【発明の属する技術分野】
本発明は、蚊取線香用断熱保温材および蚊取線香燃焼皿容器に関し、特に蚊取線香の燃焼時間が長くなるようにできる蚊取線香用断熱保温材および蚊取線香燃焼皿容器に関する。
【０００２】
【従来の技術】
従来、通常渦巻き状の形状をした蚊取線香を燃焼するに際しては、保持具で蚊取線香を水平或いは垂直に保持して燃焼させるやり方や、蚊取線香を薄い円形の皿状の形状をした蚊取線香燃焼皿容器内に直接入れて燃焼させるやり方がある。この蚊取線香燃焼皿容器では、安全のために蚊取線香用断熱保温材（以下「断熱保温材」又は「断熱保温シート」ということがある）が敷かれ、その上に蚊取線香を載置している。それに用いる断熱保温材の材料としてはアスベスト紙やガラスウール、ロックウールなどが知られている。
前記のアスベスト紙を用いるものとしては断面を波形に折り曲げた形状としたものがあるが、現在アスベストは安全上の問題で使用に適しないものであり、ガラスウールについてこのように加工をするとガラス繊維が折れるなどして適しない。また、そのアスベスト紙製の多孔薄板を波形に成形することも提案されているが、他の材料、例えばガラスウールについて多孔を設けるように加工することはコストの増大などで不利である。
【０００３】
このような事情で、現在断熱保温材としてはガラスウールから造られたマットが最も一般的に使用されている。
この種の蚊取線香燃焼皿容器に用いられるガラスウールから作られた平板状断熱保温材は、通常ガラスウールから平らでかつ多孔質のマット状体を形成するようにして成形して製造されているため、その表面は平滑なものとなっており、その平滑な表面上に蚊取線香を載せるように、その平板状断熱保温材を燃焼皿容器に固着されている。この断熱保温材の表面が前記したように平滑な面となっているのは、製造工程上の関係の他、表面が平滑な面のものは仕上がり面がきれいであるということで需要家に好まれる関係もあるのではないかと思われる。
【０００４】
【発明が解決しようとする課題】
蚊取線香燃焼皿容器は、安全のために通常は強度が大きくかつ不燃性であるということから、一般には金属で作られた皿形容器からなっており、またこれまでの蚊取線香燃焼皿容器（以下「燃焼皿容器」ともいう）では、燃焼皿容器に備える平板状断熱保温材は、その平滑な表面を蚊取線香の設置面として使用している。また、この燃焼皿容器を人の腰に吊り下げたり、家畜に付けるなどして移動できるように使用する場合があり、この場合には燃焼皿容器の蓋部分の内側にガラスウール製ネットを張り、その前記ネットと断熱保温材との間に蚊取線香を挟むような形態で使用されることがある。
このような燃焼皿容器で蚊取線香を燃焼させた場合、一般の静置型の燃焼容器で保持具で支持した状態で燃焼させる場合に比してその燃焼時間が短い、また使用中に立ち消えが起こり易いという欠点があった。
【０００５】
特に、ガラスウール製シートから構成された従来の断熱保温材の蚊取線香設置面では、ガラス繊維の毛足が約１ｃｍ以上と長いため、殆どのガラス繊維がシートの表面に沿って倒れており、蚊取線香を設置した際、設置する蚊取線香の面はシートの表面にピッタリと接触する状態となっていた。このため、蚊取線香の燃焼部がシートの表面に密着する状態となっているので、蚊取線香の燃焼時に生じるタールの付着量が多く、タール付着による蚊取線香の燃焼への影響があり、使用回数が多くなるとタール付着量が増していた。さらにタール付着量が多いため燃焼皿容器の洗浄を頻繁に行う必要があった。
本発明は、このような断熱保温材を使用する蚊取線香燃焼皿容器において、蚊取線香の燃焼時間がより安定して長くなり、また立ち消えすることがなく、タール付着量が少なくなるように改良された断熱保温材、或いはその断熱保温材を用いた蚊取線香燃焼皿容器を提供することを課題とするものである。
【０００６】
【課題を解決するための手段】
本発明の上記課題を解決するために、蚊取線香の燃焼状態を種々研究したところ、断熱保温材の表面が前記したように平滑であるために、蚊取線香の下面を断熱保温材の表面層が十分に覆うことになり、それにより断熱効果が大きくなって、蚊取線香の燃焼部における温度が高くなり過ぎて、燃焼速度が大きくなり、その結果燃焼時間が短くなるのではないかとの推論に立って、蚊取線香の下面に対する断熱保温材の表面層の接触面積を小さくするようにして実験したところ、燃焼時間が長くなるという好結果を得、それを基礎として本発明に到達した。
【０００７】
本発明は、下記の手段により上記した課題を解決した。
（１）表面上に蚊取線香を載置して燃焼させるための断熱保温材において、断熱保温材が無機繊維からなり、その表面が多数の起毛状になっている無機繊維により粗面化されていることを特徴とする蚊取線香用断熱保温材。
（２）前記無機繊維がガラスウールであり、その表面に起毛状になっているガラス繊維の起毛状の部分の長さが３〜８ｍｍであることを特徴とする前記（１）記載の蚊取線香用断熱保温材。
（３）前記断熱保温材の表面に直径が２〜３ｍｍのループ状にしたガラス繊維を５〜２０個／ｃｍ²の密度で存在させたことを特徴とする前記（１）又は（２）記載の蚊取線香用断熱保温材。
（４）前記（１）〜（３）のいずれかの蚊取線香用断熱保温材をその粗面化した表面が上面となるように配置させて容器の内底面に固着させたことを特徴とする蚊取線香燃焼皿容器。
【０００８】
【発明の実施の形態】
本発明において、断熱保温材を構成する材料としては、耐熱温度が高い、かつ不燃性であるという点から無機繊維を用いる。さらに、その性質としては、断熱材という点から、熱伝導性が低い材料が好ましい。この様な材料としては、具体的にはガラスウール、ロックウールなどが通気性、耐火性、強度や軽量の点から好ましい。特に、コスト面及び製造の容易性からガラスウールが最も好ましいものである。
