Description

The present invention relates to a full-color coloring method for glass bottles and a full-color colored glass bottle.

Conventionally, there has been a technique for coloring glass bottles such as glassware and bottles by adding an uneven pattern. For example, Japanese Patent Application Laid-Open No. 58-176147 (Patent Document 1) discloses a coloring decoration method for glassware in which a pattern is engraved on the back surface of the glassware by sandblasting and a transparent colorant is poured into the engraved pattern to color the glassware. Has been done. As a result, not only is it easy to obtain a desired pattern on the glassware, but the pattern is extremely sharp, and even fine lines can be colored extremely clearly.

Further, Japanese Patent Application Laid-Open No. 63-233897 (Patent Document 2) describes a step of applying a desired coloring to a member (glass body) to be decorated, and a pattern of characters, line drawings, etc. to be formed on the colored surface. Correspondingly, a process of masking, a process of sandblasting the colored surface and masking to scrape the colored surface and members other than the masking part, and a process of removing the masking and exposing the hidden colored surface by masking are carried out in a series. A method of forming a decorative surface to be used is disclosed. As a result, when the masking is removed, the pre-colored portion is exposed and a colored pattern is exposed, and the outline portion of this pattern is raised from the portion scraped by sandblasting to create a three-dimensional effect. Further, since the member is colored, then masked and sandblasted, it is possible to save the trouble of coloring according to the contour of the pattern as in the conventional case, and further, the colored paint oozes out from the contour of the pattern, and the contour portion. The problem of obscuring is not occurring.

Further, in Japanese Patent Application Laid-Open No. 10-194782 (Patent Document 3), the surface of the glassware is sandblasted to form fine uneven surfaces and processed into opaque sliding glass, or the glassware is treated with hydrogen fluoride. When the surface is roughened and processed into opaque sliding glass, and then X indicates an inorganic substance and R indicates an organic group with respect to 100 parts of sekigo lacquer at an arbitrary part of the glassware processed into the Taimei. Whether to form a transparent part of a desired pattern by hand using a brush, a brush, etc. with a paint obtained by mixing 1 to 5 parts of a silane coupling agent having a chemical structure of X, Si, and (OR) 3. Disclosed is a glass product with lacquer decoration obtained by transferring and forming a transparent portion of a desired pattern by screen printing with a silk screen mold. As a result, the glass product can be obtained by a relatively simple method, and a fine transparent pattern or a transparent lacquer pattern with a deep feeling can appear on the opaque glass surface, and the color and luster peculiar to lacquer are extremely elegant. It is said that it has a decorative property. Further, even if the washing is repeated, the lacquer coating film does not peel off from the decorative surface and the lacquer coating film has good adhesion, so that it can withstand the same usage as general tableware. Further, since the surface of the product has an adhesive coating film layer decorated with lacquer, the impact resistance is improved and the glass product is said to have a reinforcing effect.

Further, Japanese Patent Application Laid-Open No. 2001-72441 (Patent Document 4) discloses a method for producing a colored glass bottle in which a resin coating layer is formed on a glass bottle and then the resin coating layer is dyed to color the bottle. The resin coating layer is formed of, for example, a thermosetting acrylic resin clear. Further, after roughening the surface of the glass bottle by sandblasting or the like, a resin coating layer is applied. As a result, even if the thickness of the resin coating layer formed on the glass bottle is uneven, it does not affect the color unevenness, the resin coating layer obtains uniform coloring, and a good coloring bottle without color unevenness is obtained. It is said that it can be done. Further, it is said that the adhesiveness between the resin coating layer formed on the glass bottle and the glass bottle is improved, and the life of the colored bottle can be extended.

Japanese Unexamined Patent Publication No. 58-176147 Japanese Unexamined Patent Publication No. 63-23897 Japanese Unexamined Patent Publication No. 10-194782 Japanese Unexamined Patent Publication No. 2001-72441

As mentioned above, there are many techniques for patterning and coloring glass bottles or glassware. In the coloring technique of a glass bottle, the surface of the glass bottle is usually sandblasted and then a paint is applied to color the bottle. In this case, there is a problem that the base color of the paint loses to the ground color of the glass bottle and is mixed, and the color of the paint does not become vivid. In particular, even if the paints are painted in multiple colors, there is a problem that it is difficult to obtain the goodness of the multiple colors due to the presence of the ground color of the glass bottle.

