Patent ID: 7066840

Claim:
A golf ball, comprising: a ball cover, having a S-shaped seam continuously formed on an outer surface of said ball cover and comprising a first hemispheric cup and a second hemispheric cup attached to said first hemispheric cup edge to edge to form a hollow spheroid; and a solid ball core covered by said ball cover; wherein said first hemispheric cup has two identical first semi-conical engagement edges symmetrically outwardly projecting at two sides thereof and two identical first semi-conical connection edges inwardly projecting between said two first semi-conical engagement edges, wherein said two first semi-conical engagement edges are symmetrically and continuously extended between said two first semi-conical connection edges so as to form a continuous first joint edge for said first hemispheric cup; wherein the second hemispheric cup has two identical second semi-conical engagement edges symmetrically outwardly projecting at two sides thereof and two identical second semi-conical connection edges inwardly projecting between said second first semi-conical engagement edge, wherein said two second semi-conical engagement edges are symmetrically and continuously extended between said two second semi-conical connection edges so as to form a continuous second joint edge for said second hemispheric cup; wherein a cone height of each of said first and second semi-conical engagement edges is equal to a cone height of each of said first and second semi-conical connection edges, and a size and shape of said first hemispheric cup and the second hemispheric cup are identical and symmetrical, wherein said two second semi-conical engagement edges are fittingly engaged with said two first semi-conical connection edges respectively while said two second semi-conical connection edges are fittingly engaged with said two first semi-conical engagement edges respectively, so as to integrally unite said first hemispheric cup and said second hemispheric cup together to form said ball covert; wherein said S-shaped seam are formed along a connection between said two second semi-conical engagement edges and said two first semi-conical connection edges respectively and a connection between said two second semi-conical connection edges and said two first semi-conical engagement edges respectively.