蚊取線香燃焼皿容器内に敷く断熱保温シートは、前記のような無機繊維をフエルト状に形成してシートにしたものが好ましい。その際、通気性の関係から多孔質に作製したシートを用いることが好ましい。ガラスウールからなるシートの密度は、通気性とも関係するが、その密度の大きさはパンチングすることにより変えることができる。この断熱保温シートの製造においては、通常ガラスウールからなる不織布の製造に際して用いられている有機接着剤も支障がなければ使用することができる。
【０００９】
本発明において、断熱保温材の蚊取線香と接触する表面は、無機繊維を起毛状となっている構造とすることにより粗面化されるが、その粗面化された表面の形状としては、断熱保温材の表面における蚊取線香と接触する面の、断熱保温材の全表面に対する割合が小さくなるようにするほど良い。
形成する粗面化した表面としては、シートの表面から多数の無機繊維が起毛状とするような構造としたものがよい。
そのような構造を得るためには、例えばガラスウールのシートで、ガラス繊維の起毛状とした部分の長さが３〜８ｍｍとしたものを用いると、その表面層において多数のガラス繊維が起毛状で、例えば直立した構造のものとなり、接触面を少なくする粗面を形成することができる。ガラス繊維が起毛状とするような加工したものは、例えばガラスウールのシートの表面を毛羽立たせるように、表面加工することにより容易に得ることができる。
【００１０】
また、起毛状にするには、表面層に直径２〜３ｍｍのループ状のガラス繊維を多数存在させるようにしてもよく、そのループ状のガラス繊維の数は５〜２０個／ｃｍ²、好ましくは８〜１０個／ｃｍ²とするのがよい。或いは、このガラス繊維をシートの表面に直立させる手段とループ状のガラス繊維を形成させる手段の両者を併用してもよい。
その他、粗面化する手段として、ガラスウールのシートに短いガラス繊維を植毛するようにしてもよい。
【００１１】
前記断熱保温シートの厚みとしては、上に設置された蚊取線香が燃焼するときに発生する熱が皿容器に伝導するのを抑え、皿容器を乗せた床等が熱されることがないように、また吊り下げの形態で使用する場合には、人体にその熱が有害な程度に伝わるのを抑えられる程度のものであればよく、それが例えばガラスウール製である場合には２〜１０ｍｍの範囲が好ましく、３〜８ｍｍの範囲がさらに好ましい。
その厚みが薄いときには、容器底面への熱伝導量が大きくなるために、立ち消えが起こりやすい。
【００１２】
本発明の断熱保温材を使用する場合には、蚊取線香と接触する断熱保温材の面が粗面化されているために、蚊取線香裏面との接触面積が小さく抑えられるので、両者の間に空気が流通するなどの理由で、蚊取線香の燃焼部における熱が前記の断熱保温材との接触箇所に熱が溜まるということがないために、前記燃焼部の温度が必要以上に高くなることがないものとみられる。そのためか、この断熱保温材では、燃焼時間が短くなるという問題は起こらない。
そして、断熱保温材の面が粗面化されていることにより、蚊取線香が断熱保温材の面に密着しないので、前記したように燃焼部へ空気が十分に供給されることになり、前記燃焼部での燃焼が不完全燃焼となることがなく、そのために不完全燃焼の際に生じるタールの析出が少なくなる。
さらにまた、前記したようにシートの蚊取線香の燃焼部分との接触部分にタールがつきにくくなるので、単位時間当たりの燃焼速度は遅くなり、結果として蚊取線香は長時間もつことになり、断熱保温材シート上にタールの付く量が少ないので、断熱保温材シートの取替え回数や燃焼皿容器の洗浄回数を減らすことができる。
【００１３】
従来の燃焼皿容器においては、蚊取線香を燃焼皿容器に設置したときに、設置する蚊取線香の裏面全体が断熱保温材の表面に接触し、接触面積が大きくなっているため、断熱保温材の厚さが十分に厚いとか、あるいは断熱保温材の密度が高いなどにより断熱作用が良すぎることになると、蚊取線香の燃焼部の熱がそこに蓄積され、温度が高くなって蚊取線香の燃焼が良すぎて燃焼時間が短かくなっているものとみられる。また、断熱保温材の厚さが薄い場合や断熱作用が悪い時には蚊取線香の燃焼部の熱が多く外部に逃げるため、燃焼部の温度が低下して蚊取線香の立ち消えが起こり易いものとみられている。
【００１４】
本発明の断熱保温材及びそれを用いる蚊取線香燃焼皿容器を図面により説明すると、図１は、本発明の断熱保温材１を収容した蚊取線香燃焼皿容器（以下「燃焼皿容器」ともいう）２の皿部分５を断面図により示したものであり、断熱保温材１は、その表面に多数のループ状のガラス繊維３が形成されている。この断熱保温材１の上には渦巻き状の蚊取線香４が載置されている。
この燃焼皿容器２は、皿部分５と蓋部分６とからなっているが、図１には、蓋部分６を除いた残りの部分を示している。
皿部分５の内底面上に断熱保温材１が設けられ、図２にはその状態の斜視図を示す。また、図３は、本発明の蚊取線香燃焼皿容器全体の斜視図を示すものであるが、蓋部分６には外気と連絡している幾つかの孔７が開けられている。
【００１５】
また、蚊取線香は、従来から人が移動しながら使用したり、家畜に燃焼皿容器を付けて使用したりするために、例えば蚊取線香燃焼皿容器２を吊り下げできるようにしてもよく、そのためには前記容器の一端に吊り下げ用金具を設けることができる。
図４は、吊り下げ用燃焼皿容器５の蓋部分６の裏面（内側）を示す図である。蓋部分６の裏面には、ガラスウール製のネット８が蓋部分６には嵌められている。
【００１６】
先に説明した図３に示した本発明の蚊取線香燃焼皿容器について、その容器の蓋部分の裏側にガラスウール製のネットを設けることにより、図４の吊り下げ用蚊取線香燃焼皿容器とすることができる。この容器においては、蚊取線香を燃焼皿容器の蓋部分６の裏側のネット８と皿部分５（図４には示していない）に設けた断熱保温材シート１との間に蚊取線香を挟んだ時、断熱保温材シートの表面に設けた粗面化部分によって、蚊取線香と断熱保温材シートの間で接触面積を少なくすることができるので、蚊取線香の燃焼部分の温度が必要以上に高くならず、さらにまたシートの蚊取線香の燃焼部分との接触部分にタールがつくことも極めて少ないので、蚊取線香は長時間もつことになる。
