ABSTRACT:
A stopper for bottles, especially for closing uncorked wine and champagne bottles which comprises an elastic deformable sleeve member to be inserted into the bottle neck to be closed, which sleeve member has a mantle section and a closed bottom section and an open top section through which extends a connecting rod rigidly connected to a cap or hood which in inserted position of the stopper surrounds the upper neck portion of the bottle to be closed. The cap or hood forms a handle which is adapted to force the sleeve member into the bottle neck to be closed by stretching the sleeve member. The outer diameter of the piston is slightly less than the inner diameter of the bottle neck portion to be closed by the stopper, and the wall thickness of the sleeve mantle section in non-deformed condition of the sleeve member is greater than the thickness of the annular gap between the outer periphery of the piston and the bottle neck section of the bottle to be closed by the stopper.
