ABSTRACT:
A packing box, in particular for pastries or cakes, is prepared from a cut-out and grooved blank.
The box is characterized in that: each flap (201-206; 401-404) is formed from a lower part (201A-206A; 401A-404A) and a tab (201B-206B; 401B-404B) and each lower part (201A-206A; 401A-406A) is bordered over at least part of its length and on at least one of its sides by a strengthening strip (201E, 201F-206E, 206F, 401E-401F) connected to the base by a fold line. The homologous strengthening strips of the two adjacent flaps are joined by a fold line (300, 501, 502, 503, 504) and when the flaps are raised, the two strengthening strips project into the space of the box and approach the fold lines so as to form a ridge between the two flaps.
The invention relates to cardboard boxes.
