Embodiments of the present invention will be described in detail below. is not limited to the contents of In this specification, when the expression "~" is used, it is used as an expression including the numerical values before and after it.

[First embodiment]
FIG. 1 shows a first embodiment of the pouch-shaped chemiluminescent material of the present invention. FIG. 1 is a plan view of the bag-shaped chemiluminescent body 10. FIG. The bag-shaped chemiluminescent body 10 has an outer bag 31 and a chemiluminescent member 2 enclosed in the outer bag 31 . The chemiluminescent member 2 has a luminescent member bag 22 containing a first inner bag 211 and a second inner bag 212, and a porous sheet 23 is arranged in the luminescent member bag 22 in a spread state. It is The first inner bag 211 contains the first chemiluminescent composition, and the second inner bag contains the second chemiluminescent composition. Chemiluminescence occurs when the first chemiluminescent composition and the second chemiluminescent composition are mixed. The outer bag 31 is provided with a fluid introduction member 4 . The introduction member 4 can introduce the fluid into the bag-shaped chemiluminescent body 10 from the introduction port 41 . The left end of the chemiluminescent member 2 is fixed to the left end of the outer bag 31 with a fixing portion 32 . The right end of the chemiluminescent member 2 is fixed to the right end of the outer bag 31 with a fixing portion 33 . This fixation can be performed, for example, by welding, bonding with an adhesive, or fixing with a fixing member such as a clip.

FIG. 2 is a schematic cross-sectional view of the bag-shaped chemiluminescent body 10. As shown in FIG. Moreover, FIG. 2 is a figure for demonstrating the operation which supplies fluid, such as a gas and a liquid, to the bag-shaped chemiluminescent body 10, and inflates it. By inserting the straw 5 into the introduction port 41 of the introduction member 4 and introducing the fluid into the bag-shaped chemiluminescent body 10 , the fluid is supplied into the outer bag 31 to expand it. For example, by using the introduction port 41 as a gas blowing port, a person can inflate the balloon by exhaling the gas.

The introduction member 4 is formed of two layers of adhesive sheets, and the introduction member 4 has a structure in which a straw is easily introduced between the two layers of adhesive sheets from the outside of the bag-shaped chemiluminescent body 10. . For this introduction, the two-layered adhesive sheet is provided with a fluid passage with reduced adhesiveness, so that the straw 5 can be inserted into the inlet 41 and the fluid can be introduced from between the adhesive sheets. Only the passage portion is selectively opened by the opening, and the fluid can easily pass through. The introduction member 4 is fixed to the outer bag 31 by welding or using an adhesive.
Since the introduction port 41 of the introduction member 4 is arranged outside the chemiluminescence member 2 and the fluid supplied from the introduction member 4 does not enter the chemiluminescence member 2, the shape of the chemiluminescence member 2 is stable and the internal By stabilizing the light emission, the light emission of the bag-shaped chemiluminescent body 10 as a whole becomes more stable.

FIG. 3 is a schematic cross-sectional view of bag-shaped chemiluminescent body 10 after it has been supplied with fluid and expanded. By supplying fluid to the space 34 using the straw 5 as shown in FIG. 2, the inside of the outer bag 31 is inflated with the fluid and shaped like a balloon. When the supply is completed and the straw 5 is pulled out, the two layers of adhesive sheets forming the introduction member 4 are adhered to each other and closed, and a force acts in the space 34 to expand the passage of the introduction member 4. The adhesion state is maintained and the fluid becomes difficult to escape.

In the flat state shown in FIG. 1, the bag-shaped chemiluminescent body 10 presses the portions corresponding to the first inner bag 211 and the second inner bag 212, and the first chemiluminescence contained in each The body composition and the second chemiluminescent composition are leaked into the luminous member bag 22 and mixed. In the flat state, the mixed composition for a chemiluminescence body is expanded by hand or vibrated up and down so as to develop in contact with the porous sheet 23 in the light-emitting member bag 22 . The porous sheet 23 retains a liquid or solid composition for a chemiluminescent body in its pores or the like. As a result, the composition for a chemiluminescent body is widely spread and held in the light-emitting member bag 22 .

After mixing and developing this composition for a chemiluminescent body, as described above, by inflating using a straw 5 as shown in FIG. Become. This chemiluminescence is easily visible even in a dark place, and the bag-shaped chemiluminescence body 10 accompanies fantastic luminescence.

[Chemiluminescence member 2]
The chemiluminescent member 2 contains a first composition for a chemiluminescent body and a second composition for a chemiluminescent body that emit light when mixed. As such a chemiluminescence means, a known one can be appropriately adopted. For example, as the composition that emits light when mixed, a chemiluminescent material that emits light when a fluorescent liquid and an oxidizing liquid are mixed can be preferably used.
The chemiluminescent member preferably uses a light and flat chemiluminescent body that emits light uniformly and widely in the bag-shaped chemiluminescent body 10. For example, JP-A-2004-265809 and JP-A-2016-150956. Publications can be referred to and used as appropriate.

