Brown-bag-it insulation cup sleeve

Abstract

An insulating cup sleeve comprised of an arcuate strip with a top convex edge longer than a bottom concave edge, flaps on both edges, and two distal ends. The insulating cup sleeve contains a plurality of flaps on both the convex edge and concave edge that are to be folded over one another to create a multi-layered arcuate strip roughly one third its total original arcuate width. The insulating cup sleeve is assembled by interlocking the distal ends by engaging cuts made near each distal end originating from opposite edges of the arcuate strip

1 . A multi-layered insulating cup sleeve comprising:
 an arcuate strip having a top edge that is convex with a length and a plurality of integral flaps, a bottom edge that is concave with a length and a plurality of flaps, a distal end with a cut near that distal end that originates from the convex edge and transects ½ through the arcuate strip towards the concave edge, a second distal end with a cut near that distal end that originates from the concave edge and transects ½ through the arcuate strip towards the convex edge.   a plurality of flaps on both the convex and concave edges of the arcuate strip, wherein they are folded over 180 degrees to form a multi-layered insulating barrier.   
     
     
         2 . The sleeve of  claim 1  wherein the convex edge of the arcuate strip is longer than the concave edge. 
     
     
         3 . The sleeve of  claim 1  comprising a plurality of integral flaps, wherein the flaps of the concave and convex edges are to be folded over one another to create a multi layered arcuate strip that is assembled and used in conjunction with a conical container. 
     
     
         4 . The sleeve of  claim 1 , wherein the cuts near the distal ends can be interlocked to secure the sleeve so it can be placed around a conical container such as a paper coffee cup.
