Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, since the fire starter of Patent Document 1 has a structure in which wood chips and rice bran are buried in wax, there is a problem that it is difficult to ignite, especially with a small ignition source such as a match or a lighter.

Means for Solving the Problems

[0005] Hereinafter, each aspect of the fire starter for solving the above problems will be described. [Aspect 1] A fire starter characterized in that a plurality of wood pieces are arranged in a state of protruding from at least a part of the surface portion of a mixed material in which wax and wood powder are mixed.

[0006] According to the above configuration, multiple wood chips protrude from the surface of the mixed material, making them easily ignitable. Therefore, the wood chips can be easily ignited with a small flame such as a match or lighter. Once the wood chips are ignited, the flame from the wood chips spreads to the mixed material. As a result, the mixed material burns due to the flame from the wood chips, but because it is a mixture of wax and wood powder, the burning rate is slower compared to a mixture without wood powder. Therefore, the burning time of the mixed material can be extended. Thus, both ignition and burning duration can be achieved.

[0007] [Aspect 2] The ignition material according to [Aspect 1], characterized in that the wood chips are arranged in a part of the surface portion of the mixed material, and the density of the wood powder in the mixed material is greater in the part of the mixed material that is farther from the wood chips than in the part of the mixed material that is close to the wood chips.

[0008] According to the above configuration, the parts of the mixture closer to the wood chips burn faster than the parts further away from the wood chips, making it easier for the fire from the wood chips to spread. On the other hand, the parts of the mixture further away from the wood chips burn slower than the parts closer to the wood chips, resulting in a longer burning time for the mixture. Therefore, it is possible to make it easier for the fire from the wood chips to spread to the mixture while also extending the burning time of the mixture.

[0009] [Aspect 3] The ignition material according to [Aspect 1] or [Aspect 2], characterized in that the thickness of the wood chip is 10 micrometers or more and 1000 micrometers or less. According to the above configuration, since the thickness of the wood chips is 10 micrometers or more and 1000 micrometers or less, the ignition properties of the wood chips can be further improved. [Effects of the Invention]

[0010] This invention has the effect of achieving both ignition and sustained combustion. [Brief explanation of the drawing]

[0011] [Figure 1] This is a perspective view of an ignition material in one embodiment. [Figure 2] Figure 1 is a perspective view from the opposite side. [Figure 3] This is a cross-sectional view of Figure 2. [Figure 4] This is a schematic cross-sectional diagram showing one of the manufacturing processes for ignition materials. [Figure 5] This is a schematic cross-sectional diagram showing one of the manufacturing processes for ignition materials. [Figure 6] This is a perspective view of the ignition material in the modified example. [Modes for carrying out the invention]

[0012] One embodiment will be described below with reference to the drawings. <Ignition material 11> As shown in Figures 1 to 3, the ignition material 11 comprises a mixed material 12 as the main body, which is roughly frustoconical in shape and resembles a canelé, a type of baked confectionery, and a plurality of wooden pieces 13 arranged on a part of the surface of the mixed material 12.

[0013] The mixed material 12 has an outer diameter that gradually decreases from the first end 14 to the second end 15 in the axial direction. Multiple first grooves 16 are formed on the circumferential surface of the mixed material 12, extending linearly from the first end 14 to the second end 15 at equal intervals in the circumferential direction. A substantially circular recess 17 is formed in the center of the end face on the second end 15 side of the mixed material 12. The mixed material 12 is a mixture of wax 18 and wood powder 19. The main component of the wax 18 is, for example, paraffin.

[0014] The average particle size of the wood powder 19 is preferably 0.1 micrometers or more and 1000 micrometers or less. If the average particle size of the wood powder 19 exceeds 1000 micrometers, the effect of suppressing the combustion rate of the mixed material 12 may become too high. On the other hand, if the average particle size of the wood powder 19 is less than 0.1 micrometers, the effect of suppressing the combustion rate of the mixed material 12 may become too low.

