200932129 九、發明說明： 【發明所屬之技術領域】 本揭示一般係有關於一種香煙物品，而且更特別是一 種於卷紙上具有圖案，以在隨便置於基台上時降低香煙物 品之引燃性的香煙物品。 【先前技術】 美國專利US 5 878 754 及US 6 997 190 揭示香煙， 其等之卷紙具有透氣率減少的環形區域，該環形區域減少 點燃之香煙燃燒其等所接觸之材料之傾向。 【發明內容】 香煙物品包括煙支及由具有額定透氣率之底層紙卷形 成之卷紙。較佳地，添加材料區根據包括多個沿煙支縱向 地分隔並沿圓周方向分隔之區域的圖案塗布於底層紙卷。 各區域較佳爲包括至少兩個實質上相對之添加材料區，此 等區呈現較額定透氣率低之透氣率。添加材料區較佳爲具 有充分之大小、形狀及添加材料濃度，而在煙支悶燒且置 於基台上時，煙支有在對應區域處熄滅傾向。對各第一、 第二及第三連續區域，第二區域之區係自第一區域之區沿 圓周方向偏置。此外第三區域之區係自第一及第二區域沿 圓周方向偏置。 較佳地，圖案實質上沿煙支連續，使得在將煙支置於 基台上及自一端觀看時，至少一個區域安置成其添加材料 區實質上位於煙支之側部處。 香煙物品較佳爲呈現不大於約25 %之引燃性，及不大 200932129 於約5 Ο %之自熄値。 依照本揭示之香煙物品較佳爲包括具有由低透氣率膜 形成化合物形成之圖案的卷紙。選擇圖案，使得在香煙物 品置於基台上時’香煙物品在前進燃燒線到達其中膜形成 化合物存在於香煙物品未接觸基台之側面的一或多個縱向 位置時自熄，但是具有膜形成化合物或試劑之側面在吸煙 者持香煙物品時不造成香煙物品自熄。因此圖案可考量通 過香煙物品接觸基台之側面或側部的阻礙氣流而選擇。如 此香煙物品可具有降低之引燃性及令人滿意之自由燃燒品 質。 香煙物品可具有圓形或近圓形橫切面，其意指香煙物 品之任何側面或側部可接基台而安置，如在將香煙物品放 在表面上時或在隨便放置香煙物品時。關於此點，在此所 述之圖案界定不接觸基台之具有膜形成化合物的側面或側 部，不論香煙物品恰在接觸基台時之定向爲何。香煙物品 物品亦可具有非圓形橫切面。 卷紙及其添加材料區可包括多個不連續形狀，其各延 伸不超過煙支之長度。在多個沿煙支之分隔縱向位置處， 僅第一及第二圖案形狀存在於實質上垂直煙支之縱軸而取 之橫切面。在此位置處，第一形狀僅配置於香煙物品之第 一側面上，而且第二形狀僅配置於與香煙物品之第一側面 相對之第二側面上。第一及第二形狀可分開實質上1 80°， 而且具有實質上小於底層紙卷之孔隙性的孔隙性。如果需 要則可排列多個不連續形狀，使得通過煙支之橫切面與至 200932129 少兩個此不連續形狀交叉。 【實施方式】 依照本說明，第一具體實施例之香煙物品20 (參見第 1圖）包括煙支22。煙支22可包括煙草濾嘴且被卷紙24 包圍。香煙物品20之一端可包括合適之濾嘴26，其被合 適之水鬆紙2 7包圍。香煙物品2 0 —般按香煙物品之長度 可具有大致圓形橫切面。儘管如此，包括例如橢圓之其他 橫切面形狀在本說明之範圍內。煙支2 2具有自水鬆紙2 7 之邊緣沿香煙物品20之縱軸A測量至煙支22之自由端的 額定長度L。例如額定長度可爲約60毫米至約1 00毫米之 範圍。 卷紙24包括一般可滲透空氣之底層紙卷。卷紙之透氣 率一般按Coresta單位識別。Coresta單位按每單位壓力差 (即水公分數）每單位面積（即平方公分）之體積流速（ 即立方公分/秒）換算而測量紙透氣率。習知卷紙之底層紙 卷亦具有已知之底層重量，其測得每平方米之克數，簡寫 成” gsm”。業界常用典型香煙物品之底層紙卷的透氣率及底 層重量列於下表： 透氣率，Coresta單位 底層重量，gsm 24 25 33 25 46 25 60 26 爲了本說明之目的，較佳卷紙之底層紙卷24具有至少 200932129 約20 Coresta單位之透氣率。最佳爲卷紙具有大於約3〇 Celesta之透氣率’如額定透氣率爲約33及約a coresta 且底層重量爲約25 gsm之常用底層紙卷。對於某些應用， 底層紙卷可具有大於約60 Coresta，或大於約80 Coresta 之知1氣率’或甚至更尚之透氣値。 又參考第2圖’紙卷進一步包括在沿第1圖之煙支22 的分隔位置處之添加材料區對（如相對區對3 4 d、3 6 d )。 各對長方形區（例如34a與36a- -後者在第1圖中無法 見到）界定圓周區域3 1 (例如區域3 1 a )。帶狀區域3 1 a之 「寬度」係自區域31a之前緣7(距鄰接之炭最近）測量 至後緣9(距鄰接之炭最遠）。較佳爲區域（例如31a)之 寬度爲約5.5毫米至約12毫米，更佳爲約7毫米至約10 毫米’而且最佳爲約8毫米至約9毫米之範圍。此外在各 圓周區域（如區域3 1 a )處，區3 4 a與3 6 a係沿圓周方向分 隔’使得其在煙支22上形成時沿卷紙24之相對側以相互 相對關係配置。較佳爲各區34a、36a沿圓周方向（即相對 紙卷之交叉面）延伸交叉面之約5毫米至約9毫米，更佳 爲交叉面之約6毫米至約7毫米的範圍。 應注意，在此所述各種具體實施例之尺寸時習慣上「 寬度」係按煙支之縱向方向延伸，而圓周方向之尺寸係示 爲「橫向」或「交叉方向」或「交叉面」。 又應注意，相鄰區域3 1 a、3 1 b間之底層紙卷區域3 3 及各區域內相對區間（如區域31b之相對區34b、36b之間 )之區域較佳爲絕對不包含此區域（例如區34b、36b )之 200932129 添加材料。 相鄰區域間（如區域3 1 a、3 1 b之間）之縱向距離係稱 爲帶狀分隔33’其較佳爲約4毫米至約12毫米，而且更 佳爲約6毫米至約8毫米。 較佳爲各區域31之各相對區34、36與前一列或區域 按一定程度偏置（依照以下之教示），而且沿特定煙支建立 充分數量之區域31 (依照帶狀區域寬度及帶狀區域分隔寬 度），其在將香煙物品置於基台上時沿煙支2 2出現至少一 個其中各對區34係實質上沿煙支22定向之位置1〇1，如 第1圖之相對區對34b、36b。其係在最易發生自熄之煙支 2 2的此部分（位置1 0 1 )或附近發生。其中最密集地出現 此定向之沿煙支22的位置在以下稱爲「定向熄煙區域1〇1 j ° 因爲香煙物品26可置於與第1圖所示不同之基台上， 及/或因爲其區圖案可不同，應了解對於煙支22之不同轉 動位置，定向熄煙區域1 〇 1可出現在沿煙支2 2之不同縱向 位置處。區圖案及帶狀分隔33可選擇使得沿煙支22可發 生超過一個定向媳煙區域101。 較佳爲各區34、36與36’包括不同之添加材料，以將 各區卷紙之透氣率降至〇.〇至約10 Coresta，更佳爲約7 Coresta或更小。 爲了本說明之目的，其將添加材料之圖案塗布於卷紙 2 4而得到改良之引燃性特性，而且亦得到改良之自熄特性 。引燃性爲如ASTM E 2 1 8 7-04 ,「用於測量香煙物品之引 200932129 燃強度的標準測試方法」所述之標準測試，其在此全部倂 * 入作爲參考。引燃性測量香煙物品在置於基台上時產生充 ' 分熱以維持煙支22之靜態燃燒的可能性。其希望爲低引燃 性値，因爲此値與悶燒香煙物品造成在底下基台中燃燒之 低可能性相關。 自熄在此指香煙物品在自由燃燒條件下之悶燒特性。 爲了評估自熄，其在23°C±3°C之溫度及55%±5%之相對濕 度（均應由記錄溫濕計監測）進行實驗室測試。排氣罩在 〇 測試期間去除燃燒產物。在測試前將欲測試之香煙物品在 5 5 %±5 %之相對濕度及23 °C ±3 °C下調節24小時。恰在測試 前將香煙物品置於玻璃燒杯中以確保自由空氣進出。 自熄測試係在封閉或測試箱內發生。其使用單口吸煙 機或電子打火機引燃測試用香煙物品。在測試期間，其以 設備或「夾角器」按〇度（水平）、45度及/或90度（垂直 )之角度夾持而夾持測試用香煙物品。在〇度、45度及90 度位置各測試二十（20)個香煙物品。如果使用超過一個設 備，則設備較佳爲安置成，香煙物品彼此反轉以避免相互 干擾。如果香煙物品在悶燒炭之前線到達水鬆紙前熄滅’ 則將此結果評爲「自熄」；另一方面，如果香煙物品持續 悶燒直到悶燒炭之前線到達水鬆紙，則將此結果評爲「未 熄」。如此例如9 5 %之自熄値表示9 5 %之測試香煙物品在自 由燃燒條件下呈現自熄；而20%之自熄値表示僅20%之測 試香煙物品在自由燃燒條件下呈現自熄。 自熄値可關於「〇度自熄値」、「4 5度自熄値」或「9 0 -10- 200932129 度自熄値」而敘述，其各爲在指定測試角度之自熄値。此 外自熄値可關於「自熄平均値」而敘述，其指三個角度位 ' 置之平均：即（i)「0度自熄値」，（ii)「45度自熄値」，及（iii) 「9 0度自熄値」之平均。指稱「自熄値」或未於0度自熄 値、45度自熄値、90度自熄値、或自熄平均値間加以區別 而可指其中任一。 在此使用之名詞「在自由燃燒條件下自熄」或「在自 由燃燒條件下之自熄」指在使此香煙接受或曝露於自由燃 〇 燒條件時，不噴煙而使悶燒香煙熄滅。 如目前所了解，根據此說明之交錯添加材料區可將香 煙物品2 0 (參見第1圖）設計成，具低引燃値與低自熄値 之有利組合。添加材料之低透氣率區的圖案提供沿煙支22 長度之膜形成化合物區域，其可與基台合作而在置於基台 上時將點燃之香煙物品20熄滅，但是在吸煙者以自由燃燒 條件持香煙物品20時，這些添加材料區域（如膜形成化合 物）造成香煙物品20在統計上極少之場合下自熄。如此藉 〇 由根據根據此說明，對底層紙卷塗布膜形成化合物之圖案 30，香煙物品20可呈現低引燃性，同時保持所需之自由燃 燒品質或低自熄値。 爲了達成香煙物品所需引燃性及自熄特性，較佳爲如 第2圖所示，在底層紙卷24爲解開狀態時，或在底層紙卷 包含一捆尙未切成絲線之香煙紙時，將圖案30(參見第2 圖）塗布於卷紙之底層紙卷24，。此說明之一個目的爲提 供在形成煙支22時呈現不大於25之IP値及不大於50之 -11- 200932129 自熄値的卷紙。甚至更佳爲所得香煙物品之IP値不大於約 15;而且所得香煙物品之最佳IP値不大於約10。亦希望爲 • 較低之自熄値。關於此點，更佳自熄値小於約2 5 ;而最佳 自熄値小於約1 〇。 特別地參考第2圖，卷紙24之橫向尺寸係根據完成香 煙物品之直徑（約7毫米至約1〇毫米）加以選擇，及可在 約1毫米至約2毫米之縱向縫處重疊材料。例如若容許！ 毫米之重疊縫’則對圓周爲約25.6毫米之香煙物品，卷紙 〇 交叉紙卷尺寸可爲約27毫米。 其較佳爲將圖案塗布底層紙卷，將多個沿圓周方向延 伸區域31a、31b、31c、31d (由第2圖之虛線界定）配置 於沿煙支22之分隔位置處（參見第2圖之箭頭B)。添加 材料可塗布於底層紙卷之一或兩側。其較佳爲在煙支22之 額定長度出現三至六，而且最佳爲四至六或更多個區域31 。各圓周區域31a、31b、31c、31d沿煙支22具有小於煙 支22之額定長度的縱向節距（即沿煙支自一個區域開端測 〇 量至相鄰區域開端之長度）。藉由選擇額定長度之約25 %的 縱向節距’其在各煙支22上提供4個區域。 在各圓周區域（例如3 1 a )內提供至少兩個添加材料 區’例如34a、36a。應注意，其將全部圖式中之添加材料 區點刻以助識別；然而在香煙物品或此香煙物品之卷紙中 ’這些添加材料區可爲或非可目視識別。這些區各較佳爲 沿圓周方向分隔’使得在完成煙支22中區彼此相對。此外 對於各一組三區，例如31a、31b、31c，第二區域31b之區 •12- 200932129 34b、36b較佳爲自第一區域之區34a、36a沿圓周方向偏置 m 。此外第三區域31c之區34c、36c較佳係自第二區域31b ' 之區34b、36b沿圓周方向偏置，而且甚至進一步自第一區 域31a之區34a、36a按圓沿圓周方向偏置。 如第2圖所述，在此具體實施例中各添加材料區係沿 圓周方向自相鄰區域之添加區橫向地偏置一定距離，其爲 添加區之橫向尺寸的函數。各區具有沿煙支22測量之寬度 及按煙支22之圓周方向測量之橫向交叉面尺寸。對於此具 β 體實施例，區寬度小於結合區域之縱向節距。如在第2圖 所見到，縱向節距長度可大於對應區域之對應區寬。沿煙 支22之連續區域的添加區較佳爲自相鄰區域之添加區偏 置，因而界定沿相對底層紙卷邊緣傾斜之線覆蓋部分底層 紙卷之區域的圖案30。此外添加區之圖案本身可至少部分 地沿底層紙卷之長度重複。 在圖示之具體實施例（第2圖）中，各區係位於卷紙 24上，使得區集中在三條路徑34、36與38之一，此路徑 係以對應虛線3 4、3 6與3 8表示。如此例如路徑3 4通過六 個區34a、34b、3 4c、3 4d、34e、34f之對應幾何特點。各 區與其他區分隔，但是區或可彼此接觸。路徑34、36與 3 8彼此平行且相對卷紙24之側緣以銳角φ定向。應了解， 區36’較佳爲與區36相同，及係因通過第2圖所示之圖案 而造成’如區3 4沿一邊消失，而區3 4，沿相對邊出現。各 對交叉紙卷排列區，例如區34a、36a、或區34b、36b，可 覆蓋對應區域31a、31b之總表面積的約33%。對於長方形 -13- 200932129 區’各區在縱向方向或寬度較佳爲約8毫米至約ι〇毫米之 範圍，及在圓周父叉面方向爲約5毫米至約7毫米。區間 之縱向分隔33較佳爲在約4毫米至約12毫米，而且更佳 爲約6至約8毫米之範圍內。添加材料區之圓周分隔較佳 爲在約3毫米至約20毫米之範圍內，更佳爲在約5毫米至 約8毫米之範圍內，而且最佳爲在約5.5毫米至約7.0毫米 之範圍內。 在圍繞香煙形成卷紙24而製造煙支22時，在任何縱 Ο 向位置處之添加材料區較佳爲彼此分隔約180度。此外添 加材料區佔據之面積對總面積之比例實質上小於1 (此比 例在此定義爲「區面積比例」），總面積爲（i)對應區域3 1 d 與（Π)—側相鄰區域間圓形區域之和。較佳爲區面積比例在 小於約20%至小於約50%之範圍內，而且更佳爲小於約20% 至小於約35%之範圍內。更佳爲在某些具體實施例中，區 佔據面積對總面積之區面積比例可小於3 0%，而且甚至小 於25%。一般而言，在將低透氣率（即低Coresta)卷紙用 ^ 於煙支之處，其希望將區面積覆蓋比例保持低，因爲據信 高値（即較接近1 )增加主流煙氣中之一氧化碳濃度。 在形成卷紙24而製造煙支22時’路徑34、36、36’ 描繪第一螺旋路徑3 6/36’（第2圖之區36與36’組合形成 螺旋路徑36/36，）及第二螺旋路徑34(包含螺旋排列區34 )，其均如第7-9圖所示，繞軸A，亙煙支22之長度延伸。 螺旋路徑3 6/3 6’及34(如由第2圖所見到）具有螺旋角Φ 且彼此不交叉。較佳爲二螺旋路徑均可根據圍繞煙支22之 -14- 200932129 逆時鐘與順時鐘轉動之一。