Stopper comprises a cylindrical body (1) of cork or moulded plastic with a head (2) in the shape of a collar with a central aperture (6) which receives the upper end of the body. The inner surface of the aperture in the stopper head has a series of radial ribs (4) which are inclined slightly to one side of the radial lines, gripping the upper part of the body. Stopper comprises a cylindrical body (1) of cork or moulded plastic with a head (2) in the shape of a collar with a central aperture (6) which receives the upper end of the body. The upper surface (2A) of the collar can lie flush with the top of the stopper body (5A), and both the collar and top of the body can be used to carry information of a technical, hygiene or commercial nature. The inner surface of the aperture in the stopper head has a series of radial ribs (4) which are inclined slightly to one side of the radial lines, gripping the upper part of the body so it can be rotated to facilitate removal. In addition, the stopper can have a hole through it to receive a straw or pouring spout.
