Among these cups, a double cup having a double cup wall is known. The double cup is formed in two layers, an inner part forming the inside of the cup and an outer part forming the outside of the cup, and a space part between the inner part and the outer part. Is produced.

Due to this structure, the inner part is not directly affected by the external temperature, so that the temperature of the contents contained in the cup can be maintained for a considerable time.

The double cup is often manufactured using a metal material, and when using a metal material, a double cup is usually manufactured using stainless steel.

Stainless steel double cups are manufactured and sold in a variety of applications and designs due to the advantages of little damage and easy storage and portability. In most cases, this stainless steel double cup is formed by a transfer printing method on the outside of a printed layer made of various patterns, letters, and pictures.

However, when the printing layer is formed on the stainless double cup surface as described above, since the printing method is directly printed on the metal surface, the colors of the printing layer may be heterogeneous, and the color may not be clearly seen visually.

In addition, the conventional stainless steel double cup has a disadvantage that the texture of the ceramics can not appear due to the nature of the metal material.

The present invention has been proposed to solve the conventional problems as described above, and an object of the present invention is to provide a stainless double cup and a method of manufacturing the same that can exhibit the color and color tone of the printing layer formed on the surface of the cup well have.

The stainless double cup proposed by the present invention comprises a double cup body made of stainless steel and having an inner portion forming the inside of the cup and an outer portion forming the outside of the cup and a space portion between the inner portion and the outer portion; A first coating layer coated on the outer surface; A printing layer formed on the first coating layer; It provides a stainless steel double cup comprising a.

The first coating layer is off-white, a second coating layer made of a coating layer is formed on the outside of the first coating layer, the second coating layer is made of a pearl pigment.

In addition, the present invention comprises the steps of manufacturing a double cup made of stainless steel and the inner portion forming the inside of the cup and the outer portion forming the outside of the cup and the space portion between the inner portion and the outer portion; Painting a first coating layer on an outer side of the double cup; Firing the first coating layer; Forming a printing layer on the dried first coating layer; It provides a stainless steel double cup manufacturing method comprising a.

In the first coating layer coating step, an off-white pigment is used. After the first coating layer firing step, the second coating layer coating step is further performed to make the texture of the printing layer smooth and colorful. In this second coating layer coating step, a pearl pigment is used.

The stainless steel double cup according to the present invention may be coated with an off-white first coating layer on the outer side to express the color of the printed layer without dissimilarity and to clearly indicate the color tone of the printed layer, thereby improving product quality.

In addition, because of the first coating layer of the off-white series, stainless steel material can be expressed as a porcelain texture, thereby producing a luxurious image.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a process chart according to a stainless double cup manufacturing method according to the present invention, Figure 2 is a cross-sectional view of the initial state of a double cup manufactured to manufacture a stainless double cup of the present invention, Figure 3 is in accordance with the process of FIG. Sectional drawing which shows the process which manufactures the stainless steel double cup of this invention sequentially is shown.

As shown in order to manufacture a stainless double cup according to the invention as shown in Figure 2 using the stainless steel as shown in the upper portion and the inner portion (2) forming the inside of the cup and the outer portion (4) forming the outside of the cup and A stainless double cup is produced through the step P1 of manufacturing a double cup between these inner and outer portions of the space portion 6.

In the double cup manufacturing step (P1) it can be manufactured by a method commonly used in the art, so a detailed description thereof will be omitted.

When a double cup made of stainless steel is manufactured as described above, a step (P2) of coating the first coating layer 8 on the outer side portion 4 of the double cup is performed.

The first coating layer 8 forms a background color before forming the printing layer on the outer surface of the double cup. When the first coating layer 8 subsequently forms the printing layer on the first coating layer, Not only does the color of the printed layer not look heterogeneous, but the color can be clearly seen visually.

The coating of the first coating layer 8 may be made in various colors. In the present invention, the first coating layer 8 is formed by using a pigment of an off-white color so as to maximize the above characteristics.

When the first coating layer 8 is formed in an off-white series, the appearance of the double cup may be similar to that of a porcelain feel. In addition, when the printing layer is formed on the surface of the first coating layer 8 through the printing layer forming step described later in detail, the color and hue of the printing layer can be more clearly and clearly expressed.

That is, when the first coating layer 8 is formed in an off-white series, the color of the printing layer can be displayed without any heterogeneity, and the color tone of the printing layer can be clearly expressed even if the printing layer is made of any color.

