Description

The present invention relates to chemiluminescent materials.

Traditionally, chemiluminescent fluorescent liquids and chemiluminescent materials have been used, 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 or solids, such as a combination of oxidants for use, are widely used (Patent Documents 1 and 2).

As shown in Patent Documents 1 and 2 described above, these chemical illuminants are further provided with an inner cylinder such as a glass ampoule inside a tubular container (inside an outer case), and one of the liquids (or solids) is used. The inner cylinder is filled, the other liquid is filled outside the inner cylinder and the outer case is filled, and at the time of storage, two kinds of liquids are separated by the inner cylinder (glass in the case of a glass ampoule). It has been proposed and used as a configuration in which an inner cylinder is broken by bending a chemical luminescent material at the time of use, and two kinds of liquids (or liquids and solids) are mixed to generate chemical luminescence in a tubular container.

Patent Document 3 discloses a chemiluminescent material having a spacer arranged substantially in the center of the outer case, as a chemiluminescent material that is lightweight even if the size is increased.

Japanese Patent No. 4044934 Japanese Unexamined Patent Publication No. 8-280421 Japanese Patent No. 6138743

As disclosed in the above-mentioned patent documents and the like, various chemiluminescent materials having a shape such as a columnar shape are disclosed. These chemiluminescent substances contain an ampoule, a liquid of the chemiluminescent composition, or the like in the cylinder (outer case).
If the chemiluminescent cylinder is overfilled with the chemiluminescent composition liquid, the gas (CO ₂ ) generated when the chemiluminescent reaction occurs may deform the outer case and cause liquid leakage. In addition, when sealing with a lid, there is a risk of reaction due to liquid leakage or heat of melting. In addition, there is a risk of deformation or liquid leakage due to changes in internal pressure due to evaporation of the solvent in the chemiluminescent material due to temperature differences or the like. Therefore, the chemiluminescent body is not filled with the composition or the like to the vicinity of the capacity limit, and the content (liquid amount) or the like is adjusted so that the capacity is sufficient.
On the other hand, in the chemiluminescent body, the chemiluminescent composition emits light at a certain place. That is, the height of the volume (liquid level, etc.) of the chemiluminescent composition in the outer case of the chemiluminescent substance is the light emitting range. If there was a space in the chemiluminescent container that was not filled with liquid, the space was not emitting light, so the light emitting area was limited. Under such circumstances, it is an object of the present invention to provide a chemiluminescent material having a wider light emitting area.

It is not limited to the contents of. In addition, when the expression "-" is used in this specification, it is used as an expression including numerical values before and after it.

[First Embodiment]
1 to 3 show the first embodiment of the chemiluminescent material of the present invention. FIG. 1 is a perspective view showing the overall structure of the chemiluminescent material 100. The chemiluminescent material 100 has an outer case 1, a liquid absorbing material 2, an ampoule 3, and a spacer 4. The liquid absorbing material 2, the ampoule 3, and the spacer 4 are housed in the outer case 1, and both ends of the outer case 1 are sealed by the lids 11 and 12, respectively.

FIG. 2 is a cross-sectional view taken along the line AA of the chemiluminescent material 100 shown in FIG. FIG. 3 is a partially enlarged schematic cross-sectional view when the lid portion 11 of the chemiluminescent material 100 shown in FIG. 1 is on the upper side. The ampoule 3 is fitted into the groove 41 of the spacer 4. The ampoule 3 contains the first chemiluminescent composition 5. A space 7 is formed between the spacer 4 and the ampoule 3 and the outer case 1. In the space 7, the liquid absorbing material 2 is provided along the periphery of the spacer 4 and the ampoule 3. The second chemiluminescent composition 6 is housed in the space 7, and the second chemiluminescent composition 6 is absorbed and held by the liquid absorbing material 2 and exceeds the amount of liquid absorbed by the liquid absorbing material 2. Things can flow in space 7. The liquid absorbing material 2 is arranged in this space 7 and is arranged along the inner peripheral surface of the outer case 1 having a cylindrical shape.

The chemiluminescent material 100 can be manufactured, for example, as follows. The lid portion 12 is provided on the outer case 1 and welded, and the side of the outer case 1 on which the lid portion 11 is provided is opened. From this open side, the sheet of the liquid absorbing material 2 is inserted so as to be arranged along the inner circumference of the outer case 1. Next, the spacer 4 is inserted from the opened side so as to be arranged substantially in the center of the outer case 1. Next, the ampoule 3 in which the first chemiluminescent composition 5 is previously contained and sealed is inserted into the groove portion of the spacer 4. Next, the second chemiluminescent composition 6 is poured into the gap between the spacer 4 and the outer case 1. After that, the lid portion 11 is welded to the outer case 1. As a result, the chemiluminescent material 100 is manufactured. In the chemiluminescent material 100, the second chemiluminescent composition 6 is sucked into the liquid absorbing material 2 inside the outer case 1, and the chemiluminescent material 100 is shaken to cover the entire chemiluminescent material 2. The second chemiluminescent composition 6 is impregnated.

