CH filter 12. In the present embodiment, the slit paper 141 of the molded paper 14 and the slit 151 of the outer paper 15 are provided, and the molded paper 14 and the outer paper 15 are respectively divided into portions connected to the tobacco side of the slit 122, and The portion connected to the mouth side, and the tobacco side portion 120a and the mouth side portion 120b are relatively rotatable.
又，在外層紙15係設置有供氣部152。如第3圖所示，在貫通孔121並未被擰緊的狀態下，貫通孔121之通氣阻力較低，且如一點鏈線之粗箭頭所示，從貫通孔121朝向吸口側導入的空氣係比從供氣部152朝向吸口側導入的空氣更多。 Further, the outer layer paper 15 is provided with an air supply portion 152. As shown in FIG. 3, in the state in which the through hole 121 is not tightened, the ventilation resistance of the through hole 121 is low, and the air system introduced from the through hole 121 toward the suction port side is indicated by a thick arrow of a little chain line. More air is introduced from the air supply portion 152 toward the suction port side.
第4圖係顯示將香煙1之CH區段120扭轉後之狀態的示意性剖視圖。在第4圖之例中，CH區段120之煙絲側部分120a和吸口側部分120b係相互地朝向相反方向扭轉，且在交界的狹縫122部分，CH濾嘴12之橫剖面的直徑及其內部之貫通孔121的內徑係比第3圖所示的狀態更小。此時，貫通孔121之通氣阻力係比第3圖所示的狀態更提高。從而，如第4圖之一點鏈線的箭頭所示，從貫通孔121導入的空氣之導入量，係比第3圖所示的狀態更減少。另一方面，從供氣部152導入的空氣之導入量，係比第3圖所示的狀態更增大。 Fig. 4 is a schematic cross-sectional view showing a state in which the CH section 120 of the cigarette 1 is twisted. In the example of Fig. 4, the tobacco side portion 120a and the mouth side portion 120b of the CH section 120 are twisted toward each other in opposite directions, and the diameter of the cross section of the CH filter 12 at the portion of the slit 122 at the boundary and The inner diameter of the inner through hole 121 is smaller than the state shown in Fig. 3 . At this time, the ventilation resistance of the through hole 121 is higher than the state shown in FIG. Therefore, as indicated by the arrow of the dot chain line in FIG. 4, the amount of introduction of air introduced from the through hole 121 is reduced more than the state shown in FIG. On the other hand, the introduction amount of the air introduced from the air supply unit 152 is larger than the state shown in FIG.
第5圖係顯示將香煙1之CH區段120更進一步扭轉後之狀態的示意性剖視圖。在第5圖之例中，CH 濾嘴12之橫剖面的直徑及其內部之貫通孔121的內徑係比第4圖所示的狀態更小，在此係顯示藉由扭轉而使貫通孔完全閉塞的狀態。此時，貫通孔121之通氣阻力係比第4圖所示的狀態更進一步提高。從而，如第5圖之一點鏈線的箭頭所示，從貫通孔121導入的空氣之導入量，係比第4圖所示的狀態更進一步減少，而從供氣部152導入的空氣之導入量，係比第4圖所示的狀態更進一步增大。 Fig. 5 is a schematic cross-sectional view showing a state in which the CH section 120 of the cigarette 1 is further twisted. In the example of Figure 5, CH The diameter of the cross section of the filter 12 and the inner diameter of the through hole 121 therein are smaller than those shown in Fig. 4, and the through hole is completely closed by twisting. At this time, the ventilation resistance of the through hole 121 is further improved than the state shown in FIG. Therefore, as indicated by the arrow of the dot chain line in FIG. 5, the introduction amount of the air introduced from the through hole 121 is further reduced than the state shown in FIG. 4, and the introduction of the air introduced from the air supply portion 152 is introduced. The amount is further increased than the state shown in Fig. 4.
