The present invention relates to sports balls. A sports ball comprises a surface layer comprising a plurality of panels. The sports ball further comprises a lattice structure extending below the surface layer, wherein the lattice structure comprises a plurality of lattice cells comprising radially extending elements. The lattice cells which are adjacent to the surface layer have at least one dimension which is smaller than an average diameter of the panels.

The present disclosure relates to the technical field of water playing toys, particularly to a toy water balloon, which comprises a flexible shell, a flexible cover and an elastic arm. The flexible shell limits a water storage cavity and an opening connects the water storage cavity and the external space of the flexible shell. The outer contour of the flexible cover is larger than that of the opening to seal the water storage cavity. It is only needed to make the toy water balloon deformation by using the opening to expose the water storage cavity. Which results in higher safety and lower production cost. Compared with the non-magnetic toy water balloon, the flexible cover will stick closely to the inner wall of the water storage cavity so that the toy water balloon disclosed in the present application has good sealing properties.

A throwable exploding water ball includes a main body and a sealing cover member. The main body is provided with at least one opening, and the opening is in communication with an inner cavity of the main body. The main body and the sealing cover member are both made of an elastic soft material. The sealing cover member is connected to the main body through a connecting member and seals the opening, so that the inner cavity of the main body is able to store water. When the main body and/or the sealing cover member are deformed by an impact, an openable and closeable opening is formed between the main body and the sealing cover member, so that the water in the inner cavity of the main body is splashed out from the openable and closeable opening through the opening.

Disclosed is a baseball with a luminous function, including a baseball body, an adjusting assembly, a luminous body assembly, and a battery. Latches are arranged on an inner side wall of an upper ball body; a bump is arranged between the latches; latch holes are formed in the inner wall of the ball body; a groove is formed between the latch holes; after the upper ball body and a lower ball body are closed, the latches are connected to the latch holes in an inserted manner and are fixed, so that the upper ball body and the lower ball body are fixed together, and the latches and the latch holes are fixed or separated, so that the upper ball body and the lower ball body are closed or opened; the adjusting assembly is arranged at a top of the baseball body; and an adjusting button adjust a luminous body.

A tennis ball may include a non-foamed thermoplastic core defining an internal volume, the core having an outer meltable surface. The core may include a thermoplastic material having a specific gravity of 0.86 to 1.38, a flexural modulus of 2.0 to 50.0 MPa, and a Shore D hardness of 10 to 70. The thickness of the thermoplastic material may be between 3.0 and 8.0 mm and configured to maintain dimensional stability at internal pressures of between zero and 15 psi. The tennis ball may further include a felt cover at least partially covering the core, wherein the tennis ball conforms to ITF and USTA size, weight, deformation and rebound requirements.

A set for playing a sport, designed for an exchange of shots between two players. The set includes: a ball; and a table having a playing surface longitudinally extending between opposite action edges, between which the players are caused to exchange shots with the ball. The playing surface has a curved longitudinal profile, between the action edges delimiting a concavity open above the table. The playing surface and the ball being configured to absorb bounces of the ball on the playing surface.
