Patent ID: 7276202

Claim:
A method of manufacturing a ceramic bottle sealed by a plastic cork, the ceramic bottle manufacturing method comprising the steps of: combining a screw pipe ( 14 ) with a combining medium formed at the lower part of a main entrance ( 4 ) of a funnel-shaped plaster framework ( 5 ); placing the funnel-shaped plaster framework ( 5 ) combined with the screw pipe ( 14 ), onto the upper part of plaster frameworks ( 2 )( 3 ), and then injecting slip into the frameworks ( 5 )( 2 )( 3 ); pouring the slip after the thickness of the ceramic bottle ( 1 ) has been formed between the plaster frameworks ( 2 )( 3 ) and the screw pipe ( 14 ); separating the funnel shaped plaster frameworks ( 5 ) from the plaster frameworks ( 2 ) ( 3 ) and then maintaining the screw pipe ( 14 ) at the state where the screw pipe has been combined with the entrance ( 6 ) of the ceramic bottle ( 1 ); and undergoing a plasticity process for the ceramic bottle ( 1 ) at the state where the screw pipe ( 14 ) has been combined with the entrance ( 6 ) of the ceramic bottle ( 1 ), thereby incinerating the screw pipe ( 14 ) and forming a screw injection ( 11 ) on the inner side of the entrance ( 6 ) of the ceramic bottle ( 1 ), so that the plastic cork having a screw portion can be engaged with the screw projection ( 11 ); wherein the combining medium comprises a combination pipe ( 12 ) or a combination projection ( 13 ) that is combined with and separated from the screw pipe ( 14 ).
