Package with curved edges
Provided is a package made of a composite material is represented and described, including a package base with two front base corners and with two rear base corners, a package gable with two front gable corners and with two rear gable corners, and a package base body with a front panel, a first side panel, a second side panel and a rear panel. The package base and the package gable are arranged on opposite sides of the package base body. The composite material has a polymer inner layer, a polymer outer layer and a fibrous support layer, which is arranged between the polymer outer layer and the polymer inner layer. In order to enable the manufacture of packages with even more complex geometries without impairing the rigidity of the package, it is proposed to provide a third sleeve fold line, which has a plurality of sections, which each adjoin a side panel and the rear panel, and of which at least one section is curved.
1. A package made of composite material, comprising:
a package base with two front base corners and with two rear base corners,
a package gable with two front gable corners and with two rear gable corners, and
a package base body with a front panel, a first side panel, a second side panel and a rear panel,
wherein the package base and the package gable are arranged on opposite sides of the package base body,
wherein the composite material has a polymer outer layer, a polymer inner layer and a fibrous support layer, which is arranged between the polymer outer layer and the polymer inner layer, and
a third sleeve fold line, which has a plurality of sections, which each adjoin a side panel and the rear panel, and of which at least one section is curved,
wherein at least one section of the third sleeve fold line is straight and/or at least two sections of the third sleeve fold line have opposite curvature directions.
2. The package according to claim 1 , wherein the third sleeve fold line ends with one of its two ends at one of the two rear gable corners and ends with its other end at one of the two rear base corners.
3. The package according to claim 2 , wherein the section of the third sleeve fold line adjoining the package base and the section of the third sleeve fold line adjoining the package gable are straight.
4. The package according to claim 1 , wherein the package base body has at least one stress-relief panel which is arranged between the front panel and one of the two side panels.
5. The package according to claim 4 , wherein the stress-relief panel and the front panel adjoin the same edge of the package, in particular an edge of the package base.
6. The package according to claim 4 , wherein the stress-relief panel and one of the two side panels adjoin the same edge of the package, in particular an edge of the package gable.
7. The package according to claim 4 , wherein a first sleeve fold line, which is preferably curved at least in sections, is provided between at least one stress-relief panel and the adjoining front panel.
8. The package according to claim 7 , wherein the first sleeve fold line ends only with one of its two ends at one of the two front gable corners or at one of the two front base corners and does not end with its other end at a gable corner or at a base corner.
9. The package according to claim 1 , wherein a second sleeve fold line, which is preferably curved at least in sections, is provided between at least one stress-relief panel and the adjoining side panel.
10. The package according to claim 9 , wherein the second sleeve fold line ends only with one of its two ends at one of the two front gable corners or at one of the two front base corners and does not end with its other end at a gable corner or at a base corner.
11. The package according to claim 1 , wherein the package has a fin seam in a region of the package gable, which is turned over in the direction of the front panel.
12. The package according to claim 1 , wherein the package gable is approximately trapezoidal.
13. The package according to claim 1 , wherein the package gable is an oblique gable.
14. The package according to claim 1 , wherein the package gable has a front edge, which is curved and which adjoins the front panel.
15. The package according to claim 1 , wherein the front panel is convex and/or the rear panel is at least partially concave.
16. The package according to claim 15 , wherein the front panel has its maximum convex bulge above half the height of the package base body.
17. The package according to claim 1 , wherein the two front gable corners have two large gable corner angles, which are each greater than 90°.
18. The package according to claim 1 , wherein the two rear gable corners have two small gable corner angles, which are each smaller than 90°.
19. The package according to claim 1 , wherein the four gable corner angles have an angle sum, which is greater than 360°.
