本発明は湯呑み、茶椀等に使われる二重陶磁器
及びその製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a double-sided ceramic used for teacups, tea bowls, etc., and a method for manufacturing the same.
従来の二重陶磁器の製造方法における鋳込成形

た。
The conventional casting method used to manufacture double-sided ceramics uses a molding material called plastic slurry, which is made by mixing crushed porcelain clay or clay with water, or a mixture of water glass and soda carbonate instead of water. The molding material made into a slurry using a deflocculant is poured into a mold made of a plaster mold, etc., and left to stand for a while. When a thin layer of base material forms on the inner surface of the mold, the molding material slurry remaining inside is discharged. However, the molded product was removed from the mold once the base material became hard.
そして、上記した製造方法による成形物には、
第３図に示すように成形上、成形材料泥漿を排出

樹脂製の底栓２を用いて底穴１を封止しており、
前記底栓２に接着剤３を塗布して底穴に嵌合させ
ることにより接着固定されているのであつた。 The molded product manufactured by the above-mentioned manufacturing method includes:
As shown in Figure 3, during molding, there remains a bottom hole 1 with a diameter of 2 to 8 m/m for discharging the molding material slurry, so water does not enter the hollow part of the double ceramic from this bottom hole 1. In order to improve the appearance, the bottom hole 1 is sealed using a synthetic resin bottom plug 2.
Adhesive 3 was applied to the bottom plug 2 and the bottom plug 2 was fitted into the bottom hole to be adhesively fixed.
この場合、第４図に示すように底穴１の周囲及
び内面と底栓２の双方に接着剤３を塗布してから
底栓２を底欠１に嵌合させる手段をとつている。 In this case, as shown in FIG. 4, the adhesive 3 is applied to both the periphery and inner surface of the bottom hole 1 and the bottom plug 2, and then the bottom plug 2 is fitted into the bottom notch 1.

However, since double-walled ceramics undergo complicated manufacturing processes such as firing, the diameter of the bottom hole 1 varies widely, and the bottom plug 2 that fits into the bottom hole 1 basically has a diameter of the fitting part. Since the bottom hole 1 and the bottom plug 2 are molded to a predetermined size that is less than the diameter of the bottom hole, there is a drawback that backlash occurs between the bottom hole 1 and the bottom plug 2. For this reason, adhesive 3
Until the adhesive hardens, if there is an increase in internal pressure, bubbles that tend to occur in the adhesive, pinholes or lifting of the bottom plug may occur, or the gap between the bottom plug and the bottom hole may increase. Due to variations in the amount of adhesive, pinholes may occur, adhesive may protrude, areas 4 may not reach the adhesive 3, and the bottom plug and container may be made of different materials, resulting in poor binding. This resulted in a decrease in work efficiency and an increase in the product defect rate.
