Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a candle-like illuminating body having a high safety against fire and excellent in decorativeness, and a liquid combustion agent for the illuminating body.

[0002]

2. Description of the Related Art Conventionally, candles and oil lamps have been widely used for creating and producing an atmosphere for ceremonial occasions, restaurants, parties and the like. Various proposals have been made to prevent the occurrence of fire due to these illuminating bodies. For example, in a candle, a candlestick having a function of extinguishing a flame by discharging a fire extinguishing member such as water and sand contained in the candlestick when it falls (see Japanese Utility Model Publication No. 63-10793), and a candle holding holder when falling. A candlestick (see Japanese Patent Publication No. 1-33822) for extinguishing a candle by automatically storing a candle therein by a spring has been proposed. On the other hand, in the oil lamp, since a liquid combustion agent having a low flash point is used, a means for isolating the flame and the combustion agent portion so as not to be close to each other is provided to prevent ignition of the combustion agent. Furthermore, an oil lamp has been proposed in which a liquid combustion agent having a high flash point such as vegetable oil is illuminated by a floating combustion wick (Japanese Utility Model Publication No. 1-166910, Japanese Utility Model Publication No. 63-).
164107).

[0003]

[Problems to be Solved by the Invention]
In the candlestick proposed in 10793, when water is used as a fire extinguishing member, the water evaporates during use and the amount of water decreases, and the amount necessary for extinguishing the flame may not be secured.
Although the capacity of sand or a mixture of water and sand does not decrease much, the fluidity is low and the reliability of fire extinguishing is poor. The candlestick proposed in Japanese Examined Patent Publication No. 1-38322 extinguishes itself if the candle can be reliably stored in the holder when it falls, but the candle used is of a size that can be stored in the holder. Limited to In addition, since the mechanical structure is complicated, the storage is not reliable. In addition, none of the above candlesticks has consideration for decorativeness. On the other hand, the oil lamp has a gap and an air escape hole between the combustion core holder and the combustion agent container that separate the flame and the combustion agent so that they do not come close to each other. There is a risk that the combustion agent leaks from the escape hole, and a combustion flame ignites the leaked combustion agent to cause a fire.

Further, the oil lamp which is proposed in Japanese Utility Model Publication No. 1-166910 and Japanese Utility Model Publication No. 63-164107 and which uses a floating combustion core to light a liquid combustion agent having a high flash point, such as vegetable oil, is used as the combustion agent when it falls. Although it does not ignite and there is little risk of fire, the combustion wick clogs the combustion wick, and the flame becomes smaller over time, and it is not possible to obtain a sufficient flame effect.

Therefore, an object of the present invention is to provide a candle-like illuminating body which is highly safe against fire and has excellent decorativeness. Another object of the present invention is to provide a liquid combustion agent for the above candle-like illuminating body.

[0006]

That is, a first aspect of the present invention is directed to a combustion wick flame in which a liquid container having an opening in an upper portion and a liquid surface contained in the liquid container are lower than the opening. Is a candle-like illuminating body composed of a liquid combustion agent that does not ignite and a combustion wick that is erected upright on the bottom of the containing portion of the liquid containing body. The second invention is a liquid combustion agent for the above candle-like illuminating body.

[0007]

With the above structure, the candle-like illuminating body of the present invention, which has a combustibility similar to a candle and a production effect by a flame, is
The flame does not ignite the combustion agent even when it falls over, not only when it is used, but also it is possible to quickly extinguish the combustion wick flame, which is highly safe against fire. Furthermore, by selecting the liquid container according to the use atmosphere, it is possible to provide a candle-like illuminating body excellent in decorativeness, which is not available in the past.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a candle-like illuminating body of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of a candle-like illuminating body of the present invention, in which a liquid combustion agent 1 is contained in a containing portion B of a liquid containing body 2 having an opening A in the upper portion, and moreover, liquid containing A combustion wick 3 having a lower end supported by a support tool 4 and a tip protruding from the liquid surface L of the liquid combustion agent is erected in an upright state on the bottom of the housing portion of the body. Above the liquid surface of the liquid combustion agent, the liquid container 2 has an opening that does not impair the combustibility, such as incomplete combustion caused by interruption of air supply to the flame of the combustion wick 3. It is necessary to provide. Usually, a container having a wide opening at the upper end as shown in FIG. 1, for example, wine glass, cocktail glass, brandy glass, tumbler glass, etc. is preferably used.

