WINE STOPPER

The present invention relates to a wine stopper which comprises: a main body which has a circular cone shape whose diameter becomes narrower in a downward direction; a projection unit extended in the downward direction in the same shape as the main body in a state of protruding from the bottom of the main body in the diameter direction; a sealing member inserted into the outer circumferential surface of the main body in the corresponding shape and then has elasticity to maintain the outer circumference thereof in order to agree with the outer circumference of the projection unit; and a circular ring formed on the top of the main body. Therefore, the wine stopper can improve the style of the appearance thereof by making the stopper beautiful; can maintain the flavor and smell through the prevention of oxidation by providing close and complete sealing power during re-sealing; and can easily, rapidly, and conveniently be opened without applying a large force during re-opening.
