Description

本発明は、予め混合しておくと経時的に変質してしまう薬液、溶解液、食品等の成分を、使用時まで隔離して保管しておき、使用時に容易に混合できる容器の製造方法に関する。
また、本発明は、予め混合しておくと経時的に変質してしまう薬液、溶解液、食品等の成分を、使用時まで隔離して保管しておき、使用時に容易に他の薬液、溶解液、食品等が充填された容器に注入して混合するための容器の製造方法に関する。
The present invention relates to a method for producing a container in which components such as a chemical solution, a solution, and a food that change in quality when mixed in advance are isolated and stored until use, and can be easily mixed at the time of use. .
In addition, the present invention keeps chemicals, solutions, foods, and other components that will deteriorate over time when mixed in advance, and keeps them separated until they are used. The present invention relates to a method of manufacturing a container for injecting and mixing into a container filled with liquid, food and the like.

背景の技術Background technology

医療、化粧品、食品等の分野においては、予め混合しておくと経時的に変質してしまう薬液、溶解液、食品等の成分を、使用時まで複数の室に、隔離、密封して収容し、使用時に混合するシステムが多用されている。
近年、このようなシステ厶の一つとして、混合する成分を剥離可能なシールにより仕切られた複数の室を有する袋状容器のそれぞれの室に隔離、封入し、使用時に該剥離可能なシールを剥離して各室間を連通し、隔離封入された成分を混合するように構成した容器が提案されている。
In the fields of medicine, cosmetics, food, etc., components such as chemicals, solutions, foods, etc. that will deteriorate over time when mixed in advance are isolated and sealed in multiple chambers until use. A system that mixes when used is often used.
In recent years, as one of such systems, the components to be mixed are isolated and sealed in each chamber of a bag-like container having a plurality of chambers partitioned by a peelable seal, and the peelable seal is used in use. There has been proposed a container configured to peel and communicate between chambers and to mix separated and sealed components.

このようなシステムによれば、予め混合しておくと経時的に変質してしまう成分を変質しない状態で利用でき、さらに、内容物を外気に晒すことなく混合することができるので、内容物の変質、異物または細菌の混入を防止でき、人命にかかわる医療においては、特に、重用されている。
例えば、高カロリー輸液においては、主にアミノ酸を溶解した溶液と主に糖および電解質を溶解した溶液を、容易に開封可能なシールにより隔てられた2つの室にそれぞれ封入し、使用時に、容易に開封可能なシールを剥離して開封し、両者を混合し、点滴するシステムが採用されている。
According to such a system, it is possible to use a component that changes in quality over time if it is mixed in advance, and further, the content can be mixed without being exposed to the outside air. It is particularly important in medical treatments that can prevent alteration, foreign matter or bacteria, and are related to human life.
For example, in a high-calorie infusion, a solution in which amino acids are dissolved and a solution in which sugars and electrolytes are mainly dissolved are sealed in two chambers separated by an easily openable seal, respectively. A system has been adopted in which an openable seal is peeled off, opened, mixed, and instilled.

しかし、体に必要な成分の中には、糖、電解質、アミノ酸、脂肪乳剤の溶液のように容量の多い成分ばかりでなく、ビタミン類や微量金属類のように極少量であっても毎日必要とするものもある。これらの成分の中にも、混合して保管すると相互に作用しあって変質する恐れのある成分があり、相互に作用しあわない成分同士は混合するとしても、相互に作用し合う成分は隔離して保管することが好ましいことは言うまでもない。
従来より、高カロリー輸液療法を受けている患者には、ビタミン類や微量金属類も定期的に投与する必要があることが知られている。
このような成分の投与方法として、複数本のバイアル瓶またはプレフィールドシリンジに調整されたものを投与するか、隔離して封入された糖および電解質の溶液またはアミノ酸の溶液の中に予め分類して混合しておいたものを投与するか、糖および電解質の溶液またはアミノ酸の溶液の中に混合しきれない成分だけ別の硬質容器に封入し、これを袋状容器に一体化して設け、使用時に、前記硬質容器の一部を破壊して袋状容器と連通し、混合してから投与する等の方法がある。
However, some of the ingredients necessary for the body are necessary not only for components with a large volume such as solutions of sugar, electrolytes, amino acids and fat emulsions but also for daily use even with very small amounts such as vitamins and trace metals. There is also something to do. Among these components, there are components that may interact with each other and change their properties when mixed and stored. Even if components that do not interact with each other are mixed together, the components that interact with each other are isolated. Needless to say, it is preferable to store them.
Conventionally, it is known that vitamins and trace metals need to be regularly administered to patients receiving high calorie infusion therapy.
As a method of administration of such components, one prepared in a plurality of vials or prefield syringes is administered, or it is preliminarily classified into a sugar and electrolyte solution or amino acid solution enclosed in isolation. Only the components that cannot be mixed in the sugar and electrolyte solution or amino acid solution are sealed in another hard container, and this is integrated into a bag-like container. There is a method in which a part of the hard container is broken, communicated with the bag-like container, mixed and then administered.

