Description

本発明は、液体を詰めた包装体に関し、特に過酸化水素を含む液体を詰めた包装体に関する。   The present invention relates to a package packed with a liquid, and particularly to a package packed with a liquid containing hydrogen peroxide.

従来から、液体及びその液体を詰めた容器からなる包装体では、種々の形態が提案されている。例えば、２剤型染毛剤第二剤は、過酸化水素その他の薬剤が溶け込んだ水溶液であるが、プラスチック製成型容器に詰めて販売されている。２剤型染毛剤第二剤が入っている従来のプラスチック製成型容器は、２剤型染毛剤第二剤を漏らさないために液密性を要求される。   Conventionally, various forms have been proposed for a package including a liquid and a container filled with the liquid. For example, the two-component hair dye second agent is an aqueous solution in which hydrogen peroxide and other chemicals are dissolved, but is sold in a plastic molded container. The conventional plastic molded container containing the two-component hair dye second agent is required to have liquid-tightness so as not to leak the second agent hair dye second agent.

２剤型染毛剤第二剤中の過酸化水素は、安定化の処理がなされていることから、２０℃前後の温度では比較的安定化しているものの、酸素を発生しつつ徐々に分解する。   Since the hydrogen peroxide in the second agent type hair dye second agent is stabilized, it is relatively stabilized at a temperature around 20 ° C., but gradually decomposes while generating oxygen. .

従来の包装体は、過酸化水素等の化学物質を含む液体を備えており、さらに化学物質及び液体を入れるためのプラスチック製成型容器を備えている。液密性を有するプラスチック製成型容器は、同時に気密性も有していることから、過酸化水素が発生する酸素など、化学物質が発生するガスによって膨張するという問題を抱えている。   A conventional package includes a liquid containing a chemical substance such as hydrogen peroxide, and further includes a plastic molded container for containing the chemical substance and the liquid. Since the plastic molded container having liquid tightness is also airtight at the same time, it has a problem that it is expanded by a gas generated by a chemical substance such as oxygen generated by hydrogen peroxide.

また、過酸化水素等の化学物質が化学反応によって変化するため、内容物に占める当該化学物質の含有率が減少するという問題も生じる。

JP 2001-10642 A JP-T-2001-511416 Japanese Patent Application No. 2001-321031 (Japanese Patent Laid-Open No. 2003-116632) JP 2000-2260336 A

本発明は、このような従来の構成が有していた問題を解決しようとするものであり、過酸化水素を含む２剤型染毛剤第二剤が詰められている容器からなる包装体の膨張を抑制するとともに、２剤型染毛剤第二剤中の過酸化水素の含有率を安定化させることを目的とする。   The present invention is intended to solve the problems of such a conventional configuration, and is a package comprising a container packed with a two-component hair dye second agent containing hydrogen peroxide. It aims at stabilizing the content rate of hydrogen peroxide in the two-component hair dye second agent while suppressing swelling.

課題を解決するための手段および発明の効果Means for Solving the Problems and Effects of the Invention

そして、本発明は上記目的を達成するために、第１の課題解決手段として、水に対する過酸化水素の含有率がｙである２剤型染毛剤第二剤をフィルムよりなる容器内に充填して包装体を製造するに当たり、前記フィルムとして、包装体中における過酸化水素の分解により発生する単位時間当りの酸素発生量より大きい酸素透過率が得られるとともに、単位時間当たりの過酸化水素の分解する質量ｘを前記含有率ｙで除した質量ｚの水が単位時間当たりに蒸発するとした場合の値にほぼ等しい水蒸気透過率が得られるものを使用した、包装体の製造方法を提供するものである。
ここで「水に対する過酸化水素の含有率」は過酸化水素の質量を水の質量で除した値である。 In order to achieve the above object, the present invention fills a container made of a film with a two-component hair dye second agent having a hydrogen peroxide content ratio of y to water as a first problem solving means. In producing the package, the film has an oxygen transmission rate larger than the amount of oxygen generated per unit time generated by the decomposition of hydrogen peroxide in the package, and the hydrogen peroxide per unit time. Provided is a method for producing a packaging body using a material having a water vapor transmission rate substantially equal to a value obtained when water of mass z obtained by dividing mass x to be decomposed by content y is evaporated per unit time. It is.
Here, the “content ratio of hydrogen peroxide to water” is a value obtained by dividing the mass of hydrogen peroxide by the mass of water.

