Through the use of an internal support system integrated with the interior shell of a hollow ball, the concentration of impact stress to the ball's shell during game play is reduced through better dispersion and resistance of applied force, while also reinforcing the ball's shell at its weakest points, which are the holes, thus making it more resilient and thereby less susceptible to breakage. Enhanced fortification against impact stress applied during gameplay serves to increase the usable life of the ball.

A device for storing at least one game ball under pressure, the device having a container with a leak-tight cover and a casing arranged around, and at a distance from, the container, and a pump for pumping ambient air into the container. The pump can include an annular piston arranged between the container and the casing, a handle connected to the piston for moving the piston translationally along the container, a first non-return valve for admitting ambient air into a compression chamber between the casing and the container, and a second non-return valve, arranged between the compression chamber and an internal volume of the container, for transferring air from the compression chamber to the container.
