Description

1253929 玖、發明說明: 【發明所屬之技術領域】 本發明係關於事先將藥液填充而成的塑膠製安瓿。更詳 言之,係關於可防止水蒸氣、水蒸氣以外之氣體、光線或 藥物(藥劑、藥液、該等之溶劑等)往安瓿内部浸入或往安 咅瓦外部滲出,或可防止安訊内所收藏之藥劑、藥液、溶劑 等往安瓿内表面吸收·吸附的填充藥液之塑膠安瓿及其製 造方法。 【先前技術】 以往,收藏藥液之安瓿多使用玻璃製者。但是,玻璃安 訊所收藏的藥液pH若較高,則具有引起鹼片(alkali flake) 溶出的問題。又,亦具有安瓿開封時易於手指產生切傷之 問題、及安瓿破損之危險性、開封時所產生的碎片混入藥 液中之危險性等之問題。更且,關於玻璃安瓿中所含之鋁 於藥液中溶出的危險性,於美國食品藥物管理局(F D A )亦提 出勸告。於是,近年來,漸漸以無此些危險性的塑膠製安 咅瓦取而代之。 形成安瓿的塑膠,一般係使用具有柔軟性、且已確立安 全性之聚乙烯(PE)、聚丙烯(PP)等之聚烯烴。PE和PP雖 然對於酸性及鹼性藥物為極安定的材質,但由於對氧、空 氣、二氧化碳氣體等之吸收·穿透性極高,故不適合作為 收藏易氧化藥劑、藥液的安瓿之形成材料。尤其是,於小 容量安瓿之情況,隨著水分之穿透而令内容量減少,產生 藥液濃度顯著增大之問題。 5 312/發明說明書(補件)/93-07/93111346 1253929 於是,對於輸液袋等之薄膜成形品、輸液瓶等之吹 形品的成形材料,已進行各種於容器採用賦予防止氣 水蒸氣穿透能力(阻擂性)之多層體(層合體)的檢討。 塑膠層合體在製造薄膜和薄片時被廣泛使用,但於 之製造上,使用薄膜和薄片並不適合,故而必然地, 瓿的製造上係採用吹出成形。 關於以吹出成形所形成的安瓿,係記載於日本專 2 9 1 4 8 2 6號公報和日本專利特開昭6 0 - 2 4 8 4 4號公報中 者記載的安瓿(衛生品用容器)為使用聚環狀烯烴予以 成形者,後者記載的安瓿(注射藥劑封入用容器)則具 乙烯-醋酸乙烯酯共聚物(E V A )之鹼化物所構成的防氧 為中間層。 但是,於此等文獻中,僅記載以吹出成形形成安瓿 旨。又,此等文獻中,安瓿的密封為在注入藥液或投 劑後,將其開口部以不會產生接縫之方式,以熱封予 口而達成。此類情況中,在形成熱封部時,有伴隨著 使得多層構造被破壞之虞,其結果,恐損害採用聚環 烴或具有EVA多層構造所伴隨之防止氣體穿透能力等 用·效果。 另一方面,填充藥液之塑膠安瓿的其他製造方法可 所謂的吹出填充密封法(Blow-Fill-Seal method)(參 本專利特公昭3 3 - 8 0 7 8號公報、特公昭3 6 - 5 9 8 5號公 羅美拉葛(rommelag)公司的網頁(「 Welcome rommelag(R)」,「 BTS Process-The bottelpack 312/發明說明書(補件)/93-07/93111346 出成 體和 安瓿 於安 利第 。前 吹出 備由 層做 的要 入藥 以封 加熱 狀烯 之作 列舉 照日 報、 ! t 0 (R) 6 1253929
