Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a candle which is excellent in decorativeness and has high safety against fire, and a gel-like burning agent for the candle.

[0002]

2. Description of the Related Art Conventionally, candles have been widely used for creating and producing an atmosphere for ceremonial occasions, restaurants, parties and the like. Then, various proposals have been made to produce a candle having transparency as a candle having further excellent decorativeness. For example, a transparent candle composition obtained by gelling a flammable solvent with a thermoplastic polyamide resin (Japanese Patent Publication No.
No. 4640), an aliphatic polyamide resin, an aliphatic polyester polyamide resin, and a transparent candle composition gelled with a gelling agent selected from a mixture thereof (see Japanese Patent Publication No. 59-30896). Also,
A transparent candle prepared by gelling a vegetable oil with benzylidene sorbitol has also been proposed (Japanese Patent Publication No. 58-21797).
(See the official gazette).

[0003]

However, Japanese Patent Publication No. 2-4
The transparent candle compositions proposed in Japanese Patent Publication No. 640 and Japanese Patent Publication No. 59-30896 all contain polyamide resin and thus generate an amide odor during combustion, and because nitrogen oxide is contained in the combustion gas, the surrounding atmosphere is affected. There was a problem that it worsens. Further, the transparent candle proposed in Japanese Patent Publication No. 58-17597 has a problem that soot is easily generated because it contains a gelling agent having a benzene ring, and a strange odor is emitted when extinguishing a fire. Therefore, none of the above proposed candles is suitable as a candle used to create an atmosphere in the interior, especially in the surroundings.

Therefore, an object of the present invention is to solve the above-mentioned problems, to prevent generation of a bad odor during combustion, to reduce the generation of soot, to be excellent in decorativeness, and to be highly safe against fire, especially indoors. To provide candles suitable for use. Another object of the present invention is to provide a gel-like burning agent for the above candle.

[0005]

[Means for Solving the Problems] That is, the first aspect of the present invention gels a combustion agent container having an opening at the top and a liquid combustion agent having a flash point at which the combustion wick flame does not ignite with 12-hydroxystearic acid. And a gel-like combustion agent accommodated in the combustion agent container such that the upper surface of the combustion agent is lower than the opening, and a combustion wick standing upright on the bottom of the accommodation section of the combustion agent container. It is a candle. The second invention is a gel-like burning agent for the above candle.

[0006]

The candle according to the present invention does not generate a bad odor and hardly emits soot upon burning, like a conventional candle, even though it uses a gel-like burning agent. In addition, even when the candle falls over, the flame does not ignite the combustion agent during use, and the safety against fire is high. Furthermore, by selecting a combustion agent container having a shape or material suitable for the use atmosphere, it is possible to provide a candle excellent in decorativeness, which is not possible in the conventional one.

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

FIG. 1 is a sectional view of a candle according to the present invention, which is a storage portion B of a combustion agent storage body 2 having an opening A at the upper portion.
The gel-like combustion agent 1 is contained in the combustion core 3, and the combustion core 3 has a lower end supported by the support tool 4 at the bottom of the accommodation section of the combustion-agent container and a tip protruding from the upper surface L of the gel-like combustion agent. It stands upright. The above-mentioned combustion agent container 2 has an opening above the upper surface of the gel-like combustion agent, which does not impair the combustibility such as incomplete combustion caused by interruption of air supply to the flame of the combustion wick 3. Need to be provided. 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.

Further, the combustion agent container 2 is as shown in FIG.
It may be shaped so as to cover the upper flame of the combustion core 3.
In this case, one or a plurality of openings 5 for supplying air to the flame of the combustion core 3 must be provided above the upper surface L of the gel-like combustion agent so as not to impair the combustibility of the combustion core. . Further, it may have a structure of covering a container having an upper end opening, that is, a shape capable of being separated at the upper part of the upper 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 combustion agent 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.

