An inflatable sports ball is provided. The sports ball includes an interior bladder and a cover disposed about the interior bladder. The cover may include an outer substrate and an intermediate structure. The cover may further include an outer substrate surface, defined by the outer substrate, and a feature surface radially spaced apart from the outer substrate surface. Together the outer substrate surface and the feature surface cooperate to define an exterior surface of the cover. A mechanoluminescent material may be embedded in a portion of the cover. The mechanoluminescent material may be disposed at only one of the outer substrate surface and the feature surface, such that it is positioned to form a predetermined design on the cover. The mechanoluminescent material emits visible light in response to an externally-applied stress, such that the predetermined design illuminates when an external stress or mechanical stimulus is exerted upon the cover.

One or more aspects of the present disclosure are directed to bladders that incorporate a multi-layer optical film that impart a structural color to the bladder. The present disclosure is also directed to articles including the bladders having a multi-layer optical film, and methods for making articles and bladders having a multi-layer optical film.

The present disclosure provides a luminous ball and relates to the technical field of ball products. The luminous ball includes a bladder and an outer cover. The bladder is provided with a plurality of first fixing blocks therein. A side of each of the plurality of first fixing blocks is hinged with a telescopic device. Output ends of the telescopic devices are hinged with a gravity ball. The gravity ball is provided with a first rectangular slot therein. According to the present disclosure, one side of the first fixing block is hinged with a telescopic device, such that during the movement of the ball, the gravity ball can expand and retract, and the movement of the gravity ball is facilitated. Through the hinging the telescopic device with the first fixing block and the gravity ball, the movement of the gravity ball in any direction inside the bladder is facilitated. A stopper between a first rectangular slot and a retaining block can buffer a first circular opening to a certain extent during the movement of the gravity ball. The structure of this product greatly improves the water resistance, and the battery can be replaced.

A system and method for playing a pin based game with an impact resistant ball and process of forming an impact resistant ball are provided. The impact resistant ball has an increased resistance to damage caused to a ball by repeated impact with objects such as a game board and game pins thereby decreasing the frequency with which the ball must be replaced. The impact resistant ball also has utility to afford a larger segment of the population the ability to properly grip and throw the impact resistant ball by providing an increased length gripper able to accommodate a greater range of hand sizes. The impact resistant ball has further utility to automatically identify and transmit data including the impact of the ball with the game pins and ball metrics including speed, pressure and weight.