Pr〇cess」,「2003年 3月 19日檢索」,網際網路<URL; http://www.rornmelag.com/>) 〇 吹出填充密封法係將筒狀之熔融塑膠型坯以主金屬模具 夾住而形成安瓿本體,接著填充藥液後,以頭金屬模具連 續進行安瓿頭部的形成和密封,由於連續進行安瓿的成 形、藥液的填充、安瓿的密封,故不僅與單純的吹出成形 法為大為不同之方法,且可更加無菌地達成藥液的注入, 並具備可實現大量生產的優點。 但是,以吹出填充密封法所製造之安瓿的公知者係由PE 和PP等之聚烯烴所構成的單層體。因此,不僅以吹出填充 密封法製造層合構造之安瓿,且對形成此類層合構造之一 層賦予對於氣體、水蒸氣、光線及藥物之防止穿透能力(阻 擋性),和對於藥物之吸收附著(吸收、吸附)之防止能力在 目前之狀況均未進行任何檢討(參照日本專利特公昭 3 3 - 8 0 7 8號公報、特公昭3 6 - 5 9 8 5號公報、前述之羅美拉 葛公司之網頁、(股)姆促爾(M u t u a 1 )之網頁(參照「包裝設 備-容器成形無菌填充系統」,「2 0 0 3年3月1 9日檢索」, 網際網路 < ϋ R L·,h 11 p : / / w w w . mutual, c ο . j p > )、日新製藥(股) 之網頁(「聚乙烯瓶」,「2 0 0 3年3月1 9日檢索」,網際網 路 <URL ; http://www.yg-nissin.co.jp/BFS.htm>)0 賦予對於氣體、水蒸氣、光線及藥物之防止穿透能力(阻 擋性),和對於藥物之吸收附著的防止能力之對策,例如為 於具有耐氣體穿透性之袋中收納保存安瓿、以具有防止光 線穿透能力(光阻性)之素材覆蓋或外裝安瓿表面之方法。 7 312/發明說明書(補件)/93-07/93111346 1253929 但是,此些方法中由於需要另外的收納袋和覆蓋表面的材 料,故製造步驟變得複雜,具有製造成本上升等之問題。 【發明内容】 於是,本發明之目的在於提供可防止水蒸氣、水蒸氣以 外之氣體、光線或藥物往安瓿内部浸入或往安瓿外部滲 出,或可防止安瓿内所收藏之藥劑、藥液、溶劑等往安瓿 内表面之吸收·吸附的填充藥液之塑膠安瓿及其製造方法。 用以解決上述課題之本發明之填充藥液的塑膠安瓿,係 具備具有可撓性的容器本體部、密封該容器本體部之口部 的融黏部、和連接設置於該融黏部所構成之融黏部扭斷用 把手部,其特徵,為上述容器本體部、融黏部及把手部為 使用具備二個以上之層之筒狀型坯並且整體成形所構成 者,上述容器本體部為將上述型坯以開口模夾住而成形, 且於其内部填充藥液後將口部密封而成,且,上述型坯之 至少一層為具有由防止氣體穿透能力、防止水蒸氣穿透能 力、防止光線穿透能力、防止藥物穿透能力及防止藥物吸 收附著能力所組成群中選出之至少一種特性的機能性層。 若根據上述之填充藥液之塑膠安瓿,由於在安瓿製造上 採用吹出填充密封法,故可無菌地達成藥液的注入、密封。 並且,上述本發明之填充藥液之塑膠安瓿,係與於吹出成 形所成形之空安瓿中填充藥劑後,將開口部以不會產生接 縫之方式融黏者(參照日本專利第 2 9 1 4 8 2 6號公報和特開 昭6 0 - 2 4 8 4 4號公報記載之安瓿)不同,不必擔心口部融黏 部位之層構造受到破壞。因此,本發明之填充藥液之塑膠 8 312/發明說明書(補件)/93-07/93111346 1253929 安瓿於安瓿成形後,亦可充分發揮所期之特性(阻氣性等)。 