The present invention's medium for combination may take place by using other mediums besides the aforementioned combination pipe (12) or combination projection (13), but these shall include a structure whereby screw pipe (14) can be attached.
The present invention's screw pipe (14) is made with materials such as plastic, resin and starch that can be destroyed by fire when heat is exerted. Screw pipe (14) shall be destroyed by fire during the process of incineration for ceramic bottle (1).
The following is the production method for the ceramic bottle (1) of the present invention.
First of all, the process of assembling plaster framework (2) (3) is comparable to that of existing slip casting. In the present invention, medium for combination is installed at the lower part of the funnel-shaped plaster framework (5) to combine with screw pipe (14).
When combination pipe (12) is formed at the lower part of the funnel-shaped plaster framework (5), combine by circulating with screw pipe (14) attached on. When combination projection (13) is formed at the lower part of the funnel-shaped plaster framework (5), then combine by circulating after inserting into the combination groove (18) of the screw pipe (14).
When screw pipe (14) is combined with the lower part of the funnel-shaped plaster framework (5) using medium for combination, install funnel-shaped plaster framework (5) in a way so that the aforementioned screw pipe (14) is situated at the inside of plaster framework (2) (3). Then, insert slip into the inner part of the plaster framework (2) (3) through the main entrance (4) of the aforementioned funnel-shaped plaster framework (5).
When slip is filled inside the plaster framework (2) (3) and funnel-shaped plaster framework (5), then ceramic bottle (1) of specific thickness shall be formed after specific time lapses by. When the time needed for the formation of desired ceramic bottle (1)'s thickness at the interior of the plaster framework (2) (3) lapses by, discharge slip, filled in the plaster framework (2) (3) by lifting plaster framework (2) (3) up side down.
When the slip, filled in the plaster framework (2) (3), is discharged, then return plaster framework (2) (3) into its original position. Then, remove funnel-shaped plaster framework (5)'s medium for combination to separate screw pipe (14), and lift out funnel-shaped plaster framework (5) to separate into plaster framework (2) (3) again.
Then, ceramic bottle (1) is formed at a state whereby screw pipe (14) is inserted into the entrance (6), which leads to the birth of complete ceramic bottle (1) after going through the drying and plasticity processes.
Plasticity process is undergone at a state whereby screw pipe (14) is inserted into the entrance (6) of aforementioned ceramic bottle so that screw pipe (14) maybe completed destroyed by fire during the above mentioned process due to heat.
Then, screw-like projection (11) is formed at the entrance (6) of ceramic bottle (1), which coincides with the external view of the screw pipe (14), and which in turn is produced at a specific, consistent measurement since screw pipe (14) is produced in a consistent manner.
When the ceramic bottle (1), formed with screw-like projection (11) at the entrance (6), completed, the screw-like projection (15) is formed on the plastic cork (16) to ensure combination among screw-like projections (11) (15). Therefore, entrance (6) of ceramic bottle (1) is blocked with plastic cork (16).
Here, air-tightening of ceramic bottle (1) with plastic cork (16) is made impeccable. However, when doubtful, use silicon packing (17) to air-tight with plastic cork (16) from the upper part of the ceramic bottle (1) to ensure a more complete air-tightening. As mentioned above, the ability to tighten the entrance (6) of ceramic bottle (1) by using plastic cork (16) in a form of screwing in by forming screw-like projection (11) is not limited to the ceramic bottle (1). Application can be made on the ceramic container with wide entrance and other products such as ceramic container and related products.
