SOLUTION: A container for both collecting and storing tennis balls is provided with a passing ring 5 with a narrow diameter, where a tennis ball shrunk by pressing force applied from the above can pass but the tennis ball released from pressing force and restoring elasticity after the passage of the tennis ball hardly falls by its own weight, on a bottom part 4 or a top part 2 of the container 1 for storing tennis balls. The size of the narrow diameter is 92-98% of the diameter of a container storing the passing ring body. COPYRIGHT: (C)2003,JPO
