an inner wrap ( 4 ) which encloses a group of tobacco articles, and is housed on the inside of the container ( 2 ); and
a collar ( 13 ), which embraces the inner wrap ( 4 ), is internally glued to the container ( 2 ), and protrudes from the open upper end of the container ( 2 ) and has: a collar front wall ( 14 ), two collar lateral walls ( 15 ) and a collar upper wall ( 16 ) which is perpendicular to the collar front wall ( 14 ); and
wherein the collar ( 13 ) has a pull-out opening ( 18 ) for the tobacco articles which involves a portion of the collar front wall ( 14 ) and a portion of the collar upper wall ( 16 ); and
wherein the collar upper wall ( 16 ) comprises a fixed frame which is “U”-shaped and surrounds an upper part of the pull-out opening ( 18 ) on three different sides.

2. The pack ( 1 ) for tobacco articles according to claim 1 wherein the collar ( 13 ) comprises a collar rear wall ( 17 ) which is perpendicular to the collar upper wall ( 16 ), is parallel and opposite to the collar front wall ( 14 ), and overlaps the container rear wall ( 11 ).

3. The pack ( 1 ) for tobacco articles according to claim 2 , wherein the collar rear wall ( 17 ) laterally has a pair of connecting flaps ( 39 ), which are arranged at opposite sides of the collar rear wall ( 17 ), are folded by 90° relative to the collar rear wall ( 17 ), and are glued to the corresponding collar lateral walls ( 15 ).

4. The pack ( 1 ) for tobacco articles according to claim 1 , wherein the pull-out opening ( 18 ) for the collar ( 13 ) is defined by a through-incision which is made through the collar ( 13 ) and delimits internally a mobile portion ( 19 ) of the collar ( 13 ) that at least initially closes the pull-out opening ( 18 ).

5. The pack ( 1 ) for tobacco articles according to claim 4 , wherein:
the through-incision defining the pull-out opening ( 18 ) has a “U” open shape; and
the mobile portion ( 19 ) of the collar ( 13 ) always remains connected to the remaining part of the collar ( 13 ) and is connected to the remaining part of the collar ( 13 ) along a hinge line ( 20 ).

6. The pack ( 1 ) for tobacco articles according to claim 5 , wherein the mobile portion ( 19 ) of the collar ( 13 ) is glued to the inner face of the lid front wall ( 10 ) to obtain the opening and the closing of the mobile portion ( 19 ) by exploiting the movement of the lid ( 3 ).

7. The pack ( 1 ) for tobacco articles according to claim 6 , wherein a lower element ( 20 ) of the mobile portion ( 19 ) is glued to the inner face of the lid front wall ( 10 ), said lower element ( 20 ) being initially arranged at the collar front wall ( 14 ) and being separated from the remaining part of the mobile portion ( 19 ) by a first pre-weakened folding line ( 22 ).

8. The pack ( 1 ) for tobacco articles according to claim 6 , wherein the mobile portion ( 19 ) is provided with a second pre-weakened folding line ( 23 ) which is initially arranged astride between the collar front wall ( 14 ) and the collar upper wall ( 16 ), and with a third pre-weakened folding line ( 23 ) which is initially arranged at the collar upper wall ( 16 ).

9. The pack ( 1 ) for tobacco articles according to claim 6 , wherein the mobile portion ( 19 ) of the collar ( 13 ) is provided with a second pre-weakened folding line ( 23 ) which is initially arranged astride between the collar front wall ( 14 ) and the collar upper wall ( 16 ), and with two third pre-weakened folding lines ( 23 ) which are arranged between the first pre-weakened folding line ( 22 ) and the second pre-weakened folding line ( 23 ).

10. The pack ( 1 ) for tobacco articles according to claim 7 , wherein an outer surface ( 40 ) of the lower element ( 21 ) of the mobile portion ( 19 ) of the collar ( 13 ) is glued to the inner face of the lid front wall ( 10 ) so that when the lid ( 3 ) is arranged in a closed position the mobile portion ( 19 ) has a flat configuration at a corresponding lower element ( 21 ).

11. The pack ( 1 ) for tobacco articles according to claim 7 , wherein an inner surface ( 41 ) of the lower element ( 21 ) of the mobile portion ( 19 ) is glued to the inner face of the lid front wall ( 10 ) so that when the lid ( 3 ) is arranged in a closed position the mobile portion ( 19 ) of the collar ( 13 ) has a “U”-shaped configuration at a lower element ( 21 ).

12. The pack ( 1 ) for tobacco articles according to claim 4 , wherein:
the through-incision defining the pull-out opening ( 18 ) has a closed shape; and
the mobile portion ( 19 ) of the collar ( 13 ) is removable from the collar ( 13 ), thus leaving the pull-out opening ( 18 ) always open, the first time the pack ( 1 ) is opened or during the manufacturing of the pack ( 1 ) for tobacco articles.

13. The pack ( 1 ) for tobacco articles according to claim 12 , wherein the mobile portion ( 19 ) is glued to an underlying removable tear-off upper portion of the inner wrap ( 4 ).

15. The pack ( 1 ) for tobacco articles according to claim 1 , wherein the collar upper wall ( 16 ) comprises a pair of connecting flaps ( 38 ), each of which is hinged to the collar upper wall ( 16 ), is folded by 90° relative to the collar upper wall ( 16 ), and is glued to a corresponding collar lateral wall ( 15 ).

16. The pack ( 1 ) for tobacco articles according to claim 1 , wherein each collar lateral wall ( 15 ) comprises a connecting flap ( 38 ), which is hinged to the collar lateral wall ( 15 ), is folded by 90° relative to the collar lateral wall ( 15 ), and is glued to the collar upper wall ( 16 ).

17. The pack ( 1 ) for tobacco articles according to claim 1 , wherein:
the inner wrap ( 4 ) has a narrower cross section compared to the cross section of the container ( 2 ); and
the collar ( 13 ) comprises at least one support element ( 25 ), which projects from a corresponding collar lateral wall ( 15 ) and rests against the inner wrap ( 4 ) to help keep the inner wrap ( 4 ) in the correct position.

18. The pack ( 1 ) for tobacco articles according to claim 17 , wherein the support element ( 25 ) is, in its cross sectional view, “L”-shaped and comprises a first panel ( 26 ) which originates from a corresponding collar lateral wall ( 15 ) and is perpendicular to the collar lateral wall ( 15 ), and a second panel ( 27 ), which is joined to the first panel ( 26 ), originates from the collar front wall ( 14 ), is perpendicular to the front wall ( 14 ) and rests against a corresponding inner wrap lateral wall of the inner wrap ( 4 ).
