A box made from sheet materials such as corrugated cardboard two sides, two ends connected to the sides at foldable corners and each with a central fold line and a bottom connected to the sides at foldable corners but not connected to the ends. A center partition running from one end of the box to the other is hingedly connected to the ends and is not connected to the bottom. The bottom has a central fold, enabling it to fold away from the partition when the ends are folded about the side corners in the same direction, the ends folding in the middle relative to the partition, to collapse the box. The partition is made from two panels which are attached back-to-back to one another and each panel has end flaps at each end which make up the ends of the box. The end flaps have their ends attached to flaps of the side walls of the box. In one embodiment, a center closing lid is provided. In another embodiment, no lid is provided and an upstanding tab on the center partition fits into a corresponding slot in the bottom of the box for stacking the boxes in registration with one another. In another embodiment, a handle hole is cut out of the center partition to provide a central handle for carrying the container
In a box made of foldable sheet material, said box having two sides, two ends connecting the sides at corners between said sides and ends, a bottom, a center partition running from one end to the other end of the box, and the bottom connected to the sides of the box, the improvement wherein the bottom and ends each have a central fold, the bottom is unconnected to the partition and is unconnected to the ends and wherein the partition is hingedly connected to the ends, the sides and ends are hingedly connected to one another and the bottom is hingedly connected to the sides so that the sides can be collapsed toward the partition by folding both ends relative to the sides in the same direction about the corners which connect the sides to the ends and folding said bottom relative to the sides by said bottom folding about said central fold line so as to move away from said partition.
