Description

  The present invention relates to a paper-like combustion body that can be used as a combustion body such as a candle by infiltrating a wax into a base material made of flat paper or nonwoven fabric and solidifying the wax.

Generally, a candle has a structure in which a cotton thread or the like is used as a core material, and wax or paraffin is molded around the core material. And a configuration in which a thin body made of cellophane is mounted on the outer peripheral surface of a combustion main body made of a combustion core material mounted and arranged on the outer peripheral surface of the combustor.
Japanese Patent Application Laid-Open No. 2015-110663 discloses a configuration in which thin oil-resistant paper is mounted instead of the cellophane.
In the above configuration, the combustion core is made of paper, cloth, thread, string, etc. made of regenerated cellulosic fibers such as plant fibers or rayon, and a material having a capillary phenomenon that easily sucks up the molten combustion agent is used. A thin oil-proof paper is attached to the outside to function as a weir that prevents dripping of the molten combustion agent. It is necessary to gradually burn with the combustion of the gas, and it is difficult to select a material for the control.
Further, a wax paper in which a paper is impregnated with wax is also known, but it is not assumed to be used as a burning body such as a candle and is not configured as such.

JP 2001-348594 A JP2015-110893A

The problem to be solved by the present invention is that a base material such as paper is impregnated or coated with a wax that is dissolved by heating, and the wax is uniformly permeated between pulp fibers of the base material to solidify it to form a combustion body.
When the wax does not penetrate into the substrate and adheres only to the surface, the wax dissolved in heat cannot be accumulated in the substrate and is difficult to vaporize.
The tip of the combustor is ignited and the wax around the base material is redissolved and held between the fibers of the base material, and the wax is raised by the capillary action of the fibers and vaporized close to fire, which burns Can cause a flame.
Thus, an object of the present invention is to provide a paper-like combustor that can be burned sequentially from the top to the bottom by burning.

In order to achieve the above object, the present invention provides a first aspect of the present invention.
In a paper-like combustion body having a combustion part having wax that has solidified by substantially uniformly penetrating between fibers of a flat base material made of paper,
The base material of the burning part has a basis weight of 80 to 1200 g / m ² , a thickness of 0.15 to 3.0 mm, and a density of 0.2 to 1.2 g / m ³ ,
Wax impregnation of the base material, characterized in that the paper-like combustion body I 5% to 80% der the weight of the substrate has become self-sustaining.
In the invention of claim 2,
The density of the base material of the combustion part is 0.2 to 0.6 g / m ³ .
In the invention of claim 3,
The thickness of the base material of the combustion part is 0.3 to 1 mm.
In the invention of claim 4,
The wax has a melting point of 40 to 120 ° C., an oil content of 1% or less, and a penetration of 1 to 30 when the penetration is 25 ° C.
In the invention of claim 5,
In the center of the upper end of the combustion section, an ignition projecting piece narrower than the lateral width of the combustion section is formed.
In the invention of claim 6,
A symmetrical taper portion is formed in which the lateral width gradually increases downward from the projecting piece portion of the combustion portion, and a leg portion for being inserted into the support portion is provided below the combustion portion. To do.

The paper-like combustion body of the present invention is cooled in a state where the wax penetrates into the gaps of the pulp fibers of the paper by impregnating or coating the melted wax on a substrate such as paper having a low density and a certain thickness. And solidify to form a combustion section.
When a fire is applied to the leading edge of the paper in the combustion section, the wax around the fired area melts with heat.
The melted wax is retained between the paper fibers, and at the same time, it rises by capillary action between the paper fibers and is heated and vaporized by the heat of the flame to burn as a new flame. It becomes ashes.
In this way, the paper and wax can be burned with flames up to the bottom of the combustion section.

Embodiments of the present invention will be described below.
The paper-like combustion body 1 has a flat base material 2 and a combustion part 6 made of a wax 5 which is solidly permeated between the fibers of the base material 2 so as to penetrate.
The combustor 6 may be the entire area of the paper-like combustor 1 or only a part, for example, the upper side.

[Base material]
The base material 2 of the combustion section 6 is made of paper or non-woven fabric made of 100% pulp, and has a liquid-absorbing property of the dissolved wax 5 described later, and the wax 5 is held in the fibers of the base material 2. It has the function of solidifying and having the strength to be self-supporting without being bent, bent or deformed in a state where the wax 5 is solidified.
Further, since the base material 2 is flat and has a substantially uniform thickness, the wax 5 impregnated in the base material 2 is configured to penetrate substantially uniformly over the entire surface of the base material 2.

The base material 2 has a vertically long rectangular shape with a low density (see FIG. 1).
The base material 2 has a basis weight in the range of 80 to 1200 g / m ² , a thickness in the range of 0.15 to 3.0 mm, and a density of 0.2 to 1.2 g / m ³ . Ranges can be used.
Basis ^weight, in the range of ^{110g / m 2 ~700g / m 2} , can be carried out uniformly impregnation better wax.
When the basis weight is less than 110 g / m ² or the basis weight exceeds 700 g / m ² , it is preferable that the density is low, for example, about 0.2 to 0.6 g / cm ³ , because the wax is more easily penetrated. .
The thickness of the base material 2 is more preferably in the range of 0.3 to 1.0 mm out of the range of 0.15 to 3.0 mm for easy impregnation. If the density is in the range of 0.2 to 0.6 g / cm ³ as described above, it is preferable that the wax easily penetrates.
Moreover, the width of the base material 2 is not particularly limited, and is appropriately determined according to the intended use. However, when used as a candle, it is preferably 20 cm or less.

