The present invention relates to a porcelain stopper and a manufacturing method thereof, and more particularly, to a porcelain stopper configured to be opened and closed by a screw coupling formed in the inlet of the porcelain container and a method of manufacturing the same.

In general, porcelain containers, such as porcelain bottles used for storing alcohol, other beverages, food, etc., are formed in a shape in which the inlet is opened in a circular shape during the manufacturing process. In order to seal the inlet of the porcelain container, a method of injecting a cork stopper or combining a stopper made of plastic is mainly used.

The conventional method of press-fitting the cork stopper is not easy to open and close, there is a possibility that the contents are leaked because the complete closure is not made when repeatedly closed.

In addition, the method of joining the stopper made of plastic may provide a high-quality appearance by making the container body made of porcelain, but there is a fear that the stopper may be heterogeneous by making the stopper made of plastic and damage the luxury of the overall appearance. There is a risk of making.

Therefore, it is very advantageous in terms of ease of opening and closing, sealing, unity of appearance and luxury, such that the male screw is formed at the entrance of the ceramic container and the ceramic stopper can be screwed together.

However, it is known that it is difficult to form a female screw on the inner peripheral surface of a stopper shape due to the manufacturing characteristics of ceramics, and a method for realizing this has not been proposed.

For example, as a method of manufacturing ceramic containers in large quantities, molds made of gypsum having excellent hygroscopicity are mainly used. In this case, soil water is injected into a plaster mold having a cavity formed along the outer surface, and the soil water is absorbed by the hygroscopic action of the plaster. It manufactures by determining the thickness of a container using drying. Therefore, when manufacturing a ceramic using a gypsum mold, it is possible to form the external appearance of the ceramic in various shapes, it is impossible to form a separate shape different from the external shape on the inner surface.

The present invention has been made in view of the above points, since the internal thread of the shape corresponding to the male screw formed at the inlet of the ceramic container can be formed on the inner side, the opening and closing can be easily and repeatedly made, and the appearance is made in a clean and refined form. To provide a porcelain stopper, for that purpose.

Another object of the present invention is to provide a method of manufacturing a porcelain stopper capable of forming a female screw on the porcelain stopper by coupling the female screw forming member of an elastic material to the core for forming the porcelain stopper.

Next, a preferred embodiment of a method of manufacturing a ceramic stopper according to the present invention will be described.

First, a process of manufacturing the ceramic container 10 by a widely used slip casting method will be described.

In order to manufacture the porcelain container 10, as shown in Figures 4 to 5, the gypsum mold 11 and the gypsum mold 11, which is bisected to the left and right and made the same as the outer appearance of the porcelain container 10, Funnel gypsum mold (12) coupled to the top of the funnel gypsum mold (12) having a funnel gypsum mold (12) formed with a funnel-shaped inlet (14) is assembled on top 12) to the bottom of the screw pipe 13 to form a male screw is coupled.

Filling the soil (slip) in the plaster mold 11 with the inlet 14 and a predetermined time passes, the ceramic container 10 is formed to a predetermined thickness inside the plaster mold 11, the porcelain When the thickness of the container 10 is formed to a desired thickness, the entire mold is turned upside down, and the plaster mold 11 is filled with discharged water, and after a predetermined time, the funnel plaster mold 12 and the plaster mold 11 are discharged. The porcelain container 10 which can be used by baking the porcelain container 10 by removing it is manufactured.

When the ceramic container 10 is formed as described above, the ceramic pipe 10 is molded in a form in which the screw pipe 13 is inserted into the entrance of the ceramic container 10.

The porcelain container 10 is subjected to a drying and firing process, it is also possible to configure so that the screw pipe 13 is incinerated by heat during firing.

The screw pipe 13 may be made of rubber or synthetic resin having elasticity. In this case, the screw pipe 13 can be easily separated from the ceramic container 10 in which the solidification molding is completed.