本發明中對於機能性層所要求之特性,可列舉防止氣體 穿透能力(阻氣性)、防止水蒸氣穿透能力(水蒸氣阻擋 性)、防止光線穿透能力(光線阻擋性)、防止藥物穿透能力 (藥物阻擋性)及防止藥物吸收附著能力。此些特性係如後 述般,根據使用作為型坯中之機能性層部分中的塑膠材料 和其調配劑之種類即可決定。 另外,於日本專利特開2 0 0 1 - 7 0 3 9 9號公報中,記載可將 把手部扭斷予以開封之填充藥液的塑膠安瓿,更且對於此 類安瓿,記載可以吹出填充密封法進行製造之要旨,和可 視需要予以多層化或賦予遮光性之要旨(段落[0 0 0 7 ]、 [0012])。但是,於該公報中,對於令型坯本身多層化、或 於型坯中配置具備上述機能之素材所構成之層以令安瓿全 體賦予所欲之阻擋性,則無任何具體的記載或教示。 於本發明之填充藥液之塑膠安瓿中,其成形所用之型坯 的最内層由含有聚烯烴或聚環狀烯烴之樹脂所形成為佳。 經由令型坯之最内層為含有聚烯烴或聚環狀烯烴之樹 脂,則可使得填充藥液之塑膠安瓿的最内層,亦為使用含 有聚烯烴或聚環狀烯烴之樹脂所作成的層。聚烯烴和聚環 狀烯烴為安定的材質,且安全性已被確立,故將此材質配 置於最内層之填充藥液的塑膠安瓿,可安全地應用為醫療 用之容器。 於本發明之填充藥液之塑膠安瓿中,較佳情況為,其成 形所用之型坯為其最内層除外之至少一層係調配著色劑、 9 312/發明說明書(補件)/93-07/93111346 1253929 紫外線吸收劑及氧吸收劑所組成群中選出之至少一種之藥 劑所構成的層,且比該層更内側之層為具有防止藥物穿透 能力之層。 經由令型坯最内層除外之至少一層作成調配著色劑和/ 或紫外線吸收劑之層,則可對填充藥液之塑膠安瓿賦予防 止光線穿透能力(光線阻擋性,具體而言為對於光、紫外線 等之阻擋性)。又,令型坯最内層除外之至少一層作成調配 氧吸收劑之層,則可對填充藥液之塑膠安瓿賦予防止氧穿 透能力(阻氧性)。 調配著色劑、紫外線吸收劑或氧吸收劑所構成之層因為與藥液 等直接接觸,恐令其内部所含之著色劑等溶出。但是,若根據上 述之填充藥液的塑膠安瓿,由於在調配著色劑等而成之層之更内 側配置具有防止藥物穿透能力之層,故可防止發生著色劑等在安 瓿所收藏之藥液中溶出的問題。 配置於比上述調配著色劑等之層更内側之具有防止藥物 穿透能力之層,可列舉後述的多元醇層、聚酯層及聚環狀 婦烴層。 於本發明之填充藥液之塑膠安瓿中,其成形所用之型坯 的機能性層以 (i ) 含有聚醯胺層者; (i i ) 含有多元醇層者; (iii)含有聚酯層者;或 (i v ) 含有聚環狀烯烴層者 為佳。 10 312/發明說明書(補件)/93-07/93111346 1253929 具備如上述(i )之含有聚醯胺層之機能性層時,可對填充 藥液之塑膠安瓿賦予防止氣體穿透能力和防止水蒸氣穿透 能力。因此,此類安瓿亦可適用於收藏例如易氧化、且不 可於氧存在下保存之藥液、和可能因水分含量變化而令藥 效等產生顯著變化之藥液的用途。 具備如上述(i i )之含有多元醇層之機能性層時,可對填 充藥液之塑膠安瓿賦予防止氣體穿透能力、防止水蒸氣穿 透能力及防止藥物穿透能力及防止藥物吸收附著能力。