【発明の属する技術分野】
本発明は、大量の液状又は流動性飲食品を、安価、且つ無菌的に移動することができるバッグ・イン・ボックスに関し、更に詳しくは、金属製コンテナーに代替可能な容量と取り扱い性を有し、また、金属製コンテナーに比べてより経済的に用いることができ、しかも、金属製コンテナーと同様に飲食品の充填・取出を無菌的に行うことができる、耐熱バルブ付バッグ・イン・ボックスに関する。
【０００２】
【従来の技術】
従来、食品用大型無菌充填容器として、ステンレススチール等の金属製コンテナー（以下、ハードコンテナーと略称する）が用いられている。しかし、ハードコンテナーは、▲１▼制作費が高いので初期投資費用が大きい、▲２▼使用量の変化に対応困難、▲３▼洗浄・保管等の保守管理のための広い場所及び費用が必要、▲４▼空容器返却費用が充填容器同様必要等の欠点がある。
【０００３】
一方、無菌充填用バッグ・イン・ボックス（以下、ＢＩＢと略称する）は、例えば、外装にダンボール、内装にプラスチックフィルムを使用した少量充填用のものが従来より使用されている。また、ＢＩＢの大型化も検討され使用されるようになってきているが、通常、大型ＢＩＢの場合、受入タンク等への配管が必要であって、その為、配管接続部での微生物汚染が問題になる。しかし、その内装バッグの充填・取出部材質がプラスチックであるので、充填・取出口を加熱殺菌するためには耐熱性や機械的強度に乏しい。その為、大型のＢＩＢは、無菌条件での製品の取り出しに対応が困難となり、例えば、微生物汚染の心配が無い飲食品製品等への使用に限定されているのが現状である。
【０００４】
【発明が解決しようとする課題】
特に大型ハードコンテナーの物理的、コスト的欠点が解決できるＢＩＢではあるが、上記のようにＢＩＢの充填・取出部にはプラスチック材質のものが取り付けられ、メーカーによりその充填口の仕様やサイズが異なるため、専用の充填機が必要となるなどの問題もある。しかし、ＢＩＢに関する最重要課題は、いかにして無菌的に飲食品製品を充填・取出可能にするか、特に、製品を取り出す際の取り出し口の殺菌処理対策をいかにするかであって、この対策こそ、充填された製品の微生物汚染防止の為に早急に解決されなければならない極めて重要な課題である。このことが解決されて初めて、コスト的にハードコンテナーよりも格段に有利であると言える。
【０００５】
【課題を解決するための手段】
そこで本発明者等は、上記課題を解決するため鋭意研究を行なってきた。その結果、ＢＩＢの内装バッグに取り付けられているプラスチック材質の充填・取出部に、金属製等の耐熱バルブを接続し、その後の容器滅菌、製品充填、移動、製品取出迄の全過程において、該耐熱バルブを接続したままで流通させることによって、製品取出時のバルブ蒸気殺菌が可能になり、微生物汚染が防止できるのみならず、充填時または取出時の移送容器との配管接続の適合性も向上することを見出し本発明を完成した。本発明により、ＢＩＢの欠点が改善され、ハードコンテナーよりコスト的に大いに有利になったと言える。以下に、本発明の具体的態様について説明する。
【０００６】
【発明の実施の形態】
本発明の例を図１に示した。プラスチックラミネートフィルム製の内装バッグ１に、プラスチック製の充填・取出口２が接着され、この充填・取出口２にサニタリー仕様のステンレススチールバルブ３がヘルール４を介して接続されている図である。
【０００７】
製品の充填前にバッグのガンマー線照射による滅菌処理が施され、製品の充填は、ヘルール６で取り付けられている閉止蓋７を取り除いて、受入側タンクからの配管を接続して行われる。その際、該配管の口径がバルブ３の口径と異なる場合は、レジューサーを挿入すればよい。充填終了時、コック５により弁を閉じ、バルブの外部側内面を洗浄した後閉止蓋７をヘルール６で取り付ける。
【０００８】
また、製品を取り出す時は、閉止蓋７を取り除いた後殺菌するため、蒸気をバルブ３の外部側内面に吹き込む。この際の高圧蒸気殺菌は、本発明のように耐熱バルブを接続することによって、はじめて可能になったものである。具体的には、予め殺菌された受入側タンク配管の端末バルブとＢＩＢ側の耐熱バルブが接続された状態にして接続部分を高圧蒸気殺菌し、殺菌後に受入側タンク配管の端末バルブ及びＢＩＢの耐熱バルブを開くことによって、微生物汚染の心配が全くなく製品を取り出すことができる。
【０００９】
なお、本発明のＢＩＢは、例えば、折り畳み可能なダンボール製や軽量スチール製枠などの外装ボックスの中に入れて充填、移動、取出を行った後、耐熱バルブは図１のヘルール４で取り外して上記の折り畳んだ外装ボックスとともに返却すればよい。内装バッグのみをワンウェイ容器として使用するので、経済効率を良くすることができる。
【００１０】
また、本発明で使用できるバルブは、例えば、１１０℃以上の耐熱性のものであれば樹脂製やカーボン製、或いは、セラミック製等のものでも使用可能であるが、好ましくは、経済的、衛生的、臭気的観点から金属製が良く、より好ましくは、サニタリー仕様のステンレススチール製のものを挙げることができる。
【００１１】
また、本発明の内装バッグは、接着されている充填・取出部が、充填・取出口を併用する１個のタイプのものでも、或いは、充填口と取出口が別個になっているタイプのものでも良い。プラスチックバッグの利点として、充填口は、充填後に密封できるので、充填口と取出口が別個になっているタイプの場合、取出口に耐熱バルブを接続しておけばよい。また、耐熱バルブの接続は、ヘルールを用いる他に、各種のサニタリー仕様の接続ができるものであれば同様に使用することができる。
【００１２】
【発明の効果】
本発明によって大量の液状又は流動性飲食品を、安価、且つ無菌的に移動することができるようになった。

BACKGROUND OF THE INVENTION
The present invention relates to a bag-in-box that can move a large amount of liquid or fluid food and drink at low cost and aseptically. More specifically, the present invention has a capacity and handleability that can replace metal containers. In addition, the present invention relates to a bag-in-box with a heat-resistant valve that can be used more economically than a metal container and can be aseptically filled and unloaded with food and drink as with a metal container. .