The liquid container 2 may be shaped so as to cover the upper flame portion of the combustion wick 3 as shown in FIG. In this case, one or a plurality of openings 5 for supplying air to the flame of the combustion wick 3 must be provided above the combustion agent liquid level L so as not to impair the combustibility of the combustion wick. Further, it may have a structure in which a container having an upper end opening is covered, that is, a shape capable of being separated at the upper part of the liquid surface of the combustion agent.
The opening may have an arbitrary shape and may have a size that does not impair the combustibility of the combustion wick flame. In the case of the shape as shown in FIG. 2, the upper portion of the flame is heated by the combustion wick flame, so that a material having heat resistance, for example, glass, porcelain, heat resistant resin or the like is preferably used.

The material of the liquid container is usually glass, ceramics, resin, metal, stone or the like having heat resistance. In particular, in order to enjoy the atmosphere caused by the flame during burning, a transparent or translucent one is preferable. Further, transparent colored glass and milky white thin porcelain are suitable for creating an atmosphere due to flames such as flickering and irregular reflection of flames through glass and porcelain.

As the combustion wick 3 which is erected in an upright state in the containing portion of the liquid container 2, a combustion wick usually used for a candle is applied. That is, natural plant fibers such as cotton fibers and cellulosic fibers such as regenerated cellulosic fibers, which are mainly composed of these cellulosic fibers, for example, flammable fibers such as polyolefin fibers and polyvinyl alcohol fibers or zinc, lead, solder, etc. The combustion core obtained by weaving or knitting the mixed fiber in which the low melting point metal fiber of 1. is woven or knitted is cut into a predetermined length to be used as a combustion core. It is also possible to use a combustion wick in which a thin metal wire is bundled with fibers, or the thin fiber wire is wound around the thin metal wire to make the fiber bundle self-supporting.

The lower end of the combustion wick 3 is fixed to the bottom of the containing portion of the liquid containing body 2, and stands upright from the bottom of the containing portion of the containing body. Normally, it is erected vertically from the bottom of the containing portion of the containing body, but it may be inclined or curved to the extent that combustion is not hindered.

The lower end of the combustion wick is clamped and fixed by a plurality of claws 7 provided on a support 4 made of a heat-resistant plate such as metal as shown in FIGS. 3 (a) and 3 (b). As a method for fixing the combustion wick to the heat-resistant plate, known means such as adhesion or adhesive fixing means can be used in addition to the method shown in FIG. Alternatively, as shown in FIGS. 4 (a) and 4 (b), the lower end of the combustion wick 3 may be housed in a cylinder 8 having a short heat resistance, and the cylinder may be crushed to clamp the wick or to fix the wick. The combustion wick 3 whose lower end is supported by the support tool 4 is erected in an upright state on the bottom of the storage portion of the liquid storage body 2 via the support tool 4. Further, as shown in FIG. 5 (a), the support 4 is provided with a core reinforcing portion 9 made of a thin metal wire, and the combustion core 3 is wound around the core reinforcing portion, or in a tubular shape as shown in FIG. 5 (b). When a wound wick is used, the wick reinforcing portion 9 made of the thin metal wire may be penetrated into the center of the cylindrical combustion wick 3 to erect the combustion wick. Further, as shown in FIG. 6, a recessed holding portion 10 matching the size of the combustion wick 3 may be provided at the bottom of the containing portion of the liquid container to set the combustion wick upright. In the liquid container provided with the support portion, there is no residue such as the core support tool, and the maintenance after use is extremely easy.

Further, as shown in FIG. 7, when a magnetic substance 11 such as iron or resin is adhered or adhered to the bottom of the accommodating portion of the liquid accommodating body 2, the combustion wick 3 is intervened via the metallic support tool 4. Can be detachably attached to the bottom of the liquid containing portion by magnetic attachment.
On the other hand, when using a magnetized support made of metal, metal or the like may be fixed to the bottom of the liquid containing portion. When the liquid container 2 falls down, as shown in FIG.
Stays in the storage portion of the liquid container 2 and can be completely separated from the liquid combustion agent 1 leaking from the liquid container,
It is possible to quickly extinguish the flame 12 of the combustion wick.