[First inner bag 211, second inner bag 212]
The first chemiluminescent composition is contained in the first inner bag 211 . Also, the second composition for a chemiluminescent body can be contained in the second inner bag 212 . In addition, the second composition for chemiluminescent bodies should just be enclosed in the light-emitting member bag 22 and separated from the first composition for chemiluminescent bodies during storage. Therefore, the second chemiluminescent composition may be contained in the light emitting member bag 22 outside the first inner bag 211 without using the second inner bag, or the porous sheet 23 It may be held in

The first inner bag and the second inner bag (hereinafter sometimes collectively referred to as "luminous body inner bag") are those having resistance to the contained chemiluminescent composition. can be done. For example, a bag molded from a resin sheet, such as polyethylene (PE) or polypropylene (PP), which is highly resistant to solvents and the like used in chemiluminescent bodies, is preferably used. Also, an aluminum pouch obtained by laminating aluminum vapor deposition or an aluminum sheet layer can be used.

For example, when the first chemiluminescent composition is an oxidizing liquid, the second chemiluminescent composition is a fluorescent liquid. These compositions are preferably prepared as highly fluid liquid or gel chemical compositions. Since these chemical compositions have high fluidity, they quickly leak out of the inner bag during use and are spread and mixed in the light-emitting member bag 22 .

It is preferable to provide an easy-to-split portion in the inner bag for the light emitter. For example, the easy-to-split portion is formed by making the inner bag from a sheet having a thin region, or by making the part where the inner bag is fastened with tape easy to break depending on the adhesive strength of the tape, or by Since the heat-sealed portion has less flexibility than other regions, stress is likely to concentrate, so that it can function as an easily split portion. Such an easy-to-break portion easily breaks when pressure is applied to break the inner bag.

[Light emitting member bag 22]
The light-emitting member bag 22 is stored and used with the composition for a chemiluminescent substance enclosed therein. For this reason, it is preferable that the light-emitting member bag 22 is formed of a sheet or the like that is resistant to the organic solvent or the like used in the chemiluminescent composition. In addition, the light-emitting member bag 22 has translucency in order to transmit the chemiluminescence inside thereof to the outside. The light-emitting member bag 22 may be transparent, or may have light diffusing properties, and may be cloudy or appropriately colored.

The light emitting member bag 22 can be a laminated sheet of an inner layer made of polyethylene (PE) and/or polypropylene (PP) sheet and an outer layer made of polyethylene terephthalate (PET) sheet. With such a configuration, the inner layer sheet maintains solvent resistance to the chemical composition in the outer bag, while the tough PET makes it difficult to damage the inner layer sheet and the inner structure of the outer bag. Therefore, it has excellent safety.

[Porous sheet 23]
A porous sheet 23 is arranged inside the light emitting member bag 22 . A porous sheet is a sheet having a large number of pores, and is capable of permeating and retaining the chemiluminescent composition. Examples of such sheets include woven fabrics and nonwoven fabrics made of polyethylene (PE), polypropylene (PP), rayon, and the like. Non-woven fabrics can be used.

This porous sheet preferably has permeation and retention of the chemiluminescent composition and a certain shape retention (mechanical strength). Therefore, as the porous sheet, there is resistance to the compounds used in the chemiluminescent composition, especially the solvent, and so that it is difficult to decompose even when in contact with those compounds, a composite nonwoven fabric or the like that combines a plurality of materials is used. may The thickness of the porous sheet is about 30 μm or more or about 50 μm or more, and the thickness is about 2 mm or less, 1 mm or less, or about 500 μm or less depending on the application of the flat chemiluminescent material.

This porous sheet is widely arranged inside according to the shape of the luminescent member bag 22 of the chemiluminescent member 2 . By adopting such a configuration, it is possible to prevent the composition from accumulating on the lower side in the vertical direction within the outer bag, and it is possible to provide a wide and uniform light-emitting portion over the entire chemiluminescent member 2 .

It is preferable to arrange the porous sheet 23 arranged in the light emitting member bag 22 so as to have a plurality of layers in the light emitting member bag 22 . That is, it is preferable to arrange a plurality of porous sheets 23 or to arrange a plurality of layers by folding one porous sheet. By arranging it so that it has multiple layers, it is possible to control the amount of liquid absorbed by each layer (sheet) to adjust the luminescence, and to improve the mechanical strength as a whole. It can be carried out. In addition, if the luminous body inner bags (211, 212) are provided between the plurality of layers, the chemiluminescent composition can be spread out more easily and held by the porous sheet 23 more easily.

[Outer bag 31]
The outer bag 31 is a bag that can hold a fluid such as gas in its internal space 34 and that can be inflated by introduction of the fluid or the like. As the outer bag 31, a bag molded from a flexible sheet-like material such as a thermoplastic resin sheet such as polyethylene, polypropylene, or polyethylene terephthalate can be used. The outer bag 31 may be a laminated sheet of, for example, an inner layer of polyethylene (PE) and/or polypropylene (PP) sheets and an outer layer of polyethylene terephthalate (PET) sheets. In the case of such a configuration, even if the chemiluminescent composition partially leaks from the chemiluminescent member 2 due to the inner layer sheet, further leakage of the chemical composition in the outer bag 31 is prevented, and the high toughness PET , the inner layer sheet and the inner structure of the outer bag are less likely to be damaged, so they are excellent in safety.

