【0001】
【発明の属する技術分野】
本発明は液剤を収容する室と粉末剤等を収容する室とが弱シール部等の仕切り手段で仕切られてなる複室容器の改良に関するものである。
【0002】
【従来の技術】
【技術文献1】特許第3060132号公報
【技術文献2】特許第3060133号公報
【技術文献3】特許第3016348号公報
従来より輸液容器等においては、変質防止を図るため液剤を収容する室と粉剤等を収容する室を弱シール部等の仕切手段で区画し、使用直前に両室を連通して液剤と粉剤等を混合溶解するようにした複室容器が多く使用されている。そして、内容物を取り出し得る口部は、製造工程上の都合を考慮して液剤を収容する室側に設けるのが通例である。
技術文献1には、液剤4を収容する室2に口部10を設けた複室容器の例が図1,図2に、同様な例が図7,図8に図示され、技術文献2には、液剤4を収容する室2に口部10を設けた複室容器の例が図1,図2に図示され、技術文献3には、液剤(薬液)を収容する第2の室2に、ポート部22と栓体23とからなる口部を設けた複室容器の例が図1,図2に図示されている。
【0003】
【発明が解決しようとする課題】
ところが、このような複室容器は、液剤を収容した室に手のひら等で外圧を加えることによって弱シール部を剥離し両室を連通させて、液剤と抗生物質等の粉剤とを混合溶解した後、これを注射針等で口部から取り出し投与するようにしたものであるが、まれに弱シール部を連通させずに口部から液剤のみを投与する可能性があるという問題点があった。
本発明はこのような事情を背景としてなされたものであり、本発明の目的は各室に収容されている粉末剤または固形剤と、液剤とを混合溶解した後に患者に投与するという適正な使用方法以外の方法では使用できないようにした複室容器を提供しようとするものである。
【0004】
【課題を解決しようとする手段】
このような目的を達成するためになされた本発明は下記のように構成される。

D 液剤を収容する室と、粉末剤または固形剤を収容する室とが連通可能な仕切り手段で仕切られてなる可撓性を有する複室容器において、前記仕切手段は1条もしくは所定間隔を隔てた2条以上の弱シール部で構成され、さらに液剤を収容する室には口部を設けないで粉末剤または固形剤を収容する室に口部を設けると共に粉末剤または固形剤を収容する室をバリアー性フィルムで覆うようにし、しかも前記口部は筒状部とバリアー性を有する栓体固定部とを備えて構成し、粉末剤または固形剤を収容する室をバリアー性フィルムで覆うに当たって、該室に取付けられた口部の筒状部を露出する部分がない状態に前記バリアー性フィルムで全周を覆うように両面から挟持すると共にバリアー性フィルムの内面側を密封させる状態に接着し、さらに前記栓体固定部のバリアー性はその内面部、外面部あるいは肉厚部内に全周にわたってバリアー性を有するリング状のバリアー部材を配置し、さらに栓体固定部の栓体取付側の開口端部をバリアー性フィルムで覆うようにして保持するようにしたことを特徴とする複室容器。
E A項〜D項のいずれか1項に記載の複室容器において、粉末剤または固形剤を収容する室と口部とを全体一緒にあるいは別々に覆うバリアー性フィルムは、該室と口部に対し空間部を生じ、かつ密封した状態に覆うように配置されるか、該室と口部に対し全体的には接着されていないが空間部が生じないように密着し、かつ密封した状態に覆うように配置されるか、該室と口部に対し融着、接着、蒸着、メッキ等により積層あるいは貼付された状態に覆うように配置されるかのいずれか1もしくは2以上である複室容器。
F A項〜E項のいずれか1項に記載の複室容器において、粉末剤または固形剤を収容する室と口部とを全体一緒にあるいは別々に覆うバリアー性フィルムは水分非透過性及び/又はガス非透過性を有する樹脂シートで構成されるようにした複室容器。

I A項〜H項のいずれか1項に記載の複室容器において、粉末剤または固形剤を収容する室と該室を覆うバリアー性フィルムとの空間部に乾燥剤、脱酸素剤の封入と一緒に、またはこれらを封入しないで空気、乾燥空気あるいは窒素ガス、アルゴンガス等の不活性ガスを封入するようにした複室容器。