如所描述，在自點煙端觀看且 朝濾嘴端看時，路徑34、36’均自煙支22之濾嘴端開始根 據順時鐘路徑。 圖案30之區可藉由對卷紙之底層紙卷塗布一或多層 水性膜形成組成物以降低這些區之紙透氣率而形成。或者 亦可使用纖維素材料形成區。在使用膜形成組成物之處， 膜形成組成物較佳爲可包括水與高濃度閉塞劑，例如20% 至約5 0重量％。膜形成化合物可包括一或多種閉塞劑，如 澱粉、海藻酸酯、纖維素、或膠，而且亦可包括碳酸鈣作 爲塡料。在膜形成化合物爲澱粉時，約24%之濃度可爲有 利的。膜形成組成物可使用凹版印刷、數位印刷、塗覆、 或使用樣板之噴灑、或任何其他合適之技術塗布於卷紙24 之底層紙卷。例如可選擇美國專利申請案第n/500,918號 所述之膜形成化合物及塗布膜形成化合物之方法，其在此 全部倂入作爲參考’將圖案施加於卷紙之底層紙卷。如果 需要’則添加材料區可藉由印刷彼此連結或對齊之多連續 層（例如二或更多連續層）而形成。此外在使用層形成添 加材料區時’層中材料可爲相同或不同。例如一層可爲澱 粉而次層可爲澱粉與碳酸鈣（或反之）。 添加材料區之圖案3〇的目前較佳具體實施例描述於 第3圖。如同第2圖之具體實施例’第3圖之添加材料區 爲四邊形’特別是大致長方形。較佳爲在各區域3丨a、3 ! b ' 31c、31d施加至少二添加材料區，例如4〇a、40b，而在 完成之香煙物品中沿圓周方向分隔。各區4〇a、4〇b之圓周 -15- 200932129 尺寸較佳爲選擇在解開時小於底層紙卷24之交叉面的約 50%，而且最佳爲底層紙卷24之交叉面或煙支22之圓周 • 的約25%。在加入區40a、40b間之圓周分隔時，各區40a 、4 0b之圓周尺寸較佳爲底層紙卷24之圓周交叉面的約 5 0%。 較佳地，選擇區40a、40b之縱向長度加上區40a、40b 與區42a、42b間之縱向分隔33 (即縱向節距長度），使得 在香煙物品之煙支22的額定長度中出現三或四個區域31a 〇 、3 1 b、3 1 c、3 1 d，及使得相鄰區域之添加區彼此縱向地分 隔。較佳爲區（例如40a、40b )之縱向擴張或「寬度」（ 即先前定義之區寬度或區域寬度）爲約8毫米至約1〇毫米 之範圍。（i)區域31b之區42a、42b及（ii)區域31a之區40a 、40b的圓周偏置x較佳爲底層紙卷24之解開總交叉面的 約10%至約3 5%之範圍。更佳爲圓周偏置X爲底層紙卷24 之解開總交叉面的約12%至約3 5%之範圍。最佳爲圓周偏 置X爲添加區40a、40b之圓周尺寸或交叉面之半。其他區 〇 w 域31c、31d中之添加材料區同樣地進一步沿圓周方向彼此 偏置相同之偏置X。應注意，例如在3 1 d中，在底層紙卷 爲解開狀態時，添加材料區46a、46c之一在底層紙卷24 之兩個邊緣部分分開。 在區域31 a-3 Id中塗布之圖案較佳爲沿底層紙卷24之 長度重複。明顯地，如果圓周偏置X小於底層紙卷之交叉 方向寬度的12.5%，則超過4個區域對圖案30界定完整之 循環或相長度。反之，如果圓周偏置X大於1 2.5 %，則小 -16 - 200932129 於4個區域對圖案30界定完整之循環或相長度（如第 之圖案的情形）。 圖案30之進一步具體實施例（參見第4圖）使用 形添加材料區60a、60b，即實質上平行四邊形區。雖 卷紙形成煙支22時，區60a、62a彼此安置成大致螺 列，其平行四邊形60、62、64、6 6之構形卻可如所需 。即使可能失去大致螺旋感，仍可例如使用形狀之鏡 繞縱向反映）。同樣地，其可如所需改變平行四邊形區 度。然而在此具體實施例中，其通常可如其他具體實 所述而選擇區60、62、64、66、及區域31a-31d之圓 寸、圓周分隔或偏置、縱向尺寸、與縱向分隔。 圖案30之又另一具體實施例（參見第5圖）使用 四邊形添加材料區70、72' 74、76，即實質上梯形區 將卷紙組成煙支22時，在此再度可將大致梯型區70a 彼此安置成大致螺旋排列。此外可如所需選擇梯型區 72、74、76之實際形狀。例如可如所需改變梯形區之 及梯型區之比例。然而在此具體實施例中，其通常可 他具體實施例所述而選擇區70、72、74、76、及區域3U 之圓周尺寸、圓周分隔或偏置、縱向尺寸、與縱向分 較佳地，前緣7爲區70之兩個平行邊緣中較長者。 圖案30之又一個具體實施例（參見第6圖）使用 三角形添加材料區80、82、84、86。區域31a之大致 形區80a、80b可構成及安置成接觸次一相鄰區域31b 應大致三角形區82a、82b。如果所需之IP與SE特性 2圖 四邊 然在 旋排 選擇

致三角形區之交叉方向尺寸（即第6圖之由右至左），或 得悶燒香煙物品之燃燒炭遭遇三角形底線及在低透氣率 急劇增加（即第6圖之由左至右）。三角形區80、82、 、86之圓周分隔及這些三角形之大小可根據本說明他處 述之較佳範圍決定。此外三角形區可爲如圖所示等邊三 形或全等三角形或正三角形、或任何其他所需之三角形 狀。然而在此具體實施例中，其通常可如其他具體實施 所述而選擇區80、82、84、86、及區域31a-31d之圓周 寸、圓周分隔或偏置、及縱向分隔與偏置。較佳爲區80 三角形形式係定向以建立前緣4(距鄰接之碳最近）。 靜置於基台98上之香煙物品20的三個不同位置描 在低透氣率添加材料區與基台98間發生之合作。一個位 (參見第7圖）描繪根據本說明之香煙物品20的側視廣 香煙物品圍繞其縱軸轉動45度角（自第7圖左端起順時 )造成類似第8圖所示之正視圖。類似地，香煙物品20 一步轉動又45度角（亦自第7圖左端起順時鐘）造成凳 圖描繪之正視圖。在各第7-9圖中可見到，至少一對添 材料區在沿煙支22長度之位置位於香煙物品之側面上， 如第7圖之區92' 92，、第8圖之區94、94，、及第9圖 區96、96’ °在添加材料區實質上位於香煙物品之側面上 相 需 悶 大 使 丨品- 84 所 角 形 例 尺 之 述 置 I °

直徑實質上平行於基台98之表面。 添加材料區在沿香煙物品2 0之其他縱向位置處的 向顯示於第10及11圖。在第10圖中，添加材料區90 90’係安置成一區90接觸基台98。在自第7圖之右端觀 時，第7圖之香煙物品20的區94、94’亦如第10圖安置 在第11圖中，一區96’接觸基台98，但是另一相對區 係位於香煙物品20之上方。考量第7-9圖應了解，不論 有所述添加材料區圖案之香煙物品20的角度位置爲何， 少一對相對之添加材料區係如第1 0圖或第1 2圖所示， 這些位置間之轉動位置。此位置已在以上稱爲定向熄煙 域 1 0 1 〇 在香煙物品20存在於自由燃燒條件狀態（參見第 圖）時’區92、92’因其減低之透氣率而阻礙對煙支22 燃燒炭的氣流。另一方面，卷紙之底部104自由地使空 進入煙支22之側面而支持炭之燃燒。在將香煙物品20

DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present disclosure generally relates to a cigarette article, and more particularly to a pattern on a roll of paper to reduce the ignitability of a cigarette article when placed on a base. Cigarette items. [Prior Art] U.S. Patent No. 5,878, 754 and U.S. Patent No. 6,997,190, the disclosure of each of each of each of each of each of each of each of each of each of each of each of each of each of SUMMARY OF THE INVENTION A cigarette article includes a cigarette and a roll of paper formed from a bottom roll having a rated air permeability. Preferably, the additive material region is applied to the underlying paper roll in accordance with a pattern comprising a plurality of regions spaced longitudinally along the tobacco branch and spaced apart in the circumferential direction. Preferably, each zone includes at least two substantially opposing zones of added material which exhibit a lower gas permeability than the rated gas permeability. Preferably, the added material zone has sufficient size, shape and concentration of added material, and when the cigarette is smoldered and placed on the abutment, the cigarette has a tendency to extinguish at the corresponding area. For each of the first, second, and third continuous regions, the region of the second region is offset from the region of the first region in the circumferential direction. Further, the region of the third region is offset from the first and second regions in the circumferential direction. Preferably, the pattern is substantially continuous along the cigarette so that at least one region is disposed such that its additive material region is substantially at the side of the cigarette when the cigarette is placed on the base and viewed from one end. Preferably, the cigarette article exhibits an ignitability of no greater than about 25%, and is less self-extinguishing at about 5% of 200932129. The cigarette article according to the present disclosure preferably comprises a roll paper having a pattern formed of a low air permeability film forming compound. The pattern is selected such that when the cigarette article is placed on the abutment, the 'cigarette article self-extinguishes when the advancing combustion line reaches the one or more longitudinal positions in which the film-forming compound is present on the side of the cigarette article that is not in contact with the abutment, but has a film formation The side of the compound or agent does not cause the cigarette article to self-extinguish when the smoker holds the cigarette item. The pattern can therefore be selected by considering the impeding airflow of the cigarette article contacting the side or side of the abutment. Such a cigarette article can have reduced ignitability and a satisfactory free burning quality. The cigarette article can have a rounded or nearly circular cross-section, which means that any side or side of the cigarette article can be placed against the abutment, such as when placing the cigarette item on a surface or when placing a cigarette item casually. In this regard, the pattern described herein defines the side or side of the film forming compound that does not contact the abutment, regardless of the orientation of the cigarette article just as it contacts the