Abstract

A tennis ball storage container is disclosed of the type wherein the balls located inside the container are maintained in a compressed air surrounding in order to prevent microscopic penetration of compressed air from inside the ball during the storage. The container comprises a cylindric storage container and a cylindric lid arranged to place over the container to close same. Sealing means are arranged on the container and on the lid which are effective to maintain a generally air tight sealing engagement between the container and the lid during the operation of placing the lid over said container. The sealing means prevents air present in the space defined by the container and the lid as the lid is being placed over the container. The sealing means prevents air present in the space defined by the container and the lid as the lid is being placed over the container. The volume defined by the inside of the lid amounts to at least two thirds of the volume defined by the container.
