SUMMARY OF THE INVENTION Japanese Patent Laid-Open No. 57-1884
In the fuse for a pyrotechnic candle shown in 91, when the proportion of the flame coloring agent and the spark agent is increased, the unburned flame coloring agent and the spark agent cover the vegetable fibers, so that the burning of the vegetable fibers is insufficient. Therefore, the combustion residue may increase or the flame may go out, and continuous ignition of a plurality of candle wicks may not be performed reliably.
Further, when the amount of combustion residue increases, the combustion residue hangs down in such a manner that it sticks to the candle body, and this portion becomes a new combustion core and burns up, so that continuous ignition cannot be performed. In order to avoid such a situation, it is necessary to keep the ratio of the flame colorant and spark agent very low, and enjoy flames and sparks of remarkable colors only by adding a small ratio of flame colorant and spark agent. I couldn't do that. In addition, Japanese Unexamined Patent Publication No.
As shown in the auto-ignition candle shown in 8-49830, a thread formed by applying a starch paste, a chemical paste, or the like other than a nitrified cotton-based adhesive to a surface of a cotton thread, a staple thread, a synthetic thread, or the like, Continuous burning is difficult to continue, and the filament having metal powder such as aluminum, magnesium and iron adhered to its surface is burned by a small flame. When the filamentous material shown here is used for continuous ignition of an automatic ignition candle, the flame of the filamentous material itself is small, so that the candle may not be ignited reliably and may not be ignited. Further, the fire of the filament itself may be extinguished on the way, and it is difficult to continuously ignite the candle. Also,
In the igniter for candle ignition disclosed in JP-A-59-46420, since only a substance exhibiting a flame color reaction is attached, only a colored flame is observed, and it is not possible to enjoy a spark. Can not. Furthermore, since nitrocellulose mixed with a substance exhibiting a flame reaction is directly adhered to the filament, the unburned material of the substance exhibiting the flame reaction covers the filament and insufficient combustion of the filament causes a tail-like combustion. Residue may increase or the flame may extinguish. Further, there is no specific description about the method of manufacturing the squib. In addition, the fibrous body for sparking shown in Japanese Patent Application No. 11-111707 has a remarkable effect of producing fireworks which crack and burst, but when the interval between the candle burning cores to be ignited is large, the filament is not used. Since there is no support for the filament for fire, the filament for ignition is jumped up or down, and it is not possible to ignite the candle smoothly.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a squib and a method of manufacturing a squib for continuously igniting a plurality of candle wicks, and a method of igniting a candle. The tail-shaped combustion residue is small, safe, and even when the interval between candles to be ignited is wide, the candle can be ignited smoothly and you can enjoy sparks and colored flames It is an object of the present invention to provide a squib and a method for manufacturing the squib, and a method for igniting a candle, which have a high degree of visual appeal.

[0005]

That is, a first aspect of the present invention is a squib for continuously igniting a plurality of candle wicks, the squib comprising a filament containing nitrified cotton and a metal wire. A second aspect of the present invention is a igniter used for candle ignition according to the first aspect, wherein the igniter is at least a fireworks iron together with nitrified cotton. A squib used for candle ignition characterized by containing powder,
A third invention is a squib used for igniting the candle according to the second invention, wherein the squib comprises at least iron powder for fireworks in nitrified cotton in a surface layer thereof. A fourth aspect of the present invention is a squib used for ignition, and a fourth invention is a squib used for candle ignition according to the second invention and a method of manufacturing the squib, wherein the squib is composed of a filament and a metal wire. A candle characterized by impregnating or coating a filamentous body with a nitrified cotton solution and primary drying, then impregnating or applying a nitrified cotton solution in which iron powder for fireworks is dispersed, and then secondary drying. A fifth aspect of the present invention relates to a method of manufacturing a squib used for ignition and a squib used for igniting a candle. A fifth invention is to set a squib to continuously ignite a plurality of candle wicks and a metal wire supporting the squib. Base to be characterized in that it constitutes,
It is a candle ignition method.

