An automatically opening pour spout fitment (10) to be applied to a container over location where the container wall has a weakened area. The automatically opening fitment (10) is comprised of a cap (20) which is threadably attached to the fitment (40) and which has a depending cam (24) extending downward from the top wall. The fitment (40) is comprised of a annular sidewall (46) which defines a pouring zone and which provides a boundary for a hinged flap (42). The flap (42) has an upwardly extending cam follower (44) which is engaged by the cam (24) of the cap (20) such that when the cap (20) is removed from the fitment (40), the cam (24) initially applies a horizontal force on the cam follower (44) to open the package to which the fitment is attached to.

L'invention concerne un ensemble bec verseur à ouverture automatique qui est destiné à être appliqué sur un contenant au-dessus d'un endroit où la paroi du contenant comporte une zone plus fragile. L'ensemble à ouverture automatique est constitué d'un bouchon qui est attaché par un filetage à l'ensemble et comporte une came qui s'étend vers le bas depuis la paroi supérieure. L'ensemble est formé d'une paroi latérale annulaire qui définit une zone de versement et qui constitue une limite pour un rabat relié par charnière. Le rabat comporte un suiveur de came qui s'étend vers le haut lequel est bloqué par la came du bouchon de sorte que lorsque le bouchon est ôté de l'ensemble, la came applique au départ une force horizontale sur le suiveur de came pour ouvrir le contenant sur lequel est fixé l'ensemble.