第２の課題解決手段は、第１の課題解決手段において、フィルムとして、該フィルムから製作した容量１００ｍｌ、内面積０．０２３ｍ２の容器に２剤型染毛剤第二剤を充填した場合に、保管温度４０℃の環境下での酸素透過率が８ｃｃ／１８０日、水蒸気透過率が２．５〜４．５ｇ／１８０日となるものを使用するものである。 The second problem-solving means is the case where, in the first problem-solving means, as a film, a two-component hair dye second agent is filled in a container having a capacity of 100 ml and an inner area of 0.023 m 2 manufactured from the film. The one having an oxygen permeability of 8 cc / 180 days and a water vapor permeability of 2.5 to 4.5 g / 180 days in an environment at a storage temperature of 40 ° C. is used.

第３の課題解決手段は、第１の課題解決手段において、フィルムとして、該フィルムから製作した容量１０００ｍｌ、内面積０．０６８ｍ２の容器に２剤型染毛剤第二剤を充填した場合に、保管温度４０℃の環境下での酸素透過率が３００〜５００ｃｃ／１８０日、水蒸気透過率が２５〜４５ｇ／１８０日となるものを使用するものである。 The third problem-solving means is the case where, in the first problem-solving means, as a film, a container having a capacity of 1000 ml and an inner area of 0.068 m 2 manufactured from the film is filled with the second agent type hair dye second agent. The one having an oxygen permeability of 300 to 500 cc / 180 days and a water vapor permeability of 25 to 45 g / 180 days in an environment at a storage temperature of 40 ° C. is used.

第４の課題解決手段は、第１の課題解決手段において、フィルムとして、該フィルムから製作した容量５００ｍｌ、内面積０．０４６ｍ２の容器に２剤型染毛剤第二剤を充填した場合に、保管温度４０℃の環境下での酸素透過率が１５０〜２５０ｃｃ／１８０日、水蒸気透過率が１２．５〜２２．５ｇ／１８０日となるものを使用するものである。 The fourth problem-solving means is the case where, in the first problem-solving means, as a film, a two-component hair dye second agent is filled in a container having a capacity of 500 ml and an inner area of 0.046 m 2 manufactured from the film. The one having an oxygen permeability of 150 to 250 cc / 180 days and a water vapor permeability of 12.5 to 22.5 g / 180 days in an environment at a storage temperature of 40 ° C. is used.

第５の課題解決手段は、第１から第４の課題解決手段のいずれかの方法によって製造された包装体である。   The fifth problem solving means is a package manufactured by any one of the first to fourth problem solving means.

第１から第５の課題解決手段による作用効果は次のとおりである。すなわち、過酸化水素が分解して酸素が発生しても、発生した酸素を、フィルムを透過させて包装体外部に逃がすことができ、包装体内部に酸素を充満させない。また、過酸化水素の分解に伴って、２剤型染毛剤第二剤中の過酸化水素の質量が減少する。水は、包装体内が飽和蒸気圧に達していれば蒸発が進まないので、フィルムが透過する水蒸気量に応じて水の量を減じられる。フィルムを透過する水蒸気量を過酸化水素の質量変化に則して選定することにより水と過酸化水素の比をほぼ一定に保つことができる。   The effects of the first to fifth problem solving means are as follows. That is, even if hydrogen peroxide is decomposed and oxygen is generated, the generated oxygen can pass through the film and escape to the outside of the package, and the package is not filled with oxygen. Further, as the hydrogen peroxide is decomposed, the mass of hydrogen peroxide in the two-component hair dye second agent decreases. Since the water does not evaporate if the inside of the package has reached the saturated vapor pressure, the amount of water can be reduced according to the amount of water vapor that the film permeates. By selecting the amount of water vapor that passes through the film in accordance with the change in mass of hydrogen peroxide, the ratio of water to hydrogen peroxide can be kept substantially constant.