Further, ordinary paints have a weak durability, and there is a problem that they are easily peeled off from the surface of a glass bottle when some force such as washing with water is applied.

Such a problem cannot be solved by the techniques described in Patent Documents 1-4 described above.

Therefore, the present invention has been made to solve the above problems, and is a glass bottle that has durability, realizes vivid full-color coloring, and can enhance the decorativeness and artistry of the glass bottle. It is an object of the present invention to provide a full-color coloring method and a full-color colored glass bottle.

The full-color coloring method for a glass bottle according to the present invention includes a pasting step, a first peeling step, a masking step, a sandblasting step, a base color coating step, a topcoat color coating step, and a second peeling step. To be equipped. The pasting step corresponds to either one of the line portion constituting the line of the pattern and the closed region portion divided by the line of the pattern, the masking film having an adhesive layer, and the line portion and the closed region portion. A masking tape composed of a non-adhesive film having no adhesive layer, which corresponds to either one of the above and the other, is attached to the surface of the glass bottle to be treated. In the first peeling step, the attached masking sticker is peeled off, the portion where the masking film remains on the treatment target portion is designated as an uncolored portion, and the portion where the surface of the glass bottle is exposed on the treatment target portion is designated as a colored portion. To do. In the masking step, the entire surface of the glass bottle other than the portion to be processed from which the masking seal has been peeled off is masked with a masking member. In the sandblasting treatment step, the processing target portion of the glass bottle after masking is sandblasted to form a fine uneven surface on the colored portion. In the base color coating step, the base color resin coating paint was applied to the portion to be processed of the glass bottle subjected to the sandblasting treatment, and the base color resin coating paint was solidified on the fine uneven surface of the colored portion. An opaque base color coating layer is formed. In the topcoat color coating step, a plurality of topcoat color resin coating paints are separately applied to the base color coating layer of the colored portion of the glass bottle according to the pattern, and the topcoat is applied to the base color coating layer. The color resin coating paint forms a solidified opaque topcoat color coating layer. In the second peeling step, the entire masking member of the glass bottle is peeled off, and the masking film of the uncolored portion of the glass bottle is peeled off.

The full-color colored glass bottle according to the present invention includes a pattern, a convex portion, a concave portion, a base color coating layer, and a top coat color coating layer. The pattern is provided on a specific part of the surface of the glass bottle. The convex portion corresponds to either one of the line portion forming the line of the pattern and the closed region portion divided by the line of the pattern, and has the same height as the surface of the glass bottle. The ground color is the same as the surface. The concave portion corresponds to either one of the line portion and the closed region portion, and is formed deeper than the surface of the glass bottle, and a fine uneven surface is formed. The base color coating layer is formed on the fine uneven surface of the recess and is opaque. The top coat color coating layer is formed by being separately painted on the base color coating layer according to the pattern, and is plural and opaque.

According to the present invention, it is possible to realize durable and vivid full-color coloring, and to enhance the decorativeness and artistry of a glass bottle.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings for the purpose of understanding the present invention. It should be noted that the following embodiments are examples that embody the present invention, and do not have a character that limits the technical scope of the present invention.

The configuration and execution procedure according to the embodiment of the present invention will be described with reference to FIGS. 1 to 14. First, as a preliminary step, the operator prepares a glass bottle to be colored in full color, cleans the surface of the glass bottle with a cleaning liquid (for example, methanol), and then uses a heating means H such as a dryer as shown in FIG. 2A. The surface S of the glass bottle 1 is dried. As a result, the surface S of the glass bottle 1 is cleaned.

Next, the operator corresponds to either the line portion forming the pattern line or the closed region portion divided by the pattern line, and the masking film having an adhesive layer and the line portion and the closed region portion A masking tape composed of a non-adhesive film having no adhesive layer corresponding to either one of the above and the other is prepared.