[0006] In the squib used for candle ignition according to the present invention, since the squib is composed of a filament including nitrified cotton and a metal wire, the squib is formed along the metal wire. Burning proceeds. For this reason, even when the interval between the burning cores of the candles to be ignited is wide, the squib does not jump up or down, making it possible to burn smoothly and reliably ignite the candle, and to obtain a tail-like combustion residue. There is no worry about the flame going out. Further, since the metal wire is used as a component, the tensile strength is relatively high, so that not only the candle burning cores can be connected to each other but also can be stretched while being fixed to fixing means such as a hook. Using this technique, it is possible to install the device over a considerably long distance, and various designs can be easily represented by the flame of the squib. Further, if a thin wire made of a heat-resistant material is used for the metal wire, the metal wire remaining after the combustion of the squib is almost invisible, and the flame floating in the air moves to ignite the candle. To be observed. On the other hand, by using the metal wire having a relatively large diameter, it is possible to form a desired design, characters, etc., and to ignite the candle while expressing the desired design, characters, etc. with the flame of the squib. Further, in the squib containing the pyrotechnic iron powder, the squib is quickly burned by the burning of the nitrified cotton, and the pyrotechnic iron powder becomes fine sparks and gorgeously dances. Further, the combustion residue burns out while snuggling to the metal wire, the combustion residue does not hang down in a tail shape, and the tail-shaped combustion residue hangs down in such a manner as to cling to the candle body, and this portion becomes a new combustion core. There is no such thing as burning up. Furthermore, during the ignition for the continuous ignition of the candle, not only the flame does not extinguish but also the continuous ignition of the candle burning wick can be ensured, but also the tail-like combustion It is an excellent one that can produce a gorgeous effect with a high visual appeal, which has little residue and can also enjoy a flame of remarkable color.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a squib and a method for manufacturing a squib used for igniting a candle according to the present invention will be described in detail. The squib 1 used for the candle ignition of the present invention is composed of a filament 2 containing nitrified cotton 4 and a metal wire 3. The thread body 2 and the metal wire 3 may be configured inseparably, or may be configured by means such as winding, tangling, twisting, hooking, and partially bonding. Furthermore, the nitrified cotton 4
In addition, it is also possible to employ a configuration including the pyrotechnic iron powder 5, and in particular, a configuration including the pyrotechnic iron powder 5 in the nitrified cotton 4 on the surface layer of the squib 1. An example of a method for manufacturing the squib 1 including the pyrotechnic powder 5 in the nitrified cotton 4 in the surface layer of the squib 1 is a composite filament formed from the filament 2 and the metal wire 3. A method in which the body 6 is impregnated or coated with the nitrified cotton 4 solution, and is first dried, then impregnated or coated with the nitrified cotton 4 solution in which the pyrotechnic iron powder 5 is dispersed, and then subjected to secondary drying. There is. Further, as a novel candle ignition method shown in the present invention, there is a method in which a squib and a metal wire which is close to and supports the squib are set together at a place where the candle is to be ignited.

[0008] As an example of the filament 2 containing the nitrified cotton 4,
For example, a thread 2 is used in which a plurality of twisted yarns such as cellulosic natural fibers such as cotton and hemp are further bundled or twisted and nitrified by a conventional method. For example, a method of immersing in a mixed liquid such as a concentrated nitric acid-concentrated sulfuric acid mixed liquid or a fuming nitric acid-acetic anhydride mixed liquid at around normal temperature, thoroughly washing with water, and then drying is adopted. At this time, the filaments 2 having various nitrification degrees are obtained depending on the composition of the mixed solution. A filament having a high degree of nitrification has a high thermal power at the time of combustion and has a high burning speed, but has a low tensile strength as the filament 2 and a filament having a low nitrification degree has a low thermal power at the time of combustion and has a low burning rate. In view of the above, it is necessary to adjust the composition of the mixed liquid so that the tensile strength required for the filament 2 used for the squib 1 for continuously igniting a plurality of candle burning wicks can be secured. In order to use the filament 2 thus obtained for the squib 1, the degree of nitrification is usually from 6% to 1% of nitrogen.
The filament 2 having a degree of nitrification of about 2.5% can be used,
The filament 2 having a nitrification degree of about 10% to 12% of nitrogen is preferably used.

