A container (1, 1', 28) has a pressure vessel for regenerating and storing tennis balls (21, 21') under a positive gas pressure, preferably a positive air pressure. The container has a bottom (3, 20, 35) and a pressure-tight lid (3', 4, 31, 31') with an inlet valve (24, 24') and a gas pump (8, 8', 3

A container (1, 1', 28) has a pressure vessel for regenerating and storing tennis balls (21, 21') under a positive gas pressure, preferably a positive air pressure. The container has a bottom (3, 20, 35) and a pressure-tight lid (3', 4, 31, 31') with an inlet valve (24, 24') and a gas pump (8, 8', 34) linkable thereto. The gas pump (8) is constructively integrated inside the pressure vessel (2, 30, 30') or the container (1, 1', 28). A removable receptacle (12) made of several mutually detachable parts (13, 14) is inserted into the pressure vessel (2). The receptacle contains mutually separated recesses (15, 16) having substantially the size of tennis balls (21, 21') and interconnected by means of the inlet valve (24, 24') in such a way that gas can flow from one recess into another recess. The recesses (15, 16) are located within the parts (13, 14) that constitute the receptacle (12) and which make up chambers (15, 16) for tennis balls when the molds are aligned and assembled. An positive pressure may be applied on the tennis balls (21, 21') disposed in the chambers (15, 16) by means of the gas pump (8, 8'). A pressure relief valve (7, 7') and an outlet valve (6, 6') are integrated in the lid (3, 3') of the container and are in communication with the pressure vessel (2, 2') inside the container.
