Grip tape

Abstract

A grip tape includes a base layer covered by a first adhesive layer. The first adhesive layer is partially covered by a second adhesive layer that is adjacent to one lateral edge of the first adhesive layer. The first adhesive layer, after being attached to the grip tape, is adhesive and used to wrap a grip portion of a baseball bat or the like. By applying pressing, the first adhesive layer is tightly affixed to a peripheral wall of the base layer. The second adhesive layer includes hot glue and is wound together with the grip tape around the baseball bat in a predetermined angle so that the second adhesive layer overlaps a felt sheet or other materials in the base layer. At last, after a process of thermocompression bond or thermal reaction, the both can be tightly bound with each other.

What is claimed is: 
     
         1 . A grip tape, being wound around a grip portion of an external tool and comprising:
 a base layer, having one side covered by a first adhesive layer that is so partially covered by a second adhesive layer that the second adhesive layer is adjacent to one lateral edge of the first adhesive layer,   wherein, the grip tape has a first end and a second end opposite to the first end, in which the first end is close to a terminal edge of the grip portion, and the second end is far from the terminal edge of the grip portion, and   wherein, when the first adhesive layer wraps the grip portion, the second adhesive layer partially overlaps an outer wall of the base layer.   
     
     
         2 . The grip tape of  claim 1 , wherein each of the two adhesive layers is adhered to, combined with, or bound to the base layer. 
     
     
         3 . The grip tape of  claim 2 , wherein the second adhesive layer takes up between 0.1% and 25% of an overall area of the first adhesive layer. 
     
     
         4 . The grip tape of  claim 3 , wherein the second adhesive layer takes up between 0.1% and 25% of an overall width of the first adhesive layer defined by the first and second ends. 
     
     
         5 . The grip tape of  claim 4 , wherein the second adhesive layer overlaps the base layer, and takes up between 0.1% and 25% of an overall area of the outer wall of the base layer. 
     
     
         6 . The grip tape of  claim 1 , wherein the second adhesive layer takes up between 0.1% and 25% of an overall area of the first adhesive layer. 
     
     
         7 . The grip tape of  claim 6 , wherein the second adhesive layer takes up between 0.1% and 25% of an overall width of the first adhesive layer defined by the first and second ends. 
     
     
         8 . The grip tape of  claim 7 , wherein the second adhesive layer overlaps the base layer, and takes up between 0.1% and 25% of an overall area of the outer wall of the base layer. 
     
     
         9 . The grip tape of  claim 1 , wherein the second adhesive layer takes up between 0.1% and 25% of an overall width of the first adhesive layer defined by the first and second ends. 
     
     
         10 . The grip tape of  claim 1 , wherein the second adhesive layer overlaps the base layer, and takes up between 0.1% and 25% of an overall width of the outer wall of the base layer defined by the first and second ends. 
     
     
         11 . The grip tape of  claim 2 , wherein the second adhesive layer overlaps the base layer, and takes up between 0.1% and 25% of an overall width of the outer wall of the base layer defined by the first and second ends. 
     
     
         12 . The grip tape of  claim 3 , wherein the second adhesive layer overlaps the base layer, and takes up between 0.1% and 25% of an overall width of the outer wall of the base layer defined by the first and second ends. 
     
     
         13 . The grip tape of  claim 4 , wherein the second adhesive layer overlaps the base layer, and takes up between 0.1% and 25% of an overall width of the outer wall of the base layer defined by the first and second ends. 
     
     
         14 . The grip tape of  claim 5 , wherein the second adhesive layer overlaps the base layer, and takes up between 0.1% and 25% of an overall width of the outer wall of the base layer defined by the first and second ends. 
     
     
         15 . The grip tape of  claim 6 , wherein the second adhesive layer overlaps the base layer, and takes up between 0.1% and 25% of an overall width of the outer wall of the base layer defined by the first and second ends. 
     
     
         16 . The grip tape of  claim 7 , wherein the second adhesive layer overlaps the base layer, and takes up between 0.1% and 25% of an overall width of the outer wall of the base layer defined by the first and second ends. 
     
     
         17 . The grip tape of  claim 8 , wherein the second adhesive layer overlaps the base layer, and takes up between 0.1% and 25% of an overall width of the outer wall of the base layer defined by the first and second ends. 
     
     
         18 . The grip tape of  claim 9 , wherein the second adhesive layer overlaps the base layer, and takes up between 0.1% and 25% of an overall width of the outer wall of the base layer defined by the first and second ends.
