１０は、ガス非透過性包装材を用いて平面視が矩形に形成された２次包装袋である。この２次包装袋１０には液体収納袋５が収納され、さらに脱酸素剤１１と酸素検知剤１２とが入れられた状態で周縁部がヒートシールにて密閉される。脱酸素剤１１として、たとえば大江化学工業株式会社製タモツ（登録商標）が用いられる。酸素検知剤１２としては、たとえば三菱ガス化学株式会社製の錠剤エージレスアイ（登録商標）が用いられる。   Reference numeral 10 denotes a secondary packaging bag formed in a rectangular shape in plan view using a gas-impermeable packaging material. In this secondary packaging bag 10, the liquid storage bag 5 is stored, and the peripheral portion is sealed with a heat seal in a state where the oxygen scavenger 11 and the oxygen detector 12 are put. As the oxygen scavenger 11, for example, Tamotsu (registered trademark) manufactured by Oe Chemical Industry Co., Ltd. is used. As the oxygen detector 12, for example, Tablet Ageless Eye (registered trademark) manufactured by Mitsubishi Gas Chemical Co., Ltd. is used.

２次包装袋１０に用いられるガス非透過性包装材として、たとえばエチレンビニルアルコール共重合体（ＥＶＯＨ）、ポリエチレンテレフタレート（ＰＥＴ）ポリ塩化ビニリデン（ＰＶＤＣ）、ナイロンなどから構成された包装材、そしてこれらの素材にシリカやアルミナなどのガスバリア性物質の蒸着処理を行なった包装材、また、これらの素材を組み合わせた多層フィルムから作製された包装材などが用いられる。   Examples of gas-impermeable packaging materials used for the secondary packaging bag 10 include packaging materials composed of, for example, ethylene vinyl alcohol copolymer (EVOH), polyethylene terephthalate (PET), polyvinylidene chloride (PVDC), nylon, and the like. A packaging material in which a gas barrier material such as silica or alumina is vapor-deposited on the above material, or a packaging material made from a multilayer film combining these materials is used.

液体収納袋５は、隔壁６部分で折り曲げられて２つの袋部７ａ，７ｂが起立した２つ折りの状態で、かつ前記抽出口９が上方に向くように、２次包装袋１０に密閉状態で収納される。２次包装袋１０はガス非透過性包装材を用いて形成されており、この２次包装袋１０の内部には脱酸素剤１１が収納されているので、２次包装袋１０を密閉しておくことにより、その内部は脱酸素状態とされる。これによって、Ａ液とＢ液とが充填されている液体収納袋５の内部に酸素が浸入することを防止することができる。   The liquid storage bag 5 is folded in the partition wall 6 portion so that the two bag portions 7a and 7b are erected in a folded state, and the secondary packaging bag 10 is sealed so that the extraction port 9 faces upward. Stored. The secondary packaging bag 10 is formed using a gas-impermeable packaging material. Since the oxygen scavenger 11 is housed inside the secondary packaging bag 10, the secondary packaging bag 10 is sealed. By setting it, the inside is deoxidized. Accordingly, it is possible to prevent oxygen from entering the liquid storage bag 5 filled with the liquid A and the liquid B.

液体収納袋５は、隔壁６部分で折り曲げられて２つの袋部７ａ，７ｂが起立した状態で２次収納袋１０に収納されて保護されている。２次包装袋１０が破損して、外部から２次包装袋１０の内部に空気中の酸素が浸入すると、酸素検知剤１２がピンク色から紫色に変化することによって、２次包装袋１０の内部に酸素が浸入したことを容易に知ることができる。   The liquid storage bag 5 is stored in the secondary storage bag 10 and protected in a state in which the two bag portions 7a and 7b stand up while being bent at the partition wall 6 portion. When the secondary packaging bag 10 is damaged and oxygen in the air enters the inside of the secondary packaging bag 10 from the outside, the oxygen detecting agent 12 changes from pink to purple, whereby the inside of the secondary packaging bag 10 It is possible to easily know that oxygen has intruded.

