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.
A tennis ball storage container of the type wherein the balls located inside the container are maintained in an environment of compressed air, said container comprising a cylindrical storage means; a cylindrical lid arranged to be placed over said container to close same; two sealing means between said container and said lid arranged to effect and to maintain a generally air tight sealing engagement between the container and the lid during and upon the placing of said lid over the container, whereby air is substantially prevented from escaping from the space defined by the lid and by the container as the lid is being placed over the container to close same, the first sealing means being located near the top of said container and abutting said container and lid to maintain a seal as the lid is applied, and the second sealing means being located at the top of the container and abutting the lid when it is in complete engagement with the container, the volume of the inside of the cylindrical lid being generally equal to two thirds of that of the container, and wherein the base of the container is surrounded by a casing, the cylindrical lid is in threadable engagement with the container and further sealing means are provided between said casing and said lid to seal the lid against the casing.
