5. The method according to claim 1, wherein the at least one profiled structure in the interior comprises at least one thread.

6. The method according to claim 1, wherein the subsequent arrangement comprises: sliding a sleeve comprising the at least one profiled structure onto the neck, and gluing or pressing the sleeve to the neck to maintain a permanent connection between the sleeve and the neck, or sliding a wetted sleeve comprising the at least one profiled structure onto the neck, and drying the sleeve to maintain a permanent connection between the sleeve and the neck.

7. The method according to claim 1, wherein the subsequent arrangement comprises: winding a band-like cutting comprising the at least one profiled structure onto the neck, and gluing or pressing the band-like cutting to the neck to maintain a permanent connection between the band-like cutting and the neck.

8. The method according to claim 1, wherein the subsequent arrangement comprises: spraying the at least one profiled structure onto the neck by means of at least one spray nozzle.

9. The method according to claim 8, further comprising drying the at least one profiled structure.

10. The method according to claim 8, wherein the spraying comprises: rotating the blank about its longitudinal axis and thereby adjusting the height of the blank in order to spray on a thread revolving around the neck, and/or rotating the blank about its longitudinal axis and spraying a support ring on the neck.

11. The method according to claim 8, wherein the spraying comprises: directing the at least one spray nozzle along a spiral path on the neck to spray a thread revolving around the neck.

12. The method according to claim 1, wherein the at least one profiled structure is coated after the subsequent arrangement.

13. A device for carrying out the method according to claim 1, wherein the device comprises: a molding device for producing the blank of the container from the material, wherein the blank comprising the bottom, the sidewall and the neck, an arrangement device for arranging the at least one profiled structure on the neck of the blank.

14. The device according to claim 13, further comprising: a sliding device for sliding the sleeve comprising the at least one profiled structure onto the neck; or a winding device for winding the band-like cutting comprising the at least one profiled structure onto the neck, or a spraying device comprising the at least one spray nozzle for spraying the at least one profiled structure onto the neck.

15. The device according to claim 13, further comprising a coating device for coating the at least one profiled structure.

DETAILED DESCRIPTION

[0042] FIG. 1A shows a blank 1 of the container, wherein the blank comprises a bottom 2, a sidewall 3, a shoulder region 6, a neck 4 and a mouth opening. To produce the container, a profiled structure in the form of a sleeve is also applied to the neck 4 of the blank 1.

[0043] FIG. 1B shows a tube material 7 comprising the at least one profiled structure 8, in this case in the form of a thread 8. The tube material 7 is designed in such a way that individual sleeves can be cut off and/or separated therefrom, which can then be applied to the neck 4 of the blank 1. Cutting off and/or separating the individual sleeves can be done along a separating seam 9.

[0044] FIG. 1C shows a sleeve 10 cut off or separated from the tube material 7.

[0045] FIG. 1D shows a container 11 comprising the blank 1 with the sleeve 10 applied. This container 11 can now be closed by means of a corresponding cover, wherein the closure can be designed to be reclosable.

[0046] FIG. 2A shows a blank 1 of the container. To produce the container, a profiled structure in the form of a band-like cutting is also applied to the neck 4 of the blank 1.

[0047] FIG. 2B shows a roller 12 comprising a band-like arrangement of the at least one profiled structure 13, in this case in the form of a thread. The roller 12 is designed in such a way that individual band-like cuttings can be cut off and/or separated, which can then be applied to the neck 4 of the blank 1. Cutting off and/or separating the individual band-like cuttings can be done along a separating seam 14.

[0048] FIG. 2C shows a band-like cutting 15 cut from the roller 12.

[0049] FIG. 2D shows a container 16 comprising the blank 1 with the band-like cutting 15 applied. This container 16 can now be closed by means of a corresponding cover, wherein the closure can be designed to be reclosable.

[0050] FIG. 3A shows a blank 1 of the container. To produce the container, a profiled structure in the form of a thread and a support ring is sprayed onto the neck 4 of the blank 1.

[0051] FIG. 3B shows a container 22 comprising the blank 1 with a sprayed profiled structure, in this case in the form of a thread 20 and support ring 21. Spraying can be done with a spraying device 18 comprising a spray nozzle 19.