ここに、「液剤を収容する室には口部を設けないで」とは、「その室に収容された液剤を取り出し得る口部を設けないで」ということを意味するものであり、液剤の取り出しに無関係の口部を設けることについては規制するものではない。
【0005】
【発明の実施の形態】
以下本発明の実施例を記載した図面に基づいて、発明の実施の形態を詳細に説明する。
図1、図2において、2は液剤4を収容する室、6は粉末剤(または固形剤)8を収容する室であり、室6には口部10が取り付けられている。室2は2枚の室構成シート12が周縁で溶着されて形成されるが、室構成シート12は図3に示すようにポリエチレン(以下PEと略記する)からなる外層14と、PEとポリプロピレン(以下PPと略記する)との混合樹脂からなる内層16とからなる多層フィルムである。
【0006】
一方室6は2枚の前記室構成シート12が下方に伸び、溶着されて構成される。すなわち、前記室構成シート12を2枚重ね合わせ、その周縁部を溶着すると共に、その中間部において横方向に、周縁部より強度が小さくなる状態に溶着し、かつその溶着部は図2、図4に示すように間隔を隔てた2本の筋条をなすようにして、仕切り手段としての弱シール部18、20を形成し、弱シール部18、20を境にして室2と室6が形成される。
【0007】
室2には液剤4が封入されると共に室6には粉末剤8が封入され、さらに室6は口部10と一緒に被覆シート22で密封状態に覆われ、室構成シート12と被覆シート22との間に形成される空間部24には乾燥剤26と脱酸素剤28とが封入されている。空間部24には、乾燥剤や脱酸素剤の封入と一緒にあるいは、これらを封入しないで空気や乾燥空気、窒素ガス、アルゴンガス等を充填してもよい。
【0008】
被覆シート22は図5に示すように、内層32がPEで、外層34が水分非透過性、ガス非透過性のバリアー性フィルムからなる多層フィルムであり、バリアー性フィルムとして例えばポリエチレンテレフタレート(以下PETと略記する)とポリ塩化ビニリデンとPEの3重層または、PETとポリビニルアルコールのシリカ蒸着フィルムとPEの3重層およびアルミ加工フィルム等が使用されている。そして2枚の被覆シート22は、室6を覆う状態に配置され、その左右と下部が室6に封入された粉末剤に溶着熱が及ばないように溶着されると共に、上部が弱シール部18、20の中間部に溶着され、シールされた構造をなしている。
【0009】
従って、溶着時に弱シール部18、20上に重ねて溶着することが回避できると共に収容された粉末剤の熱変性が防止できる。シールをする際被覆シート22内の空間部24に乾燥剤26と脱酸素剤28が封入される。乾燥剤としては、例えばシリカゲル、ゼオライト等を成分とする市販のものが使用可能であり、また、脱酸素剤としても市販のもの、例えば三菱瓦斯化学社製「エージレス」(登録商標)やアモルファス銅を用いた脱酸素剤等が使用できる。
【0010】
なお、各部の溶着に当たって溶着温度は、室6の周縁部と室2の周縁部とが最も高く、弱シール部18、20はこれより低くする。一方、室構成シート12と被覆シート22との溶着部の溶着温度は、弱シール部18、20の中間部の内層フィルム16同士が溶着しない程度、すなわち弱シール部18、20の溶着温度より若干高い温度を限界とするよう設定される。その結果溶着強度は、室6、室2、被覆シート22の各周縁部と、室構成シート12、被覆シート22間の接着部とがほぼ等しく、弱シール部18、20はこれらより弱くなる。
【0011】
上記実施例の複室容器は、例えば図6の製造例に従ってつくられる。すなわち、(イ)内層がPEとPPとの混合樹脂で、外層がPEの多層フィルムである室構成シート12を2枚重ね合わせ、溶着温度約170〜200℃で3方の周辺シールを行うと共に中間部を仕切るための2条のシールを溶着温度約110〜130℃で所定間隔を隔てて行い弱シール部18、20を形成し、さらに口部10を取り付ける。(ロ)ついで、口部10を有しない区画内に液剤4を充填し、両区画の側部をシールして高圧蒸気滅菌または熱水滅菌等の加熱殺菌を行なう。(ハ)加熱殺菌後、何も充填していない室40の側部を無菌条件下でカットし、充填口を設ける。なお、必要に応じて内部を乾燥する。(ニ)次に、粉末剤8を無菌条件下で室40内に入れ、側部をシールする。しかる後、室40の前後両外側に内層がPEで外層がポリ塩化ビニリデンとPPの2重層をなす水分非透過性およびガス非透過性のバリアー性フィルムからなる被覆シート22を溶着して取付ける。なお、弱シール部18、20に沿って溶着する部分は、弱シール部18、20の中間の位置とし、この弱シール部に重ならないようにして130〜135℃で溶着される。(ホ)その後、乾燥剤26と脱酸素剤28を、室40を構成する室構成シート12と被覆シート22の間の空間部24に入れてから側部をシールして密封する。この際、空間部の酸素を除去するため、N置換するのが好ましい。
