Blank for assembling a device for packaging at least one windscreen wiper

A blank for assembling a packaging device for packaging at least one windscreen wiper, said blank being of elongate shape and comprising:

• at least two adjacent longitudinal areas articulated to one another via a longitudinal folding line, each longitudinal area forming a longitudinal face of the packaging device, at least one of the longitudinal areas being further articulated at each of two longitudinal ends to an end area, via a transverse folding line, each end area being adapted to form a substantially transverse end face of the packaging device;
• and
• at one of the two longitudinal ends is provided with longitudinal shock absorbing means comprising a slot,
• wherein the slot is situated at the level of the longitudinal folding line and extends longitudinally from the at one of the two longitudinal ends towards the other of the two longitudinal ends to a point spaced longitudinally from the transverse folding line,
• wherein the slot extends from the at least one longitudinal end of the blank along the longitudinal folding line and beyond a transverse junction plane substantially orthogonal to the longitudinal folding line and passing substantially through transverse ends of the transverse folding line, and
• wherein, when each end area is folded along each transverse folding line to form the transverse end face, the slot extends beyond the transverse junction plane to the point spaced longitudinally from the transverse folding line to form the longitudinal shock absorbing means.