如以上所述，本實施形態的香煙1之CH濾嘴12，係藉由扭轉來使內部之貫通孔121的剖面積產生變化。又，可隨著該變化而改變通氣阻力，亦能使來自供氣部152的空氣導入量產生變化。亦即，因可藉由簡易的構成來變更煙草製品的空氣導入比例，又可使通過CH濾嘴內的主流煙通過濾嘴材料部分、或通過空洞部分、或使其變化，故而可變更尼古丁(nicotine)或焦油(tar)的過濾率。 As described above, in the CH filter 12 of the cigarette 1 of the present embodiment, the cross-sectional area of the inner through hole 121 is changed by twisting. Further, the ventilation resistance can be changed in accordance with the change, and the amount of introduction of air from the air supply portion 152 can also be changed. That is, since the air introduction ratio of the tobacco product can be changed by a simple configuration, the mainstream smoke passing through the CH filter can be changed through the filter material portion, or through the cavity portion, or can be changed, so that the nicotine can be changed ( Nicotine) or tar (tar) filtration rate.
第6圖係顯示內部具備香味源的香煙之一例的縱剖視圖。在實施形態2中，係在貫通孔121之內部具備粉末球(powder ball)16。所謂粉末球，係指將包含呈味成分和香料成分中之至少任一成分的原料粉末形成一塊的含粉末物質，並藉由施加外力而成為粉末者。又，粉末係當使用者進行吸嘗時就會通過貫通孔121而導入至使用者之口腔內。使用者係擠壓香煙1以將內部的粉末球16形成粉末狀，且藉由吸嘗粉末，即可獲得味道或香氣、或是該兩者。 本實施形態的香煙1係藉由使貫通孔121之內徑產生變化來使通氣阻力改變，同時亦使粉末對使用者之口腔的釋出量產生變化。另外，該種粉末球係可使用既有的技術來製造。 Fig. 6 is a longitudinal sectional view showing an example of a cigarette having a flavor source therein. In the second embodiment, a powder ball 16 is provided inside the through hole 121. The powder ball refers to a powdery substance which is formed by forming a raw material powder containing at least one of a taste component and a flavor component, and is powdered by applying an external force. Further, the powder is introduced into the oral cavity of the user through the through hole 121 when the user performs the suction. The user squeezes the cigarette 1 to form the inner powder ball 16 into a powder form, and by sucking the powder, a taste or aroma, or both can be obtained. In the cigarette 1 of the present embodiment, the ventilation resistance is changed by changing the inner diameter of the through hole 121, and the amount of release of the powder to the oral cavity of the user is also changed. In addition, the powder ball system can be manufactured using existing techniques.
在實施形態2中，係在煙桿11與CH濾嘴12之間配置有醋酸纖維濾嘴13。依據如此，就可防止煙絲朝向貫通孔121內移動，或防止粉末球16之粉末朝向煙桿11內移動。又，使用者所叼著的吸口側之端部，係使CH濾嘴12之貫通孔121呈開口狀態。另外，如第6圖所示，在製品的初期狀態下，貫通孔121係呈閉塞狀態，且粉末球16或其粉末並未溢出至香煙1之外部。 In the second embodiment, the cellulose acetate filter 13 is disposed between the tobacco rod 11 and the CH filter 12. According to this, it is possible to prevent the shredded tobacco from moving toward the inside of the through hole 121 or to prevent the powder of the powder ball 16 from moving toward the inside of the tobacco rod 11. Further, the end portion of the suction port side that the user rubs is such that the through hole 121 of the CH filter 12 is opened. Further, as shown in Fig. 6, in the initial state of the product, the through hole 121 is in a closed state, and the powder ball 16 or its powder does not overflow to the outside of the cigarette 1.
第7圖係顯示將香煙1之CH區段120扭轉後之狀態的示意性剖視圖。亦即，第7圖係顯示第6圖所示的CH區段120之煙絲側部分120a和吸口側部分120b互為相反方向，且朝向貫通孔121之內徑打開的方向被扭轉後的狀態。而且，在第7圖中，係在交界的狹縫122部分，使CH濾嘴12之橫剖面的直徑及其內部之貫通孔121的內徑比第6圖所示的狀態更大。又，在第7圖中，粉末球16係被壓扁而成為粉末16a。然後，當使用者進行吸嘗時，粉末16a就如第6圖所示地通過貫通孔121內且朝向使用者之口腔移動。 Fig. 7 is a schematic cross-sectional view showing a state in which the CH section 120 of the cigarette 1 is twisted. In other words, Fig. 7 shows a state in which the cut tobacco side portion 120a and the suction port side portion 120b of the CH section 120 shown in Fig. 6 are opposite to each other and are twisted in a direction in which the inner diameter of the through hole 121 is opened. Further, in Fig. 7, in the portion of the slit 122 at the boundary, the diameter of the cross section of the CH filter 12 and the inner diameter of the through hole 121 therein are larger than those shown in Fig. 6. Further, in Fig. 7, the powder ball 16 is crushed to become the powder 16a. Then, when the user performs the suction, the powder 16a passes through the through hole 121 as shown in Fig. 6 and moves toward the oral cavity of the user.
