OG exemplary drawing
 
1. Lid-spout assembly for a package having a designated pour opening and being filled with a pourable product;
the lid-spout assembly comprises at least:
a spout having a collar carrying a pouring outlet;
a coupling ring arranged around a portion of the collar;
a lid configured to selectively close and open the pouring outlet; and
a hinge element hinging the lid to the coupling ring and defining a hinge axis around which the lid is angularly movable;
wherein the lid is controllable between at least:
a closed configuration in which the lid is in a first angular position with respect to the hinge axis and in which the lid is configured to cover and/or covers the pouring outlet; and
an open configuration in which the lid is in a second angular position with respect to the hinge axis and in which the lid is configured to open the pouring outlet;
wherein the lid-spout assembly is designed such that the lid is controllable between the closed configuration and the open configuration by means of an angular movement around the hinge axis;
wherein the lid-spout assembly comprises an interaction assembly partially associated to the collar and partially associated to the lid;
wherein the interaction assembly is designed such to determine a threshold force needed to be exceeded, in use, in order to control the lid from the closed configuration to the open configuration,
wherein the interaction assembly comprises an interaction member associated to the collar and an interaction element associated to the lid,
wherein the interaction member and the interaction element are configured to interact with one another so as to define the threshold force,
wherein the interaction member comprises a first sliding surface and the interaction element comprises a first engagement surface,
wherein the first sliding surface and the first engagement surface are designed such that during the exertion of an opening force for angularly moving the lid from the first angular position to the second angular position the first engagement surface abuts against the first sliding surface impeding the angular movement if the opening force is below or equals the threshold force and slides over the first sliding surface if the opening force exceeds the threshold force.
