Recyclable golf ball

Abstract

A recyclable golf ball is disclosed. The structure of the disclosed golf ball and/or the materials used to make the golf ball may enhance the ability to recycle the golf ball. As a result, the disclosed golf ball may decrease waste and the costs associated with acquiring and/or processing new materials. The golf ball may be made of materials that make it easier to separate the materials in a used golf ball for recycling. The golf ball may be made of materials having different densities. The golf ball may be made of materials having different melting points. The golf ball may be made of materials mixed with a magnetic additive.

         1 . A golf ball comprising:
 a first layer having a first melting point; and   a second layer enclosing the first layer, the second layer having a second melting point that is at least 50 degrees Celsius different from the first melting point.   
     
     
         2 . The golf ball according to  claim 1 , further comprising:
 a third layer disposed between the first layer and the second layer, the third layer having a third melting point that is at least 10 degrees Celsius different from the first melting point and the second melting point.   
     
     
         3 . The golf ball according to  claim 2 , further comprising:
 a fourth layer disposed between the second layer and the third layer, the fourth layer having a fourth melting point that is at least 10 degrees Celsius different from the first melting point, the second melting point, and the third melting point.   
     
     
         4 . The golf ball according to  claim 1 , wherein the first layer is a core layer and the second layer is a cover layer. 
     
     
         5 . The golf ball according to  claim 1 , further comprising a third layer that is a core layer made of a thermoset. 
     
     
         6 . The golf ball according to  claim 1 , further comprising a first intermediate layer disposed between the first layer and the second layer, wherein the first intermediate layer has a thickness ranging from about 1 μm to about 1 mm. 
     
     
         7 . The golf ball according to  claim 6 , wherein the first intermediate layer has a third melting point that is 10 degrees Celsius different from the first melting point and the second melting point. 
     
     
         8 . A golf ball comprising:
 a first layer;   a second layer surrounding the first layer;   a first intermediate layer disposed between the first layer and the second layer, wherein the first intermediate layer has a thickness ranging from about 1 μm to about 1 mm and the first intermediate layer is made of at least one of epoxy adhesives, acrylic adhesives, urethane adhesives, ethylene vinyl acetate adhesives, and rubber adhesives.   
     
     
         9 . The golf ball according to  claim 8 , wherein the first intermediate layer has a thickness ranging from about 1 μm to about 0.6 mm. 
     
     
         10 . The golf ball according to  claim 8 , further comprising:
 a third layer surrounding the second layer; and   a second intermediate layer disposed between the second layer and the third layer.   
     
     
         11 . A golf ball comprising:
 a first layer; and   a second layer enclosing the first layer,   wherein one of the first layer and the second layer includes magnetic additive.   
     
     
         12 . The golf ball according to  claim 11 , further comprising a third layer disposed between the first layer and the second layer, wherein the third layer includes magnetic additive. 
     
     
         13 . The golf ball according to  claim 12 , wherein one of the first layer and the second layer includes at least about 2 vol % to about 20 vol % less magnetic additive than the third layer. 
     
     
         14 . The golf ball according to  claim 12 , wherein one of the first layer and the second layer includes about 5 vol % to about 15 vol % of magnetic additive and the third layer includes about 7 vol % to about 35 vol % of magnetic additive. 
     
     
         15 . The golf ball according to  claim 11 , wherein the magnetic additive included in one of the first layer and the second layer is a ferrite magnetic powder. 
     
     
         16 . The golf ball according to  claim 11 , wherein the first layer is a thermoset containing magnetic additive. 
     
     
         17 . The golf ball according to  claim 11 , wherein the first layer is a thermoplastic containing magnetic additive. 
     
     
         18 . The golf ball according to  claim 11 , wherein the second layer is a thermoplastic containing magnetic additive. 
     
     
         19 . A golf ball comprising:
 a first layer made of a first material;   a second layer made of a second material enclosing the first layer; and   a plume made from the second material, wherein the plume is surrounded by the first material.   
     
     
         20 . The golf ball according to  claim 19 , wherein the plume has a fan-shaped cross-section. 
     
     
         21 . The golf ball according to  claim 19 , wherein the second layer has a thinned region radially spaced from the plume.
