Cup sleeve

Abstract

In one preferred embodiment, the invention is a cup holder sleeve comprising a quadrilateral planar sheet, defining a top and bottom concave edge parallel to each other, and a first and second edge at opposite ends of the sheet. The sheet is preferably air-laid non-woven cellulose, making it lightweight, biodegradable, heat transfer resistant, and cost-effective to transport.

What is claimed is: 
     
         1 . A cup holder sleeve comprising:
 a quadrilateral planar sheet defining a top and bottom edge parallel to each other, and a first and second edge at opposite ends of said quadrilateral planar sheet.   
     
     
         2 . The cup holder sleeve in  claim 1  wherein the quadrilateral planar sheet is comprised of non-woven cellulose. 
     
     
         3 . The cup holder sleeve in  claim 1  wherein the quadrilateral planar sheet is air laid. 
     
     
         4 . The cup holder sleeve in  claim 1  wherein the quadrilateral planar sheet is air laid at one hundred grams per meter squared. 
     
     
         5 . The cup holder sleeve in  claim 1  wherein the first and second edges each define a corresponding surface for fusing. 
     
     
         6 . The cup holder sleeve in  claim 5  wherein the first edge surface is fused to the second edge surface, to conform to and grip a cup to be passed through said cup holder sleeve. 
     
     
         7 . The cup holder sleeve in  claim 6  wherein the first edge surface is ultrasonically fused to the second edge surface to form a bond. 
     
     
         8 . The cup holder sleeve in  claim 1  wherein the quadrilateral planar sheet is further comprised of polyolefins to improve stretchability. 
     
     
         9 . The cup holder sleeve in  claim 1  wherein the sleeve bears a logo thereon, to advertise at least one select brand. 
     
     
         10 . The cup holder sleeve in  claim 1  wherein the quadrilateral planar sheet is two millimeters in thickness. 
     
     
         11 . The cup holder sleeve in  claim 1  wherein the quadrilateral planar sheet is approximately two millimeters in thickness. 
     
     
         12 . The cup holder sleeve in  claim 1  wherein the top and bottom edge are concave. 
     
     
         13 . A cup holder sleeve comprising:
 a quadrilateral planar sheet comprising a top and bottom edge parallel to each other, and a first and second edge at opposite ends of said quadrilateral planar sheet, the quadrilateral planar sheet comprising a non-woven, air laid cellulose.   
     
     
         14 . The cup holder sleeve in  claim 13  wherein the quadrilateral planar sheet is air laid at one hundred grams per meter squared. 
     
     
         15 . The cup holder sleeve in  claim 13  wherein the first and second edges are fused together. 
     
     
         16 . The cup holder sleeve in  claim 15  wherein the first edge surface is fused to the second edge surface, such that the sleeve conforms to a cup to be passed through said cup holder sleeve. 
     
     
         17 . The cup holder sleeve in  claim 15  wherein the first edge surface is ultrasonically fused to the second edge surface. 
     
     
         18 . The cup holder sleeve in  claim 13  wherein the sheet further comprised polyolefins to improve stretchability. 
     
     
         19 . The cup holder sleeve in  claim 13  wherein the sheet is air laid at about one hundred grams per meter squared. 
     
     
         20 . A cup holder sleeve comprising:
 a quadrilateral planar sheet comprising a top and bottom edge parallel to each other, and a first and second edge at opposite ends of said quadrilateral planar sheet, the quadrilateral planar sheet comprising a non-woven, air laid cellulose, the first and second edges are fused together such that the quadrilateral planar sheet conforms to a cup to be passed through the cup holder sleeve;   wherein the quadrilateral planar sheet is air laid at one hundred grams per meter squared.
