Description

The present invention relates to a combustion container for alcohol-based solid fuel.

Recently, a meal system called “Viking” or “Buffet”, which can eat as much as you like from a specified range, has gained popularity. In such a meal system, it is necessary to keep a large number of cooked dishes such as cooked dishes at a predetermined temperature for a certain period of time, and for this purpose, a dish warmer called “chafing” is often used.

Chaefing is a device configured to place a heat source under a dish or plate on which food is placed, and to keep the food warm by hot water or direct fire, but it is difficult to control the temperature with direct fire. For this reason, water (hot water) is often placed under the plate or plate, and the dish is often kept warm. When such chafing is used, conventionally, liquid fuel is put in a liquid fuel container having a combustion core, and the dish is kept at a predetermined temperature by burning the combustion core and boiling water.

However, when such liquid fuel is used, it is necessary to put a certain amount of liquid fuel in the liquid fuel combustion container. In that case, it is necessary to open the lid and replenish the fuel. When used a certain number of times, it is necessary to replace the combustion core in addition to the fuel.
Also, when transferring liquid fuel to a liquid fuel combustion container or carrying a container containing liquid fuel, liquid fuel is likely to spill, and there is a risk of fire if liquid fuel spills. . In addition, there is a large amount of smoke and soot generated from the flame, and there is a problem that a large amount of smoke is generated particularly during fire extinguishing. Furthermore, there is a problem that it is difficult to ignite when the combustion core is ignited.

On the other hand, it is also possible to keep the chafing warm using an alcohol-based solid fuel. When solid fuel is used, the solid fuel may be simply placed in a container and ignited with a lighter or the like before starting the heat insulation for cooking or the like. Moreover, since there is no need to replace the combustion core and there is no risk of fuel spilling, preparation before use is extremely simple. In addition, when liquid fuel is used, if liquid fuel is spilled, the spilled liquid fuel may catch fire and there is a risk of fire, but in the case of solid fuel, there is a risk of such fire. It has an excellent feature that there is no.
Therefore, recently, heat insulation of chafing using solid fuel instead of liquid fuel has been studied.

As a combustion container for alcohol-based solid fuel used for such an application, the support base is composed of only a container for storing solid fuel, or a container section for storing solid fuel and a support base section for supporting the container. Although the whole upper surface of the part is joined, these containers are heated to about 55 ° C. or less due to the combustion heat of the solid fuel when the cooking is kept warm. It takes time to reach the temperature. Therefore, there is a problem that it is difficult to hold and move the solid fuel combustion container by hand immediately after the heat preservation of the dish.

The present invention has been made in order to solve the above-described problems. An alcohol-based solid fuel combustion container that can be grasped and moved by hand even after the combustion of the solid fuel is completed. The purpose is to provide.

That is, the alcohol-based solid fuel combustion container according to the present invention includes a lid portion having an opening, a container portion that is open at the top and accommodates the alcohol-based solid fuel, and a support base portion that supports the container portion. An alcohol-based solid fuel combustion container provided, wherein the container part is located inside a region similar to the upper surface of the support table centered on a center point of the upper surface of the support table. The area of the region similar to the upper surface of the support table is 36% or less of the area of the upper surface of the support table.

The combustion container for alcohol-based solid fuel according to the present invention includes a support base part that supports the container part, and is located inside a region similar to the upper surface of the support base part with the center point of the upper surface of the support base part as the center. The area of the region similar to the upper surface of the support base is 36% or less of the area of the upper surface of the support base. The distance from the support part to the side is long, and heat is not easily transmitted. Therefore, even after the combustion of the alcohol-based solid fuel contained in the container portion is completed or during combustion, the temperature of the side surface of the support base portion is not so high, and it easily contacts the side surface of the support base portion by hand. It is possible to hold and carry a combustion container of alcohol-based solid fuel.
Note that similarity means that a plurality of figures are in a reduction or enlargement relationship, and in a polygon, the corresponding corners are equal in size and the corresponding side length ratio is equal.

