A nesting packaging container has first and second preformed, rigid U-shaped members (12,14) each having a U-shaped cross-section. The U-shaped members are configured to fit into one another to form a rectangular cross-section container. Each of the U-shaped members has a base wall (15) and opposing side walls (17), the intersection of the base and side walls being rigid. The base wall has a thickness. A narrow slit (16) is formed in the base wall, extending longitudinally along the base wall and formed from an inner surface (18) of the wall into the thickness of the base wall. The base wall is foldable along the slit (16) so as to form a generally W-configuration cross-section. The thus W-configuration, U-shaped members are nestable with each other. When the U-shaped member is unfolded to the U-shaped cross-section, the opposing surfaces formed by the slit abut one another to maintain the crate in the U-shaped cross-section.

L'invention concerne un contenant de conditionnement emboîtable ayant un premier et un deuxième éléments rigides et préfabriqués en U (12, 14) ayant chacun une coupe en U. Les éléments en U sont configurés pour s'adapter l'un dans l'autre pour former un contenant de coupe rectangulaire. Chacun des éléments en U a une paroi de base (15) et des parois latérales opposées (17), l'intersection de la paroi de base et des parois latérales étant rigide. La paroi de base a une épaisseur. Une fente étroite (16) est formée dans la paroi de base, s'étendant dans le sens longitudinal le long de la paroi de base et formée en provenance d'une surface intérieure (18) de la paroi jusque dans l'épaisseur de la paroi de base. La paroi de base est pliable le long de la fente (16) de manière à former une coupe à configuration généralement en W. Les éléments en U ainsi à configuration en W sont emboîtables les uns par rapport aux autres. Quand l'élément en U est déplié en coupe en U, les surfaces opposées formées par la fente viennent buter l'une contre l'autre pour maintenir la caisse en coupe en U.
