Description

  The present invention relates to a candle and a method for manufacturing the candle, and more particularly to a candle having a large outer diameter and capable of adjusting a combustion time and suppressing generation of oil smoke during combustion, and having a low flow wax and a method for manufacturing the candle. .

In recent years, candles with a long history have been increasingly used decoratively at events. For example, many candles are used in the remaining lantern festivals, lanterns or lanterns, or in the lanterns at shrines and temples. In addition, many candles are used to produce the light effects of the show at outdoor entertainment recitals and theatrical events.
As a candle for outdoor events, it is hard to disappear even if the wind blows, and it can be used safely, and it is composed of a burning agent composed mainly of wax and a burning core woven with cotton yarn, and the burning core is a hollow cylinder There is disclosed a candle that is configured in a shape and configured such that a combustion core can move in a through hole provided in a combustion agent (Patent Document 1). This candle has an effect that it is difficult to be extinguished by wind in the outdoors by burning a hollow cylindrical combustion core.
However, this candle is a cylinder with a thick combustor, and the hollow cylindrical combustion core may cause the candle flame to burn into a cylindrical shape, which may not be the conventional candle flame. There is a problem that there is. Furthermore, depending on the wind direction and the like, there is a problem that uniform combustion of the combustion core in a cylindrical shape is difficult, or that oily smoke is likely to be generated. In this candle, the combustion agent and the combustion wick are separated from each other, so that there remains flaming residue on the combustion wick, or a flow wax that is a phenomenon that the combustion agent remains without burning on the outer periphery of the candle body. There is a problem that the time cannot be adjusted.

  Further, in the case of the large candle No. 60 having dimensions of an outer diameter of 34 mmφ × height of 315 mm and an overall weight of about 225 g, the burning time of the candle is 20 to 22 hours. However, with the diversification of candle usage, the outer diameter and height are maintained, and the combustion time is about 1 hour, or the combustion time is controlled or the occurrence of flow wax is suppressed. There is a need for large candles that can be used.

  In addition, in the case of candlestick No. 1.5 for tomb visits with an outer diameter of about 9mmφ x 110mm in height, it prevents the candle flame from disappearing when the wind is strong in front of the tomb or the candle flame from disappearing. If the combustion wick is made thicker, oily smoke is likely to be generated.

JP 2000-328090 A

  The present invention has been made in order to cope with such a problem. Although the candle is a thick candle having a large outer diameter, the combustion time can be adjusted and the generation of oil smoke at the time of combustion can be suppressed, and the flow wax can be reduced. An object is to provide a candle that can be produced and a method for producing the candle.

The candle of the present invention comprises a molded combustion agent and a combustion core of a cylindrical body using nonwoven fabric, woven fabric, knitted fabric, or paper fixed in the combustion agent, and has a height of 500 mm or less and an outer diameter. Is a candle of 75 mm or less, and the combustion agent is formed into a cylindrical body having a value of (cylinder thickness / cylinder outer diameter) of 0.04 to 0.25, Is characterized by being contained and fixed in the cylindrical body concentrically with the cylindrical body. In particular, the outer diameter of the candle is 9 mm to 75 mm.
Further, the combustion agent is characterized in that the tip combustion part of the cylindrical body is formed in a tapered shape, and the combustion core is gathered at the tip combustion part and exposed from the combustion agent. .
In particular, the non-woven fabric, woven fabric or knitted fabric has a woven or knitted structure having an asymmetric structure in the circumferential direction of the cylinder.
The candle of the present invention is characterized by having a plug at the bottom of a cylindrical body that is a combustion agent.
Moreover, the candle of the present invention is characterized in that the cylindrical body as the combustion agent is cylindrical.

