Description

  The present invention mainly relates to an outdoor candle that is burned outdoors, and more particularly to an outdoor candle in which a combustion flame hardly disappears and a combustible agent does not droop when used.

The biggest problem when burning candles outdoors is the effect of wind. When burning indoors, it is only necessary to consider the effect of wind that is close to no wind, or wind blown from windows and doors, or air conditioning. You must consider being exposed to winds from various strengths and directions up to strong winds.
Therefore, in the conventional outdoor candle, in order to prevent the combustion flame from being extinguished by the wind, a candle having a larger combustion flame by increasing the combustion amount is used. For example, an outdoor candle having a burning core much thicker than that generally used, an outdoor candle in which a cloth impregnated with wax is wrapped around the outer peripheral surface of the combustion agent, and paper is wound around the outer peripheral surface of the combustion agent. A candle for outdoor use is known. In recent years, an outdoor candle has been proposed in which a combustible thin body such as paper, cloth or plastic is mounted on the outer peripheral surface of a candle body (Patent Document 1).
Furthermore, a combustion agent formed into a columnar shape, and a combustion cylinder in which a first sulfuric acid paper, a non-woven fabric, and a second sulfuric acid paper are sequentially laminated on the outer peripheral surface of the combustion agent from the combustion agent side are mounted. On the other hand, a candle has been proposed (Patent Document 2). On the other hand, the present applicant has integrated synthetic resin and plant fiber on the outer peripheral surface of the combustion main body composed of the combustion core portion attached to the outer peripheral surface of the combustor. An outdoor candle equipped with a thin composite (Patent Document 3) and an outdoor candle equipped with a thin body made of cellophane on the outer peripheral surface of a combustion agent are proposed (Patent Document 4).

  However, outdoor candles with a burning core that is considerably thicker than those commonly used in the center of conventional combustibles do not provide stable combustion under strong wind conditions, and in some cases combustion The flame may be extinguished. Also, outdoor candles wrapped with a cloth impregnated with wax in the combustion agent will extinguish the combustion flame when exposed to wind from various strengths and directions from light to strong winds during outdoor combustion. Although there is almost no, the combustible material melted during combustion drips along the side of the candle, solidifies at the bottom of the candle, or scatters around the candle foot due to strong wind, and remains as a residue after burning, so after the burning of the candle There has been a problem that much effort is required to remove the residue. Also, the combustion agent that melted during combustion, drooped along the side of the candle and solidified at the bottom of the candle is not only unsightly, but the combustible to be burned does not use for combustion and solidifies at the bottom of the candle There was a problem that the burning time was greatly shortened. In particular, in the production mode in which a large number of candles are burned at one time, the candle with the melted combustible agent finishes burning much earlier than the others, and there is no combustion flame only in that part, and the production effect by the flame Will be greatly reduced.

  Further, in the outdoor candle proposed in Patent Document 1, the molten wax rises and burns in the combustible thin body due to a capillary phenomenon. In other words, since the combustible thin body becomes the combustion core, it can be expected that the combustion flame becomes a large combustion flame with a large amount of combustion and prevents the combustion flame from being extinguished by the wind even under relatively strong wind conditions. In the case of a combustible thin body made of cloth or the like, the melted wax oozes out of the thin body, so that dripping cannot be prevented. Even when the film-like plastic is used for the flammable thin body, since the thin body becomes the combustion core, the film-like plastic is melted by the combustion flame blown by the wind. Therefore, the effect which prevents dripping is hardly expected. Moreover, the outdoor candle proposed in Patent Document 2 uses a laminated core in which the first sulfuric acid paper, the nonwoven fabric, and the second sulfuric acid paper are laminated in this order from the combustor side in order to prevent dripping. However, drooping still occurs (see Table 1). In addition, the combustion flame is small because the supply of the molten combustion agent to the non-woven fabric that becomes the combustion core is hindered by the oil-resistant sulfuric acid paper, and there is a possibility that it will disappear under wind. In the outdoor candle of Patent Document 3, depending on the degree of close contact between the combustion agent and the combustion cylinder, a part that is easy to burn is formed in the combustion cylinder, or the molten combustion agent leaks from the gap between the combustion agent and the combustion cylinder. The effect that prevents drooling may not be expected. The candle for outdoor use, in which the thin body made of cellophane is attached to the outer peripheral surface of the combustor proposed in Patent Document 4, although drooping drastically was reduced, cellophane has a drawback that it is easy to tear, and at the time of candle production, Alternatively, when the cellophane partially has a small rift during handling, the rift may be enlarged, or it may be heated by a combustion flame during use to expand the rip, and the wax may hang from the rift. Moreover, since cellophane has hygroscopicity and water absorption, quality variations due to storage conditions are inevitable.