因 此,此類安瓿亦可適用於收藏例如不可於氧存在下保存之 藥液、和可能因水分含量變化而令藥效等產生顯著變化之 藥液的用途。 例如,於安瓿具備含有著色劑、紫外線吸收劑、氧吸收 劑等藥劑之層之情況,經由於比該層更内側處配置多元 醇,可防止上述藥劑於安瓿内所填充之藥液中溶出。 具備如上述(i i i )之含聚酯層之機能性層時,可對填充藥 液之塑膠安瓿賦予防止氣體穿透能力、防止水蒸氣穿透能 力、防止藥物穿透能力及防止藥物吸收附著能力。因此, 此類安瓿亦可適用於收藏例如不可於氧存在下保存之藥 液、和可能因水分含量變化而令藥效等產生顯著變化之藥 液的用途。又,經由令聚酯層使用作為安瓶的最内層,可 防止安瓿的最内層吸收或吸附藥物。 聚環狀烯烴具有防止藥劑之吸附·收附能力、防止藥物 穿透能力(藥物阻擋性)、防止水蒸氣穿透能力,且具有透 明性優良之優點,故嘗試將其應用於醫療用容器的形成材 11 312/發明說明書(補件)/93-07/93111346 1253929 料(曰本專利特開平5 - 2 7 7 1 5 4號公報)。因此,具備如 (i v )之含有聚環狀烯烴層之機能性層時,可對填充藥 塑膠安瓿賦予防止藥物穿透能力(藥物阻擋性)、防止 吸收附著能力、防止水蒸氣穿透能力。 又,例如,於安瓿具備含有著色劑、紫外線吸收劑 吸收劑等藥劑之層時,經由於比該層更内側處配置聚 烯烴層,可防止上述藥劑於安瓿内所填充之藥液中溶 將聚環狀烯烴層使用作為安瓿之最内層時,可防止 之最内層吸收或吸附藥物。更且,於此情形中,形成 層之聚環狀烯烴以使用玻璃轉移溫度(T g )為 1 1 0 °C以 為佳。將玻璃轉移溫度為上述範圍之聚環狀烯烴使用 内層,則可藉此令吹出填充密封法所使用之成形金屬 的接縫(主金屬模具與頭金屬模具之接縫)部分,於内 填充、密閉後,防止發生漏液。聚環狀烯烴之玻璃轉 度於上述範圍中,特別以6 0〜1 0 5 °C為佳,且以6 0〜 為更佳。 另外,於曰本專利特開平5 - 2 9 3 1 5 9號公報中,雖記 用聚環狀烯烴所成形之安瓿例,但該文獻中,對於以 填充密封法製造安瓿則無任何記載,且並未提出關於 漏液問題之產生及其解決方法。 然而,聚環狀烯烴中,玻璃轉移溫度超過 1 1 0 °C者 般而言對於彎曲應力缺乏耐性,具有脆之特徵。因此 由具備使用玻璃轉移溫度為 1 1 0 °C以下之聚環狀烯烴 成之最内層、和含有玻璃轉移溫度超過 1 1 0 °C之聚環 312/發明說明書(補件)/93-07/93111346 上述 液之 藥物 、氧 環狀 出。 安瓿 最内 下者 於最 模具 容液 移溫 8 0°C 載使 吹出 上述 ,經 所構 狀烯 12 1253929 烴之層的層合體形成填充藥液之塑膠安瓿,可在内容液填 充、密閉後,防止發生漏液,並且經由折彎或扭彎安瓿之 融黏部(薄壁部),則可輕易進行安瓿的開封操作。 另外,非環狀之烯烴所構成的聚合體,相較於聚環狀烯 烴,一般而言其成形體的柔軟性高,且时衝擊性優良。因 此,形成塑膠安瓿的層合體不僅為含有環狀烯烴之層,且 具備含有非環狀聚烯烴之層時,可提高塑膠安瓿全體的耐 衝擊性。 本發明之填充藥液之塑膠安瓿亦可為以可切折之薄壁部 連結的複數之安瓿連結體。