Abstract

PURPOSE: A stainless kitchen utensil having an etched intaglio surface pattern is provided to apply a quiet gloss and a natural pattern of the stainless steel to a kitchen utensil by etching the surface of a stainless cooker with iron chloride. CONSTITUTION: A pattern of various colors and shapes is inserted to the surface of a stainless kitchen utensil form(10) by screen printing. The pattern is treated with chemical etching. Thus, a prominence and depression pattern(100) is formed on the surface of the stainless kitchen utensil. A surface coat layer(30) and an inner coat layer(20) are treated in a coating process. After a rinsing process, a completed stainless kitchen utensil is produced.

Description

Stainless steel kitchen appliance having engraving erosion patten on its surface}

The present invention relates to stainless steel kitchen utensils having a concave surface pattern by the corrosion method of the kitchen utensils made of a stainless steel of high strength and smooth surface processing.

More specifically, the kitchen utensils can be made of stainless steel commonly used or handled in the kitchen, such as pots, pots, kettles and pans. Hospitality. Types of containers such as bowls, cups, thermos and trays, kitchen utensils such as their lids or handles, kitchen utensils such as ladles and cutlery used to move food, or stainless steel plates such as trash cans used indoors. This applies to all possible products.

In the manufacture of stainless steel kitchen utensils used for the above uses, the screen printing pattern is inserted into the surface of the stainless steel kitchen utensils made by chemical corrosion with iron chloride, etc. to make the surface of the corroded stainless steel material intaglio Corrosion and unevenness is made only on the surface, as well as external aesthetics in terms of function, the interior of the stainless steel maintains the original smooth surface intact, and the effect is also high.

In particular, stainless steel kitchen utensils have a smooth surface and high strength, so they are used to shape kitchen utensils with a very thin thickness. Transferring letters, patterns or colors by various methods of corrosion using iron chloride on the surface After etching or coating treatment, the engraved corrosion part was made to show a soft light or various colors.

In general, stainless steel kitchen utensils are very hard and the surface is smooth, so the kitchen utensils are used a lot, but the strength of the material is very strong, so the thickness of the stainless steel container is used thinly. It is common practice to form irregularities by press (marking process) work in order to insert the pattern into the pattern.However, when the pattern is made in such a state, the surface is compressed so that the shape of the inner surface is protruded. In addition, when used as food containers, food residues were caught inside the protrusions, which was very unsanitary.

In particular, not only residues such as food residues may remain on the protruding outer surface, but also damage to the pattern itself due to abrasion of the protruding outer surface during cleaning, and in the case of prolonged use, the peeled pattern peels violently, resulting in aesthetic or hygienic use. It was not good.

Therefore, the object of the present invention is to maintain the elegance of the stainless steel itself on the outside while maintaining the elegance of the kitchen utensils produced by using a stainless steel of a smooth surface material as a raw material is very strong and does not cause irregularities due to the formation of patterns on the inside The pattern of various colors and shapes is formed by engraving the pattern by the corrosion of iron chloride on the surface of stainless steel container, and the soft luster and natural pattern of stainless steel are applied to the kitchen utensils themselves.

* Description of Signs of Main Parts of Drawings *

1: molded article 10: stainless steel material

Hereinafter, described in detail by the manufacturing process block diagram of Figure 1 attached to a preferred embodiment of the present invention.

First of all, the screen inserting method (2) is inserted into the surface of the molded article (1) of the kitchen utensils made of stainless material. In the state in which the uneven pattern 100 is molded, the coating layers 20 and 30 on the inner and outer surfaces of the kitchen utensils are treated with coatings (4) in a state of having various colors, and then cleaned and cleaned (5). (6).

FIG. 2 is a diagram illustrating a configuration state according to a cross-sectional view of FIG. 3 in which a portion A is enlarged as an embodiment of the present invention is applied to a fry pen.

Various patterns are inserted by using screen printing on the surface of kitchen utensils that are formed by using a thin stainless steel, and the uneven patterns (100) are formed on the surface of stainless kitchen utensils by a chemical corrosion method using chemicals such as iron chloride. In the coating (4) treatment with the surface coating layer 30 and the inner coating layer 20 is characterized in that the concave-convex pattern 100 by the corrosion method is engraved intaglio on the surface.

As the actual product of the present invention to be applied to all kitchen utensils that can be molded using stainless steel,

Due to the characteristics of the material of stainless steel itself, it is very strong, so it is manufactured and used in various kitchen appliances in consideration of the fact that no deformation or damage of the product occurs even when manufactured to a thin thickness. By applying the corrosion method to the surface of the kitchen utensils made of stainless steel to form a negative pattern by corrosion only on the surface without any change on the inner surface of the kitchen utensils.

In the present invention as described above, the kitchen utensils are made of stainless material, and thus the kitchen utensils are produced in a very thin state by the strength of the stainless steel itself, so that the weight is not only light but also firm and does not cause crushing or damage.

In addition, intaglio glyphs of various colors and shapes engraved by the corrosion method on the surface are not damaged in any case,

In particular, the surface engraved pattern formed by the corrosion method does not cause any protrusions or deformation of the inner surface at all, and food residues or unsanitary substances cannot be stuck even when using kitchen utensils for a long time.

Claims (1)

Stainless steel kitchen utensils (1) are made of stainless steel by inserting patterns (2) into various colors and shapes by screen printing, etc., and chemically corroded with chemicals such as iron chloride (3). The surface coating layer 30 and the inner coating layer 20 are treated in the coating (4) process in the state where the uneven pattern 100 is formed on the surface of (10), followed by the washing (5) process. Stainless steel kitchen utensils having an intaglio surface pattern characterized in that the manufacturing (6).
