Description

化学発光体Chemiluminescent material
　本発明は、化学発光用の化学組成物を用いた化学発光体に関する。 The present invention relates to a chemiluminescent material using a chemiluminescent chemical composition.
　従来、コンサートライトのようにイベント時に用いられるライトや防災用ライト等の手持ち型ライト、夜間の釣り用に使用される浮き、セレモニー会場の装飾等のように、化学発光用蛍光液と化学発光用酸化液の組み合わせのような２種類の液体や固体を混合させることで化学発光を生じさせる化学発光体が広く用いられている。これらの化学発光体には種々の形状があるが、代表的なものとしては、筒状のコンサートライトがあり、これは、化学発光用の蛍光液を含む外部ケース内に、化学発光用の酸化液を充填したガラスアンプルの内部ケースを設けた構成が一般的である。そして、保管時においては酸化液と蛍光液がガラスアンプルによって分離されるものの、使用時には化学発光体を折り曲げることでガラスアンプルが破割し、２種の液が混合し筒状容器内で化学発光が生じる構成とされている。 Conventionally, chemiluminescent fluorescent liquids and chemiluminescent lamps, such as handheld lights such as concert lights used at events and disaster prevention lights, floats used for night fishing, and decoration of ceremony venues. Chemiluminescent substances that generate chemiluminescence by mixing two types of liquids and solids, such as a combination of oxidizing liquids, are widely used. These chemiluminescent materials come in a variety of shapes, but a typical one is a tubular concert light, which is oxidized for chemiluminescence in an outer case containing a fluorescent solution for chemiluminescence. Generally, an inner case of a glass ampoule filled with a liquid is provided. The oxide liquid and the fluorescent liquid are separated by a glass ampoule during storage, but the glass ampoule is broken by bending the chemiluminescent material during use, and the two types of liquid are mixed and chemiluminescent in a tubular container. Is configured to occur.
　このような化学発光を利用するものとして、特許文献１には偏平状化学発光具が開示されている。これは、薄い平面状で、柔軟性があり、液漏れを生じない偏平状化学発光具を提供するものであり、例えばワッペン状玩具なとどして用いられるものである。また、特許文献２には、ざ瘡の化学発光治療に用いられるマスク等が開示されている。これは、特定の波長の光が、ざ瘡の治療に有用であるという知見に基づき、その治療に有効な波長の光をマスク状等のフレキシブル容器内で化学発光により生じさせ、そのマスクを取り付けることで皮膚症状（ざ瘡）の治療を行うものである。 Patent Document 1 discloses a flat chemiluminescent tool as a device that utilizes such chemiluminescence. This provides a flat chemiluminescent device that is thin, flat, flexible, and does not leak, and is used, for example, as an emblem-shaped toy. Further, Patent Document 2 discloses a mask and the like used for chemiluminescent treatment of acne. This is based on the finding that light of a specific wavelength is useful for the treatment of pimples, and light of a wavelength effective for the treatment is generated by chemiluminescence in a flexible container such as a mask, and the mask is attached. This is a treatment for skin symptoms (pimples).
　一方、化学発光体は、一般的には、蛍光液と、酸化液との混合性を高めるために、いずれも流動性が高い低粘性の液状とすることが多いが、固体等を用いても良く、例えば、特許文献３には、高い粘性を有する組成物を用いた印付けシステムおよびそのメカニズムを利用した収容デバイスが開示されている。 On the other hand, the chemiluminescent material is generally a low-viscosity liquid having high fluidity in order to improve the mixing property of the fluorescent liquid and the oxidizing liquid, but a solid or the like may also be used. At best, for example, Patent Document 3 discloses a marking system using a highly viscous composition and a containment device utilizing the mechanism thereof.
　特許文献４は、高粘度化学組成物を保持した多孔性シートを配置した外袋を有する偏平状発光体を開示するものであり、内袋を保護する内袋保護シートを有する偏平状発光体なども開示している。 Patent Document 4 discloses a flat illuminant having an outer bag on which a porous sheet holding a high-viscosity chemical composition is arranged, such as a flat illuminant having an inner bag protective sheet for protecting the inner bag. Is also disclosed.

　化学発光体として、その形状の自由度を高めるために、フィルムやシートを用いて薄く成形した外袋を用いることが考えられる。しかし、発光体の内部に蛍光液と酸化液の分離に汎用されているガラスアンプルを用いると、破割されたガラスアンプルによって薄い外袋は破れてしまうおそれがあり危険である。このために、特許文献１、２では内袋（中袋）に、軟質でフィルム状のＰＥやＰＰ、プラスチックパッケージを利用することが提案されている。 As a chemiluminescent material, it is conceivable to use an outer bag that is thinly molded using a film or sheet in order to increase the degree of freedom in its shape. However, if a glass ampoule that is widely used for separating a fluorescent liquid and an oxidizing liquid is used inside the light emitter, the thin outer bag may be torn by the broken glass ampoule, which is dangerous. For this reason, Patent Documents 1 and 2 propose to use a soft, film-like PE, PP, or plastic package for the inner bag (middle bag).
　一方、液以外を用いた化学発光組成物として、特許文献３が開示されているが、これは、あくまで地面や紙等に、化学発光組成物を用いた文字や図形等のマーキング（印付け）をするために、容器から吐出した化学発光組成物が高粘性を示すように調製されたものであり、容器内において高粘度の化学発光組成物を利用しようとするものではなかった。 On the other hand, Patent Document 3 is disclosed as a chemiluminescent composition using a substance other than a liquid, but this is only marking (marking) of characters, figures, etc. using the chemiluminescent composition on the ground, paper, or the like. The chemiluminescent composition discharged from the container was prepared so as to exhibit high viscosity, and the chemiluminescent composition having high viscosity was not intended to be used in the container.
　また、特許文献４のように偏平状化学発光体が知られているが、発光体の形状や用途などの設計の自由度を高めるために、さらなる化学発光体に適した構造等が求められている。特に、外袋内での、化学組成物の保管時の分離と、使用時の展開に関する構造は、内袋を開封するための引裂きが難しかったり、応力集中しやすいような構造とするための製造条件の調整が難しい場合がある。 Further, a flat chemiluminescent material is known as in Patent Document 4, but in order to increase the degree of freedom in designing the shape and application of the chemiluminescent material, a structure suitable for the chemiluminescent material is required. There is. In particular, the structure related to the separation of the chemical composition during storage and the deployment during use in the outer bag is manufactured so that it is difficult to tear the inner bag to open it or stress is easily concentrated. It may be difficult to adjust the conditions.
