〔産業上の利用分野〕
本発明は雰囲気中の酸素の有無を色変化により指示する
酸素インジケーターに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an oxygen indicator that indicates the presence or absence of oxygen in the atmosphere by color change.
酸素インジケーターは真空包装法、窒素シール法、脱酸
素剤法等、物品の無酸素保存方法と併用することにより
、容器内の酸素の有無を確認でき、ひいては、脱気の不
完全、または容器の密閉不良による空気漏れ＊（７））
ラブルを発見するのに有用なものである。Oxygen indicators can be used in conjunction with oxygen-free storage methods such as vacuum packaging, nitrogen sealing, and oxygen scavenger methods to confirm the presence or absence of oxygen in the container. Air leakage due to poor sealing *(7))
This is useful for discovering troubles.
本発明は、酸素インジケーター組成物固形状物が包装袋
に収・納されてなる酸素インジケーターに関するもので
ある。The present invention relates to an oxygen indicator in which a solid oxygen indicator composition is housed in a packaging bag.
通常、酸素インジケーター組成物は取り扱いあるいは流
通上の簡便さを考慮して固形状態に調製されており、ま
た、共存物品と直接接触してもそれを汚染しないよう透
明プラスチックフィルムで包装されている。Oxygen indicator compositions are usually prepared in a solid state for ease of handling and distribution, and are packaged in a transparent plastic film so as not to contaminate coexisting products even if they come into direct contact with them.
したがって、酸素インジケーター組成物を収納している
フィルム袋、内の雰囲気と検知対象となるその外部雰囲
気とが実質的に遮断されるため、従来は、フィルムの一
部を切り開くかまたは針穴を穿って通気性付与して実用
に供してきた。Therefore, because the atmosphere inside the film bag containing the oxygen indicator composition and the atmosphere outside of it to be detected are substantially cut off, it has conventionally been necessary to cut a portion of the film or punch a needle hole. It has been put into practical use by imparting air permeability.
しかしながら、この方法によれば開口部分の大きさの調
節が自由ではなかった。However, according to this method, the size of the opening cannot be freely adjusted.
上記したように酸素インジケーターの袋内雲囲気と外部
検知対象雰囲気とを通気性付与させる際に従来のごとく
酸素インジケーターフィルム袋の一部を切り開いたり針
穴を穿ったりしたものは次のような問題点があった。As mentioned above, the following problems occur when a part of the oxygen indicator film bag is cut open or a needle hole is punched as in the past when providing ventilation between the cloud surrounding the oxygen indicator bag and the external detection target atmosphere. There was a point.
（１）切り開いた部分もしくは針穴を穿った部分を通し
て酸素インジケーター組成物が漏れ出し、検知対象の外
部雰囲気に共存する物品を汚染したりする。(1) The oxygen indicator composition leaks out through the cut-out or needle hole, contaminating articles coexisting in the external atmosphere to be detected.
（２）酸素インジケーター組成物の性能は通常、該組成
物中に含まれる微量水分により正常機能を保持するもの
であるが、共存物品が高い平衡湿度をもつ場合該組成物
は湿分を吸収して水分過多による異常を度々発生する。(2) The performance of the oxygen indicator composition is normally maintained by trace amounts of moisture contained in the composition, but if the coexisting articles have high equilibrium humidity, the composition may absorb moisture. Abnormalities often occur due to excessive moisture.
例えば、ペースト化による性能不発揮が生ずる。For example, poor performance may occur due to pasting.
（３）上記とは逆に、乾煙状態にある物と共存した場合
、該組成物に必須の＠量水分が乾怪物に移行するので、
水分不足による性能不発揮をみることもある。(3) Contrary to the above, if the composition coexists with something in a dry smoke state, the essential water content of the composition will be transferred to the dry smoke.
Performance may be impaired due to lack of moisture.
本発明者らはかかる問題点を克服すべく鋭意検討した結
果、共存物品と接触してもそれを汚染することかなく、
検知対象となる外部雰囲気と酸素インジケーター組成物
封入袋内雰囲気とが自在にコントロールされた必要かつ
充分な通気性を付与された酸素インジケーターを開発し
、本発明を完成するに至った。The inventors of the present invention have made extensive studies to overcome these problems, and have found that even if they come into contact with coexisting products, they will not be contaminated.
The present invention has been completed by developing an oxygen indicator that has the necessary and sufficient air permeability in which the external atmosphere to be detected and the atmosphere within the bag containing the oxygen indicator composition are freely controlled.
すなわち本発明は、透明部分を有する収納部と接合部と
を有する袋に酸素インジケーター組成物固形状物が密封
包装されてなる酸素インジケーターにおいて、鉄製の接
合部が少なくともその一個所で少なくとも１本の糸また
は糸状物を配して接合されてなり、鉄系または糸状物の
一部は鉄製の収納部に存在し、かつその一部が鉄製の外
部に達していることを特徴とする酸素インジケーターを
提供するするものである。That is, the present invention provides an oxygen indicator in which a solid oxygen indicator composition is hermetically packaged in a bag having a storage part having a transparent part and a joint part, in which the iron joint part has at least one iron joint part. The oxygen indicator is made by arranging and joining threads or thread-like materials, and a part of the iron-based or thread-like materials is present in the iron storage part, and a part of it reaches the outside of the iron. This is what we offer.
本発明において酸素インジケーターとは雰囲気中の酸素
