CA 2141397

A tray-like, shallow carton (9) has angled corners and struts (34, 40) that reinforce the load bearing capacity of the carton. End closure flaps (20, 22, 24/25, 26/27) which become end walls of the carton have a pair of closure tabs (42) and sealing tabs (44) that cover and seal the angled corners of the carton (9). The carton (9) may be formed from a rectilinear blank (8) that contains all of the elements of the carton within the rectilinear perimeter of the blank (8). In another embodiment, a blank (208) and carton (209) have a corner structure which includes a tucking tab (248) lying between closure (242) and sealing (244) tabs. In the erected carton (209) the tucking tab (248) and closure tab (242) are pushed into the recess of each respective corner.

Boîte peu profonde (9) en forme de plateau, ayant des coins et des entretoises angulaires (34, 40) qui augmentent sa portance. Les languettes de fermeture d'extrémité (20, 22, 24/25, 26/27), qui deviennent les parois d'extrémité de la boîte, sont dotées d'une paire de pattes de fermeture (42) et de pattes de scellage (44) qui couvrent et scellent les coins angulaires de la boîte (9). Cette dernière (9) peut être formée à partir d'une pièce de carton rectilinéaire (8) dont le périmètre contient tous les élément de la boîte. Dans une autre version, la structure du coin de la pièce de carton (208) et de la boîte (209) est dotée d'une patte de pliage (248) située à plat entre les pattes de fermeture (42) et de scellage (44). Lorsque la boîte est formée (209), les pattes de pliage (248) et de fermeture (242) sont insérées dans les creux formés respectivement par chaque coin.