It is important that the flame of the combustion wick does not ignite the liquid combustion agent 1 accommodated in the accommodating portion of the liquid container, and since the candle-like lighting body is mainly used indoors, the candle. It is desirable to use an odorless soot that does not generate soot during combustion. The lower limit of the flash point depends on the shape of the liquid container, for example, the size of the upper opening and the depth of the liquid container, but the depth of the liquid container such as wine glass is relatively deep. In general, those having a temperature of 150 ° C. or higher are preferably used. On the other hand, when the container of the liquid container is a shallow dish-shaped container, a liquid combustion agent having a flash point of about 120 ° C. can be used.

Examples of such liquid combustion agents include butyl oleate, aliphatic monobasic acid esters such as glycerin monooleate, dibutyl adipate, n-hexyl adipate, diisononyl adipate, di-2-ethylhexyl adipate, Dialkyl adipate 61
0, diisodecyl adipate, dibutyl diglycol adipate, di-2-ethylhexyl azelate, dibutyl sebacate, di-2-ethylhexyl sebacate, etc., aliphatic dibasic acid esters, triethylene glycol di-2-ethylbutyrate, acetylricinol Oxyacid esters such as methyl acidate, butyl acetylricinoleate, tributyl acetylcitrate, soybean oil, cottonseed oil, rapeseed oil, castor oil, olive oil, safflower oil, whale oil, saturated higher fatty acids such as isostearic acid, isostearyl alcohol Saturated higher alcohols such as n-
Paraffin, liquid paraffin, saturated hydrocarbon such as hydrogenated polybutene, and the like can be mentioned, and they can be used alone or in combination of two or more kinds. The flash point can be adjusted arbitrarily by mixing multiple types. As the liquid combustion agent, one having a flash point at which the flame does not ignite can be selected depending on the shape of the liquid container. Among them, diisononyl adipate, di-2-ethylhexyl adipate, and dialkyl adipate 610 are inexpensive, have a high flash point of 180 ° C. or higher, are colorless and odorless, and generate less soot during combustion, and are preferably used because of good combustibility. It is preferable to add a coloring agent to the liquid combustion agent so that the color of the combustion agent can be enjoyed. Moreover, you may contain an aromatic agent and a deodorant.

Further, as shown in FIG. 9, water 13 is put in the containing portion of the liquid containing body 2, and then a predetermined amount of the liquid combustion agent 1 which is not mixed with water is added to laminate the water-liquid combustion agent. You can also let it. By adding water, when the flame of the combustion wick 3 drops to the water surface during combustion, the fire can be extinguished automatically. By adjusting the layering ratio of water and the liquid combustion agent, the combustion time can be set arbitrarily, and the safety against fire in the event of a fall can be enhanced.

Experimental Example 1 As a liquid container, two commercially available wine glasses having an opening diameter of 40 mm, a depth of 55 mm and a volume of 48 ml were used, and a cotton core for a candle was used as a combustion core. The circular combustion core support shown in FIG. 3 (a). After being held by, the wine glass was placed at the bottom of the liquid storage portion. Diisononyl adipate (flash point 220 ° C) 30 as a liquid combustion agent in the container of the wine glass
When ml was poured in and the cotton core was ignited, good burning properties were exhibited without the generation of soot. Further, about 3 hours after the liquid combustion agent was halved, one wine glass was turned over on a table cloth made of pure cotton. The combustion agent in the storage portion of the wine glass spilled out of the glass at once as shown in FIG. 8 (b), but the combustion flame portion remained in the wine glass and self-extinguishing was confirmed after about 10 seconds. In addition, the other illuminating body is such that the combustion wick flame does not ignite the combustion agent in the combustion process,
After 6 hours and 23 minutes, self-extinguishing occurred due to exhaustion of the combustion agent.

