Abstract

The container is cylindrical and is capable of holding three tennis balls. The container consists of an inner cylinder which is just big enough to hold the tennis balls. This cylinder fits into a base (2). The base has an 'O' ring at its top edge (4). The outside of the inne r cylinder still protruding has a square section thread on it. The cylinder is closed by means of the screw-on lid (11) which closes onto the 'O' ring (4), and two other 'O' rings (9) and (13). The volume of air trapped in the container is reduced to two thirds of its value when the cylinder is tightened down.