The double cup coated with the first coating layer 8 through the first coating layer coating step P2 as described above is placed in a firing furnace and the like, and the baking step (P3) is performed for about 20 to 40 minutes at a temperature of 150 ° C to 250 ° C. Is performed, the coating film of the first coating layer 8 is dried and fired and fixed to the outer side 4 of the double cup (see FIG. 3A).

At this time, if the temperature condition and the time condition are lower than the set value lower limit value, the first coating layer 8 is hardly adhered to the outer portion 4, and if it is higher than the upper limit value, the first coating layer 8 may be burned out and extinguished. It is preferable to proceed to the above conditions.

When the first coating layer 8 is completely dried, the coating state of the first coating layer 8 is checked. This first coating layer coating step (P2) may be made in one process or may be made in two or more processes.

When the firing of the first coating layer 8 is completed in this way, a second coating layer coating step P4 of forming the second coating layer 10 on the first coating layer 8 is performed.

The second coating layer 10 is to make the texture of the printing layer to be formed in the next process smooth and colorful, a transparent or translucent pigment may be used. In the present invention, a pearl pigment is used as the pigment used when the second coating layer 10 is formed.

Since the pearl pigment has a structure in which multiple layers of thin films overlap, when light shines on each of the subdivided pearl pigments, each layer reflects only the strong color of blue light, or only the strong color of red light is subtle. Selective absorption or reflection of light has the property of changing its brilliance.

Therefore, since the second coating layer 10 is made of a pearl pigment, it is possible to obtain high quality and soft feeling of the printing layer to be printed on the surface thereof, and to form the printing layer by combining with the first coating layer 8 formed on the bottom surface thereof. While making it more colorful, a new color effect can be expressed to enhance the aesthetics of the double cup.

When the second coating layer 10 is applied to the first coating layer 8 by performing the second coating layer coating step P4 as described above, the cup is placed in a firing furnace or the like at about 1 to 3 at a temperature of 280 ° C to 320 ° C. The baking step P5 of about minutes is performed. Then, as the coating film of the second coating layer 10 is dried and baked, the second coating layer 10 is coated on the outside of the first coating layer 8 (see FIG. 3B).

At this time, if the temperature condition and time condition are lower than the set value lower limit value, the second coating layer 10 is hardly adhered to the first coating layer 10. If the temperature is higher than the upper limit value, the second coating layer 10 burns and disappears. It may be better to proceed under the above conditions.

When the second coating layer 10 is completely fired, the coating state of the second coating layer 10 is checked to check whether there is any part to be corrected and supplemented.

As described above, when the second coating layer 10 is formed on the surface of the first coating layer 8, the printing layer forming step P6 is performed to form the printing layer 12 on the second coating layer 10.

The printed layer 12 is made of a variety of patterns, letters, pictures, etc., it is also made in a variety of colors.

The printing layer 12 formed through the printing layer forming step P6 may be formed by a transfer printing method using a transfer paper or a direct printing method using a pigment or the like.

Transfer printing and direct printing may be applied to a method commonly used in the printing field, and the printing layer may be formed by other methods.

When the printing layer 12 is formed on the surface of the double cup as described above, the baking step P7 is performed. At this time, the double cup on which the printing layer 12 is formed is subjected to approximately 2 to 4 at a temperature of 200 ° C. to 240 ° C. in a firing furnace. After firing, the printing layer 12 adheres to the second coating layer 10 (see FIG. 3C).

At this time, if the temperature and time conditions are lower than the set value lower limit value, the printed layer 12 is hardly adhered to the second coating layer 10, and if it is higher than the upper limit value, the printed layer 12 may burn out and disappear. It is good to proceed under conditions.

When the printed layer 12 is formed as described above, the manufacturing of the double cup is completed, and if necessary, as shown in FIG. 4, the lid 14 and the lid on which the spout 16 is formed while being detachably seated on the opening of the cup ( 18) may be further provided.

In the above process, the second coating layer 10 is coated on the first coating layer 8, and the printing layer 12 is formed on the second coating layer 10, but the present invention is not limited thereto. Coating layer The double cup may be manufactured by a method of forming the printing layer 12 on the first coating layer 8 by omitting the second coating layer 10 by omitting the coating step P4 and the firing step P5. have.

While the preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