過酸化水素が分解して減少する質量をｘグラムとすると、質量ｘを過酸化水素の含有率ｙで除した値x／ｙが、過酸化水素が分解しても過酸化水素水の濃度を一定に保つために、単位時間当たりに取り除かなければならない水の質量ｚに相当する。水蒸気透過率は、この水の質量ｚが単位時間当りに蒸発するとした場合の値にほぼ等しく、従って余分な水を除去して過酸化水素水の濃度を安定に保てる。   Assuming that the mass that hydrogen peroxide decomposes and decreases is x grams, the value x / y obtained by dividing the mass x by the hydrogen peroxide content y is the concentration of the hydrogen peroxide solution even when hydrogen peroxide is decomposed. Corresponds to the mass z of water that must be removed per unit time to keep it constant. The water vapor transmission rate is substantially equal to the value when the mass z of water evaporates per unit time, and therefore, excess water is removed and the concentration of the hydrogen peroxide solution can be kept stable.

また、第２ないし第４の課題解決手段によれば、同手段に係る選定条件を満たすフィルムを使用して容器を製作することにより、保管温度１５℃から３０℃で６ヶ月を越える長期間保管する場合における過酸化水素の濃度を安定化できる。   In addition, according to the second to fourth problem solving means, a container is manufactured using a film that satisfies the selection condition according to the means, thereby allowing a storage temperature of 15 ° C. to 30 ° C. for a long period of time exceeding 6 months. In this case, the concentration of hydrogen peroxide can be stabilized.

以下、本発明の第１実施形態に係る包装体を図１に基づいて説明する。
図１は、本発明の第１実施形態に係る包装体の外観を示す斜視図である。
図１の包装体１は、プラスチックフィルム製の容器本体２、コネクタ３及び２剤型染毛剤第二剤（図示省略）を備えてなる。
プラスチックフィルム製容器本体２は、４枚のプラスチック製フィルムによって構成されている。正面側部の第１フィルム２ａに対応して背面側部の第２フィルム（図示省略）が配置され、第１及び第２フィルムは相互に上下縁部がヒートシールされてシール線４ａが上下位置に形成されている。
第３及び第４フィルムが各々半分に織り込まれた状態で、シール線４ａの端部の各々に、第３及び第４フィルムの各々の上下端部が挟み込まれている。
第１フィルム２ａと第２フィルムの横縁部は、襠をつくるために、第３フィルム２ｂ及び第４フィルム（図示省略）の横縁部にヒートシールされてシール線４ｂが形成される。
図２は、２剤型染毛剤第二剤の入っていない空の状態のプラスチックフィルム製容器を示す平面図及び正面図である。
図２に示すようにフィルム２ｂにより形成される襠が折り込まれた状態においては、フィルム数枚分まで薄くできる。そのため２剤型染毛剤第二剤を充填する前の空の状態について比較すると、従来のプラスチック製成型容器に比べ、プラスチックフィルム製容器本体２の占有体積を少なくでき、輸送し保管する際のコストを削減することができる。また、廃棄する際にも廃棄物の容積を減少させることができる。 Hereinafter, the packaging body which concerns on 1st Embodiment of this invention is demonstrated based on FIG.
FIG. 1 is a perspective view showing an appearance of a package according to the first embodiment of the present invention.
The package 1 in FIG. 1 includes a plastic film container body 2, a connector 3, and a two-component hair dye second agent (not shown).
The plastic film container body 2 is composed of four plastic films. A second film (not shown) on the back side is disposed corresponding to the first film 2a on the front side, and the first and second films are heat-sealed at the upper and lower edges so that the seal line 4a is in the vertical position. Is formed.
With the third and fourth films woven in half, the upper and lower ends of each of the third and fourth films are sandwiched between the ends of the seal wire 4a.
The lateral edges of the first film 2a and the second film are heat-sealed to the lateral edges of the third film 2b and the fourth film (not shown) to form a crease, thereby forming a seal line 4b.
FIG. 2 is a plan view and a front view showing an empty plastic film container that does not contain a two-component hair dye second agent.
As shown in FIG. 2, in the state in which the ridge formed by the film 2b is folded, the film can be thinned up to several films. Therefore, comparing the empty state before filling with the two-component hair dye second agent, the occupied volume of the plastic film container body 2 can be reduced as compared with the conventional plastic molded container, and it can be transported and stored. The cost can be reduced. In addition, the volume of waste can be reduced during disposal.

