Description

  The present invention relates to a candle, and more particularly, to a candle having a constant combustion and low flow wax even outdoors.

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 that can be used safely outdoors even when the wind blows, and can be used safely in the outdoors, a Japanese paper is wrapped around the candle body that has been hardened with a wax material around the candle core, and the surface of the Japanese paper is covered with the wax material Candle (Patent Document 1), a candle composed of a cylindrical wax placed inside a Japanese paper wound into a cylinder (Patent Document 2), a combusting agent, and at least the outer periphery of the combusting agent Known is a candle (Patent Document 3) in which a thin composite body in which a synthetic resin and a vegetable fiber are integrated is mounted on the outer peripheral surface of a combustion main body composed of a combustion core portion mounted on the surface. ing.

  However, many conventional candles for outdoor use have a thicker burning core than candles for indoor use, and the molten combustible material droops along the outer peripheral surface of the candle and solidifies at the lower part of the candle, or is used outdoors. There is a problem that it is scattered around the candlestick by the wind and remains as a residue after burning.

  In addition, even in the case of a candle in which the outer peripheral surface of the candle is wound with Japanese paper or the like, it is difficult for the combustion of the combustor to be burned uniformly over the entire outer periphery, and the liquefied combustor tends to flow down from a part of the outer periphery Become. For this reason, the amount of the combustible material used for actual combustion is reduced, and the conventional outdoor candle has a problem that the combustion time is shortened.

  The present invention has been made to cope with such a problem. Even in the case of an outdoor candle, it maintains a uniform combustion speed over the entire circumference, and the combustion agent can be used efficiently, thereby extending the combustion time. The purpose of the present invention is to provide a candle that can reduce the flow wax.

The candle of the present invention is a candle composed of a combustion agent formed in a columnar shape and a combustion cylinder fixed to the outer periphery of the combustion agent, and the combustion cylinder has at least sulfuric acid paper disposed on the combustion agent side. It is a laminated core.
In particular, the laminated core is characterized in that the first sulfuric acid paper, the nonwoven fabric, and the second sulfuric acid paper are laminated in this order from the combustion agent side.
Further, the first and second sulfuric acid papers laminated on the outer periphery of the combustion agent are sulfuric acid papers of the same type and thickness.
The candle of the present invention is characterized in that when the combustion cylinder burns, the upper surface of the liquefied combustion agent burns while being substantially constant with the combustion surface of the sulfuric acid paper disposed on the combustion agent side.

  Since the candle of the present invention is a laminated core in which at least sulfuric acid paper is arranged on the side of the combustion agent formed in a columnar shape, the first sulfuric acid paper, the nonwoven fabric, and the second sulfuric acid paper are particularly arranged from the combustion agent side. Since the combustion cylinders are sequentially stacked, the combustion cylinders burn at a uniform combustion rate. Therefore, the combustion agent can be used efficiently, so that the combustion time can be lengthened and the flow wax can be reduced.

It is sectional drawing of a candle. It is sectional drawing which shows the combustion state of a candle. It is a photograph which shows the burning state of a candle.

An example of the candle of the present invention is shown in FIG. FIG. 1 is a sectional view of a candle.
The candle has a laminated core composed of a burning agent 1 formed in a columnar shape, and a first sulfuric acid paper 2a, a nonwoven fabric 3, and a second sulfuric acid paper 2b laminated on the outer periphery of the burning agent 1. The main combustion core is the nonwoven fabric 3.

  As the material of the combustion agent 1, materials conventionally used as a combustion agent for candles, such as paraffin wax, Fissa tropish wax, natural gas wax, polyethylene wax, plant wax, beeswax, etc., may be used alone or in combination. Can be used. 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.

If the shape of the combustion agent 1 is cylindrical, it can be used. Examples of preferable cylindrical shapes include a perfect circle, an ellipse, and a deformed circle. Among these, a perfect circle is preferable because combustion proceeds uniformly over the entire outer periphery.
The combustion cylinder laminated | stacked on the outer periphery of the combustion agent 1 turns into a combustion core, without providing a combustion core in the combustion agent 1 inside.

As the size of the candle, it is preferable that the height of the candle is up to about 500 mm and the overall outer diameter is up to about 85 mm.
If the size of the candle is within this range, it can be burned for several hours without being broken during use as an outdoor candle for use in events or the like. In addition, advertisements and event names can be displayed clearly and clearly on the outer surface of the candle.

The laminated core serving as the combustion cylinder has at least sulfuric acid paper disposed on the side of the combustion agent, and the main combustion core is laminated on the outer periphery of the sulfuric acid paper. In addition, it is preferable to place sulfate paper on the outermost layer of the laminated core.
A preferred laminated core structure is a structure in which the first sulfate paper 2a, the nonwoven fabric 3, and the second sulfate paper 2b are laminated in this order.

