Abstract
Description
本發明係有關於特別用於香煙之煙草煙霧濾嘴。 The present invention relates to tobacco smoke filters that are particularly useful in cigarettes.
綜合性能高級(Combined Performance Superior,CPS)煙草煙霧濾嘴係眾所周知的。這些濾嘴包括一個濾芯及兩個包裝材料(一個內包裝材料及一個外包裝材料)。內包裝材料經過壓紋處理，藉以在其一部分長度上開槽或成波紋狀。這導致通道的產生。每個濾嘴將包括一段有槽內包裝材料(「凹槽(flute)」)及一段無槽內包裝材料(「條狀物(bar)」)。這些濾嘴具有提供增加的過濾效率及允許使用較低壓降以實現相同過濾效率的優點。此外，壓紋內包裝材料可以提供可用以作為防偽手段之特殊的最終外觀。 The Combined Performance Superior (CPS) tobacco smoke filter is well known. These filters include a filter element and two packaging materials (one inner packaging material and one outer packaging material). The inner packaging material is embossed so as to be grooved or corrugated over a portion of its length. This leads to the creation of a channel. Each filter will include a slotted inner wrapper ("flute") and a non-grooved inner wrapper ("bar"). These filters have the advantage of providing increased filtration efficiency and allowing the use of lower pressure drops to achieve the same filtration efficiency. In addition, the embossed inner packaging material can provide a special final appearance that can be used as an anti-counterfeiting means.
含有添加劑釋放容器(例如，易碎膠囊)之煙草煙霧濾嘴亦是眾所周知的。添加劑可以是香味劑。吸煙者對濾嘴施加壓力，以使膠囊破裂，從而導致香味劑的釋放。 Tobacco smoke filters containing additive release containers (e.g., frangible capsules) are also well known. The additive can be a fragrance. The smoker applies pressure to the filter to rupture the capsule, resulting in the release of the fragrance.
非常希望將膠囊包含在CPS濾嘴中，以提供 增強的過濾性能，同時亦允許根據要求向使用者輸送香味。目前將CPS濾嘴與膠囊組合的方法需要個別生產CPS濾嘴元件及包含膠囊的濾嘴元件；將這些濾嘴元件連結，以產生雙段濾嘴(例如，具有共同的外包裝材料)。這樣的濾嘴缺少單一的煙草煙霧濾材芯。此方法不允許提供與CPS濾嘴的凹槽部分互相對準的膠囊。 It is highly desirable to include the capsule in the CPS filter to provide Enhanced filtration performance while also allowing the fragrance to be delivered to the user upon request. The current method of combining a CPS filter with a capsule requires separate production of a CPS filter element and a filter element comprising a capsule; these filter elements are joined to create a two-stage filter (eg, having a common outer packaging material). Such filters lack a single tobacco smoke filter core. This method does not allow for the provision of a capsule that is aligned with the groove portion of the CPS filter.
像雙段濾嘴的多段濾嘴由兩段或更多段的濾材所形成。單段濾嘴由單一段的濾材所形成。多段濾嘴(例如，雙段濾嘴)具有比單段濾嘴還高的生產成本，因為需要藉由個別程序來製造不同段的濾材，接著正確地排列及鄰接不同段，以形成多段濾嘴桿。 A multi-stage filter like a two-stage filter is formed by two or more sections of filter media. The single section filter is formed from a single section of filter media. Multi-stage filters (eg, two-stage filters) have higher production costs than single-stage filters because of the need to fabricate different sections of filter media by individual procedures, followed by correctly aligning and adjoining the different sections to form a multi-section filter Rod.
因此，需要一種濾嘴，其將CPS濾嘴的特徵與膠囊組合在單一元件濾嘴中，亦即，一種包括單一濾材芯的濾嘴。這樣的濾嘴可允許單程生產程序及提高的生產效率。 Accordingly, there is a need for a filter that combines the features of a CPS filter with a capsule in a single component filter, that is, a filter that includes a single filter core. Such filters allow for single pass production procedures and increased production efficiency.
依據本發明，提供一種(例如，單段)煙草煙霧濾嘴或濾嘴元件，其包括煙草煙霧濾材製的一縱向延伸(例如，大致圓柱形)芯；一第一(例如，至少部分波紋狀的，例如，透氣的)包裝材料，其圍繞該芯；以及一第二包裝材料，其圍繞該第一包裝材料，該第一包裝材料至少與該第二包裝材料一起(例如，在其本身與該第二包裝材料之間)界定該濾嘴或濾嘴元件的至少一個縱向延伸(例如，周邊)通道，其中該(或每個)縱向延伸通道延伸小於該濾嘴或濾嘴元件的整個長度，使得該濾嘴或濾嘴 元件的一縱向延伸部分沒有縱向延伸通道；該濾嘴或濾嘴元件進一步包括至少一個添加劑釋放容器(例如，膠囊，例如，易碎膠囊)。 According to the present invention there is provided a (eg, single-stage) tobacco smoke filter or filter element comprising a longitudinally extending (eg, generally cylindrical) core of tobacco smoke filter material; a first (eg, at least partially corrugated) a, for example, a breathable packaging material surrounding the core; and a second packaging material surrounding the first packaging material, the first packaging material being at least with the second packaging material (eg, in its own Between the second packaging materials, at least one longitudinally extending (eg, peripheral) channel defining the filter or filter element, wherein the (or each) longitudinally extending channel extends less than the entire length of the filter or filter element To make the filter or filter A longitudinally extending portion of the element has no longitudinally extending passage; the filter or filter element further includes at least one additive release container (eg, a capsule, such as a frangible capsule).