abutment. Cigarette Articles Items may also have a non-circular cross section. The roll paper and its additive material zone may comprise a plurality of discrete shapes each extending no more than the length of the cigarette. At a plurality of spaced longitudinal positions along the cigarette, only the first and second pattern shapes are present on the longitudinal axis of the substantially vertical cigarette and the cross-section is taken. At this position, the first shape is disposed only on the first side of the cigarette article, and the second shape is disposed only on the second side opposite the first side of the cigarette article. The first and second shapes may be separated by substantially 180° and have a porosity that is substantially less than the porosity of the underlying paper roll. If desired, a plurality of discontinuous shapes can be arranged such that the cross-section through the cigarette crosses two of the discontinuous shapes that are less than 200932129. [Embodiment] According to the present description, the cigarette article 20 of the first embodiment (see Fig. 1) includes a cigarette branch 22. The cigarette 22 can include a tobacco filter and is surrounded by a roll of paper 24. One end of the cigarette item 20 can include a suitable filter 26 that is surrounded by a suitable tipping paper 27. The cigarette item 20 generally has a substantially circular cross section depending on the length of the cigarette item. Nonetheless, other cross-sectional shapes including, for example, elliptical shapes are within the scope of the present description. The cigarette 2 2 has a nominal length L measured from the edge of the tipping paper 2 7 along the longitudinal axis A of the cigarette article 20 to the free end of the cigarette branch 22. For example, the nominal length can range from about 60 mm to about 100 mm. The roll paper 24 includes a bottom paper roll that is generally permeable to air. The air permeability of the rolled paper is generally identified by the Coresta unit. The Coresta unit measures the paper air permeability in terms of volumetric flow rate per unit area (ie, square centimeters) per unit pressure difference (ie, water square fraction) (ie, cubic centimeters per second). The bottom paper roll of the conventional roll paper also has a known bottom weight, which is measured in grams per square meter, abbreviated as "gsm". The air permeability and bottom weight of the bottom paper rolls of typical cigarette articles commonly used in the industry are listed in the following table: Air permeability, Coresta unit bottom weight, gsm 24 25 33 25 46 25 60 26 For the purposes of this description, the preferred paper base paper Volume 24 has an air permeability of at least 200932129 of about 20 Coresta units. Preferably, the roll paper has a gas permeability of greater than about 3 〇 Celesta' such as a conventional base paper roll having a nominal air permeability of about 33 and about a coresta and a bottom weight of about 25 gsm. For some applications, the bottom roll may have a gas enthalpy of greater than about 60 Coresta, or greater than about 80 Coresta' or even more. Referring again to Figure 2, the paper roll further includes pairs of added material regions (e.g., relative zone pairs 34 d, 3 6 d) at the spaced locations along the tobacco branch 22 of Figure 1. Each pair of rectangular regions (e.g., 34a and 36a - the latter not visible in Figure 1) defines a circumferential region 3 1 (e.g., region 3 1 a ). The "width" of the strip region 3 1 a is measured from the leading edge 7 of the region 31a (closest to the adjacent charcoal) to the trailing edge 9 (farthest from the adjacent charcoal). Preferably, the region (e.g., 31a) has a width of from about 5.5 mm to about 12 mm, more preferably from about 7 mm to about 10 mm', and most preferably from about 8 mm to about 9 mm. Further, at each of the circumferential regions (e.g., the region 3 1 a ), the regions 34 4 a and 3 6 a are circumferentially separated so that they are disposed in the opposing relationship along the opposite sides of the roll paper 24 when formed on the cigarette branch 22. Preferably, each of the zones 34a, 36a extends from about 5 mm to about 9 mm in the circumferential direction (i.e., opposite the intersection of the rolls) from about 5 mm to about 9 mm, more preferably from about 6 mm to about 7 mm of the cross face. It should be noted that in the dimensions of the various embodiments described herein, it is customary for the "width" to extend in the longitudinal direction of the cigarette, and the dimension in the circumferential direction to be "lateral" or "cross direction" or "cross surface". It should also be noted that the area of the bottom roll area 3 3 between adjacent areas 3 1 a, 3 1 b and the relative sections of each area (such as between the opposite areas 34b, 36b of the area 31b) preferably do not contain this. The area (eg, zone 34b, 36b) 200932129 adds material. The longitudinal distance between adjacent regions (e.g., between regions 3 1 a, 3 1 b) is referred to as a ribbon separation 33' which is preferably from about 4 mm to about 12 mm, and more preferably from about 6 mm to about 8 Millimeter. Preferably, each of the opposing regions 34, 36 of each region 31 is offset from the previous column or region by a degree (in accordance with the teachings below), and a sufficient number of regions 31 are established along the particular cigarette branch (according to the width and band of the ribbon region) The area separation width), when the cigarette article is placed on the base, at least one position in which the respective pairs 34 are oriented substantially along the cigarette branch 2, as in the opposite section of FIG. For 34b, 36b. It occurs in or near this portion (position 1 0 1 ) of the most prone to self-extinguishing cigarettes 2 2 . The position along the cigarette branch 22 in which the orientation occurs most densely is hereinafter referred to as "directed smoke-out zone 1 〇 1 j ° because the cigarette article 26 can be placed on a different base than that shown in Fig. 1, and/or Since the pattern of the zones can be different, it should be understood that for different rotational positions of the cigarettes 22, the targeted extinguishing zone 1 〇 1 can occur at different longitudinal positions along the cigarette branch 2. The zone pattern and the strip-shaped partition 33 can be selected such that The tobacco branch 22 can occur in more than one oriented smoking zone 101. Preferably, each zone 34, 36 and 36' comprises a different additive material to reduce the air permeability of each zone to 〇.