Title
(DE) VERSTÄRKTER BEHÄLTER AUS KARTON
(EN) IMPROVEMENT TO REINFORCED CARDBOARD TRAYS
(FR) PERFECTIONNEMENT AUX PLATEAUX RENFORCES EN CARTON
Abstract
(EN)
A reinforced tray produced by erecting a single suitably cut and scored cardboard blank. The tray includes a bottom wall (2) surrounded by four side walls (3, 4) of which at least one is provided, at its upper edge, with an extension (10) folded down to form a lining and reinforcing element over at least part of the height of said wall. The lining extension (10) comprises a projecting portion (32) intermediate the side ends thereof for use as a stacking reinforcement and/or supporting member. Said projecting portion consists of a flap cut out of said extension (10) and connected thereto along a fold line (21). The flap is provided with inner parallel fold lines that divide it into at least three sections enabling it to be erected and held in shape by securing one of said sections (27) to the side wall (4) that includes said lining extension (10).

(FR)
Le plateau renforcé est obtenu par mise en volume d'un flan unique de carton convenablement découpé et rainé. Ce plateau comprend un fond (2) bordé par quatre parois latérales (3, 4) dont au moins une est munie, au niveau de sa bordure supérieure, d'un prolongement (10) rabattu pour former un élément de doublage et de renfort sur au moins une partie de sa hauteur. Conformément à l'invention, le prolongement de doublage (10) comporte, entre ses extrémités latérales, au moins un élément en saillie (32) servant d'organe de renfort et/ou de support pour le gerbage. Cet élément en saillie est formé à partir d'un volet découpé dans ledit prolongement (10) et attenant à ce dernier par une ligne de pliage (21). Ce volet est muni de lignes de pliage internes, parallèles, qui le divisent en au moins trois tronçons pour permettre sa mise en volume et sa tenue par solidarisation de l'un desdits tronçons (27) avec la paroi latérale (4) qui porte le prolongement de doublage (10).
