Abstract

A pack for smoking articles comprising: a group of smoking articles wrapped by an inner wrap and housed in a rigid outer container provided with a lid hinged to the outer container; a collar partially projecting from an open upper end; and a locking system comprising: a support element arranged in the outer container in contact with the collar and provided with two coupling wings, which project movably outwards to move closer or away from each other; and two first through openings, each obtained through a wall of the lid, houses at least a portion of a corresponding coupling wing, to activate the locking system, preventing the lid from rotating from the closed to the open position. An external action of the user releases the coupling wing to deactivate the locking system. The locking system can be reactivated by rotating the lid from the open position to the closed position.

First claim

The invention claimed is:

1. A pack ( 1 ) for smoking articles comprising:
a group ( 19 ) of smoking articles;
an inner wrap ( 18 ), which wraps the group ( 19 ) of smoking articles;
a rigid outer container ( 2 ), which is cup-shaped, houses the inner wrap ( 18 ) and has an open upper end ( 3 );
a lid ( 4 ), which is cup-shaped, is hinged to the outer container along a hinge ( 5 ) so as to rotate, relative to the outer container ( 2 ), between an open position and a closed position, and has: an open lower end, an upper wall ( 10 ), a front wall ( 11 ) and a rear wall ( 12 ) opposite one another, and two side walls ( 13 ) opposite one another;
a collar ( 14 ), which is folded in a “U” shape, is inserted into the outer container ( 2 ) so as to partially project out of the open upper end ( 3 ), and has: a front wall ( 15 ) and two side walls ( 16 ) opposite one another; and
a locking system ( 21 ), which prevents the lid ( 4 ) from rotating from the closed position to the open position, can be deactivated through an external action of the user, to allow the lid ( 4 ) to rotate from the closed position to the open position, and can be reactivated by rotating the lid ( 4 ) from the open position to the closed position;
wherein:
the locking system ( 21 ) comprises:
a support element ( 22 ), which is arranged in the outer container ( 2 ) in contact with the collar ( 14 ) between the inner wrap ( 18 ) and the collar ( 14 ); wherein the collar ( 14 ) has two seats ( 25 ), in the form of two second through openings or two notches, into which coupling wings ( 23 ) are inserted;
the two coupling wings ( 23 ), which project outwards and are carried by the support element ( 22 ) in a movable manner, so that they can move closer to, or away from one another; and
two first through openings ( 24 ), each of which is obtained through a wall ( 11 , 13 ) of the lid ( 4 ), houses at least a portion of a corresponding coupling wing ( 23 ) in order to activate the locking system ( 21 ), and releases the corresponding coupling wing ( 23 ) arranged inside it when the user acts upon the coupling wing ( 23 ) from the outside in order to deactivate the locking system ( 21 ).

2. A pack ( 1 ) according to claim 1 , wherein the support element ( 22 ) has a main wall ( 26 ) and a pair of appendages ( 27 ), which are coplanar to the main wall ( 26 ), originate from opposite ends of the main wall ( 26 ), are spaced apart and separate from one another and each support a respective coupling wing ( 23 ).

3. A pack ( 1 ) according to claim 2 , wherein the main wall ( 26 ) of the support element ( 22 ) is parallel to a front wall ( 7 ) of the outer container ( 2 ) and to the front wall ( 15 ) of the collar ( 14 ).

4. A pack ( 1 ) according to claim 3 , wherein the front wall of the collar ( 14 ) has an extraction opening ( 20 ) having a transverse extension, which is smaller than a distance between the two appendages ( 27 ) of the support element ( 22 ) so that the front wall of the collar ( 14 ) completely covers the two appendages ( 27 ) of the support element ( 22 ).

5. A pack ( 1 ) according to claim 2 , wherein at least a portion ( 31 ) of the main wall ( 26 ) of the support element ( 22 ) is folded by 180° along a first transverse folding line ( 32 ) against the appendages ( 27 ) and is glued to the appendages ( 27 ).

6. A pack ( 1 ) according to claim 2 , wherein:
the support element ( 22 ) and the collar ( 14 ) are obtained from one single flat element ( 34 ),
the main wall ( 26 ) of the support element ( 22 ) is connected to the front wall ( 15 ) of the collar ( 14 ); and
the appendages ( 27 ) are folded by 180° against the front wall ( 15 ) of the collar ( 14 ).

7. A pack ( 1 ) according to claim 6 , wherein the main wall ( 26 ) of the support element ( 22 ) is connected without gaps to the front wall ( 15 ) of the collar ( 14 ) and the appendages ( 27 ) are folded by 180° along a second transverse folding line ( 33 ) against the main wall ( 26 ) of the support element ( 22 ) and against the front wall ( 15 ) of the collar ( 14 ).

8. A pack ( 1 ) according to claim 6 , wherein the main wall ( 26 ) of the support element ( 22 ) and the front wall ( 15 ) of the collar ( 14 ) are connected to one another by a third transverse folding line ( 33 ), around which they are folded by 180° so as to place the main wall ( 26 ) of the support element ( 22 ) and the appendages ( 27 ) against the front wall ( 15 ) of the collar.

9. A pack ( 1 ) according to claim 1 , wherein the two coupling wings ( 23 ) are aligned with one another transversely and, similarly, the two first through openings ( 24 ) are aligned with one another transversely.

10. A pack ( 1 ) according to claim 1 , wherein the two coupling wings ( 23 ) are not aligned with one another transversely and similarly, the two first through openings ( 24 ) are not aligned with one another transversely.

11. A pack ( 1 ) according to claim 1 , wherein:
the outer container ( 2 ), the lid ( 4 ) and the collar ( 14 ) are made of a paper material; and
the support element ( 22 ) is made of a plastic material.