〇 to about 10 Coresta, Preferably, it is about 7 Coresta or less. For the purposes of this description, the pattern of the added material is applied to the roll paper 24 to provide improved ignition characteristics, and improved self-extinguishing properties. ASTM E 2 1 8 7-04, Standard Tests for "Standard Test Methods for Measuring Combustion Strength of Cigarette Articles 200932129", which is hereby incorporated by reference. The flammability measurement of the cigarette article creates a charge of heat when placed on the abutment to maintain the likelihood of static burning of the cigarette. It is expected to be low in ignitability because it is associated with a low probability of burning of the smoldering cigarette article in the underlying abutment. Self-extinguishing refers here to the smoldering characteristics of cigarette articles under free-burning conditions. In order to evaluate self-extinguishing, it was tested in the laboratory at a temperature of 23 °C ± 3 °C and a relative humidity of 55% ± 5% (both monitored by a recorded thermometer). The hood removes combustion products during the 〇 test. The cigarette items to be tested were adjusted for 24 hours at a relative humidity of 5 5 ± ± 5 % and 23 ° C ± 3 ° C before the test. Place the cigarette items in a glass beaker just prior to testing to ensure free air in and out. The self-extinguishing test takes place in a closed or test box. It uses a single-port smoking machine or an electronic lighter to ignite the test cigarette item. During the test, the device or the "angler" is clamped at a degree of twist (horizontal), 45 degrees, and/or 90 degrees (vertical) to hold the test cigarette article. Twenty (20) cigarette items were tested at twist, 45 and 90 degrees. If more than one device is used, the device is preferably positioned such that the cigarette items are reversed to each other to avoid mutual interference. If the cigarette item is extinguished before the line reaches the tipping paper before the smoldering charcoal, then the result is rated as "self-extinguishing"; on the other hand, if the cigarette item continues to smolder until the line reaches the tipping paper before the smoldering charcoal, then This result was rated as "not extinguished". Thus, for example, 5% self-extinguishing means that 95% of the tested cigarette articles exhibit self-extinguishing under free-burning conditions; and 20% self-extinguishing indicates that only 20% of the tested cigarette articles exhibit self-extinguishing under free-burning conditions. Self-extinguishing can be described as "self-extinguishing", "45 degrees self-extinguishing" or "9 0 -10- 200932129 degrees self-extinguishing", each of which is self-extinguishing at a specified test angle. In addition, self-extinguishing can be described as "self-extinguishing average", which refers to the average of three angles: (i) "0 degree self-extinguishing", (ii) "45 degree self-extinguishing", and (iii) The average of "90 degrees self-extinguishing". The reference to "self-extinguishing" may be self-extinguishing at 0 degrees, self-extinguishing at 45 degrees, self-extinguishing at 90 degrees, or self-extinguishing between turns. The term "self-extinguishing under free-burning conditions" or "self-extinguishing under free-burning conditions" as used herein means that when the cigarette is subjected to or exposed to a free-burning condition, the smoldering cigarette is extinguished without spraying. As is currently understood, the staggered additive material zone according to this description can be designed to provide a desirable combination of low ignition enthalpy and low self-extinguishing scented tobacco article 20 (see Figure 1). The pattern of the low permeability zone of the added material provides a film forming compound region along the length of the cigarette branch 22, which cooperates with the abutment to extinguish the ignited cigarette article 20 when placed on the abutment, but is free to burn in the smoker When the cigarette article 20 is held under conditions, these areas of added material (e.g., film forming compounds) cause the cigarette article 20 to self-extinguish in the case of statistically few. Thus, the cigarette article 20 can exhibit low ignitability while maintaining the desired free burning quality or low self-extinguishing by patterning the compound forming film of the underlying paper roll according to the description herein. In order to achieve the desired ignitability and self-extinguishing properties of the cigarette article, it is preferred that, as shown in Fig. 2, when the bottom paper roll 24 is in the unwrapped state, or in the bottom paper roll, a bundle of uncut cigarettes is included. In the case of paper, the pattern 30 (see Fig. 2) is applied to the bottom paper roll 24 of the roll paper. One purpose of this description is to provide a self-extinguishing roll paper that exhibits an IP 不 of no more than 25 and a -11-200932129 of no more than 50 when the cigarette branch 22 is formed. It is even more preferred that the resulting cigarette article has an IP値 of no greater than about 15; and the resulting IP of the cigarette article has an optimum IP値 of no greater than about 10. I also hope that it will be self-extinguishing. In this regard, it is better to self-extinguish less than about 2 5; and the best self-extinguishing is less than about 1 〇. Referring specifically to Figure 2, the transverse dimension of the roll paper 24 is selected based on the diameter of the finished smoking article (about 7 mm to about 1 mm) and the material can be overlapped at a longitudinal slit of from about 1 mm to about 2 mm. For example, if allowed! The overlapping seam of millimeters