The present invention relates to a pottery container manufacturing apparatus which can manufacture a container for a pottery container and a lid body separately and then adhere to each other to provide an excellent esthetic feeling and improve the quality of a product as compared with other containers made of plastic or the like.

Generally, a pottery container is generally used for storing contents such as food, cosmetics and the like, and thus has a concave portion corresponding to the plug at the entrance of the container. Most of these recesses and protrusions are formed in the form of threads on the outer peripheral surface of the container inlet, and are screwed in accordance with the rotation of the stopper.

Conventional ceramics containers are usually molded using a mold made of gypsum in order to mass-produce them, and a slip is injected into a gypsum mold to dry the slip by the hygroscopic action of the gypsum, Lt; / RTI >

However, the porcelain container manufactured in this manner is difficult to form a fine portion such as a thread and has a defect that the fine portion during use is worn or crushed because its thickness is not constant even after it is made.

Therefore, in order to compensate for such defects, a method has been proposed in which a threaded plastic concavo-convex portion is provided on the outer periphery of the inlet of the container instead of forming a screw thread directly around the container.

However, forming a part of the pottery container with plastic may dilute the unique characteristics of the product possessed by the pottery container, thereby deteriorating the value of the product.