For example, as shown in FIG. 2B, the basic configuration of the masking sticker 10 is a line portion a of a pattern (here, for ease of understanding, for example, an ellipse) with respect to one surface of the base film 11. A corresponding masking film 12 and a non-adhesive film 13 corresponding to the closed region portion b of the pattern are provided. One surface of the masking film 12 faces the base film 11 and is peeled off from the base film 11, and the other surface of the masking film 12 includes an adhesive layer. On the other hand, one surface of the non-adhesive film 13 faces the base film 11 and adheres to the base film 11, and the other surface of the non-adhesive film 13 does not have an adhesive layer. As a result, only the masking film 12 can be adhered. Here, the pattern is not particularly limited, and characters, figures, symbols, etc. can be included in addition to animals, plants, people, landscapes, and the like. Further, in the embodiment of the present invention, the masking film 12 corresponds to the line portion a and the non-adhesive film 13 corresponds to the closed region portion b. However, depending on the type of the pattern, the masking film 12 corresponds to the closed region portion b. The non-adhesive film 13 may be made to correspond to the line portion a.

Then, the operator attaches the masking sticker 10 to the processing target portion St of the surface S of the glass bottle 1 (FIG. 1: S101). Here, the processing target portion St means a portion that is subjected to sandblasting or full-color coloring, as will be described later.

The masking sticker 10 is composed of a pattern in which a woman holds a brush, for example, as shown in FIG. 2C. Since the surface S of the side surface of the glass bottle 1 is curved on the circumferential surface, the operator aligns the masking seal 10 with the processing target portion St of the glass bottle 1 and manually aligns the masking seal 10 with the surface S of the side surface of the glass bottle 1. Paste it carefully.

Here, as shown in FIG. 3A, it is preferable to use the rectangular plate material B and press the masking sticker 10 attached to the surface S of the glass bottle 1 with the end portion of the plate material B to attach it. As a result, the masking sticker 10 can be evenly attached to the processing target portion St of the glass bottle 1.

When the operator completes the application of the masking sticker 10, the applied masking sticker 10 is then peeled off, and the portion where the masking film 12 remains on the treatment target portion St is designated as the uncolored portion Ca, and the treatment target portion St. The portion where the surface of the glass bottle is exposed is designated as the colored portion Cb (FIG. 1: S102).

For example, when the masking seal 10 is peeled off, as shown in FIG. 3B, only the masking film 12 of the masking seal 10 remains in the processing target portion St of the glass bottle 1, and the base film 11 and the non-adhesive film 13 of the masking seal 10 are the glass bottle 1. It is peeled off from the processing target part St of. The portion where the masking film 12 remains is the uncolored portion Ca which is not the target of coloring, and the portion where the masking film 12 does not remain is the colored portion Cb which is the target of coloring.

When the operator completes the peeling of the masking sticker 10, the entire surface of the glass bottle 1 other than the processing target portion St from which the masking sticker 10 has been peeled off is masked with a masking member (FIG. 1: S103).

The masking member is not particularly limited, and examples thereof include a soft film Ma and a masking tape Mb, as shown in FIG. 3C. First, the operator attaches a soft film Ma to the periphery of the processing target portion St of the glass bottle 1 to surround the glass bottle 1, and winds the entire surface of the glass bottle 1 other than the processing target portion St with the soft film Ma. Then, it is preferable that the operator attaches the masking tape Mb so as to surround the peripheral edge of the processing target portion St and fixes the soft film Ma. Thereby, the entire surface of the glass bottle 1 other than the processing target portion St can be protected.

Here, the adhesive layer of the masking film 12 of the uncolored portion Ca may protrude and exist in the colored portion Cb. Therefore, as shown in FIG. 4A, the operator sprays the cleaning liquid Wa (for example, methanol) on the treatment target portion St, wipes the cleaning liquid of the treatment target portion St with a wiping member Wb such as paper, and wipes the cleaning liquid on the colored portion Cb. It is preferable to remove the existing adhesive layer. As a result, in the subsequent sandblasting treatment, the possibility that sand or the like adheres to the adhesive of the colored portion Cb can be eliminated, and the sandblasting treatment for the colored portion Cb can be uniformly performed.

When the operator completes the masking, next, the masked glass bottle 1 is sandblasted to form a fine uneven surface on the colored portion Cb (FIG. 1: S104).

The method of sandblasting is not particularly limited, and examples thereof include commercially available sandblasting devices. The operator accommodates the masked glass bottle 1 in the processing chamber of the sandblasting apparatus, sets the sand spraying pressure to the first value, and sets the spraying portion Sp as the processing target of the glass bottle 1 as shown in FIG. 4B. Sandblasting is performed by spraying sand from the spraying portion Sp onto the portion St to be processed so as to face the portion St.

