The sealing device includes: a specially designed sealing opening for the neck of the container. The sealing opening includes a jet opening and a closed cover consisting of an upper wall and a skirt. The sealing device is specially designed according to the difference between the upper wall and the skirt for installation on the sealing. This is the first time that a retention arrangement has been made for sealing seals, and the second time is basically a continuous retention arrangement.

The present invention relates to a closure assembly comprising a closure spout (1) adapted to be fitted to the neck of a container and a closure cap. The closure spout (1) comprises a dispensing opening. The closure cap comprises an upper wall and a skirt depending therefrom, adapted to be fitted to the closure spout to close the container, especially for use on pressurized containers such as carbonated beverage containers. At least one substantially continuous second retaining arrangement (5) on said closure spout (1) has one ore more elongate second retaining segments (6). The lower second retaining surface (8) has no pitch or at least a relatively lower pitch in a first region (9),a relatively higher pitch in a second region (10) displaced from the first region (9) in an unscrewing direction (30) and has no pitch or at least a relatively lower pitch in a third region (11) displaced from said second region (10) in a unscrewing direction (30).
