Technical Field

The invention relates to the technical field of toys, in particular to a soft ball.

Background

Balls are one of the toys and appliances popular with both children and the general public. In the prior art, common ball articles are made of rubber or leather materials, and mainly are filled with gas or foam materials. Because the surface layer is hard, the children are easy to hit the face or other parts during sports or recreational activities, and especially, the children are easy to be hurt.

In addition, although the soft ball made of soft material provided by the prior art has certain safety and interest, the soft ball provided by the prior art is formed by reacting the same material in a mold or is coated with other materials on the surface, and the soft ball is separated from the soft material in the mold, so that the surface is easy to tear. In addition, the soft ball cannot simultaneously have multiple functions of long service life, safety guarantee, prompt by sounding at any time and strong interest in the entertainment process.
