Abstract

The invention relates to a closed container, delimiting an interior from an exterior, wherein the closed container comprises a sheetlike composite; wherein the sheetlike composite comprises a layer sequence, comprising as mutually superposed layers in a direction from an. inner face of the sheetlike composite to an outer face of the sheetlike composite a) an inner polymer layer, b) a barrier layer, and c) a carrier layer; wherein the closed container is characterised by a shaping coefficient, determined according to the method described herein, in the range from 1.0 to 10.0 m 2 /kg. Further, the invention relates to a method by which a closed container with a shaping coefficient is obtainable; to the closed container obtainable by this method; to an apparatus, designed for producing one of the afore¬ mentioned closed containers; to a use of a sheetlike composite for producing one of the afore¬ mentioned closed containers; and to a use of one of the aforementioned closed containers for storing a foodstuff.

First claim

The invention claimed is:

1. A closed container, delimiting an interior from an exterior, wherein the closed container comprises a sheetlike composite;
wherein the sheetlike composite comprises a layer sequence, comprising as mutually superposed layers in a direction from an inner face of the sheetlike composite to an outer face of the sheetlike composite
a) an inner polymer layer,
b) a barrier layer, and
c) a carrier layer;
wherein the closed container is characterised by a shaping coefficient, determined according to the method described herein, in the range from 1.0 to 10.0 m 2 /kg.

2. The closed container according to claim 1 , wherein the closed container further comprises
a. a base region;
b. a top region; and
c. at least four longitudinal folds, each extending from the base region to the top region.

3. The closed container according to claim 2 , wherein the carrier layer of the sheetlike composite comprises an oriented material,
wherein the oriented material is characterized by a direction of orientation,
wherein the direction of orientation forms an angle of orientation at least with a section of at least one of the at least four longitudinal folds,
wherein the angle of orientation is in a range from 60 to 120°.

4. The closed container according to claim 1 , wherein on a side facing away from the barrier layer the carrier layer is superimposed by a colour application.

5. The closed container according to claim 4 , wherein the colour application adjoins the carrier layer.

6. The closed container according to claim 4 , wherein the colour application comprises a 2D-code.

7. A method, comprising as method steps
a) providing a container precursor, comprising a sheetlike composite, comprising a layer sequence, comprising as mutually superposed layers in a direction from an inner face of the sheetlike composite to an outer face of the sheetlike composite
i) an inner polymer layer,
ii) a barrier layer, and
iii) a carrier layer;

b) filling the container precursor with a foodstuff; and
c) closing the container precursor, thereby obtaining a closed container;
wherein the closed container is characterised by a shaping coefficient, determined according to the method described herein, in the range from 1.0 to 10.0 m 2 /kg.

8. A closed container, obtainable by the method according to claim 7 .

9. The method according to claim 7 , wherein in the method step a) the container precursor comprises at least two longitudinal folds.

10. The method according to claim 9 , wherein the carrier layer of the sheetlike composite comprises an oriented material,
wherein the oriented material is characterized by a direction of orientation,
wherein the direction of orientation forms an angle of orientation at least with a section of at least one of the at least two longitudinal folds,
wherein the angle of orientation is in a range from 60 to 120°.

11. The method according to claim 7 , wherein on a side facing away from the barrier layer the carrier layer is superimposed by a colour application.

12. The method according to claim 11 , wherein the colour application adjoins the carrier layer.

13. The method according to claim 11 , wherein the colour application comprises a 2D-code.

14. An apparatus, designed for producing the closed container according to claim 1 from a container precursor.

15. A use of a sheetlike composite for producing the closed container according to claim 1 .

16. A use of the closed container according to claim 1 for storing a foodstuff.