In the alcohol-based solid fuel combustion container according to the present invention, it is preferable that the support portion is a single support portion, and the support portion is present in a portion including the center point of the upper surface of the support base portion.
In the alcohol-based solid fuel combustion container, since the support part is present in a portion including the center point of the upper surface of the support base part farthest from the side surface of the support base part, heat is not easily transmitted and the support part is accommodated in the container part. Even after the combustion of the alcohol-based solid fuel is completed or during combustion, the temperature of the side surface of the support base does not increase, and it can be easily brought into contact with the side of the support base by hand.

The combustion container for alcohol-based solid fuel according to the present invention is composed of one or more support parts, but three or more support parts are desirable to ensure the strength of the support part. Further, it is desirable that the three or more support portions exist in a rotationally symmetrical manner around the center point of the upper surface of the support base portion.
In the alcohol-based solid fuel combustion container according to the present invention, the container portion is supported by three or more support portions, and the three or more support portions are located inside an area of 36% or less of the area of the upper surface of the support base portion. Is present, the distance from the support part to the side surface is long, and heat is not easily transmitted. Therefore, even after the combustion of the alcohol-based solid fuel contained in the container portion is completed or during combustion, the temperature of the side surface of the support base portion does not increase, and it easily contacts the side surface of the support base portion by hand. Can be carried around.
In addition, since the three support portions exist in a rotationally symmetrical manner with respect to the center point of the upper surface, the container portion can be stably supported by the three support portions, is not easily damaged, and has excellent durability. It becomes a combustion container for alcohol-based solid fuel.

In the alcohol-based solid fuel combustion container of the present invention, the radius of the circle centering on the center point of the upper surface of the support base is 24 mm or less, and the radius of the upper surface of the support base is 40 to 60 mm. Is desirable.
This is because, when the radius of the upper surface of the support base is 40 to 60 mm, if the support is present inside a circle having a radius of 24 mm, the distance from the support to the side surface is long, and heat is not easily transmitted.

In the alcohol-based solid fuel combustion container of the present invention, the distance between the bottom surface of the container part and the top surface of the support base part in the vicinity of the support part is preferably 1 mm or more.
In this alcohol-based solid fuel combustion container, since the distance between the bottom surface of the container portion and the top surface of the support base in the vicinity of the support is 1 mm or more, heat is transferred from the container to the top surface of the support base. It is difficult and can be easily brought into contact with the side surface of the support base by hand, and the combustion container for alcohol-based solid fuel can be grasped and carried.

As for the distance of the bottom face of the said container part in the said support part vicinity, and the upper surface of the said support stand part, it is more desirable that it is 3-10 mm.
As the distance between the bottom surface of the container part and the upper surface of the support base part increases, the temperature of the support base part is less likely to rise, but if it is about 10 mm away, even immediately after the completion of the combustion of the alcohol-based solid fuel, It can be kept at a sufficiently low temperature. On the other hand, if the distance between the bottom surface of the container portion and the upper surface of the support base portion is too long, it is necessary to increase the height of the support portion, which makes processing difficult.
Incidentally, the vicinity of the support part means a part of the bottom surface of the container part and the support base part that is not affected by the formation of the support part as close as possible to the support part. The difference in position) is the distance between the bottom surface of the container portion and the top surface of the support base portion.

In the alcohol-based solid fuel combustion container of the present invention, it is preferable that the container part, the lid part, and the support base part are made of metal.
This is because if the container part, the lid part, and the support base part are made of metal, they can be easily molded into a predetermined shape, have excellent durability, and can be lightweight.

The alcohol-based solid fuel combustion container according to the present invention is preferably used for heat insulation of chafing in which food is placed in a predetermined container and the food is kept warm for a predetermined time.
Since the combustion container for alcohol-based solid fuel of the present invention is configured as described above, preparation before use is simple, ignition is easy, there is no fear of a fire, and combustion of alcohol-based solid fuel is performed. The container itself can also be easily carried before and after keeping the chafing warm. Therefore, the combustion container for alcohol-based solid fuel of the present invention is optimal for keeping warm the chafing.

The cylindrical container part 11 and the support base part 13 which supports the container part 11 with the three support parts 130 are provided, and the container part 11 can accommodate the alcohol-type solid fuel 14 in the inside. It is like that.