　かかる状況下、本発明は、化学発光体の形状の自由度を高めることができ、化学発光に用いられる組成物を展開しやすい状態で収容した化学発光体を提供することを目的とする。 Under such circumstances, an object of the present invention is to provide a chemiluminescent material in which the degree of freedom in the shape of the chemiluminescent material can be increased and the composition used for chemiluminescence is easily developed.
　本発明者は、上記課題を解決すべく鋭意研究を重ねた結果、下記の発明が上記目的に合致することを見出し、本発明に至った。すなわち、本発明は、以下の発明に係るものである。 As a result of intensive research to solve the above problems, the present inventor has found that the following invention meets the above object, and has reached the present invention.

［本発明の化学発光体］
　本発明の化学発光体は、第一の化学組成物と第二の化学組成物との２種の化学組成物を混合することで化学発光を生じさせる化学組成物を用いた化学発光体であって、前記２種の化学組成物を収容する外袋と、前記外袋内に配置され、前記第一の化学組成物を収容し、イージーピールフィルムを用いて形成された第一の内袋と、前記第一の内袋の外部であり、前記外袋の内部に収容された前記第二の化学組成物と、を有する。
　これにより、化学発光に用いられる組成物を展開しやすい状態で収容した化学発光体が提供される。 [Chemiluminescent material of the present invention]
The chemiluminescent material of the present invention is a chemiluminescent material using a chemiluminescent material that produces chemiluminescence by mixing two types of chemical compositions, a first chemical composition and a second chemical composition. An outer bag containing the two types of chemical compositions and a first inner bag arranged in the outer bag and containing the first chemical composition and formed by using an easy peel film. The second chemical composition, which is outside the first inner bag and is housed inside the outer bag.
This provides a chemiluminescent material in which the composition used for chemiluminescence is easily developed.
　本発明者らは、化学発光体の構成について検討し、以下の知見を得た。化学発光用の組成物を利用するにあたっては、混合すると発光が生じる化学組成物を、保管時は分離し、使用時には混合させる必要がある。化学発光体は、種々の形状があるが、例えば偏平状の化学発光体などは少なくとも一方の化学組成物が外袋の中に配置された内袋に保管されている。この外袋内で、内袋内の化学組成物を使用時にどのように展開させるかは非常に重要である。従来、内袋には、応力が集中するような配置や部位を設けるなどの構造が採用されていた。しかし、この内袋に応力をかけるための構造の条件設定は難しい。また、例えば、耐光性などを向上させるものとしてアルミパウチなどが考えられる。しかしアルミパウチは、熱溶着部と、チャック部を有しており、外袋内で使用してもチャック部等を開封することは難しく、収容されている化学組成物を展開しにくい。 The present inventors examined the composition of the chemiluminescent material and obtained the following findings. When using a chemiluminescent composition, it is necessary to separate the chemiluminescent chemical composition, which emits light when mixed, and mix it during use. The chemiluminescent material has various shapes, and for example, a flat chemiluminescent material is stored in an inner bag in which at least one of the chemical compositions is arranged in the outer bag. In this outer bag, how the chemical composition in the inner bag is developed during use is very important. Conventionally, the inner bag has adopted a structure such as an arrangement or a portion where stress is concentrated. However, it is difficult to set the structural conditions for applying stress to this inner bag. Further, for example, an aluminum pouch or the like can be considered as a material for improving light resistance or the like. However, the aluminum pouch has a heat-welded portion and a chuck portion, and it is difficult to open the chuck portion or the like even when used in the outer bag, and it is difficult to develop the contained chemical composition.
　本発明者らは、この内袋を検討した結果、通常、食品等の包装に用いられる接着部の周辺を離隔する方向に引っ張ることで剥離するイージーピールフィルムの利用に着目した。イージーピールフィルムを内袋に利用して、その内部に化学組成物を収容する。この内袋を、偏平状の発光体の外袋内に配置して押圧すると、意外にも離隔する方向に引っ張る力を加えずとも、イージーピールフィルム接着部が部分的に剥離して隙間が生じる。この隙間から、内袋内部の化学組成物を、外袋内に展開することができる。そして、内袋内部の化学組成物と反応する他の化学組成物を外袋内で混合すると、化学発光が生じる。 As a result of examining this inner bag, the present inventors focused on the use of an easy peel film that is peeled off by pulling the periphery of the adhesive portion normally used for packaging foods and the like in a separating direction. The easy peel film is used as an inner bag, and the chemical composition is contained therein. When this inner bag is placed inside the outer bag of the flat illuminant and pressed, the easy peel film adhesive portion is partially peeled off and a gap is generated without applying a pulling force in a direction of unexpected separation. .. From this gap, the chemical composition inside the inner bag can be developed inside the outer bag. Then, when another chemical composition that reacts with the chemical composition inside the inner bag is mixed in the outer bag, chemiluminescence occurs.
［第一の実施形態］
　図１は、本発明の化学発光体の第一の実施形態を説明するための図である。図１は化学発光体１０ａを平面視した概要図である。化学発光体１０ａは、第一の内袋１と、第二の内袋２とを収容した外袋３１を有し、さらに外袋３１の内部には多孔性シート４１が配置されている。 [First Embodiment]
FIG. 1 is a diagram for explaining a first embodiment of the chemiluminescent material of the present invention. FIG. 1 is a schematic view of the chemiluminescent material 10a in a plan view. The chemiluminescent material 10a has an outer bag 31 containing a first inner bag 1 and a second inner bag 2, and a porous sheet 41 is further arranged inside the outer bag 31.
　第一の内袋１には第一の化学組成物が収容されている。第一の内袋１は、イージーピールフィルムを用いて形成されている。第二の内袋２には第二の化学組成物が収容されている。第二の内袋２は、イージーピールフィルムを用いて形成されている。外袋３１は、周囲が接着部３１１により封止されている。 The first inner bag 1 contains the first chemical composition. The first inner bag 1 is formed by using an easy peel film. The second inner bag 2 contains the second chemical composition. The second inner bag 2 is formed by using an easy peel film. The outer bag 31 is surrounded by an adhesive portion 311.
　外袋３１の外部から、第一の内袋１、第二の内袋２を押すと内袋内に収容されている組成物等にかかる内圧が高まりイージーピールフィルムが部分的に剥離し、接着部である熱溶着部１４の隙間から組成物が外袋３１内に展開する。これにより、外袋３１内で、第一の内袋１内に収容されていた第一の化学組成物と、第二の内袋２内に収容されていた第二の化学組成物とが混合して、化学発光が生じる。 When the first inner bag 1 and the second inner bag 2 are pushed from the outside of the outer bag 31, the internal pressure applied to the composition or the like contained in the inner bag increases, and the easy peel film is partially peeled off and adhered. The composition develops in the outer bag 31 from the gap of the heat-welded portion 14 which is a portion. As a result, in the outer bag 31, the first chemical composition contained in the first inner bag 1 and the second chemical composition contained in the second inner bag 2 are mixed. Then, chemiluminescence occurs.
