Flaschen Verschluss mit gegen Wiederfüllen Garantiering sowie Sicherung

摘要

The device comprises a pourer body (7) which is locked in the orifice (2) of the bottle (3) by means of a tubular seal (8) at the lower end of which is the seat (18) on which the stop means (19) of the valve rests. The pourer is locked elastically and leaktightly against the seal by its cylindrical wall (10) which includes an annular zone or band (14) that is designed to sever if the pourer is tampered with. The seal (8) in turn is locked elastically and leaktightly in the orifice of the bottle by means of a series of elastic circular flanges (17) which both prevent the liquid from escaping and anchor the seal in the mouth of the bottle. The tearing of the preferentially severable band (14) by illicit forcing of the pourer will detach the pourer from the bottle and allow the valve stop means (19) to escape when the liquid is poured out. The presence of the elastic flanges on the seal means that the closure device can be adapted to different bottle mouths.