ところが、別の容器に封入された何種類もの薬剤を使用時に袋状容器内に注入する方法では、薬液の取り違い、注入作業のミス、注入時の細菌汚染等が発生する危険があり、これを払拭するために煩雑な作業および煩雑な管理が必要にならざるを得ないという欠点を有している。
また、糖および電解質溶液またはアミノ酸の溶液の中に予め相互に反応しない成分を分類して混合する方法では、糖および電解質溶液またはアミノ酸の溶液の中に含まれる多数の成分との想定される全ての環境の元での相互作用がないことを長期に渡って確認する必要があり、そのために、多大な労力と時間が必要になるという欠点が有している。
However, in the method of injecting various kinds of medicines sealed in another container into the bag-like container at the time of use, there is a risk of occurrence of misplaced chemicals, mistakes in the injection work, bacterial contamination at the time of injection, etc. In order to wipe off, there is a disadvantage that complicated work and complicated management are unavoidable.
In addition, in the method of classifying and mixing components that do not react with each other in advance in the sugar and electrolyte solution or amino acid solution, all the possible components included in the sugar and electrolyte solution or amino acid solution are all considered. It is necessary to confirm over a long period of time that there is no interaction under the environment, and for this reason, there is a disadvantage that much labor and time are required.

また、隔離された多数の収容室を有する複室容器に多数の成分をそれぞれ隔離して収容した複室容器が提案されている(例えば、特開2002−160771、特開2002−191674参照)。
これらの提案は、小さい室の開封性と密封性とを両立することが困難なので、これを解決しようとするものである。
ところが、これらの提案の何れもが、小さい室の周囲の多くを剥離しないシールで囲む構造であることが共通しており、そのために、何れの提案も、開封性と密封性とを完全に両立するに至っていない。
In addition, a multi-chamber container has been proposed in which a large number of components are isolated and accommodated in a multi-chamber container having a large number of isolated chambers (see, for example, JP-A Nos. 2002-160771 and 2002-191647).
These proposals attempt to solve this problem because it is difficult to achieve both the opening and sealing of a small chamber.
However, it is common that all of these proposals have a structure in which much of the surroundings of a small chamber are surrounded by a seal that does not peel off. For this reason, both proposals are completely compatible with openability and sealing performance. It hasn't been done yet.

さらに、これらの提案は、複室容器自体の製造は容易であるものの、複室容器を作ってから内容物を充填するので、小さい室が内容物を充填しにくいというもう一つの欠点も解決していない。
すなわち、シートの充填口を除く周囲をシールして形成した容器は、一般に、容量が大きければ膨らみやすく、容量が小さければ膨らみ難い傾向にあり、また、シートを形成する樹脂が柔らかければ膨らみやすく、固ければ膨らみにくい傾向にあるので、小さな室にするのが排出性および容器のコンパクト性から好ましいビタミン類または微量金属類を封入するための室は、一般に輸液用のバッグに使用されるシートの柔らかさでは、膨らみ難く、ひいては充填および充填後のシールに煩雑な操作を必要とするものであった。
Furthermore, these proposals solve the other drawback that small chambers are difficult to fill because the multi-chamber container itself is easy to manufacture, but the contents are filled after the multi-chamber container is made. Not.
That is, a container formed by sealing the periphery excluding the filling port of a sheet generally tends to swell when the capacity is large, and hardly swells when the capacity is small, and easily swells when the resin forming the sheet is soft. Since it tends to be difficult to swell if it is hard, a chamber for enclosing vitamins or trace metals, which is preferable in terms of dischargeability and compactness of the container, is a sheet generally used for infusion bags With this softness, it was difficult to swell, and as a result, complicated operations were required for filling and sealing after filling.