図２に示すプラスチックフィルム製容器本体２に取り付けられているコネクタ３は、液密に再閉栓可能に構成されている。
コネクタ３は、例えば、正面側部の第１のフィルム２a（図２の紙面表側）と第２フィルム（図２の紙面裏側）とのヒートシールの際に、形成される上部シール線４ａの略中央部に取り付けられる。コネクタ３の取り付けは、第１フィルム２ａと第２フィルムとの間にコネクタ３を挟みこんだ状態でヒートシールすることにより行われる。 The connector 3 attached to the plastic film container main body 2 shown in FIG. 2 is configured so as to be capable of re-sealing in a liquid-tight manner.
For example, the connector 3 is an abbreviation of the upper seal line 4a formed at the time of heat sealing between the first film 2a (front side of the drawing in FIG. 2) on the front side and the second film (back side of the drawing in FIG. 2). Installed in the center. The connector 3 is attached by heat sealing in a state where the connector 3 is sandwiched between the first film 2a and the second film.

次に、コネクタ３の構成を図３及び図４に基づいて説明する。コネクタ３には、プラスチックフィルム製容器２内に詰められた２剤型染毛剤第二剤を出し入れするための貫通孔３ａが設けられている。また、コネクタ３には、プラスチックフィルム製容器本体２の内部側にキャップ３ｂが配設される。キャップ３ｂには、図４に示すように嵌合部３ｃが設けられ、図３に示すように嵌合部３ｃが貫通孔３ａに嵌合されることにより、プラスチックフィルム製容器本体２が液密に密封される。   Next, the structure of the connector 3 is demonstrated based on FIG.3 and FIG.4. The connector 3 is provided with a through-hole 3a for taking in and out the two-component hair dye second agent packed in the plastic film container 2. The connector 3 is provided with a cap 3b on the inner side of the plastic film container body 2. As shown in FIG. 4, the cap 3b is provided with a fitting portion 3c, and the fitting portion 3c is fitted into the through hole 3a as shown in FIG. Sealed.

次に、プラスチックフィルム製容器本体２を構成しているフィルムについて説明する。
第１から第４フィルムには同じ材質のものを用いてもよく、異なる材質のものとしてもよい。
１５℃から３０℃の条件で、数重量％から１０重量％の濃度の過酸化水素水を保管するのに適しているのは、例えば、厚さ数μｍから二十μｍのポリエチレンテレフタレートフィルム、厚さ数μｍから二十μｍのナイロンフィルム及び厚さ数十μｍから二百μｍのポリエチレンフィルムを容器の外側から内側に順に積層してなる積層フィルムである。
プラスチックフィルム製容器本体２の第１から第４フィルムのいずれかに上記のフィルムが含まれるか、又は全てを上記フィルムで構成してもよいが、上記フィルムは５００ｍｌから１０００ｍｌ程度の比較的大型の容器に適している。
また、上記フィルム構成においてさらに、ポリエチレンテレフタレートフィルムに酸化アルミニウムまたは酸化シリコンを蒸着した酸化アルミニウム層（アルミナ蒸着層）または酸化シリコン層（シリカ蒸着層）を備えてもよい。このフィルムを用いてプラスチックフィルム製容器本体２を構成する場合には、ガスバリア性が向上しており、１００ｍｌ程度の比較的小型の容器に適している。
また、プラスチックフィルム製容器本体２の第１から第４フィルムのいずれかに、厚さ数から二十μｍのポリエチレンテレフタレートフィルム、厚さ十から三十μｍのエチレンビニルアルコール共重合樹脂フィルム及び厚さ数十から二百μｍのポリエチレンフィルムを容器の外側から内側に順に積層してなる積層フィルムを用いてもよい。 Next, the film which comprises the plastic film container main body 2 is demonstrated.
The first to fourth films may be made of the same material or different materials.
For example, a polyethylene terephthalate film having a thickness of several μm to 20 μm is suitable for storing a hydrogen peroxide solution having a concentration of several to 10% by weight under conditions of 15 ° C. to 30 ° C. It is a laminated film obtained by laminating a nylon film having a thickness of several μm to 20 μm and a polyethylene film having a thickness of several tens μm to 200 μm in order from the outside to the inside of the container.
Any of the first to fourth films of the plastic film container body 2 may include the above-mentioned film, or all of the film may be composed of the above-mentioned film, but the film is a relatively large size of about 500 ml to 1000 ml. Suitable for containers.
Moreover, in the said film structure, you may provide the aluminum oxide layer (alumina vapor deposition layer) or the silicon oxide layer (silica vapor deposition layer) which vapor-deposited aluminum oxide or silicon oxide on the polyethylene terephthalate film. When the plastic film container body 2 is formed using this film, the gas barrier property is improved, and it is suitable for a relatively small container of about 100 ml.
Further, a polyethylene terephthalate film having a thickness of 20 μm, an ethylene vinyl alcohol copolymer resin film having a thickness of 10 to 30 μm, and a thickness are provided on any of the first to fourth films of the container body 2 made of plastic film. A laminated film obtained by laminating several tens to two hundred μm polyethylene films in order from the outside to the inside of the container may be used.