なお、上記製造例において、各溶着温度は、フィルムの材質および溶着強度の設定等により、それぞれ最適な温度範囲が選択されるものであり、上記溶着温度範囲に、何ら限定されるものではない。
【0012】
以上のように構成された複室容器の実施例は、以下のようにして使用する。
液剤4が収容された室2に指や手のひら等で一定の圧力を加えることにより弱シール部18、20が剥離し、室2と室6が連通され、液剤4と粉末剤8が無菌状態で混合されて溶解する。しかる後、被覆シート22を破ってから注射針等を複室容器の口部10に刺し込めば、液剤4と粉末剤8の混合溶解液が取り出し得るようになり、患者への投与が可能となる。
【0013】
上記実施例においては、図1に示すように室2には液剤4が、室6には粉末剤8が収容されているが、液剤4と粉末剤8とを混合溶解した後でなければ投与することは実現不可能である。従って、液剤4のみを投与するなど誤った使用はあり得ない。というのは、複室容器は注射針等をその口部に突き刺して内容液を流出させて使用するのが普通であるが、口部10に注射針を突き刺しても、弱シール部18,20が閉ざされているときには、図1に示すように口部10を設けている室6には粉末剤8が収容されているので、注射針により粉末剤を流出させることは不可能である。すなわち、液剤と粉末剤とを混合溶解して液体としなければ、注射針で内容物を取り出すことができず、投与できないからである。また、液剤4を収容している室2には口部が設けられていないので液剤8のみを誤って投与することもあり得ない。
上述のように、液剤と粉末剤とを混合溶解してから投与するという正しい使用方法によらなければ使用できず、間違いようがないという利点がある。また、弱シール部18,20が閉ざされているときには、室6には粉末剤が収容されているので口部10に注射針を差し込む以前に、目視により間違いに気付く筈である。
従って、従来の複室容器のように、弱シール部を連通させずに口部に注射針を刺し込み、口部から液剤を取り出すという可能性がなくなり、弱シール部を剥離し両室を連通させて、液剤と粉剤等を混合溶解した後、これを注射針等で口部から取り出し投与するという適正な使用方法によらなければ、使用できないという利点がある。
【0014】
室6の室構成シート12は外層がPE、内層がPEとPPとの混合樹脂からなる水分透過性、ガス透過性の多層フィルムから構成され、口部10もPEやPPで構成され、同様に水分透過性やガス透過性を有するが、これら室6と口部10は、水分非透過性,ガス非透過性のバリアー性フィルムで構成された被覆シート22で覆われ密封されているので、粉末剤8の吸湿防止や酸化防止を図ることができる。また、上述のように被覆シート22は水分非透過性、ガス非透過性のバリアー性フィルムで構成されると共に、室6の室構成シート12は水分透過性、ガス透過性の多層フィルムから構成されているので乾燥剤、脱酸素剤はそれぞれ粉末剤の乾燥や酸化防止を効率よく行なうことができる。さらに、被覆シート22の一方を透明のバリアー性フィルムとすれば室構成シート12は透明であるから、内部の状態を目視できて好都合である。
【0015】
さらに詳しく述べれば、粉末剤(又は固形剤)が吸湿性を有する場合は、室6を構成するシートは水分透過性、被覆シート22は水分非透過性、空間部24には乾燥剤を封入し、粉末剤が易酸化性を有する場合は、室6を構成するシートはガス透過性、被覆シート22はガス非透過性、空間部24には脱酸素剤を封入する。なお、被覆シート22は水分非透過性とガス非透過性の両方を有し、かつ室6を構成するシートは水分透過性とガス透過性の両方を有するようにすれば、粉末剤(又は固形剤)が吸湿性を有する場合でも易酸化性を有する場合でもどちらでも使用することができ、使用前容器の在庫管理が容易になるという利点がある。
