523 Publication). In this method, a small amount of hydrogen peroxide is present in a polyethylene terephthalate resin container, the mouth of the container is sealed with a lid or sealant, and the inside of the container is sterilized by sterilization with hydrogen peroxide. After this container is supplied to an aseptic filling machine and only the outer surface of the container is sterilized, the lid material etc. are removed and the contents are filled into the container to produce an aseptically filled product.

物中に溶出して（るという問題点がある。However, in the above-mentioned method of feeding a container filled with hydrogen peroxide to an aseptic filling machine, most of the hydrogen peroxide sealed in the container for sterilization (decomposes naturally and disappears); There is a problem in that some hydrogen peroxide remains in the container in a state in which it is adsorbed to the resin layer forming the container, and is eluted into the contents after the contents are filled.

テレフタレート樹脂で形成されたことを特徴とする。The present invention provides a container in which a hydrogen peroxide solution is sealed and sterilized inside the container, which is made of polyethylene terephthalate resin synthesized through a polycondensation process using an antimony-based polycondensation catalyst. It is characterized by

る。A container is formed from polyethylene terephthalate resin using an antimony-based polycondensation catalyst. When the container thus formed is sterilized with hydrogen peroxide, it is possible to prevent or minimize the amount of hydrogen peroxide remaining in the container.
以下に、１．５１の炭酸飲料用ペットボトルに本発明を
適用した具体例を、従来例との比較において説明する。A specific example in which the present invention is applied to a 1.51 carbonated beverage PET bottle will be described below in comparison with a conventional example.

て従来品に係る試料Ａを得た。Sample A, which is a conventional product, was obtained by forming a 1.51 PET bottle using a polyethylene terephthalate resin synthesized using a germanium-based polycondensation catalyst (G e O2) in a conventionally known polycondensation process.

発明に係る試料Ｂを得た。In addition, a 1.51 PET bottle was formed from a polyethylene terephthalate resin synthesized using an antimony-based polycondensation catalyst (Sb203) in the same polycondensation process as described above to obtain Sample B according to the present invention.
次いで、試料ＡおよびＢのそれぞれのペットボトル内に
濃度５％の過酸化水素水溶液２０μｌを封入し、温度２
２℃の条件下で２日間保管した。Next, 20 μl of a hydrogen peroxide aqueous solution with a concentration of 5% was sealed in each PET bottle of samples A and B, and the temperature was 2.
It was stored for 2 days at 2°C.
尚、過酸化水素水溶液の封入は、第１図に示すようにボ
トル１内にノズル３で所定量の過酸化水素水溶液を滴下
する。その後、ボトル１の口をキャップ２で締めて密封
することにより行なう（第２図）。The aqueous hydrogen peroxide solution is sealed by dropping a predetermined amount of the aqueous hydrogen peroxide solution into the bottle 1 using a nozzle 3, as shown in FIG. Thereafter, the bottle 1 is sealed by tightening the mouth of the bottle 1 with the cap 2 (FIG. 2).
そして、上記のようにして保管した試料ＡおよびＢの各
ボトル内にイオン交換水５０ｍＪを入れ、再び密封し、
よく震った後、２２℃で保管する。Then, 50 mJ of ion-exchanged water was poured into each of the bottles of samples A and B stored as described above, and the bottles were sealed again.
After shaking well, store at 22℃.
そして、一定時間経過後に、各ボトルについてイオン交
換水中の過酸化水素濃度を酸素電極法により測定した。After a certain period of time had passed, the concentration of hydrogen peroxide in the ion-exchanged water for each bottle was measured using an oxygen electrode method.
この結果を、次頁の表１に示す。なお、測定値がイオン

下することが確認された。(Unit: ppm) In this way, when the polyethylene terephthalate resin used to form PET bottles is synthesized using an antimony-based polycondensation catalyst, the excess excess is lower than when it is synthesized using a germanium-based polycondensation catalyst. It was confirmed that the residual amount of hydrogen oxide was significantly reduced.

溶液の封入及び保管を行った。Furthermore, after 104 Bacillus subtilis spores were attached to the inner surface of each of the bottles of Samples A and B, an aqueous hydrogen peroxide solution was sealed and stored in the same manner as above.

できた。After storage for a predetermined period, trypto soy broth was injected into each bottle of Samples A and B, and cultured at 37°C to confirm the presence of viable bacteria. No bacteria were found. In other words, even if the polyethylene terephthalate resin that forms PET bottles is synthesized using an antimony-based polycondensation catalyst, the bactericidal effect of hydrogen peroxide is still the same as when it is synthesized using a germanium-based polycondensation catalyst. It was confirmed that this was obtained, and that there were no practical problems.
尚、本発明は食品用の包装容器に限定されるものではな

より安価で製造することができる等の効果を奏する。As described above, in the present invention, since the container is formed of polyethylene terephthalate resin synthesized through a polycondensation process using an antimony-based polycondensation catalyst, hydrogen peroxide is sealed inside the container and the inside of the container is sterilized. When filling the contents after applying sterilization, this method simplifies the process inside the aseptic filling machine and simplifies and downsizes the aseptic filling machine itself, while also removing hydrogen peroxide and preventing it from remaining inside the container. This can prevent elution into the contents. Furthermore, the polyethylene terephthalate resin can be synthesized at a lower cost than using a germanium-based polycondensation catalyst.
