解決が望まれていた。(C) Problems to be Solved by the Invention In recent years, a new bottle mouth sealing method has emerged in order to change the specifications of glass containers and reduce costs.

In this case, metal oxide (SnO 2 , TiO 2 etc.)
It has been found that the adhesion strength can be further improved by forming a film of the above. However, in the conventional method, if a metal oxide film is to be formed on the top surface of the wide-mouthed glass container, it is inevitable that a processing medium enters the inner surface, and a solution to this point has been desired.