Other examples of the filament 2 containing the nitrified cotton 4 include cellulosic natural fibers such as cotton and hemp.
Nitrified cotton 4 obtained by dissolving nitrified cotton 4 in an organic solvent or the like in which a plurality of cellulose-based regenerated fibers such as rayon or synthetic fibers such as polyethylene or polypropylene are twisted or bundled.
A filament 2 impregnated or coated with a solution and dried is used. It should be noted that cellulosic natural fibers and regenerated fibers can be said to be fibers which easily burn completely. Among them, cotton and rayon are preferably used because they have a small combustion residue. Although the nitrification degree and the like are not particularly specified for the nitrified cotton 4 used here, in practice, the nitrogen content of 10.4 specified in JIS standard K6703.
Industrial nitrocellulose having a nitrification degree of about 7% to 12.2% is easily used and is preferably used. Examples of the organic solvent for dissolving the nitrified cotton 4 include ketones such as acetone and methyl ketone, esters such as methyl acetate and ethyl acetate, cellosolves such as methylsolve and ethylsolve, and alcohols such as methanol, alone or in combination. A plurality of solvents are mixed and used as a true solvent, and ethanol, isopropanol, butanol, or the like is used as a cosolvent. To adjust the solubility of the nitrified cotton 4, a diluent such as toluene or xylene may be used. Since these organic solvents have different properties such as solubility and boiling point with the nitrified cotton 4, they may be appropriately selected and used depending on conditions such as the burning heat power and burning speed required by the squib 1. Further, the filament 2
In order to secure a moderately flexible rigidity required for the squib 1 for continuously igniting a plurality of candle burning wicks, a nitrifying cotton plasticizer or a nitrifying cotton softener is used. A predetermined amount may be added to the cotton solution. Here, as a plasticizer for nitrified cotton or a softener for nitrified cotton,
Phthalate plasticizers such as camphor, dibutyl phthalate and dioctyl phthalate, fatty acid plasticizers such as dioctyl adipate and dioctyl sebacate, and epoxy plasticizers such as epoxidized soybean oil can be used. Some agents or softeners emit black smoke when burned depending on the amount of the additive, so it is necessary to pay attention to the type and amount of the plasticizer or softener used. For these reasons, fatty acid-based plasticizers such as dioctyl adipate and dioctyl sebacate are preferable for the addition to the nitrified cotton solution, and the amount added is preferably 30 parts by weight per 100 parts by weight of the nitrified cotton of the nitrified cotton solution.
It is suitable that the amount is not more than 10 parts by weight, preferably not more than 10 parts by weight.

As the metal wire 3 used for the squib 1 of the present invention, a commercially available metal wire can be used. The effect of candle ignition, the configuration of the metal squib 3 in the squib 1, The squib 1 for use purpose and direction
In consideration of the melting point, tensile strength, and the like required for the above, the material of the metal wire 3 to be used, the diameter of the wire, the number of wires to be used, and the like may be appropriately selected and determined. The metal wire 3 may be formed by bundling or twisting a plurality of thin metal wires. The metal wire 3 used for the composite filament 6 composed of the filament 2 and the metal wire 3
In the case of a small diameter, there is a good fit with the thread-like body 2, and it may be inconspicuous even when it is stretched, which may be convenient for production.
As an example of the composite thread 6, there is a thread using a tungsten wire having a diameter of 0.07 mm. In general, when the metal wire 3 having a relatively small diameter is used, the metal wire 3 remaining after the combustion of the squib 1 is inconspicuous, hardly visible, and does not hinder the performance. In addition, if the metal wire 3 having a relatively large diameter is used, it is possible to express a design, a pattern, a character, and the like by itself. The width can be expanded. If tungsten, nichrome, or the like is used as the material of the metal wire 3, for example, even if it has a very thin shape, it is unlikely that the wire will melt and break even by the heat of the firing wire 1,
It is convenient when used as a thin line. On the other hand, when copper or aluminum is made into a thin wire, it may be melted by heat generated when the squib 1 is burned. However, if it is adopted for the metal wire 3 having a relatively large diameter, it is easy to process without melting and is convenient.

