Ball with improved structure

Abstract

The disclosed ball with improved structure of the present invention comprises a hollow bladder that can be inflated in to a ball-like shape, a reinforcement layer that is a layer of cloth having intensive pores and fixedly covering up to the outer surface of the bladder, a buffer layer that is made from foam and fixedly attached to the outer surface of the reinforcement layer, a cover layer that is a layer of cloth having intensive pores and fixedly attached to the outer surface of the buffer layer, and an external layer that fixedly covers up the outer surface of the cover layer and forms the appearance of the ball.

1 . A ball with improve structure comprising:
 a hollow bladder that can be inflated in to a ball-like shape,   a reinforcement layer that is a layer of cloth having intensive pores and fixedly covering up the outer surface of the bladder,   a buffer layer that is made from foam and fixedly attached to the outer surface of the reinforcement layer,   a cover layer that is a layer of cloth having intensive pores and fixedly attached to the outer surface of the buffer layer, and   an external layer that covers up the outer surface of the cover layer and forms the appearance of the ball.   
   
   
       2 . The ball of  claim 1 , wherein the buffer layer permeates into the intensive pores of the reinforcement layer. 
   
   
       3 . The ball of  claim 1 , wherein the cover layer is adhered to the outer surface of the buffer layer with adhesive. 
   
   
       4 . The ball of  claim 1 , wherein the external layer is adhered to the outer surface of the cover layer with adhesive. 
   
   
       5 . A ball with improved structure comprising a hollow bladder that can be inflated in to a ball-like shape and a reinforcement layer made through winding thread around the outer surface of the bladder with a winding machine, wherein the ball further comprises:
 a buffer layer that is made from foam and fixedly attached to the outer surface of the reinforcement layer,   a cover layer that is a layer of cloth having intensive pores and fixedly covering up the outer surface of the buffer layer, and   an external layer that fixedly covers up the outer surface of the cover layer and appears as the appearance of the ball.   
   
   
       6 . The ball of  claim 5 , wherein the cover layer is adhered to the outer surface of the buffer layer with adhesive. 
   
   
       7 . The ball of  claim 5 , wherein the external layer is adhered to the outer surface of the cover layer with adhesive.