如以上所述，實施形態2的香煙1之CH濾嘴12，亦可藉由扭轉來使通氣阻力及過濾率產生變化。藉此，可使來自供氣部152的空氣導入量產生變化，並且可 使貫通孔121內之物理性的粉末之移動量產生變化。 As described above, in the CH filter 12 of the cigarette 1 of the second embodiment, the ventilation resistance and the filtration rate can be changed by twisting. Thereby, the amount of air introduced from the air supply portion 152 can be changed, and The amount of movement of the physical powder in the through hole 121 is changed.
雖然在第6圖及第7圖中已例示粉末球16，但是香煙1亦可保持作為內含液體狀之香料成分的膠囊(capsule)狀之香味源的香料膠囊(未圖示)。使用者係從香煙1之外側進行擠壓等而對香料膠囊施加外力，藉此可破壞香料膠囊。又，當香料膠囊被破壞時就能釋出內部的香料成分，而在CH濾嘴12受載有香料成分。然後，香料成分之至少一部分會氣化或霧(aerosol)化，使用者係可藉由吸嘗此香料成分而感覺香味。在此情況下，使用者係藉由扭轉CH濾嘴12來使通氣阻力產生變化，且使來自CH濾嘴12的空氣導入量(即通過CH濾嘴12內之受載有香料成分的部分所導入的空氣之量)產生變化，藉此可使吸氣中所含的香料成分之量產生變化。另外，如此的香料膠囊亦可使用既有的技術來製造。 Although the powder ball 16 has been exemplified in FIGS. 6 and 7, the cigarette 1 can also hold a flavor capsule (not shown) as a capsule-like flavor source containing a liquid flavor component. The user applies an external force to the fragrance capsule by pressing or the like from the outer side of the cigarette 1, whereby the fragrance capsule can be destroyed. Further, when the fragrance capsule is broken, the internal fragrance component is released, and the CH filter 12 is loaded with the fragrance component. Then, at least a portion of the flavoring component is vaporized or aerosolized, and the user can feel the flavor by absorbing the flavoring component. In this case, the user changes the ventilation resistance by twisting the CH filter 12, and the amount of air introduced from the CH filter 12 (i.e., through the portion of the CH filter 12 loaded with the fragrance component) The amount of air introduced is changed, whereby the amount of the flavor component contained in the inhalation can be changed. Additionally, such perfume capsules can also be made using established techniques.
又，如粉末球16或香料膠囊的香味源，並非是保持在CH濾嘴12之貫通孔121內，而是亦可保持在由外層紙或成型紙等所包覆之屬於空洞部分的空腔內。第8圖係顯示具有用以保持香味源的空腔的香煙之一例的示意性剖視圖。在第8圖之例中，係在第6圖及第7圖所示之香煙1的醋酸纖維濾嘴13與CH濾嘴12之間，具有由成型紙14或外層紙15等所包覆的屬於空洞區域的空腔區段(cavity segment)160。然後，在空腔區段160，係保持有粉末球16。如同上述般，在空腔內，亦可使其保持香料膠囊以取代粉末球16。在使其保持香料膠囊的情況下，亦可 採用相應於香料膠囊所內含的香料之性質而具有耐水性或耐油性的素材，作為成型紙14或外層紙15。又，在實施形態2中，亦可不設置外層紙15的供氣部152。 Further, the flavor source such as the powder ball 16 or the fragrance capsule is not held in the through hole 121 of the CH filter 12, but may be held in a cavity which is covered by the outer layer paper or the molding paper or the like. Inside. Fig. 8 is a schematic cross-sectional view showing an example of a cigarette having a cavity for holding a flavor source. In the example of Fig. 8, the cellulose acetate filter 13 and the CH filter 12 of the cigarette 1 shown in Figs. 6 and 7 are covered with a molding paper 14 or an outer paper 15 or the like. A cavity segment 160 belonging to the void area. Then, in the cavity section 160, a powder ball 16 is held. As in the above, it is also possible to hold the perfume capsule in place of the powder ball 16 in the cavity. In the case of keeping the capsules in the fragrance, As the molded paper 14 or the outer layer paper 15, a material having water resistance or oil resistance corresponding to the nature of the perfume contained in the perfume capsule is used. Further, in the second embodiment, the air supply portion 152 of the outer layer paper 15 may not be provided.
