摘要： The ball retrieval and storage device includes a container having a hollow interior for storing a substantial number of tennis balls. At least a portion of the container bottom is formed by one or more movable rod members which are movable to allow the balls to enter through the bottom of the container. A user can retrieve a ball lying on the ground by forcing the bottom of the container down over the top of the ball. The ball engages the movable rod member and moves it slightly upwardly which allows the ball to enter the container as the container is progressively forced down over the top of the ball compressing the ball. The movable rod members are formed of a material having an elastic memory such that for use over time, the movable rod members will not permanently deform so as to decrease the efficacy of the ball retrieval and storage device.