美容室などの室内において、１５℃から３０℃の温度条件で保管する場合、次のことが実験的に確かめられている。即ち、６重量％の過酸化水素濃度の２剤型染毛剤第二剤を容量１００ｍｌ、内面積０．０２３ｍ２のプラスチックフィルム製容器本体２に入れたとき、保管温度４０℃の環境下での容器１個当たりの酸素透過率が８ｃｃ／１８０ｄａｙ、水蒸気透過率が２．５から４．５グラム／１８０ｄａｙに設定することにより、保管温度１５℃から３０℃で６ヶ月を越える長期保管において過酸化水素の濃度を安定化できることが確かめられている。
例えば、酸化アルミニウム層（アルミナ蒸着層）が蒸着された厚さ１２μｍのポリエチレンテレフタレートフィルム、厚さ１５μｍのナイロンフィルム及び厚さ１００μｍのポリエチレンフィルムを容器の外側から内側に順に積層してなる積層フィルム（以下アルミナ蒸着フィルムという）を２枚重ね合わせ、ポリエチレンフィルム同士をヒートシールして９０ｍｍ×１３０ｍｍのアルミナ蒸着フィルム製容器を製作し、６重量％の過酸化水素濃度を有する２剤型染毛剤第二剤を充填したものを製造した。アルミナ蒸着層は、ポリエチレンテレフタレートフィルムとナイロンフィルムの間に配置される。 The following has been experimentally confirmed when storing in a room such as a beauty salon under a temperature condition of 15 ° C. to 30 ° C. That is, when a 2 agent type hair dye second agent having a hydrogen peroxide concentration of 6% by weight is placed in a plastic film container main body 2 having a capacity of 100 ml and an inner area of 0.023 m 2 , in an environment where the storage temperature is 40 ° C. By setting the oxygen transmission rate per container of 8 cc / 180 day and the water vapor transmission rate from 2.5 to 4.5 g / 180 day, the storage temperature is 15 ° C. to 30 ° C. and long-term storage exceeding 6 months. It has been confirmed that the concentration of hydrogen oxide can be stabilized.
For example, a laminated film in which an aluminum oxide layer (alumina vapor deposition layer) is deposited and a polyethylene terephthalate film having a thickness of 12 μm, a nylon film having a thickness of 15 μm, and a polyethylene film having a thickness of 100 μm are laminated in order from the outside to the inside of the container. (Hereinafter referred to as “alumina vapor-deposited film”), a polyethylene film is heat-sealed to produce a 90 mm × 130 mm alumina vapor-deposited container, and a two-component hair dye having a hydrogen peroxide concentration of 6% by weight. A product filled with two agents was produced. The alumina vapor deposition layer is disposed between the polyethylene terephthalate film and the nylon film.

上述のアルミナ蒸着フィルム製容器において、温度４０℃（相対湿度１０％程度）の乾燥機の中に入れて、６ヶ月間保管した後の過酸化水素濃度は、クリーム状の２剤型染毛剤第二剤について平均値で０．０６重量％濃度が薄まった。つまり、６重量％から５．９４重量％へ変化した。また、液状の２剤型染毛剤第二剤について平均値で０．２０重量％濃度が薄まった。
上述のアルミナ蒸着フィルム製容器を１５℃から３０℃の室内に保管した後、過酸化水素濃度は、クリーム状の２剤型染毛剤第二剤について平均値で０．０３重量％濃度が濃くなった。つまり、６重量％から６．０３重量％へ変化した。また、液状の２剤型染毛剤第二剤について平均値で０．０９重量％濃度が薄くなった。 In the above-mentioned container made of an alumina vapor-deposited film, the hydrogen peroxide concentration after being stored in a drier at a temperature of 40 ° C. (relative humidity of about 10%) for 6 months is a creamy two-component hair dye. The average concentration of the second agent was 0.06% by weight. That is, it changed from 6% by weight to 5.94% by weight. Moreover, the 0.20 weight% density | concentration became thin by the average value about the liquid 2 agent type hair dye 2nd agent.
After storing the above-mentioned alumina vapor-deposited film container in a room at 15 ° C. to 30 ° C., the hydrogen peroxide concentration is 0.03% by weight on average for the creamy two-component hair dye second agent. became. That is, it changed from 6% by weight to 6.03% by weight. Further, the 0.09% by weight concentration of the liquid two-component hair dye second agent became thin on average.