第9圖係顯示具有第8圖所示之空腔的香煙1之製造方法的示意圖。首先，藉由具備用以形成濾嘴之外徑的圓筒狀之空隙、以及用以在濾嘴設置貫通孔之屬於夾具的芯模(mandrel)的熱成形裝置(未圖示)，來形成沿著軸向而在橫剖面之大致中心具有貫通孔的CH濾嘴12。又，已形成為連續之桿狀的CH濾嘴12，係如一點鏈線所示，例如被切斷成製品之濾嘴的二倍之長度(步驟S1)。之後，一邊使CH濾嘴12朝向圓周方向旋轉，一邊在其周圍用旋轉刀具(rotary cutter)置入狹縫122(步驟S2)。又，將CH濾嘴12供給至作為濾嘴之製造裝置的組合器(combiner)(未圖示)。然後，CH濾嘴12係與如上所述的粉末球16及醋酸纖維濾嘴13並排配置，且用成型紙14包裝成一體(步驟S3)。另外，在成型紙14設置有切縫141。之後，由成型紙14所包裝的醋酸纖維濾嘴13、包含粉末球16的空腔以及CH濾嘴12所構成的濾嘴部分，係如一點鏈線所示，被切斷成使吸口側之端部彼此已結合的形狀。然後，配置有已與兩端之醋酸纖維濾嘴13鄰接的煙桿11，且在用外層紙15包裝之後，如一點鏈線所示，能藉由切斷軸向之中央而形成1根香煙1(步驟S4)。另外，在外層紙15，係設置有 切縫151。另外，在將已置入狹縫122的CH濾嘴12供給至組合器之前進行扭轉且形成完全閉塞貫通孔的狀態，藉此亦可防止製造時的粉末球之粉末的洩漏。 Fig. 9 is a schematic view showing a method of manufacturing the cigarette 1 having the cavity shown in Fig. 8. First, it is formed by a thermoforming device (not shown) having a cylindrical cavity for forming the outer diameter of the filter and a mandrel for attaching the through hole to the filter. The CH filter 12 having a through hole at substantially the center of the cross section along the axial direction. Further, the CH filter 12 which has been formed into a continuous rod shape is twice as long as the filter of the product, as shown by a one-dot chain line (step S1). Thereafter, while the CH filter 12 is rotated in the circumferential direction, the slit 122 is placed around the rotary cutter by a rotary cutter (step S2). Further, the CH filter 12 is supplied to a combiner (not shown) as a manufacturing apparatus of the filter. Then, the CH filter 12 is disposed side by side with the powder ball 16 and the cellulose acetate filter 13 as described above, and is integrally packaged by the molding paper 14 (step S3). Further, a slit 141 is provided in the molded paper 14. Thereafter, the cellulose acetate filter 13 packaged by the molded paper 14, the cavity including the powder ball 16 and the filter portion formed of the CH filter 12 are cut so as to be on the suction side as indicated by a one-dot chain line. The shape in which the ends are combined with each other. Then, the tobacco rod 11 which has been adjacent to the cellulose acetate filter 13 at both ends is disposed, and after being packaged with the outer paper 15, as shown by a chain line, a cigarette can be formed by cutting the center of the axial direction. 1 (step S4). In addition, the outer paper 15 is provided with Slit 151. In addition, the state in which the CH filter 12 placed in the slit 122 is supplied to the combiner is twisted and the through-hole is completely closed, thereby preventing leakage of the powder of the powder ball at the time of manufacture.