さらに、一部のビタミン類のようなオートクレーブ滅菌やレトルト処理を行うと分解してしまう耐熱性のない成分を含む内容物を充填する場合、無菌充填が好ましいものの、これらの提案のものでは充填方法が難しいので工程が煩雑になり、無菌環境を整えることが困難であった。それでも、実現しようとすれば、多大な費用と労力を必要とするものであった。  Furthermore, when filling contents containing non-heat-resistant components that decompose when autoclaved or retort-treated, such as some vitamins, aseptic filling is preferred. However, the process is complicated and it is difficult to prepare an aseptic environment. Even so, if it was to be realized, it required a lot of money and labor.

特開2002−160771号公報(第2−4項、第1図)JP 2002-160771 (Section 2-4, FIG. 1) 特開2002−191674号公報(第2−3項、第1図)Japanese Patent Laid-Open No. 2002-191474 (section 2-3, FIG. 1)

そこで、本発明は、上記従来の問題点を解決しようとするものである。
すなわち、容易に開封可能なシールにより仕切られ、充填物が封入された一つまたは複数の室を有する混合用または混注用の容器において、使用前は、容易には開封せずに密封性維持し、使用時は簡単な操作で容易に開封できる内容物入りの複室容器の製造方法を提供することにある。
また、上記小さい室に内容物を容易に充填し密封できる容器の製造方法を提供することにある。
さらには、耐熱性がなくオートクレーブ滅菌ができない成分を含む内容物を充填する場合に、無菌充填が容易な容器の製造方法を提供することにある。
Therefore, the present invention is intended to solve the above-mentioned conventional problems.
That is, in a mixing or co-injection container having one or more chambers that are partitioned by an easily openable seal and filled with a filling material, the container is not easily opened and maintained in a sealed state before use. An object of the present invention is to provide a method for producing a multi-chamber container containing contents that can be easily opened by a simple operation during use.
Another object of the present invention is to provide a method for manufacturing a container that can easily fill and seal the contents of the small chamber.
It is another object of the present invention to provide a method for producing a container that can be aseptically filled when filling contents containing components that are not heat resistant and cannot be autoclaved.

L process to form
Outside the concave portion sealing means, the sheet formed product A and the sheet formed product B are bonded by a hard-to-open sealing means that cannot be easily opened or a peripheral sealing means comprising a hard-to-open sealing means and an easy-open sealing means. M step of forming another chamber that collectively surrounds one or a plurality of chambers sealed by the recess sealing means,
At least I process, J process, and K process are performed in this order, and then L process or M process is performed.

すなわち、請求項1に記載の発明によれば、シート形成物Aを形成後、シート形成物Aに形成した一つまたは複数の凹部に、そのまま、内容物を充填することができ、充填後、前記一つまたは複数の凹部を覆って配したシート形成物Bの上から、例えば、イージーピールオープンのシール条件でシール型を凹部の周囲に押しつけるだけで、容易に開封可能な凹部密封手段で密封することが可能であり、充填時の煩雑な開口作業も必要なく、充填後も、密封時の内容液の溢れ出しを防止するための煩雑な作業も必要がなくなる。
さらに、シート形成物Bの上から、例えば、通常のシール条件でシール型をシート形成物Aとシート形成物Bの周縁に押しつけるだけで、容易には開封できない周縁密封手段で密封することが可能であり、複数の凹部を包括して取り囲む一つの容器を形成することができる。
なお、シート形成物Bのシート形成物Aの凹部に対面する場所に、凹凸を設けて、充填時、滅菌時、保管時等における凹部空間の内圧変化を吸収するようにしても良い。
That is, according to the first aspect of the present invention, after forming the sheet formation A, one or a plurality of recesses formed in the sheet formation A can be directly filled with the contents. Sealed with a recess sealing means that can be easily opened from above the sheet formed product B arranged so as to cover the one or more recesses, for example, by simply pressing a seal mold around the recesses under easy peel-open sealing conditions. This eliminates the need for complicated opening work at the time of filling, and eliminates the need for troublesome work for preventing overflow of the content liquid at the time of sealing after filling.
Furthermore, from above the sheet formed product B, for example, it is possible to seal with a peripheral sealing means that cannot be easily opened by simply pressing the seal mold against the periphery of the sheet formed product A and the sheet formed product B under normal sealing conditions. It is possible to form a single container that encloses and surrounds a plurality of recesses.
It should be noted that unevenness may be provided at a location of the sheet formed product B facing the recess of the sheet formed product A so as to absorb changes in the internal pressure of the recessed space during filling, sterilization, storage, and the like.