  A laminated core serving as a combustion cylinder is formed by sequentially laminating the first sulfuric acid paper 2 a, the nonwoven fabric 3, and the second sulfuric acid paper 2 b on the outer peripheral surface of the combustion agent 1. The combustion cylinder composed of the first sulfuric acid paper 2a, the nonwoven fabric 3, and the second sulfuric acid paper 2b can be laminated by winding around the outer peripheral surface of the combustion agent 1 in order, or can be formed into a cylindrical shape in advance. The bodies can be overlapped and fixed to the outer peripheral surface of the combustion agent 1. Further, a combination of these may be used. As a method of winding, for example, it can be obtained by winding a tape-like nonwoven fabric or the like in a spiral. When wound in a spiral, the end portions in the width direction of the tape may be butted or overlapped. Or the width direction edge parts, such as a wide nonwoven fabric, can be faced | matched and piled up to a cylindrical body.

Sulfuric acid paper is one of the processed papers. The base paper made from pulp is passed through concentrated sulfuric acid to modify the surface fibers, and it is thin and water and oil resistant. Also called parchment paper or pseudo-parchment.
As a commercial product of sulfuric acid paper, Oji Special Paper Co., Ltd. trade name drape can be preferably used. Drip is a drip base paper treated with a sulfuric acid solution that turns the paper fibers into a tenacious, translucent gelatinous amyloid called amyloid, which binds the paper fibers together and plugs the paper pores. Therefore, it has the following characteristics.
Oil resistance: Due to the action of amyloid, the oil resistance is stronger than ordinary paper.
Water resistance: High wet strength and water resistance.
Aroma retention: Prevents ventilation with the outside air and keeps the aroma inside.
Strong strength: Due to the action of amyloid, it has higher tear strength and tensile strength than ordinary paper.
Peelability: Since the surface strength of the paper is strong and the fibers do not peel, there is weak peelability.
Translucency: With translucency, the appearance of products and printed materials can be expressed.
Examples of the drape having the above characteristics include drape F, drape W, drape WS, and art drape. Among these, drape F is preferable.

As the non-woven fabric, a non-woven fabric can be preferably used by using natural plant fibers such as cotton and hemp yarn and regenerated fibers such as rayon.
The order of lamination of the sulfuric acid paper and the nonwoven fabric is preferably the order of the first sulfuric acid paper, the nonwoven fabric, and the second sulfuric acid paper from the combustion agent side. By first laminating the first sulfuric acid paper on the combustion agent side, the liquefied combustion agent does not leak from the first sulfuric acid paper, and the upper surface of the combustion agent becomes substantially constant with the upper surface of the first sulfuric acid paper. .
In addition, it is preferable that the first and second sulfuric acid papers are the same type and thickness of sulfuric acid paper because combustion becomes uniform.

In addition to the non-woven fabric, a woven or knitted fabric using natural vegetable fibers such as cotton and hemp yarn and regenerated fibers such as rayon can be used as the main combustion core. When a woven fabric or a knitted fabric is used, it can be a seamless 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.
In addition to the non-woven fabric, woven fabric or knitted fabric, paper can be used as the main combustion core.
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.

  The combustion cylinder can be formed by winding a combustion core containing at least sulfuric acid paper as a laminated core around the outer periphery of the combustion agent 1. When wrapping, a paper adhesive such as a water paste mainly composed of polyvinyl alcohol or a water paste mainly composed of a vinyl acetate copolymer can be used. Alternatively, it can be fixed by impregnating wax.

The burning state of the candle shown in FIG. 1 will be described with reference to FIG. The burning of the candle of the present invention continues in the cycle of FIGS. 2 (a) to 2 (c). 2 (a) to 2 (c), 1a represents a combustion agent liquefied by the heat of the combustion core, and 4 represents a flame state.
By igniting the nonwoven fabric 3, as the flame 4 travels down the nonwoven fabric 3, the solid combustion agent (wax) 1 melts and becomes a liquefied combustion agent 1a (FIG. 2 (a)).
The nonwoven fabric 3 burns while sucking up the liquefied combustion agent 1a. The first sulfuric acid paper 2a around the liquefied combustion agent 1a is not combusted by being cooled by the liquefied combustion agent 1a (FIG. 2 (b)).
The non-woven fabric 3 sucks and burns the liquefied combustion agent 1a, and the first sulfuric acid paper 2a and the second sulfuric acid paper 2b exposed as the liquid level lowers burns (FIG. 2 (c)).
Combustion continues in the cycle shown in FIGS. 2A to 2C, so that the upper surface of the liquefied combustion agent 1a burns while being substantially constant with the combustion surface of the first sulfuric acid paper 2a.

The candle of the present invention can efficiently burn the combustion agent, so that the combustion time can be lengthened and the flow wax can be reduced.
For this reason, the candle of this invention can be utilized as a candle used outdoors, such as various events.