【００１７】
本発明の断熱保温材シートは、その表面層に直径が２〜３ｍｍのループ状にしたガラス繊維を５〜２０個／ｃｍ²の密度で存在させたタイプのものを使用することが好ましい。この場合、ループ状にしたガラス繊維がシートの表面層に存在することで、断熱保温材シートの上に蚊取線香を載置した場合、又は蓋部分の網と皿部分に設けた断熱保温材シートとの間に蚊取線香を挟んだ場合のいずれにおいても、断熱保温材シートの表面層のループ状ガラス繊維によって蚊取線香と断熱保温材シートとの間に隙間ができるという特徴が発揮される。
また、吊り下げ用蚊取線香燃焼皿容器には、従来では厚みが５．５ｍｍや８．０ｍｍの断熱保温材シートを使用するのが通常であるが、本発明の断熱保温材シートを用いた場合にも厚み８．０ｍｍや５．５ｍｍ程度のいずれでも使用することができる。本発明の断熱保温材シートにおいては、目付け量はそのシートの厚さや多孔度により最適になるように自由に選択することができるが、８０〜９０ｋｇ／ｍ²の範囲のものが好ましい。
【００１８】

従来からある平板状で表面層が平滑である厚さ５．５ｍｍのガラスウールシートを比較品とした。
【００１９】
（蚊取線香燃焼皿容器）
直径１７１ｍｍで高さ２９ｍｍの鉄製皿容器の内底面に直径１６０ｍｍの前記した本発明の断熱保温材を設け、図３のように直径１３ｍｍの孔７を４９個設けた蓋部分６を乗せた。

【００２０】
蚊取線香の燃焼中は、試験室９内のドアを閉め、外気が低温でも、温室内の温度はかなり上昇するという温室効果を得て、さらに微風から無風条件をつくり、燃焼時間のバラツキを少なくした。

BACKGROUND OF THE INVENTION
The present invention relates to a heat insulating heat insulating material for a mosquito coil and an mosquito coil burning dish container, and more particularly to a heat insulating material for a mosquito coil and a mosquito coil burning dish container capable of extending the burning time of the mosquito coil.
[0002]
[Prior art]
Conventionally, when burning a mosquito coil with an ordinary spiral shape, the mosquito coil is burned by holding it horizontally or vertically with a holder, or the mosquito coil has a thin circular dish shape. There is a way to burn directly in a mosquito coil burning dish container. In this mosquito coil incense burning dish container, a heat insulating heat insulating material for mosquito coil (hereinafter sometimes referred to as "heat insulating heat insulating material" or "heat insulating heat insulating sheet") is laid for safety, and a mosquito coil is placed on it. It is location. As the material for the heat insulating and heat insulating material used therefor, asbestos paper, glass wool, rock wool and the like are known.
As the one using the asbestos paper, there is one having a cross-sectionally bent shape. However, asbestos is not suitable for use because of safety problems. Not suitable because it breaks. In addition, it has been proposed to form the perforated thin plate made of asbestos paper into a corrugated shape, but it is disadvantageous to process other materials, for example, glass wool so as to be porous, due to an increase in cost.
[0003]
Under such circumstances, a mat made of glass wool is most commonly used as a heat insulating and heat insulating material.