The filament 2 containing nitrified cotton and the metal wire 3
When impregnating or applying the nitrified cotton 4 solution obtained by dissolving the nitrified cotton 4 in an organic solvent or the like, the metal wire 3 is integrated with the filament 2 before drying and then dried after drying. In this way, the fusible wire 1 may be formed inseparably and the fusible wire 1 may be used.
May be melted to provide an adhesive property, and the metal wire 3 may be bonded to form the squib 1. In addition, nitrification cotton 4
The filament 2 and the metal wire 3 are wound around one another, entangled, twisted, hooked, partially adhered with a nitrifying cotton 4 solution, the filament 2 and the material of the filament 2 etc. The squib 1 may be constituted by a means such as partially tying and joining. Furthermore, the filament 2 and the metal wire 3 are aligned or twisted into a bundle to form a composite filament 6, and the composite filament 6 is impregnated or coated with a nitrified cotton 4 solution. The nitriding cotton 4 may be included by a means to form the squib 1.

In the squib 1 of the present invention, as the pyrotechnic iron powder 5 used together with the nitrified cotton 4, iron powder generally used for fireworks can be used. The particle size is 4
Those having a particle size of about 00 μm or less are preferable, and those having a small particle size are more preferable because the residue during combustion is small and fine sparks can be gorgeously dispersed in the effect. 8 among them
The pyrotechnic iron powder 5 having a particle size of about 8 μm or less has a good spark balance and is more preferable. The pyrotechnic iron powder 5 may have a configuration particularly included in the nitrified cotton 4 in the surface layer of the squib 1.
The filament 2 is sufficiently burned by the burning of the nitrified cotton 4, and the pyrotechnic iron powder 5 present in the surface layer becomes a spark and easily jumps out of the squib 1 so that the appeal in the performance is improved. Further, it is preferable because the combustion residue can be reduced. Such a nitrified cotton 4 on the surface of the squib 1
As an example of a method of manufacturing the squib 1 including the pyrotechnic iron powder 5 therein, the filament 2 and the metal wire 3 are aligned and bundled or twisted to form a composite filament 6. Then, the nitrified cotton 4 solution is impregnated or coated on the composite filamentous body 6 by means of impregnating or applying the nitrified cotton 4 solution, and after primary drying, the nitrified cotton 4 solution in which the pyrotechnic iron powder 5 is dispersed is used. The nitriding cotton 4 may be included by impregnating or applying the coating, and then dried secondarily to form the squib 1.

Further, a coloring agent 7 may be used together with the nitrified cotton 4 for the purpose of coloring the combustion flame of the squib 1 of the present invention with a desired color. As the coloring agent 7, a coloring agent for coloring a combustion flame can be generally used. Strontium compounds such as strontium carbonate and strontium nitrate as red agents, lithium compounds such as lithium carbonate as red agents, sodium compounds such as sodium oxalate as yellow agents, barium compounds such as barium nitrate and barium carbonate as green agents, As the blue agent, compounds such as copper sulfate, flower patina, copper oxide and the like are used. An oxidizing agent can be used together with the coloring agent 7 as needed to further improve the coloring property. As the oxidizing agent used, those usually used as oxidizing agents can be used. Among them, chlorates such as potassium chlorate, perchlorates such as ammonium perchlorate and potassium perchlorate, nitric acid Nitrate salts such as sodium and potassium nitrate are preferably used. Here, when the coloring agent 7 or the oxidizing agent is used, some types of the metal wire 3 may cause a chemical reaction such as oxidation, so care must be taken. In this case, a chemical reaction such as oxidation can be avoided by applying means such as coating and coating to the metal wire 3 in advance.
When the pyrotechnic iron powder 5 is used for the squib 1 together with the nitrified cotton 4, the oxidizing agent may oxidize the pyrotechnic iron powder 5 and may not be able to expect the effect of jumping out as a spark. Care must be taken not to oxidize the fireworks iron powder 5.

