For example, when an aperture in a first panel is“in registry with” a second aperture in a second panel that is placed in an overlapping arrangement with the first panel, an edge of the aperture may extend along at least a portion of an edge of the second aperture and may be aligned, in the direction of the thickness of the first and second panels, with the second aperture.

Abstract

Des aspects de l'invention concernent un agencement de réception d'article par le fond, un carton pour emballer une pluralité d'articles et une découpe pour former le carton. Le carton comprend une pluralité de parois comprenant : une paroi supérieure, une première paroi latérale, une seconde paroi latérale et une première paroi de base reliée de manière articulée à la première paroi latérale par une première ligne de pliage. Le carton comprend une ouverture de talon (A3) pour recevoir une partie de talon d'un article. L'ouverture de talon est frappée à partir d'au moins la première paroi latérale (20). L'ouverture de talon comprend au moins une partie étendue sous la forme d'un évidement (R3). L'évidement comprend une extrémité proximale qui s'ouvre vers le périmètre de l'ouverture de talon. L'ouverture de talon peut être de forme générale circulaire. L'ouverture de talon comprend un centre (C).
