CA 2203247

The cardboard is configured from a die-cut base sheet having side and front walls with side flaps. It comprises both reinforcement front walls (5) which are independent from the base sheet (1), and which are backed to the side walls. The reinforcement front walls (5) are comprised of a central sheet (6) divided at its sides by three folding lines which define an inner sector (7), an outer sector (8) and a flap (9). The inner sector (7) and the outer sector (8) configure in the trussing of the reinforcement front walll (5) a prismatic portion which provides for the resistance to stacking. Supports or reinforcement columns (19) are optionally provided, which match in length with the height of the cavities (20) of the prismatic portions.

La présente invention porte sur un emballage de carton, formé à partir d'une feuille de base découpée à l'emporte-pièce, ayant des parois latérales et frontales munies de rabats latéraux. Les deux parois frontales de renfort (5) sont indépendantes de la feuille de base (1) et sont adossées aux parois latérales. Les parois frontales de renfort (5) sont composées d'une feuille centrale (6) dont les côtés sont traversés de trois lignes de pliage définissant une section interne (7), une section externe (8) et un rabat (9). La section interne (7) et la section externe (8) forment, dans le renforcement de la paroi frontale (5), une portion en forme de prisme qui assure la résistance de l'emballage à l'empilage. Des supports ou colonnes de renfort (19), fournis en option, sont de longueur correspondant à la hauteur des cavités (20) des portions en prisme.
