A rigid pack for smoking articles with a hinged or sliding lid

A pack (1) for smoking articles comprising:

• a container (2), which is cup-shaped and has:
• an open top end (3), a bottom wall (5) opposite the open top end (3), a front wall (6) and a rear wall (7), which are parallel to and opposite one another, and two side walls (8), which are parallel to and opposite one another;
• an inner wrap (13), which encloses a group of smoking articles and is housed in the container (2);
• a hinged lid (4), which is cup-shaped, is movable between a closed position and an open position, and has:
• an open bottom end, a top wall (9), a front wall (10) and a rear wall (11), which are parallel to and opposite one another, and two side walls (12), which are parallel to and opposite one another;
• a collar (14), which embraces the inner wrap (13) and is glued on the inside of the container (2) so as to partially project out of the open top end (3) and engage a corresponding inner surface of the lid (4), when the lid (4) is arranged in a closed position;
• and
• a slider (19), which is firmly connected to the lid (4) and is coupled to the container (2) in a sliding manner so as to slide relative to the container (2) along a sliding direction (D1);
• wherein there is a locking system (24), which is interposed between the container (2) and the slider (19) and, in the closed position of the lid (4), prevents the slider (19) from sliding relative to the container (2);
• and
• wherein the hindering of the sliding of the slider (19) relative to the container (2), which is determined by the locking system (24), can be deactivated by means of an elastic deformation of at least one of said walls (7, 8) of the container (2) by deforming at least one of said walls (7) of the container (2) inwards or outwards.