At the time of use, the ampoule 3 was broken by pushing the position where the ampoule 3 was arranged from the outside of the outer case 1 or applying a bending force to the entire chemiluminescent material 100, and the first ampoule 3 was housed in the ampoule 3. The chemiluminescent composition 5 is released into the space 7 in the outer case 1. When the first chemiluminescent composition 5 (for example, a chemiluminescent oxidizing solution) comes into contact with the second chemiluminescent composition 6 (for example, a chemiluminescent fluorescent solution), chemiluminescence is generated. The second chemiluminescent composition 6 is in a state of being absorbed by the entire liquid absorbing material 2, and when the chemiluminescent material 100 is shaken, the first chemiluminescent composition 5 spreads in the outer case 1. Chemiluminescence is generated in the entire portion where the liquid absorbing material 2 is arranged. Therefore, the chemiluminescent material 100 appears to emit light uniformly from one end to the other. In the conventional case, the chemiluminescent composition gathers at the lower part of the cylinder and emits light more widely than the one that emits light only in that range.

[Second embodiment]
4-9 show a second embodiment of the chemiluminescent material of the present invention. FIG. 4 is a front view showing the overall structure of the chemiluminescent material 101. The chemiluminescent material 101 has an outer case 1, a liquid absorbing material 2, an ampoule 31, an ampoule 32 (FIG. 6), and an ampoule holding member 8. The liquid absorbing material 2 and the ampoule holding member 8 are housed in the outer case 1, and the ampoule 31 and the ampoule 32 are held by the ampoule holding member 8. Both ends of the outer case 1 are sealed by lids 11 and 12, respectively.

FIG. 5 is a diagram for explaining details of the ampoule holding member 8 used in the chemiluminescent material 101. FIG. 5A is a front view of the ampoule holding member 8. FIG. 5B is a plan view of the ampoule holding member 8. FIG. 5C is a perspective view of the ampoule holding member 8. FIG. 5 (d) is a cross-sectional view taken along the line BB (FIG. 5 (b)) of the ampoule holding member 8.

The ampoule holding member 8 has a fixing portion 81 and an ampoule holding portion 82, and the ampoule holding portion 82 is connected to the fixing portion 81 by a flexible connecting portion 83. Further, the ampoule holding member 8 has an ampoule fixing portion 84 and a connecting portion 85 for connecting the ampoule fixing portion 84 and the fixing portion 81. The ampoule holding member 8 can hold two ampoules, the first ampoule is arranged between the ampoule holding portion 821 and the ampoule fixing portion 841, and the second ampoule is arranged from the ampoule holding portion 822 to the ampoule fixing portion 842. Placed in between. In the chemiluminescent material 101, the ampoule holding member 8 is arranged such that the fixing portion 81 is in contact with the liquid absorbing material 2 and is further close to the outer case 1. The ampoule holding member 8 can be bent around the flexible connecting portion 83 by pushing the ampoule holding portion 82 in the upward direction in FIG. 5A while the fixing portion 81 is fixed. The ampoule holding portion 82 and the flexible connecting portion 83 form a flexible holding portion that is flexible in the direction of the fixing portion 81. The ampoule holding member 8 has a structure in which a portion of the chemiluminescent material 101 to be a lid portion 11 is integrally molded.

FIG. 6 shows a state in which the ampoule holding member 8 holds the ampoule 31 and the ampoule 32. The ampoule 31 contains the first chemiluminescent composition 51, and the ampoule 32 contains the second chemiluminescent composition 61.

In FIG. 7, the liquid absorbing material 2 is arranged along the inner circumference of the outer case 1 with the lid portion 12 provided on the outer case 1 and one end closed, and FIG. 6 is shown from the open end side of the outer case 1. It is a figure explaining the process of inserting an ampoule holding member 8 holding an ampoule 31 and 32 as shown in. The chemiluminescent material 101 can be manufactured by fully inserting the ampoule holding member 8 and closing the lid portion 11.

FIG. 8 is a schematic front view for explaining an operation when the chemiluminescent material 101 is used. FIG. 8A is a schematic front view for explaining the pressing position 14 and the like when the chemiluminescent material 101 is used. FIG. 8B is a diagram for explaining a state in which the ampoule 31 is broken by pressing.

As shown in FIG. 8A, the pressing position 14 of the ampoule 31 separated from the fixing portion 81 of the ampoule holding member 8 is pressed and used. The pressing position 14 is located on the side of the outer case 1 and is a portion where the ampoule holding portion 82 is close to the inside thereof. The ampoule 31 contains the first chemiluminescent composition 51. By simply pushing the pressing position 14 in the pressing direction P1, the outer case 1 is slightly recessed in the vicinity of the pressing position 14. Due to this recess, the ampoule holding portion 82 is bent in the direction of the fixing portion 81 around the flexible connecting portion 83.