The method for producing a candle of the present invention is a method for producing the above-mentioned cylindrical candle,
Covering the non-woven fabric, woven fabric, knitted fabric or paper so as to form a cylindrical body on a columnar mold having a flange portion at the base portion;
The open end of the cylindrical mold that can form a cylindrical body having a value of (thickness of the cylinder / outer diameter of the cylinder) of 0.04 to 0.25 is fitted to the base of the columnar mold. Process,
Injecting a molten combustion agent into a gap formed between the columnar mold and the cylindrical mold;
And a step of removing the columnar mold and the cylindrical mold.

The candle of the present invention has a structure in which the thickness of the cylinder is within a predetermined range and a structure in which the cylindrical body is reinforced with the combustion core because the combustion core is concentrically contained in the cylindrical body. Become. Therefore, even when the outer diameter of the candle increases, the candle does not fall down during combustion, and the combustion time can be arbitrarily controlled by adjusting the thickness of the cylindrical body. The combustion wick enables a large flame like a torch and can suppress the occurrence of flow wax and oil smoke on the surface of the candle.
In particular, by using a non-woven fabric, a woven fabric or a knitted fabric in which the combustion core is a cylindrical body, uniform combustion can be achieved, the number of candles can be reduced, and flow flow to the surface layer can be suppressed.

It is a perspective view of a candle. It is AA sectional drawing in FIG. It is BB sectional drawing in FIG. It is a figure which shows a manufacturing process. It is a figure which shows another manufacturing process. It is a figure which shows the generation | occurrence | production situation of the soot of Examples 17-21 and Comparative Example 2. FIG. It is a figure which shows the generation | occurrence | production situation of the soot of Examples 22-26 and Comparative Example 2. FIG. It is a figure which shows the flow low situation of Example 17 and Comparative Example 2. FIG.

The candle of the present invention is shown in FIG. 1 is a perspective view of a candle, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB in FIG.
As shown in FIGS. 1 to 3, the candle 1 includes a cylindrical body, for example, a combustion agent 2 formed in a cylindrical shape, and a combustion core 3 fixed in the combustion agent 2 so as to be cylindrical. It is comprised from the stopper 4 which plugs up the bottom part of the candle 1. FIG. The molded combustor 2 is composed of a cylindrical body 2a that is a main body part and a tip combustion part 2b that is formed into a tapered shape, and a combustion core 3 is integrally fixed inside the combustor 2. . The combustion core 3 is gathered from the tubular body 2a to the front combustion part 2b according to the shape of the combustion agent 2 from the tubular body into one aggregate, and the front end part 3a is exposed from the front combustion part 2b.
At the bottom of the cylindrical body 2a, a stopper 4 having a hole 4a adapted to the pin shape of the candlestick is fitted.

  As a material of the molded combustible agent 2, a material conventionally used as a combustible agent for candles such as paraffin wax, fischer tropic wax, natural gas wax, polyethylene wax, plant wax, beeswax or the like alone or Can be used as a mixture. Among these, those containing vegetable higher fatty acids as the main component are suitable for the present invention. Since plant higher fatty acids can maintain the mechanical strength as a candle even if the thickness of the cylindrical body 2a is reduced, the thickness of the candle and the thickness of the cylinder of the present invention are arbitrarily adjusted. The burning time of the candle can be adjusted easily. Moreover, vegetable higher fatty acids do not generate an unpleasant odor during candle burning, and can suppress discoloration (yellowing) and generation of smoke during combustion.

The vegetable higher fatty acid is preferably a saturated fatty acid having 12 to 18 carbon atoms. For example, myristic acid (14 carbon atoms, melting point 54 ° C.), palmitic acid (16 carbon atoms, melting point 63 to 64 ° C.), stearin Saturated fatty acids such as acid (18 carbon atoms, melting point 69-70 ° C.), arachidic acid (20 carbon atoms, 77.5 ° C.), oleic acid (18 carbon atoms), linoleic acid (18 carbon atoms), linolenic acid (carbon) A highly hydrogenated product of unsaturated fatty acid such as Eq. 18) can be used.
Further, higher vegetable fatty acids and / or higher fatty acid glycerides can be contained as accessory components. Any higher alcohol or higher fatty acid glyceride can be suitably used as long as it is conventionally used for candle production. Specifically, higher alcohols: alcohols having 16 or more carbon atoms such as stearyl alcohol and cetyl alcohol, higher fatty acid glycerides: stearic acid glycerides, palmitic acid glycerides, myristic acid glycerides, lauric acid glycerides, oleic acid glycerides, linoleic acid glycerides, etc. The fatty acid glycerides having 12 or more carbon atoms and the like can be exemplified, and one or more of them can be selected and used.

