Description

The present invention relates to a candle that can be used safely because it does not sag during use, and that has an excellent design effect.

Conventionally, the development of a candle that does not drip when in use has been one of the challenges of the industry, and several proposals have been made for this purpose. For example, a candle (Patent Document 1) in which a polyethylene film is wound around the entire outer periphery of a candle body and a candle (Patent Document 2) in which a synthetic resin thin film such as a polyester film is wound around the outer periphery of the candle body have been proposed.
Further, the applicant of the present application is provided with an amino resin, an acrylic resin, a urethane resin, a polyester resin, a polyvinyl chloride resin, a polycarbonate resin, a polyethylene, an outer peripheral surface of a combustion body including a combustion agent and a combustion core disposed inside the combustion agent. Rigidity and heat resistance that integrates plant fiber with synthetic resin selected from polyvinyl acetate, polypropylene, polyvinylidene chloride, polystyrene, polyvinyl alcohol, polyethylene terephthalate, 6-nylon, polytetrafluoroethylene, polyimide, and synthetic cellulose resin A candle (Patent Document 3) has been proposed in which a thin composite that is resistant to thermal deformation is attached and the light is seen through the composite.
Further, the candle is composed of a cylindrically shaped combustion agent and a combustion cylinder fixed to the outer periphery of the combustion agent, and the combustion cylinder is a laminated core in which sulfuric acid paper is disposed on the combustion agent side. A candle (Patent Document 4) is proposed in which the laminated core is laminated in the order of the first sulfuric acid paper, the nonwoven fabric, and the second sulfuric acid paper from the combustion agent side.

However, in a candle wrapped with a synthetic resin thin film such as polyester proposed in Patent Document 1 and Patent Document 2, the thin film is melted or thermally deformed by the heat of the combustion flame, and the molten wax flows down. The prevention effect is hardly expected.

Further, a thin composite excellent in heat resistance in which a synthetic resin and a vegetable fiber are integrated on the outer peripheral surface of a combustion body composed of a combustion agent proposed in Patent Document 3 and a combustion core disposed inside the combustion agent. Although the candle wrapped around the body has an excellent effect of preventing melting and dripping, it is difficult to separate the synthetic resin from the plant fiber when discarded after use. In addition, thin composites made by integrating commercially available flame-retardant synthetic resins and plant fibers are often disposed of as vinyl chloride resin films and Japanese paper as synthetic resins. The disadvantage is that dioxins are generated during incineration and that the burden on the environment during landfilling is large, and there is an urgent need to consider alternative materials.
Further, the candle of Patent Document 4 is for outdoor use intended to prevent dripping by using a laminated core laminated in the order of the first sulfuric acid paper, the nonwoven fabric, and the second sulfuric acid paper from the combustion agent side. It is a candle. The candle is likely to disappear under windy conditions because the oil-resistant sulfuric acid paper inhibits the supply of the melted combustible agent to the non-woven fabric that becomes the combustion core. Further, the combustion cylinder burns and disappears with the burning of the candle, which is completely different from the candle of the present invention.

Accordingly, an object of the present invention is to provide a candle having a good design effect, which uses a material / material with a low environmental load, does not drip a burning agent during use, and can be used safely.

The inventor has reached the present invention as a result of intensive studies to achieve the above object. That is, the first invention is a candle in which a flame-retardant oil-resistant paper is wound around the outer peripheral surface of a candle burning body composed of a combustion agent and a combustion core, and the second invention is a flame-resistant oil-resistant paper. 2. The candle according to claim 1, wherein the paper is tracing paper.

In the candle of the present invention, a flame-retardant oil-resistant paper having a low environmental load and having a biodegradability is wound around the outer peripheral surface of a candle burning body composed of a combustor and a combustion core. The oil-resistant paper functions as a molten wax flow prevention body that prevents dripping of the molten wax.

The flame-retardant oil-resistant paper in the candle of the present invention has rigidity and heat resistance, and has excellent heat resistance and heat deformation resistance compared to synthetic resin films and sheets, so that the molten wax can be reliably stored. It has excellent characteristics that it can. In other words, the molten solder flow prevention body composed of the flame-retardant oil-resistant paper can sufficiently function as a weir to prevent the molten wax from flowing down, and the candle of the present invention can be prevented from dripping. It is said. Furthermore, in a usage form in which the height of the prevention body is higher than that of the combustion flame, the prevention body also functions as a squirt, so that the combustion flame is difficult to disappear even when used under windy conditions. Demonstrates power in use. Further, in this case, since the molten solder flow prevention body already has a function of squirting, a container and a squirt for housing the candle are not required and can be used easily. The candle of the present invention is biodegradable even when used as a single-use product, and therefore has a low environmental impact, and there is no need to clean and care for containers and squirts after use, and the handling is extremely simple. Furthermore, by using a tracing paper excellent in transparency for the flame-retardant oil-resistant paper of the present invention, if a function that the light can be seen through the oil-resistant paper is given, a lantern is passed over the prevention body, A decorative effect tailored to the use atmosphere can be obtained easily and easily, such as enjoying a soft and warm light like a dim.

