Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorating method for forming a marble-like multicolored pattern on an object to be painted, such as a glass bottle containing cosmetics.

For example, containers for storing cosmetics and their lids are made by molding synthetic resin, glass, etc. into a predetermined shape. In order to further enhance the image of the product, it is necessary to decorate it in a manner suitable for use in cosmetics and the like.

In particular, there is a demand for containers, lids, etc. for high-end cosmetics to be decorated in a beautiful and elegant manner in order to match the image of high-end products and improve their commercial value.

For this reason, it has been conventional practice to form multicolored patterns on the surfaces of molded objects such as cosmetic containers and lids by painting. For example, silicone resin is applied to either the top paint or the base paint. There is a method in which two or more paints of different colors are mixed in a non-uniform state, and two or more paints of different colors are mixed in a non-uniform manner. A method of applying a multicolor pattern onto the object to be painted, or a method of applying an oil-in-water emulsion paint with a multicolored pattern to the object, as discovered by John and C. Shira, can create a multicolor pattern on the object. It has been adopted as a method for forming

However, with this type of conventional method, it is difficult to decorate with the desired color, the resulting pattern is monotonous and lacks variety, and the contours and boundaries of the pattern are unclear and unclear. However, it has disadvantages such as not being able to be decorated as a contour pattern, and similar patterns cannot be obtained, and it has been difficult to obtain multicolored patterns with decorative value.

The present invention has been made in view of the above circumstances, and its purpose is to provide a desired color to objects to be coated such as glass bottles, and to easily and reliably form a clear marble-like multicolored pattern. To provide a simple and efficient decorating method capable of obtaining at low cost a product having a multicolor pattern with a unique color tone that has a high color effect and decorative value and is unique in color.

That is, as a result of intensive research by the present inventors in order to improve the above-mentioned drawbacks, after dropping the water-soluble paint onto the object to be coated using a pipette, thin tube, etc., the water-soluble paint is applied while rotating the object to be coated. is a solvent or solvent in which an incompatible oil-based paint is dropped using a pipette, a thin tube, etc., and then the water-soluble paint is not dissolved, only the oil-based paint dissolves somewhat, but evaporates before it is completely dissolved. It was discovered that a beautiful and majestic pattern similar to astronomical stone can be obtained by dropping a dripping paint consisting of a resin and a coloring agent, and then washing with water to remove only the water-soluble paint, which led to the creation of the present invention. It is.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

1 in the figure is a glass bottle (object to be painted), and below this glass bottle 1
A case in which a multicolor pattern is formed on the surface of 0 will be explained.

First, the glass bottle 1 is subjected to a predetermined surface treatment such as degreasing, preferably preheated, and then a predetermined water-soluble paint is dripped onto the surface of the glass bottle 10 using a water-soluble paint dripping device 2 such as a pipette or a capillary. A water-soluble paint coating portion 3 is formed.

Note that this water-soluble paint coating portion 3 may be formed directly on the surface of the glass bottle 1, or may be formed on the glass bottle 1 after applying a predetermined surface coating such as painting with ceramic paint or the like. I don't mind if you do that.

Further, any water-soluble paint can be used, but it is necessary that it is incompatible with the oil-based paint described below.

When dropping a water-soluble paint onto the surface of the glass bottle 1, as shown in FIG. 2, the glass bottle 1 is rotatably supported on a predetermined rotating device (not shown).
While rotating the glass bottle 1, it is preferable to drop the water-soluble paint using a liquid dropping device 2 such as a pipette or a thin tube disposed above the glass bottle 1.

When the water-soluble paint is dripped while rotating the glass bottle 1 in this way, the paint dripped onto the surface of the glass bottle 1 flows slightly in the same direction, forming an oval or elliptical almost polka dot-shaped water-soluble paint application area 3. is formed.

After the desired paint application area 3 is formed, and before it is completely dry, while rotating the glass bottle 1,
An oil-based paint that is incompatible with the water-soluble paint is dripped onto the surface of the glass bottle 1 from an oil-based paint dropping device 4 such as a pipette or a thin tube.