【0016】
上記実施例の粉末剤として例えば、抗生剤、抗癌剤、ステロイド剤、血栓溶解剤またはビタミン剤等の易酸化性、易熱変性の物質が挙げられ、液剤としてこれらの溶解液または希釈液、例えば生理食塩液やブドウ糖液および注射用蒸留水などが挙げられる。また、室6に封入する粉末剤に代えて固形剤を使用することも可能であり、同様な効果が得られる。
【0017】
室6を構成するシートとしては、上記実施例に記載された多層フィルム以外にも、PE、PPおよびこれらの混合樹脂から選ばれる一種以上の組合せによる単層もしくは多層フィルムを使用することも可能であり、好ましくは、室6を構成するシートの内層を直鎖状低密度ポリエチレン(以下LLDPEと略記する)とPPとの混合樹脂とし、外層をLLDPEとした2層フィルムを用いることができる。被覆シートにはポリ塩化ビニリデン、PET、アルミ加工フィルム、エチレンビニルアルコール共重合体(EVOH)、シリカ蒸着フィルムの単層もしくは 多層のシートを使用することも可能である。なお、室6を構成するシートと被覆シートの接着を良好にするために少なくとも被覆シートを多層フィルムとし、被覆シートの最内層の材質と室6を構成するシートもしくは同シートの最外層の材質とを同一にすることが望ましい。例えば、室6を構成するシートの最外層がLLDPEの場合、被覆シートの最内層にはLLDPEを用いることが望ましい。また、被覆シートの一部または全部にアルミ加工フィルムを使用した場合には、内部を遮光することが可能であり、薬剤の変質防止等に優れた効果を示す。
【0018】
また、前記実施例では、室6を構成するシートは室2の室構成シート12を下方に延長して使用しているが、図7に示すように、継ぎ合わせて使用してもよい。すなわち、図7(イ)に示すように室構成シート12と同様な多層フィルムの室構成シート13の2枚を下端部で重ね合わせ、その両側を同様な多層フィルムの室構成シート15で挟持して溶着し、弱シール部18、20を形成する。また、図7(ロ)に示すように、両室構成シート13の間と、両室構成シート15の間にインサートフィルム36、38を挟持して溶着し、両フィルム36、38間に弱シール部18、20を形成するようにしてもよい。
【0019】
図8は本発明の他の実施例を示す。前記実施例は室6と口部10を一緒に被覆シート22で覆ったものであるのに対し、これは室6を被覆シート23で、口部10を被覆シート21で覆ったものである。被覆シート23と21は異なった材質のものを選択できる利点があり、また室6自体を被覆シート23で密着した状態に覆ったり、口部10自体を被覆シート21で密着した状態に覆ったり、あるいはそれぞれに被覆シートとしてアルミフィルム等を貼付したりするのに好都合である。
【0020】
図9は本発明のさらに他の実施例を示す。図8に示す前記実施例から口部10の被覆シート21を取り外すと共に、口部10に代えて特開平11−128317号公報の図2記載の口部と同様な構成のバリアー性を備えた他の口部42を使用したものである。口部42は図10に示すように筒状部44と、その一端部側に形成された径のやや大きい栓体固定部46とを有し、筒状部44と栓体固定部46の肉厚部全周には連続して、バリアー性のシール層48が配置されると共に、栓体固定部46の開口端部にはゴム栓50がシール層48の一端側を取り巻くように設けられ、環状突部51により取付けられている。ゴム栓50の外側にはバリアー性を有する封止シート52が貼付されている。この口部42を使用すれば、バリアー性を備えているので、図8に示す被覆シート21を省略できる利点がある。バリアー性のシール層48は、栓体固定部46の内側部や外側部に配置してもよい。
なお、口部42に代えて口部10にバリアー性フィルムとして樹脂メッキ等の金属メッキ膜を施し、口部の入口にバリアー性の封止シートを貼付することも可能であり、また、口部10にはバリアー性を有する相溶性樹脂をコーチングすることも可能である。
【0021】
