The device comprises a closure plug (S) for the drink bottle (F). Said plug is provided with an in- let (33, 42) and an inlet valve (34, 43) which is arranged therein and is embodied as a reflux valve that is closed in a rest position. The inventive device also comprises a fill- ing device (E) which is provided with or can be connected to a filling head (H). The closure plug (S) can be coupled to the filling head (H) in a communicating manner. Gas can be inserted into the drink bottle (F) by means of the filling device (E) via the filling head (H) and through the inlet valve (34,43) of the closure plug (S). The filling head (H) opens the inlet valve (34, 43) when the closure plug (S) is coupled. The closure plug (S) is provided with an outlet (45, 38, 37, 36, 39, 41) and an outlet valve (40) that is arranged therein and is embodied as a reflux valve in the rest position.