煙草煙霧濾材製的該縱向延伸(例如，大致圓柱形)芯係煙草煙霧濾材製的單一芯。換句話說，該芯由一段濾材所形成，而不是由例如彼此緊靠的個別段所形成。申請人已經發現，一種包括煙草煙霧濾材製的單一芯之濾嘴或濾嘴元件可以藉由單程生產程序來更有效率地生產。再者，可以將該添加劑釋放容器定位在一個指定位置，以允許根據要求向吸煙者輸送香味。例如，可以將一個添加劑釋放容器定位成與沒有通道之該濾嘴或濾嘴元件的區段互相對準，這可以對吸煙者提供增強的香味釋放(或增強的吸煙感覺)。本發明的濾嘴或濾嘴元件可以作為單段併入多段濾嘴中。這可允許增加可以併入該多段濾嘴中之特徵的數量。例如，本發明的濾嘴元件可以與一含有微粒添加劑(例如，活性碳顆粒)的濾嘴元件連結，以允許增強的過濾及根據需求向使用者輸送香味。該項技藝所已知的現有方法包括將香料(例如，薄荷腦)噴灑至含碳的煙草煙霧濾材上。這不允許香料根據需求來釋放與碳的增強過濾性質相結合。該項技藝所已知的現有方法亦未能將添加劑釋放容器及碳過濾與允許進一步增強過濾的周邊縱向延伸通道結合。 The longitudinally extending (e.g., generally cylindrical) core of the tobacco smoke filter material is a single core made of tobacco smoke filter material. In other words, the core is formed from a length of filter material rather than being formed, for example, by individual segments that abut each other. Applicants have discovered that a single core filter or filter element comprising a tobacco smoke filter material can be produced more efficiently by a single pass production procedure. Again, the additive release container can be positioned at a designated location to allow the fragrance to be delivered to the smoker as desired. For example, an additive release container can be positioned to align with a section of the filter or filter element without a channel, which can provide an enhanced flavor release (or enhanced smoking sensation) to the smoker. The filter or filter element of the present invention can be incorporated into a multi-segment filter as a single stage. This may allow an increase in the number of features that can be incorporated into the multi-segment filter. For example, the filter element of the present invention can be coupled to a filter element containing particulate additives (e.g., activated carbon particles) to allow for enhanced filtration and delivery of fragrance to the user as desired. Existing methods known in the art include spraying a fragrance (e.g., menthol) onto a carbonaceous tobacco smoke filter. This does not allow the fragrance to be released upon demand in combination with the enhanced filtration properties of carbon. Existing methods known in the art have also failed to combine additive release vessels and carbon filtration with peripheral longitudinally extending channels that allow for further enhanced filtration.
較佳地，該第一包裝材料至少與該第二包裝材料一起(例如，在其本身與該第二包裝材料之間)界定該濾嘴或濾嘴元件的至少一個縱向延伸(例如，周邊)通 道，其中該(或每個)縱向延伸通道延伸小於該濾嘴或濾嘴元件的整個長度，使得該濾嘴或濾嘴元件的一縱向延伸部分沒有縱向延伸通道。較佳地，可以有5個或更多個縱向延伸通道，例如，5至25個縱向延伸通道，例如，9至20個縱向延伸通道。周長約20-25mm的濾嘴或濾嘴元件可以包括例如14至20個縱向延伸通道。周長約為16-17mm的濾嘴或濾嘴元件可以包括例如9至14個縱向延伸通道。 Preferably, the first packaging material defines at least one longitudinal extension (eg, perimeter) of the filter or filter element with at least the second packaging material (eg, between itself and the second packaging material) through The track wherein the (or each) longitudinally extending channel extends less than the entire length of the filter or filter element such that a longitudinally extending portion of the filter or filter element has no longitudinally extending passage. Preferably, there may be 5 or more longitudinally extending channels, for example 5 to 25 longitudinally extending channels, for example, 9 to 20 longitudinally extending channels. A filter or filter element having a circumference of about 20-25 mm may comprise, for example, 14 to 20 longitudinally extending channels. A filter or filter element having a circumference of about 16-17 mm may comprise, for example, 9 to 14 longitudinally extending channels.
