The present invention relates to a device (10) including: - a base (11) intended to be assembled onto a container neck and comprising a skirt (16) and a transverse wall (15) having an opening (20); and - a cover (12) coaxially mounted onto and around the base and comprising a transverse wall (50) and a skirt (51) having a window (52). Projections (58) arranged on the cover move in grooves (25) arranged on the base so that the cover is movable between: - a closed position, wherein the transverse surfaces of the base and the cover are adjacent to each other, the opening and the window being closed off; and - an open position, where an intermediate chamber, wherein a pellet contained in the container can enter via the opening of the base then exit via the window of the cover, is created between the base and the cover. |
