OG exemplary drawing
 
1. A spout for a sealed package filled with a pourable product;
the spout comprises at least:
a base frame configured to be fitted about a designated pour opening surface area of the sealed package;
an opening assembly moveably coupled to the base frame, the opening assembly comprising a movable cutter adapted to at least partially cut and/or rupture and/or open and/or pierce the designated pour opening surface area as the cutter moves from a rest configuration to an operative configuration; and
a control device configured to interact with the cutter and to control movement of the cutter from the rest configuration to the operative configuration in which the cutter with the base frame being, in use, fitted about the designated pour opening surface area is configured to at least partially cut and/or rupture and/or open and/or pierce the designated pour opening surface area;
wherein the control device comprises:
at least one interaction element connected to the cutter so that the cutter and the interaction element move together;
at least one control ring rotatably coupled to the base frame around a respective rotation axis; and
at least one interaction member connected to and/or coupled to the control ring and configured to interact with the interaction element;
wherein the interaction member is coupled and/or connected to the control ring such that a rotation of the control ring induces also a rotation of the interaction member;
wherein the interaction member comprises an axial end portion being arranged within a rotation plane being orthogonal to the rotation axis;
wherein, in use, upon rotation of the control ring around the rotation axis the interaction member interacts with the interaction element to induce a translation of the cutter of the opening assembly from the rest configuration to the operative configuration;
wherein, in use, upon rotation of the control ring the rotation plane is fixed with respect to the base frame.