［化学組成物］
　本発明は、第一の化学組成物と第二の化学組成物との２種の化学組成物を混合することで化学発光を生じさせる化学組成物を用いる。ここで、混合することで化学発光を生じさせる２種の化学組成物とは、例えば、化学発光用の蛍光組成物（シュウ酸エステルと色素、溶媒等）と化学発光用の酸化組成物（過酸化水素水のような酸化剤と触媒成分、溶媒等）が挙げられ、この各組成物の組み合わせは適宜変更したものも用いることができる。このような２種の化学組成物のうち、第一の内袋に収容される方を第一の化学組成物とし、他方を第二の化学組成物とする。前述した化学発光用の蛍光組成物と化学発光用の酸化組成物とを用いる場合、一方を第一の化学組成物とした場合、他方が第二の化学組成物として用いられる。 [Chemical composition]
The present invention uses a chemical composition that produces chemiluminescence by mixing two types of chemical compositions, a first chemical composition and a second chemical composition. Here, the two types of chemical compositions that generate chemiluminescence by mixing are, for example, a fluorescent composition for chemiluminescence (oxalate ester and dye, solvent, etc.) and an oxidation composition for chemiluminescence (hydrogen peroxide). An oxidizing agent such as hydrogen peroxide water, a catalyst component, a solvent, etc.) can be mentioned, and a combination of these compositions can be appropriately modified. Of these two types of chemical compositions, the one contained in the first inner bag is designated as the first chemical composition, and the other is designated as the second chemical composition. When the above-mentioned fluorescent composition for chemiluminescence and an oxidation composition for chemiluminescence are used, one is used as the first chemical composition and the other is used as the second chemical composition.
　本発明に用いられる化学組成物は、これらの２種の化学組成物を、少なくとも第一の内袋１の容器により分離する。第一の化学組成物は、この第一の内袋１に収容され、第一の内袋１は、保管時には密閉されている。なお、本発明の化学発光体において、第二の化学組成物は、外袋３１内であり内袋１の外部である周囲に収容されていてもよいし、化学発光体１０ａのように第二の内袋２内に収容されていてもよい。 The chemical composition used in the present invention separates these two types of chemical compositions by at least the container of the first inner bag 1. The first chemical composition is contained in the first inner bag 1, and the first inner bag 1 is hermetically sealed at the time of storage. In the chemiluminescent material of the present invention, the second chemiluminescent material may be contained in the outer bag 31 and the outer periphery of the inner bag 1, or the second chemiluminescent material such as the chemiluminescent material 10a. It may be housed in the inner bag 2 of the.

　第一の内袋１に用いられるイージーピールフィルムは、単層で易剥離性を示すフィルムによるものでもよい。また、易剥離性を示すシーラント（イージーピールシーラント）などを含む積層シートとして、その積層シートのいずれかの部分が易剥離性を有するでもよい。また、積層シートの一部にイージーピールのための層を部分的に設けたものでもよい。 [Inner bag 1]
The inner bag 1 is the first inner bag in the chemiluminescent material of the present invention and contains the first chemical composition. The first inner bag 1 has a bag shape formed by using an easy peel film. The first inner bag 1 seals the first chemical composition contained in the storage, and separates the inside and the outside of the first inner bag 1 inside the outer bag 3. The first inner bag 1 may be formed by using an easy peel film.
The easy peel film used for the first inner bag 1 may be a single-layer, easily peelable film. Further, as a laminated sheet containing a sealant (easy peel sealant) or the like exhibiting easy peeling property, any part of the laminated sheet may have easy peeling property. Further, a layer for easy peel may be partially provided on a part of the laminated sheet.
　イージーピールフィルムは、封止させた部分の少なくとも一部が、開封時に容易に剥離するフィルムである。イージーピールフィルムには、フィルムの特性を利用したものや、二次加工を利用して引裂きしやすくしたものなどがあり、食品等において容器の内容物を容易に取り出すために用いられている。本発明では、特にフィルムの特性を利用したイージーピールフィルムを利用する。フィルムの特性を利用したものとしては、延伸加工技術や、材料の一次構造や二次構造を制御したもの、易剥離性を有する素材を溶着部等にコーティング加工したものなどがあげられる。また、剥離形態として、界面剥離タイプや凝集剥離タイプ、層間剥離タイプがあげられる。本発明においては、剥離後の剥離面を視認する必要性等もなく、これらのいずれの手法や剥離形態のものを採用してもよい。本発明に特に適したイージーピールフィルムとしては、熱溶着において組成が異なる樹脂同士の接着力が低下する性質を利用し、樹脂の配合等を調整することで、接着力の強弱を調整する部分を設けて、応力をかけたとき接着力が低い部分からはがれやすくしたものを用いることができる。 The easy peel film is a film in which at least a part of the sealed portion is easily peeled off at the time of opening. Easy peel films include those that utilize the characteristics of the film and those that are easily torn by using secondary processing, and are used to easily take out the contents of the container in foods and the like. In the present invention, an easy peel film that utilizes the characteristics of the film is particularly used. Examples of those utilizing the characteristics of the film include stretching processing technology, those in which the primary structure and secondary structure of the material are controlled, and those in which a material having easy peelability is coated on a welded portion or the like. Further, examples of the peeling form include an interface peeling type, a cohesive peeling type, and an delamination type. In the present invention, it is not necessary to visually recognize the peeled surface after peeling, and any of these methods or peeled forms may be adopted. As an easy peel film particularly suitable for the present invention, a portion for adjusting the strength of the adhesive force by adjusting the composition of the resins, etc., by utilizing the property that the adhesive force between resins having different compositions decreases in heat welding. It can be provided so that it can be easily peeled off from a portion having a low adhesive force when stress is applied.
　図２は、イージーピールフィルムを用いた内袋１のより詳しい構造を説明するための内袋１のＡＡ断面（図１参照）の概要図である。内袋１は、内側から順に、シーラント層１１、ＰＥＴフィルムの樹脂層１３１、アルミ箔の遮光層１２、ＰＥＴフィルムの樹脂層１３２を有する積層シートを用いたものである。積層シートのシーラント層１１を内側として折り曲げて、化学組成物等を収容するための所定の空間を設けるようにし、その空間を密閉するように、周囲を閉じる。シーラント層１１間を、熱溶着部１４として接着部１５を設けることで周囲を閉じて密閉空間を作る。密閉空間には、第一の化学組成物１６が収容される。 FIG. 2 is a schematic view of an AA cross section (see FIG. 1) of the inner bag 1 for explaining a more detailed structure of the inner bag 1 using the easy peel film. The inner bag 1 is a laminated sheet having a sealant layer 11, a PET film resin layer 131, an aluminum foil light-shielding layer 12, and a PET film resin layer 132 in this order from the inside. The sealant layer 11 of the laminated sheet is bent inside to provide a predetermined space for accommodating a chemical composition or the like, and the periphery is closed so as to seal the space. By providing an adhesive portion 15 as a heat welding portion 14 between the sealant layers 11, the periphery is closed to create a closed space. The first chemical composition 16 is housed in the enclosed space.