A bending force is applied to the ampoule 31 being held in accordance with the bending of the ampoule holding portion 82. The ampoule 31 is formed of an ampoule made of glass or the like that is easily broken by a bending force, and the bending force causes an ampoule breaking portion 311 near the flexible connecting portion 83 (FIG. 8 (b)). Then, the first chemiluminescent composition 51 contained in the ampoule 31 is discharged from the ampoule breaking portion 311 into the space 71 in the outer case 1 as the discharge liquid 511.
Although the ampoule 31 has been mainly described here, the ampoule 32 held by the ampoule holding member 8 is similarly broken, and the second chemiluminescent composition 61 contained therein is similarly released.

The first chemiluminescent composition 51 emitted from the ampoule 31 and the second chemiluminescent composition 61 emitted from the ampoule 32 are appropriately mixed in the space 71 in the outer case 1, and further. Each liquid or mixed liquid is absorbed by the liquid absorbing material 2. By shaking the chemiluminescent material 101, the mixture or the like is agitated in the space inside the outer case 1, and the liquid is appropriately absorbed by the liquid absorbing material 2, and chemiluminescence is generated in the entire portion where the liquid absorbing material 2 is arranged. It becomes a thing. The chemiluminescent material 101 according to this second embodiment can start chemiluminescence only by pressing the pressing position 14 as described above. That is, it is an excellent structure that can quickly start chemiluminescence with one hand. It is also excellent in that multiple ampoules can be broken at the same time.

The outer case 1 is generally molded using a thermoplastic resin composition or the like. Therefore, it has a small amount of air permeability, and the chemiluminescent composition contained therein may deteriorate during long-term storage. In order to avoid this deterioration, it is conceivable that both chemiluminescent compositions are contained in a glass ampoule having a higher airtightness during storage. In the chemiluminescent material having the conventional structure, since the internal volume (liquid level) of the chemiluminescent material is the light emitting area, it is better to increase the internal volume as much as possible. However, as the amount of liquid increases, it becomes heavier when the chemiluminescent material is enlarged. Further, when two glass ampoules are used, the amount of liquid that can be accommodated in the glass ampoule is limited, the internal capacity is reduced, and the light emitting area is reduced. However, by arranging the liquid absorbing material 2 as in the present invention, even with a chemiluminescent composition having a small amount of content (liquid amount), the chemiluminescent composition can be efficiently developed over the entire chemiluminescent material. Since the chemiluminescent state is maintained, the chemiluminescent material can be made into a lightweight chemiluminescent material having a wide light emitting area.

Based on this embodiment, for example, the following chemiluminescent material can be produced.
-Outer case 1: Outer diameter φ30 mm (thickness 0.7 mm), length 20 cm, made of PP resin composition-Cover 12: A lid made of PP resin composition was used with a size that fits inside the outer case. ..
-Liquid absorbing material 2: Non-woven fabric sheet made of PP resin composition (thickness 150 μm), arranged by winding along the inner wall of the outer case.
・ Ampoules 31, 32: Glass ampoules Contents 30 mL
The first chemiluminescent composition 51: 80 parts by mass of tributyl acetylcitrate and 20 parts by mass of benzoic acid were mixed to prepare a solvent (1). A composition that functions as a fluorescent liquid is prepared using CPPO, which is an oxalic acid ester, at 0.164 mol / L, a fluorescent agent at 3.27 mmol / L, and the balance as the solvent (1), and is filled in an ampoule 31 for use. board.
-Second chemiluminescent composition 61: 70 parts by mass of dimethyl phthalate and 30 parts by mass of diethylene glycol monoethyl ether were mixed to prepare a solvent (2). A composition functioning as an oxidizing solution was prepared using 3% by mass of hydrogen peroxide, 0.7 mmol / L of sodium salicylate, and the balance as the solvent (2), and used by filling the ampoule 32.
Ampoule holding member 8: As the ampoule holding member 8, the ampoule holding member 8 has a fixing portion 81 in contact with the inner wall of the outer case at the center of the outer case, and the flexible connecting portion 83 is arranged in the center of the outer case. An ampoule holding member 8 having an ampoule holding portion 82 extending from the lid portion 12 to the lid portion 12 side by 50 mm and capable of holding the ampoule was manufactured from a PP resin composition. The ampoule holding member 8 is integrally molded with the lid portion 11.
-Manufacture of chemiluminescent material: A chemiluminescent material was produced using these members and the like. This chemiluminescent material is light because it contains a composition for chemiluminescence in a very small amount with respect to the maximum content of the outer case. It emitted light uniformly.

(Modified example of the second embodiment)
In the second embodiment, an example is described in which two ampoules are used to accommodate the first chemiluminescent composition and the second chemiluminescent composition, respectively. The first chemiluminescent composition and the second chemiluminescent composition use only one ampoule with one liquid in the ampoule and the other liquid as in the first embodiment. It may be in the form of being housed in the outer case and outside the ampoule.