Through such a process, the ceramic container 10 in which male threads are formed at the inlet is formed.

In the above, one embodiment of manufacturing the ceramic container 10 is described as an example, and a method of manufacturing the ceramic container 10 with various structures is used, and all of these methods are applicable to the present invention.

And one embodiment of the porcelain stopper manufacturing method according to the present invention, as shown in Figure 6 to 8, forms a cavity 32 for forming the outer surface of the porcelain stopper 20 therein and the cavity 32 on one side Upper mold 30 to form the injection hole 34 so as to penetrate through) and the lower mold 40 to form the core 42 inserted into the cavity 32 to form the inner surface of the porcelain stopper 20 To prepare (P10), the core 42 is a male screw shape is formed to form a female screw on the inner surface of the porcelain stopper 20, and combines the female screw forming member 50 made of an elastic material (P20), the core 42 The lower mold 40 and the upper mold 30 coupled to the female screw forming member 50 are assembled and assembled (P30), and formed through the injection hole 34 in the inner cavity 32 of the upper mold 30. Filling the material 60 (P40), the upper mold 30 and the lower mold 40 is assembled for a predetermined time in a state Solidification molding is performed (P50), and the lower mold 40 is separated from the upper mold 30 in a state where the molded article and the female thread forming member 50 are coupled (P60), and the molded article and the female thread forming member from the upper mold 30. Each of the (50) is separated (P70), the molded product is made of a process (P80) of the plastic working.

The upper mold 30 and the lower mold 40 are preferably made of a porous gypsum material to smoothly absorb the moisture of the injected molding material 60.

The molding material 60 is used in the slip casting method (slip casting) used to make the ceramics, the soil (slip) by mixing clay and water and peptizing agent in a certain ratio Are manufactured. Since the soil is generally implemented by applying soil water used in the manufacture of ceramics, detailed description thereof will be omitted.

The injection hole 34 formed in the upper mold 30 has a hole formed through the cavity 32 so that the molding material 60 gradually enters the cavity 32 and is formed outside the upper mold 30. The hole is formed in a funnel shape with a large cross section.

Holes formed on the outside of the upper mold 30 is preferably formed in the upper surface in order to flow smoothly into the cavity (32).

The core 42 is formed to protrude in a cylindrical shape from the center of the lower die 40.

The female screw forming member 50 is formed in a size range that can be smoothly fitted to the outside of the inlet portion of the ceramic container, the material may be used, such as rubber or synthetic resin, silicone having elasticity.

A female screw forming member 50 is inserted into the core 42.

The female screw forming member 50 extends to the vertical portion 52 and the vertical portion 52 surrounding the core 42 so as to be inserted into the core 42 and the center portion of the lower die 40 while being inserted. It consists of a horizontal portion 54 that extends to the upper portion of the lower die 40.

On the outer circumferential surface of the vertical portion 52 of the female screw forming member 50, a male screw (a male screw having a shape corresponding to the male screw formed at the inlet of the ceramic container 10) is formed to form the female screw.

6, grooves having a shape corresponding to the shape of the horizontal portion 54 are formed in the upper portion of the lower die 40.

The horizontal portion 54 is formed wider than the maximum diameter of the cavity 32 formed in the upper mold 30 when the upper mold 30 and the lower mold 40 are assembled and assembled.

When formed as described above, when the molding material 60 is injected in the state in which the upper mold 30 and the lower mold 40 are assembled and assembled, the female thread forming member is formed at a portion at which an edge of the main body 22 is formed. Since the solidification molding is performed in a state where the molding material 60 is not in contact with the lower mold 40 when the lower mold 40 is positioned, it is possible to smoothly form an edge portion of the main body 22 toward the ceramic container 10.

At least one of the upper mold 30 and the lower mold 40 is formed at a portion where the upper mold 30 and the lower mold 40 contact each other, and at least one protrusion 36 is formed on the other side of the mold. Grooves 44 are formed to correspond to 36.

