Abstract (en)
The stopper is of the type comprising an upper portion forming the stopper body (1) as such, configured by a hollow cylinder of revolution open at the lower end and provided on the inner sidewall thereof with an outwardly extending thread. A circular skirt (2) is attached to the stopper body by way of points or threads (3) which may break on unscrewing. The invention relates to the means that said skirt includes for retention below the arcuate ridge with which bottlenecks are provided. These means are formed by protuberances (5) hollowed out in the outside/inside direction. The projection towards the inner side of said protuberances of semispherical or similar shape, can yield when screwing on the stopper, passing over the thread area and the neck ridge, providing on the other hand sufficient strength on unscrewing the stopper to cause the points or threads to break.