The support base part 13 has a cylindrical shape with a lid, and three support parts 130 for supporting the container part 11 are formed on the upper surface 13a. The support section 130 has a trapezoidal shape in a vertical cross section (a shape in which the upper part of the cone is cut to form a flat surface when viewed three-dimensionally), and the upper base of the trapezoid is welded to the container section 11. It is joined by joining means such as. The support base 13 may have a substantially trapezoidal vertical cross section in which the outer diameter slightly increases as going downward.

The three support portions 130 are present inside a circle centered on the center point P of the upper surface 13 a of the support base portion 13, and the area of the circle is 36% of the area of the upper surface 13 a of the support base portion 13. It is as follows. Below, the inside of the circle centering on the center point P of the upper surface 13a of the support base part 13 is also called the support part existence area A.
That is, three support portions are arranged inside a circle having an area of 36% or less of the area of the support base portion 13 around the center point P of the upper surface 13a of the support base portion 13, that is, inside the support portion existence region A. 130 exists.

Further, the three support portions 130 exist three times around the center point of the upper surface 13a of the support base portion 13 in plan view. That is, as shown in FIG. 1C, when a straight line is drawn between the center point P of the upper surface 13a in plan view and the centers of the two support portions 130, the angle θ formed by the two straight lines is measured. Three support portions 130 are arranged so that θ = approximately 120 °. However, the position of the support portion 130 does not need to be disposed at a strictly rotationally symmetric position. For example, when the angle θ is measured, a position of about ± 20 ° is allowed. Further, the position from the center point P need not be exactly the same, and may be shifted back and forth by about 20% of the radius.

Although the radius of the upper surface 13a of the support base part 13 is not specifically limited, It is desirable that it is 40-60 mm, and the circle (support part existing area | region) centering on the center point P of the upper surface 13a of the support base part 13 is preferable.

Table 1 shows the maximum temperature of the handle, the evaluation results for “portability”, and the evaluation results for “storability”.

As is apparent from the results shown in Table 1, in the alcohol-based solid fuel combustion container according to Examples 1 to 3, the maximum temperature on the side surface of the support base is 55 ° C. or less. Therefore, the alcohol-based solid fuel combustion container according to Examples 1 to 3 can be carried even immediately after the completion of the combustion of the alcohol-based solid fuel, and can be carried from the chafing fuel container mounting portion 25 to another place. The combustion vessel for alcohol-based solid fuel can be moved easily. As a result, it became clear that cleaning up of the chafing became easier.

On the other hand, in the alcohol-based solid fuel combustion container according to Comparative Examples 1 to 4, the maximum temperature on the side surface of the support base is much higher than 55 ° C. It was found that it was difficult to move the combustion vessel of the solid fuel, and it was difficult to clean up immediately after the chafing heat insulation was completed.

The alcohol-based solid fuel combustion container according to Comparative Example 5 is provided with a handle 71 for carrying it, so that it can be easily carried just after the combustion of the alcohol-based solid fuel is finished, but it is bulky and therefore has a storage property. For example, there is a risk that someone touches the handle 71 of the alcohol-based solid fuel combustion container 70 placed on the fuel container mounting portion 25 and the alcohol-based solid fuel combustion container 70 falls over. There is sex.

It may have a hanging part configured to be able to. Further, the lid portion may not be displaced when covered with the container portion, and the width thereof is larger than the diameter of the container portion, and a groove may be formed in the upper portion of the container portion.
Furthermore, the shape of the opening of the lid is not limited to a circle, and may be an ellipse or the like.

The container portion may be provided with a convex portion for fixing the alcohol-based solid fuel around the portion on which the alcohol-based solid fuel is placed at the bottom so that the alcohol-based solid fuel to be stored does not move.

Further, in the above embodiment, the alcohol-based solid fuel combustion container is composed of a main body container and a lid. However, the alcohol-based solid fuel combustion container is integrated with the lid and the container, and a predetermined upper portion is provided. An opening having a diameter may be formed.
In that case, an openable / closable door for accommodating the alcohol-based solid fuel needs to be provided on the side surface of the main body container.

The type of chafing to be kept warm is not particularly limited, and may be a hot water bath type or a type in which the plate is directly heated.
