Description

本件発明は、酸素検知剤の製造方法、及びその方法を用いて製造される酸素検知剤に関し、具体的には、還元糖と塩基と酸化還元色素とを用いた酸素検知剤の製造方法、及びその方法を用いて製造される酸素検知剤に関する。   The present invention relates to a method for producing an oxygen detector, and an oxygen detector produced using the method, specifically, a method for producing an oxygen detector using a reducing sugar, a base, and a redox dye, and The present invention relates to an oxygen detector produced by using the method.

一般的に、食品や医薬品等は、空気中の酸素により酸化して品質が劣化する。また、最近では、食品等を入れた包装体内に異物混入の事件等も度々起こり、問題となっている。そのため、多くの食品や医薬品等は、酸素の進入を検知するための酸素検知剤と共に包装体内に入れられて密封されるようになっている。この酸素検知剤は、酸化還元色素とそれに対する還元剤とを含む組成物からなり、酸化還元色素としてメチレンブルーが多く用いられている。ここで、酸化還元色素としてメチレンブルーを用いた場合に、酸素検知剤は、酸素がない場合には無色を呈し、酸素が有る場合には青色を呈する。なお、この酸素検知剤に関しては、従来より所定の大きさ及び形状に打錠成形された錠剤タイプのものが主に用いられている。   In general, foods, pharmaceuticals, and the like are deteriorated in quality by being oxidized by oxygen in the air. In recent years, incidents of contamination of foreign matter frequently occur in a package containing food or the like. For this reason, many foods, pharmaceuticals, and the like are placed in a package and sealed together with an oxygen detection agent for detecting the entry of oxygen. This oxygen detector is composed of a composition containing a redox dye and a reducing agent for the redox dye, and methylene blue is often used as the redox dye. Here, when methylene blue is used as the oxidation-reduction dye, the oxygen detecting agent is colorless when there is no oxygen, and blue when there is oxygen. As for the oxygen detector, a tablet type tableted into a predetermined size and shape has been mainly used.

ところが、酸素検知剤として錠剤タイプを用いた場合には、この錠剤タイプの酸素検知剤を個包装する必要がある等製造工程が複雑であるため製造コストがかかる上、小型化を図ることが困難である。また、消費者より、色の変化のみならず文字等によっても酸素の有無を検知出来るようにして欲しいとの要望が強く、錠剤タイプの酸素検知剤ではこの要望に応えることが難しかった。このように、従来より製造コストの低減、小型化及び酸素検知の容易化を図ることの出来る酸素検知剤の提供が求められていた。   However, when a tablet type is used as the oxygen detection agent, the manufacturing process is complicated, such as the need to individually wrap the oxygen detection agent of this tablet type, and the manufacturing cost is high and it is difficult to reduce the size. It is. In addition, there is a strong demand from consumers to be able to detect the presence or absence of oxygen not only by color change but also by letters, etc., and it has been difficult to meet this demand with tablet-type oxygen detection agents. As described above, it has been demanded to provide an oxygen detector that can reduce the manufacturing cost, reduce the size, and facilitate the oxygen detection.

例えば、特許文献1には、包装体内の酸素の存在を発色という手段を用いて検知すべく、酸化還元色素、揮発性還元剤、不揮発性還元剤、アルカリ物質、バインダー、溶媒からなるインク組成物に基づき製造したインクをインクジェットプリンタに用い、紙やフィルムに塗布して酸素検知剤を製造する方法が開示されている(引用文献1の請求項1、段落0033等参照のこと。)。   For example, Patent Document 1 discloses an ink composition comprising a redox dye, a volatile reducing agent, a non-volatile reducing agent, an alkaline substance, a binder, and a solvent in order to detect the presence of oxygen in the package by means of color development. A method for producing an oxygen detecting agent by applying the ink produced based on the above to an ink jet printer and applying it to paper or a film is disclosed (see claim 1, paragraph 0033, etc. of cited document 1).

また、特許文献2には、少なくとも酸化還元色素であるメチレンブルーと、還元剤であるD−グルコースと、酸価が50〜300mgKOH/gであるとともにガラス転移点が10〜70℃であるアクリル系共重合体とからなることを特徴とする酸素インジケーター組成物を印刷により酸素検知基材上に形成して酸素検知剤を製造する方法が開示されている(引用文献2の請求項1,3等参照のこと。)。   Patent Document 2 discloses at least methylene blue as a redox dye, D-glucose as a reducing agent, and an acrylic copolymer having an acid value of 50 to 300 mgKOH / g and a glass transition point of 10 to 70 ° C. A method for producing an oxygen detector by forming an oxygen indicator composition comprising a polymer on an oxygen detection substrate by printing is disclosed (see claims 1 and 3 of cited reference 2, etc.). Of that.)

