［考案の目的］
（産業上の利用分野）
本考案は直火又は電磁調理器にて使用されて
局部加熱される可能性がある耐熱陶器製調理用容
器に関する。[Detailed Description of the Invention] [Purpose of the Invention] (Industrial Application Field) The present invention relates to a cooking container made of heat-resistant ceramic that can be used in an open flame or an electromagnetic cooker and may be locally heated.
（従来の技術）
この種の調理用容器としては例えば土鍋があ

度差が相当に大きくなるという事情がある。従つ

の熱膨脹率を抑えるようにした耐熱陶器製のもの
が多く供されている。(Prior Art) An example of this type of cooking container is an earthenware pot. Since this is used over an open flame, there is a considerable difference in temperature between the bottom part that comes in contact with the flame and the upper part of the peripheral wall that does not come into contact with it. Therefore, if products are manufactured using raw materials with a large coefficient of thermal expansion, cracks will occur during use over open flames, rendering them unusable.
It is necessary to keep the coefficient of thermal expansion as low as possible. Therefore, in recent years, many products made of heat-resistant ceramics have been provided in which the overall coefficient of thermal expansion is suppressed by blending petalite, which has a negative temperature coefficient, into the raw material.
ところが、このペタライトは融点が低いため、
これを原料中に多く含む生地の耐火度は低くな

め、土鍋２の施釉部３は底面部を除いて施される
ことが一般的であつた。 However, since this petalite has a low melting point,
Fabrics containing a large amount of this in their raw materials have low fire resistance. For this reason, conventional earthenware pots were fired as shown in FIG. 5 in order to prevent deformation during firing. That is, an annular kiln tool 1 made of refractory material and having a hole in the center is placed in a firing furnace, and an earthen pot 2 is supported by the kiln tool 1 as shown in the figure. In this firing method, if the bottom part of the earthenware pot 2 is glazed, the earthenware pot 2 will stick to the kiln tool 1 through the glaze, so the glaze part 3 of the earthenware pot 2 is generally applied except for the bottom part. It was hot.

しかしながら、土鍋２を上述の構造とすると、

う問題がある。(Problem to be solved by the invention) However, if the clay pot 2 has the above-mentioned structure,
When the earthenware pot 2 is placed on a table or the like, the bottom part that comes into contact with the table surface is not covered with glaze and is in a rough state, so there is a problem of damaging the table.

い。(Function) The protruding tabs formed on the outer bottom of the container body are covered with glaze and have a smooth surface, so even if the tabs come into contact with the table surface, there is no risk of damaging the table surface. do not have. Also, since the inner circumferential side of the hook is a non-glazed part and there is no glaze, it is only necessary to use the unglazed part to support the container body on the kiln tool when firing the dough, and the dough is transferred to the kiln tool through the glaze. There is no problem of sticking.

温度は1150℃〜1250℃が好ましい。(Example) An example in which the present invention is applied to an earthenware pot will be described below with reference to FIGS. 1 and 2. Earthen pot 11
The container body 12 is manufactured by molding a heat-resistant pottery material containing petalite into a predetermined shape, drying it, and then firing it. In this example,
Since the conventional kiln tool 1 shown in FIG. 5 is not used, firing conditions are selected so that the dough does not deform. In order to obtain such firing conditions, for example, the fire resistance of the dough can be increased by, for example, adopting roller machine molding for shaping the dough, lowering the firing temperature compared to conventional methods, or reducing the petalite component. There are ways to increase it. Note that the firing temperature is preferably 1150°C to 1250°C.

６表面から浮き上がつた形態となる。 In the container body 12 of the earthenware pot 11, a first hook 13 having an annular protrusion is formed in the outer peripheral area of the outer bottom surface, and a first hook 13 is formed in the inner area of the container body 12.
The second and third hammers 14, 1 are concentric with the hammer 13 of
5 is formed as a concentric protrusion. Here, the protrusion heights h 1 , h 2 , h 3 of each of the hooks 13 to 15 from the outer bottom surface of the container body 12 are set such that h 1 is the maximum and h 2 = h 3 (h 1 > h 2 = h 3 ). Therefore, when the clay pot 11 is placed, for example, on the table 16, the first hook 13 located at the outermost periphery comes into contact with the surface of the table 16, thereby receiving the container body 12, and holding the second and third hooks. Hama 14 and 15 are table 1
6 It becomes a shape that stands out from the surface.

を防止できるようにしている。 The earthenware pot 11 has a glazed portion 1 in which almost the entire area including the first hook 13 is coated with glaze and covers the first hook 13.
7 is formed, but each of the second and third hammers 1
4 and 15 are not glazed and serve as non-glazed portions 18. The glaze applied to almost the entire area of the container body 12 is of a type that causes penetration.
Even if moisture that has penetrated into the inside of the earthenware pot 11 evaporates and expands when the earthenware pot 11 is heated, the pressure can be released through minute gaps created by the penetration to prevent the glaze from exploding.

にて、焼成時に釉薬を介して容器本体１２が窯道
具１９に固着してしまうという虞は全くない。 According to the earthenware pot 11 having the above structure, when it is placed on a table, the first hook 13, which is glazed and smooth, comes into contact with the table surface, thereby ensuring that the table surface is not damaged. It can be prevented. Moreover, even if the first hook 13 is covered with glaze in this way, since the non-glazed portion 18 is formed in each of the second and third hooks 14 and 15 on the inner circumferential side, the fabric During firing, the container body 12 may be supported so that the unglazed portion 18 is in contact with the kiln tool 19, as shown in FIG. With this, there is no possibility that the container body 12 will stick to the kiln tool 19 through the glaze during firing.

とができる。 Incidentally, in the above embodiment, the double hammers 14 and 15 are formed on the inner peripheral side of the first hammer 13, and the non-glazed portion 18 is formed therein, but the present invention is not limited to this, and the second hammer 13 is not limited to this. As shown in FIG. 3, substantially the entire inner peripheral side of the hammer 20 may be made into a non-glazed portion 21. Also, the fourth
As shown in the figure, the bottom of the dough may be supported by a plurality of support refractories (kiln tools) 22 with sharpened tips.
can be reduced to its minimum size. Further, in the above embodiment, an example was shown in which the present invention was applied to an earthenware pot used over an open flame, but the present invention can be similarly applied to a cooking container for an electromagnetic cooker in which a conductive layer is formed on the bottom of the container.

きるという優れた効果を奏するものである。[Effects of the invention] As described above, according to the cooking container of the invention, the tabs that come into contact with the surface of the table, etc. are coated with glaze, so the table will not be damaged.
Moreover, since the inner periphery of the hook is formed with an unglazed part that comes in contact with the kiln tool to support the container body when the dough is fired, the dough is attached to the kiln tool through the glaze when the dough is fired. This has the excellent effect of stably supporting the container body while preventing it from sticking.
