CA 2259690

A packaging unit includes an article supporting surface (1) which is joined to a cupped lid (2, 3) on two mutually opposing side-edges via respective, generally parallel fold lines (4, 5). The article supporting surface (1) and the lids (2, 3) together form an article enclosure. A unit closure means (22, 32) is provided for holding the packaging unit in a closed state. The two lids (2, 3) have end-walls (21, 31) and the end-walls at at least one end of the packaging unit lie adjacent one another and essentially in contact with each other when the packaging unit is closed. The unit closure means includes a groove (32) in one end-wall (31) of one lid (3), and a rib (22) in that end- wall (21) of the other lid (2) that lies adjacent the groove-containing end- wall when the packaging unit is closed, such that the rib (22) engages the groove (32) in the closed state of the packaging unit, and the rib (22) and groove (32) respectively extend from the free edge (23, 33) of their respective end-walls and have a generally straight longitudinal extension.

L'invention concerne une unité d'emballage comprenant une surface (1) supportant un article et qui est associée à un couvercle en forme de coupe (2, 3) sur deux bords latéraux opposés par des lignes de pliage généralement parallèles (4, 5). La surface (1) supportant l'article et les couvercles (2, 3) forment une enceinte. Un moyen de fermeture (22, 32) permet de maintenir l'unité d'emballage à l'état fermé. Les deux couvercles (2, 3) possèdent des parois terminales (21, 31) et les parois terminales situées au niveau d'au moins une extrémité de l'unité d'emballage sont adjacentes et essentiellement en contact l'une avec l'autre lorsque l'unité d'emballage est fermée. Le moyen de fermeture de l'unité comporte une rainure (32) dans une paroi terminale (31) d'un couvercle (3), et une nervure (22) dans la paroi terminale (21) de l'autre couvercle (2) qui est adjacent à la paroi terminale renfermant la rainure lorsque l'unité d'emballage est fermée de sorte que la nervure (22) s'engage dans la rainure (32) à l'état fermé de l'unité d'emballage. La nervure (22) et la rainure (32) s'étendent respectivement du bord libre (23, 33) de leurs parois terminales respectives et ont une extension longitudinale généralement droite.