以上の引用文献に開示されている方法により製造される酸素検知剤は、コスト面や生産性に優れ、小型化を実現可能であり、また、文字等によって酸素の有無を容易に検知することが可能となる。   The oxygen detector produced by the method disclosed in the above cited document is excellent in cost and productivity, can be downsized, and can easily detect the presence or absence of oxygen by letters or the like. It becomes possible.

以下、本件発明に係る酸素検知剤の製造方法、及びその方法を用いて製造される酸素検知剤の一実施形態について説明する。   Hereinafter, an embodiment of an oxygen detection agent manufacturing method according to the present invention and an oxygen detection agent manufactured using the method will be described.

本件発明に係る酸素検知剤の製造方法: 本件発明に係る酸素検知剤の製造方法は、還元糖と塩基と酸化還元色素とを用いた酸素検知剤の製造方法であって、還元糖と塩基とを含むアルカリ溶液を酸素検知基材における発色領域に塗布し乾燥させた後に、酸化還元色素を含む色素溶液を当該発色領域に塗布するものであり、当該アルカリ溶液及び当該色素溶液の少なくとも一方に、純水とグリセリンとアルコールと乳化剤とを含ませ、当該アルカリ溶液及び当該色素溶液の少なくとも一方を、インクジェット方式により当該酸素検知基材における発色領域に吐出することを特徴とする。 Manufacturing method of oxygen detector according to the present invention: The manufacturing method of the oxygen detecting agent according to the present invention is a method of manufacturing an oxygen detector using a reducing sugar, a base, and a redox dye, wherein the reducing sugar, the base, Is applied to the color development region of the oxygen detection substrate and dried, and then a dye solution containing a redox dye is applied to the color development region, and at least one of the alkali solution and the dye solution, Pure water, glycerin, alcohol, and an emulsifier are included, and at least one of the alkaline solution and the dye solution is discharged to a color development region of the oxygen detection substrate by an ink jet method.

本件発明に係る酸素検知剤の製造方法は、還元糖と塩基と酸化還元色素とを用いた酸素検知剤の製造方法に関し、酸素検知剤製造用インクを還元糖と塩基とを含むアルカリ溶液と、酸化還元色素を含む色素溶液とに分けて用いることで、酸素検知剤製造用インクにおける沈殿物の発生を抑制し、酸化検知剤製造用インクの長期使用が可能となる。また、本件発明に係る酸素検知剤の製造方法のように、アルカリ溶液を酸素検知基材における発色領域に塗布し乾燥させた後に、色素溶液を当該発色領域の上に重ねて塗布することで、酸素検知剤の色付きを濃くすると共に、発色反応を速くすることが出来る。更に、また、本件発明に係る酸素検知剤の製造方法によれば、プリントされた直後の文字等の滲みやしみの発生を抑制し、且つ酸素検知後の色むらの発生を抑制することも出来る。   The method for producing an oxygen detector according to the present invention relates to a method for producing an oxygen detector using a reducing sugar, a base, and a redox dye, an oxygen solution for producing the oxygen detecting agent, an alkaline solution containing a reducing sugar and a base, By separately using the dye solution containing the oxidation-reduction dye, the generation of precipitates in the ink for producing the oxygen detection agent is suppressed, and the ink for producing the oxidation detection agent can be used for a long time. In addition, as in the method for producing an oxygen detector according to the present invention, after applying and drying an alkaline solution on the color development region in the oxygen detection substrate, the dye solution is applied over the color development region, In addition to darkening the color of the oxygen detector, the color development reaction can be accelerated. Furthermore, according to the method for producing an oxygen detector according to the present invention, it is possible to suppress the occurrence of bleeding and blotting of characters immediately after printing, and to suppress the occurrence of color unevenness after oxygen detection. .

ちなみに、本件発明に係る酸素検知剤の製造方法において、酸素検知基材に対して上述のアルカリ溶液を塗布するにあたっては、インクジェットプリンタを用いて塗布する他、別容器に溜めた当該アルカリ溶液の中に浸積させて塗布したり、霧吹き等を用いて塗布することも可能である。ここで、酸素検知基材に対して当該アルカリ溶液を塗布するにあたり、インクジェットプリンタを用いた場合には、酸素検知剤を製造する上で必要な発色領域のみにアルカリ溶液を塗布することが出来るため、当該アルカリ溶液の消費量を抑え、製造コストを効果的に削減させることが出来る。   By the way, in the method for producing an oxygen detector according to the present invention, when applying the above-mentioned alkaline solution to the oxygen detection substrate, in addition to the application using an ink jet printer, the alkaline solution stored in a separate container It is also possible to apply it by immersing it in a mist, or to apply it using a sprayer or the like. Here, in applying the alkaline solution to the oxygen detection substrate, when an ink jet printer is used, the alkaline solution can be applied only to a color development region necessary for producing the oxygen detection agent. The consumption of the alkaline solution can be suppressed, and the manufacturing cost can be effectively reduced.