２次包装袋１０に収納された液体収納袋５は、複数個まとめて大袋１３に収納され、この大袋１３が包装箱１に収納される。大袋１３は、たとえばポリエチレン、ポリ塩化ビニル（ＰＶＣ）などの２次包装袋１０より摩擦係数が低いフィルムを用いて形成される。このように液体収納袋５が複数個まとめて入れられた大袋１３の上端は密閉しない状態としておく。   A plurality of liquid storage bags 5 stored in the secondary packaging bag 10 are stored together in a large bag 13, and the large bag 13 is stored in the packaging box 1. The large bag 13 is formed using a film having a lower friction coefficient than that of the secondary packaging bag 10 such as polyethylene or polyvinyl chloride (PVC). In this way, the upper end of the large bag 13 in which a plurality of liquid storage bags 5 are put together is not sealed.

包装箱１は図示の如く、複両面段ボール板を用いて形成されているのが強度上好ましく、両面段ボール板を用いて包装箱１を形成した場合に比して包装箱１の強度を向上させることができ、液体収納袋５を外からの衝撃に対して保護することができる。   As shown in the drawing, the packaging box 1 is preferably formed using a double-sided corrugated cardboard in terms of strength, and the strength of the packaging box 1 is improved as compared with the case where the packaging box 1 is formed using a double-sided cardboard board.

In the packaging structure in which a plurality of liquid storage bags 5 are stored, the liquid storage bag 5 is folded in the partition 6 portion and is folded in two in which the two bag portions 7a and 7b are erected. A plurality of liquid storage bags 5 individually stored in a sealed state in a secondary packaging bag 10 which is formed by using an oxygen scavenger and is stored in the secondary packaging bag 10 in a sealed state. Since it is stored in the packaging box 1 in a state where it is stored in the large bag 13 having a lower coefficient of friction than the secondary packaging bag 10, the secondary packaging bag 10 is sealed and the inside is deoxygenated, and the interior of the liquid storage bag 5 Can prevent oxygen in the air from entering Furthermore, the liquid storage bag 5 in which two kinds of infusion solutions are individually stored in the two bag portions 7a and 7b partitioned by the partition wall 6 is folded, and the two bag portions 7a and 7b stand up. In the case of storing in a state, it is possible to prevent the partition wall 6 from being damaged and the two types of infusions from being inadvertently mixed or from leaking out to the outside.

また、包装箱１の底部には緩衝シート１４が載置されており、液体収納袋５は緩衝シート１４に載置された状態で包装箱１に収納されるので、液体収納袋５が包装箱１の外部から受ける衝撃を緩和して、折り曲げられた隔壁６部分が剥離するのを効果的に防止することができる。特に包装箱１の底板を形成する底板形成用フラップ３ｂと３ｂとの段差に隔壁６部分が当たって傷付くことを緩衝シート１４によって防止することができる。   In addition, a buffer sheet 14 is placed on the bottom of the packaging box 1, and the liquid storage bag 5 is stored in the packaging box 1 while being placed on the buffer sheet 14. It is possible to relieve the impact received from the outside of 1 and effectively prevent the folded partition wall 6 from peeling off. In particular, the buffer sheet 14 can prevent the partition 6 from hitting the step between the bottom plate forming flaps 3b and 3b forming the bottom plate of the packaging box 1 and being damaged.

さらに、包装箱１は複両面段ボール板を用いて形成されることにより、両面段ボール板を用いて包装箱１を形成した場合に比して変形しにくく、包装箱１の強度を向上させることができ、液体収納袋５を効果的に保護することができる。   Furthermore, the packaging box 1 is formed using a double-sided cardboard board, so that it is less likely to be deformed than when the packaging box 1 is formed using a double-sided cardboard board, and the strength of the packaging box 1 can be improved. The liquid storage bag 5 can be effectively protected.