図11(イ)は本発明のさらに別の実施例を示すもので、粉末剤(または固形剤)を収容する室6を被覆シート23で覆うと共に口部56はその一部のみを覆うようにしたものである。口部56は、図11(ロ)に示すように、筒状部58とその一端部に固着された栓体固定部60を備え、栓体固定部60には肉厚部の全周にわたってバリアー性を有するリング状部材62が嵌め込まれて取付けられ、栓体固定部60の開口端部にはゴム栓63がリング状部材62を取り巻くように設けられ、環状突部64により取付けられている。ゴム栓63の外側にはバリアー性の封止シート66が貼付されている。このように構成された口部56は、図11(ロ)、(ハ)に示すように筒状部58が前後両側の2枚の被覆シート23により挟持された状態に、かつ筒状部58が露出しないで、しかも被覆シート23内が密封されるように接着されて、被覆シート23が取付けられる。図11(ロ)において被覆シート23に付した2点鎖線の斜線部は、2枚に重ねた被覆シート23同士の接着部分を示す。なお、筒状部58には図11(ハ)に示す場合に限らず、筒状部58を挟持する状態に接着された、室6を構成する室構成シート12の上に、被覆シート23が重ねて接着される場合もある。
【0022】
本実施例によれば、筒状部58はバリアー性を有する被覆シート23により全周が覆われるので、筒状部にはバリアー性を有する層等を配置する必要がないという利点がある。また、栓体固定部60には全周にわたってバリアー性のリング状部材62を配置すると共に開口部にはバリアー性の封止シート66を貼付しているので、栓体固定部60のバリアー性、ひいては口部56全体のバリアー性を保持することができる。
【0023】
リング状部材62としては、金属やガラス等、その他バリアー性を有する樹脂等を使用することが可能であり、またその配置する位置は、栓体固定部60の内側部や外側部等としてもよい。また、前記各実施例の粉末剤(または固形剤)を収容する室を覆うバリアー性フィルムとして、金属のメッキ膜、蒸着膜、溶射膜等の樹脂メッキの膜(層)や化学メッキのメッキ膜等を採用することも可能である。
以上本発明のいくつかの実施例について説明したが、本発明はこのような実施例に何等限定されるものではなく、本発明の要旨を逸脱しない範囲において種々なる態様で実施し得ることはもちろんである。
【0024】
【発明の効果】
本発明は上述の通り構成されているので、次に記載する効果を奏する。
口部は粉剤(または固形剤)を収容する室のみに設けられているので、液剤との混合溶解前に仮りにこの口部に注射針等を差し込んだとしても内容物(粉剤または固形剤)を取り出し得ないことは誰にしても明白であるから、このような不適当な使用は起こり得ないという利点がある。また、弱シール部が閉ざされているときには、口部を有する室には粉末剤が収容されているので、室を構成するシートや被覆シートを透明とすれば、口部に注射針を差し込む以前に、目視により間違いに気付き得る利点がある。
また、粉末剤や固形剤を収容する室のみならず、口部もバリアー性フィルムで覆うようにすれば、前記室を構成するシートだけでなく口部からの水分や酸素の透過を遮断し、粉末剤や固形剤の吸湿や酸化の防止を図り得る利点がある。さらに、粉末剤(または固形剤)を収容する室と口部とを別々にバリアー性フィルムで覆うようにすれば、それぞれ材質の異なるバリアー性フィルムを使用でき、その上に粉末剤(または固形剤)を収容する室のみをバリアー性フィルムで密着状態に覆うことが容易になるという利点がある。さらにまた、口部をバリアー性を備えた構成にすれば、口部をバリアー性フィルムで覆う必要がなくなく構造が簡単になり、さらに上記同様に粉末剤(または固形剤)を収容する室のみをバリアー性フィルムで密着状態に覆うことが容易になる。
また、口部は筒状部とバリアー性を有する栓体固定部とを備えて構成し、粉末剤(または固形剤)を収容する室をバリアー性フィルムで覆うに当たって、該室に取付けられた口部の筒状部を露出する部分がない状態に前記バリアー性フィルムで全周を覆うようにすれば、筒状部は全周をバリアー性フィルムで覆われるので、筒状部にはバリアー性の層等を配置する必要がなく、構造が簡単で製造コストを軽減できる利点がある。

[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings illustrating embodiments of the present invention.