較佳地，該第一包裝材料係紙質包裝材料。較佳地，該第一包裝材料係透氣性包裝材料。該第一包裝材料可以是例如透氣性濾紙(例如，波紋狀透氣性濾紙)或醋酸纖維素包裝材料(例如，波紋狀透氣性醋酸纖維素)。該內包裝材料的重量可以是50公克/平方公尺至100公克/平方公尺，例如，80公克/平方公尺。 Preferably, the first packaging material is a paper packaging material. Preferably, the first packaging material is a breathable packaging material. The first packaging material may be, for example, a gas permeable filter paper (for example, corrugated gas permeable filter paper) or a cellulose acetate packaging material (for example, corrugated gas permeable cellulose acetate). The inner packaging material may weigh from 50 grams per square meter to 100 grams per square meter, for example, 80 grams per square meter.
較佳地，該第一(例如，透氣的)包裝材料具有縱向延伸的波紋，該等波紋至少與該第二包裝材料一起(例如，在其本身與該第二包裝材料之間)界定該等縱向延伸通道。該第一包裝材料可以是(例如，至少部分)波紋狀的，該等波紋[例如，與該第二包裝材料一起]提供(界定)5個或更多個縱向延伸通道，例如，5至25個縱向延伸通道，例如，9至20個縱向延伸通道。周長約20-25mm的濾嘴或濾嘴元件可以包括例如14至20個縱向延伸通道(由該等波紋來提供)。周長約為15-17mm的濾嘴或濾嘴元件可以包括例如9至14個縱向延伸通道(由該等波紋來提供)。在此，術語波紋狀包括成形為摺 疊的含義，其包括平行且交替的脊部及溝槽。相較於具有相同壓降的傳統單醋酸酯濾嘴相比，將通道併入濾嘴或濾嘴元件中允許改善的過濾性能(例如，改善的焦油滯留)。 Preferably, the first (eg, gas permeable) packaging material has longitudinally extending corrugations that define at least the second packaging material (eg, between itself and the second packaging material) Longitudinal extension channel. The first wrapper may be (eg, at least partially) corrugated, such as with the second wrapper, providing (defining) five or more longitudinally extending channels, for example, 5 to 25 Longitudinal extension channels, for example, 9 to 20 longitudinally extending channels. A filter or filter element having a circumference of about 20-25 mm may comprise, for example, 14 to 20 longitudinally extending channels (provided by the corrugations). A filter or filter element having a circumference of about 15-17 mm may comprise, for example, 9 to 14 longitudinally extending channels (provided by the corrugations). Here, the term corrugated includes forming into a fold The meaning of a stack, which includes parallel and alternating ridges and grooves. Incorporating a channel into a filter or filter element allows for improved filtration performance (e.g., improved tar retention) compared to conventional monoacetate filters having the same pressure drop.
本發明的濾嘴或濾嘴元件可具有10mm至30mm的周長，例如，16mm的超細濾嘴或濾嘴元件。 The filter or filter element of the present invention may have a circumference of from 10 mm to 30 mm, for example, a 16 mm ultrafine filter or filter element.
包括縱向延伸通道(例如，圍繞該濾嘴的周圍)(例如，其包括波紋)之該濾嘴的該(或每個)部分在此稱為凹槽或凹槽部分。不包括縱向延伸通道(例如，圍繞該濾嘴的周圍)之該濾嘴的該(或每個)部分在此稱為條狀物或條狀部分。 The (or each) portion of the filter that includes the longitudinally extending channel (eg, surrounding the filter) (eg, including the corrugations) is referred to herein as a groove or groove portion. The (or each) portion of the filter that does not include the longitudinally extending passage (e.g., around the perimeter of the filter) is referred to herein as a strip or strip portion.
較佳地，該濾嘴或濾嘴元件包括從該濾嘴或濾嘴元件的第一端縱向延伸之至少一個通道，其中該濾嘴或濾嘴元件的第二端沒有縱向延伸通道。此實例可以包括在該濾嘴的一端之一凹槽部分及在該濾嘴的另一端之一條狀部分。這種配置可以提供更理想的最終外觀。在使用者可見的一端定位凹槽部分允許產品之間的視覺區分，例如，不包含添加劑釋放容器的產品與包含添加劑釋放容器的產品之間的視覺區別。 Preferably, the filter or filter element includes at least one passage extending longitudinally from the first end of the filter or filter element, wherein the second end of the filter or filter element has no longitudinally extending passage. This example may include a groove portion at one end of the filter and a strip portion at the other end of the filter. This configuration provides a more desirable final look. Positioning the groove portion at the end visible to the user allows for a visual distinction between products, for example, a visual distinction between a product that does not contain an additive release container and a product that contains an additive release container.