In this case, the dropped oil-based paint is not compatible with water-soluble paints, and since the object to be painted (glass bottle) is rotating, these oil-based paints do not enter the application area 3 of each of the water-soluble paints. 5, that is, the water-soluble paint flows onto the glass surface where it is not applied, and the oil-based paint is applied to the area 6.
is formed.

Therefore, when oil-based paint is dropped in this way, the glass bottle 1
A state in which a spider web-like continuous oil-based paint application area 6 is formed on the surface, and approximately oval or elliptical water-soluble paint application areas 3 are formed separated from this oil-based paint application area 6. becomes.

Note that any oil-based paint mentioned above can be used as long as it is incompatible with the water-soluble paint and is compatible with the dripping material described below, but if the base of the area to which the oil-based paint is applied is inorganic. It is preferable to use paint for raster spraying, and it is also possible to use several types of oil-based paints to form multicolored patterns of various colors, and these oil-based paints may be used at the same time or in combination. It is also possible to drop them sequentially.

Next, after the oil-based paint film 6 is formed, the glass bottle 1 is rotatably supported on a predetermined rotating device (not shown), and the glass bottle 1 is rotated.

At the same time, a predetermined material is dropped onto the oil-based coating film 2 from a droplet device 7 such as a pipette or thin tube arranged above the glass bottle 1.

Examples of materials to be dropped include methyl ethyl ketone, toluene, isopropyl alcohol, ethyl acetate, and ethylene glycol monoethyl, which do not dissolve the water-soluble paint and dissolve the oil paint to some extent, but evaporate before it is completely dissolved. A dripping material consisting of a solvent such as ether, or such a solvent, a paint resin such as an acrylic resin or an epoxy resin, and a coloring agent is used.

Further, dripping materials such as the above-mentioned solvent and paint resin, or the above-mentioned solvent and coloring agent can also be used.

Then, while rotating the glass bottle 1 in this way, when a predetermined dripping material is dripped onto the water-soluble paint application section 3 and the oil-based coating film 6, the water-soluble paint is not dissolved in the dripping material,
Since it contains a solvent that dissolves the oil-based paint film to some extent but evaporates before it completely dissolves, the above-mentioned dripping material does not dissolve at all in the water-soluble paint coating portion 3, and the oil-based paint film is dissolved. While dissolving the paint film present in the dripping point in step 6, the oil-based paint melt is pushed to the periphery of the dripping point and spreads, and the dripped material is rotated so that it does not spread a little extra in the circumferential direction. , an oval or elliptical pattern 8 is formed in the oil-based coating film 6.

When the solvent in the dropped material evaporates, an oblong or elliptical pattern 8 is formed on the oil-based coating 6 as shown in FIG.

In this case, the periphery of these patterns is in a state where the melted material of the oil-based coating film 6 in the center of the pattern has moved concentrically, so the color is much darker than that of the oil-based coating film, and a thick outline is formed. Therefore, a sharp pattern with a boundary clearly distinguished from the oil-based coating film 6 can be obtained.

In addition, at this time, the coating film components in the dropped material remain uniformly within the outline of the oil-based coating film, and the dropped material does not protrude outside beyond this outline, resulting in a multicolored pattern with clear boundaries. is formed.

In addition, when a dripping paint containing a coloring agent is used as the dripping material, as shown in FIG. A coating film of a predetermined color B is formed.

Furthermore, when only a solvent is used as the dripping material, the solvent dissolves the oil-based paint within the contour of the oil-based paint film, and this dissolved paint moves to form the contour, as shown in Figure 8. As shown, the oil-based paint film of color a has an outline of color A, and a pattern of color a', which is lighter than the color of the oil-based paint film or is the color of the base material such as ceramic paint, is formed on the object to be painted. The situation is as follows.

Note that it is also possible to use dripping paints of various colors as the dripping material to form multicolored patterns of various colors, and these dripping paints can also be dropped simultaneously or sequentially.

Next, the glass bottle 1, on which the water-soluble paint coating portion 3, the oil-based coating film 6, and the dripping material coating film 8 are formed, is washed with water.