［シーラント層１１］
　内袋１のシーラント層１１は、折り重ねられ隣り合うように配置され接着させるために用いられる層である。また、シーラント層１１間は、易剥離性を有する層となるように接着させることができる。化学発光体を使用するときに、内袋１を押圧して内圧を高めることで収容されている化学組成物が内袋１の外に放出しようとする力が生じる。この力により、易剥離性を有する層として接着されたシーラント層間は、界面剥離や凝集剥離、層間剥離等が生じて容易に剥離する。この層は、内袋１としたとき収容される第一の化学組成物１６と直接接触する。第一の化学組成物１６には、各種溶媒等を用いるため、これらの溶媒等に対して耐性を有するものが好ましく用いられる。シーラント層１１には、例えば、エチレンプロピレンコポリマーおよび／またはエチレンαオレフィンコポリマーを含むフィルムなどが用いられる。
　なお、シーラント層１１は、フィルム状のものを他の層と積層して用いてもよいし、遮光層１２や樹脂層１３１などを基材としてコーティングにより積層した層でもよい。シーラント層１１の厚みは材質等に応じて適した厚さとすればよく、例えば１０～２００μｍや、２０～１５０μｍとすることができる。 [Sealant layer 11]
The sealant layer 11 of the inner bag 1 is a layer that is folded and arranged so as to be adjacent to each other and used for adhering. Further, the sealant layers 11 can be adhered so as to be a layer having easy peeling property. When a chemiluminescent material is used, pressing the inner bag 1 to increase the internal pressure creates a force that causes the contained chemical composition to be released to the outside of the inner bag 1. Due to this force, the sealant layers adhered as a layer having easy peeling property are easily peeled off due to interfacial peeling, cohesive peeling, delamination and the like. This layer comes into direct contact with the first chemical composition 16 contained in the inner bag 1. Since various solvents and the like are used for the first chemical composition 16, those having resistance to these solvents and the like are preferably used. For the sealant layer 11, for example, a film containing an ethylene propylene copolymer and / or an ethylene α-olefin copolymer is used.
The sealant layer 11 may be a film-like layer laminated with another layer, or may be a layer laminated with a light-shielding layer 12 or a resin layer 131 as a base material by coating. The thickness of the sealant layer 11 may be an appropriate thickness depending on the material and the like, and may be, for example, 10 to 200 μm or 20 to 150 μm.
［遮光層１２］
　遮光層１２は、内袋１の外部から内袋１の内部へと透過する光を低減する層である。金属箔等の層を用いることが好ましく、例えば、アルミパウチなどに用いられるアルミ箔などを用いることができる。遮光層１２を設けることで、光が照射されることにより、内袋１内に収容されている第一の化学組成物の成分の劣化等を防止することができる。また、これは単に光以外にも遮光層１２等が透過を抑制することができる各種劣化因子（例えば、酸素や、湿気など）の影響低減にも寄与する。これにより、長期保管に適した化学発光体とすることができる。
　遮光層には、遮光性や袋状の形成に適したものを適宜採用することができ、その厚みは材質等に応じて適した厚さとすればよく、例えば１～５０μｍや、２～３０μｍとすることができる。 [Shading layer 12]
The light-shielding layer 12 is a layer that reduces the light transmitted from the outside of the inner bag 1 to the inside of the inner bag 1. It is preferable to use a layer such as a metal foil, and for example, an aluminum foil used for an aluminum pouch or the like can be used. By providing the light-shielding layer 12, it is possible to prevent deterioration of the components of the first chemical composition contained in the inner bag 1 by being irradiated with light. In addition to light, this also contributes to reducing the influence of various deterioration factors (for example, oxygen, humidity, etc.) that can suppress transmission by the light-shielding layer 12 and the like. This makes it possible to obtain a chemiluminescent material suitable for long-term storage.
As the light-shielding layer, a layer suitable for light-shielding property and bag-like formation can be appropriately adopted, and the thickness thereof may be an appropriate thickness depending on the material and the like, for example, 1 to 50 μm or 2 to 30 μm. can do.
［樹脂層１３１、１３２］
　内袋１は、樹脂層１３１と、樹脂層１３２を有する。樹脂層１３１は、シーラント層１１と、遮光層１２との間に設けられる内側樹脂層である。樹脂層１３２は、遮光層１２の外側に設けられる外側樹脂層である。樹脂層１３１、１３２は、ポリエチレンテレフタレート（ＰＥＴ）フィルムを用いて形成されている。ＰＥＴフィルムは、入手しやすい汎用樹脂であり、腰が強く形状維持しやすく、衝撃や引き裂きなどの力が加わっても破壊されにくい。これにより、内袋１の機械的な物性としての形状安定性や、保管時の安定性に大きく寄与する。 [Resin layers 131 and 132]
The inner bag 1 has a resin layer 131 and a resin layer 132. The resin layer 131 is an inner resin layer provided between the sealant layer 11 and the light-shielding layer 12. The resin layer 132 is an outer resin layer provided outside the light-shielding layer 12. The resin layers 131 and 132 are formed by using a polyethylene terephthalate (PET) film. PET film is a general-purpose resin that is easily available, has a strong waist, is easy to maintain its shape, and is not easily broken even when a force such as impact or tear is applied. This greatly contributes to the shape stability of the inner bag 1 as a mechanical property and the stability during storage.
　なお、樹脂層１３１を設けず、遮光層１２とシーラント層１１とが直接接着されたものとしてもよい。それぞれの樹脂層には、機械強度の維持や袋状の形成に適したものを適宜採用することができ、適した厚さとすればよく、例えば１０～２００μｍや、２０～１５０μｍとすることができる。 The resin layer 131 may not be provided, and the light-shielding layer 12 and the sealant layer 11 may be directly adhered to each other. For each resin layer, one suitable for maintaining mechanical strength and forming a bag shape can be appropriately adopted, and the appropriate thickness may be used, for example, 10 to 200 μm or 20 to 150 μm. ..