在另一個實例中，該波紋狀第一包裝材料可以是著色的(例如，綠色)，以提供進一步的視覺區分。該第一包裝材料可以包含顏料。較佳地，該第一包裝材料包含顏料，該顏料提供與該煙草煙霧濾材及/或該第二包裝材料的顏色成明顯對比的顏色。該包裝材料的顏色可以用於識別由該添加劑釋放容器所提供的香味。著色 的第一包裝材料亦可用以作為防偽手段。 In another example, the corrugated first wrapper material can be colored (eg, green) to provide a further visual distinction. The first packaging material can comprise a pigment. Preferably, the first packaging material comprises a pigment that provides a color that is significantly contrasted with the color of the tobacco smoke filter and/or the second packaging material. The color of the packaging material can be used to identify the aroma provided by the additive release container. Coloring The first packaging material can also be used as a security measure.
在另一個實例中，該濾嘴或濾嘴元件包括從該濾嘴或濾嘴元件的上游端縱向延伸之至少一個通道及從該濾嘴或濾嘴元件的下游端縱向延伸之至少一個通道以及沒有縱向延伸通道之該濾嘴或濾嘴元件的一中央部分。此實例可以包括在每一個端處的一凹槽部分及單一中央條狀部分。 In another example, the filter or filter element includes at least one passage extending longitudinally from an upstream end of the filter or filter element and at least one passage extending longitudinally from a downstream end of the filter or filter element and There is no central portion of the filter or filter element that extends longitudinally. This example may include a groove portion at each end and a single central strip portion.
在另一個實例中，該濾嘴或濾嘴元件包括該濾嘴或濾嘴元件的至少一個縱向延伸通道，該至少一個縱向延伸通道只延伸該濾嘴或濾嘴元件的長度之一部分，並且位於該濾嘴或濾嘴元件的中央部分，使得該(或一)縱向延伸通道沒有從該濾嘴或濾嘴元件的上游或下游端延伸。此實例可以包括在每一個端處的一條狀部分及單一中央凹槽部分。這將提供與縱向通道的存在相關之增強的過濾性能，但不會影響最終外觀。 In another example, the filter or filter element includes at least one longitudinally extending passage of the filter or filter element, the at least one longitudinally extending passage extending only a portion of the length of the filter or filter element and located The central portion of the filter or filter element is such that the (or a) longitudinally extending passage does not extend from the upstream or downstream end of the filter or filter element. This example may include a strip portion at each end and a single central groove portion. This will provide enhanced filtering performance associated with the presence of longitudinal channels, but will not affect the final appearance.
較佳地，每個縱向延伸通道的長度為2mm或更大，較佳地，在2.5mm至23mm之間，更佳地，在3mm至15mm之間，更佳地，在3.5mm至9mm之間。如果該濾嘴在兩端皆具有凹槽，則從一端(上游或下游)延伸的縱向延伸通道可以具有與從另一端延伸的那些縱向延伸通道不同的長度，或者它們可以具有相同的長度。在該濾嘴的兩端處之縱向延伸通道的長度可以在7至8mm之間。在該濾嘴的兩端處之縱向延伸通道的長度可以在3至4mm長之間，例如，3.75mm長。提供這些尺寸的縱向延伸通道意味著該濾嘴的性能(焦油滯留等)應該是可 接受的，並且可以額外地確保獲得本發明的優點(例如，一致的壓降、增強的滯留作用)。 Preferably, each of the longitudinally extending passages has a length of 2 mm or more, preferably between 2.5 mm and 23 mm, more preferably between 3 mm and 15 mm, and even more preferably between 3.5 mm and 9 mm. between. If the filter has grooves at both ends, the longitudinally extending passages extending from one end (upstream or downstream) may have different lengths than those extending from the other end, or they may have the same length. The length of the longitudinally extending channels at the ends of the filter may be between 7 and 8 mm. The length of the longitudinally extending passage at the ends of the filter may be between 3 and 4 mm long, for example, 3.75 mm long. Providing longitudinal extension channels of these dimensions means that the performance of the filter (tar retention, etc.) should be Accepted and additionally ensured the advantages of the invention (e.g., consistent pressure drop, enhanced retention).
較佳地，該濾嘴或濾嘴元件包括只有一個添加劑釋放容器(亦即，該濾嘴或濾嘴元件較佳地包括單一添加劑釋放容器，而不是兩個或更多個添加劑釋放容器)。該濾嘴或濾嘴元件包括兩個或更多個添加劑釋放容器。 Preferably, the filter or filter element comprises only one additive release container (i.e., the filter or filter element preferably comprises a single additive release container instead of two or more additive release containers). The filter or filter element comprises two or more additive release containers.