ここで、凹部空間とは、シート形成物Aの凹部とシート形成物Bとがそれぞれの凹部において形成する空間をいう。
また、ここでいう凹部近傍とは、当該凹部の外側のみならず、当該凹部の周壁(内周面)の一部、例えば、内容物で満たされていない凹部の入り口付近の周壁をも含むことを意味している。
また、ここでいう易開封性密封手段とは、通常は密封されているが、使用者が開封する意志をもって開封する時、容易に開封できる密封手段であって、例えば、イージーピールオープン性を有するシール、または、シール際が薄肉に形成された破断し易いシール等が採用される。
Here, the recessed space means a space formed by the recessed portion of the sheet formed product A and the sheet formed product B in each recessed portion.
In addition, the vicinity of the concave portion here includes not only the outer side of the concave portion but also a part of the peripheral wall (inner peripheral surface) of the concave portion, for example, the peripheral wall near the entrance of the concave portion not filled with the contents. Means.
In addition, the easy-open sealing means here is normally a seal means that can be easily opened when the user opens with the will to open, and has, for example, easy peel open characteristics. For example, a seal or a seal that is thinly formed and easily breaks is used.

なお、易開封性密封手段の一部に、開封時にピールオープンも破断もしないで接合したままの部分があったとしても、開封時に、密封された内容物が密封された空間から外部に移し替え可能に密封状態が破壊されるのであれば、ここでいう易開封性密封手段にあたる。
例えば、開封操作時に親容器から、凹部に内容物を溶解または希釈するに足る十分な液が容易に流入し、かつ、内容物を流入した液と共に容易に排出できるかぎり、または、ピールオープンも破断もしないで接合したままの部分が易開封性密封手段の全周の半分以下の場合、ここでいう易開封性密封手段あたる。
Even if some of the easy-opening sealing means remain bonded without being peel-opened or broken at the time of opening, the sealed contents are transferred from the sealed space to the outside at the time of opening. If the sealed state is destroyed as much as possible, it corresponds to the easy-opening sealing means here.
For example, as long as a sufficient amount of liquid to dissolve or dilute the contents from the parent container into the recess can be easily flowed in and opened from the parent container, and the contents can be easily discharged together with the liquid that has flowed in, or the peel-open is broken. If the part that remains bonded is less than half of the entire circumference of the easy-open sealing means, this means the easy-open sealing means.

また、ここでいう難開封性密封手段とは、開封することを目的としない密封手段であり、通常のシール、例えば、通常の熱溶着がこれに当たる。
また、ここでいう連通可能な連結手段とは、機械的強度の繋がりだけでなく、容器内の流路等も繋がり、容器内の流体が容器間を移動できる状態を意味する。
また、ここでいう周縁密封手段とは、必ずしも、容器の周縁を全周に渡って密封している必要はなく、周縁の一部に他の機能を有する別の構成が設けられている場合には、その構成を除く周縁を密封する場合もこれに含まれる。
また、周縁密封手段は、必ずしも、難開封性密封手段のみで構成されるものではなく、例えば、周縁密封手段の一部を、将来、剥離開封するような場合には、その部分を易開封性密封手段で構成し、残りの部分を難開封性密封手段で構成することになる。
Further, the hard-to-open sealing means here is a sealing means not intended to be opened, and an ordinary seal, for example, ordinary heat welding, corresponds to this.
Moreover, the connection means which can be communicated here means not only the connection of mechanical strength but also the flow path in the container and the like, which means a state in which the fluid in the container can move between the containers.
In addition, the peripheral sealing means here does not necessarily need to seal the peripheral edge of the container over the entire periphery, and when another configuration having other functions is provided on a part of the peripheral edge. This includes the case of sealing the peripheral edge excluding the configuration.
Further, the peripheral sealing means is not necessarily constituted only by the difficult-to-open sealing means. For example, when a part of the peripheral sealing means is peeled and opened in the future, the part is easily opened. The sealing means is configured, and the remaining part is configured with a difficult-to-open sealing means.