Moreover, the outer bag 31 is preferably a bag formed using a light-diffusing film having translucency. As a result, a bag-shaped chemiluminescent body can be obtained in which the chemiluminescence inside is projected and the entire body emits light diffusely with excellent uniformity. In addition, since the porous sheet 23 is also arranged inside, the diffusion inside and the diffusion of the outer bag 31 make the luminous body excellent in uniformity. The light diffusing film may be appropriately selected and used using the total light transmittance and haze according to JIS standards as indicators. The total light transmittance may be 60% or more, 70% or more, 75% or more, or 80% or more. The haze may be 20% or more, 30% or more, 40% or more, or 50% or more. When these are measured, the measurement may be performed on a portion other than a portion where characters or figures are printed as described later.

Any color can be used for the outer bag 31 as long as it has translucency and light diffusing properties. Also, the outer bag 31 may display characters, graphics, or the like. These characters and figures may be printed on the outer bag, or may be drawn or pasted. Since the bag-shaped chemiluminescent material of the present invention can be made flat without gas when not in use, it is also suitable for the user to draw arbitrary letters, figures, and the like. Also, the shape of the outer bag 31 is a major part of the overall structure of the bag-shaped chemiluminescent material. The shape of the outer bag 31 may be rod-like, spherical, polygonal prism-like, or a combination of these, or an arbitrary three-dimensional shape in consideration of design. In particular, considering the ease of inflating and the ease of hitting each other during use, it is preferable to use a so-called stick balloon shape.

[Fixed parts 32, 33]
The bag-shaped chemiluminescent body 10 preferably has a fixing portion for fixing a portion of the enclosed chemiluminescent member 2 in the outer bag 31 . This fixing part may be one that fixes both ends of the chemiluminescent member 2 contained in the bag-shaped chemiluminescent body 10 like the fixing part 32 and the fixing part 33, and considering the usage mode, the fixing part 32 or Only a part of the chemiluminescent member 2 may be fixed such that only one of the fixing portions 33 is fixed. This fixation can be performed, for example, by welding, bonding with an adhesive, or fixing with a fixing member such as a clip.

[Introduction member 4, introduction port 41]
The bag-shaped chemiluminescent body 10 has an introduction member 4 . The introduction member 4 has a structure that forms an introduction portion for introducing fluid into the outer bag 31 from the outside of the bag-shaped chemiluminescent body 10 . The fluid introduced here may be gas or liquid. Preferably, the introduced fluid is a gas. By introducing the gas, the bag-shaped chemiluminescent body 10 becomes lightweight, and a large-sized bag-shaped chemiluminescent body with excellent handleability can be obtained. As the gas, air, exhaled breath, helium gas, and the like, which are used when inflating various balloons, are preferably used.

Examples of the structure of the introduction portion include a structure having an introduction port 41 like the introduction member 4, or an opening portion such as a cut portion provided in the welded portion of the outer bag 31 or the like, and the fluid is introduced into the straw through this opening portion. The space 34 of the outer bag 31 can be filled with the fluid at the time of use by pouring the fluid in by a method such as blowing in using an appropriate air supply means such as. It is preferable that the introduction member 4 serving as the introduction portion has a check valve. By providing the check valve, it is possible to prevent leakage of the fluid poured into the outer bag 31 during use. As the check valve, various structures that are used as a check valve for fluid can be used.

The introduction port 41 of the introduction member 4 may be used as a discharge port for discharging the fluid using discharge means after using the bag-shaped chemiluminescent body 10 . For example, in the case of a structure in which a straw is inserted and inflated by exhalation, the check valve may be maintained in an open state by inserting the straw, and the exhaust may be discharged through the straw. By using an introduction member that can perform such exhaust, the fluid filling the space 34 of the bag-shaped chemiluminescent body 10 can be removed quickly after use, and the volume of the bag-shaped chemiluminescent body 10 can be reduced. can be stored, moved, disposed of, etc.

The bag-like chemiluminescent material may be provided with a handle so that a person can easily hold it, a through-hole part so that a plurality of items can be easily connected, or a decoration.

Since the bag-shaped chemiluminescent material is in a state in which the chemiluminescent composition is widely and uniformly spread inside, the entire bag-shaped chemiluminescent body can emit light. In addition, even if the bag-shaped chemiluminescent bodies are collided with each other or hit with a hand or an object in order to make a sound in the inflated state, the flexibility of the filled fluid and the outer bag acts as a buffer, and the inner bag is contained. It is also possible to prevent leakage of the chemiluminescent material, etc., which is present, and is suitable for ease of handling and flexibility as a toy. The bag-shaped chemiluminescent material according to the present invention can be used as stick balloons, lighting, toys, indicator lights, advertising balloons, and the like.
