Abstract: Cette invention concerne un distributeur goutte à goutte (1)qui possède un manchon (2) portant une fermeture (9) et un élément souple récepteur (11) de doses. Ce manchon est vissé sur un récipient pourvu d'une tétine (10). La fermeture sur le manchon possède une configuration correspondant à celle de la tétine afin de la rendre étanche lorsqu'elle est en position fermée. On remplit l'élément récepteur avec le liquide provenant du récipient en tournant le manchon dans une direction opposée à la position fermée sur la tétine, c'est à dire dans une position ouverte, établissant ainsi une communication fluidique entre le récipient et l'élément récepteur. On distribue le liquide à partir de l'élément récepteur en pressant cet élément après que la fermeture a retrouvé sa position fermée sur la tétine, empêchant ainsi le liquide de refluer de l'élément récepteur souple vers le récipient. Des éléments de butée coopèrent (12a, 12b) entre le manchon et le goulot (4) de façon à limiter le mouvement du manchon par rapport au goulot.