The shape of the molded combustion agent 2 can be used if the cylindrical body 2a is cylindrical. The inner peripheral surface 2c and the outer peripheral surface 2d of the cylindrical cross section shown in FIG. 2 can be used in any of a cylindrical shape such as a perfect circle, an ellipse, and a deformed circle, or a rectangular tube shape such as a triangle, a quadrangle, a hexagon, and a polygon. . Even if the inner peripheral surface 2c and the outer peripheral surface 2d of the cylindrical body have the same shape or different shapes, they can be used. For example, the inner peripheral surface 2c can be a true cylinder, and the outer peripheral surface can be a spiral cylindrical body.
A preferable cylindrical cross section of the present invention is a cylindrical shape in which the inner peripheral surface 2c and the outer peripheral surface 2d are concentric, and more preferably a concentric circular cylinder. A uniform combustion flame can be obtained by using a concentric circular cylinder. In addition, the mechanical strength of the candle is improved, for example, it does not break even if the cylinder is thin. The cylinder may have a tapered shape that tapers in the direction of the candle tip.
By making the shape of the combustion agent 2 cylindrical, it is possible to control the amount of wax dissolved within a unit time and to prevent flowing wax. Furthermore, even if the combustion balance is lost due to an unexpected wind or the like, the wax flows into the cylinder, so that a large amount of flow wax does not occur.

The tip burning part 2b of the combustion agent 2 has a shape that is tapered from the circumference of the cylindrical body 2a, and the cylindrical combustion core 3 is continuously connected to the tip burning part 2b from the cylindrical body 2a. The assembled combustion core 3 is exposed from the tip combustion portion 2b.
The tapered shape of the tip burning part 2b of the candle is not particularly limited as long as it can enclose the combustion core 3, and a well-known candle shape can be used.

  The plug 4 fitted into the bottom of the cylindrical body 2a is preferably made of the same material as that composing the combustion agent 2, and has a hole 4a that matches the pin shape of the candlestick. By fitting the stopper 4, it is easy to install on the candlestick, and the mechanical strength of the candle is improved. In addition, the use of candles can be expanded by preparing a variety of plugs that can accommodate various candlestick shapes.

The combustion agent 2 formed into a cylindrical body has a value of (thickness of the cylinder / outer diameter of the cylinder) in the range of 0.04 to 0.25. Here, the outer diameter of the cylinder represents the maximum outer diameter of the cylinder, and the thickness of the cylinder represents the minimum thickness. Further, the thickness of the cylinder is a thickness including the combustion core.
In the case of the cylindrical combustion agent 2, as shown in FIG. 2, if the wall thickness of the cylinder having a cylindrical cross section is t and the outer diameter of the combustion agent 2 is T, (t / T) = 0.04. ˜0.25, preferably (t / T) = 0.05˜0.20. When (t / T) is less than 0.04, the thickness t becomes too thin, so that it becomes difficult to hold the combustion core, and the candle is easily broken, so that the mechanical strength cannot be maintained. When (t / T) exceeds 0.25, the wall thickness t becomes too thick, and it becomes difficult to adjust the combustion time. The wall thickness t is expressed by (outer diameter−inner diameter) / 2.

As for the size of the candle, it is preferable that the height h of the candle is up to about 500 mm and the outer diameter T is up to about 75 mm.
If the size of the candle is within this range, it will not break during use as a candle for use in events, etc. and has sufficient mechanical strength, and it will burn out in minutes to hours, etc. Is possible. In addition, advertisements and event names can be displayed clearly and clearly on the outer surface of the candle.

