Moreover, interaction ridge 29 may have an annular shape.
Preferentially, interaction ridge 29 is axially displaced from the contact portion, in particular such that interaction ridge 29 is interposed between main wall 26 and the contact portion. In other words, the contact portion is axially closer to the second axial end of side wall 27 than interaction ridge 29.
According to some preferred non-limiting embodiments, interaction ridge 29 is arranged such that the contact portion is axially closer to rim 18 than interaction ridge 29, in particular with lid 12 being in the initial position and/or with lid-assembly 3 being in the initial configuration and/or prior to the first-time control of lid 12 in the open position.
In particular, interaction ridge 29 is axially displaced from rim 18 with lid 12 being in the initial position and/or lid-spout assembly 3 being in the initial configuration.
Moreover, interaction ridge 29 may be arranged and designed such that once lid-spout assembly 3 is in the used configuration and lid 12 is controlled in the closed position, interaction ridge 29 is placed within flow channel 17.
Furthermore, side wall 27 may be designed such that a main portion of side wall 27 carrying interaction ridge 29 is arranged outside of flow channel 17 with lid 12 being arranged in the initial position and/or with lid-spout assembly 3 being in the initial configuration.
Moreover, side wall 27 may be designed such that a first portion 31 of side wall 27 is placed within flow channel 17 and a second portion 32 of side wall 27 is arranged outside of flow channel 17 with lid 12 being in the closed position.

The interaction surface 34 may be designed to abut against an abutment surface 35 of collar 15, in particular of rim 18. Preferentially, abutment surface 35 faces inlet opening 16 and/or rim 19.
According to some preferred non-limiting embodiments, tethering element 13 is connected to collar 15. In particular, the connection between tethering element 13 and collar 15 defines hinge axis B.
Moreover, tethering element 13 may be bendable and/or flexible and/or deflectable.
Preferentially, tethering element 13 is configured to modify its shape in dependence on the position of lid 12. Even more preferentially, tethering element 13 is controllable between at least a first configuration with lid 12 being in the closed position and a second configuration (distinct from the first configuration) with lid 12 being in the open configuration.
With particular reference to
In particular, tethering element 13 is designed to be (temporarily) coupled to retaining group 38 for retaining lid 12 in the open position.
Preferentially, lid spout-assembly 3 further comprises a connection base 39 fixed to and protruding, in particular laterally protruding away, from base frame 14 and carrying retaining group 38.
Preferentially, retaining group 38 comprises a hook element 40 configured to interact with tethering element 13 for retaining lid 12 in the open position.
Preferentially, hook element 40 transversally, in particular perpendicularly, extends from connection base 39.
According to some preferred non-limiting embodiments, tethering element 13 comprises a recess 41 configured to engage retaining group 38, in particular hook element 40, so as to (at least) temporarily fix lid 12 in the open position.
In use, the outpouring of the pourable product from package 1 requires to control lid 12 in the open position so as to open pouring outlet 11. In particular, the first-time lid 12 is controlled in the open position, in particular from the initial position, lid-spout assembly 3 is controlled from the initial configuration to the used configuration and afterwards, it is possible to repeatedly control lid 12 between the closed position and the open position.
Each time lid 12 is controlled in the closed position, interaction ridge 29 interacts with collar 15, in particular rim 18, so as to lock lid 12 in the closed position by generating a closing force. This closing force must be overcome in order to move lid 12 again to the open position.
In particular, with lid 12 being in the closed position, interaction surface 34 abuts against abutment surface 35.
The advantages of lid-spout assembly 3 and/or of package 1 according to the present invention will be clear from the foregoing description.
In particular, by providing for interaction ridge 29 it is possible to lock lid 12 in the closed position, thereby reducing or even avoiding any uncontrolled movement of lid 12 from the closed position to the open position.
Another advantage resides in that interaction ridge 29 in collaboration with collar 15, in particular rim 18, defines a seal laterally sealing pouring outlet 11 when lid 12 is arranged in the closed position. Preferentially, this allows to avoid and/or limit any (substantial) lateral leakages.
Clearly, changes may be made to lid-spout assembly 3 and/or package 1 as described herein without, however, departing from the scope of protection as defined in the accompanying claims.
