13. The method according to claim 12, wherein the holding comprises a holding at the mouth area of the container body.

14. The method according to claim 12, wherein the attaching comprises: placing the crown cap over the mouth opening and exerting a force substantially parallel to a longitudinal axis of the container body from outside the container body in the direction toward the mouth opening.

15. The method according to claim 12, wherein the attaching comprises: crimping the crown cap onto the mouth opening by exerting a force substantially radially toward a longitudinal axis of the container body.

16. The method according to claim 12, wherein the attaching further comprises: drying and/or solidifying a material of the crown cap by heating the crown cap during attachment.

17. The crown cap of claim 5, wherein the coating is food-safe and/or biodegradable and/or compostable and/or liquid-resistant.

18. The container body of claim 11, wherein the mouth area comprises a rim.

Description

BRIEF DESCRIPTION OF FIGURES

[0036] The accompanying figures show, by way of example, aspects and/or exemplary embodiments of the disclosure for better understanding and illustration. In the figures:

[0037] FIG. 1 is an oblique view of a crown cap for attachment to a mouth opening of a container body comprising fibers and for closing the mouth opening by means of the crown cap,

[0038] FIG. 2 is a cross-section through the crown cap and a mouth area of the container body comprising fibers, and

[0039] FIG. 3 is a cross-section through the crown cap attached to the mouth opening of the mouth area.

DETAILED DESCRIPTION OF FIGURES

[0040] FIG. 1 shows an oblique view of a crown cap 1 for attachment to a mouth opening of a container body comprising fibers and for closing the mouth opening by means of the crown cap 1. The illustration shows an upper side 3 of the crown cap 1 and a first fold 2. The first fold 2 shows the state when the crown cap has not yet been attached to a mouth opening.

[0041] The crown cap 1 can comprise a metal that is for example soft enough for the crown cap 1 to be attached with such force to the mouth opening of a container body comprising fibers without causing damage, such as deformation, to the mouth opening and/or to a mouth area and/or to the container body.

[0042] The crown cap 1 can also or alternatively comprise a material comprising fibers. A fiber-containing pulp can be used to produce the crown cap 1, wherein 3D printing can be used to form the crown cap 1.

[0043] FIG. 2 shows a cross-section through the crown cap 1 and a mouth area 9 of the container body 6 comprising fibers. The crown cap 1 comprises a coating 4 on an inner surface 5. The coating 4 can consist of a sealing material, wherein the coating 4 can be food-safe and/or biodegradable and/or compostable and/or liquid-resistant. The coating 4 can ensure a seal between at least one surface of the crown cap 1 that would come into contact with a surface of the mouth area 9 of the container body 6. In addition, the coating 4 can protect the crown cap, for example if it contains fibers, from softening due to absorbed product, the product can be protected from a change in taste due to the crown cap, and/or the sealing tightness of the crown cap in the closure position can then be supported and/or ensured.

[0044] The mouth area 9 of the container body 6 comprising fibers surrounds the mouth opening of the container body 6 and has a rim 8 and a reinforcement 11. The mouth area 9 is held by a clamp 10 in order to ensure stabilization when the crown cap 1 is attached to the mouth opening 7 of the container body 6 comprising fibers.

[0045] FIG. 3 shows a cross-section through the crown cap 1 attached to the mouth opening 7 of the mouth area 9 of the container body 6 comprising fibers, and through the mouth area 9. The illustration corresponds to a closure position of the crown cap. By attaching the crown cap 1 to the mouth opening 7, the crown cap 1 now has a second fold 12 that forms a fixed but detachable connection with the mouth area 9, so that the container body 6 is closed. The second fold 12 shows the state when the crown cap 1 has been attached to the mouth opening 7.

[0046] The attaching of the crown cap 1 to the mouth opening 7 can comprise a placing of the crown cap 1 over the mouth opening 7 and exerting a force substantially parallel to a longitudinal axis of the container body 6 from outside the container body 6 in the direction toward the mouth opening 7.

[0047] Or the attaching of the crown cap 1 to the mouth opening 7 can comprise a crimping of the crown cap 1 onto the mouth opening 7 by exerting a force substantially radially toward a longitudinal axis of the container body 7.

[0048] If the crown cap 1 comprises fibers, the attaching can further comprise drying and/or solidifying a material of the crown cap 1 by heating the crown cap 1 during attachment.

[0049] From the closure position, the crown cap 1 can be brought into an open position away from the container body 6. In general, the crown cap is not a repeatedly used closure. It can usually be placed on the mouth opening 7 again, but it then no longer has a sealing function.