Flat heat insulating insulation made from glass wool used in this type of mosquito coil burning dish container is usually manufactured by molding so as to form a flat and porous mat-like body from glass wool. Therefore, the surface is smooth, and the flat heat insulating heat insulating material is fixed to the combustion dish container so that the mosquito coil is placed on the smooth surface. The surface of this heat insulation material is a smooth surface as described above, and it is preferred by consumers because of the fact that the surface is smooth in addition to the relationship in the manufacturing process. There seems to be a relationship.
[0004]
[Problems to be solved by the invention]
The mosquito coil incense burning dish container is usually made of a metal-made dish container because it is usually strong and non-combustible for safety. In the container (hereinafter, also referred to as “combustion dish container”), the flat heat insulation material provided in the combustion dish container uses the smooth surface as the installation surface of the mosquito coil. In addition, the burning dish container may be used so that it can be moved by being hung on a person's waist or attached to livestock. In this case, a glass wool net is stretched inside the lid part of the burning dish container. The mosquito coil may be used between the net and the heat insulating material.
When mosquito coils are burned in such a burning dish container, the burning time is shorter than in the case where they are burned in a state where they are supported by a holder in a general stationary type burning container, and they disappear during use. There was a drawback that it was easy to happen.
[0005]
In particular, on the mosquito coil incense installation surface of a conventional heat insulating and heat insulating material composed of glass wool sheets, the glass fiber has long hairs of about 1 cm or more, so most of the glass fibers are tilted along the surface of the sheet. When the mosquito coil was installed, the surface of the mosquito coil was in good contact with the surface of the sheet. For this reason, since the burning part of the mosquito coil is in close contact with the surface of the sheet, there is a large amount of tar that is generated when the mosquito coil is burned, and there is an effect on the burning of the mosquito coil. As the number of times of use increased, the amount of tar adhered increased. Furthermore, since the amount of tar adhered is large, it was necessary to frequently clean the combustion dish container.