Here, since the area of sand that can be sprayed by the spraying portion Sp is limited to a predetermined area, the operator gradually moves the spraying portion Sp in the vertical direction of the glass bottle 1 to process the portion St. The glass bottle 1 can be scanned evenly in the vertical direction, or the glass bottle 1 can be rotated little by little in the horizontal direction of the glass bottle 1 to scan the sprayed portion Sp evenly in the horizontal direction of the glass bottle 1 with respect to the processing target portion St. Then it is preferable. This makes it possible to form fine uneven surfaces having the same depth for all of the colored portions Cb. As shown in FIG. 5A, the uncolored portion Ca of the portion St to be processed by one sandblasting treatment is equivalent to the surface S of the glass bottle 1 without forming a fine uneven surface due to the protection of the masking film 12. The height remains the same, and the colored portion Cb is formed deeper than the surface of the glass bottle, and a fine uneven surface is formed. In particular, since the uncolored portion Ca corresponds to the line portion of the pattern and the colored portion Cb corresponds to the closed region portion of the pattern, it is understood that the pattern appears to be three-dimensionally raised.

Here, it is possible to form a fine uneven surface on the colored portion Cb even by performing the sandblasting treatment once, but in the present invention, by performing the sandblasting treatment twice or more, the colored portion Cb is fine. It is preferable to form the uneven surface deeper to a specific depth (for example, 0.5 mm or the like). As a result, even if the base color is applied to the colored portion Cb and the top coat color is further applied, a predetermined depth can be provided between the colored portion Cb and the uncolored portion Ca after the two colors are applied. It becomes possible, and it is possible to further express the three-dimensional decoration of the pattern.

Here, the second and subsequent sandblasting treatments are not particularly limited, but for example, in the second and subsequent sandblasting treatments, it is preferable to perform the sandblasting pressure higher than the sand blowing pressure of the first sandblasting treatment. This makes it possible to cut deeper and more uniformly on the fine uneven surface uniformly formed by the first sandblasting treatment.

For example, the operator sets the sand spraying pressure to a second value higher than the first value, and as shown in FIG. 5B, the spraying portion Sp is opposed to the processing target portion St of the glass bottle 1 and sprayed. Sand is sprayed from the portion Sp onto the portion St to be processed to perform sandblasting. Then, it is preferable that the operator gradually moves the spraying portion Sp in the vertical direction of the glass bottle 1 or rotates the glass bottle 1 in the horizontal direction of the glass bottle 1 little by little to spray sand evenly on the portion St to be processed. This makes it possible to further form a fine uneven surface deeper in the colored portion Cb. As shown in FIG. 6A, in the colored portion Cb of the second sandblasting treatment, fine uneven surfaces are formed deeper than in the colored portion Cb of the first sandblasting treatment, while in the uncolored portion Ca, the uncolored portion Ca is formed. Since the masking film 12 is present, no fine uneven surface is formed. As a result, it is understood that the uncolored portion Ca (here, the line portion of the pattern) is highlighted and emphasized. The same applies to the second and subsequent sandblasting treatments.

Now, when the operator completes the sandblasting treatment, the resin coating paint of the base color is next prepared (FIG. 1: S105).

Here, the type of the resin coating paint of the base color is not particularly limited, and examples thereof include a curable resin coating paint in which an acrylic resin paint and a curable acrylic resin coating agent are mixed. For example, as shown in FIG. 6B, the operator mixes the base color (for example, white) acrylic resin paint Aa and the transparent curable acrylic resin coating agent Ab at a predetermined mixing ratio to obtain one. A resin-coated paint having a base color is prepared by putting it in a bottle C and stirring it with a stirring rod.

Here, the mixing ratio indicates the ratio between the total volume of the acrylic resin coating material Aa and the total volume of the curable acrylic resin coating agent Ab, and the mixing ratio is not particularly limited, but for example, the resin of the base color. The acrylic resin coating material Aa: 40% by volume to 70% by volume and the curable acrylic resin coating agent Ab: 60% by volume to 30% by volume are preferable with respect to the entire coating coating material, and the acrylic resin coating material Aa: 50. It is more preferably 50% by volume to 60% by volume and 50% to 40% by volume of the curable acrylic resin coating agent Ab: 50% by volume. The type of resin is not particularly limited, and for example, an epoxy resin, a melamine resin, or the like may be used in addition to the acrylic resin.

