  • Patent number: 10188512
    Abstract: The present invention's goal is to devise an apparatus (here-forth called ‘punch-ball’) made of a tension-reversible membrane that will assume a particular three-dimensional predetermined shape when under tension, apparatus that will border a central empty space, central space limited by the interior face of the membrane, and central space that will be in direct communication with the exterior space outside of the external face of the ‘punch-ball’ through orifices in the membrane (here-forth called ‘punches’), punches that will not decrease the ability of the membrane to exhibit a tension force. The punch-ball can be used freestanding or in connection with an object representing a confined space that will be abutting the exterior face of the punch-ball when the punch-ball is under tension.
