Abstract

La présente invention concerne un carton d'emballage d'objets pouvant être séparé en de plus petites unités. Le carton comprend une paroi supérieure présentant une ligne de rupture, une première séries de panneaux primaires reliés entre eux s'articulant sur la première partie panneau supérieur pour délimiter une première structure tubulaire, et une seconde série de panneaux primaires reliés entre eux s'articulant sur la seconde partie panneau supérieur pour délimiter une seconde structure tubulaire. Les première et seconde séries comprennent respectivement des premier et second panneaux inférieurs. Le carton comprend en outre des premier et second rabats d'extrémité inférieurs s'articulant respectivement sur les premier et second panneaux inférieurs. Les premier et second rabats d'extrémité inférieurs ne sont pas directement corps l'un avec l'autre mais sont reliés l'un à l'autre pas un élément de liaison fixé selon un agencement de contact facial à au moins un des premier et second rabats d'extrémité inférieurs.