In the mosquito coil incense burning dish container using such a heat insulating heat insulating material, the present invention makes the burning time of the mosquito coil incense more stable and longer, and does not disappear, so that the tar adhesion amount is reduced. It is an object of the present invention to provide an improved heat insulating heat insulating material or a mosquito coil incense burning dish container using the heat insulating heat insulating material.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems of the present invention, various investigations were made on the combustion state of the mosquito coil, and as described above, the surface of the heat insulating material is smooth. The layer will cover well, thereby increasing the heat insulation effect, the temperature in the burning part of the mosquito coil will become too high, the burning rate will increase, and as a result the burning time will be shortened Based on the reasoning, when the experiment was carried out by reducing the contact area of the surface layer of the heat insulating and heat insulating material to the lower surface of the mosquito coil, a good result that the burning time was lengthened was obtained, and the present invention was reached based on it. .
[0007]
The present invention has solved the above problems by the following means.
(1) In a heat insulating and heat insulating material for placing and burning a mosquito coil on the surface, the heat insulating and heat insulating material is made of inorganic fibers, and the surface is roughened by a plurality of brushed inorganic fibers. Insulated heat insulating material for mosquito coils.
(2) The mosquito trap according to (1), wherein the inorganic fiber is glass wool, and the length of the raised portion of the glass fiber raised on the surface thereof is 3 to 8 mm. Insulated thermal insulation for incense.
(3) The above (1) or (2), wherein glass fibers in the form of loops having a diameter of 2 to 3 mm are present on the surface of the heat insulation material at a density of 5 to 20 pieces / cm ^2. Heat insulation for mosquito coils.
(4) The heat insulating heat insulating material for mosquito coils in any one of the above (1) to (3) is disposed so that the roughened surface is an upper surface and fixed to the inner bottom surface of the container. Mosquito coil burning dish container.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, an inorganic fiber is used as a material constituting the heat insulating heat insulating material because it has a high heat resistance and is nonflammable. Furthermore, as its properties, a material having low thermal conductivity is preferable from the viewpoint of a heat insulating material. Specifically, glass wool, rock wool and the like are preferable from the viewpoints of air permeability, fire resistance, strength and light weight. In particular, glass wool is most preferable from the viewpoint of cost and ease of production.
The heat insulating and heat insulating sheet laid in the mosquito coil burning dish container is preferably a sheet formed by forming the above-described inorganic fibers into a felt shape. At that time, it is preferable to use a porous sheet from the viewpoint of air permeability. The density of the sheet made of glass wool is related to the air permeability, but the density can be changed by punching. In the production of the heat insulation and heat insulation sheet, an organic adhesive usually used in the production of a nonwoven fabric made of glass wool can be used as long as it does not interfere.
[0009]
In the present invention, the surface that comes into contact with the mosquito coil of the heat insulating and heat-insulating material is roughened by adopting a structure in which the inorganic fibers are raised, but as the shape of the roughened surface, It is better that the ratio of the surface in contact with the mosquito coil on the surface of the heat insulation material to the entire surface of the heat insulation material becomes smaller.
The roughened surface to be formed preferably has a structure in which a large number of inorganic fibers are raised from the surface of the sheet.
In order to obtain such a structure, for example, a glass wool sheet having a glass fiber raised portion with a length of 3 to 8 mm is used. Thus, for example, an upright structure is obtained, and a rough surface that reduces the contact surface can be formed. The processed fiber glass can be easily obtained by surface processing so that the surface of the glass wool sheet is fluffed, for example.
[0010]
In order to make it brushed, a large number of loop-shaped glass fibers having a diameter of 2 to 3 mm may be present on the surface layer, and the number of the loop-shaped glass fibers is preferably 5 to 20 / cm ² , preferably Is preferably 8 to 10 pieces / cm ² . Or you may use together both the means to make this glass fiber stand upright on the surface of a sheet | seat, and the means to form loop-shaped glass fiber.
In addition, as a means for roughening, short glass fibers may be planted on a glass wool sheet.
[0011]
As the thickness of the heat insulation and heat insulation sheet, the heat generated when the mosquito coil installed on the floor is burned is prevented from being conducted to the dish container so that the floor on which the dish container is placed is not heated. In addition, when used in a suspended form, it may be of a level that can prevent the heat from being transmitted to the human body to a harmful degree, and if it is made of, for example, glass wool, it is 2 to 10 mm. The range is preferable, and the range of 3 to 8 mm is more preferable.