在一個實例中，該濾嘴或濾嘴元件包括至少一個添加劑釋放容器，該至少一個添加劑釋放容器與沒有縱向延伸通道之該濾嘴或濾嘴元件的該(或一)縱向延伸部分互相對準。較佳地，該濾嘴或濾嘴元件包括只有一個添加劑釋放容器(亦即，該濾嘴或濾嘴元件較佳地包括單一添加劑釋放容器，而不是兩個或更多個添加劑釋放容器)。較佳地，該濾嘴或濾嘴元件包括只有一個添加劑釋放容器，其中該添加劑釋放容器與沒有縱向延伸通道之該濾嘴或濾嘴元件的該(或一)縱向延伸部分互相對準。此實例可以包括一種濾嘴或濾嘴元件，其包括在一端的一凹槽部分及在另一端的一條狀部分，其中具有一添加劑釋放容器與該條狀部分對準。申請人已出乎意外地發現，相較於一添加劑釋放容器與該凹槽部分對準的定位，該添加劑釋放容器與該條狀部分對準的定位對使用者提供更高的香料產量。該添加劑釋放容器在該條狀部分中的定位可以用於提供使用者較高量的香料。再者，該煙草煙霧濾材可以含有一添加劑，例如，香料。這可以提供使用者香料的初始產量。可以使用一添加劑 釋放容器來增加香料的產量，以允許使用者改變吸煙體驗，例如，在吸煙期間提供增強的香味。可以使用一第二添加劑釋放容器來進一步增加香料的產量，以再次允許使用者改變吸煙體驗，例如，提供進一步增強的香味。該濾料及該(等)添加劑釋放容器中所使用的香料可以全部是相同的香料，或者它們可以是不同的香料(例如，互補香料)。 In one example, the filter or filter element includes at least one additive release container that is aligned with the (or a) longitudinally extending portion of the filter or filter element without a longitudinally extending passageway . Preferably, the filter or filter element comprises only one additive release container (i.e., the filter or filter element preferably comprises a single additive release container instead of two or more additive release containers). Preferably, the filter or filter element comprises only one additive release container, wherein the additive release container is aligned with the (or a) longitudinally extending portion of the filter or filter element without a longitudinally extending passage. This example can include a filter or filter element that includes a groove portion at one end and a strip portion at the other end with an additive release container aligned with the strip portion. Applicants have unexpectedly discovered that the positioning of the additive release container in alignment with the strip portion provides a higher perfume yield to the user than the positioning of the additive release container in alignment with the groove portion. The positioning of the additive release container in the strip portion can be used to provide a higher amount of flavor to the user. Further, the tobacco smoke filter material may contain an additive such as a fragrance. This can provide an initial yield of the user's fragrance. Can use an additive The container is released to increase the yield of the fragrance to allow the user to change the smoking experience, for example, to provide an enhanced fragrance during smoking. A second additive release container can be used to further increase the yield of the fragrance to again allow the user to change the smoking experience, for example, to provide a further enhanced fragrance. The filter material and the perfume used in the (etc.) additive release container may all be the same perfume, or they may be different perfumes (e.g., complementary fragrances).

Surrounding the core 2 is a first packaging material 3 made of a gas permeable filter paper (basis weight 80 gsm) which has been embossed to provide corrugations along a portion of its length. A second packaging material 4 made of a corrugated gas permeable filter paper (27 gsm basis weight) was wrapped around the first packaging material 3. The first wrapping material 3 is embossed to provide corrugation over about half of its length such that it is corrugated toward one end 1a of the filter 1 and smoothed at the second end 1b of the filter 1. The corrugated portion of the first wrapper 3 facing the end 1a defines between its own and the non-corrugated second wrapper 4 24 channels 5a extending longitudinally around the filter of the core (ie, the peripheral channel) ). The surface of the tobacco filter 2 and the first packaging material 3 The ripples are consistent. The corrugated first wrapper 3 forms corrugations only over a portion of its length such that the longitudinally extending channel 5a extends less than the entire length of the filter such that the longitudinally extending portion 6 of the filter 1 has no longitudinally extending channels. The filter also contains a frangible capsule 9, which contains a menthol flavoring agent. The capsule 9 is completely enclosed within the core 2 of the tobacco smoke filter material and is invisible, but the approximate position aligned with the portion 6 of the filter (without the passage) is indicated by dashed lines.
濾嘴之包含圍繞濾嘴的周圍之縱向延伸通道5a的部分7可以稱為凹槽或凹槽部分。濾嘴的不包含圍繞濾嘴的周圍之縱向延伸通道的部分6可以稱為條狀物或條狀部分。 The portion 7 of the filter that includes the longitudinally extending passage 5a around the periphery of the filter may be referred to as a groove or groove portion. The portion 6 of the filter that does not include a longitudinally extending passage around the periphery of the filter may be referred to as a strip or strip portion.
第3圖說明在沿著濾嘴的縱軸線切割時第1圖之示意剖面圖。可以看出，膠囊9與濾嘴的部分6對準，所述部分不包含縱向延伸的周邊通道5a。 Figure 3 illustrates a schematic cross-sectional view of Figure 1 as it is cut along the longitudinal axis of the filter. It can be seen that the capsule 9 is aligned with the portion 6 of the filter which does not comprise a longitudinally extending peripheral channel 5a.
