Abstract

An expansible bottle stopper includes a body, a resilient member, and a movable member that is longitudinally movable relative to the body. The resilient member is caused to expand radially by a first-stage longitudinal displacement of the movable member relative to the body or to shrink radially by a second-stage longitudinal displacement of the movable member relative to the body.
