| 1 | Long life, low air permeable pressurized articles such as play balls | US438674 | 1995-05-10 | US5593157A | 1997-01-14 | William J. Koros; I. G. Hargis; Richard A. Olson; Jason S. Harris |
| Low air permeable, pressurized articles such as play balls, e.g., a tennis ball, have a thin barrier layer formed on the vulcanized rubber core. The barrier layer is chemically bonded to the internal and/or external surface of the core, e.g., by the reaction of a Lewis acid, e.g., sulfur trioxide, with the core rubber. The thin barrier layer permits the tennis ball to be flexible and have good rebound life and yet extends the play life thereof before ball rebound or softness changes to undesired levels. | ||||||
| 2 | Elastic spheroid structure | US15379644 | 2016-12-15 | US09855468B1 | 2018-01-02 | Sheng-Mou Huang |
| An elastic spheroid structure includes a hollow elastic spheroid body having an elastic spheroid shell, a receiving space formed inside the elastic spheroid shell, and a through opening passing through the elastic spheroid shell and being in air communication with the receiving space. The through opening has a first predetermined shape, the through opening has a first middle portion and a plurality of first extending portions extended outwardly from the first middle portion, and the first predetermined shape of the through opening is formed by connecting the first middle portion and the first extending portions. The elastic spheroid structure further includes a solid elastic cover body disposed inside the through opening of the hollow elastic spheroid body and a connection layer disposed inside the through opening and connected between the elastic spheroid shell and the solid elastic cover body. | ||||||

| A method for making a bouncing ball with columns is provided. The method includes the steps of: providing a mold comprising an upper mold and a lower mold each having a plurality of column holes extending outward from an inner surface thereof and being communicated with an outside of the mold, wherein an air-permeable and liquid non-permeable material is coated on an outer surface of the mold and thus covers the column holes; filling a ball material into the upper mold or the lower mold, coupling the upper mold and the lower mold together, and rotating the mold to coat the ball material onto the inner surface of the mold and further be filled into the column holes; and opening the upper mold and the lower mold to take the bouncing ball out of the mold after the ball material is solidified. | ||||||

| [Object] To provide a method for easily increasing the internal pressure of a hollow ball in a practical time. [Solution] A method for increasing the internal pressure of a hollow ball according to the present invention includes the steps of (1) putting a hollow ball 18 including an outer shell and a space surrounded by the outer shell, into a housing portion 4; (2) filling the housing portion 4 with a gas which is more excellent in permeability relative to the outer shell than oxygen gas and nitrogen gas; and (3) causing the gas to pass through the outer shell. When the outer shell contains natural rubber, preferably, in the step (2), the housing portion is filled with a gas having a permeability coefficient of 20 × 10 -17 m 4 /(N€¢s) at 25°C for the natural rubber. Preferably, in the step (2), the housing portion is filled with carbon dioxide gas. | ||||||

| The invention relates to a pressurised tennis ball with a wall consisting essentially of a natural rubber mix. In order to reduce the natural diffusion of the pressurised air inside the ball from the raw ball core, its wall has a thin diffusion blocking layer of a plastic or rubber, the permeability of which to N2 or O2 is lower than that of the natural rubber mixture of the wall. | ||||||