　また、シーラント層１１や遮光層１２、樹脂層１３１、１３２以外にも、他の層を有するものとしてもよい。これらの隣接する層と層とは、ヒートシール等により接着させてもよいし、接着剤を層間に塗工して接着させてもよいし、各層の表面にコロナ処理などの易接着処理を行って接着させたり、これらを組み合わせて接着させてもよい。 Further, in addition to the sealant layer 11, the light-shielding layer 12, and the resin layers 131 and 132, other layers may be provided. These adjacent layers may be bonded by heat sealing or the like, an adhesive may be applied between the layers to bond them, or the surface of each layer may be easily bonded by corona treatment or the like. Or they may be combined and adhered.
　これらの層間を接着剤で接着させるとき、接着剤としては、ポリエステル系樹脂を含む接着剤を用いることが好ましい。シーラント層１１と、樹脂層１３１とは、シーラント層１１が、耐溶剤性等を有していても、保管時に浸透等して、樹脂層１３１等まで浸食する場合がある。ポリエステル系樹脂は、イージーピールフィルムとするためのシーラント層１１との接着性に優れ、化学発光用の組成物に用いる溶媒等に対する耐性も優れている。接着手法は、接着剤の種類や工程を考慮して適宜選択することができ、例えば、液状で塗工したりシート状で配置して、経時変化に伴い固化させたり、ホットメルト、押圧、ＵＶ硬化などで接着させることができる。 When adhering these layers with an adhesive, it is preferable to use an adhesive containing a polyester resin as the adhesive. Even if the sealant layer 11 has solvent resistance and the like, the sealant layer 11 and the resin layer 131 may permeate during storage and erode to the resin layer 131 and the like. The polyester-based resin has excellent adhesiveness to the sealant layer 11 for forming an easy peel film, and also has excellent resistance to solvents and the like used in the composition for chemiluminescence. The bonding method can be appropriately selected in consideration of the type and process of the adhesive. For example, it can be coated in a liquid state or arranged in a sheet form to solidify with time, hot melt, pressing, UV. It can be adhered by curing or the like.
［熱溶着部１４］
　熱溶着部１４は、シーラント層１１が隣り合うように重ね合わせて、シーラント層１１間を熱溶着して接着させた部分である。内袋１に化学組成物を収容してその周囲を熱溶着部１４で閉じることで、化学発光体１０ａの保管時に、第一の化学組成物１６を収容した状態で密閉したものとする。一方、シーラント層１１間は熱溶着されても強い内圧等によって易剥離性を有する状態のため、使用時に外袋３１の外側から内袋１を押圧すると、その一部が剥離して、収容されていた化学組成物が内袋１の外部に展開しやすい状態となる。 [Heat welding part 14]
The heat-welded portion 14 is a portion in which the sealant layers 11 are overlapped so as to be adjacent to each other and the sealant layers 11 are heat-welded and adhered to each other. By accommodating the chemical composition in the inner bag 1 and closing the periphery thereof with the heat welding portion 14, it is assumed that the first chemical composition 16 is sealed in the state of accommodating the chemiluminescent material 10a at the time of storage. On the other hand, since the sealant layers 11 are easily peeled off due to strong internal pressure or the like even if they are heat-welded, when the inner bag 1 is pressed from the outside of the outer bag 31 during use, a part of the inner bag 1 is peeled off and accommodated. The chemical composition that has been used is in a state where it can be easily expanded to the outside of the inner bag 1.
［接着部１５］
　内袋１は、易剥離性を有する積層シートにより形成されており、袋状をなすように接着部１５が設けられている。接着部１５は、積層シートの折り返しでなされる辺以外の部分に設け、内袋１内に収容される化学組成物を密閉するように設けられる。例えば、１枚の平面状の積層シートを平面視したとき方形となるように折り曲げて、折り曲げた辺以外の３辺の内いずれか２辺を接着部１５として先に閉じて、１辺が開口された袋状として、この開口された辺側から化学組成物を入れて、その後、開口されていた辺も接着部１５として閉じることで、化学組成物が収容された内袋１を得ることができる。接着部１５は、熱溶着部１４により溶着された部分によるものでもよいし、熱溶着以外の他の手法により接着させたものでもよい。 [Adhesive portion 15]
The inner bag 1 is formed of a laminated sheet having easy peelability, and an adhesive portion 15 is provided so as to form a bag. The adhesive portion 15 is provided on a portion other than the folded side of the laminated sheet, and is provided so as to seal the chemical composition contained in the inner bag 1. For example, one flat laminated sheet is bent so as to be rectangular when viewed in a plan view, and any two of the three sides other than the bent side are closed first as the adhesive portion 15, and one side is opened. The inner bag 1 containing the chemical composition can be obtained by putting the chemical composition from the opened side in the shape of a rectangular bag and then closing the opened side as the adhesive portion 15. it can. The bonded portion 15 may be formed by a portion welded by the heat-welded portion 14, or may be bonded by a method other than heat welding.

An openable laminated film (for example, JP-A-2005-28679) or the like can also be used.
［第二の内袋２］
　第一の実施形態に係る化学発光体１０ａは、第二の化学組成物を収容する第二の内袋２を有する。第二の内袋２は、前述した第一の内袋１と同様に、易剥離性を有する積層シートなどのイージーピールフィルムを用いた内袋を利用することができる。第二の内袋２は、この第一の内袋１で収容する第一の化学組成物１６に代え、第二の化学組成物を収容する。 [Second inner bag 2]
The chemiluminescent material 10a according to the first embodiment has a second inner bag 2 containing the second chemical composition. As the second inner bag 2, similarly to the first inner bag 1 described above, an inner bag using an easy peel film such as a laminated sheet having easy peelability can be used. The second inner bag 2 stores the second chemical composition in place of the first chemical composition 16 contained in the first inner bag 1.
［外袋３１］
　外袋３１は、内袋１、内袋２、および多孔性シート４１を収容し、これらの内容物を密閉する外側容器である。外袋３１は、ポリエチレンや、ポリプロピレン、ポリウレタン、シリコン樹脂などを用いて形成される。また、これらに、他の素材を組み合わせたものを用いてもよい。２枚のシートを重ね、内袋１、内袋２、および多孔性シート４１を収容する空間をなす領域を設けた後、重ねた２枚のシートの周囲をホットメルトなどの各素材に応じた接着手段で接着させた接着部３１１により密閉する。化学発光体１０ａの全体的な外観は、外袋３１の外形に応じたものとなり、化学発光体１０ａの用途等に応じて、適宜、その形状や大きさ、厚さなどが選択される。なお、本発明の化学発光体の外側容器は、袋状のものに加えて、収容されている内袋１、内袋２を押圧することができる任意の形状の容器も含む。 [Outer bag 31]
The outer bag 31 is an outer container that houses the inner bag 1, the inner bag 2, and the porous sheet 41 and seals the contents thereof. The outer bag 31 is formed of polyethylene, polypropylene, polyurethane, silicone resin, or the like. Further, a combination of these with other materials may be used. After stacking the two sheets and providing an area forming a space for accommodating the inner bag 1, the inner bag 2, and the porous sheet 41, the circumference of the two stacked sheets was adapted to each material such as hot melt. It is sealed by the adhesive portion 311 bonded by the adhesive means. The overall appearance of the chemiluminescent material 10a depends on the outer shape of the outer bag 31, and the shape, size, thickness, and the like thereof are appropriately selected according to the application of the chemiluminescent material 10a and the like. The outer container of the chemiluminescent material of the present invention includes not only a bag-shaped container but also a container having an arbitrary shape capable of pressing the inner bag 1 and the inner bag 2 contained therein.
