    • A thermoplastic multi-layer golf ball has a core center including a first thermoplastic material and having a diameter of from about 7 mm to about 20 mm and a surface Shore D hardness H1 of from about 30 to about 48; a core layer outward from the core center, the core layer including a second thermoplastic material and having a diameter of from about 25 mm to about 40 mm, a thickness of from about 7 mm to about 10 mm, a surface Shore D hardness H2 that is greater than H1, and a 10-130 kg compression deformation of from about 2.6 mm to about 3.2 mm; an inner cover layer outward from the core layer, the inner cover layer including a third thermoplastic material and having a surface Shore D hardness H3 of from about 55 to about 70; and an outer cover layer on the surface of the golf ball including a fourth thermoplastic material and having a surface Shore D hardness H4 of from about 44 to about 56 and a 10-130 kg compression deformation of from about 2.3 mm to about 3.2 mm. The difference between the specific gravity of the core center and the specific gravity of the core layer is not more than about 0.5 g/cm 3 .

    • A golf ball (5, 505, 605, 705, 805, 905, 1005) comprising an inner core (10, 610, 710, 910, 1010, 2010, 3010), an outer core (15, 20, 515, 520, 615, 620, 715, 720, 915, 920, 1015), and a cover (25, 625, 725, 925, 1025) is disclosed. The outer core (15, 20, 515, 520, 615, 620, 715, 720, 915, 920, 1015) surrounds the inner core, and the cover encases the cores. The inner core (10, 610, 710, 910, 1010, 2010, 3010) has a plurality of projections (35, 935, 1035, 2035, 3035, 4035) forming gaps (40, 840, 940, 1040, 2040, 3040, 4040) between each projection, where the free ends (45, 2038) of the projections form a spheroid-shaped surface. The inner core is formed of a first material and the outer core is formed of a second material. The outer core is non-wound, and the second material is disposed within the gaps (40, 840, 940, 1040, 2040, 3040, 4040) in the inner core so that the outer surface of the outer core is substantially spherical. The first and second materials have substantially different material properties. In one embodiment, the projections have enlarged free ends (45). In another embodiment, the projections (2035) taper from a base (2036) outward. In yet another embodiment, the maximum length (L) of each projection (3035, 4035) is greater than the maximum width (W).
    • 本发明涉及一种高尔夫球(5,505,605,705,805,905,1005),其包括内核(10,610,710,910,1010,2010,3010),外核(15,20,515,520, (例如,615,620,715,720,915,920,1015)和盖(25,625,725,925,1025)。 外芯(15,20,515,520,615,620,715,720,915,920,1015)围绕内芯,并且封盖包封芯。 内芯(10,610,710,910,1010,2010,3010)具有形成间隙(40,840,940,1040,2040,3040)的多个突起(35,935,1035,2035,3035,4035) ,4040),其中突起的自由端(45,2038)形成椭球形表面。 内芯由第一材料形成并且外芯由第二材料形成。 外芯是未卷绕的,并且第二材料设置在内芯的间隙(40,840,940,1040,2040,3040,4040)内,使得外芯的外表面基本为球形。 第一和第二材料具有实质上不同的材料特性。 在一个实施例中,突起具有扩大的自由端(45)。 在另一个实施例中,突起(2035)从基部(2036)向外逐渐变细。 在又一个实施例中,每个突起(3035,4035)的最大长度(L)大于最大宽度(W)。
