PROBLEM TO BE SOLVED: To prevent a sealing strength of a glass bottle from being decreased, reduce a disturbance in the sealing strength and improve both a sealing characteristic and easiness in seal opening operation. SOLUTION: A top surface of a port of a glass bottle is applied with a processing of ionized gas and/or a processing by dried gas, thereby moisture, organic materials and carbonate produced under weathering adhered to the top surface of the port of the glass bottle are removed before sealing the glass bottle, resulting in that both sealing characteristic and easy seal opening characteristic are improved. |
