A stopping device intended particularly for fitting a bottle having a body without symmetry of revolution with a stopping element also without symmetry of revolution, in such a way that the latter, in the stopping up position, has a predetermined orientation relative to the bottle. It comprises stopping means providing omnidirectional obturation in form of an elastic cylindrical skirt insertable frictionally into the throat of the bottle, means for axial and angular positioning of the stopping element, in form of projections or lugs on the stopping element, insertable through elastic deformation into lodgings formed on the bottle in a predetermined angular position, the configurational cooperation of the projections and lodgings ensuring univocal angular orientation of the stopping element and its holding in the axial position on the bottle. |