If the contents of the iron powder 5 for fireworks and the coloring agent 7 of the squib 1 of the present invention are too small, combustion residues are small, but effective spark generation and coloring cannot be expected. Although the generation of sparks and coloring can be expected, not only the amount of combustion residues increases but also the burning speed becomes slow, which is not preferable for the squib 1. On the other hand, when the degree of nitrification of the nitrified cotton contained in the filament 2 containing the nitrified cotton 4 is low or the content is small, the thermal power at the time of burning the filament 1 is weak, so that the content of the iron powder 5 for fireworks and the like is low. Even if the amount is small, the protrusion of the iron powder for fireworks 5 and the like is small and the combustion residue increases, and the combustion speed is also low. On the contrary, when the nitrification degree of the nitrified cotton contained in the filament 2 containing the nitrified cotton 4 is high or the content thereof is large, the heating power at the time of burning the squib 1 is so strong that the iron powder 5 for fireworks and the like are contained. Even if the amount is large, the amount of the fireworks iron powder 5 and the like jumps out and the combustion residue is small, and the burning speed of the squib 1 does not decrease. From these facts, the content of the pyrotechnic iron powder 5 and the coloring agent 7 in the squib 1 according to the present invention depends on the degree of nitrification of the nitrocellulose 4 contained in the filament 2 and the degree of the content. It can be determined appropriately so that the generation of sparks and coloring can be expected, the burning residue is small, and the burning speed of the squib 1 when the plurality of candle wicks are continuously ignited is not slowed down.

Next, an example of a method for manufacturing the squib 1 according to the present invention will be described below. The composite thread 6 is obtained by aligning or twisting the thread 2 and the metal wire 3 in which a plurality of strands of the cellulosic natural fiber such as cotton and hemp are formed into a bundle or twist. After dissolving a predetermined amount of industrial nitrocellulose in a nitrifying cotton solvent such as ethyl acetate and impregnating or applying a nitrifying cotton 4 solution whose viscosity has been adjusted with a cosolvent, diluent, or the like, to the composite filament 6 First, it is dried by hot air, then impregnated or coated with a nitrified cotton 4 solution in which a predetermined amount of pyrotechnic iron powder 5 is dispersed, and then dried by hot air to produce the squib 1. The conditions such as the drying temperature, drying time, and air volume during the primary drying and the secondary drying are as follows: the concentration of the nitrified cotton 4 solution, the amount of the nitrified cotton 4 solution contained in the filament 2, and the amount of the nitrified cotton to the filament 2. The amount may be appropriately determined in consideration of the application amount of the four solutions. As the drying means, in addition to the drying by the hot air, wind drying, drying by a heat source such as infrared rays, natural drying, vacuum drying, drying under reduced pressure, the production amount,
The most suitable one may be selected in consideration of the manufacturing location and the conditions such as whether the state of the squib 1 to be manufactured is good.