(External case 1)
The chemiluminescent material of the present invention has an outer case in which both ends are sealed. The inside of the outer case and the outside of the ampoule contained in the outer case may be filled with one of the chemiluminescent compositions. The outer case has a single hollow space extending in the length direction of the outer case.
The outer case is generally a resin container, and this container is molded by a resin molding method such as injection molding using resin. As this resin, a resin mainly composed of polyethylene (PE), polypropylene (PP) or the like is generally used from the viewpoints of heat resistance, solvent resistance and mechanical strength. For example, in the case of polypropylene, a polypropylene resin composition to which an additive is appropriately added is commercially available, and a container manufactured by such a resin composition is a chemiluminescent material made of a resin composition using polypropylene as a resin. It becomes the outer case of.
Further, in order to improve the dispersibility of light due to chemiluminescence inside the chemiluminescent material during use, a light dispersant is appropriately added to the resin composition, or a colorant is mixed to change the color tone to manufacture an outer case. You may.
Further, the container may be a container having high light dispersibility in a cloudy state by controlling the crystallinity by controlling the production conditions.

(Molding of outer case)
The outer case of the present invention is made of resin as described above. Here, the outer case becomes an outer case that is sealed by a predetermined method after adding an ampoule, a chemical composition for chemiluminescence, or the like to the inside of the outer case. As a typical method of this sealing method, there is a method of attaching a lid portion that closes the cross section of the container to the main body container for the outer case, and as a specific method of attaching the lid portion, the lid portion by heat welding is used. There is a method of attaching. When attaching the lid portion, a space for attaching the lid portion is provided in the main body container for the outer case. Further, it is preferable that the lid portion has a columnar outer case so that heat welding or the like can be easily performed, and the welded portion has a structure that facilitates welding so as to be the circumferential portion thereof.

The outer case may have an arbitrary shape according to the use of the chemiluminescent material, but a cylindrical shape, a columnar shape, a substantially rectangular parallelepiped shape, or the like can be used. Since the chemiluminescent material of the present invention can obtain a wide light emitting area even if the amount of liquid to be accommodated is small, the chemiluminescent material having a wide light emitting area can be designed by increasing the diameter or length. Suitable for. This light emitting area also depends on the size of this outer case. Further, the outer case may be provided with a connecting portion that can be connected to another member such as a screwed portion or a locking portion such as a clip. When having such a connecting portion, it becomes easy to use in a wider range of applications in combination with other members having the connected portion.

The specific size of the outer case can be, for example, 20 mmφ to 40 mmφ or 28 mmφ to 32 mmφ when converted to the equivalent of a circle in the cross section. Further, for example, the lower limit of the length may be 100 mm or more, 150 mm or more, 180 mm or more, and the upper limit of the length may be 500 mm or less, 400 mm or less, or 300 mm or less. Further, the thickness of the cylinder of the outer case is appropriately set within a range in which sufficient mechanical strength and liquid leakage can be prevented as a chemiluminescent material, and at the same time, the internal ampoule or the like can be pressed or bent to break. As a specific thickness, the lower limit thereof is preferably 0.4 mm or more, and may be 0.5 mm or more or 0.6 mm or more. The upper limit of the thickness is preferably 1.5 mm or less, and may be 1.2 mm or less or 1.0 mm or less.

(Liquid absorbent 2)
The chemiluminescent material of the present invention has a liquid absorbing material arranged inside the outer case. This liquid absorbing material absorbs the chemiluminescent composition. The liquid absorbing material absorbs the chemiluminescent composition and becomes a light emitting surface at the time of chemiluminescence. A porous sheet or the like can be used as the liquid absorbing material. A porous sheet is a sheet having a large number of pores. 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. A porous sheet having a thickness of about 30 μm or more is used, and the lower limit of the thickness may be 50 μm or more, 80 μm or more, or 100 μm or more as appropriate according to the use of the chemiluminescent material. Further, as the upper limit of the thickness, those having a thickness of 2 mm or less, 1 mm or less, and 500 μm or less are used as appropriate. The liquid absorbing material can also be arranged on the surface in contact with the lid portion, and the light emitting area can be expanded.

The liquid absorbing material may be in a state of not absorbing liquid when it is not in use, as long as it can absorb any of the liquid chemiluminescent compositions during chemiluminescence. The chemiluminescent material absorbs any of the chemiluminescent compositions, and permeates, holds, and supports the chemiluminescent composition in various states such as powdery, liquid, and high-viscosity liquids such as gel. You may let me. The liquid absorbing material preferably has a permeation / retention property of the chemiluminescent composition and a certain shape retention property (mechanical strength) for maintaining the shape in the outer case of the chemiluminescent material. Further, it is preferable that the compound used in the chemiluminescent composition, particularly a solvent, has a certain resistance and is not easily decomposed even if it comes into contact with those compounds. For this purpose, a composite nonwoven fabric in which a plurality of materials are combined may be used as appropriate.