  Accordingly, an object of the present invention is to provide an outdoor candle that has a large combustion flame when burned outdoors, is not easily extinguished by the wind, and is difficult for dripping molten combustible during combustion.

The inventor has reached the present invention as a result of intensive studies to achieve the above object. That is, according to the present invention, a thin oil-proof paper made of glassine paper having a thickness of 30 to 200 microns is attached to the outer peripheral surface of a combustion main body consisting of a combustion agent and a combustion core portion attached to the outer peripheral surface of the combustion agent. It is an outdoor candle characterized by being made.
The second invention is the outdoor candle according to claim 1, wherein the upper end of the combustion core portion is narrowed down.

Since the outdoor candle of the present invention is mounted with a thin oil-resistant paper made of glassine paper or tracing paper in close contact with the outer peripheral surface of the combustion main body made of the combustion core attached to the outer peripheral surface of the combustor. The amount of combustion is large, and even when used outdoors under strong wind conditions, the combustion flame is not easily extinguished by the wind. Further, a thin oil-resistant paper (hereinafter referred to as “thin oil-resistant paper” or “oil-resistant paper”) made of glassine paper or tracing paper used in the present invention is natural fiber (like cellophane used in Patent Document 4). Pulp) is used as a raw material, so that it does not permeate the molten combustion agent, and does not soften or melt like a synthetic resin thin body. In addition, thin oil-resistant paper made of glassine paper or tracing paper is stronger than ordinary paper and has excellent water resistance, so it is less susceptible to moisture than cellophane, is not easily torn, and is easy to handle. It becomes easy and uniform quality can be ensured.

  Furthermore, the thin oil-resistant paper attached to the outer peripheral surface of the combustor is in close contact with the combustion core attached to the outer peripheral surface of the combustor body, so that it is exposed to a combustion flame with a large combustion amount in the combustion process. Carbonize and burn. In other words, since the molten combustion agent does not rise in the thin oil-resistant paper due to capillary action, the combustion proceeds in a state where the thin oil-resistant paper tends to remain slightly more than the combustion agent, and carbonized at an appropriate place. Burn and burn. For this reason, a weir surrounded by a thin oil-resistant paper is formed on the upper part of the combustor main body, and the melted combustible liquid can be stored. In addition, there are various types and grades of oil-resistant paper, and by using an appropriate grade of oil-resistant paper, adhesion can be extremely improved when mounted on the combustor body. It is possible to prevent the molten combustion agent from leaking out from the gap with the oil resistant paper. In other words, the thin oil-resistant paper can sufficiently function as a weir to prevent the molten combustion agent from dripping, causing a phenomenon in which the combustion agent melted by the combustion flame blown by the wind droops along the side of the outdoor candle. In addition, the molten combustion agent hardly leaks from the gap between the combustion agent main body and the thin oil-resistant paper.

Moreover, in the outdoor candle of the present invention, since the thin oil-resistant paper is used, the molten combustion agent does not rise in the thin oil-resistant paper due to capillary action, and does not burn with the combustion core. . In addition, it becomes easy to attach the thin oil-proof paper to the outer peripheral surface of the combustion main body, and the thin oil-resistant paper does not float partially, showing outstanding stability as a product, and also about the drooping rate A very low and stable value will be shown.
As described above, the outdoor candle of the present invention is unsightly due to the burning agent melted during combustion dripping along the side of the outdoor candle, solidifying at the lower part of the outdoor candle, or being scattered around the feet of the outdoor candle by strong wind. Reduces dirt around the sheath and does not generate a large amount of residue after combustion, eliminating the need to remove the residue and drastically reducing the combustion time by allowing the combustible material to burn without dripping. Without having to do so, a sufficient combustion time can be secured. Since the burning time according to the predetermined burning time can be achieved, in the production mode in which a large number of outdoor candles are burned at a time, the burning time of all the outdoor candles can be made substantially the same, and only a part of the burning flame is produced. It is possible to produce an outstanding flame effect that is not found in the prior art. Further, since the combustion residue is extremely small, it is possible to greatly reduce the labor required for removing the residue of the combustion agent on which many outdoor candles hang down after the completion of combustion.

  In contrast to the limited use of cellophane as a packaging material, oil-resistant paper is used in many fields such as the food field and packaging materials, and there are various grades depending on the purpose, even though it is extremely versatile and inexpensive. is there. Furthermore, printing characteristics are good, and coloring, decoration, designs, letters, etc. can be freely added to the thin body, and the width of the design can be expanded, thereby providing an outdoor candle that is extremely rich in decoration. Furthermore, it is possible to easily and easily obtain a variety of decoration effects that match the usage atmosphere of outdoor events, festivals, religious events, and the like.

