【発明の詳細な説明】
（産業上の利用分野）
本発明は、バッグ・イン・ボックスとして知られている
容器内に収納させているプラスチック容器内に内容物を
充填する際、折り畳み状態にあるプラスチック容器を膨
らませる方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a plastic container which is folded when filled with contents in a container known as a bag-in-box. Concerning how to inflate plastic containers.
（従来の技術及び解決すべき課題）
従来より段ボール箱等の外箱内にプラスチック類の内容
器を収容した容器は、バッグ・イン・ボックスと称され
、軽便性、及び経済性にすぐれているため酒類、液体肥
料等をはじめとして各種の液体収納容器として広く使用
されている。(Prior art and problems to be solved) Containers that have traditionally housed a plastic inner container inside an outer box such as a cardboard box are called bag-in-boxes, and are lightweight and economical. Therefore, it is widely used as a storage container for various liquids, including alcoholic beverages and liquid fertilizers.
このようなバッグ・イン・ボックスに使用されるプラス
チック容器（以下、この容器を単に内容器という）は、
ダイスより所定の合成樹脂をそれぞれシート状または筒
状に溶融押昌した後、直ちに、容器の対角面で接合でき
るような形状を有するモールドを使用して真空成形若し
くは吹き込み成形手段により容器の半部体を成形し、し
かる後、これらを接合して製造されている（特公昭４５
−３９９５７号公報参照）。The plastic container used for such bag-in-boxes (hereinafter referred to simply as the inner container) is
Immediately after melting and extruding the specified synthetic resin into a sheet or cylinder shape using a die, the container halves are formed by vacuum forming or blow molding using a mold that has a shape that allows the diagonal surfaces of the container to be joined. It is manufactured by molding the parts and then joining them together (Special Publication Act, 1977).
(Refer to Publication No. 39957).
そして、この内容器は、使用前は輸送効率や取扱性等の
ため折畳み状態、すなわち、一方の容器半部体を他方の
容器半部体内に重ねるように、折り込み挿入した状態と
している。したがって、内容器に内容物を充填するに際
し、従来は前述の折畳まれた内容器内に空気を送入して
容器を膨らませ、しかる後、内容物を充填していたが、
この方法では空気送入後瞬時に容器の折り畳みが膨らま
させられるため、折り傷が発生し、この部分より充填し
た内容液が漏出することが生じた。Before use, the inner container is in a folded state for transport efficiency, ease of handling, etc., that is, one container half is folded and inserted into the other container half so that it is stacked on top of the other. Therefore, when filling the inner container with the contents, conventionally, air was introduced into the folded inner container to inflate the container, and then the contents were filled.
In this method, the folded container is inflated instantly after air is introduced, resulting in creases that cause the filled liquid to leak out from these parts.
そこで、この空気送入方法を改善する方法として、例え
ば、送入する空気圧を小さくして時間をかけて膨らませ
る方法、或いは、膨らませたとき傷を発生しないプラス
チックによって内容器を製造する方法等が提案されてい
る。Therefore, as ways to improve this air feeding method, for example, there is a method to reduce the air pressure to be fed and inflate it over time, or a method to manufacture the inner container from plastic that does not cause scratches when inflated. Proposed.
しかし、折り傷が発生しないように空気圧を小さくして
長時間を掛けて徐々に膨らませる方法は、充填に時間が
かかり、コストアップする結果となり好ましくなく、ま
た、材料を変更する方法にあっては傷を発生しないプラ
スチックとしてゴム状弾性を有する材料が使用されるが
、この材料は容器としての形状保持性が乏しい。However, the method of gradually inflating over a long period of time by lowering the air pressure to avoid creases is undesirable as it takes time to fill and increases costs. A material with rubber-like elasticity is used as a plastic that does not cause scratches, but this material has poor shape retention as a container.
そこで、本発明者は、上記の欠点を改良すべく種々検討
した結果、本発明を完成したもので、本発明の目的は、
内容器に何等の損傷を生じることなく短時間のうちに内
容器を膨らませる方法を提供するにある。Therefore, the present inventor has completed the present invention as a result of various studies to improve the above-mentioned drawbacks.The purpose of the present invention is to:
To provide a method for inflating an inner container in a short time without causing any damage to the inner container.

スチック容器を膨らませる方法である。(Means for Solving the Problems) That is, the gist of the present invention is to provide a method for pre-inflating a plastic container in a folded state when filling the container with contents. This method of inflating plastic containers is characterized by blowing hot air into the container.
すなわち、本発明は内容器内に４０℃〜７０℃の熱風を