  Moreover, in the case of a candle for grave visit, it is preferable that the candle has a height h of about 100 mm and an outer diameter T of about 9 mm. In the cemetery candle, the flame may disappear due to wind or the like in front of the grave, but by making the combustion core 3 (described later) into a cylindrical shape, the flame does not disappear stably and no oil smoke is generated.

As the combustion core 3, a non-woven fabric, a woven fabric, or a knitted fabric that is a cylindrical body can be used. The cylindrical body can be obtained by, for example, winding a tape-shaped nonwoven fabric or the like in a spiral. In the case of winding in a spiral, the end portions in the width direction of the tape may be butted or overlapped, or the end portions in the width direction of the tape may be provided with a predetermined interval. Or the width direction edge parts, such as a wide nonwoven fabric, can be faced | matched and piled up to a cylindrical body.
When a woven fabric or a knitted fabric is used as the burning wick 3, the burning wick 3 can be a continuous long tubular woven fabric or a tubular knitted fabric. The cylindrical woven fabric can be manufactured by a cylindrical loom, and the cylindrical knitted fabric can be manufactured by a seamless knitting machine.
By using a seamless cylindrical long object, uneven melting of the combustion agent does not occur at the time of combustion, and the combustion agent liquefaction and combustion suction balance are not lost. As a result, the number of candles can be reduced and flow wax can be prevented.
The combustion core 3 of the present invention is preferably a tubular knitted fabric. By using a knitted fabric, it is easy to make a seamless cylindrical long product, and the structure can be kept long even after the core 3 is carbonized by combustion, so that stable combustion can be maintained.

As a material that can be used for the combustion core 3, natural vegetable fibers such as cotton and hemp yarn and regenerated fibers such as rayon can be preferably used.
The tubular woven fabric or tubular knitted fabric in the present invention is preferably a tubular fabric of weaving or knitting that is partially different in the circumferential direction of the tube. For example, a woven structure or a knitted structure having an asymmetric structure can be obtained by knitting a part of the circumferential direction more densely than other parts.
Specifically, an asymmetric structure can be obtained by using a vertical Lilian knitting machine.
By adopting an asymmetric structure, for example, the combustion speed changes at a sparsely or densely woven or knitted part, so that the combustion core 3 is bent at an appropriate angle during combustion, and a part of the combustion core 3 appears outside the combustion flame. As a result, it easily reacts with oxygen outside the flame, and the combustion core 3 becomes ash and easily disappears.

As the combustion core 3, paper can be used as a cylindrical body in addition to the nonwoven fabric, woven fabric or knitted fabric.
Paper is a thin sheet of plant fiber that is not woven. Examples of the plant fiber include pulp collected from wood, Mitsuma, Kozo, Ganpi, hemp, cotton, linter, Manila hemp, esparto, straw, bamboo, bagasse, kenaf, waste paper and the like.
As paper varieties, Japanese paper that does not use additives or bleaching agents is preferred. Japanese paper uses bast inside the bark, and examples of Japanese paper include Mino paper, Tosa paper, a special use or name of a memorandum paper, a bird's child paper, and a half paper. Since Japanese paper is mainly composed of cellulose, it does not contain components harmful to the human body and can burn without generating smoke. The paper used as the combustion core 3 of the present invention is preferably a donation paper because there is little combustion residue.

  Moreover, paper can be wound around the outer periphery of the candle of the present invention. The Japanese paper is preferred as the paper.

