Abstract

L'invention présente une fermeture à ouverture automatique en matière plastique. Cette fermeture comprend une partie de base (1) avec un bec verseur (13), dans lequel une douille d'ouverture automatique (3) est disposée d'une manière mobile. Cette douille agit en liaison avec un capuchon tournant, de telle sorte que, lors du premier enlèvement du capuchon tournant, elle soit entraînée par ce dernier et traverse de ce fait la paroi du récipient. Pour obtenir un écoulement de liquide aussi uniforme que possible lors du versement subséquent de liquide hors du récipient et pour éviter un glougloutement, on a disposé, dans la douille d'ouverture automatique, une structure de séparation (5) qui subdivise l'ouverture de passage délimitée par la douille d'ouverture automatique en une ouverture de versement (51) et une ouverture d'entrée d'air (52), plus petite et séparée de la première.
