厨房用途等の弗素樹脂被覆物の目盛、模様、文字等の表
示方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a fluororesin coating for kitchen use such as an inner pot such as a jar rice cooker, a heating jar, a rice cooker, a sticker, a pot, a frying pan, a hot plate and the like. The present invention relates to a method of displaying scales, patterns, characters, and the like of objects.
「従来の技術」 従来、弗素樹脂被覆物に目盛等を表示する方法として
は、被覆物にプレス等により物理的に凹凸を設け、その
陰影を利用した方法、すなわち刻印によるものしかなか
った。[Related Art] Conventionally, as a method of displaying a scale or the like on a fluororesin coating, there has been only a method of physically providing irregularities on the coating by a press or the like and using the shadow, that is, a method of engraving.
これは、弗素樹脂の非粘着性のためにその表面に印刷
による目盛等の表示ができないためである。又、仮にこ
れが可能になったとしても、印字部の非粘着性が低下す
ることになるので、厨房用途、例えば炊飯器の内釜に用
いる場合この部分に米が粘着し、好ましくない。This is because scales or the like cannot be displayed by printing on the surface of the fluororesin due to its non-adhesiveness. Even if this is possible, the non-adhesiveness of the printed portion will be reduced. Therefore, when it is used in a kitchen, for example, in an inner pot of a rice cooker, rice sticks to this portion, which is not preferable.
「発明が解決しようとする課題」 このような理由から炊飯器内釜は、すべて刻印による
表示がなされてきたが、この方法にも重大な問題点があ
る。"Problems to be Solved by the Invention" For such a reason, all the rice cooker inner pots are displayed by engraving, but this method also has a serious problem.
第１に、刻印部は非常に大きな曲率で被覆物が変形さ
れるため、弗素樹脂被覆も同時に延伸され、基板との接
着界面の剥離や被膜のピンホール、クラック等の発生が
おこり易く、この部分から水分や飯汁が侵入し、基板の
腐蝕や、被膜剥離、変色等をおこすことになる。First, since the coating is deformed with a very large curvature at the stamped portion, the fluororesin coating is also stretched at the same time, and peeling of the adhesive interface with the substrate and occurrence of pinholes and cracks in the coating are likely to occur. Moisture and rice juice enter from the part, causing corrosion of the substrate, peeling of the film, discoloration, and the like.
第２に凹凸による陰影によるため、表示が見にくいこ
とである。Second, display is difficult to see because of shading due to unevenness.
飯器内釜は近年時に多機能化し、それに伴って目盛等
の表示が炊飯用の１種のみならず、赤飯用、おじや用、
もち米用等多種にわたり、３個所、４個所に刻印するこ
とが多くなってきているため、これらの問題が顕在化し
てきている。In recent years, rice cookers have become multifunctional in recent years, and as a result, the scale and other indications are displayed not only for rice cooking, but also for red rice, uncle,
These problems are becoming more apparent as stamps are often imprinted at three and four locations across a wide variety of types such as sticky rice.
上記に鑑み、本発明はこの様な問題点を解消するため
開発された目盛、模様、文字等の表示方法である。In view of the above, the present invention is a method of displaying scales, patterns, characters and the like developed to solve such problems.

の目盛、模様、文字等の表示方法である。[Means for Solving the Problems] That is, the method of displaying the scales, patterns, characters and the like of the fluororesin coating of the present invention is described with reference to FIG. 1 by etching the surface of an aluminum or aluminum alloy plate (1). After that, an anodic oxide film (2) is formed on the anodic oxide film, and a scale, a pattern, and a heat-resistant resin-based paint are applied to a predetermined position on the surface of the anodic oxide film which is designed in advance to a desired position after press molding. After forming characters or the like (3) by printing or painting, a fluorine resin layer (4) substantially free of a filler is provided on the entire surface of the etching surface including the printed or painted portion, and this is press-molded. A method of displaying scales, patterns, characters and the like of a fluororesin coating, characterized by obtaining a fluororesin coating such as a rice cooker and copper.
「作用」 本発明の特徴は次の３点である。[Operation] The features of the present invention are the following three points.
エッチングの表面に目盛、模様、文字等を印刷もし
くは塗装した上に更に弗素樹脂がコーティングされてい
る為、その表示部分の表面の非粘着性が失なわれていな
い。Since the scales, patterns, characters and the like are printed or painted on the etched surface and further coated with a fluororesin, the non-adhesiveness of the display portion surface is not lost.
弗素樹脂層には充填剤を含んでいないので、印刷も
しくは塗装した目盛、模様、文字等が表面から目視で明
瞭にわかる。Since the fluorine resin layer does not contain a filler, printed or painted scales, patterns, characters, and the like can be clearly seen from the surface.

板の腐食や被膜剥離、変色等を発生させることが防止で
きる。Scales, patterns, characters, etc. are formed by printing or painting with a heat-resistant resin paint at specified positions on the etching surface designed in advance to the desired position after press molding, so this fluororesin coating is pressed. Not only can scales, patterns, characters, etc. be displayed at desired positions on the press-formed product simply by molding, but also in the display section of the scales, patterns, characters, etc., moisture and rice juice invade from this part, causing corrosion of the substrate. And peeling of the coating, discoloration and the like can be prevented.

はなく良好であった。This fluororesin coating was press-formed to form an inner pot of a jar rice cooker. The fluorine resin coating had good adhesive strength and did not peel off even by press molding. The scales and characters written on the flat plate before pressing were located at desired positions on the press-formed product, and the character portion was black with respect to the gray base material, and very easy-to-read scales and character display were obtained. The non-adhesiveness of the surface where the characters were written on the base was not different from the other portions and was good.