The liquid absorbing material may carry any one selected from the group consisting of oxalic acid ester, catalyst and fluorescent agent. These components may be individually supported on powder, or may be supported as a slurry by impregnating it with a liquid absorbing material and drying it to volatilize a dispersion medium or the like of the slurry. .. By supporting in this way, the component that contributes to chemiluminescence can be directly supported on the liquid absorbing material at a high concentration, and the emission intensity can be improved. In addition, the portion of the liquid absorbing material on which these components are supported tends to emit light.

This liquid absorbing material is arranged inside according to the shape of the outer case of the chemiluminescent material. It is preferable that this arrangement is arranged so that the arrangement position of the liquid absorbing material is as wide as possible. With such a configuration, it is possible to prevent the composition from accumulating on the lower side in the vertical direction in the chemiluminescent material, and it is possible to provide a wide and uniform light emitting portion in the entire chemiluminescent material.
In order to stabilize the chemiluminescent material in the outer case, the outer case and the liquid absorbing material can be bonded to each other at a plurality of places by heat welding, an adhesive or the like. This adhesion may be performed with the lid of the outer case or the like. This makes it possible to prevent the liquid absorbing material from moving or peeling off the chemiluminescent material in the outer case.

The liquid absorbing material to be arranged may be arranged so as to have a plurality of layers in the outer case. That is, a plurality of liquid absorbing materials may be arranged, or one liquid absorbing material may be bent and arranged so as to form a plurality of layers. By arranging so as to have a plurality of layers, the liquid absorption amount of each layer (sheet) is controlled to adjust the light emission, the chemiluminescent composition is sandwiched between the layers and supported, or the liquid absorption material is supported. It is also possible to make a design such as improving the mechanical strength of the product. Further, by arranging the layers as a plurality of layers, the internal structure inside the chemiluminescent substance becomes more difficult to see, so that the design is excellent in that only the chemiluminescent light is recognized as a whole.

The liquid absorbing material may be provided with characters, figures, patterns, or the like. As mentioned above, a porous sheet or the like is partially used as the liquid absorbing material. Generally, the outer case used for the chemiluminescent material is a polyolefin-based material, particularly polypropylene resin or the like. If this polypropylene resin or the like is in a state of high smoothness like a container, it may be difficult to print characters, figures, or the like. In addition, since the characters and figures are outside the light emitted inside the chemiluminescent material, the light emission is blocked. However, if characters, figures, or the like are provided on the liquid absorbing material, printing or the like becomes easy due to the space between fibers such as a porous sheet. Further, the liquid absorbing material may be impregnated with a fluorescent agent at least a part thereof. It is in a state of being microscopically adjacent to the chemiluminescent composition, and the chemiluminescent composition between the outer case and the liquid absorbing material emits light, and the printing of the liquid absorbing material can be arranged so as to be illuminated by the light. Therefore, the effect of being displayed brightly can also be obtained. This printing or the like can be performed with various dyes, pigments and the like. In particular, in order to utilize the light of chemiluminescence, it is preferable to use an ink containing a fluorescent agent, and the fluorescent agent is supported on the liquid absorbing material. These fluorescent agents may be common to the fluorescent material of the chemiluminescent composition, and other phosphorescent agents and the like may be used.

(Ampule 3 (31, 32))
When not in use (during storage, etc.), the chemiluminescent material of the present invention is separated by an ampoule contained in an outer case of the chemiluminescent material so that the two chemiluminescent compositions are not mixed. It can be the inside of the outer case and the outside of the ampoule filled with one of the chemiluminescent compositions. Alternatively, two or more ampoules containing a pair of chemiluminescent compositions may be used. The number of ampoules may be three or more by separately providing a composition containing a plurality of dyes.
One of the paired chemiluminescent compositions is contained inside the ampoule. For example, the ampoule is filled with either a fluorescent liquid or an oxidizing liquid, and the outer case is filled with the other liquid, or different ampoules are filled with the fluorescent liquid and the oxidizing liquid, respectively, and sealed. There is.

This ampoule may be any ampoule that breaks in the outer case when a bending force is applied, and a glass ampoule is generally used. This is because the glass makes it possible to block the mixing of the external liquid and the internal liquid when not in use, and further, the force applied to the chemiluminescent material makes it appropriately fragile. It should be noted that the force applied to the chemiluminescent material is sufficient if the ampoule is bent to the extent that it breaks, and especially when the ampoule is made of glass, the bending is such that a gentle curve is drawn. It's fine. Furthermore, by using the ampoule holding member, it is possible to easily break the ampoule with one hand with a slight dent that is weaker than bending and is about a pressure on the outer case.

(Spacer 4)
The chemiluminescent material of the present invention may be provided with a spacer inside the outer case. Since it is easy to reduce the weight as a whole by providing a spacer, it is suitable for designing a chemiluminescent material having a wide light emitting area by increasing the diameter or length.