Next, an example of the candle of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a candle according to the present invention. A candle 4 is composed of a candle burning body 2 comprising a burning agent and a combustion core inserted and disposed inside the burning agent, and a flame retardant on the outer circumferential surface of the candle burning body. It is comprised from the molten solder | flow flow prevention body 3 which wound this oil-resistant paper. The molten solder flow prevention body 3 is wound so that the combustion flame 1 is not hidden. FIG. 2 is a perspective view showing another example of the candle according to the present invention. The flame-retardant oil-resistant paper is wound so that the molten wax flow prevention body 3 is higher than the combustion flame 1. ing. The candle in the form shown in FIG. 1 functions as a weir that prevents the molten wax flow prevention body 3 from flowing down, so that dripping of the combustion agent does not occur. In addition, the candle of the present invention in the form shown in FIG. 2 functions not only as a weir that prevents the molten wax from flowing down, but also prevents the combustion agent from dripping. Since it also functions as a sea squirt, the combustion flame will not disappear even when used under windy conditions, and it will be more effective for outdoor use. Become a candle.

The candle burning body 2 used in the present invention includes, for example, hydrocarbon compounds such as paraffin wax, higher fatty acids such as stearic acid, esters of higher fatty acids such as wood wax and beeswax and higher alcohols, and higher aliphatic alcohols such as stearyl alcohol. These are known candle burning bodies composed of a combustion agent mainly composed of biodegradable wax and a string-like combustion core mainly composed of combustible plant fibers. The shape and size of the candle burning body 2 is not particularly limited. However, the flame-retardant oil-resistant paper is wound around the outer peripheral surface of the candle burning body 2 and functions as a molten wax flow prevention body. In order to achieve this, a simple shape without many irregularities is preferable. For example, as shown in FIG. 3, a cylindrical shape, a prismatic shape, an inverted cone shape, a truncated cone shape, an inverted truncated cone shape, etc. are easy to install and use the flame-retardant oil-resistant paper on the candle burning body 2. This is particularly desirable due to the difficulty of thermal deformation at times.

The flame-resistant oil-resistant paper wound around the outer peripheral surface of the candle burning body 2 serves as a weir to prevent the molten wax from flowing down by the molten wax flow-preventing body 3 formed by the flame-resistant oil-resistant paper. In order to exhibit the function, it is necessary to have a characteristic that it has heat resistance, does not cause thermal deformation, and does not allow liquid to penetrate. Also, as shown in FIG. 2, the candle in a form wound so that the molten wax flow prevention body 3 is higher than the combustion flame 1 is lit by the light from the combustion flame 1 through a flame-resistant oil-resistant paper. It can be seen through and show the candle decoration effect. Moreover, it can be used as disposable, and it is desirable that the prevention body 3 itself can be easily handled at the time of production and can be produced at low cost.

In order to examine the characteristics that the molten solder flow prevention body 3 should have, when assuming paper as a material constituting the molten solder flow prevention body, the paper has rigidity and heat resistance and does not cause thermal deformation. However, on the other hand, since it has a characteristic of infiltrating the liquid, there is a possibility that the molten wax oozes out and flows down, sucks up the molten wax, and burns up by contact with the combustion flame.

On the other hand, assuming a synthetic resin as a material constituting the molten solder flow preventive body, the synthetic resin has the property of not allowing the liquid to permeate, so the molten wax does not ooze out and flow down, Generally, it is inferior in heat resistance, tends to cause thermal deformation, tends to cause drooping as a result of thermal deformation, becomes unsightly in appearance, and may burn or burn up in contact with a combustion flame.

For these reasons, flame retardant paper that does not penetrate the molten wax, that is, flame retardant oil-resistant paper, has rigidity and heat resistance and is less likely to be thermally deformed. It has been found that the molten solder flow prevention body 3 that can be stored is a material having all the characteristics required.