一方、市販されているポリエチレン製ブロー成型容器（容量１リットル）に、上述のクリーム状の２剤型染毛剤第二剤を充填して上述の乾燥機の中で４０℃の条件で６ヶ月保管した後の過酸化水素濃度は、平均値で０．３１重量％濃度が薄くなった。また、液状の２剤型染毛剤第二剤について平均値で０．４２重量％濃度が薄くなった。   On the other hand, a commercially available polyethylene blow-molded container (capacity 1 liter) is filled with the above-mentioned creamy two-component hair dye second agent, and in the above-mentioned dryer at 40 ° C. for 6 months. The average hydrogen peroxide concentration after storage decreased by 0.31% by weight. In addition, the average concentration of 0.42% by weight of the liquid two-component hair dye second agent became thin.

なお、厚さ１２μｍのポリエチレンテレフタレートフィルム、厚さ１５μｍのナイロンフィルム及び厚さ１２０μｍのポリエチレンフィルムを容器の外側から内側に順に積層してなる積層フィルムでプラスチックフィルム製容器本体２を構成した。そのような積層フィルムからなるプラスチックフィルム製容器本体２の容量が１０００ｍｌ、内面積が０．０６８ｍ２である場合に、保管温度４０℃の環境下での容器１個当たりの酸素透過率が３００から５００ｃｃ／１８０ｄａｙ、水蒸気透過率が２５から４５グラム／１８０ｄａｙに設定することにより、保管温度１５℃から３０℃で６ヶ月を越える長期間保管する場合における過酸化水素の濃度を安定化できることが確かめられている。 The plastic film container body 2 was composed of a laminated film obtained by laminating a polyethylene terephthalate film having a thickness of 12 μm, a nylon film having a thickness of 15 μm, and a polyethylene film having a thickness of 120 μm in order from the outside to the inside of the container. When the capacity of the plastic film container body 2 made of such a laminated film is 1000 ml and the inner area is 0.068 m 2 , the oxygen transmission rate per container in an environment at a storage temperature of 40 ° C. is from 300. By setting 500 cc / 180 day and water vapor transmission rate from 25 to 45 grams / 180 day, it is confirmed that the concentration of hydrogen peroxide can be stabilized when stored at a storage temperature of 15 ° C. to 30 ° C. for more than 6 months. ing.

また、プラスチックフィルム製容器本体２の容量が５００ｍｌ、内面積が０．０４６ｍ２である場合に、保管温度４０℃の環境下での容器１個当たりの酸素透過率が１５０から２５０ｃｃ／１８０ｄａｙ、水蒸気透過率が１２．５から２２．５グラム／１８０ｄａｙに設定することにより、保管温度１５℃から３０℃で６ヶ月を越える長期間保管する場合における過酸化水素の濃度を安定化できることが確かめられている。 Further, when the capacity of the plastic film container body 2 is 500 ml and the inner area is 0.046 m 2 , the oxygen transmission rate per container in an environment at a storage temperature of 40 ° C. is 150 to 250 cc / 180 day, water vapor It has been confirmed that by setting the transmittance to 12.5 to 22.5 grams / 180 days, the concentration of hydrogen peroxide can be stabilized when stored at a storage temperature of 15 ° C. to 30 ° C. for more than 6 months. Yes.

プラスチックフィルム製容器本体２の全体としての酸素透過率を、過酸化水素が分解して生じる単位時間あたりの酸素発生量と同程度か少し大きな値に設定してもよく、上述のように、単位時間あたりの酸素発生量に比べ、酸素透過率を十分大きく設定してもよく、プラスチックフィルム製容器本体２の膨張を防止することができる。   The oxygen permeability of the plastic film container body 2 as a whole may be set to a value that is the same as or slightly larger than the amount of oxygen generated per unit time generated by the decomposition of hydrogen peroxide. Compared to the amount of oxygen generated per hour, the oxygen permeability may be set sufficiently large, and the expansion of the plastic film container body 2 can be prevented.