When the operator completes the preparation of the base color resin coating paint, the base color resin coating paint is then applied to the processing target portion St of the glass bottle 1 that has been sandblasted, and the colored portion Cb is fine. An opaque base color coating layer in which the base color resin coating paint is solidified is formed on the uneven surface (FIG. 1: S106).

Here, the method of applying the base color resin coating paint is not particularly limited, but since the base color resin coating paint is used for the base color, it is necessary to apply it to all of the colored portion Cb. On the other hand, the uncolored portion Ca is protected by the masking film 12. Therefore, it is preferable to apply the base color resin coating paint by spraying the base color resin coating paint onto the portion St to be treated with an airbrush. For example, as shown in FIG. 7A, an airbrush D is prepared, the paint cup Da of the airbrush D is filled with the resin coating paint of the base color, and the nozzle of the airbrush D is provided to the processing target portion St of the glass bottle 1 after the sandblasting treatment. By facing the Dc and operating the main lever Db of the airbrush D, the resin coating paint of the base color is sprayed from the nozzle Dc of the airbrush D onto the processing target portion St of the glass bottle 1. This makes it possible to efficiently apply the base color resin coating paint to the colored portion Cb in a short time.

Here, as shown in FIG. 7B, the operator moves the nozzle Dc of the air brush D little by little in the vertical direction of the glass bottle 1 to evenly scan the glass bottle 1 in the vertical direction with respect to the processing target portion St, or the glass bottle. It is preferable that 1 is rotated little by little in the left-right direction of the glass bottle 1 and the nozzle Dc of the air brush D is evenly scanned in the left-right direction of the glass bottle 1 with respect to the portion St to be processed. As a result, the resin coating paint of the base color can be evenly applied to all of the treated portion St including the colored portion Cb.

Then, the operator leaves the base color resin coating paint for a predetermined time after applying the base color resin coating paint to dry the base color resin coating paint, whereby the base color resin coating paint is solidified and the opaque base color coating layer is solidified. To form.

Here, even if the resin coating paint of the base color is applied once, the coating layer of the base color can be formed on the colored portion Cb, but in the present invention, the resin coating paint of the base color is applied twice or more. Is preferably applied. As a result, the thickness of the coating layer of the base color can be increased to improve the durability, and the base color of the coating layer can be made a vivid color comparable to the ground color of the glass bottle 1.

Here, the application of the resin coating paint of the base color two or more times is not particularly limited, but for example, the resin coating of the base color is applied from the nozzle Dc of the airbrush D as in the case of the first application of the resin coating paint of the base color. This can be done by evenly spraying the paint onto the portion St to be treated.

For example, as shown in FIG. 8A, the operator applies the base color resin coating paint from the nozzle Dc of the airbrush D to the upper and lower parts of the glass bottle 1 with respect to the processing target portion St of the glass bottle 1 after the base color resin coating paint is dried. Spray evenly in the direction and left and right. Then, as shown in FIG. 8B, the operator leaves the resin coating paint of the base color for a predetermined time after the second application of the resin coating paint of the base color to dry the resin coating paint of the base color, and then coats the coating layer of the opaque base color. To form.

Here, as shown in FIG. 8B, it is understood that the base color is very clear in the base color coating layer L1 formed by the second application of the base color resin coating paint. Further, in the portion St to be treated after the application of the resin coating paint of the base color, the coating layer L1 of the base color is formed on the fine uneven surface of the colored portion Cb, so that the coating layer L1 of the base color is fine. It is solidified (hardened) by meshing with the uneven surface. Therefore, the base color coating layer does not peel off even if some force is applied, and the adhesiveness between the base color coating layer L1 and the surface S of the glass bottle 1 can be extremely improved. On the other hand, a coating layer L1 having a base color is also formed on the masking film 12 of the non-colored portion Ca. This is because the masking film 12 is peeled off to form a base color coating layer L1 on the masking film 12. Since the coating layer L1 is also removed, there is no particular problem.

Now, when the operator completes the formation of the coating layer L1 of the base color, next, a resin coating paint of the top coat color of the top coat color is prepared (FIG. 1: S107).

Here, the type of the resin coating paint of the top coat color is not particularly limited, and the curable resin coating paint can be mentioned as described above. For example, as shown in FIG. 9A, a dropper is used to mix a topcoat color (for example, ocher) acrylic resin paint Ac and a transparent curable acrylic resin coating agent Ab in a predetermined mixing ratio. To prepare a resin-coated paint with a top coat color by putting it in a stirring rod and stirring it with a stirring rod. The mixing ratio and the type of resin are the same as described above.