Experimental Examples 2 and 3 and Comparative Examples 1 and 2 Twelve commercially available wine glasses each having an opening diameter of 40 mm, a depth of 55 mm and a volume of 48 ml were used as liquid containers, and each of them was divided into 4 groups, each of which was n-paraffin. Dioctyl adipate, a mixed liquid of 3 volumes of n-paraffin and 7 volumes of dioctyl adipate, 30 ml of a mixed solution of 6 volumes of n-paraffin and 4 volumes of dioctyl adipate were poured, and the combustion core was held by a steel circular combustion core support. After being placed at the bottom of the liquid containing portion of the wine glass, it was ignited, and it was observed whether or not the combustion core flame ignited the combustion agent during the combustion process. Table 1 shows the results.

[0021]

[Table 1]

Experimental Example 4 Six commercially available wine glasses each having an opening diameter of 40 mm, a depth of 55 mm and a capacity of 48 ml were used as the liquid container, and two wine glasses each were used.
Divide into groups, and water and D610A (dialkyl adipate 610, flash point 222 ° C) 20 ml and 10 m, respectively.
1, 15 ml and 15 ml, 10 ml and 20 ml were poured, and after confirming the separation into two layers of water and D610A, FIG.
When the combustion wick held by the support shown in (b) was placed at the bottom of the liquid containing portion of the wine glass and then ignited, good combustion properties were exhibited. Further, after one hour, one of each group was laid down on a table cloth made of pure cotton, and in both cases, the combustion agent and water flowed out at once, but the combustion flame portion remained in the storage portion, and from 8 seconds. It extinguished itself in 12 seconds. Also,
The combustion time until the self-extinguishing due to the exhaustion of the combustion agent of the remaining lighting bodies of each group was 112 minutes, 187 minutes, and 229 minutes, and timed self-extinguishing was confirmed. Therefore, by laminating a predetermined amount of the combustion agent on water, the combustion time can be arbitrarily set, and reliable timed self-extinguishing can be performed, and the safety against fire in the event of a fall can be further enhanced. Further, the decorative effect can be enhanced by coloring both or either of the combustion agent and water.

Experimental Example 5 Two commercially available cocktail glasses having an opening diameter of 60 mm, a depth of 58 mm and a volume of 54 ml were used as a liquid container, and a magnetic material was adhered and fixed to the bottom of the container, and the steel shown in FIG. 3 (b) was used. After magnetically sticking the combustion core held by the rectangular core support to the bottom of the accommodating part, 30 ml of dioctyl sebacate (flash point 215 ° C.) as a liquid combustion agent was poured and ignited, soot was not generated, which was excellent. It showed flammability. Furthermore, after about 3 hours when the combustion agent was halved, one of the lighting bodies was turned over on a table cloth made of pure cotton, and as shown in FIG. However, the combustion flame portion was surely magnetized to the bottom portion of the containing portion, and self-extinguishing was confirmed after 10 seconds. Therefore, when the combustion wick support is magnetically attached to the bottom of the combustion agent storage unit, the combustion flame section and the combustion agent can be completely separated and the combustion wick flame can be quickly self-extinguished in the event of a fall. It will further enhance the safety of The other illuminating body extinguished itself after 7 hours and 16 minutes due to exhaustion of the combustion agent.

Experimental Examples 6 and 7 and Comparative Examples 3 to 5 The lower limit of the flash point required for the liquid combustion agent for the candle-like illuminating body of the present invention is the opening diameter and the depth of the liquid containing body used. , It depends on the shape such as capacity. Therefore, n-paraffin (flash point: 120 ° C.) as a liquid combustion agent was put into each of three containers of five types having the following shapes, and the presence or absence of ignition of the combustion core flame to the combustion agent during the combustion process was examined. The results are shown in Table 2.

The candle-like illuminating body of the present invention, which has the combustibility similar to the candle and the effect of the flame by the above-mentioned constitution, does not catch the flame on the combustible agent even when it is overturned during use. In addition, it is possible to quickly extinguish the combustion core flame, which is highly safe against fire. Furthermore, by selecting the liquid container according to the use atmosphere, it is possible to provide a candle-like illuminating body excellent in decorativeness, which is not available in the past.