An example of the content of the pyrotechnic iron powder 5 of the squib 1 of the present invention will be described below. The composite filament 6 composed of the filament 2 and the metal wire 3 contains about 0.4 g / m of nitrified cotton having a nitrification degree of about 12.0% as nitrogen and contained in the nitrified cotton 4 in the surface layer. 0.02 g / m of content of iron powder 5 for fireworks,
The squib 1 of about 0.06 g / m and about 0.15 g / m
Were used to continuously ignite multiple candle burning wicks. At this time, in the squib 1 in which the content of the pyrotechnic iron powder 5 was about 0.02 g / m, continuous ignition of the plurality of candle wicks was smoothly performed, and the combustion residue during the combustion was almost completely eliminated. There was no residue, but there were few sparks. Next, the content of the iron powder 5 for fireworks was reduced to 0.0
In the squib 1 at about 6 g / m, continuous ignition of the plurality of candle burning wicks was smoothly performed, and fine sparks were scattered gorgeously, but the burning residue during the burning was slightly reduced. It was almost rest. Further, in the squib 1 in which the content of the pyrotechnic iron powder 5 is about 0.15 g / m, continuous ignition of a plurality of candle wicks is performed smoothly, and more fine sparks are gorgeously produced. The fluttering was visibly observed, but the burning residue at the time of burning was slightly increased, and the burning speed was slightly slowed down.

If the squib 1 of the present invention is used, for example,
As shown in FIG. 4, it is possible to continuously ignite even a candle burning core several tens of cm and several meters away. Further, if the metal wire 3 having a relatively large diameter is used as the metal wire 3 constituting the squib 1, it is possible to express designs, patterns, characters, etc. by itself, and to support and fix the squib 1. Is no longer necessary, and the range of usage and effects can be expanded. For example, if a design such as a spiral is created by the squib 1 as shown in FIG. 6, even when only the design is ignited, fine sparks can be brilliantly enjoyed, and the effect can be appreciated. It becomes a production method. If necessary, a plurality of the squib wires 1 may be used by bundling or twisting, or the squib wire 1 may be used in a mesh form. Further, if the design is as shown in FIG. 6, it can be stored compactly at the time of packaging, and can be an excellent presentation that can be easily assembled and set at the time of use. For example, as shown in FIG. 7, the squib 1 according to the present invention can be integrated with the burning core of the candle, and with the small amount of the burning residue, the fine sparks are scattered gorgeously and burned. It can be said that igniting the burning wick is an effective production method.

The metal wire 3 used in the squib 1 of the present invention is easily corroded, such as copper or aluminum, depending on its material. Therefore, corrosion may be further promoted, and long-term quality stability may not be achieved. Therefore, the metal wire 3 to be used is preferably a metal or an alloy which is hardly corroded, or even a metal wire which is easily corroded is plated with a purpose of preventing corrosion, or is coated with a natural resin or a synthetic resin. Can be used.

A squib 1 used for igniting a candle according to the present invention comprises a filament 2 containing nitrified cotton 4 and a metal wire 3. A conventional “fire wire having a configuration including nitrified cotton” can be used for the “filament 2 including nitrified cotton 4” of the present invention. As the igniter 1 of the present invention, which is composed of the conventional “igniter containing nitrified cotton” and the metal wire 3,
The squib 1 of the present invention which is composed of "a squib comprising nitrified cotton and further comprising a coloring agent" and a metal wire 3; "a squib comprising a nitrifying cotton and further comprising a coloring agent and an oxidizing agent"; and a metal wire. 3, the igniting wire 1 of the present invention composed of “a igniting wire including nitrified cotton mixed with metal powder” and the metal wire 3, and The squib 1 of the present invention, which comprises a squib having a structure in which metal powder is adhered to the surface thereof and a metal wire 3, the squib having a structure containing nitrified cotton mixed with a metal powder and a coloring agent, and the metal wire 3 The squib 1 of the present invention, comprising: a squib 1 comprising nitrified cotton and further having metal powder and a coloring agent adhered to the surface thereof;

[0020]