Next, an example of an outdoor candle according to the present invention will be described with reference to the drawings. FIG. 2 is a cross-sectional view of the outdoor candle of the present invention. The combustion core (1) is an outdoor candle mounted on the outer peripheral surface of the combustion agent (3), and the thin oil-resistant paper (4) is mounted in close contact with the outer peripheral surface of the combustion core (1). FIG. 3 is a cross-sectional view of another outdoor candle according to the present invention, in which the central combustion core (2) is disposed inside the combusting agent (3), and the combustion core portion (1) is disposed on the outer peripheral surface of the combusting agent (3). And a thin oil-resistant paper (4) is attached to the outer peripheral surface of the combustion core (1) in close contact with the outside candle. Further, FIG. 4 is a cross-sectional view of the outdoor candle of the present invention, in which the combustion core (1) is mounted on the outer peripheral surface of the combustion agent (3) and is narrowed down on the upper part of the combustion agent (3). This is an outdoor candle in which a thin oil-resistant paper (4) attached in close contact with the outer peripheral surface of the combustion core (1) also covers the bottom of the outdoor candle.
FIG. 5 is a perspective view of an outdoor candle according to the present invention, and shows a usage type in which the candle is floated upright in water as a floating type outdoor candle that floats in water. Further, FIG. 6 is a front view of the outdoor candle of the present invention, in which a desired color and pattern are added to the thin oil-proof paper, and designs, characters, etc. are added by known means such as writing, printing, and transfer. This is an outdoor candle.

  The combustion main body (5) used in the present invention includes a combustion agent (3) and at least a combustion core (1) mounted on the outer peripheral surface of the combustion agent. The combustion agent (3) is not particularly limited, For example, hydrocarbon compounds such as paraffin wax, synthetic waxes such as polyethylene wax, hardened oil made from various animal vegetable oils, higher fatty acids such as stearic acid, higher fatty acids such as wood wax and beeswax and higher alcohols Higher aliphatic alcohols such as esters and stearyl alcohol can be used, and further, waxes containing them can be used.

  The burning core (1) attached to the outer peripheral surface of the outdoor candle burning agent of the present invention (1) is made of paper, cloth, thread, string, etc., made of regenerated cellulosic fibers such as plant fibers or rayon. . A material having a capillary phenomenon that easily sucks up the melted combustion agent, and any known material can be used as a constituent material of the combustion core (1). The combustion core (1) is mounted and disposed on the entire outer peripheral surface or part of the combustion agent (3). The constituent material of the combustion core part (1) is a material that easily sucks up the molten wax, and the larger the proportion of the mounting form of the combustion core part (1) covering the outer peripheral surface of the combustion agent (3), the higher the sucked up molten wax. It becomes a candle for outdoor use with a large amount and a large amount of combustion. Further, a combustion main body used in the outdoor candle of the present invention, in which the combustion core portion (1) is mounted and disposed on the outer peripheral surface of a known candle in which the central combustion core (2) is disposed inside the combustion agent (3). (5) may be used. In this case, as the central combustion core (2) disposed inside the combustion agent (3), a known combustion core that is generally used can be used. Further, as the combustion main body (5), for example, a core is formed around the outer periphery of the combustion body such as an outdoor candle in which a cloth is wound around a central body mainly composed of conventional wax and the cloth is impregnated with wax. Known outdoor candles having the following may be used: The shape and size of the combustion main body (5) is not particularly limited. However, the thin oil-resistant paper (4) is mounted on the outer peripheral surface of the combustion main body (5) to exhibit the function of storing the molten combustion agent. For this, a simple shape without many irregularities is preferable. In addition to the rod-shaped combustion body that has been widely used in the past, cylindrical, prismatic, conical, inverted conical, frustoconical, and inverted frustoconical shapes can be attached to the combustion body (5). It is particularly desirable due to its ease.

  The thin oil-resistant paper (4) attached to the outer peripheral surface of the combustion body (5) has heat resistance and melt resistance in order to function as a weir to prevent the molten combustion agent from dripping. In addition, it is necessary to prevent the molten combustion agent from penetrating. The thin oil-resistant paper (4) does not melt or burn easily even when exposed to the burning flame of outdoor candles, but the burning flame tends to be small if it remains more than the combustion body (5) during the burning process. Therefore, it is necessary to burn gradually with the burning of the outdoor candle.

