Abstract: A removable stopper for a screw-neck bottle. The bottle has a radial projection arranged transverse to the thread forming a stop at the lower end of the thread. The stopper has a mating internal thread also having a terminal transverse radial projection at the lower end thereof. A second transverse radial projection spaced from and parallel to the terminating projection is formed on the stopper inner wall. The second projection resides on a weakened portion of the stopper wall to permit it to flex radially and pass over the transverse projection on the bottle neck when either applied to or removed from the bottle. The bottle neck projection is closely confined between the two projections on the stopper when in engaged position.