In FIGS. 1 and 2, reference numeral 2 denotes a chamber for accommodating the liquid agent 4, reference numeral 6 denotes a chamber for accommodating the powder agent (or solid agent) 8, and an opening 10 is attached to the chamber 6. The chamber 2 is formed by welding two chamber constituent sheets 12 at the periphery. The chamber constituent sheet 12 includes an outer layer 14 made of polyethylene (hereinafter abbreviated as PE), PE and polypropylene (see FIG. 3). (Hereinafter abbreviated as PP) and an inner layer 16 made of a mixed resin.
[0006]
On the other hand, the chamber 6 is constituted by two chamber constituent sheets 12 extending downward and being welded. That is, the two chamber-constituting sheets 12 are overlapped, and the peripheral edge thereof is welded, and in a middle portion thereof, the sheet is welded in a state where the strength is smaller than that of the peripheral edge, and the welded portion is shown in FIG. As shown in FIG. 4, two weakly spaced streaks are formed to form weak seal portions 18 and 20 as partitioning means, and the chambers 2 and 6 are bounded by the weak seal portions 18 and 20 as boundaries. It is formed.
[0007]
The chamber 2 is filled with the liquid 4 and the chamber 6 is filled with the powder 8, and the chamber 6 is hermetically covered with the covering sheet 22 together with the opening 10. A desiccant 26 and an oxygen scavenger 28 are sealed in a space 24 formed between them. The space 24 may be filled with air, dry air, nitrogen gas, argon gas, or the like together with or without enclosing a desiccant or oxygen scavenger.
[0008]
As shown in FIG. 5, the covering sheet 22 is a multilayer film including an inner layer 32 made of PE and an outer layer 34 made of a moisture-impermeable and gas-impermeable barrier film. As the barrier film, for example, polyethylene terephthalate (hereinafter referred to as PET) is used. And a triple layer of polyvinylidene chloride and PE, or a triple layer of PET and polyvinyl alcohol with a silica vapor-deposited film and PE, and an aluminum processed film. The two covering sheets 22 are arranged so as to cover the chamber 6, and the left and right and lower portions thereof are welded so that the heat of welding does not reach the powder material sealed in the chamber 6, and the upper portion is weakly sealed 18. , 20 are welded and sealed in the middle.
[0009]
Therefore, it is possible to avoid welding on the weak seal portions 18 and 20 while overlapping, and to prevent heat denaturation of the stored powder. At the time of sealing, a desiccant 26 and an oxygen absorber 28 are sealed in the space 24 in the covering sheet 22. As the desiccant, a commercially available desiccant containing, for example, silica gel, zeolite, or the like can be used, and a commercially available deoxidizer such as “Ageless” (registered trademark) manufactured by Mitsubishi Gas Chemical Company or amorphous copper can be used. An oxygen scavenger or the like can be used.
[0010]
In the welding of each part, the welding temperature is highest at the peripheral edge of the chamber 6 and the peripheral edge of the chamber 2, and the weak sealing portions 18 and 20 are lower than this. On the other hand, the welding temperature of the welded portion between the chamber forming sheet 12 and the cover sheet 22 is such that the inner layer films 16 in the middle of the weakly sealed portions 18 and 20 are not welded to each other, that is, slightly higher than the welding temperature of the weakly sealed portions 18 and 20. Set to limit high temperature. As a result, the welding strengths of the peripheral portions of the chamber 6, the chamber 2, and the covering sheet 22 are substantially equal to the bonding portions between the chamber constituting sheet 12 and the covering sheet 22, and the weak seal portions 18, 20 are weaker than these.