is for a cigarette article having a circumference of about 25.6 mm, and the roll paper cross-web roll size can be about 27 mm. Preferably, the pattern is coated with a bottom roll, and a plurality of circumferentially extending regions 31a, 31b, 31c, 31d (defined by the dashed lines in Fig. 2) are disposed at the separation position along the cigarette branch 22 (see Fig. 2). Arrow B). The added material can be applied to one or both sides of the bottom paper roll. It preferably has three to six peaks in the nominal length of the cigarettes 22, and preferably four to six or more regions 31. Each of the circumferential regions 31a, 31b, 31c, 31d has a longitudinal pitch along the tobacco branch 22 that is less than the nominal length of the tobacco branch 22 (i.e., the length from the beginning of the tobacco branch to the beginning of the adjacent region). Four regions are provided on each cigarette branch 22 by selecting a longitudinal pitch of about 25% of the nominal length. At least two regions of additive material ', such as 34a, 36a, are provided within each circumferential region (e.g., 3 1 a ). It should be noted that it adds points in the additive material in all of the drawings to aid identification; however, these areas of added material may or may not be visually identifiable in the cigarette article or in the roll of the cigarette article. These zones are each preferably separated in the circumferential direction such that the zones in the finished cigarette branch 22 are opposite each other. Further, for each group of three zones, for example, 31a, 31b, 31c, the zone of the second zone 31b, 12-200932129 34b, 36b, is preferably offset in the circumferential direction from the zones 34a, 36a of the first zone. Further, the regions 34c, 36c of the third region 31c are preferably offset in the circumferential direction from the regions 34b, 36b of the second region 31b', and are even further offset circumferentially from the regions 34a, 36a of the first region 31a. . As illustrated in Figure 2, in this particular embodiment each additive material zone is laterally offset from the additive zone of the adjacent zone by a distance along the circumferential direction as a function of the lateral dimension of the additive zone. Each zone has a width measured along the cigarette branch 22 and a lateral cross-sectional dimension measured in the circumferential direction of the cigarette branch 22. For this beta body embodiment, the zone width is less than the longitudinal pitch of the bond zone. As seen in Figure 2, the longitudinal pitch length can be greater than the corresponding zone width of the corresponding area. The addition zone along the continuous region of the tobacco branch 22 is preferably offset from the addition zone of the adjacent zone, thereby defining a pattern 30 that covers a portion of the underlying paper roll along a line that is inclined relative to the edge of the bottom roll. Furthermore, the pattern of the addition zone itself can be repeated at least partially along the length of the bottom roll. In the illustrated embodiment (Fig. 2), the zones are located on the roll paper 24 such that the zones are concentrated in one of the three paths 34, 36 and 38 which correspond to the dashed lines 34, 36 and 3. 8 said. Thus, for example, path 34 passes through the corresponding geometrical features of the six zones 34a, 34b, 3 4c, 3 4d, 34e, 34f. Each zone is separated from other zones, but zones may be in contact with each other. The paths 34, 36 and 38 are parallel to each other and are oriented at an acute angle φ with respect to the side edges of the web 24. It will be appreciated that the region 36' is preferably the same as the region 36 and is caused by the pattern shown in Fig. 2 such that the region 34 disappears along one side and the region 34 appears along the opposite edge. Each pair of intersecting paper roll alignment areas, such as zones 34a, 36a, or zones 34b, 36b, may cover about 33% of the total surface area of the corresponding zones 31a, 31b. For the rectangular -13-200932129 area, each zone preferably has a range of from about 8 mm to about ι mm in the longitudinal direction or width, and from about 5 mm to about 7 mm in the direction of the parent bifurcation. The longitudinal separation 33 of the interval is preferably in the range of from about 4 mm to about 12 mm, and more preferably from about 6 to about 8 mm. The circumferential separation of the added material regions is preferably in the range of from about 3 mm to about 20 mm, more preferably in the range of from about 5 mm to about 8 mm, and most preferably in the range of from about 5.5 mm to about 7.0 mm. Inside. When the tobacco branch 22 is formed around the cigarette to form the roll paper 24, the added material regions at any of the longitudinal direction positions are preferably separated from each other by about 180 degrees. In addition, the ratio of the area occupied by the added material area to the total area is substantially less than 1 (this ratio is defined herein as the "area ratio"), and the total area is (i) the corresponding area 3 1 d and the (Π)-side adjacent area. The sum of the circular areas. Preferably, the area ratio is in the range of less than about 20% to less than about 50%, and more preferably less than about 20% to less than about 35%. More preferably, in some embodiments, the ratio of the area occupied by the area to the total area may be less than 30%, and even less than 25%. In general, where low gas permeability (ie, low Coresta) rolls are used in cigarettes, it is desirable to keep the area coverage ratio low because it is believed that sorghum (ie, closer to 1) increases in mainstream smoke. Carbon monoxide concentration. The path 34, 36, 36' depicts the first spiral path 3 6/36' when the roll paper 24 is formed to form the cigarette 22 (the areas 36 and 36' of Figure 2 combine to form a spiral path 36/36,) and A two-helix path 34 (comprising a helical array region 34), which extends as shown in Figures 7-9, extends about the length of the axis A, the cigarette branch 22. The spiral paths 3 6/3 6' and 34 (as seen in Fig. 2) have a helix angle