The invention concerns a device comprising a pourer (3) designed to be permanently fixed on the neck (2) of a container, and an assembly (4) forming a cover adapted to be mounted on the neck and/or the pourer and comprising a cap (45) mobile between a first position wherein it isolates the neck (2) and the pourer (3) from outside and a second position where it allows access to the neck (2) and to the pourer (3), the pourer (3) being arranged at least partly inside the neck (2). The cap (45) is provided with a skirt (452) extending, in the first position and from an inner surface (453) of the cap, up to inside the neck (2). Said skirt (452) bears at least a flange (456) capable, when the pourer (3) is in the first position and against an inner radial surface (31a) thereof, of exerting a force (F3) urging the pourer (3) against an inside edge (22) of the neck (2). The invention is useful for closing plastic containers.
