A hollow moulded article such as a ball of the kind used in play areas where children jump on and swim through a volume of the balls. During moulding, date coding is impressed on the ball is in a way which enables the older balls to be identified and replaced when necessary. The date coding is provided in two ways, one is to provide an adjustable pin within a part of the mould cavity, and the other is to provide indicia whose positions can be changed by rotation of the air venting plug within the mould. |

©7 An object of the present invention is to obtain a tennis ball and a core for tennis ball which keeps high values within the ITF standard and besides has excellent durability. That is, the present invention provides a core for tennis ball obtained by vulcanizing a rubber composition containing, in its whole rubber component, 5 to 40 weight % of a 1,2-bonds containing polybutadiene and 60 to 95 weight % of a natural rubber and/or high cis-polybutadiene containing not less than 90% of cis 1,4-bonds, and tennis balls obtained therefrom. |

The invention relates to playballs, e.g. tennis balls, having a core pressurised with a low permeability gas, e.g. sulphur hexafluoride. Use of such gases can cause the ball to emit a pinging noise on bouncing. The invention provides a core (1) pressurised with gas of low permeability, the internal wall surface (3) of core (1) being profiled by a multiplicity of depressions or protuberances (4), the outer wall surface (2) of the core being smooth. The profiling is preferably in the form of dimples or pimples of circular plan view. |

| A puck includes a main body having a first portion and a second portion securely attached to form a generally cylindrical shape with an internal cavity. One or more energy absorbing components are positioned within the internal cavity. A weight component is positioned adjacent to the one or more energy absorbing components within the internal cavity. The weight component is sized to move in a vertical direction and deform the one or more energy absorbing components within the internal cavity in response to movement of the puck. | ||||||

| 316 | Deformable Toy | US15885552 | 2018-01-31 | US20180221717A1 | 2018-08-09 | John Hinnen, III |
| Embodiments of the present invention provide a toy deformable to several structural configurations. The toy includes two endcaps connected by a plurality of pliable ribs. The toy may be deformed into a low-profile configuration by pressing the endcaps together, the ribs bending outward to accommodate the deformation. The toy may be deformed into a high-profile configuration by squeezing the ribs together, the endcaps being pushed apart to accommodate the deformation. While pressure is not applied to the toy, the toy may enter a non-deformed configuration wherein the ribs and the toy as a whole take on a substantially spherical form. A retention device may also be utilized to confine the toy to a specific configuration. | ||||||
| 317 | SYSTEM AND METHOD FOR PRODUCING TOY BALLS FOR PETS | US15594188 | 2017-05-12 | US20180153139A1 | 2018-06-07 | Vung Van Nguyen |
| The invention relates to the method of producing toy balls for pets, including: manufacturing distorted sphere balls with an opening in the distorted area using injection molding; sealing the opening of the distorted sphere balls to form uni-body sphere-shaped balls. The material used in the production of these toys can be rubber, thermoplastic elastomers, or thermoplastic rubber. This method allows to manufacture toy balls with no detached parts in the case of broken joints when the balls are chewed or torn apart by the pets. Thus, the invention can help to keep the pets from endangering themselves by swallowing detached parts of pet toy balls. | ||||||

| An apparatus is provided, which includes a plurality of elongated strands having joinder regions uniting adjacent strands at a distance along a length of an outer perimeter of the elongated strands, the elongate strands being configured to couple together for a distance along their lengths. The elongated strands form a surface of a mesh when the joinder regions are coupled. The apparatus may further include a manducable protrusion coupled to the mesh and extending a distance away from an exterior surface of the mesh. | ||||||

| A sports ball for use in baseball-type games includes a hollow, substantially spherical plastic ball that has a plurality of substantially planar, intersecting regions covering an outer surface thereof. Preferably the ball also has a weight that is substantially less than a weight of a regulation baseball, for enhancing safety in use. The sports system further includes a bat for use with the ball, or with any similar ball, preferably a plastic ball. The bat is a hollow, elongated member that has a handle portion adjacent a bottom end and a barrel portion between the handle portion and a top end. The bat further has a sheath surrounding at least a portion of the barrel portion. The sheath has a coefficient of friction higher than a coefficient of friction of a surface of the barrel portion, for imparting “traction” to a struck ball. | ||||||