Note that the thin oil-resistant paper such as glassine paper or tracing paper referred to in this specification is paper that does not allow molten wax to permeate, ooze, or suck up.
Paper is generally made of cellulose fibers and has excellent heat resistance, but there are many fine gaps inside and contains air. As a result, the molten wax penetrates into the paper or oozes out to one side, and the molten wax cannot be stored, resulting in dripping.

  Accordingly, 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, glassine paper or tracing paper, which is called densification, reduces paper gaps by making a paper by striking a pulp raw material and smoothing the surface can be used as the oil-resistant paper of the present invention.

  Among them, glassine paper is widely used for food, is the cheapest among oil-resistant paper, has various grades such as thickness and oil resistance, is easy to use, and is a little rough as an outdoor candle. It is preferable because it is strong enough not to be damaged even if it is handled with care.

  As the thickness of the oil-resistant paper used in the outdoor candle of the present invention increases, it tends to remain in the course of combustion and becomes effective in preventing drooling, but tends to weaken the thermal power and fire power. Since the flame is consumed quickly by the flame, the effect of preventing the drooping without decreasing the heating power and the fire power tends to be reduced. Therefore, the thickness of the oil-resistant paper to be used is preferably selected and determined as appropriate in consideration of the combustion amount. Oil-resistant paper is usually commercially available with a thickness of 30 to 200 μm. A thin type oil-resistant paper is used for the combustion body (5) with a relatively small combustion amount, and a combustion body (5) with a relatively large combustion amount. Can be used by selecting a thick oil-resistant paper. It is also possible to give a performance equivalent to that of a thick type of oil-resistant paper by wrapping a thin type of oil-resistant paper twice or triple on the combustion main body (5) having a relatively large combustion amount.

  Moreover, as one form of the outdoor candle of the present invention, there is a type in which the combustion core (1) of the combustion main body (5) is waterproofed by wax impregnation or the like and the thin oil-proof paper (4) is attached. The outdoor candle configured as described above can be used as a floating type outdoor candle that is floated on water, and can be an excellent candle with drastically less drooping than the conventional candle.

  As a method for mounting the thin oil-resistant paper (4) on the combustion main body (5) of the outdoor candle of the present invention, the thin oil-resistant paper (4) is wound around the outer peripheral surface of the pre-formed combustion main body (5), The outer body of the combustion body (5) may be molded with a thin oil-resistant paper (4) using a known adhesive or adhesive means in advance. The combustion body (5) molded in this may be inserted and fixed. At this time, the thin oil-resistant paper (4) may be arranged in layers on the outer peripheral surface of the combustion main body (5) a plurality of times. Further, if necessary, the combustion main body (5) and the thin oil-proof paper (4) may be attached by adhesion or adhesion. At this time, the thin oil-resistant paper (4) may or may not cover the bottom of the combustion body (5). Further, for example, the combustion core part mounted on the outer peripheral surface of the combustion agent is impregnated with a part or all of the molten combustion agent, and then wrapped with a thin oil-resistant paper (4) and adhesively fixed with a cellophane adhesive tape. Alternatively, a thin oil-resistant paper (4) coated with an adhesive may be wound around and attached. Alternatively, a cellophane adhesive tape having a predetermined width may be wound and attached in a spiral shape with an overlap that does not cause wax leakage from the wound gap.

  In the outdoor candle of the present invention, it is desirable that the thin oil-resistant paper (4) is attached as closely as possible to the outer peripheral surface of the combustion body (5). There is a gap between the combustion main body (5) and the thin oil-resistant paper (4) when installed, or the thin oil-resistant paper is deformed after installation or when using an outdoor candle, and the combustion main body (5) and the thin oil-resistant paper are used. If a gap is formed between the thin oil-resistant paper (4), the thin oil-resistant paper (4) tends to burn before the combustion main body (5), and the function of preventing the molten combustion agent from dripping cannot be effectively exhibited. Absent.

  As shown in FIG. 5, a desired color or pattern may be added to the thin oil-proof paper (4) of the outdoor candle of the present invention, or a design, characters, or the like may be added by known means such as writing, printing, or transfer. it can. Furthermore, it is possible to add decorations, which makes it possible to easily and easily obtain a variety of decoration effects that match the usage atmosphere of outdoor events, festivals, religious events, and the like.

Next, the outdoor candle of the present invention will be described more specifically with reference to examples and comparative examples.
Five columnar-shaped combustion agents having a diameter of 32 mm and a length of 225 mm mainly composed of paraffin wax were prepared.