[0015] The plurality of wood pieces 13 are arranged over the entire end face on the first end portion 14 side, which is a part of the surface portion in the admixture 12. That is, the plurality of wood pieces 13 are attached to the wax 18 constituting the admixture 12 in a state of protruding from the end face on the first end portion 14 side in the admixture 12. The thickness of the wood pieces 13 is preferably 10 micrometers or more and 1000 micrometers or less. When the thickness of the wood pieces 13 exceeds 1000 micrometers, the flammability of the wood pieces 13 may decrease. On the other hand, when the thickness of the wood pieces 13 is less than 10 micrometers, it may be difficult to obtain the wood pieces 13.

[0016] The length of the wood pieces 13 is preferably 1 millimeter or more and 15 millimeters or less. When the length of the wood pieces 13 exceeds 15 millimeters, the protruding amount of the wood pieces 13 from the end face on the first end portion 14 side in the admixture 12 may be too large, and the design property of the ignition material 11 may decrease. On the other hand, when the length of the wood pieces 13 is less than 1 millimeter, the protruding amount of the wood pieces 13 from the end face on the first end portion 14 side in the admixture 12 may be too small, and the flammability of the wood pieces 13 may decrease.

[0017] As shown in FIG. 3, the density of the wood powder 19 in the admixture 12 is greater in the portion farther from the wood pieces 13 in the admixture 12 than in the portion closer to the wood pieces 13 in the admixture 12. That is, the density of the wood powder 19 in the admixture 12 increases as it moves away from the wood pieces 13. That is, the density of the wood powder 19 in the admixture 12 gradually increases from the first end portion 14 to the second end portion 15 in the admixture 12.

[0018] <Manufacturing method of the ignition material 11> When manufacturing the ignition material 11, first, a predetermined amount of wood powder 19 is added to the wax 18 in a molten state by heating and stirred. At this time, the mixture of the wax 18 and the wood pieces 13 gradually changes from brown to black as the heating time elapses. Therefore, by adjusting the heating time of the mixture of the wax 18 and the wood pieces 13, the color tone of the mixture is adjusted to a desired color tone.

[0019] Subsequently, as shown in FIG. 4, the molten mixture is poured into a mold 20 of a predetermined shape. At this time, before the wax 18 in the mixture poured into the mold 20 cools and solidifies, the mold 20 is gently tapped. As a result, the air in the mixture within the mold 20 is discharged, and the wood powder 19 in the mixture settles.

[0020] Then, as shown in FIG. 5, the density of the wood powder 19 in the mixture within the mold 20 increases toward the bottom. Subsequently, a plurality of wood pieces 13 are attached over the entire supernatant portion 21 at the upper end of the mixture within the mold 20. At this time, a part of the plurality of wood pieces 13 protrudes above the supernatant portion 21, and the wax 18 penetrates into the plurality of wood pieces 13. After the wax 18 in the mixture has sufficiently cooled and solidified, the mixture with the plurality of wood pieces 13 attached is taken out of the mold 20, thereby obtaining the ignition material 11.

[0021] <Actions of the Embodiment> For example, when making a campfire outdoors during camping or the like, first, firewood is stacked on a campfire stand installed on the ground. Subsequently, the ignition material 11 is arranged under the firewood stacked on the campfire stand such that the wood piece 13 part is upward or horizontal. Subsequently, the plurality of wood pieces 13 in the ignition material 11 are ignited with a match, lighter, or the like. At this time, since the plurality of wood pieces 13 protrude from the surface portion of the mixing material 12 in the ignition material 11, even a small fire source such as a match or lighter can easily catch fire.

[0022] When the plurality of wood pieces 13 catch fire, the fire of the plurality of wood pieces 13 spreads to the mixing material 12. As a result, the mixing material 12 burns due to the fire from the plurality of wood pieces 13. However, since the wax 18 and the wood powder 19 are mixed, the burning rate is slower than when the wood powder 19 is not mixed. Therefore, the burning time of the mixing material 12 becomes longer.