Now, when the worker completes the preparation of the topcoat color resin coating paint, next, a plurality of topcoat color resin coating paints are applied to the base color coating layer L1 of the colored portion Cb of the glass bottle 1 according to the pattern. Separately, an opaque top coat color coating layer in which the top coat color resin coating paint is solidified is formed on the base color coating layer L1 of the colored portion Cb (FIG. 1: S108).

Here, the method of applying the resin coating paint of the top coat color is not particularly limited, but since the resin coating paint of the specific top coat color (of the type of color) is for the top coat, the pattern among the plurality of colored portions Cb It is necessary to separately paint a specific colored portion Cb (corresponding to the top coat color) according to the above. Therefore, regarding the application of the resin coating paint of a specific top coat color, for example, as shown in FIG. 9B, a craft stick E is prepared, and the resin coating paint of a specific top coat color is attached to the tip of the craft stick E to craft. By tracing the coating layer L1 of the base color of the specific colored portion Cb with the tip of the rod E, the resin coating paint of the specific top coat color adhering to the tip of the craft rod E can be applied to the coating layer of the base color of the specific colored portion Cb. It is preferable to apply a resin coating paint having a specific top coat color by placing it on L1. As a result, it is possible to separately apply the resin coating paint of the specific top coat color even in the specific colored portion Cb having a fine grain. The same applies to other topcoat-colored resin-coated paints. Further, by applying the top coat color resin coating paint on the base color coating layer L1, the dried and solidified top coat color coating layer is firmly adhered to the base color coating layer L1. As a result, even if some force is applied to the top coat color coating layer, the durability of the top coat color coating layer can be improved without peeling.

Here, when the top coat color resin coating paint is applied, the glass bottle 1 is cylindrical, and when viewed from the longitudinal direction of the glass bottle 1, it is circular and the surface S is curved. Therefore, when the topcoat color resin coating paint is applied over a wide area at once, the topcoat color resin coating paint flows down along the curvature of the surface S due to gravity, causing unevenness in the topcoat color resin coating paint at the colored portion Cb. There is a possibility that lumps (granular lumps) may occur in the top coat color resin coating paint, and the quality of the top coat color coating layer may deteriorate.

Therefore, in the present invention, as shown in FIG. 10A, the operator prepares a table F for fixing the surface S of the side surface of the glass bottle 1, and of the surface S of the side surface of the glass bottle 1, the portion St to be processed is set. Fix the glass bottle 1 with the base F so that it faces upward. Next, when viewed from the longitudinal direction of the glass bottle 1, the operator puts the colored portion Cb, which has not yet been coated with the resin coating paint of the top coat color, on the processed portion St of the glass bottle 1 on top. A topcoat-colored resin coating paint is applied only to the base-colored coating layer L1 of the colored portion Cb within a predetermined width R1 along the left-right direction (circumferential direction) of the glass bottle 1 centering on the portion Cb, and the topcoat-colored resin is applied. Allow the coating paint to dry. Here, the width R1 is appropriately set according to the shape and size of the glass bottle 1. For example, the width R1 is set to such a width that the topcoat-colored resin coating paint does not drip due to gravity when the topcoat-colored resin coating paint is applied. To.

Then, when the topcoat-colored resin coating paint dries, the operator rotates the glass bottle 1 little by little in the left-right direction of the glass bottle 1 so that the colored portion Cb to which the topcoat-colored resin coating paint has not been applied is facing up. A topcoat-colored resin coating paint is applied only to the base-colored coating layer L1 of the colored portion Cb within a predetermined width R2 along the left-right direction of the glass bottle 1 centering on the colored portion Cb on the top. Allow the coating paint to dry. In this way, the glass bottle 1 is rotated so that the colored portion Cb of the glass bottle 1 in which the topcoat-colored resin coating paint is not applied faces upward, and the coating layer L1 of the base color of the colored portion Cb with a predetermined width R is used. The topcoat color resin coating paint is applied to the topcoat color, and the glass bottle 1 is repeatedly rotated so that the colored portion Cb of the topcoat color resin coating paint is then uncoated. It is possible to apply the resin coating paint evenly and neatly.

