ABSTRACT:
The structure includes a container having a bottom wall with slotted apertures having thin parallel side edge members through which tennis balls can be squeezed. At least one edge member of each aperture includes a roller to reduce the frictional resistance to the entry of the ball through the aperture. A support is provided for supporting the container with the bottom wall spaced above the supporting surface to prevent wear on the bottom wall.