[0011]
The multi-chamber container of the above embodiment is manufactured, for example, according to the manufacturing example of FIG. That is, (a) two chamber-constituting sheets 12 in which the inner layer is a mixed resin of PE and PP and the outer layer is a multilayer film of PE are laminated together, and a three-sided peripheral seal is performed at a welding temperature of about 170 to 200 ° C. Two seals for partitioning the intermediate portion are formed at a welding temperature of about 110 to 130 ° C. at predetermined intervals to form weak seal portions 18 and 20, and a mouth portion 10 is attached. (B) Next, the liquid agent 4 is filled in a section having no mouth portion 10, and the sides of both sections are sealed, and heat sterilization such as high-pressure steam sterilization or hot water sterilization is performed. (C) After the heat sterilization, the side of the chamber 40 in which nothing is filled is cut under aseptic conditions to provide a filling port. In addition, the inside is dried if necessary. (D) Next, the powder 8 is put into the chamber 40 under aseptic conditions, and the sides are sealed. Thereafter, a covering sheet 22 made of a moisture-impermeable and gas-impermeable barrier film, which is a double layer of polyvinylidene chloride and PP, is formed on both outer sides of the chamber 40 by welding. The portion to be welded along the weak seal portions 18 and 20 is located at an intermediate position between the weak seal portions 18 and 20 and is welded at 130 to 135 ° C. so as not to overlap the weak seal portions. (E) After that, the desiccant 26 and the oxygen scavenger 28 are put into the space 24 between the chamber forming sheet 12 and the covering sheet 22 constituting the chamber 40, and then the sides are sealed and sealed. At this time, it is preferable to perform N 2 substitution in order to remove oxygen in the space.
In addition, in the above-mentioned production examples, the optimum temperature range is selected for each welding temperature depending on the material of the film, the setting of the welding strength, and the like, and is not limited to the above-mentioned welding temperature range.
[0012]
The embodiment of the multi-chamber container configured as described above is used as follows.
By applying a certain pressure to the chamber 2 containing the liquid agent 4 with a finger or a palm or the like, the weak seal portions 18 and 20 are peeled off, the chamber 2 and the chamber 6 are communicated, and the liquid agent 4 and the powder agent 8 are sterilized. Mix and dissolve. Thereafter, if the injection needle or the like is pierced into the mouth portion 10 of the multi-chamber container after the covering sheet 22 is broken, the mixed solution of the liquid agent 4 and the powder agent 8 can be taken out, and the administration to the patient is possible. Become.
[0013]
In the above embodiment, as shown in FIG. 1, the liquid 2 is accommodated in the chamber 2 and the powder 8 is accommodated in the chamber 6. However, the administration is performed only after the liquid 4 and the powder 8 are mixed and dissolved. Is impossible to do. Therefore, erroneous use such as administration of only the liquid agent 4 is not possible. This is because a double-chambered container is usually used by piercing an injection needle or the like into its mouth to allow the content liquid to flow out. Is closed, the powder agent 8 is contained in the chamber 6 provided with the mouth portion 10 as shown in FIG. 1, so that the powder agent cannot be discharged by the injection needle. That is, unless the liquid preparation and the powder preparation are mixed and dissolved to form a liquid, the contents cannot be taken out with an injection needle and cannot be administered. Further, since the chamber 2 containing the liquid agent 4 is not provided with an opening, it is unlikely that only the liquid agent 8 is erroneously administered.
As described above, there is an advantage that it cannot be used unless there is a proper use method of mixing and dissolving the liquid preparation and the powder preparation before administration, and there is no mistake. Further, when the weak seal portions 18 and 20 are closed, since the powder is stored in the chamber 6, the user should visually notice the mistake before inserting the injection needle into the mouth 10.
Therefore, unlike a conventional multi-chamber container, there is no possibility that the injection needle is inserted into the mouth portion without removing the weak seal portion and the liquid agent is taken out from the mouth portion, and the weak seal portion is peeled off to communicate the two chambers. After mixing and dissolving the liquid preparation and the powder preparation, the medicine cannot be used unless it is taken out from the mouth with an injection needle or the like and administered.
[0014]
The chamber constituent sheet 12 of the chamber 6 has an outer layer made of PE and an inner layer made of a moisture-permeable and gas-permeable multilayer film made of a mixed resin of PE and PP, and the mouth portion 10 is also made of PE or PP. Although it has moisture permeability and gas permeability, the chamber 6 and the mouth 10 are covered and sealed with a covering sheet 22 made of a moisture-impermeable and gas-impermeable barrier film. The agent 8 can be prevented from absorbing moisture and preventing oxidation. As described above, the covering sheet 22 is formed of a moisture-impermeable and gas-impermeable barrier film, and the chamber constituting sheet 12 of the chamber 6 is formed of a moisture-permeable and gas-permeable multilayer film. Therefore, the desiccant and the oxygen scavenger can efficiently dry and prevent oxidation of the powder. Furthermore, if one of the covering sheets 22 is made of a transparent barrier film, the chamber constituting sheet 12 is transparent, so that the inside state can be visually checked, which is convenient.