A combustion wick that is usually used for a candle is applied to the combustion wick 3 which is erected in an upright state in the storage portion of the combustion agent storage body 2. 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 erected in an upright state from the bottom of the storage portion of the combustion agent storage body 2. 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, the lower end of which is supported by the support tool 4, is erected in an upright state on the bottom of the housing portion of the combustion agent housing 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 fine 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 so that the combustion wick stands upright. Furthermore,
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 accommodation portion of the combustion agent container to vertically set the combustion wick. In the combustion agent 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 material 11 such as iron or resin is adhered or adhesively fixed to the bottom of the accommodating portion of the combustion agent accommodating body 2, the combustion core is inserted through the metal support tool 4. 3 can be detachably attached to the bottom of the combustion agent accommodating 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 combustion agent storage section.

It is important that the flame of the combustion wick does not ignite the gelled combustion agent 1 contained in the accommodation section of the combustion agent container during combustion, and since the candle is mainly used indoors It is desirable to use odorless soot that does not generate soot. The lower limit of the flash point depends on the shape of the combustion agent container, for example, the size of the upper opening and the depth of the accommodation portion of the combustion agent container, but the depth of the accommodation portion of the combustion agent container such as wine glass is compared. For deeper ones, those having a temperature of 150 ° C. or higher are usually preferably used. On the other hand, in the case where the liquid container has a shallow container, it may not ignite even if a gel-like combustant having a flash point of about 120 ° C. is used.

The gel-like combustion agent used in the candle of the present invention is a liquid combustion agent gelled with a specific gelling agent. Such liquid combustion agents include butyl oleate,
Aliphatic monobasic acid ester such as glycerin monooleate, dibutyl adipate, di-n-adipate
Hexyl, diisononyl adipate, di-2 adipate
-Ethylhexyl, dialkyl adipate 610, diisodecyl adipate, dibutyl diglycol adipate, di-2-ethylhexyl azelate, dibutyl sebacate, diethyl sebacate diethyl ester, etc., triethylene glycol di-2
-Oxyacid esters such as ethyl butyrate, methyl acetylricinoleate, butyl acetylricinoleate, tributyl acetylcitrate, oils and fats such as soybean oil, cottonseed oil, rapeseed oil, castor oil, olive oil, safflower oil, whale oil, isostearic acid, etc. Examples thereof include saturated higher fatty acids, saturated higher alcohols such as isostearyl alcohol, n-paraffins, liquid paraffins, saturated hydrocarbons such as hydrogenated polybutene, and the like, which may be used alone or in combination of two or more. 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 combustion agent 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.

As a gelling agent for gelling the liquid combustion agent, various known gelling agents were thoroughly investigated and confirmed by experiments. As a result, it was confirmed that the gelling agents used in conventional candles 12-Hydroxystearic acid is used as a gelling agent for solving all of the problems, that is, generation of offensive odor such as amide odor during combustion, inclusion of nitrogen oxides in combustion gas, generation of soot, and offensive odor generated during fire extinguishing. It has been found that there is no other suitable gelling agent for candles used indoors, which is optimal.

Such 12-hydroxystearic acid can be made into a gel-like combustion agent by adding it to the above liquid combustion agent, heating and melting it, and then returning to room temperature. The amount of 12-hydroxystearic acid added to the liquid combustion agent depends on the properties such as the polarity of the liquid combustion agent, but the transparency of the gel combustion agent and the need for gelling strength to withstand normal storage and transportation. Usually, 1 to 3% by weight is suitable. If it is less than 1%, gelation will be poor, and if it exceeds 3%, the gelled combustion agent becomes cloudy and the transparency is impaired. Preferably, the added amount is 1.5 to 2.5% by weight. Furthermore, gel reinforcing agents such as fatty acid sodium and sodium carbonate and thickening agents such as highly viscous polybutene may be added to such an extent that the flammability is not hindered. Further, it is preferable to add a coloring agent to the gel-like combustion agent so that the color of the combustion agent can be enjoyed. With respect to the color of such a combustion agent, the more transparent the gel-like combustion agent is, the clearer the color of the colorant is, which is desirable. Moreover, you may contain an aromatic, a coloring agent, and a deodorant.

