A combined bottle opener and stopper comprises a metal plate with side edges bent downward and inwardly. Opening is performed with the use of a conventional pry off method. Opened bottles are closed with a rubber pad attached to the bottom of a recess on the inner face of the plate. The opener-stopper has three bent edges which have different heights with the difference corresponding to the pitch of the thread on a threaded bottle neck. For temporary closing the bottle, i.e., with beer or carbonated water, the device is screwed onto the threaded bottle neck as a nut until the rubber pad is tightly pressed to the upper face of the bottle to hermetically close the latter. For closing bottles with nonthreaded bottle necks, the device is moved onto the bottle neck by guiding the convergent bent edges over the neck in a direction transverse to the bottle's axis until the device is fixed tightly on the bottle due to convergence of the bent edges with the rubber pad, thereby to seal the bottle's opening. The device is also provided with sharp edges for cutting plastic wrappings around the bottle neck and with an opener for metal cans openable by pulling up a tongue connected to a scored can cover.
