Heat insulating cup sleeve

Abstract

This invention provides a heat insulating cup sleeve formed by folding a blank and including a first heat insulating sheet having a first holding portion, a first extending portion, and a first fold line and a second heat insulating sheet having a second holding portion, a second extending portion, and a second fold line. The second fold line is connected with the first holding portion, and the first fold line is connected with the second holding portion. The first holding portion and the second holding portion are capable of being folded downward along the second fold line and the first fold line, respectively, to form an opening. When a cup is inserted into the opening, the first holding portion and the second holding portion press against an outer surface of the cup.
