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. |