For the density of the base material 2, not easily bend when the the range of 0.2~1.2g / ^{m 3} was free standing, but further, 0.6 g / cm ³ or less workability wax tends to further penetrate good.
The tensile strength of the base material 2 was 2 to 30 kn / m in the vertical direction and 1 to 20 kn / m in the horizontal direction, and the Gurley stiffness was 30 to 200 mN in the vertical direction and 15 to 150 mN in the horizontal direction.

The Klem water absorption of the base material 2 was in the range of 5 to 250 mm in both the vertical and horizontal directions.
This is because the wax 5 dissolved by heating is infiltrated into the base material 2 and impregnated in the gaps between the fibers of the base material 2.

As a method for infiltrating the dissolved wax, a wax (storage tank) of a predetermined shape is filled with the heated and dissolved wax, and the paper is immersed in the wax liquid or moved through the liquid into the fiber of the paper. There are a dipping method and a soaking method in which the wax is infiltrated, or a method in which the wax is infiltrated between the fibers of the paper by coating the dissolved wax on the paper surface.
In the former, for example, the tip of the paper wound into a roll is passed through the liquid from one of the pans filled with the dissolved wax, and is fed out to the other while immersed in the liquid. By returning it, mass production is easy.

  In addition, the base material 2 is odorless when burned when there is no additive other than pulp. However, when a scent may be produced during combustion or when a fragrance is added, an appropriate additive is used. It may be mixed.

It is preferable that the base material 2 of the combustion part 6 has an end formed on a projecting piece 3 for ignition that is narrower than the lateral width of the base material 2 (FIGS. 2, 3 and the like).
When the width of the base material 2 is narrow, it is not necessary to provide it. However, when the width is wide, it is easy to ignite by providing at least a projecting piece portion 3 having a narrow tip to facilitate ignition. It is convenient.
It is preferable that the width of the base material 2 of the combustion part 6 is the same as the bottom of one flame.

Although the shape of the projecting piece 3 is not particularly limited, by making it a mountain shape, the ignited fire can be spread evenly without being biased from the projecting piece 3 to the entire width of the main body portion 2A of the base member 2.
Therefore, when the width of the base material 2 is wide, it is preferable that the projecting piece 3 is arranged at the center of the tip of the base material 2.

[wax]
The wax 5 is preferably paraffin wax, but other waxes may be used.
In the present invention, the wax 5 has a melting point of 40 to 120 degrees Celsius, 96 to 287 degrees Fahrenheit, an oil content of 1% or less (mass%), and a penetration of 1 to 30 when the penetration is 25 ° C. be able to.
As the wax 5, a wax that does not contain a release agent such as a wax used for a candle is used.

The amount of the wax 5 impregnated into the base material 2 was 5 to 80 parts by weight with respect to 100 parts by weight of the base material in terms of solid content.
FIG. 8 shows a reference diagram in which the base material 2 is impregnated with the wax 5.
In the illustrated example, the case where a wax layer is formed on the front and back surfaces of the base material 2 is illustrated. However, the wax layer may not be formed on one or both of the front and back surfaces, and at least the gaps between the fibers of the base material 2 are impregnated. If you do.
The amount of the wax 5 impregnated with respect to the base material 2 is preferably in the range of about 10% to 70% because the flame is better.

In this example, the base material 2 was a perfume test paper (sold by Daimon Paper Co., Ltd.) with a length of 6 mm wide × 150 mm long.
The measured value of this base material 2 is as follows.
Basis weight 304.6g / m ²

The measured values of this wax 5 are as follows.
Melting point 53 ° C
Oil content 0.3
Penetration 15 (at 25 ° C)
The wax impregnation amount of the wax 5 with respect to the substrate 2 was 30% by weight.

As shown in FIG. 2, the paper-like combustion body 1 according to the first embodiment has a combustion portion 6 on the entire surface, and the base material 2 forms a narrowest protrusion 3 at the center of the upper end. A symmetrically tapered portion 8 is formed so as to gradually widen downward from 3 downward.
In addition, the lower part is the leg part 4 and may remain wide, but the support part 9 (the sponge part in the case of a cake, and the paper-like combustion body 1 such as ash in the case of an incense holder) is supported. It is preferable to make it narrow so that it can be easily inserted, or to have a tapered shape that gradually narrows downward.
When the paper-like combustion body 1 is used as a candle, the leg portion 4 is inserted into the support portion 9 or sandwiched by the holding member 7 so as to stand upright, and the upper end protrusion 3 is ignited with fire. The combustion part 6 can be burned by generating a flame.

In each of the above-described embodiments, the entire surface of the paper-like combustion body 1 is the combustion section 6. However, the lower part of the paper-like combustion body 1 is the base material 2 alone, or at least the surface of the base material 2 is provided with a flame retardant layer or a non-combustion layer. The combustion section 6 may be adhered or locked to a coating member or a separate holding member 7 (see FIGS. 6 and 7).
The holding member 7 is preferably made of a material that is less flammable than the paper-like combustion body 1.
The holding member 7 in FIG. 6 has a rod-like member, and the holding member 7 in FIG. 7 has a clip-like upper portion, but other known members can be used.

Moreover, the number of the combustion part 6 does not need to be one, and it is good also as a shape which arrange | positions two or more in parallel at appropriate intervals, and is connected to the leg part 4 integrally by the lower part (refer FIG. 5).