Here, regarding the application of the topcoat-colored resin coating paint to the recess formed by the colored portion Cb of the treated portion St, for example, as shown in FIG. 10B, the coating layer L1 of the base color of the colored portion Cb is uncolored. It is preferable that a predetermined amount of the masking film 12 of the partial Ca and the coating layer L1 of the base color on the masking film 12 are applied with the resin coating paint of the top coat color. As a result, the topcoat-colored resin coating paint is applied so as to protrude from the wall surface of the periphery of the base color coating layer L1 of the colored portion Cb to the masking film 12 of the uncolored portion Ca and the base color coating layer L1 above it. Then, as will be described later, when the masking film 12 of the uncolored portion Ca and the coating layer L1 of the base color on the masking film 12 are peeled off, the coating layer L2 of the topcoat color solidified to the masking film 12 is peeled off, but the topcoat color Since the coating layer L2 covers from the peripheral wall surface to the inside of the coating layer L1 of the base color of the colored portion Cb, the coating layer L1 of the base color does not appear at the boundary between the colored portion Cb and the uncolored portion Ca, and the top coat The color finish can be improved.

Further, depending on the configuration and type of the pattern, if it is desired to apply the topcoat-colored resin coating paint to the convex portion composed of the uncolored portion Ca of the portion to be processed St, it is necessary to devise a method. In S104, after sandblasting once to form a fine uneven surface on the colored portion Cb, the masking film 12 of the uncolored portion Ca was peeled off and the masking film 12 was peeled off as shown in FIG. 11A. By lightly sandblasting the uncolored portion Ca, the uncolored portion Ca is used as the semi-colored portion Ca1 to form a fine uneven surface. Then, in S105 and S106, the base color resin coating paint is applied to the fine uneven surfaces of the colored portion Cb and the semi-colored portion Ca1, and in S107 and S108, the top coat color resin coating paint is applied to the semi-colored portion Ca1. .. As a result, it is possible to form the base color coating layer L1 on the fine uneven portion and to form the top coat color coating layer L2 on the convex portion composed of the semi-colored portion Ca1. Even if some force is applied to the topcoat-colored coating layer L2 of the semi-colored portion Ca1, the durability of the topcoat-colored coating layer can be improved without peeling.

Here, if the semi-colored portion Ca1 in which the masking film 12 is simply peeled off is directly coated with the topcoat-colored resin coating paint without sandblasting, the fine uneven surface that enhances the adhesiveness is semi-colored. Since it does not exist in the partial Ca1, the coating layer L2 having the topcoat color after drying is easily peeled off from the semi-colored portion Ca1 and cannot be commercialized.

Now, when the worker completes the application of the resin coating paint of the top coat color, and it is necessary to apply the colored portion Cb with another top coat color (of a different color) (Fig. 1: S109YES), the worker is asked. Returning to S107, another topcoat color resin coating paint is prepared (FIG. 1: S107), and in S108, another topcoat color resin coating paint is applied (FIG. 1: S108).

For example, as shown in FIG. 11B, the operator uses the craft rod E to specify a resin coating paint of a specific other top coat color (for example, a light orange color) according to the pattern in the same manner as described above. The other topcoat color is obtained by applying it to the base color coating layer L1 of the colored portion Cb, leaving it for a predetermined time after applying the other topcoat color resin coating paint, and drying the other topcoat color resin coating paint. The resin coating paint of No. 1 forms a coating layer of another top coat color solidified. In this way, full-color coloring can be realized by separately applying various (types) of topcoat-colored resin coating paints to the plurality of colored portions Cb according to the pattern. Depending on the type of pattern, there may be a colored portion Cb in which only the coating layer L1 of the base color of the base color is not applied with the resin coating paint of the top coat color.

When the operator repeats S107 and S108 to complete the application of the plurality of topcoat-colored resin-coated paints on the colored portion Cb (FIG. 1: S109NO), the entire masking members Ma and Mb of the glass bottle 1 are peeled off. At the same time, the masking film 12 (and the base color coating layer L1 on the uncolored portion Ca) of the glass bottle 1 is peeled off.

The peeling of the masking members Ma, Mb and the masking film 12 is not particularly limited. For example, as shown in FIG. 12A, the operator peels off the masking members Ma and Mb that mask the entire glass bottle 1 to expose the surface S of the glass bottle 1 hidden around the processing target portion St. Next, as shown in FIG. 12B, the operator uses a peeling means G such as a spatula to peel off the masking film 12 of the uncolored portion Ca around the treatment target portion St. By peeling the masking film 12, the coating layer L1 of the base color on the masking film 12 is naturally removed.