　本発明の化学発光体は、外袋が、ポリエチレン（ＰＥ）および／またはポリプロピレン（ＰＰ）製シートの内層と、ポリエチレンテレフタレート（ＰＥＴ）製シートの外層との積層シートであることが好ましい。このような構成とすることで、内層のシートにより外袋内の化学組成物に対する耐溶媒性を維持しつつ、靱性が高いＰＥＴにより、内層のシートや外袋の内部構造に損傷を与えにくくなるため、安全性に優れている。また、発光体として、複雑な形状の成形も行いやすく、ヒートシールにより封止することができるため任意の形状で製造しやすい。 The chemiluminescent material of the present invention preferably has an outer bag of a laminated sheet of an inner layer of a polyethylene (PE) and / or polypropylene (PP) sheet and an outer layer of a polyethylene terephthalate (PET) sheet. With such a configuration, the inner layer sheet maintains the solvent resistance to the chemical composition in the outer bag, and the highly tough PET makes it difficult to damage the inner structure of the inner layer sheet and the outer bag. Therefore, it is excellent in safety. Further, as the light emitting body, it is easy to form a complicated shape, and since it can be sealed by heat sealing, it is easy to manufacture it in an arbitrary shape.
　この積層シートに用いる、ポリエチレン（ＰＥ）および／またはポリプロピレン（ＰＰ）製シートの内層とは、ポリエチレンとポリプロピレンのいずれかあるいは双方を合わせたものを主たる成分として、適宜、成形助剤等を混合して成形されたシートである。このシートは、外袋内部の化学組成物等と直接接触し、これらの化学組成物等が漏出することを防止するために、耐溶媒性が高く、通液性や通気性が低いものが用いられる。また、その厚みは、内容物の漏出を十分に防止することができるものであればよいが、１μｍ～５００μｍ程度や、５０～５００μｍ程度のものが用いられる。 The inner layer of the polyethylene (PE) and / or polypropylene (PP) sheet used for this laminated sheet is mainly composed of either or both of polyethylene and polypropylene, and a molding aid or the like is appropriately mixed. It is a sheet formed by This sheet has high solvent resistance and low liquid permeability and air permeability in order to prevent the chemical compositions inside the outer bag from leaking out due to direct contact with the chemical compositions inside the outer bag. Be done. The thickness thereof may be any as long as it can sufficiently prevent leakage of the contents, but those having a thickness of about 1 μm to 500 μm or about 50 to 500 μm are used.
　ポリエチレンテレフタレート（ＰＥＴ）製シートの外層とは、ポリエチレンテレフタレートを主たる成分として、適宜、成形助剤等を混合して成形されたシートである。このシートは、外袋内部の化学組成物等が漏出することを防止するために用いられる。このポリエチレンテレフタレートは内層に用いられるＰＥ、ＰＰと比べて耐溶媒性が低い傾向にあるが、靱性や衝撃強度等の機械特性が高い傾向にあるため、外部からの衝撃を内部に伝達しにくく、また、内袋の破割等の内部で生じた衝撃によっても破れたりしにくく発光体全体の保護性が優れているため、外層の保護材として適したものである。また、その厚みは、内容物の漏出を十分に防止することができるものであればよいが、例えば１０μｍ～５００μｍ程度のものが用いられる。また、内層に用いられるＰＥ／ＰＰとの接着性にも優れている。 The outer layer of the polyethylene terephthalate (PET) sheet is a sheet formed by appropriately mixing a molding aid or the like with polyethylene terephthalate as a main component. This sheet is used to prevent the chemical composition and the like inside the outer bag from leaking out. This polyethylene terephthalate tends to have lower solvent resistance than PE and PP used for the inner layer, but tends to have high mechanical properties such as toughness and impact strength, so it is difficult to transmit the impact from the outside to the inside. In addition, it is not easily torn by an impact generated inside such as the inner bag being broken, and has excellent protection of the entire illuminant, so that it is suitable as a protective material for the outer layer. The thickness thereof may be such that it can sufficiently prevent leakage of the contents, and for example, a thickness of about 10 μm to 500 μm is used. It also has excellent adhesion to PE / PP used for the inner layer.
［多孔性シート４１］
　外袋３１の内部には、多孔性シート４１が配置されている。多孔性シートとは、多量の細孔があるシートであり、化学組成物を浸透させ保持することができるものである。このようなシートとしては、ポリエチレン（ＰＥ）やポリプロピレン（ＰＰ）、レーヨンなどを素材とする織布や不織布等が挙げられ、これらの素材を単独で用いた不織布や、あるいは複数組み合わせた複合不織布を用いることができる。
　この多孔性シート４１は、展開された化学発光用の組成物の浸透・保持性を有することが好ましい。また、多孔性シート４１は、化学発光用の組成物の溶媒に一定の耐性があり、それらの化合物と接しても分解しにくいように、適宜、複数の素材を組み合わせた複合不織布を用いることが好ましい。この多孔性シート４１の厚みは３０μｍ以上程度のものが用いられ、化学発光体の用途にも併せて適宜、２ｍｍ以下や１ｍｍ以下、５００μｍ以下程度の厚みのものが用いられる。 [Porosity sheet 41]
A porous sheet 41 is arranged inside the outer bag 31. The porous sheet is a sheet having a large number of pores, and is capable of permeating and retaining a chemical composition. Examples of such a sheet include woven fabrics and non-woven fabrics made of polyethylene (PE), polypropylene (PP), rayon, etc., and non-woven fabrics using these materials alone or composite non-woven fabrics obtained by combining a plurality of these materials can be used. Can be used.
The porous sheet 41 preferably has the permeation / retention property of the developed chemiluminescent composition. Further, the porous sheet 41 may use a composite non-woven fabric in which a plurality of materials are appropriately combined so that the porous sheet 41 has a certain resistance to the solvent of the chemiluminescent composition and is not easily decomposed even if it comes into contact with those compounds. preferable. The thickness of the porous sheet 41 is about 30 μm or more, and a thickness of about 2 mm or less, 1 mm or less, and 500 μm or less is appropriately used according to the use of the chemiluminescent material.
