Spout for a container and package-spout assembly

A spout for a sealed package filled with a pourable product, the spout comprising:

• a collar having a pouring outlet configured to allow an out-pouring of the pourable product;
• 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 hinge axis;
• wherein the lid is movable 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 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 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;
• a main interaction structure on the collar and a main interaction unit on the lid that interact with one another 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;
• the main interaction structure on the collar including an abutment surface on the collar and a guiding surface on the collar, the guiding surface being different from the abutment surface;
• the main interaction unit on the lid including a first engagement surface on the lid that is configured to abut against the abutment surface during rotation of the lid in a rotational direction around the rotation axis between a first angular lid position and a second angular lid position so that as the first engagement surface abuts against the abutment surface during the rotation of the lid between the first and second angular lid positions, angular movement of the lid around the hinge axis from the closing angular position to the intermediate angular position is prevented;
• and
• the main interaction unit also including a second engagement surface on the lid that is configured to slide along the guiding surface during rotation of the lid in the rotational direction around the rotation axis between a third angular lid position and a fourth angular lid position so that as the second engagement surface slides along the guiding surface between the third and fourth angular lid positions the lid angularly moves around the hinge axis from the closing angular position to the intermediate angular position, the third angular lid position and the fourth angular lid position being between the second angular lid position and the first angular lid position in the rotation direction.
