Abstract (en)
[origin: WO2012136746A1] A stoppering device to be secured to a container neck comprises a tubular spout (18) defining a passage opening (24), and a plug. The plug (12) has an outer tubular shell (42) sliding on the tubular spout (18), and a bottom (44) provided with a sealing skirt (52) and multiple distribution holes (54). The bottom (44) of the plug engages with the connecting wall of the tubular spout (18) in the plugging position, while preserving an annular retention space (60) between the bottom (44) of the plug and the tubular spout (18). The bottom (44) comprises radial ribs (56) which are in an alternating arrangement between the distribution holes (54), and constitute retention facets retaining the liquid held in the retention space by adhesion. The small volume of liquid which, during the plugging phase, would be prevented from flowing back into the container closed by the stoppering device, can remain in the annular retention space without any particular risk of abrupt ejection, said retention being promoted by the presence of multiple walls in the chamber, in particular the retention facets.