The oil-resistant paper referred to in the present specification is not particularly limited as long as it is a paper made of a biodegradable pulp that does not permeate, exude, or suck up molten wax. If the fine gaps between the cellulose fibers of the paper are reduced or eliminated to such an extent that the molten wax does not penetrate, the paper does not exude or suck up the molten wax, that is, oil-resistant paper.

For example, it is called densification, and the paper is struck well to make paper and smooth the surface to reduce the gap. For example, the surface of the cellulose fiber is gelled and swollen with glassine paper or sulfuric acid called chemical modification. For example, parchment paper, sulfuric acid paper, pseudo-parchment paper, etc., and oil-resistant paper called impregnation that fills the gaps by impregnating oil or resin having a refractive index close to that of cellulose.

In particular, among oil-resistant papers, tracing paper is excellent in permeability, and when it is used as the material of the flame-retardant oil-resistant paper of the candle of the present invention, it is excellent in the effect of lighting lighting such that the combustion flame is transparent.

Unlike general paper quality, tracing paper has excellent transparency, so if you overlay multiple patterns and patterns, the bottom pattern and patterns can be seen through, so you can expect an overlapping effect, Also called hot stamping, it is roughly divided into stamping and heat-resistant rubber banding. Tracing paper can be applied with special colors such as gold and silver as well as corporate colors. There are various printing characteristics such as mirror surface, hairline, wood grain, hologram and pearl. In addition, when tracing paper is embossed or streaked, unlike ordinary paper, the unique texture and variety of expressions can be achieved by taking advantage of the fact that the part becomes cloudy.

The material, material, thickness, etc. of the oil-resistant paper, which is a constituent material of the molten solder flow prevention body 3, are the combustion amount per unit time of the candle combustion body 2, the distance between the combustion flame 1 and the prevention body 3, and the If the prevention body 3 is appropriately selected in accordance with the use conditions in consideration of the heat resistance required in various usage forms such as heat build-up when the function as a squirt as shown in FIG. 2 is added Good.

For example, if it is a commercially available tracing paper, the thickness is not particularly limited as long as the required rigidity can be ensured. However, if the tracing paper has a thickness of less than 40 μm, the rigidity is poor and the surface is easily affected by moisture. May be unfavorable for use. On the other hand, when the thickness is increased, the translucency is reduced and the cost is increased. Therefore, a thickness of about 70 μm to 200 μm is usually preferable, and a tracing paper having a thickness of about 100 μm to 150 μm is more preferably used.

Furthermore, from the viewpoint of printing characteristics, there is a thickness that can be applied by printing means. For example, printing can be performed with a thickness of about 80 μm or more for laser printer printing and about 100 μm or more for inkjet printer printing. Therefore, since it can be printed with a commercially available laser printer or inkjet printer without depending on the printer, it is possible to deal with a small amount of printing and original printing.

Next, as a technique for making the oil resistant paper flame retardant, a known technique can be used, and there is no particular limitation as long as the oil resistant paper can be made flame retardant or incombustible. For example, apply, spray, impregnate, infiltrate, and internally add flame retardants such as antimony compounds such as antimony trioxide, organic or inorganic phosphoric acid, nitrogen-containing compounds, halogen-based, aluminum hydroxide, guanidine-based compounds. Add flame retardant or non-flammability.

The means for forming the molten solder flow prevention body 3 by winding a flame-retardant oil-resistant paper around the outer peripheral surface of the candle-burning body 2 is a flame-retardant oil-resistant paper on the outer peripheral surface of the candle-burning body 2 formed in advance. And is fixed with a known sticking or bonding means, or the flame-resistant oil-resistant paper is formed in advance with the known sticking or bonding means to form the molten solder flow prevention body 3 and The molded candle burning body 2 may be inserted and fixed. At this time, the flame-retardant oil-resistant paper may be wound around the outer peripheral surface of the candle burning body in multiple layers. As a result, required conditions such as heat resistance and rigidity may be obtained. If necessary, the candle burning body 2 and the molten solder flow prevention body 3 may be adhered or bonded and fixed.

As a means of adhesion or adhesion, a known method can be used, for example, rubber-based, acrylic-based, silicone-based pressure-sensitive adhesives, or thermosetting resin-based, thermoplastic resin-based, rubber-based, composite systems thereof, What is necessary is just to select suitably from the adhesive materials, such as a hot-melt type, a starch type, a polyvinyl alcohol type, an ether type, and an ethylene-vinyl acetate resin emulsion type, in consideration of the constituent material of the molten wax flow prevention body 3 and the like.