また、ここでいう周縁密封手段上に設けられとは、周縁密封手段の一部に他の機能を有する別の構成が設けられている状態をいう。すなわち、他の機能を有する別の構成が設けられていない場合は周縁密封手段であるべきところに、他の機能を周縁密封手段の一部と置き換えて設けることを意味するものである。
また、ここでいう凹部密封手段の外側とは、必ずしも、凹部密封手段から離れた外側を意味するものではなく、周縁密封手段の一部が凹部密封手段の一部と接したり重なったりしていても、全体として、凹部密封手段の外側にあればこれに含まれる。
The term “provided on the peripheral sealing means” as used herein refers to a state in which another configuration having another function is provided in part of the peripheral sealing means. That is, when another configuration having other functions is not provided, this means that the other functions are replaced with a part of the peripheral sealing means where the peripheral sealing means should be provided.
Further, the outer side of the recess sealing means here does not necessarily mean the outer side away from the recess sealing means, and a part of the peripheral sealing means is in contact with or overlaps with a part of the recess sealing means. Is also included as a whole if it is outside the recess sealing means.

なお、ここでは、シート形成物Aとシート形成物Bが別部材のように記載しているが、シート形成物Aとシート形成物Bが同一のシートの一部であっても良い。例えば、一枚のシートの右半分に凹部を設けてこれをシート形成物Aとし、残りの半分をシート形成物Bとして中央から折り畳むことによって、シート形成物Aの凹部側を覆えば、本発明の製造方法になることは明らかである。
この場合、折り目の部分を別の方法でシールしないとすれば、折り目自体が、ここでいう周縁密封手段となる。
また、ここでいう接着するとは、二つのシート形成物を、単に、くっついている状態にすることを意味し、そのくっつきの程度または強度について意味を持たないものとした。
そして、くっつきの程度または強度につては、後文で説明するようにした。
Here, the sheet formed product A and the sheet formed product B are described as separate members, but the sheet formed product A and the sheet formed product B may be part of the same sheet. For example, if the concave portion of the sheet formed product A is covered from the center by providing a concave portion in the right half of one sheet and making this a sheet formed product A and the other half as a sheet formed product B, the present invention It is clear that the manufacturing method becomes.
In this case, if the fold portion is not sealed by another method, the fold itself becomes the peripheral sealing means here.
Further, the term “adhesion” as used herein means that the two sheet-formed products are simply brought into a state of sticking, and the degree or strength of the sticking is meaningless.
The degree or strength of sticking will be explained later.