Φ and do not intersect each other. Preferably, the two helical paths are one of counterclockwise and clockwise rotations depending on the -14-200932129 surrounding the cigarette. As depicted, the paths 34, 36' each follow the clockwise path from the filter end of the cigarette 22 as viewed from the cigarette end and toward the filter end. The zone of pattern 30 can be formed by applying one or more layers of an aqueous film to the underlying paper roll to form a composition to reduce the paper permeability of the zones. Alternatively, a cellulosic material forming zone can be used. Where a film-forming composition is used, the film-forming composition preferably includes water and a high concentration occlusive agent, for example, from 20% to about 50% by weight. The film forming compound may include one or more occlusive agents such as starch, alginate, cellulose, or gum, and may also include calcium carbonate as a dip. When the film forming compound is starch, a concentration of about 24% may be advantageous. The film forming composition can be applied to the bottom paper roll of the roll paper 24 using gravure printing, digital printing, coating, or spraying using a template, or any other suitable technique. For example, a film-forming compound and a method of forming a film-forming compound described in U.S. Patent Application Serial No. 5/500,918, the entire disclosure of which is incorporated herein by reference in its entire entire entire entire entire entire entire entire entire entire content The addition of material regions can be formed by printing multiple continuous layers (e.g., two or more continuous layers) that are joined or aligned with each other if desired. Further, the materials in the layers may be the same or different when the layer is used to form the additive material. For example, one layer may be starch and the second layer may be starch and calcium carbonate (or vice versa). A presently preferred embodiment of the pattern 3 of the added material zone is depicted in Figure 3. As in the specific embodiment of Fig. 2, the additive material region of Fig. 3 is a quadrilateral shape, particularly a substantially rectangular shape. Preferably, at least two regions of added material, such as 4〇a, 40b, are applied to each of the regions 3丨a, 3! b' 31c, 31d, and are circumferentially separated in the finished cigarette article. The circumference of each zone 4〇a, 4〇b-15-200932129 is preferably selected to be less than about 50% of the intersection of the bottom paper roll 24 when unwound, and preferably the intersection of the bottom paper roll 24 or the smoke. About 25% of the circumference of branch 22. When circumferentially spaced between the joining zones 40a, 40b, the circumferential dimension of each zone 40a, 40b is preferably about 50% of the circumferential intersection of the bottom roll 24. Preferably, the longitudinal extent of the selection zones 40a, 40b plus the longitudinal separation 33 (i.e., the longitudinal pitch length) between the zones 40a, 40b and the zones 42a, 42b causes three occurrences in the nominal length of the cigarette article 22 of the cigarette article. Or four regions 31a 3, 3 1 b, 3 1 c, 3 1 d, and the addition regions of adjacent regions are longitudinally separated from each other. Preferably, the longitudinal extent or "width" of the zones (e.g., 40a, 40b) (i.e., the previously defined zone width or zone width) is in the range of from about 8 mm to about 1 mm. (i) The circumferential offset x of the regions 42a, 42b of the region 31b and (ii) the regions 40a, 40b of the region 31a is preferably in the range of from about 10% to about 35% of the total cross-section of the unwinding of the bottom paper roll 24. . More preferably, the circumferential offset X is in the range of from about 12% to about 35% of the total cross-section of the untwisted paper roll 24. Preferably, the circumferential offset X is the circumferential dimension of the addition zones 40a, 40b or half of the intersection. The additional material regions in the other regions 〇 w domains 31c, 31d are similarly further offset from each other by the same offset X in the circumferential direction. It should be noted that, for example, in 3 1 d, one of the additive material regions 46a, 46c is separated at the two edge portions of the bottom paper roll 24 when the bottom paper roll is in the unwrapped state. The pattern applied in the regions 31 a - 3 Id is preferably repeated along the length of the underlying paper roll 24. Obviously, if the circumferential offset X is less than 12.5% of the width of the cross-web of the underlying paper roll, then more than four regions define a complete cycle or phase length for the pattern 30. Conversely, if the circumferential offset X is greater than 12.5 %, then the small -16 - 200932129 defines a complete cycle or phase length for the pattern 30 in four regions (as in the case of the first pattern). A further embodiment of the pattern 30 (see Figure 4) uses shaped addition material regions 60a, 60b, i.e., substantially parallelogram regions. While the web forms the tobacco branch 22, the zones 60a, 62a are disposed substantially in a spiral of each other, and the configuration of the parallelograms 60, 62, 64, 66 can be as desired. Even if it is possible to lose a rough sense of the spiral, it can be reflected, for example, in the longitudinal direction using a mirror of the shape). As such, it can change the parallelogram area as desired. In this particular embodiment, however, it is generally possible to select the areas 60, 62, 64, 66, and the areas 31a-31d in a circle, circumferentially spaced or offset, longitudinal dimension, and longitudinally spaced as other specific implementations. Yet another embodiment of the pattern 30 (see Figure 5) uses a quadrilateral additive material region 70, 72' 74, 76, i.e., when the substantially trapezoidal region forms the rolled paper into the cigarette branch 22, the ladder pattern can again be used here. The zones 70a are placed in a substantially spiral arrangement with each other. In addition, the actual shape of the ladder zones 72, 74, 76 can be selected as desired. For