Comparative Example 1, Comparative Example 2 and Comparative Example 3: A commercially available bleached cloth (vertical 260 mm, horizontal 340 mm) was tightly wound around the outer peripheral surface of the combustion agent so as not to leave a gap, and the combustion core was formed on the combustion core. Five combustion bodies impregnated with paraffin wax were prepared. One of the combustion bodies was an outdoor candle and used as Comparative Example 1.
Also, compare a candle for outdoor use in which a biaxially stretched polypropylene film (OPP: vertical 225 mm, horizontal 210 mm) with a thickness of 50 μm is tightly wound around one outer peripheral surface of the combustion body and fixed with polypropylene tape without gaps. Example 2 was adopted.
Furthermore, a commercially available tracing paper having a thickness of 50 μm (vertical 112.5 mm, horizontal 210 mm) is tightly wound around one outer peripheral surface of the combustion agent so that there is no gap, and then a commercially available exposed cloth (vertical 260 mm, horizontal 340 mm) Wrap tightly so that there is no gap, impregnate with paraffin wax, and then bond a commercially available 50 μm thick tracing paper (vertical 112.5 mm, width 210 mm) with tight winding stick glue so that there is no gap A fixed outdoor candle was designated as Comparative Example 3.

Example 1 and Example 2: An outdoor candle in which a commercially available tracing paper (length: 225 mm, width: 210 mm) having a thickness of 50 μm is adhered and fixed to a single outer peripheral surface of a combustion main body with a tight stick glue so that there is no gap. Was taken as Example 1.
Furthermore, an outdoor candle in which a commercially available glassine paper having a thickness of 50 μm (vertical 225 mm, width 210 mm) was adhered and fixed to a single outer peripheral surface of the combustion main body with a tightly wound stick glue so as not to leave a gap was taken as Example 2.

  Using this Example 1 and Example 2, Comparative Example 1, Comparative Example 2 and Comparative Example 3, the height is 50 cm above the ground outdoors, and the example and the comparative example are alternately spaced at equal intervals of 50 cm. The fuel core was ignited using a gas torch, and the combustion characteristics and the state of sagging of the combustion agent in each of the examples and comparative examples were observed. In addition, the combustion time until the end of combustion and the weight of the combusting agent dripping until the end of combustion were measured. Furthermore, the ratio of the weight of the combusting agent that dipped until the end of combustion with respect to the weight of the candle before ignition was defined as the drooping rate. At that time, the wind conditions were such that the average wind speed was about 3 to 5 m / sec and the strong wind of about 8 to 10 m / sec was occasionally blown. The results are as shown in Tables 1 and 2.

  As shown in Table 1, in Comparative Example 1, drooping is severe even when there is no wind or light wind, the dripping rate is 53%, more than half of the combusting agent causes dripping, and the predetermined combustion time is halved. It is shown that. In Comparative Example 2, it is expected to prevent the OPP film from dripping when there is no wind or light wind, but it is wrapped around the outer peripheral surface of the combustion body by a combustion flame that falls to the leeward side under medium or strong wind conditions. The OPP film melted easily, and dripping occurred on the leeward side. The dripping rate was about 26%.

On the other hand, in Example 1 and Example 2, no drooling was observed when there was no wind or light wind, and drastically less drooping than Comparative Example 1 and Comparative Example 2 even under medium or strong wind conditions. . As shown in Table 1, the dripping rate was about 1% in Example 1 and about 2% in Example 2, which was extremely low.
That is, it was proved that the tracing paper and the glassine paper, which are oil-resistant papers, are extremely excellent as an anti-dripping effect as an outer skin material.

  Table 2 and FIG. 1 show the comparative transition of the average combustion amount for each combustion time interval between Comparative Example 3 and Example 1.

Comparative Example 3 reproduces the specifications and configuration of an outdoor candle shown in Patent Document 2, and includes 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. Table 2 and FIG. 1 show that the oil-resistant sulfuric acid paper inhibits the combustion by inhibiting the supply of the molten combustion agent to the combustion core, although it aims to prevent dripping by using. Yes.
In Comparative Example 3, it has been observed that the amount of combustion rapidly decreases as the combustion time elapses, and such a state has a high possibility of disappearing under wind and is extremely poor in practicality.

  On the other hand, Example 1 shows a state in which there is no significant change in the amount of combustion with the lapse of the combustion time, and a stable combustion state is maintained while dripping is almost prevented.

  The outdoor candle of the present invention has a large and stable combustion flame, and there is little dripping of the melted combustible agent and very little combustion residue. The labor required to remove the residue can be greatly reduced. In addition, oil-resistant paper has good printing characteristics and can freely add coloring, decoration, designs, letters, etc., can expand the width of the design, can provide outdoor candles that are extremely rich in decoration, outdoor events, Various decoration effects can be obtained easily and easily according to the usage atmosphere of festivals and religious events.