將理解的是，濾嘴1可以藉由該項技藝所已知的方法連結至包裹的煙草桿上，以形成香煙。濾嘴可以例如藉由環形接裝紙(ring tipping)連結至包裹的煙草桿上(環形接裝紙僅圍繞(包裹的)濾嘴與煙草桿的相鄰端部來接合，以暴露大部分的濾嘴包裝材料)。濾嘴可以例如藉由完全接裝外包裝材料(full tipping overwrap)(其圍繞整個濾嘴長度及煙草桿的相鄰端部來接合)來連結。如果濾嘴1的條狀部分連結至煙草桿，則濾嘴的凹槽部分在香煙的煙嘴端處是可看見的。這可以用以作為防偽手段。第一包裝材料3可以是著色的(亦即，可以包含顏料)。例如，第一包裝材料3可以著綠色的，以便與煙草煙霧濾材的顏色(其通常是白色)形成對 比。這種顏色可進一步進行用於防偽目的之濾嘴鑑別，並且可用於識別香味。如果濾嘴1的凹槽部分連結至煙草桿，則濾嘴1的條狀部分將位於香煙的煙嘴端處。這提供一般的香煙外觀，但是具有與存在的通道相關之增強過濾性能。 It will be appreciated that the filter 1 can be attached to the wrapped tobacco rod by methods known in the art to form a cigarette. The filter can be attached to the wrapped tobacco rod, for example by ring tipping (the annular tipping paper is only joined around the (wrapped) filter and the adjacent end of the tobacco rod to expose most of the Filter packaging material). The filter can be joined, for example, by a full tipping overwrap that engages around the length of the entire filter and the adjacent ends of the tobacco rod. If the strip portion of the filter 1 is joined to the tobacco rod, the groove portion of the filter is visible at the mouth end of the cigarette. This can be used as a means of anti-counterfeiting. The first packaging material 3 can be colored (ie, can contain pigments). For example, the first wrapper 3 may be green to form a pair with the color of the tobacco smoke filter, which is typically white. ratio. This color can be further used for filter identification for anti-counterfeiting purposes and can be used to identify fragrance. If the groove portion of the filter 1 is joined to the tobacco rod, the strip portion of the filter 1 will be located at the mouth end of the cigarette. This provides a general cigarette appearance but with enhanced filtration performance associated with the existing channels.
在第2圖中，濾嘴101包括醋酸纖維素絲束的形式之煙草煙霧濾材製的縱向延伸圓柱形芯102(長絲丹尼為3.0，總丹尼為30,000)。圍繞芯102的是透氣性濾嘴紙(基重80gsm)製的第一包裝材料103，第一包裝材料103已經過壓紋，以沿著其長度的一部分提供波紋。將不波紋狀透氣性濾嘴紙(27gsm基重)製的第二包裝材料104包裹在第一包裝材料103周圍。第一包裝材料103經過壓紋，以在其長度的大約一半上提供波紋，使得其朝向濾嘴101的一端101a成波紋狀，而在濾嘴101的第二端101b處成平滑。第一包裝材料103之朝向端部101a的波紋狀部分在其本身與不波紋狀第二包裝材料104之間界定圍繞芯的周圍之濾嘴的縱向延伸之24個通道105a(亦即，周邊通道)。煙草濾芯102的表面與第一包裝材料103中的波紋一致。波紋狀的第一包裝材料103僅在其長度的一部分上形成波紋，使得縱向延伸的通道105a延伸小於濾嘴的整個長度，以致於濾嘴101的縱向延伸部分106沒有縱向延伸的通道(而濾嘴的縱向延伸部分107包含縱向延伸通道105a)。濾嘴亦包含易碎的膠囊109，膠囊109包含薄荷腦香味劑。膠囊109完全被包圍 在煙草煙霧濾材製的芯102內且是不可看見的，但是以虛線來表示與濾嘴的部分107(其包含縱向延伸通道105a)對準的近似位置。 In Fig. 2, the filter 101 comprises a longitudinally extending cylindrical core 102 of tobacco smoke filter material in the form of a cellulose acetate tow (3.0 for denier Danny and 30,000 for total denier). Surrounding the core 102 is a first packaging material 103 made of a gas permeable filter paper (basis weight 80 gsm) that has been embossed to provide corrugations along a portion of its length. A second packaging material 104 made of a corrugated gas permeable filter paper (27 gsm basis weight) is wrapped around the first packaging material 103. The first wrapper 103 is embossed to provide corrugation over about half of its length such that it is corrugated toward one end 101a of the filter 101 and smoothed at the second end 101b of the filter 101. The corrugated portion of the first wrapper 103 facing the end 101a defines, between itself and the non-corrugated second wrapper 104, 24 channels 105a extending longitudinally around the filter around the core (ie, the peripheral channel) ). The surface of the tobacco filter cartridge 102 conforms to the corrugations in the first packaging material 103. The corrugated first wrapper 103 forms corrugations only over a portion of its length such that the longitudinally extending channel 105a extends less than the entire length of the filter such that the longitudinally extending portion 106 of the filter 101 has no longitudinally extending channels (and The longitudinally extending portion 107 of the mouth includes a longitudinally extending channel 105a). The filter also contains a frangible capsule 109 containing a menthol flavoring agent. Capsule 109 is completely surrounded Within the core 102 of the tobacco smoke filter material, it is invisible, but the approximate position aligned with the portion 107 of the filter (which includes the longitudinally extending passage 105a) is indicated by dashed lines.