The candle manufacturing method of the present invention will be described with reference to FIG. FIG. 4 shows the manufacturing process.
As shown in FIG. 4A, a columnar mold 5a and a cylindrical mold 5b are prepared. The mold 5 a has a thickness that defines the inner diameter and height of the candle 1. The mold 5b has a cylindrical shape in which one open end is fitted to the base portion 5c of the mold 5a, has an inner diameter that defines the outer diameter of the candle 1, the size of the outer diameter of the mold 5a and the mold 5b. The thickness of the cylinder of the cylindrical body 2a can be adjusted by the difference from the size of the inner diameter.
As shown in FIG. 4 (b), the tubular woven fabric or tubular knitted fabric 3 is placed on the mold 5a while expanding the stitches and the like, and the shape of the combustion core 3 is adjusted. In this case, the combustion core 3 can be formed by winding a non-woven tape in a spiral shape.
As shown in FIG. 4 (c), after the metal mold 5b is fitted to the metal mold 5a, the combustion agent 2 that is heated to the gap between the metal mold 5b and the metal mold 5a is injected.
As shown in FIG.4 (d), the cap 6 is put on the head of the metal mold | die 5b, and the shape of the combustion front-end | tip part of a candle is adjusted. Then cool down.
The candle 5 shown in FIG. 4E is completed by removing the mold 5b, the mold 5a, and the cap 6 and fitting the prepared stopper 4 into the bottom.

Although the candle of the present invention is a thick candle, the burning time can be adjusted such that it burns in a short time. Moreover, since it is a thick candle, it is easy to display various prayers on the outer surface of the candle, and it can be easily recognized. In addition, a large flame like a torch can be produced while suppressing the generation of flow wax and oil smoke.
For this reason, the candle of this invention can be utilized in order to produce light effects, such as various events. In addition, it can be used as a candle for the Mannen Festival, Mannen-toen, Mannen-Nan-San, or Mannen Recreation Society.

A method for producing a universal candle, which is a small candle according to the present invention, will be described with reference to FIG. FIG. 5 is a diagram showing a manufacturing process of a lantern candle. This lantern candle 1 'conforms to the Tomb Candle 1.5. The candle 1 ′ has a cylindrical shape with an outer diameter of 9.3 mmφ, an inner diameter of 6 mmφ, and a height of 100 mm, and has a paper core at a position of an inner diameter of 7.0 mmφ. The length of the paper core protruding from the combustion agent is about 10 mm.
As shown in FIG. 5A, a columnar mold 5a ′, a cylindrical mold 5b ′, and a wrapping paper 3 ′ to be a cylindrical paper core are prepared. The mold 5a ′ has a thickness that defines the inner diameter and height of the candle 1 ′. The mold 5b ′ has a cylindrical shape in which one open end is fitted to the base portion 5c ′ of the mold 5a ′, and has an inner diameter that defines the outer diameter of the candle 1 ′.
As shown in FIG. 5B, the wrapping paper 3 ′ is set on the mold 5a ′. By setting the inner diameter of the wrapping paper 3 ′ slightly larger than the outer diameter of the mold 5a ′, the wrapping paper 3 ′ can be easily set on the mold 5a ′.
As shown in FIG. 5 (c), the nonwoven fabric or thin paper is applied to the joint of the wrapping paper 3 ′ and fixed with the combustion agent 2. Note that this step can be omitted when the wrapping paper 3 ′ can be fixed by the combustion agent 2 at the stage of setting shown in FIG.
As shown in FIG. 5 (d), the mold 5b ′ is fitted into the mold 5a ′. After that, as shown in FIG. 5 (e), the combustion agent 2 that is heated and liquefied is injected into the gap between the mold 5b ′ and the mold 5a ′.
The mold 5b ′ and the mold 5a ′ are removed, and a separately prepared plug 4 is fitted into the bottom, thereby completing the universal light candle 1 ′ shown in FIG. 5 (f).

Examples 1-3
A candle having an outer diameter (T) of 26 mmφ, an inner diameter of 21 mmφ, a wall thickness (t) of 2.50 mm, and a height of 250 mm was manufactured using a cylindrical mold and a cylindrical mold. The combustion core used is shown in Table 1.
A combustion core was put on the cylindrical mold shown in FIG. In Examples 1 and 2, the shape of the cylindrical knitted fabric was covered with a cylindrical mold while adjusting the shape. In Example 3, a combustion core was wound around a cylindrical mold so as to form a continuous tubular nonwoven fabric.
A cylindrical mold was fitted into the cylindrical mold, and a liquid combustion agent was injected into the gap between the cylindrical mold and the cylindrical mold. Before the liquid combustion agent solidified, the top of the mold was covered with a cap to adjust the shape of the burning tip of the candle, and then cooled.
After removing the candle from the mold, a stopper molded in advance with the above-mentioned combustion agent was fitted into the bottom, and the candles of Examples 1 to 3 were obtained.

