Abstract (en)

A rigid sheet blank (10) including a first section and an adjacent second section configured to be bent relative to the first section. A seam (30) separates the first section from the second section to facilitate bending of the first and second sections relative to one another. The seam (30) defines a seam axis (32) and includes at least one cut (34) through a material of the rigid sheet blank (10). Each of the at least one cut (34) includes a main portion (40) that is elongated such as to extend along a direction parallel to the seam axis (32), a first extension (42) extending from a first end (46) of the main portion (40) and being generally perpendicular to the main portion (40), and a second extension (44) extending from a second end (48) of the main portion (40) and being generally perpendicular to the main portion (40). The first and second extensions (42, 44) extend on a same side of the main portion (40).