なお、シート形成物Aまたはシート形成物Bは、単層または多層の樹脂層から成り、ここで使用される樹脂としては、例えば、ポリオレフィン系樹脂、ポリエステル系樹脂、ポリアクリロニトリル系樹脂、ポリアクリル系樹脂、ポリアミド系樹脂、塩化ビニル樹脂、塩素化ポリエチレン樹脂、塩化ビニリデン系樹脂、ポリビニルアルコール系樹脂、エチレン−酢酸ビニル共重合体、エチレン−アクリル共重合体、アイオノマー、環状ポリオレフィン樹脂、各種の熱可塑性エラストマー等の樹脂およびこれらの樹脂の混合物から選ばれるが、特に、ポリオレフィン系樹脂または環状ポリオレフィン系樹脂が好ましい。ポリオレフィン系樹脂としては、直鎖状低密度ポリエチレン樹脂、低密度ポリエチレン樹脂、高密度ポリエチレン樹脂、エチレン−酢酸ビニル共重合体、エチレン−アクリル共重合体、アイオノマー樹脂、ポリプロピレン樹脂、オレフィン系熱可塑性エラストマーおよびこれらの樹脂の混合物等が上げられる。また、環状ポリオレフィン系樹脂としては、COP樹脂、COC樹脂およびこれらの樹脂の混合物等が上げられる。  The sheet-formed product A or the sheet-formed product B is composed of a single layer or a multilayer resin layer. Examples of the resin used here include polyolefin resins, polyester resins, polyacrylonitrile resins, and polyacrylic resins. Resin, polyamide resin, vinyl chloride resin, chlorinated polyethylene resin, vinylidene chloride resin, polyvinyl alcohol resin, ethylene-vinyl acetate copolymer, ethylene-acrylic copolymer, ionomer, cyclic polyolefin resin, various thermoplastics Although selected from resins such as elastomers and mixtures of these resins, polyolefin resins or cyclic polyolefin resins are particularly preferred. Examples of polyolefin resins include linear low density polyethylene resins, low density polyethylene resins, high density polyethylene resins, ethylene-vinyl acetate copolymers, ethylene-acrylic copolymers, ionomer resins, polypropylene resins, and olefin thermoplastic elastomers. And a mixture of these resins. Examples of the cyclic polyolefin resin include COP resin, COC resin, and a mixture of these resins.

なお、これらの樹脂は、少なくとも、内容物の薬剤に、溶出物、薬剤成分の吸着、吸収等による影響等を与えない形態で使用される。特に、環状ポリオレフィン系樹脂は、各種の薬剤に対して、薬剤成分の吸着、吸収等による影響等を与えないので、薬液と接触する容器の内壁の素材として使用することが好ましい。
また、シート形成物Aとシート形成物Bの対面する双方の面に選定される樹脂としては、容易に開封可能なシールと、容易には開封できないシールの両方が可能な樹脂またはその組み合わせを選定するのが好ましい。
また、シート形成物Aは、射出成形、インフレーション成形、押し出し成形、ブロー成形、カレンダー成形、真空成形、圧空成形、ブロー成形等の成形方法、または、それらの組み合わせにより形成され、シート形成物Bは、射出成形、インフレーション成形、押し出し成形、ブロー成形、カレンダー成形等の成形方法により形成される。
These resins are used at least in a form that does not affect the contents of the drug due to adsorption, absorption, etc. of the eluate and drug components. In particular, since the cyclic polyolefin-based resin does not affect the various chemicals due to the adsorption and absorption of the drug component, etc., it is preferably used as a material for the inner wall of the container that comes into contact with the chemical solution.
In addition, as the resin selected for both the facing surfaces of the sheet formed product A and the sheet formed product B, a resin or a combination thereof capable of both a seal that can be easily opened and a seal that cannot be easily opened is selected. It is preferable to do this.
Further, the sheet formed product A is formed by a molding method such as injection molding, inflation molding, extrusion molding, blow molding, calendar molding, vacuum forming, pressure forming, blow molding, or a combination thereof, and the sheet formed product B is It is formed by a molding method such as injection molding, inflation molding, extrusion molding, blow molding or calendar molding.

また、請求項2に記載の発明は、請求項1に記載の構成に加え、シートを形成する工程の後に凹部を形成する工程を行うことを特徴とする。
すなわち、請求項2に記載の発明によれば、シート形成物Aは、インフレーション成形、押し出し成形、カレンダー成形等の成形方法によりシートまたはフィルムを形成した後で、真空成形、圧空成形等の成形方法により凹部を形成すれば良いので、シート形成物A及びその原反、並びに、シート形成物B及びその原反を、それぞれ1本の帯状にして搬送できるので、搬送が容易になり、充填・製袋設備が単純化でき、ひいては、トラブルの少ない、安価な設備で易開封型内容物入り複室容器を製造できる。
The invention described in claim 2 is characterized in that, in addition to the structure described in claim 1, a step of forming a recess is performed after the step of forming a sheet.
That is, according to the invention described in claim 2, after the sheet formed product A is formed into a sheet or film by a molding method such as inflation molding, extrusion molding or calendar molding, a molding method such as vacuum molding or pressure molding.