Further, the chemiluminescent material of the present invention is a spacer arranged substantially in the center of the outer case, has a holding portion for accommodating an ampoule on the outer edge of the spacer, and is arranged substantially in the center of the outer case. This makes it possible to have a spacer that creates a gap (space) between the outer case and the spacer in which the chemiluminescent composition is filled. With this spacer, the amount of chemiluminescent composition contained in the outer case can be reduced. Further, by accommodating the ampoule in the holding portion provided on the spacer, the ampoule can be stably held.

When the spacer is used, one of the chemiluminescent compositions can be filled in the gap (space) formed between the spacer and the outer case, and one of the chemiluminescent compositions filled in the gap can be filled. When the composition of the above reacts with the other composition in the ample when it breaks, it chemically emits light and emits light in the outer case of the chemiluminescent material. At this time, the portion corresponding to the outer peripheral portion of the outer case of the chemiluminescent material becomes the light emitting surface, and the spacer has substantially the same axis as the outer case in the center so that the entire circumferential direction of the outer peripheral portion of the chemiluminescent material can easily emit light almost uniformly. It is preferable to provide the chemiluminescent material in the gap between the spacer and the outer case so that the chemiluminescent surface can be obtained on the outer peripheral portion of the chemiluminescent material. The gap generated between the spacer and the outer case can be, for example, a gap of about 0.3 mm to 5 mm.

The spacer may have a holding on its outer edge that houses the ampoule. This holding portion can be achieved in the shape of a groove provided along the length direction of the spacer. The ampoule can be accommodated so as to be fitted in this groove. By holding the ampoule in this holding part, it protects the internal ampoule from breaking when not in use, while it can be easily broken by applying a light bending force during use. , Can be an easy-to-use chemiluminescent material. It is preferable that the spacer is provided with two or more and five or less holding portions for accommodating the ampoules provided in the spacer. The chemiluminescent material of the present invention has a preferable shape when a chemiluminescent material having a large diameter is obtained. Therefore, the chemiluminescent composition, especially the chemiluminescent composition in the ampoule after breaking the ampoule, is easily released and mixed at a plurality of positions on the outer edge along the wide outer peripheral surface. Is preferably provided. In addition, such an arrangement can provide a well-balanced aesthetic and a sense of weight.

In the present invention, by adopting this spacer having a lighter specific gravity than that of the chemiluminescent composition, it is possible to contribute to the weight reduction of the entire chemiluminescent material. Further, by using a material that does not absorb the chemiluminescent composition, the amount of the chemiluminescent composition contained in the spacer is reduced, so that the weight can be further reduced. Further, by using a white substance having high light scattering property as a spacer, the change in the color of the luminescence due to the chemiluminescent composition that emits light without a chemiluminescent substance at the time of use is reduced, and the light loss is reduced to the outside. It is expected to scatter and achieve high brightness. From this point of view, the spacer is preferably a foam made of foamed resin. Further, it is preferable that the spacer also has solvent resistance to a solvent or the like used in the chemiluminescent composition. As such a spacer, it is preferable to use a foam made of a foamed resin of polyethylene (PE) and / or polypropylene (PP).

(First chemiluminescent composition 5 (51), second chemiluminescent composition 6 (61))
The present invention relates to a chemiluminescent material that produces chemiluminescence by mixing two types of chemiluminescent compositions. Here, the two types of compositions that generate chemiluminescence by mixing are, for example, a chemiluminescent fluorescent solution (a oxalate ester and a dye (fluorescent substance), a solvent, etc.) and a chemiluminescent oxidizing solution (peroxidation). Generally, liquids such as oxidants such as hydrogen water and catalyst components, solvents, etc.), but liquids that generate chemiluminescence when mixed in the same manner as these liquids, or powders or granules. Various chemiluminescent compositions can be used, such as solid ones. In the present application, one of them may be referred to as a first chemiluminescent composition, and the other may be referred to as a second chemiluminescent composition. When both of these compositions are liquid, they are excellent in mixing properties and are preferable because they tend to rapidly generate uniform light emission as a whole.
Those that generate chemiluminescence by mixing here are generally prepared as compositions of a plurality of compounds, etc., but in the present invention, those that can be used as a single substance are also available. Including, it is referred to as a composition.

In the present invention, as partially described above, the liquid absorbing material may carry at least one component selected from the group consisting of an oxalic acid ester, a catalyst, and a fluorescent substance. These components are used as components constituting the chemiluminescent composition.
Examples of the oxalic acid ester include CPPO (Bis (2,4,5-trichloro-6-carbopentoxyphenyl) oxalate: bis (2,4,5-trichloro-6-carbopentoxyphenyl) oxalate) and CIPO (Bis). [3,4,6-trichloro-2- (3-methylbutyloxycarbonyl) pheny] oxalate: bis [3,4,6-trichloro-2- (3-methylbutyloxycarbonyl) phenyl] oxalate) and the like can be used. These oxalic acid esters may be supported as an oxalic acid composition. The oxalic acid composition contains an oxalic acid ester and the like, and can be used as a composition for chemiluminescence, and is a composition mainly containing an oxalic acid ester. For example, among the compositions, those containing 50% by mass or more, 80% by mass or more, and 90% by mass or more of oxalic acid ester can be used, and the concept includes those composed of oxalic acid esters. Since the oxalic acid ester itself is solid at room temperature, it can be supported by being in contact with the liquid absorbing material in the form of powder or by appropriately dispersing it with a solvent or the like. As the other component, a composition in which a solvent, a catalyst, a dye and the like are mixed may be used.

