Billiard ball and method for manufacturing same

Abstract

The present invention relates to a billiard ball, comprising: a main body, the outer surface of which has at least one design groove; a designed member which is arranged in the design groove and which has a design; and a transparent resin which fills the design groove, thereby continuously showing an advertisement design, which has been formed on the billiard ball, during a game of billiards, thus achieving maximized advertising effects.

1 . A billiard ball comprising a main body, the outer surface of which has at least one design groove; a designed member which is arranged in the design groove and which has a design; and a transparent resin which fills the design groove. 
     
     
         2 . The billiard ball according to  claim 1 , wherein the designed member is provided in a bottom surface of the design groove. 
     
     
         3 . The billiard ball according to  claim 1 , wherein the designed member comprises a first design portion that is provided in a side of the design groove and a second design portion which is provided in a bottom surface of the design groove. 
     
     
         4 . The billiard ball according to  claim 1 , wherein the designed member comprises Korean paper. 
     
     
         5 . The billiard ball according to  claim 1 , wherein the design groove is 0.5 to 3 mm in depth. 
     
     
         6 . The billiard ball according to  claim 1 , wherein the transparent resin comprises the same material as the resin for forming the main body. 
     
     
         7 . A manufacturing method for a billiard ball, the method comprising: forming a design groove in a main body, inserting a designed member into the design groove, filling the design groove with resin, curing the resin and trimming a surface of the resin filling the design groove to prevent any step from the surface of the main body. 
     
     
         8 . A billiard ball which comprises a main body in which at least one through hole is formed and passes through a center and a design bar which is provided in the through hole, and has a design printed in both ends. 
     
     
         9 . The billiard ball according to  claim 8 , wherein the design bar is formed in the same material as that of the main body. 
     
     
         10 . The billiard ball according to  claim 8 , wherein the at least one design bar comprises a first bar member which passes through a center of the main body and is arranged vertically, a second bar member which passes through a center of the main body and is arranged to the left and right horizontally and a third bar member which passes through a center of the main body and is arranged horizontally in forward and backward directions. 
     
     
         11 . A manufacturing method for a billiard ball, the method comprising:
 preparing a design bar which has a design in both ends; and   placing the design bar so that both ends of the design bar are provided in an edge of an internal space of the mold; and injecting resin to the mold to form a main body which surrounds the design bar.   
     
     
         12 . The method according to  claim 11 , wherein the design bar has the same melting point as that of the main body or has a higher melting point than the main body. 
     
     
         13 . The method according to  claim 11 , further comprising thermal-treating a surface of the main body.
