A handle structure for a carton (10) is formed within a panel (20) having opposing side edges and opposing end edges that intersect to form corners of the handle panel (20). A strap member (46, 44) is integrally conjoined with the handle panel (20) and extends between the end edges. Opposing strap edges are substantially disjoined from the handle panel (20). The strap member (44, 46) includes a substantially centrally disposed region wherein opposing central strap edge segments of the opposing strap edges are substantially parallel to and mediate the opposing side edges. A severance line (57) segment is disposed proximate each of the corners of the handle panel extending from a first end point proximate the centrally disposed region of the strap member (46, 44) such that when a force (F) that is substantially normal to a plane in which the handle panel lies is exerted upon the centrally disposed region, the strap member is flexed substantially outwardly of the plane from a biased position proximate the plane.

La présente invention concerne une structure de poignée destinée à un carton (10), formée à l'intérieur d'un panneau (20) comportant des bords latéraux opposés et des bords d'extrémité opposés se croisant pour former les coins du panneau de poignée (20), la structure de poignée. Un élément de liaison (46, 44) est intégralement relié au panneau de poignée (20) et dépasse entre les bords d'extrémité. Les bords de liaison opposés sont essentiellement disjoints du panneau de poignée (20). L'élément de liaison (44, 46) comprend une zone pratiquement centrale dans laquelle des segments de bords de liaison centraux opposés des bords de liaison opposés sont pratiquement parallèles aux bords latéraux opposés et se trouvent dans la partie médiane de ceux-ci. Un segment de ligne de séparation (57) se trouve à proximité de chacun des coins du panneau de poignée, en partant d'un premier point extrême à proximité de la zone centrale de l'élément de liaison (46, 44) de sorte que lorsqu'une force (F) essentiellement normale à un plan dans lequel se situent les panneaux de poignée s'exerce sur la zone centrale, l'élément de liaison se recourbe essentiellement vers l'extérieur du plan à partir d'une position de sollicitation à proximité du plan.
