The packaging comprises a bottom (1) and four side walls (2,3,4,5). Two opposite walls (4,5) have side flaps (10) which are fixed to the end of adjacent walls. Grooves in the corrugated cardboard extend vertically on the flaps and walls. The walls with the flaps are extended at their upper edge by a double folded down tab (13) which is fixed internally. This tab extends to the top of the walls. The lower part of the flaps' internal faces are fixed to the external face of the adjacent walls. The upper edge of the flaps have an extension in the shape of an ear (15) which is folded down internally toward the flap and is fixed to the flap upper part.
