| 摘要 |
The present invention relates to a liquid leakage prevention structure of a piston-lowering type dispenser vessel, which provides, on the top surface of a base, a sealing member to come into contact with the lower end part of a vessel main body, thereby preventing the liquid leakage of contents through a space between the lower part of the vessel main body and the base when the piston moves in the downward direction. |