When the thickness is small, the amount of heat conduction to the bottom surface of the container increases, so that it tends to disappear.
[0012]
When using the heat insulating heat insulating material of the present invention, since the surface of the heat insulating heat insulating material that comes into contact with the mosquito coil is roughened, the contact area with the back surface of the mosquito coil is reduced, so both Since the heat in the burning part of the mosquito coil is not accumulated in the contact area with the heat insulation material because the air circulates between them, the temperature of the burning part is higher than necessary. It will not be. For this reason, this heat insulating material does not cause a problem that the combustion time is shortened.
And, since the surface of the heat insulating heat insulating material is roughened, the mosquito coil is not in close contact with the surface of the heat insulating heat insulating material, so that air is sufficiently supplied to the combustion part as described above, Combustion in the combustion section does not become incomplete combustion, so that tar deposition generated during incomplete combustion is reduced.
Furthermore, as described above, tar does not easily stick to the contact portion of the sheet with the burning portion of the mosquito coil, so the burning rate per unit time is slow, and as a result, the mosquito coil will have a long time, Since the amount of tar attached to the heat insulation and heat insulating material sheet is small, the number of times of replacing the heat insulation heat insulating material sheet and the number of times of cleaning the combustion dish container can be reduced.
[0013]
In the conventional combustion dish container, when the mosquito coil is placed in the combustion dish container, the entire back surface of the mosquito coil is in contact with the surface of the heat insulation material and the contact area is large. If the thickness of the material is sufficiently thick, or if the heat insulation function is too good due to the high density of the heat insulation material, etc., the heat of the burning part of the mosquito coil will be accumulated there, the temperature will rise and the mosquito trap It seems that the burning of the incense stick is too good and the burning time is shortened. Also, when the heat insulation material is thin or when the heat insulation effect is poor, the heat of the burning part of the mosquito coil is likely to escape to the outside, so the temperature of the burning part is lowered and the mosquito coil is likely to disappear. It has been.
[0014]
The heat insulating heat insulating material of the present invention and the mosquito coil incense burning dish container using the same will be described with reference to the drawings. FIG. 1 is a mosquito coiled incense burning dish container (hereinafter referred to as “combustion dish container”) containing the heat insulating heat insulating material 1 of the present invention. 2) is a cross-sectional view of the dish portion 5 of FIG. 2, and the insulating heat insulating material 1 has a large number of loop-shaped glass fibers 3 formed on the surface thereof. A spiral mosquito coil 4 is placed on the heat insulating material 1.

The mosquito coil incense burning dish container of the present invention shown in FIG. 3 described above is provided with a net made of glass wool on the back side of the lid part of the container, whereby the hanging mosquito coil incense burning dish container in FIG. It can be. In this container, the mosquito coil is placed between the net 8 on the back side of the lid part 6 of the combustion dish container and the heat insulating heat insulating material sheet 1 provided on the dish part 5 (not shown in FIG. 4). Since the contact area between the mosquito coil and the thermal insulation sheet can be reduced by the roughened part provided on the surface of the thermal insulation sheet when sandwiched, the temperature of the burning part of the mosquito coil is necessary. Since it is not higher than that, and tar is hardly attached to the contact portion of the sheet with the burning portion of the mosquito coil, the mosquito coil will last for a long time.
[0017]
It is preferable to use the heat insulation heat insulating sheet of the present invention of a type in which glass fibers in the form of loops having a diameter of 2 to 3 mm are present at a density of 5 to 20 pieces / cm ^{2 on} the surface layer. In this case, when the mosquito coils are placed on the heat insulating and heat insulating sheet because the glass fiber in the form of a loop is present on the surface layer of the sheet, or the heat insulating and heat insulating material provided on the net and the dish part of the lid part In any case where a mosquito coil is placed between the sheet and the sheet, the loop-shaped glass fiber in the surface layer of the heat insulation sheet provides a gap between the mosquito coil and the insulation sheet. The
In addition, for a hanging mosquito coil incense burning dish container, it is usual to use a heat insulating heat insulating sheet having a thickness of 5.5 mm or 8.0 mm, but the heat insulating heat insulating sheet of the present invention was used. In this case, any thickness of about 8.0 mm or 5.5 mm can be used.