When the protrusions 36 and the grooves 44 corresponding to the protrusions 36 are formed as described above, since the positions of the upper mold 30 and the lower mold 40 are integrated with each other without a gap, the shape of the main body 22 is different. It is possible to prevent this phenomenon of warping and twisting, and variations in thickness due to the deflection to one side.

The protrusion 36 is formed of a round curved surface or a smooth curved surface so as not to be easily damaged or damaged by external force due to the characteristics of gypsum, which is a material forming the upper mold 30 and the lower mold 40. It is preferable.

Since the sealing member 26 is formed on the inner horizontal surface of the main body 22, airtightness is maintained between the porcelain container 10 and the porcelain stopper 20, and the sealing property can be remarkably improved. There is an advantage.

In the above, the lower mold 40 is separated from the upper mold 30, and then the molded article and the female thread forming member 50 are separated from the upper mold 30, respectively. It is also possible to separate the female thread forming member 50 and to take out the molded product from the upper mold 30 after separating 40), and to separate the lower mold 40 from the upper mold 30 and then to the upper mold 30. It is also possible to take out the molded article and separate the female screw forming member 50 from the molded article.

In the plastic working step (P80) of the molded product, it is preferable to fire the ceramic container 10 and the ceramic stopper 20 together in the same kiln.

When the porcelain container 10 and the porcelain stopper 20 are separately charged into the kiln at different times and fired, the firing conditions such as the temperature of the kiln and the timing of taking out the fired molded products even when the same kiln is used. Due to this, there is a possibility that the deviation of the dimension between the porcelain container 10 and the porcelain stopper 20 large after the firing is completed, there is a possibility that the assembly error occurs.

At this time, when assembling the porcelain stopper 20 in the porcelain container 10 is not completely sealed, so that the preservation of the contents of the porcelain container 10 is lowered, as a result of the appearance of the porcelain container 10 and the porcelain stopper 20 Due to the inconsistency, the aesthetics will fall, and the porcelain stopper 20 may not be assembled to the porcelain container 10.

Therefore, the pottery container 10 and the pottery stopper 20 are charged together at the same time in the same kiln so as to be fired under the same firing conditions, and the firing is performed between the pottery container 10 and the porcelain stopper 20. Since the dimensional deviation is minimized and the assembly error can be minimized, the integrity of the contents is not only increased, but also the porcelain container 10 and the porcelain stopper 20 are assembled with almost no gaps, so that they are seen as one with each other, resulting in an overall aesthetic sense. This improved effect is obtained.

In addition, another embodiment of the method of manufacturing the porcelain stopper according to the present invention can also be configured to arrange a plurality of porcelain stopper horizontally and vertically in a row to manufacture a large amount simultaneously.

For example, the mold 100 may be formed of an upper mold 30a and a lower mold 40a, and the mold 100 may be formed by arranging cavities in two rows by four rows, and three rows by three rows. It is also possible to form a cavity by arranging, it can be configured in a variety of arrangements depending on the number of porcelain stopper 20 produced.

The lower die 40a is formed with a plurality of cores 42 corresponding to the number of cavities 32 arranged in the upper die 30a, and each of the cores 42 has a female thread forming member 50. Is inserted.

It is also possible to form an injection hole 34 on one side so that the molding material 60 can be filled in the upper mold 30a, and an injection hole 34 is formed on one side of the lower mold 40a. It is also possible.

In addition, when the molding material 60 is injected into the upper mold 30a through the injection hole 34, the gate 32 may be formed so that the molding material 60 may be filled in the cavity 44. In addition, it is also possible to form the gate 44 in the lower die 40a.

As shown in FIG. 8, the gate 44 forms a flow path radially from the injection hole 34 such that the molding material 60 is injected into the plurality of cavities 32.

When the mold 100 is configured as described above, it is possible to form a large number of porcelain stoppers 20 at once.
