成る鍋製品に関する。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a pot product made of aluminum or an alloy thereof and used for pots, frying pans, inner containers of electric kettles, etc.
（従来の技術）
一般にアルミニウム又はその合金から成る鍋製
品は、鍋本体の内外両面に硫酸又はシユウ酸法に
より陽極酸化被膜を設けて形成されている。(Prior Art) Generally, pot products made of aluminum or its alloys are formed by providing an anodic oxide coating on both the inner and outer surfaces of the pot body using a sulfuric acid or oxalic acid method.

とがあつたのである。(Problems to be Solved by the Invention) By the way, since the conventional pot product simply forms an anodized film on both the inner and outer surfaces of the pot body, the inner and outer surfaces of the pot body are each of the same color. In other words, when the pot body is anodized using the sulfuric acid method, a single transparent white coating is formed on both the inner and outer surfaces of the pot body, and when the pot body is anodized using the oxalic acid method, both the inner and outer surfaces of the pot body are anodized. Therefore, regardless of whether the sulfuric acid method or the oxalic acid method is used, only a single color coating is formed on both the inner and outer surfaces of the pot body. First, they lacked a good design and appearance, and the pot products were sometimes scorched on the inner surface of the main body during cooking.

て、製品が非常に高価となつたのである。 In addition, as a means to prevent the pan products from burning, conventionally, the inner surface of the pan body has been treated with a resin called Teflon treatment, but when applying this resin treatment, the production cost is high. , products became very expensive.

ことにある。 The present invention was devised in view of the above problems, and its purpose is to prevent the pan body from burning at a low production cost, and to apply the same anodizing treatment to both the inside and outside of the pan body. Nevertheless, it is an object of the present invention to provide a pot product made of aluminum or an alloy thereof, which can be colored differently on both the inner and outer surfaces of the main body to enhance the designed appearance.

ある。(Means for Solving the Problems) The pot product of the present invention is constructed as shown in FIGS. 1 and 2, and the inner surface of the pot body 1 made of aluminum or its alloy is processed by sandblasting or other processing means. At the same time as forming a rough surface 2, the main body 1 is treated by a naturally coloring anodic oxidation method using an organic acid bath to form a naturally colored coating 3 on both the inner and outer surfaces of the main body 1. It is characterized by having different colors.

的外観が高められるのである。(Function) Therefore, on the inner surface of the pot body 1, there is a rough surface 2,
In other words, when viewed macroscopically, an uneven surface is formed, and a naturally colored film 3 is formed on this rough surface 2. Therefore, when cooking is performed on the inner surface of the main body 1, the food to be cooked is Since the food comes into point contact with the rough surface 2 through the naturally colored coating 3 without coming into close contact with the surface, cooking food is prevented from burning on the inner surface of the main body 1. Since the roughened surface 2 is formed on the inner surface of the main body 1, and the roughened surface 2 is not formed on the outer surface and is flush, the reflectance of the inner and outer surfaces of the main body 1 is different. It is,
Therefore, when the main body 1 is treated by a naturally coloring anodic oxidation method to form a naturally colored coating 3 on both the inner and outer surfaces of the main body 1, the colors appearing from the inner and outer surfaces of the main body 1 are different. The different coloring on both sides enhances the aesthetic appearance of the pot product.

is formed, and the reflectance of the inner and outer surfaces of the main body 1 is different, so that the color of the colored coating 3 exposed to the outside from both the inner and outer surfaces of the main body 1 appears to be different. For example, in the case of the above-mentioned specific example, that is, when forming the colored film 3 of an amber color on both the inner and outer surfaces of the main body 1, a bright amber color is applied to the outer surface of the main body 1, and a bright amber color is applied to the rough surface 2 of the main body 1. Since the reflectance is lower than that of the outer surface of the main body 1, a dark amber color close to gray is formed, and the difference in color of the colored coating 3 formed on both the inner and outer surfaces of the main body 1 affects the design appearance. It will be enhanced.

Since the naturally colored film 3 is formed by a coloring anodizing process, and the inner and outer surfaces of the main body 1 are colored differently, the main body 1 can be formed with a simple process without the need for expensive processing as in the past. It is possible to prevent food from burning on the inner surface of the main body 1, and even though the same anodic oxidation treatment is applied to both the inner and outer surfaces of the main body 1,
Since the inner and outer surfaces of the main body 1 can be colored differently, it has become possible to significantly enhance the aesthetic appearance of the pot product.