　この多孔性シート４１は、化学発光体の外袋の形状に合わせて内部に広く配置される。このような構成とすることで、外袋内で鉛直方向の下側に展開された化学組成物がたまることを防ぐことができ、化学発光体全体に広く均一な発光部を設けることができる。 The porous sheet 41 is widely arranged inside according to the shape of the outer bag of the chemiluminescent material. With such a configuration, it is possible to prevent the chemical composition developed downward in the vertical direction from accumulating in the outer bag, and it is possible to provide a wide and uniform chemiluminescent portion in the entire chemiluminescent material.
　多孔性シート４１には、化学組成物の一方の液を浸透させておいてもよい。このような化学組成物には高粘度化学組成物を用いてもよい。高粘度化学組成物とは、化学組成物に増粘剤を含むことで粘度を上昇させたものである。化学発光用の酸化組成物を例にすると、従来の代表的な組成としては、過酸化水素水、酸化剤、触媒および溶媒の混合物が用いられており、粘度が低い液であった。ここに、さらに化学組成物中に増粘剤を加えて粘度を上昇させることで、外袋内に配置される多孔性シート４１による保持性も向上し、化学発光体内で沈降しにくくなる。 The porous sheet 41 may be impregnated with one of the liquids of the chemical composition. A high-viscosity chemical composition may be used for such a chemical composition. The high-viscosity chemical composition is one in which the viscosity is increased by containing a thickener in the chemical composition. Taking an oxidation composition for chemiluminescence as an example, a mixture of a hydrogen peroxide solution, an oxidizing agent, a catalyst and a solvent has been used as a typical composition in the past, and the liquid has a low viscosity. By further adding a thickener to the chemical composition to increase the viscosity, the retention by the porous sheet 41 arranged in the outer bag is also improved, and it becomes difficult for the chemiluminescent material to settle.
　増粘剤としては、任意の粘度が得られるものであれば特に限定されず、高粘度化学組成物中に使用する溶媒等の成分を著しく劣化させることがないものを適宜選択することができる。この増粘剤としては、ワックスや超低分子量ポリエチレン、ペトロラタム物質、パラフィン、ポリマー、ヒュームドシリカ、ポリマー性増粘剤（ポリアミド、塩化ビニル樹脂、ポリスチレン、ポリアクリレートなど）、ゴム改質剤、ゴム、デンプン、食用ゲル、ポリアクリルアミドおよびヒュームドシリカからなる群から選択される１以上の物質などを用いることができる。また、これらの増粘剤は適宜、組み合わせて用いることもできる。 The thickener is not particularly limited as long as it can obtain an arbitrary viscosity, and an agent that does not significantly deteriorate components such as a solvent used in the high-viscosity chemical composition can be appropriately selected. Examples of this thickener include wax, ultra-low molecular weight polyethylene, petrolatum substance, paraffin, polymer, fumed silica, polymer thickener (polyamide, vinyl chloride resin, polystyrene, polyacrylate, etc.), rubber modifier, rubber. , Stand, edible gel, one or more substances selected from the group consisting of polyacrylamide and fumed silica, and the like can be used. Further, these thickeners can be used in combination as appropriate.
　化学発光体１０ａは、柔軟性があり、内袋１や、内袋２を外部から押圧すると、イージーピールフィルムを用いた接着部分が少なくとも一部剥離して開口し、その開口部からそれぞれの化学組成物が、外袋３１内に展開する。この外袋３１内で、内袋１、内袋２内に収容されていたそれぞれの化学組成物が混合して化学発光が生じる。これらの化学組成物は、多孔性シート４１に吸液されて、その場で発光するため、化学発光体１０ａの全体が光って見える。 The chemiluminescent material 10a is flexible, and when the inner bag 1 or the inner bag 2 is pressed from the outside, at least a part of the adhesive portion using the easy peel film is peeled off and opened, and each chemiluminescent material is opened from the opening. The composition develops in the outer bag 31. In the outer bag 31, the respective chemical compositions contained in the inner bag 1 and the inner bag 2 are mixed to generate chemiluminescence. Since these chemical compositions are absorbed by the porous sheet 41 and emit light on the spot, the entire chemiluminescent material 10a appears to shine.
［第二の実施形態］
　図３は、本発明の化学発光体の第二の実施形態を説明するための図である。図３は化学発光体１０ｂを平面視した概要図である。化学発光体１０ｂは、第一の内袋１を収容した外袋３２を有し、さらに外袋３２の内部には多孔性シート４１１、多孔性シート４１２が配置されている。化学発光体１０ｂにおいては、第二の化学組成物は、外袋３２内に収容され、多孔性シート４１１や多孔性シート４１２に吸液されたり、外袋３２内で自在に移動できる状態となっている。 [Second Embodiment]
FIG. 3 is a diagram for explaining a second embodiment of the chemiluminescent material of the present invention. FIG. 3 is a schematic view of the chemiluminescent material 10b in a plan view. The chemiluminescent material 10b has an outer bag 32 containing the first inner bag 1, and a porous sheet 411 and a porous sheet 412 are arranged inside the outer bag 32. In the chemiluminescent material 10b, the second chemical composition is housed in the outer bag 32 and is in a state where it can be absorbed by the porous sheet 411 or the porous sheet 412 or can be freely moved in the outer bag 32. ing.
　図４は、化学発光体１０ｂの一部断面図である。第一の内袋１は、多孔性シート４１１、４１２間に配置されている。この化学発光体１０ｂのように、外袋に配置される多孔性シートは、外袋内に複数の層を有するように配置することができる。複数の層とするために、複数枚の多孔性シートを配置したり、１枚の多孔性シートを折り曲げて複数の層となるように配置してもよい。複数の層を有するように配置することで、それぞれの層（シート）の吸液量を制御して発光性を調整したり、全体としての機械的強度を向上させたりといった、より高度な設計を行うことができる。
　また、前述のように、この複数の層の間に内袋を設ければ、外観から内袋が見えにくくなるため、両面からの意匠性が優れたものとなる。また、この複数の層として、吸液性が高い吸液性シート層と、吸液性が低く靱性が高い疎液性シート層とを有することが好ましい。吸液性が高いシートが化学組成物をより多く保持し、この吸液性シートよりも吸液性が劣るシートはより機械的強度が高く、化学発光体の形状維持により寄与する構成とすることで、発光の均一性と、化学発光体としての形状の安定性とが向上する。 FIG. 4 is a partial cross-sectional view of the chemiluminescent material 10b. The first inner bag 1 is arranged between the porous sheets 411 and 412. Like the chemiluminescent material 10b, the porous sheet arranged in the outer bag can be arranged so as to have a plurality of layers in the outer bag. In order to form a plurality of layers, a plurality of porous sheets may be arranged, or one porous sheet may be bent and arranged so as to form a plurality of layers. By arranging so as to have multiple layers, more advanced design such as controlling the amount of liquid absorption of each layer (sheet) to adjust the light emission and improving the mechanical strength as a whole can be achieved. It can be carried out.