It is desirable that the molten solder flow preventive body 3 is attached as closely as possible to the outer peripheral surface of the candle burning body 2. There is a gap between the candle burning body 2 and the molten solder flow prevention body 3 during installation, or the molten solder flow prevention body 3 is deformed after installation or during use, and between the candle combustion body 2 and the molten wax flow prevention body 3. When a void is formed in the gap, there is no problem if the void is small enough to cool and solidify in the process where the molten wax flows down the void, but if the void is larger than that, the molten wax flows down from the void. Will cause inconvenience.

The molten solder flow prevention body 3 does not necessarily have to be wound around the entire outer peripheral surface of the candle combustor 2, and if limited to a predetermined combustion time, for example, as shown in FIG. It may be only.

In the present invention, the candle mounted in such a manner that the molten wax flow prevention body 3 is higher than the combustion flame 1 has an excellent function that the combustion flame is difficult to disappear even when used under windy conditions. It is suitable for outdoor use. For example, if used for outdoor use such as lanterns, lanterns and candles for grave visits as shown in FIG. 5 and FIG. 6, no other candle containers or squirts are required and can be made disposable and easy to use. . In addition, the use of spirit flow as shown in Fig. 7 also prevents the flame from disappearing due to the wind, and it is a fantastic and ghostly atmosphere that the flame swaying over the molten wax flow prevention body drifts in the flow of the river. The effect that is not found in conventional candles can be obtained easily and easily. FIGS. 8 to 10 are examples of the usage pattern of the candle of the present invention, and a decorative effect suitable for each scene such as a Japanese-style use atmosphere or a gorgeous place can be obtained simply and easily.

In addition, a desired color and pattern can be added to the candle melt-flow prevention body 3 of the present invention, or a design, characters, and the like can be added by known means such as writing, printing, and transfer. In particular, commercially available tracing paper is rich in color variations and pattern variations, with a lineup of thin to special thickness grades, and you can choose any material that suits the usage atmosphere, Decoration effects such as a feeling of relaxation and a solemn atmosphere can be obtained simply and easily.

Next, the candles of the present invention will be specifically described with reference to Examples and Comparative Examples shown in Table 1.

As materials for the molten solder flow prevention bodies of Examples 1 to 4 and Comparative Examples 1 to 3, tracing paper having a cut size (60 mm × 158 mm) and a commercially available thickness of 40 μm, 80 μm, 110 μm, and 200 μm as oil-resistant paper, A commercially available high-quality paper for an ink jet printer having a thickness of 100 μm and a white turbid vinyl chloride resin film having a thickness of 150 μm were prepared.

It should be noted that the flameproofing of the oil-resistant paper of the molten solder flow prevention body material of Examples 1 to 4 and the flameproofing of the high-quality paper of Comparative Example 2 were performed using purified water with Nonnen 600 (Maruhishi Oil Chemical Co., Ltd.). What was dried for 5 minutes after impregnating in the flame-retardant treatment liquid diluted twice was made into the flame-retardant oil-resistant paper and the flame-resistant high-quality paper.

We prepared 21 cylindrical candle burning bodies with a diameter of 47 mm and a height of 40 mm, which consisted of a paraffin-based combustion agent and a cotton core. Of these, the outer peripheral surface of each of the three candle burning bodies had a thickness. 40 μm, 80 μm, 110 μm, and 200 μm tracing paper was flame-treated. Next, the flame-resistant oil-resistant paper is tightly wound so that the upper end of the flame-resistant paper is 20 mm above the upper end of the candle burning body as shown in FIG.
A sample of Examples 1 to 4 was prepared by bonding and fixing with a commercially available starch-based adhesive to obtain a molten wax flow-prevention body.
Further, each of the three candle burning bodies is wound with the above-mentioned non-incombustible 110 μm-thick tracing paper and flame-retardant treated flame-resistant fine paper in the same manner as in the example sample, and adhesively fixed with a commercially available starch-based adhesive. Comparative Example 1 and Comparative Example 2 were used as samples. Further, a cloudy vinyl chloride resin film having a thickness of 150 μm was wound around the above three candle burning bodies in the same manner as in the example sample and adhered and fixed with a vinyl chloride resin adhesive to obtain a comparative example 3 sample.

These example samples and comparative example samples were used, arranged at intervals of 15 cm, and after igniting the combustion core, the swing of a domestic electric fan placed at a distance of about 3 m from the sample and a maximum of about 0.5 m / second Each sample was burned for 5 hours under air blowing at a wind speed, and the combustion characteristics and the sagging state of each sample were observed.

