The obturating device for tubes, flasks and the like containers of fluids, comprises a valve-cap with a plate, said plate having an upper part with a secondary component protruding at said upper part, blades protruding in middle of an outlet passage for the fluid in order to maintain the secondary component, said plate downwardly extending into a fitting skirt for a neck of the container. The fitting skirt comprises an outer periphery with two diametrically opposed notches with said valve-cap being associated with a casing which comprises a plate having a central hole and an outer fitting skirt with two symmetrically opposed orientating inner ramps. The ramps are used as a bearing member for the notches of the valve-cap. |