Next, a squib and a continuous ignition candle used for igniting a candle according to the present invention will be described more specifically with reference to examples and comparative examples. Example 1: A filamentous body obtained by bundling three cotton yarns of 40 counts and one 0.07 mm tungsten wire was impregnated with a nitrified cotton solution obtained by dissolving and mixing 8 parts of industrial nitrocellulose in 20 parts of ethyl acetate. It was dried with hot air to obtain a fuse. This was used as a sample of Example 1. Example 1
As shown in FIG. 4, the steel hooks at both ends 3 m away from each other were stretched and fixed without slack so that the elevation angle was 20 degrees. Further, as shown in FIG. 4, five candles (diameter 6 mm, length 80 mm) are placed at a distance of 10 cm from a position 50 cm away from the lower fixed portion, and at a distance of 20 cm from a position 2 m further away from the lower fixed portion. Four candles (diameter 6 mm, length 80 mm) were arranged. In a state where the illumination was turned off and darkened, ignition was performed from the lower end of the squib filament stretched over a distance of 3 m. Since the metal wire used was a thin wire, the candles that were almost invisible and floating in the air slid upward, igniting the passing candles one after another, and all the candles were lit.

Example 2: A filamentous body obtained by bundling four cotton yarns of count 40 and a stainless steel wire having a diameter of 0.1 mm was impregnated with a nitrified cotton solution obtained by dissolving and mixing 8 parts of industrial nitrocellulose in 20 parts of ethyl acetate. After that, it was dried with hot air to obtain a fuse. This was used as a sample of Example 2. Example 2 After fixing one end of the 750 cm sample to a steel hook at a location where a circular ring made of steel with a radius of 75 cm and a 45-degree inclined stand divides the ring circumference into five equal parts as shown in FIG. , One on the other hook while keeping the tension
It was rolled and fixed, and stretched and fixed to a total of five hooks while sequentially providing tension. Further, at each of the five intersections of the squib, one burning wick of a total of five candles (diameter 10 mm, length 200 mm) was arranged upright so as to contact the squib. Then, in the dark, with the lights turned off, the star-shaped lower right apex was ignited toward the front. The ignited flame split into two parts, igniting the candle at the intersection of the ignition filaments, and the flames ignited one after another along the star-shaped flame path.

In the conventional candle continuous ignition method, a squib is required to be held in advance by bonding or the like to the burning core of the candle, and not only is the work complicated, but also the setting of the candle stand during the production is troublesome and troublesome. However, the squib of the present invention can be set very simply by fixing the squib while stretching it over a predetermined fixture, and arranging the candle in a form in which a candle burning wick is brought into contact with the squib. In addition, by fixing the squib to a desired position on the squib wire fixing device of the candle stand, it is possible not only to easily create a flame path of a desired design, but also to use a thin metal wire that is difficult to visually recognize. The effect that the flame floating in the air is split into two hands or the candle is lit while coalescing is created.

Example 3 and Comparative Example 1: Iron powder 2 for fireworks
To 28 parts of a nitrified cotton solution obtained by dissolving and mixing 8 parts of industrial nitrocellulose in 20 parts of ethyl acetate, and sufficiently stirred to obtain a drug solution. Next, the chemical liquid was impregnated into a filament formed by bundling three cotton yarns of count 40, followed by drying with hot air to obtain a fuse. This was designated as Comparative Example 1 sample. Also, ethyl acetate 20
A nitrification cotton solution in which 8 parts of industrial nitrocellulose is dissolved and mixed is impregnated into a composite thread formed by bundling three cotton counts 40 and one nichrome wire having a diameter of 0.07 mm, and then primary drying with hot air After that, 2 parts of iron powder for fireworks were stirred and dispersed in 28 parts of a nitrified cotton solution obtained by dissolving and mixing 8 parts of industrial nitrocellulose in 20 parts of ethyl acetate, and the mixture was secondarily dried to obtain a fuse. This was used as a sample of Example 3.
As shown in FIG. 1, each of the sample of Example 3 and the sample of Comparative Example 1 was made up of 10 candles (diameter 6 m).
m, length of 80 mm) with a nitrocellulose adhesive so that the interval between the candles is 80 mm, and then arranged in a straight line with a 45 degree elevation angle and ignited from below. Then, the combustion state of the squib, the effect of generating a spark, the degree of continuous ignition of the candle, and the like were observed.