As the catalyst, one that can be used as a catalyst for chemical luminescence can be appropriately used, and salicylic acid such as lithium salicylate, ammonium salicylate, sodium salicylate, and tetraalkylammonium salicylate salt and derivatives thereof, tetrabutylammonium salicylate (TBAS), and benzoic acid can be used. Sodium acid acid and the like can be used. Usually, it is contained in an amount of about 0.1 mmol / L to 10 mmol / L with respect to the oxidizing liquid used in the chemiluminescent composition, and an amount corresponding to that amount as a chemiluminescent material may be supported on the liquid absorbing material.

The fluorescent substance is not particularly limited as long as it has a spectral emission in the range of 300 to 1200 nm and is at least partially soluble in the oxidizing solution solvent. Examples of these fluorescent compounds include fused rings such as anthracene, substituted anthracene, benzoanthracene, phenanthrene, substituted phenanthrene, naphthacene, substituted naphthacene, pentacene, substituted pentacene, perylene, substituted perylene, biolantron, substituted biolantron, naphthalimide, and substituted naphthalimide. Phenanthrene aromatic compounds having the above are exemplified. The substituent of the above compound is not particularly limited as long as it does not interfere with the luminescence reaction, and examples thereof include a phenyl group, a lower alkyl group, a chloro group, a bromo group, a cyano group, an alkoxy group and a phenylnaphthyl group. The guideline for the concentration of the fluorescent substance in the chemiluminescent composition (fluorescent liquid) is about 0.01 to 5% by mass, which is set according to the luminescence performance such as color, intensity, and time, and the mixing property, and is used as a chemiluminescent substance. A corresponding amount may be supported on the liquid absorbing material.

In the present invention, the chemiluminescent composition may be used as a high-viscosity chemical composition. The high-viscosity chemical composition is one in which the viscosity is increased by containing a thickener in the first chemical composition. Taking an oxidation composition for chemical emission as an example, a mixture of a hydrogen peroxide solution, an oxidizing agent, a catalyst and a solvent is used as a typical composition in the past, and it is a liquid having a low viscosity, and it is used as it is. You can also.

In the present invention, a thickener may be further added to the chemical composition to increase the viscosity, which improves the retention by the liquid absorbing material and makes it difficult for the chemiluminescent material to settle. The thickener used in the high-viscosity chemical composition is not particularly limited as long as it can obtain an arbitrary viscosity, and a thickener that does not significantly deteriorate components such as a solvent used in the high-viscosity chemical composition is used. It can be selected as appropriate. Examples of this thickener include wax, ultra-low molecular weight polyethylene, petrolatum substances, paraffin, polymers, fumed silica and the like. Further examples of suitable thickeners are from polymeric thickeners such as polyamides, vinyl chloride resins, polystyrene, and polyacrylates, rubber modifiers, rubbers, starches, edible gels, polyacrylamide and fumed silica. One or more substances selected from the group can be used. Further, these thickeners can also be used in combination as appropriate. Among these, it is preferable to use fumed silica.

(Ampoule holding member 8)
The chemiluminescent material of the present invention may have an ampoule holding member. This ampoule holding member has a fixing portion for fixing a part of the ampoule in the outer case. That is, a part of the ampoule is fixed in a predetermined position in the outer case by the ampoule holding member. Then, by pressing the position of the outer case corresponding to the pressing position of the ampoule away from the fixed portion, an action point corresponding to the positional relationship is generated in the ampoule with the fixed portion as a fulcrum and the pressing position as a force point. From this point of action, the ampoule breaks due to its stress and the chemiluminescent composition in the ampoule is released into the outer case. As the structure of the ampoule holding member, various structures capable of breaking the ampoule by pressing the outer case can be adopted. For example, the ampoule holding member may have a fixing portion for fixing both ends of the ampoule in the outer case, and the ampoule may be arranged at a position close to the inner wall of the outer case. At this time, when the vicinity of the center of the ampoule near the inner wall of the outer case is pressed from the outside of the outer case, both ends of the ampoule are fixed and serve as fulcrums, and the ampoule is easily deformed by pressing. You can break an ampoule with just one.