[0023] Thus, in the ignition material 11, ignition is ensured by multiple wood chips 13, and combustion persistence is ensured by the mixed material 12. Therefore, by using the ignition material 11, fuel such as firewood can be ignited easily and efficiently.

[0024] <Effects of the Embodiment> According to the embodiments described in detail above, the following effects are achieved. (1) The ignition material 11 is configured such that a plurality of wood pieces 13 are arranged on at least a portion of the surface of a mixed material 12 which is a mixture of wax 18 and wood powder 19, with the pieces protruding from it.

[0025] According to the above configuration, multiple wood chips 13 protrude from the surface of the mixed material 12, making the wood chips 13 easily ignitable. Therefore, the wood chips 13 can be easily ignited with a small flame such as a match or lighter. When the wood chips 13 are ignited, the flame from the wood chips 13 spreads to the mixed material 12. As a result, the mixed material 12 burns due to the flame from the wood chips 13, but because it is composed of a mixture of wax 18 and wood powder 19, the burning rate is slower compared to when the wood powder 19 is not mixed in. Therefore, the burning time of the mixed material 12 can be extended. Thus, the ignition material 11 can achieve both ignition and sustained burning.

[0026] (2) In the ignition material 11, the wood chips 13 are arranged on a portion of the surface of the mixed material 12. The density of the wood powder 19 in the mixed material 12 is higher in the parts of the mixed material 12 that are further away from the wood chips 13 than in the parts of the mixed material 12 that are closer to the wood chips 13.

[0027] According to the above configuration, the portion of the mixed material 12 closer to the wood chips 13 burns faster than the portion of the mixed material 12 further away from the wood chips 13, making it easier for the fire from the wood chips 13 to spread. On the other hand, the portion of the mixed material 12 further away from the wood chips 13 burns slower than the portion of the mixed material 12 closer to the wood chips 13, resulting in a longer burning time for the mixed material 12. Therefore, it is possible to make it easier for the fire from the wood chips 13 to spread to the mixed material 12 while also extending the burning time of the mixed material 12.

[0028] (3) In the ignition material 11, the thickness of the wood chips 13 is 10 micrometers or more and 1000 micrometers or less. According to the above configuration, since the thickness of the wood chip 13 is 10 micrometers or more and 1000 micrometers or less, the ignition properties of the wood chip 13 can be further improved.

[0029] (4) The ignition material 11 is composed mostly of wax 18 on the surface of the mixed material 12, except for the end face on the side of the first end 14. According to the above configuration, the waterproofing of the portion of the surface of the mixed material 12 other than the end face on the first end 14 side can be ensured by the wax 18.

[0030] (5) The ignition material 11 is composed of wax 18 and wood. According to the above configuration, stickiness and odor of the ignition material 11 can be suppressed. <Example of changes> The above embodiment can be implemented with the following modifications. Furthermore, the above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0031] As shown in Figure 6, the mixed material 12 in the ignition material 11 may be in the shape of a rectangular plate resembling a chocolate bar, with a grid-like second groove 22 on one side. In this case, multiple pieces of wood 13 are attached to the side of the mixed material 12 opposite to the side with the second groove 22. This allows the ignition material 11 to be easily divided along the second groove 22, thereby improving the usability of the ignition material 11.

[0032] The mixed material 12 in the ignition material 11 may have its shape changed as desired. Multiple pieces of wood 13 may be placed on a portion of the end face on the first end 14 side, which is part of the surface portion of the mixed material 12.

[0033] • Multiple pieces of wood 13 may be arranged so that they protrude across the entire surface of the mixed material 12. The thickness of the wood chip 13 does not necessarily have to be between 10 micrometers and 1000 micrometers.

[0034] The density of the wood powder 19 in the mixed material 12 does not necessarily have to be higher in the parts of the mixed material 12 that are farther from the wood chips 13 than in the parts of the mixed material 12 that are close to the wood chips 13. [Explanation of symbols]