經由作成此類連結體,例如, 可輕易管理收藏同種藥液的複數個安瓿。 本發明之填充藥液之塑膠安瓿,於機能性層為具有防止 水蒸氣穿透能力或防止藥物吸收附著能力之層時,可作成 内容量為0.5〜20毫升的安瓿供使用。即,關於具備上述 (i)之聚醯胺層、上述(ii)之多元醇層、上述(iii)之聚醋 層、或上述(i v )之聚環狀烯烴層做為機能性層的塑膠安 瓿,適合應用於内容量為0.5〜20毫升的小容量安瓿。其 原因在於,内容量0.5〜20毫升的安瓿,由於收藏液的絕 對量少,收藏於安瓿中之期間的溶劑揮散,且隨著藥劑吸 收附著至安瓿,產生收藏液之性狀顯著變化之問題,經由 設置防止水蒸氣穿透能力和防止藥物吸收附著能力等優良 之聚醯胺層、多元醇層、聚酯層或聚環狀烤烴層,可防止 此類問題的發生。 本發明之填充藥液之塑膠安瓿的製造方法之特徵為: 13 312/發明說明書(補件)/93-07/93111346 1253929 將具備二個以上之層、且其至少一層為具有由防止氣體 穿透能力、防止水蒸氣穿透能力、防止光線穿透能力、防 止藥物穿透能力及防止藥物吸收附著能力所組成群中選出 之至少一種特性之機能性層的筒狀型坯,以容器本體部成 形用之下方開口模夾住,並於其内部形成空洞藉以成形出 容器本體部後, 於該容器本體部中填充藥液,其次, 成形出將該容器本體部之口部以上方開口模夾住,且密 封該口部的融黏部、和連接設置於該融黏部而成之融黏部 扭斷用把手部。 若根據上述製造方法,則可無菌地達成對填充藥液之塑 膠安瓿内注入、密封藥液。並且,於填充藥液後,令安瓿 之口部融黏密封時,可不破壞多層塑膠的層構造地形成融 黏部。 因此,上述之本發明的製造方法極適於作為可防止氣 體、水蒸氣、光線及藥劑往内部或外部穿透,或安瓿内之 藥劑、藥液、溶劑等被内表面吸收或吸附之填充藥液之塑 膠安瓿的製造方法。 於本發明之填充藥液之塑膠安瓿的製造方法中,型坯以 使用下列為佳: (a) 其最内層為含有由聚烯烴或聚環狀烯烴之樹脂所形 成者,或 (b ) 其最内層除外之至少一層為調配由著色劑、紫外線 吸收劑及氧吸收劑所組成群中選出之至少一種藥劑 14 312/發明說明書(補件)/93-07/93111346 1253929 所構成之層,且比該層更内側之層為具備防止藥物 穿透能力之層者。 上述(a )之情況,令上述方法所得之填充藥液的塑膠安 瓶,可更加安全地用作醫療用之容器。 上述(a )中,最内層為由含有聚環狀烯烴之樹脂所形成 時,根據前述同樣之理由,該聚環狀烯烴以使用玻璃轉移 溫度 1 1 0 °C以下者為佳,且以使用玻璃轉移溫度 6 0〜1 0 5 °C者為更佳。 又,於上述(a)之情形中,根據前述同樣之理由,型坯以 使用具備玻璃轉移溫度 1 1 0 °C以下之聚環狀烯烴所形成之 最内層、和玻璃轉移溫度超過 11 0 °C之聚環狀烯烴所形成 之層者為佳。 上述(b)之情況中,可對根據上述方法,所得之填充藥液 之塑膠安瓿賦予防止光線穿透能力(對於光、紫外線等之阻 擋性)。 【實施方式】 其次,一邊參照圖式一邊詳細說明本發明之填充藥液之 塑膠安瓿的製造方法。 〈填充藥液之塑膠安瓿〉 圖1及圖2為顯示本發明之填充藥液之塑膠安瓿的一實 施形態圖。 