そして、塗布した上述のアルカリ溶液が乾燥した後に、酸素検知基材に対して上述の色素溶液を塗布するにあたっては、インクジェットプリンタを用いて、当該アルカリ溶液を塗布した領域の上に当該色素溶液を吐出させることで、文字等によっても酸素の有無を検知出来るようになる。このように、本件発明に係る酸素検知剤の製造方法によれば、酸素検知基材の材質にもある程度左右されるものの、上述した方法により当該アルカリ溶液と当該色素溶液とをこの順に塗布することで、従来のように酸素検知剤製造用インクに含める酸化還元色素の量を多くしなくとも、十分に発色を濃くすることが可能となり、酸化還元色素が沈殿するのを抑制することが出来る。   And after apply | coating the above-mentioned alkaline solution dried, in apply | coating the said dye solution with respect to an oxygen detection base material, the said dye solution is applied on the area | region which applied the said alkali solution using an inkjet printer. By discharging, the presence / absence of oxygen can be detected by letters or the like. Thus, according to the method for producing an oxygen detector according to the present invention, the alkali solution and the dye solution are applied in this order by the method described above, although it depends to some extent on the material of the oxygen detection substrate. Therefore, it is possible to sufficiently darken the color without increasing the amount of the redox dye included in the ink for producing the oxygen detecting agent as in the prior art, and the precipitation of the redox dye can be suppressed.

なお、本件発明に係る酸素検知剤の製造方法において、酸化還元色素としてメチレンブルー等を好適に用いることが出来る。また、アルコールとして、エチルアルコール等を好適に用いることが出来る。また、乳化剤として、グリセリン脂肪酸等を好適に用いることが出来る。ちなみに、酸化還元色素としてメチレンブルーを用いた場合には、発色が青色となる。   In the method for producing an oxygen detector according to the present invention, methylene blue or the like can be suitably used as the redox dye. Moreover, ethyl alcohol etc. can be used suitably as alcohol. Moreover, a glycerol fatty acid etc. can be used suitably as an emulsifier. Incidentally, when methylene blue is used as the redox dye, the color is blue.

ここで、本件発明に係る酸素検知剤の製造方法は、上述のアルカリ溶液に純水とグリセリンとアルコールと乳化剤とを含ませ、且つ、上述の色素溶液にアルコールを含ませることが好ましい。   Here, in the method for producing an oxygen detector according to the present invention, it is preferable that pure water, glycerin, alcohol, and an emulsifier are included in the alkaline solution, and alcohol is included in the dye solution.

上述したように、本件発明に係る酸素検知剤の製造方法は、還元糖と塩基とを含むアルカリ溶液と、酸化還元色素(メチレンブルー等)を含む色素溶液とを分けて用いることが前提条件としてある。この条件を満たす限りにおいては、当該アルカリ溶液に対して純水とグリセリンとアルコール(エチルアルコール等)と乳化剤(グリセリン脂肪酸等)とを含め、且つ、当該色素溶液に対してアルコール(エチルアルコール等)を含めることも好ましい。当該色素溶液にアルコール(エチルアルコール等)を含めることで、当該色素溶液中において沈殿物の生成が抑制され、長期間安定してインクジェットプリンタを稼働させて酸素検知剤の製造を行うことが出来る。   As described above, the method for producing an oxygen detector according to the present invention is premised on the separate use of an alkaline solution containing a reducing sugar and a base and a dye solution containing a redox dye (such as methylene blue). . As long as this condition is satisfied, pure water, glycerin, alcohol (such as ethyl alcohol) and emulsifier (such as glycerin fatty acid) are included in the alkaline solution, and alcohol (such as ethyl alcohol) in the dye solution. It is also preferable to include. By including alcohol (ethyl alcohol or the like) in the dye solution, the formation of precipitates in the dye solution is suppressed, and the oxygen detector can be manufactured by operating the ink jet printer stably for a long period of time.

Therefore, the presence or absence of oxygen can be confirmed quickly and easily.
