This invention relates to closures for glass bottles, in particular, versatile closures for bottling and storing of alcoholic beverages in such bottles. A technical result of the invention is increased bottle sealing reliability. The technical result is on account of design of the closure, which has a body with teeth on its internal surface, a pouring sleeve with a skirt and a liquid stream splitter with longitudinal ribs on its internal side surface, a male thread and fixing teeth that interact with the teeth of the body, windows in the walls of the skirt with transverse protrusions directed inside the pouring sleeve, a lock in the form of hollow cylinder with annular sealing lips on its external surface, said cylinder connected to a larger diameter hollow cylinder by means of a bridge having an external annular flange for fixing in the pouring sleeve, a valve and a cap installed on the pouring sleeve by means of a thread joint. The cap consists of an internal hood with female thread, a locking ring and an external hood with interlocks in the form of longitudinal splines. The body and the skirt of the pouring sleeve have retaining annular protrusions located on the internal surface of the body and the external surface of the skirt above the windows; the inner hood has a recess on its end face and the external hood has a multifaceted hollow protrusion on the internal surface of its top face matching the said recess; the external hood has a barrel-shaped extra hood; there is a multifaceted protrusion on its external bottom surface, which is congruent with the multifaceted protrusion on the external hood and interacts with it. The liquid stream splitter is a disc with a central hole and circumferential ports that are formed by bridges connecting the disc and the pouring sleeve. The valve is a disc with a rod located in its center coaxially and able to close the central hole of the stream splitter. There is a recess on the external surface of the barrel bottom; said recess mates the protrusion on the top face of the external hood. The larger diameter hollow cylinder of the lock has annular sealing lips on its external surface and longitudinal stiffening ribs spaced equally on its internal surface. The valve rod has a through hole. The barrel is shaped as a cylinder or a truncated cone, or a truncated multifaceted pyramid and its top is covered with a protective cap, which has a protrusion interacting with the internal surface of the barrel. The body has a decorative shell made of metal foil and shaped as an annular ribbon.