在實施形態1中，亦可將CH濾嘴12和醋酸纖維濾嘴13，配置成相反。亦即，如第6圖所示，香煙1亦可形成為以下的構成：在吸口側具備CH濾嘴12，在CH濾嘴12與煙桿11之間具備醋酸纖維濾嘴。又，亦可形成為以下的構成：在CH濾嘴12之兩側各具備一個醋酸纖維濾嘴13。即便是此等的構成，仍可變更香煙1之空氣導入比例或過濾率。 In the first embodiment, the CH filter 12 and the cellulose acetate filter 13 may be arranged to be opposite. In other words, as shown in Fig. 6, the cigarette 1 may be configured to include a CH filter 12 on the suction side and a cellulose acetate filter between the CH filter 12 and the tobacco rod 11. Further, a configuration may be adopted in which one acetate filter 13 is provided on each side of the CH filter 12. Even with such a configuration, the air introduction ratio or the filtration rate of the cigarette 1 can be changed.
又，在實施形態或變化例中，切縫141及切縫151之至少任一個，亦可為所謂的打孔眼線。當使用者扭轉CH濾嘴12時，就沿著打孔眼線切離而形成切縫141或切縫151，而CH濾嘴12之煙絲側部分120a和吸口側部分120b係朝向相反方向轉動。只要採用如此的成型紙14或外層紙15，就可在製造時作為一體的捲紙來進行包裝，且可依需要而切離。同樣地，切縫141或切縫151亦可事先切離，且使切縫之端部相互地疊合。 Further, in the embodiment or the modification, at least one of the slit 141 and the slit 151 may be a so-called perforated eyeliner. When the user twists the CH filter 12, the slit 141 or the slit 151 is formed by cutting along the perforated eye line, and the cut tobacco side portion 120a and the suction side portion 120b of the CH filter 12 are rotated in opposite directions. As long as such a formed paper 14 or outer layer paper 15 is used, it can be packaged as an integral roll paper at the time of manufacture, and can be cut away as needed. Similarly, the slit 141 or the slit 151 can also be cut away in advance, and the ends of the slits are overlapped with each other.
又，切縫141或切縫151、與狹縫122之相對的位置並未被限定於上述之例。例如，如第10圖所示，切縫141及切縫151亦可設置於大致狹縫122上。如此，就可在已捲繞成型紙14或外層紙15的狀態下集中形成狹 縫122，且可減少耗費在製造上的工時。又，與供氣部152同樣地，亦可從狹縫122導入外部空氣。另一方面，因CH濾嘴12之狹縫122周邊係藉由使用者扭轉而使醋酸纖維之密度產生變化，故在從狹縫122導入外部空氣的情況下，將很難設計該量。從而，如第3圖等所示，在提升來自供氣部152之空氣導入量的精確度方面，較佳是將切縫141或切縫151和狹縫122在軸向進行偏移設置。另外，切縫141或切縫151亦可在軸向設置在比狹縫122更靠近吸口側之處。 Further, the position where the slit 141 or the slit 151 and the slit 122 face each other is not limited to the above example. For example, as shown in FIG. 10, the slit 141 and the slit 151 may be provided on the substantially slit 122. Thus, it is possible to form a narrow portion in a state in which the molded paper 14 or the outer paper 15 has been wound. The slit 122 is used, and the labor for manufacturing is reduced. Further, similarly to the air supply unit 152, outside air can be introduced from the slit 122. On the other hand, since the density of the cellulose acetate is changed by the twist of the user around the slit 122 of the CH filter 12, it is difficult to design the amount when the outside air is introduced from the slit 122. Therefore, as shown in FIG. 3 and the like, in terms of improving the accuracy of the air introduction amount from the air supply portion 152, it is preferable to offset the slit 141 or the slit 151 and the slit 122 in the axial direction. Further, the slit 141 or the slit 151 may be disposed in the axial direction closer to the suction side than the slit 122.