Further, as described above, if the inner bag is provided between the plurality of layers, the inner bag is difficult to see from the outside, so that the designability from both sides is excellent. Further, as the plurality of layers, it is preferable to have a liquid-absorbent sheet layer having high liquid-absorbing property and a sparse-liquid sheet layer having low liquid-absorbing property and high toughness. A sheet with high liquid absorption retains more of the chemical composition, and a sheet with lower liquid absorption than this liquid-absorbent sheet has higher mechanical strength and contributes to maintaining the shape of the chemiluminescent material. As a result, the uniformity of light emission and the stability of the shape as a chemiluminescent material are improved.
　また、外袋の内部に配置される多孔性シートが複数の層を有する場合、その層の間に内袋を配置することが好ましい。このように配置することで、一部前述したように、外観から内袋が見えにくくなるため、両面からの意匠性が優れたものとなる。また、内袋内部の液状化学組成物が、表面側の多孔性シートと、裏面側の多孔性シートとの両面の方向に展開して保持されるため、短時間で均一に発光する。 Further, when the porous sheet arranged inside the outer bag has a plurality of layers, it is preferable to arrange the inner bag between the layers. By arranging in this way, as described above, the inner bag is difficult to see from the outside, so that the design from both sides is excellent. Further, since the liquid chemical composition inside the inner bag is developed and held in the directions of both sides of the porous sheet on the front surface side and the porous sheet on the back surface side, it emits light uniformly in a short time.
［内袋内の化学組成物］
　本発明の化学発光体は、内袋１内に蛍光組成物が収容されていることが好ましい。全体として薄い偏平状の発光体を提供するとき、外袋および内袋等も一般的な筒状の化学発光体と比べると各層が薄い傾向にある。このため、外袋の外部から空気中の酸素や水分等の気体も通過しやすくなる。このため、空気と接触する機会が多くなりやすい。
　このとき、化学発光用の酸化組成物は、比較的、空気と接触しても劣化しにくい。一方、蛍光組成物は、空気中の水分（湿気）によって蛍光組成物中のシュウ酸エステルの加水分解が生じて劣化する場合がある。よって、内袋１内の第一の化学組成物が化学発光用の蛍光組成物であり、内袋２を用いずに外袋３２内に直接収容することができる第二の化学組成物を、酸化組成物とすることで、蛍光組成物が空気と接触することが減るため、より長期間保管に適した化学発光体とすることができる。特に、本発明の化学発光体に用いるイージーピールフィルムは、遮光層を有するものとすることができるため、蛍光組成物等の長期保管により適している。 [Chemical composition in inner bag]
In the chemiluminescent material of the present invention, it is preferable that the fluorescent composition is contained in the inner bag 1. When providing a thin flat chemiluminescent material as a whole, each layer of the outer bag, the inner bag, and the like tends to be thinner than that of a general tubular chemiluminescent material. Therefore, gases such as oxygen and moisture in the air can easily pass from the outside of the outer bag. For this reason, there are many opportunities for contact with air.
At this time, the oxidation composition for chemiluminescence is relatively unlikely to deteriorate even when in contact with air. On the other hand, the fluorescent composition may be deteriorated due to hydrolysis of the oxalic acid ester in the fluorescent composition due to moisture (humidity) in the air. Therefore, the first chemical composition in the inner bag 1 is a fluorescent composition for chemiluminescence, and the second chemical composition that can be directly contained in the outer bag 32 without using the inner bag 2 is By using the oxidation composition, the fluorescent composition is less likely to come into contact with air, so that a chemiluminescent material suitable for storage for a longer period of time can be obtained. In particular, the easy peel film used for the chemiluminescent material of the present invention can have a light-shielding layer, and is therefore more suitable for long-term storage of a fluorescent composition or the like.
　本発明の化学発光体は、任意の形状とすることができる。本発明の化学発光体は、外側容器の外側から押圧することで内袋を押しつぶし、内袋に収容されている化学組成物を外側容器内に展開させる。このため、外側容器は、変形しやすい柔軟な素材を用いて、変形させやすい形状であることが好ましい。外側容器は、例えば、可撓性を有する樹脂部材などを用いて成形することができる。また、樹脂部材の材質にもよるが、例えば、厚み１ｍｍ以下や５００μｍ以下として変形させやすいものとすることが好ましい。 The chemiluminescent material of the present invention can have any shape. The chemiluminescent material of the present invention crushes the inner bag by pressing from the outside of the outer container, and develops the chemical composition contained in the inner bag into the outer container. Therefore, it is preferable that the outer container uses a flexible material that is easily deformed and has a shape that is easily deformed. The outer container can be molded using, for example, a flexible resin member or the like. Further, although it depends on the material of the resin member, it is preferable that the thickness is 1 mm or less or 500 μm or less so that it can be easily deformed.
　本発明の化学発光体の形状は、例えば、偏平状としたり、偏平状の状態で内袋押圧後に膨らませるものとしたり、各種構造体等の表面に張り付けて用いるものとすることができる。典型的な形状としては、コースターやワッペン等のように用いることができる。また、この他にも、偏平状の装飾具全般に用いることができ、マスクのような偏平状の装身具としても用いることができる。 The chemiluminescent material of the present invention may be, for example, flattened, inflated after pressing the inner bag in a flattened state, or attached to the surface of various structures or the like. As a typical shape, it can be used like a coaster, an emblem, or the like. In addition to this, it can be used for all flat-shaped ornaments, and can also be used as a flat-shaped accessory such as a mask.

　図５中段の像は、ポリプロピレン性の外袋を用いた化学発光体であり、多孔性シートは１層としたものである。図５下段の像は、シリコン製の外袋を用いた化学発光体である。いずれも、前述のポリウレタンを用いた化学発光体に準じて使用することで発光させることができる。 FIG. 5 is an image of a typical chemiluminescent material.

Two circular porous sheets are arranged in the outer bag, and between the first inner bag containing the first chemical composition and the second inner bag containing the second chemical composition. The bag was placed. By sandwiching the porous sheet, the first inner bag, and the second inner bag and pressing from the outside of the outer bag, the chemical composition is developed from each inner bag and chemiluminescence is generated in the outer bag.
