Patent number: 10875705Abstract: 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%.Type: GrantFiled: December 18, 2015Date of Patent: December 29, 2020Assignee: ESSITY HYGIENE AND HEALTH AKTIEBOLAGInventors: Hans Wallenius, Fredrik Welander