Further, as shown in FIG. 13A, the operator uses the peeling means G to peel off the masking film 12 of the uncolored portion Ca in the center of the treatment target portion St. As a result, the surface S of the glass bottle 1 is exposed to the uncolored portion Ca.

Then, when the operator completes the peeling of all the masking films 12, the processing target portion St is washed with water to remove the masking film 12 and the like that have failed to be peeled off (FIG. 1: S110).

The method of washing the treatment target portion St with water is not particularly limited. For example, the sponge I is wetted with water and the sponge I is rubbed against the treatment target portion St to remove the remaining masking film 12 and the like. Further, after washing with water, the operator completes the full-color coloring of the glass bottle 1 by wiping off the water remaining on the treatment target portion St using a wiping means J such as a towel.

Here, even if the portion St to be treated is washed with water, the base color coating layer L1 and the top coat color coating layer L2 do not peel off. This is because the base color coating layer L1 enhances the adhesion to the fine uneven surface, and the top coat color coating layer L2 enhances the adhesion to the fine uneven surface via the base color coating layer L1. Therefore, even if some force such as washing with water is applied to the base color coating layer L1 and the top coat color coating layer L2, both are not peeled off. In this way, the durability of the glass bottle 1 against full-color coloring is enhanced.

Now, the remarkable effect of the present invention will be described. FIG. 14 shows a photograph of a one-color colored glass bottle 2 corresponding to the prior art and a full-color colored glass bottle 1 manufactured by the present invention side by side. As shown in FIG. 14, the one-color colored glass bottle 2 of the prior art has a single color, and due to the presence of the ground color of the glass bottle, the color is defeated by the ground color of the glass bottle even though it is an opaque coating layer. It is understood that it looks blurry. On the other hand, in the full-color colored glass bottle 1 of the present invention, since the opaque topcoat color coating layer L2 is provided on the opaque base color coating layer L1, the topcoat color does not lose to the ground color of the glass bottle. It is understood that it appears vividly.

Further, when the ground color of the glass bottle 1 appears in the line portion of the uncolored portion Ca and the top coat color (or the top coat color resin coating paint) of the top coat color coating layer L2 is not applied to the closed region portion of the colored portion Cb, It is understood that the difference between the ground color of the glass bottle 1 and the top coat color (or the base color) is emphasized because the base color of the coating layer L1 of the base color appears, and the pattern appears extremely vividly and emerges. To. The color is as if a label had been attached to the glass bottle 1. Moreover, it is durable without being eroded by water or the like. The unevenness of the uncolored portion Ca and the colored portion Cb makes the pattern a three-dimensional decoration, increasing the decorativeness and artistry of the glass bottle 1.

As described above, the full-color colored glass bottle 1 manufactured by the present invention has a pattern provided on a specific portion (processed portion St) of the surface S of the glass bottle 1 and a line portion (non-standard) constituting the line of the pattern. Corresponding to the colored portion Ca), the height is equivalent to the surface S of the glass bottle 1, and the convex portion having the same ground color as the surface S of the glass bottle 1 and the closed region portion (colored portion Cb) are corresponding to the glass bottle 1. Above the concave portion formed deeper than the surface of the above and having a fine uneven surface, the opaque base color coating layer L1 formed on the fine uneven surface of the concave portion, and the base color coating layer L1. In addition, a plurality of opaque top coat color coating layers L2, which are formed by being painted separately according to the pattern, are provided. The full-color colored glass bottle having such a configuration has durability, realizes vivid full-color coloring, and enhances the decorativeness and artistry of the glass bottle 1. As described above, it is clear that the configuration of the masking seal 10 has the same effect even if the convex portion becomes a closed region portion and the concave portion becomes a line portion.

As described above, in the present invention, it is possible to realize durable and vivid full-color coloring, and to enhance the decorativeness and artistry of the glass bottle 1.

As described above, the full-color coloring method for glass bottles and the full-color colored glass bottles according to the present invention are useful for various glass bottles, have durability, realize vivid full-color coloring, and are decorative to the glass bottle 1. It is effective as a full-color coloring method for glass bottles and a full-color colored glass bottle that can enhance artistry.
