Abstract

L'invention concerne une découpe d'emballage (2 ; 2' ; 2'' ; 2''') et un emballage (1 ; 1'') comprenant au moins une première ligne de pli (40) et une seconde ligne de pli (41) convergeant l'une vers l'autre, une première ligne imaginaire (42) comprend la première ligne de pli (40) et une seconde ligne imaginaire (43) comprend la seconde ligne de pli (41), la première ligne imaginaire (42) et la seconde ligne imaginaire (43) se croisant à un point d'intersection supérieur (44) respectif. Le point d'intersection supérieur (44) est éloigné d'une première section (37) d'une ligne de pli transversale (28) en considérant la découpe d'emballage (2, 2') ou d'un bord avant supérieur (8) en considérant l'emballage (1 ; 1'').