Comparative Example 1
A conventional cylindrical candle having an outer diameter (T) of 26 mmφ and a height of 250 mm was manufactured by a conventional method using a cylindrical mold. Since the candle is cylindrical, the thickness (t) defined in the present invention is 13 mm, which is half the outer diameter (T). Cotton thread was used for the combustion core.

The burning test of the candles obtained in Examples 1 to 3 and Comparative Example 1 was performed, and the soot coefficient and the presence or absence of flowing wax were measured. The results are shown in Table 1.
The soot coefficient was measured by this method using a measuring instrument used by the European Candle Industry Association (based on RAL-GZ 041). However, the distance between the soot-measuring glass surface and the tip of the candle was 40 cm and burned for 20 minutes. All examples and comparative examples were measured under the same conditions. The results are shown in Table 1. The presence or absence of flow wax was determined by observing the candle after measuring the coefficient of wrinkle.
The wrinkle coefficient was obtained by the following formula.

Soot coefficient = 100 × [1- (E ₁ / E ₀ )] × 60 / burning time (20 minutes)

Here, E ₁ represents the intensity of light transmitted through a glass plate with a ridge, and E ₀ represents the intensity of light transmitted through a clean glass plate without glazing.

Examples 4-30, Comparative Examples 2-4
Using a cylindrical mold and a cylindrical mold, candles having an outer diameter (T) of 32 mmφ, a wall thickness (t) of 1.50 to 6.00 mm, and a height of 250 mm were used in Examples 4 to 30 and Comparative Examples 3 and 4. Was produced in the same manner as in Example 1, and Comparative Example 2 was produced in the same manner as in Comparative Example 1, and 0.07 mm thick Japanese paper was wrapped around the obtained candle. Table 1 shows the thickness ratio and the combustion core used.
In the same manner as in Example 1, the soot coefficient and the presence or absence of flow wax were measured. The results are shown in Table 1. In Comparative Example 4, the thickness ratio was small, and molding as a candle was difficult. Therefore, the subsequent evaluation test was stopped.
Moreover, the generation | occurrence | production situation of the soot of Examples 17-26 and the comparative example 2 is shown in FIG. 6 and FIG. 7, and the generation | occurrence | production situation of the flow low of Example 17 and the comparative example 2 is shown in FIG. As can be seen in FIG. 6 and FIG. 7, it was also confirmed visually that each example had less wrinkles than Comparative Example 2. In addition, as shown in FIG. 8, the conventional candle clearly showed the occurrence of flow wax.

As a result of measuring the burning time in terms of the amount of combustion per hour, Example 17 (the weight of the candle was 116.2 g) was 47.4 g / h, and Example 18 (the weight of the candle was 91.8 g) was 50.4 g / h. Example 19 (the weight of the candle is 75.8 g) is 51.9 g / h, Example 20 (the weight of the candle is 51.7 g) is 63.9 g / h, and Example 21 (the weight of the candle is 40.0 g) ) Was 68.4 g / h, and the thickness ratio was small, that is, the thickness of the cylindrical candle was reduced, and the amount of combustion per hour increased, that is, the burning time of the candle could be shortened.
When the burning time of the candle is specifically compared, the burning time of Example 17 is 2.44 hours, the burning time of Example 18 is 1.82 hours, the burning time of Example 19 is 1.46 hours, and Example 20 The burning time was 0.81 hours, the burning time of Example 21 was 0.58 hours, and the burning time could be adjusted between 2.44 hours and 0.58 hours.