example, the ratio of the trapezoidal zone to the ladder zone can be changed as desired. In this particular embodiment, however, it is generally described in his specific embodiment that the circumferential dimensions, circumferential separation or offset, longitudinal dimension, and longitudinal division of the selected regions 70, 72, 74, 76, and region 3U are preferably preferred. The leading edge 7 is the longer of the two parallel edges of the zone 70. Yet another embodiment of the pattern 30 (see Figure 6) uses a triangular addition material region 80, 82, 84, 86. The substantially shaped regions 80a, 80b of the region 31a can be constructed and arranged to contact the next adjacent region 31b which should be substantially triangular regions 82a, 82b. If the required IP and SE characteristics are shown on the four sides of the figure, the pattern is selected in parallel (the partial circumference of the application is parallel. At '72a 70, the skewness is 1-3 1 d. The approximate triangle has this -17- 200932129 requires that the substantially triangular regions 80a, 80b of the region 31a be longitudinally separated from the triangular regions 82a, 82b of the adjacent region 31b. Depending on the nature of the cigarette article design, it is also intended to orient the substantially triangular region to cause burning The burning charcoal of the cigarette article encounters the apex of the triangle, and gradually increases the cross-direction dimension of the triangular region (ie, right to left in Fig. 6), or the burning charcoal of the smoldering cigarette article encounters the triangular bottom line and the sharpness in the low air permeability. Increase (ie left to right in Figure 6). The circumferential separation of the triangular regions 80, 82, 86 and the size of these triangles may be determined according to the preferred range described elsewhere in this description. Further, the triangular region may be as shown in the figure. An equilateral triangle or a congruent triangle or an equilateral triangle, or any other desired triangular shape is shown. However, in this particular embodiment, it is generally possible to select regions 80, 82 as described in other embodiments. , 84, 86, and the circumferential extent, circumferential separation or offset, and longitudinal separation and offset of the regions 31a-31d. Preferably, the triangular shape of the region 80 is oriented to establish the leading edge 4 (closest to the adjacent carbon). The three different positions of the cigarette article 20 placed on the abutment 98 are depicted in cooperation between the low gas permeability additive material zone and the abutment 98. One bit (see Figure 7) depicts the side of the cigarette article 20 according to the present description. Depending on the longitudinal axis of the wide-volume cigarette item (rotating from the left end of Figure 7), a front view similar to that shown in Figure 8 is produced. Similarly, the cigarette item 20 is rotated by a 45-degree angle (also from the 7th). The left end of the figure is clockwise) causing a front view of the stool drawing. It can be seen in each of Figures 7-9 that at least one pair of additive material areas are located on the side of the cigarette article along the length of the cigarette branch 22, as shown in Fig. 7. The area 92' 92, the area of the eighth figure 94, 94, and the ninth area 96, 96' ° in the area of the additive material is substantially located on the side of the cigarette article. The rule of the rule is set to I ° Zhong Jin i 8 plus the case of -18- 200932129 Looking at the 96-to-or 14-position gas, the 92 domain region is at a position (Fig. 12), and the regions 92, 92' are substantially upward or substantially perpendicular to the surface of the table 98. The orientation of the regions 92, 92' is optimal. Depicted in Fig. 12, when viewed in cross-section, the opposing regions 92, 92' are located on opposite sides of the cigarette article 20, and are disposed substantially symmetrically with respect to the diameter of the tobacco branch 22, substantially parallel to the abutment 98. The surface of the added material zone at other longitudinal positions along the cigarette article 20 is shown in Figures 10 and 11. In Fig. 10, the additive material zone 90 90' is disposed as a zone 90 contacting the base 98. When viewed from the right end of Figure 7, the zones 94, 94' of the cigarette article 20 of Figure 7 are also placed in Figure 11 as in Figure 10, with one zone 96' contacting the abutment 98, but another relative zone Located above the cigarette item 20. Considering Figures 7-9, it should be understood that regardless of the angular position of the cigarette article 20 having the pattern of added material regions, a pair of opposing additive material regions are as shown in Figure 10 or Figure 2, these positions. The position of rotation between the two. This position has been referred to above as the directional extinguishing field 1 0 1 〇 When the cigarette article 20 is present in the state of free combustion conditions (see the figure), the 'zone 92, 92' hinders the burning of the cigarette 22 due to its reduced air permeability. The flow of charcoal. On the other hand, the bottom 104 of the roll paper is free to allow air to enter the side of the cigarette branch 22 to support the burning of charcoal. A very different situation occurs when the cigarette item 20 is placed on the base 98 (see Figure 13). At the base 98, the airflow is blocked from flowing upward to the bottom 90 of the cigarette article 20. Zones, 92' and abutments collectively define the cells 100, 102 through which the air can pass through the bottom paper roll. More specifically, the vertical region 100 between the bottom of the region 92 and the base 98, and the vertical region 102 between the bottom of the region 92' and the base 98 allow -19-200932129 air to pass through the smoldering charcoal of the cigarette 22. The area is substantially reduced. As a result of the lack of oxygen in the air, the smoldering charcoal self-extinguishes when the combustion reaches the relative 'additional material zone' placed as described