圖1所示之填充藥液之塑膠安瓿1 0具備:具有可撓性的 容器本體部1 1、將容器本體部之口部1 2密封的融黏部1 3、 和連接設置於融黏部1 3而成的把手部1 4。 15 312/發明說明書(補件)/93-07/93111346 1253929 圖2所示之填充藥液之塑膠安瓿1 8係與圖1所示之安瓿 1 0同樣地,具備:具有可撓性之容器本體部1 1、將容器本 體部之口部1 2密封的融黏部1 3、和連接設置於融黏部1 3 而成的把手部1 4。此安瓿1 8之情況,側緣部1 7彼此為透 過可扭斷之接續部1 9而連接設置。 填充藥液之塑膠安瓿的把手部 1 4 為經由折彎或扭彎而 自融黏部1 3被切離。經由扭斷把手部1 4,自融黏部1 3及 容器本體部1 1切離,則可令容器本體部1 1的口部1 2開 放,而將容器本體部1 1内所密封·填充的藥液1 5收集、 排出。 另外,形成安瓿1 0、1 8的層合體,於具備含有玻璃轉移 溫度超過 1 1 0 °C之聚環狀烯烴層之情形中,根據前述之理 由,可令融黏部1 3切離的操作簡易。 形成填充藥液之塑膠安瓿的塑膠16之特徵為,其至少一 層為具有由防止氣體穿透能力、防止水蒸氣穿透能力、防 止光線穿透能力、防止藥物穿透能力及防止藥物吸收附著 能力所組成群中選出之至少一種特性之機能性層。 填充藥液之塑膠安瓿的側緣部1 7,係在該安瓿以吹出填 充密封法予以成形時,經由將型坯以金屬模具予以夾入而 形成者。填充藥液之塑膠安瓿1 8可使用例如具備對應於連 接設置安瓿數的頭部和模頭之多頭式頭部而成形。 〈安瓿形成材料〉 於本發明之填充藥液之塑膠安瓿中,該安瓿中所含之機 能性層係如前述,具有防止氣體穿透能力、防止水蒸氣穿 16 312/發明說明書(補件)/93-07/93111346 1253929 透能力、防止光線穿透能力、防止藥物穿透能力及防止藥 物吸收附著能力所組成群中選出之至少一種特性為其特 徵。關於此類特性、及該機能性層所使用之塑膠材料種類 的對應為如前述。 本發明可使用之聚醯胺並無特別限定,可列舉例如尼龍 -6、尼龍-6,6、尼龍-6, 12、尼龍-12、伸二曱苯二胺聚醯 胺等。 本發明可使用之聚酯並無特別限定,可列舉例如聚對酞 酸乙二酯(P E T )、聚萘酸乙二酯、聚對酞酸丁二酯(P B T )等。 本發明可使用之多元醇並無特別限定,可列舉例如聚乙 烯醇(PVOH)、乙烯-乙烯醇共聚合體(EVOH)等。 本發明可使用之聚環狀烯烴並無特別限定,可列舉乙烯 與二環戊二烯類的共聚合體、乙烯與降冰片烯系化合物的 共聚合體、環戊二烯衍生物之開環聚合體、複數之環戊二 烯衍生物之開環共聚合體、及該等之氫化物等。 於本發明中,上述例示之聚環狀烯烴中特別以使用乙烯 與降冰片烯系化合物之共聚合體的氫化物、或一種以上之 環戊二烯衍生物之開環(共)聚合體之氫化物為佳。經由使 用此類聚環狀烯烴,可令安瓿的強度和防止水分穿透能力 更加良好,且,可對安瓿賦予防止氣體穿透能力。 上述聚環狀烯烴可列舉例如具有一般式(1 )所示之重複 單位與一般式(Γ )所示之重複單位的聚合物、或具有一般 式(2 )所示之重複單位的聚合物。 17 312/發明說明書(補件)/93-07/93111346 1253929