濾嘴之包含圍繞濾嘴的周圍之縱向延伸通道105a的部分107可以稱為凹槽或凹槽部分。濾嘴的不包含圍繞濾嘴的周圍之縱向延伸通道的部分106可以稱為條狀物或條狀部分。 The portion 107 of the filter that includes the longitudinally extending passage 105a around the periphery of the filter may be referred to as a groove or groove portion. The portion 106 of the filter that does not include a longitudinally extending passage around the periphery of the filter may be referred to as a strip or strip portion.
將理解的是，濾嘴101可以藉由該項技藝所已知的方法連結至包裹的煙草桿上，以形成香煙。濾嘴可以例如藉由環形接裝紙連結至包裹的煙草桿上(環形接裝紙僅圍繞(包裹的)濾嘴與煙草桿的相鄰端部來接合，以暴露大部分的濾嘴包裝材料)。濾嘴可以例如藉由全接裝外包裝材料(其圍繞整個濾嘴長度與煙草桿的相鄰端部來接合)來連結。如果濾嘴101的條狀部分連結至煙草桿，則濾嘴的凹槽部分在香煙的煙嘴端處是可看見的。這可以用以作為防偽手段。第一包裝材料103可以是著色的(亦即，可以包含顏料)。例如，第一包裝材料103可以著綠色的，以便與煙草煙霧濾材的顏色(其通常是白色)形成對比。這種顏色可進一步進行用於防偽目的之濾嘴鑑別，並且可用於識別香味。如果濾嘴101的凹槽部分連結至煙草桿，則濾嘴101的條狀部分將位於香煙的煙嘴端處。這提供一般的香煙外觀，但是具有與存在的通道相關之增強過濾性能。 It will be appreciated that the filter 101 can be attached to the wrapped tobacco rod by methods known in the art to form a cigarette. The filter can be attached to the wrapped tobacco rod, for example by an endless tipping paper (the annular tipping paper is only joined around the (wrapped) filter and the adjacent end of the tobacco rod to expose most of the filter packaging material ). The filter can be joined, for example, by a fully-engaged overwrap material that engages the entire end of the tobacco rod and the adjacent ends of the tobacco rod. If the strip portion of the filter 101 is joined to the tobacco rod, the groove portion of the filter is visible at the mouth end of the cigarette. This can be used as a means of anti-counterfeiting. The first packaging material 103 can be colored (ie, can contain pigments). For example, the first wrapper 103 can be green to contrast with the color of the tobacco smoke filter, which is typically white. This color can be further used for filter identification for anti-counterfeiting purposes and can be used to identify fragrance. If the groove portion of the filter 101 is joined to the tobacco rod, the strip portion of the filter 101 will be located at the mouth end of the cigarette. This provides a general cigarette appearance but with enhanced filtration performance associated with the existing channels.
依據本發明的濾嘴或濾嘴元件(例如，第1及 2圖)可以以下列方式來生產。方法及機器在該項技藝中係眾所周知的。使用改進的單醋酸酯濾嘴機器(mono acetate filter machine)(該項技藝已知)來生產濾嘴。機器需要該項技藝所已知的CPS套件及膠囊***器套件。濾嘴藉由生產多倍長度桿來生產。機器絲束處理設定成形成縱向延伸的單一醋酸纖維素絲束桿。機器接著設定成饋入透氣性濾嘴紙且在透氣性濾嘴紙上進行壓紋，導致濾嘴上之凹槽(壓紋、波紋狀)部分與條狀部分對準。然後，膠囊***器套件設定成在限定的位置將膠囊***醋酸纖維素絲束中。藉由對膠囊***器套件使用不同的變化部位，可以將膠囊***條狀部分、凹槽部分或條狀部分與凹槽部分的連接處。亦可以生產含有兩個膠囊的濾嘴。切割連續桿以形成個別濾嘴的步驟(或多個步驟)配置成使得切割端構成濾嘴的上游端及濾嘴的下游端。所述方法允許濾嘴的特徵可根據需要來客製化，例如，改變膠囊位置、凹槽方位及濾嘴包裝材料的顏色皆可輕易改變。 Filter or filter element according to the invention (for example, 1st and 2) can be produced in the following manner. Methods and machines are well known in the art. The filter is produced using a modified mono acetate filter machine (known in the art). The machine requires a CPS kit and capsule inserter kit known in the art. The filter is produced by producing multiple length rods. The machine tow treatment is set to form a longitudinally extending single cellulose acetate tow bar. The machine is then set to feed the gas permeable filter paper and emboss on the gas permeable filter paper, causing the grooves (embossed, corrugated) portions of the filter to align with the strip portions. The capsule inserter kit is then set to insert the capsule into the cellulose acetate tow at a defined location. By using different variations of the capsule inserter kit, the capsule can be inserted into the strip portion, the groove portion or the junction of the strip portion and the groove portion. It is also possible to produce a filter containing two capsules. The step (or steps) of cutting the continuous rod to form individual filters is configured such that the cutting end constitutes the upstream end of the filter and the downstream end of the filter. The method allows the characteristics of the filter to be customized as desired, for example, changing the position of the capsule, the orientation of the groove, and the color of the filter wrapper can be easily changed.