Then, only the water-soluble paint on the surface of the glass bottle 1 is dissolved and removed, and the oil-based paint and the dripped material remain on the surface of the glass bottle 1. Therefore, the water-soluble paint is washed away from the water-soluble paint application area 3, so that the base material is removed. At the same time, the oil-based paint application portion 6 and the dripping material application portion 8 flow slightly over the surface of the glass bottle 1 during the water washing, forming an irregular linear pattern.

After washing with water and drying or baking at a predetermined temperature and time, irregular linear oil-based paint application areas 6 (color a) and the water-soluble paint initially formed on the surface of the glass bottle 1 as shown in FIG. A marble-like or mottled pattern consisting of a cloud-like base revealing part 9 (color C) where the coated part 3 is removed and the base is exposed, and a dripped material coated part 8 (color B) formed in the oil-based paint coated part. A pattern is formed, and the glass bottle 1 is decorated in a beautiful and dignified manner.

In this case, the oil-based paint application area 6 is compatible with the dripping material but not with the water-soluble paint, and is not compatible with this even when washed with water, so the edges of the application area 6 are blurred. The oil-based paint application area 6 has a contour similar to Inuzumi Seishu Teru, and the dripping material application area 8 is formed within this application area 6, and the oil-based paint application area 6 and the dripping material A multicolor pattern is formed in which the applied portion 8 and the base material revealing portion 9 are clearly defined.

In the above embodiments, various desired patterns can be formed by changing the size of the nozzles such as pipettes and thin tubes, the number of nozzles, etc.

In addition, a multicolored pattern can be similarly formed on the surface of a predetermined molded object such as a plastic container instead of a glass bottle, and other configurations may be changed without departing from the gist of the present invention. do not have.

As described above, the present invention involves dropping a water-soluble paint onto an object to be painted, rotating the object, dropping an oil-based paint that is incompatible with the water-soluble paint, and then rotating the object. After dropping the material, which does not dissolve the water-soluble paint and dissolves the oil-based paint somewhat, but evaporates before it completely dissolves, the material is washed with water to remove only the water-soluble paint. It is characterized by forming a multicolored pattern on the object to be painted.

Therefore, according to the present invention, there are irregular linear oil-based paint application areas, cloud-like base material exposed areas where the initially formed water-soluble paint is removed and the base material is exposed, and within the outline of the oil-based paint application areas. A marble-like or mottled pattern is formed by applying the dripped material in an almost polka dot pattern, and the object to be coated is decorated with a beautiful and majestic feel.

In addition, since the oil-based paint is dripped while rotating the object to be painted, there is no inconvenience of only being able to apply it to one side as in the case of printing, and the entire surface can be easily and reliably applied, making it possible to freely apply a wide variety of colors. It can be selected, and it is not monotonous as is the case with paints such as lacquering, but has a rich variety of subtle color tones, and has a marble-like pattern, giving it a color effect.
A multicolored pattern with a highly decorative effect and unique bright color tone is formed on the object to be coated.

In addition, according to the present invention, since the specified paint is dripped while rotating the object to be painted, it is possible to paint the shoulder of a glass bottle at the same time as painting the body of the glass bottle. A product having a multicolor pattern can be obtained at low cost, and an object to be coated such as a glass bottle can be decorated with a multicolor pattern using an easy-to-operate and efficient method.

Hereinafter, the present invention will be specifically explained with reference to Examples.

Example The object to be coated was a glass bottle whose surface had been previously coated with ceramic paint. After preheating the object, the following water-soluble paint methylcellulose water 971 was dripped onto the surface of the object with a pipette. , While rotating the object to be painted, use A for raster spraying, which is incompatible with water-soluble paints.
7802 Green (manufactured by Nippon Engelhardt Co., Ltd.) oil-based paint was dripped with a pipette, and then while rotating the object to be painted,
Next dropping material Acrylic resin Br105 20S' Methyl ethyl ketone sof? Glass color S-1173101 was added dropwise with a pipette, and then washed with water to remove only the water-soluble paint, followed by baking at 600°C for 30 minutes to obtain a painted product with a three-color pattern.

As shown in Figure 7, this painted object has a color a of the irregular linear oil-based paint area, a color C of the cloud-like base exposed area (color of the ceramic paint film), and an oil-based color C. It had a three-color large buried stone pattern with color B of the dripping material formed in the paint application area, and was beautiful and decorated the car.
