ABSTRACT:
A bottle stopper mainly includes a body, a plug and a jacket. The body has an expansion spread by the plug and outwardly confronting with the jacket. The plug comprises two necks for two different engagements alternatively engaged with the body to provide a locking means and a resealing means for bottle neck. The body is structurally retained between the plug and the jacket being assembled as a unit to form the bottle stopper. When the bottle stopper is initially inserted into a bottle neck and pressed to position at the first engagement, the locking means provides a maximum expansion to lock around the bottle neck. And it has an appearance and a function of indicating whether the bottle neck has previously opened or the stopper has been used. When the bottle stopper is pressed downward positioning at the second engagement, the resealing means provides a slightly expansion for allowing to initially release and reseal the bottle neck.
