OG exemplary drawing
 
1. A spout for a container, in particular a sealed package, filled with a pourable product;
the spout comprises at least:
a collar having a pouring outlet configured to allow an out-pouring of the pourable product; and
a lid assembly having a coupling ring rotatably arranged around the collar and a lid hinged to the coupling ring and angularly movable around a respective hinge axis;
wherein the lid is controllable between at least:
a closing configuration in which the lid is in a closing angular position with respect to the hinge axis and in which the lid is configured to cover and/or covers the pouring outlet;
an open configuration in which the lid is in an open angular position with respect to the hinge axis and in which the lid is configured to be detached and/or is detached from the pouring outlet; and
an intermediate configuration in which the lid is in an intermediate angular position with respect to the hinge axis interposed between the closing angular position and the open angular position;
wherein the spout comprises an interaction device partially associated to the collar and partially associated to the lid;
wherein the interaction device is configured such that control of the lid from the closing configuration to the intermediate configuration is possible only by rotation of the lid and the coupling ring around a rotation axis and such that control of the lid from the intermediate configuration to the closing configuration is possible by a sole angular movement of the lid around the hinge axis from the intermediate angular position to the closing angular position.