As shown in FIG. 3, the sample of Comparative Example 1 burned while scattering fine sparks, but the combustion residue of the squib remained in a tail-like manner and was remarkably tended to adhere to the upper side surface of the candle. Adhesion of the residue to the candle is observed from the second, third, sixth and eighth from the bottom,
The tail-like combustion residue adhering to the upper side of the third and eighth candles was ignited and became a new combustion wick. These candles were observed to burn out more rapidly and burn out faster than other candles. On the other hand, the sample of Example 3 emits fine sparks more brilliantly as shown in FIG. 2, and the combustion residue of the squib burns out in a state of being attached to the nichrome wire. There is no inconvenience that the burning residue of the Nichrome wire adheres to the upper surface of the candle. Furthermore, some of the unburned Nichrome wire touched the top of the candle or touched the foot of the candle, but the metal wire was 0.07 mm. Because of the thinness, there was no burning inconvenience such as dissolving the wax of the candle and increasing the dripping of the wax. And
The ten candles burned evenly and all candles burned out about 20 minutes after ignition. Furthermore, since the used nichrome wire is as thin as 0.07 mm, it is hardly noticeable visually, so that there is no trouble in the production.

EXAMPLE 4 A nitrified cotton solution obtained by dissolving and mixing 8 parts of industrial nitrocellulose in 20 parts of ethyl acetate was impregnated into a filament bundle of three 40-count cotton yarns, and then primary dried by hot air drying. After that, 1.5 parts of iron powder for fireworks was stirred and dispersed in 28 parts of a nitrified cotton solution obtained by dissolving and mixing 8 parts of industrial nitrocellulose in 20 parts of ethyl acetate, and the mixture was secondarily dried to obtain a fuse. Example 2 was obtained by winding the two squib wires around 2 m of a chrome-plated steel wire having a diameter of 0.9 mm. As shown in FIG. 6, the sample of Example 4 formed into a helical shape was suspended, and the lower end of the sample was ignited in the dark with the illumination turned off. In the sample of Example 4, it was observed that the flame gradually grew into a helical shape, and fine sparks fluttered up while scattering gorgeously.

In the igniter, the method for manufacturing the igniter, and the method for igniting the candle according to the present invention, the igniter is composed of the filament including nitrified cotton and the metal wire by the above-described structure. Burning of the squib proceeds along the metal wire. For this reason, even when the interval between the burning cores of the candles to be ignited is wide, the squib does not jump up or down, making it possible to burn smoothly and reliably ignite the candle, and to obtain a tail-like combustion residue. There is no worry about the flame going out. Further, since the metal wire is used as a component, the tensile strength is relatively high, so that not only the candle burning cores can be connected to each other but also can be stretched while being fixed to fixing means such as a hook. Using this technique, it is possible to install the device over a considerably long distance, and various designs can be easily represented by the flame of the squib. Further, if a thin wire made of a heat-resistant material is used for the metal wire, the metal wire remaining after the combustion of the squib is almost invisible, and the flame floating in the air moves to ignite the candle. To be observed. On the other hand, by using the metal wire having a relatively large diameter, it is possible to form a desired design, characters, etc., and to ignite the candle while expressing the desired design, characters, etc. with the flame of the squib. Further, in the squib containing the pyrotechnic iron powder, the squib is quickly burned by the burning of the nitrified cotton, and the pyrotechnic iron powder becomes fine sparks and gorgeously dances. Further, the combustion residue burns out while snuggling to the metal wire, the combustion residue does not hang down in a tail shape, and the tail-shaped combustion residue hangs down in such a manner as to cling to the candle body, and this portion becomes a new combustion core. There is no such thing as burning up. Furthermore, during the ignition for the continuous ignition of the candle, not only the flame does not extinguish but also the continuous ignition of the candle burning wick can be ensured, but also the tail-like combustion It is an excellent one that can produce a gorgeous effect with a high visual appeal, which has little residue and can also enjoy a flame of remarkable color. Further, by using a squib and a method for producing a squib used for candle ignition and a method for igniting a candle according to the present invention,
It is possible to achieve an unprecedented superior effect in the production and decoration by the combustion flame.
