Liquid-filled golf ball with preferential internal structures
A golf ball having a spherical shell with a plurality of internal structures is disclosed herein. A fluid material is disposed within the spherical shell. The plurality of internal structures influence the spin decay of the golf ball.
1. A golf ball comprising:
a core comprising
a spherical shell having a shell wall defining an interior chamber,
a plurality of internal structures partitioning the interior chamber of the spherical shell into a plurality of sub-chambers, wherein each of the plurality of sub-chambers is in flow communication with another sub-chamber, wherein each of the plurality of sub-chambers has a volume ranging from ten percent to fifty percent of the volume of the interior chamber, wherein the plurality of internal structures comprises from two to ten internal structures, and
a fluid material within the spherical shell; and
a cover.
2. The golf ball according to claim 1 wherein each of the plurality of internal structures has a thickness ranging from 0.010 inch to 0.250 inch.
3. The golf ball according to claim 1 wherein each of the plurality of internal structures has a thickness ranging from 0.035 inch to 0.150 inch.
4. The golf ball according to claim 1 wherein each of the plurality of internal structures has a thickness ranging from 0.050 inch to 0.100 inch.
5. The golf ball according to claim 1 wherein the fluid material is selected from the group consisting of corn syrup, alcohol, water, propylene, glycol and mineral oil.
6. The golf ball according to claim 1 wherein the fluid material is glycerine.
7. The golf ball according to claim 1 wherein the spherical shell is composed of a material selected from the group consisting of vinyl resins, polyolefins, polyurethanes, polyamides, acrylic resins, thermoplastic rubbers, polyphenylene oxides, thermoplastic polyesters, polycarbonates, and blends thereof.