in Fig. 13. When the additive material region does not contact the abutment 98, the rotational position of the cigarette 22 between the position depicted in Fig. 10 and the position depicted in Fig. 12 also has a substantially reduced air area for supporting char combustion, Fig. 2 Shows where the air inlet and outlet area is reduced to the maximum. Similarly, if the cigarette article is placed on the abutment 98 and any other areas of added material have a position substantially as shown in Figure 13, then the other pairs are also prone to self-extinguishing. However, when the cigarette article is placed on the base 98 such that one of the addition zones contacts the base 98 (essentially as shown in Figure 11), the addition zone can substantially limit the passage of air to the area of the bottom roll, and Compared to the occurrence in the smoke-extinguishing zone 101, the abutment 98 is less cooperative with the material that contributes to the reduction in area. In the above example, a roll paper having a pattern 30 formed thereon is discussed in a position where the cigarette article is placed on the base 98 in exactly one of three specified orientations (the orientation is separated (offset) by 45 degrees). The cigarette article 20 has reduced ignition, self-extinguishing, and improved free combustion quality. Of course, the discussion in this way is for simplicity. It will be readily appreciated that the pattern of the present description extinguishes the cigarette article regardless of the side of the abutment 98 and the extent to which it is not necessary to apply the film forming compound to the desired free burning quality of the cigarette article. It is understood that the region of the compound forming film relative to the cognition is not necessarily present at exactly 90 degrees from the side of the contact abutment 98. These zones may be concentrated closer to or farther from the side of the contact abutment 98, such as between about 60 degrees and 1 2 turns of the side of the contact pedestal -20-200932129. Furthermore, the ability to extinguish a cigarette item for a particular selection pattern may depend to a large extent on the length of the smallest added material (eg, film forming compound), rather than on the specific weight of the film forming compound by area at the longitudinal position. . For example, the length of the rectangular region of the specific design, the underlying paper roll, and the film forming compound used may be not less than about 5.5 mm. It can increase the amount of film forming compound used to improve the ignitability properties, but generally does not lose the free burning quality' and if desired, the paper can be coated with a igniting accelerator to support a higher degree of addition. Preferably, the zone of added material reduces the air permeability of the web by about Cor to about 10 Coresta. In the past, it was believed that the ratio of the airflow ratio of the bottom paper roll to the additive material range of 3:1 was insufficient to extinguish the cigarette article because the air permeability was not sufficiently reduced at the longitudinal position. However, when the additive material is located on the side of the cigarette article that does not contact the base 98, and when there is a base 98 underneath, the ratio of the air permeability may be sufficient to extinguish the cigarette article at the circumferential portion of the cigarette article.

The longitudinal position, which still has a sufficient amount of addition, and the zones can be used to extinguish the geometry of the cigarette article with the abutment 98 when the combustion line reaches the longitudinal position. It results in improved ignitability of cigarette articles and can be designed to ignite cigarettes that are not more than 25 percent. Nonetheless, when there is no abutment, the cigarette article does not self-extinguish and remains free to burn when the smoker holds the smoking article. Its made -21 - 200932129 improved self-extinguishing performance of cigarettes, and can be designed to self-extinguish cigarettes of not more than 50%, this self-extinguishing can be self-extinguishing average. The self-extinguishing of the temperature: can be much lower than the average of S E and can be less than 2 5 %. In the above specific embodiment, the cigarette article has a substantially circular cross section. Therefore, any side of the cigarette article is reliably on the base 98. However, the pattern of the teachings herein can achieve the above-mentioned combustion characteristics (not more than 25% of the ignitability and not more than 50% of E値) regardless of the portion of the cigarette article on the base 98. . Preferably, the pattern is selected such that when the bottom paper is wrapped around the cigarette 22, the film forming compound region appears at the opposite side of the one or more longitudinal positions of the cigarette 22 that does not contact the substrate 98. Preferably, it has a longitudinal position on the side having more than one film-forming compound to accommodate the position of the cigarette article on the abutment 98 after the portion of the article of cigarette having the burnt line has been advanced through the cigarette article, or When the cigarette article is placed on the abutment 98, the side additive material zone is always relatively close to the combustion line. If desired, the additive material region may also include other geometric shapes than the parallelogram, including, for example, elliptical shapes, other polygonal shapes, and the like. Further, the above-described helix angle Φ can be increased while keeping the dimensions of the regions the same as in the illustrated embodiment. This change places the zones in an overlapping pattern (or at least the zones next to each other). Alternatively, when the helix angle is the same as in Fig. 2 and/or the size shown in Fig. 2 is placed between the patches and along the paths 34, 36, 36' (so that there are 12 along the path 34 instead of When 6 patches are placed, a segmented spiral pattern can be formed by increasing the lateral dimension of the region or patch.