[0002]
[Prior art]
Conventionally, metal containers such as stainless steel (hereinafter abbreviated as hard containers) have been used as large aseptic filling containers for food. However, (1) the production cost is high, so the initial investment cost is large, (2) it is difficult to respond to changes in usage, and (3) it requires a large space and cost for maintenance management such as cleaning and storage. (4) There is a drawback that the empty container return cost is necessary as well as the filled container.
[0003]
On the other hand, as a bag-in-box for aseptic filling (hereinafter abbreviated as BIB), for example, a small-sized filling bag using cardboard for the exterior and a plastic film for the interior has been used. In addition, BIBs are becoming larger and are now being used, but normally, large BIBs require piping to the receiving tank, etc., so that there is microbial contamination at the pipe connection. It becomes a problem. However, since the filling / unloading member material of the interior bag is plastic, heat resistance and mechanical strength are poor in order to heat sterilize the filling / unloading port. For this reason, large-sized BIBs are difficult to handle when taking out products under aseptic conditions, and are currently limited to use for food and drink products that are free from microbial contamination.
[0004]
[Problems to be solved by the invention]
Although BIB can solve the physical and cost disadvantages of large hard containers in particular, plastic material is attached to the BIB filling / unloading section as described above, and the specifications and size of the filling port differ depending on the manufacturer. Therefore, there is a problem that a dedicated filling machine is required. However, the most important issue regarding BIB is how to make it possible to aseptically fill and take out food and drink products, and in particular how to take measures against sterilization of the outlet when taking out the products. This is a very important issue that must be solved immediately to prevent microbial contamination of the filled product. Only when this is solved can it be said that it is much more advantageous than hard containers in terms of cost.
[0005]
[Means for Solving the Problems]
Therefore, the present inventors have conducted intensive research to solve the above problems. As a result, a heat-resistant valve made of metal or the like is connected to the plastic material filling / unloading part attached to the BIB interior bag, and in the subsequent processes from container sterilization, product filling, transfer, and product removal, By distributing the heat-resistant valve while connected, it becomes possible to sterilize the valve steam when taking out the product, not only prevent microbial contamination, but also improve the compatibility of the piping connection with the transfer container at the time of filling or taking out. As a result, the present invention has been completed. It can be said that the present invention has improved the disadvantages of the BIB and has greatly improved the cost over the hard container. Specific embodiments of the present invention will be described below.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
An example of the present invention is shown in FIG. FIG. 2 is a view in which a plastic filling / extraction port 2 is bonded to an interior bag 1 made of a plastic laminate film, and a sanitary
[0007]
Before the product is filled, the bag is sterilized by gamma ray irradiation, and the product is filled by removing the closing lid 7 attached by the ferrule 6 and connecting the piping from the receiving side tank. At that time, if the diameter of the pipe is different from the diameter of the
[0008]
When the product is taken out, steam is blown into the inner surface on the outer side of the
[0009]
Note that the BIB of the present invention is placed in an outer box such as a foldable corrugated cardboard or lightweight steel frame, and after filling, moving, and taking out, the heat-resistant valve is removed by the ferrule 4 in FIG. What is necessary is just to return with the above-mentioned folded exterior box. Since only the interior bag is used as a one-way container, economic efficiency can be improved.
[0010]
In addition, the valve that can be used in the present invention can be made of resin, carbon, ceramic, or the like as long as it has a heat resistance of 110 ° C. or higher. From the standpoint of odor and odor, it is preferably made of metal, and more preferably, sanitary specification stainless steel.
[0011]
In addition, the interior bag of the present invention may be of a single type in which the filling / removal part bonded is a combination of the filling / removal part, or the filling / removal part is a separate type. But it ’s okay. As an advantage of the plastic bag, since the filling port can be sealed after filling, in the case of a type in which the filling port and the outlet are separated, a heat-resistant valve may be connected to the outlet. Further, the heat resistant valve can be connected in the same manner as long as it can be connected to various sanitary specifications in addition to using a ferrule.
[0012]
【The invention's effect】
According to the present invention, a large amount of liquid or fluid food and drink can be moved at low cost and aseptically.
