Description

METHOD FOR FORMING PROTRUSION OF GLASS CONTAINER

Technical Field

The present invention relates to a method for forming a protrusion

having a sanding surface of a glass container, and in particular to a method for

forming a protrusion having a sanding surface capable of forming a protrusion

having a sanding surface by sanding the whole surfaces including inner and

outer surfaces of a glass container and coating an acid-proof ink on a certain

portion of a glass container.

Background Art

A glass container is a life item such as a food container, a water cup, a

wine cup, a crystal product, etc. and is fabricated using a mold or a blowpipe. In

order to provide a certain decoration, a fabricated glass container is further

processed for thereby fabricating various decoration products.

The methods for further processing a first fabricated glass container or

providing various decorations will be described. There is a cutting process of a

crystal container as a representative method related to the present invention. In

the crystal cutting method, an outer surface of a first fabricated crystal container

is cut by rotating a wheel having a diamond at a high speed and has a straight

line shape or a curved line shape for thereby achieving a certain combination of straight and curved lines. In this case, it is possible to express a certain image

using various sizes of wheels.

In addition, in order to achieve a popularity and low cost, there are

many products mass-produced using a mold instead of using a cutting method.

However, a high cost is needed for a mold fabrication, and it takes a long time.

It is impossible to fabricate a precise product. In this case, the mass production

is possible but a consumer cannot select a desired product among many

products. As the prices of the products are gradually decreased due to a high

competition, a company profit may be decreased.

In the case of the method for directly cutting the outer surfaces of the

products using a diamond wheel, the cut surfaces are changed to non-

transparent surfaces. Therefore, the cut surfaces are soaked in a fluorine acid

mixture aqueous solution combined with fluorine acid and lactic acid at a certain

ratio for thereby making the non-transparent surfaces transparent. In order to

form a certain image is formed, the surfaces corresponding to the image are not

acid-processed. The above method is one of the image expression techniques

implemented based on a difference comparison between the transparency and

non-transparency. Namely, the image is inverted based on whether the

transparent portion is mainly considered or the non-transparent portion is mainly

considered. Therefore, the crystal cutting is an important process for achieving

a desired decoration. When a certain surface is processed and has a transparent surface, light is reflected or refracted by the cut surfaces for thereby

forming a random reflection like a crystal.

However, in the crystal cutting method, there is a limit in expression due

to a structural characteristic of a diamond wheel, and it is impossible to cut a

precise image. Therefore, there is a problem for expressing a certain image

intended to transfer a certain subject. In addition, in the above method, it is

possible to form protrusions based on an engraving method on the surfaces of

the glass, but an embossing method capable of protruding the surfaces of the

glass having a certain height cannot be implemented.

Disclosure of Invention

Accordingly, it is an object of the present invention to provide a method

for forming a protrusion having a sanding surface of a glass container that

overcomes the problems encountered in the conventional art.

It is another object of the present invention to provide a method for

forming a protrusion having a sanding surface of a glass container in which a

protrusion having a sanding surface is formed at a certain portion of a container

surface in such a manner that the whole surfaces of a glass container including

inner and outer surfaces are sanded, and a certain character or image is coated

on a certain portion of the glass container by a silk printing method using an

anti-acid ink, so that a user can feel protrusions when using the glass container. The formed images are clearly seen based on a good contrast between the

transparent and non-transparent surfaces. Various images can be easily formed

through a silk printing method. A mass production is possible. The protrusions

may be formed in the inner surfaces of the glass container by a pad printing

method.

In order to achieve the above objects, there is provided a method for

forming a protrusion having a sanding surface of a glass container that is a

generally used life item, comprising the steps of a step for sanding the whole

surfaces including inner and outer surfaces of a glass container; a step for

forming a filled anti-acid ink coating part at a portion of the inner and outer

sanding surfaces, said anti-acid ink coating part having the same shape as a

character or an image that is to be expressed; a step for soaking the glass

container in a fluorine acid mixture aqueous solution during a certain time

period for thereby performing an acid process and making the portions

transparent except for the anti-acid ink coating portion; and a step for rinsing the

anti-acid ink coating portion coated on the sanding surface of the glass

container using a sodium hydroxide.

Best Mode for Carrying Out the Invention

The preferred embodiments of the present invention will be described

with reference to the accompanying drawings.

Figure 1 is a front view of a sanding process for sanding the whole inner

and outer surfaces of the glass container 1 using a sandblaster. In the present

invention, the sandblaster is capable of sanding the whole surfaces of the glass

container 1 during a very short time period in such a manner that diamond

sands 15 are discharged through a discharging nozzle at an air pressure of

1~5kg/cm². After the sanding process is finished, the sanding surfaces 11 are

formed in the whole surfaces of the glass container 1. When the sanding surfaces 11 are fabricated, the outer sanding surfaces

11 of the glass container 1 are coated with the anti-acid ink 26 through the

opened meshes 23 of the net silk 22 as shown in Figure 2A for thereby

expressing a desired character or image or the inner surfaces of the glass

container 1 may be coated using a brush painting or a pad printing method.

Figure 2B is a cross sectional view when the coating of the anti-acid ink 26 is

finished, and Figure 3 is a front view when the coating of the anti-acid ink 26 is

finished.

After the coating of the anti-acid ink 26 is completed with respect to the

sanding surface 11 , the sanding surface is soaked in the fluorine acid aqueous

solution 40 combined with a fluorine acid and lactic acid at a certain ratio for

thereby performing a transparent process. As shown in Figure 4A, a swing net

42 formed of an anti-acid material and having the glass container 1 is soaked in

the container 45 having the fluorine acid aqueous solution 40 and is swung

uniformly. Otherwise, the chemical agent may etch the surfaces of the glass

container 1 for thereby forming randomly dented surfaces. At this time, the

soaking time should be constant. If the soaking time is over passed, as shown

in Figure 4B, the height of the protrusion 50 may be high but the width of the

sanding surface 11 may be decreased, so that it is impossible to obtain a

desired effect.

Therefore, when designing a desired character or image, the above matters should be considered. The dimensions of the character or image to be

expressed are increased, and the time of the soaking is expressed in data.

Thereafter, the acid process is performed. The area of the sanding surface 11

after the acid process should be maintained as original area.

Thereafter, the glass container 1 is soaked in the sodium hydroxide

aqueous solution that is alkali, and the anti-acid ion 26 is rinsed for thereby

fabricating a finished product as shown in Figure 5.

As described above, in the present invention, the protrusion having a

sanding surface is formed using an anti-acid ink after the whole surfaces of the

glass container are sanded. The user can feel the protrusions with hands. The

contrast between the transparent glass surfaces and the sanding surface of a

certain portion is clear, and the protrusion may be seen from in the lateral

direction. Various images may be easily formed. A desired image may be

expressed. Multiple kinds and mass products are implemented. It is possible to

form the protrusions having the same sanding surface as the outer surface even

in the inner surface of the glass container. A high quality glass container may be

fabricated.

As the present invention may be embodied in several forms without

departing from the spirit or essential characteristics thereof, it should also be

understood that the above-described examples are not limited by any of the

details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the

appended claims, and therefore all changes and modifications that fall within

the meets and bounds of the claims, or equivalences of such meets and bounds

are therefore intended to be embraced by the appended claims.