進行一個實驗，以測量膠囊位置對香煙使用者所獲得的薄荷腦產量的影響。測試四個濾嘴實施例A至D。藉由實例3的方法來製備濾嘴。所有測試的濾嘴包括一端的條狀部分、另一端的凹槽部分及至少一個含有薄荷腦添加劑的膠囊。設想濾嘴的凹槽末端係與使用者的口腔對準之末端。因此，從凹槽末端測量薄荷腦產量。濾嘴A係依據第1圖的濾嘴且在不壓碎單一膠囊的 情況下進行測試。濾嘴B係依據第1圖的濾嘴，其包括與條狀部分對準的單一膠囊，此單一膠囊在測試之前被壓碎，以釋放薄荷腦添加劑。濾嘴B的剖面圖顯示於第4圖中。濾嘴C係依據第3圖的濾嘴，其包括與凹槽部分對準的單一膠囊，此單一膠囊在測試之前被壓碎。濾嘴C的剖面圖已顯示於第4圖中。濾嘴D包括與條狀部分對準的單一膠囊及與凹槽部分對準的單一膠囊。在測試之前將兩個膠囊壓碎。濾嘴D的剖面圖已顯示於第4圖中。 An experiment was conducted to measure the effect of capsule position on the menthol production obtained by cigarette users. Four filter examples A through D were tested. The filter was prepared by the method of Example 3. All tested filters included a strip portion at one end, a groove portion at the other end, and at least one capsule containing a menthol additive. It is envisaged that the end of the groove of the filter is aligned with the end of the user's mouth. Therefore, menthol production was measured from the end of the groove. Filter A is based on the filter of Figure 1 and does not crush a single capsule Test in case. Filter B is a filter according to Figure 1 comprising a single capsule aligned with the strip portion which is crushed prior to testing to release the menthol additive. A cross-sectional view of the filter B is shown in Fig. 4. Filter C is a filter according to Figure 3 which includes a single capsule aligned with the groove portion which is crushed prior to testing. A cross-sectional view of filter C is shown in Figure 4. The filter D includes a single capsule aligned with the strip portion and a single capsule aligned with the groove portion. The two capsules were crushed prior to testing. A cross-sectional view of the filter D is shown in Fig. 4.
藉由該項技藝所熟知的方法測量每個濾嘴的薄荷腦滯留數據。對於每個濾嘴實施例，重複測量四次。結果已在表1至4中說明。墊測量數據(pad measurement data)表示煙霧中薄荷腦的產量。濾嘴的平均薄荷腦煙霧產量已總結在表1至4中。 The menthol retention data for each filter was measured by methods well known in the art. For each filter embodiment, the measurement was repeated four times. The results are illustrated in Tables 1 to 4. Pad measurement data indicates the production of menthol in the smoke. The average menthol smoke yield of the filter has been summarized in Tables 1 to 4.
申請人已經發現，當壓碎的膠囊與條狀部分對準時，煙霧中的薄荷腦產量較高。不希望受理論約束，認為凹槽允許煙霧繞道至煙嘴端，因此在醋酸纖維素濾材中保留較少的薄荷腦。申請人已進一步發現，壓碎在條狀部分中的膠囊及在凹槽部分中的膠囊(濾嘴D)不等於藉由將濾嘴B及C的薄荷腦產量數據加在一起所獲得的產量。獲得的薄荷腦煙霧產量之多樣性表示香味產量可以根據本發明中之膠囊位置而變化。 Applicants have discovered that menthol production in smoke is higher when the crushed capsule is aligned with the strip portion. Without wishing to be bound by theory, it is believed that the grooves allow the smoke to bypass the mouth end and therefore retain less menthol in the cellulose acetate filter. Applicants have further discovered that capsules crushed in the strip portion and capsules in the groove portion (filter D) are not equal to the yield obtained by adding together the menthol yield data of filters B and C. . The diversity of menthol smoke yields obtained indicates that the aroma yield can vary depending on the position of the capsule in the present invention.