又，CH濾嘴12之貫通孔121係從橫剖面來觀察，亦可設置於偏離中心的位置。但是，在CH濾嘴12之大致中央設置有貫通孔121，使用者將更容易地扭轉CH濾嘴12。又，作為非貫通之溝槽的狹縫122之遍及全周的深度，既可為固定，亦可有偏差。例如，第11圖係以第3圖所示之A-A線切斷後的A-A剖視圖之一例。具體而言，第11圖係顯示將香煙1在狹縫122上予以切斷後的橫剖面。另外，在第11圖中，係省略了成型紙14或外層紙15。狹縫122之底部所形成的形狀，係從橫剖面來觀察，亦可設為與香煙1之外徑或貫通孔121之內徑同心的正圓。因藉由設為與香煙1之外徑或貫通孔121之內徑同心，在使用者扭轉CH濾嘴12時剪斷應力就能均等地施加於CH濾嘴12之剖面，故而變得易於扭轉。另外，如此的狹縫之形狀，係可以依形成狹縫的旋轉刀具之形狀而變更。 Further, the through hole 121 of the CH filter 12 is viewed from a cross section, and may be provided at a position offset from the center. However, the through hole 121 is provided substantially at the center of the CH filter 12, and the user can twist the CH filter 12 more easily. Moreover, the depth of the slit 122 which is a non-penetrating groove over the entire circumference may be fixed or may vary. For example, Fig. 11 is an example of a cross-sectional view taken along the line A-A taken along the line A-A shown in Fig. 3. Specifically, Fig. 11 shows a cross section in which the cigarette 1 is cut on the slit 122. Further, in Fig. 11, the formed paper 14 or the outer layer paper 15 is omitted. The shape formed at the bottom of the slit 122 is a cross-sectional view, and may be a perfect circle concentric with the outer diameter of the cigarette 1 or the inner diameter of the through hole 121. Since it is set to be concentric with the outer diameter of the cigarette 1 or the inner diameter of the through hole 121, the shear stress can be equally applied to the cross section of the CH filter 12 when the user twists the CH filter 12, so that it becomes easy to twist. . Further, the shape of such a slit can be changed depending on the shape of the rotary cutter forming the slit.
又，亦可提供不含上述之煙桿11的濾嘴部 分，且可安裝於任意的煙草製品者。就煙草製品而言，例如可例示具備濾嘴的濾嘴香煙及不具濾嘴之兩切香煙的紙煙、雪茄(cigar)、小雪茄(cigarillo)等。 Moreover, a filter portion not including the above-mentioned tobacco rod 11 can also be provided And can be installed on any tobacco product. The tobacco product may, for example, be a filter cigarette having a filter and a cigarette, a cigar, a cigarillo or the like having two cut cigarettes without a filter.
另外，有關狹縫之深度、或濾嘴之直徑與貫通孔之直徑的比率、醋酸纖維之密度等的規格(spec)、可塑劑之添加量、成型紙或外層紙之材質或基重(basis weight)等，係可適當地選擇較佳的值。例如，為了使貫通孔121閉塞，貫通孔121之內徑較佳是CH濾嘴12之外徑的二分之一以下，更佳為三分之一以下。又，為了容易進行扭轉的操作，狹縫122係以較深者為宜。另一方面，例如為了確保預定的強度，已置入狹縫122的CH濾嘴12之殘留厚度較佳為1mm以上。再者，CH濾嘴亦可使用不用原料紙的無包覆式濾嘴(non wrap filter)，又，與CH濾嘴一起用成型紙來包覆外周的濾嘴，除了醋酸纖維濾嘴以外，亦可適當地組合木炭濾嘴(charcoal filter)、纖維束(tow)埋置型膠囊濾嘴等的已知濾嘴。 In addition, the depth of the slit, the ratio of the diameter of the filter to the diameter of the through hole, the specification of the density of the acetate fiber, the amount of the plasticizer added, the material or basis weight of the molded paper or the outer paper (basis Weight, etc., a preferred value can be appropriately selected. For example, in order to close the through hole 121, the inner diameter of the through hole 121 is preferably one-half or less, more preferably one-third or less, of the outer diameter of the CH filter 12. Further, in order to facilitate the twisting operation, the slit 122 is preferably deep. On the other hand, for example, in order to secure a predetermined strength, the residual thickness of the CH filter 12 that has been placed in the slit 122 is preferably 1 mm or more. Furthermore, the CH filter can also use a non wrap filter that does not use raw paper, and, together with the CH filter, use a molding paper to coat the outer peripheral filter, except for the cellulose acetate filter. A known filter such as a charcoal filter or a tow embedded capsule filter may be appropriately combined.
