Abstract

A package is provided, comprising a packaging material having a bulk layer and being formed into a three-dimensional container by folding the packaging material along predefined crease lines thus forming a fracture along the crease lines. At least one of the crease lines forms a hinge mechanism having a single axis of rotation.

First claim

1 . A package comprising a packaging material having a bulk layer and being formed into a three-dimensional container by folding packaging material along predefined crease lines thus forming a fracture along crease lines, wherein at least one of fractures forms a hinge mechanism having a single axis of rotation.

2 . A package according to claim 1 , wherein the width of the fracture forming the hinge mechanism is less than two times the thickness of the packaging material, calculated as an average of at least 20 different measurements.

3 . The package according to claim 1 , wherein the bulk layer is a fibrous layer.

4 . The packaging material according to claim 1 , wherein the bulk is a fibrous layer having a density higher than 300 kg/m3 and a bending stiffness index of from 6.0 to 24.0 Nm6/kg3, according to method ISO 2493-1 and SCAN-P 29:95 (equivalently 0.5 to 2.0 Nm7/kg3).

5 . The package according to claim 1 , wherein the crease lines have a reduced thickness of the imprinted or embossed packaging material, compared to uncreased material, of from about 5% to about 25% such as from about 10 to about 25%.

6 . The package according to claim 1 , wherein each crease line to facilitate one folding operation has only one single fracture initiation line.

7 . The package according to claim 1 , further comprising a closed bottom end being folded along at least one crease line for forming a hinge mechanism having a single axis of rotation.

8 . The package according to claim 1 , further comprising a plurality of corners, wherein at least one of corners is arranged at an area in which two or more crease lines substantially intersect, prior to folding.

9 . The package according to claim 8 , wherein at least one of crease lines intersecting at the area when folded forms a fracture acting as a hinge mechanism having a single axis of rotation.

10 . The package according to claim 9 , wherein all of crease lines intersecting at the area when folded forms a fracture acting as a hinge mechanism having a single axis of rotation.

11 . The package according to claim 8 , wherein the thickness of the fracture forming the hinge mechanism at the area in which two or more crease lines intersects is substantially equal to the thickness of the fracture hinge mechanism at another location.

12 . The package according to claim 1 , wherein the fracture forming the hinge mechanism having a single axis of rotation extends along the entire crease line.

13 . The package according to claim 1 , wherein the fracture forming the hinge mechanism comprises a connection between a first side of the packaging material and a second side of the packaging material, wherein the thickness of the fracture forming the hinge mechanism is greater than the thickness of the packaging material at the first or second sides.

14 . The package according to claim 13 , wherein the fracture forming the hinge mechanism is symmetric relative the first side and the second side.

15 . The package according to claim 13 , wherein the fracture forming the hinge mechanism is non-symmetric relative the first side and the second side.

16 . The package according to claim 1 , wherein the packaging material comprises a laminate having a layer of bulk material being covered by plastic coatings on each side of the layer of bulk material.

17 . The package according to claim 16 , wherein the laminate further comprises a barrier layer for preventing diffusion of oxygen through the laminate.

18 . The package according to claim 17 , wherein the barrier layer comprises aluminum.

19 . The package according to claim 1 , made from a continuous web of the packaging material.

20 . The packaging material having the characteristics according to claim 1 , upon folding to 90 degrees.
