Abstract

A transport package including a compressible packaging and a packing configuration, the packing configuration including at least three individual stacks of absorbent tissue paper material, and the packaging maintaining said individual stacks in the packing configuration, the transport package forming a rectangular parallelepiped delimited by six outer surfaces, defining three transport package extensions extending along three perpendicular dimensions in space defining a length, a width, and a height of the transport package. A relative deformation of the transport package is defined for each of the three dimensions, being the relative shortening of the transport package extension along a selected dimension when the entire transport package is compressed with a deformation pressure of 15 kPa between two outer surfaces and along the selected dimension, wherein, for said transport package, the relative deformation along at least two out of the three dimensions is less than 10%.

First claim

The invention claimed is:

1. A transport package comprising a compressible packaging and a packing configuration,
the compressible packaging being a flexible material,
the packing configuration comprising at least three individual stacks of absorbent tissue paper material, wherein each stack of the packing configuration is provided in an individual package of a stack and a stack packaging, wherein the stack packaging is of a flexible material, and said packing configuration consists of the individual packages,
the packaging maintaining said individual stacks in said packing configuration,
said transport package forming a rectangular parallelepiped delimited by six outer surfaces, defining three transport package extensions extending along three perpendicular dimensions in space defining a length, a width and a height of said transport package,
a relative deformation of said transport package being defined for each of said three dimensions, being the relative shortening of the transport package extension along a selected dimension when the entire transport package is compressed with a deformation pressure of 15 kPa between two outer surfaces and along the selected dimension,
wherein, for said transport package, the relative deformation along at least two out of said three dimensions is less than 10%, and wherein the absorbent tissue paper material of at least one of said individual stacks of said packing configuration contributes to limiting said relative deformation.

2. The transport package according to claim 1 , wherein the tissue paper material of at least 50% of said individual stacks in said packing configuration contributes to limiting said relative deformation.

3. The transport package according to claim 1 , wherein said relative deformation along said at least two out of said three dimensions is less than 5%.

4. The transport package according to claim 1 , wherein, a relative deformation of the transport package along a third dimension is defined by the relative shortening of the transport package extension along said third dimension when the entire transport package is compressed with a deformation pressure of 15 kPa between two outer surfaces and along said third dimension, said relative deformation being less than 15%.

5. The transport package according to claim 1 , wherein, for each relative deformation along a selected dimension, at a deformation pressure of 15 kPa, a maximum elongation is defined being the maximum relative lengthening of the transport package extensions perpendicular to said selected dimension along which the transport package is compressed at 15 kPa, said maximum elongation being less than 5%.

6. The transport package according to claim 1 , wherein said packaging is such that, when said transport package is compressed along a selected dimension with a deformation pressure of 15 kPa, the packaging is maintained in an intact condition.

7. The transport package according to claim 1 , wherein said packaging comprises disposable material.

8. The transport package according to claim 1 , wherein said packaging is collapsible.

9. The transport package according to claim 1 , wherein said packaging is non-collapsible.

10. The transport package according to claim 1 , wherein a relative deformation of said transport package as measured when the entire transport package is compressed with a deformation pressure of 25 kPa between two outer surfaces and along the selected dimension, is less than 10%, along at least two out of said three dimensions.

11. The transport package according to claim 1 , wherein said packing configuration forms a rectangular parallelepiped delimited by six outer surfaces, generally corresponding to said rectangular parallelepiped formed by said transport package.

12. The transport package according to claim 1 , wherein said stack packaging is collapsible.

13. The transport package according to claim 4 , wherein, in each individual stack, said absorbent tissue paper material forms panels having a stack length and a stack width, perpendicular to said stack length, said panels being piled on top of each other to form a stack height.

14. The transport package according to claim 13 , wherein, in said packing configuration of said transport package, at least two individual stacks in said transport package are arranged with their respective stack lengths extending in parallel to different transport package extensions.

15. The transport package according to claim 13 , wherein, in said packing configuration of said transport package, at least 50% of said individual stacks are arranged with their respective stack lengths extending in parallel to the same transport package extension.

16. The transport package according to claim 13 , wherein, in said packing configuration, less than 50% of the individual stacks are arranged with their respective stack lengths extending in parallel to one of said dimensions displaying said relative deformation.

17. The transport package according to claim 13 , wherein, in said packing configuration, less than 50% of said individual stacks are arranged with their respective stack lengths extending in parallel to said third dimension.

18. The transport package according to claim 13 , wherein, in said packing configuration, at least 50% of said individual stacks are arranged with their respective stack heights extending in parallel to said third extension.

19. The transport package according to claim 1 , wherein said absorbent tissue paper material comprises a dry crepe material, a structured tissue material, a wet crepe material, or a combination material comprising at least two of the afore-mentioned materials.

20. The transport package according to claim 1 , wherein said stacks have a stack density of at least 0.20 kg/dm3.

21. The transport package according to claim 1 , wherein said transport package has a packing density of at least 0.20 kg/dm3.

22. A method for forming a transport package according to claim 1 , said transport package comprising at least three individual stacks of absorbent tissue paper material, said method comprising:
selecting a compressible packaging,
arranging said individual stacks in a packing configuration, and
arranging said compressible packaging so as to maintain said packing configuration to form said transport package.