All the samples of the examples were free from thermal deformation of the molten brazing flow preventive body over the course of combustion for 5 hours, and the molten wax did not sag at all and maintained good combustion conditions. However, although the melt brazing flow preventive body of Example 1 is 40 μm in thickness and is slightly wrinkled due to the heat trap of the combustion flame, the preventive body of Example 2 is slightly wrinkled, There was no problem at all as a function of the molten brazing flow preventing body.

In addition, since the flame-retardant oil-proof paper, which is the material of the melt-waxing prevention body of each sample of the example, is a tracing paper with excellent permeability, the effect of allowing the light to pass through has been confirmed. Was thick tracing paper of 200 μm, so it was found that the effect of the light is slightly reduced.

After 5 hours of burning, each of the three samples of the example was tested for flame retardancy by contacting the flame of a lighter for 2 seconds with the upper ends of all the melt-waxing prevention bodies. All formed self-extinguishing within 1 second although they formed flames. Therefore, even if a combustion flame comes close to and comes into contact with the molten braze flow preventive body, the molten braze flow preventive body is made inflammable to ignite and burn the molten braze flow preventive body. Will not occur, ensuring safety against fire.

Moreover, since the comparative example 1 sample uses the same non-incombustible tracing paper having a thickness of 110 μm as the material of the molten solder flow preventive body of the example 3 sample, the same 3 samples as the example 3 sample. In all cases, there was no thermal deformation of the molten solder flow preventive body through the combustion for 5 hours, and the molten wax did not sag at all and maintained a good combustion state.
However, when the lighter flame was brought into contact with the upper end of the melt-waxed flow preventer after burning for 5 hours, the flame spread. However, due to the oil-resistant paper, no combustion behavior due to sucking up the molten wax was observed. Therefore, if the combustion flame comes close to the molten brazing flow preventing body and comes into contact with the molten brazing flow preventing body, it is expected that the molten brazing flow preventing body will ignite and burn, thereby making the oil resistant paper flame retardant. Therefore, safety against fire can be secured.

In addition, the sample of Comparative Example 2 was the same as the sample of the example, but all the three samples did not undergo thermal deformation of the flame retardant fine paper of the molten wax flow preventive body through the combustion process for 5 hours. The situation of oozing from the surface was observed. Further, when a lighter fire was brought into contact with the upper end of the molten wax flow preventive body after burning for 5 hours, it was observed that the high-quality paper sucked up the molten wax and burned up despite being flame retardant. Therefore, if the combustion flame comes close to and comes into contact with the molten braze flow preventing body, the molten braze flow preventive body may act as a combustion core to suck up the molten wax and burn it up.

Furthermore, in the sample of Comparative Example 3, one of the three samples started to heat deform the cloudy vinyl chloride resin film from 1 hour after the start of combustion, and 3 hours and 30 minutes later, all three candles showed heat deformation. In particular, two of them were severely thermally deformed, and finally one of them covered the upper part of the combustion flame, and the flame disappeared. As a result of severe thermal deformation of the remaining two white turbid vinyl chloride resin films after the lapse of about 3 hours, one sample observes the situation where the molten wax leaks, and the remaining one sample comes into contact with the combustion flame. I finally got burnt.

The candle in which the flame-retardant oil-resistant paper is wound around the outer peripheral surface of the candle burning body of the present invention, the flame-retardant oil-resistant paper has biodegradability, rigidity, and heat resistance, and exhibits heat deformation resistance. Therefore, it is a safe candle that does not drip the combustion agent that can reliably store molten wax, and has a low environmental impact when discarded. Further, in a usage mode in which the height of the molten brazing flow prevention body is higher than that of the combustion flame, the molten brazing flow prevention body also functions as a squirt, so even in use under windy conditions, the combustion flame Is hard to disappear and can be used safely outdoors. The candle of the present invention is biodegradable even when used as a single-use product, and therefore has a low environmental impact, and there is no need to clean and care for containers and squirts after use, and the handling is extremely simple. Moreover, the oil-resistant paper to be used has the advantage that it is excellent in biodegradability and has a small environmental load. Furthermore, by using a tracing paper having excellent transparency for the flame-retardant oil-resistant paper, if a function of allowing the light to be seen through the oil-resistant paper is given, a lantern is passed over the molten wax flow prevention body. Decorative effects tailored to the usage atmosphere can be obtained simply and easily, such as enjoying a soft and warm light.
