Folding box

1. A folding box ( 10 ) having

a polygonal outer contour unit ( 12 ) closed in cross section and having outer wall elements ( 30 . 1 , 30 . 2 , 30 . 3 , 30 . 4 ) connected via outer-contour folding lines ( 32 ),

a lid unit ( 18 ),

a base unit ( 20 ), and

a reclosable removal opening ( 80 ), which comprises

a bottom inner contour unit ( 14 ), regions of which are polygonal in cross section and which has bottom inner wall elements ( 40 . 1 , 40 . 2 , 40 . 3 ) connected via bottom inner-contour folding lines ( 42 . 1 , 42 . 2 ) and which is present in a folded state in the interior of the outer contour unit ( 12 ) and is connected to the outer contour unit ( 12 ) via a connecting folding line ( 28 ),

a polygonal top inner contour unit ( 16 ) which is closed in cross section, has the removal opening ( 80 ) and has top inner wall elements ( 50 . 1 , 50 . 2 , 50 . 3 , 50 . 4 ) connected via top inner-contour folding lines ( 52 . 1 , 52 . 2 , 52 . 3 ) and which is present in a folded state in the interior of the outer contour unit ( 12 ),

at least one connecting folding tab ( 60 ) which connects the bottom inner contour unit ( 14 ) and the top inner contour unit ( 16 ) to one another and can be folded into the interior of the folding box ( 10 ),

the folding or stretching of the connecting folding tab ( 60 ) permitting a relative displacement of the top inner contour unit ( 16 ) relative to the outer contour unit ( 12 ), the removal opening ( 80 ) being closed by the outer contour unit ( 12 ) when the top inner contour unit ( 16 ) is pushed into the outer contour unit ( 12 ), the removal opening ( 80 ) being opened in the pulled-out state of the top inner contour unit ( 16 ), and the outer contour unit ( 12 ) forming a displacement guide for the top inner contour unit ( 16 ).

2. The folding box as claimed in claim 1 , wherein the sum of the lengths (L 2 +L 3 ) of the top and bottom inner contour units ( 14 , 16 ) essentially corresponds to the length (L 1 ) of the outer contour unit ( 12 ).

3. The folding box as claimed in claim 1 or 2 , wherein the outer contour unit ( 12 ) has at least one marginal recess ( 82 ) open at the top, so that a region of at least one top inner wall element ( 50 . 1 ) is accessible.

4. The folding box as claimed in claim 3 , wherein there are two marginal recesses ( 82 ) on opposite outer wall elements ( 30 . 1 , 30 . 3 ).

5. The folding box as claimed in claim 1 or 2 , wherein an outer-contour adhesive tab ( 24 ) is attached to the outer contour unit ( 12 ) via an adhesive-tab folding line ( 26 ) and is designed as a full-surface wall element.

6. The folding box as claimed in claim 1 or 2 , wherein the connecting folding tab ( 60 ) is attached to the bottom inner contour unit ( 14 ) via a first connecting folding line ( 62 ) and to the top inner contour unit ( 16 ) via a second connecting folding line ( 64 ), the connecting folding lines ( 62 , 64 ) being arranged perpendicularly to the inner folding lines ( 42 , 52 ).

7. The folding box as claimed in claim 1 or 2 , wherein the connecting folding tab ( 60 ) has a centrally arranged inner folding line ( 66 ) which is arranged parallel to the connecting folding lines ( 62 , 64 ).

8. The folding box as claimed in claim 1 or 2 , wherein, lid folding tabs ( 68 . 1 , . . . ) forming the lid unit ( 18 ) are integrally formed on the top inner contour unit ( 16 ) via lid folding lines ( 69 ).

9. The folding box as claimed in claim 1 or 2 , wherein base folding tabs ( 70 . 1 , . . . ) forming the base unit ( 20 ) are integrally formed on the bottom inner contour unit ( 14 ) via base folding lines ( 71 ).

10. The folding box as claimed in claim 1 or 2 , wherein

the outer contour unit ( 12 ) has a quadrilateral cross section having four outer wall elements ( 30 . 1 , . . . ),

the bottom inner contour unit ( 14 ) has a U-shaped cross section having three bottom inner wall elements ( 40 . 1 , . . . ), and

the top inner contour unit ( 16 ) has a quadrilateral cross section having four top inner wall elements ( 50 . 1 , . . . ), the dimensions of the inner contour units ( 14 , 16 ) being slightly smaller than the dimensions of the outer contour unit ( 12 ).

11. The folding box as claimed in claim 1 or 2 , wherein the width (BV) of the connecting folding tab ( 60 ) corresponds to the width (B 11 ) of the top and bottom inner wall elements ( 40 . 1 , 50 . 1 ), respectively.

12. The folding box as claimed in claim 10 , characterized in that there are two connecting folding tabs ( 60 ), which are arranged at a distance apart by the dimension of the width (B 22 ) of an inner wall element ( 50 . 2 ) lying in between.

13. The folding box as claimed in claim 1 or 2 , wherein the lid unit ( 18 ) is designed as an adhesively bonded lid unit.

14. The folding box as claimed in claim 1 or 2 , wherein the folding box is formed from a one-piece carton blank.

15. The folding box as claimed in claim 11 , characterized in that there are two connecting folding tabs ( 60 ), which are arranged at a distance apart by the dimension of the width (B 22 ) of an inner wall element ( 50 . 2 ) lying in between.