[0015]
More specifically, when the powder agent (or the solid agent) has a hygroscopic property, the sheet constituting the chamber 6 is permeable to moisture, the covering sheet 22 is impermeable to moisture, and the space 24 is filled with a desiccant. When the powder has oxidizability, the sheet constituting the chamber 6 is gas permeable, the covering sheet 22 is gas non-permeable, and the space 24 is filled with a deoxidizer. Note that if the covering sheet 22 has both moisture impermeability and gas impermeability, and the sheet forming the chamber 6 has both moisture permeability and gas permeability, the powder (or solid) can be used. ) Can be used regardless of whether it has a hygroscopic property or an easily oxidizable property, and there is an advantage that inventory management of containers before use is facilitated.
[0016]
Examples of the powders of the above-mentioned examples include easily oxidizable and heat-denatured substances such as antibiotics, anticancer agents, steroids, thrombolytic agents or vitamins, and liquid solutions thereof or diluents such as physiologic agents. Saline solution, glucose solution, distilled water for injection and the like can be mentioned. Further, a solid agent can be used instead of the powder agent sealed in the chamber 6, and the same effect can be obtained.
[0017]
As the sheet constituting the chamber 6, besides the multilayer film described in the above embodiment, it is also possible to use a single-layer or multilayer film of one or more combinations selected from PE, PP and a mixed resin thereof. Yes, preferably, a two-layer film in which the inner layer of the sheet constituting the chamber 6 is a mixed resin of linear low-density polyethylene (hereinafter abbreviated as LLDPE) and PP and the outer layer is LLDPE can be used. It is also possible to use a single-layer or multi-layer sheet of polyvinylidene chloride, PET, aluminized film, ethylene vinyl alcohol copolymer (EVOH), or a silica-deposited film as the covering sheet. In order to improve the adhesion between the sheet constituting the chamber 6 and the covering sheet, at least the covering sheet is formed as a multilayer film, and the material of the innermost layer of the covering sheet and the material of the sheet constituting the chamber 6 or the material of the outermost layer of the same sheet are used. Are desirably the same. For example, when the outermost layer of the sheet constituting the chamber 6 is LLDPE, it is desirable to use LLDPE for the innermost layer of the covering sheet. Further, when an aluminum processed film is used for part or all of the covering sheet, the inside can be shielded from light, and an excellent effect of preventing deterioration of the medicine and the like is exhibited.
[0018]
Further, in the above-described embodiment, the sheets constituting the chamber 6 are used by extending the chamber constituting sheets 12 of the chamber 2 downward, but they may be jointly used as shown in FIG. That is, as shown in FIG. 7 (a), two lower sheets of the same multi-layer film chamber forming sheet 13 as the chamber forming sheet 12 are overlapped, and both sides thereof are sandwiched by the same multi-layer film chamber forming sheet 15. To form weak seal portions 18 and 20. Also, as shown in FIG. 7B, the insert films 36 and 38 are sandwiched and welded between the two-chamber constituent sheets 13 and between the two-chamber constituent sheets 15, and a weak seal is provided between the two films 36 and 38. The parts 18 and 20 may be formed.
[0019]
FIG. 8 shows another embodiment of the present invention. In the above embodiment, the chamber 6 and the mouth 10 are covered together with the covering sheet 22, whereas in this embodiment, the chamber 6 is covered with the covering sheet 23 and the mouth 10 is covered with the covering sheet 21. The covering sheets 23 and 21 have an advantage that different materials can be selected. Further, the chamber 6 itself is covered in close contact with the covering sheet 23, the mouth 10 itself is covered in close contact with the covering sheet 21, Alternatively, it is convenient to attach an aluminum film or the like as a covering sheet to each.
[0020]
FIG. 9 shows still another embodiment of the present invention. In addition to removing the covering sheet 21 of the mouth portion 10 from the embodiment shown in FIG. 8 and replacing the mouth portion 10 with a barrier property having the same configuration as the mouth portion described in FIG. 2 of JP-A-11-128317.