Experimental Examples 1, 2 and 3 and Comparative Examples 1 and 2 As a gel-like combustion agent container, an opening diameter of 40 mm and a depth of 3
Using 5 commercially available cylindrical glass cups of 0 mm in volume and 35 ml in capacity, a cotton wick for a candle was held as a burning wick by the circular burning wick support shown in FIG. 3 (a), and then placed on the bottom of the burning agent containing portion of the glass cup. I placed it. As a gel-like combustion agent, diisononyl adipate, polybutene and 12-hydroxystearic acid having the following composition were heated and melted and poured into the housing portion of the glass cup, and the mixture was returned to room temperature and gelled. , Gelling strength was confirmed.

Experimental Examples 4 and 5 and Comparative Examples 3 and 4 12 commercially available wine glasses having an opening diameter of 40 mm and a depth of 55 mm and a volume of 48 ml were used as a combustor container, and each of them was divided into 4 groups of 3 dioctyl adipate, n. -Paraffin 3
And dioctyl adipate 7 vol., N-paraffin, n-paraffin 6 vol. And dioctyl adipate 4 vol. 30 ml of b, c, and d were poured, the combustion core held by the steel circular combustion core support was placed at the bottom of the combustion agent accommodating part of the wine glass, returned to room temperature, gelled, and then ignited to burn in the combustion process. The presence or absence of ignition of the core flame to the combustion agent was observed. In addition, in any of the experimental examples and the comparative examples, a strange odor during combustion, soot,
There was no strange odor when extinguishing the fire.

Experimental Example 6 Two commercially available wine glasses C each having an opening diameter of 40 mm, a depth of 55 mm and a volume of 48 ml were used as a combustion agent container, and one wine glass D having a magnetic material adhered and fixed to the bottom of the container was used. The combustion core held by the steel rectangular core support shown in FIG. 3 (b) is arranged or magnetically adhered to the bottom of the accommodating portion, and diisononyl adipate (flash point 220 is used as a gel-like combustion agent.
30% of 12-hydroxystearic acid heated and melted at a temperature of 2.5 ° C) was poured into the mixture, and the mixture was returned to room temperature and gelled. When ignited, no foul odor or soot was generated. , Showed good flammability. Further, the gelled combustion agent gradually became liquid from the upper surface due to the radiant heat of the combustion core flame, and the entire combustion agent became liquid in about 1 hour. Furthermore, after about 3 hours when the combustion agent was halved, one wine glass C and one wine glass D were tumbled on a table cloth made of pure cotton, and as shown in FIGS. 8 (a) and 8 (b), the combustion agent was stored in the container. Although it spilled out of the body containing part at once, the combustion flame part stopped in the containing part and self-extinguishing was confirmed in about 10 seconds. At that time,
In D, the combustion wick support is magnetically attached to the bottom of the combustion-agent-accommodating-body accommodating portion, so that the combustion flame portion and the combustion agent are completely separated at the time of a fall, thereby enabling rapid self-extinction of the combustion wick flame. Therefore, the safety against fire will be further enhanced. Also, the remaining candles in wine glass C self-extinguished after 5 hours and 48 minutes due to exhaustion of the combustion agent.

Experimental Example 7 and Comparative Examples 5 and 6 The lower limit of the flash point required for the gel-like combustion agent for a candle of the present invention is the opening diameter of the liquid container containing part used,
Depends on the shape such as depth and capacity. Therefore, n-paraffin (flash point 120 ° C.) should be adjusted to 1.8% by weight so that 1
The presence of ignition of the burning core flame in the combustion agent during the combustion process by putting the gel-like combustion agent, which was made by heating and melting 2-hydroxystearic acid to the room temperature, and gelling it into three containers each of the following three shapes I checked.