A suitable ampoule holding member configuration has a fixing portion for fixing a part of the ampoule in the outer case, and further holds the ampoule corresponding to the pressing position of the ampoule and is flexible in the direction of the fixing portion. It may have a flexible holding portion. When pressing the outer case to apply stress to the inner ampoule, it is difficult to break if the entire ampoule moves inside the outer case. Therefore, there is a fixed portion that restricts the movement of the ampoule in the direction opposite to the pressing position, and the movement of a part of the ampoule is suppressed there. On the other hand, the pressing position itself is pushed in by pressing and can be deformed with the flexible portion of the flexible holding portion as a base point. As a result, the fixed portion serves as a fulcrum, the pressing position serves as a force point, and the flexible portion of the flexible holding portion serves as an action point, so that the ampoule can be broken efficiently and stably. With such an ampoule holding member, it is possible to break the ampoule and emit light by simply pressing a predetermined position without bending the chemiluminescent material. In the conventional chemiluminescent material, both ends of the chemiluminescent material had to be grasped and bent with both hands, but the chemiluminescent material of the present invention can break an ampoule with one hand, for example, by pushing with the thumb of one hand.
The ampoule holding member may hold a plurality of ampoules at the same time. In this case, both of the paired chemiluminescent compositions can be contained in the ampoule, and degeneration during storage such as oxidative deterioration can be further prevented.

(Chemiluminescent material 100 (101))
The present invention is characterized by the structure of a chemiluminescent material that produces chemiluminescence by mixing two types of chemiluminescent compositions. The chemiluminescent material of the present invention has a configuration suitable particularly when it is desired to have a large diameter, and even as a chemiluminescent material having a diameter of, for example, 20 mm or more, preferably 30 mm or more in diameter, the weight as a whole is used. Can be made lighter. Further, the length thereof is also appropriately set according to the intended use, and can be designed, for example, to have a length of 4 inches or more. Since the liquid absorbing material is inside the outer case, the entire surface of the cylinder appears to emit light even if the amount of the chemiluminescent composition such as the oxidizing liquid and the fluorescent liquid is small.

Here, the amount of the chemiluminescent composition in the chemiluminescent material is such that the total amount (for example, the total amount of the oxidizing solution and the fluorescent solution) is 70% by volume or less with respect to the maximum content of the outer case. In addition, the upper limit of the proportion of the chemiluminescent composition may be set and designed. This upper limit may be 60% by volume or less, 50% by volume or less, or 40% by volume or less. In particular, by using a highly liquid-absorbent material, supporting a part of the chemiluminescent composition on the liquid-absorbent material, or using a spacer, the lower limit of the ratio occupied by this chemiluminescent composition is Although it is not particularly specified, a lower limit such as 1 volume% or more or 5 volume% or more may be set.

(Manufacturing process)
In producing the chemiluminescent material of the present invention, it suffices if the chemiluminescent material of the present invention can be obtained, and one of the liquid absorbing material and the chemiluminescent composition can be obtained from the open end side of the outer case having one end sealed. Add the structures required for each chemiluminescent material, such as the composition of the chemiluminescent material, the spacer, the ampoule holding member, and the ampoule containing the other composition of the chemiluminescent composition, in any order, and then seal the open end of the outer case. It can be manufactured by doing.
More specifically, for example, it can be produced by the following method. First, the outer case on the tube with both ends open is cut to a desired length. Next, a lid is welded to one end of the outer case to form a container-shaped outer case in which one end is open. Next, a chemiluminescent fluorescent solution is added to the outer case as one of the chemiluminescent compositions in a predetermined amount. Next, a spacer made of a solid PP foam provided with a groove that functions as a holding part for accommodating the ampoule and an ampoule holding member are arranged substantially in the center of the outer case to which the chemiluminescent fluorescent liquid is added. do. When the spacer is used, an ampoule containing the other composition of the chemiluminescent composition is placed in the holding portion of the spacer placed in the outer case. When using the ampoule holding member, the ampoule may be arranged in advance at a predetermined position of the ampoule holding member. After that, the open end is sealed by fitting and welding the lid portion that closes the cross section of the outer case. This makes it possible to produce a chemiluminescent material.

The chemiluminescent material produced by the above-mentioned manufacturing method or the like contains a composition such as a chemiluminescent liquid inside the chemiluminescent material, but has a shape in which the welded portion of the outer case containing all of them is easily welded. Therefore, it is highly safe at the time of manufacturing and the effect of preventing liquid leakage of the obtained product. Further, since the spacer has an ampoule holding portion, even when a plurality of ampoules are contained in an outer case, there is little risk of contact between the ampoules and the like, and it is possible to manufacture the spacer by a method in which defective products are less likely to occur. Further, since the ampoule holding member can also hold the ampoule in advance and suppress unintended movement, it is possible to prevent the ampoule from breaking and the like, and to manufacture the ampoule by a method in which defective products are less likely to occur.

The chemiluminescent material of the present invention can be used as a chemiluminescent material having a wide light emitting area in various applications such as concert lights, warning lights, indicator lights, etc., in which the chemiluminescent material has been conventionally used. Industrially useful.
